136PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
137 If dropping privileges for untrusted macros, we disabled normal logging

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

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

PH
500PH/02 When an IPv6 address is converted to a string for single-key lookup
501 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
502 dots are used instead of colons so that keys in lsearch files need not
503 contain colons. This was done some time before quoting was made available
504 in lsearch files. However, iplsearch files do require colons in IPv6 keys
505 (notated using the quote facility) so as to distinguish them from IPv4
506 keys. This meant that lookups for IP addresses in host lists did not work
507 for iplsearch lookups.
508
509 This has been fixed by arranging for IPv6 addresses to be expressed with
510 colons if the lookup type is iplsearch. This is not incompatible, because
511 previously such lookups could never work.
512
513 The situation is now rather anomolous, since one *can* have colons in
514 ordinary lsearch keys. However, making the change in all cases is
515 incompatible and would probably break a number of configurations.

520MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
521 conversion specification without a maximum field width, thereby enabling
522 a rogue spamd server to cause a buffer overflow. While nobody in their
523 right mind would setup Exim to query an untrusted spamd server, an
524 attacker that gains access to a server running spamd could potentially
525 exploit this vulnerability to run arbitrary code as the Exim user.

MH
530MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
531 a directory entry by the name of the lookup key. Previously, if a
532 symlink pointed to a non-existing file or a file in a directory that
533 Exim lacked permissions to read, a lookup for a key matching that
534 symlink would fail. Now it is enough that a matching directory entry
535 exists, symlink or not. (Bugzilla 503.)

718PH/29 SMTP synchronization checks are implemented when a command is read -
719 there is a check that no more input is waiting when there shouldn't be

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

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

58eb016e 797PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
798 the response to the final '.' that terminates a message, but only in the
799 case where the client has not sent further data following the '.'
800 (unfortunately, this is allowed). However, in many cases there won't be
801 any further data because there won't be any more messages to send. A call
802 to select() can be used: if it shows that the input is "ready", there is
803 either input waiting, or the socket has been closed. An attempt to read
804 the next input character can distinguish the two cases. Previously, Exim
58eb016e 805 would have sent an OK response which the client would never have see.

813Exim version 4.66
814-----------------
815
816PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
817 fixed by 4.65/MH/01 (is this a record?) are fixed:
818
819 (i) An empty string was always treated as zero by the numeric comparison
820 operators. This behaviour has been restored.
821
822 (ii) It is documented that the numeric comparison operators always treat
823 their arguments as decimal numbers. This was broken in that numbers
824 starting with 0 were being interpreted as octal.
825
826 While fixing these problems I realized that there was another issue that
827 hadn't been noticed. Values of message_size_limit (both the global option
828 and the transport option) were treated as octal if they started with 0.
829 The documentation was vague. These values are now always treated as
830 decimal, and I will make that clear in the documentation.

PH
844PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
845 child addresses, Exim now panics and dies. Previously, because the count
846 is held in a short int, deliveries were likely to be lost. As such a
847 large number of recipients for a single message is ridiculous
848 (performance will be very, very poor), I have chosen to impose a limit
849 rather than extend the field.

855TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
856 leftover -K file (the existence of which was triggered by #402).
857 While we were at it, introduced process PID as part of the -K
858 filename. This should rule out race conditions when creating
859 these files.
860
861TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
862 processing considerably. Previous code took too long for large mails,
863 triggering a timeout which in turn triggers #401.
864
865TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
866 in the DK code in transports.c. sendfile() is not really portable,

869TF/01 In the add_headers option to the mail command in an Exim filter,

871 header after the first one which had an odd number of characters
872 in the field name.
873
2b1c6e3a
PH
874PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
875 callout verification, Exim cached a "reject" for the entire domain. This
876 is correct for most verifications, but it is not correct for a recipient
877 verification with use_sender or use_postmaster set, because in that case
878 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
879 case of MAIL FROM:<> rejection from other early rejections (e.g.
880 rejection of HELO). When verifying a recipient using a non-null MAIL
881 address, the cache is ignored if it shows MAIL FROM:<> rejection.
882 Whatever the result of the callout, the value of the domain cache is
883 left unchanged (for any other kind of callout, getting as far as trying
884 RCPT means that the domain itself is ok).

918PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
919 hostname. This is wrong, because it relates to the incoming message (and
920 probably the interface on which it is arriving) and not to the outgoing
921 callout (which could be using a different interface). This has been
922 changed to use the value of the helo_data option from the smtp transport
923 instead - this is what is used when a message is actually being sent. If
924 there is no remote transport (possible with a router that sets up host
925 addresses), $smtp_active_hostname is used.
6ea85e9a 926
14aa5a05 927PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 928 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
929 (a) The code assumed that strncpy() returns a negative number on buffer
930 overflow, which isn't the case. Replaced with Exim's string_format()
931 function.
932 (b) There were several signed/unsigned issues. I just did the minimum
933 hacking in of casts. There is scope for a larger refactoring.
934 (c) The code used strcasecmp() which is not a standard C function.
935 Replaced with Exim's strcmpic() function.
936 (d) The code set only $1; it now sets $auth1 as well.
937 (e) A simple test gave the error "authentication client didn't specify
938 service in request". It would seem that Dovecot has changed its
939 interface. Fortunately there's a specification; I followed it and
940 changed what the client sends and it appears to be working now.

945PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
946 address A is aliased to B and C, where B exists and C does not. Without
947 -v the output is "A verified" because verification stops after a
948 successful redirection if more than one address is generated. However,
949 with -v the child addresses are also verified. Exim was outputting "A
950 failed to verify" and then showing the successful verification for C,
951 with its parentage. It now outputs "B failed to verify", showing B's
952 parentage before showing the successful verification of C.

