TF
59TF/03 Make the exiwhat support code safe for signals. Previously Exim might
60 lock up or crash if it happened to be inside a call to libc when it
61 got a SIGUSR1 from exiwhat.
62
63 The SIGUSR1 handler appends the current process status to the process
64 log which is later printed by exiwhat. It used to use the general
65 purpose logging code to do this, but several functions it calls are
66 not safe for signals.
67
68 The new output code in the SIGUSR1 handler is specific to the process
69 log, and simple enough that it's easy to inspect for signal safety.
70 Removing some special cases also simplifies the general logging code.
71 Removing the spurious timestamps from the process log simplifies
72 exiwhat.
73
c99ce5c9
TF
74TF/04 Improved ratelimit ACL condition.
75
76 The /noupdate option has been deprecated in favour of /readonly which
77 has clearer semantics. The /leaky, /strict, and /readonly update modes
78 are mutually exclusive. The update mode is no longer included in the
79 database key; it just determines when the database is updated. (This
80 means that when you upgrde Exim will forget old rate measurements.)
81
82 Exim now checks that the per_* options are used with an update mode that
83 makes sense for the current ACL. For example, when Exim is processing a
84 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
85 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
86 must specify per_mail/readonly. If you omit the update mode it defaults to
87 /leaky where that makes sense (as before) or /readonly where required.
88
89 The /noupdate option is now undocumented but still supported for
90 backwards compatibility. It is equivalent to /readonly except that in
91 ACLs where /readonly is required you may specify /leaky/noupdate or
92 /strict/noupdate which are treated the same as /readonly.
93
94 A useful new feature is the /count= option. This is a generalization
95 of the per_byte option, so that you can measure the throughput of other
96 aggregate values. For example, the per_byte option is now equivalent
97 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
98
99 The per_rcpt option has been generalized using the /count= mechanism
100 (though it's more complicated than the per_byte equivalence). When it is
101 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
102 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
103 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
104 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
105 Note that using per_rcpt with a non-readonly update mode in more than
106 one ACL will cause the recipients to be double-counted. (The per_mail
107 and per_byte options don't have this problem.)
108
109 The handling of very low rates has changed slightly. If the computed rate
110 is less than the event's count (usually one) then this event is the first
111 after a long gap. In this case the rate is set to the same as this event's
112 count, so that the first message of a spam run is counted properly.
113
114 The major new feature is a mechanism for counting the rate of unique
115 events. The new per_addr option counts the number of different
116 recipients that someone has sent messages to in the last time period. It
117 behaves like per_rcpt if all the recipient addresses are different, but
118 duplicate recipient addresses do not increase the measured rate. Like
119 the /count= option this is a general mechanism, so the per_addr option
120 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
121 example, measure the rate that a client uses different sender addresses
122 with the options per_mail/unique=$sender_address. There are further
123 details in the main documentation.

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

695PH/01 Another patch from the Sieve maintainer.
696
6a3bceb1
PH
697PH/02 When an IPv6 address is converted to a string for single-key lookup
698 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
699 dots are used instead of colons so that keys in lsearch files need not
700 contain colons. This was done some time before quoting was made available
701 in lsearch files. However, iplsearch files do require colons in IPv6 keys
702 (notated using the quote facility) so as to distinguish them from IPv4
703 keys. This meant that lookups for IP addresses in host lists did not work
704 for iplsearch lookups.
705
706 This has been fixed by arranging for IPv6 addresses to be expressed with
707 colons if the lookup type is iplsearch. This is not incompatible, because
708 previously such lookups could never work.
709
710 The situation is now rather anomolous, since one *can* have colons in
711 ordinary lsearch keys. However, making the change in all cases is
712 incompatible and would probably break a number of configurations.

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

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

809 if a client was not listed at all, or was listed with a value other than
810 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

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

995 the response to the final '.' that terminates a message, but only in the
996 case where the client has not sent further data following the '.'
997 (unfortunately, this is allowed). However, in many cases there won't be
998 any further data because there won't be any more messages to send. A call
999 to select() can be used: if it shows that the input is "ready", there is
1000 either input waiting, or the socket has been closed. An attempt to read
1001 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1002 would have sent an OK response which the client would never have see.

1013PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1014 fixed by 4.65/MH/01 (is this a record?) are fixed:
1015
1016 (i) An empty string was always treated as zero by the numeric comparison
1017 operators. This behaviour has been restored.
1018
1019 (ii) It is documented that the numeric comparison operators always treat
1020 their arguments as decimal numbers. This was broken in that numbers
1021 starting with 0 were being interpreted as octal.
1022
1023 While fixing these problems I realized that there was another issue that
1024 hadn't been noticed. Values of message_size_limit (both the global option
1025 and the transport option) were treated as octal if they started with 0.
1026 The documentation was vague. These values are now always treated as
1027 decimal, and I will make that clear in the documentation.

