JH
7JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
8 and 3.4.4 - once the server is enabled to respond to an OCSP request
9 it does even when not requested, resulting in a stapling non-aware
10 client dropping the TLS connection.

6c6d6e48
TF
12TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
13 support variable-length bit vectors. No functional change.
14
ac881e27
TF
15TF/02 Improve the consistency of logging incoming and outgoing interfaces.
16 The I= interface field on outgoing lines is now after the H= remote
17 host field, same as incoming lines. There is a separate
18 outgoing_interface log selector which allows you to disable the
19 outgoing I= field.
20
c8899c20
JH
21JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
22 If not running log_selector +smtp_connection the mainlog would be held
23 open indefinitely after a "too many connections" event, including to a
24 deleted file after a log rotate. Leave the per net connection logging
25 leaving it open for efficiency as that will be quickly detected by the
26 check on the next write.

HSHR
28HS/01 Bug 1671: Fix post transport crash.
29 Processing the wait-<transport> messages could crash the delivery
30 process if the message IDs didn't exist for some reason. When
31 using 'split_spool_directory=yes' the construction of the spool
32 file name failed already, exposing the same netto behaviour.
33

JH
34JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
35 mime_regex ACL conditions.
36
895fbaf2
JH
37JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
38 to DSN fail messages (bounces): remote IP, remote greeting, remote response
39 to HELO, local diagnostic string.
40
805bb5c3
JH
41JH/05 Downgrade message for a TLS-certificate-based authentication fail from
42 log line to debug. Even when configured with a tls authenticator many
43 client connections are expected to not authenticate in this way, so
44 an authenticate fail is not an error.
45
56c2a7be
HSHR
46HS/02 Add the Exim version string to the process info. This way exiwhat
47 gives some more detail about the running daemon.
48
14b3c5bc
JH
49JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
50 matter for fast-change records such as DNSBLs.
51
6f6dedcc
JH
52JH/07 Bug 1678: Always record an interface option value, if set, as part of a
53 retry record, even if constant. There may be multiple transports with
54 different interface settings and the retry behaviour needs to be kept
55 distinct.
56
0f557e90
JH
57JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
58
59JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.

ec0eb1a3
JH
61JH/10 Bug 840: fix log_defer_output option of pipe transport
62
41e93589
JH
63JH/11 Bug 830: use same host for all RCPTS of a message, even under
64 hosts_randomize. This matters a lot when combined with mua_wrapper.
65
98b98887 66JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
67 ${quote_pgsql:<string>} operator.
68
98b98887
JH
69JH/13 Bug 1708: avoid misaligned access in cached lookup.
70
858e91c2
JH
71JH/14 Change header file name for freeradius-client. Relevant if compiling
72 with Radius support; from the Gentoo tree and checked under Fedora.
73
74JH/15 Bug 1712: Introduce $prdr_requested flag variable
75
6ff55e50
JH
76JH/16 Bug 1714: Permit an empty string as expansion result for transport
77 option transport_filter, meaning no filtering.
78
3b957582
JB
79JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
80
23f3dc67
JH
81JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
82 defaults to "*" (all hosts). The variable is now available when not built
83 with TLS, default unset, mainly to enable keeping the testuite sane.
84 If a server certificate is not supplied (via tls_certificate) an error is
85 logged, and clients will find TLS connections fail on startup. Presumably
86 they will retry in-clear.
87 Packagers of Exim are strongly encouraged to create a server certificate
88 at installation time.
89
240c288f
JH
90HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
91 with the $config_file variable.
92
5ef5dd52
JB
93JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
94 in transport context, after the attempt, and per-recipient. The latter type
95 is per host attempted. The event data is the error message, and the errno
96 information encodes the lookup type (A vs. MX) used for the (first) host,
97 and the trailing two digits of the smtp 4xx reponse.
98

GF
99GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
100 to write to mainlog (or rejectlog, paniclog) in the window between file
101 creation and permissions/ownership being changed. Particularly affects
102 installations where exicyclog is run as root, rather than exim user;
103 result is that the running daemon panics and dies.

