71PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
72 If dropping privileges for untrusted macros, we disabled normal logging

74 the case, and it resulted in successful deliveries going unlogged.
75 Fixed. Reported by Andreas Metzler.

407TK/01 Add preliminary DKIM support. Currently requires a forked version of
408 ALT-N's libdkim that I have put here:
409 http://duncanthrax.net/exim-experimental/
410
411 Note to Michael Haardt: I had to rename some vars in sieve.c. They
412 were called 'true' and it seems that C99 defines that as a reserved
413 keyword to be used with 'bool' variable types. That means you could
414 not include C99-style headers which use bools without triggering
415 build errors in sieve.c.

432
433PH/01 Another patch from the Sieve maintainer.
434
6a3bceb1
PH
435PH/02 When an IPv6 address is converted to a string for single-key lookup
436 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
437 dots are used instead of colons so that keys in lsearch files need not
438 contain colons. This was done some time before quoting was made available
439 in lsearch files. However, iplsearch files do require colons in IPv6 keys
440 (notated using the quote facility) so as to distinguish them from IPv4
441 keys. This meant that lookups for IP addresses in host lists did not work
442 for iplsearch lookups.
443
444 This has been fixed by arranging for IPv6 addresses to be expressed with
445 colons if the lookup type is iplsearch. This is not incompatible, because
446 previously such lookups could never work.
447
448 The situation is now rather anomolous, since one *can* have colons in
449 ordinary lsearch keys. However, making the change in all cases is
450 incompatible and would probably break a number of configurations.
451
2e30fa9d
TK
452TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
453 version.
454
0806a9c5
MH
455MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
456 conversion specification without a maximum field width, thereby enabling
457 a rogue spamd server to cause a buffer overflow. While nobody in their
458 right mind would setup Exim to query an untrusted spamd server, an
459 attacker that gains access to a server running spamd could potentially
460 exploit this vulnerability to run arbitrary code as the Exim user.

TK
462TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
463 $primary_hostname instead of what libspf2 thinks the hosts name is.
464
0f2cbd1b
MH
465MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
466 a directory entry by the name of the lookup key. Previously, if a
467 symlink pointed to a non-existing file or a file in a directory that
468 Exim lacked permissions to read, a lookup for a key matching that
469 symlink would fail. Now it is enough that a matching directory entry
470 exists, symlink or not. (Bugzilla 503.)
471
2b85bce7
PH
472PH/03 The body_linecount and body_zerocount variables are now exported in the
473 local_scan API.

476
6c512171
PH
477PH/05 Unset $tls_cipher and $tls_peerdn before making a connection as a client.
478 This means they are set thereafter only if the connection becomes
479 encrypted.
480
481PH/06 Added the client_condition to authenticators so that some can be skipped
482 by clients under certain conditions.
483
aa6dc513
PH
484PH/07 The error message for a badly-placed control=no_multiline_responses left
485 "_responses" off the end of the name.

8f240103
PH
489PH/09 Tidied the code for creating ratelimiting keys, creating them explicitly
490 (without spaces) instead of just copying the configuration text.

499 way in which PCRE > 7.0 is built.

509
8932dffe
PH
510PH/18 If a system quota error occurred while trying to create the file for
511 a maildir delivery, the message "Mailbox is full" was not appended to the
512 bounce if the delivery eventually timed out. Change 4.67/27 below applied
513 only to a quota excession during the actual writing of the file.
d6a60c0f 514
ddea74fa 515PH/19 It seems that peer DN values may contain newlines (and other non-printing
48ed62d9
PH
516 characters?) which causes problems in log lines. The DN values are now
517 passed through string_printing() before being added to log lines.
518
ddea74fa 519PH/20 Added the "servers=" facility to MySQL and PostgreSQL lookups. (Oracle
b7670459
PH
520 and InterBase are left for another time.)

MH
536MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
537 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
538 Jan Srzednicki.
539
b4ed4da0
PH
540PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
541 issue a MAIL command.
542
431b7361
PH
543PH/02 In an ACL statement such as
544
545 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
546
547 if a client was not listed at all, or was listed with a value other than
548 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
549 the condition was not true (as it should be), so access was not denied.
550 The bug was that the ! inversion was incorrectly passed on to the second
551 item. This has been fixed.
552
553PH/03 Added additional dnslists conditions == and =& which are different from
554 = and & when the dns lookup returns more than one IP address.
555
83da1223
PH
556PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
557 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
558
54fc8428
PH
559PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
560 FSYNC, which compiles an option called disable_fsync that allows for
561 bypassing fsync(). The documentation is heavily laced with warnings.
562
34c5e8dd
SC
563SC/01 Updated eximstats to collate all SpamAssassin rejects into one bucket.

bbe15da8
PH
565PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
566 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
567 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
568 including adding "make clean"; (3) Added -fPIC when compiling the test
569 dynamically loaded module, to get rid of a warning.
570
0e8a9471
MH
571MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
572 message fails, move_frozen_messages = true and ignore_bounce_errors_after
573 = 0s. The bug is otherwise harmless.
574
f0872424
PH
575PH/07 There was a bug in the dovecot authenticator such that the value of
576 $auth1 could be overwritten, and so not correctly preserved, after a
577 successful authentication. This usually meant that the value preserved by
578 the server_setid option was incorrect.
579
b01dd148
PH
580PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.

6bf342e1
PH
582PH/09 Installed PCRE release 7.0.
583
273f34d0
PH
584PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
585 run for batched SMTP input. It is now run at the start of every message
586 in the batch. While fixing this I discovered that the process information
587 (output by running exiwhat) was not always getting set for -bs and -bS
588 input. This is fixed, and it now also says "batched" for BSMTP.
589
cf8b11a5
PH
590PH/11 Added control=no_pipelining.
591
41c7c167
PH
592PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
593 patch, slightly modified), and move the expansion of helo_data till after
594 the connection is made in the smtp transport (so it can use these
595 values).

608 no_callout_flush is set.
609
09945f1e
PH
610PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
611 was true (the default) a successful delivery failed to delete the retry
612 item, thus causing premature timeout of the address. The bug is now
613 fixed.
614
c51b8e75
PH
615PH/20 Added hosts_avoid_pipelining to the smtp transport.
616
e28326d8
PH
617PH/21 Long custom messages for fakedefer and fakereject are now split up
618 into multiline reponses in the same way that messages for "deny" and
619 other ACL rejections are.

75b1493f
PH
621PH/22 Applied Jori Hamalainen's speed-up changes and typo fixes to exigrep,
622 with slight modification.

