9427e879
JH
11JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
12 than -2003 did; needs libidn2 in addition to linidn.
fd047340 13

14JH/02 The path option on a pipe transport is now expanded before use.

23Exim version 4.88
24-----------------
4c57a40e 25
9094b84b
JH
26JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
27 supports it and a size is available (ie. the sending peer gave us one).
8d042305 28
03d5892b
JH
29JH/02 The obsolete acl condition "demime" is removed (finally, after ten
30 years of being deprecated). The replacements are the ACLs
31 acl_smtp_mime and acl_not_smtp_mime.
32
4b0fe319
JH
33JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
34 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
35 or even an in-clear connection were permitted. Now, if the host lookup
36 was dnssec and dane was requested then the host is only used if the
37 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
38 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
39 if one fails this test.
40 This means that a poorly-configured remote DNS will make it incommunicado;
41 but it protects against a DNS-interception attack on it.

JH
43JH/04 Bug 1810: make continued-use of an open smtp transport connection
44 non-noisy when a race steals the message being considered.
45
23bb6982 46JH/05 If main configuration option tls_certificate is unset, generate a
f59aaaaa 47 self-signed certificate for inbound TLS connections.

0bd1b1ed 49JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 50 in rewrites and routers.

20b9a2dc
JH
52JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
53 and logged a warning sing 4.83; now they are a configuration file error.
54
05392bbc
JH
55JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
56 (lacking @domain). Apply the same qualification processing as RCPT.
57
1a6230a3
JH
58JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
59
cfab9d68
JH
60JH/10 Support ${sha256:} applied to a string (as well as the previous
61 certificate).
62
98c82a3d
JH
63JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
64 a cutthrough deliver is pending, as we always want to make a connection.
65 This also avoids re-routing the message when later placing the cutthrough
66 connection after a verify cache hit.
67 Do not update it with the verify result either.
68
69JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
70 when routing results in more than one destination address.
71
ae8386f0
JH
72JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
73 signing (which inhibits the cutthrough capability). Previously only
74 the presence of an option was tested; now an expansion evaluating as
75 empty is permissible (obviously it should depend only on data available
76 when the cutthrough connection is made).
77
0d9fa8c0
JH
78JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
79 the relevant preceding SMTP command did not note the pipelining mode.
80

JH
81JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
82 Previously they were not counted.
83
ef3a1a30
JH
84JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
85 as one having no matching records. Previously we deferred the message
86 that needed the lookup.
87
803628d5 88JH/17 Fakereject: previously logged as a norml message arrival "<="; now

92 for missing MX records. Previously it only worked for missing A records.

94JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
95

97 after the data-go-ahead and data-ack. Patch from Jason Betts.

99JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
100 even for a "none" policy. Patch from Tony Meyer.
101
1c788856
JH
102JH/22 Fix continued use of a connection for further deliveries. If a port was
103 specified by a router, it must also match for the delivery to be
104 compatible.
105
e3b1f624
JH
106JH/23 Bug 1874: fix continued use of a connection for further deliveries.
107 When one of the recipients of a message was unsuitable for the connection
108 (has no matching addresses), we lost track of needing to mark it
109 deferred. As a result mail would be lost.

JH
111JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
112
f59aaaaa 113JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
114 takes up less space and should be simpler to maintain. Merge the ACL
115 condition decode tables also, with similar effect.
d7bed771 116
d1f9fb42
JH
117JH/26 Fix problem with one_time used on a redirect router which returned the
118 parent address unchanged. A retry would see the parent address marked as
119 delivered, so not attempt the (identical) child. As a result mail would
120 be lost.
121
92b0827a
JH
122JH/27 Fix a possible security hole, wherein a process operating with the Exim
123 UID can gain a root shell. Credit to http://www.halfdog.net/ for
124 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
125 itself :(

JH
127JH/28 Enable {spool,log} filesystem space and inode checks as default.
128 Main config options check_{log,spool}_{inodes,space} are now
129 100 inodes, 10MB unless set otherwise in the configuration.

133 options.

140PP/02 Unbreak build via pkg-config with new hash support when crypto headers
141 are not in the system include path.

ad7fc6eb 143JH/31 Fix longstanding bug with aborted TLS server connection handling. Under
f59aaaaa 144 GnuTLS, when a session startup failed (eg because the client disconnected)
ad7fc6eb
JH
145 Exim did stdio operations after fclose. This was exposed by a recent
146 change which nulled out the file handle after the fclose.

JH
148JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
149 signed directly by the cert-signing cert, rather than an intermediate
150 OCSP-signing cert. This is the model used by LetsEncrypt.

JH
170JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
171 and 3.4.4 - once the server is enabled to respond to an OCSP request
172 it does even when not requested, resulting in a stapling non-aware
173 client dropping the TLS connection.

175TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
176 support variable-length bit vectors. No functional change.
177
ac881e27
TF
178TF/02 Improve the consistency of logging incoming and outgoing interfaces.
179 The I= interface field on outgoing lines is now after the H= remote
180 host field, same as incoming lines. There is a separate
181 outgoing_interface log selector which allows you to disable the
182 outgoing I= field.
183
c8899c20
JH
184JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
185 If not running log_selector +smtp_connection the mainlog would be held
186 open indefinitely after a "too many connections" event, including to a
187 deleted file after a log rotate. Leave the per net connection logging
188 leaving it open for efficiency as that will be quickly detected by the
189 check on the next write.

HSHR
191HS/01 Bug 1671: Fix post transport crash.
192 Processing the wait-<transport> messages could crash the delivery
193 process if the message IDs didn't exist for some reason. When
194 using 'split_spool_directory=yes' the construction of the spool
195 file name failed already, exposing the same netto behaviour.
196

197JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
198 mime_regex ACL conditions.

JH
200JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
201 to DSN fail messages (bounces): remote IP, remote greeting, remote response
202 to HELO, local diagnostic string.
203
805bb5c3
JH
204JH/05 Downgrade message for a TLS-certificate-based authentication fail from
205 log line to debug. Even when configured with a tls authenticator many
206 client connections are expected to not authenticate in this way, so
207 an authenticate fail is not an error.
208
56c2a7be
HSHR
209HS/02 Add the Exim version string to the process info. This way exiwhat
210 gives some more detail about the running daemon.
211

JH
212JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
213 matter for fast-change records such as DNSBLs.
214
6f6dedcc
JH
215JH/07 Bug 1678: Always record an interface option value, if set, as part of a
216 retry record, even if constant. There may be multiple transports with
217 different interface settings and the retry behaviour needs to be kept
218 distinct.
219
0f557e90
JH
220JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
221
222JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.

225
41e93589
JH
226JH/11 Bug 830: use same host for all RCPTS of a message, even under
227 hosts_randomize. This matters a lot when combined with mua_wrapper.
228
98b98887 229JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
230 ${quote_pgsql:<string>} operator.

234JH/14 Change header file name for freeradius-client. Relevant if compiling
235 with Radius support; from the Gentoo tree and checked under Fedora.

238
6ff55e50
JH
239JH/16 Bug 1714: Permit an empty string as expansion result for transport
240 option transport_filter, meaning no filtering.

242JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
243
23f3dc67
JH
244JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
245 defaults to "*" (all hosts). The variable is now available when not built
246 with TLS, default unset, mainly to enable keeping the testuite sane.
247 If a server certificate is not supplied (via tls_certificate) an error is
248 logged, and clients will find TLS connections fail on startup. Presumably
249 they will retry in-clear.
250 Packagers of Exim are strongly encouraged to create a server certificate
251 at installation time.
252
240c288f
JH
253HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
254 with the $config_file variable.
255
5ef5dd52
JB
256JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
257 in transport context, after the attempt, and per-recipient. The latter type
258 is per host attempted. The event data is the error message, and the errno
259 information encodes the lookup type (A vs. MX) used for the (first) host,
260 and the trailing two digits of the smtp 4xx reponse.
261
e161710d
GF
262GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
263 to write to mainlog (or rejectlog, paniclog) in the window between file
264 creation and permissions/ownership being changed. Particularly affects
265 installations where exicyclog is run as root, rather than exim user;
266 result is that the running daemon panics and dies.

JH
270JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
271 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
272 "pri" and "weight". Note that the previous implicit priority given by the
273 list order is no longer honoured.

281JH/26 Move PROXY support from Experimental to mainline, enabled for a build
282 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989

283 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
284 variables are renamed to proxy_{local,external}_{address,port}.

303JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
304 keys are given for lookup.

f444c2c7
JH
306JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
307 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
308 only supported when built with TLS support. The PolarSSL SHA routines
309 are still used when the TLS library is too old for convenient support.
f444c2c7 310
a57b6200
JH
311JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
312 openssl_options), for security. OpenSSL forces this from version 1.1.0
313 server-side so match that on older versions.
314
07c73177 315JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 316 allocation for $value could be released as the expansion processing
07c73177 317 concluded, but leaving the global pointer active for it.
fa01e4f8 318

JH
319JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
320 and to use the domains and local_parts ACL conditions.
321
1bc460a6
JH
322JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
323 incorrectly not doubled on cutthrough transmission, hence seen as a
324 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 325 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
326 via the normal store-and-forward channel. This could result in duplicates
327 received - but deduplicating mailstores were liable to retain only the
328 initial truncated version.

341JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
342 either intentional arithmetic overflow during PRNG, or testing config-

345JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
346 delivery resulted in actual delivery. Cancel cutthrough before DATA
347 stage.

