499 were called 'true' and it seems that C99 defines that as a reserved

521
6a3bceb1
PH
522PH/02 When an IPv6 address is converted to a string for single-key lookup
523 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
524 dots are used instead of colons so that keys in lsearch files need not
525 contain colons. This was done some time before quoting was made available
526 in lsearch files. However, iplsearch files do require colons in IPv6 keys
527 (notated using the quote facility) so as to distinguish them from IPv4
528 keys. This meant that lookups for IP addresses in host lists did not work
529 for iplsearch lookups.
530
531 This has been fixed by arranging for IPv6 addresses to be expressed with
532 colons if the lookup type is iplsearch. This is not incompatible, because
533 previously such lookups could never work.
534
535 The situation is now rather anomolous, since one *can* have colons in
536 ordinary lsearch keys. However, making the change in all cases is
537 incompatible and would probably break a number of configurations.

542MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
543 conversion specification without a maximum field width, thereby enabling
544 a rogue spamd server to cause a buffer overflow. While nobody in their
545 right mind would setup Exim to query an untrusted spamd server, an
546 attacker that gains access to a server running spamd could potentially
547 exploit this vulnerability to run arbitrary code as the Exim user.

MH
552MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
553 a directory entry by the name of the lookup key. Previously, if a
554 symlink pointed to a non-existing file or a file in a directory that
555 Exim lacked permissions to read, a lookup for a key matching that
556 symlink would fail. Now it is enough that a matching directory entry
557 exists, symlink or not. (Bugzilla 503.)

740PH/29 SMTP synchronization checks are implemented when a command is read -
741 there is a check that no more input is waiting when there shouldn't be

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

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

799PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
800 message are rejected with the same error (e.g. no authentication or bad
801 sender address), and a DATA command is nevertheless sent (as can happen
802 with PIPELINING or a stupid MUA), the error message that was given to the
803 RCPT commands is included in the rejection of the DATA command. This is
804 intended to be helpful for MUAs that show only the final error to their

58eb016e 819PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
820 the response to the final '.' that terminates a message, but only in the
821 case where the client has not sent further data following the '.'
822 (unfortunately, this is allowed). However, in many cases there won't be
823 any further data because there won't be any more messages to send. A call
824 to select() can be used: if it shows that the input is "ready", there is
825 either input waiting, or the socket has been closed. An attempt to read
826 the next input character can distinguish the two cases. Previously, Exim
58eb016e 827 would have sent an OK response which the client would never have see.

835Exim version 4.66
836-----------------
837
838PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
839 fixed by 4.65/MH/01 (is this a record?) are fixed:
840
841 (i) An empty string was always treated as zero by the numeric comparison
842 operators. This behaviour has been restored.
843
844 (ii) It is documented that the numeric comparison operators always treat
845 their arguments as decimal numbers. This was broken in that numbers
846 starting with 0 were being interpreted as octal.
847
848 While fixing these problems I realized that there was another issue that
849 hadn't been noticed. Values of message_size_limit (both the global option
850 and the transport option) were treated as octal if they started with 0.
851 The documentation was vague. These values are now always treated as
852 decimal, and I will make that clear in the documentation.

866PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
867 child addresses, Exim now panics and dies. Previously, because the count
868 is held in a short int, deliveries were likely to be lost. As such a
869 large number of recipients for a single message is ridiculous
870 (performance will be very, very poor), I have chosen to impose a limit
871 rather than extend the field.

877TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
878 leftover -K file (the existence of which was triggered by #402).

886
887TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

894 in the field name.

2b1c6e3a
PH
896PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
897 callout verification, Exim cached a "reject" for the entire domain. This
898 is correct for most verifications, but it is not correct for a recipient
899 verification with use_sender or use_postmaster set, because in that case
900 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
901 case of MAIL FROM:<> rejection from other early rejections (e.g.
902 rejection of HELO). When verifying a recipient using a non-null MAIL
903 address, the cache is ignored if it shows MAIL FROM:<> rejection.
904 Whatever the result of the callout, the value of the domain cache is
905 left unchanged (for any other kind of callout, getting as far as trying
906 RCPT means that the domain itself is ok).

940PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

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

14aa5a05 949PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 950 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
951 (a) The code assumed that strncpy() returns a negative number on buffer
952 overflow, which isn't the case. Replaced with Exim's string_format()
953 function.
954 (b) There were several signed/unsigned issues. I just did the minimum
955 hacking in of casts. There is scope for a larger refactoring.
956 (c) The code used strcasecmp() which is not a standard C function.
957 Replaced with Exim's strcmpic() function.
958 (d) The code set only $1; it now sets $auth1 as well.
959 (e) A simple test gave the error "authentication client didn't specify
960 service in request". It would seem that Dovecot has changed its
961 interface. Fortunately there's a specification; I followed it and
962 changed what the client sends and it appears to be working now.

967PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
968 address A is aliased to B and C, where B exists and C does not. Without
969 -v the output is "A verified" because verification stops after a
970 successful redirection if more than one address is generated. However,
971 with -v the child addresses are also verified. Exim was outputting "A
972 failed to verify" and then showing the successful verification for C,
973 with its parentage. It now outputs "B failed to verify", showing B's
974 parentage before showing the successful verification of C.

979
322050c2
PH
980PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
981 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
982 they consult the DNS. I had assumed they would set it the way they
983 wanted; and indeed my experiments on Linux seem to show that in some
984 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
985 To be on the safe side, however, I have now made the interface to
986 host_find_byname() similar to host_find_bydns(), with an argument
987 containing the DNS resolver options. The host_find_byname() function now
988 sets these options at its start, just as host_find_bydns() does. The smtp
989 transport options dns_qualify_single and dns_search_parents are passed to
990 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
991 of host_find_byname() use the default settings of RES_DEFNAMES
992 (qualify_single) but not RES_DNSRCH (search_parents).

