JH
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.

23JH/04 Bug 1810: make continued-use of an open smtp transport connection
24 non-noisy when a race steals the message being considered.

JH
26JH/05 If main configuration option tls_certificate is unset, generate a
27 selfsigned certificate for inbound TLS connections.

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

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

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 :(

108Exim version 4.87
109-----------------
82d14d6a
JH
110JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
111 and 3.4.4 - once the server is enabled to respond to an OCSP request
112 it does even when not requested, resulting in a stapling non-aware
113 client dropping the TLS connection.

TF
115TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
116 support variable-length bit vectors. No functional change.
117
ac881e27
TF
118TF/02 Improve the consistency of logging incoming and outgoing interfaces.
119 The I= interface field on outgoing lines is now after the H= remote
120 host field, same as incoming lines. There is a separate
121 outgoing_interface log selector which allows you to disable the
122 outgoing I= field.
123
c8899c20
JH
124JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
125 If not running log_selector +smtp_connection the mainlog would be held
126 open indefinitely after a "too many connections" event, including to a
127 deleted file after a log rotate. Leave the per net connection logging
128 leaving it open for efficiency as that will be quickly detected by the
129 check on the next write.
130

HSHR
131HS/01 Bug 1671: Fix post transport crash.
132 Processing the wait-<transport> messages could crash the delivery
133 process if the message IDs didn't exist for some reason. When
134 using 'split_spool_directory=yes' the construction of the spool
135 file name failed already, exposing the same netto behaviour.
136

JH
137JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
138 mime_regex ACL conditions.
139
895fbaf2
JH
140JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
141 to DSN fail messages (bounces): remote IP, remote greeting, remote response
142 to HELO, local diagnostic string.
143
805bb5c3
JH
144JH/05 Downgrade message for a TLS-certificate-based authentication fail from
145 log line to debug. Even when configured with a tls authenticator many
146 client connections are expected to not authenticate in this way, so
147 an authenticate fail is not an error.
148
56c2a7be
HSHR
149HS/02 Add the Exim version string to the process info. This way exiwhat
150 gives some more detail about the running daemon.
151
14b3c5bc
JH
152JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
153 matter for fast-change records such as DNSBLs.
154
6f6dedcc
JH
155JH/07 Bug 1678: Always record an interface option value, if set, as part of a
156 retry record, even if constant. There may be multiple transports with
157 different interface settings and the retry behaviour needs to be kept
158 distinct.
159

JH
160JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
161
162JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
163

164JH/10 Bug 840: fix log_defer_output option of pipe transport
165
41e93589
JH
166JH/11 Bug 830: use same host for all RCPTS of a message, even under
167 hosts_randomize. This matters a lot when combined with mua_wrapper.
168
98b98887 169JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0

174JH/14 Change header file name for freeradius-client. Relevant if compiling
175 with Radius support; from the Gentoo tree and checked under Fedora.
176
177JH/15 Bug 1712: Introduce $prdr_requested flag variable
178
6ff55e50
JH
179JH/16 Bug 1714: Permit an empty string as expansion result for transport
180 option transport_filter, meaning no filtering.

3b957582
JB
182JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
183
23f3dc67
JH
184JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
185 defaults to "*" (all hosts). The variable is now available when not built
186 with TLS, default unset, mainly to enable keeping the testuite sane.
187 If a server certificate is not supplied (via tls_certificate) an error is
188 logged, and clients will find TLS connections fail on startup. Presumably
189 they will retry in-clear.
190 Packagers of Exim are strongly encouraged to create a server certificate
191 at installation time.
192
240c288f
JH
193HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
194 with the $config_file variable.
195
5ef5dd52
JB
196JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
197 in transport context, after the attempt, and per-recipient. The latter type
198 is per host attempted. The event data is the error message, and the errno
199 information encodes the lookup type (A vs. MX) used for the (first) host,
200 and the trailing two digits of the smtp 4xx reponse.
201
e161710d
GF
202GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
203 to write to mainlog (or rejectlog, paniclog) in the window between file
204 creation and permissions/ownership being changed. Particularly affects
205 installations where exicyclog is run as root, rather than exim user;
206 result is that the running daemon panics and dies.
207

208JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
209
7f06582c
JH
210JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
211 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
212 "pri" and "weight". Note that the previous implicit priority given by the
213 list order is no longer honoured.