106Exim version 4.86
107-----------------
108JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
109 expanded.
110
506900af
JH
111JH/02 The smtp transport option "multi_domain" is now expanded.
112
ad07e9ad
JH
113JH/03 The smtp transport now requests PRDR by default, if the server offers
114 it.
115
01a4a5c5 116JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 117 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
118 can be used to disable this per-host. The build option
119 EXPERIMENTAL_CERTNAMES is withdrawn.
120
cb1d7830 121JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 122 default to the word "system" to access the system default CA bundle.
cb1d7830
JH
123 For GnuTLS, only version 3.0.20 or later.
124
610ff438 125JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
126 (but not required) by default. The verification status is now logged by
127 default, for both outbound TLS and client-certificate supplying inbound
128 TLS connections
610ff438 129
f926e272
JH
130JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
131 sites use this now.
132
50dc7409
JH
133JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
134 Status Notification (bounce) messages are now MIME format per RFC 3464.
135 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
136 under the control of the dsn_advertise_hosts option, and routers may
137 have a dsn_lasthop option.
138
0f0c8159
JH
139JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
140 default, modifiable by a malware= option. The list separator for
23763898 141 the options can now be changed in the usual way. Bug 68.
4e71661f 142
1ad6489e
JH
143JH/10 The smtp_receive_timeout main option is now expanded before use.
144
aeaf5db3

145JH/11 The incoming_interface log option now also enables logging of the
146 local interface on delivery outgoing connections.
147
5032d1cf
JH
148JH/12 The cutthrough-routing facility now supports multi-recipient mails,
149 if the interface and destination host and port all match.
150

154JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
155 Patch from Andrew Lewis.
156
fd4d8871 157JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 158 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
159 modifiers per server. Patch originally by <rommer@active.by>.
160
161JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
162 and remote servers. Remote servers can be IPv6 addresses, and
163 specify a port-range.
fd4d8871 164
23763898

JH
177JH/21 Support for the A6 type of dns record is withdrawn.
178
82c0c8ea
JH
179JH/22 Bug 608: The result of a QUIT or not-QUIT toplevel ACL now matters
180 rather than the verbs used.
181
b980ed83

HSHR
187HS/01 DNSSEC options (dnssec_require_domains, dnssec_request_domains)
188 are generic router options now. The defaults didn't change.

199
8241d8dd
JH
200JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
201 Normally benign, it bites when the pair was led to by a CNAME;
202 modern usage is to not canoicalize the domain to a CNAME target
203 (and we were inconsistent anyway for A-only vs AAAA+A).

TL
226Exim version 4.85
227-----------------
228TL/01 When running the test suite, the README says that variables such as
229 no_msglog_check are global and can be placed anywhere in a specific
230 test's script, however it was observed that placement needed to be near
231 the beginning for it to behave that way. Changed the runtest perl
232 script to read through the entire script once to detect and set these
233 variables, reset to the beginning of the script, and then run through
234 the script parsing/test process like normal.

TL
236TL/02 The BSD's have an arc4random API. One of the functions to induce
237 adding randomness was arc4random_stir(), but it has been removed in
238 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
239 function when detected.
240
a9b8ec8b
JH
241JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
242 cause callback expansion.
243
6286d7c4
TL
244TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
245 syntax errors in an expansion can be treated as a string instead of
246 logging or causing an error, due to the internal use of bool_lax
247 instead of bool when processing it.
248
0f06b4f2 249JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d

bd21a787
WB
261JH/05 Fix results-pipe from transport process. Several recipients, combined
262 with certificate use, exposed issues where response data items split
263 over buffer boundaries were not parsed properly. This eventually
264 resulted in duplicates being sent. This issue only became common enough
265 to notice due to the introduction of conection certificate information,
266 the item size being so much larger. Found and fixed by Wolfgang Breyha.
267
8bc732e8
JH
268JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
269 size buffer was used, resulting in syntax errors when an expansion
270 exceeded it.
271

272JH/07 Add support for directories of certificates when compiled with a GnuTLS
273 version 3.3.6 or later.
274
774ef2d7
JH
275JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
276 is EXPERIMENTAL_EVENT, the main-configuration and transport options
277 both become "event_action", the variables become $event_name, $event_data
aec45841 278 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
279 routers, transports and related events. The tls:cert event is now also
280 raised for inbound connections, if the main configuration event_action
281 option is defined.

286JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on

337
338TF/01 Correctly close the server side of TLS when forking for delivery.
339
340 When a message was received over SMTP with TLS, Exim failed to clear up
341 the incoming connection properly after forking off the child process to
342 deliver the message. In some situations the subsequent outgoing
343 delivery connection happened to have the same fd number as the incoming
344 connection previously had. Exim would try to use TLS and fail, logging
345 a "Bad file descriptor" error.

591TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
592
593 When a queue runner is handling a message, Exim first routes the
594 recipient addresses, during which it prunes them based on the retry
595 hints database. After that it attempts to deliver the message to
596 any remaining recipients. It then updates the hints database using
597 the retry rules.
598
599 So if a recipient address works intermittently, it can get repeatedly
600 deferred at routing time. The retry hints record remains fresh so the
601 address never reaches the final cutoff time.
602
603 This is a fairly common occurrence when a user is bumping up against
604 their storage quota. Exim had some logic in its local delivery code
605 to deal with this. However it did not apply to per-recipient defers
606 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
607
1ddeb334
TF
608 This change adds a proper retry rule check during routing so that the
609 final cutoff time is checked against the message's age. We only do
610 this check if there is an address retry record and there is not a
611 domain retry record; this implies that previous attempts to handle
612 the address had the retry_use_local_parts option turned on. We use
613 this as an approximation for the destination being like a local
614 delivery, as in LMTP.
67bd1ab3
TF
615
616 I suspect this new check makes the old local delivery cutoff check
617 redundant, but I have not verified this so I left the code in place.

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

652 Server implementation by Todd Lyons, client by JH.
653 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
654 config variable "prdr_enable" controls whether the server
655 advertises the facility. If the client requests PRDR a new
656 acl_data_smtp_prdr ACL is called once for each recipient, after
657 the body content is received and before the acl_smtp_data ACL.
658 The client is controlled by bolth of: a hosts_try_prdr option
659 on the smtp transport, and the server advertisement.
660 Default client logging of deliveries and rejections involving
661 PRDR are flagged with the string "PRDR".

TF
939TF/03 Make the exiwhat support code safe for signals. Previously Exim might
940 lock up or crash if it happened to be inside a call to libc when it
941 got a SIGUSR1 from exiwhat.
942
943 The SIGUSR1 handler appends the current process status to the process
944 log which is later printed by exiwhat. It used to use the general
945 purpose logging code to do this, but several functions it calls are
946 not safe for signals.
947
948 The new output code in the SIGUSR1 handler is specific to the process
949 log, and simple enough that it's easy to inspect for signal safety.
950 Removing some special cases also simplifies the general logging code.
951 Removing the spurious timestamps from the process log simplifies
952 exiwhat.
953
c99ce5c9
TF
954TF/04 Improved ratelimit ACL condition.
955
956 The /noupdate option has been deprecated in favour of /readonly which
957 has clearer semantics. The /leaky, /strict, and /readonly update modes
958 are mutually exclusive. The update mode is no longer included in the
959 database key; it just determines when the database is updated. (This
960 means that when you upgrde Exim will forget old rate measurements.)
961
962 Exim now checks that the per_* options are used with an update mode that
963 makes sense for the current ACL. For example, when Exim is processing a
964 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
965 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
966 must specify per_mail/readonly. If you omit the update mode it defaults to
967 /leaky where that makes sense (as before) or /readonly where required.
968
969 The /noupdate option is now undocumented but still supported for
970 backwards compatibility. It is equivalent to /readonly except that in
971 ACLs where /readonly is required you may specify /leaky/noupdate or
972 /strict/noupdate which are treated the same as /readonly.
973
974 A useful new feature is the /count= option. This is a generalization
975 of the per_byte option, so that you can measure the throughput of other
976 aggregate values. For example, the per_byte option is now equivalent
977 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
978
979 The per_rcpt option has been generalized using the /count= mechanism
980 (though it's more complicated than the per_byte equivalence). When it is
981 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
982 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
983 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
984 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
985 Note that using per_rcpt with a non-readonly update mode in more than
986 one ACL will cause the recipients to be double-counted. (The per_mail
987 and per_byte options don't have this problem.)
988
989 The handling of very low rates has changed slightly. If the computed rate
990 is less than the event's count (usually one) then this event is the first
991 after a long gap. In this case the rate is set to the same as this event's
992 count, so that the first message of a spam run is counted properly.
993
994 The major new feature is a mechanism for counting the rate of unique
995 events. The new per_addr option counts the number of different
996 recipients that someone has sent messages to in the last time period. It
997 behaves like per_rcpt if all the recipient addresses are different, but
998 duplicate recipient addresses do not increase the measured rate. Like
999 the /count= option this is a general mechanism, so the per_addr option
1000 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1001 example, measure the rate that a client uses different sender addresses
1002 with the options per_mail/unique=$sender_address. There are further
1003 details in the main documentation.

1216 the case, and it resulted in successful deliveries going unlogged.

