JH
6JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
7 supports it and a size is available (ie. the sending peer gave us one).
8d042305 8
03d5892b
JH
9JH/02 The obsolete acl condition "demime" is removed (finally, after ten
10 years of being deprecated). The replacements are the ACLs
11 acl_smtp_mime and acl_not_smtp_mime.
12
4b0fe319
JH
13JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
14 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
15 or even an in-clear connection were permitted. Now, if the host lookup
16 was dnssec and dane was requested then the host is only used if the
17 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
18 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
19 if one fails this test.
20 This means that a poorly-configured remote DNS will make it incommunicado;
21 but it protects against a DNS-interception attack on it.

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

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

f42deca9 30 in rewrites and routers.

JH
32JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
33 and logged a warning sing 4.83; now they are a configuration file error.

35JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
36 (lacking @domain). Apply the same qualification processing as RCPT.

41Exim version 4.87
42-----------------
82d14d6a
JH
43JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
44 and 3.4.4 - once the server is enabled to respond to an OCSP request
45 it does even when not requested, resulting in a stapling non-aware
46 client dropping the TLS connection.
0d9b78be 47

TF
48TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
49 support variable-length bit vectors. No functional change.
50
ac881e27
TF
51TF/02 Improve the consistency of logging incoming and outgoing interfaces.
52 The I= interface field on outgoing lines is now after the H= remote
53 host field, same as incoming lines. There is a separate
54 outgoing_interface log selector which allows you to disable the
55 outgoing I= field.
56
c8899c20
JH
57JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
58 If not running log_selector +smtp_connection the mainlog would be held
59 open indefinitely after a "too many connections" event, including to a
60 deleted file after a log rotate. Leave the per net connection logging
61 leaving it open for efficiency as that will be quickly detected by the
62 check on the next write.
63

HSHR
64HS/01 Bug 1671: Fix post transport crash.
65 Processing the wait-<transport> messages could crash the delivery
66 process if the message IDs didn't exist for some reason. When
67 using 'split_spool_directory=yes' the construction of the spool
68 file name failed already, exposing the same netto behaviour.

70JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
71 mime_regex ACL conditions.

JH
73JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
74 to DSN fail messages (bounces): remote IP, remote greeting, remote response
75 to HELO, local diagnostic string.
76
805bb5c3
JH
77JH/05 Downgrade message for a TLS-certificate-based authentication fail from
78 log line to debug. Even when configured with a tls authenticator many
79 client connections are expected to not authenticate in this way, so
80 an authenticate fail is not an error.
81

HSHR
82HS/02 Add the Exim version string to the process info. This way exiwhat
83 gives some more detail about the running daemon.
84

JH
85JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
86 matter for fast-change records such as DNSBLs.
87
6f6dedcc
JH
88JH/07 Bug 1678: Always record an interface option value, if set, as part of a
89 retry record, even if constant. There may be multiple transports with
90 different interface settings and the retry behaviour needs to be kept
91 distinct.
92

JH
93JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.

98
41e93589
JH
99JH/11 Bug 830: use same host for all RCPTS of a message, even under
100 hosts_randomize. This matters a lot when combined with mua_wrapper.
101
98b98887 102JH/12 Bug 1706: percent and underbar characters are no longer escaped by the

107JH/14 Change header file name for freeradius-client. Relevant if compiling
108 with Radius support; from the Gentoo tree and checked under Fedora.

JB
115JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
116
23f3dc67
JH
117JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
118 defaults to "*" (all hosts). The variable is now available when not built
119 with TLS, default unset, mainly to enable keeping the testuite sane.
120 If a server certificate is not supplied (via tls_certificate) an error is
121 logged, and clients will find TLS connections fail on startup. Presumably
122 they will retry in-clear.
123 Packagers of Exim are strongly encouraged to create a server certificate
124 at installation time.
125
240c288f
JH
126HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
127 with the $config_file variable.
128
5ef5dd52
JB
129JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
130 in transport context, after the attempt, and per-recipient. The latter type
131 is per host attempted. The event data is the error message, and the errno
132 information encodes the lookup type (A vs. MX) used for the (first) host,
133 and the trailing two digits of the smtp 4xx reponse.
134
e161710d
GF
135GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
136 to write to mainlog (or rejectlog, paniclog) in the window between file
137 creation and permissions/ownership being changed. Particularly affects
138 installations where exicyclog is run as root, rather than exim user;
139 result is that the running daemon panics and dies.
140
a159f203
JH
141JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
142
7f06582c
JH
143JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
144 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
145 "pri" and "weight". Note that the previous implicit priority given by the
146 list order is no longer honoured.
147
abe1010c

148JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
149 for DKIM processing.

cee5f132
JH
154JH/26 Move PROXY support from Experimental to mainline, enabled for a build
155 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
156 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
157 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 158

173JH/32 Move Redis support from Experimental to mainline, enabled for a build
174 by defining LOOKUP_REDIS. The libhiredis library is required.
175
379ba7d0
JH
176JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
177 keys are given for lookup.
178
f444c2c7
JH
179JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
180 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
181 only supported when built with TLS support. The PolarSSL SHA routines
182 are still used when the TLS library is too old for convenient support.
f444c2c7 183
a57b6200
JH
184JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
185 openssl_options), for security. OpenSSL forces this from version 1.1.0
186 server-side so match that on older versions.
187
07c73177 188JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 189 allocation for $value could be released as the expansion processing
07c73177 190 concluded, but leaving the global pointer active for it.
fa01e4f8 191
4f6ae5c3
JH
192JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
193 and to use the domains and local_parts ACL conditions.
194
1bc460a6
JH
195JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
196 incorrectly not doubled on cutthrough transmission, hence seen as a
197 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 198 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
199 via the normal store-and-forward channel. This could result in duplicates
200 received - but deduplicating mailstores were liable to retain only the
201 initial truncated version.

214JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
215 either intentional arithmetic overflow during PRNG, or testing config-

JH
225JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
226 Many were false-positives and ignorable, but it's worth fixing the

JH
229JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
230 for the new environment-manipulation done at startup. Move the routines
231 from being local to tls.c to being global via the os.c file.
232
93cc2d6e
JH
233JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
234 an extract embedded as result-arg for a map, the first arg for extract
235 is unavailable so we cannot tell if this is a numbered or keyed
236 extraction. Accept either.

248 it.
249
01a4a5c5 250JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 251 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
252 can be used to disable this per-host. The build option
253 EXPERIMENTAL_CERTNAMES is withdrawn.

JH
257 For GnuTLS, only version 3.0.20 or later.
258
610ff438 259JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
260 (but not required) by default. The verification status is now logged by
261 default, for both outbound TLS and client-certificate supplying inbound
262 TLS connections
610ff438 263

265 sites use this now.
266
50dc7409
JH
267JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
268 Status Notification (bounce) messages are now MIME format per RFC 3464.
269 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
270 under the control of the dsn_advertise_hosts option, and routers may
271 have a dsn_lasthop option.
272

273JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
274 default, modifiable by a malware= option. The list separator for

362Exim version 4.85
363-----------------
364TL/01 When running the test suite, the README says that variables such as
365 no_msglog_check are global and can be placed anywhere in a specific
366 test's script, however it was observed that placement needed to be near
367 the beginning for it to behave that way. Changed the runtest perl
368 script to read through the entire script once to detect and set these
369 variables, reset to the beginning of the script, and then run through
370 the script parsing/test process like normal.

397JH/05 Fix results-pipe from transport process. Several recipients, combined
398 with certificate use, exposed issues where response data items split
399 over buffer boundaries were not parsed properly. This eventually
400 resulted in duplicates being sent. This issue only became common enough
401 to notice due to the introduction of conection certificate information,
402 the item size being so much larger. Found and fixed by Wolfgang Breyha.

727TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
728
729 When a queue runner is handling a message, Exim first routes the
730 recipient addresses, during which it prunes them based on the retry
731 hints database. After that it attempts to deliver the message to
732 any remaining recipients. It then updates the hints database using
733 the retry rules.
734
735 So if a recipient address works intermittently, it can get repeatedly
736 deferred at routing time. The retry hints record remains fresh so the
737 address never reaches the final cutoff time.
738
739 This is a fairly common occurrence when a user is bumping up against
740 their storage quota. Exim had some logic in its local delivery code
741 to deal with this. However it did not apply to per-recipient defers
742 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
743
1ddeb334
TF
744 This change adds a proper retry rule check during routing so that the
745 final cutoff time is checked against the message's age. We only do
746 this check if there is an address retry record and there is not a
747 domain retry record; this implies that previous attempts to handle
748 the address had the retry_use_local_parts option turned on. We use
749 this as an approximation for the destination being like a local
750 delivery, as in LMTP.
67bd1ab3
TF
751
752 I suspect this new check makes the old local delivery cutoff check
753 redundant, but I have not verified this so I left the code in place.