994PH/17 Applied (a modified version of) Nico Erfurth's patch to make
995 spool_read_header() do less string testing, by means of a preliminary
996 switch on the second character of optional "-foo" lines. (This is
997 overdue, caused by the large number of possibilities that now exist.
998 Originally there were few.) While I was there, I also converted the
999 str(n)cmp tests so they don't re-test the leading "-" and the first
1000 character, in the hope this might squeeze out yet more improvement.

1002PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1003 flag allowing group syntax was set by the header_syntax check but not
1004 turned off, possible causing trouble later; (2) The flag was not being
1005 set at all for the header_verify test, causing "group"-style headers to
1006 be rejected. I have now set it in this case, and also caused header_
1007 verify to ignore an empty address taken from a group. While doing this, I
1008 came across some other cases where the code for allowing group syntax
1009 while scanning a header line wasn't quite right (mostly, not resetting
1010 the flag correctly in the right place). These bugs could have caused
1011 trouble for malformed header lines. I hope it is now all correct.

1013PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1015 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1016 but it didn't always do it. This confused somebody who was copying the
1017 code for some other use. I have removed all the tests.

PH
1019PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1020 feature that was used to support insecure browsers during the U.S. crypto
1021 embargo. It requires special client support, and Exim is probably the
1022 only MTA that supported it -- and would never use it because real RSA is
1023 always available. This code has been removed, because it had the bad
1024 effect of slowing Exim down by computing (never used) parameters for the
1025 RSA_EXPORT functionality.

1030 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1031 if the connection is using TLS or if the remote IP is the same as the
1032 local IP, and the "valid-client-cert option" if a client certificate has
1033 been verified.

1064
1065PH/30 Exim was sometimes attempting to deliver messages that had suffered
1066 address errors (4xx response to RCPT) over the same connection as other
1067 messages routed to the same hosts. Such deliveries are always "forced",
1068 so retry times are not inspected. This resulted in far too many retries
1069 for the affected addresses. The effect occurred only when there were more
1070 hosts than the hosts_max_try setting in the smtp transport when it had
1071 the 4xx errors. Those hosts that it had tried were not added to the list
1072 of hosts for which the message was waiting, so if all were tried, there
1073 was no problem. Two fixes have been applied:
1074
1075 (i) If there are any address or message errors in an SMTP delivery, none
1076 of the hosts (tried or untried) are now added to the list of hosts
1077 for which the message is waiting, so the message should not be a
1078 candidate for sending over the same connection that was used for a
1079 successful delivery of some other message. This seems entirely
1080 reasonable: after all the message is NOT "waiting for some host".
1081 This is so "obvious" that I'm not sure why it wasn't done
1082 previously. Hope I haven't missed anything, but it can't do any
1083 harm, as the worst effect is to miss an optimization.
1084
1085 (ii) If, despite (i), such a delivery is accidentally attempted, the
1086 routing retry time is respected, so at least it doesn't keep
1087 hammering the server.

1102PH/35 The error "getsockname() failed: connection reset by peer" was being
1103 written to the panic log as well as the main log, but it isn't really

1105 removed the panic log writing for the ECONNRESET error when getsockname()
1106 fails.

48c7f9e2
PH
1108PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1109 runs only) independently of the message's sender address. This meant
1110 that, if the 4xx error was in fact related to the sender, a different
1111 message to the same recipient with a different sender could confuse
1112 things. In particualar, this can happen when sending to a greylisting
1113 server, but other circumstances could also provoke similar problems.
1114 I have changed the default so that the retry time for these errors is now
1115 based a combination of the sender and recipient addresses. This change
1116 can be overridden by setting address_retry_include_sender=false in the
1117 smtp transport.

1385PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1387 Unfortunately, if there is a major crisis, such as a disk failure,
1388 tcp-wrappers gives "deny", whereas what one would like would be some
1389 kind of temporary error. A kludge has been added to help with this.
1390 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1391 554 error is used if errno is still zero or contains ENOENT (which occurs
1392 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1393 451 error is used.

1432 code found IPv4 interfaces correctly, but gave incorrect values for the
1433 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1434 that it would not match correctly against @[] and not recognize the IPv6
1435 addresses as local.

1478 autoreply, Exim could try to deliver to a non-existent relative file

1514 Instead, it always explicitly searches for A/AAAA records. This avoids
1515 major problems that occur when a DNS server includes only records of one
1516 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1517 fixed another bug: if SRV records were looked up and the corresponding
1518 address records were *not* found in the additional section, the port
1519 values from the SRV records were lost.

PH
1529PH/19 When calculating a retry time, Exim used to measure the "time since
1530 failure" by looking at the "first failed" field in the retry record. Now
1531 it does not use this if it is later than than the arrival time of the
1532 message. Instead it uses the arrival time. This makes for better
1533 behaviour in cases where some deliveries succeed, thus re-setting the
1534 "first failed" field. An example is a quota failure for a huge message
1535 when small messages continue to be delivered. Without this change, the
1536 "time since failure" will always be short, possible causing more frequent
1537 delivery attempts for the huge message than are intended.

PH
1634PH/42 The content-scanning code uses fopen() to create files in which to put
1635 message data. Previously it was not paying any attention to the mode of
1636 the files. Exim runs with umask(0) because the rest of the code creates
1637 files with open(), and sets the required mode explicitly. Thus, these
1638 files were ending up world-writeable. This was not a big issue, because,
1639 being within the spool directory, they were not world-accessible. I have
1640 created a function called modefopen, which takes an additional mode
1641 argument. It sets umask(777), creates the file, chmods it to the required
1642 mode, then resets the umask. All the relevant calls to fopen() in the
1643 content scanning code have been changed to use this function.