1044 large number of recipients for a single message is ridiculous
1045 (performance will be very, very poor), I have chosen to impose a limit
1046 rather than extend the field.

2b1c6e3a
PH
1071PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1072 callout verification, Exim cached a "reject" for the entire domain. This
1073 is correct for most verifications, but it is not correct for a recipient
1074 verification with use_sender or use_postmaster set, because in that case
1075 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1076 case of MAIL FROM:<> rejection from other early rejections (e.g.
1077 rejection of HELO). When verifying a recipient using a non-null MAIL
1078 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1079 Whatever the result of the callout, the value of the domain cache is
1080 left unchanged (for any other kind of callout, getting as far as trying
1081 RCPT means that the domain itself is ok).

1115PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1117 probably the interface on which it is arriving) and not to the outgoing
1118 callout (which could be using a different interface). This has been
1119 changed to use the value of the helo_data option from the smtp transport
1120 instead - this is what is used when a message is actually being sent. If
1121 there is no remote transport (possible with a router that sets up host
1122 addresses), $smtp_active_hostname is used.

7befa435 1125 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1126 (a) The code assumed that strncpy() returns a negative number on buffer
1127 overflow, which isn't the case. Replaced with Exim's string_format()
1128 function.
1129 (b) There were several signed/unsigned issues. I just did the minimum
1130 hacking in of casts. There is scope for a larger refactoring.
1131 (c) The code used strcasecmp() which is not a standard C function.
1132 Replaced with Exim's strcmpic() function.
1133 (d) The code set only $1; it now sets $auth1 as well.
1134 (e) A simple test gave the error "authentication client didn't specify
1135 service in request". It would seem that Dovecot has changed its
1136 interface. Fortunately there's a specification; I followed it and
1137 changed what the client sends and it appears to be working now.

1143 address A is aliased to B and C, where B exists and C does not. Without
1144 -v the output is "A verified" because verification stops after a
1145 successful redirection if more than one address is generated. However,
1146 with -v the child addresses are also verified. Exim was outputting "A
1147 failed to verify" and then showing the successful verification for C,
1148 with its parentage. It now outputs "B failed to verify", showing B's
1149 parentage before showing the successful verification of C.

1154
322050c2
PH
1155PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1156 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1157 they consult the DNS. I had assumed they would set it the way they
1158 wanted; and indeed my experiments on Linux seem to show that in some
1159 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1160 To be on the safe side, however, I have now made the interface to
1161 host_find_byname() similar to host_find_bydns(), with an argument
1162 containing the DNS resolver options. The host_find_byname() function now
1163 sets these options at its start, just as host_find_bydns() does. The smtp
1164 transport options dns_qualify_single and dns_search_parents are passed to
1165 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1166 of host_find_byname() use the default settings of RES_DEFNAMES
1167 (qualify_single) but not RES_DNSRCH (search_parents).

1170 spool_read_header() do less string testing, by means of a preliminary
1171 switch on the second character of optional "-foo" lines. (This is
1172 overdue, caused by the large number of possibilities that now exist.
1173 Originally there were few.) While I was there, I also converted the
1174 str(n)cmp tests so they don't re-test the leading "-" and the first
1175 character, in the hope this might squeeze out yet more improvement.

1177PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1178 flag allowing group syntax was set by the header_syntax check but not
1179 turned off, possible causing trouble later; (2) The flag was not being
1180 set at all for the header_verify test, causing "group"-style headers to
1181 be rejected. I have now set it in this case, and also caused header_
1182 verify to ignore an empty address taken from a group. While doing this, I
1183 came across some other cases where the code for allowing group syntax
1184 while scanning a header line wasn't quite right (mostly, not resetting
1185 the flag correctly in the right place). These bugs could have caused
1186 trouble for malformed header lines. I hope it is now all correct.

1188PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1194PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

1196 embargo. It requires special client support, and Exim is probably the
1197 only MTA that supported it -- and would never use it because real RSA is
1198 always available. This code has been removed, because it had the bad

1202PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1203 authenticator to fail if there's a tab character in the incoming data
1204 (there should never be unless someone is messing about, as it's supposed
1205 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1206 if the connection is using TLS or if the remote IP is the same as the
1207 local IP, and the "valid-client-cert option" if a client certificate has
1208 been verified.

