TF
35TF/03 Make the exiwhat support code safe for signals. Previously Exim might
36 lock up or crash if it happened to be inside a call to libc when it
37 got a SIGUSR1 from exiwhat.
38
39 The SIGUSR1 handler appends the current process status to the process
40 log which is later printed by exiwhat. It used to use the general
41 purpose logging code to do this, but several functions it calls are
42 not safe for signals.
43
44 The new output code in the SIGUSR1 handler is specific to the process
45 log, and simple enough that it's easy to inspect for signal safety.
46 Removing some special cases also simplifies the general logging code.
47 Removing the spurious timestamps from the process log simplifies
48 exiwhat.

50TF/04 Improved ratelimit ACL condition.
51
52 The /noupdate option has been deprecated in favour of /readonly which
53 has clearer semantics. The /leaky, /strict, and /readonly update modes
54 are mutually exclusive. The update mode is no longer included in the
55 database key; it just determines when the database is updated. (This
56 means that when you upgrde Exim will forget old rate measurements.)
57
58 Exim now checks that the per_* options are used with an update mode that
59 makes sense for the current ACL. For example, when Exim is processing a
60 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
61 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
62 must specify per_mail/readonly. If you omit the update mode it defaults to
63 /leaky where that makes sense (as before) or /readonly where required.
64
65 The /noupdate option is now undocumented but still supported for
66 backwards compatibility. It is equivalent to /readonly except that in
67 ACLs where /readonly is required you may specify /leaky/noupdate or
68 /strict/noupdate which are treated the same as /readonly.
69
70 A useful new feature is the /count= option. This is a generalization
71 of the per_byte option, so that you can measure the throughput of other
72 aggregate values. For example, the per_byte option is now equivalent
73 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
74
75 The per_rcpt option has been generalized using the /count= mechanism
76 (though it's more complicated than the per_byte equivalence). When it is
77 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
78 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
79 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
80 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
81 Note that using per_rcpt with a non-readonly update mode in more than
82 one ACL will cause the recipients to be double-counted. (The per_mail
83 and per_byte options don't have this problem.)
84
85 The handling of very low rates has changed slightly. If the computed rate
86 is less than the event's count (usually one) then this event is the first
87 after a long gap. In this case the rate is set to the same as this event's
88 count, so that the first message of a spam run is counted properly.
89
90 The major new feature is a mechanism for counting the rate of unique
91 events. The new per_addr option counts the number of different
92 recipients that someone has sent messages to in the last time period. It
93 behaves like per_rcpt if all the recipient addresses are different, but
94 duplicate recipient addresses do not increase the measured rate. Like
95 the /count= option this is a general mechanism, so the per_addr option
96 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
97 example, measure the rate that a client uses different sender addresses
98 with the options per_mail/unique=$sender_address. There are further
99 details in the main documentation.

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

671PH/01 Another patch from the Sieve maintainer.
672
6a3bceb1
PH
673PH/02 When an IPv6 address is converted to a string for single-key lookup
674 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
675 dots are used instead of colons so that keys in lsearch files need not
676 contain colons. This was done some time before quoting was made available
677 in lsearch files. However, iplsearch files do require colons in IPv6 keys
678 (notated using the quote facility) so as to distinguish them from IPv4
679 keys. This meant that lookups for IP addresses in host lists did not work
680 for iplsearch lookups.
681
682 This has been fixed by arranging for IPv6 addresses to be expressed with
683 colons if the lookup type is iplsearch. This is not incompatible, because
684 previously such lookups could never work.
685
686 The situation is now rather anomolous, since one *can* have colons in
687 ordinary lsearch keys. However, making the change in all cases is
688 incompatible and would probably break a number of configurations.

693MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
694 conversion specification without a maximum field width, thereby enabling
695 a rogue spamd server to cause a buffer overflow. While nobody in their
696 right mind would setup Exim to query an untrusted spamd server, an
697 attacker that gains access to a server running spamd could potentially
698 exploit this vulnerability to run arbitrary code as the Exim user.

MH
703MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
704 a directory entry by the name of the lookup key. Previously, if a
705 symlink pointed to a non-existing file or a file in a directory that
706 Exim lacked permissions to read, a lookup for a key matching that
707 symlink would fail. Now it is enough that a matching directory entry
708 exists, symlink or not. (Bugzilla 503.)

PH
891PH/29 SMTP synchronization checks are implemented when a command is read -
892 there is a check that no more input is waiting when there shouldn't be
893 any. However, for some commands, a delay in an ACL can mean that it is
894 some time before the response is written. In this time, more input might
895 arrive, invalidly. So now there are extra checks after an ACL has run for
896 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
897 pipelining has not been advertised.

