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.
860cdda2 78
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.

JH
129Exim version 4.87
130-----------------
82d14d6a
JH
131JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
132 and 3.4.4 - once the server is enabled to respond to an OCSP request
133 it does even when not requested, resulting in a stapling non-aware
134 client dropping the TLS connection.
0d9b78be 135
6c6d6e48
TF
136TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
137 support variable-length bit vectors. No functional change.
138
ac881e27
TF
139TF/02 Improve the consistency of logging incoming and outgoing interfaces.
140 The I= interface field on outgoing lines is now after the H= remote
141 host field, same as incoming lines. There is a separate
142 outgoing_interface log selector which allows you to disable the
143 outgoing I= field.
144
c8899c20
JH
145JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
146 If not running log_selector +smtp_connection the mainlog would be held
147 open indefinitely after a "too many connections" event, including to a
148 deleted file after a log rotate. Leave the per net connection logging
149 leaving it open for efficiency as that will be quickly detected by the
150 check on the next write.
151
f1b81d81
HSHR
152HS/01 Bug 1671: Fix post transport crash.
153 Processing the wait-<transport> messages could crash the delivery
154 process if the message IDs didn't exist for some reason. When
155 using 'split_spool_directory=yes' the construction of the spool
156 file name failed already, exposing the same netto behaviour.
157
f38917cc
JH
158JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
159 mime_regex ACL conditions.
160
895fbaf2
JH
161JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
162 to DSN fail messages (bounces): remote IP, remote greeting, remote response
163 to HELO, local diagnostic string.
164
805bb5c3
JH
165JH/05 Downgrade message for a TLS-certificate-based authentication fail from
166 log line to debug. Even when configured with a tls authenticator many
167 client connections are expected to not authenticate in this way, so
168 an authenticate fail is not an error.
169
56c2a7be
HSHR
170HS/02 Add the Exim version string to the process info. This way exiwhat
171 gives some more detail about the running daemon.
172
14b3c5bc
JH
173JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
174 matter for fast-change records such as DNSBLs.
175
6f6dedcc
JH
176JH/07 Bug 1678: Always record an interface option value, if set, as part of a
177 retry record, even if constant. There may be multiple transports with
178 different interface settings and the retry behaviour needs to be kept
179 distinct.
180
0f557e90
JH
181JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
182
183JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
184
ec0eb1a3
JH
185JH/10 Bug 840: fix log_defer_output option of pipe transport
186
41e93589
JH
187JH/11 Bug 830: use same host for all RCPTS of a message, even under
188 hosts_randomize. This matters a lot when combined with mua_wrapper.
189
98b98887 190JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
191 ${quote_pgsql:<string>} operator.
192
98b98887
JH
193JH/13 Bug 1708: avoid misaligned access in cached lookup.
194
858e91c2
JH
195JH/14 Change header file name for freeradius-client. Relevant if compiling
196 with Radius support; from the Gentoo tree and checked under Fedora.
197
198JH/15 Bug 1712: Introduce $prdr_requested flag variable
199
6ff55e50
JH
200JH/16 Bug 1714: Permit an empty string as expansion result for transport
201 option transport_filter, meaning no filtering.
202
3b957582
JB
203JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
204
23f3dc67
JH
205JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
206 defaults to "*" (all hosts). The variable is now available when not built
207 with TLS, default unset, mainly to enable keeping the testuite sane.
208 If a server certificate is not supplied (via tls_certificate) an error is
209 logged, and clients will find TLS connections fail on startup. Presumably
210 they will retry in-clear.
211 Packagers of Exim are strongly encouraged to create a server certificate
212 at installation time.
213
240c288f
JH
214HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
215 with the $config_file variable.
216
5ef5dd52
JB
217JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
218 in transport context, after the attempt, and per-recipient. The latter type
219 is per host attempted. The event data is the error message, and the errno
220 information encodes the lookup type (A vs. MX) used for the (first) host,
221 and the trailing two digits of the smtp 4xx reponse.
222
e161710d
GF
223GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
224 to write to mainlog (or rejectlog, paniclog) in the window between file
225 creation and permissions/ownership being changed. Particularly affects
226 installations where exicyclog is run as root, rather than exim user;
227 result is that the running daemon panics and dies.
228
a159f203
JH
229JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
230
7f06582c
JH
231JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
232 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
233 "pri" and "weight". Note that the previous implicit priority given by the
234 list order is no longer honoured.
235
abe1010c
JH
236JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
237 for DKIM processing.
238
f0989ec0
JH
239JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
240 by defining SUPPORT_SOCKS.
74f150bf 241
cee5f132
JH
242JH/26 Move PROXY support from Experimental to mainline, enabled for a build
243 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
244 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
245 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 246
8c5d388a
JH
247JH/27 Move Internationalisation support from Experimental to mainline, enabled
248 for a build by defining SUPPORT_I18N
249
2d8d625b
JH
250JH/28 Bug 1745: Fix redis lookups to handle (quoted) spaces embedded in parts
251 of the query string, and make ${quote_redis:} do that quoting.
252
0cbf2b82
JH
253JH/29 Move Events support from Experimental to mainline, enabled by default
254 and removable for a build by defining DISABLE_EVENT.
255
f2f2c91b
JH
256JH/30 Updated DANE implementation code to current from Viktor Dukhovni.
257
ce325893
JH
258JH/31 Fix bug with hosts_connection_nolog and named-lists which were wrongly
259 cached by the daemon.
260
de78e2d5
JH
261JH/32 Move Redis support from Experimental to mainline, enabled for a build
262 by defining LOOKUP_REDIS. The libhiredis library is required.
263
379ba7d0
JH
264JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
265 keys are given for lookup.
266
f444c2c7
JH
267JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
268 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
269 only supported when built with TLS support. The PolarSSL SHA routines
270 are still used when the TLS library is too old for convenient support.
f444c2c7 271
a57b6200
JH
272JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
273 openssl_options), for security. OpenSSL forces this from version 1.1.0
274 server-side so match that on older versions.
275
07c73177 276JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 277 allocation for $value could be released as the expansion processing
07c73177 278 concluded, but leaving the global pointer active for it.
fa01e4f8 279
4f6ae5c3
JH
280JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
281 and to use the domains and local_parts ACL conditions.
282
1bc460a6
JH
283JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
284 incorrectly not doubled on cutthrough transmission, hence seen as a
285 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 286 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
287 via the normal store-and-forward channel. This could result in duplicates
288 received - but deduplicating mailstores were liable to retain only the
289 initial truncated version.
290
ab9152ff 291JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.
df3def24 292
67e87fcf
JH
293JH/40 Fix crash in queryprogram router when compiled with EXPERIMENTAL_SRS.
294
ab9152ff
JH
295JH/41 Bug 1792: Fix selection of headers to sign for DKIM: bottom-up. While
296 we're in there, support oversigning also; bug 1309.
297
af483912
JH
298JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.
299
bc3c7bb7 300HS/04 Add support for keep_environment and add_environment options.
df3def24 301
13559da6
JH
302JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
303 either intentional arithmetic overflow during PRNG, or testing config-
304 induced overflows.
305
59eaad2b
JH
306JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
307 delivery resulted in actual delivery. Cancel cutthrough before DATA
308 stage.
309
f9334a28
JH
310JH/45 Fix cutthrough, when connection not opened by verify and target hard-
311 rejects a recipient: pass the reject to the originator.
312
dc8091e7
JH
313JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
314 Many were false-positives and ignorable, but it's worth fixing the
315 former class.
316
dfe7d917
JH
317JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
318 for the new environment-manipulation done at startup. Move the routines
319 from being local to tls.c to being global via the os.c file.
320
93cc2d6e
JH
321JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
322 an extract embedded as result-arg for a map, the first arg for extract
323 is unavailable so we cannot tell if this is a numbered or keyed
324 extraction. Accept either.

