TF
87TF/03 Make the exiwhat support code safe for signals. Previously Exim might
88 lock up or crash if it happened to be inside a call to libc when it
89 got a SIGUSR1 from exiwhat.
90
91 The SIGUSR1 handler appends the current process status to the process
92 log which is later printed by exiwhat. It used to use the general
93 purpose logging code to do this, but several functions it calls are
94 not safe for signals.
95
96 The new output code in the SIGUSR1 handler is specific to the process
97 log, and simple enough that it's easy to inspect for signal safety.
98 Removing some special cases also simplifies the general logging code.
99 Removing the spurious timestamps from the process log simplifies
100 exiwhat.

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

724
6a3bceb1
PH
725PH/02 When an IPv6 address is converted to a string for single-key lookup
726 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
727 dots are used instead of colons so that keys in lsearch files need not
728 contain colons. This was done some time before quoting was made available
729 in lsearch files. However, iplsearch files do require colons in IPv6 keys
730 (notated using the quote facility) so as to distinguish them from IPv4
731 keys. This meant that lookups for IP addresses in host lists did not work
732 for iplsearch lookups.
733
734 This has been fixed by arranging for IPv6 addresses to be expressed with
735 colons if the lookup type is iplsearch. This is not incompatible, because
736 previously such lookups could never work.
737
738 The situation is now rather anomolous, since one *can* have colons in
739 ordinary lsearch keys. However, making the change in all cases is
740 incompatible and would probably break a number of configurations.

745MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
746 conversion specification without a maximum field width, thereby enabling
747 a rogue spamd server to cause a buffer overflow. While nobody in their
748 right mind would setup Exim to query an untrusted spamd server, an
749 attacker that gains access to a server running spamd could potentially
750 exploit this vulnerability to run arbitrary code as the Exim user.

MH
755MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
756 a directory entry by the name of the lookup key. Previously, if a
757 symlink pointed to a non-existing file or a file in a directory that
758 Exim lacked permissions to read, a lookup for a key matching that
759 symlink would fail. Now it is enough that a matching directory entry
760 exists, symlink or not. (Bugzilla 503.)

943PH/29 SMTP synchronization checks are implemented when a command is read -
944 there is a check that no more input is waiting when there shouldn't be

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

PH
1023 the response to the final '.' that terminates a message, but only in the
1024 case where the client has not sent further data following the '.'
1025 (unfortunately, this is allowed). However, in many cases there won't be
1026 any further data because there won't be any more messages to send. A call
1027 to select() can be used: if it shows that the input is "ready", there is
1028 either input waiting, or the socket has been closed. An attempt to read
1029 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1030 would have sent an OK response which the client would never have see.

1041PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1042 fixed by 4.65/MH/01 (is this a record?) are fixed:
1043
1044 (i) An empty string was always treated as zero by the numeric comparison
1045 operators. This behaviour has been restored.
1046
1047 (ii) It is documented that the numeric comparison operators always treat
1048 their arguments as decimal numbers. This was broken in that numbers
1049 starting with 0 were being interpreted as octal.
1050
1051 While fixing these problems I realized that there was another issue that
1052 hadn't been noticed. Values of message_size_limit (both the global option
1053 and the transport option) were treated as octal if they started with 0.
1054 The documentation was vague. These values are now always treated as
1055 decimal, and I will make that clear in the documentation.

1071 is held in a short int, deliveries were likely to be lost. As such a
1072 large number of recipients for a single message is ridiculous
1073 (performance will be very, very poor), I have chosen to impose a limit
1074 rather than extend the field.

2b1c6e3a
PH
1099PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1100 callout verification, Exim cached a "reject" for the entire domain. This
1101 is correct for most verifications, but it is not correct for a recipient
1102 verification with use_sender or use_postmaster set, because in that case
1103 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1104 case of MAIL FROM:<> rejection from other early rejections (e.g.
1105 rejection of HELO). When verifying a recipient using a non-null MAIL
1106 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1107 Whatever the result of the callout, the value of the domain cache is
1108 left unchanged (for any other kind of callout, getting as far as trying
1109 RCPT means that the domain itself is ok).

