104PP/19 DNS resolver init changes for NetBSD compatibility. (Risk of breakage
105 on less well tested platforms). Obviates NetBSD pkgsrc patch-ac.
106 Not seeing resolver debug output on NetBSD, but suspect this is a
107 resolver implementation change.

97d17305
JH
123 This may cause build issues on older platforms.
124
17c76198
PP
125PP/25 Revamped GnuTLS support, passing tls_require_ciphers to
126 gnutls_priority_init, ignoring Exim options gnutls_require_kx,
127 gnutls_require_mac & gnutls_require_protocols (no longer supported).
128 Added SNI support via GnuTLS too.
af3498d6 129 Made ${randint:..} supplier available, if using not-too-old GnuTLS.

143PP/29 Fix three issues highlighted by clang analyser static analysis.
144 Only crash-plausible issue would require the Cambridge-specific
145 iplookup router and a misconfiguration.

PP
148PP/30 Another attempt to deal with PCRE_PRERELEASE, this one less buggy.
149
81f91683
PP
150PP/31 %D in printf continues to cause issues (-Wformat=security), so for
151 now guard some of the printf checks behind WANT_DEEPER_PRINTF_CHECKS.
152 As part of this, removing so much warning spew let me fix some minor
153 real issues in debug logging.
154
5779e6aa
PP
155PP/32 GnuTLS was always using default tls_require_ciphers, due to a missing
156 assignment on my part. Fixed.
157
3375e053
PP
158PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit
159 of NSS, for GnuTLS/NSS interop. Problem root cause diagnosis by
160 Janne Snabb (who went above and beyond: thank you).
161
162PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
163 string otherwise requires a connection and a bunch more work and it's
78e0c7a3
PP
164 relatively easy to get wrong. Should also expose TLS library linkage
165 problems.

b87a6e0e
PP
171 GNU libc to support some of the 64-bit stuff, should not lead to
172 conflicts. Defined before os.h is pulled in, so if a given platform
173 needs to override this, it can.
174
16880d1a
PP
175PP/37 Unbreak Cyrus SASL auth: SSF retrieval was incorrect, Exim thought
176 protection layer was required, which is not implemented.
177 Bugzilla 1254, patch from Wolfgang Breyha.
178
a799883d
PP
179PP/38 Overhaul DH prime handling, supply RFC-specified DH primes as built
180 into Exim, default to IKE id 23 from RFC 5114 (2048 bit). Make
181 tls_dhparam take prime identifiers. Also unbreak combination of
182 OpenSSL+DH_params+TLSSNI.
183
3ecab157 184PP/39 Disable SSLv2 by default in OpenSSL support.

TF
201TF/03 Make the exiwhat support code safe for signals. Previously Exim might
202 lock up or crash if it happened to be inside a call to libc when it
203 got a SIGUSR1 from exiwhat.
204
205 The SIGUSR1 handler appends the current process status to the process
206 log which is later printed by exiwhat. It used to use the general
207 purpose logging code to do this, but several functions it calls are
208 not safe for signals.
209
210 The new output code in the SIGUSR1 handler is specific to the process
211 log, and simple enough that it's easy to inspect for signal safety.
212 Removing some special cases also simplifies the general logging code.
213 Removing the spurious timestamps from the process log simplifies
214 exiwhat.
215
c99ce5c9
TF
216TF/04 Improved ratelimit ACL condition.
217
218 The /noupdate option has been deprecated in favour of /readonly which
219 has clearer semantics. The /leaky, /strict, and /readonly update modes
220 are mutually exclusive. The update mode is no longer included in the
221 database key; it just determines when the database is updated. (This
222 means that when you upgrde Exim will forget old rate measurements.)
223
224 Exim now checks that the per_* options are used with an update mode that
225 makes sense for the current ACL. For example, when Exim is processing a
226 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
227 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
228 must specify per_mail/readonly. If you omit the update mode it defaults to
229 /leaky where that makes sense (as before) or /readonly where required.
230
231 The /noupdate option is now undocumented but still supported for
232 backwards compatibility. It is equivalent to /readonly except that in
233 ACLs where /readonly is required you may specify /leaky/noupdate or
234 /strict/noupdate which are treated the same as /readonly.
235
236 A useful new feature is the /count= option. This is a generalization
237 of the per_byte option, so that you can measure the throughput of other
238 aggregate values. For example, the per_byte option is now equivalent
239 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
240
241 The per_rcpt option has been generalized using the /count= mechanism
242 (though it's more complicated than the per_byte equivalence). When it is
243 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
244 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
245 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
246 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
247 Note that using per_rcpt with a non-readonly update mode in more than
248 one ACL will cause the recipients to be double-counted. (The per_mail
249 and per_byte options don't have this problem.)
250
251 The handling of very low rates has changed slightly. If the computed rate
252 is less than the event's count (usually one) then this event is the first
253 after a long gap. In this case the rate is set to the same as this event's
254 count, so that the first message of a spam run is counted properly.
255
256 The major new feature is a mechanism for counting the rate of unique
257 events. The new per_addr option counts the number of different
258 recipients that someone has sent messages to in the last time period. It
259 behaves like per_rcpt if all the recipient addresses are different, but
260 duplicate recipient addresses do not increase the measured rate. Like
261 the /count= option this is a general mechanism, so the per_addr option
262 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
263 example, measure the rate that a client uses different sender addresses
264 with the options per_mail/unique=$sender_address. There are further
265 details in the main documentation.

