1Change log file for Exim from version 4.21
2-------------------------------------------

8d042305
JH
4Exim version 4.88
5-----------------
9094b84b
JH
6JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
7 supports it and a size is available (ie. the sending peer gave us one).
8d042305 8
03d5892b
JH
9JH/02 The obsolete acl condition "demime" is removed (finally, after ten
10 years of being deprecated). The replacements are the ACLs
11 acl_smtp_mime and acl_not_smtp_mime.
12
4b0fe319
JH
13JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
14 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
15 or even an in-clear connection were permitted. Now, if the host lookup
16 was dnssec and dane was requested then the host is only used if the
17 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
18 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
19 if one fails this test.
20 This means that a poorly-configured remote DNS will make it incommunicado;
21 but it protects against a DNS-interception attack on it.
22
789f8a4f
JH
23JH/04 Bug 1810: make continued-use of an open smtp transport connection
24 non-noisy when a race steals the message being considered.
25
23bb6982 26JH/05 If main configuration option tls_certificate is unset, generate a
f59aaaaa 27 self-signed certificate for inbound TLS connections.
23bb6982 28
0bd1b1ed 29JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 30 in rewrites and routers.
0bd1b1ed 31
20b9a2dc
JH
32JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
33 and logged a warning sing 4.83; now they are a configuration file error.
34
05392bbc
JH
35JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
36 (lacking @domain). Apply the same qualification processing as RCPT.
37
1a6230a3
JH
38JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
39
cfab9d68
JH
40JH/10 Support ${sha256:} applied to a string (as well as the previous
41 certificate).
42
98c82a3d
JH
43JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
44 a cutthrough deliver is pending, as we always want to make a connection.
45 This also avoids re-routing the message when later placing the cutthrough
46 connection after a verify cache hit.
47 Do not update it with the verify result either.
48
49JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
50 when routing results in more than one destination address.
51
ae8386f0
JH
52JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
53 signing (which inhibits the cutthrough capability). Previously only
54 the presence of an option was tested; now an expansion evaluating as
55 empty is permissible (obviously it should depend only on data available
56 when the cutthrough connection is made).
57
0d9fa8c0
JH
58JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
59 the relevant preceding SMTP command did not note the pipelining mode.
60
3581f321
JH
61JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
62 Previously they were not counted.
63
ef3a1a30
JH
64JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
65 as one having no matching records. Previously we deferred the message
66 that needed the lookup.
67
803628d5 68JH/17 Fakereject: previously logged as a norml message arrival "<="; now
27b9e5f4
JH
69 distinguished as "(=".
70
1435d4b2
JH
71JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
72 for missing MX records. Previously it only worked for missing A records.
73
eea0defe
JB
74JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
75
76JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
77 after the data-go-ahead and data-ack. Patch from Jason Betts.

72a201e2
TM
79JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
80 even for a "none" policy. Patch from Tony Meyer.
81
1c788856
JH
82JH/22 Fix continued use of a connection for further deliveries. If a port was
83 specified by a router, it must also match for the delivery to be
84 compatible.
85
e3b1f624
JH
86JH/23 Bug 1874: fix continued use of a connection for further deliveries.
87 When one of the recipients of a message was unsuitable for the connection
88 (has no matching addresses), we lost track of needing to mark it
89 deferred. As a result mail would be lost.
90
a57ce043
JH
91JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
92
f59aaaaa 93JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
94 takes up less space and should be simpler to maintain. Merge the ACL
95 condition decode tables also, with similar effect.
d7bed771 96
d1f9fb42
JH
97JH/26 Fix problem with one_time used on a redirect router which returned the
98 parent address unchanged. A retry would see the parent address marked as
99 delivered, so not attempt the (identical) child. As a result mail would
100 be lost.
101
92b0827a
JH
102JH/27 Fix a possible security hole, wherein a process operating with the Exim
103 UID can gain a root shell. Credit to http://www.halfdog.net/ for
104 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
105 itself :(
106
ddf1b11a
JH
107JH/28 Enable {spool,log} filesystem space and inode checks as default.
108 Main config options check_{log,spool}_{inodes,space} are now
109 100 inodes, 10MB unless set otherwise in the configuration.
110
3cc3f762
JH
111JH/29 Fix the connection_reject log selector to apply to the connect ACL.
112 Previously it only applied to the main-section connection policy
113 options.
114
ae5afa61
JH
115JH/30 Bug 1897: fix callouts connection fallback from TLS to cleartext.
116
317e40ac
PP
117PP/01 Changed default Diffie-Hellman parameters to be Exim-specific, created
118 by me. Added RFC7919 DH primes as an alternative.
119
8b0fb68e
PP
120PP/02 Unbreak build via pkg-config with new hash support when crypto headers
121 are not in the system include path.
122
ad7fc6eb 123JH/31 Fix longstanding bug with aborted TLS server connection handling. Under
f59aaaaa 124 GnuTLS, when a session startup failed (eg because the client disconnected)
ad7fc6eb
JH
125 Exim did stdio operations after fclose. This was exposed by a recent
126 change which nulled out the file handle after the fclose.
ad7fc6eb 127
ee5b1e28
JH
128JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
129 signed directly by the cert-signing cert, rather than an intermediate
130 OCSP-signing cert. This is the model used by LetsEncrypt.
131
5ddc9771
JH
132JH/33 Bug 1914: Ensure socket is nonblocking before draining after SMTP QUIT.
133