1239
1240PH/30 Exim was sometimes attempting to deliver messages that had suffered
1241 address errors (4xx response to RCPT) over the same connection as other
1242 messages routed to the same hosts. Such deliveries are always "forced",
1243 so retry times are not inspected. This resulted in far too many retries
1244 for the affected addresses. The effect occurred only when there were more
1245 hosts than the hosts_max_try setting in the smtp transport when it had
1246 the 4xx errors. Those hosts that it had tried were not added to the list
1247 of hosts for which the message was waiting, so if all were tried, there
1248 was no problem. Two fixes have been applied:
1249
1250 (i) If there are any address or message errors in an SMTP delivery, none
1251 of the hosts (tried or untried) are now added to the list of hosts
1252 for which the message is waiting, so the message should not be a
1253 candidate for sending over the same connection that was used for a
1254 successful delivery of some other message. This seems entirely
1255 reasonable: after all the message is NOT "waiting for some host".
1256 This is so "obvious" that I'm not sure why it wasn't done
1257 previously. Hope I haven't missed anything, but it can't do any
1258 harm, as the worst effect is to miss an optimization.
1259
1260 (ii) If, despite (i), such a delivery is accidentally attempted, the
1261 routing retry time is respected, so at least it doesn't keep
1262 hammering the server.

PH
1277PH/35 The error "getsockname() failed: connection reset by peer" was being
1278 written to the panic log as well as the main log, but it isn't really
1279 panic-worthy as it just means the connection died rather early on. I have
1280 removed the panic log writing for the ECONNRESET error when getsockname()
1281 fails.
1282
48c7f9e2
PH
1283PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1284 runs only) independently of the message's sender address. This meant
1285 that, if the 4xx error was in fact related to the sender, a different
1286 message to the same recipient with a different sender could confuse
1287 things. In particualar, this can happen when sending to a greylisting
1288 server, but other circumstances could also provoke similar problems.
1289 I have changed the default so that the retry time for these errors is now
1290 based a combination of the sender and recipient addresses. This change
1291 can be overridden by setting address_retry_include_sender=false in the
1292 smtp transport.

1565 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1566 554 error is used if errno is still zero or contains ENOENT (which occurs

PH
1590PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1591 folder from quota calculations, a direct delivery into this folder messed
1592 up the contents of the maildirsize file. This was because the regex was
1593 used only to exclude .Trash (or whatever) when the size of the mailbox
1594 was calculated. There was no check that a delivery was happening into an
1595 excluded directory. This bug has been fixed by ignoring all quota
1596 processing for deliveries into excluded directories.

1603
1604PH/01 The code for finding all the local interface addresses on a FreeBSD
1605 system running IPv6 was broken. This may well have applied to all BSD
1606 systems, as well as to others that have similar system calls. The broken
1607 code found IPv4 interfaces correctly, but gave incorrect values for the
1608 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1609 that it would not match correctly against @[] and not recognize the IPv6
1610 addresses as local.

1620 invalid. However, $reply_address has leading white space removed, and all

1651 syntactically invalid From: or Reply-to: line, and a filter used this to
1652 generate an autoreply, and therefore failed to obtain an address for the
1653 autoreply, Exim could try to deliver to a non-existent relative file
1654 name, causing unrelated and misleading errors. What now happens is that
1655 it logs this as a hard delivery error, but does not attempt to create a

1670PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

1673 non-existent - all you got was a failure to exec. I have made two
1674 changes:
1675
1676 (a) Failures to set uid/gid, the current directory, or a process leader
1677 in a subprocess such as that created by queryprogram now generate
1678 suitable debugging ouput when -d is set.
1679
1680 (b) The queryprogram router detects when it is not running as root,
1681 outputs suitable debugging information if -d is set, and then runs
1682 the subprocess without attempting to change uid/gid.

PH
1687PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1688 additional section of a DNS packet that returns MX or SRV records.
1689 Instead, it always explicitly searches for A/AAAA records. This avoids
1690 major problems that occur when a DNS server includes only records of one
1691 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1692 fixed another bug: if SRV records were looked up and the corresponding
1693 address records were *not* found in the additional section, the port
1694 values from the SRV records were lost.

1696PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1700PH/18 If quota_warn_message contains a From: header, Exim now refrains from

1703
727071f8
PH
1704PH/19 When calculating a retry time, Exim used to measure the "time since
1705 failure" by looking at the "first failed" field in the retry record. Now
1706 it does not use this if it is later than than the arrival time of the
1707 message. Instead it uses the arrival time. This makes for better
1708 behaviour in cases where some deliveries succeed, thus re-setting the
1709 "first failed" field. An example is a quota failure for a huge message
1710 when small messages continue to be delivered. Without this change, the
1711 "time since failure" will always be short, possible causing more frequent
1712 delivery attempts for the huge message than are intended.

