76PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.

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

416 Note to Michael Haardt: I had to rename some vars in sieve.c. They
417 were called 'true' and it seems that C99 defines that as a reserved

419 not include C99-style headers which use bools without triggering

PH
440PH/02 When an IPv6 address is converted to a string for single-key lookup
441 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
442 dots are used instead of colons so that keys in lsearch files need not
443 contain colons. This was done some time before quoting was made available
444 in lsearch files. However, iplsearch files do require colons in IPv6 keys
445 (notated using the quote facility) so as to distinguish them from IPv4
446 keys. This meant that lookups for IP addresses in host lists did not work
447 for iplsearch lookups.
448
449 This has been fixed by arranging for IPv6 addresses to be expressed with
450 colons if the lookup type is iplsearch. This is not incompatible, because
451 previously such lookups could never work.
452
453 The situation is now rather anomolous, since one *can* have colons in
454 ordinary lsearch keys. However, making the change in all cases is
455 incompatible and would probably break a number of configurations.

460MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
461 conversion specification without a maximum field width, thereby enabling
462 a rogue spamd server to cause a buffer overflow. While nobody in their
463 right mind would setup Exim to query an untrusted spamd server, an
464 attacker that gains access to a server running spamd could potentially
465 exploit this vulnerability to run arbitrary code as the Exim user.

MH
470MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
471 a directory entry by the name of the lookup key. Previously, if a
472 symlink pointed to a non-existing file or a file in a directory that
473 Exim lacked permissions to read, a lookup for a key matching that
474 symlink would fail. Now it is enough that a matching directory entry
475 exists, symlink or not. (Bugzilla 503.)

PH
658PH/29 SMTP synchronization checks are implemented when a command is read -
659 there is a check that no more input is waiting when there shouldn't be
660 any. However, for some commands, a delay in an ACL can mean that it is
661 some time before the response is written. In this time, more input might
662 arrive, invalidly. So now there are extra checks after an ACL has run for
663 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
664 pipelining has not been advertised.

679 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
680 was a macro that became an assignment, so it seemed to work. This has

PH
738 the response to the final '.' that terminates a message, but only in the
739 case where the client has not sent further data following the '.'
740 (unfortunately, this is allowed). However, in many cases there won't be
741 any further data because there won't be any more messages to send. A call
742 to select() can be used: if it shows that the input is "ready", there is
743 either input waiting, or the socket has been closed. An attempt to read
744 the next input character can distinguish the two cases. Previously, Exim
58eb016e 745 would have sent an OK response which the client would never have see.

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

801TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
802 processing considerably. Previous code took too long for large mails,
803 triggering a timeout which in turn triggers #401.
804
805TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
806 in the DK code in transports.c. sendfile() is not really portable,
807 hence the _LINUX specificness.

809TF/01 In the add_headers option to the mail command in an Exim filter,
810 there was a bug that Exim would claim a syntax error in any
811 header after the first one which had an odd number of characters
812 in the field name.

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

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

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

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

894PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
895 look up a TXT record in a specific list after matching in a combined
896 list.
897
322050c2
PH
898PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
899 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
900 they consult the DNS. I had assumed they would set it the way they
901 wanted; and indeed my experiments on Linux seem to show that in some
902 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
903 To be on the safe side, however, I have now made the interface to
904 host_find_byname() similar to host_find_bydns(), with an argument
905 containing the DNS resolver options. The host_find_byname() function now
906 sets these options at its start, just as host_find_bydns() does. The smtp
907 transport options dns_qualify_single and dns_search_parents are passed to
908 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
909 of host_find_byname() use the default settings of RES_DEFNAMES
910 (qualify_single) but not RES_DNSRCH (search_parents).

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

PH
920PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
921 flag allowing group syntax was set by the header_syntax check but not
922 turned off, possible causing trouble later; (2) The flag was not being
923 set at all for the header_verify test, causing "group"-style headers to
924 be rejected. I have now set it in this case, and also caused header_
925 verify to ignore an empty address taken from a group. While doing this, I
926 came across some other cases where the code for allowing group syntax
927 while scanning a header line wasn't quite right (mostly, not resetting
928 the flag correctly in the right place). These bugs could have caused
929 trouble for malformed header lines. I hope it is now all correct.

PH
931PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
932 with the "reply" argument non-NULL. The code, however (which originally
933 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
934 but it didn't always do it. This confused somebody who was copying the
935 code for some other use. I have removed all the tests.
936
411ef850
PH
937PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
938 feature that was used to support insecure browsers during the U.S. crypto
939 embargo. It requires special client support, and Exim is probably the
940 only MTA that supported it -- and would never use it because real RSA is
941 always available. This code has been removed, because it had the bad
942 effect of slowing Exim down by computing (never used) parameters for the
943 RSA_EXPORT functionality.
944
7befa435
PH
945PH/21 On the advice of Timo Sirainen, added a check to the dovecot
946 authenticator to fail if there's a tab character in the incoming data
947 (there should never be unless someone is messing about, as it's supposed
948 to be base64-encoded). Also added, on Timo's advice, the "secured" option
949 if the connection is using TLS or if the remote IP is the same as the
950 local IP, and the "valid-client-cert option" if a client certificate has
951 been verified.

PH
982
983PH/30 Exim was sometimes attempting to deliver messages that had suffered
984 address errors (4xx response to RCPT) over the same connection as other
985 messages routed to the same hosts. Such deliveries are always "forced",
986 so retry times are not inspected. This resulted in far too many retries
987 for the affected addresses. The effect occurred only when there were more
988 hosts than the hosts_max_try setting in the smtp transport when it had
989 the 4xx errors. Those hosts that it had tried were not added to the list
990 of hosts for which the message was waiting, so if all were tried, there
991 was no problem. Two fixes have been applied:
992
993 (i) If there are any address or message errors in an SMTP delivery, none
994 of the hosts (tried or untried) are now added to the list of hosts
995 for which the message is waiting, so the message should not be a
996 candidate for sending over the same connection that was used for a
997 successful delivery of some other message. This seems entirely
998 reasonable: after all the message is NOT "waiting for some host".
999 This is so "obvious" that I'm not sure why it wasn't done
1000 previously. Hope I haven't missed anything, but it can't do any
1001 harm, as the worst effect is to miss an optimization.
1002
1003 (ii) If, despite (i), such a delivery is accidentally attempted, the
1004 routing retry time is respected, so at least it doesn't keep
1005 hammering the server.