1075TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1076 lock up or crash if it happened to be inside a call to libc when it
1077 got a SIGUSR1 from exiwhat.
1078
1079 The SIGUSR1 handler appends the current process status to the process
1080 log which is later printed by exiwhat. It used to use the general
1081 purpose logging code to do this, but several functions it calls are
1082 not safe for signals.
1083
1084 The new output code in the SIGUSR1 handler is specific to the process
1085 log, and simple enough that it's easy to inspect for signal safety.
1086 Removing some special cases also simplifies the general logging code.
1087 Removing the spurious timestamps from the process log simplifies
1088 exiwhat.
1089
c99ce5c9
TF
1090TF/04 Improved ratelimit ACL condition.
1091
1092 The /noupdate option has been deprecated in favour of /readonly which
1093 has clearer semantics. The /leaky, /strict, and /readonly update modes
1094 are mutually exclusive. The update mode is no longer included in the
1095 database key; it just determines when the database is updated. (This
1096 means that when you upgrde Exim will forget old rate measurements.)
1097
1098 Exim now checks that the per_* options are used with an update mode that
1099 makes sense for the current ACL. For example, when Exim is processing a
1100 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1101 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1102 must specify per_mail/readonly. If you omit the update mode it defaults to
1103 /leaky where that makes sense (as before) or /readonly where required.
1104
1105 The /noupdate option is now undocumented but still supported for
1106 backwards compatibility. It is equivalent to /readonly except that in
1107 ACLs where /readonly is required you may specify /leaky/noupdate or
1108 /strict/noupdate which are treated the same as /readonly.
1109
1110 A useful new feature is the /count= option. This is a generalization
1111 of the per_byte option, so that you can measure the throughput of other
1112 aggregate values. For example, the per_byte option is now equivalent
1113 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1114
1115 The per_rcpt option has been generalized using the /count= mechanism
1116 (though it's more complicated than the per_byte equivalence). When it is
1117 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1118 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1119 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1120 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1121 Note that using per_rcpt with a non-readonly update mode in more than
1122 one ACL will cause the recipients to be double-counted. (The per_mail
1123 and per_byte options don't have this problem.)
1124
1125 The handling of very low rates has changed slightly. If the computed rate
1126 is less than the event's count (usually one) then this event is the first
1127 after a long gap. In this case the rate is set to the same as this event's
1128 count, so that the first message of a spam run is counted properly.
1129
1130 The major new feature is a mechanism for counting the rate of unique
1131 events. The new per_addr option counts the number of different
1132 recipients that someone has sent messages to in the last time period. It
1133 behaves like per_rcpt if all the recipient addresses are different, but
1134 duplicate recipient addresses do not increase the measured rate. Like
1135 the /count= option this is a general mechanism, so the per_addr option
1136 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1137 example, measure the rate that a client uses different sender addresses
1138 with the options per_mail/unique=$sender_address. There are further
1139 details in the main documentation.

1690 were called 'true' and it seems that C99 defines that as a reserved

1710
1711PH/01 Another patch from the Sieve maintainer.
1712
6a3bceb1
PH
1713PH/02 When an IPv6 address is converted to a string for single-key lookup
1714 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1715 dots are used instead of colons so that keys in lsearch files need not
1716 contain colons. This was done some time before quoting was made available
1717 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1718 (notated using the quote facility) so as to distinguish them from IPv4
1719 keys. This meant that lookups for IP addresses in host lists did not work
1720 for iplsearch lookups.
1721
1722 This has been fixed by arranging for IPv6 addresses to be expressed with
1723 colons if the lookup type is iplsearch. This is not incompatible, because
1724 previously such lookups could never work.
1725
1726 The situation is now rather anomolous, since one *can* have colons in
1727 ordinary lsearch keys. However, making the change in all cases is
1728 incompatible and would probably break a number of configurations.

MH
1733MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1734 conversion specification without a maximum field width, thereby enabling
1735 a rogue spamd server to cause a buffer overflow. While nobody in their
1736 right mind would setup Exim to query an untrusted spamd server, an
1737 attacker that gains access to a server running spamd could potentially
1738 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1743MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1744 a directory entry by the name of the lookup key. Previously, if a
1745 symlink pointed to a non-existing file or a file in a directory that
1746 Exim lacked permissions to read, a lookup for a key matching that
1747 symlink would fail. Now it is enough that a matching directory entry
1748 exists, symlink or not. (Bugzilla 503.)

