TF
55TF/03 Make the exiwhat support code safe for signals. Previously Exim might
56 lock up or crash if it happened to be inside a call to libc when it
57 got a SIGUSR1 from exiwhat.
58
59 The SIGUSR1 handler appends the current process status to the process
60 log which is later printed by exiwhat. It used to use the general
61 purpose logging code to do this, but several functions it calls are
62 not safe for signals.
63
64 The new output code in the SIGUSR1 handler is specific to the process
65 log, and simple enough that it's easy to inspect for signal safety.
66 Removing some special cases also simplifies the general logging code.
67 Removing the spurious timestamps from the process log simplifies
68 exiwhat.

TF
70TF/04 Improved ratelimit ACL condition.
71
72 The /noupdate option has been deprecated in favour of /readonly which
73 has clearer semantics. The /leaky, /strict, and /readonly update modes
74 are mutually exclusive. The update mode is no longer included in the
75 database key; it just determines when the database is updated. (This
76 means that when you upgrde Exim will forget old rate measurements.)
77
78 Exim now checks that the per_* options are used with an update mode that
79 makes sense for the current ACL. For example, when Exim is processing a
80 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
81 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
82 must specify per_mail/readonly. If you omit the update mode it defaults to
83 /leaky where that makes sense (as before) or /readonly where required.
84
85 The /noupdate option is now undocumented but still supported for
86 backwards compatibility. It is equivalent to /readonly except that in
87 ACLs where /readonly is required you may specify /leaky/noupdate or
88 /strict/noupdate which are treated the same as /readonly.
89
90 A useful new feature is the /count= option. This is a generalization
91 of the per_byte option, so that you can measure the throughput of other
92 aggregate values. For example, the per_byte option is now equivalent
93 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
94
95 The per_rcpt option has been generalized using the /count= mechanism
96 (though it's more complicated than the per_byte equivalence). When it is
97 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
98 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
99 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
100 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
101 Note that using per_rcpt with a non-readonly update mode in more than
102 one ACL will cause the recipients to be double-counted. (The per_mail
103 and per_byte options don't have this problem.)
104
105 The handling of very low rates has changed slightly. If the computed rate
106 is less than the event's count (usually one) then this event is the first
107 after a long gap. In this case the rate is set to the same as this event's
108 count, so that the first message of a spam run is counted properly.
109
110 The major new feature is a mechanism for counting the rate of unique
111 events. The new per_addr option counts the number of different
112 recipients that someone has sent messages to in the last time period. It
113 behaves like per_rcpt if all the recipient addresses are different, but
114 duplicate recipient addresses do not increase the measured rate. Like
115 the /count= option this is a general mechanism, so the per_addr option
116 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
117 example, measure the rate that a client uses different sender addresses
118 with the options per_mail/unique=$sender_address. There are further
119 details in the main documentation.

691PH/01 Another patch from the Sieve maintainer.
692
6a3bceb1
PH
693PH/02 When an IPv6 address is converted to a string for single-key lookup
694 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
695 dots are used instead of colons so that keys in lsearch files need not
696 contain colons. This was done some time before quoting was made available
697 in lsearch files. However, iplsearch files do require colons in IPv6 keys
698 (notated using the quote facility) so as to distinguish them from IPv4
699 keys. This meant that lookups for IP addresses in host lists did not work
700 for iplsearch lookups.
701
702 This has been fixed by arranging for IPv6 addresses to be expressed with
703 colons if the lookup type is iplsearch. This is not incompatible, because
704 previously such lookups could never work.
705
706 The situation is now rather anomolous, since one *can* have colons in
707 ordinary lsearch keys. However, making the change in all cases is
708 incompatible and would probably break a number of configurations.

713MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
714 conversion specification without a maximum field width, thereby enabling
715 a rogue spamd server to cause a buffer overflow. While nobody in their
716 right mind would setup Exim to query an untrusted spamd server, an
717 attacker that gains access to a server running spamd could potentially
718 exploit this vulnerability to run arbitrary code as the Exim user.

MH
723MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
724 a directory entry by the name of the lookup key. Previously, if a
725 symlink pointed to a non-existing file or a file in a directory that
726 Exim lacked permissions to read, a lookup for a key matching that
727 symlink would fail. Now it is enough that a matching directory entry
728 exists, symlink or not. (Bugzilla 503.)

911PH/29 SMTP synchronization checks are implemented when a command is read -
912 there is a check that no more input is waiting when there shouldn't be
913 any. However, for some commands, a delay in an ACL can mean that it is
914 some time before the response is written. In this time, more input might
915 arrive, invalidly. So now there are extra checks after an ACL has run for
916 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
917 pipelining has not been advertised.

PH
991 the response to the final '.' that terminates a message, but only in the
992 case where the client has not sent further data following the '.'
993 (unfortunately, this is allowed). However, in many cases there won't be
994 any further data because there won't be any more messages to send. A call
995 to select() can be used: if it shows that the input is "ready", there is
996 either input waiting, or the socket has been closed. An attempt to read
997 the next input character can distinguish the two cases. Previously, Exim
58eb016e 998 would have sent an OK response which the client would never have see.

