TF
57TF/03 Make the exiwhat support code safe for signals. Previously Exim might
58 lock up or crash if it happened to be inside a call to libc when it
59 got a SIGUSR1 from exiwhat.
60
61 The SIGUSR1 handler appends the current process status to the process
62 log which is later printed by exiwhat. It used to use the general
63 purpose logging code to do this, but several functions it calls are
64 not safe for signals.
65
66 The new output code in the SIGUSR1 handler is specific to the process
67 log, and simple enough that it's easy to inspect for signal safety.
68 Removing some special cases also simplifies the general logging code.
69 Removing the spurious timestamps from the process log simplifies
70 exiwhat.
71

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

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

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

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

807 if a client was not listed at all, or was listed with a value other than
808 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
809 the condition was not true (as it should be), so access was not denied.

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

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

1011PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1012 fixed by 4.65/MH/01 (is this a record?) are fixed:
1013
1014 (i) An empty string was always treated as zero by the numeric comparison
1015 operators. This behaviour has been restored.
1016
1017 (ii) It is documented that the numeric comparison operators always treat
1018 their arguments as decimal numbers. This was broken in that numbers
1019 starting with 0 were being interpreted as octal.
1020
1021 While fixing these problems I realized that there was another issue that
1022 hadn't been noticed. Values of message_size_limit (both the global option
1023 and the transport option) were treated as octal if they started with 0.
1024 The documentation was vague. These values are now always treated as
1025 decimal, and I will make that clear in the documentation.

1039PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

1041 is held in a short int, deliveries were likely to be lost. As such a
1042 large number of recipients for a single message is ridiculous
1043 (performance will be very, very poor), I have chosen to impose a limit
1044 rather than extend the field.

2b1c6e3a
PH
1069PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1070 callout verification, Exim cached a "reject" for the entire domain. This
1071 is correct for most verifications, but it is not correct for a recipient
1072 verification with use_sender or use_postmaster set, because in that case
1073 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1074 case of MAIL FROM:<> rejection from other early rejections (e.g.
1075 rejection of HELO). When verifying a recipient using a non-null MAIL
1076 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1077 Whatever the result of the callout, the value of the domain cache is
1078 left unchanged (for any other kind of callout, getting as far as trying
1079 RCPT means that the domain itself is ok).

1113PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1115 probably the interface on which it is arriving) and not to the outgoing
1116 callout (which could be using a different interface). This has been
1117 changed to use the value of the helo_data option from the smtp transport
1118 instead - this is what is used when a message is actually being sent. If
1119 there is no remote transport (possible with a router that sets up host
1120 addresses), $smtp_active_hostname is used.

7befa435 1123 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1124 (a) The code assumed that strncpy() returns a negative number on buffer
1125 overflow, which isn't the case. Replaced with Exim's string_format()
1126 function.
1127 (b) There were several signed/unsigned issues. I just did the minimum
1128 hacking in of casts. There is scope for a larger refactoring.
1129 (c) The code used strcasecmp() which is not a standard C function.
1130 Replaced with Exim's strcmpic() function.
1131 (d) The code set only $1; it now sets $auth1 as well.
1132 (e) A simple test gave the error "authentication client didn't specify
1133 service in request". It would seem that Dovecot has changed its
1134 interface. Fortunately there's a specification; I followed it and
1135 changed what the client sends and it appears to be working now.

1141 address A is aliased to B and C, where B exists and C does not. Without
1142 -v the output is "A verified" because verification stops after a
1143 successful redirection if more than one address is generated. However,
1144 with -v the child addresses are also verified. Exim was outputting "A
1145 failed to verify" and then showing the successful verification for C,
1146 with its parentage. It now outputs "B failed to verify", showing B's
1147 parentage before showing the successful verification of C.

1152
322050c2
PH
1153PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1154 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1155 they consult the DNS. I had assumed they would set it the way they
1156 wanted; and indeed my experiments on Linux seem to show that in some
1157 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1158 To be on the safe side, however, I have now made the interface to
1159 host_find_byname() similar to host_find_bydns(), with an argument
1160 containing the DNS resolver options. The host_find_byname() function now
1161 sets these options at its start, just as host_find_bydns() does. The smtp
1162 transport options dns_qualify_single and dns_search_parents are passed to
1163 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1164 of host_find_byname() use the default settings of RES_DEFNAMES
1165 (qualify_single) but not RES_DNSRCH (search_parents).

