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.

TF
12TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
13 support variable-length bit vectors. No functional change.
14

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.

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.

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.

JH
34JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
35 mime_regex ACL conditions.

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.

46HS/02 Add the Exim version string to the process info. This way exiwhat
47 gives some more detail about the running daemon.

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.

57JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.

62

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

JH
69JH/13 Bug 1708: avoid misaligned access in cached lookup.

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.

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.
104

JH
105JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
106
7f06582c
JH
107JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
108 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
109 "pri" and "weight". Note that the previous implicit priority given by the
110 list order is no longer honoured.

113 for DKIM processing.

115JH/23 Move SOCKS5 support from Experimental to mainline, enabled for a build
116 by defining SUPPORT_SOCKS.
74f150bf 117
cee5f132
JH
118JH/26 Move PROXY support from Experimental to mainline, enabled for a build
119 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
120 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
121 variables are renamed to proxy_{local,external}_{address,port}.

JH
140JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
141 keys are given for lookup.
142
f444c2c7
JH
143JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
144 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
145 only supported when built with TLS support. The PolarSSL SHA routines
146 are still used when the TLS library is too old for convenient support.
f444c2c7 147
a57b6200
JH
148JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
149 openssl_options), for security. OpenSSL forces this from version 1.1.0
150 server-side so match that on older versions.
151
07c73177 152JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 153 allocation for $value could be released as the expansion processing
07c73177 154 concluded, but leaving the global pointer active for it.
fa01e4f8 155
4f6ae5c3
JH
156JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
157 and to use the domains and local_parts ACL conditions.
158
1bc460a6
JH
159JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
160 incorrectly not doubled on cutthrough transmission, hence seen as a
161 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 162 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
163 via the normal store-and-forward channel. This could result in duplicates
164 received - but deduplicating mailstores were liable to retain only the
165 initial truncated version.
166
ab9152ff 167JH/39 Bug 1781: Fix use of DKIM private-keys having trailing '=' in the base-64.

13559da6
JH
178JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
179 either intentional arithmetic overflow during PRNG, or testing config-
180 induced overflows.

182JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
183 delivery resulted in actual delivery. Cancel cutthrough before DATA
184 stage.

196JH/02 The smtp transport option "multi_domain" is now expanded.
197
ad07e9ad

199 it.
200
01a4a5c5 201JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 202 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
203 can be used to disable this per-host. The build option
204 EXPERIMENTAL_CERTNAMES is withdrawn.
205

JH
208 For GnuTLS, only version 3.0.20 or later.
209
610ff438 210JH/06 Verification of the server certificate for a TLS connection is now tried

211 (but not required) by default. The verification status is now logged by
212 default, for both outbound TLS and client-certificate supplying inbound
213 TLS connections
610ff438 214

JH
218JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
219 Status Notification (bounce) messages are now MIME format per RFC 3464.
220 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
221 under the control of the dsn_advertise_hosts option, and routers may
222 have a dsn_lasthop option.
223
0f0c8159

224JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
225 default, modifiable by a malware= option. The list separator for
23763898 226 the options can now be changed in the usual way. Bug 68.
4e71661f 227

230JH/11 The incoming_interface log option now also enables logging of the
231 local interface on delivery outgoing connections.
232
5032d1cf

240 Patch from Andrew Lewis.
241
fd4d8871 242JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 243 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
244 modifiers per server. Patch originally by <rommer@active.by>.
245
246JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
247 and remote servers. Remote servers can be IPv6 addresses, and
248 specify a port-range.
fd4d8871 249

JH
262JH/21 Support for the A6 type of dns record is withdrawn.
263
82c0c8ea
JH
264JH/22 Bug 608: The result of a QUIT or not-QUIT toplevel ACL now matters
265 rather than the verbs used.
266
b980ed83

284
8241d8dd
JH
285JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
286 Normally benign, it bites when the pair was led to by a CNAME;
287 modern usage is to not canoicalize the domain to a CNAME target
288 (and we were inconsistent anyway for A-only vs AAAA+A).