349JH/45 Fix cutthrough, when connection not opened by verify and target hard-
350 rejects a recipient: pass the reject to the originator.
351
dc8091e7
JH
352JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
353 Many were false-positives and ignorable, but it's worth fixing the
354 former class.
355
dfe7d917
JH
356JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
357 for the new environment-manipulation done at startup. Move the routines
358 from being local to tls.c to being global via the os.c file.
359

JH
360JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
361 an extract embedded as result-arg for a map, the first arg for extract
362 is unavailable so we cannot tell if this is a numbered or keyed
363 extraction. Accept either.

375 it.
376
01a4a5c5 377JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 378 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
379 can be used to disable this per-host. The build option
380 EXPERIMENTAL_CERTNAMES is withdrawn.
381
cb1d7830 382JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 383 default to the word "system" to access the system default CA bundle.

855TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
856
857 When a queue runner is handling a message, Exim first routes the
858 recipient addresses, during which it prunes them based on the retry
859 hints database. After that it attempts to deliver the message to
860 any remaining recipients. It then updates the hints database using
861 the retry rules.
862
863 So if a recipient address works intermittently, it can get repeatedly
864 deferred at routing time. The retry hints record remains fresh so the
865 address never reaches the final cutoff time.
866
867 This is a fairly common occurrence when a user is bumping up against
868 their storage quota. Exim had some logic in its local delivery code
869 to deal with this. However it did not apply to per-recipient defers
870 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
871
1ddeb334
TF
872 This change adds a proper retry rule check during routing so that the
873 final cutoff time is checked against the message's age. We only do
874 this check if there is an address retry record and there is not a
875 domain retry record; this implies that previous attempts to handle
876 the address had the retry_use_local_parts option turned on. We use
877 this as an approximation for the destination being like a local
878 delivery, as in LMTP.
67bd1ab3
TF
879
880 I suspect this new check makes the old local delivery cutoff check
881 redundant, but I have not verified this so I left the code in place.

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

916 Server implementation by Todd Lyons, client by JH.
917 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
918 config variable "prdr_enable" controls whether the server
919 advertises the facility. If the client requests PRDR a new
920 acl_data_smtp_prdr ACL is called once for each recipient, after
921 the body content is received and before the acl_smtp_data ACL.
922 The client is controlled by bolth of: a hosts_try_prdr option
923 on the smtp transport, and the server advertisement.
924 Default client logging of deliveries and rejections involving
925 PRDR are flagged with the string "PRDR".

1203TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1204 lock up or crash if it happened to be inside a call to libc when it
1205 got a SIGUSR1 from exiwhat.
1206
1207 The SIGUSR1 handler appends the current process status to the process
1208 log which is later printed by exiwhat. It used to use the general
1209 purpose logging code to do this, but several functions it calls are
1210 not safe for signals.
1211
1212 The new output code in the SIGUSR1 handler is specific to the process
1213 log, and simple enough that it's easy to inspect for signal safety.
1214 Removing some special cases also simplifies the general logging code.
1215 Removing the spurious timestamps from the process log simplifies
1216 exiwhat.

1218TF/04 Improved ratelimit ACL condition.
1219
1220 The /noupdate option has been deprecated in favour of /readonly which
1221 has clearer semantics. The /leaky, /strict, and /readonly update modes
1222 are mutually exclusive. The update mode is no longer included in the
1223 database key; it just determines when the database is updated. (This
1224 means that when you upgrde Exim will forget old rate measurements.)
1225
1226 Exim now checks that the per_* options are used with an update mode that
1227 makes sense for the current ACL. For example, when Exim is processing a
1228 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1229 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1230 must specify per_mail/readonly. If you omit the update mode it defaults to
1231 /leaky where that makes sense (as before) or /readonly where required.
1232
1233 The /noupdate option is now undocumented but still supported for
1234 backwards compatibility. It is equivalent to /readonly except that in
1235 ACLs where /readonly is required you may specify /leaky/noupdate or
1236 /strict/noupdate which are treated the same as /readonly.
1237
1238 A useful new feature is the /count= option. This is a generalization
1239 of the per_byte option, so that you can measure the throughput of other
1240 aggregate values. For example, the per_byte option is now equivalent
1241 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1242
1243 The per_rcpt option has been generalized using the /count= mechanism
1244 (though it's more complicated than the per_byte equivalence). When it is
1245 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1246 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1247 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1248 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1249 Note that using per_rcpt with a non-readonly update mode in more than
1250 one ACL will cause the recipients to be double-counted. (The per_mail
1251 and per_byte options don't have this problem.)
1252
1253 The handling of very low rates has changed slightly. If the computed rate
1254 is less than the event's count (usually one) then this event is the first
1255 after a long gap. In this case the rate is set to the same as this event's
1256 count, so that the first message of a spam run is counted properly.
1257
1258 The major new feature is a mechanism for counting the rate of unique
1259 events. The new per_addr option counts the number of different
1260 recipients that someone has sent messages to in the last time period. It
1261 behaves like per_rcpt if all the recipient addresses are different, but
1262 duplicate recipient addresses do not increase the measured rate. Like
1263 the /count= option this is a general mechanism, so the per_addr option
1264 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1265 example, measure the rate that a client uses different sender addresses
1266 with the options per_mail/unique=$sender_address. There are further
1267 details in the main documentation.