811TK/01 Add preliminary DKIM support. Currently requires a forked version of
812 ALT-N's libdkim that I have put here:
813 http://duncanthrax.net/exim-experimental/
814
815 Note to Michael Haardt: I had to rename some vars in sieve.c. They
816 were called 'true' and it seems that C99 defines that as a reserved
817 keyword to be used with 'bool' variable types. That means you could
818 not include C99-style headers which use bools without triggering
819 build errors in sieve.c.

837PH/01 Another patch from the Sieve maintainer.
838
6a3bceb1
PH
839PH/02 When an IPv6 address is converted to a string for single-key lookup
840 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
841 dots are used instead of colons so that keys in lsearch files need not
842 contain colons. This was done some time before quoting was made available
843 in lsearch files. However, iplsearch files do require colons in IPv6 keys
844 (notated using the quote facility) so as to distinguish them from IPv4
845 keys. This meant that lookups for IP addresses in host lists did not work
846 for iplsearch lookups.
847
848 This has been fixed by arranging for IPv6 addresses to be expressed with
849 colons if the lookup type is iplsearch. This is not incompatible, because
850 previously such lookups could never work.
851
852 The situation is now rather anomolous, since one *can* have colons in
853 ordinary lsearch keys. However, making the change in all cases is
854 incompatible and would probably break a number of configurations.
855
2e30fa9d
TK
856TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
857 version.
858

MH
859MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
860 conversion specification without a maximum field width, thereby enabling
861 a rogue spamd server to cause a buffer overflow. While nobody in their
862 right mind would setup Exim to query an untrusted spamd server, an
863 attacker that gains access to a server running spamd could potentially
864 exploit this vulnerability to run arbitrary code as the Exim user.

866TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
867 $primary_hostname instead of what libspf2 thinks the hosts name is.
868
0f2cbd1b
MH
869MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
870 a directory entry by the name of the lookup key. Previously, if a
871 symlink pointed to a non-existing file or a file in a directory that
872 Exim lacked permissions to read, a lookup for a key matching that
873 symlink would fail. Now it is enough that a matching directory entry
874 exists, symlink or not. (Bugzilla 503.)
875

880
6c512171
PH
881PH/05 Unset $tls_cipher and $tls_peerdn before making a connection as a client.
882 This means they are set thereafter only if the connection becomes
883 encrypted.
884
885PH/06 Added the client_condition to authenticators so that some can be skipped
886 by clients under certain conditions.

888PH/07 The error message for a badly-placed control=no_multiline_responses left
889 "_responses" off the end of the name.

894 (without spaces) instead of just copying the configuration text.

903 way in which PCRE > 7.0 is built.

PH
914PH/18 If a system quota error occurred while trying to create the file for
915 a maildir delivery, the message "Mailbox is full" was not appended to the
916 bounce if the delivery eventually timed out. Change 4.67/27 below applied
917 only to a quota excession during the actual writing of the file.
d6a60c0f 918
ddea74fa 919PH/19 It seems that peer DN values may contain newlines (and other non-printing
48ed62d9
PH
920 characters?) which causes problems in log lines. The DN values are now
921 passed through string_printing() before being added to log lines.
922

b7670459

940MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
941 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
942 Jan Srzednicki.
943
b4ed4da0
PH
944PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
945 issue a MAIL command.
946
431b7361
PH
947PH/02 In an ACL statement such as
948
949 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
950
951 if a client was not listed at all, or was listed with a value other than
952 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
953 the condition was not true (as it should be), so access was not denied.
954 The bug was that the ! inversion was incorrectly passed on to the second
955 item. This has been fixed.
956
957PH/03 Added additional dnslists conditions == and =& which are different from
958 = and & when the dns lookup returns more than one IP address.
959
83da1223
PH
960PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
961 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
962
54fc8428
PH
963PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
964 FSYNC, which compiles an option called disable_fsync that allows for
965 bypassing fsync(). The documentation is heavily laced with warnings.

PH
969PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
970 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
971 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
972 including adding "make clean"; (3) Added -fPIC when compiling the test
973 dynamically loaded module, to get rid of a warning.
974
0e8a9471
MH
975MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
976 message fails, move_frozen_messages = true and ignore_bounce_errors_after
977 = 0s. The bug is otherwise harmless.
978
f0872424
PH
979PH/07 There was a bug in the dovecot authenticator such that the value of
980 $auth1 could be overwritten, and so not correctly preserved, after a
981 successful authentication. This usually meant that the value preserved by
982 the server_setid option was incorrect.
983
b01dd148
PH
984PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.

987
273f34d0
PH
988PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
989 run for batched SMTP input. It is now run at the start of every message
990 in the batch. While fixing this I discovered that the process information
991 (output by running exiwhat) was not always getting set for -bs and -bS
992 input. This is fixed, and it now also says "batched" for BSMTP.
993
cf8b11a5
PH
994PH/11 Added control=no_pipelining.
995
41c7c167
PH
996PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
997 patch, slightly modified), and move the expansion of helo_data till after
998 the connection is made in the smtp transport (so it can use these
999 values).

09945f1e
PH
1014PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
1015 was true (the default) a successful delivery failed to delete the retry
1016 item, thus causing premature timeout of the address. The bug is now
1017 fixed.
1018
c51b8e75
PH
1019PH/20 Added hosts_avoid_pipelining to the smtp transport.
1020
e28326d8
PH
1021PH/21 Long custom messages for fakedefer and fakereject are now split up
1022 into multiline reponses in the same way that messages for "deny" and
1023 other ACL rejections are.

75b1493f
PH
1025PH/22 Applied Jori Hamalainen's speed-up changes and typo fixes to exigrep,
1026 with slight modification.