1009PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1010 fixed by 4.65/MH/01 (is this a record?) are fixed:
1011
1012 (i) An empty string was always treated as zero by the numeric comparison
1013 operators. This behaviour has been restored.
1014
1015 (ii) It is documented that the numeric comparison operators always treat
1016 their arguments as decimal numbers. This was broken in that numbers
1017 starting with 0 were being interpreted as octal.
1018
1019 While fixing these problems I realized that there was another issue that
1020 hadn't been noticed. Values of message_size_limit (both the global option
1021 and the transport option) were treated as octal if they started with 0.
1022 The documentation was vague. These values are now always treated as
1023 decimal, and I will make that clear in the documentation.

1039 is held in a short int, deliveries were likely to be lost. As such a
1040 large number of recipients for a single message is ridiculous
1041 (performance will be very, very poor), I have chosen to impose a limit
1042 rather than extend the field.

2b1c6e3a
PH
1067PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1068 callout verification, Exim cached a "reject" for the entire domain. This
1069 is correct for most verifications, but it is not correct for a recipient
1070 verification with use_sender or use_postmaster set, because in that case
1071 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1072 case of MAIL FROM:<> rejection from other early rejections (e.g.
1073 rejection of HELO). When verifying a recipient using a non-null MAIL
1074 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1075 Whatever the result of the callout, the value of the domain cache is
1076 left unchanged (for any other kind of callout, getting as far as trying
1077 RCPT means that the domain itself is ok).

1111PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1113 probably the interface on which it is arriving) and not to the outgoing
1114 callout (which could be using a different interface). This has been
1115 changed to use the value of the helo_data option from the smtp transport
1116 instead - this is what is used when a message is actually being sent. If
1117 there is no remote transport (possible with a router that sets up host
1118 addresses), $smtp_active_hostname is used.

7befa435 1121 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1122 (a) The code assumed that strncpy() returns a negative number on buffer
1123 overflow, which isn't the case. Replaced with Exim's string_format()
1124 function.
1125 (b) There were several signed/unsigned issues. I just did the minimum
1126 hacking in of casts. There is scope for a larger refactoring.
1127 (c) The code used strcasecmp() which is not a standard C function.
1128 Replaced with Exim's strcmpic() function.
1129 (d) The code set only $1; it now sets $auth1 as well.
1130 (e) A simple test gave the error "authentication client didn't specify
1131 service in request". It would seem that Dovecot has changed its
1132 interface. Fortunately there's a specification; I followed it and
1133 changed what the client sends and it appears to be working now.

1139 address A is aliased to B and C, where B exists and C does not. Without
1140 -v the output is "A verified" because verification stops after a
1141 successful redirection if more than one address is generated. However,
1142 with -v the child addresses are also verified. Exim was outputting "A
1143 failed to verify" and then showing the successful verification for C,
1144 with its parentage. It now outputs "B failed to verify", showing B's
1145 parentage before showing the successful verification of C.

322050c2
PH
1151PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1152 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1153 they consult the DNS. I had assumed they would set it the way they
1154 wanted; and indeed my experiments on Linux seem to show that in some
1155 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1156 To be on the safe side, however, I have now made the interface to
1157 host_find_byname() similar to host_find_bydns(), with an argument
1158 containing the DNS resolver options. The host_find_byname() function now
1159 sets these options at its start, just as host_find_bydns() does. The smtp
1160 transport options dns_qualify_single and dns_search_parents are passed to
1161 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1162 of host_find_byname() use the default settings of RES_DEFNAMES
1163 (qualify_single) but not RES_DNSRCH (search_parents).

1166 spool_read_header() do less string testing, by means of a preliminary
1167 switch on the second character of optional "-foo" lines. (This is
1168 overdue, caused by the large number of possibilities that now exist.
1169 Originally there were few.) While I was there, I also converted the
1170 str(n)cmp tests so they don't re-test the leading "-" and the first
1171 character, in the hope this might squeeze out yet more improvement.

1173PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1174 flag allowing group syntax was set by the header_syntax check but not
1175 turned off, possible causing trouble later; (2) The flag was not being
1176 set at all for the header_verify test, causing "group"-style headers to
1177 be rejected. I have now set it in this case, and also caused header_
1178 verify to ignore an empty address taken from a group. While doing this, I
1179 came across some other cases where the code for allowing group syntax
1180 while scanning a header line wasn't quite right (mostly, not resetting
1181 the flag correctly in the right place). These bugs could have caused
1182 trouble for malformed header lines. I hope it is now all correct.

PH
1184PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1188 code for some other use. I have removed all the tests.

PH
1190PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1191 feature that was used to support insecure browsers during the U.S. crypto
1192 embargo. It requires special client support, and Exim is probably the
1193 only MTA that supported it -- and would never use it because real RSA is

1198PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1199 authenticator to fail if there's a tab character in the incoming data
1200 (there should never be unless someone is messing about, as it's supposed
1201 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1202 if the connection is using TLS or if the remote IP is the same as the
1203 local IP, and the "valid-client-cert option" if a client certificate has
1204 been verified.