1839PH/01 Another patch from the Sieve maintainer.
1840
6a3bceb1
PH
1841PH/02 When an IPv6 address is converted to a string for single-key lookup
1842 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1843 dots are used instead of colons so that keys in lsearch files need not
1844 contain colons. This was done some time before quoting was made available
1845 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1846 (notated using the quote facility) so as to distinguish them from IPv4
1847 keys. This meant that lookups for IP addresses in host lists did not work
1848 for iplsearch lookups.
1849
1850 This has been fixed by arranging for IPv6 addresses to be expressed with
1851 colons if the lookup type is iplsearch. This is not incompatible, because
1852 previously such lookups could never work.
1853
1854 The situation is now rather anomolous, since one *can* have colons in
1855 ordinary lsearch keys. However, making the change in all cases is
1856 incompatible and would probably break a number of configurations.

MH
1861MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1862 conversion specification without a maximum field width, thereby enabling
1863 a rogue spamd server to cause a buffer overflow. While nobody in their
1864 right mind would setup Exim to query an untrusted spamd server, an
1865 attacker that gains access to a server running spamd could potentially
1866 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1871MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1872 a directory entry by the name of the lookup key. Previously, if a
1873 symlink pointed to a non-existing file or a file in a directory that
1874 Exim lacked permissions to read, a lookup for a key matching that
1875 symlink would fail. Now it is enough that a matching directory entry
1876 exists, symlink or not. (Bugzilla 503.)

1942MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
1943 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
1944 Jan Srzednicki.

PH
1946PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
1947 issue a MAIL command.

PH
1949PH/02 In an ACL statement such as
1950
1951 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1952
1953 if a client was not listed at all, or was listed with a value other than
1954 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1955 the condition was not true (as it should be), so access was not denied.
1956 The bug was that the ! inversion was incorrectly passed on to the second
1957 item. This has been fixed.
1958
1959PH/03 Added additional dnslists conditions == and =& which are different from
1960 = and & when the dns lookup returns more than one IP address.
1961
83da1223
PH
1962PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
1963 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
1964
54fc8428
PH
1965PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
1966 FSYNC, which compiles an option called disable_fsync that allows for
1967 bypassing fsync(). The documentation is heavily laced with warnings.

PH
1971PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
1972 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
1973 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
1974 including adding "make clean"; (3) Added -fPIC when compiling the test
1975 dynamically loaded module, to get rid of a warning.
1976
0e8a9471
MH
1977MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
1978 message fails, move_frozen_messages = true and ignore_bounce_errors_after
1979 = 0s. The bug is otherwise harmless.
1980
f0872424
PH
1981PH/07 There was a bug in the dovecot authenticator such that the value of
1982 $auth1 could be overwritten, and so not correctly preserved, after a
1983 successful authentication. This usually meant that the value preserved by
1984 the server_setid option was incorrect.
1985
b01dd148

1986PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.

PH
1990PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1991 run for batched SMTP input. It is now run at the start of every message
1992 in the batch. While fixing this I discovered that the process information
1993 (output by running exiwhat) was not always getting set for -bs and -bS
1994 input. This is fixed, and it now also says "batched" for BSMTP.

1999 patch, slightly modified), and move the expansion of helo_data till after
2000 the connection is made in the smtp transport (so it can use these
2001 values).

2016PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
2017 was true (the default) a successful delivery failed to delete the retry
2018 item, thus causing premature timeout of the address. The bug is now

PH
2045PH/27 When a message times out after an over-quota error from an Exim-imposed
2046 quota, the bounce message says "mailbox is full". This message was not
2047 being given when it was a system quota that was exceeded. It now should
2048 be the same.

