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.
20

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.

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.
56

JH
57JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
58

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

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.

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
e161710d
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.
111
abe1010c
JH
112JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
113 for DKIM processing.

f0989ec0
JH
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}.
cee5f132 122
8c5d388a
JH
123JH/27 Move Internationalisation support from Experimental to mainline, enabled
124 for a build by defining SUPPORT_I18N

135 cached by the daemon.
136
de78e2d5
JH
137JH/32 Move Redis support from Experimental to mainline, enabled for a build
138 by defining LOOKUP_REDIS. The libhiredis library is required.
139
379ba7d0
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.

df3def24 177
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.
181
59eaad2b
JH
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.
185
f9334a28
JH
186JH/45 Fix cutthrough, when connection not opened by verify and target hard-
187 rejects a recipient: pass the reject to the originator.
188
dc8091e7
JH
189JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
190 Many were false-positives and ignorable, but it's worth fixing the
191 former class.

JH
200JH/02 The smtp transport option "multi_domain" is now expanded.
201
ad07e9ad

202JH/03 The smtp transport now requests PRDR by default, if the server offers
203 it.
204
01a4a5c5 205JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 206 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
207 can be used to disable this per-host. The build option
208 EXPERIMENTAL_CERTNAMES is withdrawn.
209
cb1d7830 210JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 211 default to the word "system" to access the system default CA bundle.

JH
212 For GnuTLS, only version 3.0.20 or later.
213
610ff438 214JH/06 Verification of the server certificate for a TLS connection is now tried

JH
215 (but not required) by default. The verification status is now logged by
216 default, for both outbound TLS and client-certificate supplying inbound
217 TLS connections
610ff438 218

220 sites use this now.
221
50dc7409
JH
222JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
223 Status Notification (bounce) messages are now MIME format per RFC 3464.
224 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
225 under the control of the dsn_advertise_hosts option, and routers may
226 have a dsn_lasthop option.
227
0f0c8159
JH
228JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
229 default, modifiable by a malware= option. The list separator for
23763898 230 the options can now be changed in the usual way. Bug 68.
4e71661f 231

234JH/11 The incoming_interface log option now also enables logging of the
235 local interface on delivery outgoing connections.
236
5032d1cf

244 Patch from Andrew Lewis.
245
fd4d8871 246JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 247 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
248 modifiers per server. Patch originally by <rommer@active.by>.
249
250JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
251 and remote servers. Remote servers can be IPv6 addresses, and
252 specify a port-range.
fd4d8871 253

JH
266JH/21 Support for the A6 type of dns record is withdrawn.
267
82c0c8ea
JH
268JH/22 Bug 608: The result of a QUIT or not-QUIT toplevel ACL now matters
269 rather than the verbs used.
270
b980ed83

JH
289JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
290 Normally benign, it bites when the pair was led to by a CNAME;
291 modern usage is to not canoicalize the domain to a CNAME target
292 (and we were inconsistent anyway for A-only vs AAAA+A).

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

325TL/02 The BSD's have an arc4random API. One of the functions to induce
326 adding randomness was arc4random_stir(), but it has been removed in

333TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
334 syntax errors in an expansion can be treated as a string instead of
335 logging or causing an error, due to the internal use of bool_lax
336 instead of bool when processing it.

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

357JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed

364JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
365 is EXPERIMENTAL_EVENT, the main-configuration and transport options
366 both become "event_action", the variables become $event_name, $event_data
aec45841 367 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
368 routers, transports and related events. The tls:cert event is now also
369 raised for inbound connections, if the main configuration event_action
370 option is defined.

428
429 When a message was received over SMTP with TLS, Exim failed to clear up
430 the incoming connection properly after forking off the child process to
431 deliver the message. In some situations the subsequent outgoing
432 delivery connection happened to have the same fd number as the incoming
433 connection previously had. Exim would try to use TLS and fail, logging
434 a "Bad file descriptor" error.

680TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
681
682 When a queue runner is handling a message, Exim first routes the
683 recipient addresses, during which it prunes them based on the retry
684 hints database. After that it attempts to deliver the message to
685 any remaining recipients. It then updates the hints database using
686 the retry rules.
687
688 So if a recipient address works intermittently, it can get repeatedly
689 deferred at routing time. The retry hints record remains fresh so the
690 address never reaches the final cutoff time.
691
692 This is a fairly common occurrence when a user is bumping up against
693 their storage quota. Exim had some logic in its local delivery code
694 to deal with this. However it did not apply to per-recipient defers
695 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
696
1ddeb334
TF
697 This change adds a proper retry rule check during routing so that the
698 final cutoff time is checked against the message's age. We only do
699 this check if there is an address retry record and there is not a
700 domain retry record; this implies that previous attempts to handle
701 the address had the retry_use_local_parts option turned on. We use
702 this as an approximation for the destination being like a local
703 delivery, as in LMTP.
67bd1ab3
TF
704
705 I suspect this new check makes the old local delivery cutoff check
706 redundant, but I have not verified this so I left the code in place.

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

1028TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1029 lock up or crash if it happened to be inside a call to libc when it
1030 got a SIGUSR1 from exiwhat.
1031
1032 The SIGUSR1 handler appends the current process status to the process
1033 log which is later printed by exiwhat. It used to use the general
1034 purpose logging code to do this, but several functions it calls are
1035 not safe for signals.
1036
1037 The new output code in the SIGUSR1 handler is specific to the process
1038 log, and simple enough that it's easy to inspect for signal safety.
1039 Removing some special cases also simplifies the general logging code.
1040 Removing the spurious timestamps from the process log simplifies
1041 exiwhat.

TF
1043TF/04 Improved ratelimit ACL condition.
1044
1045 The /noupdate option has been deprecated in favour of /readonly which
1046 has clearer semantics. The /leaky, /strict, and /readonly update modes
1047 are mutually exclusive. The update mode is no longer included in the
1048 database key; it just determines when the database is updated. (This
1049 means that when you upgrde Exim will forget old rate measurements.)
1050
1051 Exim now checks that the per_* options are used with an update mode that
1052 makes sense for the current ACL. For example, when Exim is processing a
1053 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1054 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1055 must specify per_mail/readonly. If you omit the update mode it defaults to
1056 /leaky where that makes sense (as before) or /readonly where required.
1057
1058 The /noupdate option is now undocumented but still supported for
1059 backwards compatibility. It is equivalent to /readonly except that in
1060 ACLs where /readonly is required you may specify /leaky/noupdate or
1061 /strict/noupdate which are treated the same as /readonly.
1062
1063 A useful new feature is the /count= option. This is a generalization
1064 of the per_byte option, so that you can measure the throughput of other
1065 aggregate values. For example, the per_byte option is now equivalent
1066 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1067
1068 The per_rcpt option has been generalized using the /count= mechanism
1069 (though it's more complicated than the per_byte equivalence). When it is
1070 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1071 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1072 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1073 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1074 Note that using per_rcpt with a non-readonly update mode in more than
1075 one ACL will cause the recipients to be double-counted. (The per_mail
1076 and per_byte options don't have this problem.)
1077
1078 The handling of very low rates has changed slightly. If the computed rate
1079 is less than the event's count (usually one) then this event is the first
1080 after a long gap. In this case the rate is set to the same as this event's
1081 count, so that the first message of a spam run is counted properly.
1082
1083 The major new feature is a mechanism for counting the rate of unique
1084 events. The new per_addr option counts the number of different
1085 recipients that someone has sent messages to in the last time period. It
1086 behaves like per_rcpt if all the recipient addresses are different, but
1087 duplicate recipient addresses do not increase the measured rate. Like
1088 the /count= option this is a general mechanism, so the per_addr option
1089 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1090 example, measure the rate that a client uses different sender addresses
1091 with the options per_mail/unique=$sender_address. There are further
1092 details in the main documentation.

1642 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1643 were called 'true' and it seems that C99 defines that as a reserved
1644 keyword to be used with 'bool' variable types. That means you could
1645 not include C99-style headers which use bools without triggering
1646 build errors in sieve.c.

