921b12ca
TF
91TF/03 Make the exiwhat support code safe for signals. Previously Exim might
92 lock up or crash if it happened to be inside a call to libc when it
93 got a SIGUSR1 from exiwhat.
94
95 The SIGUSR1 handler appends the current process status to the process
96 log which is later printed by exiwhat. It used to use the general
97 purpose logging code to do this, but several functions it calls are
98 not safe for signals.
99
100 The new output code in the SIGUSR1 handler is specific to the process
101 log, and simple enough that it's easy to inspect for signal safety.
102 Removing some special cases also simplifies the general logging code.
103 Removing the spurious timestamps from the process log simplifies
104 exiwhat.
105
c99ce5c9
TF
106TF/04 Improved ratelimit ACL condition.
107
108 The /noupdate option has been deprecated in favour of /readonly which
109 has clearer semantics. The /leaky, /strict, and /readonly update modes
110 are mutually exclusive. The update mode is no longer included in the
111 database key; it just determines when the database is updated. (This
112 means that when you upgrde Exim will forget old rate measurements.)
113
114 Exim now checks that the per_* options are used with an update mode that
115 makes sense for the current ACL. For example, when Exim is processing a
116 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
117 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
118 must specify per_mail/readonly. If you omit the update mode it defaults to
119 /leaky where that makes sense (as before) or /readonly where required.
120
121 The /noupdate option is now undocumented but still supported for
122 backwards compatibility. It is equivalent to /readonly except that in
123 ACLs where /readonly is required you may specify /leaky/noupdate or
124 /strict/noupdate which are treated the same as /readonly.
125
126 A useful new feature is the /count= option. This is a generalization
127 of the per_byte option, so that you can measure the throughput of other
128 aggregate values. For example, the per_byte option is now equivalent
129 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
130
131 The per_rcpt option has been generalized using the /count= mechanism
132 (though it's more complicated than the per_byte equivalence). When it is
133 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
134 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
135 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
136 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
137 Note that using per_rcpt with a non-readonly update mode in more than
138 one ACL will cause the recipients to be double-counted. (The per_mail
139 and per_byte options don't have this problem.)
140
141 The handling of very low rates has changed slightly. If the computed rate
142 is less than the event's count (usually one) then this event is the first
143 after a long gap. In this case the rate is set to the same as this event's
144 count, so that the first message of a spam run is counted properly.
145
146 The major new feature is a mechanism for counting the rate of unique
147 events. The new per_addr option counts the number of different
148 recipients that someone has sent messages to in the last time period. It
149 behaves like per_rcpt if all the recipient addresses are different, but
150 duplicate recipient addresses do not increase the measured rate. Like
151 the /count= option this is a general mechanism, so the per_addr option
152 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
153 example, measure the rate that a client uses different sender addresses
154 with the options per_mail/unique=$sender_address. There are further
155 details in the main documentation.

6a3bceb1
PH
729PH/02 When an IPv6 address is converted to a string for single-key lookup
730 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
731 dots are used instead of colons so that keys in lsearch files need not
732 contain colons. This was done some time before quoting was made available
733 in lsearch files. However, iplsearch files do require colons in IPv6 keys
734 (notated using the quote facility) so as to distinguish them from IPv4
735 keys. This meant that lookups for IP addresses in host lists did not work
736 for iplsearch lookups.
737
738 This has been fixed by arranging for IPv6 addresses to be expressed with
739 colons if the lookup type is iplsearch. This is not incompatible, because
740 previously such lookups could never work.
741
742 The situation is now rather anomolous, since one *can* have colons in
743 ordinary lsearch keys. However, making the change in all cases is
744 incompatible and would probably break a number of configurations.

749MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
750 conversion specification without a maximum field width, thereby enabling
751 a rogue spamd server to cause a buffer overflow. While nobody in their
752 right mind would setup Exim to query an untrusted spamd server, an
753 attacker that gains access to a server running spamd could potentially
754 exploit this vulnerability to run arbitrary code as the Exim user.

759MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
760 a directory entry by the name of the lookup key. Previously, if a
761 symlink pointed to a non-existing file or a file in a directory that
762 Exim lacked permissions to read, a lookup for a key matching that
763 symlink would fail. Now it is enough that a matching directory entry
764 exists, symlink or not. (Bugzilla 503.)

