9PP/01 Date: & Message-Id: revert to normally being appended to a message,

PP
26PP/07 If TLS negotiated an anonymous cipher, we could end up with SSL but
27 without a peer certificate (I believe), leading to a segfault because of
28 an assumption that peers always have certificates. Be a little more
29 paranoid. Problem reported by Martin Tscholak.

TK
271TK/01 Add preliminary DKIM support. Currently requires a forked version of
272 ALT-N's libdkim that I have put here:
273 http://duncanthrax.net/exim-experimental/
274
275 Note to Michael Haardt: I had to rename some vars in sieve.c. They
276 were called 'true' and it seems that C99 defines that as a reserved
277 keyword to be used with 'bool' variable types. That means you could
278 not include C99-style headers which use bools without triggering
279 build errors in sieve.c.

281NM/01 Bugzilla 592: --help option is handled incorrectly if exim is invoked

294Exim version 4.68
295-----------------
296
297PH/01 Another patch from the Sieve maintainer.
298
6a3bceb1
PH
299PH/02 When an IPv6 address is converted to a string for single-key lookup
300 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
301 dots are used instead of colons so that keys in lsearch files need not
302 contain colons. This was done some time before quoting was made available
303 in lsearch files. However, iplsearch files do require colons in IPv6 keys
304 (notated using the quote facility) so as to distinguish them from IPv4
305 keys. This meant that lookups for IP addresses in host lists did not work
306 for iplsearch lookups.
307
308 This has been fixed by arranging for IPv6 addresses to be expressed with
309 colons if the lookup type is iplsearch. This is not incompatible, because
310 previously such lookups could never work.
311
312 The situation is now rather anomolous, since one *can* have colons in
313 ordinary lsearch keys. However, making the change in all cases is
314 incompatible and would probably break a number of configurations.
315
2e30fa9d
TK
316TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
317 version.
318
0806a9c5
MH
319MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
320 conversion specification without a maximum field width, thereby enabling
321 a rogue spamd server to cause a buffer overflow. While nobody in their
322 right mind would setup Exim to query an untrusted spamd server, an
323 attacker that gains access to a server running spamd could potentially
324 exploit this vulnerability to run arbitrary code as the Exim user.
325

TK
326TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
327 $primary_hostname instead of what libspf2 thinks the hosts name is.
328
0f2cbd1b
MH
329MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
330 a directory entry by the name of the lookup key. Previously, if a
331 symlink pointed to a non-existing file or a file in a directory that
332 Exim lacked permissions to read, a lookup for a key matching that
333 symlink would fail. Now it is enough that a matching directory entry
334 exists, symlink or not. (Bugzilla 503.)

342 This means they are set thereafter only if the connection becomes

PH
374PH/18 If a system quota error occurred while trying to create the file for
375 a maildir delivery, the message "Mailbox is full" was not appended to the
376 bounce if the delivery eventually timed out. Change 4.67/27 below applied
377 only to a quota excession during the actual writing of the file.
d6a60c0f 378
ddea74fa 379PH/19 It seems that peer DN values may contain newlines (and other non-printing

380 characters?) which causes problems in log lines. The DN values are now
381 passed through string_printing() before being added to log lines.

517PH/29 SMTP synchronization checks are implemented when a command is read -
518 there is a check that no more input is waiting when there shouldn't be

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

597 the response to the final '.' that terminates a message, but only in the
598 case where the client has not sent further data following the '.'
599 (unfortunately, this is allowed). However, in many cases there won't be
600 any further data because there won't be any more messages to send. A call
601 to select() can be used: if it shows that the input is "ready", there is
602 either input waiting, or the socket has been closed. An attempt to read
603 the next input character can distinguish the two cases. Previously, Exim
58eb016e 604 would have sent an OK response which the client would never have see.

614
615PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
616 fixed by 4.65/MH/01 (is this a record?) are fixed:
617
618 (i) An empty string was always treated as zero by the numeric comparison
619 operators. This behaviour has been restored.
620
621 (ii) It is documented that the numeric comparison operators always treat
622 their arguments as decimal numbers. This was broken in that numbers
623 starting with 0 were being interpreted as octal.
624
625 While fixing these problems I realized that there was another issue that
626 hadn't been noticed. Values of message_size_limit (both the global option
627 and the transport option) were treated as octal if they started with 0.
628 The documentation was vague. These values are now always treated as
629 decimal, and I will make that clear in the documentation.

645 is held in a short int, deliveries were likely to be lost. As such a
646 large number of recipients for a single message is ridiculous
647 (performance will be very, very poor), I have chosen to impose a limit
648 rather than extend the field.

654TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a

2b1c6e3a
PH
673PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
674 callout verification, Exim cached a "reject" for the entire domain. This
675 is correct for most verifications, but it is not correct for a recipient
676 verification with use_sender or use_postmaster set, because in that case
677 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
678 case of MAIL FROM:<> rejection from other early rejections (e.g.
679 rejection of HELO). When verifying a recipient using a non-null MAIL
680 address, the cache is ignored if it shows MAIL FROM:<> rejection.
681 Whatever the result of the callout, the value of the domain cache is
682 left unchanged (for any other kind of callout, getting as far as trying
683 RCPT means that the domain itself is ok).

717PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

719 probably the interface on which it is arriving) and not to the outgoing
720 callout (which could be using a different interface). This has been
721 changed to use the value of the helo_data option from the smtp transport
722 instead - this is what is used when a message is actually being sent. If
723 there is no remote transport (possible with a router that sets up host
724 addresses), $smtp_active_hostname is used.

14aa5a05 726PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 727 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
728 (a) The code assumed that strncpy() returns a negative number on buffer
729 overflow, which isn't the case. Replaced with Exim's string_format()
730 function.
731 (b) There were several signed/unsigned issues. I just did the minimum
732 hacking in of casts. There is scope for a larger refactoring.
733 (c) The code used strcasecmp() which is not a standard C function.
734 Replaced with Exim's strcmpic() function.
735 (d) The code set only $1; it now sets $auth1 as well.
736 (e) A simple test gave the error "authentication client didn't specify
737 service in request". It would seem that Dovecot has changed its
738 interface. Fortunately there's a specification; I followed it and
739 changed what the client sends and it appears to be working now.

744PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
745 address A is aliased to B and C, where B exists and C does not. Without
746 -v the output is "A verified" because verification stops after a
747 successful redirection if more than one address is generated. However,
748 with -v the child addresses are also verified. Exim was outputting "A
749 failed to verify" and then showing the successful verification for C,
750 with its parentage. It now outputs "B failed to verify", showing B's
751 parentage before showing the successful verification of C.

756
322050c2
PH
757PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
758 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
759 they consult the DNS. I had assumed they would set it the way they
760 wanted; and indeed my experiments on Linux seem to show that in some
761 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
762 To be on the safe side, however, I have now made the interface to
763 host_find_byname() similar to host_find_bydns(), with an argument
764 containing the DNS resolver options. The host_find_byname() function now
765 sets these options at its start, just as host_find_bydns() does. The smtp
766 transport options dns_qualify_single and dns_search_parents are passed to
767 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
768 of host_find_byname() use the default settings of RES_DEFNAMES
769 (qualify_single) but not RES_DNSRCH (search_parents).

