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

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

338PH/18 If a system quota error occurred while trying to create the file for
339 a maildir delivery, the message "Mailbox is full" was not appended to the

341 only to a quota excession during the actual writing of the file.
d6a60c0f 342
ddea74fa 343PH/19 It seems that peer DN values may contain newlines (and other non-printing

345 passed through string_printing() before being added to log lines.

PH
371PH/02 In an ACL statement such as
372
373 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
374
375 if a client was not listed at all, or was listed with a value other than
376 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
377 the condition was not true (as it should be), so access was not denied.
378 The bug was that the ! inversion was incorrectly passed on to the second
379 item. This has been fixed.
380
381PH/03 Added additional dnslists conditions == and =& which are different from
382 = and & when the dns lookup returns more than one IP address.
383
83da1223

PH
387PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_

396 including adding "make clean"; (3) Added -fPIC when compiling the test
397 dynamically loaded module, to get rid of a warning.

PH
481PH/29 SMTP synchronization checks are implemented when a command is read -
482 there is a check that no more input is waiting when there shouldn't be
483 any. However, for some commands, a delay in an ACL can mean that it is
484 some time before the response is written. In this time, more input might
485 arrive, invalidly. So now there are extra checks after an ACL has run for
486 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
487 pipelining has not been advertised.

502 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
503 was a macro that became an assignment, so it seemed to work. This has

533PH/40 When Exim receives a message, it writes the login name, uid, and gid of

536 started the daemon, but after a SIGHUP it used the Exim user (because it
537 calls itself on a restart). I have changed the code so that it now always
538 uses the Exim user.

PH
561 the response to the final '.' that terminates a message, but only in the
562 case where the client has not sent further data following the '.'
563 (unfortunately, this is allowed). However, in many cases there won't be
564 any further data because there won't be any more messages to send. A call
565 to select() can be used: if it shows that the input is "ready", there is
566 either input waiting, or the socket has been closed. An attempt to read
567 the next input character can distinguish the two cases. Previously, Exim
58eb016e 568 would have sent an OK response which the client would never have see.

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

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

618TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
619 leftover -K file (the existence of which was triggered by #402).
620 While we were at it, introduced process PID as part of the -K

627

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

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

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

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

717PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
718 look up a TXT record in a specific list after matching in a combined
719 list.
720
322050c2
PH
721PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
722 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
723 they consult the DNS. I had assumed they would set it the way they
724 wanted; and indeed my experiments on Linux seem to show that in some
725 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
726 To be on the safe side, however, I have now made the interface to
727 host_find_byname() similar to host_find_bydns(), with an argument
728 containing the DNS resolver options. The host_find_byname() function now
729 sets these options at its start, just as host_find_bydns() does. The smtp
730 transport options dns_qualify_single and dns_search_parents are passed to
731 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
732 of host_find_byname() use the default settings of RES_DEFNAMES
733 (qualify_single) but not RES_DNSRCH (search_parents).
734
08955dd3
PH
735PH/17 Applied (a modified version of) Nico Erfurth's patch to make
736 spool_read_header() do less string testing, by means of a preliminary
737 switch on the second character of optional "-foo" lines. (This is
738 overdue, caused by the large number of possibilities that now exist.
739 Originally there were few.) While I was there, I also converted the
740 str(n)cmp tests so they don't re-test the leading "-" and the first
741 character, in the hope this might squeeze out yet more improvement.

PH
743PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
744 flag allowing group syntax was set by the header_syntax check but not
745 turned off, possible causing trouble later; (2) The flag was not being
746 set at all for the header_verify test, causing "group"-style headers to
747 be rejected. I have now set it in this case, and also caused header_
748 verify to ignore an empty address taken from a group. While doing this, I
749 came across some other cases where the code for allowing group syntax
750 while scanning a header line wasn't quite right (mostly, not resetting
751 the flag correctly in the right place). These bugs could have caused
752 trouble for malformed header lines. I hope it is now all correct.
753
602e59e5
PH
754PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
755 with the "reply" argument non-NULL. The code, however (which originally
756 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
757 but it didn't always do it. This confused somebody who was copying the
758 code for some other use. I have removed all the tests.

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

7befa435
PH
768PH/21 On the advice of Timo Sirainen, added a check to the dovecot
769 authenticator to fail if there's a tab character in the incoming data
770 (there should never be unless someone is messing about, as it's supposed
771 to be base64-encoded). Also added, on Timo's advice, the "secured" option
772 if the connection is using TLS or if the remote IP is the same as the
773 local IP, and the "valid-client-cert option" if a client certificate has
774 been verified.

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

843PH/35 The error "getsockname() failed: connection reset by peer" was being
844 written to the panic log as well as the main log, but it isn't really

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

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

1130 kind of temporary error. A kludge has been added to help with this.
1131 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1132 554 error is used if errno is still zero or contains ENOENT (which occurs

1216PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
1217 syntactically invalid From: or Reply-to: line, and a filter used this to
1218 generate an autoreply, and therefore failed to obtain an address for the
1219 autoreply, Exim could try to deliver to a non-existent relative file
1220 name, causing unrelated and misleading errors. What now happens is that
1221 it logs this as a hard delivery error, but does not attempt to create a
1222 bounce message.

1234 literals of the form [IPV4:n.n.n.n] are now always recognized.

1236PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
1237 used if the router is not running as root, for example, when verifying at
1238 ACL time, or when using -bh. The debugging output from this situation was
1239 non-existent - all you got was a failure to exec. I have made two
1240 changes:
1241
1242 (a) Failures to set uid/gid, the current directory, or a process leader
1243 in a subprocess such as that created by queryprogram now generate
1244 suitable debugging ouput when -d is set.
1245
1246 (b) The queryprogram router detects when it is not running as root,
1247 outputs suitable debugging information if -d is set, and then runs
1248 the subprocess without attempting to change uid/gid.

PH
1253PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1254 additional section of a DNS packet that returns MX or SRV records.
1255 Instead, it always explicitly searches for A/AAAA records. This avoids
1256 major problems that occur when a DNS server includes only records of one
1257 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1258 fixed another bug: if SRV records were looked up and the corresponding
1259 address records were *not* found in the additional section, the port
1260 values from the SRV records were lost.

1262PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1266PH/18 If quota_warn_message contains a From: header, Exim now refrains from

1268 errors_reply_to option, if set, is not used.
1269
727071f8
PH
1270PH/19 When calculating a retry time, Exim used to measure the "time since
1271 failure" by looking at the "first failed" field in the retry record. Now
1272 it does not use this if it is later than than the arrival time of the
1273 message. Instead it uses the arrival time. This makes for better
1274 behaviour in cases where some deliveries succeed, thus re-setting the
1275 "first failed" field. An example is a quota failure for a huge message
1276 when small messages continue to be delivered. Without this change, the
1277 "time since failure" will always be short, possible causing more frequent
1278 delivery attempts for the huge message than are intended.

PH
1375PH/42 The content-scanning code uses fopen() to create files in which to put
1376 message data. Previously it was not paying any attention to the mode of
1377 the files. Exim runs with umask(0) because the rest of the code creates
1378 files with open(), and sets the required mode explicitly. Thus, these
1379 files were ending up world-writeable. This was not a big issue, because,
1380 being within the spool directory, they were not world-accessible. I have
1381 created a function called modefopen, which takes an additional mode
1382 argument. It sets umask(777), creates the file, chmods it to the required
1383 mode, then resets the umask. All the relevant calls to fopen() in the
1384 content scanning code have been changed to use this function.