1143PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1145 probably the interface on which it is arriving) and not to the outgoing
1146 callout (which could be using a different interface). This has been
1147 changed to use the value of the helo_data option from the smtp transport
1148 instead - this is what is used when a message is actually being sent. If
1149 there is no remote transport (possible with a router that sets up host
1150 addresses), $smtp_active_hostname is used.

7befa435 1153 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1154 (a) The code assumed that strncpy() returns a negative number on buffer
1155 overflow, which isn't the case. Replaced with Exim's string_format()
1156 function.
1157 (b) There were several signed/unsigned issues. I just did the minimum
1158 hacking in of casts. There is scope for a larger refactoring.
1159 (c) The code used strcasecmp() which is not a standard C function.
1160 Replaced with Exim's strcmpic() function.
1161 (d) The code set only $1; it now sets $auth1 as well.
1162 (e) A simple test gave the error "authentication client didn't specify
1163 service in request". It would seem that Dovecot has changed its
1164 interface. Fortunately there's a specification; I followed it and
1165 changed what the client sends and it appears to be working now.

1171 address A is aliased to B and C, where B exists and C does not. Without
1172 -v the output is "A verified" because verification stops after a
1173 successful redirection if more than one address is generated. However,
1174 with -v the child addresses are also verified. Exim was outputting "A
1175 failed to verify" and then showing the successful verification for C,
1176 with its parentage. It now outputs "B failed to verify", showing B's
1177 parentage before showing the successful verification of C.

PH
1183PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1184 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1185 they consult the DNS. I had assumed they would set it the way they
1186 wanted; and indeed my experiments on Linux seem to show that in some
1187 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1188 To be on the safe side, however, I have now made the interface to
1189 host_find_byname() similar to host_find_bydns(), with an argument
1190 containing the DNS resolver options. The host_find_byname() function now
1191 sets these options at its start, just as host_find_bydns() does. The smtp
1192 transport options dns_qualify_single and dns_search_parents are passed to
1193 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1194 of host_find_byname() use the default settings of RES_DEFNAMES
1195 (qualify_single) but not RES_DNSRCH (search_parents).

1200 overdue, caused by the large number of possibilities that now exist.
1201 Originally there were few.) While I was there, I also converted the
1202 str(n)cmp tests so they don't re-test the leading "-" and the first
1203 character, in the hope this might squeeze out yet more improvement.

1205PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1206 flag allowing group syntax was set by the header_syntax check but not
1207 turned off, possible causing trouble later; (2) The flag was not being
1208 set at all for the header_verify test, causing "group"-style headers to
1209 be rejected. I have now set it in this case, and also caused header_
1210 verify to ignore an empty address taken from a group. While doing this, I
1211 came across some other cases where the code for allowing group syntax
1212 while scanning a header line wasn't quite right (mostly, not resetting
1213 the flag correctly in the right place). These bugs could have caused
1214 trouble for malformed header lines. I hope it is now all correct.

1216PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1218 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1219 but it didn't always do it. This confused somebody who was copying the
1220 code for some other use. I have removed all the tests.

1222PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1223 feature that was used to support insecure browsers during the U.S. crypto
1224 embargo. It requires special client support, and Exim is probably the
1225 only MTA that supported it -- and would never use it because real RSA is
1226 always available. This code has been removed, because it had the bad
1227 effect of slowing Exim down by computing (never used) parameters for the
1228 RSA_EXPORT functionality.

1230PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1233 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1234 if the connection is using TLS or if the remote IP is the same as the
1235 local IP, and the "valid-client-cert option" if a client certificate has
1236 been verified.

1267
1268PH/30 Exim was sometimes attempting to deliver messages that had suffered
1269 address errors (4xx response to RCPT) over the same connection as other
1270 messages routed to the same hosts. Such deliveries are always "forced",
1271 so retry times are not inspected. This resulted in far too many retries
1272 for the affected addresses. The effect occurred only when there were more
1273 hosts than the hosts_max_try setting in the smtp transport when it had
1274 the 4xx errors. Those hosts that it had tried were not added to the list
1275 of hosts for which the message was waiting, so if all were tried, there
1276 was no problem. Two fixes have been applied:
1277
1278 (i) If there are any address or message errors in an SMTP delivery, none
1279 of the hosts (tried or untried) are now added to the list of hosts
1280 for which the message is waiting, so the message should not be a
1281 candidate for sending over the same connection that was used for a
1282 successful delivery of some other message. This seems entirely
1283 reasonable: after all the message is NOT "waiting for some host".
1284 This is so "obvious" that I'm not sure why it wasn't done
1285 previously. Hope I haven't missed anything, but it can't do any
1286 harm, as the worst effect is to miss an optimization.
1287
1288 (ii) If, despite (i), such a delivery is accidentally attempted, the
1289 routing retry time is respected, so at least it doesn't keep
1290 hammering the server.

