56PP/14 TLS fixes for OpenSSL: support TLS 1.1 & 1.2; new "openssl_options"
57 values; set SSL_MODE_AUTO_RETRY so that OpenSSL will retry a read
58 or write after TLS renegotiation, which otherwise led to messages
59 "Got SSL error 2".

86PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
87 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.

JH
105 This may cause build issues on older platforms.
106
17c76198
PP
107PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
108 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
109 gnutls_require_mac & gnutls_require_protocols (no longer supported).
110 Added SNI support via GnuTLS too.

124
08488c86
PP
125PP/29 Fix three issues highlighted by clang analyser static analysis.
126 Only crash-plausible issue would require the Cambridge-specific
127 iplookup router and a misconfiguration.
128 Report from Marcin Mirosław.
129
6475bd82
PP
130PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
131
81f91683
PP
132PP/31 %D in printf continues to cause issues (-Wformat=security), so for
133 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
134 As part of this, removing so much warning spew let me fix some minor
135 real issues in debug logging.
136
5779e6aa
PP
137PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
138 assignment on my part. Fixed.
139
3375e053
PP
140PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
141 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
142 Janne Snabb (who went above and beyond: thank you).
143
144PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
145 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
146 relatively easy to get wrong. Should also expose TLS library linkage
147 problems.
3375e053 148
9d26b8c0
PP
149PP/35 Pull in <features.h> on Linux, for some portability edge-cases of

165 when unlink() failed. See also change 4.74-TF/03.
166
921b12ca
TF
167TF/03 Make the exiwhat support code safe for signals. Previously Exim might
168 lock up or crash if it happened to be inside a call to libc when it
169 got a SIGUSR1 from exiwhat.
170
171 The SIGUSR1 handler appends the current process status to the process
172 log which is later printed by exiwhat. It used to use the general
173 purpose logging code to do this, but several functions it calls are
174 not safe for signals.
175
176 The new output code in the SIGUSR1 handler is specific to the process
177 log, and simple enough that it's easy to inspect for signal safety.
178 Removing some special cases also simplifies the general logging code.
179 Removing the spurious timestamps from the process log simplifies
180 exiwhat.
181
c99ce5c9
TF
182TF/04 Improved ratelimit ACL condition.
183
184 The /noupdate option has been deprecated in favour of /readonly which
185 has clearer semantics. The /leaky, /strict, and /readonly update modes
186 are mutually exclusive. The update mode is no longer included in the
187 database key; it just determines when the database is updated. (This
188 means that when you upgrde Exim will forget old rate measurements.)
189
190 Exim now checks that the per_* options are used with an update mode that
191 makes sense for the current ACL. For example, when Exim is processing a
192 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
193 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
194 must specify per_mail/readonly. If you omit the update mode it defaults to
195 /leaky where that makes sense (as before) or /readonly where required.
196
197 The /noupdate option is now undocumented but still supported for
198 backwards compatibility. It is equivalent to /readonly except that in
199 ACLs where /readonly is required you may specify /leaky/noupdate or
200 /strict/noupdate which are treated the same as /readonly.
201
202 A useful new feature is the /count= option. This is a generalization
203 of the per_byte option, so that you can measure the throughput of other
204 aggregate values. For example, the per_byte option is now equivalent
205 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
206
207 The per_rcpt option has been generalized using the /count= mechanism
208 (though it's more complicated than the per_byte equivalence). When it is
209 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
210 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
211 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
212 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
213 Note that using per_rcpt with a non-readonly update mode in more than
214 one ACL will cause the recipients to be double-counted. (The per_mail
215 and per_byte options don't have this problem.)
216
217 The handling of very low rates has changed slightly. If the computed rate
218 is less than the event's count (usually one) then this event is the first
219 after a long gap. In this case the rate is set to the same as this event's
220 count, so that the first message of a spam run is counted properly.
221
222 The major new feature is a mechanism for counting the rate of unique
223 events. The new per_addr option counts the number of different
224 recipients that someone has sent messages to in the last time period. It
225 behaves like per_rcpt if all the recipient addresses are different, but
226 duplicate recipient addresses do not increase the measured rate. Like
227 the /count= option this is a general mechanism, so the per_addr option
228 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
229 example, measure the rate that a client uses different sender addresses
230 with the options per_mail/unique=$sender_address. There are further
231 details in the main documentation.

802
803PH/01 Another patch from the Sieve maintainer.
804
6a3bceb1
PH
805PH/02 When an IPv6 address is converted to a string for single-key lookup
806 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
807 dots are used instead of colons so that keys in lsearch files need not
808 contain colons. This was done some time before quoting was made available
809 in lsearch files. However, iplsearch files do require colons in IPv6 keys
810 (notated using the quote facility) so as to distinguish them from IPv4
811 keys. This meant that lookups for IP addresses in host lists did not work
812 for iplsearch lookups.
813
814 This has been fixed by arranging for IPv6 addresses to be expressed with
815 colons if the lookup type is iplsearch. This is not incompatible, because
816 previously such lookups could never work.
817
818 The situation is now rather anomolous, since one *can* have colons in
819 ordinary lsearch keys. However, making the change in all cases is
820 incompatible and would probably break a number of configurations.
821

TK
822TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
823 version.

MH
825MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
826 conversion specification without a maximum field width, thereby enabling
827 a rogue spamd server to cause a buffer overflow. While nobody in their
828 right mind would setup Exim to query an untrusted spamd server, an
829 attacker that gains access to a server running spamd could potentially
830 exploit this vulnerability to run arbitrary code as the Exim user.

832TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
833 $primary_hostname instead of what libspf2 thinks the hosts name is.
834
0f2cbd1b
MH
835MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
836 a directory entry by the name of the lookup key. Previously, if a
837 symlink pointed to a non-existing file or a file in a directory that
838 Exim lacked permissions to read, a lookup for a key matching that
839 symlink would fail. Now it is enough that a matching directory entry
840 exists, symlink or not. (Bugzilla 503.)
841
2b85bce7
PH
842PH/03 The body_linecount and body_zerocount variables are now exported in the
843 local_scan API.

846
6c512171
PH
847PH/05 Unset $tls_cipher and $tls_peerdn before making a connection as a client.
848 This means they are set thereafter only if the connection becomes
849 encrypted.
850

852 by clients under certain conditions.

879
8932dffe
PH
880PH/18 If a system quota error occurred while trying to create the file for
881 a maildir delivery, the message "Mailbox is full" was not appended to the
882 bounce if the delivery eventually timed out. Change 4.67/27 below applied
883 only to a quota excession during the actual writing of the file.
d6a60c0f 884
ddea74fa 885PH/19 It seems that peer DN values may contain newlines (and other non-printing
48ed62d9
PH
886 characters?) which causes problems in log lines. The DN values are now
887 passed through string_printing() before being added to log lines.
888

b7670459

MH
906MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
907 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
908 Jan Srzednicki.
909
b4ed4da0
PH
910PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
911 issue a MAIL command.
912
431b7361
PH
913PH/02 In an ACL statement such as
914
915 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
916
917 if a client was not listed at all, or was listed with a value other than
918 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
919 the condition was not true (as it should be), so access was not denied.
920 The bug was that the ! inversion was incorrectly passed on to the second
921 item. This has been fixed.
922
923PH/03 Added additional dnslists conditions == and =& which are different from
924 = and & when the dns lookup returns more than one IP address.
925
83da1223
PH
926PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
927 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
928
54fc8428
PH
929PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
930 FSYNC, which compiles an option called disable_fsync that allows for
931 bypassing fsync(). The documentation is heavily laced with warnings.
932
34c5e8dd
SC
933SC/01 Updated eximstats to collate all SpamAssassin rejects into one bucket.

PH
935PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
936 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
937 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
938 including adding "make clean"; (3) Added -fPIC when compiling the test
939 dynamically loaded module, to get rid of a warning.
940
0e8a9471
MH
941MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
942 message fails, move_frozen_messages = true and ignore_bounce_errors_after
943 = 0s. The bug is otherwise harmless.
944
f0872424
PH
945PH/07 There was a bug in the dovecot authenticator such that the value of
946 $auth1 could be overwritten, and so not correctly preserved, after a
947 successful authentication. This usually meant that the value preserved by
948 the server_setid option was incorrect.
949
b01dd148
PH
950PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.

6bf342e1
PH
952PH/09 Installed PCRE release 7.0.
953
273f34d0
PH
954PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
955 run for batched SMTP input. It is now run at the start of every message
956 in the batch. While fixing this I discovered that the process information
957 (output by running exiwhat) was not always getting set for -bs and -bS
958 input. This is fixed, and it now also says "batched" for BSMTP.
959
cf8b11a5
PH
960PH/11 Added control=no_pipelining.
961
41c7c167
PH
962PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
963 patch, slightly modified), and move the expansion of helo_data till after
964 the connection is made in the smtp transport (so it can use these
965 values).

977PH/18 Flush SMTP output before performing a callout, unless control =
978 no_callout_flush is set.
979
09945f1e
PH
980PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
981 was true (the default) a successful delivery failed to delete the retry
982 item, thus causing premature timeout of the address. The bug is now
983 fixed.
984
c51b8e75
PH
985PH/20 Added hosts_avoid_pipelining to the smtp transport.
986
e28326d8
PH
987PH/21 Long custom messages for fakedefer and fakereject are now split up
988 into multiline reponses in the same way that messages for "deny" and
989 other ACL rejections are.

992 with slight modification.

995 draft, changing the syntax and factoring some duplicate code".
996

PH
997PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
998 for deliveries of the second and subsequent messages over the same SMTP
999 connection.

PH
1001PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
1002 ${reduce, with only minor "tidies".

PH
1006PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
1007 expansion side effects.
1008
5a11a7b4
PH
1009PH/27 When a message times out after an over-quota error from an Exim-imposed
1010 quota, the bounce message says "mailbox is full". This message was not
1011 being given when it was a system quota that was exceeded. It now should
1012 be the same.
1013
0e20aff9
MH
1014MH/03 Made $recipients available in local_scan(). local_scan() already has
1015 better access to the recipient list through recipients_list[], but
1016 $recipients can be useful in postmaster-provided expansion strings.
1017
ca86f471
PH
1018PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1019 in the case of a MAIL command with additional options following the
1020 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1021 were accidentally chopped off.
1022
a14e5636
PH
1023PH/29 SMTP synchronization checks are implemented when a command is read -
1024 there is a check that no more input is waiting when there shouldn't be
1025 any. However, for some commands, a delay in an ACL can mean that it is
1026 some time before the response is written. In this time, more input might
1027 arrive, invalidly. So now there are extra checks after an ACL has run for
1028 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1029 pipelining has not been advertised.
1030
ec95d1a6
PH
1031PH/30 MH's patch to allow iscntrl() characters to be list separators.
1032
42855d71
PH
1033PH/31 Unlike :fail:, a custom message specified with :defer: was not being
1034 returned in the SMTP response when smtp_return_error_details was false.
1035 This has been fixed.
1036
57c2c631
PH
1037PH/32 Change the Dovecot authenticator to use read() and write() on the socket
1038 instead of the C I/O that was originally supplied, because problems were
1039 reported on Solaris.
1040
58c01c94
PH
1041PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1042 Exim which did not show up earlier: it was assuming that a call to
1043 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1044 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1045 was a macro that became an assignment, so it seemed to work. This has
1046 changed to a proper function call with a void return, hence the compile
1047 error. Exim's code has been fixed.
1048
dee5a20a
PH
1049PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
1050 cpus.

