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
JH
26JH/05 If main configuration option tls_certificate is unset, generate a
27 selfsigned certificate for inbound TLS connections.
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
d7bed771 93JH/25 Decoding ACL controls is now done using a binary search; the sourcecode
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.

121Exim version 4.87
122-----------------
82d14d6a
JH
123JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
124 and 3.4.4 - once the server is enabled to respond to an OCSP request
125 it does even when not requested, resulting in a stapling non-aware
126 client dropping the TLS connection.
0d9b78be 127
6c6d6e48
TF
128TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
129 support variable-length bit vectors. No functional change.
130
ac881e27
TF
131TF/02 Improve the consistency of logging incoming and outgoing interfaces.
132 The I= interface field on outgoing lines is now after the H= remote
133 host field, same as incoming lines. There is a separate
134 outgoing_interface log selector which allows you to disable the
135 outgoing I= field.
136
c8899c20
JH
137JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
138 If not running log_selector +smtp_connection the mainlog would be held
139 open indefinitely after a "too many connections" event, including to a
140 deleted file after a log rotate. Leave the per net connection logging
141 leaving it open for efficiency as that will be quickly detected by the
142 check on the next write.
143
f1b81d81
HSHR
144HS/01 Bug 1671: Fix post transport crash.
145 Processing the wait-<transport> messages could crash the delivery
146 process if the message IDs didn't exist for some reason. When
147 using 'split_spool_directory=yes' the construction of the spool
148 file name failed already, exposing the same netto behaviour.
149
f38917cc
JH
150JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
151 mime_regex ACL conditions.
152
895fbaf2
JH
153JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
154 to DSN fail messages (bounces): remote IP, remote greeting, remote response
155 to HELO, local diagnostic string.
156
805bb5c3
JH
157JH/05 Downgrade message for a TLS-certificate-based authentication fail from
158 log line to debug. Even when configured with a tls authenticator many
159 client connections are expected to not authenticate in this way, so
160 an authenticate fail is not an error.
161
56c2a7be
HSHR
162HS/02 Add the Exim version string to the process info. This way exiwhat
163 gives some more detail about the running daemon.
164
14b3c5bc
JH
165JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
166 matter for fast-change records such as DNSBLs.
167
6f6dedcc
JH
168JH/07 Bug 1678: Always record an interface option value, if set, as part of a
169 retry record, even if constant. There may be multiple transports with
170 different interface settings and the retry behaviour needs to be kept
171 distinct.
172
0f557e90
JH
173JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
174
175JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
176
ec0eb1a3
JH
177JH/10 Bug 840: fix log_defer_output option of pipe transport
178
41e93589
JH
179JH/11 Bug 830: use same host for all RCPTS of a message, even under
180 hosts_randomize. This matters a lot when combined with mua_wrapper.
181
98b98887 182JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
183 ${quote_pgsql:<string>} operator.
184
98b98887
JH
185JH/13 Bug 1708: avoid misaligned access in cached lookup.
186
858e91c2
JH
187JH/14 Change header file name for freeradius-client. Relevant if compiling
188 with Radius support; from the Gentoo tree and checked under Fedora.
189
190JH/15 Bug 1712: Introduce $prdr_requested flag variable
191
6ff55e50
JH
192JH/16 Bug 1714: Permit an empty string as expansion result for transport
193 option transport_filter, meaning no filtering.
194
3b957582
JB
195JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
196
23f3dc67
JH
197JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
198 defaults to "*" (all hosts). The variable is now available when not built
199 with TLS, default unset, mainly to enable keeping the testuite sane.
200 If a server certificate is not supplied (via tls_certificate) an error is
201 logged, and clients will find TLS connections fail on startup. Presumably
202 they will retry in-clear.
203 Packagers of Exim are strongly encouraged to create a server certificate
204 at installation time.
205
240c288f
JH
206HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
207 with the $config_file variable.
208
5ef5dd52
JB
209JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
210 in transport context, after the attempt, and per-recipient. The latter type
211 is per host attempted. The event data is the error message, and the errno
212 information encodes the lookup type (A vs. MX) used for the (first) host,
213 and the trailing two digits of the smtp 4xx reponse.
214
e161710d
GF
215GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
216 to write to mainlog (or rejectlog, paniclog) in the window between file
217 creation and permissions/ownership being changed. Particularly affects
218 installations where exicyclog is run as root, rather than exim user;
219 result is that the running daemon panics and dies.
220
a159f203
JH
221JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
222
7f06582c
JH
223JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
224 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
225 "pri" and "weight". Note that the previous implicit priority given by the
226 list order is no longer honoured.
227
abe1010c
JH
228JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
229 for DKIM processing.

