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.

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.

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

51TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
52 support variable-length bit vectors. No functional change.
53
ac881e27
TF
54TF/02 Improve the consistency of logging incoming and outgoing interfaces.
55 The I= interface field on outgoing lines is now after the H= remote
56 host field, same as incoming lines. There is a separate
57 outgoing_interface log selector which allows you to disable the
58 outgoing I= field.
59
c8899c20
JH
60JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
61 If not running log_selector +smtp_connection the mainlog would be held
62 open indefinitely after a "too many connections" event, including to a
63 deleted file after a log rotate. Leave the per net connection logging
64 leaving it open for efficiency as that will be quickly detected by the
65 check on the next write.
66

HSHR
67HS/01 Bug 1671: Fix post transport crash.
68 Processing the wait-<transport> messages could crash the delivery
69 process if the message IDs didn't exist for some reason. When
70 using 'split_spool_directory=yes' the construction of the spool
71 file name failed already, exposing the same netto behaviour.
72

73JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
74 mime_regex ACL conditions.

JH
76JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
77 to DSN fail messages (bounces): remote IP, remote greeting, remote response
78 to HELO, local diagnostic string.
79
805bb5c3
JH
80JH/05 Downgrade message for a TLS-certificate-based authentication fail from
81 log line to debug. Even when configured with a tls authenticator many
82 client connections are expected to not authenticate in this way, so
83 an authenticate fail is not an error.
84

HSHR
85HS/02 Add the Exim version string to the process info. This way exiwhat
86 gives some more detail about the running daemon.
87

JH
88JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
89 matter for fast-change records such as DNSBLs.
90
6f6dedcc
JH
91JH/07 Bug 1678: Always record an interface option value, if set, as part of a
92 retry record, even if constant. There may be multiple transports with
93 different interface settings and the retry behaviour needs to be kept
94 distinct.
95
0f557e90
JH
96JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.

JH
102JH/11 Bug 830: use same host for all RCPTS of a message, even under
103 hosts_randomize. This matters a lot when combined with mua_wrapper.
104
98b98887 105JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0
JH
106 ${quote_pgsql:<string>} operator.

110JH/14 Change header file name for freeradius-client. Relevant if compiling
111 with Radius support; from the Gentoo tree and checked under Fedora.

118JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
119
23f3dc67
JH
120JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
121 defaults to "*" (all hosts). The variable is now available when not built
122 with TLS, default unset, mainly to enable keeping the testuite sane.
123 If a server certificate is not supplied (via tls_certificate) an error is
124 logged, and clients will find TLS connections fail on startup. Presumably
125 they will retry in-clear.
126 Packagers of Exim are strongly encouraged to create a server certificate
127 at installation time.
128
240c288f
JH
129HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
130 with the $config_file variable.
131
5ef5dd52
JB
132JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
133 in transport context, after the attempt, and per-recipient. The latter type
134 is per host attempted. The event data is the error message, and the errno
135 information encodes the lookup type (A vs. MX) used for the (first) host,
136 and the trailing two digits of the smtp 4xx reponse.
137
e161710d
GF
138GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
139 to write to mainlog (or rejectlog, paniclog) in the window between file
140 creation and permissions/ownership being changed. Particularly affects
141 installations where exicyclog is run as root, rather than exim user;
142 result is that the running daemon panics and dies.
143

JH
144JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
145
7f06582c
JH
146JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
147 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
148 "pri" and "weight". Note that the previous implicit priority given by the
149 list order is no longer honoured.

152 for DKIM processing.