328Exim version 4.86
329-----------------
330JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
331 expanded.
332
506900af
JH
333JH/02 The smtp transport option "multi_domain" is now expanded.
334
ad07e9ad
JH
335JH/03 The smtp transport now requests PRDR by default, if the server offers
336 it.
337
01a4a5c5 338JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 339 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
340 can be used to disable this per-host. The build option
341 EXPERIMENTAL_CERTNAMES is withdrawn.
342
cb1d7830 343JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 344 default to the word "system" to access the system default CA bundle.
cb1d7830
JH
345 For GnuTLS, only version 3.0.20 or later.
346
610ff438 347JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
348 (but not required) by default. The verification status is now logged by
349 default, for both outbound TLS and client-certificate supplying inbound
350 TLS connections
610ff438 351
f926e272
JH
352JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
353 sites use this now.
354
50dc7409
JH
355JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
356 Status Notification (bounce) messages are now MIME format per RFC 3464.
357 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
358 under the control of the dsn_advertise_hosts option, and routers may
359 have a dsn_lasthop option.
360
0f0c8159
JH
361JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
362 default, modifiable by a malware= option. The list separator for
23763898 363 the options can now be changed in the usual way. Bug 68.
4e71661f 364
1ad6489e
JH
365JH/10 The smtp_receive_timeout main option is now expanded before use.
366
aeaf5db3
JH
367JH/11 The incoming_interface log option now also enables logging of the
368 local interface on delivery outgoing connections.
369
5032d1cf
JH
370JH/12 The cutthrough-routing facility now supports multi-recipient mails,
371 if the interface and destination host and port all match.
372
7e8360e6
JH
373JH/13 Bug 344: The verify = reverse_host_lookup ACL condition now accepts a
374 /defer_ok option.
375
c5f280e2
AL
376JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
377 Patch from Andrew Lewis.
378
fd4d8871 379JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 380 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
381 modifiers per server. Patch originally by <rommer@active.by>.
382
383JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
384 and remote servers. Remote servers can be IPv6 addresses, and
385 specify a port-range.
fd4d8871 386
23763898