1028PH/23 Applied sieve patches from the maintainer "tracking the latest notify
1029 draft, changing the syntax and factoring some duplicate code".
1030
4311097e
PH
1031PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
1032 for deliveries of the second and subsequent messages over the same SMTP
1033 connection.

29f89cad
PH
1035PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
1036 ${reduce, with only minor "tidies".

SC
1038SC/02 Applied Daniel Tiefnig's patch to improve the '($parent) =' pattern match.
1039
c3611384
PH
1040PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
1041 expansion side effects.
1042
5a11a7b4
PH
1043PH/27 When a message times out after an over-quota error from an Exim-imposed
1044 quota, the bounce message says "mailbox is full". This message was not
1045 being given when it was a system quota that was exceeded. It now should
1046 be the same.
1047
0e20aff9
MH
1048MH/03 Made $recipients available in local_scan(). local_scan() already has
1049 better access to the recipient list through recipients_list[], but
1050 $recipients can be useful in postmaster-provided expansion strings.
1051
ca86f471
PH
1052PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1053 in the case of a MAIL command with additional options following the
1054 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1055 were accidentally chopped off.
1056
a14e5636
PH
1057PH/29 SMTP synchronization checks are implemented when a command is read -
1058 there is a check that no more input is waiting when there shouldn't be
1059 any. However, for some commands, a delay in an ACL can mean that it is
1060 some time before the response is written. In this time, more input might
1061 arrive, invalidly. So now there are extra checks after an ACL has run for
1062 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1063 pipelining has not been advertised.
1064
ec95d1a6
PH
1065PH/30 MH's patch to allow iscntrl() characters to be list separators.
1066
42855d71
PH
1067PH/31 Unlike :fail:, a custom message specified with :defer: was not being
1068 returned in the SMTP response when smtp_return_error_details was false.
1069 This has been fixed.
1070
57c2c631
PH
1071PH/32 Change the Dovecot authenticator to use read() and write() on the socket
1072 instead of the C I/O that was originally supplied, because problems were
1073 reported on Solaris.
1074
58c01c94
PH
1075PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1076 Exim which did not show up earlier: it was assuming that a call to
1077 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1078 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1079 was a macro that became an assignment, so it seemed to work. This has
1080 changed to a proper function call with a void return, hence the compile
1081 error. Exim's code has been fixed.
1082
dee5a20a
PH
1083PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
1084 cpus.
1085
d2ee6114
PH
1086PH/35 Applied a patch from the Sieve maintainer which fixes a bug in "notify".
1087
b2d5182b
PH
1088PH/36 Applied John Jetmore's patch to add -v functionality to exigrep.
1089
79749a79
PH
1090PH/37 If a message is not accepted after it has had an id assigned (e.g.
1091 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
1092 "Completed" line in the log. When some messages of this type were
1093 selected by exigrep, they were listed as "not completed". Others were
1094 picked up by some special patterns. I have improved the selection
1095 criteria to be more general.
79749a79 1096
c456d9bb
PH
1097PH/38 The host_find_failed option in the manualroute router can now be set
1098 to "ignore", to completely ignore a host whose IP address cannot be
1099 found. If all hosts are ignored, the behaviour is controlled by the new
1100 host_all_ignored option.
1101
cd9868ec
PH
1102PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1103 homing or because of multiple MX records with /mx) generated more than
1104 one IP address, and the following item turned out to be the local host,
1105 all the secondary addresses of the first item were incorrectly removed
1106 from the list, along with the local host and any following hosts (which
1107 is what is supposed to happen).
1108
ebeaf996
PH
1109PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1110 whoever called Exim into the -H file. In the case of the daemon it was
1111 behaving confusingly. When first started, it used values for whoever
1112 started the daemon, but after a SIGHUP it used the Exim user (because it
1113 calls itself on a restart). I have changed the code so that it now always
1114 uses the Exim user.
1115
2679d413
PH
1116PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1117 message are rejected with the same error (e.g. no authentication or bad
1118 sender address), and a DATA command is nevertheless sent (as can happen
1119 with PIPELINING or a stupid MUA), the error message that was given to the
1120 RCPT commands is included in the rejection of the DATA command. This is
1121 intended to be helpful for MUAs that show only the final error to their
1122 users.

1135
58eb016e 1136PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1137 the response to the final '.' that terminates a message, but only in the
1138 case where the client has not sent further data following the '.'
1139 (unfortunately, this is allowed). However, in many cases there won't be
1140 any further data because there won't be any more messages to send. A call
1141 to select() can be used: if it shows that the input is "ready", there is
1142 either input waiting, or the socket has been closed. An attempt to read
1143 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1144 would have sent an OK response which the client would never have see.
563b63fa
PH
1145 This could lead to message repetition. This fix should cure that, at
1146 least in a lot of common cases.

1152Exim version 4.66
1153-----------------
1154
1155PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1156 fixed by 4.65/MH/01 (is this a record?) are fixed:
1157
1158 (i) An empty string was always treated as zero by the numeric comparison
1159 operators. This behaviour has been restored.
1160
1161 (ii) It is documented that the numeric comparison operators always treat
1162 their arguments as decimal numbers. This was broken in that numbers
1163 starting with 0 were being interpreted as octal.
1164
1165 While fixing these problems I realized that there was another issue that
1166 hadn't been noticed. Values of message_size_limit (both the global option
1167 and the transport option) were treated as octal if they started with 0.
1168 The documentation was vague. These values are now always treated as
1169 decimal, and I will make that clear in the documentation.

