462
463 Note to Michael Haardt: I had to rename some vars in sieve.c. They
464 were called 'true' and it seems that C99 defines that as a reserved
465 keyword to be used with 'bool' variable types. That means you could
466 not include C99-style headers which use bools without triggering
467 build errors in sieve.c.

485PH/01 Another patch from the Sieve maintainer.
486
6a3bceb1
PH
487PH/02 When an IPv6 address is converted to a string for single-key lookup
488 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
489 dots are used instead of colons so that keys in lsearch files need not
490 contain colons. This was done some time before quoting was made available
491 in lsearch files. However, iplsearch files do require colons in IPv6 keys
492 (notated using the quote facility) so as to distinguish them from IPv4
493 keys. This meant that lookups for IP addresses in host lists did not work
494 for iplsearch lookups.
495
496 This has been fixed by arranging for IPv6 addresses to be expressed with
497 colons if the lookup type is iplsearch. This is not incompatible, because
498 previously such lookups could never work.
499
500 The situation is now rather anomolous, since one *can* have colons in
501 ordinary lsearch keys. However, making the change in all cases is
502 incompatible and would probably break a number of configurations.

MH
507MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
508 conversion specification without a maximum field width, thereby enabling
509 a rogue spamd server to cause a buffer overflow. While nobody in their
510 right mind would setup Exim to query an untrusted spamd server, an
511 attacker that gains access to a server running spamd could potentially
512 exploit this vulnerability to run arbitrary code as the Exim user.

MH
517MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
518 a directory entry by the name of the lookup key. Previously, if a
519 symlink pointed to a non-existing file or a file in a directory that
520 Exim lacked permissions to read, a lookup for a key matching that
521 symlink would fail. Now it is enough that a matching directory entry
522 exists, symlink or not. (Bugzilla 503.)

595PH/02 In an ACL statement such as
596
597 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
598
599 if a client was not listed at all, or was listed with a value other than
600 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
601 the condition was not true (as it should be), so access was not denied.
602 The bug was that the ! inversion was incorrectly passed on to the second
603 item. This has been fixed.

627PH/07 There was a bug in the dovecot authenticator such that the value of

636PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
637 run for batched SMTP input. It is now run at the start of every message
638 in the batch. While fixing this I discovered that the process information
639 (output by running exiwhat) was not always getting set for -bs and -bS
640 input. This is fixed, and it now also says "batched" for BSMTP.

700PH/28 The $smtp_command and $smtp_command_argument variables were not correct

704
a14e5636
PH
705PH/29 SMTP synchronization checks are implemented when a command is read -
706 there is a check that no more input is waiting when there shouldn't be
707 any. However, for some commands, a delay in an ACL can mean that it is
708 some time before the response is written. In this time, more input might
709 arrive, invalidly. So now there are extra checks after an ACL has run for
710 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
711 pipelining has not been advertised.

726 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
727 was a macro that became an assignment, so it seemed to work. This has
728 changed to a proper function call with a void return, hence the compile
729 error. Exim's code has been fixed.

PH
757PH/40 When Exim receives a message, it writes the login name, uid, and gid of
758 whoever called Exim into the -H file. In the case of the daemon it was
759 behaving confusingly. When first started, it used values for whoever
760 started the daemon, but after a SIGHUP it used the Exim user (because it
761 calls itself on a restart). I have changed the code so that it now always
762 uses the Exim user.

PH
764PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

766 sender address), and a DATA command is nevertheless sent (as can happen
767 with PIPELINING or a stupid MUA), the error message that was given to the
768 RCPT commands is included in the rejection of the DATA command. This is

58eb016e 784PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
785 the response to the final '.' that terminates a message, but only in the
786 case where the client has not sent further data following the '.'
787 (unfortunately, this is allowed). However, in many cases there won't be
788 any further data because there won't be any more messages to send. A call
789 to select() can be used: if it shows that the input is "ready", there is
790 either input waiting, or the socket has been closed. An attempt to read
791 the next input character can distinguish the two cases. Previously, Exim
58eb016e 792 would have sent an OK response which the client would never have see.

800Exim version 4.66
801-----------------
802
803PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
804 fixed by 4.65/MH/01 (is this a record?) are fixed:
805
806 (i) An empty string was always treated as zero by the numeric comparison
807 operators. This behaviour has been restored.
808
809 (ii) It is documented that the numeric comparison operators always treat
810 their arguments as decimal numbers. This was broken in that numbers
811 starting with 0 were being interpreted as octal.
812
813 While fixing these problems I realized that there was another issue that
814 hadn't been noticed. Values of message_size_limit (both the global option
815 and the transport option) were treated as octal if they started with 0.
816 The documentation was vague. These values are now always treated as
817 decimal, and I will make that clear in the documentation.

PH
831PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
832 child addresses, Exim now panics and dies. Previously, because the count
833 is held in a short int, deliveries were likely to be lost. As such a
834 large number of recipients for a single message is ridiculous
835 (performance will be very, very poor), I have chosen to impose a limit
836 rather than extend the field.

TK
842TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
843 leftover -K file (the existence of which was triggered by #402).
844 While we were at it, introduced process PID as part of the -K
845 filename. This should rule out race conditions when creating
846 these files.
847
848TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
849 processing considerably. Previous code took too long for large mails,
850 triggering a timeout which in turn triggers #401.
851
852TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
853 in the DK code in transports.c. sendfile() is not really portable,
854 hence the _LINUX specificness.

856TF/01 In the add_headers option to the mail command in an Exim filter,
857 there was a bug that Exim would claim a syntax error in any
858 header after the first one which had an odd number of characters
859 in the field name.

PH
861PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
862 callout verification, Exim cached a "reject" for the entire domain. This
863 is correct for most verifications, but it is not correct for a recipient
864 verification with use_sender or use_postmaster set, because in that case
865 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
866 case of MAIL FROM:<> rejection from other early rejections (e.g.
867 rejection of HELO). When verifying a recipient using a non-null MAIL
868 address, the cache is ignored if it shows MAIL FROM:<> rejection.
869 Whatever the result of the callout, the value of the domain cache is
870 left unchanged (for any other kind of callout, getting as far as trying
871 RCPT means that the domain itself is ok).

905PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
906 hostname. This is wrong, because it relates to the incoming message (and
907 probably the interface on which it is arriving) and not to the outgoing
908 callout (which could be using a different interface). This has been
909 changed to use the value of the helo_data option from the smtp transport
910 instead - this is what is used when a message is actually being sent. If
911 there is no remote transport (possible with a router that sets up host
912 addresses), $smtp_active_hostname is used.
6ea85e9a 913
14aa5a05 914PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 915 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
916 (a) The code assumed that strncpy() returns a negative number on buffer
917 overflow, which isn't the case. Replaced with Exim's string_format()
918 function.
919 (b) There were several signed/unsigned issues. I just did the minimum
920 hacking in of casts. There is scope for a larger refactoring.
921 (c) The code used strcasecmp() which is not a standard C function.
922 Replaced with Exim's strcmpic() function.
923 (d) The code set only $1; it now sets $auth1 as well.
924 (e) A simple test gave the error "authentication client didn't specify
925 service in request". It would seem that Dovecot has changed its
926 interface. Fortunately there's a specification; I followed it and
927 changed what the client sends and it appears to be working now.

932PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
933 address A is aliased to B and C, where B exists and C does not. Without
934 -v the output is "A verified" because verification stops after a
935 successful redirection if more than one address is generated. However,
936 with -v the child addresses are also verified. Exim was outputting "A
937 failed to verify" and then showing the successful verification for C,
938 with its parentage. It now outputs "B failed to verify", showing B's
939 parentage before showing the successful verification of C.

941PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
942 look up a TXT record in a specific list after matching in a combined
943 list.
944
322050c2
PH
945PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
946 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
947 they consult the DNS. I had assumed they would set it the way they
948 wanted; and indeed my experiments on Linux seem to show that in some
949 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
950 To be on the safe side, however, I have now made the interface to
951 host_find_byname() similar to host_find_bydns(), with an argument
952 containing the DNS resolver options. The host_find_byname() function now
953 sets these options at its start, just as host_find_bydns() does. The smtp
954 transport options dns_qualify_single and dns_search_parents are passed to
955 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
956 of host_find_byname() use the default settings of RES_DEFNAMES
957 (qualify_single) but not RES_DNSRCH (search_parents).
958

PH
959PH/17 Applied (a modified version of) Nico Erfurth's patch to make
960 spool_read_header() do less string testing, by means of a preliminary
961 switch on the second character of optional "-foo" lines. (This is
962 overdue, caused by the large number of possibilities that now exist.
963 Originally there were few.) While I was there, I also converted the
964 str(n)cmp tests so they don't re-test the leading "-" and the first
965 character, in the hope this might squeeze out yet more improvement.
966

PH
967PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
968 flag allowing group syntax was set by the header_syntax check but not
969 turned off, possible causing trouble later; (2) The flag was not being
970 set at all for the header_verify test, causing "group"-style headers to
971 be rejected. I have now set it in this case, and also caused header_
972 verify to ignore an empty address taken from a group. While doing this, I
973 came across some other cases where the code for allowing group syntax
974 while scanning a header line wasn't quite right (mostly, not resetting
975 the flag correctly in the right place). These bugs could have caused
976 trouble for malformed header lines. I hope it is now all correct.
977
602e59e5
PH
978PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
979 with the "reply" argument non-NULL. The code, however (which originally
980 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
981 but it didn't always do it. This confused somebody who was copying the
982 code for some other use. I have removed all the tests.

411ef850
PH
984PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
985 feature that was used to support insecure browsers during the U.S. crypto
986 embargo. It requires special client support, and Exim is probably the
987 only MTA that supported it -- and would never use it because real RSA is
988 always available. This code has been removed, because it had the bad
989 effect of slowing Exim down by computing (never used) parameters for the
990 RSA_EXPORT functionality.
991
7befa435
PH
992PH/21 On the advice of Timo Sirainen, added a check to the dovecot
993 authenticator to fail if there's a tab character in the incoming data
994 (there should never be unless someone is messing about, as it's supposed
995 to be base64-encoded). Also added, on Timo's advice, the "secured" option
996 if the connection is using TLS or if the remote IP is the same as the
997 local IP, and the "valid-client-cert option" if a client certificate has
998 been verified.

PH
1029
1030PH/30 Exim was sometimes attempting to deliver messages that had suffered
1031 address errors (4xx response to RCPT) over the same connection as other
1032 messages routed to the same hosts. Such deliveries are always "forced",
1033 so retry times are not inspected. This resulted in far too many retries
1034 for the affected addresses. The effect occurred only when there were more
1035 hosts than the hosts_max_try setting in the smtp transport when it had
1036 the 4xx errors. Those hosts that it had tried were not added to the list
1037 of hosts for which the message was waiting, so if all were tried, there
1038 was no problem. Two fixes have been applied:
1039
1040 (i) If there are any address or message errors in an SMTP delivery, none
1041 of the hosts (tried or untried) are now added to the list of hosts
1042 for which the message is waiting, so the message should not be a
1043 candidate for sending over the same connection that was used for a
1044 successful delivery of some other message. This seems entirely
1045 reasonable: after all the message is NOT "waiting for some host".
1046 This is so "obvious" that I'm not sure why it wasn't done
1047 previously. Hope I haven't missed anything, but it can't do any
1048 harm, as the worst effect is to miss an optimization.
1049
1050 (ii) If, despite (i), such a delivery is accidentally attempted, the
1051 routing retry time is respected, so at least it doesn't keep
1052 hammering the server.

PH
1067PH/35 The error "getsockname() failed: connection reset by peer" was being
1068 written to the panic log as well as the main log, but it isn't really
1069 panic-worthy as it just means the connection died rather early on. I have
1070 removed the panic log writing for the ECONNRESET error when getsockname()
1071 fails.
1072
48c7f9e2
PH
1073PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1074 runs only) independently of the message's sender address. This meant
1075 that, if the 4xx error was in fact related to the sender, a different
1076 message to the same recipient with a different sender could confuse
1077 things. In particualar, this can happen when sending to a greylisting
1078 server, but other circumstances could also provoke similar problems.
1079 I have changed the default so that the retry time for these errors is now
1080 based a combination of the sender and recipient addresses. This change
1081 can be overridden by setting address_retry_include_sender=false in the
1082 smtp transport.