PH
1020PH/35 The error "getsockname() failed: connection reset by peer" was being
1021 written to the panic log as well as the main log, but it isn't really
1022 panic-worthy as it just means the connection died rather early on. I have
1023 removed the panic log writing for the ECONNRESET error when getsockname()
1024 fails.
1025
48c7f9e2
PH
1026PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1027 runs only) independently of the message's sender address. This meant
1028 that, if the 4xx error was in fact related to the sender, a different
1029 message to the same recipient with a different sender could confuse
1030 things. In particualar, this can happen when sending to a greylisting
1031 server, but other circumstances could also provoke similar problems.
1032 I have changed the default so that the retry time for these errors is now
1033 based a combination of the sender and recipient addresses. This change
1034 can be overridden by setting address_retry_include_sender=false in the
1035 smtp transport.

1037PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

1303PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1304 "Deny" causes Exim to reject the incoming connection with a 554 error.
1305 Unfortunately, if there is a major crisis, such as a disk failure,
1306 tcp-wrappers gives "deny", whereas what one would like would be some
1307 kind of temporary error. A kludge has been added to help with this.
1308 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1309 554 error is used if errno is still zero or contains ENOENT (which occurs
1310 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1311 451 error is used.

1347PH/01 The code for finding all the local interface addresses on a FreeBSD
1348 system running IPv6 was broken. This may well have applied to all BSD
1349 systems, as well as to others that have similar system calls. The broken
1350 code found IPv4 interfaces correctly, but gave incorrect values for the
1351 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1352 that it would not match correctly against @[] and not recognize the IPv6
1353 addresses as local.

1396 autoreply, Exim could try to deliver to a non-existent relative file
1397 name, causing unrelated and misleading errors. What now happens is that

1419 (a) Failures to set uid/gid, the current directory, or a process leader
1420 in a subprocess such as that created by queryprogram now generate
1421 suitable debugging ouput when -d is set.
1422

1425 the subprocess without attempting to change uid/gid.

1431 additional section of a DNS packet that returns MX or SRV records.
1432 Instead, it always explicitly searches for A/AAAA records. This avoids
1433 major problems that occur when a DNS server includes only records of one
1434 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1435 fixed another bug: if SRV records were looked up and the corresponding
1436 address records were *not* found in the additional section, the port
1437 values from the SRV records were lost.

1439PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1447PH/19 When calculating a retry time, Exim used to measure the "time since
1448 failure" by looking at the "first failed" field in the retry record. Now
1449 it does not use this if it is later than than the arrival time of the
1450 message. Instead it uses the arrival time. This makes for better
1451 behaviour in cases where some deliveries succeed, thus re-setting the
1452 "first failed" field. An example is a quota failure for a huge message
1453 when small messages continue to be delivered. Without this change, the
1454 "time since failure" will always be short, possible causing more frequent
1455 delivery attempts for the huge message than are intended.

1552PH/42 The content-scanning code uses fopen() to create files in which to put

1555 files with open(), and sets the required mode explicitly. Thus, these
1556 files were ending up world-writeable. This was not a big issue, because,
1557 being within the spool directory, they were not world-accessible. I have
1558 created a function called modefopen, which takes an additional mode
1559 argument. It sets umask(777), creates the file, chmods it to the required
1560 mode, then resets the umask. All the relevant calls to fopen() in the

1587PH/50 When an Exim quota was set without a file count quota, and mailbox_size
1588 was also set, the appendfile transport was unnecessarily scanning a
1589 directory of message files (e.g. for maildir delivery) to find the count
1590 of files (along with the size), even though it did not need this
1591 information. It now does the scan only if it needs to find either the

1596PH/52 Two bugs concerned with error handling when the smtp transport is
1597 used in LMTP mode:
1598
1599 (i) Exim was not creating retry information for temporary errors given
1600 for individual recipients after the DATA command when the smtp transport
1601 was used in LMTP mode. This meant that they could be retried too
1602 frequently, and not timed out correctly.
1603
1604 (ii) Exim was setting the flag that allows error details to be returned
1605 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1606 recipients that were returned after the DATA command.
1607
1608PH/53 This is related to PH/52, but is more general: for any failing address,
1609 when detailed error information was permitted to be returned to the
1610 sender, but the error was temporary, then after the final timeout, only
1611 "retry timeout exceeded" was returned. Now it returns the full error as
1612 well as "retry timeout exceeded".

1671 been fixed. However, if bounce_return_message is true and bounce_return_
1672 body is false, the headers that are returned for a non-SMTP message
1673 include only those that have been read before the error was detected.

PH
1682PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1683 function verify_get_ident() calls ip_connect() to connect a socket, but
1684 if the "connect()" function timed out, ip_connect() used to close the
1685 socket. However, verify_get_ident() also closes the socket later, and in
1686 between Exim writes to the log, which may get opened at this point. When
1687 the socket was closed in ip_connect(), the log could get the same file
1688 descriptor number as the socket. This naturally causes chaos. The fix is
1689 not to close the socket in ip_connect(); the socket should be closed by
1690 the function that creates it. There was only one place in the code where
1691 this was missing, in the iplookup router, which I don't think anybody now
1692 uses, but I've fixed it anyway.

1711PH/02 Several tidies to the handling of ${prvs and ${prvscheck:

1713 (1) Generate an error if the third argument for the ${prvs expansion is
1714 not a single digit.
1715
1716 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1717 string.
1718
1719 (3) Reset the variables that are obtained from the first argument of
1720 ${prvscheck and used in the second argument before leaving the code,
1721 because their memory is reclaimed, so using them afterwards may do
1722 silly things.
1723
1724 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1725 one (it's much easier than Tom thought :-).
1726
1727 (5) Because of (4), we can now allow for the use of $prvscheck_result
1728 inside the third argument.