1055
79749a79
PH
1056PH/37 If a message is not accepted after it has had an id assigned (e.g.
1057 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
1058 "Completed" line in the log. When some messages of this type were
1059 selected by exigrep, they were listed as "not completed". Others were
1060 picked up by some special patterns. I have improved the selection
1061 criteria to be more general.
79749a79 1062
c456d9bb
PH
1063PH/38 The host_find_failed option in the manualroute router can now be set
1064 to "ignore", to completely ignore a host whose IP address cannot be
1065 found. If all hosts are ignored, the behaviour is controlled by the new
1066 host_all_ignored option.
1067
cd9868ec
PH
1068PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1069 homing or because of multiple MX records with /mx) generated more than
1070 one IP address, and the following item turned out to be the local host,
1071 all the secondary addresses of the first item were incorrectly removed
1072 from the list, along with the local host and any following hosts (which
1073 is what is supposed to happen).
1074
ebeaf996
PH
1075PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1076 whoever called Exim into the -H file. In the case of the daemon it was
1077 behaving confusingly. When first started, it used values for whoever
1078 started the daemon, but after a SIGHUP it used the Exim user (because it
1079 calls itself on a restart). I have changed the code so that it now always
1080 uses the Exim user.
1081
2679d413
PH
1082PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1083 message are rejected with the same error (e.g. no authentication or bad
1084 sender address), and a DATA command is nevertheless sent (as can happen
1085 with PIPELINING or a stupid MUA), the error message that was given to the
1086 RCPT commands is included in the rejection of the DATA command. This is
1087 intended to be helpful for MUAs that show only the final error to their
1088 users.

1100PH/43 Yet another patch from the Sieve maintainer.
1101
58eb016e 1102PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1103 the response to the final '.' that terminates a message, but only in the
1104 case where the client has not sent further data following the '.'
1105 (unfortunately, this is allowed). However, in many cases there won't be
1106 any further data because there won't be any more messages to send. A call
1107 to select() can be used: if it shows that the input is "ready", there is
1108 either input waiting, or the socket has been closed. An attempt to read
1109 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1110 would have sent an OK response which the client would never have see.
563b63fa
PH
1111 This could lead to message repetition. This fix should cure that, at
1112 least in a lot of common cases.

1118Exim version 4.66
1119-----------------
1120
1121PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1122 fixed by 4.65/MH/01 (is this a record?) are fixed:
1123
1124 (i) An empty string was always treated as zero by the numeric comparison
1125 operators. This behaviour has been restored.
1126
1127 (ii) It is documented that the numeric comparison operators always treat
1128 their arguments as decimal numbers. This was broken in that numbers
1129 starting with 0 were being interpreted as octal.
1130
1131 While fixing these problems I realized that there was another issue that
1132 hadn't been noticed. Values of message_size_limit (both the global option
1133 and the transport option) were treated as octal if they started with 0.
1134 The documentation was vague. These values are now always treated as
1135 decimal, and I will make that clear in the documentation.

4362ff0d
PH
1149PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1150 child addresses, Exim now panics and dies. Previously, because the count
1151 is held in a short int, deliveries were likely to be lost. As such a
1152 large number of recipients for a single message is ridiculous
1153 (performance will be very, very poor), I have chosen to impose a limit
1154 rather than extend the field.

TK
1160TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1161 leftover -K file (the existence of which was triggered by #402).
1162 While we were at it, introduced process PID as part of the -K
1163 filename. This should rule out race conditions when creating
1164 these files.
1165
1166TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1167 processing considerably. Previous code took too long for large mails,
1168 triggering a timeout which in turn triggers #401.
1169
1170TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1171 in the DK code in transports.c. sendfile() is not really portable,
1172 hence the _LINUX specificness.
944e9e9c
TF
1173
1174TF/01 In the add_headers option to the mail command in an Exim filter,
1175 there was a bug that Exim would claim a syntax error in any
1176 header after the first one which had an odd number of characters
1177 in the field name.
1178
2b1c6e3a
PH
1179PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1180 callout verification, Exim cached a "reject" for the entire domain. This
1181 is correct for most verifications, but it is not correct for a recipient
1182 verification with use_sender or use_postmaster set, because in that case
1183 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1184 case of MAIL FROM:<> rejection from other early rejections (e.g.
1185 rejection of HELO). When verifying a recipient using a non-null MAIL
1186 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1187 Whatever the result of the callout, the value of the domain cache is
1188 left unchanged (for any other kind of callout, getting as far as trying
1189 RCPT means that the domain itself is ok).

1223PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1224 hostname. This is wrong, because it relates to the incoming message (and
1225 probably the interface on which it is arriving) and not to the outgoing
1226 callout (which could be using a different interface). This has been
1227 changed to use the value of the helo_data option from the smtp transport
1228 instead - this is what is used when a message is actually being sent. If
1229 there is no remote transport (possible with a router that sets up host
1230 addresses), $smtp_active_hostname is used.

