230Exim version 4.69
231-----------------
232
4b3504d0
TK
233TK/01 Add preliminary DKIM support. Currently requires a forked version of
234 ALT-N's libdkim that I have put here:
235 http://duncanthrax.net/exim-experimental/
236
237 Note to Michael Haardt: I had to rename some vars in sieve.c. They
238 were called 'true' and it seems that C99 defines that as a reserved
239 keyword to be used with 'bool' variable types. That means you could
240 not include C99-style headers which use bools without triggering
241 build errors in sieve.c.
242

243NM/01 Bugzilla 592: --help option is handled incorrectly if exim is invoked

PH
256Exim version 4.68
257-----------------
258
259PH/01 Another patch from the Sieve maintainer.
260
6a3bceb1
PH
261PH/02 When an IPv6 address is converted to a string for single-key lookup
262 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
263 dots are used instead of colons so that keys in lsearch files need not
264 contain colons. This was done some time before quoting was made available
265 in lsearch files. However, iplsearch files do require colons in IPv6 keys
266 (notated using the quote facility) so as to distinguish them from IPv4
267 keys. This meant that lookups for IP addresses in host lists did not work
268 for iplsearch lookups.
269
270 This has been fixed by arranging for IPv6 addresses to be expressed with
271 colons if the lookup type is iplsearch. This is not incompatible, because
272 previously such lookups could never work.
273
274 The situation is now rather anomolous, since one *can* have colons in
275 ordinary lsearch keys. However, making the change in all cases is
276 incompatible and would probably break a number of configurations.
277
2e30fa9d
TK
278TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
279 version.
280
0806a9c5
MH
281MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
282 conversion specification without a maximum field width, thereby enabling
283 a rogue spamd server to cause a buffer overflow. While nobody in their
284 right mind would setup Exim to query an untrusted spamd server, an
285 attacker that gains access to a server running spamd could potentially
286 exploit this vulnerability to run arbitrary code as the Exim user.
287
ae276964
TK
288TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
289 $primary_hostname instead of what libspf2 thinks the hosts name is.
290
0f2cbd1b
MH
291MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
292 a directory entry by the name of the lookup key. Previously, if a
293 symlink pointed to a non-existing file or a file in a directory that
294 Exim lacked permissions to read, a lookup for a key matching that
295 symlink would fail. Now it is enough that a matching directory entry
296 exists, symlink or not. (Bugzilla 503.)
297
2b85bce7
PH
298PH/03 The body_linecount and body_zerocount variables are now exported in the

304 This means they are set thereafter only if the connection becomes
305 encrypted.

307PH/06 Added the client_condition to authenticators so that some can be skipped
308 by clients under certain conditions.

316 (without spaces) instead of just copying the configuration text.

325 way in which PCRE > 7.0 is built.

PH
332PH/16 Another patch from the Sieve maintainer.

334PH/17 Added the NOTQUIT ACL, based on a patch from Ted Cooper.
335
8932dffe
PH
336PH/18 If a system quota error occurred while trying to create the file for
337 a maildir delivery, the message "Mailbox is full" was not appended to the
338 bounce if the delivery eventually timed out. Change 4.67/27 below applied
339 only to a quota excession during the actual writing of the file.
d6a60c0f 340
ddea74fa 341PH/19 It seems that peer DN values may contain newlines (and other non-printing
48ed62d9
PH
342 characters?) which causes problems in log lines. The DN values are now
343 passed through string_printing() before being added to log lines.
344
ddea74fa 345PH/20 Added the "servers=" facility to MySQL and PostgreSQL lookups. (Oracle
b7670459
PH
346 and InterBase are left for another time.)
347
ddea74fa
PH
348PH/21 Added message_body_newlines option.

353
bc64a74d
PH
354PH/24 If the recipient of an error message contained an @ in the local part
355 (suitably quoted, of course), incorrect values were put in $domain and

PH
366PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
367 issue a MAIL command.
368
431b7361
PH
369PH/02 In an ACL statement such as
370
371 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
372
373 if a client was not listed at all, or was listed with a value other than
374 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
375 the condition was not true (as it should be), so access was not denied.
376 The bug was that the ! inversion was incorrectly passed on to the second
377 item. This has been fixed.
378
379PH/03 Added additional dnslists conditions == and =& which are different from
380 = and & when the dns lookup returns more than one IP address.
381
83da1223
PH
382PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
383 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
384
54fc8428
PH
385PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
386 FSYNC, which compiles an option called disable_fsync that allows for
387 bypassing fsync(). The documentation is heavily laced with warnings.
388

PH
391PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
392 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
393 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
394 including adding "make clean"; (3) Added -fPIC when compiling the test
395 dynamically loaded module, to get rid of a warning.
396
0e8a9471
MH
397MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
398 message fails, move_frozen_messages = true and ignore_bounce_errors_after
399 = 0s. The bug is otherwise harmless.
400
f0872424
PH
401PH/07 There was a bug in the dovecot authenticator such that the value of
402 $auth1 could be overwritten, and so not correctly preserved, after a
403 successful authentication. This usually meant that the value preserved by
404 the server_setid option was incorrect.

479PH/29 SMTP synchronization checks are implemented when a command is read -
480 there is a check that no more input is waiting when there shouldn't be

482 some time before the response is written. In this time, more input might
483 arrive, invalidly. So now there are extra checks after an ACL has run for
484 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
485 pipelining has not been advertised.

PH
559 the response to the final '.' that terminates a message, but only in the
560 case where the client has not sent further data following the '.'
561 (unfortunately, this is allowed). However, in many cases there won't be
562 any further data because there won't be any more messages to send. A call
563 to select() can be used: if it shows that the input is "ready", there is
564 either input waiting, or the socket has been closed. An attempt to read
565 the next input character can distinguish the two cases. Previously, Exim
58eb016e 566 would have sent an OK response which the client would never have see.

574Exim version 4.66
575-----------------
576
577PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
578 fixed by 4.65/MH/01 (is this a record?) are fixed:
579
580 (i) An empty string was always treated as zero by the numeric comparison
581 operators. This behaviour has been restored.
582
583 (ii) It is documented that the numeric comparison operators always treat
584 their arguments as decimal numbers. This was broken in that numbers
585 starting with 0 were being interpreted as octal.
586
587 While fixing these problems I realized that there was another issue that
588 hadn't been noticed. Values of message_size_limit (both the global option
589 and the transport option) were treated as octal if they started with 0.
590 The documentation was vague. These values are now always treated as
591 decimal, and I will make that clear in the documentation.

605PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
606 child addresses, Exim now panics and dies. Previously, because the count
607 is held in a short int, deliveries were likely to be lost. As such a
608 large number of recipients for a single message is ridiculous
609 (performance will be very, very poor), I have chosen to impose a limit
610 rather than extend the field.

616TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
617 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
635PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
636 callout verification, Exim cached a "reject" for the entire domain. This
637 is correct for most verifications, but it is not correct for a recipient
638 verification with use_sender or use_postmaster set, because in that case
639 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
640 case of MAIL FROM:<> rejection from other early rejections (e.g.
641 rejection of HELO). When verifying a recipient using a non-null MAIL
642 address, the cache is ignored if it shows MAIL FROM:<> rejection.
643 Whatever the result of the callout, the value of the domain cache is
644 left unchanged (for any other kind of callout, getting as far as trying
645 RCPT means that the domain itself is ok).

679PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
680 hostname. This is wrong, because it relates to the incoming message (and
681 probably the interface on which it is arriving) and not to the outgoing
682 callout (which could be using a different interface). This has been
683 changed to use the value of the helo_data option from the smtp transport
684 instead - this is what is used when a message is actually being sent. If
685 there is no remote transport (possible with a router that sets up host
686 addresses), $smtp_active_hostname is used.

14aa5a05 688PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 689 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
690 (a) The code assumed that strncpy() returns a negative number on buffer
691 overflow, which isn't the case. Replaced with Exim's string_format()
692 function.
693 (b) There were several signed/unsigned issues. I just did the minimum
694 hacking in of casts. There is scope for a larger refactoring.
695 (c) The code used strcasecmp() which is not a standard C function.
696 Replaced with Exim's strcmpic() function.
697 (d) The code set only $1; it now sets $auth1 as well.
698 (e) A simple test gave the error "authentication client didn't specify
699 service in request". It would seem that Dovecot has changed its
700 interface. Fortunately there's a specification; I followed it and
701 changed what the client sends and it appears to be working now.

706PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
707 address A is aliased to B and C, where B exists and C does not. Without
708 -v the output is "A verified" because verification stops after a
709 successful redirection if more than one address is generated. However,
710 with -v the child addresses are also verified. Exim was outputting "A
711 failed to verify" and then showing the successful verification for C,
712 with its parentage. It now outputs "B failed to verify", showing B's
713 parentage before showing the successful verification of C.

716 look up a TXT record in a specific list after matching in a combined

718
322050c2
PH
719PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
720 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
721 they consult the DNS. I had assumed they would set it the way they
722 wanted; and indeed my experiments on Linux seem to show that in some
723 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
724 To be on the safe side, however, I have now made the interface to
725 host_find_byname() similar to host_find_bydns(), with an argument
726 containing the DNS resolver options. The host_find_byname() function now
727 sets these options at its start, just as host_find_bydns() does. The smtp
728 transport options dns_qualify_single and dns_search_parents are passed to
729 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
730 of host_find_byname() use the default settings of RES_DEFNAMES
731 (qualify_single) but not RES_DNSRCH (search_parents).
732

733PH/17 Applied (a modified version of) Nico Erfurth's patch to make
734 spool_read_header() do less string testing, by means of a preliminary
735 switch on the second character of optional "-foo" lines. (This is
736 overdue, caused by the large number of possibilities that now exist.
737 Originally there were few.) While I was there, I also converted the
738 str(n)cmp tests so they don't re-test the leading "-" and the first
739 character, in the hope this might squeeze out yet more improvement.

PH
741PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
742 flag allowing group syntax was set by the header_syntax check but not
743 turned off, possible causing trouble later; (2) The flag was not being
744 set at all for the header_verify test, causing "group"-style headers to
745 be rejected. I have now set it in this case, and also caused header_
746 verify to ignore an empty address taken from a group. While doing this, I
747 came across some other cases where the code for allowing group syntax
748 while scanning a header line wasn't quite right (mostly, not resetting
749 the flag correctly in the right place). These bugs could have caused
750 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
752PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
753 with the "reply" argument non-NULL. The code, however (which originally
754 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
755 but it didn't always do it. This confused somebody who was copying the
756 code for some other use. I have removed all the tests.

PH
758PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
759 feature that was used to support insecure browsers during the U.S. crypto
760 embargo. It requires special client support, and Exim is probably the
761 only MTA that supported it -- and would never use it because real RSA is
762 always available. This code has been removed, because it had the bad
763 effect of slowing Exim down by computing (never used) parameters for the
764 RSA_EXPORT functionality.

766PH/21 On the advice of Timo Sirainen, added a check to the dovecot
767 authenticator to fail if there's a tab character in the incoming data

769 to be base64-encoded). Also added, on Timo's advice, the "secured" option
770 if the connection is using TLS or if the remote IP is the same as the
771 local IP, and the "valid-client-cert option" if a client certificate has
772 been verified.

803
804PH/30 Exim was sometimes attempting to deliver messages that had suffered
805 address errors (4xx response to RCPT) over the same connection as other
806 messages routed to the same hosts. Such deliveries are always "forced",
807 so retry times are not inspected. This resulted in far too many retries
808 for the affected addresses. The effect occurred only when there were more
809 hosts than the hosts_max_try setting in the smtp transport when it had
810 the 4xx errors. Those hosts that it had tried were not added to the list
811 of hosts for which the message was waiting, so if all were tried, there
812 was no problem. Two fixes have been applied:
813
814 (i) If there are any address or message errors in an SMTP delivery, none
815 of the hosts (tried or untried) are now added to the list of hosts
816 for which the message is waiting, so the message should not be a
817 candidate for sending over the same connection that was used for a
818 successful delivery of some other message. This seems entirely
819 reasonable: after all the message is NOT "waiting for some host".
820 This is so "obvious" that I'm not sure why it wasn't done
821 previously. Hope I haven't missed anything, but it can't do any
822 harm, as the worst effect is to miss an optimization.
823
824 (ii) If, despite (i), such a delivery is accidentally attempted, the
825 routing retry time is respected, so at least it doesn't keep
826 hammering the server.

842 written to the panic log as well as the main log, but it isn't really

844 removed the panic log writing for the ECONNRESET error when getsockname()

PH
847PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
848 runs only) independently of the message's sender address. This meant
849 that, if the 4xx error was in fact related to the sender, a different
850 message to the same recipient with a different sender could confuse
851 things. In particualar, this can happen when sending to a greylisting
852 server, but other circumstances could also provoke similar problems.
853 I have changed the default so that the retry time for these errors is now
854 based a combination of the sender and recipient addresses. This change
855 can be overridden by setting address_retry_include_sender=false in the
856 smtp transport.

1128 kind of temporary error. A kludge has been added to help with this.
1129 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1130 554 error is used if errno is still zero or contains ENOENT (which occurs

1214PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
1215 syntactically invalid From: or Reply-to: line, and a filter used this to
1216 generate an autoreply, and therefore failed to obtain an address for the
1217 autoreply, Exim could try to deliver to a non-existent relative file
1218 name, causing unrelated and misleading errors. What now happens is that
1219 it logs this as a hard delivery error, but does not attempt to create a
1220 bounce message.

1229PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
1230 compiled. In many other places in Exim, IPv6 addresses are always
1231 recognized, so I have changed this. It also means that IPv4 domain
1232 literals of the form [IPV4:n.n.n.n] are now always recognized.

1234PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
1235 used if the router is not running as root, for example, when verifying at
1236 ACL time, or when using -bh. The debugging output from this situation was
1237 non-existent - all you got was a failure to exec. I have made two
1238 changes:
1239
1240 (a) Failures to set uid/gid, the current directory, or a process leader
1241 in a subprocess such as that created by queryprogram now generate
1242 suitable debugging ouput when -d is set.
1243
1244 (b) The queryprogram router detects when it is not running as root,
1245 outputs suitable debugging information if -d is set, and then runs
1246 the subprocess without attempting to change uid/gid.

PH
1251PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1252 additional section of a DNS packet that returns MX or SRV records.
1253 Instead, it always explicitly searches for A/AAAA records. This avoids
1254 major problems that occur when a DNS server includes only records of one
1255 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1256 fixed another bug: if SRV records were looked up and the corresponding
1257 address records were *not* found in the additional section, the port
1258 values from the SRV records were lost.

PH
1260PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
1261 using the correct key (the original address) when searching the retry
1262 rules in order to find which one to use for generating the retry hint.
1263
064a94c9
PH
1264PH/18 If quota_warn_message contains a From: header, Exim now refrains from
1265 adding the default one. Similarly, if it contains a Reply-To: header, the
1266 errors_reply_to option, if set, is not used.
1267
727071f8
PH
1268PH/19 When calculating a retry time, Exim used to measure the "time since
1269 failure" by looking at the "first failed" field in the retry record. Now
1270 it does not use this if it is later than than the arrival time of the
1271 message. Instead it uses the arrival time. This makes for better
1272 behaviour in cases where some deliveries succeed, thus re-setting the
1273 "first failed" field. An example is a quota failure for a huge message
1274 when small messages continue to be delivered. Without this change, the
1275 "time since failure" will always be short, possible causing more frequent
1276 delivery attempts for the huge message than are intended.

1295
1296PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address

PH
1373PH/42 The content-scanning code uses fopen() to create files in which to put
1374 message data. Previously it was not paying any attention to the mode of
1375 the files. Exim runs with umask(0) because the rest of the code creates
1376 files with open(), and sets the required mode explicitly. Thus, these
1377 files were ending up world-writeable. This was not a big issue, because,
1378 being within the spool directory, they were not world-accessible. I have
1379 created a function called modefopen, which takes an additional mode
1380 argument. It sets umask(777), creates the file, chmods it to the required
1381 mode, then resets the umask. All the relevant calls to fopen() in the
1382 content scanning code have been changed to use this function.

1390PH/45 When the plaintext authenticator is running as a client, the server's
1391 challenges are checked to ensure they are valid base64 strings. By
1392 default, the authentication attempt is cancelled if an invalid string is
1393 received. Setting client_ignore_invalid_base64 true ignores these errors.
1394 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1395 they are received. Thus, the responses can be made to depend on the
1396 challenges. If an invalid string is ignored, an empty string is placed in
1397 the variable.