1395 received. Setting client_ignore_invalid_base64 true ignores these errors.
1396 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1397 they are received. Thus, the responses can be made to depend on the

1419PH/52 Two bugs concerned with error handling when the smtp transport is
1420 used in LMTP mode:
1421
1422 (i) Exim was not creating retry information for temporary errors given
1423 for individual recipients after the DATA command when the smtp transport
1424 was used in LMTP mode. This meant that they could be retried too
1425 frequently, and not timed out correctly.
1426
1427 (ii) Exim was setting the flag that allows error details to be returned
1428 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1429 recipients that were returned after the DATA command.
1430
1431PH/53 This is related to PH/52, but is more general: for any failing address,
1432 when detailed error information was permitted to be returned to the
1433 sender, but the error was temporary, then after the final timeout, only
1434 "retry timeout exceeded" was returned. Now it returns the full error as

1505PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1506 function verify_get_ident() calls ip_connect() to connect a socket, but
1507 if the "connect()" function timed out, ip_connect() used to close the
1508 socket. However, verify_get_ident() also closes the socket later, and in
1509 between Exim writes to the log, which may get opened at this point. When
1510 the socket was closed in ip_connect(), the log could get the same file
1511 descriptor number as the socket. This naturally causes chaos. The fix is
1512 not to close the socket in ip_connect(); the socket should be closed by
1513 the function that creates it. There was only one place in the code where
1514 this was missing, in the iplookup router, which I don't think anybody now
1515 uses, but I've fixed it anyway.

1542 (3) Reset the variables that are obtained from the first argument of
1543 ${prvscheck and used in the second argument before leaving the code,
1544 because their memory is reclaimed, so using them afterwards may do
1545 silly things.

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

1581 doesn't show the same IP address twice.

1609
1610 Auto-submitted: auto-generated
1611
1612 in the messages that it generates (bounce messages and others, such as
1613 warnings). In the case of bounce messages for non-SMTP mesages, there was
1614 also a typo: it was using "Auto_submitted" (underscore instead of
1615 hyphen). Since every message generated by Exim is necessarily in response
1616 to another message, thes have all been changed to:
1617
1618 Auto-Submitted: auto-replied
1619
1620 in accordance with these statements in the RFC:
1621
1622 The auto-replied keyword:
1623
1624 - SHOULD be used on messages sent in direct response to another
1625 message by an automatic process,
1626
1627 - MUST NOT be used on manually-generated messages,
1628
1629 - MAY be used on Delivery Status Notifications (DSNs) and Message
1630 Disposition Notifications (MDNs),
1631
1632 - MUST NOT be used on messages generated by automatic or periodic
1633 processes, except for messages which are automatic responses to
1634 other messages.

1655PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
1656 extension "envelope-auth". The code is finished and in agreement with
1657 other implementations, but there is no documentation so far and in fact,
1658 nobody wrote the draft yet. This extension is currently #undef'ed, thus
1659 not changing the active code.

1661 Print executed "if" and "elsif" statements when debugging is used. This
1662 helps a great deal to understand what a filter does.

PH
1670PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1671 canonical form (as documented). However, after a host name lookup from
1672 the IP address, check_host() was doing a simple string comparison with
1673 addresses acquired from the DNS when checking that the found name did
1674 have the original IP as one of its addresses. Since any found IPv6
1675 addresses are likely to be in abbreviated form, the comparison could
1676 fail. Luckily, there already exists a function for doing the comparison
1677 by converting both addresses to binary, so now that is used instead of
1678 the text comparison.
1679
96776534
PH
1680PH/20 There was another similar case to PH/19, when a complete host name was
1681 given in a host list; looking up its IP address could give an abbreviated
1682 form, whereas the current host's name might or might not be abbreviated.
1683 The same fix has been applied.

1977 Fortunately, Exim does not actually use EX_OK. The code used to try to
1978 preserve the sysexits.h value, by assumimg that macro definitions were
1979 scanned for macro replacements. I have been disabused of this notion,

2012TK/06 MBOX spool code: Add real "From " MBOX separator line
2013 so the .eml file is really in mbox format (even though
2014 most programs do not really care). Patch from Alex Miller.
2015
2016TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
2017 The latter is generated from $received_to and is only set if the

2019 obviously out-of-the-box. Patch from Alex Miller.

2060PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2061 the configuration file to be ":syslog", then the script "guesses" where
2062 the logs files are, rather than using the compiled in default. In our
2063 case the guess is not the same as the compiled default, so the script
2064 suddenly stopped working when I started to use syslog. The patch checks
2065 to see if log_file_path is "". If so, it attempts to read it from exim
2066 with no configuration file to get the compiled in version, before it
2067 falls back to the previous guessing code."

2117 picked up on a user's system that detects such things. There doesn't seem
2118 to be a gcc warning option for this - only an attribute that has to be
2119 put on the function's prototype. It seems that in Fedora Core 4 they have

PH
2123PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2124 specify a transport. However, if an address that was verified by such a
2125 router was the subject of a callout, Exim crashed because it tried to
2126 read the rcpt_include_affixes from the non-existent transport. Now it
2127 just assumes that the setting of that option is false. This bug was
2128 introduced by 4.51/PH/31.

2138PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2139 aren't the modern standard, and it seems that some systems' include files

2141 ones like T_AAAA, and defining it itself. I've added checks for all the
2142 record types that Exim uses.

PH
2144PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was

2147 data, a new version was generated, as expected. It was only the case of a
2148 non-existent file that was broken.

2195
2196PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2197 that changes the way the GnuTLS parameters are stored in the cache file.
2198 The new format can be generated externally. For backward compatibility,
2199 if the data in the cache doesn't make sense, Exim assumes it has read an
2200 old-format file, and it generates new data and writes a new file. This
2201 means that you can't go back to an older release without removing the
2202 file.
2203
2204PH/03 A redirect router that has both "unseen" and "one_time" set does not
2205 work if there are any delivery delays because "one_time" forces the
2206 parent to be marked "delivered", so its unseen clone is never tried
2207 again. For this reason, Exim now forbids the simultaneous setting of
2208 these two options.
2209
2210PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2211 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2212 entry if you want to know the details. The fix, however, neglected to
2213 consider the case when local delivery batching is involved. The test for
2214 "previously delivered" was not happening when checking to see if an
2215 address could be batched with a previous (undelivered) one; under
2216 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2217 address.

PH
2218
2219PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2220 in its include files, and this causes problems building Exim.
2221
2222PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2223 header_syntax) but Exim was just ignoring anything given after a slash.
2224 In particular, this caused confusion with an attempt to use "verify =
2225 reverse_host_lookup/defer_ok". An error is now given when options are
2226 supplied for verify items that do not have them. (Maybe reverse_host_
2227 lookup should have a defer_ok option, but that's a different point.)
2228
2229PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2230 defined by RFC 821) to 2048, because there were problems with some AUTH

PH
2279PH/19 When an Exim process that is running as root has to create an Exim log
2280 file, it does so in a subprocess that runs as exim:exim so as to get the
2281 ownership right at creation (otherwise, other Exim processes might see
2282 the file with the wrong ownership). There was no test for failure of this
2283 fork() call, which would lead to the process getting stuck as it waited
2284 for a non-existent subprocess. Forks do occasionally fail when resources
2285 run out. I reviewed all the other calls to fork(); they all seem to check
2286 for failure.