1661Exim version 4.68
1662-----------------
1663
1664PH/01 Another patch from the Sieve maintainer.
1665
6a3bceb1
PH
1666PH/02 When an IPv6 address is converted to a string for single-key lookup
1667 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1668 dots are used instead of colons so that keys in lsearch files need not
1669 contain colons. This was done some time before quoting was made available
1670 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1671 (notated using the quote facility) so as to distinguish them from IPv4
1672 keys. This meant that lookups for IP addresses in host lists did not work
1673 for iplsearch lookups.
1674
1675 This has been fixed by arranging for IPv6 addresses to be expressed with
1676 colons if the lookup type is iplsearch. This is not incompatible, because
1677 previously such lookups could never work.
1678
1679 The situation is now rather anomolous, since one *can* have colons in
1680 ordinary lsearch keys. However, making the change in all cases is
1681 incompatible and would probably break a number of configurations.
1682

MH
1686MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1687 conversion specification without a maximum field width, thereby enabling
1688 a rogue spamd server to cause a buffer overflow. While nobody in their
1689 right mind would setup Exim to query an untrusted spamd server, an
1690 attacker that gains access to a server running spamd could potentially
1691 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1696MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1697 a directory entry by the name of the lookup key. Previously, if a
1698 symlink pointed to a non-existing file or a file in a directory that
1699 Exim lacked permissions to read, a lookup for a key matching that
1700 symlink would fail. Now it is enough that a matching directory entry
1701 exists, symlink or not. (Bugzilla 503.)

1778 if a client was not listed at all, or was listed with a value other than
1779 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1780 the condition was not true (as it should be), so access was not denied.

PH
1884PH/29 SMTP synchronization checks are implemented when a command is read -
1885 there is a check that no more input is waiting when there shouldn't be
1886 any. However, for some commands, a delay in an ACL can mean that it is
1887 some time before the response is written. In this time, more input might
1888 arrive, invalidly. So now there are extra checks after an ACL has run for
1889 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1890 pipelining has not been advertised.

PH
1902PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1903 Exim which did not show up earlier: it was assuming that a call to
1904 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1905 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1906 was a macro that became an assignment, so it seemed to work. This has
1907 changed to a proper function call with a void return, hence the compile
1908 error. Exim's code has been fixed.

1944 message are rejected with the same error (e.g. no authentication or bad
1945 sender address), and a DATA command is nevertheless sent (as can happen
1946 with PIPELINING or a stupid MUA), the error message that was given to the
1947 RCPT commands is included in the rejection of the DATA command. This is
1948 intended to be helpful for MUAs that show only the final error to their
1949 users.

58eb016e 1963PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1964 the response to the final '.' that terminates a message, but only in the
1965 case where the client has not sent further data following the '.'
1966 (unfortunately, this is allowed). However, in many cases there won't be
1967 any further data because there won't be any more messages to send. A call
1968 to select() can be used: if it shows that the input is "ready", there is
1969 either input waiting, or the socket has been closed. An attempt to read
1970 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1971 would have sent an OK response which the client would never have see.

1981
1982PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1983 fixed by 4.65/MH/01 (is this a record?) are fixed:
1984
1985 (i) An empty string was always treated as zero by the numeric comparison
1986 operators. This behaviour has been restored.
1987
1988 (ii) It is documented that the numeric comparison operators always treat
1989 their arguments as decimal numbers. This was broken in that numbers
1990 starting with 0 were being interpreted as octal.
1991
1992 While fixing these problems I realized that there was another issue that
1993 hadn't been noticed. Values of message_size_limit (both the global option
1994 and the transport option) were treated as octal if they started with 0.
1995 The documentation was vague. These values are now always treated as
1996 decimal, and I will make that clear in the documentation.

2010PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

2012 is held in a short int, deliveries were likely to be lost. As such a
2013 large number of recipients for a single message is ridiculous
2014 (performance will be very, very poor), I have chosen to impose a limit
2015 rather than extend the field.

2021TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2022 leftover -K file (the existence of which was triggered by #402).

2031TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
2040PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2041 callout verification, Exim cached a "reject" for the entire domain. This
2042 is correct for most verifications, but it is not correct for a recipient
2043 verification with use_sender or use_postmaster set, because in that case
2044 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2045 case of MAIL FROM:<> rejection from other early rejections (e.g.
2046 rejection of HELO). When verifying a recipient using a non-null MAIL
2047 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2048 Whatever the result of the callout, the value of the domain cache is
2049 left unchanged (for any other kind of callout, getting as far as trying
2050 RCPT means that the domain itself is ok).