216 for DKIM processing.

218JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
219 by defining SUPPORT_SOCKS.
74f150bf 220
cee5f132
JH
221JH/26 Move PROXY support from Experimental to mainline, enabled for a build
222 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
223 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
224 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 225

230 of the query string, and make ${quote_redis:} do that quoting.

238 cached by the daemon.

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

df3def24 280
13559da6
JH
281JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
282 either intentional arithmetic overflow during PRNG, or testing config-
283 induced overflows.
284
59eaad2b
JH
285JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
286 delivery resulted in actual delivery. Cancel cutthrough before DATA
287 stage.
288
f9334a28
JH
289JH/45 Fix cutthrough, when connection not opened by verify and target hard-
290 rejects a recipient: pass the reject to the originator.
291
dc8091e7
JH
292JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
293 Many were false-positives and ignorable, but it's worth fixing the
294 former class.
295
dfe7d917
JH
296JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
297 for the new environment-manipulation done at startup. Move the routines
298 from being local to tls.c to being global via the os.c file.

93cc2d6e
JH
300JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
301 an extract embedded as result-arg for a map, the first arg for extract
302 is unavailable so we cannot tell if this is a numbered or keyed
303 extraction. Accept either.

431TL/01 When running the test suite, the README says that variables such as
432 no_msglog_check are global and can be placed anywhere in a specific
433 test's script, however it was observed that placement needed to be near
434 the beginning for it to behave that way. Changed the runtest perl
435 script to read through the entire script once to detect and set these
436 variables, reset to the beginning of the script, and then run through
437 the script parsing/test process like normal.

794TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
795
796 When a queue runner is handling a message, Exim first routes the
797 recipient addresses, during which it prunes them based on the retry
798 hints database. After that it attempts to deliver the message to
799 any remaining recipients. It then updates the hints database using
800 the retry rules.
801
802 So if a recipient address works intermittently, it can get repeatedly
803 deferred at routing time. The retry hints record remains fresh so the
804 address never reaches the final cutoff time.
805
806 This is a fairly common occurrence when a user is bumping up against
807 their storage quota. Exim had some logic in its local delivery code
808 to deal with this. However it did not apply to per-recipient defers
809 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
810
1ddeb334
TF
811 This change adds a proper retry rule check during routing so that the
812 final cutoff time is checked against the message's age. We only do
813 this check if there is an address retry record and there is not a
814 domain retry record; this implies that previous attempts to handle
815 the address had the retry_use_local_parts option turned on. We use
816 this as an approximation for the destination being like a local
817 delivery, as in LMTP.
67bd1ab3
TF
818
819 I suspect this new check makes the old local delivery cutoff check
820 redundant, but I have not verified this so I left the code in place.

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

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

858 advertises the facility. If the client requests PRDR a new
859 acl_data_smtp_prdr ACL is called once for each recipient, after
860 the body content is received and before the acl_smtp_data ACL.
861 The client is controlled by bolth of: a hosts_try_prdr option
862 on the smtp transport, and the server advertisement.
863 Default client logging of deliveries and rejections involving
864 PRDR are flagged with the string "PRDR".

1142TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1143 lock up or crash if it happened to be inside a call to libc when it
1144 got a SIGUSR1 from exiwhat.
1145
1146 The SIGUSR1 handler appends the current process status to the process
1147 log which is later printed by exiwhat. It used to use the general
1148 purpose logging code to do this, but several functions it calls are
1149 not safe for signals.
1150
1151 The new output code in the SIGUSR1 handler is specific to the process
1152 log, and simple enough that it's easy to inspect for signal safety.
1153 Removing some special cases also simplifies the general logging code.
1154 Removing the spurious timestamps from the process log simplifies
1155 exiwhat.

