TK
347TK/01 Add preliminary DKIM support. Currently requires a forked version of
348 ALT-N's libdkim that I have put here:
349 http://duncanthrax.net/exim-experimental/
350
351 Note to Michael Haardt: I had to rename some vars in sieve.c. They
352 were called 'true' and it seems that C99 defines that as a reserved
353 keyword to be used with 'bool' variable types. That means you could
354 not include C99-style headers which use bools without triggering
355 build errors in sieve.c.

370Exim version 4.68
371-----------------
372
373PH/01 Another patch from the Sieve maintainer.
374
6a3bceb1
PH
375PH/02 When an IPv6 address is converted to a string for single-key lookup
376 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
377 dots are used instead of colons so that keys in lsearch files need not
378 contain colons. This was done some time before quoting was made available
379 in lsearch files. However, iplsearch files do require colons in IPv6 keys
380 (notated using the quote facility) so as to distinguish them from IPv4
381 keys. This meant that lookups for IP addresses in host lists did not work
382 for iplsearch lookups.
383
384 This has been fixed by arranging for IPv6 addresses to be expressed with
385 colons if the lookup type is iplsearch. This is not incompatible, because
386 previously such lookups could never work.
387
388 The situation is now rather anomolous, since one *can* have colons in

395MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
396 conversion specification without a maximum field width, thereby enabling
397 a rogue spamd server to cause a buffer overflow. While nobody in their
398 right mind would setup Exim to query an untrusted spamd server, an
399 attacker that gains access to a server running spamd could potentially
400 exploit this vulnerability to run arbitrary code as the Exim user.

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

673 the response to the final '.' that terminates a message, but only in the
674 case where the client has not sent further data following the '.'
675 (unfortunately, this is allowed). However, in many cases there won't be
676 any further data because there won't be any more messages to send. A call
677 to select() can be used: if it shows that the input is "ready", there is
678 either input waiting, or the socket has been closed. An attempt to read
679 the next input character can distinguish the two cases. Previously, Exim
58eb016e 680 would have sent an OK response which the client would never have see.

691PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
692 fixed by 4.65/MH/01 (is this a record?) are fixed:
693
694 (i) An empty string was always treated as zero by the numeric comparison
695 operators. This behaviour has been restored.
696
697 (ii) It is documented that the numeric comparison operators always treat
698 their arguments as decimal numbers. This was broken in that numbers
699 starting with 0 were being interpreted as octal.
700
701 While fixing these problems I realized that there was another issue that
702 hadn't been noticed. Values of message_size_limit (both the global option
703 and the transport option) were treated as octal if they started with 0.
704 The documentation was vague. These values are now always treated as
705 decimal, and I will make that clear in the documentation.

722 large number of recipients for a single message is ridiculous

724 rather than extend the field.

2b1c6e3a
PH
749PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
750 callout verification, Exim cached a "reject" for the entire domain. This
751 is correct for most verifications, but it is not correct for a recipient
752 verification with use_sender or use_postmaster set, because in that case
753 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
754 case of MAIL FROM:<> rejection from other early rejections (e.g.
755 rejection of HELO). When verifying a recipient using a non-null MAIL
756 address, the cache is ignored if it shows MAIL FROM:<> rejection.
757 Whatever the result of the callout, the value of the domain cache is
758 left unchanged (for any other kind of callout, getting as far as trying
759 RCPT means that the domain itself is ok).

796 callout (which could be using a different interface). This has been
797 changed to use the value of the helo_data option from the smtp transport
798 instead - this is what is used when a message is actually being sent. If
799 there is no remote transport (possible with a router that sets up host
800 addresses), $smtp_active_hostname is used.

14aa5a05 802PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 803 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
804 (a) The code assumed that strncpy() returns a negative number on buffer
805 overflow, which isn't the case. Replaced with Exim's string_format()
806 function.
807 (b) There were several signed/unsigned issues. I just did the minimum
808 hacking in of casts. There is scope for a larger refactoring.
809 (c) The code used strcasecmp() which is not a standard C function.
810 Replaced with Exim's strcmpic() function.
811 (d) The code set only $1; it now sets $auth1 as well.
812 (e) A simple test gave the error "authentication client didn't specify
813 service in request". It would seem that Dovecot has changed its
814 interface. Fortunately there's a specification; I followed it and
815 changed what the client sends and it appears to be working now.

PH
820PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
821 address A is aliased to B and C, where B exists and C does not. Without
822 -v the output is "A verified" because verification stops after a
823 successful redirection if more than one address is generated. However,
824 with -v the child addresses are also verified. Exim was outputting "A
825 failed to verify" and then showing the successful verification for C,
826 with its parentage. It now outputs "B failed to verify", showing B's
827 parentage before showing the successful verification of C.

829PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
830 look up a TXT record in a specific list after matching in a combined
831 list.
832
322050c2
PH
833PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
834 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
835 they consult the DNS. I had assumed they would set it the way they
836 wanted; and indeed my experiments on Linux seem to show that in some
837 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
838 To be on the safe side, however, I have now made the interface to
839 host_find_byname() similar to host_find_bydns(), with an argument
840 containing the DNS resolver options. The host_find_byname() function now
841 sets these options at its start, just as host_find_bydns() does. The smtp
842 transport options dns_qualify_single and dns_search_parents are passed to
843 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
844 of host_find_byname() use the default settings of RES_DEFNAMES
845 (qualify_single) but not RES_DNSRCH (search_parents).
846

PH
847PH/17 Applied (a modified version of) Nico Erfurth's patch to make
848 spool_read_header() do less string testing, by means of a preliminary
849 switch on the second character of optional "-foo" lines. (This is
850 overdue, caused by the large number of possibilities that now exist.
851 Originally there were few.) While I was there, I also converted the
852 str(n)cmp tests so they don't re-test the leading "-" and the first
853 character, in the hope this might squeeze out yet more improvement.
854