0e20aff9
MH
2050MH/03 Made $recipients available in local_scan(). local_scan() already has
2051 better access to the recipient list through recipients_list[], but
2052 $recipients can be useful in postmaster-provided expansion strings.
2053
ca86f471
PH
2054PH/28 The $smtp_command and $smtp_command_argument variables were not correct
2055 in the case of a MAIL command with additional options following the
2056 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
2057 were accidentally chopped off.
2058
a14e5636
PH
2059PH/29 SMTP synchronization checks are implemented when a command is read -
2060 there is a check that no more input is waiting when there shouldn't be
2061 any. However, for some commands, a delay in an ACL can mean that it is
2062 some time before the response is written. In this time, more input might
2063 arrive, invalidly. So now there are extra checks after an ACL has run for
2064 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2065 pipelining has not been advertised.
2066

57c2c631
PH
2073PH/32 Change the Dovecot authenticator to use read() and write() on the socket
2074 instead of the C I/O that was originally supplied, because problems were
2075 reported on Solaris.
2076
58c01c94
PH
2077PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
2078 Exim which did not show up earlier: it was assuming that a call to
2079 SSL_CTX_set_info_callback() might give an error value. In fact, there is
2080 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2081 was a macro that became an assignment, so it seemed to work. This has
2082 changed to a proper function call with a void return, hence the compile
2083 error. Exim's code has been fixed.

2094 "Completed" line in the log. When some messages of this type were
2095 selected by exigrep, they were listed as "not completed". Others were

2097 criteria to be more general.

PH
2099PH/38 The host_find_failed option in the manualroute router can now be set
2100 to "ignore", to completely ignore a host whose IP address cannot be
2101 found. If all hosts are ignored, the behaviour is controlled by the new
2102 host_all_ignored option.
2103
cd9868ec
PH
2104PH/39 In a list of hosts for manualroute, if one item (either because of multi-
2105 homing or because of multiple MX records with /mx) generated more than
2106 one IP address, and the following item turned out to be the local host,
2107 all the secondary addresses of the first item were incorrectly removed
2108 from the list, along with the local host and any following hosts (which
2109 is what is supposed to happen).

ebeaf996
PH
2111PH/40 When Exim receives a message, it writes the login name, uid, and gid of
2112 whoever called Exim into the -H file. In the case of the daemon it was
2113 behaving confusingly. When first started, it used values for whoever
2114 started the daemon, but after a SIGHUP it used the Exim user (because it
2115 calls itself on a restart). I have changed the code so that it now always
2116 uses the Exim user.
2117
2679d413
PH
2118PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
2119 message are rejected with the same error (e.g. no authentication or bad
2120 sender address), and a DATA command is nevertheless sent (as can happen
2121 with PIPELINING or a stupid MUA), the error message that was given to the
2122 RCPT commands is included in the rejection of the DATA command. This is
2123 intended to be helpful for MUAs that show only the final error to their
2124 users.

2137
58eb016e 2138PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
2139 the response to the final '.' that terminates a message, but only in the
2140 case where the client has not sent further data following the '.'
2141 (unfortunately, this is allowed). However, in many cases there won't be
2142 any further data because there won't be any more messages to send. A call
2143 to select() can be used: if it shows that the input is "ready", there is
2144 either input waiting, or the socket has been closed. An attempt to read
2145 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2146 would have sent an OK response which the client would never have see.
563b63fa

2147 This could lead to message repetition. This fix should cure that, at

2154Exim version 4.66
2155-----------------
2156
2157PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2158 fixed by 4.65/MH/01 (is this a record?) are fixed:
2159
2160 (i) An empty string was always treated as zero by the numeric comparison
2161 operators. This behaviour has been restored.
2162
2163 (ii) It is documented that the numeric comparison operators always treat
2164 their arguments as decimal numbers. This was broken in that numbers
2165 starting with 0 were being interpreted as octal.
2166
2167 While fixing these problems I realized that there was another issue that
2168 hadn't been noticed. Values of message_size_limit (both the global option
2169 and the transport option) were treated as octal if they started with 0.
2170 The documentation was vague. These values are now always treated as
2171 decimal, and I will make that clear in the documentation.

MH

4362ff0d
PH
2185PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2186 child addresses, Exim now panics and dies. Previously, because the count
2187 is held in a short int, deliveries were likely to be lost. As such a
2188 large number of recipients for a single message is ridiculous
2189 (performance will be very, very poor), I have chosen to impose a limit
2190 rather than extend the field.

TK
2196TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2197 leftover -K file (the existence of which was triggered by #402).
2198 While we were at it, introduced process PID as part of the -K
2199 filename. This should rule out race conditions when creating
2200 these files.
2201
2202TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2203 processing considerably. Previous code took too long for large mails,
2204 triggering a timeout which in turn triggers #401.
2205
2206TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2207 in the DK code in transports.c. sendfile() is not really portable,
2208 hence the _LINUX specificness.

2209
2210TF/01 In the add_headers option to the mail command in an Exim filter,

2213 in the field name.
2214
2b1c6e3a
PH
2215PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2216 callout verification, Exim cached a "reject" for the entire domain. This
2217 is correct for most verifications, but it is not correct for a recipient
2218 verification with use_sender or use_postmaster set, because in that case
2219 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2220 case of MAIL FROM:<> rejection from other early rejections (e.g.
2221 rejection of HELO). When verifying a recipient using a non-null MAIL
2222 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2223 Whatever the result of the callout, the value of the domain cache is
2224 left unchanged (for any other kind of callout, getting as far as trying
2225 RCPT means that the domain itself is ok).