387JH/17 Bug 68: The spamd_address main option now supports an optional
388 timeout value per server.
389
2ad78978
JH
390JH/18 Bug 1581: Router and transport options headers_add/remove can
391 now have the list separator specified.

456 script to read through the entire script once to detect and set these
457 variables, reset to the beginning of the script, and then run through

815TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
816
817 When a queue runner is handling a message, Exim first routes the
818 recipient addresses, during which it prunes them based on the retry
819 hints database. After that it attempts to deliver the message to
820 any remaining recipients. It then updates the hints database using
821 the retry rules.
822
823 So if a recipient address works intermittently, it can get repeatedly
824 deferred at routing time. The retry hints record remains fresh so the
825 address never reaches the final cutoff time.
826
827 This is a fairly common occurrence when a user is bumping up against
828 their storage quota. Exim had some logic in its local delivery code
829 to deal with this. However it did not apply to per-recipient defers
830 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
831
1ddeb334
TF
832 This change adds a proper retry rule check during routing so that the
833 final cutoff time is checked against the message's age. We only do
834 this check if there is an address retry record and there is not a
835 domain retry record; this implies that previous attempts to handle
836 the address had the retry_use_local_parts option turned on. We use
837 this as an approximation for the destination being like a local
838 delivery, as in LMTP.
67bd1ab3
TF
839
840 I suspect this new check makes the old local delivery cutoff check
841 redundant, but I have not verified this so I left the code in place.

876 Server implementation by Todd Lyons, client by JH.
877 Only enabled when compiled with EXPERIMENTAL_PRDR. A new

879 advertises the facility. If the client requests PRDR a new
880 acl_data_smtp_prdr ACL is called once for each recipient, after
881 the body content is received and before the acl_smtp_data ACL.
882 The client is controlled by bolth of: a hosts_try_prdr option
883 on the smtp transport, and the server advertisement.
884 Default client logging of deliveries and rejections involving
885 PRDR are flagged with the string "PRDR".

1166
1167 The SIGUSR1 handler appends the current process status to the process
1168 log which is later printed by exiwhat. It used to use the general
1169 purpose logging code to do this, but several functions it calls are
1170 not safe for signals.
1171
1172 The new output code in the SIGUSR1 handler is specific to the process
1173 log, and simple enough that it's easy to inspect for signal safety.