155 by defining SUPPORT_SOCKS.
74f150bf 156
cee5f132
JH
157JH/26 Move PROXY support from Experimental to mainline, enabled for a build
158 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
159 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
160 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 161

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

217JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
218 either intentional arithmetic overflow during PRNG, or testing config-

222 delivery resulted in actual delivery. Cancel cutthrough before DATA

226 rejects a recipient: pass the reject to the originator.

dc8091e7
JH
228JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
229 Many were false-positives and ignorable, but it's worth fixing the
230 former class.

dfe7d917
JH
232JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
233 for the new environment-manipulation done at startup. Move the routines
234 from being local to tls.c to being global via the os.c file.
235
93cc2d6e
JH
236JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
237 an extract embedded as result-arg for a map, the first arg for extract
238 is unavailable so we cannot tell if this is a numbered or keyed
239 extraction. Accept either.

251 it.
252
01a4a5c5 253JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 254 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
255 can be used to disable this per-host. The build option
256 EXPERIMENTAL_CERTNAMES is withdrawn.

JH
260 For GnuTLS, only version 3.0.20 or later.
261
610ff438 262JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
263 (but not required) by default. The verification status is now logged by
264 default, for both outbound TLS and client-certificate supplying inbound
265 TLS connections
610ff438 266
f926e272

267JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
268 sites use this now.

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

276JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
277 default, modifiable by a malware= option. The list separator for

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

375TL/02 The BSD's have an arc4random API. One of the functions to induce
376 adding randomness was arc4random_stir(), but it has been removed in

383TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
384 syntax errors in an expansion can be treated as a string instead of

401 with certificate use, exposed issues where response data items split
402 over buffer boundaries were not parsed properly. This eventually
403 resulted in duplicates being sent. This issue only became common enough
404 to notice due to the introduction of conection certificate information,
405 the item size being so much larger. Found and fixed by Wolfgang Breyha.

730TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
731
732 When a queue runner is handling a message, Exim first routes the
733 recipient addresses, during which it prunes them based on the retry
734 hints database. After that it attempts to deliver the message to
735 any remaining recipients. It then updates the hints database using
736 the retry rules.
737
738 So if a recipient address works intermittently, it can get repeatedly
739 deferred at routing time. The retry hints record remains fresh so the
740 address never reaches the final cutoff time.
741
742 This is a fairly common occurrence when a user is bumping up against
743 their storage quota. Exim had some logic in its local delivery code
744 to deal with this. However it did not apply to per-recipient defers
745 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
746
1ddeb334
TF
747 This change adds a proper retry rule check during routing so that the
748 final cutoff time is checked against the message's age. We only do
749 this check if there is an address retry record and there is not a
750 domain retry record; this implies that previous attempts to handle
751 the address had the retry_use_local_parts option turned on. We use
752 this as an approximation for the destination being like a local
753 delivery, as in LMTP.
67bd1ab3
TF
754
755 I suspect this new check makes the old local delivery cutoff check
756 redundant, but I have not verified this so I left the code in place.

794 advertises the facility. If the client requests PRDR a new
795 acl_data_smtp_prdr ACL is called once for each recipient, after
796 the body content is received and before the acl_smtp_data ACL.
797 The client is controlled by bolth of: a hosts_try_prdr option
798 on the smtp transport, and the server advertisement.
799 Default client logging of deliveries and rejections involving
800 PRDR are flagged with the string "PRDR".

1078TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1079 lock up or crash if it happened to be inside a call to libc when it
1080 got a SIGUSR1 from exiwhat.
1081
1082 The SIGUSR1 handler appends the current process status to the process
1083 log which is later printed by exiwhat. It used to use the general
1084 purpose logging code to do this, but several functions it calls are
1085 not safe for signals.
1086
1087 The new output code in the SIGUSR1 handler is specific to the process
1088 log, and simple enough that it's easy to inspect for signal safety.
1089 Removing some special cases also simplifies the general logging code.
1090 Removing the spurious timestamps from the process log simplifies
1091 exiwhat.