MH
1179MH/01 Don't check that the operands of numeric comparison operators are

4362ff0d
PH
1183PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1184 child addresses, Exim now panics and dies. Previously, because the count
1185 is held in a short int, deliveries were likely to be lost. As such a
1186 large number of recipients for a single message is ridiculous
1187 (performance will be very, very poor), I have chosen to impose a limit
1188 rather than extend the field.

1195 leftover -K file (the existence of which was triggered by #402).
1196 While we were at it, introduced process PID as part of the -K
1197 filename. This should rule out race conditions when creating
1198 these files.

1200TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1201 processing considerably. Previous code took too long for large mails,
1202 triggering a timeout which in turn triggers #401.
1203
1204TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1205 in the DK code in transports.c. sendfile() is not really portable,
1206 hence the _LINUX specificness.

1208TF/01 In the add_headers option to the mail command in an Exim filter,
1209 there was a bug that Exim would claim a syntax error in any
1210 header after the first one which had an odd number of characters
1211 in the field name.

PH
1213PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1214 callout verification, Exim cached a "reject" for the entire domain. This
1215 is correct for most verifications, but it is not correct for a recipient
1216 verification with use_sender or use_postmaster set, because in that case
1217 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1218 case of MAIL FROM:<> rejection from other early rejections (e.g.
1219 rejection of HELO). When verifying a recipient using a non-null MAIL
1220 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1221 Whatever the result of the callout, the value of the domain cache is
1222 left unchanged (for any other kind of callout, getting as far as trying
1223 RCPT means that the domain itself is ok).

1257PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1258 hostname. This is wrong, because it relates to the incoming message (and
1259 probably the interface on which it is arriving) and not to the outgoing
1260 callout (which could be using a different interface). This has been
1261 changed to use the value of the helo_data option from the smtp transport
1262 instead - this is what is used when a message is actually being sent. If
1263 there is no remote transport (possible with a router that sets up host
1264 addresses), $smtp_active_hostname is used.

14aa5a05 1266PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1267 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1268 (a) The code assumed that strncpy() returns a negative number on buffer
1269 overflow, which isn't the case. Replaced with Exim's string_format()
1270 function.
1271 (b) There were several signed/unsigned issues. I just did the minimum
1272 hacking in of casts. There is scope for a larger refactoring.
1273 (c) The code used strcasecmp() which is not a standard C function.
1274 Replaced with Exim's strcmpic() function.
1275 (d) The code set only $1; it now sets $auth1 as well.
1276 (e) A simple test gave the error "authentication client didn't specify
1277 service in request". It would seem that Dovecot has changed its
1278 interface. Fortunately there's a specification; I followed it and
1279 changed what the client sends and it appears to be working now.

PH
1284PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1285 address A is aliased to B and C, where B exists and C does not. Without
1286 -v the output is "A verified" because verification stops after a
1287 successful redirection if more than one address is generated. However,
1288 with -v the child addresses are also verified. Exim was outputting "A
1289 failed to verify" and then showing the successful verification for C,
1290 with its parentage. It now outputs "B failed to verify", showing B's
1291 parentage before showing the successful verification of C.

1294 look up a TXT record in a specific list after matching in a combined

1296
322050c2
PH
1297PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1298 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1299 they consult the DNS. I had assumed they would set it the way they
1300 wanted; and indeed my experiments on Linux seem to show that in some
1301 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1302 To be on the safe side, however, I have now made the interface to
1303 host_find_byname() similar to host_find_bydns(), with an argument
1304 containing the DNS resolver options. The host_find_byname() function now
1305 sets these options at its start, just as host_find_bydns() does. The smtp
1306 transport options dns_qualify_single and dns_search_parents are passed to
1307 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1308 of host_find_byname() use the default settings of RES_DEFNAMES
1309 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1311PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1312 spool_read_header() do less string testing, by means of a preliminary
1313 switch on the second character of optional "-foo" lines. (This is
1314 overdue, caused by the large number of possibilities that now exist.
1315 Originally there were few.) While I was there, I also converted the
1316 str(n)cmp tests so they don't re-test the leading "-" and the first
1317 character, in the hope this might squeeze out yet more improvement.
1318

PH
1319PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1320 flag allowing group syntax was set by the header_syntax check but not
1321 turned off, possible causing trouble later; (2) The flag was not being
1322 set at all for the header_verify test, causing "group"-style headers to
1323 be rejected. I have now set it in this case, and also caused header_
1324 verify to ignore an empty address taken from a group. While doing this, I
1325 came across some other cases where the code for allowing group syntax
1326 while scanning a header line wasn't quite right (mostly, not resetting
1327 the flag correctly in the right place). These bugs could have caused
1328 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1330PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1331 with the "reply" argument non-NULL. The code, however (which originally
1332 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1333 but it didn't always do it. This confused somebody who was copying the
1334 code for some other use. I have removed all the tests.

411ef850
PH
1336PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1337 feature that was used to support insecure browsers during the U.S. crypto
1338 embargo. It requires special client support, and Exim is probably the
1339 only MTA that supported it -- and would never use it because real RSA is
1340 always available. This code has been removed, because it had the bad
1341 effect of slowing Exim down by computing (never used) parameters for the
1342 RSA_EXPORT functionality.

7befa435
PH
1344PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1345 authenticator to fail if there's a tab character in the incoming data
1346 (there should never be unless someone is messing about, as it's supposed
1347 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1348 if the connection is using TLS or if the remote IP is the same as the
1349 local IP, and the "valid-client-cert option" if a client certificate has
1350 been verified.