1235
1236PH/30 Exim was sometimes attempting to deliver messages that had suffered
1237 address errors (4xx response to RCPT) over the same connection as other
1238 messages routed to the same hosts. Such deliveries are always "forced",
1239 so retry times are not inspected. This resulted in far too many retries
1240 for the affected addresses. The effect occurred only when there were more
1241 hosts than the hosts_max_try setting in the smtp transport when it had
1242 the 4xx errors. Those hosts that it had tried were not added to the list
1243 of hosts for which the message was waiting, so if all were tried, there
1244 was no problem. Two fixes have been applied:
1245
1246 (i) If there are any address or message errors in an SMTP delivery, none
1247 of the hosts (tried or untried) are now added to the list of hosts
1248 for which the message is waiting, so the message should not be a
1249 candidate for sending over the same connection that was used for a
1250 successful delivery of some other message. This seems entirely
1251 reasonable: after all the message is NOT "waiting for some host".
1252 This is so "obvious" that I'm not sure why it wasn't done
1253 previously. Hope I haven't missed anything, but it can't do any
1254 harm, as the worst effect is to miss an optimization.
1255
1256 (ii) If, despite (i), such a delivery is accidentally attempted, the
1257 routing retry time is respected, so at least it doesn't keep
1258 hammering the server.

PH
1273PH/35 The error "getsockname() failed: connection reset by peer" was being
1274 written to the panic log as well as the main log, but it isn't really
1275 panic-worthy as it just means the connection died rather early on. I have
1276 removed the panic log writing for the ECONNRESET error when getsockname()
1277 fails.
1278
48c7f9e2
PH
1279PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1280 runs only) independently of the message's sender address. This meant
1281 that, if the 4xx error was in fact related to the sender, a different
1282 message to the same recipient with a different sender could confuse
1283 things. In particualar, this can happen when sending to a greylisting
1284 server, but other circumstances could also provoke similar problems.
1285 I have changed the default so that the retry time for these errors is now
1286 based a combination of the sender and recipient addresses. This change
1287 can be overridden by setting address_retry_include_sender=false in the
1288 smtp transport.

1561 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1562 554 error is used if errno is still zero or contains ENOENT (which occurs

1586PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1587 folder from quota calculations, a direct delivery into this folder messed
1588 up the contents of the maildirsize file. This was because the regex was
1589 used only to exclude .Trash (or whatever) when the size of the mailbox
1590 was calculated. There was no check that a delivery was happening into an
1591 excluded directory. This bug has been fixed by ignoring all quota
1592 processing for deliveries into excluded directories.

1600PH/01 The code for finding all the local interface addresses on a FreeBSD
1601 system running IPv6 was broken. This may well have applied to all BSD
1602 systems, as well as to others that have similar system calls. The broken
1603 code found IPv4 interfaces correctly, but gave incorrect values for the
1604 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1605 that it would not match correctly against @[] and not recognize the IPv6
1606 addresses as local.

1649 autoreply, Exim could try to deliver to a non-existent relative file

1651 it logs this as a hard delivery error, but does not attempt to create a

1669 non-existent - all you got was a failure to exec. I have made two
1670 changes:
1671
1672 (a) Failures to set uid/gid, the current directory, or a process leader
1673 in a subprocess such as that created by queryprogram now generate
1674 suitable debugging ouput when -d is set.
1675

1678 the subprocess without attempting to change uid/gid.

1683PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1684 additional section of a DNS packet that returns MX or SRV records.
1685 Instead, it always explicitly searches for A/AAAA records. This avoids
1686 major problems that occur when a DNS server includes only records of one
1687 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1688 fixed another bug: if SRV records were looked up and the corresponding
1689 address records were *not* found in the additional section, the port
1690 values from the SRV records were lost.

PH
1700PH/19 When calculating a retry time, Exim used to measure the "time since
1701 failure" by looking at the "first failed" field in the retry record. Now
1702 it does not use this if it is later than than the arrival time of the
1703 message. Instead it uses the arrival time. This makes for better
1704 behaviour in cases where some deliveries succeed, thus re-setting the
1705 "first failed" field. An example is a quota failure for a huge message
1706 when small messages continue to be delivered. Without this change, the
1707 "time since failure" will always be short, possible causing more frequent
1708 delivery attempts for the huge message than are intended.

PH
1805PH/42 The content-scanning code uses fopen() to create files in which to put
1806 message data. Previously it was not paying any attention to the mode of
1807 the files. Exim runs with umask(0) because the rest of the code creates
1808 files with open(), and sets the required mode explicitly. Thus, these
1809 files were ending up world-writeable. This was not a big issue, because,
1810 being within the spool directory, they were not world-accessible. I have
1811 created a function called modefopen, which takes an additional mode
1812 argument. It sets umask(777), creates the file, chmods it to the required
1813 mode, then resets the umask. All the relevant calls to fopen() in the
1814 content scanning code have been changed to use this function.