1411 of files (along with the size), even though it did not need this
1412 information. It now does the scan only if it needs to find either the

PH
1417PH/52 Two bugs concerned with error handling when the smtp transport is
1418 used in LMTP mode:
1419
1420 (i) Exim was not creating retry information for temporary errors given
1421 for individual recipients after the DATA command when the smtp transport
1422 was used in LMTP mode. This meant that they could be retried too
1423 frequently, and not timed out correctly.
1424
1425 (ii) Exim was setting the flag that allows error details to be returned
1426 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1427 recipients that were returned after the DATA command.
1428
1429PH/53 This is related to PH/52, but is more general: for any failing address,
1430 when detailed error information was permitted to be returned to the
1431 sender, but the error was temporary, then after the final timeout, only
1432 "retry timeout exceeded" was returned. Now it returns the full error as
1433 well as "retry timeout exceeded".

PH
1503PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1504 function verify_get_ident() calls ip_connect() to connect a socket, but
1505 if the "connect()" function timed out, ip_connect() used to close the
1506 socket. However, verify_get_ident() also closes the socket later, and in
1507 between Exim writes to the log, which may get opened at this point. When
1508 the socket was closed in ip_connect(), the log could get the same file
1509 descriptor number as the socket. This naturally causes chaos. The fix is
1510 not to close the socket in ip_connect(); the socket should be closed by
1511 the function that creates it. There was only one place in the code where
1512 this was missing, in the iplookup router, which I don't think anybody now
1513 uses, but I've fixed it anyway.

1536
1537 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1538 string.
1539
1540 (3) Reset the variables that are obtained from the first argument of
1541 ${prvscheck and used in the second argument before leaving the code,
1542 because their memory is reclaimed, so using them afterwards may do
1543 silly things.
1544
1545 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1546 one (it's much easier than Tom thought :-).

1570 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1571 not being looked up in the rDNS to get a host name, Exim was showing the
1572 IP address twice in Received: lines, even though the IP addresses were
1573 identical. For example:
1574
1575 Received: from [1.2.3.4] (helo=[1.2.3.4])
1576
1577 However, if the real host name was known, it was omitting the HELO data
1578 if it matched the actual IP address. This has been tidied up so that it
1579 doesn't show the same IP address twice.

1610 in the messages that it generates (bounce messages and others, such as
1611 warnings). In the case of bounce messages for non-SMTP mesages, there was
1612 also a typo: it was using "Auto_submitted" (underscore instead of
1613 hyphen). Since every message generated by Exim is necessarily in response
1614 to another message, thes have all been changed to:
1615
1616 Auto-Submitted: auto-replied
1617
1618 in accordance with these statements in the RFC:
1619
1620 The auto-replied keyword:
1621
1622 - SHOULD be used on messages sent in direct response to another
1623 message by an automatic process,
1624
1625 - MUST NOT be used on manually-generated messages,
1626
1627 - MAY be used on Delivery Status Notifications (DSNs) and Message
1628 Disposition Notifications (MDNs),
1629
1630 - MUST NOT be used on messages generated by automatic or periodic
1631 processes, except for messages which are automatic responses to
1632 other messages.

1668PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1669 canonical form (as documented). However, after a host name lookup from
1670 the IP address, check_host() was doing a simple string comparison with
1671 addresses acquired from the DNS when checking that the found name did
1672 have the original IP as one of its addresses. Since any found IPv6
1673 addresses are likely to be in abbreviated form, the comparison could
1674 fail. Luckily, there already exists a function for doing the comparison
1675 by converting both addresses to binary, so now that is used instead of
1676 the text comparison.
1677
96776534
PH
1678PH/20 There was another similar case to PH/19, when a complete host name was

1681 The same fix has been applied.

2060 the logs files are, rather than using the compiled in default. In our
2061 case the guess is not the same as the compiled default, so the script
2062 suddenly stopped working when I started to use syslog. The patch checks
2063 to see if log_file_path is "". If so, it attempts to read it from exim

2194PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2195 that changes the way the GnuTLS parameters are stored in the cache file.
2196 The new format can be generated externally. For backward compatibility,
2197 if the data in the cache doesn't make sense, Exim assumes it has read an
2198 old-format file, and it generates new data and writes a new file. This
2199 means that you can't go back to an older release without removing the
2200 file.
2201
2202PH/03 A redirect router that has both "unseen" and "one_time" set does not
2203 work if there are any delivery delays because "one_time" forces the
2204 parent to be marked "delivered", so its unseen clone is never tried
2205 again. For this reason, Exim now forbids the simultaneous setting of
2206 these two options.
2207
2208PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2209 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2210 entry if you want to know the details. The fix, however, neglected to
2211 consider the case when local delivery batching is involved. The test for
2212 "previously delivered" was not happening when checking to see if an
2213 address could be batched with a previous (undelivered) one; under
2214 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2215 address.

2220PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2221 header_syntax) but Exim was just ignoring anything given after a slash.
2222 In particular, this caused confusion with an attempt to use "verify =
2223 reverse_host_lookup/defer_ok". An error is now given when options are
2224 supplied for verify items that do not have them. (Maybe reverse_host_
2225 lookup should have a defer_ok option, but that's a different point.)

2227PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2279 ownership right at creation (otherwise, other Exim processes might see
2280 the file with the wrong ownership). There was no test for failure of this
2281 fork() call, which would lead to the process getting stuck as it waited
2282 for a non-existent subprocess. Forks do occasionally fail when resources
2283 run out. I reviewed all the other calls to fork(); they all seem to check

2289 the result was a log entry for a synchronization error with an empty
2290 string after "input=" when read() returned zero. If read() returned -1

PH
2303PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2304 hadn't been configured. The fix is from Juergen Kreileder, who
2305 understands it better than I do:
2306
2307 "Here's what I see happening with three configured cyrus_sasl
2308 authenticators configured (plain, login, cram-md5):
2309
2310 On startup auth_cyrus_sasl_init() gets called for each of these.
2311 This means three calls to sasl_listmech() without a specified mech_list.
2312 => SASL tests which mechs of all available mechs actually work
2313 => three warnings about OTP not working
2314 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2315
2316 With the patch, sasl_listmech() also gets called three times. But now
2317 SASL's mech_list option is set to the server_mech specified in the the
2318 authenticator. Or in other words, the answer from sasl_listmech()
2319 gets limited to just the mech you're testing for (which is different
2320 for each call.)
2321 => the return list contains just 'plain' or 'login', 'cram-md5' or
2322 nothing depending on the value of ob->server_mech.
2323

PH
2390PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2391 the grounds that routing the same address twice would always produce the
2392 same answer. This might have been true once, but it is certainly no
2393 longer true now. Routing a child address may depend on the previous
2394 routing that produced that child. Some complicated redirection strategies
2395 went wrong when messages had multiple recipients, and made Exim's
2396 behaviour dependent on the order in which the addresses were given.
2397
2398 I have moved the duplicate checking until after the routing is complete.
2399 Exim scans the addresses that are assigned to local and remote
2400 transports, and removes any duplicates. This means that more work will be
2401 done, as duplicates will always all be routed, but duplicates are
2402 presumably rare, so I don't expect this is of any significance.
2403
2404 For deliveries to pipes, files, and autoreplies, the duplicate checking
2405 still happens during the routing process, since they are not going to be
2406 routed further.

2408PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
2409 It corrects a timeout issue with spamd. This is Ian's comment: "The
2410 background is that sometimes spamd either never reads data from a
2411 connection it has accepted, or it never writes response data. The exiscan
2412 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2413 blindly assumes that writes won't block so it may never time out."

2427PH/42 Exim no longer gives details of delivery errors for specific addresses in
2428 bounce and delay warning messages, except in certain special cases, which
2429 are as follows:
2430
2431 (a) An SMTP error message from a remote host;
2432 (b) A message specified in a :fail: redirection;
2433 (c) A message specified in a "fail" command in a system filter;
2434 (d) A message specified in a FAIL return from the queryprogram router;
2435 (e) A message specified by the cannot_route_message router option.
2436
2437 In these cases only, Exim does include the error details in bounce and
2438 warning messages. There are also a few cases where bland messages such
2439 as "unrouteable address" or "local delivery error" are given.