311Exim version 4.85
312-----------------
313TL/01 When running the test suite, the README says that variables such as
314 no_msglog_check are global and can be placed anywhere in a specific
315 test's script, however it was observed that placement needed to be near
316 the beginning for it to behave that way. Changed the runtest perl
317 script to read through the entire script once to detect and set these
318 variables, reset to the beginning of the script, and then run through
319 the script parsing/test process like normal.

329TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
330 syntax errors in an expansion can be treated as a string instead of

WB
346JH/05 Fix results-pipe from transport process. Several recipients, combined
347 with certificate use, exposed issues where response data items split
348 over buffer boundaries were not parsed properly. This eventually
349 resulted in duplicates being sent. This issue only became common enough
350 to notice due to the introduction of conection certificate information,
351 the item size being so much larger. Found and fixed by Wolfgang Breyha.

360JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
361 is EXPERIMENTAL_EVENT, the main-configuration and transport options
362 both become "event_action", the variables become $event_name, $event_data
aec45841 363 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
364 routers, transports and related events. The tls:cert event is now also
365 raised for inbound connections, if the main configuration event_action
366 option is defined.

424
425 When a message was received over SMTP with TLS, Exim failed to clear up
426 the incoming connection properly after forking off the child process to
427 deliver the message. In some situations the subsequent outgoing
428 delivery connection happened to have the same fd number as the incoming
429 connection previously had. Exim would try to use TLS and fail, logging

676TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
677
678 When a queue runner is handling a message, Exim first routes the
679 recipient addresses, during which it prunes them based on the retry
680 hints database. After that it attempts to deliver the message to
681 any remaining recipients. It then updates the hints database using
682 the retry rules.
683
684 So if a recipient address works intermittently, it can get repeatedly
685 deferred at routing time. The retry hints record remains fresh so the
686 address never reaches the final cutoff time.
687
688 This is a fairly common occurrence when a user is bumping up against
689 their storage quota. Exim had some logic in its local delivery code
690 to deal with this. However it did not apply to per-recipient defers
691 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
692
1ddeb334
TF
693 This change adds a proper retry rule check during routing so that the
694 final cutoff time is checked against the message's age. We only do
695 this check if there is an address retry record and there is not a
696 domain retry record; this implies that previous attempts to handle
697 the address had the retry_use_local_parts option turned on. We use
698 this as an approximation for the destination being like a local
699 delivery, as in LMTP.
67bd1ab3
TF
700
701 I suspect this new check makes the old local delivery cutoff check
702 redundant, but I have not verified this so I left the code in place.

742 the body content is received and before the acl_smtp_data ACL.
743 The client is controlled by bolth of: a hosts_try_prdr option
744 on the smtp transport, and the server advertisement.

1024TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1025 lock up or crash if it happened to be inside a call to libc when it
1026 got a SIGUSR1 from exiwhat.
1027
1028 The SIGUSR1 handler appends the current process status to the process
1029 log which is later printed by exiwhat. It used to use the general
1030 purpose logging code to do this, but several functions it calls are
1031 not safe for signals.
1032
1033 The new output code in the SIGUSR1 handler is specific to the process
1034 log, and simple enough that it's easy to inspect for signal safety.
1035 Removing some special cases also simplifies the general logging code.
1036 Removing the spurious timestamps from the process log simplifies
1037 exiwhat.
1038