0d9b78be
JH
135Exim version 4.87
136-----------------
82d14d6a
JH
137JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
138 and 3.4.4 - once the server is enabled to respond to an OCSP request
139 it does even when not requested, resulting in a stapling non-aware
140 client dropping the TLS connection.
0d9b78be 141
6c6d6e48
TF
142TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
143 support variable-length bit vectors. No functional change.
144
ac881e27
TF
145TF/02 Improve the consistency of logging incoming and outgoing interfaces.
146 The I= interface field on outgoing lines is now after the H= remote
147 host field, same as incoming lines. There is a separate
148 outgoing_interface log selector which allows you to disable the
149 outgoing I= field.
150
c8899c20
JH
151JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
152 If not running log_selector +smtp_connection the mainlog would be held
153 open indefinitely after a "too many connections" event, including to a
154 deleted file after a log rotate. Leave the per net connection logging
155 leaving it open for efficiency as that will be quickly detected by the
156 check on the next write.
157
f1b81d81
HSHR
158HS/01 Bug 1671: Fix post transport crash.
159 Processing the wait-<transport> messages could crash the delivery
160 process if the message IDs didn't exist for some reason. When
161 using 'split_spool_directory=yes' the construction of the spool
162 file name failed already, exposing the same netto behaviour.
163
f38917cc
JH
164JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
165 mime_regex ACL conditions.
166
895fbaf2
JH
167JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
168 to DSN fail messages (bounces): remote IP, remote greeting, remote response
169 to HELO, local diagnostic string.
170
805bb5c3
JH
171JH/05 Downgrade message for a TLS-certificate-based authentication fail from
172 log line to debug. Even when configured with a tls authenticator many
173 client connections are expected to not authenticate in this way, so
174 an authenticate fail is not an error.
175
56c2a7be
HSHR
176HS/02 Add the Exim version string to the process info. This way exiwhat
177 gives some more detail about the running daemon.
178
14b3c5bc
JH
179JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
180 matter for fast-change records such as DNSBLs.
181
6f6dedcc
JH
182JH/07 Bug 1678: Always record an interface option value, if set, as part of a
183 retry record, even if constant. There may be multiple transports with
184 different interface settings and the retry behaviour needs to be kept
185 distinct.
186
0f557e90
JH
187JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
188
189JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
190
ec0eb1a3
JH
191JH/10 Bug 840: fix log_defer_output option of pipe transport
192
41e93589
JH
193JH/11 Bug 830: use same host for all RCPTS of a message, even under
194 hosts_randomize. This matters a lot when combined with mua_wrapper.
195
98b98887 196JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
197 ${quote_pgsql:<string>} operator.
198
98b98887
JH
199JH/13 Bug 1708: avoid misaligned access in cached lookup.
200
858e91c2
JH
201JH/14 Change header file name for freeradius-client. Relevant if compiling
202 with Radius support; from the Gentoo tree and checked under Fedora.
203
204JH/15 Bug 1712: Introduce $prdr_requested flag variable
205
6ff55e50
JH
206JH/16 Bug 1714: Permit an empty string as expansion result for transport
207 option transport_filter, meaning no filtering.
208
3b957582
JB
209JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
210
23f3dc67
JH
211JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
212 defaults to "*" (all hosts). The variable is now available when not built
213 with TLS, default unset, mainly to enable keeping the testuite sane.
214 If a server certificate is not supplied (via tls_certificate) an error is
215 logged, and clients will find TLS connections fail on startup. Presumably
216 they will retry in-clear.
217 Packagers of Exim are strongly encouraged to create a server certificate
218 at installation time.
219
240c288f
JH
220HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
221 with the $config_file variable.
222
5ef5dd52
JB
223JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
224 in transport context, after the attempt, and per-recipient. The latter type
225 is per host attempted. The event data is the error message, and the errno
226 information encodes the lookup type (A vs. MX) used for the (first) host,
227 and the trailing two digits of the smtp 4xx reponse.
228
e161710d
GF
229GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
230 to write to mainlog (or rejectlog, paniclog) in the window between file
231 creation and permissions/ownership being changed. Particularly affects
232 installations where exicyclog is run as root, rather than exim user;
233 result is that the running daemon panics and dies.
234
a159f203
JH
235JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
236
7f06582c
JH
237JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
238 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
239 "pri" and "weight". Note that the previous implicit priority given by the
240 list order is no longer honoured.
241
abe1010c
JH
242JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
243 for DKIM processing.
244
f0989ec0
JH
245JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
246 by defining SUPPORT_SOCKS.
74f150bf 247
cee5f132
JH
248JH/26 Move PROXY support from Experimental to mainline, enabled for a build
249 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
250 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
251 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 252
8c5d388a
JH
253JH/27 Move Internationalisation support from Experimental to mainline, enabled
254 for a build by defining SUPPORT_I18N
255
2d8d625b
JH
256JH/28 Bug 1745: Fix redis lookups to handle (quoted) spaces embedded in parts
257 of the query string, and make ${quote_redis:} do that quoting.
258
0cbf2b82
JH
259JH/29 Move Events support from Experimental to mainline, enabled by default
260 and removable for a build by defining DISABLE_EVENT.
261