PH
971 the response to the final '.' that terminates a message, but only in the
972 case where the client has not sent further data following the '.'
973 (unfortunately, this is allowed). However, in many cases there won't be
974 any further data because there won't be any more messages to send. A call
975 to select() can be used: if it shows that the input is "ready", there is
976 either input waiting, or the socket has been closed. An attempt to read
977 the next input character can distinguish the two cases. Previously, Exim
58eb016e 978 would have sent an OK response which the client would never have see.

986Exim version 4.66
987-----------------
988
989PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
990 fixed by 4.65/MH/01 (is this a record?) are fixed:
991
992 (i) An empty string was always treated as zero by the numeric comparison
993 operators. This behaviour has been restored.
994
995 (ii) It is documented that the numeric comparison operators always treat
996 their arguments as decimal numbers. This was broken in that numbers
997 starting with 0 were being interpreted as octal.
998
999 While fixing these problems I realized that there was another issue that
1000 hadn't been noticed. Values of message_size_limit (both the global option
1001 and the transport option) were treated as octal if they started with 0.
1002 The documentation was vague. These values are now always treated as
1003 decimal, and I will make that clear in the documentation.

1018 child addresses, Exim now panics and dies. Previously, because the count
1019 is held in a short int, deliveries were likely to be lost. As such a
1020 large number of recipients for a single message is ridiculous
1021 (performance will be very, very poor), I have chosen to impose a limit
1022 rather than extend the field.

2b1c6e3a
PH
1047PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1048 callout verification, Exim cached a "reject" for the entire domain. This
1049 is correct for most verifications, but it is not correct for a recipient
1050 verification with use_sender or use_postmaster set, because in that case
1051 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1052 case of MAIL FROM:<> rejection from other early rejections (e.g.
1053 rejection of HELO). When verifying a recipient using a non-null MAIL
1054 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1055 Whatever the result of the callout, the value of the domain cache is
1056 left unchanged (for any other kind of callout, getting as far as trying
1057 RCPT means that the domain itself is ok).

1091PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1093 probably the interface on which it is arriving) and not to the outgoing
1094 callout (which could be using a different interface). This has been
1095 changed to use the value of the helo_data option from the smtp transport
1096 instead - this is what is used when a message is actually being sent. If
1097 there is no remote transport (possible with a router that sets up host
1098 addresses), $smtp_active_hostname is used.

7befa435 1101 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1102 (a) The code assumed that strncpy() returns a negative number on buffer
1103 overflow, which isn't the case. Replaced with Exim's string_format()
1104 function.
1105 (b) There were several signed/unsigned issues. I just did the minimum
1106 hacking in of casts. There is scope for a larger refactoring.
1107 (c) The code used strcasecmp() which is not a standard C function.
1108 Replaced with Exim's strcmpic() function.
1109 (d) The code set only $1; it now sets $auth1 as well.
1110 (e) A simple test gave the error "authentication client didn't specify
1111 service in request". It would seem that Dovecot has changed its
1112 interface. Fortunately there's a specification; I followed it and
1113 changed what the client sends and it appears to be working now.

1119 address A is aliased to B and C, where B exists and C does not. Without
1120 -v the output is "A verified" because verification stops after a
1121 successful redirection if more than one address is generated. However,
1122 with -v the child addresses are also verified. Exim was outputting "A
1123 failed to verify" and then showing the successful verification for C,
1124 with its parentage. It now outputs "B failed to verify", showing B's
1125 parentage before showing the successful verification of C.

1128 look up a TXT record in a specific list after matching in a combined

1130
322050c2
PH
1131PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1132 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1133 they consult the DNS. I had assumed they would set it the way they
1134 wanted; and indeed my experiments on Linux seem to show that in some
1135 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1136 To be on the safe side, however, I have now made the interface to
1137 host_find_byname() similar to host_find_bydns(), with an argument
1138 containing the DNS resolver options. The host_find_byname() function now
1139 sets these options at its start, just as host_find_bydns() does. The smtp
1140 transport options dns_qualify_single and dns_search_parents are passed to
1141 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1142 of host_find_byname() use the default settings of RES_DEFNAMES
1143 (qualify_single) but not RES_DNSRCH (search_parents).

1145PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1146 spool_read_header() do less string testing, by means of a preliminary
1147 switch on the second character of optional "-foo" lines. (This is
1148 overdue, caused by the large number of possibilities that now exist.
1149 Originally there were few.) While I was there, I also converted the
1150 str(n)cmp tests so they don't re-test the leading "-" and the first
1151 character, in the hope this might squeeze out yet more improvement.

1153PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1154 flag allowing group syntax was set by the header_syntax check but not
1155 turned off, possible causing trouble later; (2) The flag was not being
1156 set at all for the header_verify test, causing "group"-style headers to
1157 be rejected. I have now set it in this case, and also caused header_
1158 verify to ignore an empty address taken from a group. While doing this, I
1159 came across some other cases where the code for allowing group syntax
1160 while scanning a header line wasn't quite right (mostly, not resetting
1161 the flag correctly in the right place). These bugs could have caused
1162 trouble for malformed header lines. I hope it is now all correct.