625 draft, changing the syntax and factoring some duplicate code".
626
4311097e
PH
627PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
628 for deliveries of the second and subsequent messages over the same SMTP
629 connection.
630
29f89cad
PH
631PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
632 ${reduce, with only minor "tidies".
633
5e687460
SC
634SC/02 Applied Daniel Tiefnig's patch to improve the '($parent) =' pattern match.
635
c3611384
PH
636PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
637 expansion side effects.
638
5a11a7b4
PH
639PH/27 When a message times out after an over-quota error from an Exim-imposed
640 quota, the bounce message says "mailbox is full". This message was not
641 being given when it was a system quota that was exceeded. It now should
642 be the same.
643
0e20aff9
MH
644MH/03 Made $recipients available in local_scan(). local_scan() already has
645 better access to the recipient list through recipients_list[], but
646 $recipients can be useful in postmaster-provided expansion strings.
647
ca86f471
PH
648PH/28 The $smtp_command and $smtp_command_argument variables were not correct
649 in the case of a MAIL command with additional options following the
650 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
651 were accidentally chopped off.
652
a14e5636
PH
653PH/29 SMTP synchronization checks are implemented when a command is read -
654 there is a check that no more input is waiting when there shouldn't be
655 any. However, for some commands, a delay in an ACL can mean that it is
656 some time before the response is written. In this time, more input might
657 arrive, invalidly. So now there are extra checks after an ACL has run for
658 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
659 pipelining has not been advertised.
660
ec95d1a6
PH
661PH/30 MH's patch to allow iscntrl() characters to be list separators.
662
42855d71
PH
663PH/31 Unlike :fail:, a custom message specified with :defer: was not being
664 returned in the SMTP response when smtp_return_error_details was false.
665 This has been fixed.
666
57c2c631
PH
667PH/32 Change the Dovecot authenticator to use read() and write() on the socket
668 instead of the C I/O that was originally supplied, because problems were
669 reported on Solaris.
670
58c01c94
PH
671PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
672 Exim which did not show up earlier: it was assuming that a call to
673 SSL_CTX_set_info_callback() might give an error value. In fact, there is
674 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
675 was a macro that became an assignment, so it seemed to work. This has
676 changed to a proper function call with a void return, hence the compile
677 error. Exim's code has been fixed.
678
dee5a20a
PH
679PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
680 cpus.
681
d2ee6114
PH
682PH/35 Applied a patch from the Sieve maintainer which fixes a bug in "notify".
683
b2d5182b
PH
684PH/36 Applied John Jetmore's patch to add -v functionality to exigrep.
685
79749a79
PH
686PH/37 If a message is not accepted after it has had an id assigned (e.g.
687 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
688 "Completed" line in the log. When some messages of this type were
689 selected by exigrep, they were listed as "not completed". Others were
690 picked up by some special patterns. I have improved the selection
691 criteria to be more general.
79749a79 692
c456d9bb
PH
693PH/38 The host_find_failed option in the manualroute router can now be set
694 to "ignore", to completely ignore a host whose IP address cannot be
695 found. If all hosts are ignored, the behaviour is controlled by the new
696 host_all_ignored option.
697
cd9868ec
PH
698PH/39 In a list of hosts for manualroute, if one item (either because of multi-
699 homing or because of multiple MX records with /mx) generated more than
700 one IP address, and the following item turned out to be the local host,
701 all the secondary addresses of the first item were incorrectly removed
702 from the list, along with the local host and any following hosts (which
703 is what is supposed to happen).
704
ebeaf996
PH
705PH/40 When Exim receives a message, it writes the login name, uid, and gid of
706 whoever called Exim into the -H file. In the case of the daemon it was
707 behaving confusingly. When first started, it used values for whoever
708 started the daemon, but after a SIGHUP it used the Exim user (because it
709 calls itself on a restart). I have changed the code so that it now always
710 uses the Exim user.
711
2679d413
PH
712PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
713 message are rejected with the same error (e.g. no authentication or bad
714 sender address), and a DATA command is nevertheless sent (as can happen
715 with PIPELINING or a stupid MUA), the error message that was given to the
716 RCPT commands is included in the rejection of the DATA command. This is
717 intended to be helpful for MUAs that show only the final error to their
718 users.

730PH/43 Yet another patch from the Sieve maintainer.
731
58eb016e 732PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
733 the response to the final '.' that terminates a message, but only in the
734 case where the client has not sent further data following the '.'
735 (unfortunately, this is allowed). However, in many cases there won't be
736 any further data because there won't be any more messages to send. A call
737 to select() can be used: if it shows that the input is "ready", there is
738 either input waiting, or the socket has been closed. An attempt to read
739 the next input character can distinguish the two cases. Previously, Exim
58eb016e 740 would have sent an OK response which the client would never have see.
563b63fa
PH
741 This could lead to message repetition. This fix should cure that, at
742 least in a lot of common cases.

748Exim version 4.66
749-----------------
750
751PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
752 fixed by 4.65/MH/01 (is this a record?) are fixed:
753
754 (i) An empty string was always treated as zero by the numeric comparison
755 operators. This behaviour has been restored.
756
757 (ii) It is documented that the numeric comparison operators always treat
758 their arguments as decimal numbers. This was broken in that numbers
759 starting with 0 were being interpreted as octal.
760
761 While fixing these problems I realized that there was another issue that
762 hadn't been noticed. Values of message_size_limit (both the global option
763 and the transport option) were treated as octal if they started with 0.
764 The documentation was vague. These values are now always treated as
765 decimal, and I will make that clear in the documentation.

MH
775MH/01 Don't check that the operands of numeric comparison operators are
776 integers when their expansion is in "skipping" mode (fixes bug
777 introduced by 4.64-PH/07).
778
4362ff0d
PH
779PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
780 child addresses, Exim now panics and dies. Previously, because the count
781 is held in a short int, deliveries were likely to be lost. As such a
782 large number of recipients for a single message is ridiculous
783 (performance will be very, very poor), I have chosen to impose a limit
784 rather than extend the field.

790TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
791 leftover -K file (the existence of which was triggered by #402).
792 While we were at it, introduced process PID as part of the -K
793 filename. This should rule out race conditions when creating
794 these files.
795
796TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
797 processing considerably. Previous code took too long for large mails,
798 triggering a timeout which in turn triggers #401.
799

804TF/01 In the add_headers option to the mail command in an Exim filter,

807 in the field name.

PH
809PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
810 callout verification, Exim cached a "reject" for the entire domain. This
811 is correct for most verifications, but it is not correct for a recipient
812 verification with use_sender or use_postmaster set, because in that case
813 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
814 case of MAIL FROM:<> rejection from other early rejections (e.g.
815 rejection of HELO). When verifying a recipient using a non-null MAIL
816 address, the cache is ignored if it shows MAIL FROM:<> rejection.
817 Whatever the result of the callout, the value of the domain cache is
818 left unchanged (for any other kind of callout, getting as far as trying
819 RCPT means that the domain itself is ok).

853PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
854 hostname. This is wrong, because it relates to the incoming message (and
855 probably the interface on which it is arriving) and not to the outgoing
856 callout (which could be using a different interface). This has been
857 changed to use the value of the helo_data option from the smtp transport
858 instead - this is what is used when a message is actually being sent. If
859 there is no remote transport (possible with a router that sets up host
860 addresses), $smtp_active_hostname is used.

14aa5a05 862PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 863 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
864 (a) The code assumed that strncpy() returns a negative number on buffer
865 overflow, which isn't the case. Replaced with Exim's string_format()
866 function.
867 (b) There were several signed/unsigned issues. I just did the minimum
868 hacking in of casts. There is scope for a larger refactoring.
869 (c) The code used strcasecmp() which is not a standard C function.
870 Replaced with Exim's strcmpic() function.
871 (d) The code set only $1; it now sets $auth1 as well.
872 (e) A simple test gave the error "authentication client didn't specify
873 service in request". It would seem that Dovecot has changed its
874 interface. Fortunately there's a specification; I followed it and
875 changed what the client sends and it appears to be working now.

880PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
881 address A is aliased to B and C, where B exists and C does not. Without
882 -v the output is "A verified" because verification stops after a
883 successful redirection if more than one address is generated. However,
884 with -v the child addresses are also verified. Exim was outputting "A
885 failed to verify" and then showing the successful verification for C,
886 with its parentage. It now outputs "B failed to verify", showing B's
887 parentage before showing the successful verification of C.