1350PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1352 Unfortunately, if there is a major crisis, such as a disk failure,
1353 tcp-wrappers gives "deny", whereas what one would like would be some
1354 kind of temporary error. A kludge has been added to help with this.
1355 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1356 554 error is used if errno is still zero or contains ENOENT (which occurs
1357 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1358 451 error is used.

1394PH/01 The code for finding all the local interface addresses on a FreeBSD
1395 system running IPv6 was broken. This may well have applied to all BSD
1396 systems, as well as to others that have similar system calls. The broken
1397 code found IPv4 interfaces correctly, but gave incorrect values for the
1398 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1399 that it would not match correctly against @[] and not recognize the IPv6
1400 addresses as local.

1443 autoreply, Exim could try to deliver to a non-existent relative file
1444 name, causing unrelated and misleading errors. What now happens is that

1466 (a) Failures to set uid/gid, the current directory, or a process leader
1467 in a subprocess such as that created by queryprogram now generate
1468 suitable debugging ouput when -d is set.

1472 the subprocess without attempting to change uid/gid.

1478 additional section of a DNS packet that returns MX or SRV records.
1479 Instead, it always explicitly searches for A/AAAA records. This avoids
1480 major problems that occur when a DNS server includes only records of one
1481 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1482 fixed another bug: if SRV records were looked up and the corresponding
1483 address records were *not* found in the additional section, the port
1484 values from the SRV records were lost.

1486PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
1494PH/19 When calculating a retry time, Exim used to measure the "time since
1495 failure" by looking at the "first failed" field in the retry record. Now
1496 it does not use this if it is later than than the arrival time of the
1497 message. Instead it uses the arrival time. This makes for better
1498 behaviour in cases where some deliveries succeed, thus re-setting the
1499 "first failed" field. An example is a quota failure for a huge message
1500 when small messages continue to be delivered. Without this change, the
1501 "time since failure" will always be short, possible causing more frequent
1502 delivery attempts for the huge message than are intended.

PH
1599PH/42 The content-scanning code uses fopen() to create files in which to put
1600 message data. Previously it was not paying any attention to the mode of
1601 the files. Exim runs with umask(0) because the rest of the code creates
1602 files with open(), and sets the required mode explicitly. Thus, these
1603 files were ending up world-writeable. This was not a big issue, because,
1604 being within the spool directory, they were not world-accessible. I have
1605 created a function called modefopen, which takes an additional mode
1606 argument. It sets umask(777), creates the file, chmods it to the required
1607 mode, then resets the umask. All the relevant calls to fopen() in the
1608 content scanning code have been changed to use this function.

1616PH/45 When the plaintext authenticator is running as a client, the server's
1617 challenges are checked to ensure they are valid base64 strings. By
1618 default, the authentication attempt is cancelled if an invalid string is
1619 received. Setting client_ignore_invalid_base64 true ignores these errors.
1620 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1621 they are received. Thus, the responses can be made to depend on the
1622 challenges. If an invalid string is ignored, an empty string is placed in
1623 the variable.

PH
1643PH/52 Two bugs concerned with error handling when the smtp transport is
1644 used in LMTP mode:
1645
1646 (i) Exim was not creating retry information for temporary errors given
1647 for individual recipients after the DATA command when the smtp transport
1648 was used in LMTP mode. This meant that they could be retried too
1649 frequently, and not timed out correctly.
1650
1651 (ii) Exim was setting the flag that allows error details to be returned
1652 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1653 recipients that were returned after the DATA command.
1654
1655PH/53 This is related to PH/52, but is more general: for any failing address,
1656 when detailed error information was permitted to be returned to the
1657 sender, but the error was temporary, then after the final timeout, only
1658 "retry timeout exceeded" was returned. Now it returns the full error as
1659 well as "retry timeout exceeded".

PH
1729PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1730 function verify_get_ident() calls ip_connect() to connect a socket, but
1731 if the "connect()" function timed out, ip_connect() used to close the
1732 socket. However, verify_get_ident() also closes the socket later, and in
1733 between Exim writes to the log, which may get opened at this point. When
1734 the socket was closed in ip_connect(), the log could get the same file
1735 descriptor number as the socket. This naturally causes chaos. The fix is
1736 not to close the socket in ip_connect(); the socket should be closed by
1737 the function that creates it. There was only one place in the code where
1738 this was missing, in the iplookup router, which I don't think anybody now
1739 uses, but I've fixed it anyway.

1762
1763 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1764 string.
1765
1766 (3) Reset the variables that are obtained from the first argument of
1767 ${prvscheck and used in the second argument before leaving the code,
1768 because their memory is reclaimed, so using them afterwards may do
1769 silly things.
1770
1771 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1772 one (it's much easier than Tom thought :-).

1790 may be more than one such address. If so, they are comma-separated, like

1795PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1796 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1797 not being looked up in the rDNS to get a host name, Exim was showing the
1798 IP address twice in Received: lines, even though the IP addresses were
1799 identical. For example:
1800
1801 Received: from [1.2.3.4] (helo=[1.2.3.4])
1802
1803 However, if the real host name was known, it was omitting the HELO data
1804 if it matched the actual IP address. This has been tidied up so that it
1805 doesn't show the same IP address twice.

1831PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

1833
1834 Auto-submitted: auto-generated
1835
1836 in the messages that it generates (bounce messages and others, such as
1837 warnings). In the case of bounce messages for non-SMTP mesages, there was
1838 also a typo: it was using "Auto_submitted" (underscore instead of
1839 hyphen). Since every message generated by Exim is necessarily in response
1840 to another message, thes have all been changed to:
1841
1842 Auto-Submitted: auto-replied
1843
1844 in accordance with these statements in the RFC:
1845
1846 The auto-replied keyword:
1847
1848 - SHOULD be used on messages sent in direct response to another
1849 message by an automatic process,
1850
1851 - MUST NOT be used on manually-generated messages,
1852
1853 - MAY be used on Delivery Status Notifications (DSNs) and Message
1854 Disposition Notifications (MDNs),

1894PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

1896 the IP address, check_host() was doing a simple string comparison with
1897 addresses acquired from the DNS when checking that the found name did
1898 have the original IP as one of its addresses. Since any found IPv6
1899 addresses are likely to be in abbreviated form, the comparison could
1900 fail. Luckily, there already exists a function for doing the comparison
1901 by converting both addresses to binary, so now that is used instead of
1902 the text comparison.