262JH/30 Updated DANE implementation code to current from Viktor Dukhovni.
263
ce325893
JH
264JH/31 Fix bug with hosts_connection_nolog and named-lists which were wrongly
265 cached by the daemon.
266
de78e2d5
JH
267JH/32 Move Redis support from Experimental to mainline, enabled for a build
268 by defining LOOKUP_REDIS. The libhiredis library is required.
269
379ba7d0
JH
270JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
271 keys are given for lookup.
272
f444c2c7
JH
273JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
274 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
275 only supported when built with TLS support. The PolarSSL SHA routines
276 are still used when the TLS library is too old for convenient support.
f444c2c7 277
a57b6200
JH
278JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
279 openssl_options), for security. OpenSSL forces this from version 1.1.0
280 server-side so match that on older versions.
281
07c73177 282JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 283 allocation for $value could be released as the expansion processing
07c73177 284 concluded, but leaving the global pointer active for it.
fa01e4f8 285
4f6ae5c3
JH
286JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
287 and to use the domains and local_parts ACL conditions.
288
1bc460a6
JH
289JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
290 incorrectly not doubled on cutthrough transmission, hence seen as a
291 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 292 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
293 via the normal store-and-forward channel. This could result in duplicates
294 received - but deduplicating mailstores were liable to retain only the
295 initial truncated version.
296
ab9152ff 297JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.

JH
304JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.

df3def24 307
13559da6
JH
308JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
309 either intentional arithmetic overflow during PRNG, or testing config-
310 induced overflows.
311
59eaad2b
JH
312JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
313 delivery resulted in actual delivery. Cancel cutthrough before DATA
314 stage.
315
f9334a28
JH
316JH/45 Fix cutthrough, when connection not opened by verify and target hard-
317 rejects a recipient: pass the reject to the originator.
318
dc8091e7
JH
319JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
320 Many were false-positives and ignorable, but it's worth fixing the
321 former class.
322
dfe7d917
JH
323JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
324 for the new environment-manipulation done at startup. Move the routines
325 from being local to tls.c to being global via the os.c file.
326
93cc2d6e
JH
327JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
328 an extract embedded as result-arg for a map, the first arg for extract
329 is unavailable so we cannot tell if this is a numbered or keyed
330 extraction. Accept either.