947PH/29 SMTP synchronization checks are implemented when a command is read -
948 there is a check that no more input is waiting when there shouldn't be

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

1027 the response to the final '.' that terminates a message, but only in the
1028 case where the client has not sent further data following the '.'
1029 (unfortunately, this is allowed). However, in many cases there won't be
1030 any further data because there won't be any more messages to send. A call
1031 to select() can be used: if it shows that the input is "ready", there is
1032 either input waiting, or the socket has been closed. An attempt to read
1033 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1034 would have sent an OK response which the client would never have see.

1045PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1046 fixed by 4.65/MH/01 (is this a record?) are fixed:
1047
1048 (i) An empty string was always treated as zero by the numeric comparison
1049 operators. This behaviour has been restored.
1050
1051 (ii) It is documented that the numeric comparison operators always treat
1052 their arguments as decimal numbers. This was broken in that numbers
1053 starting with 0 were being interpreted as octal.
1054
1055 While fixing these problems I realized that there was another issue that
1056 hadn't been noticed. Values of message_size_limit (both the global option
1057 and the transport option) were treated as octal if they started with 0.
1058 The documentation was vague. These values are now always treated as
1059 decimal, and I will make that clear in the documentation.

1076 large number of recipients for a single message is ridiculous
1077 (performance will be very, very poor), I have chosen to impose a limit

PH
1103PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1104 callout verification, Exim cached a "reject" for the entire domain. This
1105 is correct for most verifications, but it is not correct for a recipient
1106 verification with use_sender or use_postmaster set, because in that case
1107 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1108 case of MAIL FROM:<> rejection from other early rejections (e.g.
1109 rejection of HELO). When verifying a recipient using a non-null MAIL
1110 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1111 Whatever the result of the callout, the value of the domain cache is
1112 left unchanged (for any other kind of callout, getting as far as trying
1113 RCPT means that the domain itself is ok).

1149 probably the interface on which it is arriving) and not to the outgoing
1150 callout (which could be using a different interface). This has been
1151 changed to use the value of the helo_data option from the smtp transport
1152 instead - this is what is used when a message is actually being sent. If
1153 there is no remote transport (possible with a router that sets up host
1154 addresses), $smtp_active_hostname is used.

7befa435 1157 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1158 (a) The code assumed that strncpy() returns a negative number on buffer
1159 overflow, which isn't the case. Replaced with Exim's string_format()
1160 function.
1161 (b) There were several signed/unsigned issues. I just did the minimum
1162 hacking in of casts. There is scope for a larger refactoring.
1163 (c) The code used strcasecmp() which is not a standard C function.
1164 Replaced with Exim's strcmpic() function.
1165 (d) The code set only $1; it now sets $auth1 as well.
1166 (e) A simple test gave the error "authentication client didn't specify
1167 service in request". It would seem that Dovecot has changed its
1168 interface. Fortunately there's a specification; I followed it and
1169 changed what the client sends and it appears to be working now.

1176 -v the output is "A verified" because verification stops after a
1177 successful redirection if more than one address is generated. However,
1178 with -v the child addresses are also verified. Exim was outputting "A
1179 failed to verify" and then showing the successful verification for C,
1180 with its parentage. It now outputs "B failed to verify", showing B's
1181 parentage before showing the successful verification of C.

PH
1187PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1188 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1189 they consult the DNS. I had assumed they would set it the way they
1190 wanted; and indeed my experiments on Linux seem to show that in some
1191 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1192 To be on the safe side, however, I have now made the interface to
1193 host_find_byname() similar to host_find_bydns(), with an argument
1194 containing the DNS resolver options. The host_find_byname() function now
1195 sets these options at its start, just as host_find_bydns() does. The smtp
1196 transport options dns_qualify_single and dns_search_parents are passed to
1197 host_find_byname() when gethostbyname=TRUE in this transport. Other uses

1201PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1202 spool_read_header() do less string testing, by means of a preliminary
1203 switch on the second character of optional "-foo" lines. (This is
1204 overdue, caused by the large number of possibilities that now exist.
1205 Originally there were few.) While I was there, I also converted the
1206 str(n)cmp tests so they don't re-test the leading "-" and the first
1207 character, in the hope this might squeeze out yet more improvement.

1209PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1210 flag allowing group syntax was set by the header_syntax check but not
1211 turned off, possible causing trouble later; (2) The flag was not being
1212 set at all for the header_verify test, causing "group"-style headers to
1213 be rejected. I have now set it in this case, and also caused header_
1214 verify to ignore an empty address taken from a group. While doing this, I
1215 came across some other cases where the code for allowing group syntax
1216 while scanning a header line wasn't quite right (mostly, not resetting
1217 the flag correctly in the right place). These bugs could have caused
1218 trouble for malformed header lines. I hope it is now all correct.