1186 Exim now checks that the per_* options are used with an update mode that
1187 makes sense for the current ACL. For example, when Exim is processing a
1188 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1189 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1190 must specify per_mail/readonly. If you omit the update mode it defaults to
1191 /leaky where that makes sense (as before) or /readonly where required.
1192
1193 The /noupdate option is now undocumented but still supported for
1194 backwards compatibility. It is equivalent to /readonly except that in
1195 ACLs where /readonly is required you may specify /leaky/noupdate or
1196 /strict/noupdate which are treated the same as /readonly.
1197
1198 A useful new feature is the /count= option. This is a generalization
1199 of the per_byte option, so that you can measure the throughput of other
1200 aggregate values. For example, the per_byte option is now equivalent
1201 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1202
1203 The per_rcpt option has been generalized using the /count= mechanism
1204 (though it's more complicated than the per_byte equivalence). When it is
1205 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1206 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1207 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1208 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1209 Note that using per_rcpt with a non-readonly update mode in more than
1210 one ACL will cause the recipients to be double-counted. (The per_mail
1211 and per_byte options don't have this problem.)
1212
1213 The handling of very low rates has changed slightly. If the computed rate
1214 is less than the event's count (usually one) then this event is the first
1215 after a long gap. In this case the rate is set to the same as this event's
1216 count, so that the first message of a spam run is counted properly.
1217
1218 The major new feature is a mechanism for counting the rate of unique
1219 events. The new per_addr option counts the number of different
1220 recipients that someone has sent messages to in the last time period. It
1221 behaves like per_rcpt if all the recipient addresses are different, but
1222 duplicate recipient addresses do not increase the measured rate. Like
1223 the /count= option this is a general mechanism, so the per_addr option
1224 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1225 example, measure the rate that a client uses different sender addresses
1226 with the options per_mail/unique=$sender_address. There are further
1227 details in the main documentation.

1799PH/01 Another patch from the Sieve maintainer.
1800
6a3bceb1
PH
1801PH/02 When an IPv6 address is converted to a string for single-key lookup
1802 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1803 dots are used instead of colons so that keys in lsearch files need not
1804 contain colons. This was done some time before quoting was made available
1805 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1806 (notated using the quote facility) so as to distinguish them from IPv4
1807 keys. This meant that lookups for IP addresses in host lists did not work
1808 for iplsearch lookups.
1809
1810 This has been fixed by arranging for IPv6 addresses to be expressed with
1811 colons if the lookup type is iplsearch. This is not incompatible, because
1812 previously such lookups could never work.
1813
1814 The situation is now rather anomolous, since one *can* have colons in
1815 ordinary lsearch keys. However, making the change in all cases is
1816 incompatible and would probably break a number of configurations.

1821MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1822 conversion specification without a maximum field width, thereby enabling
1823 a rogue spamd server to cause a buffer overflow. While nobody in their
1824 right mind would setup Exim to query an untrusted spamd server, an
1825 attacker that gains access to a server running spamd could potentially
1826 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1831MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1832 a directory entry by the name of the lookup key. Previously, if a
1833 symlink pointed to a non-existing file or a file in a directory that
1834 Exim lacked permissions to read, a lookup for a key matching that
1835 symlink would fail. Now it is enough that a matching directory entry
1836 exists, symlink or not. (Bugzilla 503.)

2019PH/29 SMTP synchronization checks are implemented when a command is read -
2020 there is a check that no more input is waiting when there shouldn't be

2022 some time before the response is written. In this time, more input might
2023 arrive, invalidly. So now there are extra checks after an ACL has run for
2024 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2025 pipelining has not been advertised.

PH
2099 the response to the final '.' that terminates a message, but only in the
2100 case where the client has not sent further data following the '.'
2101 (unfortunately, this is allowed). However, in many cases there won't be
2102 any further data because there won't be any more messages to send. A call
2103 to select() can be used: if it shows that the input is "ready", there is
2104 either input waiting, or the socket has been closed. An attempt to read
2105 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2106 would have sent an OK response which the client would never have see.

2117PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2118 fixed by 4.65/MH/01 (is this a record?) are fixed:
2119
2120 (i) An empty string was always treated as zero by the numeric comparison
2121 operators. This behaviour has been restored.
2122
2123 (ii) It is documented that the numeric comparison operators always treat
2124 their arguments as decimal numbers. This was broken in that numbers
2125 starting with 0 were being interpreted as octal.
2126
2127 While fixing these problems I realized that there was another issue that
2128 hadn't been noticed. Values of message_size_limit (both the global option
2129 and the transport option) were treated as octal if they started with 0.
2130 The documentation was vague. These values are now always treated as
2131 decimal, and I will make that clear in the documentation.