1826 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

1851
1852 (i) Exim was not creating retry information for temporary errors given
1853 for individual recipients after the DATA command when the smtp transport
1854 was used in LMTP mode. This meant that they could be retried too
1855 frequently, and not timed out correctly.
1856
1857 (ii) Exim was setting the flag that allows error details to be returned
1858 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1859 recipients that were returned after the DATA command.
1860
1861PH/53 This is related to PH/52, but is more general: for any failing address,
1862 when detailed error information was permitted to be returned to the

1935PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1936 function verify_get_ident() calls ip_connect() to connect a socket, but
1937 if the "connect()" function timed out, ip_connect() used to close the
1938 socket. However, verify_get_ident() also closes the socket later, and in
1939 between Exim writes to the log, which may get opened at this point. When
1940 the socket was closed in ip_connect(), the log could get the same file
1941 descriptor number as the socket. This naturally causes chaos. The fix is
1942 not to close the socket in ip_connect(); the socket should be closed by
1943 the function that creates it. There was only one place in the code where
1944 this was missing, in the iplookup router, which I don't think anybody now
1945 uses, but I've fixed it anyway.

2002 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2003 not being looked up in the rDNS to get a host name, Exim was showing the
2004 IP address twice in Received: lines, even though the IP addresses were
2005 identical. For example:
2006
2007 Received: from [1.2.3.4] (helo=[1.2.3.4])
2008
2009 However, if the real host name was known, it was omitting the HELO data

2011 doesn't show the same IP address twice.

2043 warnings). In the case of bounce messages for non-SMTP mesages, there was
2044 also a typo: it was using "Auto_submitted" (underscore instead of
2045 hyphen). Since every message generated by Exim is necessarily in response
2046 to another message, thes have all been changed to:
2047
2048 Auto-Submitted: auto-replied

2100PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2102 the IP address, check_host() was doing a simple string comparison with
2103 addresses acquired from the DNS when checking that the found name did
2104 have the original IP as one of its addresses. Since any found IPv6
2105 addresses are likely to be in abbreviated form, the comparison could
2106 fail. Luckily, there already exists a function for doing the comparison
2107 by converting both addresses to binary, so now that is used instead of
2108 the text comparison.

2405PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2406 with the definition in sysexits.h (which is #included earlier).
2407 Fortunately, Exim does not actually use EX_OK. The code used to try to
2408 preserve the sysexits.h value, by assumimg that macro definitions were
2409 scanned for macro replacements. I have been disabused of this notion,
2410 so now the code just undefines EX_OK before #including unistd.h.

2412PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout

2415 This seems wrong - if the receiver was accepting one byte at a time it
2416 would take for ever. The timeout is now adjusted when this happens. It
2417 doesn't have to be particularly precise.

2626PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2627 that changes the way the GnuTLS parameters are stored in the cache file.
2628 The new format can be generated externally. For backward compatibility,
2629 if the data in the cache doesn't make sense, Exim assumes it has read an
2630 old-format file, and it generates new data and writes a new file. This
2631 means that you can't go back to an older release without removing the
2632 file.
2633
2634PH/03 A redirect router that has both "unseen" and "one_time" set does not
2635 work if there are any delivery delays because "one_time" forces the
2636 parent to be marked "delivered", so its unseen clone is never tried
2637 again. For this reason, Exim now forbids the simultaneous setting of
2638 these two options.
2639
2640PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2641 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2642 entry if you want to know the details. The fix, however, neglected to
2643 consider the case when local delivery batching is involved. The test for
2644 "previously delivered" was not happening when checking to see if an
2645 address could be batched with a previous (undelivered) one; under
2646 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2647 address.

2649PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2652PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2653 header_syntax) but Exim was just ignoring anything given after a slash.
2654 In particular, this caused confusion with an attempt to use "verify =
2655 reverse_host_lookup/defer_ok". An error is now given when options are
2656 supplied for verify items that do not have them. (Maybe reverse_host_
2657 lookup should have a defer_ok option, but that's a different point.)
2658
2659PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2712 the file with the wrong ownership). There was no test for failure of this
2713 fork() call, which would lead to the process getting stuck as it waited
2714 for a non-existent subprocess. Forks do occasionally fail when resources

2735PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2736 hadn't been configured. The fix is from Juergen Kreileder, who
2737 understands it better than I do:
2738
2739 "Here's what I see happening with three configured cyrus_sasl
2740 authenticators configured (plain, login, cram-md5):
2741
2742 On startup auth_cyrus_sasl_init() gets called for each of these.
2743 This means three calls to sasl_listmech() without a specified mech_list.
2744 => SASL tests which mechs of all available mechs actually work
2745 => three warnings about OTP not working
2746 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2747
2748 With the patch, sasl_listmech() also gets called three times. But now
2749 SASL's mech_list option is set to the server_mech specified in the the
2750 authenticator. Or in other words, the answer from sasl_listmech()
2751 gets limited to just the mech you're testing for (which is different
2752 for each call.)
2753 => the return list contains just 'plain' or 'login', 'cram-md5' or
2754 nothing depending on the value of ob->server_mech.
2755

2789PH/30 In these circumstances:
2790 . Two addresses routed to the same list of hosts;
2791 . First host does not offer TLS;
2792 . First host accepts first address;
2793 . First host gives temporary error to second address;
2794 . Second host offers TLS and a TLS session is established;
2795 . Second host accepts second address.
2796 Exim incorrectly logged both deliveries with the TLS parameters (cipher
2797 and peerdn, if requested) that were in fact used only for the second
2798 address.