771PH/17 Applied (a modified version of) Nico Erfurth's patch to make
772 spool_read_header() do less string testing, by means of a preliminary
773 switch on the second character of optional "-foo" lines. (This is
774 overdue, caused by the large number of possibilities that now exist.
775 Originally there were few.) While I was there, I also converted the
776 str(n)cmp tests so they don't re-test the leading "-" and the first
777 character, in the hope this might squeeze out yet more improvement.

PH
779PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
780 flag allowing group syntax was set by the header_syntax check but not
781 turned off, possible causing trouble later; (2) The flag was not being
782 set at all for the header_verify test, causing "group"-style headers to
783 be rejected. I have now set it in this case, and also caused header_
784 verify to ignore an empty address taken from a group. While doing this, I
785 came across some other cases where the code for allowing group syntax
786 while scanning a header line wasn't quite right (mostly, not resetting
787 the flag correctly in the right place). These bugs could have caused
788 trouble for malformed header lines. I hope it is now all correct.

794 code for some other use. I have removed all the tests.

PH
796PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
797 feature that was used to support insecure browsers during the U.S. crypto
798 embargo. It requires special client support, and Exim is probably the
799 only MTA that supported it -- and would never use it because real RSA is
800 always available. This code has been removed, because it had the bad
801 effect of slowing Exim down by computing (never used) parameters for the
802 RSA_EXPORT functionality.

804PH/21 On the advice of Timo Sirainen, added a check to the dovecot
805 authenticator to fail if there's a tab character in the incoming data
806 (there should never be unless someone is messing about, as it's supposed
807 to be base64-encoded). Also added, on Timo's advice, the "secured" option
808 if the connection is using TLS or if the remote IP is the same as the
809 local IP, and the "valid-client-cert option" if a client certificate has
810 been verified.

841
842PH/30 Exim was sometimes attempting to deliver messages that had suffered
843 address errors (4xx response to RCPT) over the same connection as other
844 messages routed to the same hosts. Such deliveries are always "forced",
845 so retry times are not inspected. This resulted in far too many retries
846 for the affected addresses. The effect occurred only when there were more
847 hosts than the hosts_max_try setting in the smtp transport when it had
848 the 4xx errors. Those hosts that it had tried were not added to the list
849 of hosts for which the message was waiting, so if all were tried, there
850 was no problem. Two fixes have been applied:
851
852 (i) If there are any address or message errors in an SMTP delivery, none
853 of the hosts (tried or untried) are now added to the list of hosts
854 for which the message is waiting, so the message should not be a
855 candidate for sending over the same connection that was used for a
856 successful delivery of some other message. This seems entirely
857 reasonable: after all the message is NOT "waiting for some host".
858 This is so "obvious" that I'm not sure why it wasn't done
859 previously. Hope I haven't missed anything, but it can't do any
860 harm, as the worst effect is to miss an optimization.
861
862 (ii) If, despite (i), such a delivery is accidentally attempted, the
863 routing retry time is respected, so at least it doesn't keep
864 hammering the server.

879PH/35 The error "getsockname() failed: connection reset by peer" was being
880 written to the panic log as well as the main log, but it isn't really
881 panic-worthy as it just means the connection died rather early on. I have
882 removed the panic log writing for the ECONNRESET error when getsockname()
883 fails.
884
48c7f9e2
PH
885PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
886 runs only) independently of the message's sender address. This meant
887 that, if the 4xx error was in fact related to the sender, a different
888 message to the same recipient with a different sender could confuse
889 things. In particualar, this can happen when sending to a greylisting
890 server, but other circumstances could also provoke similar problems.
891 I have changed the default so that the retry time for these errors is now
892 based a combination of the sender and recipient addresses. This change
893 can be overridden by setting address_retry_include_sender=false in the
894 smtp transport.

1167 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1168 554 error is used if errno is still zero or contains ENOENT (which occurs

1192PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1193 folder from quota calculations, a direct delivery into this folder messed
1194 up the contents of the maildirsize file. This was because the regex was
1195 used only to exclude .Trash (or whatever) when the size of the mailbox
1196 was calculated. There was no check that a delivery was happening into an
1197 excluded directory. This bug has been fixed by ignoring all quota
1198 processing for deliveries into excluded directories.

1205
1206PH/01 The code for finding all the local interface addresses on a FreeBSD
1207 system running IPv6 was broken. This may well have applied to all BSD
1208 systems, as well as to others that have similar system calls. The broken
1209 code found IPv4 interfaces correctly, but gave incorrect values for the
1210 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1211 that it would not match correctly against @[] and not recognize the IPv6
1212 addresses as local.

1255 autoreply, Exim could try to deliver to a non-existent relative file

1275 non-existent - all you got was a failure to exec. I have made two
1276 changes:
1277
1278 (a) Failures to set uid/gid, the current directory, or a process leader
1279 in a subprocess such as that created by queryprogram now generate
1280 suitable debugging ouput when -d is set.

1289PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1290 additional section of a DNS packet that returns MX or SRV records.
1291 Instead, it always explicitly searches for A/AAAA records. This avoids
1292 major problems that occur when a DNS server includes only records of one
1293 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1294 fixed another bug: if SRV records were looked up and the corresponding
1295 address records were *not* found in the additional section, the port
1296 values from the SRV records were lost.

PH
1306PH/19 When calculating a retry time, Exim used to measure the "time since
1307 failure" by looking at the "first failed" field in the retry record. Now
1308 it does not use this if it is later than than the arrival time of the
1309 message. Instead it uses the arrival time. This makes for better
1310 behaviour in cases where some deliveries succeed, thus re-setting the
1311 "first failed" field. An example is a quota failure for a huge message
1312 when small messages continue to be delivered. Without this change, the
1313 "time since failure" will always be short, possible causing more frequent
1314 delivery attempts for the huge message than are intended.

PH
1411PH/42 The content-scanning code uses fopen() to create files in which to put
1412 message data. Previously it was not paying any attention to the mode of
1413 the files. Exim runs with umask(0) because the rest of the code creates
1414 files with open(), and sets the required mode explicitly. Thus, these
1415 files were ending up world-writeable. This was not a big issue, because,
1416 being within the spool directory, they were not world-accessible. I have
1417 created a function called modefopen, which takes an additional mode
1418 argument. It sets umask(777), creates the file, chmods it to the required
1419 mode, then resets the umask. All the relevant calls to fopen() in the
1420 content scanning code have been changed to use this function.