1220PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1221 with the "reply" argument non-NULL. The code, however (which originally
1222 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1223 but it didn't always do it. This confused somebody who was copying the
1224 code for some other use. I have removed all the tests.

PH
1226PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1227 feature that was used to support insecure browsers during the U.S. crypto
1228 embargo. It requires special client support, and Exim is probably the
1229 only MTA that supported it -- and would never use it because real RSA is
1230 always available. This code has been removed, because it had the bad
1231 effect of slowing Exim down by computing (never used) parameters for the
1232 RSA_EXPORT functionality.

PH
1234PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1235 authenticator to fail if there's a tab character in the incoming data

1237 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1238 if the connection is using TLS or if the remote IP is the same as the
1239 local IP, and the "valid-client-cert option" if a client certificate has
1240 been verified.

1271
1272PH/30 Exim was sometimes attempting to deliver messages that had suffered
1273 address errors (4xx response to RCPT) over the same connection as other
1274 messages routed to the same hosts. Such deliveries are always "forced",
1275 so retry times are not inspected. This resulted in far too many retries
1276 for the affected addresses. The effect occurred only when there were more
1277 hosts than the hosts_max_try setting in the smtp transport when it had
1278 the 4xx errors. Those hosts that it had tried were not added to the list
1279 of hosts for which the message was waiting, so if all were tried, there
1280 was no problem. Two fixes have been applied:
1281
1282 (i) If there are any address or message errors in an SMTP delivery, none
1283 of the hosts (tried or untried) are now added to the list of hosts
1284 for which the message is waiting, so the message should not be a
1285 candidate for sending over the same connection that was used for a
1286 successful delivery of some other message. This seems entirely
1287 reasonable: after all the message is NOT "waiting for some host".
1288 This is so "obvious" that I'm not sure why it wasn't done
1289 previously. Hope I haven't missed anything, but it can't do any
1290 harm, as the worst effect is to miss an optimization.
1291
1292 (ii) If, despite (i), such a delivery is accidentally attempted, the
1293 routing retry time is respected, so at least it doesn't keep
1294 hammering the server.

1309PH/35 The error "getsockname() failed: connection reset by peer" was being
1310 written to the panic log as well as the main log, but it isn't really
1311 panic-worthy as it just means the connection died rather early on. I have
1312 removed the panic log writing for the ECONNRESET error when getsockname()
1313 fails.
1314
48c7f9e2
PH
1315PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1316 runs only) independently of the message's sender address. This meant
1317 that, if the 4xx error was in fact related to the sender, a different
1318 message to the same recipient with a different sender could confuse
1319 things. In particualar, this can happen when sending to a greylisting
1320 server, but other circumstances could also provoke similar problems.
1321 I have changed the default so that the retry time for these errors is now
1322 based a combination of the sender and recipient addresses. This change
1323 can be overridden by setting address_retry_include_sender=false in the
1324 smtp transport.

1592PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1593 "Deny" causes Exim to reject the incoming connection with a 554 error.
1594 Unfortunately, if there is a major crisis, such as a disk failure,
1595 tcp-wrappers gives "deny", whereas what one would like would be some
1596 kind of temporary error. A kludge has been added to help with this.
1597 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1598 554 error is used if errno is still zero or contains ENOENT (which occurs
1599 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1600 451 error is used.

1622PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1623 folder from quota calculations, a direct delivery into this folder messed
1624 up the contents of the maildirsize file. This was because the regex was
1625 used only to exclude .Trash (or whatever) when the size of the mailbox
1626 was calculated. There was no check that a delivery was happening into an
1627 excluded directory. This bug has been fixed by ignoring all quota

1636PH/01 The code for finding all the local interface addresses on a FreeBSD
1637 system running IPv6 was broken. This may well have applied to all BSD
1638 systems, as well as to others that have similar system calls. The broken
1639 code found IPv4 interfaces correctly, but gave incorrect values for the
1640 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1641 that it would not match correctly against @[] and not recognize the IPv6
1642 addresses as local.

1684 generate an autoreply, and therefore failed to obtain an address for the
1685 autoreply, Exim could try to deliver to a non-existent relative file
1686 name, causing unrelated and misleading errors. What now happens is that
1687 it logs this as a hard delivery error, but does not attempt to create a

1707
1708 (a) Failures to set uid/gid, the current directory, or a process leader
1709 in a subprocess such as that created by queryprogram now generate
1710 suitable debugging ouput when -d is set.