PH
855PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
856 flag allowing group syntax was set by the header_syntax check but not
857 turned off, possible causing trouble later; (2) The flag was not being
858 set at all for the header_verify test, causing "group"-style headers to
859 be rejected. I have now set it in this case, and also caused header_
860 verify to ignore an empty address taken from a group. While doing this, I
861 came across some other cases where the code for allowing group syntax
862 while scanning a header line wasn't quite right (mostly, not resetting
863 the flag correctly in the right place). These bugs could have caused
864 trouble for malformed header lines. I hope it is now all correct.
865
602e59e5
PH
866PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
867 with the "reply" argument non-NULL. The code, however (which originally
868 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
869 but it didn't always do it. This confused somebody who was copying the
870 code for some other use. I have removed all the tests.
871
411ef850
PH
872PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
873 feature that was used to support insecure browsers during the U.S. crypto
874 embargo. It requires special client support, and Exim is probably the
875 only MTA that supported it -- and would never use it because real RSA is
876 always available. This code has been removed, because it had the bad
877 effect of slowing Exim down by computing (never used) parameters for the
878 RSA_EXPORT functionality.
879
7befa435
PH
880PH/21 On the advice of Timo Sirainen, added a check to the dovecot
881 authenticator to fail if there's a tab character in the incoming data
882 (there should never be unless someone is messing about, as it's supposed
883 to be base64-encoded). Also added, on Timo's advice, the "secured" option
884 if the connection is using TLS or if the remote IP is the same as the
885 local IP, and the "valid-client-cert option" if a client certificate has
886 been verified.

PH
917
918PH/30 Exim was sometimes attempting to deliver messages that had suffered
919 address errors (4xx response to RCPT) over the same connection as other
920 messages routed to the same hosts. Such deliveries are always "forced",
921 so retry times are not inspected. This resulted in far too many retries
922 for the affected addresses. The effect occurred only when there were more
923 hosts than the hosts_max_try setting in the smtp transport when it had
924 the 4xx errors. Those hosts that it had tried were not added to the list
925 of hosts for which the message was waiting, so if all were tried, there
926 was no problem. Two fixes have been applied:
927
928 (i) If there are any address or message errors in an SMTP delivery, none
929 of the hosts (tried or untried) are now added to the list of hosts
930 for which the message is waiting, so the message should not be a
931 candidate for sending over the same connection that was used for a
932 successful delivery of some other message. This seems entirely
933 reasonable: after all the message is NOT "waiting for some host".
934 This is so "obvious" that I'm not sure why it wasn't done
935 previously. Hope I haven't missed anything, but it can't do any
936 harm, as the worst effect is to miss an optimization.
937
938 (ii) If, despite (i), such a delivery is accidentally attempted, the
939 routing retry time is respected, so at least it doesn't keep
940 hammering the server.

PH
955PH/35 The error "getsockname() failed: connection reset by peer" was being
956 written to the panic log as well as the main log, but it isn't really
957 panic-worthy as it just means the connection died rather early on. I have
958 removed the panic log writing for the ECONNRESET error when getsockname()
959 fails.
960
48c7f9e2
PH
961PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
962 runs only) independently of the message's sender address. This meant
963 that, if the 4xx error was in fact related to the sender, a different
964 message to the same recipient with a different sender could confuse
965 things. In particualar, this can happen when sending to a greylisting
966 server, but other circumstances could also provoke similar problems.
967 I have changed the default so that the retry time for these errors is now
968 based a combination of the sender and recipient addresses. This change
969 can be overridden by setting address_retry_include_sender=false in the
970 smtp transport.

1238PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1239 "Deny" causes Exim to reject the incoming connection with a 554 error.
1240 Unfortunately, if there is a major crisis, such as a disk failure,
1241 tcp-wrappers gives "deny", whereas what one would like would be some
1242 kind of temporary error. A kludge has been added to help with this.
1243 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1244 554 error is used if errno is still zero or contains ENOENT (which occurs
1245 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1246 451 error is used.

1271 used only to exclude .Trash (or whatever) when the size of the mailbox
1272 was calculated. There was no check that a delivery was happening into an

1282PH/01 The code for finding all the local interface addresses on a FreeBSD
1283 system running IPv6 was broken. This may well have applied to all BSD
1284 systems, as well as to others that have similar system calls. The broken
1285 code found IPv4 interfaces correctly, but gave incorrect values for the
1286 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1287 that it would not match correctly against @[] and not recognize the IPv6
1288 addresses as local.

1331 autoreply, Exim could try to deliver to a non-existent relative file

1353
1354 (a) Failures to set uid/gid, the current directory, or a process leader
1355 in a subprocess such as that created by queryprogram now generate
1356 suitable debugging ouput when -d is set.
1357

1360 the subprocess without attempting to change uid/gid.

1366 additional section of a DNS packet that returns MX or SRV records.
1367 Instead, it always explicitly searches for A/AAAA records. This avoids
1368 major problems that occur when a DNS server includes only records of one
1369 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1370 fixed another bug: if SRV records were looked up and the corresponding
1371 address records were *not* found in the additional section, the port
1372 values from the SRV records were lost.

1374PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1382PH/19 When calculating a retry time, Exim used to measure the "time since
1383 failure" by looking at the "first failed" field in the retry record. Now
1384 it does not use this if it is later than than the arrival time of the
1385 message. Instead it uses the arrival time. This makes for better
1386 behaviour in cases where some deliveries succeed, thus re-setting the
1387 "first failed" field. An example is a quota failure for a huge message
1388 when small messages continue to be delivered. Without this change, the
1389 "time since failure" will always be short, possible causing more frequent
1390 delivery attempts for the huge message than are intended.