1168 spool_read_header() do less string testing, by means of a preliminary
1169 switch on the second character of optional "-foo" lines. (This is
1170 overdue, caused by the large number of possibilities that now exist.
1171 Originally there were few.) While I was there, I also converted the
1172 str(n)cmp tests so they don't re-test the leading "-" and the first
1173 character, in the hope this might squeeze out yet more improvement.

1175PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1176 flag allowing group syntax was set by the header_syntax check but not
1177 turned off, possible causing trouble later; (2) The flag was not being
1178 set at all for the header_verify test, causing "group"-style headers to
1179 be rejected. I have now set it in this case, and also caused header_
1180 verify to ignore an empty address taken from a group. While doing this, I
1181 came across some other cases where the code for allowing group syntax
1182 while scanning a header line wasn't quite right (mostly, not resetting
1183 the flag correctly in the right place). These bugs could have caused
1184 trouble for malformed header lines. I hope it is now all correct.

PH
1186PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1189 but it didn't always do it. This confused somebody who was copying the
1190 code for some other use. I have removed all the tests.

1192PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

1194 embargo. It requires special client support, and Exim is probably the
1195 only MTA that supported it -- and would never use it because real RSA is

1200PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1201 authenticator to fail if there's a tab character in the incoming data
1202 (there should never be unless someone is messing about, as it's supposed
1203 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1204 if the connection is using TLS or if the remote IP is the same as the
1205 local IP, and the "valid-client-cert option" if a client certificate has
1206 been verified.

1237
1238PH/30 Exim was sometimes attempting to deliver messages that had suffered
1239 address errors (4xx response to RCPT) over the same connection as other
1240 messages routed to the same hosts. Such deliveries are always "forced",
1241 so retry times are not inspected. This resulted in far too many retries
1242 for the affected addresses. The effect occurred only when there were more
1243 hosts than the hosts_max_try setting in the smtp transport when it had
1244 the 4xx errors. Those hosts that it had tried were not added to the list
1245 of hosts for which the message was waiting, so if all were tried, there
1246 was no problem. Two fixes have been applied:
1247
1248 (i) If there are any address or message errors in an SMTP delivery, none
1249 of the hosts (tried or untried) are now added to the list of hosts
1250 for which the message is waiting, so the message should not be a
1251 candidate for sending over the same connection that was used for a
1252 successful delivery of some other message. This seems entirely
1253 reasonable: after all the message is NOT "waiting for some host".
1254 This is so "obvious" that I'm not sure why it wasn't done
1255 previously. Hope I haven't missed anything, but it can't do any
1256 harm, as the worst effect is to miss an optimization.
1257
1258 (ii) If, despite (i), such a delivery is accidentally attempted, the
1259 routing retry time is respected, so at least it doesn't keep
1260 hammering the server.

1275PH/35 The error "getsockname() failed: connection reset by peer" was being
1276 written to the panic log as well as the main log, but it isn't really
1277 panic-worthy as it just means the connection died rather early on. I have
1278 removed the panic log writing for the ECONNRESET error when getsockname()
1279 fails.
1280
48c7f9e2
PH
1281PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1282 runs only) independently of the message's sender address. This meant
1283 that, if the 4xx error was in fact related to the sender, a different
1284 message to the same recipient with a different sender could confuse
1285 things. In particualar, this can happen when sending to a greylisting
1286 server, but other circumstances could also provoke similar problems.
1287 I have changed the default so that the retry time for these errors is now
1288 based a combination of the sender and recipient addresses. This change
1289 can be overridden by setting address_retry_include_sender=false in the
1290 smtp transport.

1564 554 error is used if errno is still zero or contains ENOENT (which occurs

PH
1588PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1589 folder from quota calculations, a direct delivery into this folder messed
1590 up the contents of the maildirsize file. This was because the regex was
1591 used only to exclude .Trash (or whatever) when the size of the mailbox
1592 was calculated. There was no check that a delivery was happening into an
1593 excluded directory. This bug has been fixed by ignoring all quota
1594 processing for deliveries into excluded directories.