1432 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

1457
1458 (i) Exim was not creating retry information for temporary errors given
1459 for individual recipients after the DATA command when the smtp transport
1460 was used in LMTP mode. This meant that they could be retried too
1461 frequently, and not timed out correctly.
1462
1463 (ii) Exim was setting the flag that allows error details to be returned
1464 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1465 recipients that were returned after the DATA command.
1466
1467PH/53 This is related to PH/52, but is more general: for any failing address,
1468 when detailed error information was permitted to be returned to the
1469 sender, but the error was temporary, then after the final timeout, only

1541PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1542 function verify_get_ident() calls ip_connect() to connect a socket, but
1543 if the "connect()" function timed out, ip_connect() used to close the
1544 socket. However, verify_get_ident() also closes the socket later, and in
1545 between Exim writes to the log, which may get opened at this point. When
1546 the socket was closed in ip_connect(), the log could get the same file
1547 descriptor number as the socket. This naturally causes chaos. The fix is
1548 not to close the socket in ip_connect(); the socket should be closed by
1549 the function that creates it. There was only one place in the code where
1550 this was missing, in the iplookup router, which I don't think anybody now
1551 uses, but I've fixed it anyway.

1607PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1608 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1609 not being looked up in the rDNS to get a host name, Exim was showing the
1610 IP address twice in Received: lines, even though the IP addresses were
1611 identical. For example:
1612
1613 Received: from [1.2.3.4] (helo=[1.2.3.4])
1614
1615 However, if the real host name was known, it was omitting the HELO data
1616 if it matched the actual IP address. This has been tidied up so that it
1617 doesn't show the same IP address twice.

1643PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

1645
1646 Auto-submitted: auto-generated
1647
1648 in the messages that it generates (bounce messages and others, such as
1649 warnings). In the case of bounce messages for non-SMTP mesages, there was
1650 also a typo: it was using "Auto_submitted" (underscore instead of
1651 hyphen). Since every message generated by Exim is necessarily in response
1652 to another message, thes have all been changed to:
1653
1654 Auto-Submitted: auto-replied
1655
1656 in accordance with these statements in the RFC:
1657
1658 The auto-replied keyword:
1659
1660 - SHOULD be used on messages sent in direct response to another
1661 message by an automatic process,
1662

1706PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1707 canonical form (as documented). However, after a host name lookup from
1708 the IP address, check_host() was doing a simple string comparison with
1709 addresses acquired from the DNS when checking that the found name did
1710 have the original IP as one of its addresses. Since any found IPv6
1711 addresses are likely to be in abbreviated form, the comparison could
1712 fail. Luckily, there already exists a function for doing the comparison
1713 by converting both addresses to binary, so now that is used instead of
1714 the text comparison.

2011PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2012 with the definition in sysexits.h (which is #included earlier).
2013 Fortunately, Exim does not actually use EX_OK. The code used to try to
2014 preserve the sysexits.h value, by assumimg that macro definitions were
2015 scanned for macro replacements. I have been disabused of this notion,
2016 so now the code just undefines EX_OK before #including unistd.h.

2021 This seems wrong - if the receiver was accepting one byte at a time it
2022 would take for ever. The timeout is now adjusted when this happens. It
2023 doesn't have to be particularly precise.

2231
2232PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2233 that changes the way the GnuTLS parameters are stored in the cache file.
2234 The new format can be generated externally. For backward compatibility,
2235 if the data in the cache doesn't make sense, Exim assumes it has read an
2236 old-format file, and it generates new data and writes a new file. This
2237 means that you can't go back to an older release without removing the
2238 file.
2239
2240PH/03 A redirect router that has both "unseen" and "one_time" set does not
2241 work if there are any delivery delays because "one_time" forces the
2242 parent to be marked "delivered", so its unseen clone is never tried
2243 again. For this reason, Exim now forbids the simultaneous setting of
2244 these two options.
2245
2246PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2247 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2248 entry if you want to know the details. The fix, however, neglected to
2249 consider the case when local delivery batching is involved. The test for
2250 "previously delivered" was not happening when checking to see if an
2251 address could be batched with a previous (undelivered) one; under
2252 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2253 address.

2255PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2258PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2259 header_syntax) but Exim was just ignoring anything given after a slash.
2260 In particular, this caused confusion with an attempt to use "verify =
2261 reverse_host_lookup/defer_ok". An error is now given when options are
2262 supplied for verify items that do not have them. (Maybe reverse_host_
2263 lookup should have a defer_ok option, but that's a different point.)

2265PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2318 the file with the wrong ownership). There was no test for failure of this
2319 fork() call, which would lead to the process getting stuck as it waited

2341PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2342 hadn't been configured. The fix is from Juergen Kreileder, who
2343 understands it better than I do:
2344
2345 "Here's what I see happening with three configured cyrus_sasl
2346 authenticators configured (plain, login, cram-md5):
2347
2348 On startup auth_cyrus_sasl_init() gets called for each of these.
2349 This means three calls to sasl_listmech() without a specified mech_list.
2350 => SASL tests which mechs of all available mechs actually work
2351 => three warnings about OTP not working
2352 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2353
2354 With the patch, sasl_listmech() also gets called three times. But now
2355 SASL's mech_list option is set to the server_mech specified in the the
2356 authenticator. Or in other words, the answer from sasl_listmech()
2357 gets limited to just the mech you're testing for (which is different
2358 for each call.)
2359 => the return list contains just 'plain' or 'login', 'cram-md5' or
2360 nothing depending on the value of ob->server_mech.
2361

2395PH/30 In these circumstances:
2396 . Two addresses routed to the same list of hosts;
2397 . First host does not offer TLS;
2398 . First host accepts first address;
2399 . First host gives temporary error to second address;
2400 . Second host offers TLS and a TLS session is established;
2401 . Second host accepts second address.
2402 Exim incorrectly logged both deliveries with the TLS parameters (cipher
2403 and peerdn, if requested) that were in fact used only for the second
2404 address.

2406PH/31 When doing a callout as part of verifying an address, Exim was not paying
2407 attention to any local part prefix or suffix that was matched by the

2409 does for delivery: the affixes are removed from the local part unless

PH
2428PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2429 the grounds that routing the same address twice would always produce the
2430 same answer. This might have been true once, but it is certainly no
2431 longer true now. Routing a child address may depend on the previous
2432 routing that produced that child. Some complicated redirection strategies
2433 went wrong when messages had multiple recipients, and made Exim's
2434 behaviour dependent on the order in which the addresses were given.
2435
2436 I have moved the duplicate checking until after the routing is complete.
2437 Exim scans the addresses that are assigned to local and remote
2438 transports, and removes any duplicates. This means that more work will be
2439 done, as duplicates will always all be routed, but duplicates are
2440 presumably rare, so I don't expect this is of any significance.
2441
2442 For deliveries to pipes, files, and autoreplies, the duplicate checking
2443 still happens during the routing process, since they are not going to be
2444 routed further.

2449 connection it has accepted, or it never writes response data. The exiscan
2450 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2451 blindly assumes that writes won't block so it may never time out."

2471 (c) A message specified in a "fail" command in a system filter;
2472 (d) A message specified in a FAIL return from the queryprogram router;
2473 (e) A message specified by the cannot_route_message router option.
2474
2475 In these cases only, Exim does include the error details in bounce and
2476 warning messages. There are also a few cases where bland messages such
2477 as "unrouteable address" or "local delivery error" are given.