PH
1487PH/42 The content-scanning code uses fopen() to create files in which to put
1488 message data. Previously it was not paying any attention to the mode of
1489 the files. Exim runs with umask(0) because the rest of the code creates
1490 files with open(), and sets the required mode explicitly. Thus, these
1491 files were ending up world-writeable. This was not a big issue, because,
1492 being within the spool directory, they were not world-accessible. I have
1493 created a function called modefopen, which takes an additional mode
1494 argument. It sets umask(777), creates the file, chmods it to the required
1495 mode, then resets the umask. All the relevant calls to fopen() in the

1533
1534 (i) Exim was not creating retry information for temporary errors given
1535 for individual recipients after the DATA command when the smtp transport
1536 was used in LMTP mode. This meant that they could be retried too
1537 frequently, and not timed out correctly.
1538
1539 (ii) Exim was setting the flag that allows error details to be returned
1540 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1541 recipients that were returned after the DATA command.
1542
1543PH/53 This is related to PH/52, but is more general: for any failing address,
1544 when detailed error information was permitted to be returned to the

1617PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1618 function verify_get_ident() calls ip_connect() to connect a socket, but
1619 if the "connect()" function timed out, ip_connect() used to close the
1620 socket. However, verify_get_ident() also closes the socket later, and in
1621 between Exim writes to the log, which may get opened at this point. When
1622 the socket was closed in ip_connect(), the log could get the same file
1623 descriptor number as the socket. This naturally causes chaos. The fix is
1624 not to close the socket in ip_connect(); the socket should be closed by
1625 the function that creates it. There was only one place in the code where
1626 this was missing, in the iplookup router, which I don't think anybody now
1627 uses, but I've fixed it anyway.

1650
1651 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1652 string.
1653
1654 (3) Reset the variables that are obtained from the first argument of
1655 ${prvscheck and used in the second argument before leaving the code,
1656 because their memory is reclaimed, so using them afterwards may do
1657 silly things.
1658
1659 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1660 one (it's much easier than Tom thought :-).
1661
1662 (5) Because of (4), we can now allow for the use of $prvscheck_result

1678 may be more than one such address. If so, they are comma-separated, like

1683PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1684 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1685 not being looked up in the rDNS to get a host name, Exim was showing the
1686 IP address twice in Received: lines, even though the IP addresses were
1687 identical. For example:
1688
1689 Received: from [1.2.3.4] (helo=[1.2.3.4])
1690
1691 However, if the real host name was known, it was omitting the HELO data
1692 if it matched the actual IP address. This has been tidied up so that it
1693 doesn't show the same IP address twice.

1719PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

1721
1722 Auto-submitted: auto-generated
1723
1724 in the messages that it generates (bounce messages and others, such as
1725 warnings). In the case of bounce messages for non-SMTP mesages, there was
1726 also a typo: it was using "Auto_submitted" (underscore instead of
1727 hyphen). Since every message generated by Exim is necessarily in response
1728 to another message, thes have all been changed to:
1729
1730 Auto-Submitted: auto-replied
1731
1732 in accordance with these statements in the RFC:
1733
1734 The auto-replied keyword:
1735
1736 - SHOULD be used on messages sent in direct response to another
1737 message by an automatic process,
1738
1739 - MUST NOT be used on manually-generated messages,

1741 - MAY be used on Delivery Status Notifications (DSNs) and Message
1742 Disposition Notifications (MDNs),

1782PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1783 canonical form (as documented). However, after a host name lookup from
1784 the IP address, check_host() was doing a simple string comparison with
1785 addresses acquired from the DNS when checking that the found name did
1786 have the original IP as one of its addresses. Since any found IPv6
1787 addresses are likely to be in abbreviated form, the comparison could
1788 fail. Luckily, there already exists a function for doing the comparison
1789 by converting both addresses to binary, so now that is used instead of
1790 the text comparison.

2088 with the definition in sysexits.h (which is #included earlier).
2089 Fortunately, Exim does not actually use EX_OK. The code used to try to
2090 preserve the sysexits.h value, by assumimg that macro definitions were
2091 scanned for macro replacements. I have been disabused of this notion,

2099 doesn't have to be particularly precise.

2308PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2309 that changes the way the GnuTLS parameters are stored in the cache file.
2310 The new format can be generated externally. For backward compatibility,
2311 if the data in the cache doesn't make sense, Exim assumes it has read an
2312 old-format file, and it generates new data and writes a new file. This
2313 means that you can't go back to an older release without removing the
2314 file.
2315
2316PH/03 A redirect router that has both "unseen" and "one_time" set does not
2317 work if there are any delivery delays because "one_time" forces the
2318 parent to be marked "delivered", so its unseen clone is never tried
2319 again. For this reason, Exim now forbids the simultaneous setting of
2320 these two options.
2321
2322PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2323 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2324 entry if you want to know the details. The fix, however, neglected to
2325 consider the case when local delivery batching is involved. The test for
2326 "previously delivered" was not happening when checking to see if an
2327 address could be batched with a previous (undelivered) one; under
2328 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2329 address.

2334PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2335 header_syntax) but Exim was just ignoring anything given after a slash.
2336 In particular, this caused confusion with an attempt to use "verify =
2337 reverse_host_lookup/defer_ok". An error is now given when options are
2338 supplied for verify items that do not have them. (Maybe reverse_host_
2339 lookup should have a defer_ok option, but that's a different point.)
2340
2341PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2391PH/19 When an Exim process that is running as root has to create an Exim log
2392 file, it does so in a subprocess that runs as exim:exim so as to get the
2393 ownership right at creation (otherwise, other Exim processes might see
2394 the file with the wrong ownership). There was no test for failure of this
2395 fork() call, which would lead to the process getting stuck as it waited
2396 for a non-existent subprocess. Forks do occasionally fail when resources
2397 run out. I reviewed all the other calls to fork(); they all seem to check
2398 for failure.