1654 received. Setting client_ignore_invalid_base64 true ignores these errors.
1655 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1656 they are received. Thus, the responses can be made to depend on the

1678PH/52 Two bugs concerned with error handling when the smtp transport is
1679 used in LMTP mode:
1680
1681 (i) Exim was not creating retry information for temporary errors given
1682 for individual recipients after the DATA command when the smtp transport
1683 was used in LMTP mode. This meant that they could be retried too
1684 frequently, and not timed out correctly.
1685
1686 (ii) Exim was setting the flag that allows error details to be returned
1687 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1688 recipients that were returned after the DATA command.
1689
1690PH/53 This is related to PH/52, but is more general: for any failing address,
1691 when detailed error information was permitted to be returned to the
1692 sender, but the error was temporary, then after the final timeout, only
1693 "retry timeout exceeded" was returned. Now it returns the full error as

1764PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1765 function verify_get_ident() calls ip_connect() to connect a socket, but
1766 if the "connect()" function timed out, ip_connect() used to close the
1767 socket. However, verify_get_ident() also closes the socket later, and in
1768 between Exim writes to the log, which may get opened at this point. When
1769 the socket was closed in ip_connect(), the log could get the same file
1770 descriptor number as the socket. This naturally causes chaos. The fix is
1771 not to close the socket in ip_connect(); the socket should be closed by
1772 the function that creates it. There was only one place in the code where
1773 this was missing, in the iplookup router, which I don't think anybody now
1774 uses, but I've fixed it anyway.

1798 (2) Treat a missing third argument of ${prvscheck as if it were an empty

1800
1801 (3) Reset the variables that are obtained from the first argument of
1802 ${prvscheck and used in the second argument before leaving the code,
1803 because their memory is reclaimed, so using them afterwards may do
1804 silly things.
1805
1806 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1807 one (it's much easier than Tom thought :-).

1831 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1832 not being looked up in the rDNS to get a host name, Exim was showing the
1833 IP address twice in Received: lines, even though the IP addresses were
1834 identical. For example:
1835
1836 Received: from [1.2.3.4] (helo=[1.2.3.4])
1837
1838 However, if the real host name was known, it was omitting the HELO data
1839 if it matched the actual IP address. This has been tidied up so that it
1840 doesn't show the same IP address twice.

1875 to another message, thes have all been changed to:

1932 addresses acquired from the DNS when checking that the found name did
1933 have the original IP as one of its addresses. Since any found IPv6
1934 addresses are likely to be in abbreviated form, the comparison could
1935 fail. Luckily, there already exists a function for doing the comparison
1936 by converting both addresses to binary, so now that is used instead of

2235 with the definition in sysexits.h (which is #included earlier).
2236 Fortunately, Exim does not actually use EX_OK. The code used to try to
2237 preserve the sysexits.h value, by assumimg that macro definitions were
2238 scanned for macro replacements. I have been disabused of this notion,
2239 so now the code just undefines EX_OK before #including unistd.h.

2244 This seems wrong - if the receiver was accepting one byte at a time it
2245 would take for ever. The timeout is now adjusted when this happens. It
2246 doesn't have to be particularly precise.

2382PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2383 specify a transport. However, if an address that was verified by such a
2384 router was the subject of a callout, Exim crashed because it tried to
2385 read the rcpt_include_affixes from the non-existent transport. Now it
2386 just assumes that the setting of that option is false. This bug was

2454
2455PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2456 that changes the way the GnuTLS parameters are stored in the cache file.
2457 The new format can be generated externally. For backward compatibility,
2458 if the data in the cache doesn't make sense, Exim assumes it has read an
2459 old-format file, and it generates new data and writes a new file. This
2460 means that you can't go back to an older release without removing the
2461 file.
2462
2463PH/03 A redirect router that has both "unseen" and "one_time" set does not
2464 work if there are any delivery delays because "one_time" forces the
2465 parent to be marked "delivered", so its unseen clone is never tried
2466 again. For this reason, Exim now forbids the simultaneous setting of
2467 these two options.

2472 consider the case when local delivery batching is involved. The test for
2473 "previously delivered" was not happening when checking to see if an
2474 address could be batched with a previous (undelivered) one; under
2475 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2476 address.

2481PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

2483 In particular, this caused confusion with an attempt to use "verify =
2484 reverse_host_lookup/defer_ok". An error is now given when options are
2485 supplied for verify items that do not have them. (Maybe reverse_host_

2541 the file with the wrong ownership). There was no test for failure of this
2542 fork() call, which would lead to the process getting stuck as it waited
2543 for a non-existent subprocess. Forks do occasionally fail when resources

2564PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

2566 understands it better than I do:
2567
2568 "Here's what I see happening with three configured cyrus_sasl
2569 authenticators configured (plain, login, cram-md5):
2570
2571 On startup auth_cyrus_sasl_init() gets called for each of these.
2572 This means three calls to sasl_listmech() without a specified mech_list.
2573 => SASL tests which mechs of all available mechs actually work
2574 => three warnings about OTP not working
2575 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2576
2577 With the patch, sasl_listmech() also gets called three times. But now
2578 SASL's mech_list option is set to the server_mech specified in the the
2579 authenticator. Or in other words, the answer from sasl_listmech()
2580 gets limited to just the mech you're testing for (which is different
2581 for each call.)
2582 => the return list contains just 'plain' or 'login', 'cram-md5' or
2583 nothing depending on the value of ob->server_mech.
2584