1825 if a client was not listed at all, or was listed with a value other than

1931PH/29 SMTP synchronization checks are implemented when a command is read -
1932 there is a check that no more input is waiting when there shouldn't be

1934 some time before the response is written. In this time, more input might
1935 arrive, invalidly. So now there are extra checks after an ACL has run for
1936 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1937 pipelining has not been advertised.

1952 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1953 was a macro that became an assignment, so it seemed to work. This has
1954 changed to a proper function call with a void return, hence the compile

2014 any further data because there won't be any more messages to send. A call
2015 to select() can be used: if it shows that the input is "ready", there is
2016 either input waiting, or the socket has been closed. An attempt to read

2029PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2030 fixed by 4.65/MH/01 (is this a record?) are fixed:
2031
2032 (i) An empty string was always treated as zero by the numeric comparison
2033 operators. This behaviour has been restored.
2034
2035 (ii) It is documented that the numeric comparison operators always treat
2036 their arguments as decimal numbers. This was broken in that numbers
2037 starting with 0 were being interpreted as octal.
2038
2039 While fixing these problems I realized that there was another issue that
2040 hadn't been noticed. Values of message_size_limit (both the global option
2041 and the transport option) were treated as octal if they started with 0.
2042 The documentation was vague. These values are now always treated as
2043 decimal, and I will make that clear in the documentation.

2060 large number of recipients for a single message is ridiculous

PH
2087PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2088 callout verification, Exim cached a "reject" for the entire domain. This
2089 is correct for most verifications, but it is not correct for a recipient
2090 verification with use_sender or use_postmaster set, because in that case
2091 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2092 case of MAIL FROM:<> rejection from other early rejections (e.g.
2093 rejection of HELO). When verifying a recipient using a non-null MAIL
2094 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2095 Whatever the result of the callout, the value of the domain cache is
2096 left unchanged (for any other kind of callout, getting as far as trying
2097 RCPT means that the domain itself is ok).

2133 probably the interface on which it is arriving) and not to the outgoing
2134 callout (which could be using a different interface). This has been
2135 changed to use the value of the helo_data option from the smtp transport
2136 instead - this is what is used when a message is actually being sent. If
2137 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
2142 (a) The code assumed that strncpy() returns a negative number on buffer
2143 overflow, which isn't the case. Replaced with Exim's string_format()
2144 function.
2145 (b) There were several signed/unsigned issues. I just did the minimum
2146 hacking in of casts. There is scope for a larger refactoring.
2147 (c) The code used strcasecmp() which is not a standard C function.
2148 Replaced with Exim's strcmpic() function.
2149 (d) The code set only $1; it now sets $auth1 as well.
2150 (e) A simple test gave the error "authentication client didn't specify
2151 service in request". It would seem that Dovecot has changed its
2152 interface. Fortunately there's a specification; I followed it and
2153 changed what the client sends and it appears to be working now.

2159 address A is aliased to B and C, where B exists and C does not. Without
2160 -v the output is "A verified" because verification stops after a
2161 successful redirection if more than one address is generated. However,
2162 with -v the child addresses are also verified. Exim was outputting "A
2163 failed to verify" and then showing the successful verification for C,
2164 with its parentage. It now outputs "B failed to verify", showing B's
2165 parentage before showing the successful verification of C.

PH
2171PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2172 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2173 they consult the DNS. I had assumed they would set it the way they
2174 wanted; and indeed my experiments on Linux seem to show that in some
2175 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2176 To be on the safe side, however, I have now made the interface to
2177 host_find_byname() similar to host_find_bydns(), with an argument
2178 containing the DNS resolver options. The host_find_byname() function now
2179 sets these options at its start, just as host_find_bydns() does. The smtp
2180 transport options dns_qualify_single and dns_search_parents are passed to
2181 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2182 of host_find_byname() use the default settings of RES_DEFNAMES
2183 (qualify_single) but not RES_DNSRCH (search_parents).

2185PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2186 spool_read_header() do less string testing, by means of a preliminary
2187 switch on the second character of optional "-foo" lines. (This is
2188 overdue, caused by the large number of possibilities that now exist.
2189 Originally there were few.) While I was there, I also converted the
2190 str(n)cmp tests so they don't re-test the leading "-" and the first
2191 character, in the hope this might squeeze out yet more improvement.