TF
1093TF/04 Improved ratelimit ACL condition.
1094
1095 The /noupdate option has been deprecated in favour of /readonly which
1096 has clearer semantics. The /leaky, /strict, and /readonly update modes
1097 are mutually exclusive. The update mode is no longer included in the
1098 database key; it just determines when the database is updated. (This
1099 means that when you upgrde Exim will forget old rate measurements.)
1100
1101 Exim now checks that the per_* options are used with an update mode that
1102 makes sense for the current ACL. For example, when Exim is processing a
1103 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1104 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1105 must specify per_mail/readonly. If you omit the update mode it defaults to
1106 /leaky where that makes sense (as before) or /readonly where required.
1107
1108 The /noupdate option is now undocumented but still supported for
1109 backwards compatibility. It is equivalent to /readonly except that in
1110 ACLs where /readonly is required you may specify /leaky/noupdate or
1111 /strict/noupdate which are treated the same as /readonly.
1112
1113 A useful new feature is the /count= option. This is a generalization
1114 of the per_byte option, so that you can measure the throughput of other
1115 aggregate values. For example, the per_byte option is now equivalent
1116 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1117
1118 The per_rcpt option has been generalized using the /count= mechanism
1119 (though it's more complicated than the per_byte equivalence). When it is
1120 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1121 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1122 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1123 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1124 Note that using per_rcpt with a non-readonly update mode in more than
1125 one ACL will cause the recipients to be double-counted. (The per_mail
1126 and per_byte options don't have this problem.)
1127
1128 The handling of very low rates has changed slightly. If the computed rate
1129 is less than the event's count (usually one) then this event is the first
1130 after a long gap. In this case the rate is set to the same as this event's
1131 count, so that the first message of a spam run is counted properly.
1132
1133 The major new feature is a mechanism for counting the rate of unique
1134 events. The new per_addr option counts the number of different
1135 recipients that someone has sent messages to in the last time period. It
1136 behaves like per_rcpt if all the recipient addresses are different, but
1137 duplicate recipient addresses do not increase the measured rate. Like
1138 the /count= option this is a general mechanism, so the per_addr option
1139 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1140 example, measure the rate that a client uses different sender addresses
1141 with the options per_mail/unique=$sender_address. There are further
1142 details in the main documentation.

1693 were called 'true' and it seems that C99 defines that as a reserved

1712-----------------
1713
1714PH/01 Another patch from the Sieve maintainer.
1715
6a3bceb1
PH
1716PH/02 When an IPv6 address is converted to a string for single-key lookup
1717 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1718 dots are used instead of colons so that keys in lsearch files need not
1719 contain colons. This was done some time before quoting was made available
1720 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1721 (notated using the quote facility) so as to distinguish them from IPv4
1722 keys. This meant that lookups for IP addresses in host lists did not work
1723 for iplsearch lookups.
1724
1725 This has been fixed by arranging for IPv6 addresses to be expressed with
1726 colons if the lookup type is iplsearch. This is not incompatible, because
1727 previously such lookups could never work.
1728
1729 The situation is now rather anomolous, since one *can* have colons in
1730 ordinary lsearch keys. However, making the change in all cases is
1731 incompatible and would probably break a number of configurations.
1732

MH
1736MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1737 conversion specification without a maximum field width, thereby enabling
1738 a rogue spamd server to cause a buffer overflow. While nobody in their
1739 right mind would setup Exim to query an untrusted spamd server, an
1740 attacker that gains access to a server running spamd could potentially
1741 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1746MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1747 a directory entry by the name of the lookup key. Previously, if a
1748 symlink pointed to a non-existing file or a file in a directory that
1749 Exim lacked permissions to read, a lookup for a key matching that
1750 symlink would fail. Now it is enough that a matching directory entry
1751 exists, symlink or not. (Bugzilla 503.)

1828 if a client was not listed at all, or was listed with a value other than
1829 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1830 the condition was not true (as it should be), so access was not denied.

1934PH/29 SMTP synchronization checks are implemented when a command is read -
1935 there is a check that no more input is waiting when there shouldn't be

1937 some time before the response is written. In this time, more input might
1938 arrive, invalidly. So now there are extra checks after an ACL has run for
1939 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1940 pipelining has not been advertised.