955 look up a TXT record in a specific list after matching in a combined
956 list.
957
322050c2
PH
958PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
959 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
960 they consult the DNS. I had assumed they would set it the way they
961 wanted; and indeed my experiments on Linux seem to show that in some
962 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
963 To be on the safe side, however, I have now made the interface to
964 host_find_byname() similar to host_find_bydns(), with an argument
965 containing the DNS resolver options. The host_find_byname() function now
966 sets these options at its start, just as host_find_bydns() does. The smtp
967 transport options dns_qualify_single and dns_search_parents are passed to
968 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
969 of host_find_byname() use the default settings of RES_DEFNAMES
970 (qualify_single) but not RES_DNSRCH (search_parents).

972PH/17 Applied (a modified version of) Nico Erfurth's patch to make
973 spool_read_header() do less string testing, by means of a preliminary
974 switch on the second character of optional "-foo" lines. (This is
975 overdue, caused by the large number of possibilities that now exist.
976 Originally there were few.) While I was there, I also converted the
977 str(n)cmp tests so they don't re-test the leading "-" and the first
978 character, in the hope this might squeeze out yet more improvement.

PH
980PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
981 flag allowing group syntax was set by the header_syntax check but not
982 turned off, possible causing trouble later; (2) The flag was not being
983 set at all for the header_verify test, causing "group"-style headers to
984 be rejected. I have now set it in this case, and also caused header_
985 verify to ignore an empty address taken from a group. While doing this, I
986 came across some other cases where the code for allowing group syntax
987 while scanning a header line wasn't quite right (mostly, not resetting
988 the flag correctly in the right place). These bugs could have caused
989 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
991PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
992 with the "reply" argument non-NULL. The code, however (which originally
993 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
994 but it didn't always do it. This confused somebody who was copying the
995 code for some other use. I have removed all the tests.

PH
997PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
998 feature that was used to support insecure browsers during the U.S. crypto
999 embargo. It requires special client support, and Exim is probably the
1000 only MTA that supported it -- and would never use it because real RSA is
1001 always available. This code has been removed, because it had the bad
1002 effect of slowing Exim down by computing (never used) parameters for the
1003 RSA_EXPORT functionality.

PH
1005PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1006 authenticator to fail if there's a tab character in the incoming data
1007 (there should never be unless someone is messing about, as it's supposed
1008 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1009 if the connection is using TLS or if the remote IP is the same as the
1010 local IP, and the "valid-client-cert option" if a client certificate has
1011 been verified.

PH
1042
1043PH/30 Exim was sometimes attempting to deliver messages that had suffered
1044 address errors (4xx response to RCPT) over the same connection as other
1045 messages routed to the same hosts. Such deliveries are always "forced",
1046 so retry times are not inspected. This resulted in far too many retries
1047 for the affected addresses. The effect occurred only when there were more
1048 hosts than the hosts_max_try setting in the smtp transport when it had
1049 the 4xx errors. Those hosts that it had tried were not added to the list
1050 of hosts for which the message was waiting, so if all were tried, there
1051 was no problem. Two fixes have been applied:
1052
1053 (i) If there are any address or message errors in an SMTP delivery, none
1054 of the hosts (tried or untried) are now added to the list of hosts
1055 for which the message is waiting, so the message should not be a
1056 candidate for sending over the same connection that was used for a
1057 successful delivery of some other message. This seems entirely
1058 reasonable: after all the message is NOT "waiting for some host".
1059 This is so "obvious" that I'm not sure why it wasn't done
1060 previously. Hope I haven't missed anything, but it can't do any
1061 harm, as the worst effect is to miss an optimization.
1062
1063 (ii) If, despite (i), such a delivery is accidentally attempted, the
1064 routing retry time is respected, so at least it doesn't keep
1065 hammering the server.

PH
1080PH/35 The error "getsockname() failed: connection reset by peer" was being
1081 written to the panic log as well as the main log, but it isn't really
1082 panic-worthy as it just means the connection died rather early on. I have
1083 removed the panic log writing for the ECONNRESET error when getsockname()
1084 fails.
1085
48c7f9e2
PH
1086PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1087 runs only) independently of the message's sender address. This meant
1088 that, if the 4xx error was in fact related to the sender, a different
1089 message to the same recipient with a different sender could confuse
1090 things. In particualar, this can happen when sending to a greylisting
1091 server, but other circumstances could also provoke similar problems.
1092 I have changed the default so that the retry time for these errors is now
1093 based a combination of the sender and recipient addresses. This change
1094 can be overridden by setting address_retry_include_sender=false in the
1095 smtp transport.

1363PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1365 Unfortunately, if there is a major crisis, such as a disk failure,
1366 tcp-wrappers gives "deny", whereas what one would like would be some
1367 kind of temporary error. A kludge has been added to help with this.
1368 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1369 554 error is used if errno is still zero or contains ENOENT (which occurs
1370 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1371 451 error is used.

1407PH/01 The code for finding all the local interface addresses on a FreeBSD
1408 system running IPv6 was broken. This may well have applied to all BSD
1409 systems, as well as to others that have similar system calls. The broken
1410 code found IPv4 interfaces correctly, but gave incorrect values for the
1411 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1412 that it would not match correctly against @[] and not recognize the IPv6
1413 addresses as local.

1455 generate an autoreply, and therefore failed to obtain an address for the
1456 autoreply, Exim could try to deliver to a non-existent relative file
1457 name, causing unrelated and misleading errors. What now happens is that

1479 (a) Failures to set uid/gid, the current directory, or a process leader
1480 in a subprocess such as that created by queryprogram now generate
1481 suitable debugging ouput when -d is set.

1485 the subprocess without attempting to change uid/gid.

1491 additional section of a DNS packet that returns MX or SRV records.
1492 Instead, it always explicitly searches for A/AAAA records. This avoids
1493 major problems that occur when a DNS server includes only records of one
1494 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1495 fixed another bug: if SRV records were looked up and the corresponding
1496 address records were *not* found in the additional section, the port
1497 values from the SRV records were lost.