TF
1157TF/04 Improved ratelimit ACL condition.
1158
1159 The /noupdate option has been deprecated in favour of /readonly which
1160 has clearer semantics. The /leaky, /strict, and /readonly update modes
1161 are mutually exclusive. The update mode is no longer included in the
1162 database key; it just determines when the database is updated. (This
1163 means that when you upgrde Exim will forget old rate measurements.)
1164
1165 Exim now checks that the per_* options are used with an update mode that
1166 makes sense for the current ACL. For example, when Exim is processing a
1167 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1168 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1169 must specify per_mail/readonly. If you omit the update mode it defaults to
1170 /leaky where that makes sense (as before) or /readonly where required.
1171
1172 The /noupdate option is now undocumented but still supported for
1173 backwards compatibility. It is equivalent to /readonly except that in
1174 ACLs where /readonly is required you may specify /leaky/noupdate or
1175 /strict/noupdate which are treated the same as /readonly.
1176
1177 A useful new feature is the /count= option. This is a generalization
1178 of the per_byte option, so that you can measure the throughput of other
1179 aggregate values. For example, the per_byte option is now equivalent
1180 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1181
1182 The per_rcpt option has been generalized using the /count= mechanism
1183 (though it's more complicated than the per_byte equivalence). When it is
1184 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1185 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1186 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1187 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1188 Note that using per_rcpt with a non-readonly update mode in more than
1189 one ACL will cause the recipients to be double-counted. (The per_mail
1190 and per_byte options don't have this problem.)
1191
1192 The handling of very low rates has changed slightly. If the computed rate
1193 is less than the event's count (usually one) then this event is the first
1194 after a long gap. In this case the rate is set to the same as this event's
1195 count, so that the first message of a spam run is counted properly.
1196
1197 The major new feature is a mechanism for counting the rate of unique
1198 events. The new per_addr option counts the number of different
1199 recipients that someone has sent messages to in the last time period. It
1200 behaves like per_rcpt if all the recipient addresses are different, but
1201 duplicate recipient addresses do not increase the measured rate. Like
1202 the /count= option this is a general mechanism, so the per_addr option
1203 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1204 example, measure the rate that a client uses different sender addresses
1205 with the options per_mail/unique=$sender_address. There are further
1206 details in the main documentation.

1752TK/01 Add preliminary DKIM support. Currently requires a forked version of
1753 ALT-N's libdkim that I have put here:
1754 http://duncanthrax.net/exim-experimental/
1755
1756 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1757 were called 'true' and it seems that C99 defines that as a reserved
1758 keyword to be used with 'bool' variable types. That means you could
1759 not include C99-style headers which use bools without triggering
1760 build errors in sieve.c.

1776-----------------
1777
1778PH/01 Another patch from the Sieve maintainer.
1779
6a3bceb1
PH
1780PH/02 When an IPv6 address is converted to a string for single-key lookup
1781 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1782 dots are used instead of colons so that keys in lsearch files need not
1783 contain colons. This was done some time before quoting was made available
1784 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1785 (notated using the quote facility) so as to distinguish them from IPv4
1786 keys. This meant that lookups for IP addresses in host lists did not work
1787 for iplsearch lookups.
1788
1789 This has been fixed by arranging for IPv6 addresses to be expressed with
1790 colons if the lookup type is iplsearch. This is not incompatible, because
1791 previously such lookups could never work.
1792
1793 The situation is now rather anomolous, since one *can* have colons in
1794 ordinary lsearch keys. However, making the change in all cases is
1795 incompatible and would probably break a number of configurations.
1796

1798 version.

