4Exim version 4.88
5-----------------

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

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.

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.

112Exim version 4.87
113-----------------
82d14d6a
JH
114JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
115 and 3.4.4 - once the server is enabled to respond to an OCSP request
116 it does even when not requested, resulting in a stapling non-aware
117 client dropping the TLS connection.
0d9b78be 118
6c6d6e48
TF
119TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
120 support variable-length bit vectors. No functional change.
121
ac881e27
TF
122TF/02 Improve the consistency of logging incoming and outgoing interfaces.
123 The I= interface field on outgoing lines is now after the H= remote
124 host field, same as incoming lines. There is a separate
125 outgoing_interface log selector which allows you to disable the
126 outgoing I= field.
127
c8899c20
JH
128JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
129 If not running log_selector +smtp_connection the mainlog would be held
130 open indefinitely after a "too many connections" event, including to a
131 deleted file after a log rotate. Leave the per net connection logging
132 leaving it open for efficiency as that will be quickly detected by the
133 check on the next write.
134
f1b81d81
HSHR
135HS/01 Bug 1671: Fix post transport crash.
136 Processing the wait-<transport> messages could crash the delivery
137 process if the message IDs didn't exist for some reason. When
138 using 'split_spool_directory=yes' the construction of the spool
139 file name failed already, exposing the same netto behaviour.
140
f38917cc
JH
141JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
142 mime_regex ACL conditions.
143
895fbaf2
JH
144JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
145 to DSN fail messages (bounces): remote IP, remote greeting, remote response
146 to HELO, local diagnostic string.
147
805bb5c3
JH
148JH/05 Downgrade message for a TLS-certificate-based authentication fail from
149 log line to debug. Even when configured with a tls authenticator many
150 client connections are expected to not authenticate in this way, so
151 an authenticate fail is not an error.
152
56c2a7be
HSHR
153HS/02 Add the Exim version string to the process info. This way exiwhat
154 gives some more detail about the running daemon.
155
14b3c5bc
JH
156JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
157 matter for fast-change records such as DNSBLs.
158
6f6dedcc
JH
159JH/07 Bug 1678: Always record an interface option value, if set, as part of a
160 retry record, even if constant. There may be multiple transports with
161 different interface settings and the retry behaviour needs to be kept
162 distinct.
163
0f557e90
JH
164JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
165
166JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
167
ec0eb1a3
JH
168JH/10 Bug 840: fix log_defer_output option of pipe transport
169
41e93589
JH
170JH/11 Bug 830: use same host for all RCPTS of a message, even under
171 hosts_randomize. This matters a lot when combined with mua_wrapper.
172
98b98887 173JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
174 ${quote_pgsql:<string>} operator.
175
98b98887
JH
176JH/13 Bug 1708: avoid misaligned access in cached lookup.
177
858e91c2
JH
178JH/14 Change header file name for freeradius-client. Relevant if compiling
179 with Radius support; from the Gentoo tree and checked under Fedora.
180
181JH/15 Bug 1712: Introduce $prdr_requested flag variable
182
6ff55e50
JH
183JH/16 Bug 1714: Permit an empty string as expansion result for transport
184 option transport_filter, meaning no filtering.
185
3b957582
JB
186JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
187
23f3dc67
JH
188JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
189 defaults to "*" (all hosts). The variable is now available when not built
190 with TLS, default unset, mainly to enable keeping the testuite sane.
191 If a server certificate is not supplied (via tls_certificate) an error is
192 logged, and clients will find TLS connections fail on startup. Presumably
193 they will retry in-clear.
194 Packagers of Exim are strongly encouraged to create a server certificate
195 at installation time.
196
240c288f
JH
197HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
198 with the $config_file variable.
199
5ef5dd52
JB
200JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
201 in transport context, after the attempt, and per-recipient. The latter type
202 is per host attempted. The event data is the error message, and the errno
203 information encodes the lookup type (A vs. MX) used for the (first) host,
204 and the trailing two digits of the smtp 4xx reponse.
205
e161710d
GF
206GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
207 to write to mainlog (or rejectlog, paniclog) in the window between file
208 creation and permissions/ownership being changed. Particularly affects
209 installations where exicyclog is run as root, rather than exim user;
210 result is that the running daemon panics and dies.
211
a159f203
JH
212JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
213
7f06582c
JH
214JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
215 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
216 "pri" and "weight". Note that the previous implicit priority given by the
217 list order is no longer honoured.
218
abe1010c
JH
219JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
220 for DKIM processing.
221
f0989ec0
JH
222JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
223 by defining SUPPORT_SOCKS.
74f150bf 224
cee5f132
JH
225JH/26 Move PROXY support from Experimental to mainline, enabled for a build
226 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
227 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
228 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 229
8c5d388a
JH
230JH/27 Move Internationalisation support from Experimental to mainline, enabled
231 for a build by defining SUPPORT_I18N
232
2d8d625b
JH
233JH/28 Bug 1745: Fix redis lookups to handle (quoted) spaces embedded in parts
234 of the query string, and make ${quote_redis:} do that quoting.
235
0cbf2b82
JH
236JH/29 Move Events support from Experimental to mainline, enabled by default
237 and removable for a build by defining DISABLE_EVENT.
238