2447PH/45 In a pipe transport, although a timeout while waiting for the pipe
2448 process to complete was treated as a delivery failure, a timeout while
2449 writing the message to the pipe was logged, but erroneously treated as a
2450 successful delivery. Such timeouts include transport filter timeouts. For
2451 consistency with the overall process timeout, these timeouts are now
2452 treated as errors, giving rise to delivery failures by default. However,
2453 there is now a new Boolean option for the pipe transport called
2454 timeout_defer, which, if set TRUE, converts the failures into defers for
2455 both kinds of timeout. A transport filter timeout is now identified in
2456 the log output.

2465A note about Exim versions 4.44 and 4.50
2466----------------------------------------
2467
2468Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2469changes of various kinds. As a consequence, a big documentation update was
2470needed. This delayed the release for rather longer than seemed good, especially
2471in the light of a couple of (minor) security issues. Therefore, the changes
2472that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2473release. So 4.44 and 4.50 are in effect two different branches that both start
2474from 4.43.
2475
2476I have left the 4.50 change log unchanged; it contains all the changes since
24774.43. The change log for 4.44 is below; many of its items are identical to
2478those for 4.50. This seems to be the most sensible way to preserve the
2479historical information.

PH
2485 1. Minor wording change to the doc/README.SIEVE file.
2486
139059f6 2487 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 2488 computation of the current number of files was incorrect.

2490 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2491 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2492 place.
2493

PH
2494 4. Give more explanation in the error message when the command for a transport
2495 filter fails to execute.
2496
b668c215
PH
2497 5. There are several places where Exim runs a non-Exim command in a
2498 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2499 was being done only for the command run by the queryprogram router. It is
2500 now done for all such subprocesses. The other cases are: ${run, transport
2501 filters, and the commands run by the lmtp and pipe transports.
2502
a494b1e1
PH
2503 6. Added CONFIGURE_GROUP build-time option.
2504
2505 7. Some older OS have a limit of 256 on the maximum number of file
2506 descriptors. Exim was using setrlimit() to set 1000 as a large value
2507 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2508 systems. I've change it so that if it can't get 1000, it tries for 256.

2510 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2511 was an oversight, and furthermore, ever since the addition of extra
2512 controls (e.g. 4.43/32), the checks on when to allow different forms of
2513 "control" were broken. There should now be diagnostics for all cases when a
2514 control that does not make sense is encountered.

252011. Tidy the search cache before the fork to do a delivery from a message
2521 received from the command line. Otherwise the child will trigger a lookup

2523 cached ldap connection that the parent has called unbind on.

PH
252512. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2526 of $address_data from the recipient verification was clobbered by the
2527 sender verification.
2528
252913. The value of address_data from a sender verification is now available in
2530 $sender_address_data in subsequent conditions in the ACL statement.

PH
255522. $host_address is now set to the target address during the checking of
2556 ignore_target_hosts.
2557
255823. When checking ignore_target_hosts for an ipliteral router, no host name was
2559 being passed; this would have caused $sender_host_name to have been used if
2560 matching the list had actually called for a host name (not very likely,
2561 since this list is usually IP addresses). A host name is now passed as
2562 "[x.x.x.x]".
2563
7d468ab8
PH
256424. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2565 code that specifies a non-restarting handler (typically sigaction() in
2566 modern systems) in an attempt to fix a rare and obscure crash bug.
2567
256825. Narrowed the window for a race in the daemon that could cause it to ignore
2569 SIGCHLD signals. This is not a major problem, because they are used only to
2570 wake it up if nothing else does.
2571
62c0818f
PH
257226. A malformed maildirsize file could cause Exim to calculate negative values
2573 for the mailbox size or file count. Odd effects could occur as a result.
2574 The maildirsize information is now recalculated if the size or filecount
2575 end up negative.
2576
26034054
PH
257727. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2578 support for a long time. Removed HAVE_SYS_VFS_H.

af66f652
PH
258028. Installed the latest version of exipick from John Jetmore.
2581
90af77f4
PH
258229. In an address list, if the pattern was not a regular expression, an empty
2583 subject address (from a bounce message) matched only if the pattern was an
2584 empty string. Non-empty patterns were not even tested. This was the wrong
2585 because it is perfectly reasonable to use an empty address as part of a
2586 database query. An empty address is now tested by patterns that are
2587 lookups. However, all the other forms of pattern expect the subject to
2588 contain a local part and a domain, and therefore, for them, an empty
2589 address still always fails if the pattern is not itself empty.
2590
d8ef3577
PH
259130. Exim went into a mad DNS loop when attempting to do a callout where the
2592 host was specified on an smtp transport, and looking it up yielded more
2593 than one IP address.
2594
5cb8cbc6
PH
259531. Re-factored the code for checking spool and log partition space into a
2596 function that finds that data and another that does the check. The former
2597 is then used to implement four new variables: $spool_space, $log_space,
2598 $spool_inodes, and $log_inodes.
2599
14702f5b
PH
260032. The RFC2047 encoding function was originally intended for short strings
2601 such as real names; it was not keeping to the 75-character limit for
2602 encoded words that the RFC imposes. It now respects the limit, and
2603 generates multiple encoded words if necessary. To be on the safe side, I
2604 have increased the buffer size for the ${rfc2047: expansion operator from
2605 1024 to 2048 bytes.
2606
063b1e99
PH
260733. It is now permitted to omit both strings after an "if" condition; if the
2608 condition is true, the result is "true". As before, when the second string
2609 is omitted, a false condition yields an empty string. This makes it less
2610 cumbersome to write custom ACL and router conditions.
2611
652e1b65
PH
261234. Failure to deliver a bounce message always caused it to be frozen, even if
2613 there was an errors_to setting on the router. The errors_to setting is now
2614 respected.
2615
6f0c9a4f
PH
261635. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2617 canonical form (fully expanded) before being placed in
2618 $sender_host_address.
2619
33397d19
PH
262036. The table in the code that translates DNS record types into text (T_A to
2621 "A" for instance) was missing entries for NS and CNAME. It is just possible
2622 that this could have caused confusion if both these types were looked up
2623 for the same domain, because the text type is used as part of Exim's
2624 per-process caching. But the chance of anyone hitting this buglet seems
2625 very small.
2626
7bb56e1f
PH
262737. The dnsdb lookup has been extended in a number of ways.
2628
2629 (1) There is a new type, "zns", which walks up the domain tree until it
2630 finds some nameserver records. It should be used with care.
2631
ea3bc19b
PH
2632 (2) There is a new type, "mxh", which is like "mx" except that it returns
2633 just the host names, not the priorities.
2634
2635 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2636 looked up. The behaviour when one of the lookups defers can be
2637 controlled by a keyword.
7bb56e1f 2638
ea3bc19b 2639 (4) It is now possible to specify the separator character for use when
7bb56e1f 2640 multiple records are returned.
33397d19 2641
0bcb2a0e
PH
264238. The dnslists ACL condition has been extended: it is now possible to supply
2643 a list of IP addresses and/or domains to be looked up in a particular DNS
2644 domain.

2ac0e484
PH
264639. Added log_selector=+queue_time_overall.
2647
4e1fde53
PH
264840. When running the queue in the test harness, wait just a tad after forking a
2649 delivery process, to get repeatability of debugging output.
2650
de365ded
PH
265141. Include certificate and key file names in error message when GnuTLS fails
2652 to set them up, because the GnuTLS error message doesn't include the name
2653 of the failing file when there is a problem reading it.
2654

PH
265944. The "Exiscan patch" is now merged into the mainline Exim source.
2660
266145. Sometimes the final signoff response after QUIT could fail to get
2662 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2663 < 0 before doing a fflush(). This bug looks as though it goes back to the
2664 introduction of TLS in release 3.20, but "sometimes" must have been rare
2665 because the tests only now provoked it.
2666

PH
266746. Reset the locale to "C" after calling embedded Perl, in case it was changed
2668 (this can affect the format of dates).

PH
267047. exim_tidydb, when checking for the continued existence of a message for
2671 which it has found a message-specific retry record, was not finding
2672 messages that were in split spool directories. Consequently, it was
2673 deleting retry records that should have stayed in existence.

PH
267548. Steve fixed some bugs in eximstats.
2676
267749. The SPA authentication driver was not abandoning authentication and moving
2678 on to the next authenticator when an expansion was forced to fail,
2679 contradicting the general specification for all authenticators. Instead it
2680 was generating a temporary error. It now behaves as specified.
2681
26dd5a95
PH
268250. The default ordering of permitted cipher suites for GnuTLS was pessimal
2683 (the order specifies the preference for clients). The order is now AES256,
2684 AES128, 3DES, ARCFOUR128.