1381
1382PH/30 Exim was sometimes attempting to deliver messages that had suffered
1383 address errors (4xx response to RCPT) over the same connection as other
1384 messages routed to the same hosts. Such deliveries are always "forced",
1385 so retry times are not inspected. This resulted in far too many retries
1386 for the affected addresses. The effect occurred only when there were more
1387 hosts than the hosts_max_try setting in the smtp transport when it had
1388 the 4xx errors. Those hosts that it had tried were not added to the list
1389 of hosts for which the message was waiting, so if all were tried, there
1390 was no problem. Two fixes have been applied:
1391
1392 (i) If there are any address or message errors in an SMTP delivery, none
1393 of the hosts (tried or untried) are now added to the list of hosts
1394 for which the message is waiting, so the message should not be a
1395 candidate for sending over the same connection that was used for a
1396 successful delivery of some other message. This seems entirely
1397 reasonable: after all the message is NOT "waiting for some host".
1398 This is so "obvious" that I'm not sure why it wasn't done
1399 previously. Hope I haven't missed anything, but it can't do any
1400 harm, as the worst effect is to miss an optimization.
1401
1402 (ii) If, despite (i), such a delivery is accidentally attempted, the
1403 routing retry time is respected, so at least it doesn't keep
1404 hammering the server.

PH
1419PH/35 The error "getsockname() failed: connection reset by peer" was being
1420 written to the panic log as well as the main log, but it isn't really
1421 panic-worthy as it just means the connection died rather early on. I have
1422 removed the panic log writing for the ECONNRESET error when getsockname()
1423 fails.
1424
48c7f9e2
PH
1425PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1426 runs only) independently of the message's sender address. This meant
1427 that, if the 4xx error was in fact related to the sender, a different
1428 message to the same recipient with a different sender could confuse
1429 things. In particualar, this can happen when sending to a greylisting
1430 server, but other circumstances could also provoke similar problems.
1431 I have changed the default so that the retry time for these errors is now
1432 based a combination of the sender and recipient addresses. This change
1433 can be overridden by setting address_retry_include_sender=false in the
1434 smtp transport.

1704 Unfortunately, if there is a major crisis, such as a disk failure,
1705 tcp-wrappers gives "deny", whereas what one would like would be some
1706 kind of temporary error. A kludge has been added to help with this.
1707 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1708 554 error is used if errno is still zero or contains ENOENT (which occurs
1709 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1710 451 error is used.

1749 code found IPv4 interfaces correctly, but gave incorrect values for the
1750 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1751 that it would not match correctly against @[] and not recognize the IPv6
1752 addresses as local.

1795 autoreply, Exim could try to deliver to a non-existent relative file

1818 (a) Failures to set uid/gid, the current directory, or a process leader
1819 in a subprocess such as that created by queryprogram now generate
1820 suitable debugging ouput when -d is set.

1824 the subprocess without attempting to change uid/gid.

1830 additional section of a DNS packet that returns MX or SRV records.
1831 Instead, it always explicitly searches for A/AAAA records. This avoids
1832 major problems that occur when a DNS server includes only records of one
1833 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1834 fixed another bug: if SRV records were looked up and the corresponding
1835 address records were *not* found in the additional section, the port
1836 values from the SRV records were lost.

1838PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1846PH/19 When calculating a retry time, Exim used to measure the "time since
1847 failure" by looking at the "first failed" field in the retry record. Now
1848 it does not use this if it is later than than the arrival time of the
1849 message. Instead it uses the arrival time. This makes for better
1850 behaviour in cases where some deliveries succeed, thus re-setting the
1851 "first failed" field. An example is a quota failure for a huge message
1852 when small messages continue to be delivered. Without this change, the
1853 "time since failure" will always be short, possible causing more frequent
1854 delivery attempts for the huge message than are intended.

1951PH/42 The content-scanning code uses fopen() to create files in which to put

1954 files with open(), and sets the required mode explicitly. Thus, these
1955 files were ending up world-writeable. This was not a big issue, because,
1956 being within the spool directory, they were not world-accessible. I have
1957 created a function called modefopen, which takes an additional mode
1958 argument. It sets umask(777), creates the file, chmods it to the required
1959 mode, then resets the umask. All the relevant calls to fopen() in the

1968PH/45 When the plaintext authenticator is running as a client, the server's
1969 challenges are checked to ensure they are valid base64 strings. By
1970 default, the authentication attempt is cancelled if an invalid string is
1971 received. Setting client_ignore_invalid_base64 true ignores these errors.
1972 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
1973 they are received. Thus, the responses can be made to depend on the
1974 challenges. If an invalid string is ignored, an empty string is placed in
1975 the variable.

1995PH/52 Two bugs concerned with error handling when the smtp transport is
1996 used in LMTP mode:
1997
1998 (i) Exim was not creating retry information for temporary errors given
1999 for individual recipients after the DATA command when the smtp transport
2000 was used in LMTP mode. This meant that they could be retried too
2001 frequently, and not timed out correctly.
2002
2003 (ii) Exim was setting the flag that allows error details to be returned
2004 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2005 recipients that were returned after the DATA command.
2006
2007PH/53 This is related to PH/52, but is more general: for any failing address,
2008 when detailed error information was permitted to be returned to the
2009 sender, but the error was temporary, then after the final timeout, only
2010 "retry timeout exceeded" was returned. Now it returns the full error as
2011 well as "retry timeout exceeded".

2081PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2082 function verify_get_ident() calls ip_connect() to connect a socket, but
2083 if the "connect()" function timed out, ip_connect() used to close the
2084 socket. However, verify_get_ident() also closes the socket later, and in
2085 between Exim writes to the log, which may get opened at this point. When
2086 the socket was closed in ip_connect(), the log could get the same file
2087 descriptor number as the socket. This naturally causes chaos. The fix is
2088 not to close the socket in ip_connect(); the socket should be closed by
2089 the function that creates it. There was only one place in the code where
2090 this was missing, in the iplookup router, which I don't think anybody now
2091 uses, but I've fixed it anyway.