MH
1800MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1801 conversion specification without a maximum field width, thereby enabling
1802 a rogue spamd server to cause a buffer overflow. While nobody in their
1803 right mind would setup Exim to query an untrusted spamd server, an
1804 attacker that gains access to a server running spamd could potentially
1805 exploit this vulnerability to run arbitrary code as the Exim user.

1807TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
1808 $primary_hostname instead of what libspf2 thinks the hosts name is.
1809
0f2cbd1b
MH
1810MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1811 a directory entry by the name of the lookup key. Previously, if a
1812 symlink pointed to a non-existing file or a file in a directory that
1813 Exim lacked permissions to read, a lookup for a key matching that
1814 symlink would fail. Now it is enough that a matching directory entry
1815 exists, symlink or not. (Bugzilla 503.)

1855PH/18 If a system quota error occurred while trying to create the file for
1856 a maildir delivery, the message "Mailbox is full" was not appended to the

1858 only to a quota excession during the actual writing of the file.

PH
1888PH/02 In an ACL statement such as
1889
1890 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1891
1892 if a client was not listed at all, or was listed with a value other than
1893 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1894 the condition was not true (as it should be), so access was not denied.
1895 The bug was that the ! inversion was incorrectly passed on to the second
1896 item. This has been fixed.
1897

1899 = and & when the dns lookup returns more than one IP address.

1904PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_

1919
f0872424
PH
1920PH/07 There was a bug in the dovecot authenticator such that the value of
1921 $auth1 could be overwritten, and so not correctly preserved, after a
1922 successful authentication. This usually meant that the value preserved by
1923 the server_setid option was incorrect.

1931 in the batch. While fixing this I discovered that the process information
1932 (output by running exiwhat) was not always getting set for -bs and -bS

1998PH/29 SMTP synchronization checks are implemented when a command is read -
1999 there is a check that no more input is waiting when there shouldn't be

2001 some time before the response is written. In this time, more input might
2002 arrive, invalidly. So now there are extra checks after an ACL has run for
2003 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2004 pipelining has not been advertised.

PH
2078 the response to the final '.' that terminates a message, but only in the
2079 case where the client has not sent further data following the '.'
2080 (unfortunately, this is allowed). However, in many cases there won't be
2081 any further data because there won't be any more messages to send. A call
2082 to select() can be used: if it shows that the input is "ready", there is
2083 either input waiting, or the socket has been closed. An attempt to read
2084 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2085 would have sent an OK response which the client would never have see.

2093Exim version 4.66
2094-----------------
2095
2096PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2097 fixed by 4.65/MH/01 (is this a record?) are fixed:
2098
2099 (i) An empty string was always treated as zero by the numeric comparison
2100 operators. This behaviour has been restored.
2101
2102 (ii) It is documented that the numeric comparison operators always treat
2103 their arguments as decimal numbers. This was broken in that numbers
2104 starting with 0 were being interpreted as octal.
2105
2106 While fixing these problems I realized that there was another issue that
2107 hadn't been noticed. Values of message_size_limit (both the global option
2108 and the transport option) were treated as octal if they started with 0.
2109 The documentation was vague. These values are now always treated as
2110 decimal, and I will make that clear in the documentation.

PH
2124PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2125 child addresses, Exim now panics and dies. Previously, because the count
2126 is held in a short int, deliveries were likely to be lost. As such a
2127 large number of recipients for a single message is ridiculous
2128 (performance will be very, very poor), I have chosen to impose a limit
2129 rather than extend the field.

2135TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2136 leftover -K file (the existence of which was triggered by #402).

2144
2145TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2146 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
2154PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2155 callout verification, Exim cached a "reject" for the entire domain. This
2156 is correct for most verifications, but it is not correct for a recipient
2157 verification with use_sender or use_postmaster set, because in that case
2158 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2159 case of MAIL FROM:<> rejection from other early rejections (e.g.
2160 rejection of HELO). When verifying a recipient using a non-null MAIL
2161 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2162 Whatever the result of the callout, the value of the domain cache is
2163 left unchanged (for any other kind of callout, getting as far as trying
2164 RCPT means that the domain itself is ok).