1719PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1720 additional section of a DNS packet that returns MX or SRV records.
1721 Instead, it always explicitly searches for A/AAAA records. This avoids
1722 major problems that occur when a DNS server includes only records of one
1723 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1724 fixed another bug: if SRV records were looked up and the corresponding
1725 address records were *not* found in the additional section, the port
1726 values from the SRV records were lost.

1728PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1736PH/19 When calculating a retry time, Exim used to measure the "time since
1737 failure" by looking at the "first failed" field in the retry record. Now
1738 it does not use this if it is later than than the arrival time of the
1739 message. Instead it uses the arrival time. This makes for better
1740 behaviour in cases where some deliveries succeed, thus re-setting the
1741 "first failed" field. An example is a quota failure for a huge message
1742 when small messages continue to be delivered. Without this change, the
1743 "time since failure" will always be short, possible causing more frequent
1744 delivery attempts for the huge message than are intended.

PH
1841PH/42 The content-scanning code uses fopen() to create files in which to put
1842 message data. Previously it was not paying any attention to the mode of
1843 the files. Exim runs with umask(0) because the rest of the code creates
1844 files with open(), and sets the required mode explicitly. Thus, these
1845 files were ending up world-writeable. This was not a big issue, because,
1846 being within the spool directory, they were not world-accessible. I have
1847 created a function called modefopen, which takes an additional mode
1848 argument. It sets umask(777), creates the file, chmods it to the required
1849 mode, then resets the umask. All the relevant calls to fopen() in the
1850 content scanning code have been changed to use this function.

1887
1888 (i) Exim was not creating retry information for temporary errors given
1889 for individual recipients after the DATA command when the smtp transport
1890 was used in LMTP mode. This meant that they could be retried too
1891 frequently, and not timed out correctly.
1892
1893 (ii) Exim was setting the flag that allows error details to be returned
1894 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1895 recipients that were returned after the DATA command.
1896
1897PH/53 This is related to PH/52, but is more general: for any failing address,
1898 when detailed error information was permitted to be returned to the

1974 socket. However, verify_get_ident() also closes the socket later, and in
1975 between Exim writes to the log, which may get opened at this point. When
1976 the socket was closed in ip_connect(), the log could get the same file
1977 descriptor number as the socket. This naturally causes chaos. The fix is
1978 not to close the socket in ip_connect(); the socket should be closed by
1979 the function that creates it. There was only one place in the code where
1980 this was missing, in the iplookup router, which I don't think anybody now
1981 uses, but I've fixed it anyway.

2000PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2001
2002 (1) Generate an error if the third argument for the ${prvs expansion is
2003 not a single digit.
2004
2005 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2006 string.
2007
2008 (3) Reset the variables that are obtained from the first argument of
2009 ${prvscheck and used in the second argument before leaving the code,
2010 because their memory is reclaimed, so using them afterwards may do
2011 silly things.
2012
2013 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2014 one (it's much easier than Tom thought :-).
2015
2016 (5) Because of (4), we can now allow for the use of $prvscheck_result
2017 inside the third argument.

2032 may be more than one such address. If so, they are comma-separated, like

2037PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2038 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2039 not being looked up in the rDNS to get a host name, Exim was showing the
2040 IP address twice in Received: lines, even though the IP addresses were
2041 identical. For example:
2042
2043 Received: from [1.2.3.4] (helo=[1.2.3.4])
2044
2045 However, if the real host name was known, it was omitting the HELO data
2046 if it matched the actual IP address. This has been tidied up so that it
2047 doesn't show the same IP address twice.

2073PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2075
2076 Auto-submitted: auto-generated
2077
2078 in the messages that it generates (bounce messages and others, such as
2079 warnings). In the case of bounce messages for non-SMTP mesages, there was
2080 also a typo: it was using "Auto_submitted" (underscore instead of
2081 hyphen). Since every message generated by Exim is necessarily in response
2082 to another message, thes have all been changed to:
2083
2084 Auto-Submitted: auto-replied
2085
2086 in accordance with these statements in the RFC:
2087
2088 The auto-replied keyword:
2089
2090 - SHOULD be used on messages sent in direct response to another
2091 message by an automatic process,
2092
2093 - MUST NOT be used on manually-generated messages,
2094
2095 - MAY be used on Delivery Status Notifications (DSNs) and Message
2096 Disposition Notifications (MDNs),

2136PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2137 canonical form (as documented). However, after a host name lookup from
2138 the IP address, check_host() was doing a simple string comparison with
2139 addresses acquired from the DNS when checking that the found name did
2140 have the original IP as one of its addresses. Since any found IPv6
2141 addresses are likely to be in abbreviated form, the comparison could
2142 fail. Luckily, there already exists a function for doing the comparison
2143 by converting both addresses to binary, so now that is used instead of
2144 the text comparison.