2084PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2086 probably the interface on which it is arriving) and not to the outgoing
2087 callout (which could be using a different interface). This has been
2088 changed to use the value of the helo_data option from the smtp transport
2089 instead - this is what is used when a message is actually being sent. If
2090 there is no remote transport (possible with a router that sets up host
2091 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2095 (a) The code assumed that strncpy() returns a negative number on buffer
2096 overflow, which isn't the case. Replaced with Exim's string_format()
2097 function.
2098 (b) There were several signed/unsigned issues. I just did the minimum
2099 hacking in of casts. There is scope for a larger refactoring.
2100 (c) The code used strcasecmp() which is not a standard C function.
2101 Replaced with Exim's strcmpic() function.
2102 (d) The code set only $1; it now sets $auth1 as well.
2103 (e) A simple test gave the error "authentication client didn't specify
2104 service in request". It would seem that Dovecot has changed its
2105 interface. Fortunately there's a specification; I followed it and
2106 changed what the client sends and it appears to be working now.

2112 address A is aliased to B and C, where B exists and C does not. Without
2113 -v the output is "A verified" because verification stops after a
2114 successful redirection if more than one address is generated. However,
2115 with -v the child addresses are also verified. Exim was outputting "A
2116 failed to verify" and then showing the successful verification for C,
2117 with its parentage. It now outputs "B failed to verify", showing B's
2118 parentage before showing the successful verification of C.

2123
322050c2
PH
2124PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2125 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2126 they consult the DNS. I had assumed they would set it the way they
2127 wanted; and indeed my experiments on Linux seem to show that in some
2128 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2129 To be on the safe side, however, I have now made the interface to
2130 host_find_byname() similar to host_find_bydns(), with an argument
2131 containing the DNS resolver options. The host_find_byname() function now
2132 sets these options at its start, just as host_find_bydns() does. The smtp
2133 transport options dns_qualify_single and dns_search_parents are passed to
2134 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2135 of host_find_byname() use the default settings of RES_DEFNAMES
2136 (qualify_single) but not RES_DNSRCH (search_parents).

2138PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2139 spool_read_header() do less string testing, by means of a preliminary
2140 switch on the second character of optional "-foo" lines. (This is
2141 overdue, caused by the large number of possibilities that now exist.
2142 Originally there were few.) While I was there, I also converted the
2143 str(n)cmp tests so they don't re-test the leading "-" and the first
2144 character, in the hope this might squeeze out yet more improvement.

2146PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2147 flag allowing group syntax was set by the header_syntax check but not
2148 turned off, possible causing trouble later; (2) The flag was not being
2149 set at all for the header_verify test, causing "group"-style headers to
2150 be rejected. I have now set it in this case, and also caused header_
2151 verify to ignore an empty address taken from a group. While doing this, I
2152 came across some other cases where the code for allowing group syntax
2153 while scanning a header line wasn't quite right (mostly, not resetting
2154 the flag correctly in the right place). These bugs could have caused
2155 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2157PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2158 with the "reply" argument non-NULL. The code, however (which originally
2159 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2160 but it didn't always do it. This confused somebody who was copying the
2161 code for some other use. I have removed all the tests.

PH
2163PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2164 feature that was used to support insecure browsers during the U.S. crypto
2165 embargo. It requires special client support, and Exim is probably the
2166 only MTA that supported it -- and would never use it because real RSA is
2167 always available. This code has been removed, because it had the bad
2168 effect of slowing Exim down by computing (never used) parameters for the
2169 RSA_EXPORT functionality.

PH
2171PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2172 authenticator to fail if there's a tab character in the incoming data
2173 (there should never be unless someone is messing about, as it's supposed
2174 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2175 if the connection is using TLS or if the remote IP is the same as the
2176 local IP, and the "valid-client-cert option" if a client certificate has
2177 been verified.