2198PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2200 probably the interface on which it is arriving) and not to the outgoing
2201 callout (which could be using a different interface). This has been
2202 changed to use the value of the helo_data option from the smtp transport
2203 instead - this is what is used when a message is actually being sent. If
2204 there is no remote transport (possible with a router that sets up host
2205 addresses), $smtp_active_hostname is used.

7befa435 2208 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2209 (a) The code assumed that strncpy() returns a negative number on buffer
2210 overflow, which isn't the case. Replaced with Exim's string_format()
2211 function.
2212 (b) There were several signed/unsigned issues. I just did the minimum
2213 hacking in of casts. There is scope for a larger refactoring.
2214 (c) The code used strcasecmp() which is not a standard C function.
2215 Replaced with Exim's strcmpic() function.
2216 (d) The code set only $1; it now sets $auth1 as well.
2217 (e) A simple test gave the error "authentication client didn't specify
2218 service in request". It would seem that Dovecot has changed its
2219 interface. Fortunately there's a specification; I followed it and
2220 changed what the client sends and it appears to be working now.

2225PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2226 address A is aliased to B and C, where B exists and C does not. Without
2227 -v the output is "A verified" because verification stops after a
2228 successful redirection if more than one address is generated. However,
2229 with -v the child addresses are also verified. Exim was outputting "A
2230 failed to verify" and then showing the successful verification for C,
2231 with its parentage. It now outputs "B failed to verify", showing B's
2232 parentage before showing the successful verification of C.

2235 look up a TXT record in a specific list after matching in a combined
2236 list.
2237
322050c2
PH
2238PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2239 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2240 they consult the DNS. I had assumed they would set it the way they
2241 wanted; and indeed my experiments on Linux seem to show that in some
2242 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2243 To be on the safe side, however, I have now made the interface to
2244 host_find_byname() similar to host_find_bydns(), with an argument
2245 containing the DNS resolver options. The host_find_byname() function now
2246 sets these options at its start, just as host_find_bydns() does. The smtp
2247 transport options dns_qualify_single and dns_search_parents are passed to
2248 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2249 of host_find_byname() use the default settings of RES_DEFNAMES
2250 (qualify_single) but not RES_DNSRCH (search_parents).
2251

PH
2252PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2253 spool_read_header() do less string testing, by means of a preliminary
2254 switch on the second character of optional "-foo" lines. (This is
2255 overdue, caused by the large number of possibilities that now exist.
2256 Originally there were few.) While I was there, I also converted the
2257 str(n)cmp tests so they don't re-test the leading "-" and the first
2258 character, in the hope this might squeeze out yet more improvement.

PH
2260PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2261 flag allowing group syntax was set by the header_syntax check but not
2262 turned off, possible causing trouble later; (2) The flag was not being
2263 set at all for the header_verify test, causing "group"-style headers to
2264 be rejected. I have now set it in this case, and also caused header_
2265 verify to ignore an empty address taken from a group. While doing this, I
2266 came across some other cases where the code for allowing group syntax
2267 while scanning a header line wasn't quite right (mostly, not resetting
2268 the flag correctly in the right place). These bugs could have caused
2269 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2271PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2272 with the "reply" argument non-NULL. The code, however (which originally
2273 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2274 but it didn't always do it. This confused somebody who was copying the
2275 code for some other use. I have removed all the tests.

PH
2277PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2278 feature that was used to support insecure browsers during the U.S. crypto
2279 embargo. It requires special client support, and Exim is probably the
2280 only MTA that supported it -- and would never use it because real RSA is
2281 always available. This code has been removed, because it had the bad
2282 effect of slowing Exim down by computing (never used) parameters for the
2283 RSA_EXPORT functionality.

2288 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2289 if the connection is using TLS or if the remote IP is the same as the
2290 local IP, and the "valid-client-cert option" if a client certificate has
2291 been verified.