2200 with the definition in sysexits.h (which is #included earlier).
2201 Fortunately, Exim does not actually use EX_OK. The code used to try to
2202 preserve the sysexits.h value, by assumimg that macro definitions were
2203 scanned for macro replacements. I have been disabused of this notion,

2211 doesn't have to be particularly precise.

2385 message was deferred as in a normal delivery, and thus remained on the
2386 spool, instead of being failed because of the mua_wrapper setting. This
2387 is now fixed, and I tidied up some of the mua_wrapper messages at the
2388 same time.

2419
2420PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2421 that changes the way the GnuTLS parameters are stored in the cache file.
2422 The new format can be generated externally. For backward compatibility,
2423 if the data in the cache doesn't make sense, Exim assumes it has read an
2424 old-format file, and it generates new data and writes a new file. This
2425 means that you can't go back to an older release without removing the
2426 file.
2427
2428PH/03 A redirect router that has both "unseen" and "one_time" set does not
2429 work if there are any delivery delays because "one_time" forces the
2430 parent to be marked "delivered", so its unseen clone is never tried
2431 again. For this reason, Exim now forbids the simultaneous setting of
2432 these two options.
2433
2434PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2435 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2436 entry if you want to know the details. The fix, however, neglected to
2437 consider the case when local delivery batching is involved. The test for
2438 "previously delivered" was not happening when checking to see if an
2439 address could be batched with a previous (undelivered) one; under
2440 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2441 address.

2443PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2446PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2447 header_syntax) but Exim was just ignoring anything given after a slash.
2448 In particular, this caused confusion with an attempt to use "verify =
2449 reverse_host_lookup/defer_ok". An error is now given when options are
2450 supplied for verify items that do not have them. (Maybe reverse_host_
2451 lookup should have a defer_ok option, but that's a different point.)
2452
2453PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2505 ownership right at creation (otherwise, other Exim processes might see
2506 the file with the wrong ownership). There was no test for failure of this
2507 fork() call, which would lead to the process getting stuck as it waited
2508 for a non-existent subprocess. Forks do occasionally fail when resources
2509 run out. I reviewed all the other calls to fork(); they all seem to check

2515 the result was a log entry for a synchronization error with an empty
2516 string after "input=" when read() returned zero. If read() returned -1

PH
2529PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2530 hadn't been configured. The fix is from Juergen Kreileder, who
2531 understands it better than I do:
2532
2533 "Here's what I see happening with three configured cyrus_sasl
2534 authenticators configured (plain, login, cram-md5):
2535
2536 On startup auth_cyrus_sasl_init() gets called for each of these.
2537 This means three calls to sasl_listmech() without a specified mech_list.
2538 => SASL tests which mechs of all available mechs actually work
2539 => three warnings about OTP not working
2540 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2541
2542 With the patch, sasl_listmech() also gets called three times. But now
2543 SASL's mech_list option is set to the server_mech specified in the the
2544 authenticator. Or in other words, the answer from sasl_listmech()
2545 gets limited to just the mech you're testing for (which is different
2546 for each call.)
2547 => the return list contains just 'plain' or 'login', 'cram-md5' or
2548 nothing depending on the value of ob->server_mech.
2549
2550 I've just tested the patch: Authentication still works fine,

PH
2616PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2617 the grounds that routing the same address twice would always produce the
2618 same answer. This might have been true once, but it is certainly no
2619 longer true now. Routing a child address may depend on the previous
2620 routing that produced that child. Some complicated redirection strategies
2621 went wrong when messages had multiple recipients, and made Exim's
2622 behaviour dependent on the order in which the addresses were given.
2623
2624 I have moved the duplicate checking until after the routing is complete.
2625 Exim scans the addresses that are assigned to local and remote
2626 transports, and removes any duplicates. This means that more work will be
2627 done, as duplicates will always all be routed, but duplicates are
2628 presumably rare, so I don't expect this is of any significance.
2629
2630 For deliveries to pipes, files, and autoreplies, the duplicate checking
2631 still happens during the routing process, since they are not going to be
2632 routed further.

2676 successful delivery. Such timeouts include transport filter timeouts. For
2677 consistency with the overall process timeout, these timeouts are now
2678 treated as errors, giving rise to delivery failures by default. However,
2679 there is now a new Boolean option for the pipe transport called
2680 timeout_defer, which, if set TRUE, converts the failures into defers for
2681 both kinds of timeout. A transport filter timeout is now identified in

2691A note about Exim versions 4.44 and 4.50
2692----------------------------------------
2693
2694Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2695changes of various kinds. As a consequence, a big documentation update was
2696needed. This delayed the release for rather longer than seemed good, especially
2697in the light of a couple of (minor) security issues. Therefore, the changes
2698that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2699release. So 4.44 and 4.50 are in effect two different branches that both start
2700from 4.43.
2701
2702I have left the 4.50 change log unchanged; it contains all the changes since
27034.43. The change log for 4.44 is below; many of its items are identical to
2704those for 4.50. This seems to be the most sensible way to preserve the
2705historical information.

2727 filters, and the commands run by the lmtp and pipe transports.

2734 systems. I've change it so that if it can't get 1000, it tries for 256.