2259PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2260 hostname. This is wrong, because it relates to the incoming message (and
2261 probably the interface on which it is arriving) and not to the outgoing
2262 callout (which could be using a different interface). This has been
2263 changed to use the value of the helo_data option from the smtp transport
2264 instead - this is what is used when a message is actually being sent. If
2265 there is no remote transport (possible with a router that sets up host
2266 addresses), $smtp_active_hostname is used.
6ea85e9a 2267
14aa5a05 2268PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2269 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2270 (a) The code assumed that strncpy() returns a negative number on buffer
2271 overflow, which isn't the case. Replaced with Exim's string_format()
2272 function.
2273 (b) There were several signed/unsigned issues. I just did the minimum
2274 hacking in of casts. There is scope for a larger refactoring.
2275 (c) The code used strcasecmp() which is not a standard C function.
2276 Replaced with Exim's strcmpic() function.
2277 (d) The code set only $1; it now sets $auth1 as well.
2278 (e) A simple test gave the error "authentication client didn't specify
2279 service in request". It would seem that Dovecot has changed its
2280 interface. Fortunately there's a specification; I followed it and
2281 changed what the client sends and it appears to be working now.

PH
2286PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2287 address A is aliased to B and C, where B exists and C does not. Without
2288 -v the output is "A verified" because verification stops after a
2289 successful redirection if more than one address is generated. However,
2290 with -v the child addresses are also verified. Exim was outputting "A
2291 failed to verify" and then showing the successful verification for C,
2292 with its parentage. It now outputs "B failed to verify", showing B's
2293 parentage before showing the successful verification of C.

2295PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2296 look up a TXT record in a specific list after matching in a combined
2297 list.
2298
322050c2
PH
2299PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2300 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2301 they consult the DNS. I had assumed they would set it the way they
2302 wanted; and indeed my experiments on Linux seem to show that in some
2303 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2304 To be on the safe side, however, I have now made the interface to
2305 host_find_byname() similar to host_find_bydns(), with an argument
2306 containing the DNS resolver options. The host_find_byname() function now
2307 sets these options at its start, just as host_find_bydns() does. The smtp
2308 transport options dns_qualify_single and dns_search_parents are passed to
2309 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2310 of host_find_byname() use the default settings of RES_DEFNAMES
2311 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2313PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2314 spool_read_header() do less string testing, by means of a preliminary
2315 switch on the second character of optional "-foo" lines. (This is
2316 overdue, caused by the large number of possibilities that now exist.
2317 Originally there were few.) While I was there, I also converted the
2318 str(n)cmp tests so they don't re-test the leading "-" and the first
2319 character, in the hope this might squeeze out yet more improvement.

2323 turned off, possible causing trouble later; (2) The flag was not being
2324 set at all for the header_verify test, causing "group"-style headers to
2325 be rejected. I have now set it in this case, and also caused header_
2326 verify to ignore an empty address taken from a group. While doing this, I
2327 came across some other cases where the code for allowing group syntax
2328 while scanning a header line wasn't quite right (mostly, not resetting
2329 the flag correctly in the right place). These bugs could have caused
2330 trouble for malformed header lines. I hope it is now all correct.

2332PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2333 with the "reply" argument non-NULL. The code, however (which originally
2334 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2335 but it didn't always do it. This confused somebody who was copying the
2336 code for some other use. I have removed all the tests.

PH
2338PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2339 feature that was used to support insecure browsers during the U.S. crypto
2340 embargo. It requires special client support, and Exim is probably the
2341 only MTA that supported it -- and would never use it because real RSA is
2342 always available. This code has been removed, because it had the bad
2343 effect of slowing Exim down by computing (never used) parameters for the
2344 RSA_EXPORT functionality.

2346PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2347 authenticator to fail if there's a tab character in the incoming data

2349 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2350 if the connection is using TLS or if the remote IP is the same as the
2351 local IP, and the "valid-client-cert option" if a client certificate has
2352 been verified.