1574
1575PH/01 Another patch from the Sieve maintainer.
1576
6a3bceb1
PH
1577PH/02 When an IPv6 address is converted to a string for single-key lookup
1578 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1579 dots are used instead of colons so that keys in lsearch files need not
1580 contain colons. This was done some time before quoting was made available
1581 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1582 (notated using the quote facility) so as to distinguish them from IPv4
1583 keys. This meant that lookups for IP addresses in host lists did not work
1584 for iplsearch lookups.
1585
1586 This has been fixed by arranging for IPv6 addresses to be expressed with
1587 colons if the lookup type is iplsearch. This is not incompatible, because
1588 previously such lookups could never work.
1589
1590 The situation is now rather anomolous, since one *can* have colons in
1591 ordinary lsearch keys. However, making the change in all cases is
1592 incompatible and would probably break a number of configurations.

MH
1597MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1598 conversion specification without a maximum field width, thereby enabling
1599 a rogue spamd server to cause a buffer overflow. While nobody in their
1600 right mind would setup Exim to query an untrusted spamd server, an
1601 attacker that gains access to a server running spamd could potentially
1602 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1607MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1608 a directory entry by the name of the lookup key. Previously, if a
1609 symlink pointed to a non-existing file or a file in a directory that
1610 Exim lacked permissions to read, a lookup for a key matching that
1611 symlink would fail. Now it is enough that a matching directory entry
1612 exists, symlink or not. (Bugzilla 503.)

1652PH/18 If a system quota error occurred while trying to create the file for
1653 a maildir delivery, the message "Mailbox is full" was not appended to the

1655 only to a quota excession during the actual writing of the file.

PH
1685PH/02 In an ACL statement such as
1686
1687 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1688
1689 if a client was not listed at all, or was listed with a value other than
1690 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1691 the condition was not true (as it should be), so access was not denied.
1692 The bug was that the ! inversion was incorrectly passed on to the second
1693 item. This has been fixed.

1696 = and & when the dns lookup returns more than one IP address.

1701PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_

1710 including adding "make clean"; (3) Added -fPIC when compiling the test
1711 dynamically loaded module, to get rid of a warning.

1713MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce

f0872424
PH
1717PH/07 There was a bug in the dovecot authenticator such that the value of

1720 the server_setid option was incorrect.

1726PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1727 run for batched SMTP input. It is now run at the start of every message
1728 in the batch. While fixing this I discovered that the process information
1729 (output by running exiwhat) was not always getting set for -bs and -bS
1730 input. This is fixed, and it now also says "batched" for BSMTP.

5a11a7b4
PH
1781PH/27 When a message times out after an over-quota error from an Exim-imposed
1782 quota, the bounce message says "mailbox is full". This message was not
1783 being given when it was a system quota that was exceeded. It now should
1784 be the same.
1785
0e20aff9
MH
1786MH/03 Made $recipients available in local_scan(). local_scan() already has
1787 better access to the recipient list through recipients_list[], but
1788 $recipients can be useful in postmaster-provided expansion strings.
1789
ca86f471
PH
1790PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1791 in the case of a MAIL command with additional options following the
1792 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1793 were accidentally chopped off.
1794
a14e5636
PH
1795PH/29 SMTP synchronization checks are implemented when a command is read -
1796 there is a check that no more input is waiting when there shouldn't be
1797 any. However, for some commands, a delay in an ACL can mean that it is
1798 some time before the response is written. In this time, more input might
1799 arrive, invalidly. So now there are extra checks after an ACL has run for
1800 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1801 pipelining has not been advertised.
1802
ec95d1a6
PH
1803PH/30 MH's patch to allow iscntrl() characters to be list separators.

PH
1809PH/32 Change the Dovecot authenticator to use read() and write() on the socket
1810 instead of the C I/O that was originally supplied, because problems were
1811 reported on Solaris.
1812
58c01c94
PH
1813PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1814 Exim which did not show up earlier: it was assuming that a call to
1815 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1816 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1817 was a macro that became an assignment, so it seemed to work. This has
1818 changed to a proper function call with a void return, hence the compile
1819 error. Exim's code has been fixed.

dee5a20a

1821PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit

79749a79
PH
1828PH/37 If a message is not accepted after it has had an id assigned (e.g.
1829 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
1830 "Completed" line in the log. When some messages of this type were
1831 selected by exigrep, they were listed as "not completed". Others were

1833 criteria to be more general.
79749a79 1834
c456d9bb
PH
1835PH/38 The host_find_failed option in the manualroute router can now be set
1836 to "ignore", to completely ignore a host whose IP address cannot be