2208
2209PH/30 Exim was sometimes attempting to deliver messages that had suffered
2210 address errors (4xx response to RCPT) over the same connection as other
2211 messages routed to the same hosts. Such deliveries are always "forced",
2212 so retry times are not inspected. This resulted in far too many retries
2213 for the affected addresses. The effect occurred only when there were more
2214 hosts than the hosts_max_try setting in the smtp transport when it had
2215 the 4xx errors. Those hosts that it had tried were not added to the list
2216 of hosts for which the message was waiting, so if all were tried, there
2217 was no problem. Two fixes have been applied:
2218
2219 (i) If there are any address or message errors in an SMTP delivery, none
2220 of the hosts (tried or untried) are now added to the list of hosts
2221 for which the message is waiting, so the message should not be a
2222 candidate for sending over the same connection that was used for a
2223 successful delivery of some other message. This seems entirely
2224 reasonable: after all the message is NOT "waiting for some host".
2225 This is so "obvious" that I'm not sure why it wasn't done
2226 previously. Hope I haven't missed anything, but it can't do any
2227 harm, as the worst effect is to miss an optimization.
2228
2229 (ii) If, despite (i), such a delivery is accidentally attempted, the
2230 routing retry time is respected, so at least it doesn't keep
2231 hammering the server.

PH
2246PH/35 The error "getsockname() failed: connection reset by peer" was being
2247 written to the panic log as well as the main log, but it isn't really
2248 panic-worthy as it just means the connection died rather early on. I have
2249 removed the panic log writing for the ECONNRESET error when getsockname()
2250 fails.
2251
48c7f9e2
PH
2252PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2253 runs only) independently of the message's sender address. This meant
2254 that, if the 4xx error was in fact related to the sender, a different
2255 message to the same recipient with a different sender could confuse
2256 things. In particualar, this can happen when sending to a greylisting
2257 server, but other circumstances could also provoke similar problems.
2258 I have changed the default so that the retry time for these errors is now
2259 based a combination of the sender and recipient addresses. This change
2260 can be overridden by setting address_retry_include_sender=false in the
2261 smtp transport.

2529PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2530 "Deny" causes Exim to reject the incoming connection with a 554 error.
2531 Unfortunately, if there is a major crisis, such as a disk failure,
2532 tcp-wrappers gives "deny", whereas what one would like would be some
2533 kind of temporary error. A kludge has been added to help with this.
2534 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2535 554 error is used if errno is still zero or contains ENOENT (which occurs
2536 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2537 451 error is used.

2559PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

2562 used only to exclude .Trash (or whatever) when the size of the mailbox
2563 was calculated. There was no check that a delivery was happening into an

2573PH/01 The code for finding all the local interface addresses on a FreeBSD
2574 system running IPv6 was broken. This may well have applied to all BSD
2575 systems, as well as to others that have similar system calls. The broken
2576 code found IPv4 interfaces correctly, but gave incorrect values for the
2577 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2578 that it would not match correctly against @[] and not recognize the IPv6
2579 addresses as local.

2620 syntactically invalid From: or Reply-to: line, and a filter used this to
2621 generate an autoreply, and therefore failed to obtain an address for the
2622 autoreply, Exim could try to deliver to a non-existent relative file
2623 name, causing unrelated and misleading errors. What now happens is that
2624 it logs this as a hard delivery error, but does not attempt to create a

2642 non-existent - all you got was a failure to exec. I have made two
2643 changes:
2644
2645 (a) Failures to set uid/gid, the current directory, or a process leader
2646 in a subprocess such as that created by queryprogram now generate
2647 suitable debugging ouput when -d is set.
2648
2649 (b) The queryprogram router detects when it is not running as root,
2650 outputs suitable debugging information if -d is set, and then runs
2651 the subprocess without attempting to change uid/gid.

2656PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2657 additional section of a DNS packet that returns MX or SRV records.
2658 Instead, it always explicitly searches for A/AAAA records. This avoids
2659 major problems that occur when a DNS server includes only records of one
2660 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2661 fixed another bug: if SRV records were looked up and the corresponding
2662 address records were *not* found in the additional section, the port
2663 values from the SRV records were lost.

ea49d0e1
PH
2665PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2672
727071f8
PH
2673PH/19 When calculating a retry time, Exim used to measure the "time since
2674 failure" by looking at the "first failed" field in the retry record. Now
2675 it does not use this if it is later than than the arrival time of the
2676 message. Instead it uses the arrival time. This makes for better
2677 behaviour in cases where some deliveries succeed, thus re-setting the
2678 "first failed" field. An example is a quota failure for a huge message
2679 when small messages continue to be delivered. Without this change, the
2680 "time since failure" will always be short, possible causing more frequent
2681 delivery attempts for the huge message than are intended.

