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.

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.

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.

JH
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.
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.

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.

112JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
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}.

135 cached by the daemon.

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

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.

184Exim version 4.86
185-----------------
186JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
187 expanded.

JH
189JH/02 The smtp transport option "multi_domain" is now expanded.
190
ad07e9ad
JH
191JH/03 The smtp transport now requests PRDR by default, if the server offers
192 it.
193
01a4a5c5 194JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 195 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
196 can be used to disable this per-host. The build option
197 EXPERIMENTAL_CERTNAMES is withdrawn.
198
cb1d7830 199JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 200 default to the word "system" to access the system default CA bundle.

JH
201 For GnuTLS, only version 3.0.20 or later.
202
610ff438 203JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
204 (but not required) by default. The verification status is now logged by
205 default, for both outbound TLS and client-certificate supplying inbound
206 TLS connections
610ff438 207

209 sites use this now.
210
50dc7409
JH
211JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
212 Status Notification (bounce) messages are now MIME format per RFC 3464.
213 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
214 under the control of the dsn_advertise_hosts option, and routers may
215 have a dsn_lasthop option.
216
0f0c8159
JH
217JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
218 default, modifiable by a malware= option. The list separator for

233 Patch from Andrew Lewis.
234
fd4d8871 235JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 236 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
237 modifiers per server. Patch originally by <rommer@active.by>.
238
239JH/16 The spamd_address main option now supports a mixed list of local
2aad5761

JH
278JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
279 Normally benign, it bites when the pair was led to by a CNAME;
280 modern usage is to not canoicalize the domain to a CNAME target
281 (and we were inconsistent anyway for A-only vs AAAA+A).

304Exim version 4.85
305-----------------
306TL/01 When running the test suite, the README says that variables such as
307 no_msglog_check are global and can be placed anywhere in a specific
308 test's script, however it was observed that placement needed to be near
309 the beginning for it to behave that way. Changed the runtest perl
310 script to read through the entire script once to detect and set these
311 variables, reset to the beginning of the script, and then run through
312 the script parsing/test process like normal.

314TL/02 The BSD's have an arc4random API. One of the functions to induce
315 adding randomness was arc4random_stir(), but it has been removed in

317 function when detected.

TL
322TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
323 syntax errors in an expansion can be treated as a string instead of
324 logging or causing an error, due to the internal use of bool_lax
325 instead of bool when processing it.

WB
339JH/05 Fix results-pipe from transport process. Several recipients, combined
340 with certificate use, exposed issues where response data items split
341 over buffer boundaries were not parsed properly. This eventually
342 resulted in duplicates being sent. This issue only became common enough
343 to notice due to the introduction of conection certificate information,
344 the item size being so much larger. Found and fixed by Wolfgang Breyha.

8bc732e8
JH
346JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed

JH
353JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
354 is EXPERIMENTAL_EVENT, the main-configuration and transport options
355 both become "event_action", the variables become $event_name, $event_data
aec45841 356 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
357 routers, transports and related events. The tls:cert event is now also
358 raised for inbound connections, if the main configuration event_action
359 option is defined.

669TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
670
671 When a queue runner is handling a message, Exim first routes the
672 recipient addresses, during which it prunes them based on the retry
673 hints database. After that it attempts to deliver the message to
674 any remaining recipients. It then updates the hints database using
675 the retry rules.
676
677 So if a recipient address works intermittently, it can get repeatedly
678 deferred at routing time. The retry hints record remains fresh so the
679 address never reaches the final cutoff time.
680
681 This is a fairly common occurrence when a user is bumping up against
682 their storage quota. Exim had some logic in its local delivery code
683 to deal with this. However it did not apply to per-recipient defers
684 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
685
1ddeb334
TF
686 This change adds a proper retry rule check during routing so that the
687 final cutoff time is checked against the message's age. We only do
688 this check if there is an address retry record and there is not a
689 domain retry record; this implies that previous attempts to handle
690 the address had the retry_use_local_parts option turned on. We use
691 this as an approximation for the destination being like a local
692 delivery, as in LMTP.
67bd1ab3
TF
693
694 I suspect this new check makes the old local delivery cutoff check
695 redundant, but I have not verified this so I left the code in place.