239JH/30 Updated DANE implementation code to current from Viktor Dukhovni.
240
ce325893
JH
241JH/31 Fix bug with hosts_connection_nolog and named-lists which were wrongly
242 cached by the daemon.
243
de78e2d5
JH
244JH/32 Move Redis support from Experimental to mainline, enabled for a build
245 by defining LOOKUP_REDIS. The libhiredis library is required.
246
379ba7d0
JH
247JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
248 keys are given for lookup.
249
f444c2c7
JH
250JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
251 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
252 only supported when built with TLS support. The PolarSSL SHA routines
253 are still used when the TLS library is too old for convenient support.
f444c2c7 254
a57b6200
JH
255JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
256 openssl_options), for security. OpenSSL forces this from version 1.1.0
257 server-side so match that on older versions.
258
07c73177 259JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 260 allocation for $value could be released as the expansion processing
07c73177 261 concluded, but leaving the global pointer active for it.
fa01e4f8 262
4f6ae5c3
JH
263JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
264 and to use the domains and local_parts ACL conditions.
265
1bc460a6
JH
266JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
267 incorrectly not doubled on cutthrough transmission, hence seen as a
268 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 269 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
270 via the normal store-and-forward channel. This could result in duplicates
271 received - but deduplicating mailstores were liable to retain only the
272 initial truncated version.
273
ab9152ff 274JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.
df3def24 275

276JH/40 Fix crash in queryprogram router when compiled with EXPERIMENTAL_SRS.
277
ab9152ff
JH
278JH/41 Bug 1792: Fix selection of headers to sign for DKIM: bottom-up. While
279 we're in there, support oversigning also; bug 1309.
280
af483912
JH
281JH/42 Bug 1796: Fix error logged on a malware scanner connection failure.
282
bc3c7bb7 283HS/04 Add support for keep_environment and add_environment options.
df3def24 284
13559da6
JH
285JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
286 either intentional arithmetic overflow during PRNG, or testing config-
287 induced overflows.
288
59eaad2b
JH
289JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
290 delivery resulted in actual delivery. Cancel cutthrough before DATA
291 stage.
292
f9334a28
JH
293JH/45 Fix cutthrough, when connection not opened by verify and target hard-
294 rejects a recipient: pass the reject to the originator.
295
dc8091e7
JH
296JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
297 Many were false-positives and ignorable, but it's worth fixing the
298 former class.
299
dfe7d917
JH
300JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
301 for the new environment-manipulation done at startup. Move the routines
302 from being local to tls.c to being global via the os.c file.
303
93cc2d6e
JH
304JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
305 an extract embedded as result-arg for a map, the first arg for extract
306 is unavailable so we cannot tell if this is a numbered or keyed
307 extraction. Accept either.

JH
316JH/02 The smtp transport option "multi_domain" is now expanded.
317
ad07e9ad
JH
318JH/03 The smtp transport now requests PRDR by default, if the server offers
319 it.
320
01a4a5c5 321JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 322 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
323 can be used to disable this per-host. The build option
324 EXPERIMENTAL_CERTNAMES is withdrawn.
325
cb1d7830 326JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 327 default to the word "system" to access the system default CA bundle.
cb1d7830
JH
328 For GnuTLS, only version 3.0.20 or later.
329
610ff438 330JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
331 (but not required) by default. The verification status is now logged by
332 default, for both outbound TLS and client-certificate supplying inbound
333 TLS connections
610ff438 334
f926e272
JH
335JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
336 sites use this now.
337
50dc7409
JH
338JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
339 Status Notification (bounce) messages are now MIME format per RFC 3464.
340 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
341 under the control of the dsn_advertise_hosts option, and routers may
342 have a dsn_lasthop option.
343
0f0c8159
JH
344JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
345 default, modifiable by a malware= option. The list separator for
23763898 346 the options can now be changed in the usual way. Bug 68.
4e71661f 347
1ad6489e
JH
348JH/10 The smtp_receive_timeout main option is now expanded before use.
349