2193PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2194 flag allowing group syntax was set by the header_syntax check but not
2195 turned off, possible causing trouble later; (2) The flag was not being
2196 set at all for the header_verify test, causing "group"-style headers to
2197 be rejected. I have now set it in this case, and also caused header_
2198 verify to ignore an empty address taken from a group. While doing this, I
2199 came across some other cases where the code for allowing group syntax
2200 while scanning a header line wasn't quite right (mostly, not resetting
2201 the flag correctly in the right place). These bugs could have caused
2202 trouble for malformed header lines. I hope it is now all correct.

PH
2204PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2205 with the "reply" argument non-NULL. The code, however (which originally
2206 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2207 but it didn't always do it. This confused somebody who was copying the
2208 code for some other use. I have removed all the tests.

PH
2210PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2211 feature that was used to support insecure browsers during the U.S. crypto
2212 embargo. It requires special client support, and Exim is probably the
2213 only MTA that supported it -- and would never use it because real RSA is
2214 always available. This code has been removed, because it had the bad
2215 effect of slowing Exim down by computing (never used) parameters for the
2216 RSA_EXPORT functionality.

2221 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2222 if the connection is using TLS or if the remote IP is the same as the
2223 local IP, and the "valid-client-cert option" if a client certificate has

PH
2255
2256PH/30 Exim was sometimes attempting to deliver messages that had suffered
2257 address errors (4xx response to RCPT) over the same connection as other
2258 messages routed to the same hosts. Such deliveries are always "forced",
2259 so retry times are not inspected. This resulted in far too many retries
2260 for the affected addresses. The effect occurred only when there were more
2261 hosts than the hosts_max_try setting in the smtp transport when it had
2262 the 4xx errors. Those hosts that it had tried were not added to the list
2263 of hosts for which the message was waiting, so if all were tried, there
2264 was no problem. Two fixes have been applied:
2265
2266 (i) If there are any address or message errors in an SMTP delivery, none
2267 of the hosts (tried or untried) are now added to the list of hosts
2268 for which the message is waiting, so the message should not be a
2269 candidate for sending over the same connection that was used for a
2270 successful delivery of some other message. This seems entirely
2271 reasonable: after all the message is NOT "waiting for some host".
2272 This is so "obvious" that I'm not sure why it wasn't done
2273 previously. Hope I haven't missed anything, but it can't do any
2274 harm, as the worst effect is to miss an optimization.
2275
2276 (ii) If, despite (i), such a delivery is accidentally attempted, the
2277 routing retry time is respected, so at least it doesn't keep
2278 hammering the server.

2293PH/35 The error "getsockname() failed: connection reset by peer" was being
2294 written to the panic log as well as the main log, but it isn't really

2296 removed the panic log writing for the ECONNRESET error when getsockname()
2297 fails.
2298
48c7f9e2
PH
2299PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2300 runs only) independently of the message's sender address. This meant
2301 that, if the 4xx error was in fact related to the sender, a different
2302 message to the same recipient with a different sender could confuse
2303 things. In particualar, this can happen when sending to a greylisting
2304 server, but other circumstances could also provoke similar problems.
2305 I have changed the default so that the retry time for these errors is now
2306 based a combination of the sender and recipient addresses. This change
2307 can be overridden by setting address_retry_include_sender=false in the
2308 smtp transport.

2576PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2579 tcp-wrappers gives "deny", whereas what one would like would be some
2580 kind of temporary error. A kludge has been added to help with this.
2581 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2582 554 error is used if errno is still zero or contains ENOENT (which occurs
2583 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2669 autoreply, Exim could try to deliver to a non-existent relative file

2706 major problems that occur when a DNS server includes only records of one
2707 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2708 fixed another bug: if SRV records were looked up and the corresponding
2709 address records were *not* found in the additional section, the port
2710 values from the SRV records were lost.

2720PH/19 When calculating a retry time, Exim used to measure the "time since
2721 failure" by looking at the "first failed" field in the retry record. Now
2722 it does not use this if it is later than than the arrival time of the
2723 message. Instead it uses the arrival time. This makes for better
2724 behaviour in cases where some deliveries succeed, thus re-setting the
2725 "first failed" field. An example is a quota failure for a huge message
2726 when small messages continue to be delivered. Without this change, the
2727 "time since failure" will always be short, possible causing more frequent
2728 delivery attempts for the huge message than are intended.