278423. When checking ignore_target_hosts for an ipliteral router, no host name was
2785 being passed; this would have caused $sender_host_name to have been used if
2786 matching the list had actually called for a host name (not very likely,
2787 since this list is usually IP addresses). A host name is now passed as
2788 "[x.x.x.x]".
2789
7d468ab8
PH
279024. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2791 code that specifies a non-restarting handler (typically sigaction() in
2792 modern systems) in an attempt to fix a rare and obscure crash bug.
2793
279425. Narrowed the window for a race in the daemon that could cause it to ignore
2795 SIGCHLD signals. This is not a major problem, because they are used only to
2796 wake it up if nothing else does.
2797
62c0818f
PH
279826. A malformed maildirsize file could cause Exim to calculate negative values
2799 for the mailbox size or file count. Odd effects could occur as a result.
2800 The maildirsize information is now recalculated if the size or filecount
2801 end up negative.
2802
26034054
PH
280327. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2804 support for a long time. Removed HAVE_SYS_VFS_H.
2805
af66f652
PH
280628. Installed the latest version of exipick from John Jetmore.
2807
90af77f4
PH
280829. In an address list, if the pattern was not a regular expression, an empty
2809 subject address (from a bounce message) matched only if the pattern was an
2810 empty string. Non-empty patterns were not even tested. This was the wrong
2811 because it is perfectly reasonable to use an empty address as part of a
2812 database query. An empty address is now tested by patterns that are
2813 lookups. However, all the other forms of pattern expect the subject to
2814 contain a local part and a domain, and therefore, for them, an empty
2815 address still always fails if the pattern is not itself empty.
2816
d8ef3577
PH
281730. Exim went into a mad DNS loop when attempting to do a callout where the
2818 host was specified on an smtp transport, and looking it up yielded more
2819 than one IP address.
2820
5cb8cbc6
PH
282131. Re-factored the code for checking spool and log partition space into a
2822 function that finds that data and another that does the check. The former
2823 is then used to implement four new variables: $spool_space, $log_space,
2824 $spool_inodes, and $log_inodes.
2825
14702f5b
PH
282632. The RFC2047 encoding function was originally intended for short strings
2827 such as real names; it was not keeping to the 75-character limit for
2828 encoded words that the RFC imposes. It now respects the limit, and
2829 generates multiple encoded words if necessary. To be on the safe side, I
2830 have increased the buffer size for the ${rfc2047: expansion operator from
2831 1024 to 2048 bytes.
2832
063b1e99
PH
283333. It is now permitted to omit both strings after an "if" condition; if the
2834 condition is true, the result is "true". As before, when the second string
2835 is omitted, a false condition yields an empty string. This makes it less
2836 cumbersome to write custom ACL and router conditions.
2837
652e1b65
PH
283834. Failure to deliver a bounce message always caused it to be frozen, even if
2839 there was an errors_to setting on the router. The errors_to setting is now
2840 respected.
2841
6f0c9a4f
PH
284235. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2843 canonical form (fully expanded) before being placed in
2844 $sender_host_address.
2845
33397d19
PH
284636. The table in the code that translates DNS record types into text (T_A to
2847 "A" for instance) was missing entries for NS and CNAME. It is just possible
2848 that this could have caused confusion if both these types were looked up
2849 for the same domain, because the text type is used as part of Exim's
2850 per-process caching. But the chance of anyone hitting this buglet seems
2851 very small.
2852
7bb56e1f
PH
285337. The dnsdb lookup has been extended in a number of ways.
2854
2855 (1) There is a new type, "zns", which walks up the domain tree until it
2856 finds some nameserver records. It should be used with care.
2857
ea3bc19b
PH
2858 (2) There is a new type, "mxh", which is like "mx" except that it returns
2859 just the host names, not the priorities.
2860
2861 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2862 looked up. The behaviour when one of the lookups defers can be
2863 controlled by a keyword.
7bb56e1f 2864
ea3bc19b 2865 (4) It is now possible to specify the separator character for use when
7bb56e1f 2866 multiple records are returned.
33397d19 2867
0bcb2a0e
PH
286838. The dnslists ACL condition has been extended: it is now possible to supply
2869 a list of IP addresses and/or domains to be looked up in a particular DNS
2870 domain.
2871
2ac0e484
PH
287239. Added log_selector=+queue_time_overall.
2873
4e1fde53
PH
287440. When running the queue in the test harness, wait just a tad after forking a
2875 delivery process, to get repeatability of debugging output.
2876
de365ded
PH
287741. Include certificate and key file names in error message when GnuTLS fails
2878 to set them up, because the GnuTLS error message doesn't include the name
2879 of the failing file when there is a problem reading it.
2880
f05da2e8
PH
288142. Allow both -bf and -bF in the same test run.
2882
d6453af2
PH
288343. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
2884
f7b63901
PH
288544. The "Exiscan patch" is now merged into the mainline Exim source.
2886
288745. Sometimes the final signoff response after QUIT could fail to get
2888 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2889 < 0 before doing a fflush(). This bug looks as though it goes back to the
2890 introduction of TLS in release 3.20, but "sometimes" must have been rare
2891 because the tests only now provoked it.
2892
a444213a
PH
289346. Reset the locale to "C" after calling embedded Perl, in case it was changed
2894 (this can affect the format of dates).
2895
0ec020ea
PH
289647. exim_tidydb, when checking for the continued existence of a message for
2897 which it has found a message-specific retry record, was not finding
2898 messages that were in split spool directories. Consequently, it was
2899 deleting retry records that should have stayed in existence.
2900
b1206957
PH
290148. Steve fixed some bugs in eximstats.
2902
290349. The SPA authentication driver was not abandoning authentication and moving
2904 on to the next authenticator when an expansion was forced to fail,
2905 contradicting the general specification for all authenticators. Instead it
2906 was generating a temporary error. It now behaves as specified.
2907
26dd5a95
PH
290850. The default ordering of permitted cipher suites for GnuTLS was pessimal
2909 (the order specifies the preference for clients). The order is now AES256,
2910 AES128, 3DES, ARCFOUR128.
2911
343b2385
PH
291251. Small patch to Sieve code - explicitly set From: when generating an
2913 autoreply.
2914
1c5466b9
PH
291552. Exim crashed if a remote delivery caused a very long error message to be
2916 recorded - for instance if somebody sent an entire SpamAssassin report back
2917 as a large number of 550 error lines. This bug was coincidentally fixed by
2918 increasing the size of one of Exim's internal buffers (big_buffer) that
2919 happened as part of the Exiscan merge. However, to be on the safe side, I
2920 have made the code more robust (and fixed the comments that describe what
2921 is going on).
2922
55ee9ee3
PH
292353. Now that there can be additional text after "Completed" in log lines (if
2924 the queue_time_overall log selector is set), a one-byte patch to exigrep