2441PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2442 with the definition in sysexits.h (which is #included earlier).
2443 Fortunately, Exim does not actually use EX_OK. The code used to try to
2444 preserve the sysexits.h value, by assumimg that macro definitions were
2445 scanned for macro replacements. I have been disabused of this notion,
2446 so now the code just undefines EX_OK before #including unistd.h.

2451 This seems wrong - if the receiver was accepting one byte at a time it
2452 would take for ever. The timeout is now adjusted when this happens. It
2453 doesn't have to be particularly precise.

2529 case the guess is not the same as the compiled default, so the script
2530 suddenly stopped working when I started to use syslog. The patch checks
2531 to see if log_file_path is "". If so, it attempts to read it from exim

2661
2662PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2663 that changes the way the GnuTLS parameters are stored in the cache file.
2664 The new format can be generated externally. For backward compatibility,
2665 if the data in the cache doesn't make sense, Exim assumes it has read an
2666 old-format file, and it generates new data and writes a new file. This
2667 means that you can't go back to an older release without removing the
2668 file.
2669
2670PH/03 A redirect router that has both "unseen" and "one_time" set does not
2671 work if there are any delivery delays because "one_time" forces the
2672 parent to be marked "delivered", so its unseen clone is never tried
2673 again. For this reason, Exim now forbids the simultaneous setting of
2674 these two options.
2675
2676PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2677 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2678 entry if you want to know the details. The fix, however, neglected to
2679 consider the case when local delivery batching is involved. The test for
2680 "previously delivered" was not happening when checking to see if an
2681 address could be batched with a previous (undelivered) one; under
2682 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2683 address.

PH
2684
2685PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2688PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2689 header_syntax) but Exim was just ignoring anything given after a slash.
2690 In particular, this caused confusion with an attempt to use "verify =
2691 reverse_host_lookup/defer_ok". An error is now given when options are
2692 supplied for verify items that do not have them. (Maybe reverse_host_
2693 lookup should have a defer_ok option, but that's a different point.)
2694
2695PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2748 the file with the wrong ownership). There was no test for failure of this
2749 fork() call, which would lead to the process getting stuck as it waited
2750 for a non-existent subprocess. Forks do occasionally fail when resources

2777
2778 On startup auth_cyrus_sasl_init() gets called for each of these.
2779 This means three calls to sasl_listmech() without a specified mech_list.
2780 => SASL tests which mechs of all available mechs actually work
2781 => three warnings about OTP not working
2782 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2783
2784 With the patch, sasl_listmech() also gets called three times. But now
2785 SASL's mech_list option is set to the server_mech specified in the the
2786 authenticator. Or in other words, the answer from sasl_listmech()
2787 gets limited to just the mech you're testing for (which is different
2788 for each call.)
2789 => the return list contains just 'plain' or 'login', 'cram-md5' or
2790 nothing depending on the value of ob->server_mech.

PH
2858PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2859 the grounds that routing the same address twice would always produce the
2860 same answer. This might have been true once, but it is certainly no
2861 longer true now. Routing a child address may depend on the previous
2862 routing that produced that child. Some complicated redirection strategies
2863 went wrong when messages had multiple recipients, and made Exim's
2864 behaviour dependent on the order in which the addresses were given.
2865
2866 I have moved the duplicate checking until after the routing is complete.
2867 Exim scans the addresses that are assigned to local and remote
2868 transports, and removes any duplicates. This means that more work will be
2869 done, as duplicates will always all be routed, but duplicates are
2870 presumably rare, so I don't expect this is of any significance.
2871
2872 For deliveries to pipes, files, and autoreplies, the duplicate checking
2873 still happens during the routing process, since they are not going to be
2874 routed further.