1499PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1507PH/19 When calculating a retry time, Exim used to measure the "time since
1508 failure" by looking at the "first failed" field in the retry record. Now
1509 it does not use this if it is later than than the arrival time of the
1510 message. Instead it uses the arrival time. This makes for better
1511 behaviour in cases where some deliveries succeed, thus re-setting the
1512 "first failed" field. An example is a quota failure for a huge message
1513 when small messages continue to be delivered. Without this change, the
1514 "time since failure" will always be short, possible causing more frequent
1515 delivery attempts for the huge message than are intended.

PH
1612PH/42 The content-scanning code uses fopen() to create files in which to put
1613 message data. Previously it was not paying any attention to the mode of
1614 the files. Exim runs with umask(0) because the rest of the code creates
1615 files with open(), and sets the required mode explicitly. Thus, these
1616 files were ending up world-writeable. This was not a big issue, because,
1617 being within the spool directory, they were not world-accessible. I have
1618 created a function called modefopen, which takes an additional mode
1619 argument. It sets umask(777), creates the file, chmods it to the required
1620 mode, then resets the umask. All the relevant calls to fopen() in the
1621 content scanning code have been changed to use this function.

1632 received. Setting client_ignore_invalid_base64 true ignores these errors.
1633 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1634 they are received. Thus, the responses can be made to depend on the

1656PH/52 Two bugs concerned with error handling when the smtp transport is
1657 used in LMTP mode:
1658
1659 (i) Exim was not creating retry information for temporary errors given
1660 for individual recipients after the DATA command when the smtp transport
1661 was used in LMTP mode. This meant that they could be retried too
1662 frequently, and not timed out correctly.
1663
1664 (ii) Exim was setting the flag that allows error details to be returned
1665 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1666 recipients that were returned after the DATA command.
1667
1668PH/53 This is related to PH/52, but is more general: for any failing address,
1669 when detailed error information was permitted to be returned to the
1670 sender, but the error was temporary, then after the final timeout, only
1671 "retry timeout exceeded" was returned. Now it returns the full error as
1672 well as "retry timeout exceeded".

1742PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1743 function verify_get_ident() calls ip_connect() to connect a socket, but
1744 if the "connect()" function timed out, ip_connect() used to close the
1745 socket. However, verify_get_ident() also closes the socket later, and in
1746 between Exim writes to the log, which may get opened at this point. When
1747 the socket was closed in ip_connect(), the log could get the same file
1748 descriptor number as the socket. This naturally causes chaos. The fix is
1749 not to close the socket in ip_connect(); the socket should be closed by
1750 the function that creates it. There was only one place in the code where
1751 this was missing, in the iplookup router, which I don't think anybody now
1752 uses, but I've fixed it anyway.

1775
1776 (2) Treat a missing third argument of ${prvscheck as if it were an empty

1778
1779 (3) Reset the variables that are obtained from the first argument of
1780 ${prvscheck and used in the second argument before leaving the code,
1781 because their memory is reclaimed, so using them afterwards may do
1782 silly things.
1783
1784 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1785 one (it's much easier than Tom thought :-).

1809 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1810 not being looked up in the rDNS to get a host name, Exim was showing the
1811 IP address twice in Received: lines, even though the IP addresses were
1812 identical. For example:
1813
1814 Received: from [1.2.3.4] (helo=[1.2.3.4])
1815
1816 However, if the real host name was known, it was omitting the HELO data
1817 if it matched the actual IP address. This has been tidied up so that it
1818 doesn't show the same IP address twice.

1849 in the messages that it generates (bounce messages and others, such as
1850 warnings). In the case of bounce messages for non-SMTP mesages, there was
1851 also a typo: it was using "Auto_submitted" (underscore instead of
1852 hyphen). Since every message generated by Exim is necessarily in response
1853 to another message, thes have all been changed to:
1854
1855 Auto-Submitted: auto-replied
1856
1857 in accordance with these statements in the RFC:
1858
1859 The auto-replied keyword:

1910 addresses acquired from the DNS when checking that the found name did
1911 have the original IP as one of its addresses. Since any found IPv6
1912 addresses are likely to be in abbreviated form, the comparison could
1913 fail. Luckily, there already exists a function for doing the comparison
1914 by converting both addresses to binary, so now that is used instead of
1915 the text comparison.

2213 with the definition in sysexits.h (which is #included earlier).
2214 Fortunately, Exim does not actually use EX_OK. The code used to try to
2215 preserve the sysexits.h value, by assumimg that macro definitions were
2216 scanned for macro replacements. I have been disabused of this notion,

2222 This seems wrong - if the receiver was accepting one byte at a time it
2223 would take for ever. The timeout is now adjusted when this happens. It
2224 doesn't have to be particularly precise.

2381PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2382 not automatically generating a new one, as it is supposed to. This
2383 prevented TLS from working. If the file did exist, but contained invalid
2384 data, a new version was generated, as expected. It was only the case of a
2385 non-existent file that was broken.

2432
2433PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2434 that changes the way the GnuTLS parameters are stored in the cache file.
2435 The new format can be generated externally. For backward compatibility,
2436 if the data in the cache doesn't make sense, Exim assumes it has read an
2437 old-format file, and it generates new data and writes a new file. This
2438 means that you can't go back to an older release without removing the
2439 file.
2440
2441PH/03 A redirect router that has both "unseen" and "one_time" set does not
2442 work if there are any delivery delays because "one_time" forces the
2443 parent to be marked "delivered", so its unseen clone is never tried
2444 again. For this reason, Exim now forbids the simultaneous setting of
2445 these two options.
2446
2447PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2448 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2449 entry if you want to know the details. The fix, however, neglected to
2450 consider the case when local delivery batching is involved. The test for
2451 "previously delivered" was not happening when checking to see if an
2452 address could be batched with a previous (undelivered) one; under
2453 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2454 address.