PH
1164PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1165 with the "reply" argument non-NULL. The code, however (which originally
1166 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1167 but it didn't always do it. This confused somebody who was copying the
1168 code for some other use. I have removed all the tests.

PH
1170PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1171 feature that was used to support insecure browsers during the U.S. crypto
1172 embargo. It requires special client support, and Exim is probably the
1173 only MTA that supported it -- and would never use it because real RSA is
1174 always available. This code has been removed, because it had the bad
1175 effect of slowing Exim down by computing (never used) parameters for the
1176 RSA_EXPORT functionality.

1182 if the connection is using TLS or if the remote IP is the same as the
1183 local IP, and the "valid-client-cert option" if a client certificate has
1184 been verified.

1216PH/30 Exim was sometimes attempting to deliver messages that had suffered
1217 address errors (4xx response to RCPT) over the same connection as other
1218 messages routed to the same hosts. Such deliveries are always "forced",
1219 so retry times are not inspected. This resulted in far too many retries
1220 for the affected addresses. The effect occurred only when there were more
1221 hosts than the hosts_max_try setting in the smtp transport when it had
1222 the 4xx errors. Those hosts that it had tried were not added to the list
1223 of hosts for which the message was waiting, so if all were tried, there
1224 was no problem. Two fixes have been applied:
1225
1226 (i) If there are any address or message errors in an SMTP delivery, none
1227 of the hosts (tried or untried) are now added to the list of hosts
1228 for which the message is waiting, so the message should not be a
1229 candidate for sending over the same connection that was used for a
1230 successful delivery of some other message. This seems entirely
1231 reasonable: after all the message is NOT "waiting for some host".
1232 This is so "obvious" that I'm not sure why it wasn't done
1233 previously. Hope I haven't missed anything, but it can't do any
1234 harm, as the worst effect is to miss an optimization.
1235
1236 (ii) If, despite (i), such a delivery is accidentally attempted, the
1237 routing retry time is respected, so at least it doesn't keep
1238 hammering the server.

1253PH/35 The error "getsockname() failed: connection reset by peer" was being
1254 written to the panic log as well as the main log, but it isn't really
1255 panic-worthy as it just means the connection died rather early on. I have
1256 removed the panic log writing for the ECONNRESET error when getsockname()
1257 fails.
1258
48c7f9e2
PH
1259PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1260 runs only) independently of the message's sender address. This meant
1261 that, if the 4xx error was in fact related to the sender, a different
1262 message to the same recipient with a different sender could confuse
1263 things. In particualar, this can happen when sending to a greylisting
1264 server, but other circumstances could also provoke similar problems.
1265 I have changed the default so that the retry time for these errors is now
1266 based a combination of the sender and recipient addresses. This change
1267 can be overridden by setting address_retry_include_sender=false in the
1268 smtp transport.

1542 554 error is used if errno is still zero or contains ENOENT (which occurs

1595 lines in autoreplies, and the decoded form may well be syntactically
1596 invalid. However, $reply_address has leading white space removed, and all

1628 generate an autoreply, and therefore failed to obtain an address for the
1629 autoreply, Exim could try to deliver to a non-existent relative file
1630 name, causing unrelated and misleading errors. What now happens is that
1631 it logs this as a hard delivery error, but does not attempt to create a

1649 non-existent - all you got was a failure to exec. I have made two
1650 changes:
1651
1652 (a) Failures to set uid/gid, the current directory, or a process leader
1653 in a subprocess such as that created by queryprogram now generate
1654 suitable debugging ouput when -d is set.
1655

1658 the subprocess without attempting to change uid/gid.

1663PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1664 additional section of a DNS packet that returns MX or SRV records.
1665 Instead, it always explicitly searches for A/AAAA records. This avoids
1666 major problems that occur when a DNS server includes only records of one
1667 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1668 fixed another bug: if SRV records were looked up and the corresponding
1669 address records were *not* found in the additional section, the port
1670 values from the SRV records were lost.

PH
1680PH/19 When calculating a retry time, Exim used to measure the "time since
1681 failure" by looking at the "first failed" field in the retry record. Now
1682 it does not use this if it is later than than the arrival time of the
1683 message. Instead it uses the arrival time. This makes for better
1684 behaviour in cases where some deliveries succeed, thus re-setting the
1685 "first failed" field. An example is a quota failure for a huge message
1686 when small messages continue to be delivered. Without this change, the
1687 "time since failure" will always be short, possible causing more frequent
1688 delivery attempts for the huge message than are intended.

PH
1785PH/42 The content-scanning code uses fopen() to create files in which to put
1786 message data. Previously it was not paying any attention to the mode of
1787 the files. Exim runs with umask(0) because the rest of the code creates
1788 files with open(), and sets the required mode explicitly. Thus, these
1789 files were ending up world-writeable. This was not a big issue, because,
1790 being within the spool directory, they were not world-accessible. I have
1791 created a function called modefopen, which takes an additional mode
1792 argument. It sets umask(777), creates the file, chmods it to the required
1793 mode, then resets the umask. All the relevant calls to fopen() in the
1794 content scanning code have been changed to use this function.