1305PH/35 The error "getsockname() failed: connection reset by peer" was being
1306 written to the panic log as well as the main log, but it isn't really
1307 panic-worthy as it just means the connection died rather early on. I have
1308 removed the panic log writing for the ECONNRESET error when getsockname()
1309 fails.
1310
48c7f9e2
PH
1311PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1312 runs only) independently of the message's sender address. This meant
1313 that, if the 4xx error was in fact related to the sender, a different
1314 message to the same recipient with a different sender could confuse
1315 things. In particualar, this can happen when sending to a greylisting
1316 server, but other circumstances could also provoke similar problems.
1317 I have changed the default so that the retry time for these errors is now
1318 based a combination of the sender and recipient addresses. This change
1319 can be overridden by setting address_retry_include_sender=false in the
1320 smtp transport.

1589 "Deny" causes Exim to reject the incoming connection with a 554 error.
1590 Unfortunately, if there is a major crisis, such as a disk failure,
1591 tcp-wrappers gives "deny", whereas what one would like would be some
1592 kind of temporary error. A kludge has been added to help with this.
1593 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1594 554 error is used if errno is still zero or contains ENOENT (which occurs
1595 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1596 451 error is used.

1618PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1619 folder from quota calculations, a direct delivery into this folder messed

1621 used only to exclude .Trash (or whatever) when the size of the mailbox
1622 was calculated. There was no check that a delivery was happening into an

1632PH/01 The code for finding all the local interface addresses on a FreeBSD
1633 system running IPv6 was broken. This may well have applied to all BSD
1634 systems, as well as to others that have similar system calls. The broken
1635 code found IPv4 interfaces correctly, but gave incorrect values for the
1636 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1637 that it would not match correctly against @[] and not recognize the IPv6
1638 addresses as local.

1681 autoreply, Exim could try to deliver to a non-existent relative file

1717 Instead, it always explicitly searches for A/AAAA records. This avoids
1718 major problems that occur when a DNS server includes only records of one
1719 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1720 fixed another bug: if SRV records were looked up and the corresponding
1721 address records were *not* found in the additional section, the port
1722 values from the SRV records were lost.

PH
1732PH/19 When calculating a retry time, Exim used to measure the "time since
1733 failure" by looking at the "first failed" field in the retry record. Now
1734 it does not use this if it is later than than the arrival time of the
1735 message. Instead it uses the arrival time. This makes for better
1736 behaviour in cases where some deliveries succeed, thus re-setting the
1737 "first failed" field. An example is a quota failure for a huge message
1738 when small messages continue to be delivered. Without this change, the
1739 "time since failure" will always be short, possible causing more frequent
1740 delivery attempts for the huge message than are intended.

1837PH/42 The content-scanning code uses fopen() to create files in which to put
1838 message data. Previously it was not paying any attention to the mode of
1839 the files. Exim runs with umask(0) because the rest of the code creates
1840 files with open(), and sets the required mode explicitly. Thus, these
1841 files were ending up world-writeable. This was not a big issue, because,
1842 being within the spool directory, they were not world-accessible. I have
1843 created a function called modefopen, which takes an additional mode
1844 argument. It sets umask(777), creates the file, chmods it to the required
1845 mode, then resets the umask. All the relevant calls to fopen() in the

1886 was used in LMTP mode. This meant that they could be retried too
1887 frequently, and not timed out correctly.
1888
1889 (ii) Exim was setting the flag that allows error details to be returned
1890 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1891 recipients that were returned after the DATA command.
1892
1893PH/53 This is related to PH/52, but is more general: for any failing address,
1894 when detailed error information was permitted to be returned to the

1973 descriptor number as the socket. This naturally causes chaos. The fix is
1974 not to close the socket in ip_connect(); the socket should be closed by
1975 the function that creates it. There was only one place in the code where
1976 this was missing, in the iplookup router, which I don't think anybody now
1977 uses, but I've fixed it anyway.