2825PH/42 The content-scanning code uses fopen() to create files in which to put
2826 message data. Previously it was not paying any attention to the mode of
2827 the files. Exim runs with umask(0) because the rest of the code creates
2828 files with open(), and sets the required mode explicitly. Thus, these
2829 files were ending up world-writeable. This was not a big issue, because,
2830 being within the spool directory, they were not world-accessible. I have
2831 created a function called modefopen, which takes an additional mode
2832 argument. It sets umask(777), creates the file, chmods it to the required
2833 mode, then resets the umask. All the relevant calls to fopen() in the
2834 content scanning code have been changed to use this function.

2871
2872 (i) Exim was not creating retry information for temporary errors given
2873 for individual recipients after the DATA command when the smtp transport
2874 was used in LMTP mode. This meant that they could be retried too
2875 frequently, and not timed out correctly.
2876
2877 (ii) Exim was setting the flag that allows error details to be returned
2878 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2879 recipients that were returned after the DATA command.
2880
2881PH/53 This is related to PH/52, but is more general: for any failing address,
2882 when detailed error information was permitted to be returned to the
2883 sender, but the error was temporary, then after the final timeout, only
2884 "retry timeout exceeded" was returned. Now it returns the full error as

2955PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2956 function verify_get_ident() calls ip_connect() to connect a socket, but
2957 if the "connect()" function timed out, ip_connect() used to close the
2958 socket. However, verify_get_ident() also closes the socket later, and in
2959 between Exim writes to the log, which may get opened at this point. When
2960 the socket was closed in ip_connect(), the log could get the same file
2961 descriptor number as the socket. This naturally causes chaos. The fix is
2962 not to close the socket in ip_connect(); the socket should be closed by
2963 the function that creates it. There was only one place in the code where
2964 this was missing, in the iplookup router, which I don't think anybody now
2965 uses, but I've fixed it anyway.

3026
3027 Received: from [1.2.3.4] (helo=[1.2.3.4])

3123 addresses acquired from the DNS when checking that the found name did
3124 have the original IP as one of its addresses. Since any found IPv6
3125 addresses are likely to be in abbreviated form, the comparison could
3126 fail. Luckily, there already exists a function for doing the comparison
3127 by converting both addresses to binary, so now that is used instead of
3128 the text comparison.

PH
3130PH/20 There was another similar case to PH/19, when a complete host name was
3131 given in a host list; looking up its IP address could give an abbreviated
3132 form, whereas the current host's name might or might not be abbreviated.
3133 The same fix has been applied.

3148PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
3149 header line, restrict the check to what is listed in RFCs 2369 and 2929.
3150 Also, for "Auto-Submitted", treat anything other than "no" as
3151 non-personal, in accordance with RFC 3834. (Previously it treated
3152 anything starting "auto-" as non-personal.)

3154TF/01 The control=submission/name=... option had a problem with syntax
3155 errors if the name included a slash character. The /name= option
3156 now slurps the rest of the string, so it can include any characters
3157 but it must come last in the list of options (after /sender_retain
3158 or /domain=).

PH
3175PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
3176 fread() to skip over the body file's header line, because in Cygwin the
3177 header line is locked and is inaccessible.

PH
3179PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
3180 co-exist for some time) to make it clear that it is the Exim ID that is
3181 referenced, not the Message-ID: header line.

3207PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3208 run a filter in a subprocess. This could lead to confusion in subsequent
3209 lookups in the parent process. There should also be a search_tidyup() at
3210 the end of the subprocess.

PH
3212PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3213 only if the host matched helo_try_verify_hosts, which caused the
3214 verification to occur when the EHLO/HELO command was issued. The ACL just
3215 tested the remembered result. Now, if a previous verification attempt has
3216 not happened, "verify = helo" does it there and then.

3245PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3246 authentication with radiusclient 0.4.9:
3247
3248 - Error returned from rc_read_config was caught wrongly
3249 - Username/password not passed on to radius server due to wrong length.
3250
3251 The presumption is that some radiusclient API changes for 4.51/PH/17
3252 were not taken care of correctly. The code is still untested by me (my
3253 Linux distribution still has 0.3.2 of radiusclient), but it was
3254 contributed by a Radius user.

3269PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3311 messages from external hosts without From: headers in a similar way,
3312 which is clearly wrong.