334Exim version 4.86
335-----------------
336JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
337 expanded.
338
506900af
JH
339JH/02 The smtp transport option "multi_domain" is now expanded.
340
ad07e9ad
JH
341JH/03 The smtp transport now requests PRDR by default, if the server offers
342 it.
343
01a4a5c5 344JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 345 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
346 can be used to disable this per-host. The build option
347 EXPERIMENTAL_CERTNAMES is withdrawn.
348
cb1d7830 349JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 350 default to the word "system" to access the system default CA bundle.
cb1d7830
JH
351 For GnuTLS, only version 3.0.20 or later.
352
610ff438 353JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
354 (but not required) by default. The verification status is now logged by
355 default, for both outbound TLS and client-certificate supplying inbound
356 TLS connections
610ff438 357
f926e272
JH
358JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
359 sites use this now.
360
50dc7409
JH
361JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
362 Status Notification (bounce) messages are now MIME format per RFC 3464.
363 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
364 under the control of the dsn_advertise_hosts option, and routers may
365 have a dsn_lasthop option.
366
0f0c8159
JH
367JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
368 default, modifiable by a malware= option. The list separator for
23763898 369 the options can now be changed in the usual way. Bug 68.
4e71661f 370
1ad6489e
JH
371JH/10 The smtp_receive_timeout main option is now expanded before use.
372
aeaf5db3
JH
373JH/11 The incoming_interface log option now also enables logging of the
374 local interface on delivery outgoing connections.
375
5032d1cf
JH
376JH/12 The cutthrough-routing facility now supports multi-recipient mails,
377 if the interface and destination host and port all match.
378
7e8360e6
JH
379JH/13 Bug 344: The verify = reverse_host_lookup ACL condition now accepts a
380 /defer_ok option.

AL
382JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
383 Patch from Andrew Lewis.
384
fd4d8871 385JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 386 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
387 modifiers per server. Patch originally by <rommer@active.by>.
388
389JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
390 and remote servers. Remote servers can be IPv6 addresses, and
391 specify a port-range.
fd4d8871 392

821TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
822
823 When a queue runner is handling a message, Exim first routes the
824 recipient addresses, during which it prunes them based on the retry
825 hints database. After that it attempts to deliver the message to
826 any remaining recipients. It then updates the hints database using
827 the retry rules.
828
829 So if a recipient address works intermittently, it can get repeatedly
830 deferred at routing time. The retry hints record remains fresh so the
831 address never reaches the final cutoff time.
832
833 This is a fairly common occurrence when a user is bumping up against
834 their storage quota. Exim had some logic in its local delivery code
835 to deal with this. However it did not apply to per-recipient defers
836 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
837
1ddeb334
TF
838 This change adds a proper retry rule check during routing so that the
839 final cutoff time is checked against the message's age. We only do
840 this check if there is an address retry record and there is not a
841 domain retry record; this implies that previous attempts to handle
842 the address had the retry_use_local_parts option turned on. We use
843 this as an approximation for the destination being like a local
844 delivery, as in LMTP.
67bd1ab3
TF
845
846 I suspect this new check makes the old local delivery cutoff check
847 redundant, but I have not verified this so I left the code in place.

882 Server implementation by Todd Lyons, client by JH.
883 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
884 config variable "prdr_enable" controls whether the server
885 advertises the facility. If the client requests PRDR a new
886 acl_data_smtp_prdr ACL is called once for each recipient, after
887 the body content is received and before the acl_smtp_data ACL.
888 The client is controlled by bolth of: a hosts_try_prdr option
889 on the smtp transport, and the server advertisement.
890 Default client logging of deliveries and rejections involving
891 PRDR are flagged with the string "PRDR".

1176 not safe for signals.