1601
1602PH/01 The code for finding all the local interface addresses on a FreeBSD
1603 system running IPv6 was broken. This may well have applied to all BSD
1604 systems, as well as to others that have similar system calls. The broken
1605 code found IPv4 interfaces correctly, but gave incorrect values for the
1606 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1607 that it would not match correctly against @[] and not recognize the IPv6
1608 addresses as local.

1649 syntactically invalid From: or Reply-to: line, and a filter used this to
1650 generate an autoreply, and therefore failed to obtain an address for the
1651 autoreply, Exim could try to deliver to a non-existent relative file
1652 name, causing unrelated and misleading errors. What now happens is that
1653 it logs this as a hard delivery error, but does not attempt to create a

1668PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

1671 non-existent - all you got was a failure to exec. I have made two
1672 changes:
1673
1674 (a) Failures to set uid/gid, the current directory, or a process leader
1675 in a subprocess such as that created by queryprogram now generate
1676 suitable debugging ouput when -d is set.
1677
1678 (b) The queryprogram router detects when it is not running as root,
1679 outputs suitable debugging information if -d is set, and then runs
1680 the subprocess without attempting to change uid/gid.

PH
1685PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1686 additional section of a DNS packet that returns MX or SRV records.
1687 Instead, it always explicitly searches for A/AAAA records. This avoids
1688 major problems that occur when a DNS server includes only records of one
1689 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1690 fixed another bug: if SRV records were looked up and the corresponding
1691 address records were *not* found in the additional section, the port
1692 values from the SRV records were lost.

1694PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

1701
727071f8
PH
1702PH/19 When calculating a retry time, Exim used to measure the "time since
1703 failure" by looking at the "first failed" field in the retry record. Now
1704 it does not use this if it is later than than the arrival time of the
1705 message. Instead it uses the arrival time. This makes for better
1706 behaviour in cases where some deliveries succeed, thus re-setting the
1707 "first failed" field. An example is a quota failure for a huge message
1708 when small messages continue to be delivered. Without this change, the
1709 "time since failure" will always be short, possible causing more frequent
1710 delivery attempts for the huge message than are intended.

PH
1807PH/42 The content-scanning code uses fopen() to create files in which to put
1808 message data. Previously it was not paying any attention to the mode of
1809 the files. Exim runs with umask(0) because the rest of the code creates
1810 files with open(), and sets the required mode explicitly. Thus, these
1811 files were ending up world-writeable. This was not a big issue, because,
1812 being within the spool directory, they were not world-accessible. I have
1813 created a function called modefopen, which takes an additional mode
1814 argument. It sets umask(777), creates the file, chmods it to the required
1815 mode, then resets the umask. All the relevant calls to fopen() in the
1816 content scanning code have been changed to use this function.

1828 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1829 they are received. Thus, the responses can be made to depend on the

1851PH/52 Two bugs concerned with error handling when the smtp transport is
1852 used in LMTP mode:
1853
1854 (i) Exim was not creating retry information for temporary errors given
1855 for individual recipients after the DATA command when the smtp transport
1856 was used in LMTP mode. This meant that they could be retried too
1857 frequently, and not timed out correctly.
1858
1859 (ii) Exim was setting the flag that allows error details to be returned
1860 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1861 recipients that were returned after the DATA command.
1862
1863PH/53 This is related to PH/52, but is more general: for any failing address,
1864 when detailed error information was permitted to be returned to the
1865 sender, but the error was temporary, then after the final timeout, only
1866 "retry timeout exceeded" was returned. Now it returns the full error as

1937PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1938 function verify_get_ident() calls ip_connect() to connect a socket, but
1939 if the "connect()" function timed out, ip_connect() used to close the
1940 socket. However, verify_get_ident() also closes the socket later, and in
1941 between Exim writes to the log, which may get opened at this point. When
1942 the socket was closed in ip_connect(), the log could get the same file
1943 descriptor number as the socket. This naturally causes chaos. The fix is
1944 not to close the socket in ip_connect(); the socket should be closed by
1945 the function that creates it. There was only one place in the code where
1946 this was missing, in the iplookup router, which I don't think anybody now
1947 uses, but I've fixed it anyway.