TF
1039TF/04 Improved ratelimit ACL condition.
1040
1041 The /noupdate option has been deprecated in favour of /readonly which
1042 has clearer semantics. The /leaky, /strict, and /readonly update modes
1043 are mutually exclusive. The update mode is no longer included in the
1044 database key; it just determines when the database is updated. (This
1045 means that when you upgrde Exim will forget old rate measurements.)
1046
1047 Exim now checks that the per_* options are used with an update mode that
1048 makes sense for the current ACL. For example, when Exim is processing a
1049 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1050 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1051 must specify per_mail/readonly. If you omit the update mode it defaults to
1052 /leaky where that makes sense (as before) or /readonly where required.
1053
1054 The /noupdate option is now undocumented but still supported for
1055 backwards compatibility. It is equivalent to /readonly except that in
1056 ACLs where /readonly is required you may specify /leaky/noupdate or
1057 /strict/noupdate which are treated the same as /readonly.
1058
1059 A useful new feature is the /count= option. This is a generalization
1060 of the per_byte option, so that you can measure the throughput of other
1061 aggregate values. For example, the per_byte option is now equivalent
1062 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1063
1064 The per_rcpt option has been generalized using the /count= mechanism
1065 (though it's more complicated than the per_byte equivalence). When it is
1066 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1067 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1068 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1069 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1070 Note that using per_rcpt with a non-readonly update mode in more than
1071 one ACL will cause the recipients to be double-counted. (The per_mail
1072 and per_byte options don't have this problem.)
1073
1074 The handling of very low rates has changed slightly. If the computed rate
1075 is less than the event's count (usually one) then this event is the first
1076 after a long gap. In this case the rate is set to the same as this event's
1077 count, so that the first message of a spam run is counted properly.
1078
1079 The major new feature is a mechanism for counting the rate of unique
1080 events. The new per_addr option counts the number of different
1081 recipients that someone has sent messages to in the last time period. It
1082 behaves like per_rcpt if all the recipient addresses are different, but
1083 duplicate recipient addresses do not increase the measured rate. Like
1084 the /count= option this is a general mechanism, so the per_addr option
1085 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1086 example, measure the rate that a client uses different sender addresses
1087 with the options per_mail/unique=$sender_address. There are further
1088 details in the main documentation.

1638 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1639 were called 'true' and it seems that C99 defines that as a reserved
1640 keyword to be used with 'bool' variable types. That means you could
1641 not include C99-style headers which use bools without triggering
1642 build errors in sieve.c.

1657Exim version 4.68
1658-----------------
1659
1660PH/01 Another patch from the Sieve maintainer.
1661
6a3bceb1
PH
1662PH/02 When an IPv6 address is converted to a string for single-key lookup
1663 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1664 dots are used instead of colons so that keys in lsearch files need not
1665 contain colons. This was done some time before quoting was made available
1666 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1667 (notated using the quote facility) so as to distinguish them from IPv4
1668 keys. This meant that lookups for IP addresses in host lists did not work
1669 for iplsearch lookups.
1670
1671 This has been fixed by arranging for IPv6 addresses to be expressed with
1672 colons if the lookup type is iplsearch. This is not incompatible, because
1673 previously such lookups could never work.
1674
1675 The situation is now rather anomolous, since one *can* have colons in
1676 ordinary lsearch keys. However, making the change in all cases is
1677 incompatible and would probably break a number of configurations.

MH
1682MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1683 conversion specification without a maximum field width, thereby enabling
1684 a rogue spamd server to cause a buffer overflow. While nobody in their
1685 right mind would setup Exim to query an untrusted spamd server, an
1686 attacker that gains access to a server running spamd could potentially
1687 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1692MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1693 a directory entry by the name of the lookup key. Previously, if a
1694 symlink pointed to a non-existing file or a file in a directory that
1695 Exim lacked permissions to read, a lookup for a key matching that
1696 symlink would fail. Now it is enough that a matching directory entry
1697 exists, symlink or not. (Bugzilla 503.)

1770PH/02 In an ACL statement such as

1774 if a client was not listed at all, or was listed with a value other than
1775 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1776 the condition was not true (as it should be), so access was not denied.

PH
1880PH/29 SMTP synchronization checks are implemented when a command is read -
1881 there is a check that no more input is waiting when there shouldn't be
1882 any. However, for some commands, a delay in an ACL can mean that it is
1883 some time before the response is written. In this time, more input might
1884 arrive, invalidly. So now there are extra checks after an ACL has run for
1885 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1886 pipelining has not been advertised.

PH
1898PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1900 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1901 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1902 was a macro that became an assignment, so it seemed to work. This has
1903 changed to a proper function call with a void return, hence the compile
1904 error. Exim's code has been fixed.