2145PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

2147 is held in a short int, deliveries were likely to be lost. As such a
2148 large number of recipients for a single message is ridiculous
2149 (performance will be very, very poor), I have chosen to impose a limit
2150 rather than extend the field.

2156TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2157 leftover -K file (the existence of which was triggered by #402).

2166TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
2175PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2176 callout verification, Exim cached a "reject" for the entire domain. This
2177 is correct for most verifications, but it is not correct for a recipient
2178 verification with use_sender or use_postmaster set, because in that case
2179 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2180 case of MAIL FROM:<> rejection from other early rejections (e.g.
2181 rejection of HELO). When verifying a recipient using a non-null MAIL
2182 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2183 Whatever the result of the callout, the value of the domain cache is
2184 left unchanged (for any other kind of callout, getting as far as trying
2185 RCPT means that the domain itself is ok).

2219PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2221 probably the interface on which it is arriving) and not to the outgoing
2222 callout (which could be using a different interface). This has been
2223 changed to use the value of the helo_data option from the smtp transport
2224 instead - this is what is used when a message is actually being sent. If
2225 there is no remote transport (possible with a router that sets up host
2226 addresses), $smtp_active_hostname is used.

7befa435 2229 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2230 (a) The code assumed that strncpy() returns a negative number on buffer
2231 overflow, which isn't the case. Replaced with Exim's string_format()
2232 function.
2233 (b) There were several signed/unsigned issues. I just did the minimum
2234 hacking in of casts. There is scope for a larger refactoring.
2235 (c) The code used strcasecmp() which is not a standard C function.
2236 Replaced with Exim's strcmpic() function.
2237 (d) The code set only $1; it now sets $auth1 as well.
2238 (e) A simple test gave the error "authentication client didn't specify
2239 service in request". It would seem that Dovecot has changed its
2240 interface. Fortunately there's a specification; I followed it and
2241 changed what the client sends and it appears to be working now.

2247 address A is aliased to B and C, where B exists and C does not. Without
2248 -v the output is "A verified" because verification stops after a
2249 successful redirection if more than one address is generated. However,
2250 with -v the child addresses are also verified. Exim was outputting "A
2251 failed to verify" and then showing the successful verification for C,
2252 with its parentage. It now outputs "B failed to verify", showing B's
2253 parentage before showing the successful verification of C.

2256 look up a TXT record in a specific list after matching in a combined

2258
322050c2
PH
2259PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2260 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2261 they consult the DNS. I had assumed they would set it the way they
2262 wanted; and indeed my experiments on Linux seem to show that in some
2263 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2264 To be on the safe side, however, I have now made the interface to
2265 host_find_byname() similar to host_find_bydns(), with an argument
2266 containing the DNS resolver options. The host_find_byname() function now
2267 sets these options at its start, just as host_find_bydns() does. The smtp
2268 transport options dns_qualify_single and dns_search_parents are passed to
2269 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2270 of host_find_byname() use the default settings of RES_DEFNAMES
2271 (qualify_single) but not RES_DNSRCH (search_parents).

2273PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2274 spool_read_header() do less string testing, by means of a preliminary
2275 switch on the second character of optional "-foo" lines. (This is
2276 overdue, caused by the large number of possibilities that now exist.
2277 Originally there were few.) While I was there, I also converted the
2278 str(n)cmp tests so they don't re-test the leading "-" and the first
2279 character, in the hope this might squeeze out yet more improvement.

2281PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2282 flag allowing group syntax was set by the header_syntax check but not
2283 turned off, possible causing trouble later; (2) The flag was not being
2284 set at all for the header_verify test, causing "group"-style headers to
2285 be rejected. I have now set it in this case, and also caused header_
2286 verify to ignore an empty address taken from a group. While doing this, I
2287 came across some other cases where the code for allowing group syntax
2288 while scanning a header line wasn't quite right (mostly, not resetting
2289 the flag correctly in the right place). These bugs could have caused
2290 trouble for malformed header lines. I hope it is now all correct.

PH
2292PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2295 but it didn't always do it. This confused somebody who was copying the
2296 code for some other use. I have removed all the tests.