2800PH/31 When doing a callout as part of verifying an address, Exim was not paying
2801 attention to any local part prefix or suffix that was matched by the

2803 does for delivery: the affixes are removed from the local part unless

PH
2822PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2823 the grounds that routing the same address twice would always produce the
2824 same answer. This might have been true once, but it is certainly no
2825 longer true now. Routing a child address may depend on the previous
2826 routing that produced that child. Some complicated redirection strategies
2827 went wrong when messages had multiple recipients, and made Exim's
2828 behaviour dependent on the order in which the addresses were given.
2829
2830 I have moved the duplicate checking until after the routing is complete.
2831 Exim scans the addresses that are assigned to local and remote
2832 transports, and removes any duplicates. This means that more work will be
2833 done, as duplicates will always all be routed, but duplicates are
2834 presumably rare, so I don't expect this is of any significance.
2835
2836 For deliveries to pipes, files, and autoreplies, the duplicate checking
2837 still happens during the routing process, since they are not going to be
2838 routed further.

2843 connection it has accepted, or it never writes response data. The exiscan
2844 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2845 blindly assumes that writes won't block so it may never time out."

2860 bounce and delay warning messages, except in certain special cases, which
2861 are as follows:

2863 (a) An SMTP error message from a remote host;
2864 (b) A message specified in a :fail: redirection;
2865 (c) A message specified in a "fail" command in a system filter;
2866 (d) A message specified in a FAIL return from the queryprogram router;
2867 (e) A message specified by the cannot_route_message router option.
2868
2869 In these cases only, Exim does include the error details in bounce and
2870 warning messages. There are also a few cases where bland messages such
2871 as "unrouteable address" or "local delivery error" are given.

2879PH/45 In a pipe transport, although a timeout while waiting for the pipe
2880 process to complete was treated as a delivery failure, a timeout while
2881 writing the message to the pipe was logged, but erroneously treated as a
2882 successful delivery. Such timeouts include transport filter timeouts. For
2883 consistency with the overall process timeout, these timeouts are now
2884 treated as errors, giving rise to delivery failures by default. However,
2885 there is now a new Boolean option for the pipe transport called
2886 timeout_defer, which, if set TRUE, converts the failures into defers for
2887 both kinds of timeout. A transport filter timeout is now identified in
2888 the log output.

2897A note about Exim versions 4.44 and 4.50
2898----------------------------------------
2899
2900Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2901changes of various kinds. As a consequence, a big documentation update was
2902needed. This delayed the release for rather longer than seemed good, especially
2903in the light of a couple of (minor) security issues. Therefore, the changes
2904that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2905release. So 4.44 and 4.50 are in effect two different branches that both start
2906from 4.43.
2907
2908I have left the 4.50 change log unchanged; it contains all the changes since
29094.43. The change log for 4.44 is below; many of its items are identical to
2910those for 4.50. This seems to be the most sensible way to preserve the
2911historical information.

2917 1. Minor wording change to the doc/README.SIEVE file.

2922 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The

b668c215
PH
2929 5. There are several places where Exim runs a non-Exim command in a
2930 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2931 was being done only for the command run by the queryprogram router. It is
2932 now done for all such subprocesses. The other cases are: ${run, transport
2933 filters, and the commands run by the lmtp and pipe transports.

PH
2935 6. Added CONFIGURE_GROUP build-time option.
2936
2937 7. Some older OS have a limit of 256 on the maximum number of file
2938 descriptors. Exim was using setrlimit() to set 1000 as a large value
2939 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2940 systems. I've change it so that if it can't get 1000, it tries for 256.

2942 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2943 was an oversight, and furthermore, ever since the addition of extra
2944 controls (e.g. 4.43/32), the checks on when to allow different forms of
2945 "control" were broken. There should now be diagnostics for all cases when a
2946 control that does not make sense is encountered.