1935 started the daemon, but after a SIGHUP it used the Exim user (because it

1942 with PIPELINING or a stupid MUA), the error message that was given to the
1943 RCPT commands is included in the rejection of the DATA command. This is
1944 intended to be helpful for MUAs that show only the final error to their

58eb016e 1959PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1960 the response to the final '.' that terminates a message, but only in the
1961 case where the client has not sent further data following the '.'
1962 (unfortunately, this is allowed). However, in many cases there won't be
1963 any further data because there won't be any more messages to send. A call
1964 to select() can be used: if it shows that the input is "ready", there is
1965 either input waiting, or the socket has been closed. An attempt to read
1966 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1967 would have sent an OK response which the client would never have see.

1976-----------------
1977
1978PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1979 fixed by 4.65/MH/01 (is this a record?) are fixed:
1980
1981 (i) An empty string was always treated as zero by the numeric comparison
1982 operators. This behaviour has been restored.
1983
1984 (ii) It is documented that the numeric comparison operators always treat
1985 their arguments as decimal numbers. This was broken in that numbers
1986 starting with 0 were being interpreted as octal.
1987
1988 While fixing these problems I realized that there was another issue that
1989 hadn't been noticed. Values of message_size_limit (both the global option
1990 and the transport option) were treated as octal if they started with 0.
1991 The documentation was vague. These values are now always treated as
1992 decimal, and I will make that clear in the documentation.

2006PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2007 child addresses, Exim now panics and dies. Previously, because the count
2008 is held in a short int, deliveries were likely to be lost. As such a
2009 large number of recipients for a single message is ridiculous
2010 (performance will be very, very poor), I have chosen to impose a limit
2011 rather than extend the field.

2017TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2018 leftover -K file (the existence of which was triggered by #402).
2019 While we were at it, introduced process PID as part of the -K
2020 filename. This should rule out race conditions when creating
2021 these files.
2022
2023TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2024 processing considerably. Previous code took too long for large mails,
2025 triggering a timeout which in turn triggers #401.
2026
2027TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2028 in the DK code in transports.c. sendfile() is not really portable,
2029 hence the _LINUX specificness.

2031TF/01 In the add_headers option to the mail command in an Exim filter,

2033 header after the first one which had an odd number of characters
2034 in the field name.

PH
2036PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2037 callout verification, Exim cached a "reject" for the entire domain. This
2038 is correct for most verifications, but it is not correct for a recipient
2039 verification with use_sender or use_postmaster set, because in that case
2040 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2041 case of MAIL FROM:<> rejection from other early rejections (e.g.
2042 rejection of HELO). When verifying a recipient using a non-null MAIL
2043 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2044 Whatever the result of the callout, the value of the domain cache is
2045 left unchanged (for any other kind of callout, getting as far as trying
2046 RCPT means that the domain itself is ok).

2080PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2081 hostname. This is wrong, because it relates to the incoming message (and
2082 probably the interface on which it is arriving) and not to the outgoing
2083 callout (which could be using a different interface). This has been
2084 changed to use the value of the helo_data option from the smtp transport
2085 instead - this is what is used when a message is actually being sent. If
2086 there is no remote transport (possible with a router that sets up host
2087 addresses), $smtp_active_hostname is used.

14aa5a05 2089PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2090 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2091 (a) The code assumed that strncpy() returns a negative number on buffer
2092 overflow, which isn't the case. Replaced with Exim's string_format()
2093 function.
2094 (b) There were several signed/unsigned issues. I just did the minimum
2095 hacking in of casts. There is scope for a larger refactoring.
2096 (c) The code used strcasecmp() which is not a standard C function.
2097 Replaced with Exim's strcmpic() function.
2098 (d) The code set only $1; it now sets $auth1 as well.
2099 (e) A simple test gave the error "authentication client didn't specify
2100 service in request". It would seem that Dovecot has changed its
2101 interface. Fortunately there's a specification; I followed it and
2102 changed what the client sends and it appears to be working now.