268651. Small patch to Sieve code - explicitly set From: when generating an
2687 autoreply.

PH
268952. Exim crashed if a remote delivery caused a very long error message to be
2690 recorded - for instance if somebody sent an entire SpamAssassin report back
2691 as a large number of 550 error lines. This bug was coincidentally fixed by
2692 increasing the size of one of Exim's internal buffers (big_buffer) that
2693 happened as part of the Exiscan merge. However, to be on the safe side, I
2694 have made the code more robust (and fixed the comments that describe what
2695 is going on).
2696
55ee9ee3
PH
269753. Now that there can be additional text after "Completed" in log lines (if
2698 the queue_time_overall log selector is set), a one-byte patch to exigrep
2699 was needed to allow it to recognize "Completed" as not the last thing in
2700 the line.
2701

PH
270254. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2703 patch that reportedly fixes this has been added. I am not expert enough to
2704 create a test for it. This is what the patch creator wrote:
2705
2706 "I found a little strange behaviour of ldap code when working with
2707 Windows 2003 AD Domain, where users was placed in more than one
2708 Organization Units. When I tried to give exim partial DN, the exit code
2709 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2710 But simultaneously result of request was absolutely normal ldap result,
2711 so I produce this patch..."
2712
3295e65b
PH
2713 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2714 REFERENCE, so I have modified the code to exclude the patch when that macro
2715 is not defined.
2716
7102e136
PH
271755. Some experimental protocols are using DNS PTR records for new purposes. The
2718 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2719 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2720 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
272858. The exicyclog utility now does better if the number of log files to keep

PH
273159. Two changes related to the smtp_active_hostname option:
2732
2733 (1) $smtp_active_hostname is now available as a variable.
2734 (2) The default for smtp_banner uses $smtp_active_hostname instead
2735 of $primary_hostname.
2736
b975ba52
PH
273760. The host_aton() function is supposed to be passed a string that is known
2738 to be a valid IP address. However, in the case of IPv6 addresses, it was
2739 not checking this. This is a hostage to fortune. Exim now panics and dies
2740 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2741 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2742 components; fortuitously, this particular loophole had already been fixed
2743 by change 4.50/55 above.
2744
2745 If there are any other similar loopholes, the new check in host_aton()
2746 itself should stop them being exploited. The report I received stated that
2747 data on the command line could provoke the exploit when Exim was running as
2748 exim, but did not say which command line option was involved. All I could
2749 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2750 running as the user.

PH
276163. The daemon start-up calls getloadavg() while still root for those OS that
2762 need the first call to be done as root, but it missed one case: when
2763 deliver_queue_load_max is set with deliver_drop_privilege. This is
2764 necessary for the benefit of the queue runner, because there is no re-exec
2765 when deliver_drop_privilege is set.

86b8287f
PH
276764. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
2768 This has been fixed.
2769
60dc5e56
PH
277065. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2771 was in use, was not putting the data itself into the right store pool;
2772 consequently, it could be overwritten for a subsequent message in the same
2773 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2774 the caching.)
2775

PH
277666. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
277867. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2779 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2780 the function were treating the return as a boolean value, which happened to
2781 work because 0=false and not-0=true, but is not correct code.
2782
7e634d24
PH
278368. The host_aton() function was not handling scoped IPv6 addresses (those
2784 with, for example, "%eth0" on the end) correctly.

PH
278669. Fixed some compiler warnings in acl.c for the bitmaps specified with

PH
279070. If an address verification called from an ACL failed, and did not produce a
2791 user-specific message (i.e. there was only a "system" message), nothing was
2792 put in $acl_verify_message. In this situation, it now puts the system
2793 message there.

PH
279571. Change 4.23/11 added synchronization checking at the start of an SMTP
2796 session; change 4.31/43 added the unwanted input to the log line - except
2797 that it did not do this in the start of session case. It now does.
2798
c9bdd01c
PH
279972. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2800 This is wrong and can cause the other end to generate a synchronization
2801 error if it is another Exim or anything else that does the synchronization
2802 check. A QUIT command is no longer sent after a timeout.
2803

PH
280473. $host_lookup_deferred has been added, to make it easier to detect DEFERs
2805 during host lookups.
2806

PH
280774. The defer_ok option of callout verification was not working if it was used
2808 when verifying addresses in header lines, that is, for this case:
2809
2810 verify = header_sender/callout=defer_ok
2811
76a2d7ba
PH
281275. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2813 those file descriptors could be used for SMTP connections. If anything
2814 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2815 could be sent to the SMTP client, causing chaos. The daemon now opens
2816 stdin, stdout, and stderr to /dev/null when it puts itself into the
2817 background.
2818
281976. Arrange for output from Perl's "warn" command to be written to Exim's main
2820 log by default. The user can override this with suitable Perl magic.
2821
04f7d5b9
PH
282277. The use of log_message on a "discard" ACL verb, which is supposed to add to
2823 the log message when discard triggers, was not working for the DATA ACL or
2824 for the non-SMTP ACL.
2825
bc60667e
PH
282678. Error message wording change in sieve.c.
2827
bb6e88ff
PH
282879. If smtp_accept_max_per_host was set, the number of connections could be
2829 restricted to fewer than expected, because the daemon was trying to set up
2830 a new connection before checking whether the processes handling previous
2831 connections had finished. The check for completed processes is now done
2832 earlier. On busy systems, this bug wouldn't be noticed because something
2833 else would have woken the daemon, and it would have reaped the completed
2834 process earlier.
2835
1e70f85b
PH
283680. If a message was submitted locally by a user whose login name contained one
2837 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2838 It caused a spool format error. I have fixed the spool reading code. A
2839 related problem was that the "from" clause in the Received: line became
2840 illegal because of the space(s). It is now covered by ${quote_local_part.
2841
284281. Included the latest eximstats from Steve (adds average sizes to HTML Top
2843 tables).