295712. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2958 of $address_data from the recipient verification was clobbered by the

298722. $host_address is now set to the target address during the checking of
2988 ignore_target_hosts.
2989
299023. When checking ignore_target_hosts for an ipliteral router, no host name was
2991 being passed; this would have caused $sender_host_name to have been used if
2992 matching the list had actually called for a host name (not very likely,
2993 since this list is usually IP addresses). A host name is now passed as
2994 "[x.x.x.x]".
2995
7d468ab8
PH
299624. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2997 code that specifies a non-restarting handler (typically sigaction() in
2998 modern systems) in an attempt to fix a rare and obscure crash bug.
2999
300025. Narrowed the window for a race in the daemon that could cause it to ignore
3001 SIGCHLD signals. This is not a major problem, because they are used only to
3002 wake it up if nothing else does.
3003
62c0818f
PH
300426. A malformed maildirsize file could cause Exim to calculate negative values
3005 for the mailbox size or file count. Odd effects could occur as a result.
3006 The maildirsize information is now recalculated if the size or filecount
3007 end up negative.
3008
26034054
PH
300927. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3010 support for a long time. Removed HAVE_SYS_VFS_H.

301228. Installed the latest version of exipick from John Jetmore.
3013
90af77f4
PH
301429. In an address list, if the pattern was not a regular expression, an empty
3015 subject address (from a bounce message) matched only if the pattern was an
3016 empty string. Non-empty patterns were not even tested. This was the wrong
3017 because it is perfectly reasonable to use an empty address as part of a
3018 database query. An empty address is now tested by patterns that are
3019 lookups. However, all the other forms of pattern expect the subject to
3020 contain a local part and a domain, and therefore, for them, an empty
3021 address still always fails if the pattern is not itself empty.
3022
d8ef3577
PH
302330. Exim went into a mad DNS loop when attempting to do a callout where the
3024 host was specified on an smtp transport, and looking it up yielded more
3025 than one IP address.
3026
5cb8cbc6
PH
302731. Re-factored the code for checking spool and log partition space into a
3028 function that finds that data and another that does the check. The former
3029 is then used to implement four new variables: $spool_space, $log_space,
3030 $spool_inodes, and $log_inodes.
3031
14702f5b
PH
303232. The RFC2047 encoding function was originally intended for short strings
3033 such as real names; it was not keeping to the 75-character limit for
3034 encoded words that the RFC imposes. It now respects the limit, and
3035 generates multiple encoded words if necessary. To be on the safe side, I
3036 have increased the buffer size for the ${rfc2047: expansion operator from
3037 1024 to 2048 bytes.
3038
063b1e99
PH
303933. It is now permitted to omit both strings after an "if" condition; if the
3040 condition is true, the result is "true". As before, when the second string
3041 is omitted, a false condition yields an empty string. This makes it less
3042 cumbersome to write custom ACL and router conditions.
3043
652e1b65
PH
304434. Failure to deliver a bounce message always caused it to be frozen, even if
3045 there was an errors_to setting on the router. The errors_to setting is now
3046 respected.
3047
6f0c9a4f
PH
304835. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3049 canonical form (fully expanded) before being placed in
3050 $sender_host_address.
3051
33397d19
PH
305236. The table in the code that translates DNS record types into text (T_A to
3053 "A" for instance) was missing entries for NS and CNAME. It is just possible
3054 that this could have caused confusion if both these types were looked up
3055 for the same domain, because the text type is used as part of Exim's
3056 per-process caching. But the chance of anyone hitting this buglet seems
3057 very small.
3058
7bb56e1f
PH
305937. The dnsdb lookup has been extended in a number of ways.
3060
3061 (1) There is a new type, "zns", which walks up the domain tree until it
3062 finds some nameserver records. It should be used with care.
3063
ea3bc19b
PH
3064 (2) There is a new type, "mxh", which is like "mx" except that it returns
3065 just the host names, not the priorities.
3066
3067 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19

3068 looked up. The behaviour when one of the lookups defers can be
3069 controlled by a keyword.
7bb56e1f 3070
ea3bc19b 3071 (4) It is now possible to specify the separator character for use when
7bb56e1f 3072 multiple records are returned.
33397d19 3073
0bcb2a0e
PH

3075 a list of IP addresses and/or domains to be looked up in a particular DNS
3076 domain.

PH
308341. Include certificate and key file names in error message when GnuTLS fails

3094 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3095 < 0 before doing a fflush(). This bug looks as though it goes back to the
3096 introduction of TLS in release 3.20, but "sometimes" must have been rare
3097 because the tests only now provoked it.

PH
312152. Exim crashed if a remote delivery caused a very long error message to be
3122 recorded - for instance if somebody sent an entire SpamAssassin report back
3123 as a large number of 550 error lines. This bug was coincidentally fixed by
3124 increasing the size of one of Exim's internal buffers (big_buffer) that
3125 happened as part of the Exiscan merge. However, to be on the safe side, I
3126 have made the code more robust (and fixed the comments that describe what
3127 is going on).

3132 the line.

PH
313454. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3135 patch that reportedly fixes this has been added. I am not expert enough to
3136 create a test for it. This is what the patch creator wrote:
3137
3138 "I found a little strange behaviour of ldap code when working with
3139 Windows 2003 AD Domain, where users was placed in more than one
3140 Organization Units. When I tried to give exim partial DN, the exit code
3141 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3142 But simultaneously result of request was absolutely normal ldap result,
3143 so I produce this patch..."
3144
3295e65b
PH
3145 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3146 REFERENCE, so I have modified the code to exclude the patch when that macro
3147 is not defined.