14aa5a05 1232PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1233 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1234 (a) The code assumed that strncpy() returns a negative number on buffer
1235 overflow, which isn't the case. Replaced with Exim's string_format()
1236 function.
1237 (b) There were several signed/unsigned issues. I just did the minimum
1238 hacking in of casts. There is scope for a larger refactoring.
1239 (c) The code used strcasecmp() which is not a standard C function.
1240 Replaced with Exim's strcmpic() function.
1241 (d) The code set only $1; it now sets $auth1 as well.
1242 (e) A simple test gave the error "authentication client didn't specify
1243 service in request". It would seem that Dovecot has changed its
1244 interface. Fortunately there's a specification; I followed it and
1245 changed what the client sends and it appears to be working now.

1250PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1251 address A is aliased to B and C, where B exists and C does not. Without
1252 -v the output is "A verified" because verification stops after a
1253 successful redirection if more than one address is generated. However,
1254 with -v the child addresses are also verified. Exim was outputting "A
1255 failed to verify" and then showing the successful verification for C,
1256 with its parentage. It now outputs "B failed to verify", showing B's
1257 parentage before showing the successful verification of C.

1260 look up a TXT record in a specific list after matching in a combined

1262
322050c2
PH
1263PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1264 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1265 they consult the DNS. I had assumed they would set it the way they
1266 wanted; and indeed my experiments on Linux seem to show that in some
1267 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1268 To be on the safe side, however, I have now made the interface to
1269 host_find_byname() similar to host_find_bydns(), with an argument
1270 containing the DNS resolver options. The host_find_byname() function now
1271 sets these options at its start, just as host_find_bydns() does. The smtp
1272 transport options dns_qualify_single and dns_search_parents are passed to
1273 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1274 of host_find_byname() use the default settings of RES_DEFNAMES
1275 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1277PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1278 spool_read_header() do less string testing, by means of a preliminary
1279 switch on the second character of optional "-foo" lines. (This is
1280 overdue, caused by the large number of possibilities that now exist.
1281 Originally there were few.) While I was there, I also converted the
1282 str(n)cmp tests so they don't re-test the leading "-" and the first
1283 character, in the hope this might squeeze out yet more improvement.

PH
1285PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1286 flag allowing group syntax was set by the header_syntax check but not
1287 turned off, possible causing trouble later; (2) The flag was not being
1288 set at all for the header_verify test, causing "group"-style headers to
1289 be rejected. I have now set it in this case, and also caused header_
1290 verify to ignore an empty address taken from a group. While doing this, I
1291 came across some other cases where the code for allowing group syntax
1292 while scanning a header line wasn't quite right (mostly, not resetting
1293 the flag correctly in the right place). These bugs could have caused
1294 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1296PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1297 with the "reply" argument non-NULL. The code, however (which originally
1298 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1299 but it didn't always do it. This confused somebody who was copying the
1300 code for some other use. I have removed all the tests.

411ef850
PH
1302PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1303 feature that was used to support insecure browsers during the U.S. crypto
1304 embargo. It requires special client support, and Exim is probably the
1305 only MTA that supported it -- and would never use it because real RSA is
1306 always available. This code has been removed, because it had the bad
1307 effect of slowing Exim down by computing (never used) parameters for the
1308 RSA_EXPORT functionality.

PH
1310PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1311 authenticator to fail if there's a tab character in the incoming data
1312 (there should never be unless someone is messing about, as it's supposed
1313 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1314 if the connection is using TLS or if the remote IP is the same as the
1315 local IP, and the "valid-client-cert option" if a client certificate has
1316 been verified.

1347
1348PH/30 Exim was sometimes attempting to deliver messages that had suffered
1349 address errors (4xx response to RCPT) over the same connection as other
1350 messages routed to the same hosts. Such deliveries are always "forced",
1351 so retry times are not inspected. This resulted in far too many retries
1352 for the affected addresses. The effect occurred only when there were more
1353 hosts than the hosts_max_try setting in the smtp transport when it had
1354 the 4xx errors. Those hosts that it had tried were not added to the list
1355 of hosts for which the message was waiting, so if all were tried, there
1356 was no problem. Two fixes have been applied:
1357
1358 (i) If there are any address or message errors in an SMTP delivery, none
1359 of the hosts (tried or untried) are now added to the list of hosts
1360 for which the message is waiting, so the message should not be a
1361 candidate for sending over the same connection that was used for a
1362 successful delivery of some other message. This seems entirely
1363 reasonable: after all the message is NOT "waiting for some host".
1364 This is so "obvious" that I'm not sure why it wasn't done
1365 previously. Hope I haven't missed anything, but it can't do any
1366 harm, as the worst effect is to miss an optimization.
1367
1368 (ii) If, despite (i), such a delivery is accidentally attempted, the
1369 routing retry time is respected, so at least it doesn't keep
1370 hammering the server.

1385PH/35 The error "getsockname() failed: connection reset by peer" was being
1386 written to the panic log as well as the main log, but it isn't really
1387 panic-worthy as it just means the connection died rather early on. I have
1388 removed the panic log writing for the ECONNRESET error when getsockname()
1389 fails.
1390
48c7f9e2
PH
1391PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1392 runs only) independently of the message's sender address. This meant
1393 that, if the 4xx error was in fact related to the sender, a different
1394 message to the same recipient with a different sender could confuse
1395 things. In particualar, this can happen when sending to a greylisting
1396 server, but other circumstances could also provoke similar problems.
1397 I have changed the default so that the retry time for these errors is now
1398 based a combination of the sender and recipient addresses. This change
1399 can be overridden by setting address_retry_include_sender=false in the
1400 smtp transport.