2856----------------------------------------------------
2857See the note above about the 4.44 and 4.50 releases.
2858----------------------------------------------------
2859
2860
2861Exim version 4.44
2862-----------------
2863
2864 1. Change 4.43/35 introduced a bug that caused file counts to be
2865 incorrectly computed when quota_filecount was set in an appendfile
2866 transport
2867
2868 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2869 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2870 place.
2871
2872 3. Give more explanation in the error message when the command for a transport
2873 filter fails to execute.
2874
2875 4. There are several places where Exim runs a non-Exim command in a
2876 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2877 was being done only for the command run by the queryprogram router. It is
2878 now done for all such subprocesses. The other cases are: ${run, transport
2879 filters, and the commands run by the lmtp and pipe transports.
2880
2881 5. Some older OS have a limit of 256 on the maximum number of file
2882 descriptors. Exim was using setrlimit() to set 1000 as a large value
2883 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2884 systems. I've change it so that if it can't get 1000, it tries for 256.
2885
2886 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2887 was an oversight, and furthermore, ever since the addition of extra
2888 controls (e.g. 4.43/32), the checks on when to allow different forms of
2889 "control" were broken. There should now be diagnostics for all cases when a
2890 control that does not make sense is encountered.
2891
2892 7. $recipients is now available in the predata ACL (oversight).
2893
2894 8. Tidy the search cache before the fork to do a delivery from a message
2895 received from the command line. Otherwise the child will trigger a lookup
2896 failure and thereby defer the delivery if it tries to use (for example) a
2897 cached ldap connection that the parent has called unbind on.
2898
2899 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2900 of $address_data from the recipient verification was clobbered by the
2901 sender verification.
2902
290310. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
2904 was its contents. (It was OK if the option was not defined at all.)
2905
290611. A "Completed" log line is now written for messages that are removed from
2907 the spool by the -Mrm option.
2908
290912. $host_address is now set to the target address during the checking of
2910 ignore_target_hosts.
2911
291213. When checking ignore_target_hosts for an ipliteral router, no host name was
2913 being passed; this would have caused $sender_host_name to have been used if
2914 matching the list had actually called for a host name (not very likely,
2915 since this list is usually IP addresses). A host name is now passed as
2916 "[x.x.x.x]".
2917
291814. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2919 code that specifies a non-restarting handler (typically sigaction() in
2920 modern systems) in an attempt to fix a rare and obscure crash bug.
2921
292215. Narrowed the window for a race in the daemon that could cause it to ignore
2923 SIGCHLD signals. This is not a major problem, because they are used only to
2924 wake it up if nothing else does.
2925
292616. A malformed maildirsize file could cause Exim to calculate negative values
2927 for the mailbox size or file count. Odd effects could occur as a result.
2928 The maildirsize information is now recalculated if the size or filecount
2929 end up negative.
2930
293117. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2932 support for a long time. Removed HAVE_SYS_VFS_H.
2933
ea3a6f44 293418. Updated exipick to current release from John Jetmore.
bbe902f0
PH
2935
293619. Allow an empty sender to be matched against a lookup in an address list.
2937 Previously the only cases considered were a regular expression, or an
2938 empty pattern.
2939
294020. Exim went into a mad DNS lookup loop when doing a callout where the
2941 host was specified on the transport, if the DNS lookup yielded more than
2942 one IP address.
2943
ea3a6f44
NM
294421. The RFC2047 encoding function was originally intended for short strings
2945 such as real names; it was not keeping to the 75-character limit for
2946 encoded words that the RFC imposes. It now respects the limit, and
2947 generates multiple encoded words if necessary. To be on the safe side, I
2948 have increased the buffer size for the ${rfc2047: expansion operator from
2949 1024 to 2048 bytes.
bbe902f0 2950
ea3a6f44
NM
295122. Failure to deliver a bounce message always caused it to be frozen, even if
2952 there was an errors_to setting on the router. The errors_to setting is now
2953 respected.
bbe902f0
PH
2954
295523. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2956 canonical form (fully expanded) before being placed in
2957 $sender_host_address.
2958
295924. Updated eximstats to version 1.33
2960
ea3a6f44
NM
296125. Include certificate and key file names in error message when GnuTLS fails
2962 to set them up, because the GnuTLS error message doesn't include the name
2963 of the failing file when there is a problem reading it.
bbe902f0
PH
2964
296526. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 2966 As per change 25.
bbe902f0 2967
ea3a6f44
NM
296827. Reset the locale to "C" after calling embedded Perl, in case it was changed
2969 (this can affect the format of dates).
bbe902f0 2970
ea3a6f44
NM
297128. exim_tidydb, when checking for the continued existence of a message for
2972 which it has found a message-specific retry record, was not finding
2973 messages that were in split spool directories. Consequently, it was
2974 deleting retry records that should have stayed in existence.
bbe902f0
PH
2975
297629. eximstats updated to version 1.35
2977 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
2978 1.35 - bugfix such that pie charts by volume are generated correctly
2979
ea3a6f44
NM
298030. The SPA authentication driver was not abandoning authentication and moving
2981 on to the next authenticator when an expansion was forced to fail,
2982 contradicting the general specification for all authenticators. Instead it
2983 was generating a temporary error. It now behaves as specified.
bbe902f0 2984
ea3a6f44
NM
298531. The default ordering of permitted cipher suites for GnuTLS was pessimal
2986 (the order specifies the preference for clients). The order is now AES256,
2987 AES128, 3DES, ARCFOUR128.
bbe902f0 2988
ea3a6f44
NM
298931. Small patch to Sieve code - explicitly set From: when generating an
2990 autoreply.
bbe902f0 2991
ea3a6f44
NM
299232. Exim crashed if a remote delivery caused a very long error message to be
2993 recorded - for instance if somebody sent an entire SpamAssassin report back
2994 as a large number of 550 error lines. This bug was coincidentally fixed by
2995 increasing the size of one of Exim's internal buffers (big_buffer) that
2996 happened as part of the Exiscan merge. However, to be on the safe side, I
2997 have made the code more robust (and fixed the comments that describe what
2998 is going on).
bbe902f0 2999
ea3a6f44
NM
300033. Some experimental protocols are using DNS PTR records for new purposes. The
3001 keys for these records are domain names, not reversed IP addresses. The
3002 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3003 leaves it alone. Component reversal etc. now happens only for IP addresses.
bbe902f0
PH
3004 CAN-2005-0021
3005
ea3a6f44
NM
300634. The host_aton() function is supposed to be passed a string that is known
3007 to be a valid IP address. However, in the case of IPv6 addresses, it was
3008 not checking this. This is a hostage to fortune. Exim now panics and dies
3009 if the condition is not met. A case was found where this could be provoked
3010 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3011 components; fortuitously, this particular loophole had already been fixed
3012 by change 4.50/55 or 4.44/33 above.
3013
3014 If there are any other similar loopholes, the new check in host_aton()
3015 itself should stop them being exploited. The report I received stated that
3016 data on the command line could provoke the exploit when Exim was running as
3017 exim, but did not say which command line option was involved. All I could
3018 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3019 running as the user.

3020 CAN-2005-0021
3021
ea3a6f44
NM
302235. There was a buffer overflow vulnerability in the SPA authentication code
3023 (which came originally from the Samba project). I have added a test to the
3024 spa_base64_to_bits() function which I hope fixes it.
bbe902f0
PH
3025 CAN-2005-0022
3026
ea3a6f44
NM
302736. The daemon start-up calls getloadavg() while still root for those OS that
3028 need the first call to be done as root, but it missed one case: when
3029 deliver_queue_load_max is set with deliver_drop_privilege. This is
3030 necessary for the benefit of the queue runner, because there is no re-exec
3031 when deliver_drop_privilege is set.
bbe902f0 3032
ea3a6f44
NM
303337. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3034 was in use, was not putting the data itself into the right store pool;
3035 consequently, it could be overwritten for a subsequent message in the same
3036 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3037 the caching.)
bbe902f0 3038
ea3a6f44
NM
303938. Sometimes the final signoff response after QUIT could fail to get
3040 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3041 < 0 before doing a fflush(). This bug looks as though it goes back to the
3042 introduction of TLS in release 3.20, but "sometimes" must have been rare
3043 because the tests only now provoked it.