2456PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2458
2459PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2460 header_syntax) but Exim was just ignoring anything given after a slash.
2461 In particular, this caused confusion with an attempt to use "verify =
2462 reverse_host_lookup/defer_ok". An error is now given when options are
2463 supplied for verify items that do not have them. (Maybe reverse_host_
2464 lookup should have a defer_ok option, but that's a different point.)
2465
2466PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2519 the file with the wrong ownership). There was no test for failure of this
2520 fork() call, which would lead to the process getting stuck as it waited
2521 for a non-existent subprocess. Forks do occasionally fail when resources
2522 run out. I reviewed all the other calls to fork(); they all seem to check

2529 string after "input=" when read() returned zero. If read() returned -1

PH
2542PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2543 hadn't been configured. The fix is from Juergen Kreileder, who
2544 understands it better than I do:
2545
2546 "Here's what I see happening with three configured cyrus_sasl
2547 authenticators configured (plain, login, cram-md5):
2548
2549 On startup auth_cyrus_sasl_init() gets called for each of these.
2550 This means three calls to sasl_listmech() without a specified mech_list.
2551 => SASL tests which mechs of all available mechs actually work
2552 => three warnings about OTP not working
2553 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2554
2555 With the patch, sasl_listmech() also gets called three times. But now
2556 SASL's mech_list option is set to the server_mech specified in the the
2557 authenticator. Or in other words, the answer from sasl_listmech()
2558 gets limited to just the mech you're testing for (which is different
2559 for each call.)
2560 => the return list contains just 'plain' or 'login', 'cram-md5' or
2561 nothing depending on the value of ob->server_mech.
2562
2563 I've just tested the patch: Authentication still works fine,
2564 unavailable mechs specified in the exim configuration are still

PH
2629PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2630 the grounds that routing the same address twice would always produce the
2631 same answer. This might have been true once, but it is certainly no
2632 longer true now. Routing a child address may depend on the previous
2633 routing that produced that child. Some complicated redirection strategies
2634 went wrong when messages had multiple recipients, and made Exim's
2635 behaviour dependent on the order in which the addresses were given.
2636
2637 I have moved the duplicate checking until after the routing is complete.
2638 Exim scans the addresses that are assigned to local and remote
2639 transports, and removes any duplicates. This means that more work will be
2640 done, as duplicates will always all be routed, but duplicates are
2641 presumably rare, so I don't expect this is of any significance.
2642
2643 For deliveries to pipes, files, and autoreplies, the duplicate checking
2644 still happens during the routing process, since they are not going to be
2645 routed further.

2690 consistency with the overall process timeout, these timeouts are now
2691 treated as errors, giving rise to delivery failures by default. However,
2692 there is now a new Boolean option for the pipe transport called
2693 timeout_defer, which, if set TRUE, converts the failures into defers for
2694 both kinds of timeout. A transport filter timeout is now identified in

2704A note about Exim versions 4.44 and 4.50
2705----------------------------------------
2706
2707Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2708changes of various kinds. As a consequence, a big documentation update was
2709needed. This delayed the release for rather longer than seemed good, especially
2710in the light of a couple of (minor) security issues. Therefore, the changes
2711that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2712release. So 4.44 and 4.50 are in effect two different branches that both start
2713from 4.43.
2714
2715I have left the 4.50 change log unchanged; it contains all the changes since
27164.43. The change log for 4.44 is below; many of its items are identical to
2717those for 4.50. This seems to be the most sensible way to preserve the
2718historical information.

2747 systems. I've change it so that if it can't get 1000, it tries for 256.