2400PH/20 When checking for unexpected SMTP input at connect time (before writing
2401 the banner), Exim was not dealing correctly with a non-positive return
2402 from the read() function. If the client had disconnected by this time,
2403 the result was a log entry for a synchronization error with an empty
2404 string after "input=" when read() returned zero. If read() returned -1
2405 (an event I could not check), uninitialized data bytes were printed.

PH
2417PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2418 hadn't been configured. The fix is from Juergen Kreileder, who
2419 understands it better than I do:
2420
2421 "Here's what I see happening with three configured cyrus_sasl
2422 authenticators configured (plain, login, cram-md5):
2423
2424 On startup auth_cyrus_sasl_init() gets called for each of these.
2425 This means three calls to sasl_listmech() without a specified mech_list.
2426 => SASL tests which mechs of all available mechs actually work
2427 => three warnings about OTP not working
2428 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2429
2430 With the patch, sasl_listmech() also gets called three times. But now
2431 SASL's mech_list option is set to the server_mech specified in the the
2432 authenticator. Or in other words, the answer from sasl_listmech()
2433 gets limited to just the mech you're testing for (which is different
2434 for each call.)
2435 => the return list contains just 'plain' or 'login', 'cram-md5' or
2436 nothing depending on the value of ob->server_mech.
2437
2438 I've just tested the patch: Authentication still works fine,
2439 unavailable mechs specified in the exim configuration are still
2440 caught, and the auth.log warnings about OTP are gone."

PH
2504PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2505 the grounds that routing the same address twice would always produce the
2506 same answer. This might have been true once, but it is certainly no
2507 longer true now. Routing a child address may depend on the previous
2508 routing that produced that child. Some complicated redirection strategies
2509 went wrong when messages had multiple recipients, and made Exim's
2510 behaviour dependent on the order in which the addresses were given.
2511
2512 I have moved the duplicate checking until after the routing is complete.
2513 Exim scans the addresses that are assigned to local and remote
2514 transports, and removes any duplicates. This means that more work will be
2515 done, as duplicates will always all be routed, but duplicates are
2516 presumably rare, so I don't expect this is of any significance.
2517
2518 For deliveries to pipes, files, and autoreplies, the duplicate checking
2519 still happens during the routing process, since they are not going to be
2520 routed further.

2565 consistency with the overall process timeout, these timeouts are now
2566 treated as errors, giving rise to delivery failures by default. However,
2567 there is now a new Boolean option for the pipe transport called
2568 timeout_defer, which, if set TRUE, converts the failures into defers for
2569 both kinds of timeout. A transport filter timeout is now identified in

2579A note about Exim versions 4.44 and 4.50
2580----------------------------------------
2581
2582Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2583changes of various kinds. As a consequence, a big documentation update was
2584needed. This delayed the release for rather longer than seemed good, especially
2585in the light of a couple of (minor) security issues. Therefore, the changes
2586that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2587release. So 4.44 and 4.50 are in effect two different branches that both start
2588from 4.43.
2589
2590I have left the 4.50 change log unchanged; it contains all the changes since
25914.43. The change log for 4.44 is below; many of its items are identical to
2592those for 4.50. This seems to be the most sensible way to preserve the
2593historical information.

2611 5. There are several places where Exim runs a non-Exim command in a
2612 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2613 was being done only for the command run by the queryprogram router. It is
2614 now done for all such subprocesses. The other cases are: ${run, transport
2615 filters, and the commands run by the lmtp and pipe transports.

2619 7. Some older OS have a limit of 256 on the maximum number of file
2620 descriptors. Exim was using setrlimit() to set 1000 as a large value
2621 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2622 systems. I've change it so that if it can't get 1000, it tries for 256.

2626 controls (e.g. 4.43/32), the checks on when to allow different forms of
2627 "control" were broken. There should now be diagnostics for all cases when a
2628 control that does not make sense is encountered.

266922. $host_address is now set to the target address during the checking of
2670 ignore_target_hosts.
2671
267223. When checking ignore_target_hosts for an ipliteral router, no host name was
2673 being passed; this would have caused $sender_host_name to have been used if
2674 matching the list had actually called for a host name (not very likely,
2675 since this list is usually IP addresses). A host name is now passed as
2676 "[x.x.x.x]".
2677

PH
267824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2679 code that specifies a non-restarting handler (typically sigaction() in
2680 modern systems) in an attempt to fix a rare and obscure crash bug.
2681
268225. Narrowed the window for a race in the daemon that could cause it to ignore
2683 SIGCHLD signals. This is not a major problem, because they are used only to
2684 wake it up if nothing else does.

PH
269629. In an address list, if the pattern was not a regular expression, an empty
2697 subject address (from a bounce message) matched only if the pattern was an
2698 empty string. Non-empty patterns were not even tested. This was the wrong
2699 because it is perfectly reasonable to use an empty address as part of a
2700 database query. An empty address is now tested by patterns that are
2701 lookups. However, all the other forms of pattern expect the subject to
2702 contain a local part and a domain, and therefore, for them, an empty
2703 address still always fails if the pattern is not itself empty.
2704
d8ef3577
PH
270530. Exim went into a mad DNS loop when attempting to do a callout where the
2706 host was specified on an smtp transport, and looking it up yielded more
2707 than one IP address.