2485PH/45 In a pipe transport, although a timeout while waiting for the pipe
2486 process to complete was treated as a delivery failure, a timeout while

2488 successful delivery. Such timeouts include transport filter timeouts. For
2489 consistency with the overall process timeout, these timeouts are now
2490 treated as errors, giving rise to delivery failures by default. However,
2491 there is now a new Boolean option for the pipe transport called
2492 timeout_defer, which, if set TRUE, converts the failures into defers for
2493 both kinds of timeout. A transport filter timeout is now identified in
2494 the log output.

2503A note about Exim versions 4.44 and 4.50
2504----------------------------------------
2505
2506Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2507changes of various kinds. As a consequence, a big documentation update was
2508needed. This delayed the release for rather longer than seemed good, especially
2509in the light of a couple of (minor) security issues. Therefore, the changes
2510that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2511release. So 4.44 and 4.50 are in effect two different branches that both start
2512from 4.43.
2513
2514I have left the 4.50 change log unchanged; it contains all the changes since
25154.43. The change log for 4.44 is below; many of its items are identical to
2516those for 4.50. This seems to be the most sensible way to preserve the
2517historical information.

PH
2535 5. There are several places where Exim runs a non-Exim command in a
2536 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2537 was being done only for the command run by the queryprogram router. It is
2538 now done for all such subprocesses. The other cases are: ${run, transport
2539 filters, and the commands run by the lmtp and pipe transports.

2541 6. Added CONFIGURE_GROUP build-time option.
2542
2543 7. Some older OS have a limit of 256 on the maximum number of file
2544 descriptors. Exim was using setrlimit() to set 1000 as a large value
2545 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2546 systems. I've change it so that if it can't get 1000, it tries for 256.

2548 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2549 was an oversight, and furthermore, ever since the addition of extra
2550 controls (e.g. 4.43/32), the checks on when to allow different forms of
2551 "control" were broken. There should now be diagnostics for all cases when a
2552 control that does not make sense is encountered.

259322. $host_address is now set to the target address during the checking of
2594 ignore_target_hosts.
2595
259623. When checking ignore_target_hosts for an ipliteral router, no host name was
2597 being passed; this would have caused $sender_host_name to have been used if
2598 matching the list had actually called for a host name (not very likely,
2599 since this list is usually IP addresses). A host name is now passed as
2600 "[x.x.x.x]".
2601
7d468ab8
PH
260224. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2603 code that specifies a non-restarting handler (typically sigaction() in
2604 modern systems) in an attempt to fix a rare and obscure crash bug.
2605
260625. Narrowed the window for a race in the daemon that could cause it to ignore
2607 SIGCHLD signals. This is not a major problem, because they are used only to
2608 wake it up if nothing else does.
2609
62c0818f
PH
261026. A malformed maildirsize file could cause Exim to calculate negative values
2611 for the mailbox size or file count. Odd effects could occur as a result.
2612 The maildirsize information is now recalculated if the size or filecount
2613 end up negative.
2614
26034054
PH
261527. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this

90af77f4
PH
262029. In an address list, if the pattern was not a regular expression, an empty
2621 subject address (from a bounce message) matched only if the pattern was an
2622 empty string. Non-empty patterns were not even tested. This was the wrong
2623 because it is perfectly reasonable to use an empty address as part of a
2624 database query. An empty address is now tested by patterns that are
2625 lookups. However, all the other forms of pattern expect the subject to
2626 contain a local part and a domain, and therefore, for them, an empty
2627 address still always fails if the pattern is not itself empty.
2628
d8ef3577
PH
262930. Exim went into a mad DNS loop when attempting to do a callout where the
2630 host was specified on an smtp transport, and looking it up yielded more
2631 than one IP address.
2632
5cb8cbc6
PH
263331. Re-factored the code for checking spool and log partition space into a
2634 function that finds that data and another that does the check. The former
2635 is then used to implement four new variables: $spool_space, $log_space,
2636 $spool_inodes, and $log_inodes.
2637
14702f5b
PH
263832. The RFC2047 encoding function was originally intended for short strings
2639 such as real names; it was not keeping to the 75-character limit for
2640 encoded words that the RFC imposes. It now respects the limit, and
2641 generates multiple encoded words if necessary. To be on the safe side, I
2642 have increased the buffer size for the ${rfc2047: expansion operator from
2643 1024 to 2048 bytes.
2644
063b1e99
PH
264533. It is now permitted to omit both strings after an "if" condition; if the
2646 condition is true, the result is "true". As before, when the second string
2647 is omitted, a false condition yields an empty string. This makes it less
2648 cumbersome to write custom ACL and router conditions.
2649
652e1b65
PH
265034. Failure to deliver a bounce message always caused it to be frozen, even if
2651 there was an errors_to setting on the router. The errors_to setting is now
2652 respected.
2653
6f0c9a4f
PH
265435. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2655 canonical form (fully expanded) before being placed in
2656 $sender_host_address.
2657
33397d19
PH
265836. The table in the code that translates DNS record types into text (T_A to
2659 "A" for instance) was missing entries for NS and CNAME. It is just possible
2660 that this could have caused confusion if both these types were looked up
2661 for the same domain, because the text type is used as part of Exim's
2662 per-process caching. But the chance of anyone hitting this buglet seems
2663 very small.
2664
7bb56e1f
PH
266537. The dnsdb lookup has been extended in a number of ways.
2666
2667 (1) There is a new type, "zns", which walks up the domain tree until it
2668 finds some nameserver records. It should be used with care.
2669
ea3bc19b
PH
2670 (2) There is a new type, "mxh", which is like "mx" except that it returns
2671 just the host names, not the priorities.
2672
2673 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19

2674 looked up. The behaviour when one of the lookups defers can be
2675 controlled by a keyword.
7bb56e1f 2676

7bb56e1f 2678 multiple records are returned.

2682 domain.

PH
268941. Include certificate and key file names in error message when GnuTLS fails

2700 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2701 < 0 before doing a fflush(). This bug looks as though it goes back to the
2702 introduction of TLS in release 3.20, but "sometimes" must have been rare
2703 because the tests only now provoked it.

PH
272752. Exim crashed if a remote delivery caused a very long error message to be
2728 recorded - for instance if somebody sent an entire SpamAssassin report back
2729 as a large number of 550 error lines. This bug was coincidentally fixed by
2730 increasing the size of one of Exim's internal buffers (big_buffer) that
2731 happened as part of the Exiscan merge. However, to be on the safe side, I
2732 have made the code more robust (and fixed the comments that describe what
2733 is going on).

PH
274054. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2741 patch that reportedly fixes this has been added. I am not expert enough to
2742 create a test for it. This is what the patch creator wrote:
2743
2744 "I found a little strange behaviour of ldap code when working with
2745 Windows 2003 AD Domain, where users was placed in more than one
2746 Organization Units. When I tried to give exim partial DN, the exit code
2747 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2748 But simultaneously result of request was absolutely normal ldap result,
2749 so I produce this patch..."
2750
3295e65b
PH
2751 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2752 REFERENCE, so I have modified the code to exclude the patch when that macro
2753 is not defined.

2756 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2757 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2758 leaves it alone. Component reversal etc. now happens only for IP addresses.