278218. New variables $sender_verify_failure and $recipient_verify_failure contain
2783 information about exactly what failed.
2784
3d235903
PH
278519. Added -dd to debug only the daemon process.
2786
7c7ad977
PH
278720. Incorporated Michael Haardt's patch to ldap.c for improving the way it
2788 handles timeouts, both on the server side and network timeouts. Renamed the
2789 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
2790
981756db
PH
279121. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
2792 It is now set to "smtps".
2793
d4eb88df
PH
279422. $host_address is now set to the target address during the checking of
2795 ignore_target_hosts.
2796
279723. When checking ignore_target_hosts for an ipliteral router, no host name was
2798 being passed; this would have caused $sender_host_name to have been used if
2799 matching the list had actually called for a host name (not very likely,
2800 since this list is usually IP addresses). A host name is now passed as
2801 "[x.x.x.x]".
2802
7d468ab8
PH
280324. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2804 code that specifies a non-restarting handler (typically sigaction() in
2805 modern systems) in an attempt to fix a rare and obscure crash bug.
2806
280725. Narrowed the window for a race in the daemon that could cause it to ignore
2808 SIGCHLD signals. This is not a major problem, because they are used only to
2809 wake it up if nothing else does.
2810
62c0818f
PH
281126. A malformed maildirsize file could cause Exim to calculate negative values
2812 for the mailbox size or file count. Odd effects could occur as a result.
2813 The maildirsize information is now recalculated if the size or filecount
2814 end up negative.
2815
26034054
PH
281627. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
2817 support for a long time. Removed HAVE_SYS_VFS_H.
2818
af66f652
PH
281928. Installed the latest version of exipick from John Jetmore.
2820
90af77f4
PH
282129. In an address list, if the pattern was not a regular expression, an empty
2822 subject address (from a bounce message) matched only if the pattern was an
2823 empty string. Non-empty patterns were not even tested. This was the wrong
2824 because it is perfectly reasonable to use an empty address as part of a
2825 database query. An empty address is now tested by patterns that are
2826 lookups. However, all the other forms of pattern expect the subject to
2827 contain a local part and a domain, and therefore, for them, an empty
2828 address still always fails if the pattern is not itself empty.
2829
d8ef3577
PH
283030. Exim went into a mad DNS loop when attempting to do a callout where the
2831 host was specified on an smtp transport, and looking it up yielded more
2832 than one IP address.
2833
5cb8cbc6
PH
283431. Re-factored the code for checking spool and log partition space into a
2835 function that finds that data and another that does the check. The former
2836 is then used to implement four new variables: $spool_space, $log_space,
2837 $spool_inodes, and $log_inodes.
2838
14702f5b
PH
283932. The RFC2047 encoding function was originally intended for short strings
2840 such as real names; it was not keeping to the 75-character limit for
2841 encoded words that the RFC imposes. It now respects the limit, and
2842 generates multiple encoded words if necessary. To be on the safe side, I
2843 have increased the buffer size for the ${rfc2047: expansion operator from
2844 1024 to 2048 bytes.
2845
063b1e99
PH
284633. It is now permitted to omit both strings after an "if" condition; if the
2847 condition is true, the result is "true". As before, when the second string
2848 is omitted, a false condition yields an empty string. This makes it less
2849 cumbersome to write custom ACL and router conditions.
2850
652e1b65
PH
285134. Failure to deliver a bounce message always caused it to be frozen, even if
2852 there was an errors_to setting on the router. The errors_to setting is now
2853 respected.
2854
6f0c9a4f
PH
285535. If an IPv6 address is given for -bh or -bhc, it is now converted to the
2856 canonical form (fully expanded) before being placed in
2857 $sender_host_address.
2858
33397d19
PH
285936. The table in the code that translates DNS record types into text (T_A to
2860 "A" for instance) was missing entries for NS and CNAME. It is just possible
2861 that this could have caused confusion if both these types were looked up
2862 for the same domain, because the text type is used as part of Exim's
2863 per-process caching. But the chance of anyone hitting this buglet seems
2864 very small.
2865
7bb56e1f
PH
286637. The dnsdb lookup has been extended in a number of ways.
2867
2868 (1) There is a new type, "zns", which walks up the domain tree until it
2869 finds some nameserver records. It should be used with care.
2870
ea3bc19b
PH
2871 (2) There is a new type, "mxh", which is like "mx" except that it returns
2872 just the host names, not the priorities.
2873
2874 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
2875 looked up. The behaviour when one of the lookups defers can be
2876 controlled by a keyword.
7bb56e1f 2877
ea3bc19b 2878 (4) It is now possible to specify the separator character for use when
7bb56e1f 2879 multiple records are returned.
33397d19 2880
0bcb2a0e
PH
288138. The dnslists ACL condition has been extended: it is now possible to supply
2882 a list of IP addresses and/or domains to be looked up in a particular DNS
2883 domain.
2884
2ac0e484
PH
288539. Added log_selector=+queue_time_overall.
2886
4e1fde53
PH
288740. When running the queue in the test harness, wait just a tad after forking a
2888 delivery process, to get repeatability of debugging output.
2889
de365ded
PH
289041. Include certificate and key file names in error message when GnuTLS fails
2891 to set them up, because the GnuTLS error message doesn't include the name
2892 of the failing file when there is a problem reading it.
2893
f05da2e8
PH
289442. Allow both -bf and -bF in the same test run.
2895
d6453af2
PH
289643. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
2897
f7b63901
PH
289844. The "Exiscan patch" is now merged into the mainline Exim source.
2899
290045. Sometimes the final signoff response after QUIT could fail to get
2901 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
2902 < 0 before doing a fflush(). This bug looks as though it goes back to the
2903 introduction of TLS in release 3.20, but "sometimes" must have been rare
2904 because the tests only now provoked it.
2905
a444213a
PH
290646. Reset the locale to "C" after calling embedded Perl, in case it was changed
2907 (this can affect the format of dates).
2908
0ec020ea
PH
290947. exim_tidydb, when checking for the continued existence of a message for
2910 which it has found a message-specific retry record, was not finding
2911 messages that were in split spool directories. Consequently, it was
2912 deleting retry records that should have stayed in existence.
2913
b1206957
PH
291448. Steve fixed some bugs in eximstats.
2915
291649. The SPA authentication driver was not abandoning authentication and moving
2917 on to the next authenticator when an expansion was forced to fail,
2918 contradicting the general specification for all authenticators. Instead it
2919 was generating a temporary error. It now behaves as specified.
2920
26dd5a95
PH
292150. The default ordering of permitted cipher suites for GnuTLS was pessimal
2922 (the order specifies the preference for clients). The order is now AES256,
2923 AES128, 3DES, ARCFOUR128.
2924
343b2385
PH
292551. Small patch to Sieve code - explicitly set From: when generating an
2926 autoreply.
2927
1c5466b9
PH
292852. Exim crashed if a remote delivery caused a very long error message to be
2929 recorded - for instance if somebody sent an entire SpamAssassin report back
2930 as a large number of 550 error lines. This bug was coincidentally fixed by
2931 increasing the size of one of Exim's internal buffers (big_buffer) that
2932 happened as part of the Exiscan merge. However, to be on the safe side, I
2933 have made the code more robust (and fixed the comments that describe what
2934 is going on).
2935
55ee9ee3
PH
293653. Now that there can be additional text after "Completed" in log lines (if
2937 the queue_time_overall log selector is set), a one-byte patch to exigrep
2938 was needed to allow it to recognize "Completed" as not the last thing in
2939 the line.
2940
d38f8232
PH
294154. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2942 patch that reportedly fixes this has been added. I am not expert enough to
2943 create a test for it. This is what the patch creator wrote:
2944
2945 "I found a little strange behaviour of ldap code when working with
2946 Windows 2003 AD Domain, where users was placed in more than one
2947 Organization Units. When I tried to give exim partial DN, the exit code
2948 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2949 But simultaneously result of request was absolutely normal ldap result,
2950 so I produce this patch..."
2951
3295e65b
PH
2952 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2953 REFERENCE, so I have modified the code to exclude the patch when that macro
2954 is not defined.
2955
7102e136
PH
295655. Some experimental protocols are using DNS PTR records for new purposes. The
2957 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2958 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2959 leaves it alone. Component reversal etc. now happens only for IP addresses.
ea3a6f44 2960 CAN-2005-0021