1806 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

1831
1832 (i) Exim was not creating retry information for temporary errors given
1833 for individual recipients after the DATA command when the smtp transport
1834 was used in LMTP mode. This meant that they could be retried too
1835 frequently, and not timed out correctly.
1836
1837 (ii) Exim was setting the flag that allows error details to be returned
1838 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1839 recipients that were returned after the DATA command.
1840
1841PH/53 This is related to PH/52, but is more general: for any failing address,
1842 when detailed error information was permitted to be returned to the
1843 sender, but the error was temporary, then after the final timeout, only
1844 "retry timeout exceeded" was returned. Now it returns the full error as

1915PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1916 function verify_get_ident() calls ip_connect() to connect a socket, but
1917 if the "connect()" function timed out, ip_connect() used to close the
1918 socket. However, verify_get_ident() also closes the socket later, and in
1919 between Exim writes to the log, which may get opened at this point. When
1920 the socket was closed in ip_connect(), the log could get the same file
1921 descriptor number as the socket. This naturally causes chaos. The fix is
1922 not to close the socket in ip_connect(); the socket should be closed by
1923 the function that creates it. There was only one place in the code where
1924 this was missing, in the iplookup router, which I don't think anybody now
1925 uses, but I've fixed it anyway.

1984 IP address twice in Received: lines, even though the IP addresses were
1985 identical. For example:
1986
1987 Received: from [1.2.3.4] (helo=[1.2.3.4])
1988
1989 However, if the real host name was known, it was omitting the HELO data
1990 if it matched the actual IP address. This has been tidied up so that it
1991 doesn't show the same IP address twice.

2017PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2018 Electronic Mail") by including:
2019
2020 Auto-submitted: auto-generated
2021
2022 in the messages that it generates (bounce messages and others, such as
2023 warnings). In the case of bounce messages for non-SMTP mesages, there was
2024 also a typo: it was using "Auto_submitted" (underscore instead of
2025 hyphen). Since every message generated by Exim is necessarily in response
2026 to another message, thes have all been changed to:
2027
2028 Auto-Submitted: auto-replied
2029
2030 in accordance with these statements in the RFC:
2031
2032 The auto-replied keyword:
2033
2034 - SHOULD be used on messages sent in direct response to another
2035 message by an automatic process,
2036
2037 - MUST NOT be used on manually-generated messages,
2038
2039 - MAY be used on Delivery Status Notifications (DSNs) and Message
2040 Disposition Notifications (MDNs),

2080PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2081 canonical form (as documented). However, after a host name lookup from
2082 the IP address, check_host() was doing a simple string comparison with
2083 addresses acquired from the DNS when checking that the found name did
2084 have the original IP as one of its addresses. Since any found IPv6
2085 addresses are likely to be in abbreviated form, the comparison could
2086 fail. Luckily, there already exists a function for doing the comparison
2087 by converting both addresses to binary, so now that is used instead of
2088 the text comparison.

2090PH/20 There was another similar case to PH/19, when a complete host name was

2392PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2393 in the smtp transport. When a block could not be written in a single
2394 write() function, the timeout was being re-applied to each part-write.
2395 This seems wrong - if the receiver was accepting one byte at a time it
2396 would take for ever. The timeout is now adjusted when this happens. It
2397 doesn't have to be particularly precise.

2606PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2607 that changes the way the GnuTLS parameters are stored in the cache file.
2608 The new format can be generated externally. For backward compatibility,
2609 if the data in the cache doesn't make sense, Exim assumes it has read an
2610 old-format file, and it generates new data and writes a new file. This
2611 means that you can't go back to an older release without removing the
2612 file.
2613
2614PH/03 A redirect router that has both "unseen" and "one_time" set does not
2615 work if there are any delivery delays because "one_time" forces the
2616 parent to be marked "delivered", so its unseen clone is never tried
2617 again. For this reason, Exim now forbids the simultaneous setting of
2618 these two options.
2619
2620PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2621 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2622 entry if you want to know the details. The fix, however, neglected to
2623 consider the case when local delivery batching is involved. The test for
2624 "previously delivered" was not happening when checking to see if an
2625 address could be batched with a previous (undelivered) one; under
2626 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2627 address.

2632PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2633 header_syntax) but Exim was just ignoring anything given after a slash.
2634 In particular, this caused confusion with an attempt to use "verify =
2635 reverse_host_lookup/defer_ok". An error is now given when options are
2636 supplied for verify items that do not have them. (Maybe reverse_host_
2637 lookup should have a defer_ok option, but that's a different point.)