351 local interface on delivery outgoing connections.
352
5032d1cf

359JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
360 Patch from Andrew Lewis.
361
fd4d8871 362JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 363 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
364 modifiers per server. Patch originally by <rommer@active.by>.
365
366JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
367 and remote servers. Remote servers can be IPv6 addresses, and
368 specify a port-range.
fd4d8871 369
23763898

798TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
799
800 When a queue runner is handling a message, Exim first routes the
801 recipient addresses, during which it prunes them based on the retry
802 hints database. After that it attempts to deliver the message to
803 any remaining recipients. It then updates the hints database using
804 the retry rules.
805
806 So if a recipient address works intermittently, it can get repeatedly
807 deferred at routing time. The retry hints record remains fresh so the
808 address never reaches the final cutoff time.
809
810 This is a fairly common occurrence when a user is bumping up against
811 their storage quota. Exim had some logic in its local delivery code
812 to deal with this. However it did not apply to per-recipient defers
813 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
814
1ddeb334
TF
815 This change adds a proper retry rule check during routing so that the
816 final cutoff time is checked against the message's age. We only do
817 this check if there is an address retry record and there is not a
818 domain retry record; this implies that previous attempts to handle
819 the address had the retry_use_local_parts option turned on. We use
820 this as an approximation for the destination being like a local
821 delivery, as in LMTP.
67bd1ab3
TF
822
823 I suspect this new check makes the old local delivery cutoff check
824 redundant, but I have not verified this so I left the code in place.

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

859 Server implementation by Todd Lyons, client by JH.
860 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
861 config variable "prdr_enable" controls whether the server
862 advertises the facility. If the client requests PRDR a new
863 acl_data_smtp_prdr ACL is called once for each recipient, after
864 the body content is received and before the acl_smtp_data ACL.
865 The client is controlled by bolth of: a hosts_try_prdr option
866 on the smtp transport, and the server advertisement.
867 Default client logging of deliveries and rejections involving
868 PRDR are flagged with the string "PRDR".

1146TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1147 lock up or crash if it happened to be inside a call to libc when it
1148 got a SIGUSR1 from exiwhat.
1149
1150 The SIGUSR1 handler appends the current process status to the process
1151 log which is later printed by exiwhat. It used to use the general
1152 purpose logging code to do this, but several functions it calls are
1153 not safe for signals.
1154
1155 The new output code in the SIGUSR1 handler is specific to the process
1156 log, and simple enough that it's easy to inspect for signal safety.
1157 Removing some special cases also simplifies the general logging code.
1158 Removing the spurious timestamps from the process log simplifies
1159 exiwhat.