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

1017TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1018 lock up or crash if it happened to be inside a call to libc when it
1019 got a SIGUSR1 from exiwhat.
1020
1021 The SIGUSR1 handler appends the current process status to the process
1022 log which is later printed by exiwhat. It used to use the general
1023 purpose logging code to do this, but several functions it calls are
1024 not safe for signals.
1025
1026 The new output code in the SIGUSR1 handler is specific to the process
1027 log, and simple enough that it's easy to inspect for signal safety.
1028 Removing some special cases also simplifies the general logging code.
1029 Removing the spurious timestamps from the process log simplifies
1030 exiwhat.

TF
1032TF/04 Improved ratelimit ACL condition.
1033
1034 The /noupdate option has been deprecated in favour of /readonly which
1035 has clearer semantics. The /leaky, /strict, and /readonly update modes
1036 are mutually exclusive. The update mode is no longer included in the
1037 database key; it just determines when the database is updated. (This
1038 means that when you upgrde Exim will forget old rate measurements.)
1039
1040 Exim now checks that the per_* options are used with an update mode that
1041 makes sense for the current ACL. For example, when Exim is processing a
1042 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1043 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1044 must specify per_mail/readonly. If you omit the update mode it defaults to
1045 /leaky where that makes sense (as before) or /readonly where required.
1046
1047 The /noupdate option is now undocumented but still supported for
1048 backwards compatibility. It is equivalent to /readonly except that in
1049 ACLs where /readonly is required you may specify /leaky/noupdate or
1050 /strict/noupdate which are treated the same as /readonly.
1051
1052 A useful new feature is the /count= option. This is a generalization
1053 of the per_byte option, so that you can measure the throughput of other
1054 aggregate values. For example, the per_byte option is now equivalent
1055 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1056
1057 The per_rcpt option has been generalized using the /count= mechanism
1058 (though it's more complicated than the per_byte equivalence). When it is
1059 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1060 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1061 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1062 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1063 Note that using per_rcpt with a non-readonly update mode in more than
1064 one ACL will cause the recipients to be double-counted. (The per_mail
1065 and per_byte options don't have this problem.)
1066
1067 The handling of very low rates has changed slightly. If the computed rate
1068 is less than the event's count (usually one) then this event is the first
1069 after a long gap. In this case the rate is set to the same as this event's
1070 count, so that the first message of a spam run is counted properly.
1071
1072 The major new feature is a mechanism for counting the rate of unique
1073 events. The new per_addr option counts the number of different
1074 recipients that someone has sent messages to in the last time period. It
1075 behaves like per_rcpt if all the recipient addresses are different, but
1076 duplicate recipient addresses do not increase the measured rate. Like
1077 the /count= option this is a general mechanism, so the per_addr option
1078 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1079 example, measure the rate that a client uses different sender addresses
1080 with the options per_mail/unique=$sender_address. There are further
1081 details in the main documentation.

1632 were called 'true' and it seems that C99 defines that as a reserved

1650Exim version 4.68
1651-----------------
1652
1653PH/01 Another patch from the Sieve maintainer.
1654
6a3bceb1
PH
1655PH/02 When an IPv6 address is converted to a string for single-key lookup
1656 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1657 dots are used instead of colons so that keys in lsearch files need not
1658 contain colons. This was done some time before quoting was made available
1659 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1660 (notated using the quote facility) so as to distinguish them from IPv4
1661 keys. This meant that lookups for IP addresses in host lists did not work
1662 for iplsearch lookups.
1663
1664 This has been fixed by arranging for IPv6 addresses to be expressed with
1665 colons if the lookup type is iplsearch. This is not incompatible, because
1666 previously such lookups could never work.
1667
1668 The situation is now rather anomolous, since one *can* have colons in
1669 ordinary lsearch keys. However, making the change in all cases is
1670 incompatible and would probably break a number of configurations.
1671

TK
1672TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
1673 version.
1674
0806a9c5
MH
1675MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1676 conversion specification without a maximum field width, thereby enabling
1677 a rogue spamd server to cause a buffer overflow. While nobody in their
1678 right mind would setup Exim to query an untrusted spamd server, an
1679 attacker that gains access to a server running spamd could potentially
1680 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1685MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1686 a directory entry by the name of the lookup key. Previously, if a
1687 symlink pointed to a non-existing file or a file in a directory that
1688 Exim lacked permissions to read, a lookup for a key matching that
1689 symlink would fail. Now it is enough that a matching directory entry
1690 exists, symlink or not. (Bugzilla 503.)