PH
2288PH/20 When checking for unexpected SMTP input at connect time (before writing
2289 the banner), Exim was not dealing correctly with a non-positive return
2290 from the read() function. If the client had disconnected by this time,
2291 the result was a log entry for a synchronization error with an empty
2292 string after "input=" when read() returned zero. If read() returned -1
2293 (an event I could not check), uninitialized data bytes were printed.

c5ddb310
PH
2305PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2306 hadn't been configured. The fix is from Juergen Kreileder, who
2307 understands it better than I do:
2308
2309 "Here's what I see happening with three configured cyrus_sasl
2310 authenticators configured (plain, login, cram-md5):
2311
2312 On startup auth_cyrus_sasl_init() gets called for each of these.
2313 This means three calls to sasl_listmech() without a specified mech_list.
2314 => SASL tests which mechs of all available mechs actually work
2315 => three warnings about OTP not working
2316 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2317
2318 With the patch, sasl_listmech() also gets called three times. But now
2319 SASL's mech_list option is set to the server_mech specified in the the
2320 authenticator. Or in other words, the answer from sasl_listmech()
2321 gets limited to just the mech you're testing for (which is different
2322 for each call.)
2323 => the return list contains just 'plain' or 'login', 'cram-md5' or
2324 nothing depending on the value of ob->server_mech.
2325
2326 I've just tested the patch: Authentication still works fine,
2327 unavailable mechs specified in the exim configuration are still
2328 caught, and the auth.log warnings about OTP are gone."

PH
2392PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2393 the grounds that routing the same address twice would always produce the
2394 same answer. This might have been true once, but it is certainly no
2395 longer true now. Routing a child address may depend on the previous
2396 routing that produced that child. Some complicated redirection strategies
2397 went wrong when messages had multiple recipients, and made Exim's
2398 behaviour dependent on the order in which the addresses were given.
2399
2400 I have moved the duplicate checking until after the routing is complete.
2401 Exim scans the addresses that are assigned to local and remote
2402 transports, and removes any duplicates. This means that more work will be
2403 done, as duplicates will always all be routed, but duplicates are
2404 presumably rare, so I don't expect this is of any significance.
2405
2406 For deliveries to pipes, files, and autoreplies, the duplicate checking
2407 still happens during the routing process, since they are not going to be
2408 routed further.

2410PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
2411 It corrects a timeout issue with spamd. This is Ian's comment: "The
2412 background is that sometimes spamd either never reads data from a
2413 connection it has accepted, or it never writes response data. The exiscan
2414 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2415 blindly assumes that writes won't block so it may never time out."

2429PH/42 Exim no longer gives details of delivery errors for specific addresses in
2430 bounce and delay warning messages, except in certain special cases, which
2431 are as follows:
2432
2433 (a) An SMTP error message from a remote host;
2434 (b) A message specified in a :fail: redirection;
2435 (c) A message specified in a "fail" command in a system filter;
2436 (d) A message specified in a FAIL return from the queryprogram router;
2437 (e) A message specified by the cannot_route_message router option.
2438
2439 In these cases only, Exim does include the error details in bounce and
2440 warning messages. There are also a few cases where bland messages such
2441 as "unrouteable address" or "local delivery error" are given.

2449PH/45 In a pipe transport, although a timeout while waiting for the pipe
2450 process to complete was treated as a delivery failure, a timeout while
2451 writing the message to the pipe was logged, but erroneously treated as a
2452 successful delivery. Such timeouts include transport filter timeouts. For
2453 consistency with the overall process timeout, these timeouts are now
2454 treated as errors, giving rise to delivery failures by default. However,
2455 there is now a new Boolean option for the pipe transport called
2456 timeout_defer, which, if set TRUE, converts the failures into defers for
2457 both kinds of timeout. A transport filter timeout is now identified in
2458 the log output.

2467A note about Exim versions 4.44 and 4.50
2468----------------------------------------
2469
2470Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2471changes of various kinds. As a consequence, a big documentation update was
2472needed. This delayed the release for rather longer than seemed good, especially
2473in the light of a couple of (minor) security issues. Therefore, the changes
2474that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2475release. So 4.44 and 4.50 are in effect two different branches that both start
2476from 4.43.
2477
2478I have left the 4.50 change log unchanged; it contains all the changes since
24794.43. The change log for 4.44 is below; many of its items are identical to
2480those for 4.50. This seems to be the most sensible way to preserve the
2481historical information.

2487 1. Minor wording change to the doc/README.SIEVE file.
2488
139059f6 2489 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the

2492 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The

2494 place.

PH
2499 5. There are several places where Exim runs a non-Exim command in a
2500 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2501 was being done only for the command run by the queryprogram router. It is
2502 now done for all such subprocesses. The other cases are: ${run, transport
2503 filters, and the commands run by the lmtp and pipe transports.

PH
2505 6. Added CONFIGURE_GROUP build-time option.
2506
2507 7. Some older OS have a limit of 256 on the maximum number of file
2508 descriptors. Exim was using setrlimit() to set 1000 as a large value
2509 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2510 systems. I've change it so that if it can't get 1000, it tries for 256.

2512 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2513 was an oversight, and furthermore, ever since the addition of extra
2514 controls (e.g. 4.43/32), the checks on when to allow different forms of
2515 "control" were broken. There should now be diagnostics for all cases when a
2516 control that does not make sense is encountered.

252712. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2528 of $address_data from the recipient verification was clobbered by the
2529 sender verification.

2532 $sender_address_data in subsequent conditions in the ACL statement.

PH
255722. $host_address is now set to the target address during the checking of
2558 ignore_target_hosts.
2559
256023. When checking ignore_target_hosts for an ipliteral router, no host name was
2561 being passed; this would have caused $sender_host_name to have been used if
2562 matching the list had actually called for a host name (not very likely,
2563 since this list is usually IP addresses). A host name is now passed as
2564 "[x.x.x.x]".
2565
7d468ab8
PH
256624. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2567 code that specifies a non-restarting handler (typically sigaction() in
2568 modern systems) in an attempt to fix a rare and obscure crash bug.
2569
257025. Narrowed the window for a race in the daemon that could cause it to ignore
2571 SIGCHLD signals. This is not a major problem, because they are used only to
2572 wake it up if nothing else does.
2573
62c0818f
PH
257426. A malformed maildirsize file could cause Exim to calculate negative values
2575 for the mailbox size or file count. Odd effects could occur as a result.
2576 The maildirsize information is now recalculated if the size or filecount
2577 end up negative.
2578
26034054
PH
257927. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this