PH
296256. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
2963
c2bcbe20
PH
296457. Double the size of the debug message buffer (to 2048) so that more of very
2965 long debug lines gets shown.
2966
18ce445d
PH
296758. The exicyclog utility now does better if the number of log files to keep
2968 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
2969
1f5b4c3d
PH
297059. Two changes related to the smtp_active_hostname option:
2971
2972 (1) $smtp_active_hostname is now available as a variable.
2973 (2) The default for smtp_banner uses $smtp_active_hostname instead
2974 of $primary_hostname.
2975
b975ba52
PH
297660. The host_aton() function is supposed to be passed a string that is known
2977 to be a valid IP address. However, in the case of IPv6 addresses, it was
2978 not checking this. This is a hostage to fortune. Exim now panics and dies
2979 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2980 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2981 components; fortuitously, this particular loophole had already been fixed
2982 by change 4.50/55 above.
2983
2984 If there are any other similar loopholes, the new check in host_aton()
2985 itself should stop them being exploited. The report I received stated that
2986 data on the command line could provoke the exploit when Exim was running as
2987 exim, but did not say which command line option was involved. All I could
2988 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2989 running as the user.
ea3a6f44 2990 CAN-2005-0021
85b87bc2
PH
2991
299261. There was a buffer overflow vulnerability in the SPA authentication code
2993 (which came originally from the Samba project). I have added a test to the
2994 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 2995 CAN-2005-0022
b975ba52 2996
17ffcae7
PH
299762. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
2998 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
2999
d95f9fdb
PH
300063. The daemon start-up calls getloadavg() while still root for those OS that
3001 need the first call to be done as root, but it missed one case: when
3002 deliver_queue_load_max is set with deliver_drop_privilege. This is
3003 necessary for the benefit of the queue runner, because there is no re-exec
3004 when deliver_drop_privilege is set.
3005
86b8287f
PH
300664. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3007 This has been fixed.
3008
60dc5e56
PH
300965. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3010 was in use, was not putting the data itself into the right store pool;
3011 consequently, it could be overwritten for a subsequent message in the same
3012 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3013 the caching.)
3014
533244af
PH
301566. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3016
a5a28604
PH
301767. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3018 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3019 the function were treating the return as a boolean value, which happened to
3020 work because 0=false and not-0=true, but is not correct code.
3021
7e634d24
PH
302268. The host_aton() function was not handling scoped IPv6 addresses (those
3023 with, for example, "%eth0" on the end) correctly.
3024
3e11c26b
PH
302569. Fixed some compiler warnings in acl.c for the bitmaps specified with
3026 negated items (that is, ~something) in unsigned ints. Some compilers
3027 apparently mutter when there is no cast.
3028
6729cf78
PH
302970. If an address verification called from an ACL failed, and did not produce a
3030 user-specific message (i.e. there was only a "system" message), nothing was
3031 put in $acl_verify_message. In this situation, it now puts the system
3032 message there.
3033
00f00ca5
PH
303471. Change 4.23/11 added synchronization checking at the start of an SMTP
3035 session; change 4.31/43 added the unwanted input to the log line - except
3036 that it did not do this in the start of session case. It now does.
3037
c9bdd01c
PH
303872. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3039 This is wrong and can cause the other end to generate a synchronization
3040 error if it is another Exim or anything else that does the synchronization
3041 check. A QUIT command is no longer sent after a timeout.
3042
d43194df
PH
304373. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3044 during host lookups.
3045
fe5b5d0b
PH
304674. The defer_ok option of callout verification was not working if it was used
3047 when verifying addresses in header lines, that is, for this case:
3048
3049 verify = header_sender/callout=defer_ok
3050
76a2d7ba
PH
305175. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3052 those file descriptors could be used for SMTP connections. If anything
3053 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3054 could be sent to the SMTP client, causing chaos. The daemon now opens
3055 stdin, stdout, and stderr to /dev/null when it puts itself into the
3056 background.
3057
305876. Arrange for output from Perl's "warn" command to be written to Exim's main
3059 log by default. The user can override this with suitable Perl magic.
3060
04f7d5b9
PH
306177. The use of log_message on a "discard" ACL verb, which is supposed to add to
3062 the log message when discard triggers, was not working for the DATA ACL or
3063 for the non-SMTP ACL.
3064
bc60667e
PH
306578. Error message wording change in sieve.c.
3066
bb6e88ff
PH
306779. If smtp_accept_max_per_host was set, the number of connections could be
3068 restricted to fewer than expected, because the daemon was trying to set up
3069 a new connection before checking whether the processes handling previous
3070 connections had finished. The check for completed processes is now done
3071 earlier. On busy systems, this bug wouldn't be noticed because something
3072 else would have woken the daemon, and it would have reaped the completed
3073 process earlier.
3074
1e70f85b
PH
307580. If a message was submitted locally by a user whose login name contained one
3076 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3077 It caused a spool format error. I have fixed the spool reading code. A
3078 related problem was that the "from" clause in the Received: line became
3079 illegal because of the space(s). It is now covered by ${quote_local_part.
3080
308181. Included the latest eximstats from Steve (adds average sizes to HTML Top
3082 tables).