1668PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1669 "Deny" causes Exim to reject the incoming connection with a 554 error.
1670 Unfortunately, if there is a major crisis, such as a disk failure,
1671 tcp-wrappers gives "deny", whereas what one would like would be some
1672 kind of temporary error. A kludge has been added to help with this.
1673 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1674 554 error is used if errno is still zero or contains ENOENT (which occurs
1675 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1676 451 error is used.

1712PH/01 The code for finding all the local interface addresses on a FreeBSD
1713 system running IPv6 was broken. This may well have applied to all BSD
1714 systems, as well as to others that have similar system calls. The broken
1715 code found IPv4 interfaces correctly, but gave incorrect values for the
1716 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1717 that it would not match correctly against @[] and not recognize the IPv6
1718 addresses as local.

1761 autoreply, Exim could try to deliver to a non-existent relative file

1783
1784 (a) Failures to set uid/gid, the current directory, or a process leader
1785 in a subprocess such as that created by queryprogram now generate
1786 suitable debugging ouput when -d is set.
1787

1790 the subprocess without attempting to change uid/gid.

1795PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1796 additional section of a DNS packet that returns MX or SRV records.
1797 Instead, it always explicitly searches for A/AAAA records. This avoids
1798 major problems that occur when a DNS server includes only records of one
1799 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1800 fixed another bug: if SRV records were looked up and the corresponding
1801 address records were *not* found in the additional section, the port
1802 values from the SRV records were lost.

1804PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1812PH/19 When calculating a retry time, Exim used to measure the "time since
1813 failure" by looking at the "first failed" field in the retry record. Now
1814 it does not use this if it is later than than the arrival time of the
1815 message. Instead it uses the arrival time. This makes for better
1816 behaviour in cases where some deliveries succeed, thus re-setting the
1817 "first failed" field. An example is a quota failure for a huge message
1818 when small messages continue to be delivered. Without this change, the
1819 "time since failure" will always be short, possible causing more frequent
1820 delivery attempts for the huge message than are intended.

1917PH/42 The content-scanning code uses fopen() to create files in which to put

1920 files with open(), and sets the required mode explicitly. Thus, these
1921 files were ending up world-writeable. This was not a big issue, because,
1922 being within the spool directory, they were not world-accessible. I have
1923 created a function called modefopen, which takes an additional mode
1924 argument. It sets umask(777), creates the file, chmods it to the required
1925 mode, then resets the umask. All the relevant calls to fopen() in the

1964 (i) Exim was not creating retry information for temporary errors given
1965 for individual recipients after the DATA command when the smtp transport
1966 was used in LMTP mode. This meant that they could be retried too
1967 frequently, and not timed out correctly.
1968
1969 (ii) Exim was setting the flag that allows error details to be returned
1970 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1971 recipients that were returned after the DATA command.
1972
1973PH/53 This is related to PH/52, but is more general: for any failing address,
1974 when detailed error information was permitted to be returned to the
1975 sender, but the error was temporary, then after the final timeout, only
1976 "retry timeout exceeded" was returned. Now it returns the full error as
1977 well as "retry timeout exceeded".

2047PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2048 function verify_get_ident() calls ip_connect() to connect a socket, but
2049 if the "connect()" function timed out, ip_connect() used to close the
2050 socket. However, verify_get_ident() also closes the socket later, and in
2051 between Exim writes to the log, which may get opened at this point. When
2052 the socket was closed in ip_connect(), the log could get the same file
2053 descriptor number as the socket. This naturally causes chaos. The fix is
2054 not to close the socket in ip_connect(); the socket should be closed by
2055 the function that creates it. There was only one place in the code where
2056 this was missing, in the iplookup router, which I don't think anybody now
2057 uses, but I've fixed it anyway.

2080
2081 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2082 string.
2083
2084 (3) Reset the variables that are obtained from the first argument of
2085 ${prvscheck and used in the second argument before leaving the code,
2086 because their memory is reclaimed, so using them afterwards may do
2087 silly things.
2088
2089 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2090 one (it's much easier than Tom thought :-).

2113PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2114 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2115 not being looked up in the rDNS to get a host name, Exim was showing the
2116 IP address twice in Received: lines, even though the IP addresses were
2117 identical. For example:
2118
2119 Received: from [1.2.3.4] (helo=[1.2.3.4])
2120
2121 However, if the real host name was known, it was omitting the HELO data
2122 if it matched the actual IP address. This has been tidied up so that it
2123 doesn't show the same IP address twice.

2151
2152 Auto-submitted: auto-generated
2153
2154 in the messages that it generates (bounce messages and others, such as
2155 warnings). In the case of bounce messages for non-SMTP mesages, there was
2156 also a typo: it was using "Auto_submitted" (underscore instead of
2157 hyphen). Since every message generated by Exim is necessarily in response
2158 to another message, thes have all been changed to:
2159
2160 Auto-Submitted: auto-replied
2161
2162 in accordance with these statements in the RFC:
2163
2164 The auto-replied keyword:
2165
2166 - SHOULD be used on messages sent in direct response to another
2167 message by an automatic process,
2168

2212PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2213 canonical form (as documented). However, after a host name lookup from
2214 the IP address, check_host() was doing a simple string comparison with
2215 addresses acquired from the DNS when checking that the found name did
2216 have the original IP as one of its addresses. Since any found IPv6
2217 addresses are likely to be in abbreviated form, the comparison could
2218 fail. Luckily, there already exists a function for doing the comparison
2219 by converting both addresses to binary, so now that is used instead of
2220 the text comparison.