2919 consistency with the overall process timeout, these timeouts are now
2920 treated as errors, giving rise to delivery failures by default. However,
2921 there is now a new Boolean option for the pipe transport called
2922 timeout_defer, which, if set TRUE, converts the failures into defers for
2923 both kinds of timeout. A transport filter timeout is now identified in

2933A note about Exim versions 4.44 and 4.50
2934----------------------------------------
2935
2936Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2937changes of various kinds. As a consequence, a big documentation update was
2938needed. This delayed the release for rather longer than seemed good, especially
2939in the light of a couple of (minor) security issues. Therefore, the changes
2940that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2941release. So 4.44 and 4.50 are in effect two different branches that both start
2942from 4.43.
2943
2944I have left the 4.50 change log unchanged; it contains all the changes since
29454.43. The change log for 4.44 is below; many of its items are identical to
2946those for 4.50. This seems to be the most sensible way to preserve the
2947historical information.

2965 5. There are several places where Exim runs a non-Exim command in a
2966 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2967 was being done only for the command run by the queryprogram router. It is
2968 now done for all such subprocesses. The other cases are: ${run, transport
2969 filters, and the commands run by the lmtp and pipe transports.

2974 descriptors. Exim was using setrlimit() to set 1000 as a large value
2975 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2976 systems. I've change it so that if it can't get 1000, it tries for 256.

3024 ignore_target_hosts.
3025
302623. When checking ignore_target_hosts for an ipliteral router, no host name was
3027 being passed; this would have caused $sender_host_name to have been used if
3028 matching the list had actually called for a host name (not very likely,
3029 since this list is usually IP addresses). A host name is now passed as
3030 "[x.x.x.x]".

PH
303224. Changed the calls that set up the SIGCHLD handler in the daemon to use the

3034 modern systems) in an attempt to fix a rare and obscure crash bug.
3035
303625. Narrowed the window for a race in the daemon that could cause it to ignore

305029. In an address list, if the pattern was not a regular expression, an empty
3051 subject address (from a bounce message) matched only if the pattern was an
3052 empty string. Non-empty patterns were not even tested. This was the wrong
3053 because it is perfectly reasonable to use an empty address as part of a
3054 database query. An empty address is now tested by patterns that are
3055 lookups. However, all the other forms of pattern expect the subject to
3056 contain a local part and a domain, and therefore, for them, an empty
3057 address still always fails if the pattern is not itself empty.
3058

PH
305930. Exim went into a mad DNS loop when attempting to do a callout where the
3060 host was specified on an smtp transport, and looking it up yielded more
3061 than one IP address.

PH
306331. Re-factored the code for checking spool and log partition space into a
3064 function that finds that data and another that does the check. The former

3066 $spool_inodes, and $log_inodes.
3067

PH
306832. The RFC2047 encoding function was originally intended for short strings
3069 such as real names; it was not keeping to the 75-character limit for
3070 encoded words that the RFC imposes. It now respects the limit, and
3071 generates multiple encoded words if necessary. To be on the safe side, I
3072 have increased the buffer size for the ${rfc2047: expansion operator from
3073 1024 to 2048 bytes.
3074
063b1e99
PH
307533. It is now permitted to omit both strings after an "if" condition; if the
3076 condition is true, the result is "true". As before, when the second string
3077 is omitted, a false condition yields an empty string. This makes it less
3078 cumbersome to write custom ACL and router conditions.
3079
652e1b65
PH
308034. Failure to deliver a bounce message always caused it to be frozen, even if
3081 there was an errors_to setting on the router. The errors_to setting is now
3082 respected.

PH
308836. The table in the code that translates DNS record types into text (T_A to
3089 "A" for instance) was missing entries for NS and CNAME. It is just possible
3090 that this could have caused confusion if both these types were looked up
3091 for the same domain, because the text type is used as part of Exim's
3092 per-process caching. But the chance of anyone hitting this buglet seems
3093 very small.

PH
309537. The dnsdb lookup has been extended in a number of ways.

3160 increasing the size of one of Exim's internal buffers (big_buffer) that
3161 happened as part of the Exiscan merge. However, to be on the safe side, I
3162 have made the code more robust (and fixed the comments that describe what

3173
3174 "I found a little strange behaviour of ldap code when working with
3175 Windows 2003 AD Domain, where users was placed in more than one
3176 Organization Units. When I tried to give exim partial DN, the exit code
3177 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3178 But simultaneously result of request was absolutely normal ldap result,
3179 so I produce this patch..."
3180
3295e65b
PH
3181 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3182 REFERENCE, so I have modified the code to exclude the patch when that macro
3183 is not defined.
3184