2107PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2108 address A is aliased to B and C, where B exists and C does not. Without
2109 -v the output is "A verified" because verification stops after a
2110 successful redirection if more than one address is generated. However,
2111 with -v the child addresses are also verified. Exim was outputting "A
2112 failed to verify" and then showing the successful verification for C,
2113 with its parentage. It now outputs "B failed to verify", showing B's
2114 parentage before showing the successful verification of C.

2117 look up a TXT record in a specific list after matching in a combined
2118 list.
2119
322050c2
PH
2120PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2121 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2122 they consult the DNS. I had assumed they would set it the way they
2123 wanted; and indeed my experiments on Linux seem to show that in some
2124 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2125 To be on the safe side, however, I have now made the interface to
2126 host_find_byname() similar to host_find_bydns(), with an argument
2127 containing the DNS resolver options. The host_find_byname() function now
2128 sets these options at its start, just as host_find_bydns() does. The smtp
2129 transport options dns_qualify_single and dns_search_parents are passed to
2130 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2131 of host_find_byname() use the default settings of RES_DEFNAMES
2132 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2134PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2135 spool_read_header() do less string testing, by means of a preliminary
2136 switch on the second character of optional "-foo" lines. (This is
2137 overdue, caused by the large number of possibilities that now exist.
2138 Originally there were few.) While I was there, I also converted the
2139 str(n)cmp tests so they don't re-test the leading "-" and the first
2140 character, in the hope this might squeeze out yet more improvement.

PH
2142PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2143 flag allowing group syntax was set by the header_syntax check but not
2144 turned off, possible causing trouble later; (2) The flag was not being
2145 set at all for the header_verify test, causing "group"-style headers to
2146 be rejected. I have now set it in this case, and also caused header_
2147 verify to ignore an empty address taken from a group. While doing this, I
2148 came across some other cases where the code for allowing group syntax
2149 while scanning a header line wasn't quite right (mostly, not resetting
2150 the flag correctly in the right place). These bugs could have caused
2151 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2153PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2154 with the "reply" argument non-NULL. The code, however (which originally
2155 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2156 but it didn't always do it. This confused somebody who was copying the
2157 code for some other use. I have removed all the tests.
2158
411ef850
PH
2159PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2160 feature that was used to support insecure browsers during the U.S. crypto
2161 embargo. It requires special client support, and Exim is probably the
2162 only MTA that supported it -- and would never use it because real RSA is
2163 always available. This code has been removed, because it had the bad
2164 effect of slowing Exim down by computing (never used) parameters for the
2165 RSA_EXPORT functionality.
2166
7befa435
PH
2167PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2168 authenticator to fail if there's a tab character in the incoming data
2169 (there should never be unless someone is messing about, as it's supposed
2170 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2171 if the connection is using TLS or if the remote IP is the same as the
2172 local IP, and the "valid-client-cert option" if a client certificate has
2173 been verified.

PH
2204
2205PH/30 Exim was sometimes attempting to deliver messages that had suffered
2206 address errors (4xx response to RCPT) over the same connection as other
2207 messages routed to the same hosts. Such deliveries are always "forced",
2208 so retry times are not inspected. This resulted in far too many retries
2209 for the affected addresses. The effect occurred only when there were more
2210 hosts than the hosts_max_try setting in the smtp transport when it had
2211 the 4xx errors. Those hosts that it had tried were not added to the list
2212 of hosts for which the message was waiting, so if all were tried, there
2213 was no problem. Two fixes have been applied:
2214
2215 (i) If there are any address or message errors in an SMTP delivery, none
2216 of the hosts (tried or untried) are now added to the list of hosts
2217 for which the message is waiting, so the message should not be a
2218 candidate for sending over the same connection that was used for a
2219 successful delivery of some other message. This seems entirely
2220 reasonable: after all the message is NOT "waiting for some host".
2221 This is so "obvious" that I'm not sure why it wasn't done
2222 previously. Hope I haven't missed anything, but it can't do any
2223 harm, as the worst effect is to miss an optimization.
2224
2225 (ii) If, despite (i), such a delivery is accidentally attempted, the
2226 routing retry time is respected, so at least it doesn't keep
2227 hammering the server.