JH
231JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
232 by defining SUPPORT_SOCKS.
74f150bf 233
cee5f132
JH
234JH/26 Move PROXY support from Experimental to mainline, enabled for a build
235 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
236 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
237 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 238
8c5d388a
JH
239JH/27 Move Internationalisation support from Experimental to mainline, enabled
240 for a build by defining SUPPORT_I18N
241
2d8d625b
JH
242JH/28 Bug 1745: Fix redis lookups to handle (quoted) spaces embedded in parts
243 of the query string, and make ${quote_redis:} do that quoting.
244
0cbf2b82
JH
245JH/29 Move Events support from Experimental to mainline, enabled by default
246 and removable for a build by defining DISABLE_EVENT.

JH
250JH/31 Fix bug with hosts_connection_nolog and named-lists which were wrongly
251 cached by the daemon.
252
de78e2d5
JH
253JH/32 Move Redis support from Experimental to mainline, enabled for a build
254 by defining LOOKUP_REDIS. The libhiredis library is required.
255
379ba7d0
JH
256JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
257 keys are given for lookup.
258
f444c2c7
JH
259JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
260 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
261 only supported when built with TLS support. The PolarSSL SHA routines
262 are still used when the TLS library is too old for convenient support.
f444c2c7 263
a57b6200
JH
264JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
265 openssl_options), for security. OpenSSL forces this from version 1.1.0
266 server-side so match that on older versions.
267
07c73177 268JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 269 allocation for $value could be released as the expansion processing
07c73177 270 concluded, but leaving the global pointer active for it.
fa01e4f8 271
4f6ae5c3
JH
272JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
273 and to use the domains and local_parts ACL conditions.
274
1bc460a6
JH
275JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
276 incorrectly not doubled on cutthrough transmission, hence seen as a
277 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 278 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
279 via the normal store-and-forward channel. This could result in duplicates
280 received - but deduplicating mailstores were liable to retain only the
281 initial truncated version.
282
ab9152ff 283JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.
df3def24 284

JH
285JH/40 Fix crash in queryprogram router when compiled with EXPERIMENTAL_SRS.
286
ab9152ff
JH
287JH/41 Bug 1792: Fix selection of headers to sign for DKIM: bottom-up. While
288 we're in there, support oversigning also; bug 1309.
289
af483912
JH
290JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.
291
bc3c7bb7 292HS/04 Add support for keep_environment and add_environment options.
df3def24 293
13559da6
JH
294JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
295 either intentional arithmetic overflow during PRNG, or testing config-
296 induced overflows.
297
59eaad2b
JH
298JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
299 delivery resulted in actual delivery. Cancel cutthrough before DATA
300 stage.
301
f9334a28
JH
302JH/45 Fix cutthrough, when connection not opened by verify and target hard-
303 rejects a recipient: pass the reject to the originator.
304
dc8091e7
JH
305JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
306 Many were false-positives and ignorable, but it's worth fixing the
307 former class.
308
dfe7d917
JH
309JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
310 for the new environment-manipulation done at startup. Move the routines
311 from being local to tls.c to being global via the os.c file.
312
93cc2d6e
JH
313JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
314 an extract embedded as result-arg for a map, the first arg for extract
315 is unavailable so we cannot tell if this is a numbered or keyed
316 extraction. Accept either.

325JH/02 The smtp transport option "multi_domain" is now expanded.
326
ad07e9ad
JH
327JH/03 The smtp transport now requests PRDR by default, if the server offers
328 it.
329
01a4a5c5 330JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 331 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
332 can be used to disable this per-host. The build option
333 EXPERIMENTAL_CERTNAMES is withdrawn.
334
cb1d7830 335JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 336 default to the word "system" to access the system default CA bundle.