1763PH/02 In an ACL statement such as

1767 if a client was not listed at all, or was listed with a value other than
1768 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1769 the condition was not true (as it should be), so access was not denied.

PH
1873PH/29 SMTP synchronization checks are implemented when a command is read -
1874 there is a check that no more input is waiting when there shouldn't be
1875 any. However, for some commands, a delay in an ACL can mean that it is
1876 some time before the response is written. In this time, more input might
1877 arrive, invalidly. So now there are extra checks after an ACL has run for
1878 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1879 pipelining has not been advertised.

PH
1891PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1892 Exim which did not show up earlier: it was assuming that a call to
1893 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1894 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1895 was a macro that became an assignment, so it seemed to work. This has
1896 changed to a proper function call with a void return, hence the compile
1897 error. Exim's code has been fixed.

1928 started the daemon, but after a SIGHUP it used the Exim user (because it

1935 with PIPELINING or a stupid MUA), the error message that was given to the

58eb016e 1952PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1953 the response to the final '.' that terminates a message, but only in the
1954 case where the client has not sent further data following the '.'
1955 (unfortunately, this is allowed). However, in many cases there won't be
1956 any further data because there won't be any more messages to send. A call
1957 to select() can be used: if it shows that the input is "ready", there is
1958 either input waiting, or the socket has been closed. An attempt to read
1959 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1960 would have sent an OK response which the client would never have see.

1970
1971PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1972 fixed by 4.65/MH/01 (is this a record?) are fixed:
1973
1974 (i) An empty string was always treated as zero by the numeric comparison
1975 operators. This behaviour has been restored.
1976
1977 (ii) It is documented that the numeric comparison operators always treat
1978 their arguments as decimal numbers. This was broken in that numbers
1979 starting with 0 were being interpreted as octal.
1980
1981 While fixing these problems I realized that there was another issue that
1982 hadn't been noticed. Values of message_size_limit (both the global option
1983 and the transport option) were treated as octal if they started with 0.
1984 The documentation was vague. These values are now always treated as
1985 decimal, and I will make that clear in the documentation.

1999PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2000 child addresses, Exim now panics and dies. Previously, because the count
2001 is held in a short int, deliveries were likely to be lost. As such a
2002 large number of recipients for a single message is ridiculous
2003 (performance will be very, very poor), I have chosen to impose a limit
2004 rather than extend the field.

2010TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2011 leftover -K file (the existence of which was triggered by #402).
2012 While we were at it, introduced process PID as part of the -K

2014 these files.

2016TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2017 processing considerably. Previous code took too long for large mails,

2019
2020TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2021 in the DK code in transports.c. sendfile() is not really portable,

2024TF/01 In the add_headers option to the mail command in an Exim filter,

2027 in the field name.

PH
2029PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2030 callout verification, Exim cached a "reject" for the entire domain. This
2031 is correct for most verifications, but it is not correct for a recipient
2032 verification with use_sender or use_postmaster set, because in that case
2033 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2034 case of MAIL FROM:<> rejection from other early rejections (e.g.
2035 rejection of HELO). When verifying a recipient using a non-null MAIL
2036 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2037 Whatever the result of the callout, the value of the domain cache is
2038 left unchanged (for any other kind of callout, getting as far as trying
2039 RCPT means that the domain itself is ok).

2073PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2074 hostname. This is wrong, because it relates to the incoming message (and
2075 probably the interface on which it is arriving) and not to the outgoing
2076 callout (which could be using a different interface). This has been
2077 changed to use the value of the helo_data option from the smtp transport
2078 instead - this is what is used when a message is actually being sent. If
2079 there is no remote transport (possible with a router that sets up host
2080 addresses), $smtp_active_hostname is used.