1741
1742 This has been changed so that it extracts the operative address. There
1743 may be more than one such address. If so, they are comma-separated, like
1744 this:

PH
1748PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1749 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1750 not being looked up in the rDNS to get a host name, Exim was showing the
1751 IP address twice in Received: lines, even though the IP addresses were
1752 identical. For example:
1753
1754 Received: from [1.2.3.4] (helo=[1.2.3.4])
1755
1756 However, if the real host name was known, it was omitting the HELO data
1757 if it matched the actual IP address. This has been tidied up so that it
1758 doesn't show the same IP address twice.

1760PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
1784PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
1785 Electronic Mail") by including:
1786
1787 Auto-submitted: auto-generated
1788
1789 in the messages that it generates (bounce messages and others, such as
1790 warnings). In the case of bounce messages for non-SMTP mesages, there was
1791 also a typo: it was using "Auto_submitted" (underscore instead of
1792 hyphen). Since every message generated by Exim is necessarily in response
1793 to another message, thes have all been changed to:
1794
1795 Auto-Submitted: auto-replied
1796
1797 in accordance with these statements in the RFC:
1798
1799 The auto-replied keyword:
1800
1801 - SHOULD be used on messages sent in direct response to another
1802 message by an automatic process,
1803
1804 - MUST NOT be used on manually-generated messages,
1805
1806 - MAY be used on Delivery Status Notifications (DSNs) and Message
1807 Disposition Notifications (MDNs),

1809 - MUST NOT be used on messages generated by automatic or periodic
1810 processes, except for messages which are automatic responses to
1811 other messages.

1847PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1848 canonical form (as documented). However, after a host name lookup from
1849 the IP address, check_host() was doing a simple string comparison with
1850 addresses acquired from the DNS when checking that the found name did
1851 have the original IP as one of its addresses. Since any found IPv6
1852 addresses are likely to be in abbreviated form, the comparison could
1853 fail. Luckily, there already exists a function for doing the comparison
1854 by converting both addresses to binary, so now that is used instead of
1855 the text comparison.

PH
1857PH/20 There was another similar case to PH/19, when a complete host name was

2153 with the definition in sysexits.h (which is #included earlier).
2154 Fortunately, Exim does not actually use EX_OK. The code used to try to
2155 preserve the sysexits.h value, by assumimg that macro definitions were
2156 scanned for macro replacements. I have been disabused of this notion,

2164 doesn't have to be particularly precise.

2240 case the guess is not the same as the compiled default, so the script
2241 suddenly stopped working when I started to use syslog. The patch checks

2374 that changes the way the GnuTLS parameters are stored in the cache file.
2375 The new format can be generated externally. For backward compatibility,
2376 if the data in the cache doesn't make sense, Exim assumes it has read an
2377 old-format file, and it generates new data and writes a new file. This
2378 means that you can't go back to an older release without removing the
2379 file.
2380
2381PH/03 A redirect router that has both "unseen" and "one_time" set does not
2382 work if there are any delivery delays because "one_time" forces the

2384 again. For this reason, Exim now forbids the simultaneous setting of

2387PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2388 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2389 entry if you want to know the details. The fix, however, neglected to
2390 consider the case when local delivery batching is involved. The test for
2391 "previously delivered" was not happening when checking to see if an
2392 address could be batched with a previous (undelivered) one; under
2393 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2394 address.

PH
2395
2396PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2397 in its include files, and this causes problems building Exim.
2398
2399PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2400 header_syntax) but Exim was just ignoring anything given after a slash.
2401 In particular, this caused confusion with an attempt to use "verify =
2402 reverse_host_lookup/defer_ok". An error is now given when options are
2403 supplied for verify items that do not have them. (Maybe reverse_host_
2404 lookup should have a defer_ok option, but that's a different point.)
2405
2406PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2407 defined by RFC 821) to 2048, because there were problems with some AUTH
2408 commands, and RFC 1869 says the size should be increased for extended
2409 SMTP commands that take arguments.

2411PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
2412 Finch).

PH
2456PH/19 When an Exim process that is running as root has to create an Exim log
2457 file, it does so in a subprocess that runs as exim:exim so as to get the
2458 ownership right at creation (otherwise, other Exim processes might see
2459 the file with the wrong ownership). There was no test for failure of this
2460 fork() call, which would lead to the process getting stuck as it waited
2461 for a non-existent subprocess. Forks do occasionally fail when resources
2462 run out. I reviewed all the other calls to fork(); they all seem to check
2463 for failure.

PH
2465PH/20 When checking for unexpected SMTP input at connect time (before writing
2466 the banner), Exim was not dealing correctly with a non-positive return
2467 from the read() function. If the client had disconnected by this time,
2468 the result was a log entry for a synchronization error with an empty
2469 string after "input=" when read() returned zero. If read() returned -1
2470 (an event I could not check), uninitialized data bytes were printed.
2471 There were reports of junk text (parts of files, etc) appearing after

c5ddb310
PH
2482PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2483 hadn't been configured. The fix is from Juergen Kreileder, who
2484 understands it better than I do:
2485
2486 "Here's what I see happening with three configured cyrus_sasl
2487 authenticators configured (plain, login, cram-md5):
2488
2489 On startup auth_cyrus_sasl_init() gets called for each of these.
2490 This means three calls to sasl_listmech() without a specified mech_list.
2491 => SASL tests which mechs of all available mechs actually work
2492 => three warnings about OTP not working
2493 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2494
2495 With the patch, sasl_listmech() also gets called three times. But now
2496 SASL's mech_list option is set to the server_mech specified in the the
2497 authenticator. Or in other words, the answer from sasl_listmech()
2498 gets limited to just the mech you're testing for (which is different
2499 for each call.)
2500 => the return list contains just 'plain' or 'login', 'cram-md5' or
2501 nothing depending on the value of ob->server_mech.
2502
2503 I've just tested the patch: Authentication still works fine,
2504 unavailable mechs specified in the exim configuration are still
2505 caught, and the auth.log warnings about OTP are gone."