2639PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2692 the file with the wrong ownership). There was no test for failure of this
2693 fork() call, which would lead to the process getting stuck as it waited

2715PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

2717 understands it better than I do:
2718
2719 "Here's what I see happening with three configured cyrus_sasl
2720 authenticators configured (plain, login, cram-md5):
2721
2722 On startup auth_cyrus_sasl_init() gets called for each of these.
2723 This means three calls to sasl_listmech() without a specified mech_list.
2724 => SASL tests which mechs of all available mechs actually work
2725 => three warnings about OTP not working
2726 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2727
2728 With the patch, sasl_listmech() also gets called three times. But now
2729 SASL's mech_list option is set to the server_mech specified in the the
2730 authenticator. Or in other words, the answer from sasl_listmech()
2731 gets limited to just the mech you're testing for (which is different
2732 for each call.)
2733 => the return list contains just 'plain' or 'login', 'cram-md5' or
2734 nothing depending on the value of ob->server_mech.
2735
2736 I've just tested the patch: Authentication still works fine,

PH
2802PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2803 the grounds that routing the same address twice would always produce the
2804 same answer. This might have been true once, but it is certainly no
2805 longer true now. Routing a child address may depend on the previous
2806 routing that produced that child. Some complicated redirection strategies
2807 went wrong when messages had multiple recipients, and made Exim's
2808 behaviour dependent on the order in which the addresses were given.
2809
2810 I have moved the duplicate checking until after the routing is complete.
2811 Exim scans the addresses that are assigned to local and remote
2812 transports, and removes any duplicates. This means that more work will be
2813 done, as duplicates will always all be routed, but duplicates are
2814 presumably rare, so I don't expect this is of any significance.
2815
2816 For deliveries to pipes, files, and autoreplies, the duplicate checking
2817 still happens during the routing process, since they are not going to be
2818 routed further.

2823 connection it has accepted, or it never writes response data. The exiscan
2824 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2825 blindly assumes that writes won't block so it may never time out."

2847 (e) A message specified by the cannot_route_message router option.

2851 as "unrouteable address" or "local delivery error" are given.

2862 successful delivery. Such timeouts include transport filter timeouts. For
2863 consistency with the overall process timeout, these timeouts are now
2864 treated as errors, giving rise to delivery failures by default. However,
2865 there is now a new Boolean option for the pipe transport called
2866 timeout_defer, which, if set TRUE, converts the failures into defers for
2867 both kinds of timeout. A transport filter timeout is now identified in

2877A note about Exim versions 4.44 and 4.50
2878----------------------------------------
2879
2880Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2881changes of various kinds. As a consequence, a big documentation update was
2882needed. This delayed the release for rather longer than seemed good, especially
2883in the light of a couple of (minor) security issues. Therefore, the changes
2884that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2885release. So 4.44 and 4.50 are in effect two different branches that both start
2886from 4.43.
2887
2888I have left the 4.50 change log unchanged; it contains all the changes since
28894.43. The change log for 4.44 is below; many of its items are identical to
2890those for 4.50. This seems to be the most sensible way to preserve the
2891historical information.

2909 5. There are several places where Exim runs a non-Exim command in a
2910 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2911 was being done only for the command run by the queryprogram router. It is
2912 now done for all such subprocesses. The other cases are: ${run, transport
2913 filters, and the commands run by the lmtp and pipe transports.

2917 7. Some older OS have a limit of 256 on the maximum number of file
2918 descriptors. Exim was using setrlimit() to set 1000 as a large value
2919 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2920 systems. I've change it so that if it can't get 1000, it tries for 256.

2925 "control" were broken. There should now be diagnostics for all cases when a
2926 control that does not make sense is encountered.

296722. $host_address is now set to the target address during the checking of
2968 ignore_target_hosts.
2969
297023. When checking ignore_target_hosts for an ipliteral router, no host name was
2971 being passed; this would have caused $sender_host_name to have been used if
2972 matching the list had actually called for a host name (not very likely,
2973 since this list is usually IP addresses). A host name is now passed as
2974 "[x.x.x.x]".
2975
7d468ab8
PH
297624. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2977 code that specifies a non-restarting handler (typically sigaction() in
2978 modern systems) in an attempt to fix a rare and obscure crash bug.
2979
298025. Narrowed the window for a race in the daemon that could cause it to ignore
2981 SIGCHLD signals. This is not a major problem, because they are used only to
2982 wake it up if nothing else does.
2983
62c0818f
PH
298426. A malformed maildirsize file could cause Exim to calculate negative values
2985 for the mailbox size or file count. Odd effects could occur as a result.
2986 The maildirsize information is now recalculated if the size or filecount
2987 end up negative.
2988
26034054
PH