3095----------------------------------------------------
3096See the note above about the 4.44 and 4.50 releases.
3097----------------------------------------------------
3098
3099
3100Exim version 4.44
3101-----------------
3102
3103 1. Change 4.43/35 introduced a bug that caused file counts to be
3104 incorrectly computed when quota_filecount was set in an appendfile
3105 transport
3106
3107 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3108 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3109 place.
3110
3111 3. Give more explanation in the error message when the command for a transport
3112 filter fails to execute.
3113
3114 4. There are several places where Exim runs a non-Exim command in a
3115 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3116 was being done only for the command run by the queryprogram router. It is
3117 now done for all such subprocesses. The other cases are: ${run, transport
3118 filters, and the commands run by the lmtp and pipe transports.
3119
3120 5. Some older OS have a limit of 256 on the maximum number of file
3121 descriptors. Exim was using setrlimit() to set 1000 as a large value
3122 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3123 systems. I've change it so that if it can't get 1000, it tries for 256.
3124
3125 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3126 was an oversight, and furthermore, ever since the addition of extra
3127 controls (e.g. 4.43/32), the checks on when to allow different forms of
3128 "control" were broken. There should now be diagnostics for all cases when a
3129 control that does not make sense is encountered.
3130
3131 7. $recipients is now available in the predata ACL (oversight).
3132
3133 8. Tidy the search cache before the fork to do a delivery from a message
3134 received from the command line. Otherwise the child will trigger a lookup
3135 failure and thereby defer the delivery if it tries to use (for example) a
3136 cached ldap connection that the parent has called unbind on.
3137
3138 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3139 of $address_data from the recipient verification was clobbered by the
3140 sender verification.
3141
314210. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3143 was its contents. (It was OK if the option was not defined at all.)
3144
314511. A "Completed" log line is now written for messages that are removed from
3146 the spool by the -Mrm option.
3147
314812. $host_address is now set to the target address during the checking of
3149 ignore_target_hosts.
3150
315113. When checking ignore_target_hosts for an ipliteral router, no host name was
3152 being passed; this would have caused $sender_host_name to have been used if
3153 matching the list had actually called for a host name (not very likely,
3154 since this list is usually IP addresses). A host name is now passed as
3155 "[x.x.x.x]".
3156
315714. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3158 code that specifies a non-restarting handler (typically sigaction() in
3159 modern systems) in an attempt to fix a rare and obscure crash bug.
3160
316115. Narrowed the window for a race in the daemon that could cause it to ignore
3162 SIGCHLD signals. This is not a major problem, because they are used only to
3163 wake it up if nothing else does.
3164
316516. A malformed maildirsize file could cause Exim to calculate negative values
3166 for the mailbox size or file count. Odd effects could occur as a result.
3167 The maildirsize information is now recalculated if the size or filecount
3168 end up negative.
3169
317017. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3171 support for a long time. Removed HAVE_SYS_VFS_H.
3172
ea3a6f44 317318. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3174
317519. Allow an empty sender to be matched against a lookup in an address list.
3176 Previously the only cases considered were a regular expression, or an
3177 empty pattern.

317920. Exim went into a mad DNS lookup loop when doing a callout where the
3180 host was specified on the transport, if the DNS lookup yielded more than
3181 one IP address.

318321. The RFC2047 encoding function was originally intended for short strings
3184 such as real names; it was not keeping to the 75-character limit for
3185 encoded words that the RFC imposes. It now respects the limit, and
3186 generates multiple encoded words if necessary. To be on the safe side, I
3187 have increased the buffer size for the ${rfc2047: expansion operator from
3188 1024 to 2048 bytes.

319022. Failure to deliver a bounce message always caused it to be frozen, even if
3191 there was an errors_to setting on the router. The errors_to setting is now
3192 respected.

3195 canonical form (fully expanded) before being placed in

320025. Include certificate and key file names in error message when GnuTLS fails
3201 to set them up, because the GnuTLS error message doesn't include the name
3202 of the failing file when there is a problem reading it.

321028. exim_tidydb, when checking for the continued existence of a message for
3211 which it has found a message-specific retry record, was not finding
3212 messages that were in split spool directories. Consequently, it was
3213 deleting retry records that should have stayed in existence.

321930. The SPA authentication driver was not abandoning authentication and moving
3220 on to the next authenticator when an expansion was forced to fail,
3221 contradicting the general specification for all authenticators. Instead it
3222 was generating a temporary error. It now behaves as specified.

323132. Exim crashed if a remote delivery caused a very long error message to be
3232 recorded - for instance if somebody sent an entire SpamAssassin report back
3233 as a large number of 550 error lines. This bug was coincidentally fixed by
3234 increasing the size of one of Exim's internal buffers (big_buffer) that
3235 happened as part of the Exiscan merge. However, to be on the safe side, I
3236 have made the code more robust (and fixed the comments that describe what
3237 is going on).

323933. Some experimental protocols are using DNS PTR records for new purposes. The
3240 keys for these records are domain names, not reversed IP addresses. The
3241 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3242 leaves it alone. Component reversal etc. now happens only for IP addresses.

324534. The host_aton() function is supposed to be passed a string that is known
3246 to be a valid IP address. However, in the case of IPv6 addresses, it was
3247 not checking this. This is a hostage to fortune. Exim now panics and dies
3248 if the condition is not met. A case was found where this could be provoked
3249 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3250 components; fortuitously, this particular loophole had already been fixed
3251 by change 4.50/55 or 4.44/33 above.
3252
3253 If there are any other similar loopholes, the new check in host_aton()
3254 itself should stop them being exploited. The report I received stated that
3255 data on the command line could provoke the exploit when Exim was running as
3256 exim, but did not say which command line option was involved. All I could
3257 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3258 running as the user.

326135. There was a buffer overflow vulnerability in the SPA authentication code

326636. The daemon start-up calls getloadavg() while still root for those OS that
3267 need the first call to be done as root, but it missed one case: when
3268 deliver_queue_load_max is set with deliver_drop_privilege. This is
3269 necessary for the benefit of the queue runner, because there is no re-exec
3270 when deliver_drop_privilege is set.

327237. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3273 was in use, was not putting the data itself into the right store pool;
3274 consequently, it could be overwritten for a subsequent message in the same
3275 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3276 the caching.)