PH
2569PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2570 the grounds that routing the same address twice would always produce the
2571 same answer. This might have been true once, but it is certainly no
2572 longer true now. Routing a child address may depend on the previous
2573 routing that produced that child. Some complicated redirection strategies
2574 went wrong when messages had multiple recipients, and made Exim's
2575 behaviour dependent on the order in which the addresses were given.
2576
2577 I have moved the duplicate checking until after the routing is complete.
2578 Exim scans the addresses that are assigned to local and remote
2579 transports, and removes any duplicates. This means that more work will be
2580 done, as duplicates will always all be routed, but duplicates are
2581 presumably rare, so I don't expect this is of any significance.
2582
2583 For deliveries to pipes, files, and autoreplies, the duplicate checking
2584 still happens during the routing process, since they are not going to be
2585 routed further.

2626PH/45 In a pipe transport, although a timeout while waiting for the pipe

2629 successful delivery. Such timeouts include transport filter timeouts. For
2630 consistency with the overall process timeout, these timeouts are now
2631 treated as errors, giving rise to delivery failures by default. However,
2632 there is now a new Boolean option for the pipe transport called
2633 timeout_defer, which, if set TRUE, converts the failures into defers for
2634 both kinds of timeout. A transport filter timeout is now identified in

2644A note about Exim versions 4.44 and 4.50
2645----------------------------------------
2646
2647Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2648changes of various kinds. As a consequence, a big documentation update was
2649needed. This delayed the release for rather longer than seemed good, especially
2650in the light of a couple of (minor) security issues. Therefore, the changes
2651that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2652release. So 4.44 and 4.50 are in effect two different branches that both start
2653from 4.43.
2654
2655I have left the 4.50 change log unchanged; it contains all the changes since
26564.43. The change log for 4.44 is below; many of its items are identical to
2657those for 4.50. This seems to be the most sensible way to preserve the
2658historical information.

2676 5. There are several places where Exim runs a non-Exim command in a
2677 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2678 was being done only for the command run by the queryprogram router. It is
2679 now done for all such subprocesses. The other cases are: ${run, transport
2680 filters, and the commands run by the lmtp and pipe transports.

2685 descriptors. Exim was using setrlimit() to set 1000 as a large value
2686 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2687 systems. I've change it so that if it can't get 1000, it tries for 256.

2736
273723. When checking ignore_target_hosts for an ipliteral router, no host name was
2738 being passed; this would have caused $sender_host_name to have been used if
2739 matching the list had actually called for a host name (not very likely,

2741 "[x.x.x.x]".

2746
274725. Narrowed the window for a race in the daemon that could cause it to ignore

2762 subject address (from a bounce message) matched only if the pattern was an
2763 empty string. Non-empty patterns were not even tested. This was the wrong
2764 because it is perfectly reasonable to use an empty address as part of a
2765 database query. An empty address is now tested by patterns that are
2766 lookups. However, all the other forms of pattern expect the subject to
2767 contain a local part and a domain, and therefore, for them, an empty
2768 address still always fails if the pattern is not itself empty.

277932. The RFC2047 encoding function was originally intended for short strings
2780 such as real names; it was not keeping to the 75-character limit for
2781 encoded words that the RFC imposes. It now respects the limit, and
2782 generates multiple encoded words if necessary. To be on the safe side, I
2783 have increased the buffer size for the ${rfc2047: expansion operator from
2784 1024 to 2048 bytes.
2785
063b1e99
PH
278633. It is now permitted to omit both strings after an "if" condition; if the
2787 condition is true, the result is "true". As before, when the second string
2788 is omitted, a false condition yields an empty string. This makes it less
2789 cumbersome to write custom ACL and router conditions.
2790
652e1b65
PH
279134. Failure to deliver a bounce message always caused it to be frozen, even if
2792 there was an errors_to setting on the router. The errors_to setting is now
2793 respected.
2794
6f0c9a4f
PH
279535. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2796 canonical form (fully expanded) before being placed in
2797 $sender_host_address.
2798
33397d19
PH
279936. The table in the code that translates DNS record types into text (T_A to
2800 "A" for instance) was missing entries for NS and CNAME. It is just possible
2801 that this could have caused confusion if both these types were looked up
2802 for the same domain, because the text type is used as part of Exim's
2803 per-process caching. But the chance of anyone hitting this buglet seems
2804 very small.
2805
7bb56e1f
PH
280637. The dnsdb lookup has been extended in a number of ways.
2807
2808 (1) There is a new type, "zns", which walks up the domain tree until it
2809 finds some nameserver records. It should be used with care.
2810
ea3bc19b
PH
2811 (2) There is a new type, "mxh", which is like "mx" except that it returns
2812 just the host names, not the priorities.
2813
2814 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2815 looked up. The behaviour when one of the lookups defers can be
2816 controlled by a keyword.
7bb56e1f 2817
ea3bc19b 2818 (4) It is now possible to specify the separator character for use when
7bb56e1f 2819 multiple records are returned.
33397d19 2820
0bcb2a0e
PH
282138. The dnslists ACL condition has been extended: it is now possible to supply
2822 a list of IP addresses and/or domains to be looked up in a particular DNS
2823 domain.
2824
2ac0e484
PH
282539. Added log_selector=+queue_time_overall.
2826
4e1fde53
PH
282740. When running the queue in the test harness, wait just a tad after forking a
2828 delivery process, to get repeatability of debugging output.
2829
de365ded
PH
283041. Include certificate and key file names in error message when GnuTLS fails
2831 to set them up, because the GnuTLS error message doesn't include the name
2832 of the failing file when there is a problem reading it.
2833
f05da2e8
PH
283442. Allow both -bf and -bF in the same test run.