299228. Installed the latest version of exipick from John Jetmore.
2993
90af77f4
PH
299429. In an address list, if the pattern was not a regular expression, an empty
2995 subject address (from a bounce message) matched only if the pattern was an
2996 empty string. Non-empty patterns were not even tested. This was the wrong
2997 because it is perfectly reasonable to use an empty address as part of a
2998 database query. An empty address is now tested by patterns that are
2999 lookups. However, all the other forms of pattern expect the subject to
3000 contain a local part and a domain, and therefore, for them, an empty
3001 address still always fails if the pattern is not itself empty.
3002
d8ef3577
PH
300330. Exim went into a mad DNS loop when attempting to do a callout where the
3004 host was specified on an smtp transport, and looking it up yielded more
3005 than one IP address.
3006
5cb8cbc6
PH
300731. Re-factored the code for checking spool and log partition space into a
3008 function that finds that data and another that does the check. The former
3009 is then used to implement four new variables: $spool_space, $log_space,
3010 $spool_inodes, and $log_inodes.
3011
14702f5b
PH
301232. The RFC2047 encoding function was originally intended for short strings
3013 such as real names; it was not keeping to the 75-character limit for
3014 encoded words that the RFC imposes. It now respects the limit, and
3015 generates multiple encoded words if necessary. To be on the safe side, I
3016 have increased the buffer size for the ${rfc2047: expansion operator from
3017 1024 to 2048 bytes.
3018
063b1e99
PH
301933. It is now permitted to omit both strings after an "if" condition; if the
3020 condition is true, the result is "true". As before, when the second string
3021 is omitted, a false condition yields an empty string. This makes it less
3022 cumbersome to write custom ACL and router conditions.
3023
652e1b65
PH
302434. Failure to deliver a bounce message always caused it to be frozen, even if
3025 there was an errors_to setting on the router. The errors_to setting is now
3026 respected.
3027
6f0c9a4f
PH
302835. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3029 canonical form (fully expanded) before being placed in
3030 $sender_host_address.
3031
33397d19
PH
303236. The table in the code that translates DNS record types into text (T_A to
3033 "A" for instance) was missing entries for NS and CNAME. It is just possible
3034 that this could have caused confusion if both these types were looked up
3035 for the same domain, because the text type is used as part of Exim's
3036 per-process caching. But the chance of anyone hitting this buglet seems
3037 very small.
3038
7bb56e1f
PH
303937. The dnsdb lookup has been extended in a number of ways.
3040
3041 (1) There is a new type, "zns", which walks up the domain tree until it
3042 finds some nameserver records. It should be used with care.
3043
ea3bc19b
PH
3044 (2) There is a new type, "mxh", which is like "mx" except that it returns
3045 just the host names, not the priorities.
3046
3047 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19

3048 looked up. The behaviour when one of the lookups defers can be
3049 controlled by a keyword.
7bb56e1f 3050
ea3bc19b 3051 (4) It is now possible to specify the separator character for use when
7bb56e1f 3052 multiple records are returned.
33397d19 3053
0bcb2a0e
PH
305438. The dnslists ACL condition has been extended: it is now possible to supply

3056 domain.

PH
306341. Include certificate and key file names in error message when GnuTLS fails

3074 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3075 < 0 before doing a fflush(). This bug looks as though it goes back to the
3076 introduction of TLS in release 3.20, but "sometimes" must have been rare
3077 because the tests only now provoked it.

PH
310152. Exim crashed if a remote delivery caused a very long error message to be
3102 recorded - for instance if somebody sent an entire SpamAssassin report back
3103 as a large number of 550 error lines. This bug was coincidentally fixed by
3104 increasing the size of one of Exim's internal buffers (big_buffer) that
3105 happened as part of the Exiscan merge. However, to be on the safe side, I
3106 have made the code more robust (and fixed the comments that describe what
3107 is going on).

3112 the line.

PH
311454. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3115 patch that reportedly fixes this has been added. I am not expert enough to
3116 create a test for it. This is what the patch creator wrote:
3117
3118 "I found a little strange behaviour of ldap code when working with
3119 Windows 2003 AD Domain, where users was placed in more than one
3120 Organization Units. When I tried to give exim partial DN, the exit code
3121 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3122 But simultaneously result of request was absolutely normal ldap result,
3123 so I produce this patch..."
3124
3295e65b
PH
3125 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3126 REFERENCE, so I have modified the code to exclude the patch when that macro
3127 is not defined.

3130 keys for these records are domain names, not reversed IP addresses. The
b975ba52

3131 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3132 leaves it alone. Component reversal etc. now happens only for IP addresses.

3144

3146 (2) The default for smtp_banner uses $smtp_active_hostname instead
3147 of $primary_hostname.

b975ba52
PH
314960. The host_aton() function is supposed to be passed a string that is known
3150 to be a valid IP address. However, in the case of IPv6 addresses, it was
3151 not checking this. This is a hostage to fortune. Exim now panics and dies
3152 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3153 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3154 components; fortuitously, this particular loophole had already been fixed
3155 by change 4.50/55 above.
3156
3157 If there are any other similar loopholes, the new check in host_aton()
3158 itself should stop them being exploited. The report I received stated that
3159 data on the command line could provoke the exploit when Exim was running as
3160 exim, but did not say which command line option was involved. All I could
3161 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3162 running as the user.