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

2361 written to the panic log as well as the main log, but it isn't really

PH
2366PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2367 runs only) independently of the message's sender address. This meant
2368 that, if the 4xx error was in fact related to the sender, a different
2369 message to the same recipient with a different sender could confuse
2370 things. In particualar, this can happen when sending to a greylisting
2371 server, but other circumstances could also provoke similar problems.
2372 I have changed the default so that the retry time for these errors is now
2373 based a combination of the sender and recipient addresses. This change
2374 can be overridden by setting address_retry_include_sender=false in the
2375 smtp transport.

2648 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2649 554 error is used if errno is still zero or contains ENOENT (which occurs

2736 autoreply, Exim could try to deliver to a non-existent relative file

2738 it logs this as a hard delivery error, but does not attempt to create a

2770PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2771 additional section of a DNS packet that returns MX or SRV records.
2772 Instead, it always explicitly searches for A/AAAA records. This avoids
2773 major problems that occur when a DNS server includes only records of one
2774 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2775 fixed another bug: if SRV records were looked up and the corresponding
2776 address records were *not* found in the additional section, the port
2777 values from the SRV records were lost.

PH
2787PH/19 When calculating a retry time, Exim used to measure the "time since
2788 failure" by looking at the "first failed" field in the retry record. Now
2789 it does not use this if it is later than than the arrival time of the
2790 message. Instead it uses the arrival time. This makes for better
2791 behaviour in cases where some deliveries succeed, thus re-setting the
2792 "first failed" field. An example is a quota failure for a huge message
2793 when small messages continue to be delivered. Without this change, the
2794 "time since failure" will always be short, possible causing more frequent
2795 delivery attempts for the huge message than are intended.

PH
2892PH/42 The content-scanning code uses fopen() to create files in which to put
2893 message data. Previously it was not paying any attention to the mode of
2894 the files. Exim runs with umask(0) because the rest of the code creates
2895 files with open(), and sets the required mode explicitly. Thus, these
2896 files were ending up world-writeable. This was not a big issue, because,
2897 being within the spool directory, they were not world-accessible. I have
2898 created a function called modefopen, which takes an additional mode
2899 argument. It sets umask(777), creates the file, chmods it to the required
2900 mode, then resets the umask. All the relevant calls to fopen() in the

2938
2939 (i) Exim was not creating retry information for temporary errors given
2940 for individual recipients after the DATA command when the smtp transport
2941 was used in LMTP mode. This meant that they could be retried too
2942 frequently, and not timed out correctly.
2943
2944 (ii) Exim was setting the flag that allows error details to be returned
2945 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2946 recipients that were returned after the DATA command.
2947
2948PH/53 This is related to PH/52, but is more general: for any failing address,
2949 when detailed error information was permitted to be returned to the
2950 sender, but the error was temporary, then after the final timeout, only
2951 "retry timeout exceeded" was returned. Now it returns the full error as

3023 function verify_get_ident() calls ip_connect() to connect a socket, but
3024 if the "connect()" function timed out, ip_connect() used to close the
3025 socket. However, verify_get_ident() also closes the socket later, and in
3026 between Exim writes to the log, which may get opened at this point. When
3027 the socket was closed in ip_connect(), the log could get the same file
3028 descriptor number as the socket. This naturally causes chaos. The fix is
3029 not to close the socket in ip_connect(); the socket should be closed by
3030 the function that creates it. There was only one place in the code where
3031 this was missing, in the iplookup router, which I don't think anybody now
3032 uses, but I've fixed it anyway.