PH
2651PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2652 the grounds that routing the same address twice would always produce the
2653 same answer. This might have been true once, but it is certainly no
2654 longer true now. Routing a child address may depend on the previous
2655 routing that produced that child. Some complicated redirection strategies
2656 went wrong when messages had multiple recipients, and made Exim's
2657 behaviour dependent on the order in which the addresses were given.
2658
2659 I have moved the duplicate checking until after the routing is complete.
2660 Exim scans the addresses that are assigned to local and remote
2661 transports, and removes any duplicates. This means that more work will be
2662 done, as duplicates will always all be routed, but duplicates are
2663 presumably rare, so I don't expect this is of any significance.
2664
2665 For deliveries to pipes, files, and autoreplies, the duplicate checking
2666 still happens during the routing process, since they are not going to be

2714 there is now a new Boolean option for the pipe transport called

2726A note about Exim versions 4.44 and 4.50
2727----------------------------------------
2728
2729Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2730changes of various kinds. As a consequence, a big documentation update was
2731needed. This delayed the release for rather longer than seemed good, especially
2732in the light of a couple of (minor) security issues. Therefore, the changes
2733that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2734release. So 4.44 and 4.50 are in effect two different branches that both start
2735from 4.43.
2736
2737I have left the 4.50 change log unchanged; it contains all the changes since
27384.43. The change log for 4.44 is below; many of its items are identical to
2739those for 4.50. This seems to be the most sensible way to preserve the
2740historical information.