2004 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2005 not being looked up in the rDNS to get a host name, Exim was showing the
2006 IP address twice in Received: lines, even though the IP addresses were
2007 identical. For example:
2008
2009 Received: from [1.2.3.4] (helo=[1.2.3.4])
2010
2011 However, if the real host name was known, it was omitting the HELO data

2013 doesn't show the same IP address twice.

2045 warnings). In the case of bounce messages for non-SMTP mesages, there was
2046 also a typo: it was using "Auto_submitted" (underscore instead of
2047 hyphen). Since every message generated by Exim is necessarily in response
2048 to another message, thes have all been changed to:
2049
2050 Auto-Submitted: auto-replied
2051
2052 in accordance with these statements in the RFC:

2102PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2104 the IP address, check_host() was doing a simple string comparison with
2105 addresses acquired from the DNS when checking that the found name did
2106 have the original IP as one of its addresses. Since any found IPv6
2107 addresses are likely to be in abbreviated form, the comparison could
2108 fail. Luckily, there already exists a function for doing the comparison
2109 by converting both addresses to binary, so now that is used instead of
2110 the text comparison.

2407PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2408 with the definition in sysexits.h (which is #included earlier).
2409 Fortunately, Exim does not actually use EX_OK. The code used to try to
2410 preserve the sysexits.h value, by assumimg that macro definitions were
2411 scanned for macro replacements. I have been disabused of this notion,
2412 so now the code just undefines EX_OK before #including unistd.h.

2414PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout

2417 This seems wrong - if the receiver was accepting one byte at a time it
2418 would take for ever. The timeout is now adjusted when this happens. It
2419 doesn't have to be particularly precise.

2496 suddenly stopped working when I started to use syslog. The patch checks

2628PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2629 that changes the way the GnuTLS parameters are stored in the cache file.
2630 The new format can be generated externally. For backward compatibility,
2631 if the data in the cache doesn't make sense, Exim assumes it has read an
2632 old-format file, and it generates new data and writes a new file. This
2633 means that you can't go back to an older release without removing the
2634 file.
2635
2636PH/03 A redirect router that has both "unseen" and "one_time" set does not
2637 work if there are any delivery delays because "one_time" forces the
2638 parent to be marked "delivered", so its unseen clone is never tried
2639 again. For this reason, Exim now forbids the simultaneous setting of
2640 these two options.
2641
2642PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2643 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2644 entry if you want to know the details. The fix, however, neglected to
2645 consider the case when local delivery batching is involved. The test for
2646 "previously delivered" was not happening when checking to see if an
2647 address could be batched with a previous (undelivered) one; under
2648 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2649 address.

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

2661PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2714 the file with the wrong ownership). There was no test for failure of this
2715 fork() call, which would lead to the process getting stuck as it waited

2737PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

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

2792 . Two addresses routed to the same list of hosts;

2795 . First host gives temporary error to second address;
2796 . Second host offers TLS and a TLS session is established;
2797 . Second host accepts second address.
2798 Exim incorrectly logged both deliveries with the TLS parameters (cipher

PH
2824PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2825 the grounds that routing the same address twice would always produce the
2826 same answer. This might have been true once, but it is certainly no
2827 longer true now. Routing a child address may depend on the previous
2828 routing that produced that child. Some complicated redirection strategies
2829 went wrong when messages had multiple recipients, and made Exim's
2830 behaviour dependent on the order in which the addresses were given.
2831
2832 I have moved the duplicate checking until after the routing is complete.
2833 Exim scans the addresses that are assigned to local and remote
2834 transports, and removes any duplicates. This means that more work will be
2835 done, as duplicates will always all be routed, but duplicates are
2836 presumably rare, so I don't expect this is of any significance.
2837
2838 For deliveries to pipes, files, and autoreplies, the duplicate checking
2839 still happens during the routing process, since they are not going to be
2840 routed further.