317363. The daemon start-up calls getloadavg() while still root for those OS that
3174 need the first call to be done as root, but it missed one case: when
3175 deliver_queue_load_max is set with deliver_drop_privilege. This is
3176 necessary for the benefit of the queue runner, because there is no re-exec
3177 when deliver_drop_privilege is set.
3178

PH
317964. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3180 This has been fixed.
3181
60dc5e56
PH
318265. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3183 was in use, was not putting the data itself into the right store pool;
3184 consequently, it could be overwritten for a subsequent message in the same
3185 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3186 the caching.)
3187
533244af
PH
318866. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3189
a5a28604
PH
319067. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3191 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3192 the function were treating the return as a boolean value, which happened to
3193 work because 0=false and not-0=true, but is not correct code.
3194
7e634d24
PH
319568. The host_aton() function was not handling scoped IPv6 addresses (those
3196 with, for example, "%eth0" on the end) correctly.
3197
3e11c26b
PH
319869. Fixed some compiler warnings in acl.c for the bitmaps specified with
3199 negated items (that is, ~something) in unsigned ints. Some compilers
3200 apparently mutter when there is no cast.
3201
6729cf78
PH
320270. If an address verification called from an ACL failed, and did not produce a
3203 user-specific message (i.e. there was only a "system" message), nothing was
3204 put in $acl_verify_message. In this situation, it now puts the system
3205 message there.
3206
00f00ca5
PH
320771. Change 4.23/11 added synchronization checking at the start of an SMTP
3208 session; change 4.31/43 added the unwanted input to the log line - except
3209 that it did not do this in the start of session case. It now does.
3210
c9bdd01c
PH
321172. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3212 This is wrong and can cause the other end to generate a synchronization
3213 error if it is another Exim or anything else that does the synchronization
3214 check. A QUIT command is no longer sent after a timeout.
3215

PH
321673. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3217 during host lookups.
3218

PH
321974. The defer_ok option of callout verification was not working if it was used
3220 when verifying addresses in header lines, that is, for this case:
3221
3222 verify = header_sender/callout=defer_ok
3223
76a2d7ba
PH
322475. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3225 those file descriptors could be used for SMTP connections. If anything
3226 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3227 could be sent to the SMTP client, causing chaos. The daemon now opens
3228 stdin, stdout, and stderr to /dev/null when it puts itself into the
3229 background.
3230
323176. Arrange for output from Perl's "warn" command to be written to Exim's main
3232 log by default. The user can override this with suitable Perl magic.
3233
04f7d5b9
PH
323477. The use of log_message on a "discard" ACL verb, which is supposed to add to
3235 the log message when discard triggers, was not working for the DATA ACL or
3236 for the non-SMTP ACL.
3237
bc60667e
PH
323878. Error message wording change in sieve.c.
3239
bb6e88ff
PH
324079. If smtp_accept_max_per_host was set, the number of connections could be
3241 restricted to fewer than expected, because the daemon was trying to set up
3242 a new connection before checking whether the processes handling previous
3243 connections had finished. The check for completed processes is now done
3244 earlier. On busy systems, this bug wouldn't be noticed because something
3245 else would have woken the daemon, and it would have reaped the completed
3246 process earlier.
3247
1e70f85b
PH
324880. If a message was submitted locally by a user whose login name contained one
3249 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3250 It caused a spool format error. I have fixed the spool reading code. A
3251 related problem was that the "from" clause in the Received: line became
3252 illegal because of the space(s). It is now covered by ${quote_local_part.
3253
325481. Included the latest eximstats from Steve (adds average sizes to HTML Top
3255 tables).