1188 are mutually exclusive. The update mode is no longer included in the
1189 database key; it just determines when the database is updated. (This
1190 means that when you upgrde Exim will forget old rate measurements.)
1191
1192 Exim now checks that the per_* options are used with an update mode that
1193 makes sense for the current ACL. For example, when Exim is processing a
1194 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1195 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1196 must specify per_mail/readonly. If you omit the update mode it defaults to
1197 /leaky where that makes sense (as before) or /readonly where required.
1198
1199 The /noupdate option is now undocumented but still supported for
1200 backwards compatibility. It is equivalent to /readonly except that in
1201 ACLs where /readonly is required you may specify /leaky/noupdate or
1202 /strict/noupdate which are treated the same as /readonly.
1203
1204 A useful new feature is the /count= option. This is a generalization
1205 of the per_byte option, so that you can measure the throughput of other
1206 aggregate values. For example, the per_byte option is now equivalent
1207 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1208
1209 The per_rcpt option has been generalized using the /count= mechanism
1210 (though it's more complicated than the per_byte equivalence). When it is
1211 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1212 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1213 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1214 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1215 Note that using per_rcpt with a non-readonly update mode in more than
1216 one ACL will cause the recipients to be double-counted. (The per_mail
1217 and per_byte options don't have this problem.)
1218
1219 The handling of very low rates has changed slightly. If the computed rate
1220 is less than the event's count (usually one) then this event is the first
1221 after a long gap. In this case the rate is set to the same as this event's
1222 count, so that the first message of a spam run is counted properly.
1223
1224 The major new feature is a mechanism for counting the rate of unique
1225 events. The new per_addr option counts the number of different
1226 recipients that someone has sent messages to in the last time period. It
1227 behaves like per_rcpt if all the recipient addresses are different, but
1228 duplicate recipient addresses do not increase the measured rate. Like
1229 the /count= option this is a general mechanism, so the per_addr option
1230 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1231 example, measure the rate that a client uses different sender addresses
1232 with the options per_mail/unique=$sender_address. There are further
1233 details in the main documentation.

1784 were called 'true' and it seems that C99 defines that as a reserved

1786 not include C99-style headers which use bools without triggering

1805PH/01 Another patch from the Sieve maintainer.
1806
6a3bceb1
PH
1807PH/02 When an IPv6 address is converted to a string for single-key lookup
1808 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1809 dots are used instead of colons so that keys in lsearch files need not
1810 contain colons. This was done some time before quoting was made available
1811 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1812 (notated using the quote facility) so as to distinguish them from IPv4
1813 keys. This meant that lookups for IP addresses in host lists did not work
1814 for iplsearch lookups.
1815
1816 This has been fixed by arranging for IPv6 addresses to be expressed with
1817 colons if the lookup type is iplsearch. This is not incompatible, because
1818 previously such lookups could never work.
1819
1820 The situation is now rather anomolous, since one *can* have colons in
1821 ordinary lsearch keys. However, making the change in all cases is
1822 incompatible and would probably break a number of configurations.

MH
1827MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1828 conversion specification without a maximum field width, thereby enabling
1829 a rogue spamd server to cause a buffer overflow. While nobody in their
1830 right mind would setup Exim to query an untrusted spamd server, an
1831 attacker that gains access to a server running spamd could potentially
1832 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1837MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1838 a directory entry by the name of the lookup key. Previously, if a
1839 symlink pointed to a non-existing file or a file in a directory that
1840 Exim lacked permissions to read, a lookup for a key matching that
1841 symlink would fail. Now it is enough that a matching directory entry
1842 exists, symlink or not. (Bugzilla 503.)

2025PH/29 SMTP synchronization checks are implemented when a command is read -
2026 there is a check that no more input is waiting when there shouldn't be

2028 some time before the response is written. In this time, more input might
2029 arrive, invalidly. So now there are extra checks after an ACL has run for
2030 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2031 pipelining has not been advertised.

PH
2105 the response to the final '.' that terminates a message, but only in the
2106 case where the client has not sent further data following the '.'
2107 (unfortunately, this is allowed). However, in many cases there won't be
2108 any further data because there won't be any more messages to send. A call
2109 to select() can be used: if it shows that the input is "ready", there is
2110 either input waiting, or the socket has been closed. An attempt to read
2111 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2112 would have sent an OK response which the client would never have see.