1996PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
1997
1998 (1) Generate an error if the third argument for the ${prvs expansion is
1999 not a single digit.
2000
2001 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2002 string.
2003
2004 (3) Reset the variables that are obtained from the first argument of
2005 ${prvscheck and used in the second argument before leaving the code,
2006 because their memory is reclaimed, so using them afterwards may do
2007 silly things.
2008
2009 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2010 one (it's much easier than Tom thought :-).
2011
2012 (5) Because of (4), we can now allow for the use of $prvscheck_result
2013 inside the third argument.

2024
2025 => >A.N.Other <ano@some.domain> <original@ddress> ...
2026
2027 This has been changed so that it extracts the operative address. There
2028 may be more than one such address. If so, they are comma-separated, like

PH
2033PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2034 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2035 not being looked up in the rDNS to get a host name, Exim was showing the
2036 IP address twice in Received: lines, even though the IP addresses were
2037 identical. For example:
2038
2039 Received: from [1.2.3.4] (helo=[1.2.3.4])
2040
2041 However, if the real host name was known, it was omitting the HELO data
2042 if it matched the actual IP address. This has been tidied up so that it
2043 doesn't show the same IP address twice.

2069PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2071
2072 Auto-submitted: auto-generated
2073
2074 in the messages that it generates (bounce messages and others, such as
2075 warnings). In the case of bounce messages for non-SMTP mesages, there was
2076 also a typo: it was using "Auto_submitted" (underscore instead of
2077 hyphen). Since every message generated by Exim is necessarily in response
2078 to another message, thes have all been changed to:
2079
2080 Auto-Submitted: auto-replied
2081
2082 in accordance with these statements in the RFC:
2083
2084 The auto-replied keyword:
2085
2086 - SHOULD be used on messages sent in direct response to another
2087 message by an automatic process,
2088
2089 - MUST NOT be used on manually-generated messages,
2090
2091 - MAY be used on Delivery Status Notifications (DSNs) and Message
2092 Disposition Notifications (MDNs),

2132PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2133 canonical form (as documented). However, after a host name lookup from
2134 the IP address, check_host() was doing a simple string comparison with
2135 addresses acquired from the DNS when checking that the found name did
2136 have the original IP as one of its addresses. Since any found IPv6
2137 addresses are likely to be in abbreviated form, the comparison could
2138 fail. Luckily, there already exists a function for doing the comparison
2139 by converting both addresses to binary, so now that is used instead of
2140 the text comparison.

2142PH/20 There was another similar case to PH/19, when a complete host name was

2437PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2438 with the definition in sysexits.h (which is #included earlier).
2439 Fortunately, Exim does not actually use EX_OK. The code used to try to
2440 preserve the sysexits.h value, by assumimg that macro definitions were
2441 scanned for macro replacements. I have been disabused of this notion,
2442 so now the code just undefines EX_OK before #including unistd.h.

2444PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2445 in the smtp transport. When a block could not be written in a single
2446 write() function, the timeout was being re-applied to each part-write.
2447 This seems wrong - if the receiver was accepting one byte at a time it
2448 would take for ever. The timeout is now adjusted when this happens. It
2449 doesn't have to be particularly precise.

2525 case the guess is not the same as the compiled default, so the script
2526 suddenly stopped working when I started to use syslog. The patch checks
2527 to see if log_file_path is "". If so, it attempts to read it from exim

2529 falls back to the previous guessing code."