JH
337 For GnuTLS, only version 3.0.20 or later.
338
610ff438 339JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
340 (but not required) by default. The verification status is now logged by
341 default, for both outbound TLS and client-certificate supplying inbound
342 TLS connections
610ff438 343
f926e272
JH
344JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
345 sites use this now.
346
50dc7409
JH
347JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
348 Status Notification (bounce) messages are now MIME format per RFC 3464.
349 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
350 under the control of the dsn_advertise_hosts option, and routers may
351 have a dsn_lasthop option.
352
0f0c8159
JH
353JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
354 default, modifiable by a malware= option. The list separator for
23763898 355 the options can now be changed in the usual way. Bug 68.
4e71661f 356
1ad6489e
JH
357JH/10 The smtp_receive_timeout main option is now expanded before use.
358
aeaf5db3

359JH/11 The incoming_interface log option now also enables logging of the
360 local interface on delivery outgoing connections.
361
5032d1cf
JH
362JH/12 The cutthrough-routing facility now supports multi-recipient mails,
363 if the interface and destination host and port all match.
364
7e8360e6
JH
365JH/13 Bug 344: The verify = reverse_host_lookup ACL condition now accepts a
366 /defer_ok option.

368JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
369 Patch from Andrew Lewis.
370
fd4d8871 371JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 372 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
373 modifiers per server. Patch originally by <rommer@active.by>.
374
375JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
376 and remote servers. Remote servers can be IPv6 addresses, and
377 specify a port-range.
fd4d8871 378
23763898

807TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
808
809 When a queue runner is handling a message, Exim first routes the
810 recipient addresses, during which it prunes them based on the retry
811 hints database. After that it attempts to deliver the message to
812 any remaining recipients. It then updates the hints database using
813 the retry rules.
814
815 So if a recipient address works intermittently, it can get repeatedly
816 deferred at routing time. The retry hints record remains fresh so the
817 address never reaches the final cutoff time.
818
819 This is a fairly common occurrence when a user is bumping up against
820 their storage quota. Exim had some logic in its local delivery code
821 to deal with this. However it did not apply to per-recipient defers
822 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
823
1ddeb334
TF
824 This change adds a proper retry rule check during routing so that the
825 final cutoff time is checked against the message's age. We only do
826 this check if there is an address retry record and there is not a
827 domain retry record; this implies that previous attempts to handle
828 the address had the retry_use_local_parts option turned on. We use
829 this as an approximation for the destination being like a local
830 delivery, as in LMTP.
67bd1ab3
TF
831
832 I suspect this new check makes the old local delivery cutoff check
833 redundant, but I have not verified this so I left the code in place.

841 When I ran the test suite under the user fanf2, Exim expanded
842 the header to contain my full name, whereas it should have added
843 a Resent-Sender: header. It erroneously treats any prefix of the
844 username as equal to the username.

868 Server implementation by Todd Lyons, client by JH.
869 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
870 config variable "prdr_enable" controls whether the server
871 advertises the facility. If the client requests PRDR a new
872 acl_data_smtp_prdr ACL is called once for each recipient, after
873 the body content is received and before the acl_smtp_data ACL.
874 The client is controlled by bolth of: a hosts_try_prdr option
875 on the smtp transport, and the server advertisement.
876 Default client logging of deliveries and rejections involving
877 PRDR are flagged with the string "PRDR".

1155TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1156 lock up or crash if it happened to be inside a call to libc when it
1157 got a SIGUSR1 from exiwhat.
1158
1159 The SIGUSR1 handler appends the current process status to the process
1160 log which is later printed by exiwhat. It used to use the general
1161 purpose logging code to do this, but several functions it calls are
1162 not safe for signals.
1163
1164 The new output code in the SIGUSR1 handler is specific to the process
1165 log, and simple enough that it's easy to inspect for signal safety.
1166 Removing some special cases also simplifies the general logging code.
1167 Removing the spurious timestamps from the process log simplifies
1168 exiwhat.