TF
1161TF/04 Improved ratelimit ACL condition.
1162
1163 The /noupdate option has been deprecated in favour of /readonly which
1164 has clearer semantics. The /leaky, /strict, and /readonly update modes
1165 are mutually exclusive. The update mode is no longer included in the
1166 database key; it just determines when the database is updated. (This
1167 means that when you upgrde Exim will forget old rate measurements.)
1168
1169 Exim now checks that the per_* options are used with an update mode that
1170 makes sense for the current ACL. For example, when Exim is processing a
1171 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1172 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1173 must specify per_mail/readonly. If you omit the update mode it defaults to
1174 /leaky where that makes sense (as before) or /readonly where required.
1175
1176 The /noupdate option is now undocumented but still supported for
1177 backwards compatibility. It is equivalent to /readonly except that in
1178 ACLs where /readonly is required you may specify /leaky/noupdate or
1179 /strict/noupdate which are treated the same as /readonly.
1180
1181 A useful new feature is the /count= option. This is a generalization
1182 of the per_byte option, so that you can measure the throughput of other
1183 aggregate values. For example, the per_byte option is now equivalent
1184 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1185
1186 The per_rcpt option has been generalized using the /count= mechanism
1187 (though it's more complicated than the per_byte equivalence). When it is
1188 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1189 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1190 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1191 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1192 Note that using per_rcpt with a non-readonly update mode in more than
1193 one ACL will cause the recipients to be double-counted. (The per_mail
1194 and per_byte options don't have this problem.)
1195
1196 The handling of very low rates has changed slightly. If the computed rate
1197 is less than the event's count (usually one) then this event is the first
1198 after a long gap. In this case the rate is set to the same as this event's
1199 count, so that the first message of a spam run is counted properly.
1200
1201 The major new feature is a mechanism for counting the rate of unique
1202 events. The new per_addr option counts the number of different
1203 recipients that someone has sent messages to in the last time period. It
1204 behaves like per_rcpt if all the recipient addresses are different, but
1205 duplicate recipient addresses do not increase the measured rate. Like
1206 the /count= option this is a general mechanism, so the per_addr option
1207 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1208 example, measure the rate that a client uses different sender addresses
1209 with the options per_mail/unique=$sender_address. There are further
1210 details in the main documentation.

1760 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1761 were called 'true' and it seems that C99 defines that as a reserved
1762 keyword to be used with 'bool' variable types. That means you could
1763 not include C99-style headers which use bools without triggering

1780-----------------
1781
1782PH/01 Another patch from the Sieve maintainer.
1783
6a3bceb1
PH
1784PH/02 When an IPv6 address is converted to a string for single-key lookup
1785 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1786 dots are used instead of colons so that keys in lsearch files need not
1787 contain colons. This was done some time before quoting was made available
1788 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1789 (notated using the quote facility) so as to distinguish them from IPv4
1790 keys. This meant that lookups for IP addresses in host lists did not work
1791 for iplsearch lookups.
1792
1793 This has been fixed by arranging for IPv6 addresses to be expressed with
1794 colons if the lookup type is iplsearch. This is not incompatible, because
1795 previously such lookups could never work.
1796
1797 The situation is now rather anomolous, since one *can* have colons in
1798 ordinary lsearch keys. However, making the change in all cases is
1799 incompatible and would probably break a number of configurations.

1804MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1805 conversion specification without a maximum field width, thereby enabling
1806 a rogue spamd server to cause a buffer overflow. While nobody in their
1807 right mind would setup Exim to query an untrusted spamd server, an
1808 attacker that gains access to a server running spamd could potentially
1809 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1814MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1815 a directory entry by the name of the lookup key. Previously, if a
1816 symlink pointed to a non-existing file or a file in a directory that
1817 Exim lacked permissions to read, a lookup for a key matching that
1818 symlink would fail. Now it is enough that a matching directory entry
1819 exists, symlink or not. (Bugzilla 503.)

1896 if a client was not listed at all, or was listed with a value other than

2002PH/29 SMTP synchronization checks are implemented when a command is read -
2003 there is a check that no more input is waiting when there shouldn't be
2004 any. However, for some commands, a delay in an ACL can mean that it is
2005 some time before the response is written. In this time, more input might
2006 arrive, invalidly. So now there are extra checks after an ACL has run for
2007 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2008 pipelining has not been advertised.

PH
2082 the response to the final '.' that terminates a message, but only in the
2083 case where the client has not sent further data following the '.'
2084 (unfortunately, this is allowed). However, in many cases there won't be
2085 any further data because there won't be any more messages to send. A call
2086 to select() can be used: if it shows that the input is "ready", there is
2087 either input waiting, or the socket has been closed. An attempt to read
2088 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2089 would have sent an OK response which the client would never have see.

2099
2100PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2101 fixed by 4.65/MH/01 (is this a record?) are fixed:
2102
2103 (i) An empty string was always treated as zero by the numeric comparison
2104 operators. This behaviour has been restored.
2105
2106 (ii) It is documented that the numeric comparison operators always treat
2107 their arguments as decimal numbers. This was broken in that numbers
2108 starting with 0 were being interpreted as octal.
2109
2110 While fixing these problems I realized that there was another issue that
2111 hadn't been noticed. Values of message_size_limit (both the global option
2112 and the transport option) were treated as octal if they started with 0.
2113 The documentation was vague. These values are now always treated as
2114 decimal, and I will make that clear in the documentation.