258228. Installed the latest version of exipick from John Jetmore.
2583
90af77f4
PH
258429. In an address list, if the pattern was not a regular expression, an empty
2585 subject address (from a bounce message) matched only if the pattern was an
2586 empty string. Non-empty patterns were not even tested. This was the wrong
2587 because it is perfectly reasonable to use an empty address as part of a
2588 database query. An empty address is now tested by patterns that are
2589 lookups. However, all the other forms of pattern expect the subject to
2590 contain a local part and a domain, and therefore, for them, an empty
2591 address still always fails if the pattern is not itself empty.
2592
d8ef3577
PH
259330. Exim went into a mad DNS loop when attempting to do a callout where the
2594 host was specified on an smtp transport, and looking it up yielded more
2595 than one IP address.
2596
5cb8cbc6
PH
259731. Re-factored the code for checking spool and log partition space into a
2598 function that finds that data and another that does the check. The former
2599 is then used to implement four new variables: $spool_space, $log_space,
2600 $spool_inodes, and $log_inodes.
2601
14702f5b
PH
260232. The RFC2047 encoding function was originally intended for short strings
2603 such as real names; it was not keeping to the 75-character limit for
2604 encoded words that the RFC imposes. It now respects the limit, and
2605 generates multiple encoded words if necessary. To be on the safe side, I
2606 have increased the buffer size for the ${rfc2047: expansion operator from
2607 1024 to 2048 bytes.
2608
063b1e99
PH
260933. It is now permitted to omit both strings after an "if" condition; if the
2610 condition is true, the result is "true". As before, when the second string
2611 is omitted, a false condition yields an empty string. This makes it less
2612 cumbersome to write custom ACL and router conditions.
2613
652e1b65
PH
261434. Failure to deliver a bounce message always caused it to be frozen, even if
2615 there was an errors_to setting on the router. The errors_to setting is now
2616 respected.
2617
6f0c9a4f
PH
261835. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2619 canonical form (fully expanded) before being placed in
2620 $sender_host_address.
2621
33397d19
PH
262236. The table in the code that translates DNS record types into text (T_A to
2623 "A" for instance) was missing entries for NS and CNAME. It is just possible
2624 that this could have caused confusion if both these types were looked up
2625 for the same domain, because the text type is used as part of Exim's
2626 per-process caching. But the chance of anyone hitting this buglet seems
2627 very small.
2628
7bb56e1f
PH
262937. The dnsdb lookup has been extended in a number of ways.
2630
2631 (1) There is a new type, "zns", which walks up the domain tree until it
2632 finds some nameserver records. It should be used with care.
2633
ea3bc19b
PH
2634 (2) There is a new type, "mxh", which is like "mx" except that it returns
2635 just the host names, not the priorities.
2636
2637 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2638 looked up. The behaviour when one of the lookups defers can be
2639 controlled by a keyword.
7bb56e1f 2640
ea3bc19b 2641 (4) It is now possible to specify the separator character for use when
7bb56e1f 2642 multiple records are returned.
33397d19 2643
0bcb2a0e
PH
264438. The dnslists ACL condition has been extended: it is now possible to supply
2645 a list of IP addresses and/or domains to be looked up in a particular DNS
2646 domain.

PH
264839. Added log_selector=+queue_time_overall.

265040. When running the queue in the test harness, wait just a tad after forking a
2651 delivery process, to get repeatability of debugging output.

PH
265341. Include certificate and key file names in error message when GnuTLS fails

2655 of the failing file when there is a problem reading it.

2662
266345. Sometimes the final signoff response after QUIT could fail to get
2664 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2665 < 0 before doing a fflush(). This bug looks as though it goes back to the
2666 introduction of TLS in release 3.20, but "sometimes" must have been rare
2667 because the tests only now provoked it.

PH
267247. exim_tidydb, when checking for the continued existence of a message for

2674 messages that were in split spool directories. Consequently, it was
2675 deleting retry records that should have stayed in existence.

2680 on to the next authenticator when an expansion was forced to fail,
2681 contradicting the general specification for all authenticators. Instead it
2682 was generating a temporary error. It now behaves as specified.
2683

PH
268450. The default ordering of permitted cipher suites for GnuTLS was pessimal
2685 (the order specifies the preference for clients). The order is now AES256,

268851. Small patch to Sieve code - explicitly set From: when generating an

PH
269152. Exim crashed if a remote delivery caused a very long error message to be
2692 recorded - for instance if somebody sent an entire SpamAssassin report back
2693 as a large number of 550 error lines. This bug was coincidentally fixed by
2694 increasing the size of one of Exim's internal buffers (big_buffer) that
2695 happened as part of the Exiscan merge. However, to be on the safe side, I
2696 have made the code more robust (and fixed the comments that describe what
2697 is going on).
2698
55ee9ee3
PH
269953. Now that there can be additional text after "Completed" in log lines (if
2700 the queue_time_overall log selector is set), a one-byte patch to exigrep

2702 the line.
2703

PH
270454. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2705 patch that reportedly fixes this has been added. I am not expert enough to
2706 create a test for it. This is what the patch creator wrote:
2707
2708 "I found a little strange behaviour of ldap code when working with
2709 Windows 2003 AD Domain, where users was placed in more than one
2710 Organization Units. When I tried to give exim partial DN, the exit code
2711 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2712 But simultaneously result of request was absolutely normal ldap result,
2713 so I produce this patch..."
2714
3295e65b
PH
2715 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2716 REFERENCE, so I have modified the code to exclude the patch when that macro
2717 is not defined.
2718

PH
271955. Some experimental protocols are using DNS PTR records for new purposes. The
2720 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2721 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2722 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
273058. The exicyclog utility now does better if the number of log files to keep

PH
273359. Two changes related to the smtp_active_hostname option:
2734
2735 (1) $smtp_active_hostname is now available as a variable.
2736 (2) The default for smtp_banner uses $smtp_active_hostname instead
2737 of $primary_hostname.
2738
b975ba52
PH
273960. The host_aton() function is supposed to be passed a string that is known
2740 to be a valid IP address. However, in the case of IPv6 addresses, it was
2741 not checking this. This is a hostage to fortune. Exim now panics and dies
2742 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2743 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2744 components; fortuitously, this particular loophole had already been fixed
2745 by change 4.50/55 above.
2746
2747 If there are any other similar loopholes, the new check in host_aton()
2748 itself should stop them being exploited. The report I received stated that
2749 data on the command line could provoke the exploit when Exim was running as
2750 exim, but did not say which command line option was involved. All I could
2751 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2752 running as the user.

PH
276363. The daemon start-up calls getloadavg() while still root for those OS that
2764 need the first call to be done as root, but it missed one case: when
2765 deliver_queue_load_max is set with deliver_drop_privilege. This is
2766 necessary for the benefit of the queue runner, because there is no re-exec
2767 when deliver_drop_privilege is set.

PH
276964. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
2770 This has been fixed.
2771
60dc5e56
PH
277265. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2773 was in use, was not putting the data itself into the right store pool;
2774 consequently, it could be overwritten for a subsequent message in the same
2775 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2776 the caching.)

PH
277866. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
278067. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2781 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2782 the function were treating the return as a boolean value, which happened to
2783 work because 0=false and not-0=true, but is not correct code.
2784
7e634d24
PH
278568. The host_aton() function was not handling scoped IPv6 addresses (those
2786 with, for example, "%eth0" on the end) correctly.