TF
1170TF/04 Improved ratelimit ACL condition.
1171
1172 The /noupdate option has been deprecated in favour of /readonly which
1173 has clearer semantics. The /leaky, /strict, and /readonly update modes
1174 are mutually exclusive. The update mode is no longer included in the
1175 database key; it just determines when the database is updated. (This
1176 means that when you upgrde Exim will forget old rate measurements.)
1177
1178 Exim now checks that the per_* options are used with an update mode that
1179 makes sense for the current ACL. For example, when Exim is processing a
1180 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1181 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1182 must specify per_mail/readonly. If you omit the update mode it defaults to
1183 /leaky where that makes sense (as before) or /readonly where required.
1184
1185 The /noupdate option is now undocumented but still supported for
1186 backwards compatibility. It is equivalent to /readonly except that in
1187 ACLs where /readonly is required you may specify /leaky/noupdate or
1188 /strict/noupdate which are treated the same as /readonly.
1189
1190 A useful new feature is the /count= option. This is a generalization
1191 of the per_byte option, so that you can measure the throughput of other
1192 aggregate values. For example, the per_byte option is now equivalent
1193 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1194
1195 The per_rcpt option has been generalized using the /count= mechanism
1196 (though it's more complicated than the per_byte equivalence). When it is
1197 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1198 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1199 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1200 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1201 Note that using per_rcpt with a non-readonly update mode in more than
1202 one ACL will cause the recipients to be double-counted. (The per_mail
1203 and per_byte options don't have this problem.)
1204
1205 The handling of very low rates has changed slightly. If the computed rate
1206 is less than the event's count (usually one) then this event is the first
1207 after a long gap. In this case the rate is set to the same as this event's
1208 count, so that the first message of a spam run is counted properly.
1209
1210 The major new feature is a mechanism for counting the rate of unique
1211 events. The new per_addr option counts the number of different
1212 recipients that someone has sent messages to in the last time period. It
1213 behaves like per_rcpt if all the recipient addresses are different, but
1214 duplicate recipient addresses do not increase the measured rate. Like
1215 the /count= option this is a general mechanism, so the per_addr option
1216 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1217 example, measure the rate that a client uses different sender addresses
1218 with the options per_mail/unique=$sender_address. There are further
1219 details in the main documentation.

1770 were called 'true' and it seems that C99 defines that as a reserved

1791PH/01 Another patch from the Sieve maintainer.
1792
6a3bceb1
PH
1793PH/02 When an IPv6 address is converted to a string for single-key lookup
1794 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1795 dots are used instead of colons so that keys in lsearch files need not
1796 contain colons. This was done some time before quoting was made available
1797 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1798 (notated using the quote facility) so as to distinguish them from IPv4
1799 keys. This meant that lookups for IP addresses in host lists did not work
1800 for iplsearch lookups.
1801
1802 This has been fixed by arranging for IPv6 addresses to be expressed with
1803 colons if the lookup type is iplsearch. This is not incompatible, because
1804 previously such lookups could never work.
1805
1806 The situation is now rather anomolous, since one *can* have colons in
1807 ordinary lsearch keys. However, making the change in all cases is
1808 incompatible and would probably break a number of configurations.

1813MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1814 conversion specification without a maximum field width, thereby enabling
1815 a rogue spamd server to cause a buffer overflow. While nobody in their
1816 right mind would setup Exim to query an untrusted spamd server, an
1817 attacker that gains access to a server running spamd could potentially
1818 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1823MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1824 a directory entry by the name of the lookup key. Previously, if a
1825 symlink pointed to a non-existing file or a file in a directory that
1826 Exim lacked permissions to read, a lookup for a key matching that
1827 symlink would fail. Now it is enough that a matching directory entry
1828 exists, symlink or not. (Bugzilla 503.)

2011PH/29 SMTP synchronization checks are implemented when a command is read -
2012 there is a check that no more input is waiting when there shouldn't be

2014 some time before the response is written. In this time, more input might
2015 arrive, invalidly. So now there are extra checks after an ACL has run for
2016 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2017 pipelining has not been advertised.

PH
2091 the response to the final '.' that terminates a message, but only in the
2092 case where the client has not sent further data following the '.'
2093 (unfortunately, this is allowed). However, in many cases there won't be
2094 any further data because there won't be any more messages to send. A call
2095 to select() can be used: if it shows that the input is "ready", there is
2096 either input waiting, or the socket has been closed. An attempt to read
2097 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2098 would have sent an OK response which the client would never have see.