2846 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2847 blindly assumes that writes won't block so it may never time out."

2869 (e) A message specified by the cannot_route_message router option.

2873 as "unrouteable address" or "local delivery error" are given.

2884 successful delivery. Such timeouts include transport filter timeouts. For
2885 consistency with the overall process timeout, these timeouts are now
2886 treated as errors, giving rise to delivery failures by default. However,
2887 there is now a new Boolean option for the pipe transport called
2888 timeout_defer, which, if set TRUE, converts the failures into defers for
2889 both kinds of timeout. A transport filter timeout is now identified in

2899A note about Exim versions 4.44 and 4.50
2900----------------------------------------
2901
2902Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2903changes of various kinds. As a consequence, a big documentation update was
2904needed. This delayed the release for rather longer than seemed good, especially
2905in the light of a couple of (minor) security issues. Therefore, the changes
2906that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2907release. So 4.44 and 4.50 are in effect two different branches that both start
2908from 4.43.
2909
2910I have left the 4.50 change log unchanged; it contains all the changes since
29114.43. The change log for 4.44 is below; many of its items are identical to
2912those for 4.50. This seems to be the most sensible way to preserve the
2913historical information.

PH
2931 5. There are several places where Exim runs a non-Exim command in a
2932 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2933 was being done only for the command run by the queryprogram router. It is
2934 now done for all such subprocesses. The other cases are: ${run, transport
2935 filters, and the commands run by the lmtp and pipe transports.

2937 6. Added CONFIGURE_GROUP build-time option.
2938
2939 7. Some older OS have a limit of 256 on the maximum number of file
2940 descriptors. Exim was using setrlimit() to set 1000 as a large value
2941 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2942 systems. I've change it so that if it can't get 1000, it tries for 256.

2944 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2945 was an oversight, and furthermore, ever since the addition of extra
2946 controls (e.g. 4.43/32), the checks on when to allow different forms of
2947 "control" were broken. There should now be diagnostics for all cases when a
2948 control that does not make sense is encountered.

298922. $host_address is now set to the target address during the checking of
2990 ignore_target_hosts.
2991
299223. When checking ignore_target_hosts for an ipliteral router, no host name was
2993 being passed; this would have caused $sender_host_name to have been used if
2994 matching the list had actually called for a host name (not very likely,
2995 since this list is usually IP addresses). A host name is now passed as
2996 "[x.x.x.x]".
2997
7d468ab8
PH
299824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2999 code that specifies a non-restarting handler (typically sigaction() in
3000 modern systems) in an attempt to fix a rare and obscure crash bug.
3001
300225. Narrowed the window for a race in the daemon that could cause it to ignore
3003 SIGCHLD signals. This is not a major problem, because they are used only to
3004 wake it up if nothing else does.
3005
62c0818f
PH
300626. A malformed maildirsize file could cause Exim to calculate negative values
3007 for the mailbox size or file count. Odd effects could occur as a result.
3008 The maildirsize information is now recalculated if the size or filecount
3009 end up negative.
3010
26034054
PH
301127. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3012 support for a long time. Removed HAVE_SYS_VFS_H.