PH
278869. Fixed some compiler warnings in acl.c for the bitmaps specified with
2789 negated items (that is, ~something) in unsigned ints. Some compilers
2790 apparently mutter when there is no cast.
2791
6729cf78
PH
279270. If an address verification called from an ACL failed, and did not produce a
2793 user-specific message (i.e. there was only a "system" message), nothing was
2794 put in $acl_verify_message. In this situation, it now puts the system
2795 message there.
2796
00f00ca5
PH
279771. Change 4.23/11 added synchronization checking at the start of an SMTP
2798 session; change 4.31/43 added the unwanted input to the log line - except
2799 that it did not do this in the start of session case. It now does.
2800
c9bdd01c
PH
280172. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2802 This is wrong and can cause the other end to generate a synchronization
2803 error if it is another Exim or anything else that does the synchronization
2804 check. A QUIT command is no longer sent after a timeout.
2805
d43194df
PH
280673. $host_lookup_deferred has been added, to make it easier to detect DEFERs
2807 during host lookups.
2808
fe5b5d0b
PH
280974. The defer_ok option of callout verification was not working if it was used
2810 when verifying addresses in header lines, that is, for this case:
2811
2812 verify = header_sender/callout=defer_ok
2813
76a2d7ba
PH
281475. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2815 those file descriptors could be used for SMTP connections. If anything
2816 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2817 could be sent to the SMTP client, causing chaos. The daemon now opens
2818 stdin, stdout, and stderr to /dev/null when it puts itself into the
2819 background.
2820
282176. Arrange for output from Perl's "warn" command to be written to Exim's main
2822 log by default. The user can override this with suitable Perl magic.
2823
04f7d5b9
PH
282477. The use of log_message on a "discard" ACL verb, which is supposed to add to
2825 the log message when discard triggers, was not working for the DATA ACL or
2826 for the non-SMTP ACL.
2827
bc60667e
PH
282878. Error message wording change in sieve.c.
2829
bb6e88ff
PH
283079. If smtp_accept_max_per_host was set, the number of connections could be
2831 restricted to fewer than expected, because the daemon was trying to set up
2832 a new connection before checking whether the processes handling previous
2833 connections had finished. The check for completed processes is now done
2834 earlier. On busy systems, this bug wouldn't be noticed because something
2835 else would have woken the daemon, and it would have reaped the completed
2836 process earlier.
2837
1e70f85b
PH
283880. If a message was submitted locally by a user whose login name contained one
2839 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2840 It caused a spool format error. I have fixed the spool reading code. A
2841 related problem was that the "from" clause in the Received: line became
2842 illegal because of the space(s). It is now covered by ${quote_local_part.
2843
284481. Included the latest eximstats from Steve (adds average sizes to HTML Top
2845 tables).
2846
4e01f9d6
PH
284782. Updated OS/Makefile-AIX as per message from Mike Meredith.

284983. Patch from Sieve maintainer to fix unterminated string problem in
2850 "vacation" handling.

285284. Some minor changes to the Linux configuration files to help with other
2853 OS variants using glibc.

2858----------------------------------------------------
2859See the note above about the 4.44 and 4.50 releases.
2860----------------------------------------------------
2861
2862
2863Exim version 4.44
2864-----------------
2865
2866 1. Change 4.43/35 introduced a bug that caused file counts to be
2867 incorrectly computed when quota_filecount was set in an appendfile
2868 transport
2869
2870 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2871 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2872 place.
2873
2874 3. Give more explanation in the error message when the command for a transport
2875 filter fails to execute.
2876
2877 4. There are several places where Exim runs a non-Exim command in a
2878 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2879 was being done only for the command run by the queryprogram router. It is
2880 now done for all such subprocesses. The other cases are: ${run, transport
2881 filters, and the commands run by the lmtp and pipe transports.
2882
2883 5. Some older OS have a limit of 256 on the maximum number of file
2884 descriptors. Exim was using setrlimit() to set 1000 as a large value
2885 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2886 systems. I've change it so that if it can't get 1000, it tries for 256.
2887
2888 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2889 was an oversight, and furthermore, ever since the addition of extra
2890 controls (e.g. 4.43/32), the checks on when to allow different forms of
2891 "control" were broken. There should now be diagnostics for all cases when a
2892 control that does not make sense is encountered.
2893
2894 7. $recipients is now available in the predata ACL (oversight).
2895
2896 8. Tidy the search cache before the fork to do a delivery from a message
2897 received from the command line. Otherwise the child will trigger a lookup
2898 failure and thereby defer the delivery if it tries to use (for example) a
2899 cached ldap connection that the parent has called unbind on.
2900
2901 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2902 of $address_data from the recipient verification was clobbered by the
2903 sender verification.
2904
290510. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
2906 was its contents. (It was OK if the option was not defined at all.)
2907
290811. A "Completed" log line is now written for messages that are removed from
2909 the spool by the -Mrm option.
2910
291112. $host_address is now set to the target address during the checking of
2912 ignore_target_hosts.
2913
291413. When checking ignore_target_hosts for an ipliteral router, no host name was
2915 being passed; this would have caused $sender_host_name to have been used if
2916 matching the list had actually called for a host name (not very likely,
2917 since this list is usually IP addresses). A host name is now passed as
2918 "[x.x.x.x]".
2919
292014. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2921 code that specifies a non-restarting handler (typically sigaction() in
2922 modern systems) in an attempt to fix a rare and obscure crash bug.
2923
292415. Narrowed the window for a race in the daemon that could cause it to ignore
2925 SIGCHLD signals. This is not a major problem, because they are used only to
2926 wake it up if nothing else does.
2927
292816. A malformed maildirsize file could cause Exim to calculate negative values
2929 for the mailbox size or file count. Odd effects could occur as a result.
2930 The maildirsize information is now recalculated if the size or filecount
2931 end up negative.
2932
293317. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2934 support for a long time. Removed HAVE_SYS_VFS_H.
2935
ea3a6f44 293618. Updated exipick to current release from John Jetmore.
bbe902f0
PH
2937
293819. Allow an empty sender to be matched against a lookup in an address list.
2939 Previously the only cases considered were a regular expression, or an
2940 empty pattern.
2941
294220. Exim went into a mad DNS lookup loop when doing a callout where the
2943 host was specified on the transport, if the DNS lookup yielded more than
2944 one IP address.
2945
ea3a6f44
NM
294621. The RFC2047 encoding function was originally intended for short strings
2947 such as real names; it was not keeping to the 75-character limit for
2948 encoded words that the RFC imposes. It now respects the limit, and
2949 generates multiple encoded words if necessary. To be on the safe side, I
2950 have increased the buffer size for the ${rfc2047: expansion operator from
2951 1024 to 2048 bytes.
bbe902f0 2952
ea3a6f44
NM
295322. Failure to deliver a bounce message always caused it to be frozen, even if
2954 there was an errors_to setting on the router. The errors_to setting is now
2955 respected.
bbe902f0
PH
2956
295723. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2958 canonical form (fully expanded) before being placed in
2959 $sender_host_address.
2960
296124. Updated eximstats to version 1.33
2962
ea3a6f44
NM
296325. Include certificate and key file names in error message when GnuTLS fails
2964 to set them up, because the GnuTLS error message doesn't include the name
2965 of the failing file when there is a problem reading it.
bbe902f0
PH
2966
296726. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 2968 As per change 25.
bbe902f0 2969
ea3a6f44
NM
297027. Reset the locale to "C" after calling embedded Perl, in case it was changed
2971 (this can affect the format of dates).
bbe902f0 2972
ea3a6f44
NM
297328. exim_tidydb, when checking for the continued existence of a message for
2974 which it has found a message-specific retry record, was not finding
2975 messages that were in split spool directories. Consequently, it was
2976 deleting retry records that should have stayed in existence.
bbe902f0
PH
2977
297829. eximstats updated to version 1.35
2979 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
2980 1.35 - bugfix such that pie charts by volume are generated correctly
2981
ea3a6f44
NM
298230. The SPA authentication driver was not abandoning authentication and moving
2983 on to the next authenticator when an expansion was forced to fail,
2984 contradicting the general specification for all authenticators. Instead it
2985 was generating a temporary error. It now behaves as specified.
bbe902f0 2986
ea3a6f44
NM
298731. The default ordering of permitted cipher suites for GnuTLS was pessimal
2988 (the order specifies the preference for clients). The order is now AES256,
2989 AES128, 3DES, ARCFOUR128.
bbe902f0 2990
ea3a6f44
NM
299131. Small patch to Sieve code - explicitly set From: when generating an
2992 autoreply.
bbe902f0 2993
ea3a6f44
NM
299432. Exim crashed if a remote delivery caused a very long error message to be
2995 recorded - for instance if somebody sent an entire SpamAssassin report back
2996 as a large number of 550 error lines. This bug was coincidentally fixed by
2997 increasing the size of one of Exim's internal buffers (big_buffer) that
2998 happened as part of the Exiscan merge. However, to be on the safe side, I
2999 have made the code more robust (and fixed the comments that describe what
3000 is going on).
bbe902f0 3001
ea3a6f44
NM
300233. Some experimental protocols are using DNS PTR records for new purposes. The
3003 keys for these records are domain names, not reversed IP addresses. The
3004 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3005 leaves it alone. Component reversal etc. now happens only for IP addresses.
bbe902f0
PH
3006 CAN-2005-0021
3007
ea3a6f44
NM
300834. The host_aton() function is supposed to be passed a string that is known
3009 to be a valid IP address. However, in the case of IPv6 addresses, it was
3010 not checking this. This is a hostage to fortune. Exim now panics and dies
3011 if the condition is not met. A case was found where this could be provoked
3012 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3013 components; fortuitously, this particular loophole had already been fixed
3014 by change 4.50/55 or 4.44/33 above.
3015
3016 If there are any other similar loopholes, the new check in host_aton()
3017 itself should stop them being exploited. The report I received stated that
3018 data on the command line could provoke the exploit when Exim was running as
3019 exim, but did not say which command line option was involved. All I could
3020 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3021 running as the user.
bbe902f0
PH
3022 CAN-2005-0021
3023
ea3a6f44
NM
302435. There was a buffer overflow vulnerability in the SPA authentication code
3025 (which came originally from the Samba project). I have added a test to the
3026 spa_base64_to_bits() function which I hope fixes it.
bbe902f0
PH
3027 CAN-2005-0022
3028
ea3a6f44
NM
302936. The daemon start-up calls getloadavg() while still root for those OS that
3030 need the first call to be done as root, but it missed one case: when
3031 deliver_queue_load_max is set with deliver_drop_privilege. This is
3032 necessary for the benefit of the queue runner, because there is no re-exec
3033 when deliver_drop_privilege is set.
bbe902f0 3034
ea3a6f44
NM
303537. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3036 was in use, was not putting the data itself into the right store pool;
3037 consequently, it could be overwritten for a subsequent message in the same
3038 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3039 the caching.)
bbe902f0 3040
ea3a6f44
NM
304138. Sometimes the final signoff response after QUIT could fail to get
3042 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3043 < 0 before doing a fflush(). This bug looks as though it goes back to the
3044 introduction of TLS in release 3.20, but "sometimes" must have been rare
3045 because the tests only now provoked it.