d6453af2
PH
283643. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
2837
f7b63901
PH
283844. The "Exiscan patch" is now merged into the mainline Exim source.
2839
284045. Sometimes the final signoff response after QUIT could fail to get
2841 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2842 < 0 before doing a fflush(). This bug looks as though it goes back to the
2843 introduction of TLS in release 3.20, but "sometimes" must have been rare
2844 because the tests only now provoked it.
2845
a444213a
PH
284646. Reset the locale to "C" after calling embedded Perl, in case it was changed
2847 (this can affect the format of dates).
2848
0ec020ea
PH
284947. exim_tidydb, when checking for the continued existence of a message for
2850 which it has found a message-specific retry record, was not finding
2851 messages that were in split spool directories. Consequently, it was
2852 deleting retry records that should have stayed in existence.
2853
b1206957
PH
285448. Steve fixed some bugs in eximstats.
2855
285649. The SPA authentication driver was not abandoning authentication and moving
2857 on to the next authenticator when an expansion was forced to fail,
2858 contradicting the general specification for all authenticators. Instead it
2859 was generating a temporary error. It now behaves as specified.
2860
26dd5a95
PH
286150. The default ordering of permitted cipher suites for GnuTLS was pessimal
2862 (the order specifies the preference for clients). The order is now AES256,
2863 AES128, 3DES, ARCFOUR128.
2864
343b2385
PH
286551. Small patch to Sieve code - explicitly set From: when generating an
2866 autoreply.
2867
1c5466b9
PH
286852. Exim crashed if a remote delivery caused a very long error message to be
2869 recorded - for instance if somebody sent an entire SpamAssassin report back
2870 as a large number of 550 error lines. This bug was coincidentally fixed by
2871 increasing the size of one of Exim's internal buffers (big_buffer) that
2872 happened as part of the Exiscan merge. However, to be on the safe side, I
2873 have made the code more robust (and fixed the comments that describe what
2874 is going on).
2875
55ee9ee3
PH
287653. Now that there can be additional text after "Completed" in log lines (if
2877 the queue_time_overall log selector is set), a one-byte patch to exigrep
2878 was needed to allow it to recognize "Completed" as not the last thing in
2879 the line.
2880
d38f8232
PH
288154. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2882 patch that reportedly fixes this has been added. I am not expert enough to
2883 create a test for it. This is what the patch creator wrote:
2884
2885 "I found a little strange behaviour of ldap code when working with
2886 Windows 2003 AD Domain, where users was placed in more than one
2887 Organization Units. When I tried to give exim partial DN, the exit code
2888 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2889 But simultaneously result of request was absolutely normal ldap result,
2890 so I produce this patch..."
2891
3295e65b
PH
2892 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2893 REFERENCE, so I have modified the code to exclude the patch when that macro
2894 is not defined.
2895
7102e136
PH
289655. Some experimental protocols are using DNS PTR records for new purposes. The
2897 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2898 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2899 leaves it alone. Component reversal etc. now happens only for IP addresses.
ea3a6f44 2900 CAN-2005-0021
7102e136 2901

PH
290256. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
2903
c2bcbe20
PH
290457. Double the size of the debug message buffer (to 2048) so that more of very
2905 long debug lines gets shown.
2906
18ce445d
PH
290758. The exicyclog utility now does better if the number of log files to keep
2908 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
2909
1f5b4c3d
PH
291059. Two changes related to the smtp_active_hostname option:
2911
2912 (1) $smtp_active_hostname is now available as a variable.
2913 (2) The default for smtp_banner uses $smtp_active_hostname instead
2914 of $primary_hostname.
2915
b975ba52
PH
291660. The host_aton() function is supposed to be passed a string that is known
2917 to be a valid IP address. However, in the case of IPv6 addresses, it was
2918 not checking this. This is a hostage to fortune. Exim now panics and dies
2919 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2920 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2921 components; fortuitously, this particular loophole had already been fixed
2922 by change 4.50/55 above.
2923
2924 If there are any other similar loopholes, the new check in host_aton()
2925 itself should stop them being exploited. The report I received stated that
2926 data on the command line could provoke the exploit when Exim was running as
2927 exim, but did not say which command line option was involved. All I could
2928 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2929 running as the user.
ea3a6f44 2930 CAN-2005-0021
85b87bc2
PH
2931
293261. There was a buffer overflow vulnerability in the SPA authentication code
2933 (which came originally from the Samba project). I have added a test to the
2934 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 2935 CAN-2005-0022
b975ba52 2936
17ffcae7
PH
293762. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
2938 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
2939
d95f9fdb
PH
294063. The daemon start-up calls getloadavg() while still root for those OS that
2941 need the first call to be done as root, but it missed one case: when
2942 deliver_queue_load_max is set with deliver_drop_privilege. This is
2943 necessary for the benefit of the queue runner, because there is no re-exec
2944 when deliver_drop_privilege is set.
2945
86b8287f
PH
294664. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
2947 This has been fixed.
2948
60dc5e56
PH
294965. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2950 was in use, was not putting the data itself into the right store pool;
2951 consequently, it could be overwritten for a subsequent message in the same
2952 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2953 the caching.)
2954
533244af
PH
295566. Added hosts_max_try_hardlimit to the smtp transport, default 50.
2956
a5a28604
PH
295767. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2958 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2959 the function were treating the return as a boolean value, which happened to
2960 work because 0=false and not-0=true, but is not correct code.
2961
7e634d24
PH
296268. The host_aton() function was not handling scoped IPv6 addresses (those
2963 with, for example, "%eth0" on the end) correctly.
2964
3e11c26b
PH
296569. Fixed some compiler warnings in acl.c for the bitmaps specified with
2966 negated items (that is, ~something) in unsigned ints. Some compilers
2967 apparently mutter when there is no cast.
2968
6729cf78
PH
296970. If an address verification called from an ACL failed, and did not produce a
2970 user-specific message (i.e. there was only a "system" message), nothing was
2971 put in $acl_verify_message. In this situation, it now puts the system
2972 message there.
2973
00f00ca5
PH
297471. Change 4.23/11 added synchronization checking at the start of an SMTP
2975 session; change 4.31/43 added the unwanted input to the log line - except
2976 that it did not do this in the start of session case. It now does.
2977
c9bdd01c
PH
297872. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2979 This is wrong and can cause the other end to generate a synchronization
2980 error if it is another Exim or anything else that does the synchronization
2981 check. A QUIT command is no longer sent after a timeout.
2982
d43194df
PH
298373. $host_lookup_deferred has been added, to make it easier to detect DEFERs
2984 during host lookups.
2985
fe5b5d0b
PH
298674. The defer_ok option of callout verification was not working if it was used
2987 when verifying addresses in header lines, that is, for this case:
2988
2989 verify = header_sender/callout=defer_ok
2990
76a2d7ba
PH
299175. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2992 those file descriptors could be used for SMTP connections. If anything
2993 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2994 could be sent to the SMTP client, causing chaos. The daemon now opens
2995 stdin, stdout, and stderr to /dev/null when it puts itself into the
2996 background.
2997
299876. Arrange for output from Perl's "warn" command to be written to Exim's main
2999 log by default. The user can override this with suitable Perl magic.
3000
04f7d5b9
PH
300177. The use of log_message on a "discard" ACL verb, which is supposed to add to
3002 the log message when discard triggers, was not working for the DATA ACL or
3003 for the non-SMTP ACL.
3004
bc60667e
PH
300578. Error message wording change in sieve.c.
3006
bb6e88ff
PH
300779. If smtp_accept_max_per_host was set, the number of connections could be
3008 restricted to fewer than expected, because the daemon was trying to set up
3009 a new connection before checking whether the processes handling previous
3010 connections had finished. The check for completed processes is now done
3011 earlier. On busy systems, this bug wouldn't be noticed because something
3012 else would have woken the daemon, and it would have reaped the completed
3013 process earlier.
3014
1e70f85b
PH
301580. If a message was submitted locally by a user whose login name contained one
3016 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3017 It caused a spool format error. I have fixed the spool reading code. A
3018 related problem was that the "from" clause in the Received: line became
3019 illegal because of the space(s). It is now covered by ${quote_local_part.
3020
302181. Included the latest eximstats from Steve (adds average sizes to HTML Top
3022 tables).