2585PH/27 If a dnslookup or manualroute router is set with verify=only, it need not

2588 read the rcpt_include_affixes from the non-existent transport. Now it

2657
2658PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2659 that changes the way the GnuTLS parameters are stored in the cache file.
2660 The new format can be generated externally. For backward compatibility,
2661 if the data in the cache doesn't make sense, Exim assumes it has read an
2662 old-format file, and it generates new data and writes a new file. This
2663 means that you can't go back to an older release without removing the
2664 file.
2665
2666PH/03 A redirect router that has both "unseen" and "one_time" set does not
2667 work if there are any delivery delays because "one_time" forces the
2668 parent to be marked "delivered", so its unseen clone is never tried
2669 again. For this reason, Exim now forbids the simultaneous setting of
2670 these two options.
2671
2672PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2673 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2674 entry if you want to know the details. The fix, however, neglected to
2675 consider the case when local delivery batching is involved. The test for
2676 "previously delivered" was not happening when checking to see if an
2677 address could be batched with a previous (undelivered) one; under
2678 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2679 address.

PH
2680
2681PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2684PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2685 header_syntax) but Exim was just ignoring anything given after a slash.
2686 In particular, this caused confusion with an attempt to use "verify =
2687 reverse_host_lookup/defer_ok". An error is now given when options are
2688 supplied for verify items that do not have them. (Maybe reverse_host_
2689 lookup should have a defer_ok option, but that's a different point.)
2690
2691PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2744 the file with the wrong ownership). There was no test for failure of this
2745 fork() call, which would lead to the process getting stuck as it waited
2746 for a non-existent subprocess. Forks do occasionally fail when resources

2753 the result was a log entry for a synchronization error with an empty
2754 string after "input=" when read() returned zero. If read() returned -1

2776 => SASL tests which mechs of all available mechs actually work
2777 => three warnings about OTP not working
2778 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2779
2780 With the patch, sasl_listmech() also gets called three times. But now
2781 SASL's mech_list option is set to the server_mech specified in the the
2782 authenticator. Or in other words, the answer from sasl_listmech()
2783 gets limited to just the mech you're testing for (which is different
2784 for each call.)
2785 => the return list contains just 'plain' or 'login', 'cram-md5' or
2786 nothing depending on the value of ob->server_mech.
2787
2788 I've just tested the patch: Authentication still works fine,
2789 unavailable mechs specified in the exim configuration are still
2790 caught, and the auth.log warnings about OTP are gone."

PH
2854PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2855 the grounds that routing the same address twice would always produce the
2856 same answer. This might have been true once, but it is certainly no
2857 longer true now. Routing a child address may depend on the previous
2858 routing that produced that child. Some complicated redirection strategies
2859 went wrong when messages had multiple recipients, and made Exim's
2860 behaviour dependent on the order in which the addresses were given.
2861
2862 I have moved the duplicate checking until after the routing is complete.
2863 Exim scans the addresses that are assigned to local and remote
2864 transports, and removes any duplicates. This means that more work will be
2865 done, as duplicates will always all be routed, but duplicates are
2866 presumably rare, so I don't expect this is of any significance.
2867
2868 For deliveries to pipes, files, and autoreplies, the duplicate checking
2869 still happens during the routing process, since they are not going to be
2870 routed further.

2915 consistency with the overall process timeout, these timeouts are now
2916 treated as errors, giving rise to delivery failures by default. However,
2917 there is now a new Boolean option for the pipe transport called

2929A note about Exim versions 4.44 and 4.50
2930----------------------------------------
2931
2932Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2933changes of various kinds. As a consequence, a big documentation update was
2934needed. This delayed the release for rather longer than seemed good, especially
2935in the light of a couple of (minor) security issues. Therefore, the changes
2936that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2937release. So 4.44 and 4.50 are in effect two different branches that both start
2938from 4.43.
2939
2940I have left the 4.50 change log unchanged; it contains all the changes since
29414.43. The change log for 4.44 is below; many of its items are identical to
2942those for 4.50. This seems to be the most sensible way to preserve the
2943historical information.

2961 5. There are several places where Exim runs a non-Exim command in a
2962 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2963 was being done only for the command run by the queryprogram router. It is
2964 now done for all such subprocesses. The other cases are: ${run, transport
2965 filters, and the commands run by the lmtp and pipe transports.

2967 6. Added CONFIGURE_GROUP build-time option.

2969 7. Some older OS have a limit of 256 on the maximum number of file
2970 descriptors. Exim was using setrlimit() to set 1000 as a large value
2971 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2972 systems. I've change it so that if it can't get 1000, it tries for 256.