3048Exim version 4.43
3049-----------------
3050
3051 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3052 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3053 Now it returns an integer. A number of calls were still expecting a T/F
3054 return. Fortuitously, in all cases, the tests worked in OK situations,
3055 which is the norm. However, things would have gone wrong on any write
3056 failures on the smtp file descriptor. This function is used when sending
3057 messages over SMTP and also when doing verify callouts.
3058
3059 2. When Exim is called to do synchronous delivery of a locally submitted
3060 message (the -odf or -odi options), it no longer closes stderr before doing
3061 the delivery.
3062
3063 3. Implemented the mua_wrapper option.
3064
3065 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3066
3067 5. Implemented the functions header_remove(), header_testname(),
3068 header_add_at_position(), and receive_remove_recipient(), and exported them
3069 to local_scan().
3070
3071 6. If an ACL "warn" statement specified the addition of headers, Exim already
3072 inserted X-ACL-Warn: at the start if there was no header name. However, it
3073 was not making this test for the second and subsequent header lines if
3074 there were newlines in the string. This meant that an invalid header could
3075 be inserted if Exim was badly configured.
3076
3077 7. Allow an ACL "warn" statement to add header lines at the start or after all
3078 the Received: headers, as well as at the end.
3079
3080 8. Added the rcpt_4xx retry error code.
3081
3082 9. Added postmaster_mailfrom=xxx to callout verification option.
3083
308410. Added mailfrom=xxxx to the callout verification option, for verify=
3085 header_sender only.
3086
308711. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3088 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3089
309012. Inserted some casts to stop certain compilers warning when using pointer
3091 differences as field lengths or precisions in printf-type calls (mostly
3092 affecting debugging statements).
3093
309413. Added optional readline() support for -be (dynamically loaded).
3095
309614. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3097 same clock tick as a message's arrival, so that its received time was the
3098 same as the "first fail" time on the retry record, and that message
3099 remained on the queue past the ultimate address timeout, every queue runner
3100 would try a delivery (because it was past the ultimate address timeout) but
3101 after another failure, the ultimate address timeout, which should have then
3102 bounced the address, did not kick in. This was a "< instead of <=" error;
3103 in most cases the first failure would have been in the next clock tick
3104 after the received time, and all would be well.
3105
310615. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3107 being recognized when the domain list was tested by the match_domain
3108 condition in an expansion string.
3109
311016. Added the ${str2b64: operator.
3111
311217. Exim was always calling setrlimit() to set a large limit for the number of
3113 processes, without checking whether the existing limit was already
3114 adequate. (It did check for the limit on file descriptors.) Furthermore,
3115 errors from getrlimit() and setrlimit() were being ignored. Now they are
3116 logged to the main and panic logs, but Exim does carry on, to try to do its
3117 job under whatever limits there are.
3118
311918. Imported PCRE 5.0.
3120
312119. Trivial typo in log message " temporarily refused connection" (the leading
3122 space).
3123
312420. If the log selector return_path_on_delivery was set and an address was
3125 redirected to /dev/null, the delivery process crashed because it assumed
3126 that a return path would always be set for a "successful" delivery. In this
3127 case, the whole delivery is bypassed as an optimization, and therefore no
3128 return path is set.
3129
313021. Internal re-arrangement: the function for sending a challenge and reading
3131 a response while authentication was assuming a zero-terminated challenge
3132 string. It's now changed to take a pointer and a length, to allow for
3133 binary data in such strings.
3134
313522. Added the cyrus_sasl authenticator (code supplied by MBM).
3136
313723. Exim was not respecting finduser_retries when seeking the login of the
3138 uid under which it was called; it was always trying 10 times. (The default
3139 setting of finduser_retries is zero.) Also, it was sleeping after the final
3140 failure, which is pointless.
3141
314224. Implemented tls_on_connect_ports.
3143
314425. Implemented acl_smtp_predata.
3145
314626. If the domain in control=submission is set empty, Exim assumes that the
3147 authenticated id is a complete email address when it generates From: or
3148 Sender: header lines.
3149
315027. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3151 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3152 chown and chgrp in /bin and hostname in /usr/bin.
3153
315428. Exim was keeping the "process log" file open after each use, just as it
3155 does for the main log. This opens the possibility of it remaining open for
3156 long periods when the USR1 signal hits a daemon. Occasional processlog
3157 errors were reported, that could have been caused by this. Anyway, it seems
3158 much more sensible not to leave this file open at all, so that is what now
3159 happens.
3160
316129. The long-running daemon process does not normally write to the log once it
3162 has entered its main loop, and it closes the log before doing so. This is
3163 so that log files can straightforwardly be renamed and moved. However,
3164 there are a couple of unusual error situations where the daemon does write
3165 log entries, and I had neglected to close the log afterwards.
3166
316730. The text of an SMTP error response that was received during a remote
3168 delivery was being truncated at 512 bytes. This is too short for some of
3169 the long messages that one sometimes sees. I've increased the limit to
3170 1024.
3171
317231. It is now possible to make retry rules that apply only when a message has a
3173 specific sender, in particular, an empty sender.
3174
317532. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3176 it possible to be selective about when SMTP synchronization is enforced.
3177
317833. Added "control = caseful_local_part" and "control = "caselower_local_part".
3179
318032. Implemented hosts_connection_nolog.
3181
318233. Added an ACL for QUIT.
3183
318434. Setting "delay_warning=" to disable warnings was not working; it gave a
3185 syntax error.
3186
318735. Added mailbox_size and mailbox_filecount to appendfile.
3188
318936. Added control = no_multiline_responses to ACLs.
3190
319137. There was a bug in the logic of the code that waits for the clock to tick
3192 in the case where the clock went backwards by a substantial amount such
3193 that the microsecond fraction of "now" was more than the microsecond
3194 fraction of "then" (but the whole seconds number was less).
3195
319638. Added support for the libradius Radius client library this is found on
3197 FreeBSD (previously only the radiusclient library was supported).
3198
3199
3200Exim version 4.42
3201-----------------
3202
3203 1. When certain lookups returned multiple values in the form name=value, the
3204 quoting of the values was not always being done properly. Specifically:
3205 (a) If the value started with a double quote, but contained no whitespace,