PH
1809PH/42 The content-scanning code uses fopen() to create files in which to put
1810 message data. Previously it was not paying any attention to the mode of
1811 the files. Exim runs with umask(0) because the rest of the code creates
1812 files with open(), and sets the required mode explicitly. Thus, these
1813 files were ending up world-writeable. This was not a big issue, because,
1814 being within the spool directory, they were not world-accessible. I have
1815 created a function called modefopen, which takes an additional mode
1816 argument. It sets umask(777), creates the file, chmods it to the required
1817 mode, then resets the umask. All the relevant calls to fopen() in the
1818 content scanning code have been changed to use this function.

1830 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1831 they are received. Thus, the responses can be made to depend on the

1853PH/52 Two bugs concerned with error handling when the smtp transport is
1854 used in LMTP mode:
1855
1856 (i) Exim was not creating retry information for temporary errors given
1857 for individual recipients after the DATA command when the smtp transport
1858 was used in LMTP mode. This meant that they could be retried too
1859 frequently, and not timed out correctly.
1860
1861 (ii) Exim was setting the flag that allows error details to be returned
1862 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1863 recipients that were returned after the DATA command.
1864
1865PH/53 This is related to PH/52, but is more general: for any failing address,
1866 when detailed error information was permitted to be returned to the
1867 sender, but the error was temporary, then after the final timeout, only
1868 "retry timeout exceeded" was returned. Now it returns the full error as

1939PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1940 function verify_get_ident() calls ip_connect() to connect a socket, but
1941 if the "connect()" function timed out, ip_connect() used to close the
1942 socket. However, verify_get_ident() also closes the socket later, and in
1943 between Exim writes to the log, which may get opened at this point. When
1944 the socket was closed in ip_connect(), the log could get the same file
1945 descriptor number as the socket. This naturally causes chaos. The fix is
1946 not to close the socket in ip_connect(); the socket should be closed by
1947 the function that creates it. There was only one place in the code where
1948 this was missing, in the iplookup router, which I don't think anybody now
1949 uses, but I've fixed it anyway.

2006 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2007 not being looked up in the rDNS to get a host name, Exim was showing the
2008 IP address twice in Received: lines, even though the IP addresses were
2009 identical. For example:
2010
2011 Received: from [1.2.3.4] (helo=[1.2.3.4])
2012
2013 However, if the real host name was known, it was omitting the HELO data
2014 if it matched the actual IP address. This has been tidied up so that it
2015 doesn't show the same IP address twice.

2047 warnings). In the case of bounce messages for non-SMTP mesages, there was
2048 also a typo: it was using "Auto_submitted" (underscore instead of
2049 hyphen). Since every message generated by Exim is necessarily in response
2050 to another message, thes have all been changed to:

2052 Auto-Submitted: auto-replied

2106 the IP address, check_host() was doing a simple string comparison with
2107 addresses acquired from the DNS when checking that the found name did
2108 have the original IP as one of its addresses. Since any found IPv6
2109 addresses are likely to be in abbreviated form, the comparison could
2110 fail. Luckily, there already exists a function for doing the comparison
2111 by converting both addresses to binary, so now that is used instead of
2112 the text comparison.

2409PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2410 with the definition in sysexits.h (which is #included earlier).
2411 Fortunately, Exim does not actually use EX_OK. The code used to try to
2412 preserve the sysexits.h value, by assumimg that macro definitions were
2413 scanned for macro replacements. I have been disabused of this notion,
2414 so now the code just undefines EX_OK before #including unistd.h.

2416PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout

2419 This seems wrong - if the receiver was accepting one byte at a time it
2420 would take for ever. The timeout is now adjusted when this happens. It
2421 doesn't have to be particularly precise.

2498 suddenly stopped working when I started to use syslog. The patch checks

2629
2630PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2631 that changes the way the GnuTLS parameters are stored in the cache file.
2632 The new format can be generated externally. For backward compatibility,
2633 if the data in the cache doesn't make sense, Exim assumes it has read an
2634 old-format file, and it generates new data and writes a new file. This
2635 means that you can't go back to an older release without removing the
2636 file.
2637
2638PH/03 A redirect router that has both "unseen" and "one_time" set does not
2639 work if there are any delivery delays because "one_time" forces the
2640 parent to be marked "delivered", so its unseen clone is never tried
2641 again. For this reason, Exim now forbids the simultaneous setting of
2642 these two options.
2643
2644PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2645 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2646 entry if you want to know the details. The fix, however, neglected to
2647 consider the case when local delivery batching is involved. The test for
2648 "previously delivered" was not happening when checking to see if an
2649 address could be batched with a previous (undelivered) one; under
2650 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2651 address.

2653PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2656PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2657 header_syntax) but Exim was just ignoring anything given after a slash.
2658 In particular, this caused confusion with an attempt to use "verify =
2659 reverse_host_lookup/defer_ok". An error is now given when options are
2660 supplied for verify items that do not have them. (Maybe reverse_host_
2661 lookup should have a defer_ok option, but that's a different point.)