PH
318555. Some experimental protocols are using DNS PTR records for new purposes. The
3186 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3187 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3188 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
319156. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.
3192
c2bcbe20
PH
319357. Double the size of the debug message buffer (to 2048) so that more of very
3194 long debug lines gets shown.
3195
18ce445d
PH
319658. The exicyclog utility now does better if the number of log files to keep
3197 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3198
1f5b4c3d
PH
319959. Two changes related to the smtp_active_hostname option:
3200
3201 (1) $smtp_active_hostname is now available as a variable.
3202 (2) The default for smtp_banner uses $smtp_active_hostname instead
3203 of $primary_hostname.
3204
b975ba52
PH
320560. The host_aton() function is supposed to be passed a string that is known
3206 to be a valid IP address. However, in the case of IPv6 addresses, it was
3207 not checking this. This is a hostage to fortune. Exim now panics and dies
3208 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3209 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3210 components; fortuitously, this particular loophole had already been fixed
3211 by change 4.50/55 above.
3212
3213 If there are any other similar loopholes, the new check in host_aton()
3214 itself should stop them being exploited. The report I received stated that
3215 data on the command line could provoke the exploit when Exim was running as
3216 exim, but did not say which command line option was involved. All I could
3217 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3218 running as the user.

3220
322161. There was a buffer overflow vulnerability in the SPA authentication code
3222 (which came originally from the Samba project). I have added a test to the
3223 spa_base64_to_bits() function which I hope fixes it.
ea3a6f44 3224 CAN-2005-0022

PH
322662. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3227 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3228
d95f9fdb
PH
322963. The daemon start-up calls getloadavg() while still root for those OS that
3230 need the first call to be done as root, but it missed one case: when
3231 deliver_queue_load_max is set with deliver_drop_privilege. This is
3232 necessary for the benefit of the queue runner, because there is no re-exec
3233 when deliver_drop_privilege is set.
3234
86b8287f
PH
323564. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3236 This has been fixed.
3237
60dc5e56
PH
323865. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3239 was in use, was not putting the data itself into the right store pool;
3240 consequently, it could be overwritten for a subsequent message in the same
3241 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3242 the caching.)
3243
533244af
PH
324466. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3245
a5a28604
PH
324667. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3247 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3248 the function were treating the return as a boolean value, which happened to
3249 work because 0=false and not-0=true, but is not correct code.
3250
7e634d24
PH
325168. The host_aton() function was not handling scoped IPv6 addresses (those
3252 with, for example, "%eth0" on the end) correctly.
3253
3e11c26b
PH
325469. Fixed some compiler warnings in acl.c for the bitmaps specified with
3255 negated items (that is, ~something) in unsigned ints. Some compilers
3256 apparently mutter when there is no cast.
3257
6729cf78
PH
325870. If an address verification called from an ACL failed, and did not produce a
3259 user-specific message (i.e. there was only a "system" message), nothing was
3260 put in $acl_verify_message. In this situation, it now puts the system
3261 message there.
3262
00f00ca5
PH
326371. Change 4.23/11 added synchronization checking at the start of an SMTP
3264 session; change 4.31/43 added the unwanted input to the log line - except
3265 that it did not do this in the start of session case. It now does.
3266
c9bdd01c
PH
326772. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3268 This is wrong and can cause the other end to generate a synchronization
3269 error if it is another Exim or anything else that does the synchronization
3270 check. A QUIT command is no longer sent after a timeout.
3271
d43194df
PH
327273. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3273 during host lookups.
3274
fe5b5d0b
PH
327574. The defer_ok option of callout verification was not working if it was used
3276 when verifying addresses in header lines, that is, for this case:
3277
3278 verify = header_sender/callout=defer_ok
3279
76a2d7ba
PH
328075. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3281 those file descriptors could be used for SMTP connections. If anything
3282 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3283 could be sent to the SMTP client, causing chaos. The daemon now opens
3284 stdin, stdout, and stderr to /dev/null when it puts itself into the
3285 background.
3286
328776. Arrange for output from Perl's "warn" command to be written to Exim's main
3288 log by default. The user can override this with suitable Perl magic.
3289
04f7d5b9
PH
329077. The use of log_message on a "discard" ACL verb, which is supposed to add to
3291 the log message when discard triggers, was not working for the DATA ACL or
3292 for the non-SMTP ACL.
3293
bc60667e
PH
329478. Error message wording change in sieve.c.
3295
bb6e88ff
PH
329679. If smtp_accept_max_per_host was set, the number of connections could be
3297 restricted to fewer than expected, because the daemon was trying to set up
3298 a new connection before checking whether the processes handling previous
3299 connections had finished. The check for completed processes is now done
3300 earlier. On busy systems, this bug wouldn't be noticed because something
3301 else would have woken the daemon, and it would have reaped the completed
3302 process earlier.
3303
1e70f85b
PH
330480. If a message was submitted locally by a user whose login name contained one
3305 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3306 It caused a spool format error. I have fixed the spool reading code. A
3307 related problem was that the "from" clause in the Received: line became
3308 illegal because of the space(s). It is now covered by ${quote_local_part.
3309
331081. Included the latest eximstats from Steve (adds average sizes to HTML Top
3311 tables).
3312
4e01f9d6
PH
331382. Updated OS/Makefile-AIX as per message from Mike Meredith.