2925 was needed to allow it to recognize "Completed" as not the last thing in
2926 the line.
2927
d38f8232
PH
292854. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2929 patch that reportedly fixes this has been added. I am not expert enough to
2930 create a test for it. This is what the patch creator wrote:
2931
2932 "I found a little strange behaviour of ldap code when working with
2933 Windows 2003 AD Domain, where users was placed in more than one
2934 Organization Units. When I tried to give exim partial DN, the exit code
2935 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2936 But simultaneously result of request was absolutely normal ldap result,
2937 so I produce this patch..."
2938
3295e65b
PH
2939 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2940 REFERENCE, so I have modified the code to exclude the patch when that macro
2941 is not defined.
2942
7102e136
PH
294355. Some experimental protocols are using DNS PTR records for new purposes. The
2944 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2945 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2946 leaves it alone. Component reversal etc. now happens only for IP addresses.
ea3a6f44 2947 CAN-2005-0021
7102e136 2948
3ca0ba97
PH
294956. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
2950
c2bcbe20
PH
295157. Double the size of the debug message buffer (to 2048) so that more of very
2952 long debug lines gets shown.
2953
18ce445d
PH
295458. The exicyclog utility now does better if the number of log files to keep
2955 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
2956
1f5b4c3d
PH
295759. Two changes related to the smtp_active_hostname option:
2958
2959 (1) $smtp_active_hostname is now available as a variable.
2960 (2) The default for smtp_banner uses $smtp_active_hostname instead
2961 of $primary_hostname.
2962
b975ba52
PH
296360. The host_aton() function is supposed to be passed a string that is known
2964 to be a valid IP address. However, in the case of IPv6 addresses, it was
2965 not checking this. This is a hostage to fortune. Exim now panics and dies
2966 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2967 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2968 components; fortuitously, this particular loophole had already been fixed
2969 by change 4.50/55 above.
2970
2971 If there are any other similar loopholes, the new check in host_aton()
2972 itself should stop them being exploited. The report I received stated that
2973 data on the command line could provoke the exploit when Exim was running as
2974 exim, but did not say which command line option was involved. All I could
2975 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2976 running as the user.
ea3a6f44 2977 CAN-2005-0021
85b87bc2
PH
2978
297961. There was a buffer overflow vulnerability in the SPA authentication code
2980 (which came originally from the Samba project). I have added a test to the
2981 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 2982 CAN-2005-0022
b975ba52 2983
17ffcae7
PH
298462. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
2985 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
2986
d95f9fdb
PH
298763. The daemon start-up calls getloadavg() while still root for those OS that
2988 need the first call to be done as root, but it missed one case: when
2989 deliver_queue_load_max is set with deliver_drop_privilege. This is
2990 necessary for the benefit of the queue runner, because there is no re-exec
2991 when deliver_drop_privilege is set.
2992
86b8287f
PH
299364. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
2994 This has been fixed.
2995
60dc5e56
PH
299665. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2997 was in use, was not putting the data itself into the right store pool;
2998 consequently, it could be overwritten for a subsequent message in the same
2999 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3000 the caching.)
3001
533244af
PH
300266. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3003
a5a28604
PH
300467. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3005 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3006 the function were treating the return as a boolean value, which happened to
3007 work because 0=false and not-0=true, but is not correct code.
3008
7e634d24
PH
300968. The host_aton() function was not handling scoped IPv6 addresses (those
3010 with, for example, "%eth0" on the end) correctly.
3011
3e11c26b
PH
301269. Fixed some compiler warnings in acl.c for the bitmaps specified with
3013 negated items (that is, ~something) in unsigned ints. Some compilers
3014 apparently mutter when there is no cast.
3015
6729cf78
PH
301670. If an address verification called from an ACL failed, and did not produce a
3017 user-specific message (i.e. there was only a "system" message), nothing was
3018 put in $acl_verify_message. In this situation, it now puts the system
3019 message there.
3020
00f00ca5
PH
302171. Change 4.23/11 added synchronization checking at the start of an SMTP
3022 session; change 4.31/43 added the unwanted input to the log line - except
3023 that it did not do this in the start of session case. It now does.
3024
c9bdd01c
PH
302572. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3026 This is wrong and can cause the other end to generate a synchronization
3027 error if it is another Exim or anything else that does the synchronization
3028 check. A QUIT command is no longer sent after a timeout.
3029
d43194df
PH
303073. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3031 during host lookups.
3032
fe5b5d0b
PH
303374. The defer_ok option of callout verification was not working if it was used
3034 when verifying addresses in header lines, that is, for this case:
3035
3036 verify = header_sender/callout=defer_ok
3037
76a2d7ba
PH
303875. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3039 those file descriptors could be used for SMTP connections. If anything
3040 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3041 could be sent to the SMTP client, causing chaos. The daemon now opens
3042 stdin, stdout, and stderr to /dev/null when it puts itself into the
3043 background.
3044
304576. Arrange for output from Perl's "warn" command to be written to Exim's main
3046 log by default. The user can override this with suitable Perl magic.
3047
04f7d5b9
PH
304877. The use of log_message on a "discard" ACL verb, which is supposed to add to
3049 the log message when discard triggers, was not working for the DATA ACL or
3050 for the non-SMTP ACL.
3051
bc60667e
PH
305278. Error message wording change in sieve.c.
3053
bb6e88ff
PH
305479. If smtp_accept_max_per_host was set, the number of connections could be
3055 restricted to fewer than expected, because the daemon was trying to set up
3056 a new connection before checking whether the processes handling previous
3057 connections had finished. The check for completed processes is now done
3058 earlier. On busy systems, this bug wouldn't be noticed because something
3059 else would have woken the daemon, and it would have reaped the completed
3060 process earlier.
3061
1e70f85b
PH
306280. If a message was submitted locally by a user whose login name contained one
3063 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3064 It caused a spool format error. I have fixed the spool reading code. A
3065 related problem was that the "from" clause in the Received: line became
3066 illegal because of the space(s). It is now covered by ${quote_local_part.
3067
306881. Included the latest eximstats from Steve (adds average sizes to HTML Top
3069 tables).
3070
4e01f9d6
PH
307182. Updated OS/Makefile-AIX as per message from Mike Meredith.
3072