2772 (2) The default for smtp_banner uses $smtp_active_hostname instead
2773 of $primary_hostname.

PH
277560. The host_aton() function is supposed to be passed a string that is known
2776 to be a valid IP address. However, in the case of IPv6 addresses, it was
2777 not checking this. This is a hostage to fortune. Exim now panics and dies
2778 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2779 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2780 components; fortuitously, this particular loophole had already been fixed
2781 by change 4.50/55 above.
2782
2783 If there are any other similar loopholes, the new check in host_aton()
2784 itself should stop them being exploited. The report I received stated that
2785 data on the command line could provoke the exploit when Exim was running as
2786 exim, but did not say which command line option was involved. All I could
2787 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2788 running as the user.

2790
279161. There was a buffer overflow vulnerability in the SPA authentication code
2792 (which came originally from the Samba project). I have added a test to the
2793 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 2794 CAN-2005-0022

PH
279662. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
2797 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
2798
d95f9fdb
PH
279963. The daemon start-up calls getloadavg() while still root for those OS that
2800 need the first call to be done as root, but it missed one case: when
2801 deliver_queue_load_max is set with deliver_drop_privilege. This is
2802 necessary for the benefit of the queue runner, because there is no re-exec
2803 when deliver_drop_privilege is set.
2804
86b8287f
PH
280564. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
2806 This has been fixed.
2807
60dc5e56
PH
280865. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2809 was in use, was not putting the data itself into the right store pool;
2810 consequently, it could be overwritten for a subsequent message in the same
2811 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2812 the caching.)
2813
533244af
PH
281466. Added hosts_max_try_hardlimit to the smtp transport, default 50.
2815
a5a28604
PH
281667. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2817 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2818 the function were treating the return as a boolean value, which happened to
2819 work because 0=false and not-0=true, but is not correct code.
2820
7e634d24
PH
282168. The host_aton() function was not handling scoped IPv6 addresses (those
2822 with, for example, "%eth0" on the end) correctly.
2823
3e11c26b
PH
282469. Fixed some compiler warnings in acl.c for the bitmaps specified with
2825 negated items (that is, ~something) in unsigned ints. Some compilers
2826 apparently mutter when there is no cast.
2827
6729cf78
PH
282870. If an address verification called from an ACL failed, and did not produce a
2829 user-specific message (i.e. there was only a "system" message), nothing was
2830 put in $acl_verify_message. In this situation, it now puts the system
2831 message there.
2832
00f00ca5
PH
283371. Change 4.23/11 added synchronization checking at the start of an SMTP
2834 session; change 4.31/43 added the unwanted input to the log line - except
2835 that it did not do this in the start of session case. It now does.
2836
c9bdd01c
PH
283772. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2838 This is wrong and can cause the other end to generate a synchronization
2839 error if it is another Exim or anything else that does the synchronization
2840 check. A QUIT command is no longer sent after a timeout.
2841
d43194df
PH
284273. $host_lookup_deferred has been added, to make it easier to detect DEFERs
2843 during host lookups.
2844
fe5b5d0b
PH
284574. The defer_ok option of callout verification was not working if it was used
2846 when verifying addresses in header lines, that is, for this case:
2847
2848 verify = header_sender/callout=defer_ok
2849
76a2d7ba
PH
285075. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2851 those file descriptors could be used for SMTP connections. If anything
2852 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2853 could be sent to the SMTP client, causing chaos. The daemon now opens
2854 stdin, stdout, and stderr to /dev/null when it puts itself into the
2855 background.
2856
285776. Arrange for output from Perl's "warn" command to be written to Exim's main
2858 log by default. The user can override this with suitable Perl magic.
2859
04f7d5b9
PH
286077. The use of log_message on a "discard" ACL verb, which is supposed to add to
2861 the log message when discard triggers, was not working for the DATA ACL or
2862 for the non-SMTP ACL.
2863
bc60667e
PH
286478. Error message wording change in sieve.c.
2865
bb6e88ff
PH
286679. If smtp_accept_max_per_host was set, the number of connections could be
2867 restricted to fewer than expected, because the daemon was trying to set up
2868 a new connection before checking whether the processes handling previous
2869 connections had finished. The check for completed processes is now done
2870 earlier. On busy systems, this bug wouldn't be noticed because something
2871 else would have woken the daemon, and it would have reaped the completed
2872 process earlier.
2873
1e70f85b
PH
287480. If a message was submitted locally by a user whose login name contained one
2875 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2876 It caused a spool format error. I have fixed the spool reading code. A
2877 related problem was that the "from" clause in the Received: line became
2878 illegal because of the space(s). It is now covered by ${quote_local_part.
2879
288081. Included the latest eximstats from Steve (adds average sizes to HTML Top
2881 tables).