3046Exim version 4.43
3047-----------------
3048
3049 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3050 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3051 Now it returns an integer. A number of calls were still expecting a T/F
3052 return. Fortuitously, in all cases, the tests worked in OK situations,
3053 which is the norm. However, things would have gone wrong on any write
3054 failures on the smtp file descriptor. This function is used when sending
3055 messages over SMTP and also when doing verify callouts.
3056
3057 2. When Exim is called to do synchronous delivery of a locally submitted
3058 message (the -odf or -odi options), it no longer closes stderr before doing
3059 the delivery.
3060
3061 3. Implemented the mua_wrapper option.
3062
3063 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3064
3065 5. Implemented the functions header_remove(), header_testname(),
3066 header_add_at_position(), and receive_remove_recipient(), and exported them
3067 to local_scan().
3068
3069 6. If an ACL "warn" statement specified the addition of headers, Exim already
3070 inserted X-ACL-Warn: at the start if there was no header name. However, it
3071 was not making this test for the second and subsequent header lines if
3072 there were newlines in the string. This meant that an invalid header could
3073 be inserted if Exim was badly configured.
3074
3075 7. Allow an ACL "warn" statement to add header lines at the start or after all
3076 the Received: headers, as well as at the end.
3077
3078 8. Added the rcpt_4xx retry error code.
3079
3080 9. Added postmaster_mailfrom=xxx to callout verification option.
3081
308210. Added mailfrom=xxxx to the callout verification option, for verify=
3083 header_sender only.
3084
308511. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3086 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3087
308812. Inserted some casts to stop certain compilers warning when using pointer
3089 differences as field lengths or precisions in printf-type calls (mostly
3090 affecting debugging statements).
3091
309213. Added optional readline() support for -be (dynamically loaded).
3093
309414. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3095 same clock tick as a message's arrival, so that its received time was the
3096 same as the "first fail" time on the retry record, and that message
3097 remained on the queue past the ultimate address timeout, every queue runner
3098 would try a delivery (because it was past the ultimate address timeout) but
3099 after another failure, the ultimate address timeout, which should have then
3100 bounced the address, did not kick in. This was a "< instead of <=" error;
3101 in most cases the first failure would have been in the next clock tick
3102 after the received time, and all would be well.
3103
310415. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3105 being recognized when the domain list was tested by the match_domain
3106 condition in an expansion string.
3107
310816. Added the ${str2b64: operator.
3109
311017. Exim was always calling setrlimit() to set a large limit for the number of
3111 processes, without checking whether the existing limit was already
3112 adequate. (It did check for the limit on file descriptors.) Furthermore,
3113 errors from getrlimit() and setrlimit() were being ignored. Now they are
3114 logged to the main and panic logs, but Exim does carry on, to try to do its
3115 job under whatever limits there are.
3116
311718. Imported PCRE 5.0.
3118
311919. Trivial typo in log message " temporarily refused connection" (the leading
3120 space).
3121
312220. If the log selector return_path_on_delivery was set and an address was
3123 redirected to /dev/null, the delivery process crashed because it assumed
3124 that a return path would always be set for a "successful" delivery. In this
3125 case, the whole delivery is bypassed as an optimization, and therefore no
3126 return path is set.
3127
312821. Internal re-arrangement: the function for sending a challenge and reading
3129 a response while authentication was assuming a zero-terminated challenge
3130 string. It's now changed to take a pointer and a length, to allow for
3131 binary data in such strings.
3132
313322. Added the cyrus_sasl authenticator (code supplied by MBM).
3134
313523. Exim was not respecting finduser_retries when seeking the login of the
3136 uid under which it was called; it was always trying 10 times. (The default
3137 setting of finduser_retries is zero.) Also, it was sleeping after the final
3138 failure, which is pointless.
3139
314024. Implemented tls_on_connect_ports.
3141
314225. Implemented acl_smtp_predata.
3143
314426. If the domain in control=submission is set empty, Exim assumes that the
3145 authenticated id is a complete email address when it generates From: or
3146 Sender: header lines.
3147
314827. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3149 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3150 chown and chgrp in /bin and hostname in /usr/bin.
3151
315228. Exim was keeping the "process log" file open after each use, just as it
3153 does for the main log. This opens the possibility of it remaining open for
3154 long periods when the USR1 signal hits a daemon. Occasional processlog
3155 errors were reported, that could have been caused by this. Anyway, it seems
3156 much more sensible not to leave this file open at all, so that is what now
3157 happens.
3158
315929. The long-running daemon process does not normally write to the log once it
3160 has entered its main loop, and it closes the log before doing so. This is
3161 so that log files can straightforwardly be renamed and moved. However,
3162 there are a couple of unusual error situations where the daemon does write
3163 log entries, and I had neglected to close the log afterwards.
3164
316530. The text of an SMTP error response that was received during a remote
3166 delivery was being truncated at 512 bytes. This is too short for some of
3167 the long messages that one sometimes sees. I've increased the limit to
3168 1024.
3169
317031. It is now possible to make retry rules that apply only when a message has a
3171 specific sender, in particular, an empty sender.
3172
317332. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3174 it possible to be selective about when SMTP synchronization is enforced.
3175
317633. Added "control = caseful_local_part" and "control = "caselower_local_part".
3177
317832. Implemented hosts_connection_nolog.
3179
318033. Added an ACL for QUIT.
3181
318234. Setting "delay_warning=" to disable warnings was not working; it gave a
3183 syntax error.
3184
318535. Added mailbox_size and mailbox_filecount to appendfile.
3186
318736. Added control = no_multiline_responses to ACLs.
3188
318937. There was a bug in the logic of the code that waits for the clock to tick
3190 in the case where the clock went backwards by a substantial amount such
3191 that the microsecond fraction of "now" was more than the microsecond
3192 fraction of "then" (but the whole seconds number was less).
3193
319438. Added support for the libradius Radius client library this is found on
3195 FreeBSD (previously only the radiusclient library was supported).
3196
3197
3198Exim version 4.42
3199-----------------
3200
3201 1. When certain lookups returned multiple values in the form name=value, the
3202 quoting of the values was not always being done properly. Specifically:
3203 (a) If the value started with a double quote, but contained no whitespace,
3204 it was not quoted.
3205 (b) If the value contained whitespace other than a space character (i.e.
3206 tabs or newlines or carriage returns) it was not quoted.
3207 This fix has been applied to the mysql and pgsql lookups by writing a
3208 separate quoting function and calling it from the lookup code. The fix
3209 should probably also be applied to nisplus, ibase and oracle lookups, but
3210 since I cannot test any of those, I have not disturbed their existing code.
3211
3212 2. A hit in the callout cache for a specific address caused a log line with no
3213 reason for rejecting RCPT. Now it says "Previous (cached) callout
3214 verification failure".
3215
3216 3. There was an off-by-one bug in the queryprogram router. An over-long
3217 return line was truncated at 256 instead of 255 characters, thereby
3218 overflowing its buffer with the terminating zero. As well as fixing this, I
3219 have increased the buffer size to 1024 (and made a note to document this).
3220
3221 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3222 when Exim is waiting for an SMTP response from a remote server, Exim
3223 restarts its select() call on the socket, thereby resetting its timeout.
3224 This is not a problem when such interrupts are rare. Somebody set up a cron
3225 job to run exiwhat every 2 minutes, which is less than the normal select()
3226 timeout (5 or 10 minutes). This meant that the select() timeout never
3227 kicked in because it was always reset. I have fixed this by comparing the
3228 time when an interrupt arrives with the time at the start of the first call
3229 to select(). If more time than the timeout has elapsed, the interrupt is
3230 treated as a timeout.
3231
3232 5. Some internal re-factoring in preparation for the addition of Sieve
3233 extensions (by MH). In particular, the "personal" test is moved to a
3234 separate function, and given an option for scanning Cc: and Bcc: (which is
3235 not set for Exim filters).
3236
3237 6. When Exim created an email address using the login of the caller as the
3238 local part (e.g. when creating a From: or Sender: header line), it was not
3239 quoting the local part when it contained special characters such as @.
3240
3241 7. Installed new OpenBSD configuration files.
3242
3243 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3244 try to make them clearer.
3245
3246 9. Callout options, other than the timeout value, were being ignored when
3247 verifying sender addresses in header lines. For example, when using
3248
3249 verify = header_sender/callout=no_cache
3250
3251 the cache was (incorrectly) being used.
3252
325310. Added a missing instance of ${EXE} to the exim_install script; this affects
3254 only the Cygwin environment.
3255
325611. When return_path_on_delivery was set as a log selector, if different remote
3257 addresses in the same message used different return paths and parallel
3258 remote delivery occurred, the wrong values would sometimes be logged.
3259 (Whenever a remote delivery process finished, the return path value from
3260 the most recently started remote delivery process was logged.)
3261
326212. RFC 3848 specifies standard names for the "with" phrase in Received: header
3263 lines when AUTH and/or TLS are in use. This is the "received protocol"
3264 field. Exim used to use "asmtp" for authenticated SMTP, without any
3265 indication (in the protocol name) for TLS use. Now it follows the RFC and
3266 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3267 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3268 names appear in log lines as well as in Received: header lines.
3269
327013. Installed MH's patches for Sieve to add the "copy" and "vacation"
3271 extensions, and comparison tests, and to fix some bugs.
3272