301428. Installed the latest version of exipick from John Jetmore.
3015
90af77f4
PH
301629. In an address list, if the pattern was not a regular expression, an empty
3017 subject address (from a bounce message) matched only if the pattern was an
3018 empty string. Non-empty patterns were not even tested. This was the wrong
3019 because it is perfectly reasonable to use an empty address as part of a
3020 database query. An empty address is now tested by patterns that are
3021 lookups. However, all the other forms of pattern expect the subject to
3022 contain a local part and a domain, and therefore, for them, an empty
3023 address still always fails if the pattern is not itself empty.
3024
d8ef3577
PH
302530. Exim went into a mad DNS loop when attempting to do a callout where the
3026 host was specified on an smtp transport, and looking it up yielded more
3027 than one IP address.
3028
5cb8cbc6
PH
302931. Re-factored the code for checking spool and log partition space into a
3030 function that finds that data and another that does the check. The former
3031 is then used to implement four new variables: $spool_space, $log_space,
3032 $spool_inodes, and $log_inodes.
3033
14702f5b
PH
303432. The RFC2047 encoding function was originally intended for short strings
3035 such as real names; it was not keeping to the 75-character limit for
3036 encoded words that the RFC imposes. It now respects the limit, and
3037 generates multiple encoded words if necessary. To be on the safe side, I
3038 have increased the buffer size for the ${rfc2047: expansion operator from
3039 1024 to 2048 bytes.
3040
063b1e99
PH
304133. It is now permitted to omit both strings after an "if" condition; if the
3042 condition is true, the result is "true". As before, when the second string
3043 is omitted, a false condition yields an empty string. This makes it less
3044 cumbersome to write custom ACL and router conditions.
3045
652e1b65
PH
304634. Failure to deliver a bounce message always caused it to be frozen, even if
3047 there was an errors_to setting on the router. The errors_to setting is now
3048 respected.
3049
6f0c9a4f
PH
305035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3051 canonical form (fully expanded) before being placed in
3052 $sender_host_address.
3053
33397d19
PH
305436. The table in the code that translates DNS record types into text (T_A to
3055 "A" for instance) was missing entries for NS and CNAME. It is just possible
3056 that this could have caused confusion if both these types were looked up
3057 for the same domain, because the text type is used as part of Exim's
3058 per-process caching. But the chance of anyone hitting this buglet seems
3059 very small.
3060
7bb56e1f
PH
306137. The dnsdb lookup has been extended in a number of ways.
3062
3063 (1) There is a new type, "zns", which walks up the domain tree until it
3064 finds some nameserver records. It should be used with care.
3065
ea3bc19b
PH
3066 (2) There is a new type, "mxh", which is like "mx" except that it returns
3067 just the host names, not the priorities.

3070 looked up. The behaviour when one of the lookups defers can be
3071 controlled by a keyword.

PH
308541. Include certificate and key file names in error message when GnuTLS fails

3096 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3097 < 0 before doing a fflush(). This bug looks as though it goes back to the
3098 introduction of TLS in release 3.20, but "sometimes" must have been rare
3099 because the tests only now provoked it.

PH
312352. Exim crashed if a remote delivery caused a very long error message to be
3124 recorded - for instance if somebody sent an entire SpamAssassin report back
3125 as a large number of 550 error lines. This bug was coincidentally fixed by
3126 increasing the size of one of Exim's internal buffers (big_buffer) that
3127 happened as part of the Exiscan merge. However, to be on the safe side, I
3128 have made the code more robust (and fixed the comments that describe what
3129 is going on).

PH
313654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3137 patch that reportedly fixes this has been added. I am not expert enough to
3138 create a test for it. This is what the patch creator wrote:
3139
3140 "I found a little strange behaviour of ldap code when working with
3141 Windows 2003 AD Domain, where users was placed in more than one
3142 Organization Units. When I tried to give exim partial DN, the exit code
3143 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3144 But simultaneously result of request was absolutely normal ldap result,
3145 so I produce this patch..."
3146
3295e65b
PH
3147 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3148 REFERENCE, so I have modified the code to exclude the patch when that macro
3149 is not defined.

3152 keys for these records are domain names, not reversed IP addresses. The
b975ba52

3153 dnsdb PTR lookup now tests whether its key is an IP address. If not, it

317160. The host_aton() function is supposed to be passed a string that is known
3172 to be a valid IP address. However, in the case of IPv6 addresses, it was
3173 not checking this. This is a hostage to fortune. Exim now panics and dies
3174 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3175 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3176 components; fortuitously, this particular loophole had already been fixed
3177 by change 4.50/55 above.
3178
3179 If there are any other similar loopholes, the new check in host_aton()
3180 itself should stop them being exploited. The report I received stated that
3181 data on the command line could provoke the exploit when Exim was running as
3182 exim, but did not say which command line option was involved. All I could
3183 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3184 running as the user.

318761. There was a buffer overflow vulnerability in the SPA authentication code
3188 (which came originally from the Samba project). I have added a test to the
3189 spa_base64_to_bits() function which I hope fixes it.