288382. Updated OS/Makefile-AIX as per message from Mike Meredith.

2894----------------------------------------------------
2895See the note above about the 4.44 and 4.50 releases.
2896----------------------------------------------------
2897
2898
2899Exim version 4.44
2900-----------------
2901
2902 1. Change 4.43/35 introduced a bug that caused file counts to be
2903 incorrectly computed when quota_filecount was set in an appendfile
2904 transport
2905
2906 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2907 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2908 place.
2909
2910 3. Give more explanation in the error message when the command for a transport
2911 filter fails to execute.
2912
2913 4. There are several places where Exim runs a non-Exim command in a
2914 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2915 was being done only for the command run by the queryprogram router. It is
2916 now done for all such subprocesses. The other cases are: ${run, transport
2917 filters, and the commands run by the lmtp and pipe transports.
2918
2919 5. Some older OS have a limit of 256 on the maximum number of file
2920 descriptors. Exim was using setrlimit() to set 1000 as a large value
2921 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2922 systems. I've change it so that if it can't get 1000, it tries for 256.
2923
2924 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2925 was an oversight, and furthermore, ever since the addition of extra
2926 controls (e.g. 4.43/32), the checks on when to allow different forms of
2927 "control" were broken. There should now be diagnostics for all cases when a
2928 control that does not make sense is encountered.
2929
2930 7. $recipients is now available in the predata ACL (oversight).
2931
2932 8. Tidy the search cache before the fork to do a delivery from a message
2933 received from the command line. Otherwise the child will trigger a lookup
2934 failure and thereby defer the delivery if it tries to use (for example) a
2935 cached ldap connection that the parent has called unbind on.
2936
2937 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2938 of $address_data from the recipient verification was clobbered by the
2939 sender verification.
2940
294110. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
2942 was its contents. (It was OK if the option was not defined at all.)
2943
294411. A "Completed" log line is now written for messages that are removed from
2945 the spool by the -Mrm option.
2946
294712. $host_address is now set to the target address during the checking of
2948 ignore_target_hosts.
2949
295013. When checking ignore_target_hosts for an ipliteral router, no host name was
2951 being passed; this would have caused $sender_host_name to have been used if
2952 matching the list had actually called for a host name (not very likely,
2953 since this list is usually IP addresses). A host name is now passed as
2954 "[x.x.x.x]".
2955
295614. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2957 code that specifies a non-restarting handler (typically sigaction() in
2958 modern systems) in an attempt to fix a rare and obscure crash bug.
2959
296015. Narrowed the window for a race in the daemon that could cause it to ignore
2961 SIGCHLD signals. This is not a major problem, because they are used only to
2962 wake it up if nothing else does.
2963
296416. A malformed maildirsize file could cause Exim to calculate negative values
2965 for the mailbox size or file count. Odd effects could occur as a result.
2966 The maildirsize information is now recalculated if the size or filecount
2967 end up negative.
2968
296917. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2970 support for a long time. Removed HAVE_SYS_VFS_H.
2971
ea3a6f44 297218. Updated exipick to current release from John Jetmore.
bbe902f0
PH
2973
297419. Allow an empty sender to be matched against a lookup in an address list.
2975 Previously the only cases considered were a regular expression, or an
2976 empty pattern.
2977
297820. Exim went into a mad DNS lookup loop when doing a callout where the
2979 host was specified on the transport, if the DNS lookup yielded more than
2980 one IP address.
2981
ea3a6f44
NM
298221. The RFC2047 encoding function was originally intended for short strings
2983 such as real names; it was not keeping to the 75-character limit for
2984 encoded words that the RFC imposes. It now respects the limit, and
2985 generates multiple encoded words if necessary. To be on the safe side, I
2986 have increased the buffer size for the ${rfc2047: expansion operator from
2987 1024 to 2048 bytes.
bbe902f0 2988
ea3a6f44
NM
298922. Failure to deliver a bounce message always caused it to be frozen, even if
2990 there was an errors_to setting on the router. The errors_to setting is now
2991 respected.
bbe902f0
PH
2992
299323. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2994 canonical form (fully expanded) before being placed in
2995 $sender_host_address.
2996
299724. Updated eximstats to version 1.33
2998
ea3a6f44
NM
299925. Include certificate and key file names in error message when GnuTLS fails
3000 to set them up, because the GnuTLS error message doesn't include the name
3001 of the failing file when there is a problem reading it.
bbe902f0
PH
3002
300326. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3004 As per change 25.
bbe902f0 3005
ea3a6f44
NM
300627. Reset the locale to "C" after calling embedded Perl, in case it was changed
3007 (this can affect the format of dates).
bbe902f0 3008
ea3a6f44
NM
300928. exim_tidydb, when checking for the continued existence of a message for
3010 which it has found a message-specific retry record, was not finding
3011 messages that were in split spool directories. Consequently, it was
3012 deleting retry records that should have stayed in existence.
bbe902f0
PH
3013
301429. eximstats updated to version 1.35
3015 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3016 1.35 - bugfix such that pie charts by volume are generated correctly
3017
ea3a6f44
NM
301830. The SPA authentication driver was not abandoning authentication and moving
3019 on to the next authenticator when an expansion was forced to fail,
3020 contradicting the general specification for all authenticators. Instead it
3021 was generating a temporary error. It now behaves as specified.
bbe902f0 3022
ea3a6f44
NM
302331. The default ordering of permitted cipher suites for GnuTLS was pessimal
3024 (the order specifies the preference for clients). The order is now AES256,
3025 AES128, 3DES, ARCFOUR128.
bbe902f0 3026
ea3a6f44
NM
302731. Small patch to Sieve code - explicitly set From: when generating an
3028 autoreply.
bbe902f0 3029
ea3a6f44
NM
303032. Exim crashed if a remote delivery caused a very long error message to be
3031 recorded - for instance if somebody sent an entire SpamAssassin report back
3032 as a large number of 550 error lines. This bug was coincidentally fixed by
3033 increasing the size of one of Exim's internal buffers (big_buffer) that
3034 happened as part of the Exiscan merge. However, to be on the safe side, I
3035 have made the code more robust (and fixed the comments that describe what
3036 is going on).
bbe902f0 3037
ea3a6f44
NM
303833. Some experimental protocols are using DNS PTR records for new purposes. The
3039 keys for these records are domain names, not reversed IP addresses. The
3040 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3041 leaves it alone. Component reversal etc. now happens only for IP addresses.
bbe902f0
PH
3042 CAN-2005-0021
3043
ea3a6f44
NM
304434. The host_aton() function is supposed to be passed a string that is known
3045 to be a valid IP address. However, in the case of IPv6 addresses, it was
3046 not checking this. This is a hostage to fortune. Exim now panics and dies
3047 if the condition is not met. A case was found where this could be provoked
3048 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3049 components; fortuitously, this particular loophole had already been fixed
3050 by change 4.50/55 or 4.44/33 above.
3051
3052 If there are any other similar loopholes, the new check in host_aton()
3053 itself should stop them being exploited. The report I received stated that
3054 data on the command line could provoke the exploit when Exim was running as
3055 exim, but did not say which command line option was involved. All I could
3056 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3057 running as the user.
bbe902f0

3058 CAN-2005-0021
3059
ea3a6f44
NM
306035. There was a buffer overflow vulnerability in the SPA authentication code
3061 (which came originally from the Samba project). I have added a test to the
3062 spa_base64_to_bits() function which I hope fixes it.
bbe902f0

3063 CAN-2005-0022

306536. The daemon start-up calls getloadavg() while still root for those OS that

3073 consequently, it could be overwritten for a subsequent message in the same
3074 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3075 the caching.)
bbe902f0 3076

307738. Sometimes the final signoff response after QUIT could fail to get
3078 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3079 < 0 before doing a fflush(). This bug looks as though it goes back to the
3080 introduction of TLS in release 3.20, but "sometimes" must have been rare
3081 because the tests only now provoked it.