2123PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2124 fixed by 4.65/MH/01 (is this a record?) are fixed:
2125
2126 (i) An empty string was always treated as zero by the numeric comparison
2127 operators. This behaviour has been restored.
2128
2129 (ii) It is documented that the numeric comparison operators always treat
2130 their arguments as decimal numbers. This was broken in that numbers
2131 starting with 0 were being interpreted as octal.
2132
2133 While fixing these problems I realized that there was another issue that
2134 hadn't been noticed. Values of message_size_limit (both the global option
2135 and the transport option) were treated as octal if they started with 0.
2136 The documentation was vague. These values are now always treated as
2137 decimal, and I will make that clear in the documentation.

2151PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

2153 is held in a short int, deliveries were likely to be lost. As such a
2154 large number of recipients for a single message is ridiculous
2155 (performance will be very, very poor), I have chosen to impose a limit
2156 rather than extend the field.

PH
2181PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2182 callout verification, Exim cached a "reject" for the entire domain. This
2183 is correct for most verifications, but it is not correct for a recipient
2184 verification with use_sender or use_postmaster set, because in that case
2185 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2186 case of MAIL FROM:<> rejection from other early rejections (e.g.
2187 rejection of HELO). When verifying a recipient using a non-null MAIL
2188 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2189 Whatever the result of the callout, the value of the domain cache is
2190 left unchanged (for any other kind of callout, getting as far as trying
2191 RCPT means that the domain itself is ok).

2225PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2227 probably the interface on which it is arriving) and not to the outgoing
2228 callout (which could be using a different interface). This has been
2229 changed to use the value of the helo_data option from the smtp transport
2230 instead - this is what is used when a message is actually being sent. If
2231 there is no remote transport (possible with a router that sets up host
2232 addresses), $smtp_active_hostname is used.

7befa435 2235 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2236 (a) The code assumed that strncpy() returns a negative number on buffer
2237 overflow, which isn't the case. Replaced with Exim's string_format()
2238 function.
2239 (b) There were several signed/unsigned issues. I just did the minimum
2240 hacking in of casts. There is scope for a larger refactoring.
2241 (c) The code used strcasecmp() which is not a standard C function.
2242 Replaced with Exim's strcmpic() function.
2243 (d) The code set only $1; it now sets $auth1 as well.
2244 (e) A simple test gave the error "authentication client didn't specify
2245 service in request". It would seem that Dovecot has changed its
2246 interface. Fortunately there's a specification; I followed it and
2247 changed what the client sends and it appears to be working now.

2253 address A is aliased to B and C, where B exists and C does not. Without
2254 -v the output is "A verified" because verification stops after a
2255 successful redirection if more than one address is generated. However,
2256 with -v the child addresses are also verified. Exim was outputting "A
2257 failed to verify" and then showing the successful verification for C,
2258 with its parentage. It now outputs "B failed to verify", showing B's
2259 parentage before showing the successful verification of C.

2264
322050c2
PH
2265PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2266 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2267 they consult the DNS. I had assumed they would set it the way they
2268 wanted; and indeed my experiments on Linux seem to show that in some
2269 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2270 To be on the safe side, however, I have now made the interface to
2271 host_find_byname() similar to host_find_bydns(), with an argument
2272 containing the DNS resolver options. The host_find_byname() function now
2273 sets these options at its start, just as host_find_bydns() does. The smtp
2274 transport options dns_qualify_single and dns_search_parents are passed to
2275 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2276 of host_find_byname() use the default settings of RES_DEFNAMES
2277 (qualify_single) but not RES_DNSRCH (search_parents).

2280 spool_read_header() do less string testing, by means of a preliminary
2281 switch on the second character of optional "-foo" lines. (This is
2282 overdue, caused by the large number of possibilities that now exist.
2283 Originally there were few.) While I was there, I also converted the
2284 str(n)cmp tests so they don't re-test the leading "-" and the first
2285 character, in the hope this might squeeze out yet more improvement.