301922. $host_address is now set to the target address during the checking of
3020 ignore_target_hosts.
3021
302223. When checking ignore_target_hosts for an ipliteral router, no host name was
3023 being passed; this would have caused $sender_host_name to have been used if
3024 matching the list had actually called for a host name (not very likely,
3025 since this list is usually IP addresses). A host name is now passed as
3026 "[x.x.x.x]".
3027
7d468ab8
PH
302824. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3029 code that specifies a non-restarting handler (typically sigaction() in
3030 modern systems) in an attempt to fix a rare and obscure crash bug.
3031
303225. Narrowed the window for a race in the daemon that could cause it to ignore
3033 SIGCHLD signals. This is not a major problem, because they are used only to
3034 wake it up if nothing else does.

PH
303626. A malformed maildirsize file could cause Exim to calculate negative values

3038 The maildirsize information is now recalculated if the size or filecount
3039 end up negative.

PH
304629. In an address list, if the pattern was not a regular expression, an empty
3047 subject address (from a bounce message) matched only if the pattern was an
3048 empty string. Non-empty patterns were not even tested. This was the wrong
3049 because it is perfectly reasonable to use an empty address as part of a
3050 database query. An empty address is now tested by patterns that are
3051 lookups. However, all the other forms of pattern expect the subject to
3052 contain a local part and a domain, and therefore, for them, an empty
3053 address still always fails if the pattern is not itself empty.
3054
d8ef3577
PH
305530. Exim went into a mad DNS loop when attempting to do a callout where the
3056 host was specified on an smtp transport, and looking it up yielded more
3057 than one IP address.
3058
5cb8cbc6
PH
305931. Re-factored the code for checking spool and log partition space into a
3060 function that finds that data and another that does the check. The former
3061 is then used to implement four new variables: $spool_space, $log_space,
3062 $spool_inodes, and $log_inodes.
3063
14702f5b
PH
306432. The RFC2047 encoding function was originally intended for short strings
3065 such as real names; it was not keeping to the 75-character limit for
3066 encoded words that the RFC imposes. It now respects the limit, and
3067 generates multiple encoded words if necessary. To be on the safe side, I
3068 have increased the buffer size for the ${rfc2047: expansion operator from
3069 1024 to 2048 bytes.
3070
063b1e99
PH
307133. It is now permitted to omit both strings after an "if" condition; if the
3072 condition is true, the result is "true". As before, when the second string
3073 is omitted, a false condition yields an empty string. This makes it less
3074 cumbersome to write custom ACL and router conditions.
3075
652e1b65
PH
307634. Failure to deliver a bounce message always caused it to be frozen, even if
3077 there was an errors_to setting on the router. The errors_to setting is now
3078 respected.
3079
6f0c9a4f
PH
308035. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3081 canonical form (fully expanded) before being placed in
3082 $sender_host_address.

33397d19
PH
308436. The table in the code that translates DNS record types into text (T_A to
3085 "A" for instance) was missing entries for NS and CNAME. It is just possible
3086 that this could have caused confusion if both these types were looked up
3087 for the same domain, because the text type is used as part of Exim's
3088 per-process caching. But the chance of anyone hitting this buglet seems
3089 very small.

PH
309137. The dnsdb lookup has been extended in a number of ways.

3156 increasing the size of one of Exim's internal buffers (big_buffer) that
3157 happened as part of the Exiscan merge. However, to be on the safe side, I
3158 have made the code more robust (and fixed the comments that describe what

3172 Organization Units. When I tried to give exim partial DN, the exit code
3173 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3174 But simultaneously result of request was absolutely normal ldap result,
3175 so I produce this patch..."
3176
3295e65b
PH
3177 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3178 REFERENCE, so I have modified the code to exclude the patch when that macro
3179 is not defined.

PH
318155. Some experimental protocols are using DNS PTR records for new purposes. The
3182 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3183 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3184 leaves it alone. Component reversal etc. now happens only for IP addresses.