7befa435 2083 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2084 (a) The code assumed that strncpy() returns a negative number on buffer
2085 overflow, which isn't the case. Replaced with Exim's string_format()
2086 function.
2087 (b) There were several signed/unsigned issues. I just did the minimum
2088 hacking in of casts. There is scope for a larger refactoring.
2089 (c) The code used strcasecmp() which is not a standard C function.
2090 Replaced with Exim's strcmpic() function.
2091 (d) The code set only $1; it now sets $auth1 as well.
2092 (e) A simple test gave the error "authentication client didn't specify
2093 service in request". It would seem that Dovecot has changed its
2094 interface. Fortunately there's a specification; I followed it and
2095 changed what the client sends and it appears to be working now.

2100PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2101 address A is aliased to B and C, where B exists and C does not. Without
2102 -v the output is "A verified" because verification stops after a
2103 successful redirection if more than one address is generated. However,
2104 with -v the child addresses are also verified. Exim was outputting "A
2105 failed to verify" and then showing the successful verification for C,
2106 with its parentage. It now outputs "B failed to verify", showing B's
2107 parentage before showing the successful verification of C.

2110 look up a TXT record in a specific list after matching in a combined
2111 list.
2112
322050c2
PH
2113PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2114 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2115 they consult the DNS. I had assumed they would set it the way they
2116 wanted; and indeed my experiments on Linux seem to show that in some
2117 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2118 To be on the safe side, however, I have now made the interface to
2119 host_find_byname() similar to host_find_bydns(), with an argument
2120 containing the DNS resolver options. The host_find_byname() function now
2121 sets these options at its start, just as host_find_bydns() does. The smtp
2122 transport options dns_qualify_single and dns_search_parents are passed to
2123 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2124 of host_find_byname() use the default settings of RES_DEFNAMES
2125 (qualify_single) but not RES_DNSRCH (search_parents).

2127PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2128 spool_read_header() do less string testing, by means of a preliminary
2129 switch on the second character of optional "-foo" lines. (This is
2130 overdue, caused by the large number of possibilities that now exist.
2131 Originally there were few.) While I was there, I also converted the
2132 str(n)cmp tests so they don't re-test the leading "-" and the first
2133 character, in the hope this might squeeze out yet more improvement.

PH
2135PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2136 flag allowing group syntax was set by the header_syntax check but not
2137 turned off, possible causing trouble later; (2) The flag was not being
2138 set at all for the header_verify test, causing "group"-style headers to
2139 be rejected. I have now set it in this case, and also caused header_
2140 verify to ignore an empty address taken from a group. While doing this, I
2141 came across some other cases where the code for allowing group syntax
2142 while scanning a header line wasn't quite right (mostly, not resetting
2143 the flag correctly in the right place). These bugs could have caused
2144 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2146PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2147 with the "reply" argument non-NULL. The code, however (which originally
2148 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2149 but it didn't always do it. This confused somebody who was copying the
2150 code for some other use. I have removed all the tests.

PH
2152PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2153 feature that was used to support insecure browsers during the U.S. crypto
2154 embargo. It requires special client support, and Exim is probably the
2155 only MTA that supported it -- and would never use it because real RSA is
2156 always available. This code has been removed, because it had the bad
2157 effect of slowing Exim down by computing (never used) parameters for the
2158 RSA_EXPORT functionality.

PH
2160PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2161 authenticator to fail if there's a tab character in the incoming data
2162 (there should never be unless someone is messing about, as it's supposed
2163 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2164 if the connection is using TLS or if the remote IP is the same as the
2165 local IP, and the "valid-client-cert option" if a client certificate has
2166 been verified.