PH
2298PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2299 feature that was used to support insecure browsers during the U.S. crypto
2300 embargo. It requires special client support, and Exim is probably the
2301 only MTA that supported it -- and would never use it because real RSA is
2302 always available. This code has been removed, because it had the bad
2303 effect of slowing Exim down by computing (never used) parameters for the
2304 RSA_EXPORT functionality.

2310 if the connection is using TLS or if the remote IP is the same as the
2311 local IP, and the "valid-client-cert option" if a client certificate has

2343
2344PH/30 Exim was sometimes attempting to deliver messages that had suffered
2345 address errors (4xx response to RCPT) over the same connection as other
2346 messages routed to the same hosts. Such deliveries are always "forced",
2347 so retry times are not inspected. This resulted in far too many retries
2348 for the affected addresses. The effect occurred only when there were more
2349 hosts than the hosts_max_try setting in the smtp transport when it had
2350 the 4xx errors. Those hosts that it had tried were not added to the list
2351 of hosts for which the message was waiting, so if all were tried, there
2352 was no problem. Two fixes have been applied:
2353
2354 (i) If there are any address or message errors in an SMTP delivery, none
2355 of the hosts (tried or untried) are now added to the list of hosts
2356 for which the message is waiting, so the message should not be a
2357 candidate for sending over the same connection that was used for a
2358 successful delivery of some other message. This seems entirely
2359 reasonable: after all the message is NOT "waiting for some host".
2360 This is so "obvious" that I'm not sure why it wasn't done
2361 previously. Hope I haven't missed anything, but it can't do any
2362 harm, as the worst effect is to miss an optimization.
2363
2364 (ii) If, despite (i), such a delivery is accidentally attempted, the
2365 routing retry time is respected, so at least it doesn't keep
2366 hammering the server.

2381PH/35 The error "getsockname() failed: connection reset by peer" was being
2382 written to the panic log as well as the main log, but it isn't really
2383 panic-worthy as it just means the connection died rather early on. I have
2384 removed the panic log writing for the ECONNRESET error when getsockname()
2385 fails.
2386
48c7f9e2
PH
2387PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2388 runs only) independently of the message's sender address. This meant
2389 that, if the 4xx error was in fact related to the sender, a different
2390 message to the same recipient with a different sender could confuse
2391 things. In particualar, this can happen when sending to a greylisting
2392 server, but other circumstances could also provoke similar problems.
2393 I have changed the default so that the retry time for these errors is now
2394 based a combination of the sender and recipient addresses. This change
2395 can be overridden by setting address_retry_include_sender=false in the
2396 smtp transport.

2757 autoreply, Exim could try to deliver to a non-existent relative file

2759 it logs this as a hard delivery error, but does not attempt to create a

2777 non-existent - all you got was a failure to exec. I have made two
2778 changes:
2779
2780 (a) Failures to set uid/gid, the current directory, or a process leader
2781 in a subprocess such as that created by queryprogram now generate
2782 suitable debugging ouput when -d is set.
2783

2786 the subprocess without attempting to change uid/gid.

2791PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2792 additional section of a DNS packet that returns MX or SRV records.
2793 Instead, it always explicitly searches for A/AAAA records. This avoids
2794 major problems that occur when a DNS server includes only records of one
2795 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2796 fixed another bug: if SRV records were looked up and the corresponding
2797 address records were *not* found in the additional section, the port
2798 values from the SRV records were lost.

2800PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2808PH/19 When calculating a retry time, Exim used to measure the "time since
2809 failure" by looking at the "first failed" field in the retry record. Now
2810 it does not use this if it is later than than the arrival time of the
2811 message. Instead it uses the arrival time. This makes for better
2812 behaviour in cases where some deliveries succeed, thus re-setting the
2813 "first failed" field. An example is a quota failure for a huge message
2814 when small messages continue to be delivered. Without this change, the
2815 "time since failure" will always be short, possible causing more frequent
2816 delivery attempts for the huge message than are intended.

PH
2913PH/42 The content-scanning code uses fopen() to create files in which to put
2914 message data. Previously it was not paying any attention to the mode of
2915 the files. Exim runs with umask(0) because the rest of the code creates
2916 files with open(), and sets the required mode explicitly. Thus, these
2917 files were ending up world-writeable. This was not a big issue, because,
2918 being within the spool directory, they were not world-accessible. I have
2919 created a function called modefopen, which takes an additional mode
2920 argument. It sets umask(777), creates the file, chmods it to the required
2921 mode, then resets the umask. All the relevant calls to fopen() in the
2922 content scanning code have been changed to use this function.