3206 it was not quoted.
3207 (b) If the value contained whitespace other than a space character (i.e.
3208 tabs or newlines or carriage returns) it was not quoted.
3209 This fix has been applied to the mysql and pgsql lookups by writing a
3210 separate quoting function and calling it from the lookup code. The fix
3211 should probably also be applied to nisplus, ibase and oracle lookups, but
3212 since I cannot test any of those, I have not disturbed their existing code.
3213
3214 2. A hit in the callout cache for a specific address caused a log line with no
3215 reason for rejecting RCPT. Now it says "Previous (cached) callout
3216 verification failure".
3217
3218 3. There was an off-by-one bug in the queryprogram router. An over-long
3219 return line was truncated at 256 instead of 255 characters, thereby
3220 overflowing its buffer with the terminating zero. As well as fixing this, I
3221 have increased the buffer size to 1024 (and made a note to document this).
3222
3223 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3224 when Exim is waiting for an SMTP response from a remote server, Exim
3225 restarts its select() call on the socket, thereby resetting its timeout.
3226 This is not a problem when such interrupts are rare. Somebody set up a cron
3227 job to run exiwhat every 2 minutes, which is less than the normal select()
3228 timeout (5 or 10 minutes). This meant that the select() timeout never
3229 kicked in because it was always reset. I have fixed this by comparing the
3230 time when an interrupt arrives with the time at the start of the first call
3231 to select(). If more time than the timeout has elapsed, the interrupt is
3232 treated as a timeout.
3233
3234 5. Some internal re-factoring in preparation for the addition of Sieve
3235 extensions (by MH). In particular, the "personal" test is moved to a
3236 separate function, and given an option for scanning Cc: and Bcc: (which is
3237 not set for Exim filters).
3238
3239 6. When Exim created an email address using the login of the caller as the
3240 local part (e.g. when creating a From: or Sender: header line), it was not
3241 quoting the local part when it contained special characters such as @.
3242
3243 7. Installed new OpenBSD configuration files.
3244
3245 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3246 try to make them clearer.
3247
3248 9. Callout options, other than the timeout value, were being ignored when
3249 verifying sender addresses in header lines. For example, when using
3250
3251 verify = header_sender/callout=no_cache
3252
3253 the cache was (incorrectly) being used.
3254
325510. Added a missing instance of ${EXE} to the exim_install script; this affects
3256 only the Cygwin environment.
3257
325811. When return_path_on_delivery was set as a log selector, if different remote
3259 addresses in the same message used different return paths and parallel
3260 remote delivery occurred, the wrong values would sometimes be logged.
3261 (Whenever a remote delivery process finished, the return path value from
3262 the most recently started remote delivery process was logged.)
3263
326412. RFC 3848 specifies standard names for the "with" phrase in Received: header
3265 lines when AUTH and/or TLS are in use. This is the "received protocol"
3266 field. Exim used to use "asmtp" for authenticated SMTP, without any
3267 indication (in the protocol name) for TLS use. Now it follows the RFC and
3268 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3269 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3270 names appear in log lines as well as in Received: header lines.
3271
327213. Installed MH's patches for Sieve to add the "copy" and "vacation"
3273 extensions, and comparison tests, and to fix some bugs.
3274
327514. Changes to the "personal" filter test:
3276
3277 (1) The test was buggy in that it was just doing the equivalent of
3278 "contains" tests on header lines. For example, if a user's address was
3279 anne@some.where, the "personal" test would incorrectly be true for
3280
3281 To: susanne@some.where
3282
3283 This test is now done by extracting each address from the header in turn,
3284 and checking the entire address. Other tests that are part of "personal"
3285 are now done using regular expressions (for example, to check local parts
3286 of addresses in From: header lines).
3287
3288 (2) The list of non-personal local parts in From: addresses has been
3289 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3290 taken from the Sieve specification recommendations.
3291
3292 (3) If the message contains any header line starting with "List-" it is
3293 treated as non-personal.
3294
3295 (4) The test for "circular" in the Subject: header line has been removed
3296 because it now seems ill-conceived.
3297
329815. Minor typos in src/EDITME comments corrected.
3299
330016. Installed latest exipick from John Jetmore.
3301
330217. If headers_add on a router specified a text string that was too long for
3303 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3304 of string_sprintf() is now avoided.
3305
330618. $message_body_size was not set (it was always zero) when running the DATA
3307 ACL and the local_scan() function.
3308
330919. For the "mail" command in an Exim filter, no default was being set for
3310 the once_repeat time, causing a random time value to be used if "once" was
3311 specified. (If the value happened to be <= 0, no repeat happened.) The
3312 default is now 0s, meaning "never repeat". The "vacation" command was OK
3313 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3314 (I found it when inspecting the code).
3315
331620. There is now an overall timeout for performing a callout verification. It
3317 defaults to 4 times the callout timeout, which applies to individual SMTP
3318 commands during the callout. The overall timeout applies when there is more
3319 than one host that can be tried. The timeout is checked before trying the
3320 next host. This prevents very long delays if there are a large number of
3321 hosts and all are timing out (e.g. when the network connections are timing
3322 out). The value of the overall timeout can be changed by specifying an
3323 additional sub-option for "callout", called "maxwait". For example:
3324
3325 verify = sender/callout=5s,maxwait=20s
3326
332721. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3328 to the end before writing, but this should make it even safer).
3329
333022. Exim was forgetting that it had advertised PIPELINING for the second and
3331 subsequent messages on an SMTP connection. It was also not resetting its
3332 memory on STARTTLS and an internal HELO.
3333
333423. When Exim logs an SMTP synchronization error within a session, it now
3335 records whether PIPELINING has been advertised or not.
3336
333724. Added 3 instances of "(long int)" casts to time_t variables that were being
3338 formatted using %ld, because on OpenBSD (and perhaps others), time_t is int
3339 rather than long int.
3340
334125. Installed the latest Cygwin configuration files from the Cygwin maintainer.
3342
334326. Added the never_mail option to autoreply.
3344
3345
3346Exim version 4.41
3347-----------------
3348
3349 1. A reorganization of the code in order to implement 4.40/8 caused a daemon
3350 crash if the getsockname() call failed; this can happen if a connection is
3351 closed very soon after it is established. The problem was simply in the
3352 order in which certain operations were done, causing Exim to try to write