318756. Improve error message when ldap_search() fails in OpenLDAP or Solaris LDAP.

PH
318957. Double the size of the debug message buffer (to 2048) so that more of very
3190 long debug lines gets shown.
3191
18ce445d
PH
319258. The exicyclog utility now does better if the number of log files to keep
3193 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3194

PH
319559. Two changes related to the smtp_active_hostname option:
3196
3197 (1) $smtp_active_hostname is now available as a variable.
3198 (2) The default for smtp_banner uses $smtp_active_hostname instead
3199 of $primary_hostname.

b975ba52
PH
320160. The host_aton() function is supposed to be passed a string that is known
3202 to be a valid IP address. However, in the case of IPv6 addresses, it was
3203 not checking this. This is a hostage to fortune. Exim now panics and dies
3204 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3205 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3206 components; fortuitously, this particular loophole had already been fixed
3207 by change 4.50/55 above.
3208
3209 If there are any other similar loopholes, the new check in host_aton()
3210 itself should stop them being exploited. The report I received stated that
3211 data on the command line could provoke the exploit when Exim was running as
3212 exim, but did not say which command line option was involved. All I could
3213 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3214 running as the user.

321761. There was a buffer overflow vulnerability in the SPA authentication code
3218 (which came originally from the Samba project). I have added a test to the
3219 spa_base64_to_bits() function which I hope fixes it.

322262. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3223 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3224
d95f9fdb
PH
322563. The daemon start-up calls getloadavg() while still root for those OS that
3226 need the first call to be done as root, but it missed one case: when
3227 deliver_queue_load_max is set with deliver_drop_privilege. This is
3228 necessary for the benefit of the queue runner, because there is no re-exec
3229 when deliver_drop_privilege is set.
3230
86b8287f
PH
323164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3232 This has been fixed.
3233
60dc5e56
PH
323465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3235 was in use, was not putting the data itself into the right store pool;
3236 consequently, it could be overwritten for a subsequent message in the same
3237 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3238 the caching.)
3239

PH
324066. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3241
a5a28604
PH
324267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3243 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3244 the function were treating the return as a boolean value, which happened to
3245 work because 0=false and not-0=true, but is not correct code.
3246
7e634d24
PH
324768. The host_aton() function was not handling scoped IPv6 addresses (those
3248 with, for example, "%eth0" on the end) correctly.
3249
3e11c26b
PH
325069. Fixed some compiler warnings in acl.c for the bitmaps specified with
3251 negated items (that is, ~something) in unsigned ints. Some compilers
3252 apparently mutter when there is no cast.
3253
6729cf78
PH
325470. If an address verification called from an ACL failed, and did not produce a
3255 user-specific message (i.e. there was only a "system" message), nothing was
3256 put in $acl_verify_message. In this situation, it now puts the system
3257 message there.
3258
00f00ca5
PH
325971. Change 4.23/11 added synchronization checking at the start of an SMTP
3260 session; change 4.31/43 added the unwanted input to the log line - except
3261 that it did not do this in the start of session case. It now does.
3262
c9bdd01c
PH
326372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3264 This is wrong and can cause the other end to generate a synchronization
3265 error if it is another Exim or anything else that does the synchronization
3266 check. A QUIT command is no longer sent after a timeout.
3267

PH
326873. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3269 during host lookups.
3270

PH
327174. The defer_ok option of callout verification was not working if it was used
3272 when verifying addresses in header lines, that is, for this case:
3273
3274 verify = header_sender/callout=defer_ok
3275
76a2d7ba
PH
327675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3277 those file descriptors could be used for SMTP connections. If anything
3278 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3279 could be sent to the SMTP client, causing chaos. The daemon now opens
3280 stdin, stdout, and stderr to /dev/null when it puts itself into the
3281 background.
3282
328376. Arrange for output from Perl's "warn" command to be written to Exim's main
3284 log by default. The user can override this with suitable Perl magic.
3285
04f7d5b9
PH
328677. The use of log_message on a "discard" ACL verb, which is supposed to add to
3287 the log message when discard triggers, was not working for the DATA ACL or
3288 for the non-SMTP ACL.
3289
bc60667e
PH
329078. Error message wording change in sieve.c.
3291
bb6e88ff
PH
329279. If smtp_accept_max_per_host was set, the number of connections could be
3293 restricted to fewer than expected, because the daemon was trying to set up
3294 a new connection before checking whether the processes handling previous
3295 connections had finished. The check for completed processes is now done
3296 earlier. On busy systems, this bug wouldn't be noticed because something
3297 else would have woken the daemon, and it would have reaped the completed
3298 process earlier.
3299
1e70f85b
PH
330080. If a message was submitted locally by a user whose login name contained one
3301 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3302 It caused a spool format error. I have fixed the spool reading code. A
3303 related problem was that the "from" clause in the Received: line became
3304 illegal because of the space(s). It is now covered by ${quote_local_part.
3305
330681. Included the latest eximstats from Steve (adds average sizes to HTML Top
3307 tables).