2287PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2288 flag allowing group syntax was set by the header_syntax check but not
2289 turned off, possible causing trouble later; (2) The flag was not being
2290 set at all for the header_verify test, causing "group"-style headers to
2291 be rejected. I have now set it in this case, and also caused header_
2292 verify to ignore an empty address taken from a group. While doing this, I
2293 came across some other cases where the code for allowing group syntax
2294 while scanning a header line wasn't quite right (mostly, not resetting
2295 the flag correctly in the right place). These bugs could have caused
2296 trouble for malformed header lines. I hope it is now all correct.

2298PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

PH
2304PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

2307 only MTA that supported it -- and would never use it because real RSA is
2308 always available. This code has been removed, because it had the bad
2309 effect of slowing Exim down by computing (never used) parameters for the
2310 RSA_EXPORT functionality.

2350PH/30 Exim was sometimes attempting to deliver messages that had suffered
2351 address errors (4xx response to RCPT) over the same connection as other
2352 messages routed to the same hosts. Such deliveries are always "forced",
2353 so retry times are not inspected. This resulted in far too many retries
2354 for the affected addresses. The effect occurred only when there were more
2355 hosts than the hosts_max_try setting in the smtp transport when it had
2356 the 4xx errors. Those hosts that it had tried were not added to the list
2357 of hosts for which the message was waiting, so if all were tried, there
2358 was no problem. Two fixes have been applied:
2359
2360 (i) If there are any address or message errors in an SMTP delivery, none
2361 of the hosts (tried or untried) are now added to the list of hosts
2362 for which the message is waiting, so the message should not be a
2363 candidate for sending over the same connection that was used for a
2364 successful delivery of some other message. This seems entirely
2365 reasonable: after all the message is NOT "waiting for some host".
2366 This is so "obvious" that I'm not sure why it wasn't done
2367 previously. Hope I haven't missed anything, but it can't do any
2368 harm, as the worst effect is to miss an optimization.
2369
2370 (ii) If, despite (i), such a delivery is accidentally attempted, the
2371 routing retry time is respected, so at least it doesn't keep
2372 hammering the server.

2387PH/35 The error "getsockname() failed: connection reset by peer" was being
2388 written to the panic log as well as the main log, but it isn't really

2390 removed the panic log writing for the ECONNRESET error when getsockname()
2391 fails.
2392
48c7f9e2
PH
2393PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2394 runs only) independently of the message's sender address. This meant
2395 that, if the 4xx error was in fact related to the sender, a different
2396 message to the same recipient with a different sender could confuse
2397 things. In particualar, this can happen when sending to a greylisting
2398 server, but other circumstances could also provoke similar problems.
2399 I have changed the default so that the retry time for these errors is now
2400 based a combination of the sender and recipient addresses. This change
2401 can be overridden by setting address_retry_include_sender=false in the
2402 smtp transport.

2675 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2676 554 error is used if errno is still zero or contains ENOENT (which occurs

2718 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2719 that it would not match correctly against @[] and not recognize the IPv6
2720 addresses as local.

2763 autoreply, Exim could try to deliver to a non-existent relative file

2787 in a subprocess such as that created by queryprogram now generate
2788 suitable debugging ouput when -d is set.

2797PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2798 additional section of a DNS packet that returns MX or SRV records.
2799 Instead, it always explicitly searches for A/AAAA records. This avoids
2800 major problems that occur when a DNS server includes only records of one
2801 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2802 fixed another bug: if SRV records were looked up and the corresponding
2803 address records were *not* found in the additional section, the port
2804 values from the SRV records were lost.

PH
2814PH/19 When calculating a retry time, Exim used to measure the "time since
2815 failure" by looking at the "first failed" field in the retry record. Now
2816 it does not use this if it is later than than the arrival time of the
2817 message. Instead it uses the arrival time. This makes for better
2818 behaviour in cases where some deliveries succeed, thus re-setting the
2819 "first failed" field. An example is a quota failure for a huge message
2820 when small messages continue to be delivered. Without this change, the
2821 "time since failure" will always be short, possible causing more frequent
2822 delivery attempts for the huge message than are intended.