3279 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3280 < 0 before doing a fflush(). This bug looks as though it goes back to the
3281 introduction of TLS in release 3.20, but "sometimes" must have been rare
3282 because the tests only now provoked it.

3285Exim version 4.43
3286-----------------
3287
3288 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3289 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3290 Now it returns an integer. A number of calls were still expecting a T/F
3291 return. Fortuitously, in all cases, the tests worked in OK situations,
3292 which is the norm. However, things would have gone wrong on any write
3293 failures on the smtp file descriptor. This function is used when sending
3294 messages over SMTP and also when doing verify callouts.
3295
3296 2. When Exim is called to do synchronous delivery of a locally submitted
3297 message (the -odf or -odi options), it no longer closes stderr before doing
3298 the delivery.
3299
3300 3. Implemented the mua_wrapper option.
3301
3302 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3303
3304 5. Implemented the functions header_remove(), header_testname(),
3305 header_add_at_position(), and receive_remove_recipient(), and exported them
3306 to local_scan().
3307
3308 6. If an ACL "warn" statement specified the addition of headers, Exim already
3309 inserted X-ACL-Warn: at the start if there was no header name. However, it
3310 was not making this test for the second and subsequent header lines if
3311 there were newlines in the string. This meant that an invalid header could
3312 be inserted if Exim was badly configured.
3313
3314 7. Allow an ACL "warn" statement to add header lines at the start or after all
3315 the Received: headers, as well as at the end.
3316
3317 8. Added the rcpt_4xx retry error code.
3318
3319 9. Added postmaster_mailfrom=xxx to callout verification option.
3320
332110. Added mailfrom=xxxx to the callout verification option, for verify=
3322 header_sender only.
3323
332411. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3325 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3326
332712. Inserted some casts to stop certain compilers warning when using pointer
3328 differences as field lengths or precisions in printf-type calls (mostly
3329 affecting debugging statements).
3330
333113. Added optional readline() support for -be (dynamically loaded).
3332
333314. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3334 same clock tick as a message's arrival, so that its received time was the
3335 same as the "first fail" time on the retry record, and that message
3336 remained on the queue past the ultimate address timeout, every queue runner
3337 would try a delivery (because it was past the ultimate address timeout) but
3338 after another failure, the ultimate address timeout, which should have then
3339 bounced the address, did not kick in. This was a "< instead of <=" error;
3340 in most cases the first failure would have been in the next clock tick
3341 after the received time, and all would be well.
3342
334315. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3344 being recognized when the domain list was tested by the match_domain
3345 condition in an expansion string.
3346
334716. Added the ${str2b64: operator.
3348
334917. Exim was always calling setrlimit() to set a large limit for the number of
3350 processes, without checking whether the existing limit was already
3351 adequate. (It did check for the limit on file descriptors.) Furthermore,
3352 errors from getrlimit() and setrlimit() were being ignored. Now they are
3353 logged to the main and panic logs, but Exim does carry on, to try to do its
3354 job under whatever limits there are.
3355
335618. Imported PCRE 5.0.
3357
335819. Trivial typo in log message " temporarily refused connection" (the leading
3359 space).
3360
336120. If the log selector return_path_on_delivery was set and an address was
3362 redirected to /dev/null, the delivery process crashed because it assumed
3363 that a return path would always be set for a "successful" delivery. In this
3364 case, the whole delivery is bypassed as an optimization, and therefore no
3365 return path is set.
3366
336721. Internal re-arrangement: the function for sending a challenge and reading
3368 a response while authentication was assuming a zero-terminated challenge
3369 string. It's now changed to take a pointer and a length, to allow for
3370 binary data in such strings.
3371
337222. Added the cyrus_sasl authenticator (code supplied by MBM).
3373
337423. Exim was not respecting finduser_retries when seeking the login of the
3375 uid under which it was called; it was always trying 10 times. (The default
3376 setting of finduser_retries is zero.) Also, it was sleeping after the final
3377 failure, which is pointless.
3378
337924. Implemented tls_on_connect_ports.
3380
338125. Implemented acl_smtp_predata.
3382
338326. If the domain in control=submission is set empty, Exim assumes that the
3384 authenticated id is a complete email address when it generates From: or
3385 Sender: header lines.
3386
338727. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3388 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3389 chown and chgrp in /bin and hostname in /usr/bin.
3390
339128. Exim was keeping the "process log" file open after each use, just as it
3392 does for the main log. This opens the possibility of it remaining open for
3393 long periods when the USR1 signal hits a daemon. Occasional processlog
3394 errors were reported, that could have been caused by this. Anyway, it seems
3395 much more sensible not to leave this file open at all, so that is what now
3396 happens.
3397
339829. The long-running daemon process does not normally write to the log once it
3399 has entered its main loop, and it closes the log before doing so. This is
3400 so that log files can straightforwardly be renamed and moved. However,
3401 there are a couple of unusual error situations where the daemon does write
3402 log entries, and I had neglected to close the log afterwards.
3403
340430. The text of an SMTP error response that was received during a remote
3405 delivery was being truncated at 512 bytes. This is too short for some of
3406 the long messages that one sometimes sees. I've increased the limit to
3407 1024.
3408
340931. It is now possible to make retry rules that apply only when a message has a
3410 specific sender, in particular, an empty sender.
3411
341232. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3413 it possible to be selective about when SMTP synchronization is enforced.
3414
341533. Added "control = caseful_local_part" and "control = "caselower_local_part".
3416
341732. Implemented hosts_connection_nolog.
3418
341933. Added an ACL for QUIT.
3420
342134. Setting "delay_warning=" to disable warnings was not working; it gave a
3422 syntax error.
3423
342435. Added mailbox_size and mailbox_filecount to appendfile.
3425
342636. Added control = no_multiline_responses to ACLs.
3427
342837. There was a bug in the logic of the code that waits for th