5cb8cbc6
PH
270931. Re-factored the code for checking spool and log partition space into a
2710 function that finds that data and another that does the check. The former
2711 is then used to implement four new variables: $spool_space, $log_space,
2712 $spool_inodes, and $log_inodes.
2713

PH
271432. The RFC2047 encoding function was originally intended for short strings
2715 such as real names; it was not keeping to the 75-character limit for
2716 encoded words that the RFC imposes. It now respects the limit, and
2717 generates multiple encoded words if necessary. To be on the safe side, I
2718 have increased the buffer size for the ${rfc2047: expansion operator from
2719 1024 to 2048 bytes.
2720
063b1e99
PH
272133. It is now permitted to omit both strings after an "if" condition; if the
2722 condition is true, the result is "true". As before, when the second string
2723 is omitted, a false condition yields an empty string. This makes it less
2724 cumbersome to write custom ACL and router conditions.
2725
652e1b65
PH
272634. Failure to deliver a bounce message always caused it to be frozen, even if
2727 there was an errors_to setting on the router. The errors_to setting is now
2728 respected.

PH
273035. If an IPv6 address is given for -bh or -bhc, it is now converted to the

PH
273436. The table in the code that translates DNS record types into text (T_A to
2735 "A" for instance) was missing entries for NS and CNAME. It is just possible
2736 that this could have caused confusion if both these types were looked up
2737 for the same domain, because the text type is used as part of Exim's
2738 per-process caching. But the chance of anyone hitting this buglet seems
2739 very small.

PH
274137. The dnsdb lookup has been extended in a number of ways.

2743 (1) There is a new type, "zns", which walks up the domain tree until it
2744 finds some nameserver records. It should be used with care.

2746 (2) There is a new type, "mxh", which is like "mx" except that it returns

2776 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2777 < 0 before doing a fflush(). This bug looks as though it goes back to the
2778 introduction of TLS in release 3.20, but "sometimes" must have been rare
2779 because the tests only now provoked it.

278447. exim_tidydb, when checking for the continued existence of a message for

2787 deleting retry records that should have stayed in existence.

2794 was generating a temporary error. It now behaves as specified.

PH
280352. Exim crashed if a remote delivery caused a very long error message to be
2804 recorded - for instance if somebody sent an entire SpamAssassin report back
2805 as a large number of 550 error lines. This bug was coincidentally fixed by
2806 increasing the size of one of Exim's internal buffers (big_buffer) that
2807 happened as part of the Exiscan merge. However, to be on the safe side, I
2808 have made the code more robust (and fixed the comments that describe what
2809 is going on).

PH
281153. Now that there can be additional text after "Completed" in log lines (if
2812 the queue_time_overall log selector is set), a one-byte patch to exigrep

2814 the line.

PH
281654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2817 patch that reportedly fixes this has been added. I am not expert enough to
2818 create a test for it. This is what the patch creator wrote:
2819
2820 "I found a little strange behaviour of ldap code when working with
2821 Windows 2003 AD Domain, where users was placed in more than one
2822 Organization Units. When I tried to give exim partial DN, the exit code
2823 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2824 But simultaneously result of request was absolutely normal ldap result,
2825 so I produce this patch..."
2826
3295e65b
PH
2827 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2828 REFERENCE, so I have modified the code to exclude the patch when that macro
2829 is not defined.

PH
283155. Some experimental protocols are using DNS PTR records for new purposes. The
2832 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2833 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2834 leaves it alone. Component reversal etc. now happens only for IP addresses.

284559. Two changes related to the smtp_active_hostname option:
2846
2847 (1) $smtp_active_hostname is now available as a variable.
2848 (2) The default for smtp_banner uses $smtp_active_hostname instead
2849 of $primary_hostname.
2850
b975ba52
PH
285160. The host_aton() function is supposed to be passed a string that is known
2852 to be a valid IP address. However, in the case of IPv6 addresses, it was
2853 not checking this. This is a hostage to fortune. Exim now panics and dies
2854 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2855 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2856 components; fortuitously, this particular loophole had already been fixed
2857 by change 4.50/55 above.
2858
2859 If there are any other similar loopholes, the new check in host_aton()
2860 itself should stop them being exploited. The report I received stated that
2861 data on the command line could provoke the exploit when Exim was running as
2862 exim, but did not say which command line option was involved. All I could
2863 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2864 running as the user.

PH
287563. The daemon start-up calls getloadavg() while still root for those OS that
2876 need the first call to be done as root, but it missed one case: when
2877 deliver_queue_load_max is set with deliver_drop_privilege. This is
2878 necessary for the benefit of the queue runner, because there is no re-exec
2879 when deliver_drop_privilege is set.

2883
60dc5e56
PH
288465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2885 was in use, was not putting the data itself into the right store pool;
2886 consequently, it could be overwritten for a subsequent message in the same
2887 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2888 the caching.)

PH
289267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2893 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2894 the function were treating the return as a boolean value, which happened to
2895 work because 0=false and not-0=true, but is not correct code.
2896

290069. Fixed some compiler warnings in acl.c for the bitmaps specified with

2902 apparently mutter when there is no cast.

PH
290470. If an address verification called from an ACL failed, and did not produce a
2905 user-specific message (i.e. there was only a "system" message), nothing was
2906 put in $acl_verify_message. In this situation, it now puts the system
2907 message there.
2908
00f00ca5
PH
290971. Change 4.23/11 added synchronization checking at the start of an SMTP
2910 session; change 4.31/43 added the unwanted input to the log line - except
2911 that it did not do this in the start of session case. It now does.
2912
c9bdd01c
PH
291372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2914 This is wrong and can cause the other end to generate a synchronization
2915 error if it is another Exim or anything else that does the synchronization
2916 check. A QUIT command is no longer sent after a timeout.

2924 verify = header_sender/callout=defer_ok
2925
76a2d7ba
PH
292675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2927 those file descriptors could be used for SMTP connections. If anything
2928 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2929 could be sent to the SMTP client, causing chaos. The daemon now opens
2930 stdin, stdout, and stderr to /dev/null when it puts itself into the
2931 background.
2932
293376. Arrange for output from Perl's "warn" command to be written to Exim's main
2934 log by default. The user can override this with suitable Perl magic.
2935
04f7d5b9
PH
293677. The use of log_message on a "discard" ACL verb, which is supposed to add to
2937 the log message when discard triggers, was not working for the DATA ACL or
2938 for the non-SMTP ACL.