1838 host_all_ignored option.
1839
cd9868ec
PH
1840PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1841 homing or because of multiple MX records with /mx) generated more than
1842 one IP address, and the following item turned out to be the local host,
1843 all the secondary addresses of the first item were incorrectly removed
1844 from the list, along with the local host and any following hosts (which
1845 is what is supposed to happen).
1846
ebeaf996
PH
1847PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1848 whoever called Exim into the -H file. In the case of the daemon it was
1849 behaving confusingly. When first started, it used values for whoever
1850 started the daemon, but after a SIGHUP it used the Exim user (because it
1851 calls itself on a restart). I have changed the code so that it now always
1852 uses the Exim user.
1853
2679d413
PH
1854PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1855 message are rejected with the same error (e.g. no authentication or bad
1856 sender address), and a DATA command is nevertheless sent (as can happen
1857 with PIPELINING or a stupid MUA), the error message that was given to the
1858 RCPT commands is included in the rejection of the DATA command. This is
1859 intended to be helpful for MUAs that show only the final error to their
1860 users.

1873
58eb016e 1874PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1875 the response to the final '.' that terminates a message, but only in the
1876 case where the client has not sent further data following the '.'
1877 (unfortunately, this is allowed). However, in many cases there won't be
1878 any further data because there won't be any more messages to send. A call
1879 to select() can be used: if it shows that the input is "ready", there is
1880 either input waiting, or the socket has been closed. An attempt to read
1881 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1882 would have sent an OK response which the client would never have see.
563b63fa
PH
1883 This could lead to message repetition. This fix should cure that, at
1884 least in a lot of common cases.

1891-----------------
1892
1893PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1894 fixed by 4.65/MH/01 (is this a record?) are fixed:
1895
1896 (i) An empty string was always treated as zero by the numeric comparison
1897 operators. This behaviour has been restored.
1898
1899 (ii) It is documented that the numeric comparison operators always treat
1900 their arguments as decimal numbers. This was broken in that numbers
1901 starting with 0 were being interpreted as octal.
1902
1903 While fixing these problems I realized that there was another issue that
1904 hadn't been noticed. Values of message_size_limit (both the global option
1905 and the transport option) were treated as octal if they started with 0.
1906 The documentation was vague. These values are now always treated as
1907 decimal, and I will make that clear in the documentation.

PH
1921PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1922 child addresses, Exim now panics and dies. Previously, because the count
1923 is held in a short int, deliveries were likely to be lost. As such a
1924 large number of recipients for a single message is ridiculous
1925 (performance will be very, very poor), I have chosen to impose a limit
1926 rather than extend the field.

TK
1932TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1933 leftover -K file (the existence of which was triggered by #402).
1934 While we were at it, introduced process PID as part of the -K
1935 filename. This should rule out race conditions when creating
1936 these files.
1937
1938TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1939 processing considerably. Previous code took too long for large mails,
1940 triggering a timeout which in turn triggers #401.
1941
1942TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1943 in the DK code in transports.c. sendfile() is not really portable,
1944 hence the _LINUX specificness.

1946TF/01 In the add_headers option to the mail command in an Exim filter,

2b1c6e3a
PH
1951PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1952 callout verification, Exim cached a "reject" for the entire domain. This
1953 is correct for most verifications, but it is not correct for a recipient
1954 verification with use_sender or use_postmaster set, because in that case
1955 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1956 case of MAIL FROM:<> rejection from other early rejections (e.g.
1957 rejection of HELO). When verifying a recipient using a non-null MAIL
1958 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1959 Whatever the result of the callout, the value of the domain cache is
1960 left unchanged (for any other kind of callout, getting as far as trying
1961 RCPT means that the domain itself is ok).

1995PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1996 hostname. This is wrong, because it relates to the incoming message (and
1997 probably the interface on which it is arriving) and not to the outgoing
1998 callout (which could be using a different interface). This has been
1999 changed to use the value of the helo_data option from the smtp transport
2000 instead - this is what is used when a message is actually being sent. If
2001 there is no remote transport (possible with a router that sets up host
2002 addresses), $smtp_active_hostname is used.

7befa435 2005 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2006 (a) The code assumed that strncpy() returns a negative number on buffer
2007 overflow, which isn't the case. Replaced with Exim's string_format()
2008 function.
2009 (b) There were several signed/unsigned issues. I just did the minimum
2010 hacking in of casts. There is scope for a larger refactoring.
2011 (c) The code used strcasecmp() which is not a standard C function.
2012 Replaced with Exim's strcmpic() function.
2013 (d) The code set only $1; it now sets $auth1 as well.
2014 (e) A simple test gave the error "authentication client didn't specify
2015 service in request". It would seem that Dovecot has changed its
2016 interface. Fortunately there's a specification; I followed it and
2017 changed what the client sends and it appears to be working now.