PH
2128PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2129 child addresses, Exim now panics and dies. Previously, because the count
2130 is held in a short int, deliveries were likely to be lost. As such a
2131 large number of recipients for a single message is ridiculous
2132 (performance will be very, very poor), I have chosen to impose a limit
2133 rather than extend the field.

2139TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2140 leftover -K file (the existence of which was triggered by #402).
2141 While we were at it, introduced process PID as part of the -K

2145TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2146 processing considerably. Previous code took too long for large mails,
2147 triggering a timeout which in turn triggers #401.
2148
2149TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2150 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
2158PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2159 callout verification, Exim cached a "reject" for the entire domain. This
2160 is correct for most verifications, but it is not correct for a recipient
2161 verification with use_sender or use_postmaster set, because in that case
2162 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2163 case of MAIL FROM:<> rejection from other early rejections (e.g.
2164 rejection of HELO). When verifying a recipient using a non-null MAIL
2165 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2166 Whatever the result of the callout, the value of the domain cache is
2167 left unchanged (for any other kind of callout, getting as far as trying
2168 RCPT means that the domain itself is ok).

2202PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2204 probably the interface on which it is arriving) and not to the outgoing
2205 callout (which could be using a different interface). This has been
2206 changed to use the value of the helo_data option from the smtp transport
2207 instead - this is what is used when a message is actually being sent. If
2208 there is no remote transport (possible with a router that sets up host
2209 addresses), $smtp_active_hostname is used.

14aa5a05 2211PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2212 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2213 (a) The code assumed that strncpy() returns a negative number on buffer
2214 overflow, which isn't the case. Replaced with Exim's string_format()
2215 function.
2216 (b) There were several signed/unsigned issues. I just did the minimum
2217 hacking in of casts. There is scope for a larger refactoring.
2218 (c) The code used strcasecmp() which is not a standard C function.
2219 Replaced with Exim's strcmpic() function.
2220 (d) The code set only $1; it now sets $auth1 as well.
2221 (e) A simple test gave the error "authentication client didn't specify
2222 service in request". It would seem that Dovecot has changed its
2223 interface. Fortunately there's a specification; I followed it and
2224 changed what the client sends and it appears to be working now.

PH
2229PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2230 address A is aliased to B and C, where B exists and C does not. Without
2231 -v the output is "A verified" because verification stops after a
2232 successful redirection if more than one address is generated. However,
2233 with -v the child addresses are also verified. Exim was outputting "A
2234 failed to verify" and then showing the successful verification for C,
2235 with its parentage. It now outputs "B failed to verify", showing B's
2236 parentage before showing the successful verification of C.

2239 look up a TXT record in a specific list after matching in a combined
2240 list.
2241
322050c2
PH
2242PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2243 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2244 they consult the DNS. I had assumed they would set it the way they
2245 wanted; and indeed my experiments on Linux seem to show that in some
2246 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2247 To be on the safe side, however, I have now made the interface to
2248 host_find_byname() similar to host_find_bydns(), with an argument
2249 containing the DNS resolver options. The host_find_byname() function now
2250 sets these options at its start, just as host_find_bydns() does. The smtp
2251 transport options dns_qualify_single and dns_search_parents are passed to
2252 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2253 of host_find_byname() use the default settings of RES_DEFNAMES
2254 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2256PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2257 spool_read_header() do less string testing, by means of a preliminary
2258 switch on the second character of optional "-foo" lines. (This is
2259 overdue, caused by the large number of possibilities that now exist.
2260 Originally there were few.) While I was there, I also converted the
2261 str(n)cmp tests so they don't re-test the leading "-" and the first
2262 character, in the hope this might squeeze out yet more improvement.

PH
2264PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2265 flag allowing group syntax was set by the header_syntax check but not
2266 turned off, possible causing trouble later; (2) The flag was not being
2267 set at all for the header_verify test, causing "group"-style headers to
2268 be rejected. I have now set it in this case, and also caused header_
2269 verify to ignore an empty address taken from a group. While doing this, I
2270 came across some other cases where the code for allowing group syntax
2271 while scanning a header line wasn't quite right (mostly, not resetting
2272 the flag correctly in the right place). These bugs could have caused
2273 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2275PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2276 with the "reply" argument non-NULL. The code, however (which originally
2277 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2278 but it didn't always do it. This confused somebody who was copying the
2279 code for some other use. I have removed all the tests.