2777 9. Added the /retain_sender option to "control=submission".
2778
5be20824
PH
277910. $recipients is now available in the predata ACL (oversight).
2780
eb2c0248
PH
278111. Tidy the search cache before the fork to do a delivery from a message
2782 received from the command line. Otherwise the child will trigger a lookup
2783 failure and thereby defer the delivery if it tries to use (for example) a
2784 cached ldap connection that the parent has called unbind on.
2785
2a3eea10
PH
278612. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2787 of $address_data from the recipient verification was clobbered by the
2788 sender verification.
2789
279013. The value of address_data from a sender verification is now available in
2791 $sender_address_data in subsequent conditions in the ACL statement.
2792
23c7ff99
PH
279314. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
2794
4deaf07d
PH
279515. Added a new option "connect=<time>" to callout options, to set a different
2796 connection timeout.
2797
926e1192
PH
279816. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
2799 was its contents. (It was OK if the option was not defined at all.)
2800
650edc6f
PH
280117. A "Completed" log line is now written for messages that are removed from
2802 the spool by the -Mrm option.
2803
2c7db3f5
PH
280418. New variables $sender_verify_failure and $recipient_verify_failure contain
2805 information about exactly what failed.
2806
3d235903
PH
280719. Added -dd to debug only the daemon process.
2808
7c7ad977
PH
280920. Incorporated Michael Haardt's patch to ldap.c for improving the way it
2810 handles timeouts, both on the server side and network timeouts. Renamed the
2811 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
2812
981756db
PH
281321. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
2814 It is now set to "smtps".
2815
d4eb88df
PH
281622. $host_address is now set to the target address during the checking of
2817 ignore_target_hosts.
2818
281923. When checking ignore_target_hosts for an ipliteral router, no host name was
2820 being passed; this would have caused $sender_host_name to have been used if
2821 matching the list had actually called for a host name (not very likely,
2822 since this list is usually IP addresses). A host name is now passed as
2823 "[x.x.x.x]".
2824
7d468ab8
PH
282524. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2826 code that specifies a non-restarting handler (typically sigaction() in
2827 modern systems) in an attempt to fix a rare and obscure crash bug.
2828
282925. Narrowed the window for a race in the daemon that could cause it to ignore
2830 SIGCHLD signals. This is not a major problem, because they are used only to
2831 wake it up if nothing else does.
2832
62c0818f
PH
283326. A malformed maildirsize file could cause Exim to calculate negative values
2834 for the mailbox size or file count. Odd effects could occur as a result.
2835 The maildirsize information is now recalculated if the size or filecount
2836 end up negative.
2837
26034054
PH
283827. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2839 support for a long time. Removed HAVE_SYS_VFS_H.
2840
af66f652
PH
284128. Installed the latest version of exipick from John Jetmore.
2842
90af77f4
PH
284329. In an address list, if the pattern was not a regular expression, an empty
2844 subject address (from a bounce message) matched only if the pattern was an
2845 empty string. Non-empty patterns were not even tested. This was the wrong
2846 because it is perfectly reasonable to use an empty address as part of a
2847 database query. An empty address is now tested by patterns that are
2848 lookups. However, all the other forms of pattern expect the subject to
2849 contain a local part and a domain, and therefore, for them, an empty
2850 address still always fails if the pattern is not itself empty.
2851
d8ef3577
PH
285230. Exim went into a mad DNS loop when attempting to do a callout where the
2853 host was specified on an smtp transport, and looking it up yielded more
2854 than one IP address.
2855
5cb8cbc6
PH
285631. Re-factored the code for checking spool and log partition space into a
2857 function that finds that data and another that does the check. The former
2858 is then used to implement four new variables: $spool_space, $log_space,
2859 $spool_inodes, and $log_inodes.
2860
14702f5b
PH
286132. The RFC2047 encoding function was originally intended for short strings
2862 such as real names; it was not keeping to the 75-character limit for
2863 encoded words that the RFC imposes. It now respects the limit, and
2864 generates multiple encoded words if necessary. To be on the safe side, I
2865 have increased the buffer size for the ${rfc2047: expansion operator from
2866 1024 to 2048 bytes.
2867
063b1e99
PH
286833. It is now permitted to omit both strings after an "if" condition; if the
2869 condition is true, the result is "true". As before, when the second string
2870 is omitted, a false condition yields an empty string. This makes it less
2871 cumbersome to write custom ACL and router conditions.
2872
652e1b65
PH
287334. Failure to deliver a bounce message always caused it to be frozen, even if
2874 there was an errors_to setting on the router. The errors_to setting is now
2875 respected.
2876
6f0c9a4f
PH
287735. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2878 canonical form (fully expanded) before being placed in
2879 $sender_host_address.
2880
33397d19
PH
288136. The table in the code that translates DNS record types into text (T_A to
2882 "A" for instance) was missing entries for NS and CNAME. It is just possible
2883 that this could have caused confusion if both these types were looked up
2884 for the same domain, because the text type is used as part of Exim's
2885 per-process caching. But the chance of anyone hitting this buglet seems
2886 very small.
2887
7bb56e1f
PH
288837. The dnsdb lookup has been extended in a number of ways.
2889
2890 (1) There is a new type, "zns", which walks up the domain tree until it
2891 finds some nameserver records. It should be used with care.
2892
ea3bc19b
PH
2893 (2) There is a new type, "mxh", which is like "mx" except that it returns
2894 just the host names, not the priorities.
2895
2896 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2897 looked up. The behaviour when one of the lookups defers can be
2898 controlled by a keyword.
7bb56e1f 2899
ea3bc19b 2900 (4) It is now possible to specify the separator character for use when
7bb56e1f 2901 multiple records are returned.
33397d19 2902
0bcb2a0e
PH
290338. The dnslists ACL condition has been extended: it is now possible to supply
2904 a list of IP addresses and/or domains to be looked up in a particular DNS
2905 domain.
2906
2ac0e484
PH
290739. Added log_selector=+queue_time_overall.
2908
4e1fde53
PH
290940. When running the queue in the test harness, wait just a tad after forking a
2910 delivery process, to get repeatability of debugging output.
2911
de365ded
PH
291241. Include certificate and key file names in error message when GnuTLS fails
2913 to set them up, because the GnuTLS error message doesn't include the name
2914 of the failing file when there is a problem reading it.
2915
f05da2e8
PH
291642. Allow both -bf and -bF in the same test run.
2917
d6453af2
PH
291843. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
2919
f7b63901
PH
292044. The "Exiscan patch" is now merged into the mainline Exim source.
2921
292245. Sometimes the final signoff response after QUIT could fail to get
2923 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2924 < 0 before doing a fflush(). This bug looks as though it goes back to the
2925 introduction of TLS in release 3.20, but "sometimes" must have been rare
2926 because the tests only now provoked it.
2927
a444213a
PH
292846. Reset the locale to "C" after calling embedded Perl, in case it was changed
2929 (this can affect the format of dates).
2930
0ec020ea
PH
293147. exim_tidydb, when checking for the continued existence of a message for
2932 which it has found a message-specific retry record, was not finding
2933 messages that were in split spool directories. Consequently, it was
2934 deleting retry records that should have stayed in existence.
2935
b1206957
PH
293648. Steve fixed some bugs in eximstats.
2937
293849. The SPA authentication driver was not abandoning authentication and moving
2939 on to the next authenticator when an expansion was forced to fail,
2940 contradicting the general specification for all authenticators. Instead it
2941 was generating a temporary error. It now behaves as specified.
2942
26dd5a95
PH