520de300
PH
2242PH/35 The error "getsockname() failed: connection reset by peer" was being
2243 written to the panic log as well as the main log, but it isn't really
2244 panic-worthy as it just means the connection died rather early on. I have
2245 removed the panic log writing for the ECONNRESET error when getsockname()
2246 fails.
2247
48c7f9e2
PH
2248PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2249 runs only) independently of the message's sender address. This meant
2250 that, if the 4xx error was in fact related to the sender, a different
2251 message to the same recipient with a different sender could confuse
2252 things. In particualar, this can happen when sending to a greylisting
2253 server, but other circumstances could also provoke similar problems.
2254 I have changed the default so that the retry time for these errors is now
2255 based a combination of the sender and recipient addresses. This change
2256 can be overridden by setting address_retry_include_sender=false in the
2257 smtp transport.

2528 tcp-wrappers gives "deny", whereas what one would like would be some
2529 kind of temporary error. A kludge has been added to help with this.
2530 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2531 554 error is used if errno is still zero or contains ENOENT (which occurs
2532 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2573 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2618 autoreply, Exim could try to deliver to a non-existent relative file

2654 Instead, it always explicitly searches for A/AAAA records. This avoids
2655 major problems that occur when a DNS server includes only records of one
2656 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2657 fixed another bug: if SRV records were looked up and the corresponding
2658 address records were *not* found in the additional section, the port
2659 values from the SRV records were lost.

2669PH/19 When calculating a retry time, Exim used to measure the "time since
2670 failure" by looking at the "first failed" field in the retry record. Now
2671 it does not use this if it is later than than the arrival time of the
2672 message. Instead it uses the arrival time. This makes for better
2673 behaviour in cases where some deliveries succeed, thus re-setting the
2674 "first failed" field. An example is a quota failure for a huge message
2675 when small messages continue to be delivered. Without this change, the
2676 "time since failure" will always be short, possible causing more frequent
2677 delivery attempts for the huge message than are intended.

PH
2774PH/42 The content-scanning code uses fopen() to create files in which to put
2775 message data. Previously it was not paying any attention to the mode of
2776 the files. Exim runs with umask(0) because the rest of the code creates
2777 files with open(), and sets the required mode explicitly. Thus, these
2778 files were ending up world-writeable. This was not a big issue, because,
2779 being within the spool directory, they were not world-accessible. I have
2780 created a function called modefopen, which takes an additional mode
2781 argument. It sets umask(777), creates the file, chmods it to the required
2782 mode, then resets the umask. All the relevant calls to fopen() in the
2783 content scanning code have been changed to use this function.

2791PH/45 When the plaintext authenticator is running as a client, the server's
2792 challenges are checked to ensure they are valid base64 strings. By
2793 default, the authentication attempt is cancelled if an invalid string is
2794 received. Setting client_ignore_invalid_base64 true ignores these errors.
2795 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2796 they are received. Thus, the responses can be made to depend on the
2797 challenges. If an invalid string is ignored, an empty string is placed in
2798 the variable.

PH
2818PH/52 Two bugs concerned with error handling when the smtp transport is
2819 used in LMTP mode:
2820
2821 (i) Exim was not creating retry information for temporary errors given
2822 for individual recipients after the DATA command when the smtp transport
2823 was used in LMTP mode. This meant that they could be retried too
2824 frequently, and not timed out correctly.
2825
2826 (ii) Exim was setting the flag that allows error details to be returned
2827 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2828 recipients that were returned after the DATA command.
2829
2830PH/53 This is related to PH/52, but is more general: for any failing address,
2831 when detailed error information was permitted to be returned to the
2832 sender, but the error was temporary, then after the final timeout, only
2833 "retry timeout exceeded" was returned. Now it returns the full error as
2834 well as "retry timeout exceeded".

2890PH/68 The bounce_return_message and bounce_return_body options were not being

2892 In particular, this applied to messages rejected by the ACL. This bug has
2893 been fixed. However, if bounce_return_message is true and bounce_return_
2894 body is false, the headers that are returned for a non-SMTP message
2895 include only those that have been read before the error was detected.