892
322050c2
PH
893PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
894 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
895 they consult the DNS. I had assumed they would set it the way they
896 wanted; and indeed my experiments on Linux seem to show that in some
897 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
898 To be on the safe side, however, I have now made the interface to
899 host_find_byname() similar to host_find_bydns(), with an argument
900 containing the DNS resolver options. The host_find_byname() function now
901 sets these options at its start, just as host_find_bydns() does. The smtp
902 transport options dns_qualify_single and dns_search_parents are passed to
903 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
904 of host_find_byname() use the default settings of RES_DEFNAMES
905 (qualify_single) but not RES_DNSRCH (search_parents).

907PH/17 Applied (a modified version of) Nico Erfurth's patch to make
908 spool_read_header() do less string testing, by means of a preliminary
909 switch on the second character of optional "-foo" lines. (This is
910 overdue, caused by the large number of possibilities that now exist.
911 Originally there were few.) While I was there, I also converted the
912 str(n)cmp tests so they don't re-test the leading "-" and the first
913 character, in the hope this might squeeze out yet more improvement.

PH
915PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
916 flag allowing group syntax was set by the header_syntax check but not
917 turned off, possible causing trouble later; (2) The flag was not being
918 set at all for the header_verify test, causing "group"-style headers to
919 be rejected. I have now set it in this case, and also caused header_
920 verify to ignore an empty address taken from a group. While doing this, I
921 came across some other cases where the code for allowing group syntax
922 while scanning a header line wasn't quite right (mostly, not resetting
923 the flag correctly in the right place). These bugs could have caused
924 trouble for malformed header lines. I hope it is now all correct.
925
602e59e5
PH
926PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
927 with the "reply" argument non-NULL. The code, however (which originally
928 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
929 but it didn't always do it. This confused somebody who was copying the
930 code for some other use. I have removed all the tests.

PH
932PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
933 feature that was used to support insecure browsers during the U.S. crypto
934 embargo. It requires special client support, and Exim is probably the
935 only MTA that supported it -- and would never use it because real RSA is
936 always available. This code has been removed, because it had the bad
937 effect of slowing Exim down by computing (never used) parameters for the
938 RSA_EXPORT functionality.

940PH/21 On the advice of Timo Sirainen, added a check to the dovecot
941 authenticator to fail if there's a tab character in the incoming data
942 (there should never be unless someone is messing about, as it's supposed
943 to be base64-encoded). Also added, on Timo's advice, the "secured" option
944 if the connection is using TLS or if the remote IP is the same as the
945 local IP, and the "valid-client-cert option" if a client certificate has
946 been verified.

PH
977
978PH/30 Exim was sometimes attempting to deliver messages that had suffered
979 address errors (4xx response to RCPT) over the same connection as other
980 messages routed to the same hosts. Such deliveries are always "forced",
981 so retry times are not inspected. This resulted in far too many retries
982 for the affected addresses. The effect occurred only when there were more
983 hosts than the hosts_max_try setting in the smtp transport when it had
984 the 4xx errors. Those hosts that it had tried were not added to the list
985 of hosts for which the message was waiting, so if all were tried, there
986 was no problem. Two fixes have been applied:
987
988 (i) If there are any address or message errors in an SMTP delivery, none
989 of the hosts (tried or untried) are now added to the list of hosts
990 for which the message is waiting, so the message should not be a
991 candidate for sending over the same connection that was used for a
992 successful delivery of some other message. This seems entirely
993 reasonable: after all the message is NOT "waiting for some host".
994 This is so "obvious" that I'm not sure why it wasn't done
995 previously. Hope I haven't missed anything, but it can't do any
996 harm, as the worst effect is to miss an optimization.
997
998 (ii) If, despite (i), such a delivery is accidentally attempted, the
999 routing retry time is respected, so at least it doesn't keep
1000 hammering the server.

1015PH/35 The error "getsockname() failed: connection reset by peer" was being
1016 written to the panic log as well as the main log, but it isn't really

1018 removed the panic log writing for the ECONNRESET error when getsockname()
1019 fails.
1020
48c7f9e2
PH
1021PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1022 runs only) independently of the message's sender address. This meant
1023 that, if the 4xx error was in fact related to the sender, a different
1024 message to the same recipient with a different sender could confuse
1025 things. In particualar, this can happen when sending to a greylisting
1026 server, but other circumstances could also provoke similar problems.
1027 I have changed the default so that the retry time for these errors is now
1028 based a combination of the sender and recipient addresses. This change
1029 can be overridden by setting address_retry_include_sender=false in the
1030 smtp transport.

1298PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1300 Unfortunately, if there is a major crisis, such as a disk failure,
1301 tcp-wrappers gives "deny", whereas what one would like would be some
1302 kind of temporary error. A kludge has been added to help with this.
1303 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1304 554 error is used if errno is still zero or contains ENOENT (which occurs
1305 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1306 451 error is used.

1342PH/01 The code for finding all the local interface addresses on a FreeBSD
1343 system running IPv6 was broken. This may well have applied to all BSD
1344 systems, as well as to others that have similar system calls. The broken
1345 code found IPv4 interfaces correctly, but gave incorrect values for the
1346 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1347 that it would not match correctly against @[] and not recognize the IPv6
1348 addresses as local.

1391 autoreply, Exim could try to deliver to a non-existent relative file

1414 (a) Failures to set uid/gid, the current directory, or a process leader
1415 in a subprocess such as that created by queryprogram now generate
1416 suitable debugging ouput when -d is set.

1426 additional section of a DNS packet that returns MX or SRV records.
1427 Instead, it always explicitly searches for A/AAAA records. This avoids
1428 major problems that occur when a DNS server includes only records of one
1429 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1430 fixed another bug: if SRV records were looked up and the corresponding
1431 address records were *not* found in the additional section, the port
1432 values from the SRV records were lost.

1434PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1442PH/19 When calculating a retry time, Exim used to measure the "time since
1443 failure" by looking at the "first failed" field in the retry record. Now
1444 it does not use this if it is later than than the arrival time of the
1445 message. Instead it uses the arrival time. This makes for better
1446 behaviour in cases where some deliveries succeed, thus re-setting the
1447 "first failed" field. An example is a quota failure for a huge message
1448 when small messages continue to be delivered. Without this change, the
1449 "time since failure" will always be short, possible causing more frequent
1450 delivery attempts for the huge message than are intended.

1547PH/42 The content-scanning code uses fopen() to create files in which to put

1550 files with open(), and sets the required mode explicitly. Thus, these
1551 files were ending up world-writeable. This was not a big issue, because,
1552 being within the spool directory, they were not world-accessible. I have
1553 created a function called modefopen, which takes an additional mode
1554 argument. It sets umask(777), creates the file, chmods it to the required
1555 mode, then resets the umask. All the relevant calls to fopen() in the

1582PH/50 When an Exim quota was set without a file count quota, and mailbox_size
1583 was also set, the appendfile transport was unnecessarily scanning a
1584 directory of message files (e.g. for maildir delivery) to find the count
1585 of files (along with the size), even though it did not need this
1586 information. It now does the scan only if it needs to find either the
1587 size of the count of files.