3320----------------------------------------------------
3321See the note above about the 4.44 and 4.50 releases.
3322----------------------------------------------------
3323
3324
3325Exim version 4.44
3326-----------------
3327
3328 1. Change 4.43/35 introduced a bug that caused file counts to be
3329 incorrectly computed when quota_filecount was set in an appendfile
3330 transport
3331
3332 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3333 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3334 place.
3335
3336 3. Give more explanation in the error message when the command for a transport
3337 filter fails to execute.
3338
3339 4. There are several places where Exim runs a non-Exim command in a
3340 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3341 was being done only for the command run by the queryprogram router. It is
3342 now done for all such subprocesses. The other cases are: ${run, transport
3343 filters, and the commands run by the lmtp and pipe transports.
3344
3345 5. Some older OS have a limit of 256 on the maximum number of file
3346 descriptors. Exim was using setrlimit() to set 1000 as a large value
3347 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3348 systems. I've change it so that if it can't get 1000, it tries for 256.
3349
3350 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3351 was an oversight, and furthermore, ever since the addition of extra
3352 controls (e.g. 4.43/32), the checks on when to allow different forms of
3353 "control" were broken. There should now be diagnostics for all cases when a
3354 control that does not make sense is encountered.
3355
3356 7. $recipients is now available in the predata ACL (oversight).
3357
3358 8. Tidy the search cache before the fork to do a delivery from a message
3359 received from the command line. Otherwise the child will trigger a lookup
3360 failure and thereby defer the delivery if it tries to use (for example) a
3361 cached ldap connection that the parent has called unbind on.
3362
3363 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3364 of $address_data from the recipient verification was clobbered by the
3365 sender verification.
3366
336710. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3368 was its contents. (It was OK if the option was not defined at all.)
3369
337011. A "Completed" log line is now written for messages that are removed from
3371 the spool by the -Mrm option.
3372
337312. $host_address is now set to the target address during the checking of
3374 ignore_target_hosts.
3375
337613. When checking ignore_target_hosts for an ipliteral router, no host name was
3377 being passed; this would have caused $sender_host_name to have been used if
3378 matching the list had actually called for a host name (not very likely,
3379 since this list is usually IP addresses). A host name is now passed as
3380 "[x.x.x.x]".
3381
338214. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3383 code that specifies a non-restarting handler (typically sigaction() in
3384 modern systems) in an attempt to fix a rare and obscure crash bug.
3385
338615. Narrowed the window for a race in the daemon that could cause it to ignore
3387 SIGCHLD signals. This is not a major problem, because they are used only to
3388 wake it up if nothing else does.
3389
339016. A malformed maildirsize file could cause Exim to calculate negative values
3391 for the mailbox size or file count. Odd effects could occur as a result.
3392 The maildirsize information is now recalculated if the size or filecount
3393 end up negative.
3394
339517. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3396 support for a long time. Removed HAVE_SYS_VFS_H.
3397
ea3a6f44 339818. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3399
340019. Allow an empty sender to be matched against a lookup in an address list.
3401 Previously the only cases considered were a regular expression, or an
3402 empty pattern.
3403
340420. Exim went into a mad DNS lookup loop when doing a callout where the
3405 host was specified on the transport, if the DNS lookup yielded more than
3406 one IP address.
3407
ea3a6f44
NM
340821. The RFC2047 encoding function was originally intended for short strings
3409 such as real names; it was not keeping to the 75-character limit for
3410 encoded words that the RFC imposes. It now respects the limit, and
3411 generates multiple encoded words if necessary. To be on the safe side, I
3412 have increased the buffer size for the ${rfc2047: expansion operator from
3413 1024 to 2048 bytes.