319262. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3193 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3194

PH
319563. The daemon start-up calls getloadavg() while still root for those OS that
3196 need the first call to be done as root, but it missed one case: when
3197 deliver_queue_load_max is set with deliver_drop_privilege. This is
3198 necessary for the benefit of the queue runner, because there is no re-exec
3199 when deliver_drop_privilege is set.
3200

PH
320164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3202 This has been fixed.
3203
60dc5e56
PH
320465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3205 was in use, was not putting the data itself into the right store pool;
3206 consequently, it could be overwritten for a subsequent message in the same
3207 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3208 the caching.)
3209

PH
321066. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3211
a5a28604
PH
321267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3213 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3214 the function were treating the return as a boolean value, which happened to
3215 work because 0=false and not-0=true, but is not correct code.
3216
7e634d24
PH
321768. The host_aton() function was not handling scoped IPv6 addresses (those
3218 with, for example, "%eth0" on the end) correctly.
3219

PH
322069. Fixed some compiler warnings in acl.c for the bitmaps specified with
3221 negated items (that is, ~something) in unsigned ints. Some compilers
3222 apparently mutter when there is no cast.
3223
6729cf78
PH
322470. If an address verification called from an ACL failed, and did not produce a
3225 user-specific message (i.e. there was only a "system" message), nothing was
3226 put in $acl_verify_message. In this situation, it now puts the system
3227 message there.
3228
00f00ca5
PH
322971. Change 4.23/11 added synchronization checking at the start of an SMTP
3230 session; change 4.31/43 added the unwanted input to the log line - except
3231 that it did not do this in the start of session case. It now does.
3232
c9bdd01c
PH
323372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3234 This is wrong and can cause the other end to generate a synchronization
3235 error if it is another Exim or anything else that does the synchronization
3236 check. A QUIT command is no longer sent after a timeout.
3237

PH
323873. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3239 during host lookups.
3240

PH
324174. The defer_ok option of callout verification was not working if it was used
3242 when verifying addresses in header lines, that is, for this case:
3243
3244 verify = header_sender/callout=defer_ok
3245
76a2d7ba
PH
324675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3247 those file descriptors could be used for SMTP connections. If anything
3248 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3249 could be sent to the SMTP client, causing chaos. The daemon now opens
3250 stdin, stdout, and stderr to /dev/null when it puts itself into the
3251 background.
3252
325376. Arrange for output from Perl's "warn" command to be written to Exim's main
3254 log by default. The user can override this with suitable Perl magic.
3255
04f7d5b9
PH
325677. The use of log_message on a "discard" ACL verb, which is supposed to add to
3257 the log message when discard triggers, was not working for the DATA ACL or
3258 for the non-SMTP ACL.
3259
bc60667e
PH
326078. Error message wording change in sieve.c.
3261
bb6e88ff
PH
326279. If smtp_accept_max_per_host was set, the number of connections could be
3263 restricted to fewer than expected, because the daemon was trying to set up
3264 a new connection before checking whether the processes handling previous
3265 connections had finished. The check for completed processes is now done
3266 earlier. On busy systems, this bug wouldn't be noticed because something
3267 else would have woken the daemon, and it would have reaped the completed
3268 process earlier.
3269
1e70f85b
PH
327080. If a message was submitted locally by a user whose login name contained one
3271 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3272 It caused a spool format error. I have fixed the spool reading code. A
3273 related problem was that the "from" clause in the Received: line became
3274 illegal because of the space(s). It is now covered by ${quote_local_part.
3275
327681. Included the latest eximstats from Steve (adds average sizes to HTML Top
3277 tables).