PH
294078. Error message wording change in sieve.c.
2941
bb6e88ff
PH
294279. If smtp_accept_max_per_host was set, the number of connections could be
2943 restricted to fewer than expected, because the daemon was trying to set up
2944 a new connection before checking whether the processes handling previous
2945 connections had finished. The check for completed processes is now done
2946 earlier. On busy systems, this bug wouldn't be noticed because something
2947 else would have woken the daemon, and it would have reaped the completed
2948 process earlier.
2949
1e70f85b
PH
295080. If a message was submitted locally by a user whose login name contained one
2951 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2952 It caused a spool format error. I have fixed the spool reading code. A
2953 related problem was that the "from" clause in the Received: line became
2954 illegal because of the space(s). It is now covered by ${quote_local_part.

2970----------------------------------------------------
2971See the note above about the 4.44 and 4.50 releases.
2972----------------------------------------------------
2973
2974
2975Exim version 4.44
2976-----------------
2977
2978 1. Change 4.43/35 introduced a bug that caused file counts to be
2979 incorrectly computed when quota_filecount was set in an appendfile
2980 transport
2981
2982 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2983 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2984 place.
2985
2986 3. Give more explanation in the error message when the command for a transport
2987 filter fails to execute.
2988
2989 4. There are several places where Exim runs a non-Exim command in a
2990 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2991 was being done only for the command run by the queryprogram router. It is
2992 now done for all such subprocesses. The other cases are: ${run, transport
2993 filters, and the commands run by the lmtp and pipe transports.
2994
2995 5. Some older OS have a limit of 256 on the maximum number of file
2996 descriptors. Exim was using setrlimit() to set 1000 as a large value
2997 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2998 systems. I've change it so that if it can't get 1000, it tries for 256.
2999
3000 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3001 was an oversight, and furthermore, ever since the addition of extra
3002 controls (e.g. 4.43/32), the checks on when to allow different forms of
3003 "control" were broken. There should now be diagnostics for all cases when a
3004 control that does not make sense is encountered.
3005
3006 7. $recipients is now available in the predata ACL (oversight).
3007
3008 8. Tidy the search cache before the fork to do a delivery from a message
3009 received from the command line. Otherwise the child will trigger a lookup
3010 failure and thereby defer the delivery if it tries to use (for example) a
3011 cached ldap connection that the parent has called unbind on.
3012
3013 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3014 of $address_data from the recipient verification was clobbered by the
3015 sender verification.
3016
301710. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3018 was its contents. (It was OK if the option was not defined at all.)
3019
302011. A "Completed" log line is now written for messages that are removed from
3021 the spool by the -Mrm option.
3022
302312. $host_address is now set to the target address during the checking of
3024 ignore_target_hosts.
3025
302613. When checking ignore_target_hosts for an ipliteral router, no host name was
3027 being passed; this would have caused $sender_host_name to have been used if
3028 matching the list had actually called for a host name (not very likely,
3029 since this list is usually IP addresses). A host name is now passed as
3030 "[x.x.x.x]".
3031
303214. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3033 code that specifies a non-restarting handler (typically sigaction() in
3034 modern systems) in an attempt to fix a rare and obscure crash bug.
3035
303615. Narrowed the window for a race in the daemon that could cause it to ignore
3037 SIGCHLD signals. This is not a major problem, because they are used only to
3038 wake it up if nothing else does.
3039
304016. A malformed maildirsize file could cause Exim to calculate negative values
3041 for the mailbox size or file count. Odd effects could occur as a result.
3042 The maildirsize information is now recalculated if the size or filecount
3043 end up negative.
3044
304517. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3046 support for a long time. Removed HAVE_SYS_VFS_H.
3047
ea3a6f44 304818. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3049
305019. Allow an empty sender to be matched against a lookup in an address list.
3051 Previously the only cases considered were a regular expression, or an
3052 empty pattern.
3053
305420. Exim went into a mad DNS lookup loop when doing a callout where the
3055 host was specified on the transport, if the DNS lookup yielded more than
3056 one IP address.
3057
ea3a6f44
NM
305821. The RFC2047 encoding function was originally intended for short strings
3059 such as real names; it was not keeping to the 75-character limit for
3060 encoded words that the RFC imposes. It now respects the limit, and
3061 generates multiple encoded words if necessary. To be on the safe side, I
3062 have increased the buffer size for the ${rfc2047: expansion operator from
3063 1024 to 2048 bytes.
bbe902f0 3064
ea3a6f44
NM
306522. Failure to deliver a bounce message always caused it to be frozen, even if
3066 there was an errors_to setting on the router. The errors_to setting is now
3067 respected.
bbe902f0
PH
3068
306923. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3070 canonical form (fully expanded) before being placed in
3071 $sender_host_address.
3072
307324. Updated eximstats to version 1.33
3074
ea3a6f44
NM
307525. Include certificate and key file names in error message when GnuTLS fails
3076 to set them up, because the GnuTLS error message doesn't include the name
3077 of the failing file when there is a problem reading it.
bbe902f0
PH
3078
307926. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3080 As per change 25.
bbe902f0 3081
ea3a6f44

308227. Reset the locale to "C" after calling embedded Perl, in case it was changed
3083 (this can affect the format of dates).
bbe902f0 3084
ea3a6f44
NM
308528. exim_tidydb, when checking for the continued existence of a message for
3086 which it has found a message-specific retry record, was not finding
3087 messages that were in split spool directories. Consequently, it was
3088 deleting retry records that should have stayed in existence.