294350. The default ordering of permitted cipher suites for GnuTLS was pessimal
2944 (the order specifies the preference for clients). The order is now AES256,
2945 AES128, 3DES, ARCFOUR128.
2946
343b2385
PH
294751. Small patch to Sieve code - explicitly set From: when generating an
2948 autoreply.
2949
1c5466b9
PH
295052. Exim crashed if a remote delivery caused a very long error message to be
2951 recorded - for instance if somebody sent an entire SpamAssassin report back
2952 as a large number of 550 error lines. This bug was coincidentally fixed by
2953 increasing the size of one of Exim's internal buffers (big_buffer) that
2954 happened as part of the Exiscan merge. However, to be on the safe side, I
2955 have made the code more robust (and fixed the comments that describe what
2956 is going on).
2957
55ee9ee3
PH
295853. Now that there can be additional text after "Completed" in log lines (if
2959 the queue_time_overall log selector is set), a one-byte patch to exigrep
2960 was needed to allow it to recognize "Completed" as not the last thing in
2961 the line.
2962
d38f8232
PH
296354. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2964 patch that reportedly fixes this has been added. I am not expert enough to
2965 create a test for it. This is what the patch creator wrote:
2966
2967 "I found a little strange behaviour of ldap code when working with
2968 Windows 2003 AD Domain, where users was placed in more than one
2969 Organization Units. When I tried to give exim partial DN, the exit code
2970 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2971 But simultaneously result of request was absolutely normal ldap result,
2972 so I produce this patch..."
2973
3295e65b
PH
2974 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2975 REFERENCE, so I have modified the code to exclude the patch when that macro
2976 is not defined.
2977
7102e136
PH
297855. Some experimental protocols are using DNS PTR records for new purposes. The
2979 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2980 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2981 leaves it alone. Component reversal etc. now happens only for IP addresses.
ea3a6f44 2982 CAN-2005-0021
7102e136 2983
3ca0ba97
PH
298456. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
2985
c2bcbe20
PH
298657. Double the size of the debug message buffer (to 2048) so that more of very
2987 long debug lines gets shown.
2988
18ce445d
PH
298958. The exicyclog utility now does better if the number of log files to keep
2990 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
2991
1f5b4c3d
PH
299259. Two changes related to the smtp_active_hostname option:
2993
2994 (1) $smtp_active_hostname is now available as a variable.
2995 (2) The default for smtp_banner uses $smtp_active_hostname instead
2996 of $primary_hostname.
2997
b975ba52
PH
299860. The host_aton() function is supposed to be passed a string that is known
2999 to be a valid IP address. However, in the case of IPv6 addresses, it was
3000 not checking this. This is a hostage to fortune. Exim now panics and dies
3001 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3002 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3003 components; fortuitously, this particular loophole had already been fixed
3004 by change 4.50/55 above.
3005
3006 If there are any other similar loopholes, the new check in host_aton()
3007 itself should stop them being exploited. The report I received stated that
3008 data on the command line could provoke the exploit when Exim was running as
3009 exim, but did not say which command line option was involved. All I could
3010 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3011 running as the user.
ea3a6f44 3012 CAN-2005-0021
85b87bc2
PH
3013
301461. There was a buffer overflow vulnerability in the SPA authentication code
3015 (which came originally from the Samba project). I have added a test to the
3016 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3017 CAN-2005-0022
b975ba52 3018
17ffcae7
PH
301962. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3020 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3021
d95f9fdb
PH
302263. The daemon start-up calls getloadavg() while still root for those OS that
3023 need the first call to be done as root, but it missed one case: when
3024 deliver_queue_load_max is set with deliver_drop_privilege. This is
3025 necessary for the benefit of the queue runner, because there is no re-exec
3026 when deliver_drop_privilege is set.
3027
86b8287f
PH
302864. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3029 This has been fixed.
3030
60dc5e56
PH
303165. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3032 was in use, was not putting the data itself into the right store pool;
3033 consequently, it could be overwritten for a subsequent message in the same
3034 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3035 the caching.)
3036
533244af
PH
303766. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3038
a5a28604
PH
303967. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3040 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3041 the function were treating the return as a boolean value, which happened to
3042 work because 0=false and not-0=true, but is not correct code.
3043
7e634d24
PH
304468. The host_aton() function was not handling scoped IPv6 addresses (those
3045 with, for example, "%eth0" on the end) correctly.
3046
3e11c26b
PH
304769. Fixed some compiler warnings in acl.c for the bitmaps specified with
3048 negated items (that is, ~something) in unsigned ints. Some compilers
3049 apparently mutter when there is no cast.
3050
6729cf78
PH
305170. If an address verification called from an ACL failed, and did not produce a
3052 user-specific message (i.e. there was only a "system" message), nothing was
3053 put in $acl_verify_message. In this situation, it now puts the system
3054 message there.
3055
00f00ca5
PH
305671. Change 4.23/11 added synchronization checking at the start of an SMTP
3057 session; change 4.31/43 added the unwanted input to the log line - except
3058 that it did not do this in the start of session case. It now does.
3059
c9bdd01c
PH
306072. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3061 This is wrong and can cause the other end to generate a synchronization
3062 error if it is another Exim or anything else that does the synchronization
3063 check. A QUIT command is no longer sent after a timeout.
3064
d43194df
PH
306573. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3066 during host lookups.
3067
fe5b5d0b
PH
306874. The defer_ok option of callout verification was not working if it was used
3069 when verifying addresses in header lines, that is, for this case:
3070
3071 verify = header_sender/callout=defer_ok
3072
76a2d7ba
PH
307375. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3074 those file descriptors could be used for SMTP connections. If anything
3075 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3076 could be sent to the SMTP client, causing chaos. The daemon now opens
3077 stdin, stdout, and stderr to /dev/null when it puts itself into the
3078 background.
3079
308076. Arrange for output from Perl's "warn" command to be written to Exim's main
3081 log by default. The user can override this with suitable Perl magic.
3082
04f7d5b9
PH
308377. The use of log_message on a "discard" ACL verb, which is supposed to add to
3084 the log message when discard triggers, was not working for the DATA ACL or
3085 for the non-SMTP ACL.
3086
bc60667e
PH
308778. Error message wording change in sieve.c.
3088
bb6e88ff
PH
308979. If smtp_accept_max_per_host was set, the number of connections could be
3090 restricted to fewer than expected, because the daemon was trying to set up
3091 a new connection before checking whether the processes handling previous
3092 connections had finished. The check for completed processes is now done
3093 earlier. On busy systems, this bug wouldn't be noticed because something
3094 else would have woken the daemon, and it would have reaped the completed
3095 process earlier.
3096
1e70f85b
PH
309780. If a message was submitted locally by a user whose login name contained one
3098 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3099 It caused a spool format error. I have fixed the spool reading code. A
3100 related problem was that the "from" clause in the Received: line became
3101 illegal because of the space(s). It is now covered by ${quote_local_part.
3102
310381. Included the latest eximstats from Steve (adds average sizes to HTML Top
3104 tables).
3105
4e01f9d6
PH
310682. Updated OS/Makefile-AIX as per message from Mike Meredith.