3290----------------------------------------------------
3291See the note above about the 4.44 and 4.50 releases.
3292----------------------------------------------------
3293
3294
3295Exim version 4.44
3296-----------------
3297
3298 1. Change 4.43/35 introduced a bug that caused file counts to be
3299 incorrectly computed when quota_filecount was set in an appendfile
3300 transport
3301
3302 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3303 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3304 place.
3305
3306 3. Give more explanation in the error message when the command for a transport
3307 filter fails to execute.
3308
3309 4. There are several places where Exim runs a non-Exim command in a
3310 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3311 was being done only for the command run by the queryprogram router. It is
3312 now done for all such subprocesses. The other cases are: ${run, transport
3313 filters, and the commands run by the lmtp and pipe transports.
3314
3315 5. Some older OS have a limit of 256 on the maximum number of file
3316 descriptors. Exim was using setrlimit() to set 1000 as a large value
3317 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3318 systems. I've change it so that if it can't get 1000, it tries for 256.
3319
3320 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3321 was an oversight, and furthermore, ever since the addition of extra
3322 controls (e.g. 4.43/32), the checks on when to allow different forms of
3323 "control" were broken. There should now be diagnostics for all cases when a
3324 control that does not make sense is encountered.
3325
3326 7. $recipients is now available in the predata ACL (oversight).
3327
3328 8. Tidy the search cache before the fork to do a delivery from a message
3329 received from the command line. Otherwise the child will trigger a lookup
3330 failure and thereby defer the delivery if it tries to use (for example) a
3331 cached ldap connection that the parent has called unbind on.
3332
3333 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3334 of $address_data from the recipient verification was clobbered by the
3335 sender verification.
3336
333710. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3338 was its contents. (It was OK if the option was not defined at all.)
3339
334011. A "Completed" log line is now written for messages that are removed from
3341 the spool by the -Mrm option.
3342
334312. $host_address is now set to the target address during the checking of
3344 ignore_target_hosts.
3345
334613. When checking ignore_target_hosts for an ipliteral router, no host name was
3347 being passed; this would have caused $sender_host_name to have been used if
3348 matching the list had actually called for a host name (not very likely,
3349 since this list is usually IP addresses). A host name is now passed as
3350 "[x.x.x.x]".
3351
335214. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3353 code that specifies a non-restarting handler (typically sigaction() in
3354 modern systems) in an attempt to fix a rare and obscure crash bug.
3355
335615. Narrowed the window for a race in the daemon that could cause it to ignore
3357 SIGCHLD signals. This is not a major problem, because they are used only to
3358 wake it up if nothing else does.
3359
336016. A malformed maildirsize file could cause Exim to calculate negative values
3361 for the mailbox size or file count. Odd effects could occur as a result.
3362 The maildirsize information is now recalculated if the size or filecount
3363 end up negative.
3364
336517. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3366 support for a long time. Removed HAVE_SYS_VFS_H.
3367
ea3a6f44 336818. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3369
337019. Allow an empty sender to be matched against a lookup in an address list.
3371 Previously the only cases considered were a regular expression, or an
3372 empty pattern.
3373
337420. Exim went into a mad DNS lookup loop when doing a callout where the
3375 host was specified on the transport, if the DNS lookup yielded more than
3376 one IP address.
3377
ea3a6f44
NM
337821. The RFC2047 encoding function was originally intended for short strings
3379 such as real names; it was not keeping to the 75-character limit for
3380 encoded words that the RFC imposes. It now respects the limit, and
3381 generates multiple encoded words if necessary. To be on the safe side, I
3382 have increased the buffer size for the ${rfc2047: expansion operator from
3383 1024 to 2048 bytes.
bbe902f0 3384
ea3a6f44
NM
338522. Failure to deliver a bounce message always caused it to be frozen, even if
3386 there was an errors_to setting on the router. The errors_to setting is now
3387 respected.
bbe902f0
PH
3388
338923. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3390 canonical form (fully expanded) before being placed in
3391 $sender_host_address.
3392
339324. Updated eximstats to version 1.33
3394
ea3a6f44
NM
339525. Include certificate and key file names in error message when GnuTLS fails
3396 to set them up, because the GnuTLS error message doesn't include the name
3397 of the failing file when there is a problem reading it.
bbe902f0
PH
3398
339926. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3400 As per change 25.
bbe902f0 3401
ea3a6f44
NM
340227. Reset the locale to "C" after calling embedded Perl, in case it was changed
3403 (this can affect the format of dates).
bbe902f0 3404
ea3a6f44
NM
340528. exim_tidydb, when checking for the continued existence of a message for
3406 which it has found a message-specific retry record, was not finding
3407 messages that were in split spool directories. Consequently, it was
3408 deleting retry records that should have stayed in existence.