3089
309029. eximstats updated to version 1.35

3155 < 0 before doing a fflush(). This bug looks as though it goes back to the

3160Exim version 4.43
3161-----------------
3162
3163 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3164 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3165 Now it returns an integer. A number of calls were still expecting a T/F
3166 return. Fortuitously, in all cases, the tests worked in OK situations,
3167 which is the norm. However, things would have gone wrong on any write
3168 failures on the smtp file descriptor. This function is used when sending
3169 messages over SMTP and also when doing verify callouts.
3170
3171 2. When Exim is called to do synchronous delivery of a locally submitted
3172 message (the -odf or -odi options), it no longer closes stderr before doing
3173 the delivery.
3174
3175 3. Implemented the mua_wrapper option.
3176
3177 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3178
3179 5. Implemented the functions header_remove(), header_testname(),
3180 header_add_at_position(), and receive_remove_recipient(), and exported them
3181 to local_scan().
3182
3183 6. If an ACL "warn" statement specified the addition of headers, Exim already
3184 inserted X-ACL-Warn: at the start if there was no header name. However, it
3185 was not making this test for the second and subsequent header lines if
3186 there were newlines in the string. This meant that an invalid header could
3187 be inserted if Exim was badly configured.
3188
3189 7. Allow an ACL "warn" statement to add header lines at the start or after all
3190 the Received: headers, as well as at the end.
3191
3192 8. Added the rcpt_4xx retry error code.
3193
3194 9. Added postmaster_mailfrom=xxx to callout verification option.
3195
319610. Added mailfrom=xxxx to the callout verification option, for verify=
3197 header_sender only.
3198
319911. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3200 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3201
320212. Inserted some casts to stop certain compilers warning when using pointer
3203 differences as field lengths or precisions in printf-type calls (mostly
3204 affecting debugging statements).
3205
320613. Added optional readline() support for -be (dynamically loaded).
3207
320814. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3209 same clock tick as a message's arrival, so that its received time was the
3210 same as the "first fail" time on the retry record, and that message
3211 remained on the queue past the ultimate address timeout, every queue runner
3212 would try a delivery (because it was past the ultimate address timeout) but
3213 after another failure, the ultimate address timeout, which should have then
3214 bounced the address, did not kick in. This was a "< instead of <=" error;
3215 in most cases the first failure would have been in the next clock tick
3216 after the received time, and all would be well.
3217
321815. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3219 being recognized when the domain list was tested by the match_domain
3220 condition in an expansion string.
3221
322216. Added the ${str2b64: operator.
3223
322417. Exim was always calling setrlimit() to set a large limit for the number of
3225 processes, without checking whether the existing limit was already
3226 adequate. (It did check for the limit on file descriptors.) Furthermore,
3227 errors from getrlimit() and setrlimit() were being ignored. Now they are
3228 logged to the main and panic logs, but Exim does carry on, to try to do its
3229 job under whatever limits there are.
3230
323118. Imported PCRE 5.0.
3232
323319. Trivial typo in log message " temporarily refused connection" (the leading
3234 space).
3235
323620. If the log selector return_path_on_delivery was set and an address was
3237 redirected to /dev/null, the delivery process crashed because it assumed
3238 that a return path would always be set for a "successful" delivery. In this
3239 case, the whole delivery is bypassed as an optimization, and therefore no
3240 return path is set.
3241
324221. Internal re-arrangement: the function for sending a challenge and reading
3243 a response while authentication was assuming a zero-terminated challenge
3244 string. It's now changed to take a pointer and a length, to allow for
3245 binary data in such strings.
3246
324722. Added the cyrus_sasl authenticator (code supplied by MBM).
3248
324923. Exim was not respecting finduser_retries when seeking the login of the
3250 uid under which it was called; it was always trying 10 times. (The default
3251 setting of finduser_retries is zero.) Also, it was sleeping after the final
3252 failure, which is pointless.
3253
325424. Implemented tls_on_connect_ports.
3255
325625. Implemented acl_smtp_predata.
3257
325826. If the domain in control=submission is set empty, Exim assumes that the
3259 authenticated id is a complete email address when it generates From: or
3260 Sender: header lines.
3261
326227. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3263 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3264 chown and chgrp in /bin and hostname in /usr/bin.
3265
326628. Exim was keeping the "process log" file open after each use, just as it
3267 does for the main log. This opens the possibility of it remaining open for
3268 long periods when the USR1 signal hits a daemon. Occasional processlog
3269 errors were reported, that could have been caused by this. Anyway, it seems
3270 much more sensible not to leave this file open at all, so that is what now
3271 happens.
3272
327329. The long-running daemon process does not normally write to the log once it
3274 has entered its main loop, and it closes the log before doing so. This is
3275 so that log files can straightforwardly be renamed and moved. However,
3276 there are a couple of unusual error situations where the daemon does write
3277 log entries, and I had neglected to close the log afterwards.
3278
327930. The text of an SMTP error response that was received during a remote
3280 delivery was being truncated at 512 bytes. This is too short for some of
3281 the long messages that one sometimes sees. I've increased the limit to
3282 1024.
3283
328431. It is now possible to make retry rules that apply only when a message has a
3285 specific sender, in particular, an empty sender.
3286
328732. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3288 it possible to be selective about when SMTP synchronization is enforced.
3289
329033. Added "control = caseful_local_part" and "control = "caselower_local_part".
3291
329232. Implemented hosts_connection_nolog.
3293
329433. Added an ACL for QUIT.
3295
329634. Setting "delay_warning=" to disable warnings was not working; it gave a
3297 syntax error.
3298
329935. Added mailbox_size and mailbox_filecount to appendfile.
3300
330136. Added control = no_multiline_responses to ACLs.
3302
330337. There was a bug in the logic of the code that waits for the clock to tick
3304 in the case where the clock went backwards by a substantial amount such
3305 that the microsecond fraction of "now" was more than the microsecond