2383
2384PH/30 Exim was sometimes attempting to deliver messages that had suffered
2385 address errors (4xx response to RCPT) over the same connection as other
2386 messages routed to the same hosts. Such deliveries are always "forced",
2387 so retry times are not inspected. This resulted in far too many retries
2388 for the affected addresses. The effect occurred only when there were more
2389 hosts than the hosts_max_try setting in the smtp transport when it had
2390 the 4xx errors. Those hosts that it had tried were not added to the list
2391 of hosts for which the message was waiting, so if all were tried, there
2392 was no problem. Two fixes have been applied:
2393
2394 (i) If there are any address or message errors in an SMTP delivery, none
2395 of the hosts (tried or untried) are now added to the list of hosts
2396 for which the message is waiting, so the message should not be a
2397 candidate for sending over the same connection that was used for a
2398 successful delivery of some other message. This seems entirely
2399 reasonable: after all the message is NOT "waiting for some host".
2400 This is so "obvious" that I'm not sure why it wasn't done
2401 previously. Hope I haven't missed anything, but it can't do any
2402 harm, as the worst effect is to miss an optimization.
2403
2404 (ii) If, despite (i), such a delivery is accidentally attempted, the
2405 routing retry time is respected, so at least it doesn't keep
2406 hammering the server.

2421PH/35 The error "getsockname() failed: connection reset by peer" was being
2422 written to the panic log as well as the main log, but it isn't really
2423 panic-worthy as it just means the connection died rather early on. I have
2424 removed the panic log writing for the ECONNRESET error when getsockname()
2425 fails.
2426
48c7f9e2
PH
2427PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2428 runs only) independently of the message's sender address. This meant
2429 that, if the 4xx error was in fact related to the sender, a different
2430 message to the same recipient with a different sender could confuse
2431 things. In particualar, this can happen when sending to a greylisting
2432 server, but other circumstances could also provoke similar problems.
2433 I have changed the default so that the retry time for these errors is now
2434 based a combination of the sender and recipient addresses. This change
2435 can be overridden by setting address_retry_include_sender=false in the
2436 smtp transport.

2737 used only to exclude .Trash (or whatever) when the size of the mailbox

2748PH/01 The code for finding all the local interface addresses on a FreeBSD
2749 system running IPv6 was broken. This may well have applied to all BSD
2750 systems, as well as to others that have similar system calls. The broken
2751 code found IPv4 interfaces correctly, but gave incorrect values for the
2752 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2753 that it would not match correctly against @[] and not recognize the IPv6
2754 addresses as local.

2834 major problems that occur when a DNS server includes only records of one
2835 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2836 fixed another bug: if SRV records were looked up and the corresponding
2837 address records were *not* found in the additional section, the port
2838 values from the SRV records were lost.

PH
2848PH/19 When calculating a retry time, Exim used to measure the "time since
2849 failure" by looking at the "first failed" field in the retry record. Now
2850 it does not use this if it is later than than the arrival time of the
2851 message. Instead it uses the arrival time. This makes for better
2852 behaviour in cases where some deliveries succeed, thus re-setting the
2853 "first failed" field. An example is a quota failure for a huge message
2854 when small messages continue to be delivered. Without this change, the
2855 "time since failure" will always be short, possible causing more frequent
2856 delivery attempts for the huge message than are intended.

2953PH/42 The content-scanning code uses fopen() to create files in which to put
2954 message data. Previously it was not paying any attention to the mode of
2955 the files. Exim runs with umask(0) because the rest of the code creates
2956 files with open(), and sets the required mode explicitly. Thus, these
2957 files were ending up world-writeable. This was not a big issue, because,
2958 being within the spool directory, they were not world-accessible. I have
2959 created a function called modefopen, which takes an additional mode
2960 argument. It sets umask(777), creates the file, chmods it to the required
2961 mode, then resets the umask. All the relevant calls to fopen() in the

3002 was used in LMTP mode. This meant that they could be retried too
3003 frequently, and not timed out correctly.
3004
3005 (ii) Exim was setting the flag that allows error details to be returned
3006 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3007 recipients that were returned after the DATA command.
3008
3009PH/53 This is related to PH/52, but is more general: for any failing address,
3010 when detailed error information was permitted to be returned to the

3084 function verify_get_ident() calls ip_connect() to connect a socket, but
3085 if the "connect()" function timed out, ip_connect() used to close the
3086 socket. However, verify_get_ident() also closes the socket later, and in
3087 between Exim writes to the log, which may get opened at this point. When
3088 the socket was closed in ip_connect(), the log could get the same file
3089 descriptor number as the socket. This naturally causes chaos. The fix is
3090 not to close the socket in ip_connect(); the socket should be closed by
3091 the function that creates it. There was only one place in the code where
3092 this was missing, in the iplookup router, which I don't think anybody now
3093 uses, but I've fixed it anyway.

3095PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as
3096 well as to direct DNS lookups. Otherwise the handling of names in host
3097 lists is inconsistent and therefore confusing.

PH
3103PH/01 Two changes to the default runtime configuration:
3104
3105 (1) Move the checks for relay_from_hosts and authenticated clients from
3106 after to before the (commented out) DNS black list checks.
3107
3108 (2) Add control=submission to the relay_from_hosts and authenticated
3109 clients checks, on the grounds that messages accepted by these
3110 statements are most likely to be submissions.