2023 address A is aliased to B and C, where B exists and C does not. Without
2024 -v the output is "A verified" because verification stops after a
2025 successful redirection if more than one address is generated. However,
2026 with -v the child addresses are also verified. Exim was outputting "A
2027 failed to verify" and then showing the successful verification for C,
2028 with its parentage. It now outputs "B failed to verify", showing B's
2029 parentage before showing the successful verification of C.

PH
2035PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2036 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2037 they consult the DNS. I had assumed they would set it the way they
2038 wanted; and indeed my experiments on Linux seem to show that in some
2039 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2040 To be on the safe side, however, I have now made the interface to
2041 host_find_byname() similar to host_find_bydns(), with an argument
2042 containing the DNS resolver options. The host_find_byname() function now
2043 sets these options at its start, just as host_find_bydns() does. The smtp
2044 transport options dns_qualify_single and dns_search_parents are passed to
2045 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2046 of host_find_byname() use the default settings of RES_DEFNAMES
2047 (qualify_single) but not RES_DNSRCH (search_parents).

2049PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2050 spool_read_header() do less string testing, by means of a preliminary
2051 switch on the second character of optional "-foo" lines. (This is
2052 overdue, caused by the large number of possibilities that now exist.
2053 Originally there were few.) While I was there, I also converted the
2054 str(n)cmp tests so they don't re-test the leading "-" and the first
2055 character, in the hope this might squeeze out yet more improvement.

PH
2057PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2058 flag allowing group syntax was set by the header_syntax check but not
2059 turned off, possible causing trouble later; (2) The flag was not being
2060 set at all for the header_verify test, causing "group"-style headers to
2061 be rejected. I have now set it in this case, and also caused header_
2062 verify to ignore an empty address taken from a group. While doing this, I
2063 came across some other cases where the code for allowing group syntax
2064 while scanning a header line wasn't quite right (mostly, not resetting
2065 the flag correctly in the right place). These bugs could have caused
2066 trouble for malformed header lines. I hope it is now all correct.

PH
2068PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2069 with the "reply" argument non-NULL. The code, however (which originally
2070 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2071 but it didn't always do it. This confused somebody who was copying the
2072 code for some other use. I have removed all the tests.

PH
2074PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2075 feature that was used to support insecure browsers during the U.S. crypto
2076 embargo. It requires special client support, and Exim is probably the
2077 only MTA that supported it -- and would never use it because real RSA is
2078 always available. This code has been removed, because it had the bad
2079 effect of slowing Exim down by computing (never used) parameters for the
2080 RSA_EXPORT functionality.

PH
2082PH/21 On the advice of Timo Sirainen, added a check to the dovecot

2085 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2086 if the connection is using TLS or if the remote IP is the same as the
2087 local IP, and the "valid-client-cert option" if a client certificate has
2088 been verified.

2119
2120PH/30 Exim was sometimes attempting to deliver messages that had suffered
2121 address errors (4xx response to RCPT) over the same connection as other
2122 messages routed to the same hosts. Such deliveries are always "forced",
2123 so retry times are not inspected. This resulted in far too many retries
2124 for the affected addresses. The effect occurred only when there were more
2125 hosts than the hosts_max_try setting in the smtp transport when it had
2126 the 4xx errors. Those hosts that it had tried were not added to the list
2127 of hosts for which the message was waiting, so if all were tried, there
2128 was no problem. Two fixes have been applied:
2129
2130 (i) If there are any address or message errors in an SMTP delivery, none
2131 of the hosts (tried or untried) are now added to the list of hosts
2132 for which the message is waiting, so the message should not be a
2133 candidate for sending over the same connection that was used for a
2134 successful delivery of some other message. This seems entirely
2135 reasonable: after all the message is NOT "waiting for some host".
2136 This is so "obvious" that I'm not sure why it wasn't done
2137 previously. Hope I haven't missed anything, but it can't do any
2138 harm, as the worst effect is to miss an optimization.
2139
2140 (ii) If, despite (i), such a delivery is accidentally attempted, the
2141 routing retry time is respected, so at least it doesn't keep
2142 hammering the server.