2109PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2110 fixed by 4.65/MH/01 (is this a record?) are fixed:
2111
2112 (i) An empty string was always treated as zero by the numeric comparison
2113 operators. This behaviour has been restored.
2114
2115 (ii) It is documented that the numeric comparison operators always treat
2116 their arguments as decimal numbers. This was broken in that numbers
2117 starting with 0 were being interpreted as octal.
2118
2119 While fixing these problems I realized that there was another issue that
2120 hadn't been noticed. Values of message_size_limit (both the global option
2121 and the transport option) were treated as octal if they started with 0.
2122 The documentation was vague. These values are now always treated as
2123 decimal, and I will make that clear in the documentation.

2139 is held in a short int, deliveries were likely to be lost. As such a
2140 large number of recipients for a single message is ridiculous

PH
2167PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2168 callout verification, Exim cached a "reject" for the entire domain. This
2169 is correct for most verifications, but it is not correct for a recipient
2170 verification with use_sender or use_postmaster set, because in that case
2171 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2172 case of MAIL FROM:<> rejection from other early rejections (e.g.
2173 rejection of HELO). When verifying a recipient using a non-null MAIL
2174 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2175 Whatever the result of the callout, the value of the domain cache is
2176 left unchanged (for any other kind of callout, getting as far as trying
2177 RCPT means that the domain itself is ok).

2211PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2213 probably the interface on which it is arriving) and not to the outgoing
2214 callout (which could be using a different interface). This has been
2215 changed to use the value of the helo_data option from the smtp transport
2216 instead - this is what is used when a message is actually being sent. If
2217 there is no remote transport (possible with a router that sets up host
2218 addresses), $smtp_active_hostname is used.

7befa435 2221 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2222 (a) The code assumed that strncpy() returns a negative number on buffer
2223 overflow, which isn't the case. Replaced with Exim's string_format()
2224 function.
2225 (b) There were several signed/unsigned issues. I just did the minimum
2226 hacking in of casts. There is scope for a larger refactoring.
2227 (c) The code used strcasecmp() which is not a standard C function.
2228 Replaced with Exim's strcmpic() function.
2229 (d) The code set only $1; it now sets $auth1 as well.
2230 (e) A simple test gave the error "authentication client didn't specify
2231 service in request". It would seem that Dovecot has changed its
2232 interface. Fortunately there's a specification; I followed it and
2233 changed what the client sends and it appears to be working now.

2239 address A is aliased to B and C, where B exists and C does not. Without
2240 -v the output is "A verified" because verification stops after a
2241 successful redirection if more than one address is generated. However,
2242 with -v the child addresses are also verified. Exim was outputting "A
2243 failed to verify" and then showing the successful verification for C,
2244 with its parentage. It now outputs "B failed to verify", showing B's
2245 parentage before showing the successful verification of C.

2250
322050c2
PH
2251PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2252 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2253 they consult the DNS. I had assumed they would set it the way they
2254 wanted; and indeed my experiments on Linux seem to show that in some
2255 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2256 To be on the safe side, however, I have now made the interface to
2257 host_find_byname() similar to host_find_bydns(), with an argument
2258 containing the DNS resolver options. The host_find_byname() function now
2259 sets these options at its start, just as host_find_bydns() does. The smtp
2260 transport options dns_qualify_single and dns_search_parents are passed to
2261 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2262 of host_find_byname() use the default settings of RES_DEFNAMES
2263 (qualify_single) but not RES_DNSRCH (search_parents).

2265PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2266 spool_read_header() do less string testing, by means of a preliminary
2267 switch on the second character of optional "-foo" lines. (This is
2268 overdue, caused by the large number of possibilities that now exist.
2269 Originally there were few.) While I was there, I also converted the
2270 str(n)cmp tests so they don't re-test the leading "-" and the first
2271 character, in the hope this might squeeze out yet more improvement.

2273PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2274 flag allowing group syntax was set by the header_syntax check but not
2275 turned off, possible causing trouble later; (2) The flag was not being
2276 set at all for the header_verify test, causing "group"-style headers to
2277 be rejected. I have now set it in this case, and also caused header_
2278 verify to ignore an empty address taken from a group. While doing this, I
2279 came across some other cases where the code for allowing group syntax
2280 while scanning a header line wasn't quite right (mostly, not resetting
2281 the flag correctly in the right place). These bugs could have caused
2282 trouble for malformed header lines. I hope it is now all correct.