302482. Updated OS/Makefile-AIX as per message from Mike Meredith.

3035----------------------------------------------------
3036See the note above about the 4.44 and 4.50 releases.
3037----------------------------------------------------
3038
3039
3040Exim version 4.44
3041-----------------
3042
3043 1. Change 4.43/35 introduced a bug that caused file counts to be
3044 incorrectly computed when quota_filecount was set in an appendfile
3045 transport
3046
3047 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3048 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3049 place.
3050
3051 3. Give more explanation in the error message when the command for a transport
3052 filter fails to execute.
3053
3054 4. There are several places where Exim runs a non-Exim command in a
3055 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3056 was being done only for the command run by the queryprogram router. It is
3057 now done for all such subprocesses. The other cases are: ${run, transport
3058 filters, and the commands run by the lmtp and pipe transports.
3059
3060 5. Some older OS have a limit of 256 on the maximum number of file
3061 descriptors. Exim was using setrlimit() to set 1000 as a large value
3062 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3063 systems. I've change it so that if it can't get 1000, it tries for 256.
3064
3065 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3066 was an oversight, and furthermore, ever since the addition of extra
3067 controls (e.g. 4.43/32), the checks on when to allow different forms of
3068 "control" were broken. There should now be diagnostics for all cases when a
3069 control that does not make sense is encountered.
3070
3071 7. $recipients is now available in the predata ACL (oversight).
3072
3073 8. Tidy the search cache before the fork to do a delivery from a message
3074 received from the command line. Otherwise the child will trigger a lookup
3075 failure and thereby defer the delivery if it tries to use (for example) a
3076 cached ldap connection that the parent has called unbind on.
3077
3078 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3079 of $address_data from the recipient verification was clobbered by the
3080 sender verification.
3081
308210. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3083 was its contents. (It was OK if the option was not defined at all.)
3084
308511. A "Completed" log line is now written for messages that are removed from
3086 the spool by the -Mrm option.
3087
308812. $host_address is now set to the target address during the checking of
3089 ignore_target_hosts.
3090
309113. When checking ignore_target_hosts for an ipliteral router, no host name was
3092 being passed; this would have caused $sender_host_name to have been used if
3093 matching the list had actually called for a host name (not very likely,
3094 since this list is usually IP addresses). A host name is now passed as
3095 "[x.x.x.x]".
3096
309714. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3098 code that specifies a non-restarting handler (typically sigaction() in
3099 modern systems) in an attempt to fix a rare and obscure crash bug.
3100
310115. Narrowed the window for a race in the daemon that could cause it to ignore
3102 SIGCHLD signals. This is not a major problem, because they are used only to
3103 wake it up if nothing else does.
3104
310516. A malformed maildirsize file could cause Exim to calculate negative values
3106 for the mailbox size or file count. Odd effects could occur as a result.
3107 The maildirsize information is now recalculated if the size or filecount
3108 end up negative.
3109
311017. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3111 support for a long time. Removed HAVE_SYS_VFS_H.
3112
ea3a6f44 311318. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3114
311519. Allow an empty sender to be matched against a lookup in an address list.
3116 Previously the only cases considered were a regular expression, or an
3117 empty pattern.
3118
311920. Exim went into a mad DNS lookup loop when doing a callout where the
3120 host was specified on the transport, if the DNS lookup yielded more than
3121 one IP address.
3122
ea3a6f44
NM
312321. The RFC2047 encoding function was originally intended for short strings
3124 such as real names; it was not keeping to the 75-character limit for
3125 encoded words that the RFC imposes. It now respects the limit, and
3126 generates multiple encoded words if necessary. To be on the safe side, I
3127 have increased the buffer size for the ${rfc2047: expansion operator from
3128 1024 to 2048 bytes.
bbe902f0 3129
ea3a6f44
NM
313022. Failure to deliver a bounce message always caused it to be frozen, even if
3131 there was an errors_to setting on the router. The errors_to setting is now
3132 respected.
bbe902f0
PH
3133
313423. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3135 canonical form (fully expanded) before being placed in
3136 $sender_host_address.
3137
313824. Updated eximstats to version 1.33
3139
ea3a6f44
NM
314025. Include certificate and key file names in error message when GnuTLS fails
3141 to set them up, because the GnuTLS error message doesn't include the name
3142 of the failing file when there is a problem reading it.
bbe902f0
PH
3143
314426. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3145 As per change 25.
bbe902f0 3146
ea3a6f44
NM
314727. Reset the locale to "C" after calling embedded Perl, in case it was changed
3148 (this can affect the format of dates).
bbe902f0 3149
ea3a6f44
NM
315028. exim_tidydb, when checking for the continued existence of a message for
3151 which it has found a message-specific retry record, was not finding
3152 messages that were in split spool directories. Consequently, it was
3153 deleting retry records that should have stayed in existence.
bbe902f0
PH
3154
315529. eximstats updated to version 1.35
3156 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3157 1.35 - bugfix such that pie charts by volume are generated correctly