2114
2115 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2116 string.
2117
2118 (3) Reset the variables that are obtained from the first argument of
2119 ${prvscheck and used in the second argument before leaving the code,
2120 because their memory is reclaimed, so using them afterwards may do
2121 silly things.
2122
2123 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2124 one (it's much easier than Tom thought :-).

2147PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2148 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2149 not being looked up in the rDNS to get a host name, Exim was showing the
2150 IP address twice in Received: lines, even though the IP addresses were
2151 identical. For example:
2152
2153 Received: from [1.2.3.4] (helo=[1.2.3.4])
2154
2155 However, if the real host name was known, it was omitting the HELO data
2156 if it matched the actual IP address. This has been tidied up so that it
2157 doesn't show the same IP address twice.

2183PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2185
2186 Auto-submitted: auto-generated
2187
2188 in the messages that it generates (bounce messages and others, such as
2189 warnings). In the case of bounce messages for non-SMTP mesages, there was
2190 also a typo: it was using "Auto_submitted" (underscore instead of
2191 hyphen). Since every message generated by Exim is necessarily in response
2192 to another message, thes have all been changed to:
2193
2194 Auto-Submitted: auto-replied
2195
2196 in accordance with these statements in the RFC:
2197
2198 The auto-replied keyword:
2199
2200 - SHOULD be used on messages sent in direct response to another

2246PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2248 the IP address, check_host() was doing a simple string comparison with
2249 addresses acquired from the DNS when checking that the found name did
2250 have the original IP as one of its addresses. Since any found IPv6
2251 addresses are likely to be in abbreviated form, the comparison could
2252 fail. Luckily, there already exists a function for doing the comparison
2253 by converting both addresses to binary, so now that is used instead of
2254 the text comparison.

2552 with the definition in sysexits.h (which is #included earlier).
2553 Fortunately, Exim does not actually use EX_OK. The code used to try to
2554 preserve the sysexits.h value, by assumimg that macro definitions were
2555 scanned for macro replacements. I have been disabused of this notion,

2561 This seems wrong - if the receiver was accepting one byte at a time it
2562 would take for ever. The timeout is now adjusted when this happens. It
2563 doesn't have to be particularly precise.

2767TK/03 Fix ACL "regex" condition not being available in MIME ACL.
2768
2769PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
2770 to test Sieve filters that use "vacation".
2771
2772PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2773 that changes the way the GnuTLS parameters are stored in the cache file.
2774 The new format can be generated externally. For backward compatibility,
2775 if the data in the cache doesn't make sense, Exim assumes it has read an
2776 old-format file, and it generates new data and writes a new file. This
2777 means that you can't go back to an older release without removing the
2778 file.
2779
2780PH/03 A redirect router that has both "unseen" and "one_time" set does not
2781 work if there are any delivery delays because "one_time" forces the
2782 parent to be marked "delivered", so its unseen clone is never tried
2783 again. For this reason, Exim now forbids the simultaneous setting of
2784 these two options.
2785
2786PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2787 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2788 entry if you want to know the details. The fix, however, neglected to
2789 consider the case when local delivery batching is involved. The test for
2790 "previously delivered" was not happening when checking to see if an
2791 address could be batched with a previous (undelivered) one; under
2792 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2793 address.
1a46a8c5
PH
2794
2795PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2796 in its include files, and this causes problems building Exim.
2797
2798PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2799 header_syntax) but Exim was just ignoring anything given after a slash.
2800 In particular, this caused confusion with an attempt to use "verify =
2801 reverse_host_lookup/defer_ok". An error is now given when options are
2802 supplied for verify items that do not have them. (Maybe reverse_host_
2803 lookup should have a defer_ok option, but that's a different point.)
2804
2805PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2806 defined by RFC 821) to 2048, because there were problems with some AUTH
2807 commands, and RFC 1869 says the size should be increased for extended
2808 SMTP commands that take arguments.
2809
2810PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
2811 Finch).

2846PH/17 The API for radiusclient changed at release 0.4.0. Unfortunately, the

PH
2855PH/19 When an Exim process that is running as root has to create an Exim log
2856 file, it does so in a subprocess that runs as exim:exim so as to get the
2857 ownership right at creation (otherwise, other Exim processes might see
2858 the file with the wrong ownership). There was no test for failure of this
2859 fork() call, which would lead to the process getting stuck as it waited
2860 for a non-existent subprocess. Forks do occasionally fail when resources
2861 run out. I reviewed all the other calls to fork(); they all seem to check
2862 for failure.
2863
f9b9210e
PH
2864PH/20 When checking for unexpected SMTP input at connect time (before writing
2865 the banner), Exim was not dealing correctly with a non-positive return
2866 from the read() function. If the client had disconnected by this time,
2867 the result was a log entry for a synchronization error with an empty
2868 string after "input=" when read() returned zero. If read() returned -1
2869 (an event I could not check), uninitialized data bytes were printed.
2870 There were reports of junk text (parts of files, etc) appearing after
2871 "input=".