PH
2284PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2287 but it didn't always do it. This confused somebody who was copying the
2288 code for some other use. I have removed all the tests.

PH
2290PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

2293 only MTA that supported it -- and would never use it because real RSA is
2294 always available. This code has been removed, because it had the bad
2295 effect of slowing Exim down by computing (never used) parameters for the
2296 RSA_EXPORT functionality.

2303 local IP, and the "valid-client-cert option" if a client certificate has

2336PH/30 Exim was sometimes attempting to deliver messages that had suffered
2337 address errors (4xx response to RCPT) over the same connection as other
2338 messages routed to the same hosts. Such deliveries are always "forced",
2339 so retry times are not inspected. This resulted in far too many retries
2340 for the affected addresses. The effect occurred only when there were more
2341 hosts than the hosts_max_try setting in the smtp transport when it had
2342 the 4xx errors. Those hosts that it had tried were not added to the list
2343 of hosts for which the message was waiting, so if all were tried, there
2344 was no problem. Two fixes have been applied:
2345
2346 (i) If there are any address or message errors in an SMTP delivery, none
2347 of the hosts (tried or untried) are now added to the list of hosts
2348 for which the message is waiting, so the message should not be a
2349 candidate for sending over the same connection that was used for a
2350 successful delivery of some other message. This seems entirely
2351 reasonable: after all the message is NOT "waiting for some host".
2352 This is so "obvious" that I'm not sure why it wasn't done
2353 previously. Hope I haven't missed anything, but it can't do any
2354 harm, as the worst effect is to miss an optimization.
2355
2356 (ii) If, despite (i), such a delivery is accidentally attempted, the
2357 routing retry time is respected, so at least it doesn't keep
2358 hammering the server.

2373PH/35 The error "getsockname() failed: connection reset by peer" was being
2374 written to the panic log as well as the main log, but it isn't really
2375 panic-worthy as it just means the connection died rather early on. I have
2376 removed the panic log writing for the ECONNRESET error when getsockname()
2377 fails.

48c7f9e2
PH
2379PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2380 runs only) independently of the message's sender address. This meant
2381 that, if the 4xx error was in fact related to the sender, a different
2382 message to the same recipient with a different sender could confuse
2383 things. In particualar, this can happen when sending to a greylisting
2384 server, but other circumstances could also provoke similar problems.
2385 I have changed the default so that the retry time for these errors is now
2386 based a combination of the sender and recipient addresses. This change
2387 can be overridden by setting address_retry_include_sender=false in the
2388 smtp transport.

2662 554 error is used if errno is still zero or contains ENOENT (which occurs

2749 autoreply, Exim could try to deliver to a non-existent relative file

2751 it logs this as a hard delivery error, but does not attempt to create a

2769 non-existent - all you got was a failure to exec. I have made two
2770 changes:
2771
2772 (a) Failures to set uid/gid, the current directory, or a process leader
2773 in a subprocess such as that created by queryprogram now generate
2774 suitable debugging ouput when -d is set.

2778 the subprocess without attempting to change uid/gid.

2783PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2784 additional section of a DNS packet that returns MX or SRV records.
2785 Instead, it always explicitly searches for A/AAAA records. This avoids
2786 major problems that occur when a DNS server includes only records of one
2787 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2788 fixed another bug: if SRV records were looked up and the corresponding
2789 address records were *not* found in the additional section, the port
2790 values from the SRV records were lost.

PH
2800PH/19 When calculating a retry time, Exim used to measure the "time since
2801 failure" by looking at the "first failed" field in the retry record. Now
2802 it does not use this if it is later than than the arrival time of the
2803 message. Instead it uses the arrival time. This makes for better
2804 behaviour in cases where some deliveries succeed, thus re-setting the
2805 "first failed" field. An example is a quota failure for a huge message
2806 when small messages continue to be delivered. Without this change, the
2807 "time since failure" will always be short, possible causing more frequent
2808 delivery attempts for the huge message than are intended.