2934 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2959
2960 (i) Exim was not creating retry information for temporary errors given
2961 for individual recipients after the DATA command when the smtp transport
2962 was used in LMTP mode. This meant that they could be retried too
2963 frequently, and not timed out correctly.
2964
2965 (ii) Exim was setting the flag that allows error details to be returned
2966 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2967 recipients that were returned after the DATA command.
2968
2969PH/53 This is related to PH/52, but is more general: for any failing address,
2970 when detailed error information was permitted to be returned to the
2971 sender, but the error was temporary, then after the final timeout, only
2972 "retry timeout exceeded" was returned. Now it returns the full error as

3043PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3044 function verify_get_ident() calls ip_connect() to connect a socket, but
3045 if the "connect()" function timed out, ip_connect() used to close the
3046 socket. However, verify_get_ident() also closes the socket later, and in
3047 between Exim writes to the log, which may get opened at this point. When
3048 the socket was closed in ip_connect(), the log could get the same file
3049 descriptor number as the socket. This naturally causes chaos. The fix is
3050 not to close the socket in ip_connect(); the socket should be closed by
3051 the function that creates it. There was only one place in the code where
3052 this was missing, in the iplookup router, which I don't think anybody now
3053 uses, but I've fixed it anyway.

3109PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3110 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3111 not being looked up in the rDNS to get a host name, Exim was showing the
3112 IP address twice in Received: lines, even though the IP addresses were
3113 identical. For example:
3114
3115 Received: from [1.2.3.4] (helo=[1.2.3.4])
3116
3117 However, if the real host name was known, it was omitting the HELO data
3118 if it matched the actual IP address. This has been tidied up so that it
3119 doesn't show the same IP address twice.

3121PH/07 When both +timestamp and +memory debugging was on, the value given by
3122 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3123 called by the debug printing, thereby overwriting the timestamp buffer.
3124 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3145PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3146 Electronic Mail") by including:
3147
3148 Auto-submitted: auto-generated
3149
3150 in the messages that it generates (bounce messages and others, such as
3151 warnings). In the case of bounce messages for non-SMTP mesages, there was
3152 also a typo: it was using "Auto_submitted" (underscore instead of
3153 hyphen). Since every message generated by Exim is necessarily in response
3154 to another message, thes have all been changed to:
3155
3156 Auto-Submitted: auto-replied
3157
3158 in accordance with these statements in the RFC:
3159
3160 The auto-replied keyword:
3161
3162 - SHOULD be used on messages sent in direct response to another
3163 message by an automatic process,
3164
3165 - MUST NOT be used on manually-generated messages,
3166
3167 - MAY be used on Delivery Status Notifications (DSNs) and Message
3168 Disposition Notifications (MDNs),
3169
3170 - MUST NOT be used on messages generated by automatic or periodic
3171 processes, except for messages which are automatic responses to
3172 other messages.

3193PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3194 extension "envelope-auth". The code is finished and in agreement with
3195 other implementations, but there is no documentation so far and in fact,
3196 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3197 not changing the active code.
3198
3199 Print executed "if" and "elsif" statements when debugging is used. This
3200 helps a great deal to understand what a filter does.
3201
3202 Document more things not specified clearly in RFC3028. I had all this
3203 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3208PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3209 canonical form (as documented). However, after a host name lookup from
3210 the IP address, check_host() was doing a simple string comparison with
3211 addresses acquired from the DNS when checking that the found name did
3212 have the original IP as one of its addresses. Since any found IPv6
3213 addresses are likely to be in abbreviated form, the comparison could
3214 fail. Luckily, there already exists a function for doing the comparison
3215 by converting both addresses to binary, so now that is used instead of
3216 the text comparison.
3217
96776534
PH
3218PH/20 There was another similar case to PH/19, when a complete host name was
3219 given in a host list; looking up its IP address could give an abbreviated
3220 form, whereas the current host's name might or might not be abbreviated.
3221 The same fix has been applied.

3300PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true

3304 not happened, "verify = helo" does it there and then.