3084Exim version 4.43
3085-----------------
3086
3087 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3088 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3089 Now it returns an integer. A number of calls were still expecting a T/F
3090 return. Fortuitously, in all cases, the tests worked in OK situations,
3091 which is the norm. However, things would have gone wrong on any write
3092 failures on the smtp file descriptor. This function is used when sending
3093 messages over SMTP and also when doing verify callouts.
3094
3095 2. When Exim is called to do synchronous delivery of a locally submitted
3096 message (the -odf or -odi options), it no longer closes stderr before doing
3097 the delivery.
3098
3099 3. Implemented the mua_wrapper option.
3100
3101 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3102
3103 5. Implemented the functions header_remove(), header_testname(),
3104 header_add_at_position(), and receive_remove_recipient(), and exported them
3105 to local_scan().
3106
3107 6. If an ACL "warn" statement specified the addition of headers, Exim already
3108 inserted X-ACL-Warn: at the start if there was no header name. However, it
3109 was not making this test for the second and subsequent header lines if
3110 there were newlines in the string. This meant that an invalid header could
3111 be inserted if Exim was badly configured.
3112
3113 7. Allow an ACL "warn" statement to add header lines at the start or after all
3114 the Received: headers, as well as at the end.
3115
3116 8. Added the rcpt_4xx retry error code.
3117
3118 9. Added postmaster_mailfrom=xxx to callout verification option.
3119
312010. Added mailfrom=xxxx to the callout verification option, for verify=
3121 header_sender only.
3122
312311. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3124 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3125
312612. Inserted some casts to stop certain compilers warning when using pointer
3127 differences as field lengths or precisions in printf-type calls (mostly
3128 affecting debugging statements).
3129
313013. Added optional readline() support for -be (dynamically loaded).
3131
313214. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3133 same clock tick as a message's arrival, so that its received time was the
3134 same as the "first fail" time on the retry record, and that message
3135 remained on the queue past the ultimate address timeout, every queue runner
3136 would try a delivery (because it was past the ultimate address timeout) but
3137 after another failure, the ultimate address timeout, which should have then
3138 bounced the address, did not kick in. This was a "< instead of <=" error;
3139 in most cases the first failure would have been in the next clock tick
3140 after the received time, and all would be well.
3141
314215. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3143 being recognized when the domain list was tested by the match_domain
3144 condition in an expansion string.
3145
314616. Added the ${str2b64: operator.
3147
314817. Exim was always calling setrlimit() to set a large limit for the number of
3149 processes, without checking whether the existing limit was already
3150 adequate. (It did check for the limit on file descriptors.) Furthermore,
3151 errors from getrlimit() and setrlimit() were being ignored. Now they are
3152 logged to the main and panic logs, but Exim does carry on, to try to do its
3153 job under whatever limits there are.
3154
315518. Imported PCRE 5.0.
3156
315719. Trivial typo in log message " temporarily refused connection" (the leading
3158 space).
3159
316020. If the log selector return_path_on_delivery was set and an address was
3161 redirected to /dev/null, the delivery process crashed because it assumed
3162 that a return path would always be set for a "successful" delivery. In this
3163 case, the whole delivery is bypassed as an optimization, and therefore no
3164 return path is set.
3165
316621. Internal re-arrangement: the function for sending a challenge and reading
3167 a response while authentication was assuming a zero-terminated challenge
3168 string. It's now changed to take a pointer and a length, to allow for
3169 binary data in such strings.
3170
317122. Added the cyrus_sasl authenticator (code supplied by MBM).
3172
317323. Exim was not respecting finduser_retries when seeking the login of the
3174 uid under which it was called; it was always trying 10 times. (The default
3175 setting of finduser_retries is zero.) Also, it was sleeping after the final
3176 failure, which is pointless.
3177
317824. Implemented tls_on_connect_ports.
3179
318025. Implemented acl_smtp_predata.
3181
318226. If the domain in control=submission is set empty, Exim assumes that the
3183 authenticated id is a complete email address when it generates From: or
3184 Sender: header lines.
3185
318627. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3187 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3188 chown and chgrp in /bin and hostname in /usr/bin.
3189
319028. Exim was keeping the "process log" file open after each use, just as it
3191 does for the main log. This opens the possibility of it remaining open for
3192 long periods when the USR1 signal hits a daemon. Occasional processlog
3193 errors were reported, that could have been caused by this. Anyway, it seems
3194 much more sensible not to leave this file open at all, so that is what now
3195 happens.
3196
319729. The long-running daemon process does not normally write to the log once it
3198 has entered its main loop, and it closes the log before doing so. This is
3199 so that log files can straightforwardly be renamed and moved. However,
3200 there are a couple of unusual error situations where the daemon does write
3201 log entries, and I had neglected to close the log afterwards.
3202
320330. The text of an SMTP error response that was received during a remote
3204 delivery was being truncated at 512 bytes. This is too short for some of
3205 the long messages that one sometimes sees. I've increased the limit to
3206 1024.
3207
320831. It is now possible to make retry rules that apply only when a message has a
3209 specific sender, in particular, an empty sender.
3210
321132. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3212 it possible to be selective about when SMTP synchronization is enforced.
3213
321433. Added "control = caseful_local_part" and "control = "caselower_local_part".
3215
321632. Implemented hosts_connection_nolog.
3217
321833. Added an ACL for QUIT.
3219
322034. Setting "delay_warning=" to disable warnings was not working; it gave a
3221 syntax error.
3222
322335. Added mailbox_size and mailbox_filecount to appendfile.
3224
322536. Added control = no_multiline_responses to ACLs.
3226
322737. There was a bug in the logic of the code that waits for the clock to tick
3228 in the case where the clock went backwards by a substantial amount such
3229 that the microsecond fraction of "now" was more than the microsecond
3230 fraction of "then" (but the whole seconds number was less).
3231
323238. Added support for the libradius Radius client library this is found on
3233 FreeBSD (previously only the radiusclient library was supported).
3234
3235
3236Exim version 4.42
3237-----------------
3238
3239 1. When certain lookups returned multiple values in the form name=value, the
3240 quoting of the values was not always being done properly. Specifically:
3241 (a) If the value started with a double quote, but contained no whitespace,
3242 it was not quoted.
3243 (b) If the value contained whitespace other than a space character (i.e.
3244 tabs or newlines or carriage returns) it was not quoted.
3245 This fix has been applied to the mysql and pgsql lookups by writing a
3246 separate quoting function and calling it from the lookup code. The fix
3247 should probably also be applied to nisplus, ibase and oracle lookups, but
3248 since I cannot test any of those, I have not disturbed their existing code.
3249
3250 2. A hit in the callout cache for a specific address caused a log line with no
3251 reason for rejecting RCPT. Now it says "Previous (cached) callout
3252 verification failure".
3253
3254 3. There was an off-by-one bug in the queryprogram router. An over-long
3255 return line was truncated at 256 instead of 255 characters, thereby
3256 overflowing its buffer with the terminating zero. As well as fixing this, I
3257 have increased the buffer size to 1024 (and made a note to document this).
3258
3259 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3260 when Exim is waiting for an SMTP response from a remote server, Exim
3261 restarts its select() call on the socket, thereby resetting its timeout.
3262 This is not a problem when such interrupts are rare. Somebody set up a cron
3263 job to run exiwhat every 2 minutes, which is less than the normal select()
3264 timeout (5 or 10 minutes). This meant that the select() timeout never
3265 kicked in because it was always reset. I have fixed this by comparing the
3266 time when an interrupt arrives with the time at the start of the first call
3267 to select(). If more time than the timeout has elapsed, the interrupt is
3268 treated as a timeout.
3269
3270 5. Some internal re-factoring in preparation for the addition of Sieve
3271 extensions (by MH). In particular, the "personal" test is moved to a