PH
2905PH/42 The content-scanning code uses fopen() to create files in which to put
2906 message data. Previously it was not paying any attention to the mode of
2907 the files. Exim runs with umask(0) because the rest of the code creates
2908 files with open(), and sets the required mode explicitly. Thus, these
2909 files were ending up world-writeable. This was not a big issue, because,
2910 being within the spool directory, they were not world-accessible. I have
2911 created a function called modefopen, which takes an additional mode
2912 argument. It sets umask(777), creates the file, chmods it to the required
2913 mode, then resets the umask. All the relevant calls to fopen() in the
2914 content scanning code have been changed to use this function.

2951
2952 (i) Exim was not creating retry information for temporary errors given
2953 for individual recipients after the DATA command when the smtp transport
2954 was used in LMTP mode. This meant that they could be retried too
2955 frequently, and not timed out correctly.
2956
2957 (ii) Exim was setting the flag that allows error details to be returned
2958 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2959 recipients that were returned after the DATA command.
2960
2961PH/53 This is related to PH/52, but is more general: for any failing address,
2962 when detailed error information was permitted to be returned to the
2963 sender, but the error was temporary, then after the final timeout, only

3036 function verify_get_ident() calls ip_connect() to connect a socket, but
3037 if the "connect()" function timed out, ip_connect() used to close the
3038 socket. However, verify_get_ident() also closes the socket later, and in
3039 between Exim writes to the log, which may get opened at this point. When
3040 the socket was closed in ip_connect(), the log could get the same file
3041 descriptor number as the socket. This naturally causes chaos. The fix is
3042 not to close the socket in ip_connect(); the socket should be closed by
3043 the function that creates it. There was only one place in the code where
3044 this was missing, in the iplookup router, which I don't think anybody now
3045 uses, but I've fixed it anyway.

3074 because their memory is reclaimed, so using them afterwards may do
3075 silly things.

3104 IP address twice in Received: lines, even though the IP addresses were
3105 identical. For example:
3106
3107 Received: from [1.2.3.4] (helo=[1.2.3.4])

3113PH/07 When both +timestamp and +memory debugging was on, the value given by
3114 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3115 called by the debug printing, thereby overwriting the timestamp buffer.
3116 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3137PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3138 Electronic Mail") by including:
3139
3140 Auto-submitted: auto-generated
3141
3142 in the messages that it generates (bounce messages and others, such as
3143 warnings). In the case of bounce messages for non-SMTP mesages, there was
3144 also a typo: it was using "Auto_submitted" (underscore instead of
3145 hyphen). Since every message generated by Exim is necessarily in response
3146 to another message, thes have all been changed to:
3147
3148 Auto-Submitted: auto-replied
3149
3150 in accordance with these statements in the RFC:
3151
3152 The auto-replied keyword:
3153
3154 - SHOULD be used on messages sent in direct response to another
3155 message by an automatic process,
3156
3157 - MUST NOT be used on manually-generated messages,
3158
3159 - MAY be used on Delivery Status Notifications (DSNs) and Message
3160 Disposition Notifications (MDNs),
3161
3162 - MUST NOT be used on messages generated by automatic or periodic
3163 processes, except for messages which are automatic responses to
3164 other messages.

3185PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3186 extension "envelope-auth". The code is finished and in agreement with
3187 other implementations, but there is no documentation so far and in fact,
3188 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3189 not changing the active code.
3190
3191 Print executed "if" and "elsif" statements when debugging is used. This
3192 helps a great deal to understand what a filter does.

3195 sorted out, when out of a sudden new issues came to my mind. Oops."

3200PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3201 canonical form (as documented). However, after a host name lookup from
3202 the IP address, check_host() was doing a simple string comparison with
3203 addresses acquired from the DNS when checking that the found name did
3204 have the original IP as one of its addresses. Since any found IPv6
3205 addresses are likely to be in abbreviated form, the comparison could
3206 fail. Luckily, there already exists a function for doing the comparison
3207 by converting both addresses to binary, so now that is used instead of
3208 the text comparison.
3209

PH
3210PH/20 There was another similar case to PH/19, when a complete host name was
3211 given in a host list; looking up its IP address could give an abbreviated
3212 form, whereas the current host's name might or might not be abbreviated.
3213 The same fix has been applied.