315930. The SPA authentication driver was not abandoning authentication and moving

317132. Exim crashed if a remote delivery caused a very long error message to be

3175 happened as part of the Exiscan merge. However, to be on the safe side, I
3176 have made the code more robust (and fixed the comments that describe what
3177 is going on).

317933. Some experimental protocols are using DNS PTR records for new purposes. The
3180 keys for these records are domain names, not reversed IP addresses. The
3181 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3182 leaves it alone. Component reversal etc. now happens only for IP addresses.

318534. The host_aton() function is supposed to be passed a string that is known
3186 to be a valid IP address. However, in the case of IPv6 addresses, it was
3187 not checking this. This is a hostage to fortune. Exim now panics and dies
3188 if the condition is not met. A case was found where this could be provoked
3189 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3190 components; fortuitously, this particular loophole had already been fixed
3191 by change 4.50/55 or 4.44/33 above.
3192
3193 If there are any other similar loopholes, the new check in host_aton()
3194 itself should stop them being exploited. The report I received stated that
3195 data on the command line could provoke the exploit when Exim was running as
3196 exim, but did not say which command line option was involved. All I could
3197 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3198 running as the user.

320135. There was a buffer overflow vulnerability in the SPA authentication code
3202 (which came originally from the Samba project). I have added a test to the
3203 spa_base64_to_bits() function which I hope fixes it.

320636. The daemon start-up calls getloadavg() while still root for those OS that
3207 need the first call to be done as root, but it missed one case: when
3208 deliver_queue_load_max is set with deliver_drop_privilege. This is
3209 necessary for the benefit of the queue runner, because there is no re-exec
3210 when deliver_drop_privilege is set.

321237. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3213 was in use, was not putting the data itself into the right store pool;
3214 consequently, it could be overwritten for a subsequent message in the same
3215 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3216 the caching.)

321838. Sometimes the final signoff response after QUIT could fail to get
3219 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3220 < 0 before doing a fflush(). This bug looks as though it goes back to the
3221 introduction of TLS in release 3.20, but "sometimes" must have been rare
3222 because the tests only now provoked it.