2157PH/35 The error "getsockname() failed: connection reset by peer" was being
2158 written to the panic log as well as the main log, but it isn't really
2159 panic-worthy as it just means the connection died rather early on. I have
2160 removed the panic log writing for the ECONNRESET error when getsockname()
2161 fails.
2162
48c7f9e2
PH
2163PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2164 runs only) independently of the message's sender address. This meant
2165 that, if the 4xx error was in fact related to the sender, a different
2166 message to the same recipient with a different sender could confuse
2167 things. In particualar, this can happen when sending to a greylisting
2168 server, but other circumstances could also provoke similar problems.
2169 I have changed the default so that the retry time for these errors is now
2170 based a combination of the sender and recipient addresses. This change
2171 can be overridden by setting address_retry_include_sender=false in the
2172 smtp transport.

2440PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2442 Unfortunately, if there is a major crisis, such as a disk failure,
2443 tcp-wrappers gives "deny", whereas what one would like would be some
2444 kind of temporary error. A kludge has been added to help with this.
2445 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2446 554 error is used if errno is still zero or contains ENOENT (which occurs
2447 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2448 451 error is used.

2484PH/01 The code for finding all the local interface addresses on a FreeBSD
2485 system running IPv6 was broken. This may well have applied to all BSD
2486 systems, as well as to others that have similar system calls. The broken
2487 code found IPv4 interfaces correctly, but gave incorrect values for the
2488 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2489 that it would not match correctly against @[] and not recognize the IPv6
2490 addresses as local.

2533 autoreply, Exim could try to deliver to a non-existent relative file

2556 (a) Failures to set uid/gid, the current directory, or a process leader
2557 in a subprocess such as that created by queryprogram now generate
2558 suitable debugging ouput when -d is set.
2559

2568 additional section of a DNS packet that returns MX or SRV records.
2569 Instead, it always explicitly searches for A/AAAA records. This avoids
2570 major problems that occur when a DNS server includes only records of one
2571 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2572 fixed another bug: if SRV records were looked up and the corresponding
2573 address records were *not* found in the additional section, the port
2574 values from the SRV records were lost.

2576PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2584PH/19 When calculating a retry time, Exim used to measure the "time since
2585 failure" by looking at the "first failed" field in the retry record. Now
2586 it does not use this if it is later than than the arrival time of the
2587 message. Instead it uses the arrival time. This makes for better
2588 behaviour in cases where some deliveries succeed, thus re-setting the
2589 "first failed" field. An example is a quota failure for a huge message
2590 when small messages continue to be delivered. Without this change, the
2591 "time since failure" will always be short, possible causing more frequent
2592 delivery attempts for the huge message than are intended.

2689PH/42 The content-scanning code uses fopen() to create files in which to put

2692 files with open(), and sets the required mode explicitly. Thus, these
2693 files were ending up world-writeable. This was not a big issue, because,
2694 being within the spool directory, they were not world-accessible. I have
2695 created a function called modefopen, which takes an additional mode
2696 argument. It sets umask(777), creates the file, chmods it to the required
2697 mode, then resets the umask. All the relevant calls to fopen() in the

2724PH/50 When an Exim quota was set without a file count quota, and mailbox_size
2725 was also set, the appendfile transport was unnecessarily scanning a
2726 directory of message files (e.g. for maildir delivery) to find the count
2727 of files (along with the size), even though it did not need this
2728 information. It now does the scan only if it needs to find either the
2729 size of the count of files.

2733PH/52 Two bugs concerned with error handling when the smtp transport is
2734 used in LMTP mode:
2735
2736 (i) Exim was not creating retry information for temporary errors given
2737 for individual recipients after the DATA command when the smtp transport
2738 was used in LMTP mode. This meant that they could be retried too
2739 frequently, and not timed out correctly.
2740
2741 (ii) Exim was setting the flag that allows error details to be returned
2742 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2743 recipients that were returned after the DATA command.
2744
2745PH/53 This is related to PH/52, but is more general: for any failing address,
2746 when detailed error information was permitted to be returned to the
2747 sender, but the error was temporary, then after the final timeout, only
2748 "retry timeout exceeded" was returned. Now it returns the full error as
2749 well as "retry timeout exceeded".

2805PH/68 The bounce_return_message and bounce_return_body options were not being
2806 honoured for bounces generated during the reception of non-SMTP messages.
2807 In particular, this applied to messages rejected by the ACL. This bug has
2808 been fixed. However, if bounce_return_message is true and bounce_return_
2809 body is false, the headers that are returned for a non-SMTP message
2810 include only those that have been read before the error was detected.