2518 with the definition in sysexits.h (which is #included earlier).
2519 Fortunately, Exim does not actually use EX_OK. The code used to try to
2520 preserve the sysexits.h value, by assumimg that macro definitions were
2521 scanned for macro replacements. I have been disabused of this notion,

2527 This seems wrong - if the receiver was accepting one byte at a time it
2528 would take for ever. The timeout is now adjusted when this happens. It
2529 doesn't have to be particularly precise.

2605 case the guess is not the same as the compiled default, so the script
2606 suddenly stopped working when I started to use syslog. The patch checks
2607 to see if log_file_path is "". If so, it attempts to read it from exim

2609 falls back to the previous guessing code."

2738PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2739 that changes the way the GnuTLS parameters are stored in the cache file.
2740 The new format can be generated externally. For backward compatibility,
2741 if the data in the cache doesn't make sense, Exim assumes it has read an
2742 old-format file, and it generates new data and writes a new file. This
2743 means that you can't go back to an older release without removing the
2744 file.
2745
2746PH/03 A redirect router that has both "unseen" and "one_time" set does not
2747 work if there are any delivery delays because "one_time" forces the
2748 parent to be marked "delivered", so its unseen clone is never tried
2749 again. For this reason, Exim now forbids the simultaneous setting of
2750 these two options.
2751
2752PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2753 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2754 entry if you want to know the details. The fix, however, neglected to
2755 consider the case when local delivery batching is involved. The test for
2756 "previously delivered" was not happening when checking to see if an
2757 address could be batched with a previous (undelivered) one; under
2758 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2759 address.

2768 supplied for verify items that do not have them. (Maybe reverse_host_
2769 lookup should have a defer_ok option, but that's a different point.)
2770
2771PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2823 ownership right at creation (otherwise, other Exim processes might see
2824 the file with the wrong ownership). There was no test for failure of this
2825 fork() call, which would lead to the process getting stuck as it waited
2826 for a non-existent subprocess. Forks do occasionally fail when resources
2827 run out. I reviewed all the other calls to fork(); they all seem to check

2833 the result was a log entry for a synchronization error with an empty
2834 string after "input=" when read() returned zero. If read() returned -1

c5ddb310
PH
2847PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2848 hadn't been configured. The fix is from Juergen Kreileder, who
2849 understands it better than I do:
2850
2851 "Here's what I see happening with three configured cyrus_sasl
2852 authenticators configured (plain, login, cram-md5):
2853
2854 On startup auth_cyrus_sasl_init() gets called for each of these.
2855 This means three calls to sasl_listmech() without a specified mech_list.
2856 => SASL tests which mechs of all available mechs actually work
2857 => three warnings about OTP not working
2858 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2859
2860 With the patch, sasl_listmech() also gets called three times. But now
2861 SASL's mech_list option is set to the server_mech specified in the the
2862 authenticator. Or in other words, the answer from sasl_listmech()
2863 gets limited to just the mech you're testing for (which is different
2864 for each call.)
2865 => the return list contains just 'plain' or 'login', 'cram-md5' or
2866 nothing depending on the value of ob->server_mech.
2867
2868 I've just tested the patch: Authentication still works fine,
2869 unavailable mechs specified in the exim configuration are still
2870 caught, and the auth.log warnings about OTP are gone."

PH
2934PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2935 the grounds that routing the same address twice would always produce the
2936 same answer. This might have been true once, but it is certainly no
2937 longer true now. Routing a child address may depend on the previous
2938 routing that produced that child. Some complicated redirection strategies
2939 went wrong when messages had multiple recipients, and made Exim's
2940 behaviour dependent on the order in which the addresses were given.
2941
2942 I have moved the duplicate checking until after the routing is complete.
2943 Exim scans the addresses that are assigned to local and remote
2944 transports, and removes any duplicates. This means that more work will be
2945 done, as duplicates will always all be routed, but duplicates are
2946 presumably rare, so I don't expect this is of any significance.
2947
2948 For deliveries to pipes, files, and autoreplies, the duplicate checking
2949 still happens during the routing process, since they are not going to be
2950 routed further.

2995 consistency with the overall process timeout, these timeouts are now
2996 treated as errors, giving rise to delivery failures by default. However,
2997 there is now a new Boolean option for the pipe transport called

3009A note about Exim versions 4.44 and 4.50
3010----------------------------------------
3011
3012Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3013changes of various kinds. As a consequence, a big documentation update was
3014needed. This delayed the release for rather longer than seemed good, especially
3015in the light of a couple of (minor) security issues. Therefore, the changes
3016that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3017release. So 4.44 and 4.50 are in effect two different branches that both start
3018from 4.43.
3019
3020I have left the 4.50 change log unchanged; it contains all the changes since
30214.43. The change log for 4.44 is below; many of its items are identical to
3022those for 4.50. This seems to be the most sensible way to preserve the
3023historical information.

3041 5. There are several places where Exim runs a non-Exim command in a
3042 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3043 was being done only for the command run by the queryprogram router. It is
3044 now done for all such subprocesses. The other cases are: ${run, transport
3045 filters, and the commands run by the lmtp and pipe transports.

3050 descriptors. Exim was using setrlimit() to set 1000 as a large value
3051 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3052 systems. I've change it so that if it can't get 1000, it tries for 256.