1591PH/52 Two bugs concerned with error handling when the smtp transport is
1592 used in LMTP mode:
1593
1594 (i) Exim was not creating retry information for temporary errors given
1595 for individual recipients after the DATA command when the smtp transport
1596 was used in LMTP mode. This meant that they could be retried too
1597 frequently, and not timed out correctly.
1598
1599 (ii) Exim was setting the flag that allows error details to be returned
1600 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1601 recipients that were returned after the DATA command.
1602
1603PH/53 This is related to PH/52, but is more general: for any failing address,
1604 when detailed error information was permitted to be returned to the
1605 sender, but the error was temporary, then after the final timeout, only
1606 "retry timeout exceeded" was returned. Now it returns the full error as
1607 well as "retry timeout exceeded".

1666 been fixed. However, if bounce_return_message is true and bounce_return_
1667 body is false, the headers that are returned for a non-SMTP message

1677PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1678 function verify_get_ident() calls ip_connect() to connect a socket, but
1679 if the "connect()" function timed out, ip_connect() used to close the
1680 socket. However, verify_get_ident() also closes the socket later, and in
1681 between Exim writes to the log, which may get opened at this point. When
1682 the socket was closed in ip_connect(), the log could get the same file
1683 descriptor number as the socket. This naturally causes chaos. The fix is
1684 not to close the socket in ip_connect(); the socket should be closed by
1685 the function that creates it. There was only one place in the code where
1686 this was missing, in the iplookup router, which I don't think anybody now
1687 uses, but I've fixed it anyway.

1710
1711 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1712 string.
1713
1714 (3) Reset the variables that are obtained from the first argument of
1715 ${prvscheck and used in the second argument before leaving the code,
1716 because their memory is reclaimed, so using them afterwards may do
1717 silly things.
1718
1719 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1720 one (it's much easier than Tom thought :-).

1738 may be more than one such address. If so, they are comma-separated, like

1743PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1744 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1745 not being looked up in the rDNS to get a host name, Exim was showing the
1746 IP address twice in Received: lines, even though the IP addresses were
1747 identical. For example:
1748
1749 Received: from [1.2.3.4] (helo=[1.2.3.4])
1750
1751 However, if the real host name was known, it was omitting the HELO data
1752 if it matched the actual IP address. This has been tidied up so that it
1753 doesn't show the same IP address twice.

1779PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

1781
1782 Auto-submitted: auto-generated
1783
1784 in the messages that it generates (bounce messages and others, such as
1785 warnings). In the case of bounce messages for non-SMTP mesages, there was
1786 also a typo: it was using "Auto_submitted" (underscore instead of
1787 hyphen). Since every message generated by Exim is necessarily in response
1788 to another message, thes have all been changed to:
1789
1790 Auto-Submitted: auto-replied
1791
1792 in accordance with these statements in the RFC:
1793
1794 The auto-replied keyword:
1795
1796 - SHOULD be used on messages sent in direct response to another
1797 message by an automatic process,
1798
1799 - MUST NOT be used on manually-generated messages,
1800
1801 - MAY be used on Delivery Status Notifications (DSNs) and Message
1802 Disposition Notifications (MDNs),

1842PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1843 canonical form (as documented). However, after a host name lookup from
1844 the IP address, check_host() was doing a simple string comparison with
1845 addresses acquired from the DNS when checking that the found name did
1846 have the original IP as one of its addresses. Since any found IPv6
1847 addresses are likely to be in abbreviated form, the comparison could
1848 fail. Luckily, there already exists a function for doing the comparison
1849 by converting both addresses to binary, so now that is used instead of
1850 the text comparison.

1852PH/20 There was another similar case to PH/19, when a complete host name was

2148 with the definition in sysexits.h (which is #included earlier).
2149 Fortunately, Exim does not actually use EX_OK. The code used to try to
2150 preserve the sysexits.h value, by assumimg that macro definitions were
2151 scanned for macro replacements. I have been disabused of this notion,

2157 This seems wrong - if the receiver was accepting one byte at a time it
2158 would take for ever. The timeout is now adjusted when this happens. It
2159 doesn't have to be particularly precise.

2235 case the guess is not the same as the compiled default, so the script
2236 suddenly stopped working when I started to use syslog. The patch checks

2369 that changes the way the GnuTLS parameters are stored in the cache file.
2370 The new format can be generated externally. For backward compatibility,
2371 if the data in the cache doesn't make sense, Exim assumes it has read an
2372 old-format file, and it generates new data and writes a new file. This
2373 means that you can't go back to an older release without removing the
2374 file.
2375
2376PH/03 A redirect router that has both "unseen" and "one_time" set does not
2377 work if there are any delivery delays because "one_time" forces the

2380 these two options.

2384 entry if you want to know the details. The fix, however, neglected to
2385 consider the case when local delivery batching is involved. The test for
2386 "previously delivered" was not happening when checking to see if an
2387 address could be batched with a previous (undelivered) one; under
2388 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2389 address.

2390
2391PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2392 in its include files, and this causes problems building Exim.
2393
2394PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2395 header_syntax) but Exim was just ignoring anything given after a slash.
2396 In particular, this caused confusion with an attempt to use "verify =
2397 reverse_host_lookup/defer_ok". An error is now given when options are
2398 supplied for verify items that do not have them. (Maybe reverse_host_
2399 lookup should have a defer_ok option, but that's a different point.)
2400
2401PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2402 defined by RFC 821) to 2048, because there were problems with some AUTH
2403 commands, and RFC 1869 says the size should be increased for extended
2404 SMTP commands that take arguments.

2451PH/19 When an Exim process that is running as root has to create an Exim log
2452 file, it does so in a subprocess that runs as exim:exim so as to get the
2453 ownership right at creation (otherwise, other Exim processes might see
2454 the file with the wrong ownership). There was no test for failure of this
2455 fork() call, which would lead to the process getting stuck as it waited
2456 for a non-existent subprocess. Forks do occasionally fail when resources
2457 run out. I reviewed all the other calls to fork(); they all seem to check
2458 for failure.

PH
2460PH/20 When checking for unexpected SMTP input at connect time (before writing
2461 the banner), Exim was not dealing correctly with a non-positive return
2462 from the read() function. If the client had disconnected by this time,
2463 the result was a log entry for a synchronization error with an empty
2464 string after "input=" when read() returned zero. If read() returned -1
2465 (an event I could not check), uninitialized data bytes were printed.

c5ddb310
PH
2477PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2478 hadn't been configured. The fix is from Juergen Kreileder, who
2479 understands it better than I do:
2480
2481 "Here's what I see happening with three configured cyrus_sasl
2482 authenticators configured (plain, login, cram-md5):
2483
2484 On startup auth_cyrus_sasl_init() gets called for each of these.
2485 This means three calls to sasl_listmech() without a specified mech_list.
2486 => SASL tests which mechs of all available mechs actually work
2487 => three warnings about OTP not working
2488 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2489
2490 With the patch, sasl_listmech() also gets called three times. But now
2491 SASL's mech_list option is set to the server_mech specified in the the
2492 authenticator. Or in other words, the answer from sasl_listmech()
2493 gets limited to just the mech you're testing for (which is different
2494 for each call.)
2495 => the return list contains just 'plain' or 'login', 'cram-md5' or
2496 nothing depending on the value of ob->server_mech.
2497
2498 I've just tested the patch: Authentication still works fine,
2499 unavailable mechs specified in the exim configuration are still
2500 caught, and the auth.log warnings about OTP are gone."

d7174846
PH
2564PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2565 the grounds that routing the same address twice would always produce the
2566 same answer. This might have been true once, but it is certainly no
2567 longer true now. Routing a child address may depend on the previous
2568 routing that produced that child. Some complicated redirection strategies
2569 went wrong when messages had multiple recipients, and made Exim's
2570 behaviour dependent on the order in which the addresses were given.
2571
2572 I have moved the duplicate checking until after the routing is complete.
2573 Exim scans the addresses that are assigned to local and remote
2574 transports, and removes any duplicates. This means that more work will be
2575 done, as duplicates will always all be routed, but duplicates are
2576 presumably rare, so I don't expect this is of any significance.
2577
2578 For deliveries to pipes, files, and autoreplies, the duplicate checking
2579 still happens during the routing process, since they are not going to be
2580 routed further.