3268----------------------------------------------------
3269See the note above about the 4.44 and 4.50 releases.
3270----------------------------------------------------
3271
3272
3273Exim version 4.44
3274-----------------
3275
3276 1. Change 4.43/35 introduced a bug that caused file counts to be
3277 incorrectly computed when quota_filecount was set in an appendfile
3278 transport
3279
3280 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3281 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3282 place.
3283
3284 3. Give more explanation in the error message when the command for a transport
3285 filter fails to execute.
3286
3287 4. There are several places where Exim runs a non-Exim command in a
3288 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3289 was being done only for the command run by the queryprogram router. It is
3290 now done for all such subprocesses. The other cases are: ${run, transport
3291 filters, and the commands run by the lmtp and pipe transports.
3292
3293 5. Some older OS have a limit of 256 on the maximum number of file
3294 descriptors. Exim was using setrlimit() to set 1000 as a large value
3295 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3296 systems. I've change it so that if it can't get 1000, it tries for 256.
3297
3298 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3299 was an oversight, and furthermore, ever since the addition of extra
3300 controls (e.g. 4.43/32), the checks on when to allow different forms of
3301 "control" were broken. There should now be diagnostics for all cases when a
3302 control that does not make sense is encountered.
3303
3304 7. $recipients is now available in the predata ACL (oversight).
3305
3306 8. Tidy the search cache before the fork to do a delivery from a message
3307 received from the command line. Otherwise the child will trigger a lookup
3308 failure and thereby defer the delivery if it tries to use (for example) a
3309 cached ldap connection that the parent has called unbind on.
3310
3311 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3312 of $address_data from the recipient verification was clobbered by the
3313 sender verification.
3314
331510. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3316 was its contents. (It was OK if the option was not defined at all.)
3317
331811. A "Completed" log line is now written for messages that are removed from
3319 the spool by the -Mrm option.
3320
332112. $host_address is now set to the target address during the checking of
3322 ignore_target_hosts.
3323
332413. When checking ignore_target_hosts for an ipliteral router, no host name was
3325 being passed; this would have caused $sender_host_name to have been used if
3326 matching the list had actually called for a host name (not very likely,
3327 since this list is usually IP addresses). A host name is now passed as
3328 "[x.x.x.x]".
3329
333014. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3331 code that specifies a non-restarting handler (typically sigaction() in
3332 modern systems) in an attempt to fix a rare and obscure crash bug.
3333
333415. Narrowed the window for a race in the daemon that could cause it to ignore
3335 SIGCHLD signals. This is not a major problem, because they are used only to
3336 wake it up if nothing else does.
3337
333816. A malformed maildirsize file could cause Exim to calculate negative values
3339 for the mailbox size or file count. Odd effects could occur as a result.
3340 The maildirsize information is now recalculated if the size or filecount
3341 end up negative.
3342
334317. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3344 support for a long time. Removed HAVE_SYS_VFS_H.
3345
ea3a6f44 334618. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3347
334819. Allow an empty sender to be matched against a lookup in an address list.
3349 Previously the only cases considered were a regular expression, or an
3350 empty pattern.
3351
335220. Exim went into a mad DNS lookup loop when doing a callout where the
3353 host was specified on the transport, if the DNS lookup yielded more than
3354 one IP address.
3355
ea3a6f44
NM
335621. The RFC2047 encoding function was originally intended for short strings
3357 such as real names; it was not keeping to the 75-character limit for
3358 encoded words that the RFC imposes. It now respects the limit, and
3359 generates multiple encoded words if necessary. To be on the safe side, I
3360 have increased the buffer size for the ${rfc2047: expansion operator from
3361 1024 to 2048 bytes.
bbe902f0 3362
ea3a6f44
NM
336322. Failure to deliver a bounce message always caused it to be frozen, even if
3364 there was an errors_to setting on the router. The errors_to setting is now
3365 respected.
bbe902f0
PH
3366
336723. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3368 canonical form (fully expanded) before being placed in
3369 $sender_host_address.
3370
337124. Updated eximstats to version 1.33
3372
ea3a6f44
NM
337325. Include certificate and key file names in error message when GnuTLS fails
3374 to set them up, because the GnuTLS error message doesn't include the name
3375 of the failing file when there is a problem reading it.
bbe902f0
PH
3376
337726. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3378 As per change 25.
bbe902f0 3379
ea3a6f44
NM
338027. Reset the locale to "C" after calling embedded Perl, in case it was changed
3381 (this can affect the format of dates).
bbe902f0 3382
ea3a6f44
NM
338328. exim_tidydb, when checking for the continued existence of a message for
3384 which it has found a message-specific retry record, was not finding
3385 messages that were in split spool directories. Consequently, it was
3386 deleting retry records that should have stayed in existence.
bbe902f0
PH
3387
338829. eximstats updated to version 1.35
3389 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3390 1.35 - bugfix such that pie charts by volume are generated correctly
3391
ea3a6f44
NM
339230. The SPA authentication driver was not abandoning authentication and moving
3393 on to the next authenticator when an expansion was forced to fail,
3394 contradicting the general specification for all authenticators. Instead it
3395 was generating a temporary error. It now behaves as specified.
bbe902f0 3396
ea3a6f44
NM
339731. The default ordering of permitted cipher suites for GnuTLS was pessimal
3398 (the order specifies the preference for clients). The order is now AES256,
3399 AES128, 3DES, ARCFOUR128.
bbe902f0 3400
ea3a6f44
NM
340131. Small patch to Sieve code - explicitly set From: when generating an
3402 autoreply.
bbe902f0 3403
ea3a6f44
NM
340432. Exim crashed if a remote delivery caused a very long error message to be
3405 recorded - for instance if somebody sent an entire SpamAssassin report back
3406 as a large number of 550 error lines. This bug was coincidentally fixed by
3407 increasing the size of one of Exim's internal buffers (big_buffer) that
3408 happened as part of the Exiscan merge. However, to be on the safe side, I
3409 have made the code more robust (and fixed the comments that describe what
3410 is going on).