2663PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2716 the file with the wrong ownership). There was no test for failure of this
2717 fork() call, which would lead to the process getting stuck as it waited

2739PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2740 hadn't been configured. The fix is from Juergen Kreileder, who
2741 understands it better than I do:
2742
2743 "Here's what I see happening with three configured cyrus_sasl
2744 authenticators configured (plain, login, cram-md5):
2745
2746 On startup auth_cyrus_sasl_init() gets called for each of these.
2747 This means three calls to sasl_listmech() without a specified mech_list.
2748 => SASL tests which mechs of all available mechs actually work
2749 => three warnings about OTP not working
2750 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2751
2752 With the patch, sasl_listmech() also gets called three times. But now
2753 SASL's mech_list option is set to the server_mech specified in the the
2754 authenticator. Or in other words, the answer from sasl_listmech()
2755 gets limited to just the mech you're testing for (which is different
2756 for each call.)
2757 => the return list contains just 'plain' or 'login', 'cram-md5' or
2758 nothing depending on the value of ob->server_mech.
2759

2793PH/30 In these circumstances:
2794 . Two addresses routed to the same list of hosts;
2795 . First host does not offer TLS;
2796 . First host accepts first address;
2797 . First host gives temporary error to second address;
2798 . Second host offers TLS and a TLS session is established;
2799 . Second host accepts second address.
2800 Exim incorrectly logged both deliveries with the TLS parameters (cipher

2802 address.

2804PH/31 When doing a callout as part of verifying an address, Exim was not paying

PH
2826PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2827 the grounds that routing the same address twice would always produce the
2828 same answer. This might have been true once, but it is certainly no
2829 longer true now. Routing a child address may depend on the previous
2830 routing that produced that child. Some complicated redirection strategies
2831 went wrong when messages had multiple recipients, and made Exim's
2832 behaviour dependent on the order in which the addresses were given.
2833
2834 I have moved the duplicate checking until after the routing is complete.
2835 Exim scans the addresses that are assigned to local and remote
2836 transports, and removes any duplicates. This means that more work will be
2837 done, as duplicates will always all be routed, but duplicates are
2838 presumably rare, so I don't expect this is of any significance.
2839
2840 For deliveries to pipes, files, and autoreplies, the duplicate checking
2841 still happens during the routing process, since they are not going to be
2842 routed further.

2848 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2849 blindly assumes that writes won't block so it may never time out."

2871 (e) A message specified by the cannot_route_message router option.
2872

2874 warning messages. There are also a few cases where bland messages such
2875 as "unrouteable address" or "local delivery error" are given.

2886 successful delivery. Such timeouts include transport filter timeouts. For
2887 consistency with the overall process timeout, these timeouts are now
2888 treated as errors, giving rise to delivery failures by default. However,
2889 there is now a new Boolean option for the pipe transport called
2890 timeout_defer, which, if set TRUE, converts the failures into defers for
2891 both kinds of timeout. A transport filter timeout is now identified in

2901A note about Exim versions 4.44 and 4.50
2902----------------------------------------
2903
2904Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2905changes of various kinds. As a consequence, a big documentation update was
2906needed. This delayed the release for rather longer than seemed good, especially
2907in the light of a couple of (minor) security issues. Therefore, the changes
2908that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2909release. So 4.44 and 4.50 are in effect two different branches that both start
2910from 4.43.
2911
2912I have left the 4.50 change log unchanged; it contains all the changes since
29134.43. The change log for 4.44 is below; many of its items are identical to
2914those for 4.50. This seems to be the most sensible way to preserve the
2915historical information.

PH
2933 5. There are several places where Exim runs a non-Exim command in a
2934 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2935 was being done only for the command run by the queryprogram router. It is
2936 now done for all such subprocesses. The other cases are: ${run, transport
2937 filters, and the commands run by the lmtp and pipe transports.

2939 6. Added CONFIGURE_GROUP build-time option.
2940
2941 7. Some older OS have a limit of 256 on the maximum number of file
2942 descriptors. Exim was using setrlimit() to set 1000 as a large value
2943 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2944 systems. I've change it so that if it can't get 1000, it tries for 256.

2946 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2947 was an oversight, and furthermore, ever since the addition of extra
2948 controls (e.g. 4.43/32), the checks on when to allow different forms of
2949 "control" were broken. There should now be diagnostics for all cases when a
2950 control that does not make sense is encountered.