2880
c5ddb310
PH
2881PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2882 hadn't been configured. The fix is from Juergen Kreileder, who
2883 understands it better than I do:
2884
2885 "Here's what I see happening with three configured cyrus_sasl
2886 authenticators configured (plain, login, cram-md5):
2887
2888 On startup auth_cyrus_sasl_init() gets called for each of these.
2889 This means three calls to sasl_listmech() without a specified mech_list.
2890 => SASL tests which mechs of all available mechs actually work
2891 => three warnings about OTP not working
2892 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2893
2894 With the patch, sasl_listmech() also gets called three times. But now
2895 SASL's mech_list option is set to the server_mech specified in the the
2896 authenticator. Or in other words, the answer from sasl_listmech()
2897 gets limited to just the mech you're testing for (which is different
2898 for each call.)
2899 => the return list contains just 'plain' or 'login', 'cram-md5' or
2900 nothing depending on the value of ob->server_mech.
2901
2902 I've just tested the patch: Authentication still works fine,
2903 unavailable mechs specified in the exim configuration are still
2904 caught, and the auth.log warnings about OTP are gone."

d7174846
PH
2968PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2969 the grounds that routing the same address twice would always produce the
2970 same answer. This might have been true once, but it is certainly no
2971 longer true now. Routing a child address may depend on the previous
2972 routing that produced that child. Some complicated redirection strategies
2973 went wrong when messages had multiple recipients, and made Exim's
2974 behaviour dependent on the order in which the addresses were given.
2975
2976 I have moved the duplicate checking until after the routing is complete.
2977 Exim scans the addresses that are assigned to local and remote
2978 transports, and removes any duplicates. This means that more work will be
2979 done, as duplicates will always all be routed, but duplicates are
2980 presumably rare, so I don't expect this is of any significance.
2981
2982 For deliveries to pipes, files, and autoreplies, the duplicate checking
2983 still happens during the routing process, since they are not going to be
2984 routed further.

2989 connection it has accepted, or it never writes response data. The exiscan
2990 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
2991 blindly assumes that writes won't block so it may never time out."

3025PH/45 In a pipe transport, although a timeout while waiting for the pipe

3028 successful delivery. Such timeouts include transport filter timeouts. For
3029 consistency with the overall process timeout, these timeouts are now
3030 treated as errors, giving rise to delivery failures by default. However,
3031 there is now a new Boolean option for the pipe transport called
3032 timeout_defer, which, if set TRUE, converts the failures into defers for
3033 both kinds of timeout. A transport filter timeout is now identified in

3043A note about Exim versions 4.44 and 4.50
3044----------------------------------------
3045
3046Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3047changes of various kinds. As a consequence, a big documentation update was
3048needed. This delayed the release for rather longer than seemed good, especially
3049in the light of a couple of (minor) security issues. Therefore, the changes
3050that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3051release. So 4.44 and 4.50 are in effect two different branches that both start
3052from 4.43.
3053
3054I have left the 4.50 change log unchanged; it contains all the changes since
30554.43. The change log for 4.44 is below; many of its items are identical to
3056those for 4.50. This seems to be the most sensible way to preserve the
3057historical information.

3075 5. There are several places where Exim runs a non-Exim command in a
3076 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3077 was being done only for the command run by the queryprogram router. It is
3078 now done for all such subprocesses. The other cases are: ${run, transport
3079 filters, and the commands run by the lmtp and pipe transports.

3083 7. Some older OS have a limit of 256 on the maximum number of file
3084 descriptors. Exim was using setrlimit() to set 1000 as a large value
3085 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3086 systems. I've change it so that if it can't get 1000, it tries for 256.

3137 being passed; this would have caused $sender_host_name to have been used if

3140 "[x.x.x.x]".

3145
314625. Narrowed the window for a race in the daemon that could cause it to ignore

3161 subject address (from a bounce message) matched only if the pattern was an
3162 empty string. Non-empty patterns were not even tested. This was the wrong
3163 because it is perfectly reasonable to use an empty address as part of a
3164 database query. An empty address is now tested by patterns that are
3165 lookups. However, all the other forms of pattern expect the subject to
3166 contain a local part and a domain, and therefore, for them, an empty
3167 address still always fails if the pattern is not itself empty.

316930. Exim went into a mad DNS loop when attempting to do a callout where the
3170 host was specified on an smtp transport, and looking it up yielded more
3171 than one IP address.

PH
317331. Re-factored the code for checking spool and log partition space into a
3174 function that finds that data and another that does the check. The former
3175 is then used to implement four new variables: $spool_space, $log_space,
3176 $spool_inodes, and $log_inodes.

317832. The RFC2047 encoding function was originally intended for short strings
3179 such as real names; it was not keeping to the 75-character limit for
3180 encoded words that the RFC imposes. It now respects the limit, and
3181 generates multiple encoded words if necessary. To be on the safe side, I
3182 have increased the buffer size for the ${rfc2047: expansion operator from
3183 1024 to 2048 bytes.

PH
318533. It is now permitted to omit both strings after an "if" condition; if the
3186 condition is true, the result is "true". As before, when the second string
3187 is omitted, a false condition yields an empty string. This makes it less
3188 cumbersome to write custom ACL and router conditions.

319034. Failure to deliver a bounce message always caused it to be frozen, even if
3191 there was an errors_to setting on the router. The errors_to setting is now
3192 respected.

PH
319435. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3195 canonical form (fully expanded) before being placed in
3196 $sender_host_address.