3353 to the SMTP stream before it had set up the file descriptor. The bug has
3354 been fixed by making things happen in the correct order.
3355
3356
3357Exim version 4.40
3358-----------------
3359
3360 1. If "drop" was used in a DATA ACL, the SMTP output buffer was not flushed
3361 before the connection was closed, thus losing the rejection response.
3362
3363 2. Commented out the definition of SOCKLEN_T in os.h-SunOS5. It is needed for
3364 some early Solaris releases, but causes trouble in current releases where
3365 socklen_t is defined.
3366
3367 3. When std{in,out,err} are closed, re-open them to /dev/null so that they
3368 always exist.
3369
3370 4. Minor refactoring of os.c-Linux to avoid compiler warning when IPv6 is not
3371 configured.
3372
3373 5. Refactoring in expand.c to improve memory usage. Pre-allocate a block so
3374 that releasing the top of it at the end releases what was used for sub-
3375 expansions (unless the block got too big). However, discard this block if
3376 the first thing is a variable or header, so that we can use its block when
3377 it is dynamic (useful for very large $message_headers, for example).
3378
3379 6. Lookups now cache *every* query, not just the most recent. A new, separate
3380 store pool is used for this. It can be recovered when all lookup caches are
3381 flushed. Lookups now release memory at the end of their result strings.
3382 This has involved some general refactoring of the lookup sources.
3383
3384 7. Some code has been added to the store_xxx() functions to reduce the amount
3385 of flapping under certain conditions.
3386
3387 8. log_incoming_interface used to affect only the <= reception log lines. Now
3388 it causes the local interface and port to be added to several more SMTP log
3389 lines, for example "SMTP connection from", and rejection lines.
3390
3391 9. The Sieve author supplied some patches for the doc/README.SIEVE file.
3392
339310. Added a conditional definition of _BSD_SOCKLEN_T to os.h-Darwin.
3394
339511. If $host_data was set by virtue of a hosts lookup in an ACL, its value
3396 could be overwritten at the end of the current message (or the start of a
3397 new message if it was set in a HELO ACL). The value is now preserved for
3398 the duration of the SMTP connection.
3399
340012. If a transport had a headers_rewrite setting, and a matching header line
3401 contained an unqualified address, that address was qualified, even if it
3402 did not match any rewriting rules. The underlying bug was that the values
3403 of the flags that permit the existence of unqualified sender and recipient
3404 addresses in header lines (set by {sender,recipient}_unqualified_hosts for
3405 non-local messages, and by -bnq for local messages) were not being
3406 preserved with the message after it was received.
3407
340813. When Exim was logging an SMTP synchronization error, it could sometimes log
3409 "next input=" as part of the text comprising the host identity instead of
3410 the correct text. The code was using the same buffer for two different
3411 strings. However, depending on which order the printing function evaluated
3412 its arguments, the bug did not always show up. Under Linux, for example, my
3413 test suite worked just fine.
3414
341514. Exigrep contained a use of Perl's "our" scoping after change 4.31/70. This
3416 doesn't work with some older versions of Perl. It has been changed to "my",
3417 which in any case is probably the better facility to use.
3418
341915. A really picky compiler found some instances of statements for creating
3420 error messages that either had too many or two few arguments for the format
3421 string.
3422
342316. The size of the buffer for calls to the DNS resolver has been increased
3424 from 1024 to 2048. A larger buffer is needed when performing PTR lookups
3425 for addresses that have a lot of PTR records. This alleviates a problem; it
3426 does not fully solve it.
3427
342817. A dnsdb lookup for PTR records that receives more data than will fit in the
3429 buffer now truncates the list and logs the incident, which is the same
3430 action as happens when Exim is looking up a host name and its aliases.
3431 Previously in this situation something unpredictable would happen;
3432 sometimes it was "internal error: store_reset failed".
3433
343418. If a server dropped the connection unexpectedly when an Exim client was
3435 using GnuTLS and trying to read a response, the client delivery process
3436 crashed while trying to generate an error log message.
3437
343819. If a "warn" verb in an ACL added multiple headers to a message in a single
3439 string, for example:
3440
3441 warn message = H1: something\nH2: something
3442
3443 the text was added as a single header line from Exim's point of view
3444 though it ended up OK in the delivered message. However, searching for the
3445 second and subsequent header lines using $h_h2: did not work. This has been
3446 fixed. Similarly, if a system filter added multiple headers in this way,
3447 the routers could not see them.
3448
344920. Expanded the error message when iplsearch is called with an invalid key to
3450 suggest using net-iplsearch in a host list.
3451
345221. When running tests using -bh, any delays imposed by "delay" modifiers in
3453 ACLs are no longer actually imposed (and a message to that effect is
3454 output).
3455
345622. If a "gecos" field in a passwd entry contained escaped characters, in
3457 particular, if it contained a \" sequence, Exim got it wrong when building
3458 a From: or a Sender: header from that name. A second bug also caused
3459 incorrect handling when an unquoted " was present following a character
3460 that needed quoting.
3461
346223. "{crypt}" as a password encryption mechanism for a "crypteq" expansion item
3463 was not being matched caselessly.
3464
346524. Arranged for all hyphens in the exim.8 source to be escaped with
3466 backslashes.
3467
346825. Change 16 of 4.32, which reversed 71 or 4.31 didn't quite do the job
3469 properly. Recipient callout cache records were still being keyed to include
3470 the sender, even when use_sender was set false. This led to far more
3471 callouts that were necessary. The sender is no longer included in the key
3472 when use_sender is false.
3473
347426. Added "control = submission" modifier to ACLs.
3475
347627. Added the ${base62d: operator to decode base 62 numbers.
3477
347828. dnsdb lookups can now access SRV records.
3479
348029. CONFIGURE_OWNER can be set at build time to define an alternative owner for
3481 the configuration file.
3482
348330. The debug message "delivering xxxxxx-xxxxxx-xx" is now output in verbose
3484 (-v) mode. This makes the output for a verbose queue run more intelligible.
3485
348631. Added a use_postmaster feature to recipient callouts.
3487
348832. Added the $body_zerocount variable, containing the number of binary zero
3489 bytes in the message body.
3490
349133. The time of last modification of the "new" subdirectory is now used as the
3492 "mailbox time last read" when there is a quota error for a maildir
3493 delivery.
3494
349534. Added string comparison operators lt, lti, le, lei, gt, gti, ge, gei.
3496
349735. Added +ignore_unknown as a special item in host lists.
3498
349936. Code for decoding IPv6 addresses in host lists is now included, even if
3500 IPv6 support is not being compiled. This fixes a bug in which an IPv6
3501 address was recognized as an IP address, but was then not correctly decoded