2621PH/45 In a pipe transport, although a timeout while waiting for the pipe

2624 successful delivery. Such timeouts include transport filter timeouts. For
2625 consistency with the overall process timeout, these timeouts are now
2626 treated as errors, giving rise to delivery failures by default. However,
2627 there is now a new Boolean option for the pipe transport called
2628 timeout_defer, which, if set TRUE, converts the failures into defers for
2629 both kinds of timeout. A transport filter timeout is now identified in

2639A note about Exim versions 4.44 and 4.50
2640----------------------------------------
2641
2642Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2643changes of various kinds. As a consequence, a big documentation update was
2644needed. This delayed the release for rather longer than seemed good, especially
2645in the light of a couple of (minor) security issues. Therefore, the changes
2646that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2647release. So 4.44 and 4.50 are in effect two different branches that both start
2648from 4.43.
2649
2650I have left the 4.50 change log unchanged; it contains all the changes since
26514.43. The change log for 4.44 is below; many of its items are identical to
2652those for 4.50. This seems to be the most sensible way to preserve the
2653historical information.

2671 5. There are several places where Exim runs a non-Exim command in a
2672 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2673 was being done only for the command run by the queryprogram router. It is
2674 now done for all such subprocesses. The other cases are: ${run, transport
2675 filters, and the commands run by the lmtp and pipe transports.

2680 descriptors. Exim was using setrlimit() to set 1000 as a large value
2681 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2682 systems. I've change it so that if it can't get 1000, it tries for 256.

2731
273223. When checking ignore_target_hosts for an ipliteral router, no host name was
2733 being passed; this would have caused $sender_host_name to have been used if
2734 matching the list had actually called for a host name (not very likely,
2735 since this list is usually IP addresses). A host name is now passed as
2736 "[x.x.x.x]".

2741
274225. Narrowed the window for a race in the daemon that could cause it to ignore

2757 subject address (from a bounce message) matched only if the pattern was an
2758 empty string. Non-empty patterns were not even tested. This was the wrong
2759 because it is perfectly reasonable to use an empty address as part of a
2760 database query. An empty address is now tested by patterns that are
2761 lookups. However, all the other forms of pattern expect the subject to
2762 contain a local part and a domain, and therefore, for them, an empty
2763 address still always fails if the pattern is not itself empty.

2775 such as real names; it was not keeping to the 75-character limit for
2776 encoded words that the RFC imposes. It now respects the limit, and
2777 generates multiple encoded words if necessary. To be on the safe side, I
2778 have increased the buffer size for the ${rfc2047: expansion operator from
2779 1024 to 2048 bytes.
2780
063b1e99
PH
278133. It is now permitted to omit both strings after an "if" condition; if the
2782 condition is true, the result is "true". As before, when the second string
2783 is omitted, a false condition yields an empty string. This makes it less
2784 cumbersome to write custom ACL and router conditions.
2785
652e1b65
PH
278634. Failure to deliver a bounce message always caused it to be frozen, even if
2787 there was an errors_to setting on the router. The errors_to setting is now
2788 respected.
2789
6f0c9a4f
PH
279035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2791 canonical form (fully expanded) before being placed in
2792 $sender_host_address.
2793
33397d19
PH
279436. The table in the code that translates DNS record types into text (T_A to
2795 "A" for instance) was missing entries for NS and CNAME. It is just possible
2796 that this could have caused confusion if both these types were looked up
2797 for the same domain, because the text type is used as part of Exim's
2798 per-process caching. But the chance of anyone hitting this buglet seems
2799 very small.
2800
7bb56e1f
PH
280137. The dnsdb lookup has been extended in a number of ways.
2802
2803 (1) There is a new type, "zns", which walks up the domain tree until it
2804 finds some nameserver records. It should be used with care.
2805
ea3bc19b
PH
2806 (2) There is a new type, "mxh", which is like "mx" except that it returns
2807 just the host names, not the priorities.
2808
2809 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2810 looked up. The behaviour when one of the lookups defers can be
2811 controlled by a keyword.
7bb56e1f 2812
ea3bc19b 2813 (4) It is now possible to specify the separator character for use when
7bb56e1f 2814 multiple records are returned.
33397d19 2815
0bcb2a0e
PH
281638. The dnslists ACL condition has been extended: it is now possible to supply
2817 a list of IP addresses and/or domains to be looked up in a particular DNS
2818 domain.
2819
2ac0e484
PH
282039. Added log_selector=+queue_time_overall.
2821
4e1fde53
PH
282240. When running the queue in the test harness, wait just a tad after forking a
2823 delivery process, to get repeatability of debugging output.
2824
de365ded
PH
282541. Include certificate and key file names in error message when GnuTLS fails
2826 to set them up, because the GnuTLS error message doesn't include the name
2827 of the failing file when there is a problem reading it.
2828
f05da2e8
PH
282942. Allow both -bf and -bF in the same test run.

d6453af2
PH
283143. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
2832
f7b63901
PH
283344. The "Exiscan patch" is now merged into the mainline Exim source.
2834
283545. Sometimes the final signoff response after QUIT could fail to get
2836 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2837 < 0 before doing a fflush(). This bug looks as though it goes back to the
2838 introduction of TLS in release 3.20, but "sometimes" must have been rare
2839 because the tests only now provoked it.
2840
a444213a
PH
284146. Reset the locale to "C" after calling embedded Perl, in case it was changed
2842 (this can affect the format of dates).
2843
0ec020ea
PH
284447. exim_tidydb, when checking for the continued existence of a message for
2845 which it has found a message-specific retry record, was not finding
2846 messages that were in split spool directories. Consequently, it was
2847 deleting retry records that should have stayed in existence.
2848
b1206957
PH
284948. Steve fixed some bugs in eximstats.
2850
285149. The SPA authentication driver was not abandoning authentication and moving
2852 on to the next authenticator when an expansion was forced to fail,
2853 contradicting the general specification for all authenticators. Instead it
2854 was generating a temporary error. It now behaves as specified.
2855
26dd5a95
PH
285650. The default ordering of permitted cipher suites for GnuTLS was pessimal
2857 (the order specifies the preference for clients). The order is now AES256,
2858 AES128, 3DES, ARCFOUR128.
2859