PH
307383. Patch from Sieve maintainer to fix unterminated string problem in
3074 "vacation" handling.
3075
6e2b4ccc
PH
307684. Some minor changes to the Linux configuration files to help with other
3077 OS variants using glibc.
3078
8e669ac1
PH
307985. One more patch for Sieve to update vacation handling to latest spec.

3082----------------------------------------------------
3083See the note above about the 4.44 and 4.50 releases.
3084----------------------------------------------------
3085
3086
3087Exim version 4.44
3088-----------------
3089
3090 1. Change 4.43/35 introduced a bug that caused file counts to be
3091 incorrectly computed when quota_filecount was set in an appendfile
3092 transport
3093
3094 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3095 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3096 place.
3097
3098 3. Give more explanation in the error message when the command for a transport
3099 filter fails to execute.
3100
3101 4. There are several places where Exim runs a non-Exim command in a
3102 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3103 was being done only for the command run by the queryprogram router. It is
3104 now done for all such subprocesses. The other cases are: ${run, transport
3105 filters, and the commands run by the lmtp and pipe transports.
3106
3107 5. Some older OS have a limit of 256 on the maximum number of file
3108 descriptors. Exim was using setrlimit() to set 1000 as a large value
3109 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3110 systems. I've change it so that if it can't get 1000, it tries for 256.
3111
3112 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3113 was an oversight, and furthermore, ever since the addition of extra
3114 controls (e.g. 4.43/32), the checks on when to allow different forms of
3115 "control" were broken. There should now be diagnostics for all cases when a
3116 control that does not make sense is encountered.
3117
3118 7. $recipients is now available in the predata ACL (oversight).
3119
3120 8. Tidy the search cache before the fork to do a delivery from a message
3121 received from the command line. Otherwise the child will trigger a lookup
3122 failure and thereby defer the delivery if it tries to use (for example) a
3123 cached ldap connection that the parent has called unbind on.
3124
3125 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3126 of $address_data from the recipient verification was clobbered by the
3127 sender verification.
3128
312910. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3130 was its contents. (It was OK if the option was not defined at all.)
3131
313211. A "Completed" log line is now written for messages that are removed from
3133 the spool by the -Mrm option.
3134
313512. $host_address is now set to the target address during the checking of
3136 ignore_target_hosts.
3137
313813. When checking ignore_target_hosts for an ipliteral router, no host name was
3139 being passed; this would have caused $sender_host_name to have been used if
3140 matching the list had actually called for a host name (not very likely,
3141 since this list is usually IP addresses). A host name is now passed as
3142 "[x.x.x.x]".
3143
314414. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3145 code that specifies a non-restarting handler (typically sigaction() in
3146 modern systems) in an attempt to fix a rare and obscure crash bug.
3147
314815. Narrowed the window for a race in the daemon that could cause it to ignore
3149 SIGCHLD signals. This is not a major problem, because they are used only to
3150 wake it up if nothing else does.
3151
315216. A malformed maildirsize file could cause Exim to calculate negative values
3153 for the mailbox size or file count. Odd effects could occur as a result.
3154 The maildirsize information is now recalculated if the size or filecount
3155 end up negative.
3156
315717. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3158 support for a long time. Removed HAVE_SYS_VFS_H.
3159
ea3a6f44 316018. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3161
316219. Allow an empty sender to be matched against a lookup in an address list.
3163 Previously the only cases considered were a regular expression, or an
3164 empty pattern.
3165
316620. Exim went into a mad DNS lookup loop when doing a callout where the
3167 host was specified on the transport, if the DNS lookup yielded more than
3168 one IP address.
3169
ea3a6f44
NM
317021. The RFC2047 encoding function was originally intended for short strings
3171 such as real names; it was not keeping to the 75-character limit for
3172 encoded words that the RFC imposes. It now respects the limit, and
3173 generates multiple encoded words if necessary. To be on the safe side, I
3174 have increased the buffer size for the ${rfc2047: expansion operator from
3175 1024 to 2048 bytes.
bbe902f0 3176
ea3a6f44
NM
317722. Failure to deliver a bounce message always caused it to be frozen, even if
3178 there was an errors_to setting on the router. The errors_to setting is now
3179 respected.

318123. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3182 canonical form (fully expanded) before being placed in
3183 $sender_host_address.

318524. Updated eximstats to version 1.33

318725. Include certificate and key file names in error message when GnuTLS fails
3188 to set them up, because the GnuTLS error message doesn't include the name
3189 of the failing file when there is a problem reading it.

319728. exim_tidydb, when checking for the continued existence of a message for
3198 which it has found a message-specific retry record, was not finding
3199 messages that were in split spool directories. Consequently, it was
3200 deleting retry records that should have stayed in existence.

320229. eximstats updated to version 1.35

320630. The SPA authentication driver was not abandoning authentication and moving
3207 on to the next authenticator when an expansion was forced to fail,
3208 contradicting the general specification for all authenticators. Instead it
3209 was generating a temporary error. It now behaves as specified.

321131. The default ordering of permitted cipher suites for GnuTLS was pessimal
3212 (the order specifies the preference for clients). The order is now AES256,
3213 AES128, 3DES, ARCFOUR128.

321832. Exim crashed if a remote delivery caused a very long error message to be
3219 recorded - for instance if somebody sent an entire SpamAssassin report back
3220 as a large number of 550 error lines. This bug was coincidentally fixed by
3221 increasing the size of one of Exim's internal buffers (big_buffer) that
3222 happened as part of the Exiscan merge. However, to be on the safe side, I
3223 have made the code more robust (and fixed the comments that describe what
3224 is going on).

322633. Some experimental protocols are using DNS PTR records for new purposes. The
3227 keys for these records are domain names, not reversed IP addresses. The
3228 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3229 leaves it alone. Component reversal etc. now happens only for IP addresses.

323234. The host_aton() function is supposed to be passed a string that is known
3233 to be a valid IP address. However, in the case of IPv6 addresses, it was
3234 not checking this. This is a hostage to fortune. Exim now panics and dies
3235 if the condition is not met. A case was found where this could be provoked
3236 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3237 components; fortuitously, this particular loophole had already been fixed
3238 by change 4.50/55 or 4.44/33 above.
3239
3240 If there are any other similar loopholes, the new check in host_aton()
3241 itself should stop them being exploited. The report I received stated that
3242 data on the command line could provoke the exploit when Exim was running as
3243 exim, but did not say which command line option was involved. All I could
3244 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3245 running as the user.

324835. There was a buffer overflow vulnerability in the SPA authentication code

325336. The daemon start-up calls getloadavg() while still root for those OS that
3254 need the first call to be done as root, but it missed one case: when
3255 deliver_queue_load_max is set with deliver_drop_privilege. This is
3256 necessary for the benefit of the queue runner, because there is no re-exec
3257 when deliver_drop_privilege is set.
bbe902f0 3258

325937. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3260 was in use, was not putting the data itself into the right store pool;
3261 consequently, it could be overwritten for a subsequent message in the same
3262 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3263 the caching.)

326538. Sometimes the final signoff response after QUIT could fail to get
3266 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3267 < 0 before doing a fflush(). This bug looks as though it goes back to the
3268 introduction of TLS in release 3.20, but "sometimes" must have been rare
3269 because the tests only now provoked it.