3101
310223. When checking ignore_target_hosts for an ipliteral router, no host name was
3103 being passed; this would have caused $sender_host_name to have been used if

3106 "[x.x.x.x]".

3111
311225. Narrowed the window for a race in the daemon that could cause it to ignore

312629. In an address list, if the pattern was not a regular expression, an empty
3127 subject address (from a bounce message) matched only if the pattern was an
3128 empty string. Non-empty patterns were not even tested. This was the wrong
3129 because it is perfectly reasonable to use an empty address as part of a
3130 database query. An empty address is now tested by patterns that are
3131 lookups. However, all the other forms of pattern expect the subject to
3132 contain a local part and a domain, and therefore, for them, an empty
3133 address still always fails if the pattern is not itself empty.

314432. The RFC2047 encoding function was originally intended for short strings
3145 such as real names; it was not keeping to the 75-character limit for
3146 encoded words that the RFC imposes. It now respects the limit, and
3147 generates multiple encoded words if necessary. To be on the safe side, I
3148 have increased the buffer size for the ${rfc2047: expansion operator from
3149 1024 to 2048 bytes.

3154 cumbersome to write custom ACL and router conditions.

PH
316436. The table in the code that translates DNS record types into text (T_A to
3165 "A" for instance) was missing entries for NS and CNAME. It is just possible
3166 that this could have caused confusion if both these types were looked up
3167 for the same domain, because the text type is used as part of Exim's
3168 per-process caching. But the chance of anyone hitting this buglet seems
3169 very small.
3170
7bb56e1f
PH
317137. The dnsdb lookup has been extended in a number of ways.
3172
3173 (1) There is a new type, "zns", which walks up the domain tree until it
3174 finds some nameserver records. It should be used with care.
3175
ea3bc19b
PH
3176 (2) There is a new type, "mxh", which is like "mx" except that it returns
3177 just the host names, not the priorities.
3178
3179 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3180 looked up. The behaviour when one of the lookups defers can be
3181 controlled by a keyword.
7bb56e1f 3182
ea3bc19b 3183 (4) It is now possible to specify the separator character for use when
7bb56e1f 3184 multiple records are returned.
33397d19 3185
0bcb2a0e
PH
318638. The dnslists ACL condition has been extended: it is now possible to supply
3187 a list of IP addresses and/or domains to be looked up in a particular DNS
3188 domain.

PH
319039. Added log_selector=+queue_time_overall.
3191
4e1fde53
PH
319240. When running the queue in the test harness, wait just a tad after forking a
3193 delivery process, to get repeatability of debugging output.
3194
de365ded
PH
319541. Include certificate and key file names in error message when GnuTLS fails
3196 to set them up, because the GnuTLS error message doesn't include the name
3197 of the failing file when there is a problem reading it.
3198

PH
319942. Allow both -bf and -bF in the same test run.

PH
320143. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3202
f7b63901
PH
320344. The "Exiscan patch" is now merged into the mainline Exim source.
3204
320545. Sometimes the final signoff response after QUIT could fail to get
3206 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3207 < 0 before doing a fflush(). This bug looks as though it goes back to the
3208 introduction of TLS in release 3.20, but "sometimes" must have been rare
3209 because the tests only now provoked it.
3210

PH
321146. Reset the locale to "C" after calling embedded Perl, in case it was changed
3212 (this can affect the format of dates).
3213
0ec020ea
PH
321447. exim_tidydb, when checking for the continued existence of a message for
3215 which it has found a message-specific retry record, was not finding
3216 messages that were in split spool directories. Consequently, it was
3217 deleting retry records that should have stayed in existence.
3218
b1206957
PH
321948. Steve fixed some bugs in eximstats.
3220
322149. The SPA authentication driver was not abandoning authentication and moving
3222 on to the next authenticator when an expansion was forced to fail,
3223 contradicting the general specification for all authenticators. Instead it
3224 was generating a temporary error. It now behaves as specified.
3225
26dd5a95
PH
322650. The default ordering of permitted cipher suites for GnuTLS was pessimal
3227 (the order specifies the preference for clients). The order is now AES256,
3228 AES128, 3DES, ARCFOUR128.
3229
343b2385
PH
323051. Small patch to Sieve code - explicitly set From: when generating an
3231 autoreply.
3232
1c5466b9
PH
323352. Exim crashed if a remote delivery caused a very long error message to be
3234 recorded - for instance if somebody sent an entire SpamAssassin report back
3235 as a large number of 550 error lines. This bug was coincidentally fixed by
3236 increasing the size of one of Exim's internal buffers (big_buffer) that
3237 happened as part of the Exiscan merge. However, to be on the safe side, I
3238 have made the code more robust (and fixed the comments that describe what
3239 is going on).
3240
55ee9ee3
PH
324153. Now that there can be additional text after "Completed" in log lines (if
3242 the queue_time_overall log selector is set), a one-byte patch to exigrep
3243 was needed to allow it to recognize "Completed" as not the last thing in
3244 the line.
3245

PH
324654. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3247 patch that reportedly fixes this has been added. I am not expert enough to
3248 create a test for it. This is what the patch creator wrote:
3249
3250 "I found a little strange behaviour of ldap code when working with
3251 Windows 2003 AD Domain, where users was placed in more than one
3252 Organization Units. When I tried to give exim partial DN, the exit code
3253 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3254 But simultaneously result of request was absolutely normal ldap result,
3255 so I produce this patch..."
3256
3295e65b
PH
3257 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3258 REFERENCE, so I have modified the code to exclude the patch when that macro
3259 is not defined.
3260
7102e136
PH
326155. Some experimental protocols are using DNS PTR records for new purposes. The
3262 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3263 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3264 leaves it alone. Component reversal etc. now happens only for IP addresses.