3272 separate function, and given an option for scanning Cc: and Bcc: (which is
3273 not set for Exim filters).
3274
3275 6. When Exim created an email address using the login of the caller as the
3276 local part (e.g. when creating a From: or Sender: header line), it was not
3277 quoting the local part when it contained special characters such as @.
3278
3279 7. Installed new OpenBSD configuration files.
3280
3281 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3282 try to make them clearer.
3283
3284 9. Callout options, other than the timeout value, were being ignored when
3285 verifying sender addresses in header lines. For example, when using
3286
3287 verify = header_sender/callout=no_cache
3288
3289 the cache was (incorrectly) being used.
3290
329110. Added a missing instance of ${EXE} to the exim_install script; this affects
3292 only the Cygwin environment.
3293
329411. When return_path_on_delivery was set as a log selector, if different remote
3295 addresses in the same message used different return paths and parallel
3296 remote delivery occurred, the wrong values would sometimes be logged.
3297 (Whenever a remote delivery process finished, the return path value from
3298 the most recently started remote delivery process was logged.)
3299
330012. RFC 3848 specifies standard names for the "with" phrase in Received: header
3301 lines when AUTH and/or TLS are in use. This is the "received protocol"
3302 field. Exim used to use "asmtp" for authenticated SMTP, without any
3303 indication (in the protocol name) for TLS use. Now it follows the RFC and
3304 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3305 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3306 names appear in log lines as well as in Received: header lines.
3307
330813. Installed MH's patches for Sieve to add the "copy" and "vacation"
3309 extensions, and comparison tests, and to fix some bugs.
3310
331114. Changes to the "personal" filter test:
3312
3313 (1) The test was buggy in that it was just doing the equivalent of
3314 "contains" tests on header lines. For example, if a user's address was
3315 anne@some.where, the "personal" test would incorrectly be true for
3316
3317 To: susanne@some.where
3318
3319 This test is now done by extracting each address from the header in turn,
3320 and checking the entire address. Other tests that are part of "personal"
3321 are now done using regular expressions (for example, to check local parts
3322 of addresses in From: header lines).
3323
3324 (2) The list of non-personal local parts in From: addresses has been
3325 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3326 taken from the Sieve specification recommendations.
3327
3328 (3) If the message contains any header line starting with "List-" it is
3329 treated as non-personal.
3330
3331 (4) The test for "circular" in the Subject: header line has been removed
3332 because it now seems ill-conceived.
3333
333415. Minor typos in src/EDITME comments corrected.
3335
333616. Installed latest exipick from John Jetmore.
3337
333817. If headers_add on a router specified a text string that was too long for
3339 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3340 of string_sprintf() is now avoided.
3341
334218. $message_body_size was not set (it was always zero) when running the DATA
3343 ACL and the local_scan() function.
3344
334519. For the "mail" command in an Exim filter, no default was being set for
3346 the once_repeat time, causing a random time value to be used if "once" was
3347 specified. (If the value happened to be <= 0, no repeat happened.) The
3348 default is now 0s, meaning "never repeat". The "vacation" command was OK
3349 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3350 (I found it when inspecting the code).
3351
335220. There is now an overall timeout for performing a callout verification. It
3353 defaults to 4 times the callout timeout, which applies to individual SMTP
3354 commands during the callout. The overall timeout applies when there is more
3355 than one host that can be tried. The timeout is checked before trying the
3356 next host. This prevents very long delays if there are a large number of
3357 hosts and all are timing out (e.g. when the network connections are timing
3358 out). The value of the overall timeout can be changed by specifying an
3359 additional sub-option for "callout", called "maxwait". For example:
3360
3361 verify = sender/callout=5s,maxwait=20s
3362
336321. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3364 to the end before writing, but this should make it even safer).
3365
336622. Exim was forgetting that it had advertised PIPELINING for the second and
3367 subsequent messages on an SMTP connection. It was also not resetting its
3368 memory on STARTTLS and an internal HELO.
3369
337023. When Exim logs an SMTP synchronization error within a session, it now
3371 records whether PIPELINING has been advertised or not.
3372
337324. Added 3 instances of "(long int)" casts to time_t variables that were being
3374 formatted using %ld, because on OpenBSD (and perhaps others), time_t is int
3375 rather than long int.
3376
337725. Installed the latest Cygwin configuration files from the Cygwin maintainer.
3378
337926. Added the never_mail option to autoreply.
3380
3381
3382Exim version 4.41
3383-----------------
3384
3385 1. A reorganization of the code in order to implement 4.40/8 caused a daemon
3386 crash if the getsockname() call failed; this can happen if a connection is
3387 closed very soon after it is established. The problem was simply in the
3388 order in which certain operations were done, causing Exim to try to write
3389 to the SMTP stream before it had set up the file descriptor. The bug has
3390 been fixed by making things happen in the correct order.
3391
3392
3393Exim version 4.40
3394-----------------
3395
3396 1. If "drop" was used in a DATA ACL, the SMTP output buffer was not flushed
3397 before the connection was closed, thus losing the rejection response.
3398
3399 2. Commented out the definition of SOCKLEN_T in os.h-SunOS5. It is needed for
3400 some early Solaris releases, but causes trouble in current releases where
3401 socklen_t is defined.
3402
3403 3. When std{in,out,err} are closed, re-open them to /dev/null so that they
3404 always exist.
3405
3406 4. Minor refactoring of os.c-Linux to avoid compiler warning when IPv6 is not
3407 configured.
3408
3409 5. Refactoring in expand.c to improve memory usage. Pre-allocate a block so
3410 that releasing the top of it at the end releases what was used for sub-
3411 expansions (unless the block got too big). However, discard this block if
3412 the first thing is a variable or header, so that we can use its block when
3413 it is dynamic (useful for very large $message_headers, for example).
3414
3415 6. Lookups now cache *every* query, not just the most recent. A new, separate
3416 store pool is used for this. It can be recovered when all lookup caches are
3417 flushed. Lookups now release memory at the end of their result strings.
3418 This has involved some general refactoring of the lookup sources.
3419
3420 7. Some code has been added to the store_xxx() functions to reduce the amount
3421 of flapping under certain conditions.
3422
3423 8. log_incoming_interface used to affect only the <= reception log lines. Now
3424 it causes the local interface and port to be added to several more SMTP log
3425 lines, for example "SMTP connection from", and rejection lines.
3426
3427 9. The Sieve author supplied some patches for the doc/README.SIEVE file.
3428
342910. Added a conditional definition of _BSD_SOCKLEN_T to os.h-Darwin.
3430
343111. If $host_data was set by virtue of a hosts lookup in an ACL, its value
3432 could be overwritten at the end of the current message (or the start of a
3433 new message if it was set in a HELO ACL). The value is now preserved for
3434 the duration of the SMTP connection.
3435
343612. If a transport had a headers_rewrite setting, and a matching header line
3437 contained an unqualified address, that address was qualified, even if it
3438 did not match any rewriting rules. The underlying bug was that the values
3439 of the flags that permit the existence of unqualified sender and recipient
3440 addresses in header lines (set by {sender,recipient}_unqualified_hosts for
3441 non-local messages, and by -bnq for local messages) were not being
3442 preserved with the message after it was received.
3443
344413. When Exim was logging an SMTP synchronization error, it could sometimes log
3445 "next input=" as part of the text comprising the host identity instead of
3446 the correct text. The code was using the same buffer for two different
3447 strings. However, depending on which order the printing function evaluated
3448 its arguments, the bug did not always show up. Under Linux, for example, my
3449 test suite worked just fine.
3450
345114. Exigrep contained a use of Perl's "our" scoping after change 4.31/70. This
3452 doesn't work with some older versions of Perl. It has been changed to "my",
3453 which in any case is probably the better facility to use.
3454
345515. A really picky compiler found some instances of statements for creating
3456 error messages that either had too many or two few arguments for the format
3457 string.
3458