PH
286051. Small patch to Sieve code - explicitly set From: when generating an
2861 autoreply.
2862
1c5466b9
PH
286352. Exim crashed if a remote delivery caused a very long error message to be
2864 recorded - for instance if somebody sent an entire SpamAssassin report back
2865 as a large number of 550 error lines. This bug was coincidentally fixed by
2866 increasing the size of one of Exim's internal buffers (big_buffer) that
2867 happened as part of the Exiscan merge. However, to be on the safe side, I
2868 have made the code more robust (and fixed the comments that describe what
2869 is going on).
2870
55ee9ee3
PH
287153. Now that there can be additional text after "Completed" in log lines (if
2872 the queue_time_overall log selector is set), a one-byte patch to exigrep
2873 was needed to allow it to recognize "Completed" as not the last thing in
2874 the line.
2875
d38f8232
PH
287654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2877 patch that reportedly fixes this has been added. I am not expert enough to
2878 create a test for it. This is what the patch creator wrote:
2879
2880 "I found a little strange behaviour of ldap code when working with
2881 Windows 2003 AD Domain, where users was placed in more than one
2882 Organization Units. When I tried to give exim partial DN, the exit code
2883 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2884 But simultaneously result of request was absolutely normal ldap result,
2885 so I produce this patch..."
2886
3295e65b
PH
2887 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2888 REFERENCE, so I have modified the code to exclude the patch when that macro
2889 is not defined.
2890
7102e136
PH
289155. Some experimental protocols are using DNS PTR records for new purposes. The
2892 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2893 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2894 leaves it alone. Component reversal etc. now happens only for IP addresses.
ea3a6f44 2895 CAN-2005-0021
7102e136 2896

PH
289756. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
2898
c2bcbe20
PH
289957. Double the size of the debug message buffer (to 2048) so that more of very
2900 long debug lines gets shown.
2901
18ce445d
PH
290258. The exicyclog utility now does better if the number of log files to keep
2903 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
2904
1f5b4c3d
PH
290559. Two changes related to the smtp_active_hostname option:
2906
2907 (1) $smtp_active_hostname is now available as a variable.
2908 (2) The default for smtp_banner uses $smtp_active_hostname instead
2909 of $primary_hostname.
2910
b975ba52
PH
291160. The host_aton() function is supposed to be passed a string that is known
2912 to be a valid IP address. However, in the case of IPv6 addresses, it was
2913 not checking this. This is a hostage to fortune. Exim now panics and dies
2914 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2915 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2916 components; fortuitously, this particular loophole had already been fixed
2917 by change 4.50/55 above.
2918
2919 If there are any other similar loopholes, the new check in host_aton()
2920 itself should stop them being exploited. The report I received stated that
2921 data on the command line could provoke the exploit when Exim was running as
2922 exim, but did not say which command line option was involved. All I could
2923 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2924 running as the user.
ea3a6f44 2925 CAN-2005-0021
85b87bc2
PH
2926
292761. There was a buffer overflow vulnerability in the SPA authentication code
2928 (which came originally from the Samba project). I have added a test to the
2929 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 2930 CAN-2005-0022
b975ba52 2931
17ffcae7
PH
293262. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
2933 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
2934
d95f9fdb
PH
293563. The daemon start-up calls getloadavg() while still root for those OS that
2936 need the first call to be done as root, but it missed one case: when
2937 deliver_queue_load_max is set with deliver_drop_privilege. This is
2938 necessary for the benefit of the queue runner, because there is no re-exec
2939 when deliver_drop_privilege is set.
2940
86b8287f
PH
294164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
2942 This has been fixed.
2943
60dc5e56
PH
294465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2945 was in use, was not putting the data itself into the right store pool;
2946 consequently, it could be overwritten for a subsequent message in the same
2947 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2948 the caching.)
2949
533244af
PH
295066. Added hosts_max_try_hardlimit to the smtp transport, default 50.
2951
a5a28604
PH
295267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2953 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2954 the function were treating the return as a boolean value, which happened to
2955 work because 0=false and not-0=true, but is not correct code.
2956
7e634d24
PH
295768. The host_aton() function was not handling scoped IPv6 addresses (those
2958 with, for example, "%eth0" on the end) correctly.
2959
3e11c26b
PH
296069. Fixed some compiler warnings in acl.c for the bitmaps specified with
2961 negated items (that is, ~something) in unsigned ints. Some compilers
2962 apparently mutter when there is no cast.
2963
6729cf78
PH
296470. If an address verification called from an ACL failed, and did not produce a
2965 user-specific message (i.e. there was only a "system" message), nothing was
2966 put in $acl_verify_message. In this situation, it now puts the system
2967 message there.
2968
00f00ca5
PH
296971. Change 4.23/11 added synchronization checking at the start of an SMTP
2970 session; change 4.31/43 added the unwanted input to the log line - except
2971 that it did not do this in the start of session case. It now does.
2972
c9bdd01c
PH
297372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2974 This is wrong and can cause the other end to generate a synchronization
2975 error if it is another Exim or anything else that does the synchronization
2976 check. A QUIT command is no longer sent after a timeout.
2977
d43194df
PH
297873. $host_lookup_deferred has been added, to make it easier to detect DEFERs
2979 during host lookups.
2980
fe5b5d0b
PH
298174. The defer_ok option of callout verification was not working if it was used
2982 when verifying addresses in header lines, that is, for this case:
2983
2984 verify = header_sender/callout=defer_ok
2985
76a2d7ba
PH
298675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2987 those file descriptors could be used for SMTP connections. If anything
2988 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2989 could be sent to the SMTP client, causing chaos. The daemon now opens
2990 stdin, stdout, and stderr to /dev/null when it puts itself into the
2991 background.
2992
299376. Arrange for output from Perl's "warn" command to be written to Exim's main
2994 log by default. The user can override this with suitable Perl magic.
2995
04f7d5b9
PH
299677. The use of log_message on a "discard" ACL verb, which is supposed to add to
2997 the log message when discard triggers, was not working for the DATA ACL or
2998 for the non-SMTP ACL.
2999
bc60667e
PH
300078. Error message wording change in sieve.c.
3001
bb6e88ff
PH
300279. If smtp_accept_max_per_host was set, the number of connections could be
3003 restricted to fewer than expected, because the daemon was trying to set up
3004 a new connection before checking whether the processes handling previous
3005 connections had finished. The check for completed processes is now done
3006 earlier. On busy systems, this bug wouldn't be noticed because something
3007 else would have woken the daemon, and it would have reaped the completed
3008 process earlier.
3009
1e70f85b
PH
301080. If a message was submitted locally by a user whose login name contained one
3011 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3012 It caused a spool format error. I have fixed the spool reading code. A
3013 related problem was that the "from" clause in the Received: line became
3014 illegal because of the space(s). It is now covered by ${quote_local_part.
3015
301681. Included the latest eximstats from Steve (adds average sizes to HTML Top
3017 tables).