3225Exim version 4.43
3226-----------------
3227
3228 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3229 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3230 Now it returns an integer. A number of calls were still expecting a T/F
3231 return. Fortuitously, in all cases, the tests worked in OK situations,
3232 which is the norm. However, things would have gone wrong on any write
3233 failures on the smtp file descriptor. This function is used when sending
3234 messages over SMTP and also when doing verify callouts.
3235
3236 2. When Exim is called to do synchronous delivery of a locally submitted
3237 message (the -odf or -odi options), it no longer closes stderr before doing
3238 the delivery.
3239
3240 3. Implemented the mua_wrapper option.
3241
3242 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3243
3244 5. Implemented the functions header_remove(), header_testname(),
3245 header_add_at_position(), and receive_remove_recipient(), and exported them
3246 to local_scan().
3247
3248 6. If an ACL "warn" statement specified the addition of headers, Exim already
3249 inserted X-ACL-Warn: at the start if there was no header name. However, it
3250 was not making this test for the second and subsequent header lines if
3251 there were newlines in the string. This meant that an invalid header could
3252 be inserted if Exim was badly configured.
3253
3254 7. Allow an ACL "warn" statement to add header lines at the start or after all
3255 the Received: headers, as well as at the end.
3256
3257 8. Added the rcpt_4xx retry error code.
3258
3259 9. Added postmaster_mailfrom=xxx to callout verification option.
3260
326110. Added mailfrom=xxxx to the callout verification option, for verify=
3262 header_sender only.
3263
326411. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3265 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3266
326712. Inserted some casts to stop certain compilers warning when using pointer
3268 differences as field lengths or precisions in printf-type calls (mostly
3269 affecting debugging statements).
3270
327113. Added optional readline() support for -be (dynamically loaded).
3272
327314. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3274 same clock tick as a message's arrival, so that its received time was the
3275 same as the "first fail" time on the retry record, and that message
3276 remained on the queue past the ultimate address timeout, every queue runner
3277 would try a delivery (because it was past the ultimate address timeout) but
3278 after another failure, the ultimate address timeout, which should have then
3279 bounced the address, did not kick in. This was a "< instead of <=" error;
3280 in most cases the first failure would have been in the next clock tick
3281 after the received time, and all would be well.
3282
328315. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3284 being recognized when the domain list was tested by the match_domain
3285 condition in an expansion string.
3286
328716. Added the ${str2b64: operator.
3288
328917. Exim was always calling setrlimit() to set a large limit for the number of
3290 processes, without checking whether the existing limit was already
3291 adequate. (It did check for the limit on file descriptors.) Furthermore,
3292 errors from getrlimit() and setrlimit() were being ignored. Now they are
3293 logged to the main and panic logs, but Exim does carry on, to try to do its
3294 job under whatever limits there are.
3295
329618. Imported PCRE 5.0.
3297
329819. Trivial typo in log message " temporarily refused connection" (the leading
3299 space).
3300
330120. If the log selector return_path_on_delivery was set and an address was
3302 redirected to /dev/null, the delivery process crashed because it assumed
3303 that a return path would always be set for a "successful" delivery. In this
3304 case, the whole delivery is bypassed as an optimization, and therefore no
3305 return path is set.
3306
330721. Internal re-arrangement: the function for sending a challenge and reading
3308 a response while authentication was assuming a zero-terminated challenge
3309 string. It's now changed to take a pointer and a length, to allow for
3310 binary data in such strings.
3311
331222. Added the cyrus_sasl authenticator (code supplied by MBM).
3313
331423. Exim was not respecting finduser_retries when seeking the login of the
3315 uid under which it was called; it was always trying 10 times. (The default
3316 setting of finduser_retries is zero.) Also, it was sleeping after the final
3317 failure, which is pointless.
3318
331924. Implemented tls_on_connect_ports.
3320
332125. Implemented acl_smtp_predata.
3322
332326. If the domain in control=submission is set empty, Exim assumes that the
3324 authenticated id is a complete email address when it generates From: or
3325 Sender: header lines.
3326
332727. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3328 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3329 chown and chgrp in /bin and hostname in /usr/bin.
3330
333128. Exim was keeping the "process log" file open after each use, just as it
3332 does for the main log. This opens the possibility of it remaining open for
3333 long periods when the USR1 signal hits a daemon. Occasional processlog
3334 errors were reported, that could have been caused by this. Anyway, it seems
3335 much more sensible not to leave this file open at all, so that is what now
3336 happens.
3337
333829. The long-running daemon process does not normally write to the log once it
3339 has entered its main loop, and it closes the log before doing so. This is
3340 so that log files can straightforwardly be renamed and moved. However,
3341 there are a couple of unusual error situations where the daemon does write
3342 log entries, and I had neglected to close the log afterwards.
3343
334430. The text of an SMTP error response that was received during a remote
3345 delivery was being truncated at 512 bytes. This is too short for some of
3346 the long messages that one sometimes sees. I've increased the limit to
3347 1024.
3348
334931. It is now possible to make retry rules that apply only when a message has a
3350 specific sender, in particular, an empty sender.
3351
335232. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3353 it possible to be selective about when SMTP synchronization is enforced.
3354
335533. Added "control = caseful_local_part" and "control = "caselower_local_part".
3356
335732. Implemented hosts_connection_nolog.
3358
335933. Added an ACL for QUIT.
3360
336134. Setting "delay_warning=" to disable warnings was not working; it gave a
3362 syntax error.
3363
336435. Added mailbox_size and mailbox_filecount to appendfile.
3365
336636. Added control = no_multiline_responses to ACLs.
3367
336837. There was a bug in the logic of the code that waits for the clock to tick
3369 in the case where the clock went backwards by a substantial amount such
3370 that the microsecond fraction of "now" was more than the microsecond
3371 fraction of "then" (but the whole seconds number was less).
3372
337338. Added support for the libradius Radius client library this is found on
3374 FreeBSD (previously only the radiusclient library was supported).
3375
3376
3377Exim version 4.42
3378-----------------
3379
3380 1. When certain lookups returned multiple values in the form name=value, the
3381 quoting of the values was not always being done properly. Specifically:
3382 (a) If the value started with a double quote, but contained no whitespace,
3383 it was not quoted.
3384 (b) If the value contained whitespace other than a space character (i.e.
3385 tabs or newlines or carriage returns) it was not quoted.
3386 This fix has been applied to the mysql and pgsql lookups by writing a
3387 separate quoting function and calling it from the lookup code. The fix
3388 should probably also be applied to nisplus, ibase and oracle lookups, but
3389 since I cannot test any of those, I have not disturbed their existing code.
3390
3391 2. A hit in the callout cache for a specific address caused a log line with no
3392 reason for rejecting RCPT. Now it says "Previous (cached) callout
3393 verification failure".
3394
3395 3. There was an off-by-one bug in the queryprogram router. An over-long
3396 return line was truncated at 256 instead of 255 characters, thereby
3397 overflowing its buffer with the terminating zero. As well as fixing this, I
3398 have increased the buffer size to 1024 (and made a note to document this).
3399
3400 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3401 when Exim is waiting for an SMTP response from a remote server, Exim
3402 restarts its select() call on the socket, thereby resetting its timeout.
3403 This is not a problem when such interrupts are rare. Somebody set up a cron
3404 job to run exiwhat every 2 minutes, which is less than the normal select()
3405 timeout (5 or 10 minutes). This meant that the select() timeout never
3406 kicked in because it was always reset. I have fixed this by comparing the
3407 time when an interrupt arrives with the time at the start of the first call
3408 to select(). If more time than the timeout has elapsed, the interrupt is
3409 treated as a timeout.
3410
3411 5. Some internal re-factoring in preparation for the addition of Sieve
3412 extensions (by MH). In particular, the "personal" test is moved to a
3413 separate function, and given an option for scanning Cc: and Bcc: (which is
3414 not set for Exim filters).
3415
3416 6. When Exim created an email address using the login of the caller as the
3417 local part (e.g. when creating a From: or Sender: header line), it was not
3418 quoting the local part when it contained special characters such as @.
3419
3420 7. Installed new OpenBSD configuration files.
3421
3422 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3423 try to make them clearer.
3424
3425 9. Callout options, other than the timeout value, were being ignored when
3426 verifying sender addresses in header lines. For example, when using
3427
3428 verify = header_sender/callout=no_cache
3429
3430 the cache was (incorrectly) being used.
3431
343210. Added a missing instance of ${EXE} to the exim_install script; this affects
3433 only the Cygwin environment.
3434
343511. When return_path_on_delivery was set as a log selector, if different remote