PH
2281PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2282 feature that was used to support insecure browsers during the U.S. crypto
2283 embargo. It requires special client support, and Exim is probably the
2284 only MTA that supported it -- and would never use it because real RSA is
2285 always available. This code has been removed, because it had the bad
2286 effect of slowing Exim down by computing (never used) parameters for the
2287 RSA_EXPORT functionality.

PH

2292 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2293 if the connection is using TLS or if the remote IP is the same as the
2294 local IP, and the "valid-client-cert option" if a client certificate has
2295 been verified.

2327PH/30 Exim was sometimes attempting to deliver messages that had suffered
2328 address errors (4xx response to RCPT) over the same connection as other
2329 messages routed to the same hosts. Such deliveries are always "forced",
2330 so retry times are not inspected. This resulted in far too many retries
2331 for the affected addresses. The effect occurred only when there were more
2332 hosts than the hosts_max_try setting in the smtp transport when it had
2333 the 4xx errors. Those hosts that it had tried were not added to the list
2334 of hosts for which the message was waiting, so if all were tried, there
2335 was no problem. Two fixes have been applied:
2336
2337 (i) If there are any address or message errors in an SMTP delivery, none
2338 of the hosts (tried or untried) are now added to the list of hosts
2339 for which the message is waiting, so the message should not be a
2340 candidate for sending over the same connection that was used for a
2341 successful delivery of some other message. This seems entirely
2342 reasonable: after all the message is NOT "waiting for some host".
2343 This is so "obvious" that I'm not sure why it wasn't done
2344 previously. Hope I haven't missed anything, but it can't do any
2345 harm, as the worst effect is to miss an optimization.
2346
2347 (ii) If, despite (i), such a delivery is accidentally attempted, the
2348 routing retry time is respected, so at least it doesn't keep
2349 hammering the server.

2364PH/35 The error "getsockname() failed: connection reset by peer" was being
2365 written to the panic log as well as the main log, but it isn't really
2366 panic-worthy as it just means the connection died rather early on. I have
2367 removed the panic log writing for the ECONNRESET error when getsockname()
2368 fails.
2369
48c7f9e2
PH
2370PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2371 runs only) independently of the message's sender address. This meant
2372 that, if the 4xx error was in fact related to the sender, a different
2373 message to the same recipient with a different sender could confuse
2374 things. In particualar, this can happen when sending to a greylisting
2375 server, but other circumstances could also provoke similar problems.
2376 I have changed the default so that the retry time for these errors is now
2377 based a combination of the sender and recipient addresses. This change
2378 can be overridden by setting address_retry_include_sender=false in the
2379 smtp transport.

2650 tcp-wrappers gives "deny", whereas what one would like would be some
2651 kind of temporary error. A kludge has been added to help with this.
2652 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2653 554 error is used if errno is still zero or contains ENOENT (which occurs
2654 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2739 generate an autoreply, and therefore failed to obtain an address for the
2740 autoreply, Exim could try to deliver to a non-existent relative file

2742 it logs this as a hard delivery error, but does not attempt to create a

2760 non-existent - all you got was a failure to exec. I have made two
2761 changes:
2762
2763 (a) Failures to set uid/gid, the current directory, or a process leader
2764 in a subprocess such as that created by queryprogram now generate
2765 suitable debugging ouput when -d is set.

2774PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2775 additional section of a DNS packet that returns MX or SRV records.
2776 Instead, it always explicitly searches for A/AAAA records. This avoids
2777 major problems that occur when a DNS server includes only records of one
2778 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2779 fixed another bug: if SRV records were looked up and the corresponding
2780 address records were *not* found in the additional section, the port
2781 values from the SRV records were lost.

PH
2791PH/19 When calculating a retry time, Exim used to measure the "time since
2792 failure" by looking at the "first failed" field in the retry record. Now
2793 it does not use this if it is later than than the arrival time of the
2794 message. Instead it uses the arrival time. This makes for better
2795 behaviour in cases where some deliveries succeed, thus re-setting the
2796 "first failed" field. An example is a quota failure for a huge message
2797 when small messages continue to be delivered. Without this change, the
2798 "time since failure" will always be short, possible causing more frequent
2799 delivery attempts for the huge message than are intended.