2197
2198PH/30 Exim was sometimes attempting to deliver messages that had suffered
2199 address errors (4xx response to RCPT) over the same connection as other
2200 messages routed to the same hosts. Such deliveries are always "forced",
2201 so retry times are not inspected. This resulted in far too many retries
2202 for the affected addresses. The effect occurred only when there were more
2203 hosts than the hosts_max_try setting in the smtp transport when it had
2204 the 4xx errors. Those hosts that it had tried were not added to the list
2205 of hosts for which the message was waiting, so if all were tried, there
2206 was no problem. Two fixes have been applied:
2207
2208 (i) If there are any address or message errors in an SMTP delivery, none
2209 of the hosts (tried or untried) are now added to the list of hosts
2210 for which the message is waiting, so the message should not be a
2211 candidate for sending over the same connection that was used for a
2212 successful delivery of some other message. This seems entirely
2213 reasonable: after all the message is NOT "waiting for some host".
2214 This is so "obvious" that I'm not sure why it wasn't done
2215 previously. Hope I haven't missed anything, but it can't do any
2216 harm, as the worst effect is to miss an optimization.
2217
2218 (ii) If, despite (i), such a delivery is accidentally attempted, the
2219 routing retry time is respected, so at least it doesn't keep
2220 hammering the server.

PH
2235PH/35 The error "getsockname() failed: connection reset by peer" was being
2236 written to the panic log as well as the main log, but it isn't really
2237 panic-worthy as it just means the connection died rather early on. I have
2238 removed the panic log writing for the ECONNRESET error when getsockname()
2239 fails.
2240
48c7f9e2
PH
2241PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2242 runs only) independently of the message's sender address. This meant
2243 that, if the 4xx error was in fact related to the sender, a different
2244 message to the same recipient with a different sender could confuse
2245 things. In particualar, this can happen when sending to a greylisting
2246 server, but other circumstances could also provoke similar problems.
2247 I have changed the default so that the retry time for these errors is now
2248 based a combination of the sender and recipient addresses. This change
2249 can be overridden by setting address_retry_include_sender=false in the
2250 smtp transport.

2521 tcp-wrappers gives "deny", whereas what one would like would be some
2522 kind of temporary error. A kludge has been added to help with this.
2523 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2524 554 error is used if errno is still zero or contains ENOENT (which occurs
2525 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2565 code found IPv4 interfaces correctly, but gave incorrect values for the
2566 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2611 autoreply, Exim could try to deliver to a non-existent relative file

2636 suitable debugging ouput when -d is set.

2647 Instead, it always explicitly searches for A/AAAA records. This avoids
2648 major problems that occur when a DNS server includes only records of one
2649 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2650 fixed another bug: if SRV records were looked up and the corresponding
2651 address records were *not* found in the additional section, the port
2652 values from the SRV records were lost.

2654PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2662PH/19 When calculating a retry time, Exim used to measure the "time since
2663 failure" by looking at the "first failed" field in the retry record. Now
2664 it does not use this if it is later than than the arrival time of the
2665 message. Instead it uses the arrival time. This makes for better
2666 behaviour in cases where some deliveries succeed, thus re-setting the
2667 "first failed" field. An example is a quota failure for a huge message
2668 when small messages continue to be delivered. Without this change, the
2669 "time since failure" will always be short, possible causing more frequent
2670 delivery attempts for the huge message than are intended.

PH
2767PH/42 The content-scanning code uses fopen() to create files in which to put
2768 message data. Previously it was not paying any attention to the mode of
2769 the files. Exim runs with umask(0) because the rest of the code creates
2770 files with open(), and sets the required mode explicitly. Thus, these
2771 files were ending up world-writeable. This was not a big issue, because,
2772 being within the spool directory, they were not world-accessible. I have
2773 created a function called modefopen, which takes an additional mode
2774 argument. It sets umask(777), creates the file, chmods it to the required
2775 mode, then resets the umask. All the relevant calls to fopen() in the
2776 content scanning code have been changed to use this function.

2787 received. Setting client_ignore_invalid_base64 true ignores these errors.
2788 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2789 they are received. Thus, the responses can be made to depend on the

2811PH/52 Two bugs concerned with error handling when the smtp transport is
2812 used in LMTP mode:
2813
2814 (i) Exim was not creating retry information for temporary errors given
2815 for individual recipients after the DATA command when the smtp transport
2816 was used in LMTP mode. This meant that they could be retried too
2817 frequently, and not timed out correctly.
2818
2819 (ii) Exim was setting the flag that allows error details to be returned
2820 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2821 recipients that were returned after the DATA command.
2822
2823PH/53 This is related to PH/52, but is more general: for any failing address,
2824 when detailed error information was permitted to be returned to the
2825 sender, but the error was temporary, then after the final timeout, only
2826 "retry timeout exceeded" was returned. Now it returns the full error as
2827 well as "retry timeout exceeded".