3030----------------------------------------------------
3031See the note above about the 4.44 and 4.50 releases.
3032----------------------------------------------------
3033
3034
3035Exim version 4.44
3036-----------------
3037
3038 1. Change 4.43/35 introduced a bug that caused file counts to be
3039 incorrectly computed when quota_filecount was set in an appendfile
3040 transport
3041
3042 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3043 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3044 place.
3045
3046 3. Give more explanation in the error message when the command for a transport
3047 filter fails to execute.
3048
3049 4. There are several places where Exim runs a non-Exim command in a
3050 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3051 was being done only for the command run by the queryprogram router. It is
3052 now done for all such subprocesses. The other cases are: ${run, transport
3053 filters, and the commands run by the lmtp and pipe transports.
3054
3055 5. Some older OS have a limit of 256 on the maximum number of file
3056 descriptors. Exim was using setrlimit() to set 1000 as a large value
3057 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3058 systems. I've change it so that if it can't get 1000, it tries for 256.
3059
3060 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3061 was an oversight, and furthermore, ever since the addition of extra
3062 controls (e.g. 4.43/32), the checks on when to allow different forms of
3063 "control" were broken. There should now be diagnostics for all cases when a
3064 control that does not make sense is encountered.
3065
3066 7. $recipients is now available in the predata ACL (oversight).
3067
3068 8. Tidy the search cache before the fork to do a delivery from a message
3069 received from the command line. Otherwise the child will trigger a lookup
3070 failure and thereby defer the delivery if it tries to use (for example) a
3071 cached ldap connection that the parent has called unbind on.
3072
3073 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3074 of $address_data from the recipient verification was clobbered by the
3075 sender verification.
3076
307710. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3078 was its contents. (It was OK if the option was not defined at all.)
3079
308011. A "Completed" log line is now written for messages that are removed from
3081 the spool by the -Mrm option.
3082
308312. $host_address is now set to the target address during the checking of
3084 ignore_target_hosts.
3085
308613. When checking ignore_target_hosts for an ipliteral router, no host name was
3087 being passed; this would have caused $sender_host_name to have been used if
3088 matching the list had actually called for a host name (not very likely,
3089 since this list is usually IP addresses). A host name is now passed as
3090 "[x.x.x.x]".
3091
309214. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3093 code that specifies a non-restarting handler (typically sigaction() in
3094 modern systems) in an attempt to fix a rare and obscure crash bug.
3095
309615. Narrowed the window for a race in the daemon that could cause it to ignore
3097 SIGCHLD signals. This is not a major problem, because they are used only to
3098 wake it up if nothing else does.
3099
310016. A malformed maildirsize file could cause Exim to calculate negative values
3101 for the mailbox size or file count. Odd effects could occur as a result.
3102 The maildirsize information is now recalculated if the size or filecount
3103 end up negative.
3104
310517. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3106 support for a long time. Removed HAVE_SYS_VFS_H.
3107
ea3a6f44 310818. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3109
311019. Allow an empty sender to be matched against a lookup in an address list.
3111 Previously the only cases considered were a regular expression, or an
3112 empty pattern.
3113
311420. Exim went into a mad DNS lookup loop when doing a callout where the
3115 host was specified on the transport, if the DNS lookup yielded more than
3116 one IP address.
3117
ea3a6f44
NM
311821. The RFC2047 encoding function was originally intended for short strings
3119 such as real names; it was not keeping to the 75-character limit for
3120 encoded words that the RFC imposes. It now respects the limit, and
3121 generates multiple encoded words if necessary. To be on the safe side, I
3122 have increased the buffer size for the ${rfc2047: expansion operator from
3123 1024 to 2048 bytes.
bbe902f0 3124
ea3a6f44
NM
312522. Failure to deliver a bounce message always caused it to be frozen, even if
3126 there was an errors_to setting on the router. The errors_to setting is now
3127 respected.
bbe902f0
PH
3128
312923. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3130 canonical form (fully expanded) before being placed in
3131 $sender_host_address.
3132
313324. Updated eximstats to version 1.33
3134
ea3a6f44
NM
313525. Include certificate and key file names in error message when GnuTLS fails
3136 to set them up, because the GnuTLS error message doesn't include the name
3137 of the failing file when there is a problem reading it.
bbe902f0
PH
3138
313926. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3140 As per change 25.
bbe902f0 3141
ea3a6f44
NM
314227. Reset the locale to "C" after calling embedded Perl, in case it was changed
3143 (this can affect the format of dates).
bbe902f0 3144
ea3a6f44
NM
314528. exim_tidydb, when checking for the continued existence of a message for
3146 which it has found a message-specific retry record, was not finding
3147 messages that were in split spool directories. Consequently, it was
3148 deleting retry records that should have stayed in existence.
bbe902f0
PH
3149
315029. eximstats updated to version 1.35
3151 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3152 1.35 - bugfix such that pie charts by volume are generated correctly

315430. The SPA authentication driver was not abandoning authentication and moving

3170 happened as part of the Exiscan merge. However, to be on the safe side, I
3171 have made the code more robust (and fixed the comments that describe what
3172 is going on).

317433. Some experimental protocols are using DNS PTR records for new purposes. The
3175 keys for these records are domain names, not reversed IP addresses. The
3176 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3177 leaves it alone. Component reversal etc. now happens only for IP addresses.

318034. The host_aton() function is supposed to be passed a string that is known
3181 to be a valid IP address. However, in the case of IPv6 addresses, it was
3182 not checking this. This is a hostage to fortune. Exim now panics and dies
3183 if the condition is not met. A case was found where this could be provoked
3184 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3185 components; fortuitously, this particular loophole had already been fixed
3186 by change 4.50/55 or 4.44/33 above.
3187
3188 If there are any other similar loopholes, the new check in host_aton()
3189 itself should stop them being exploited. The report I received stated that
3190 data on the command line could provoke the exploit when Exim was running as
3191 exim, but did not say which command line option was involved. All I could
3192 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3193 running as the user.

319635. There was a buffer overflow vulnerability in the SPA authentication code
3197 (which came originally from the Samba project). I have added a test to the
3198 spa_base64_to_bits() function which I hope fixes it.

320136. The daemon start-up calls getloadavg() while still root for those OS that
3202 need the first call to be done as root, but it missed one case: when
3203 deliver_queue_load_max is set with deliver_drop_privilege. This is
3204 necessary for the benefit of the queue runner, because there is no re-exec
3205 when deliver_drop_privilege is set.

320737. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3208 was in use, was not putting the data itself into the right store pool;
3209 consequently, it could be overwritten for a subsequent message in the same
3210 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3211 the caching.)

321338. Sometimes the final signoff response after QUIT could fail to get
3214 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3215 < 0 before doing a fflush(). This bug looks as though it goes back to the
3216 introduction of TLS in release 3.20, but "sometimes" must have been rare
3217 because the tests only now provoked it.