PH
2819PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2820 function verify_get_ident() calls ip_connect() to connect a socket, but
2821 if the "connect()" function timed out, ip_connect() used to close the
2822 socket. However, verify_get_ident() also closes the socket later, and in
2823 between Exim writes to the log, which may get opened at this point. When
2824 the socket was closed in ip_connect(), the log could get the same file
2825 descriptor number as the socket. This naturally causes chaos. The fix is
2826 not to close the socket in ip_connect(); the socket should be closed by
2827 the function that creates it. There was only one place in the code where
2828 this was missing, in the iplookup router, which I don't think anybody now
2829 uses, but I've fixed it anyway.

2848PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2849
2850 (1) Generate an error if the third argument for the ${prvs expansion is
2851 not a single digit.
2852
2853 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2854 string.
2855
2856 (3) Reset the variables that are obtained from the first argument of
2857 ${prvscheck and used in the second argument before leaving the code,
2858 because their memory is reclaimed, so using them afterwards may do
2859 silly things.
2860
2861 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2862 one (it's much easier than Tom thought :-).
2863
2864 (5) Because of (4), we can now allow for the use of $prvscheck_result
2865 inside the third argument.

2876
2877 => >A.N.Other <ano@some.domain> <original@ddress> ...
2878
2879 This has been changed so that it extracts the operative address. There
2880 may be more than one such address. If so, they are comma-separated, like
2881 this:
2882
2883 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2885PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2886 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2887 not being looked up in the rDNS to get a host name, Exim was showing the
2888 IP address twice in Received: lines, even though the IP addresses were
2889 identical. For example:
2890
2891 Received: from [1.2.3.4] (helo=[1.2.3.4])
2892
2893 However, if the real host name was known, it was omitting the HELO data
2894 if it matched the actual IP address. This has been tidied up so that it
2895 doesn't show the same IP address twice.

2897PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2921PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2922 Electronic Mail") by including:
2923
2924 Auto-submitted: auto-generated
2925
2926 in the messages that it generates (bounce messages and others, such as
2927 warnings). In the case of bounce messages for non-SMTP mesages, there was
2928 also a typo: it was using "Auto_submitted" (underscore instead of
2929 hyphen). Since every message generated by Exim is necessarily in response
2930 to another message, thes have all been changed to:
2931
2932 Auto-Submitted: auto-replied
2933
2934 in accordance with these statements in the RFC:
2935
2936 The auto-replied keyword:
2937
2938 - SHOULD be used on messages sent in direct response to another
2939 message by an automatic process,
2940
2941 - MUST NOT be used on manually-generated messages,
2942
2943 - MAY be used on Delivery Status Notifications (DSNs) and Message
2944 Disposition Notifications (MDNs),
2945
2946 - MUST NOT be used on messages generated by automatic or periodic
2947 processes, except for messages which are automatic responses to
2948 other messages.

2972 nobody wrote the draft yet. This extension is currently #undef'ed, thus
2973 not changing the active code.

PH
2984PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2985 canonical form (as documented). However, after a host name lookup from
2986 the IP address, check_host() was doing a simple string comparison with
2987 addresses acquired from the DNS when checking that the found name did
2988 have the original IP as one of its addresses. Since any found IPv6
2989 addresses are likely to be in abbreviated form, the comparison could
2990 fail. Luckily, there already exists a function for doing the comparison
2991 by converting both addresses to binary, so now that is used instead of
2992 the text comparison.
2993
96776534
PH
2994PH/20 There was another similar case to PH/19, when a complete host name was

2997 The same fix has been applied.

3170PH/36 When a locally submitted message by a trusted user did not contain a
3171 From: header, and the sender address was obtained from -f or from an SMTP
3172 MAIL command, and the trusted user did not use -F to supply a sender
3173 name, $originator_name was incorrectly used when constructing a From:
3174 header. Furthermore, $originator_name was used for submission mode
3175 messages from external hosts without From: headers in a similar way,
3176 which is clearly wrong.

3289PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3290 with the definition in sysexits.h (which is #included earlier).
3291 Fortunately, Exim does not actually use EX_OK. The code used to try to
3292 preserve the sysexits.h value, by assumimg that macro definitions were
3293 scanned for macro replacements. I have been disabused of this notion,
3294 so now the code just undefines EX_OK before #including unistd.h.

3296PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3297 in the smtp transport. When a block could not be written in a single
3298 write() function, the timeout was being re-applied to each part-write.
3299 This seems wrong - if the receiver was accepting one byte at a time it
3300 would take for ever. The timeout is now adjusted when this happens. It
3301 doesn't have to be particularly precise.