299122. $host_address is now set to the target address during the checking of
2992 ignore_target_hosts.
2993
299423. When checking ignore_target_hosts for an ipliteral router, no host name was
2995 being passed; this would have caused $sender_host_name to have been used if
2996 matching the list had actually called for a host name (not very likely,
2997 since this list is usually IP addresses). A host name is now passed as
2998 "[x.x.x.x]".
2999

PH
300024. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3001 code that specifies a non-restarting handler (typically sigaction() in
3002 modern systems) in an attempt to fix a rare and obscure crash bug.
3003
300425. Narrowed the window for a race in the daemon that could cause it to ignore
3005 SIGCHLD signals. This is not a major problem, because they are used only to
3006 wake it up if nothing else does.
3007
62c0818f
PH
300826. A malformed maildirsize file could cause Exim to calculate negative values
3009 for the mailbox size or file count. Odd effects could occur as a result.
3010 The maildirsize information is now recalculated if the size or filecount
3011 end up negative.
3012
26034054
PH
301327. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this

301628. Installed the latest version of exipick from John Jetmore.
3017
90af77f4
PH
301829. In an address list, if the pattern was not a regular expression, an empty
3019 subject address (from a bounce message) matched only if the pattern was an
3020 empty string. Non-empty patterns were not even tested. This was the wrong
3021 because it is perfectly reasonable to use an empty address as part of a
3022 database query. An empty address is now tested by patterns that are
3023 lookups. However, all the other forms of pattern expect the subject to
3024 contain a local part and a domain, and therefore, for them, an empty
3025 address still always fails if the pattern is not itself empty.
3026
d8ef3577
PH
302730. Exim went into a mad DNS loop when attempting to do a callout where the
3028 host was specified on an smtp transport, and looking it up yielded more
3029 than one IP address.
3030
5cb8cbc6
PH
303131. Re-factored the code for checking spool and log partition space into a
3032 function that finds that data and another that does the check. The former
3033 is then used to implement four new variables: $spool_space, $log_space,
3034 $spool_inodes, and $log_inodes.
3035
14702f5b
PH
303632. The RFC2047 encoding function was originally intended for short strings
3037 such as real names; it was not keeping to the 75-character limit for
3038 encoded words that the RFC imposes. It now respects the limit, and
3039 generates multiple encoded words if necessary. To be on the safe side, I
3040 have increased the buffer size for the ${rfc2047: expansion operator from
3041 1024 to 2048 bytes.
3042
063b1e99
PH
304333. It is now permitted to omit both strings after an "if" condition; if the
3044 condition is true, the result is "true". As before, when the second string
3045 is omitted, a false condition yields an empty string. This makes it less
3046 cumbersome to write custom ACL and router conditions.
3047
652e1b65
PH
304834. Failure to deliver a bounce message always caused it to be frozen, even if
3049 there was an errors_to setting on the router. The errors_to setting is now
3050 respected.
3051
6f0c9a4f
PH
305235. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3053 canonical form (fully expanded) before being placed in
3054 $sender_host_address.
3055
33397d19
PH
305636. The table in the code that translates DNS record types into text (T_A to
3057 "A" for instance) was missing entries for NS and CNAME. It is just possible
3058 that this could have caused confusion if both these types were looked up
3059 for the same domain, because the text type is used as part of Exim's
3060 per-process caching. But the chance of anyone hitting this buglet seems
3061 very small.
3062
7bb56e1f
PH
306337. The dnsdb lookup has been extended in a number of ways.
3064
3065 (1) There is a new type, "zns", which walks up the domain tree until it
3066 finds some nameserver records. It should be used with care.
3067
ea3bc19b
PH
3068 (2) There is a new type, "mxh", which is like "mx" except that it returns
3069 just the host names, not the priorities.

3073 controlled by a keyword.

PH
308741. Include certificate and key file names in error message when GnuTLS fails

3098 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3099 < 0 before doing a fflush(). This bug looks as though it goes back to the
3100 introduction of TLS in release 3.20, but "sometimes" must have been rare
3101 because the tests only now provoked it.

PH
312552. Exim crashed if a remote delivery caused a very long error message to be
3126 recorded - for instance if somebody sent an entire SpamAssassin report back
3127 as a large number of 550 error lines. This bug was coincidentally fixed by
3128 increasing the size of one of Exim's internal buffers (big_buffer) that
3129 happened as part of the Exiscan merge. However, to be on the safe side, I
3130 have made the code more robust (and fixed the comments that describe what
3131 is going on).

PH
313854. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3139 patch that reportedly fixes this has been added. I am not expert enough to
3140 create a test for it. This is what the patch creator wrote:
3141
3142 "I found a little strange behaviour of ldap code when working with
3143 Windows 2003 AD Domain, where users was placed in more than one
3144 Organization Units. When I tried to give exim partial DN, the exit code
3145 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3146 But simultaneously result of request was absolutely normal ldap result,
3147 so I produce this patch..."
3148
3295e65b
PH
3149 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3150 REFERENCE, so I have modified the code to exclude the patch when that macro
3151 is not defined.