3306 fraction of "then" (but the whole seconds number was less).
3307
330838. Added support for the libradius Radius client library this is found on
3309 FreeBSD (previously only the radiusclient library was supported).
3310
3311
3312Exim version 4.42
3313-----------------
3314
3315 1. When certain lookups returned multiple values in the form name=value, the
3316 quoting of the values was not always being done properly. Specifically:
3317 (a) If the value started with a double quote, but contained no whitespace,
3318 it was not quoted.
3319 (b) If the value contained whitespace other than a space character (i.e.
3320 tabs or newlines or carriage returns) it was not quoted.
3321 This fix has been applied to the mysql and pgsql lookups by writing a
3322 separate quoting function and calling it from the lookup code. The fix
3323 should probably also be applied to nisplus, ibase and oracle lookups, but
3324 since I cannot test any of those, I have not disturbed their existing code.
3325
3326 2. A hit in the callout cache for a specific address caused a log line with no
3327 reason for rejecting RCPT. Now it says "Previous (cached) callout
3328 verification failure".
3329
3330 3. There was an off-by-one bug in the queryprogram router. An over-long
3331 return line was truncated at 256 instead of 255 characters, thereby
3332 overflowing its buffer with the terminating zero. As well as fixing this, I
3333 have increased the buffer size to 1024 (and made a note to document this).
3334
3335 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3336 when Exim is waiting for an SMTP response from a remote server, Exim
3337 restarts its select() call on the socket, thereby resetting its timeout.
3338 This is not a problem when such interrupts are rare. Somebody set up a cron
3339 job to run exiwhat every 2 minutes, which is less than the normal select()
3340 timeout (5 or 10 minutes). This meant that the select() timeout never
3341 kicked in because it was always reset. I have fixed this by comparing the
3342 time when an interrupt arrives with the time at the start of the first call
3343 to select(). If more time than the timeout has elapsed, the interrupt is
3344 treated as a timeout.
3345
3346 5. Some internal re-factoring in preparation for the addition of Sieve
3347 extensions (by MH). In particular, the "personal" test is moved to a
3348 separate function, and given an option for scanning Cc: and Bcc: (which is
3349 not set for Exim filters).
3350
3351 6. When Exim created an email address using the login of the caller as the
3352 local part (e.g. when creating a From: or Sender: header line), it was not
3353 quoting the local part when it contained special characters such as @.
3354
3355 7. Installed new OpenBSD configuration files.
3356
3357 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3358 try to make them clearer.
3359
3360 9. Callout options, other than the timeout value, were being ignored when
3361 verifying sender addresses in header lines. For example, when using
3362
3363 verify = header_sender/callout=no_cache
3364
3365 the cache was (incorrectly) being used.
3366
336710. Added a missing instance of ${EXE} to the exim_install script; this affects
3368 only the Cygwin environment.
3369
337011. When return_path_on_delivery was set as a log selector, if different remote
3371 addresses in the same message used different return paths and parallel
3372 remote delivery occurred, the wrong values would sometimes be logged.
3373 (Whenever a remote delivery process finished, the return path value from
3374 the most recently started remote delivery process was logged.)
3375
337612. RFC 3848 specifies standard names for the "with" phrase in Received: header
3377 lines when AUTH and/or TLS are in use. This is the "received protocol"
3378 field. Exim used to use "asmtp" for authenticated SMTP, without any
3379 indication (in the protocol name) for TLS use. Now it follows the RFC and
3380 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3381 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3382 names appear in log lines as well as in Received: header lines.
3383
338413. Installed MH's patches for Sieve to add the "copy" and "vacation"
3385 extensions, and comparison tests, and to fix some bugs.
3386
338714. Changes to the "personal" filter test:
3388
3389 (1) The test was buggy in that it was just doing the equivalent of
3390 "contains" tests on header lines. For example, if a user's address was
3391 anne@some.where, the "personal" test would incorrectly be true for
3392
3393 To: susanne@some.where
3394
3395 This test is now done by extracting each address from the header in turn,
3396 and checking the entire address. Other tests that are part of "personal"
3397 are now done using regular expressions (for example, to check local parts
3398 of addresses in From: header lines).
3399
3400 (2) The list of non-personal local parts in From: addresses has been
3401 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3402 taken from the Sieve specification recommendations.
3403
3404 (3) If the message contains any header line starting with "List-" it is
3405 treated as non-personal.
3406
3407 (4) The test for "circular" in the Subject: header line has been removed
3408 because it now seems ill-conceived.
3409
341015. Minor typos in src/EDITME comments corrected.
3411
341216. Installed latest exipick from John Jetmore.
3413
341417. If headers_add on a router specified a text string that was too long for
3415 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3416 of string_sprintf() is now avoided.
3417
341818. $message_body_size was not set (it was always zero) when running the DATA
3419 ACL and the local_scan() function.
3420
342119. For the "mail" command in an Exim filter, no default was being set for
3422 the once_repeat time, causing a random time value to be used if "once" was
3423 specified. (If the value happened to be <= 0, no repeat happened.) The
3424 default is now 0s, meaning "never repeat". The "vacation" command was OK
3425 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3426 (I found it when inspecting the code).
3427
342820. There is now an overall timeout for performing a callout verification. It
3429 defaults to 4 times the callout timeout, which applies to individual SMTP
3430 commands during the callout. The overall timeout applies when there is more
3431 than one host that can be tried. The timeout is checked before trying the
3432 next host. This prevents very long delays if there are a large number of
3433 hosts and all are timing out (e.g. when the network connections are timing
3434 out). The value of the overall timeout can be changed by specifying an
3435 additional sub-option for "callout", called "maxwait". For example:
3436
3437 verify = sender/callout=5s,maxwait=20s
3438
343921. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3440 to the end before writing, but this should make it even safer).
3441
344222. Exim was forgetting that it had advertised PIPELINING for the second and
3443 subsequent messages on an SMTP connection. It was also