310883. Patch from Sieve maintainer to fix unterminated string problem in
3109 "vacation" handling.
3110

PH
311184. Some minor changes to the Linux configuration files to help with other
3112 OS variants using glibc.
3113

3117----------------------------------------------------
3118See the note above about the 4.44 and 4.50 releases.
3119----------------------------------------------------
3120
3121
3122Exim version 4.44
3123-----------------
3124
3125 1. Change 4.43/35 introduced a bug that caused file counts to be
3126 incorrectly computed when quota_filecount was set in an appendfile
3127 transport
3128
3129 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3130 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3131 place.
3132
3133 3. Give more explanation in the error message when the command for a transport
3134 filter fails to execute.
3135
3136 4. There are several places where Exim runs a non-Exim command in a
3137 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3138 was being done only for the command run by the queryprogram router. It is
3139 now done for all such subprocesses. The other cases are: ${run, transport
3140 filters, and the commands run by the lmtp and pipe transports.
3141
3142 5. Some older OS have a limit of 256 on the maximum number of file
3143 descriptors. Exim was using setrlimit() to set 1000 as a large value
3144 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3145 systems. I've change it so that if it can't get 1000, it tries for 256.
3146
3147 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3148 was an oversight, and furthermore, ever since the addition of extra
3149 controls (e.g. 4.43/32), the checks on when to allow different forms of
3150 "control" were broken. There should now be diagnostics for all cases when a
3151 control that does not make sense is encountered.
3152
3153 7. $recipients is now available in the predata ACL (oversight).
3154
3155 8. Tidy the search cache before the fork to do a delivery from a message
3156 received from the command line. Otherwise the child will trigger a lookup
3157 failure and thereby defer the delivery if it tries to use (for example) a
3158 cached ldap connection that the parent has called unbind on.
3159
3160 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3161 of $address_data from the recipient verification was clobbered by the
3162 sender verification.
3163
316410. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3165 was its contents. (It was OK if the option was not defined at all.)
3166
316711. A "Completed" log line is now written for messages that are removed from
3168 the spool by the -Mrm option.
3169
317012. $host_address is now set to the target address during the checking of
3171 ignore_target_hosts.
3172
317313. When checking ignore_target_hosts for an ipliteral router, no host name was
3174 being passed; this would have caused $sender_host_name to have been used if
3175 matching the list had actually called for a host name (not very likely,
3176 since this list is usually IP addresses). A host name is now passed as
3177 "[x.x.x.x]".
3178
317914. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3180 code that specifies a non-restarting handler (typically sigaction() in
3181 modern systems) in an attempt to fix a rare and obscure crash bug.
3182
318315. Narrowed the window for a race in the daemon that could cause it to ignore
3184 SIGCHLD signals. This is not a major problem, because they are used only to
3185 wake it up if nothing else does.
3186
318716. A malformed maildirsize file could cause Exim to calculate negative values
3188 for the mailbox size or file count. Odd effects could occur as a result.
3189 The maildirsize information is now recalculated if the size or filecount
3190 end up negative.
3191
319217. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3193 support for a long time. Removed HAVE_SYS_VFS_H.
3194
ea3a6f44 319518. Updated exipick to current release from John Jetmore.

319719. Allow an empty sender to be matched against a lookup in an address list.
3198 Previously the only cases considered were a regular expression, or an
3199 empty pattern.
3200
320120. Exim went into a mad DNS lookup loop when doing a callout where the
3202 host was specified on the transport, if the DNS lookup yielded more than
3203 one IP address.

320521. The RFC2047 encoding function was originally intended for short strings
3206 such as real names; it was not keeping to the 75-character limit for
3207 encoded words that the RFC imposes. It now respects the limit, and
3208 generates multiple encoded words if necessary. To be on the safe side, I
3209 have increased the buffer size for the ${rfc2047: expansion operator from
3210 1024 to 2048 bytes.

321222. Failure to deliver a bounce message always caused it to be frozen, even if
3213 there was an errors_to setting on the router. The errors_to setting is now
3214 respected.

3215
321623. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3217 canonical form (fully expanded) before being placed in
3218 $sender_host_address.
3219
322024. Updated eximstats to version 1.33
3221
ea3a6f44

322225. Include certificate and key file names in error message when GnuTLS fails
3223 to set them up, because the GnuTLS error message doesn't include the name
3224 of the failing file when there is a problem reading it.
bbe902f0

3225
322626. Expand error message when OpenSSL has problems setting up cert/key files.

322927. Reset the locale to "C" after calling embedded Perl, in case it was changed
3230 (this can affect the format of dates).
bbe902f0 3231

323228. exim_tidydb, when checking for the continued existence of a message for
3233 which it has found a message-specific retry record, was not finding
3234 messages that were in split spool directories. Consequently, it was
3235 deleting retry records that should have stayed in existence.

323729. eximstats updated to version 1.35
3238 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3239 1.35 - bugfix such that pie charts by volume are generated correctly

324130. The SPA authentication driver was not abandoning authentication and moving
3242 on to the next authenticator when an expansion was forced to fail,
3243 contradicting the general specification for all authenticators. Instead it
3244 was generating a temporary error. It now behaves as specified.

324631. The default ordering of permitted cipher suites for GnuTLS was pessimal
3247 (the order specifies the preference for clients). The order is now AES256,
3248 AES128, 3DES, ARCFOUR128.

3251 autoreply.

325332. Exim crashed if a remote delivery caused a very long error message to be
3254 recorded - for instance if somebody sent an entire SpamAssassin report back
3255 as a large number of 550 error lines. This bug was coincidentally fixed by
3256 increasing the size of one of Exim's internal buffers (big_buffer) that
3257 happened as part of the Exiscan merge. However, to be on the safe side, I
3258 have made the code more robust (and fixed the comments that describe what
3259 is going on).
bbe902f0 3260

326133. Some experimental protocols are using DNS PTR records for new purposes. The
3262 keys for these records are domain names, not reversed IP addresses. The
3263 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3264 leaves it alone. Component reversal etc. now happens only for IP addresses.

326734. The host_aton() function is supposed to be passed a string that is known
3268 to be a valid IP address. However, in the case of IPv6 addresses, it was
3269 not checking this. This is a hostage to fortune. Exim now panics and dies
3270 if the condition is not met. A case was found where this could be provoked
3271 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3272 components; fortuitously, this particular loophole had already been fixed
3273 by change 4.50/55 or 4.44/33 above.
3274
3275 If there are any other similar loopholes, the new check in host_aton()
3276 itself should stop them being exploited. The report I received stated that
3277 data on the command line could provoke the exploit when Exim was running as
3278 exim, but did not say which command line option was involved. All I could
3279 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3280 running as the user.