3272Exim version 4.43
3273-----------------
3274
3275 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3276 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3277 Now it returns an integer. A number of calls were still expecting a T/F
3278 return. Fortuitously, in all cases, the tests worked in OK situations,
3279 which is the norm. However, things would have gone wrong on any write
3280 failures on the smtp file descriptor. This function is used when sending
3281 messages over SMTP and also when doing verify callouts.
3282
3283 2. When Exim is called to do synchronous delivery of a locally submitted
3284 message (the -odf or -odi options), it no longer closes stderr before doing
3285 the delivery.
3286
3287 3. Implemented the mua_wrapper option.
3288
3289 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3290
3291 5. Implemented the functions header_remove(), header_testname(),
3292 header_add_at_position(), and receive_remove_recipient(), and exported them
3293 to local_scan().
3294
3295 6. If an ACL "warn" statement specified the addition of headers, Exim already
3296 inserted X-ACL-Warn: at the start if there was no header name. However, it
3297 was not making this test for the second and subsequent header lines if
3298 there were newlines in the string. This meant that an invalid header could
3299 be inserted if Exim was badly configured.
3300
3301 7. Allow an ACL "warn" statement to add header lines at the start or after all
3302 the Received: headers, as well as at the end.
3303
3304 8. Added the rcpt_4xx retry error code.
3305
3306 9. Added postmaster_mailfrom=xxx to callout verification option.
3307
330810. Added mailfrom=xxxx to the callout verification option, for verify=
3309 header_sender only.
3310
331111. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3312 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3313
331412. Inserted some casts to stop certain compilers warning when using pointer
3315 differences as field lengths or precisions in printf-type calls (mostly
3316 affecting debugging statements).
3317
331813. Added optional readline() support for -be (dynamically loaded).
3319
332014. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3321 same clock tick as a message's arrival, so that its received time was the
3322 same as the "first fail" time on the retry record, and that message
3323 remained on the queue past the ultimate address timeout, every queue runner
3324 would try a delivery (because it was past the ultimate address timeout) but
3325 after another failure, the ultimate address timeout, which should have then
3326 bounced the address, did not kick in. This was a "< instead of <=" error;
3327 in most cases the first failure would have been in the next clock tick
3328 after the received time, and all would be well.
3329
333015. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3331 being recognized when the domain list was tested by the match_domain
3332 condition in an expansion string.
3333
333416. Added the ${str2b64: operator.
3335
333617. Exim was always calling setrlimit() to set a large limit for the number of
3337 processes, without checking whether the existing limit was already
3338 adequate. (It did check for the limit on file descriptors.) Furthermore,
3339 errors from getrlimit() and setrlimit() were being ignored. Now they are
3340 logged to the main and panic logs, but Exim does carry on, to try to do its
3341 job under whatever limits there are.
3342
334318. Imported PCRE 5.0.
3344
334519. Trivial typo in log message " temporarily refused connection" (the leading
3346 space).
3347
334820. If the log selector return_path_on_delivery was set and an address was
3349 redirected to /dev/null, the delivery process crashed because it assumed
3350 that a return path would always be set for a "successful" delivery. In this
3351 case, the whole delivery is bypassed as an optimization, and therefore no
3352 return path is set.
3353
335421. Internal re-arrangement: the function for sending a challenge and reading
3355 a response while authentication was assuming a zero-terminated challenge
3356 string. It's now changed to take a pointer and a length, to allow for
3357 binary data in such strings.
3358
335922. Added the cyrus_sasl authenticator (code supplied by MBM).
3360
336123. Exim was not respecting finduser_retries when seeking the login of the
3362 uid under which it was called; it was always trying 10 times. (The default
3363 setting of finduser_retries is zero.) Also, it was sleeping after the final
3364 failure, which is pointless.
3365
336624. Implemented tls_on_connect_ports.
3367
336825. Implemented acl_smtp_predata.
3369
337026. If the domain in control=submission is set empty, Exim assumes that the
3371 authenticated id is a complete email address when it generates From: or
3372 Sender: header lines.
3373
337427. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3375 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3376 chown and chgrp in /bin and hostname in /usr/bin.
3377
337828. Exim was keeping the "process log" file open after each use, just as it
3379 does for the main log. This opens the possibility of it remaining open for
3380 long periods when the USR1 signal hits a daemon. Occasional processlog
3381 errors were reported, that could have been caused by this. Anyway, it seems
3382 much more sensible not to leave this file open at all, so that is what now
3383 happens.
3384
338529. The long-running daemon process does not normally write to the log once it
3386 has entered its main loop, and it closes the log before doing so. This is
3387 so that log files can straightforwardly be renamed and moved. However,
3388 there are a couple of unusual error situations where the daemon does write
3389 log entries, and I had neglected to close the log afterwards.
3390
339130. The text of an SMTP error response that was received during a remote
3392 delivery was being truncated at 512 bytes. This is too short for some of
3393 the long messages that one sometimes sees. I've increased the limit to
3394 1024.
3395
339631. It is now possible to make retry rules that apply only when a message has a
3397 specific sender, in particular, an empty sender.
3398
339932. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3400 it possible to be selective about when SMTP synchronization is enforced.
3401
340233. Added "control = caseful_local_part" and "control = "caselower_local_part".
3403
340432. Implemented hosts_connection_nolog.
3405
340633. Added an ACL for QUIT.
3407
340834. Setting "delay_warning=" to disable warnings was not working; it gave a
3409 syntax error.
3410
341135. Added mailbox_size and mailbox_filecount to appendfile.
3412
341336. Added control = no_multiline_responses to ACLs.
3414
341537. There was a bug in the logic of the code that waits for the clock to tick
3416 in the case where the clock went backwards by a substantial amount such
3417 that the microsecond fraction of "now" was more than the microsecond
3418 fraction of "then" (but the whole seconds number was less).
3419
342038. Added support for the libradius Radius client library this is found on
3421 FreeBSD (previously only the radiusclient library was supported).
3422
3423
3424Exim version 4.42
3425-----------------
3426
3427 1. When certain lookups returned multiple values in the form name=value, the
3428 quoting of the values was not always being done properly. Specifically:
3429 (a) If the value started with a double quote, but contained no whitespace,