3094 Received: from [1.2.3.4] (helo=[1.2.3.4])

3110PH/09 Applied a patch from the Sieve maintainer which:
3111
3112 o fixes some comments
3113 o adds the (disabled) notify extension core
3114 o adds some debug output for the result of if/elsif tests
3115 o points to the current vacation draft in the documentation
3116 and documents the missing references header update
3117
3118 and most important:
3119
3120 o fixes a bug in processing the envelope test (when testing
3121 multiple envelope elements, the last element determinted the
3122 result)

3124PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3125 Electronic Mail") by including:
3126
3127 Auto-submitted: auto-generated
3128
3129 in the messages that it generates (bounce messages and others, such as
3130 warnings). In the case of bounce messages for non-SMTP mesages, there was
3131 also a typo: it was using "Auto_submitted" (underscore instead of
3132 hyphen). Since every message generated by Exim is necessarily in response
3133 to another message, thes have all been changed to:
3134
3135 Auto-Submitted: auto-replied
3136
3137 in accordance with these statements in the RFC:
3138
3139 The auto-replied keyword:
3140
3141 - SHOULD be used on messages sent in direct response to another
3142 message by an automatic process,
3143
3144 - MUST NOT be used on manually-generated messages,
3145
3146 - MAY be used on Delivery Status Notifications (DSNs) and Message
3147 Disposition Notifications (MDNs),
3148
3149 - MUST NOT be used on messages generated by automatic or periodic
3150 processes, except for messages which are automatic responses to
3151 other messages.

3162PH/14 Add check_rfc2047_length to disable enforcement of RFC 2047 length

3166PH/15 If the first argument of "${if match_address" was not empty, but did not

3172PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3173 extension "envelope-auth". The code is finished and in agreement with
3174 other implementations, but there is no documentation so far and in fact,
3175 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3176 not changing the active code.
3177
3178 Print executed "if" and "elsif" statements when debugging is used. This
3179 helps a great deal to understand what a filter does.
3180
3181 Document more things not specified clearly in RFC3028. I had all this
3182 sorted out, when out of a sudden new issues came to my mind. Oops."

3184PH/18 Exim was not recognizing the "net-" search type prefix in match_ip lists
3185 (Bugzilla #53).
3186
d27f1df3
PH
3187PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3188 canonical form (as documented). However, after a host name lookup from
3189 the IP address, check_host() was doing a simple string comparison with
3190 addresses acquired from the DNS when checking that the found name did
3191 have the original IP as one of its addresses. Since any found IPv6
3192 addresses are likely to be in abbreviated form, the comparison could
3193 fail. Luckily, there already exists a function for doing the comparison
3194 by converting both addresses to binary, so now that is used instead of
3195 the text comparison.
3196
96776534
PH
3197PH/20 There was another similar case to PH/19, when a complete host name was
3198 given in a host list; looking up its IP address could give an abbreviated
3199 form, whereas the current host's name might or might not be abbreviated.
3200 The same fix has been applied.

3215PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
3216 header line, restrict the check to what is listed in RFCs 2369 and 2929.
3217 Also, for "Auto-Submitted", treat anything other than "no" as
3218 non-personal, in accordance with RFC 3834. (Previously it treated
3219 anything starting "auto-" as non-personal.)

3221TF/01 The control=submission/name=... option had a problem with syntax
3222 errors if the name included a slash character. The /name= option
3223 now slurps the rest of the string, so it can include any characters
3224 but it must come last in the list of options (after /sender_retain
3225 or /domain=).

3242PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of

3274PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3275 run a filter in a subprocess. This could lead to confusion in subsequent

3277 the end of the subprocess.

PH
3279PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3280 only if the host matched helo_try_verify_hosts, which caused the
3281 verification to occur when the EHLO/HELO command was issued. The ACL just
3282 tested the remembered result. Now, if a previous verification attempt has
3283 not happened, "verify = helo" does it there and then.

3312PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3313 authentication with radiusclient 0.4.9:
3314
3315 - Error returned from rc_read_config was caught wrongly
3316 - Username/password not passed on to radius server due to wrong length.
3317
3318 The presumption is that some radiusclient API changes for 4.51/PH/17
3319 were not taken care of correctly. The code is still untested by me (my
3320 Linux distribution still has 0.3.2 of radiusclient), but it was
3321 contributed by a Radius user.