3154 keys for these records are domain names, not reversed IP addresses. The
b975ba52

3155 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3156 leaves it alone. Component reversal etc. now happens only for IP addresses.

317360. The host_aton() function is supposed to be passed a string that is known
3174 to be a valid IP address. However, in the case of IPv6 addresses, it was
3175 not checking this. This is a hostage to fortune. Exim now panics and dies
3176 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3177 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3178 components; fortuitously, this particular loophole had already been fixed
3179 by change 4.50/55 above.
3180
3181 If there are any other similar loopholes, the new check in host_aton()
3182 itself should stop them being exploited. The report I received stated that
3183 data on the command line could provoke the exploit when Exim was running as
3184 exim, but did not say which command line option was involved. All I could
3185 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3186 running as the user.

3188
318961. There was a buffer overflow vulnerability in the SPA authentication code
3190 (which came originally from the Samba project). I have added a test to the
3191 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3192 CAN-2005-0022

319462. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3195 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3196

PH
319763. The daemon start-up calls getloadavg() while still root for those OS that
3198 need the first call to be done as root, but it missed one case: when
3199 deliver_queue_load_max is set with deliver_drop_privilege. This is
3200 necessary for the benefit of the queue runner, because there is no re-exec
3201 when deliver_drop_privilege is set.
3202

PH
320364. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3204 This has been fixed.
3205
60dc5e56
PH
320665. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3207 was in use, was not putting the data itself into the right store pool;
3208 consequently, it could be overwritten for a subsequent message in the same
3209 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3210 the caching.)
3211

PH
321266. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3213
a5a28604
PH
321467. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3215 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3216 the function were treating the return as a boolean value, which happened to
3217 work because 0=false and not-0=true, but is not correct code.
3218
7e634d24
PH
321968. The host_aton() function was not handling scoped IPv6 addresses (those
3220 with, for example, "%eth0" on the end) correctly.
3221
3e11c26b
PH
322269. Fixed some compiler warnings in acl.c for the bitmaps specified with
3223 negated items (that is, ~something) in unsigned ints. Some compilers
3224 apparently mutter when there is no cast.
3225
6729cf78
PH
322670. If an address verification called from an ACL failed, and did not produce a
3227 user-specific message (i.e. there was only a "system" message), nothing was
3228 put in $acl_verify_message. In this situation, it now puts the system
3229 message there.
3230
00f00ca5
PH
323171. Change 4.23/11 added synchronization checking at the start of an SMTP
3232 session; change 4.31/43 added the unwanted input to the log line - except
3233 that it did not do this in the start of session case. It now does.
3234
c9bdd01c
PH
323572. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3236 This is wrong and can cause the other end to generate a synchronization
3237 error if it is another Exim or anything else that does the synchronization
3238 check. A QUIT command is no longer sent after a timeout.
3239
d43194df
PH
324073. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3241 during host lookups.
3242
fe5b5d0b
PH
324374. The defer_ok option of callout verification was not working if it was used
3244 when verifying addresses in header lines, that is, for this case:
3245
3246 verify = header_sender/callout=defer_ok
3247
76a2d7ba
PH
324875. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3249 those file descriptors could be used for SMTP connections. If anything
3250 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3251 could be sent to the SMTP client, causing chaos. The daemon now opens
3252 stdin, stdout, and stderr to /dev/null when it puts itself into the
3253 background.
3254
325576. Arrange for output from Perl's "warn" command to be written to Exim's main
3256 log by default. The user can override this with suitable Perl magic.
3257
04f7d5b9
PH
325877. The use of log_message on a "discard" ACL verb, which is supposed to add to
3259 the log message when discard triggers, was not working for the DATA ACL or
3260 for the non-SMTP ACL.
3261
bc60667e
PH
326278. Error message wording change in sieve.c.
3263
bb6e88ff
PH
326479. If smtp_accept_max_per_host was set, the number of connections could be
3265 restricted to fewer than expected, because the daemon was trying to set up
3266 a new connection before checking whether the processes handling previous
3267 connections had finished. The check for completed processes is now done
3268 earlier. On busy systems, this bug wouldn't be noticed because something
3269 else would have woken the daemon, and it would have reaped the completed
3270 process earlier.
3271
1e70f85b
PH
327280. If a message was submitted locally by a user whose login name contained one
3273 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3274 It caused a spool format error. I have fixed the spool reading code. A
3275 related problem was that the "from" clause in the Received: line became
3276 illegal because of the space(s). It is now covered by ${quote_local_part.
3277
327881. Included the latest eximstats from Steve (adds average sizes to HTML Top
3279 tables).