PH
2778PH/42 The content-scanning code uses fopen() to create files in which to put
2779 message data. Previously it was not paying any attention to the mode of
2780 the files. Exim runs with umask(0) because the rest of the code creates
2781 files with open(), and sets the required mode explicitly. Thus, these
2782 files were ending up world-writeable. This was not a big issue, because,
2783 being within the spool directory, they were not world-accessible. I have
2784 created a function called modefopen, which takes an additional mode
2785 argument. It sets umask(777), creates the file, chmods it to the required
2786 mode, then resets the umask. All the relevant calls to fopen() in the
2787 content scanning code have been changed to use this function.

2799 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2822PH/52 Two bugs concerned with error handling when the smtp transport is
2823 used in LMTP mode:
2824
2825 (i) Exim was not creating retry information for temporary errors given
2826 for individual recipients after the DATA command when the smtp transport
2827 was used in LMTP mode. This meant that they could be retried too
2828 frequently, and not timed out correctly.
2829
2830 (ii) Exim was setting the flag that allows error details to be returned
2831 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2832 recipients that were returned after the DATA command.
2833
2834PH/53 This is related to PH/52, but is more general: for any failing address,
2835 when detailed error information was permitted to be returned to the
2836 sender, but the error was temporary, then after the final timeout, only
2837 "retry timeout exceeded" was returned. Now it returns the full error as

2908PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2909 function verify_get_ident() calls ip_connect() to connect a socket, but
2910 if the "connect()" function timed out, ip_connect() used to close the
2911 socket. However, verify_get_ident() also closes the socket later, and in
2912 between Exim writes to the log, which may get opened at this point. When
2913 the socket was closed in ip_connect(), the log could get the same file
2914 descriptor number as the socket. This naturally causes chaos. The fix is
2915 not to close the socket in ip_connect(); the socket should be closed by
2916 the function that creates it. There was only one place in the code where
2917 this was missing, in the iplookup router, which I don't think anybody now
2918 uses, but I've fixed it anyway.

2942 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2944
2945 (3) Reset the variables that are obtained from the first argument of
2946 ${prvscheck and used in the second argument before leaving the code,
2947 because their memory is reclaimed, so using them afterwards may do
2948 silly things.
2949
2950 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2951 one (it's much easier than Tom thought :-).

2975 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2976 not being looked up in the rDNS to get a host name, Exim was showing the
2977 IP address twice in Received: lines, even though the IP addresses were
2978 identical. For example:
2979
2980 Received: from [1.2.3.4] (helo=[1.2.3.4])
2981
2982 However, if the real host name was known, it was omitting the HELO data
2983 if it matched the actual IP address. This has been tidied up so that it
2984 doesn't show the same IP address twice.

3076 addresses acquired from the DNS when checking that the found name did
3077 have the original IP as one of its addresses. Since any found IPv6
3078 addresses are likely to be in abbreviated form, the comparison could
3079 fail. Luckily, there already exists a function for doing the comparison
3080 by converting both addresses to binary, so now that is used instead of
3081 the text comparison.

3160PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to

3163 the end of the subprocess.

3165PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3166 only if the host matched helo_try_verify_hosts, which caused the
3167 verification to occur when the EHLO/HELO command was issued. The ACL just
3168 tested the remembered result. Now, if a previous verification attempt has
3169 not happened, "verify = helo" does it there and then.

3198PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3199 authentication with radiusclient 0.4.9:
3200
3201 - Error returned from rc_read_config was caught wrongly
3202 - Username/password not passed on to radius server due to wrong length.
3203
3204 The presumption is that some radiusclient API changes for 4.51/PH/17
3205 were not taken care of correctly. The code is still untested by me (my
3206 Linux distribution still has 0.3.2 of radiusclient), but it was
3207 contributed by a Radius user.

3222PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3259PH/36 When a locally submitted message by a trusted user did not contain a
3260 From: header, and the sender address was obtained from -f or from an SMTP
3261 MAIL command, and the trusted user did not use -F to supply a sender
3262 name, $originator_name was incorrectly used when constructing a From:
3263 header. Furthermore, $originator_name was used for submission mode
3264 messages from external hosts without From: headers in a similar way,
3265 which is clearly wrong.