PH
2896PH/42 The content-scanning code uses fopen() to create files in which to put
2897 message data. Previously it was not paying any attention to the mode of
2898 the files. Exim runs with umask(0) because the rest of the code creates
2899 files with open(), and sets the required mode explicitly. Thus, these
2900 files were ending up world-writeable. This was not a big issue, because,
2901 being within the spool directory, they were not world-accessible. I have
2902 created a function called modefopen, which takes an additional mode
2903 argument. It sets umask(777), creates the file, chmods it to the required
2904 mode, then resets the umask. All the relevant calls to fopen() in the
2905 content scanning code have been changed to use this function.

2917 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2942
2943 (i) Exim was not creating retry information for temporary errors given
2944 for individual recipients after the DATA command when the smtp transport
2945 was used in LMTP mode. This meant that they could be retried too
2946 frequently, and not timed out correctly.
2947
2948 (ii) Exim was setting the flag that allows error details to be returned
2949 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2950 recipients that were returned after the DATA command.
2951
2952PH/53 This is related to PH/52, but is more general: for any failing address,
2953 when detailed error information was permitted to be returned to the
2954 sender, but the error was temporary, then after the final timeout, only
2955 "retry timeout exceeded" was returned. Now it returns the full error as

3026PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3027 function verify_get_ident() calls ip_connect() to connect a socket, but
3028 if the "connect()" function timed out, ip_connect() used to close the
3029 socket. However, verify_get_ident() also closes the socket later, and in
3030 between Exim writes to the log, which may get opened at this point. When
3031 the socket was closed in ip_connect(), the log could get the same file
3032 descriptor number as the socket. This naturally causes chaos. The fix is
3033 not to close the socket in ip_connect(); the socket should be closed by
3034 the function that creates it. There was only one place in the code where
3035 this was missing, in the iplookup router, which I don't think anybody now
3036 uses, but I've fixed it anyway.

3065 because their memory is reclaimed, so using them afterwards may do
3066 silly things.

3097
3098 Received: from [1.2.3.4] (helo=[1.2.3.4])
3099
3100 However, if the real host name was known, it was omitting the HELO data

3118 o adds some debug output for the result of if/elsif tests
3119 o points to the current vacation draft in the documentation
3120 and documents the missing references header update

3128PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3129 Electronic Mail") by including:
3130
3131 Auto-submitted: auto-generated
3132
3133 in the messages that it generates (bounce messages and others, such as
3134 warnings). In the case of bounce messages for non-SMTP mesages, there was
3135 also a typo: it was using "Auto_submitted" (underscore instead of
3136 hyphen). Since every message generated by Exim is necessarily in response
3137 to another message, thes have all been changed to:
3138
3139 Auto-Submitted: auto-replied
3140
3141 in accordance with these statements in the RFC:
3142
3143 The auto-replied keyword:
3144
3145 - SHOULD be used on messages sent in direct response to another
3146 message by an automatic process,
3147
3148 - MUST NOT be used on manually-generated messages,
3149
3150 - MAY be used on Delivery Status Notifications (DSNs) and Message
3151 Disposition Notifications (MDNs),
3152
3153 - MUST NOT be used on messages generated by automatic or periodic
3154 processes, except for messages which are automatic responses to
3155 other messages.

3176PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3177 extension "envelope-auth". The code is finished and in agreement with
3178 other implementations, but there is no documentation so far and in fact,
3179 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3180 not changing the active code.
3181
3182 Print executed "if" and "elsif" statements when debugging is used. This
3183 helps a great deal to understand what a filter does.
3184

3186 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3191PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3192 canonical form (as documented). However, after a host name lookup from
3193 the IP address, check_host() was doing a simple string comparison with
3194 addresses acquired from the DNS when checking that the found name did
3195 have the original IP as one of its addresses. Since any found IPv6
3196 addresses are likely to be in abbreviated form, the comparison could
3197 fail. Luckily, there already exists a function for doing the comparison
3198 by converting both addresses to binary, so now that is used instead of
3199 the text comparison.
3200
96776534
PH
3201PH/20 There was another similar case to PH/19, when a complete host name was
3202 given in a host list; looking up its IP address could give an abbreviated
3203 form, whereas the current host's name might or might not be abbreviated.
3204 The same fix has been applied.

3283PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true

3287 not happened, "verify = helo" does it there and then.