314955. Some experimental protocols are using DNS PTR records for new purposes. The
3150 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3151 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3152 leaves it alone. Component reversal etc. now happens only for IP addresses.

316058. The exicyclog utility now does better if the number of log files to keep

PH
316359. Two changes related to the smtp_active_hostname option:
3164
3165 (1) $smtp_active_hostname is now available as a variable.
3166 (2) The default for smtp_banner uses $smtp_active_hostname instead
3167 of $primary_hostname.

b975ba52
PH
316960. The host_aton() function is supposed to be passed a string that is known
3170 to be a valid IP address. However, in the case of IPv6 addresses, it was
3171 not checking this. This is a hostage to fortune. Exim now panics and dies
3172 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3173 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3174 components; fortuitously, this particular loophole had already been fixed
3175 by change 4.50/55 above.
3176
3177 If there are any other similar loopholes, the new check in host_aton()
3178 itself should stop them being exploited. The report I received stated that
3179 data on the command line could provoke the exploit when Exim was running as
3180 exim, but did not say which command line option was involved. All I could
3181 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3182 running as the user.

3184
318561. There was a buffer overflow vulnerability in the SPA authentication code
3186 (which came originally from the Samba project). I have added a test to the
3187 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3188 CAN-2005-0022

PH
319062. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3191 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3192
d95f9fdb
PH
319363. The daemon start-up calls getloadavg() while still root for those OS that
3194 need the first call to be done as root, but it missed one case: when
3195 deliver_queue_load_max is set with deliver_drop_privilege. This is
3196 necessary for the benefit of the queue runner, because there is no re-exec
3197 when deliver_drop_privilege is set.
3198

PH
319964. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3200 This has been fixed.
3201
60dc5e56
PH
320265. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3203 was in use, was not putting the data itself into the right store pool;
3204 consequently, it could be overwritten for a subsequent message in the same
3205 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3206 the caching.)
3207
533244af
PH
320866. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3209
a5a28604
PH
321067. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3211 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3212 the function were treating the return as a boolean value, which happened to
3213 work because 0=false and not-0=true, but is not correct code.
3214
7e634d24
PH
321568. The host_aton() function was not handling scoped IPv6 addresses (those
3216 with, for example, "%eth0" on the end) correctly.
3217
3e11c26b
PH
321869. Fixed some compiler warnings in acl.c for the bitmaps specified with
3219 negated items (that is, ~something) in unsigned ints. Some compilers
3220 apparently mutter when there is no cast.
3221
6729cf78
PH
322270. If an address verification called from an ACL failed, and did not produce a
3223 user-specific message (i.e. there was only a "system" message), nothing was
3224 put in $acl_verify_message. In this situation, it now puts the system
3225 message there.
3226
00f00ca5
PH
322771. Change 4.23/11 added synchronization checking at the start of an SMTP
3228 session; change 4.31/43 added the unwanted input to the log line - except
3229 that it did not do this in the start of session case. It now does.
3230
c9bdd01c
PH
323172. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3232 This is wrong and can cause the other end to generate a synchronization
3233 error if it is another Exim or anything else that does the synchronization
3234 check. A QUIT command is no longer sent after a timeout.
3235
d43194df
PH
323673. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3237 during host lookups.
3238

PH
323974. The defer_ok option of callout verification was not working if it was used
3240 when verifying addresses in header lines, that is, for this case:
3241
3242 verify = header_sender/callout=defer_ok
3243
76a2d7ba
PH
324475. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3245 those file descriptors could be used for SMTP connections. If anything
3246 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3247 could be sent to the SMTP client, causing chaos. The daemon now opens
3248 stdin, stdout, and stderr to /dev/null when it puts itself into the
3249 background.
3250
325176. Arrange for output from Perl's "warn" command to be written to Exim's main
3252 log by default. The user can override this with suitable Perl magic.
3253
04f7d5b9
PH
325477. The use of log_message on a "discard" ACL verb, which is supposed to add to
3255 the log message when discard triggers, was not working for the DATA ACL or
3256 for the non-SMTP ACL.
3257
bc60667e
PH
325878. Error message wording change in sieve.c.
3259
bb6e88ff
PH
326079. If smtp_accept_max_per_host was set, the number of connections could be
3261 restricted to fewer than expected, because the daemon was trying to set up
3262 a new connection before checking whether the processes handling previous
3263 connections had finished. The check for completed processes is now done
3264 earlier. On busy systems, this bug wouldn't be noticed because something
3265 else would have woken the daemon, and it would have reaped the completed
3266 process earlier.
3267
1e70f85b
PH
326880. If a message was submitted locally by a user whose login name contained one
3269 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3270 It caused a spool format error. I have fixed the spool reading code. A
3271 related problem was that the "from" clause in the Received: line became
3272 illegal because of the space(s). It is now covered by ${quote_local_part.
3273
327481. Included the latest eximstats from Steve (adds average sizes to HTML Top
3275 tables).