3292----------------------------------------------------
3293See the note above about the 4.44 and 4.50 releases.
3294----------------------------------------------------
3295
3296
3297Exim version 4.44
3298-----------------
3299
3300 1. Change 4.43/35 introduced a bug that caused file counts to be
3301 incorrectly computed when quota_filecount was set in an appendfile
3302 transport
3303
3304 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3305 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3306 place.
3307
3308 3. Give more explanation in the error message when the command for a transport
3309 filter fails to execute.
3310
3311 4. There are several places where Exim runs a non-Exim command in a
3312 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3313 was being done only for the command run by the queryprogram router. It is
3314 now done for all such subprocesses. The other cases are: ${run, transport
3315 filters, and the commands run by the lmtp and pipe transports.
3316
3317 5. Some older OS have a limit of 256 on the maximum number of file
3318 descriptors. Exim was using setrlimit() to set 1000 as a large value
3319 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3320 systems. I've change it so that if it can't get 1000, it tries for 256.
3321
3322 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3323 was an oversight, and furthermore, ever since the addition of extra
3324 controls (e.g. 4.43/32), the checks on when to allow different forms of
3325 "control" were broken. There should now be diagnostics for all cases when a
3326 control that does not make sense is encountered.
3327
3328 7. $recipients is now available in the predata ACL (oversight).
3329
3330 8. Tidy the search cache before the fork to do a delivery from a message
3331 received from the command line. Otherwise the child will trigger a lookup
3332 failure and thereby defer the delivery if it tries to use (for example) a
3333 cached ldap connection that the parent has called unbind on.
3334
3335 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3336 of $address_data from the recipient verification was clobbered by the
3337 sender verification.
3338
333910. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3340 was its contents. (It was OK if the option was not defined at all.)
3341
334211. A "Completed" log line is now written for messages that are removed from
3343 the spool by the -Mrm option.
3344
334512. $host_address is now set to the target address during the checking of
3346 ignore_target_hosts.
3347
334813. When checking ignore_target_hosts for an ipliteral router, no host name was
3349 being passed; this would have caused $sender_host_name to have been used if
3350 matching the list had actually called for a host name (not very likely,
3351 since this list is usually IP addresses). A host name is now passed as
3352 "[x.x.x.x]".
3353
335414. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3355 code that specifies a non-restarting handler (typically sigaction() in
3356 modern systems) in an attempt to fix a rare and obscure crash bug.
3357
335815. Narrowed the window for a race in the daemon that could cause it to ignore
3359 SIGCHLD signals. This is not a major problem, because they are used only to
3360 wake it up if nothing else does.
3361
336216. A malformed maildirsize file could cause Exim to calculate negative values
3363 for the mailbox size or file count. Odd effects could occur as a result.
3364 The maildirsize information is now recalculated if the size or filecount
3365 end up negative.
3366
336717. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3368 support for a long time. Removed HAVE_SYS_VFS_H.
3369
ea3a6f44 337018. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3371
337219. Allow an empty sender to be matched against a lookup in an address list.
3373 Previously the only cases considered were a regular expression, or an
3374 empty pattern.
3375
337620. Exim went into a mad DNS lookup loop when doing a callout where the
3377 host was specified on the transport, if the DNS lookup yielded more than
3378 one IP address.
3379
ea3a6f44
NM
338021. The RFC2047 encoding function was originally intended for short strings
3381 such as real names; it was not keeping to the 75-character limit for
3382 encoded words that the RFC imposes. It now respects the limit, and
3383 generates multiple encoded words if necessary. To be on the safe side, I
3384 have increased the buffer size for the ${rfc2047: expansion operator from
3385 1024 to 2048 bytes.
bbe902f0 3386
ea3a6f44
NM
338722. Failure to deliver a bounce message always caused it to be frozen, even if
3388 there was an errors_to setting on the router. The errors_to setting is now
3389 respected.
bbe902f0
PH
3390
339123. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3392 canonical form (fully expanded) before being placed in
3393 $sender_host_address.
3394
339524. Updated eximstats to version 1.33
3396
ea3a6f44
NM
339725. Include certificate and key file names in error message when GnuTLS fails
3398 to set them up, because the GnuTLS error message doesn't include the name
3399 of the failing file when there is a problem reading it.
bbe902f0
PH
3400
340126. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3402 As per change 25.
bbe902f0 3403
ea3a6f44
NM
340427. Reset the locale to "C" after calling embedded Perl, in case it was changed
3405 (this can affect the format of dates).
bbe902f0 3406
ea3a6f44
NM
340728. exim_tidydb, when checking for the continued existence of a message for
3408 which it has found a message-specific retry record, was not finding
3409 messages that were in split spool directories. Consequently, it was
3410 deleting retry records that should have stayed in existence.