3220Exim version 4.43
3221-----------------
3222
3223 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3224 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3225 Now it returns an integer. A number of calls were still expecting a T/F
3226 return. Fortuitously, in all cases, the tests worked in OK situations,
3227 which is the norm. However, things would have gone wrong on any write
3228 failures on the smtp file descriptor. This function is used when sending
3229 messages over SMTP and also when doing verify callouts.
3230
3231 2. When Exim is called to do synchronous delivery of a locally submitted
3232 message (the -odf or -odi options), it no longer closes stderr before doing
3233 the delivery.
3234
3235 3. Implemented the mua_wrapper option.
3236
3237 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3238
3239 5. Implemented the functions header_remove(), header_testname(),
3240 header_add_at_position(), and receive_remove_recipient(), and exported them
3241 to local_scan().
3242
3243 6. If an ACL "warn" statement specified the addition of headers, Exim already
3244 inserted X-ACL-Warn: at the start if there was no header name. However, it
3245 was not making this test for the second and subsequent header lines if
3246 there were newlines in the string. This meant that an invalid header could
3247 be inserted if Exim was badly configured.
3248
3249 7. Allow an ACL "warn" statement to add header lines at the start or after all
3250 the Received: headers, as well as at the end.
3251
3252 8. Added the rcpt_4xx retry error code.
3253
3254 9. Added postmaster_mailfrom=xxx to callout verification option.
3255
325610. Added mailfrom=xxxx to the callout verification option, for verify=
3257 header_sender only.
3258
325911. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3260 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3261
326212. Inserted some casts to stop certain compilers warning when using pointer
3263 differences as field lengths or precisions in printf-type calls (mostly
3264 affecting debugging statements).
3265
326613. Added optional readline() support for -be (dynamically loaded).
3267
326814. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3269 same clock tick as a message's arrival, so that its received time was the
3270 same as the "first fail" time on the retry record, and that message
3271 remained on the queue past the ultimate address timeout, every queue runner
3272 would try a delivery (because it was past the ultimate address timeout) but
3273 after another failure, the ultimate address timeout, which should have then
3274 bounced the address, did not kick in. This was a "< instead of <=" error;
3275 in most cases the first failure would have been in the next clock tick
3276 after the received time, and all would be well.
3277
327815. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3279 being recognized when the domain list was tested by the match_domain
3280 condition in an expansion string.
3281
328216. Added the ${str2b64: operator.
3283
328417. Exim was always calling setrlimit() to set a large limit for the number of
3285 processes, without checking whether the existing limit was already
3286 adequate. (It did check for the limit on file descriptors.) Furthermore,
3287 errors from getrlimit() and setrlimit() were being ignored. Now they are
3288 logged to the main and panic logs, but Exim does carry on, to try to do its
3289 job under whatever limits there are.
3290
329118. Imported PCRE 5.0.
3292
329319. Trivial typo in log message " temporarily refused connection" (the leading
3294 space).
3295
329620. If the log selector return_path_on_delivery was set and an address was
3297 redirected to /dev/null, the delivery process crashed because it assumed
3298 that a return path would always be set for a "successful" delivery. In this
3299 case, the whole delivery is bypassed as an optimization, and therefore no
3300 return path is set.
3301
330221. Internal re-arrangement: the function for sending a challenge and reading
3303 a response while authentication was assuming a zero-terminated challenge
3304 string. It's now changed to take a pointer and a length, to allow for
3305 binary data in such strings.
3306
330722. Added the cyrus_sasl authenticator (code supplied by MBM).
3308
330923. Exim was not respecting finduser_retries when seeking the login of the
3310 uid under which it was called; it was always trying 10 times. (The default
3311 setting of finduser_retries is zero.) Also, it was sleeping after the final
3312 failure, which is pointless.
3313
331424. Implemented tls_on_connect_ports.
3315
331625. Implemented acl_smtp_predata.
3317
331826. If the domain in control=submission is set empty, Exim assumes that the
3319 authenticated id is a complete email address when it generates From: or
3320 Sender: header lines.
3321
332227. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3323 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3324 chown and chgrp in /bin and hostname in /usr/bin.
3325
332628. Exim was keeping the "process log" file open after each use, just as it
3327 does for the main log. This opens the possibility of it remaining open for
3328 long periods when the USR1 signal hits a daemon. Occasional processlog
3329 errors were reported, that could have been caused by this. Anyway, it seems
3330 much more sensible not to leave this file open at all, so that is what now
3331 happens.
3332
333329. The long-running daemon process does not normally write to the log once it
3334 has entered its main loop, and it closes the log before doing so. This is
3335 so that log files can straightforwardly be renamed and moved. However,
3336 there are a couple of unusual error situations where the daemon does write
3337 log entries, and I had neglected to close the log afterwards.
3338
333930. The text of an SMTP error response that was received during a remote
3340 delivery was being truncated at 512 bytes. This is too short for some of
3341 the long messages that one sometimes sees. I've increased the limit to
3342 1024.
3343
334431. It is now possible to make retry rules that apply only when a message has a
3345 specific sender, in particular, an empty sender.
3346
334732. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3348 it possible to be selective about when SMTP synchronization is enforced.
3349
335033. Added "control = caseful_local_part" and "control = "caselower_local_part".
3351
335232. Implemented hosts_connection_nolog.
3353
335433. Added an ACL for QUIT.
3355
335634. Setting "delay_warning=" to disable warnings was not working; it gave a
3357 syntax error.
3358
335935. Added mailbox_size and mailbox_filecount to appendfile.
3360
336136. Added control = no_multiline_responses to ACLs.
3362
336337. There was a bug in the logic of the code that waits for the clock to tick
3364 in the case where the clock went backwards by a substantial amount such
3365 that the microsecond fraction of "now" was more than the microsecond
3366 fraction of "then" (but the whole seconds number was less).
3367
336838. Added support for the libradius Radius client library this is found on
3369 FreeBSD (previously only the radiusclient library was supported).
3370
3371
3372Exim version 4.42
3373-----------------
3374
3375 1. When certain lookups returned multiple values in the form name=value, the
3376 quoting of the values was not always being done properly. Specifically:
3377 (a) If the value started with a double quote, but contained no whitespace,
3378 it was not quoted.
3379 (b) If the value contained whitespace other than a space character (i.e.
3380 tabs or newlines or carriage returns) it was not quoted.
3381 This fix has been applied to the mysql and pgsql lookups by writing a
3382 separate quoting function and calling it from the lookup code. The fix
3383 should probably also be applied to nisplus, ibase and oracle lookups, but
3384 since I cannot test any of those, I have not disturbed their existing code.
3385
3386 2. A hit in the callout cache for a specific address caused a log line with no
3387 reason for rejecting RCPT. Now it says "Previous (cached) callout
3388 verification failure".
3389
3390 3. There was an off-by-one bug in the queryprogram router. An over-long
3391 return line was truncated at 256 instead of 255 characters, thereby
3392 overflowing its buffer with the terminating zero. As well as fixing this, I
3393 have increased the buffer size to 1024 (and made a note to document this).
3394
3395 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3396 when Exim is waiting for an SMTP response from a remote server, Exim
3397 restarts its select() call on the socket, thereby resetting its timeout.
3398 This is not a problem when such interrupts are rare. Somebody set up a cron
3399 job to run exiwhat every 2 minutes, which is less than the normal select()
3400 timeout (5 or 10 minutes). This meant that the select() timeout never
3401 kicked in because it was always reset. I have fixed this by comparing the
3402 time when an interrupt arrives with the time at the start of the first call
3403 to select(). If more time than the timeout has elapsed, the interrupt is
3404 treated as a timeout.
3405
3406 5. Some internal re-factoring in preparation for the addition of Sieve
3407 extensions (by MH). In particular, the "personal" test is moved to a
3408 separate function, and given an option for scanning Cc: and Bcc: (which is
3409 not set for Exim filters).
3410
3411 6. When Exim created an email address using the login of the caller as the
3412 local part (e.g. when creating a From: or Sender: header line), it was not
3413 quoting the local part when it contained special characters such as @.
3414
3415 7. Installed new OpenBSD configuration files.
3416
3417 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3418 try to make them clearer.
3419
3420 9. Callout options, other than the timeout value, were being ignored when
3421 verifying sender addresses in header lines. For example, when using
3422
3423 verify = header_sender/callout=no_cache
3424
3425 the cache was (incorrectly) being used.
3426
342710. Added a missing instance of ${EXE} to the exim_install script; this affects
3428 only the Cygwin environment.
3429
343011. When return_path_on_delivery was set as a log selector, if different remote
3431 addresses in the same message used different return paths and parallel
3432 remote delivery occurred, the wrong values would sometimes be logged.
3433 (Whenever a remote delivery process finished, the return path value from
3434 the most recently started remote delivery process was logged.)
3435
343612. RFC 3848 specifies standard names for the &q