3288----------------------------------------------------
3289See the note above about the 4.44 and 4.50 releases.
3290----------------------------------------------------
3291
3292
3293Exim version 4.44
3294-----------------
3295
3296 1. Change 4.43/35 introduced a bug that caused file counts to be
3297 incorrectly computed when quota_filecount was set in an appendfile
3298 transport
3299
3300 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3301 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3302 place.
3303
3304 3. Give more explanation in the error message when the command for a transport
3305 filter fails to execute.
3306
3307 4. There are several places where Exim runs a non-Exim command in a
3308 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3309 was being done only for the command run by the queryprogram router. It is
3310 now done for all such subprocesses. The other cases are: ${run, transport
3311 filters, and the commands run by the lmtp and pipe transports.
3312
3313 5. Some older OS have a limit of 256 on the maximum number of file
3314 descriptors. Exim was using setrlimit() to set 1000 as a large value
3315 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3316 systems. I've change it so that if it can't get 1000, it tries for 256.
3317
3318 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3319 was an oversight, and furthermore, ever since the addition of extra
3320 controls (e.g. 4.43/32), the checks on when to allow different forms of
3321 "control" were broken. There should now be diagnostics for all cases when a
3322 control that does not make sense is encountered.
3323
3324 7. $recipients is now available in the predata ACL (oversight).
3325
3326 8. Tidy the search cache before the fork to do a delivery from a message
3327 received from the command line. Otherwise the child will trigger a lookup
3328 failure and thereby defer the delivery if it tries to use (for example) a
3329 cached ldap connection that the parent has called unbind on.
3330
3331 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3332 of $address_data from the recipient verification was clobbered by the
3333 sender verification.
3334
333510. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3336 was its contents. (It was OK if the option was not defined at all.)
3337
333811. A "Completed" log line is now written for messages that are removed from
3339 the spool by the -Mrm option.
3340
334112. $host_address is now set to the target address during the checking of
3342 ignore_target_hosts.
3343
334413. When checking ignore_target_hosts for an ipliteral router, no host name was
3345 being passed; this would have caused $sender_host_name to have been used if
3346 matching the list had actually called for a host name (not very likely,
3347 since this list is usually IP addresses). A host name is now passed as
3348 "[x.x.x.x]".
3349
335014. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3351 code that specifies a non-restarting handler (typically sigaction() in
3352 modern systems) in an attempt to fix a rare and obscure crash bug.
3353
335415. Narrowed the window for a race in the daemon that could cause it to ignore
3355 SIGCHLD signals. This is not a major problem, because they are used only to
3356 wake it up if nothing else does.
3357
335816. A malformed maildirsize file could cause Exim to calculate negative values
3359 for the mailbox size or file count. Odd effects could occur as a result.
3360 The maildirsize information is now recalculated if the size or filecount
3361 end up negative.
3362
336317. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3364 support for a long time. Removed HAVE_SYS_VFS_H.
3365
ea3a6f44 336618. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3367
336819. Allow an empty sender to be matched against a lookup in an address list.
3369 Previously the only cases considered were a regular expression, or an
3370 empty pattern.
3371
337220. Exim went into a mad DNS lookup loop when doing a callout where the
3373 host was specified on the transport, if the DNS lookup yielded more than
3374 one IP address.
3375
ea3a6f44
NM
337621. The RFC2047 encoding function was originally intended for short strings
3377 such as real names; it was not keeping to the 75-character limit for
3378 encoded words that the RFC imposes. It now respects the limit, and
3379 generates multiple encoded words if necessary. To be on the safe side, I
3380 have increased the buffer size for the ${rfc2047: expansion operator from
3381 1024 to 2048 bytes.
bbe902f0 3382
ea3a6f44
NM
338322. Failure to deliver a bounce message always caused it to be frozen, even if
3384 there was an errors_to setting on the router. The errors_to setting is now
3385 respected.
bbe902f0
PH
3386
338723. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3388 canonical form (fully expanded) before being placed in
3389 $sender_host_address.
3390
339124. Updated eximstats to version 1.33
3392
ea3a6f44
NM
339325. Include certificate and key file names in error message when GnuTLS fails
3394 to set them up, because the GnuTLS error message doesn't include the name
3395 of the failing file when there is a problem reading it.
bbe902f0
PH
3396
339726. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3398 As per change 25.
bbe902f0 3399
ea3a6f44
NM
340027. Reset the locale to "C" after calling embedded Perl, in case it was changed
3401 (this can affect the format of dates).
bbe902f0 3402
ea3a6f44
NM
340328. exim_tidydb, when checking for the continued existence of a message for
3404 which it has found a message-specific retry record, was not finding
3405 messages that were in split spool directories. Consequently, it was
3406 deleting retry records that should have stayed in existence.
bbe902f0
PH
3407
340829. eximstats updated to version 1.35
3409 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3410 1.35 - bugfix such that pie charts by volume are generated correctly