328335. There was a buffer overflow vulnerability in the SPA authentication code
3284 (which came originally from the Samba project). I have added a test to the
3285 spa_base64_to_bits() function which I hope fixes it.

328836. The daemon start-up calls getloadavg() while still root for those OS that
3289 need the first call to be done as root, but it missed one case: when
3290 deliver_queue_load_max is set with deliver_drop_privilege. This is
3291 necessary for the benefit of the queue runner, because there is no re-exec
3292 when deliver_drop_privilege is set.
bbe902f0 3293
ea3a6f44

329437. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3295 was in use, was not putting the data itself into the right store pool;
3296 consequently, it could be overwritten for a subsequent message in the same
3297 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3298 the caching.)

330038. Sometimes the final signoff response after QUIT could fail to get
3301 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3302 < 0 before doing a fflush(). This bug looks as though it goes back to the
3303 introduction of TLS in release 3.20, but "sometimes" must have been rare
3304 because the tests only now provoked it.

3307Exim version 4.43
3308-----------------
3309
3310 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3311 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3312 Now it returns an integer. A number of calls were still expecting a T/F
3313 return. Fortuitously, in all cases, the tests worked in OK situations,
3314 which is the norm. However, things would have gone wrong on any write
3315 failures on the smtp file descriptor. This function is used when sending
3316 messages over SMTP and also when doing verify callouts.
3317
3318 2. When Exim is called to do synchronous delivery of a locally submitted
3319 message (the -odf or -odi options), it no longer closes stderr before doing
3320 the delivery.
3321
3322 3. Implemented the mua_wrapper option.
3323
3324 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3325
3326 5. Implemented the functions header_remove(), header_testname(),
3327 header_add_at_position(), and receive_remove_recipient(), and exported them
3328 to local_scan().
3329
3330 6. If an ACL "warn" statement specified the addition of headers, Exim already
3331 inserted X-ACL-Warn: at the start if there was no header name. However, it
3332 was not making this test for the second and subsequent header lines if
3333 there were newlines in the string. This meant that an invalid header could
3334 be inserted if Exim was badly configured.
3335
3336 7. Allow an ACL "warn" statement to add header lines at the start or after all
3337 the Received: headers, as well as at the end.
3338
3339 8. Added the rcpt_4xx retry error code.
3340
3341 9. Added postmaster_mailfrom=xxx to callout verification option.
3342
334310. Added mailfrom=xxxx to the callout verification option, for verify=
3344 header_sender only.
3345
334611. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3347 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3348
334912. Inserted some casts to stop certain compilers warning when using pointer
3350 differences as field lengths or precisions in printf-type calls (mostly
3351 affecting debugging statements).
3352
335313. Added optional readline() support for -be (dynamically loaded).
3354
335514. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3356 same clock tick as a message's arrival, so that its received time was the
3357 same as the "first fail" time on the retry record, and that message
3358 remained on the queue past the ultimate address timeout, every queue runner
3359 would try a delivery (because it was past the ultimate address timeout) but
3360 after another failure, the ultimate address timeout, which should have then
3361 bounced the address, did not kick in. This was a "< instead of <=" error;
3362 in most cases the first failure would have been in the next clock tick
3363 after the received time, and all would be well.
3364
336515. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3366 being recognized when the domain list was tested by the match_domain
3367 condition in an expansion string.
3368
336916. Added the ${str2b64: operator.
3370
337117. Exim was always calling setrlimit() to set a large limit for the number of
3372 processes, without checking whether the existing limit was already
3373 adequate. (It did check for the limit on file descriptors.) Furthermore,
3374 errors from getrlimit() and setrlimit() were being ignored. Now they are
3375 logged to the main and panic logs, but Exim does carry on, to try to do its
3376 job under whatever limits there are.
3377
337818. Imported PCRE 5.0.
3379
338019. Trivial typo in log message " temporarily refused connection" (the leading
3381 space).
3382
338320. If the log selector return_path_on_delivery was set and an address was
3384 redirected to /dev/null, the delivery process crashed because it assumed
3385 that a return path would always be set for a "successful" delivery. In this
3386 case, the whole delivery is bypassed as an optimization, and therefore no
3387 return path is set.
3388
338921. Internal re-arrangement: the function for sending a challenge and reading
3390 a response while authentication was assuming a zero-terminated challenge
3391 string. It's now changed to take a pointer and a length, to allow for
3392 binary data in such strings.
3393
339422. Added the cyrus_sasl authenticator (code supplied by MBM).
3395
339623. Exim was not respecting finduser_retries when seeking the login of the
3397 uid under which it was called; it was always trying 10 times. (The default
3398 setting of finduser_retries is zero.) Also, it was sleeping after the final
3399 failure, which is pointless.
3400
340124. Implemented tls_on_connect_ports.
3402
340325. Implemented acl_smtp_predata.
3404
340526. If the domain in control=submission is set empty, Exim assumes that the
3406 authenticated id is a complete email address when it generates From: or
3407 Sender: header lines.
3408
340927. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3410 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3411 chown and chgrp in /bin and hostname in /usr/bin.
3412
341328. Exim was keeping the "process log" file open after each use, just as it
3414 does for the main log. This opens the possibility of it remaining open for
3415 long periods when the USR1 signal hits a daemon. Occasional processlog
3416 errors were reported, that could have been caused by this. Anyway, it seems
3417 much more sensible not to leave this file open at all, so that is what now
3418 happens.
3419
342029. The long-running daemon process does not normally write to the log once it
3421 has entered its main loop, and it closes the log before doing so. This is
3422 so that log files can straightforwardly be renamed and moved. However,