PH
2919PH/42 The content-scanning code uses fopen() to create files in which to put
2920 message data. Previously it was not paying any attention to the mode of
2921 the files. Exim runs with umask(0) because the rest of the code creates
2922 files with open(), and sets the required mode explicitly. Thus, these
2923 files were ending up world-writeable. This was not a big issue, because,
2924 being within the spool directory, they were not world-accessible. I have
2925 created a function called modefopen, which takes an additional mode
2926 argument. It sets umask(777), creates the file, chmods it to the required
2927 mode, then resets the umask. All the relevant calls to fopen() in the

2965
2966 (i) Exim was not creating retry information for temporary errors given
2967 for individual recipients after the DATA command when the smtp transport
2968 was used in LMTP mode. This meant that they could be retried too
2969 frequently, and not timed out correctly.
2970
2971 (ii) Exim was setting the flag that allows error details to be returned
2972 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2973 recipients that were returned after the DATA command.
2974
2975PH/53 This is related to PH/52, but is more general: for any failing address,
2976 when detailed error information was permitted to be returned to the
2977 sender, but the error was temporary, then after the final timeout, only
2978 "retry timeout exceeded" was returned. Now it returns the full error as

3050 function verify_get_ident() calls ip_connect() to connect a socket, but
3051 if the "connect()" function timed out, ip_connect() used to close the
3052 socket. However, verify_get_ident() also closes the socket later, and in
3053 between Exim writes to the log, which may get opened at this point. When
3054 the socket was closed in ip_connect(), the log could get the same file
3055 descriptor number as the socket. This naturally causes chaos. The fix is
3056 not to close the socket in ip_connect(); the socket should be closed by
3057 the function that creates it. There was only one place in the code where
3058 this was missing, in the iplookup router, which I don't think anybody now
3059 uses, but I've fixed it anyway.

3109 This has been changed so that it extracts the operative address. There
3110 may be more than one such address. If so, they are comma-separated, like
3111 this:

3115PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3116 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3117 not being looked up in the rDNS to get a host name, Exim was showing the
3118 IP address twice in Received: lines, even though the IP addresses were
3119 identical. For example:
3120
3121 Received: from [1.2.3.4] (helo=[1.2.3.4])
3122
3123 However, if the real host name was known, it was omitting the HELO data
3124 if it matched the actual IP address. This has been tidied up so that it
3125 doesn't show the same IP address twice.

3127PH/07 When both +timestamp and +memory debugging was on, the value given by
3128 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3129 called by the debug printing, thereby overwriting the timestamp buffer.
3130 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3151PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3152 Electronic Mail") by including:
3153
3154 Auto-submitted: auto-generated
3155
3156 in the messages that it generates (bounce messages and others, such as
3157 warnings). In the case of bounce messages for non-SMTP mesages, there was
3158 also a typo: it was using "Auto_submitted" (underscore instead of
3159 hyphen). Since every message generated by Exim is necessarily in response
3160 to another message, thes have all been changed to:
3161
3162 Auto-Submitted: auto-replied
3163
3164 in accordance with these statements in the RFC:
3165
3166 The auto-replied keyword:
3167
3168 - SHOULD be used on messages sent in direct response to another
3169 message by an automatic process,
3170
3171 - MUST NOT be used on manually-generated messages,
3172
3173 - MAY be used on Delivery Status Notifications (DSNs) and Message
3174 Disposition Notifications (MDNs),
3175
3176 - MUST NOT be used on messages generated by automatic or periodic
3177 processes, except for messages which are automatic responses to
3178 other messages.

3199PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3200 extension "envelope-auth". The code is finished and in agreement with
3201 other implementations, but there is no documentation so far and in fact,
3202 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3203 not changing the active code.
3204
3205 Print executed "if" and "elsif" statements when debugging is used. This
3206 helps a great deal to understand what a filter does.
3207

3209 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3214PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3215 canonical form (as documented). However, after a host name lookup from
3216 the IP address, check_host() was doing a simple string comparison with
3217 addresses acquired from the DNS when checking that the found name did
3218 have the original IP as one of its addresses. Since any found IPv6
3219 addresses are likely to be in abbreviated form, the comparison could
3220 fail. Luckily, there already exists a function for doing the comparison
3221 by converting both addresses to binary, so now that is used instead of
3222 the text comparison.
3223

PH
3224PH/20 There was another similar case to PH/19, when a complete host name was
3225 given in a host list; looking up its IP address could give an abbreviated
3226 form, whereas the current host's name might or might not be abbreviated.
3227 The same fix has been applied.