PH
3112PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3113
3114 (1) Generate an error if the third argument for the ${prvs expansion is
3115 not a single digit.
3116
3117 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3118 string.
3119
3120 (3) Reset the variables that are obtained from the first argument of
3121 ${prvscheck and used in the second argument before leaving the code,
3122 because their memory is reclaimed, so using them afterwards may do
3123 silly things.
3124
3125 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3126 one (it's much easier than Tom thought :-).
3127
3128 (5) Because of (4), we can now allow for the use of $prvscheck_result
3129 inside the third argument.

PH
3138PH/05 When a filter generated an autoreply, the entire To: header line was
3139 quoted in the delivery log line, like this:
3140
3141 => >A.N.Other <ano@some.domain> <original@ddress> ...
3142
3143 This has been changed so that it extracts the operative address. There
3144 may be more than one such address. If so, they are comma-separated, like
3145 this:
3146
3147 => >ano@some.domain,ona@other.domain <original@ddress> ...
3148
82c19f95
PH
3149PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3150 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3151 not being looked up in the rDNS to get a host name, Exim was showing the
3152 IP address twice in Received: lines, even though the IP addresses were
3153 identical. For example:
3154
3155 Received: from [1.2.3.4] (helo=[1.2.3.4])
3156
3157 However, if the real host name was known, it was omitting the HELO data
3158 if it matched the actual IP address. This has been tidied up so that it
3159 doesn't show the same IP address twice.

PH
3161PH/07 When both +timestamp and +memory debugging was on, the value given by
3162 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3163 called by the debug printing, thereby overwriting the timestamp buffer.
3164 Debugging no longer uses the tod_stamp() function when +timestamp is set.

PH
3166PH/08 When the original message was included in an autoreply transport, it
3167 always said "this is a copy of the message, including all the headers",
3168 even if body_only or headers_only was set. It now gives an appropriate
3169 message.

3171PH/09 Applied a patch from the Sieve maintainer which:
3172
3173 o fixes some comments
3174 o adds the (disabled) notify extension core
3175 o adds some debug output for the result of if/elsif tests
3176 o points to the current vacation draft in the documentation
3177 and documents the missing references header update
3178
3179 and most important:
3180
3181 o fixes a bug in processing the envelope test (when testing
3182 multiple envelope elements, the last element determinted the
3183 result)

PH
3185PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3186 Electronic Mail") by including:
3187
3188 Auto-submitted: auto-generated
3189
3190 in the messages that it generates (bounce messages and others, such as
3191 warnings). In the case of bounce messages for non-SMTP mesages, there was
3192 also a typo: it was using "Auto_submitted" (underscore instead of
3193 hyphen). Since every message generated by Exim is necessarily in response
3194 to another message, thes have all been changed to:
3195
3196 Auto-Submitted: auto-replied
3197
3198 in accordance with these statements in the RFC:
3199
3200 The auto-replied keyword:
3201
3202 - SHOULD be used on messages sent in direct response to another
3203 message by an automatic process,
3204
3205 - MUST NOT be used on manually-generated messages,
3206
3207 - MAY be used on Delivery Status Notifications (DSNs) and Message
3208 Disposition Notifications (MDNs),
3209
3210 - MUST NOT be used on messages generated by automatic or periodic
3211 processes, except for messages which are automatic responses to
3212 other messages.

3223PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length

3227PH/15 If the first argument of "${if match_address" was not empty, but did not

3233PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3234 extension "envelope-auth". The code is finished and in agreement with
3235 other implementations, but there is no documentation so far and in fact,
3236 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3237 not changing the active code.
3238
3239 Print executed "if" and "elsif" statements when debugging is used. This
3240 helps a great deal to understand what a filter does.
3241
3242 Document more things not specified clearly in RFC3028. I had all this
3243 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3248PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3249 canonical form (as documented). However, after a host name lookup from
3250 the IP address, check_host() was doing a simple string comparison with
3251 addresses acquired from the DNS when checking that the found name did
3252 have the original IP as one of its addresses. Since any found IPv6
3253 addresses are likely to be in abbreviated form, the comparison could
3254 fail. Luckily, there already exists a function for doing the comparison
3255 by converting both addresses to binary, so now that is used instead of
3256 the text comparison.
3257
96776534
PH
3258PH/20 There was another similar case to PH/19, when a complete host name was
3259 given in a host list; looking up its IP address could give an abbreviated
3260 form, whereas the current host's name might or might not be abbreviated.
3261 The same fix has been applied.

3279 non-personal, in accordance with RFC 3834. (Previously it treated
3280 anything starting "auto-" as non-personal.)

3282TF/01 The control=submission/name=... option had a problem with syntax
3283 errors if the name included a slash character. The /name= option