PH
319836. The table in the code that translates DNS record types into text (T_A to
3199 "A" for instance) was missing entries for NS and CNAME. It is just possible
3200 that this could have caused confusion if both these types were looked up
3201 for the same domain, because the text type is used as part of Exim's
3202 per-process caching. But the chance of anyone hitting this buglet seems
3203 very small.
3204

PH
320537. The dnsdb lookup has been extended in a number of ways.
3206
3207 (1) There is a new type, "zns", which walks up the domain tree until it
3208 finds some nameserver records. It should be used with care.
3209

PH
3210 (2) There is a new type, "mxh", which is like "mx" except that it returns
3211 just the host names, not the priorities.
3212
3213 (3) It is now possible to give a list of domains (or IP addresses) to be

3214 looked up. The behaviour when one of the lookups defers can be
3215 controlled by a keyword.
7bb56e1f 3216
ea3bc19b 3217 (4) It is now possible to specify the separator character for use when
7bb56e1f 3218 multiple records are returned.

PH
322038. The dnslists ACL condition has been extended: it is now possible to supply
3221 a list of IP addresses and/or domains to be looked up in a particular DNS
3222 domain.

PH
322941. Include certificate and key file names in error message when GnuTLS fails

3238
323945. Sometimes the final signoff response after QUIT could fail to get
3240 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3241 < 0 before doing a fflush(). This bug looks as though it goes back to the
3242 introduction of TLS in release 3.20, but "sometimes" must have been rare
3243 because the tests only now provoked it.

PH
324847. exim_tidydb, when checking for the continued existence of a message for
3249 which it has found a message-specific retry record, was not finding
3250 messages that were in split spool directories. Consequently, it was
3251 deleting retry records that should have stayed in existence.

325348. Steve fixed some bugs in eximstats.
3254
325549. The SPA authentication driver was not abandoning authentication and moving
3256 on to the next authenticator when an expansion was forced to fail,
3257 contradicting the general specification for all authenticators. Instead it
3258 was generating a temporary error. It now behaves as specified.

326050. The default ordering of permitted cipher suites for GnuTLS was pessimal
3261 (the order specifies the preference for clients). The order is now AES256,
3262 AES128, 3DES, ARCFOUR128.

PH
326752. Exim crashed if a remote delivery caused a very long error message to be
3268 recorded - for instance if somebody sent an entire SpamAssassin report back
3269 as a large number of 550 error lines. This bug was coincidentally fixed by
3270 increasing the size of one of Exim's internal buffers (big_buffer) that
3271 happened as part of the Exiscan merge. However, to be on the safe side, I
3272 have made the code more robust (and fixed the comments that describe what
3273 is going on).

PH
327553. Now that there can be additional text after "Completed" in log lines (if
3276 the queue_time_overall log selector is set), a one-byte patch to exigrep
3277 was needed to allow it to recognize "Completed" as not the last thing in
3278 the line.

PH
328054. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
3281 patch that reportedly fixes this has been added. I am not expert enough to
3282 create a test for it. This is what the patch creator wrote:
3283
3284 "I found a little strange behaviour of ldap code when working with
3285 Windows 2003 AD Domain, where users was placed in more than one
3286 Organization Units. When I tried to give exim partial DN, the exit code
3287 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
3288 But simultaneously result of request was absolutely normal ldap result,
3289 so I produce this patch..."
3290
3295e65b
PH
3291 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
3292 REFERENCE, so I have modified the code to exclude the patch when that macro
3293 is not defined.

PH
329555. Some experimental protocols are using DNS PTR records for new purposes. The
3296 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
3297 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3298 leaves it alone. Component reversal etc. now happens only for IP addresses.

330959. Two changes related to the smtp_active_hostname option:
3310
3311 (1) $smtp_active_hostname is now available as a variable.
3312 (2) The default for smtp_banner uses $smtp_active_hostname instead
3313 of $primary_hostname.

b975ba52
PH
331560. The host_aton() function is supposed to be passed a string that is known
3316 to be a valid IP address. However, in the case of IPv6 addresses, it was
3317 not checking this. This is a hostage to fortune. Exim now panics and dies
3318 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
3319 from a dnsdb PTR lookup with an IPv6 address that had more than 8
3320 components; fortuitously, this particular loophole had already been fixed
3321 by change 4.50/55 above.
3322
3323 If there are any other similar loopholes, the new check in host_aton()
3324 itself should stop them being exploited. The report I received stated that
3325 data on the command line could provoke the exploit when Exim was running as
3326 exim, but did not say which command line option was involved. All I could
3327 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
3328 running as the user.

PH
333963. The daemon start-up calls getloadavg() while still root for those OS that
3340 need the first call to be done as root, but it missed one case: when
3341 deliver_queue_load_max is set with deliver_drop_privilege. This is
3342 necessary for the benefit of the queue runner, because there is no re-exec
3343 when deliver_drop_privilege is set.

334564. A call to exiwhat cut short delays set up by "delay" modifiers in ACLs.
3346 This has been fixed.
3347
60dc5e56
PH
334865. Caching of lookup data for "hosts =" ACL conditions, when a named host list
3349 was in use, was not putting the data itself into the right store pool;
3350 consequently, it could be overwritten for a subsequent message in the same
3351 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
3352 the caching.)
3353

PH
335466. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
335667. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
3357 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
3358 the function were treating the return as a boolean value, which happened to
3359 work because 0=false and not-0=true, but is not correct code.

PH
336870. If an address verification called from an ACL failed, and did not produce a
3369 user-specific message (i.e. there was only a "system" message), nothing was
3370 put in $acl_verify_message. In this situation, it now puts the system
3371 message there.

PH
337371. Change 4.23/11 added synchronization checking at the start of an SMTP
3374 session; change 4.31/43 added the unwanted input to the log line - except
3375 that it did not do this in the start of session case. It now does.
3376

PH
337772. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
3378 This is wrong and can cause the other end to generate a synchronization
3379 error if it is another Exim or anything else that does the synchronization
3380 check. A QUIT command is no longer sent after a timeout.