326957. Double the size of the debug message buffer (to 2048) so that more of very
3270 long debug lines gets shown.
3271
18ce445d
PH
327258. The exicyclog utility now does better if the number of log files to keep
3273 exceeds 99. In this case, it numbers them 001, 002 ... instead of 01, 02...
3274

PH
327559. Two changes related to the smtp_active_hostname option:
3276
3277 (1) $smtp_active_hostname is now available as a variable.
3278 (2) The default for smtp_banner uses $smtp_active_hostname instead
3279 of $primary_hostname.
3280
b975ba52
PH
328160. The host_aton() function is supposed to be passed a string that is known
3282 to be a valid IP address. However, in the case of IPv6 addresses, it was
3283 not checking this. This is a hostage to fortune. Exim now panics and dies
3284 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3285 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3286 components; fortuitously, this particular loophole had already been fixed
3287 by change 4.50/55 above.
3288
3289 If there are any other similar loopholes, the new check in host_aton()
3290 itself should stop them being exploited. The report I received stated that
3291 data on the command line could provoke the exploit when Exim was running as
3292 exim, but did not say which command line option was involved. All I could
3293 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3294 running as the user.

329761. There was a buffer overflow vulnerability in the SPA authentication code
3298 (which came originally from the Samba project). I have added a test to the
3299 spa_base64_to_bits() function which I hope fixes it.

330262. Configuration update for GNU/Hurd and variations. Updated Makefile-GNU and
3303 os.h-GNU, and added configuration files for GNUkFreeBSD and GNUkNetBSD.
3304
d95f9fdb
PH
330563. The daemon start-up calls getloadavg() while still root for those OS that
3306 need the first call to be done as root, but it missed one case: when
3307 deliver_queue_load_max is set with deliver_drop_privilege. This is
3308 necessary for the benefit of the queue runner, because there is no re-exec
3309 when deliver_drop_privilege is set.
3310
86b8287f
PH
331164. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3312 This has been fixed.
3313
60dc5e56
PH
331465. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3315 was in use, was not putting the data itself into the right store pool;
3316 consequently, it could be overwritten for a subsequent message in the same
3317 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3318 the caching.)
3319
533244af
PH
332066. Added hosts_max_try_hardlimit to the smtp transport, default 50.
3321
a5a28604
PH
332267. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3323 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3324 the function were treating the return as a boolean value, which happened to
3325 work because 0=false and not-0=true, but is not correct code.
3326
7e634d24
PH
332768. The host_aton() function was not handling scoped IPv6 addresses (those
3328 with, for example, "%eth0" on the end) correctly.
3329
3e11c26b
PH
333069. Fixed some compiler warnings in acl.c for the bitmaps specified with
3331 negated items (that is, ~something) in unsigned ints. Some compilers
3332 apparently mutter when there is no cast.
3333
6729cf78
PH
333470. If an address verification called from an ACL failed, and did not produce a
3335 user-specific message (i.e. there was only a "system" message), nothing was
3336 put in $acl_verify_message. In this situation, it now puts the system
3337 message there.
3338
00f00ca5
PH
333971. Change 4.23/11 added synchronization checking at the start of an SMTP
3340 session; change 4.31/43 added the unwanted input to the log line - except
3341 that it did not do this in the start of session case. It now does.
3342
c9bdd01c
PH
334372. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3344 This is wrong and can cause the other end to generate a synchronization
3345 error if it is another Exim or anything else that does the synchronization
3346 check. A QUIT command is no longer sent after a timeout.
3347
d43194df
PH
334873. $host_lookup_deferred has been added, to make it easier to detect DEFERs
3349 during host lookups.
3350
fe5b5d0b
PH
335174. The defer_ok option of callout verification was not working if it was used
3352 when verifying addresses in header lines, that is, for this case:
3353
3354 verify = header_sender/callout=defer_ok
3355
76a2d7ba
PH
335675. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
3357 those file descriptors could be used for SMTP connections. If anything
3358 wrote to stderr (the example that came up was "warn" in embedded Perl), it
3359 could be sent to the SMTP client, causing chaos. The daemon now opens
3360 stdin, stdout, and stderr to /dev/null when it puts itself into the
3361 background.
3362
336376. Arrange for output from Perl's "warn" command to be written to Exim's main
3364 log by default. The user can override this with suitable Perl magic.
3365
04f7d5b9
PH
336677. The use of log_message on a "discard" ACL verb, which is supposed to add to
3367 the log message when discard triggers, was not working for the DATA ACL or
3368 for the non-SMTP ACL.
3369
bc60667e
PH
337078. Error message wording change in sieve.c.
3371
bb6e88ff
PH
337279. If smtp_accept_max_per_host was set, the number of connections could be
3373 restricted to fewer than expected, because the daemon was trying to set up
3374 a new connection before checking whether the processes handling previous
3375 connections had finished. The check for completed processes is now done
3376 earlier. On busy systems, this bug wouldn't be noticed because something
3377 else would have woken the daemon, and it would have reaped the completed
3378 process earlier.
3379
1e70f85b
PH
338080. If a message was submitted locally by a user whose login name contained one
3381 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
3382 It caused a spool format error. I have fixed the spool reading code. A
3383 related problem was that the "from" clause in the Received: line became
3384 illegal because of the space(s). It is now covered by ${quote_local_part.