331583. Patch from Sieve maintainer to fix unterminated string problem in
3316 "vacation" handling.
3317

PH
331884. Some minor changes to the Linux configuration files to help with other
3319 OS variants using glibc.
3320

PH
332185. One more patch for Sieve to update vacation handling to latest spec.

3324----------------------------------------------------
3325See the note above about the 4.44 and 4.50 releases.
3326----------------------------------------------------
3327
3328
3329Exim version 4.44
3330-----------------
3331
3332 1. Change 4.43/35 introduced a bug that caused file counts to be
3333 incorrectly computed when quota_filecount was set in an appendfile
3334 transport
3335
3336 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3337 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3338 place.
3339
3340 3. Give more explanation in the error message when the command for a transport
3341 filter fails to execute.
3342
3343 4. There are several places where Exim runs a non-Exim command in a
3344 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3345 was being done only for the command run by the queryprogram router. It is
3346 now done for all such subprocesses. The other cases are: ${run, transport
3347 filters, and the commands run by the lmtp and pipe transports.
3348
3349 5. Some older OS have a limit of 256 on the maximum number of file
3350 descriptors. Exim was using setrlimit() to set 1000 as a large value
3351 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3352 systems. I've change it so that if it can't get 1000, it tries for 256.
3353
3354 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3355 was an oversight, and furthermore, ever since the addition of extra
3356 controls (e.g. 4.43/32), the checks on when to allow different forms of
3357 "control" were broken. There should now be diagnostics for all cases when a
3358 control that does not make sense is encountered.
3359
3360 7. $recipients is now available in the predata ACL (oversight).
3361
3362 8. Tidy the search cache before the fork to do a delivery from a message
3363 received from the command line. Otherwise the child will trigger a lookup
3364 failure and thereby defer the delivery if it tries to use (for example) a
3365 cached ldap connection that the parent has called unbind on.
3366
3367 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3368 of $address_data from the recipient verification was clobbered by the
3369 sender verification.
3370
337110. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3372 was its contents. (It was OK if the option was not defined at all.)
3373
337411. A "Completed" log line is now written for messages that are removed from
3375 the spool by the -Mrm option.
3376
337712. $host_address is now set to the target address during the checking of
3378 ignore_target_hosts.
3379
338013. When checking ignore_target_hosts for an ipliteral router, no host name was
3381 being passed; this would have caused $sender_host_name to have been used if
3382 matching the list had actually called for a host name (not very likely,
3383 since this list is usually IP addresses). A host name is now passed as
3384 "[x.x.x.x]".
3385
338614. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3387 code that specifies a non-restarting handler (typically sigaction() in
3388 modern systems) in an attempt to fix a rare and obscure crash bug.
3389
339015. Narrowed the window for a race in the daemon that could cause it to ignore
3391 SIGCHLD signals. This is not a major problem, because they are used only to
3392 wake it up if nothing else does.
3393
339416. A malformed maildirsize file could cause Exim to calculate negative values
3395 for the mailbox size or file count. Odd effects could occur as a result.
3396 The maildirsize information is now recalculated if the size or filecount
3397 end up negative.
3398
339917. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3400 support for a long time. Removed HAVE_SYS_VFS_H.
3401
ea3a6f44 340218. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3403
340419. Allow an empty sender to be matched against a lookup in an address list.
3405 Previously the only cases considered were a regular expression, or an
3406 empty pattern.
3407
340820. Exim went into a mad DNS lookup loop when doing a callout where the
3409 host was specified on the transport, if the DNS lookup yielded more than
3410 one IP address.
3411
ea3a6f44
NM
341221. The RFC2047 encoding function was originally intended for short strings
3413 such as real names; it was not keeping to the 75-character limit for