327314. Changes to the "personal" filter test:
3274
3275 (1) The test was buggy in that it was just doing the equivalent of
3276 "contains" tests on header lines. For example, if a user's address was
3277 anne@some.where, the "personal" test would incorrectly be true for
3278
3279 To: susanne@some.where
3280
3281 This test is now done by extracting each address from the header in turn,
3282 and checking the entire address. Other tests that are part of "personal"
3283 are now done using regular expressions (for example, to check local parts
3284 of addresses in From: header lines).
3285
3286 (2) The list of non-personal local parts in From: addresses has been
3287 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3288 taken from the Sieve specification recommendations.
3289
3290 (3) If the message contains any header line starting with "List-" it is
3291 treated as non-personal.
3292
3293 (4) The test for "circular" in the Subject: header line has been removed
3294 because it now seems ill-conceived.
3295
329615. Minor typos in src/EDITME comments corrected.
3297
329816. Installed latest exipick from John Jetmore.
3299
330017. If headers_add on a router specified a text string that was too long for
3301 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3302 of string_sprintf() is now avoided.
3303
330418. $message_body_size was not set (it was always zero) when running the DATA
3305 ACL and the local_scan() function.
3306
330719. For the "mail" command in an Exim filter, no default was being set for
3308 the once_repeat time, causing a random time value to be used if "once" was
3309 specified. (If the value happened to be <= 0, no repeat happened.) The
3310 default is now 0s, meaning "never repeat". The "vacation" command was OK
3311 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3312 (I found it when inspecting the code).
3313
331420. There is now an overall timeout for performing a callout verification. It
3315 defaults to 4 times the callout timeout, which applies to individual SMTP
3316 commands during the callout. The overall timeout applies when there is more
3317 than one host that can be tried. The timeout is checked before trying the
3318 next host. This prevents very long delays if there are a large number of
3319 hosts and all are timing out (e.g. when the network connections are timing
3320 out). The value of the overall timeout can be changed by specifying an
3321 additional sub-option for "callout", called "maxwait". For example:
3322
3323 verify = sender/callout=5s,maxwait=20s
3324
332521. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3326 to the end before writing, but this should make it even safer).
3327
332822. Exim was forgetting that it had advertised PIPELINING for the second and
3329 subsequent messages on an SMTP connection. It was also not resetting its
3330 memory on STARTTLS and an internal HELO.
3331
333223. When Exim logs an SMTP synchronization error within a session, it now
3333 records whether PIPELINING has been advertised or not.
3334
333524. Added 3 instances of "(long int)" casts to time_t variables that were being
3336 formatted using %ld, because on OpenBSD (and perhaps others), time_t is int
3337 rather than long int.
3338
333925. Installed the latest Cygwin configuration files from the Cygwin maintainer.
3340
334126. Added the never_mail option to autoreply.
3342
3343
3344Exim version 4.41
3345-----------------
3346
3347 1. A reorganization of the code in order to implement 4.40/8 caused a daemon
3348 crash if the getsockname() call failed; this can happen if a connection is
3349 closed very soon after it is established. The problem was simply in the
3350 order in which certain operations were done, causing Exim to try to write
3351 to the SMTP stream before it had set up the file descriptor. The bug has
3352 been fixed by making things happen in the correct order.
3353
3354
3355Exim version 4.40
3356-----------------
3357
3358 1. If "drop" was used in a DATA ACL, the SMTP output buffer was not flushed
3359 before the connection was closed, thus losing the rejection response.
3360
3361 2. Commented out the definition of SOCKLEN_T in os.h-SunOS5. It is needed for
3362 some early Solaris releases, but causes trouble in current releases where
3363 socklen_t is defined.
3364
3365 3. When std{in,out,err} are closed, re-open them to /dev/null so that they
3366 always exist.
3367
3368 4. Minor refactoring of os.c-Linux to avoid compiler warning when IPv6 is not
3369 configured.
3370
3371 5. Refactoring in expand.c to improve memory usage. Pre-allocate a block so
3372 that releasing the top of it at the end releases what was used for sub-
3373 expansions (unless the block got too big). However, discard this block if
3374 the first thing is a variable or header, so that we can use its block when
3375 it is dynamic (useful for very large $message_headers, for example).
3376
3377 6. Lookups now cache *every* query, not just the most recent. A new, separate
3378 store pool is used for this. It can be recovered when all lookup caches are
3379 flushed. Lookups now release memory at the end of their result strings.
3380 This has involved some general refactoring of the lookup sources.
3381
3382 7. Some code has been added to the store_xxx() functions to reduce the amount
3383 of flapping under certain conditions.
3384
3385 8. log_incoming_interface used to affect only the <= reception log lines. Now
3386 it causes the local interface and port to be added to several more SMTP log
3387 lines, for example "SMTP connection from", and rejection lines.
3388
3389 9. The Sieve author supplied some patches for the doc/README.SIEVE file.
3390
339110. Added a conditional definition of _BSD_SOCKLEN_T to os.h-Darwin.
3392
339311. If $host_data was set by virtue of a hosts lookup in an ACL, its value
3394 could be overwritten at the end of the current message (or the start of a
3395 new message if it was set in a HELO ACL). The value is now preserved for
3396 the duration of the SMTP connection.
3397
339812. If a transport had a headers_rewrite setting, and a matching header line
3399 contained an unqualified address, that address was qualified, even if it
3400 did not match any rewriting rules. The underlying bug was that the values
3401 of the flags that permit the existence of unqualified sender and recipient
3402 addresses in header lines (set by {sender,recipient}_unqualified_hosts for
3403 non-local messages, and by -bnq for local messages) were not being
3404 preserved with the message after it was received.
3405
340613. When Exim was logging an SMTP synchronization error, it could sometimes log
3407 "next input=" as part of the text comprising the host identity instead of
3408 the correct text. The code was using the same buffer for two different
3409 strings. However, depending on which order the printing function evaluated
3410 its arguments, the bug did not always show up. Under Linux, for example, my
3411 test suite worked just fine.
3412
341314. Exigrep contained a use of Perl's "our" scoping after change 4.31/70. This
3414 doesn't work with some older versions of Perl. It has been changed to "my",
3415 which in any case is probably the better facility to use.
3416
341715. A really picky compiler found some instances of statements for creating
3418 error messages that either had too many or two few arguments for the format
3419 string.
3420
342116. The size of the buffer for calls to the DNS resolver has been increased
3422 from 1024 to 2048. A larger buffer is needed when performing PTR lookups
3423 for addresses that have a lot of PTR records. This alleviates a problem; it
3424 does not fully solve it.
3425
342617. A dnsdb lookup for PTR records that receives more data than will fit in the
3427 buffer now truncates the list and logs the incident, which is the same
3428 action as happens when Exim is looking up a host name and its aliases.
3429 Previously in this situation something unpredictable would happen;
3430 sometimes it was "internal error: store_reset failed".
3431
343218. If a server dropped the connection unexpectedly when an Exim client was
3433 using GnuTLS and trying to read a response, the client delivery process
3434 crashed while trying to generate an error log message.
3435
343619. If a "warn" verb in an ACL added multiple headers to a message in a single
3437 string, for example:
3438
3439 warn message = H1: something\nH2: something
3440
3441 the text was added as a single header line from Exim's point of view
3442 though it ended up OK in the delivered message. However, searching for the
3443 second and subsequent header lines using $h_h2: did not work. This has been
3444 fixed. Similarly, if a system filter added multiple headers in this way,
3445 the routers could not see them.
3446
344720. Expanded the error message when iplsearch is called with an invalid key to
3448 suggest using net-iplsearch in a host list.
3449
345021. When running tests using -bh, any delays imposed by "delay" modifiers in
3451 ACLs are no longer actually imposed (and a message to that effect is
3452 output).
3453
345422. If a "gecos" field in a passwd entry contained escaped characters, in
3455 particular, if it contained a \" sequence, Exim got it wrong when building
3456 a From: or a Sender: header from that name. A second bug also caused
3457 incorrect handling when an unquoted " was present following a character
3458 that needed quoting.
3459
346023. "{crypt}" as a password encryption mechanism for a "crypteq" expansion item
3461 was not being matched caselessly.
3462
346324. Arranged for all hyphens in the exim.8 source to be escaped with
3464 backslashes.
3465
346625. Change 16 of 4.32, which reversed 71 or 4.31 didn't quite do the job
3467 properly. Recipient callout cache records were still being keyed to include
3468 the sender, even when use_sender was set false. This led to far more
3469 callouts that were necessary. The sender is no longer included in the key
3470 when use_sender is false.
3471
347226. Added "control = submission" modifier to ACLs.
3473
347427. Added the ${base62d: operator to decode base 62 numbers.
3475
347628. dnsdb lookups can now access SRV records.
3477
347829. CONFIGURE_OWNER can be set at build time to define an alternative owner for
3479 the configuration file.
3480
348130. The debug message "delivering xxxxxx-xxxxxx-xx" is now output in verbose
3482 (-v) mode. This makes the output for a verbose queue run more intelligible.
3483
348431. Added a use_postmaster feature to recipient callouts.
3485
348632. Added the $body_zerocount variable, containing the number of binary zero
3487 bytes in the message body.
3488
348933. The time of last modification of the "new" subdirectory is now used as the
3490 "mailbox time last read" when there is a quota error for a maildir
3491 delivery.
3492
349334. Added string comparison operators lt, lti, le, lei, gt, gti, ge, gei.
3494
349535. Added +ignore_unknown as a special item in host lists.
3496
349736. Code for decoding IPv6 addresses in host lists is now included, even if
3498 IPv6 support is not being compiled. This fixes a bug in which an IPv6
3499 address was recognized as an IP address, but was then not correctly decoded
3500 into binary, causing unexpected and incorrect effects when compared with