2898PH/69 The HTML version of the specification is now built in a directory called

PH
2904PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2905 function verify_get_ident() calls ip_connect() to connect a socket, but
2906 if the "connect()" function timed out, ip_connect() used to close the
2907 socket. However, verify_get_ident() also closes the socket later, and in
2908 between Exim writes to the log, which may get opened at this point. When
2909 the socket was closed in ip_connect(), the log could get the same file
2910 descriptor number as the socket. This naturally causes chaos. The fix is
2911 not to close the socket in ip_connect(); the socket should be closed by
2912 the function that creates it. There was only one place in the code where
2913 this was missing, in the iplookup router, which I don't think anybody now
2914 uses, but I've fixed it anyway.

2933PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2934
2935 (1) Generate an error if the third argument for the ${prvs expansion is
2936 not a single digit.
2937
2938 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2939 string.
2940
2941 (3) Reset the variables that are obtained from the first argument of
2942 ${prvscheck and used in the second argument before leaving the code,
2943 because their memory is reclaimed, so using them afterwards may do
2944 silly things.
2945
2946 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2947 one (it's much easier than Tom thought :-).
2948
2949 (5) Because of (4), we can now allow for the use of $prvscheck_result
2950 inside the third argument.

2961
2962 => >A.N.Other <ano@some.domain> <original@ddress> ...
2963
2964 This has been changed so that it extracts the operative address. There
2965 may be more than one such address. If so, they are comma-separated, like

PH
2970PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2971 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2972 not being looked up in the rDNS to get a host name, Exim was showing the
2973 IP address twice in Received: lines, even though the IP addresses were
2974 identical. For example:
2975
2976 Received: from [1.2.3.4] (helo=[1.2.3.4])
2977
2978 However, if the real host name was known, it was omitting the HELO data
2979 if it matched the actual IP address. This has been tidied up so that it
2980 doesn't show the same IP address twice.

2982PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
3006PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3007 Electronic Mail") by including:
3008
3009 Auto-submitted: auto-generated
3010
3011 in the messages that it generates (bounce messages and others, such as
3012 warnings). In the case of bounce messages for non-SMTP mesages, there was
3013 also a typo: it was using "Auto_submitted" (underscore instead of
3014 hyphen). Since every message generated by Exim is necessarily in response
3015 to another message, thes have all been changed to:
3016
3017 Auto-Submitted: auto-replied
3018
3019 in accordance with these statements in the RFC:
3020
3021 The auto-replied keyword:
3022
3023 - SHOULD be used on messages sent in direct response to another
3024 message by an automatic process,
3025

3069PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

3071 the IP address, check_host() was doing a simple string comparison with
3072 addresses acquired from the DNS when checking that the found name did
3073 have the original IP as one of its addresses. Since any found IPv6
3074 addresses are likely to be in abbreviated form, the comparison could
3075 fail. Luckily, there already exists a function for doing the comparison
3076 by converting both addresses to binary, so now that is used instead of
3077 the text comparison.

3156PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to

3159 the end of the subprocess.

3161PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3162 only if the host matched helo_try_verify_hosts, which caused the
3163 verification to occur when the EHLO/HELO command was issued. The ACL just
3164 tested the remembered result. Now, if a previous verification attempt has
3165 not happened, "verify = helo" does it there and then.

3194PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3195 authentication with radiusclient 0.4.9:
3196
3197 - Error returned from rc_read_config was caught wrongly
3198 - Username/password not passed on to radius server due to wrong length.
3199
3200 The presumption is that some radiusclient API changes for 4.51/PH/17
3201 were not taken care of correctly. The code is still untested by me (my
3202 Linux distribution still has 0.3.2 of radiusclient), but it was
3203 contributed by a Radius user.

3218PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3256 From: header, and the sender address was obtained from -f or from an SMTP
3257 MAIL command, and the trusted user did not use -F to supply a sender
3258 name, $originator_name was incorrectly used when constructing a From:
3259 header. Furthermore, $originator_name was used for submission mode
3260 messages from external hosts without From: headers in a similar way,
3261 which is clearly wrong.