2897PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2898 function verify_get_ident() calls ip_connect() to connect a socket, but
2899 if the "connect()" function timed out, ip_connect() used to close the
2900 socket. However, verify_get_ident() also closes the socket later, and in
2901 between Exim writes to the log, which may get opened at this point. When
2902 the socket was closed in ip_connect(), the log could get the same file
2903 descriptor number as the socket. This naturally causes chaos. The fix is
2904 not to close the socket in ip_connect(); the socket should be closed by
2905 the function that creates it. There was only one place in the code where
2906 this was missing, in the iplookup router, which I don't think anybody now
2907 uses, but I've fixed it anyway.

2930
2931 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2933
2934 (3) Reset the variables that are obtained from the first argument of
2935 ${prvscheck and used in the second argument before leaving the code,
2936 because their memory is reclaimed, so using them afterwards may do
2937 silly things.
2938
2939 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2940 one (it's much easier than Tom thought :-).

2964 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2965 not being looked up in the rDNS to get a host name, Exim was showing the
2966 IP address twice in Received: lines, even though the IP addresses were
2967 identical. For example:
2968
2969 Received: from [1.2.3.4] (helo=[1.2.3.4])
2970
2971 However, if the real host name was known, it was omitting the HELO data
2972 if it matched the actual IP address. This has been tidied up so that it
2973 doesn't show the same IP address twice.

3001
3002 Auto-submitted: auto-generated
3003
3004 in the messages that it generates (bounce messages and others, such as
3005 warnings). In the case of bounce messages for non-SMTP mesages, there was
3006 also a typo: it was using "Auto_submitted" (underscore instead of
3007 hyphen). Since every message generated by Exim is necessarily in response
3008 to another message, thes have all been changed to:

3010 Auto-Submitted: auto-replied
3011
3012 in accordance with these statements in the RFC:

3065 addresses acquired from the DNS when checking that the found name did
3066 have the original IP as one of its addresses. Since any found IPv6
3067 addresses are likely to be in abbreviated form, the comparison could
3068 fail. Luckily, there already exists a function for doing the comparison
3069 by converting both addresses to binary, so now that is used instead of
3070 the text comparison.

3149PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3150 run a filter in a subprocess. This could lead to confusion in subsequent
3151 lookups in the parent process. There should also be a search_tidyup() at
3152 the end of the subprocess.

3154PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3155 only if the host matched helo_try_verify_hosts, which caused the
3156 verification to occur when the EHLO/HELO command was issued. The ACL just
3157 tested the remembered result. Now, if a previous verification attempt has
3158 not happened, "verify = helo" does it there and then.

PH
3187PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3188 authentication with radiusclient 0.4.9:
3189
3190 - Error returned from rc_read_config was caught wrongly
3191 - Username/password not passed on to radius server due to wrong length.
3192
3193 The presumption is that some radiusclient API changes for 4.51/PH/17
3194 were not taken care of correctly. The code is still untested by me (my
3195 Linux distribution still has 0.3.2 of radiusclient), but it was
3196 contributed by a Radius user.

3211PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
3212 commands, but it was not correctly comparing the address with the actual

3214 header lines when this was not necessary.

3218PH/28 Exim tries to create and chdir to its spool directory when it starts;

3239PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
3240 Local/Makefile (with some defaults set). These are used in built scripts
3241 such as exicyclog, but they have never been used in the exim_install
3242 script (though there are many overriding facilities there). I have
3243 arranged that the exim_install script now takes note of these two
3244 settings.

3248PH/36 When a locally submitted message by a trusted user did not contain a
3249 From: header, and the sender address was obtained from -f or from an SMTP
3250 MAIL command, and the trusted user did not use -F to supply a sender
3251 name, $originator_name was incorrectly used when constructing a From:
3252 header. Furthermore, $originator_name was used for submission mode
3253 messages from external hosts without From: headers in a similar way,
3254 which is clearly wrong.