1955 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1956 was a macro that became an assignment, so it seemed to work. This has

2017 any further data because there won't be any more messages to send. A call
2018 to select() can be used: if it shows that the input is "ready", there is
2019 either input waiting, or the socket has been closed. An attempt to read

2032PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2033 fixed by 4.65/MH/01 (is this a record?) are fixed:
2034
2035 (i) An empty string was always treated as zero by the numeric comparison
2036 operators. This behaviour has been restored.
2037
2038 (ii) It is documented that the numeric comparison operators always treat
2039 their arguments as decimal numbers. This was broken in that numbers
2040 starting with 0 were being interpreted as octal.
2041
2042 While fixing these problems I realized that there was another issue that
2043 hadn't been noticed. Values of message_size_limit (both the global option
2044 and the transport option) were treated as octal if they started with 0.
2045 The documentation was vague. These values are now always treated as
2046 decimal, and I will make that clear in the documentation.

PH
2090PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2091 callout verification, Exim cached a "reject" for the entire domain. This
2092 is correct for most verifications, but it is not correct for a recipient
2093 verification with use_sender or use_postmaster set, because in that case
2094 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2095 case of MAIL FROM:<> rejection from other early rejections (e.g.
2096 rejection of HELO). When verifying a recipient using a non-null MAIL
2097 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2098 Whatever the result of the callout, the value of the domain cache is
2099 left unchanged (for any other kind of callout, getting as far as trying
2100 RCPT means that the domain itself is ok).

2136 probably the interface on which it is arriving) and not to the outgoing
2137 callout (which could be using a different interface). This has been
2138 changed to use the value of the helo_data option from the smtp transport
2139 instead - this is what is used when a message is actually being sent. If
2140 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
2145 (a) The code assumed that strncpy() returns a negative number on buffer
2146 overflow, which isn't the case. Replaced with Exim's string_format()
2147 function.
2148 (b) There were several signed/unsigned issues. I just did the minimum
2149 hacking in of casts. There is scope for a larger refactoring.
2150 (c) The code used strcasecmp() which is not a standard C function.
2151 Replaced with Exim's strcmpic() function.
2152 (d) The code set only $1; it now sets $auth1 as well.
2153 (e) A simple test gave the error "authentication client didn't specify
2154 service in request". It would seem that Dovecot has changed its
2155 interface. Fortunately there's a specification; I followed it and
2156 changed what the client sends and it appears to be working now.

2162 address A is aliased to B and C, where B exists and C does not. Without
2163 -v the output is "A verified" because verification stops after a
2164 successful redirection if more than one address is generated. However,
2165 with -v the child addresses are also verified. Exim was outputting "A
2166 failed to verify" and then showing the successful verification for C,
2167 with its parentage. It now outputs "B failed to verify", showing B's
2168 parentage before showing the successful verification of C.

322050c2
PH
2174PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2175 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2176 they consult the DNS. I had assumed they would set it the way they
2177 wanted; and indeed my experiments on Linux seem to show that in some
2178 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2179 To be on the safe side, however, I have now made the interface to
2180 host_find_byname() similar to host_find_bydns(), with an argument
2181 containing the DNS resolver options. The host_find_byname() function now
2182 sets these options at its start, just as host_find_bydns() does. The smtp
2183 transport options dns_qualify_single and dns_search_parents are passed to
2184 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2185 of host_find_byname() use the default settings of RES_DEFNAMES
2186 (qualify_single) but not RES_DNSRCH (search_parents).

2188PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2189 spool_read_header() do less string testing, by means of a preliminary
2190 switch on the second character of optional "-foo" lines. (This is
2191 overdue, caused by the large number of possibilities that now exist.
2192 Originally there were few.) While I was there, I also converted the
2193 str(n)cmp tests so they don't re-test the leading "-" and the first
2194 character, in the hope this might squeeze out yet more improvement.

2196PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2197 flag allowing group syntax was set by the header_syntax check but not
2198 turned off, possible causing trouble later; (2) The flag was not being
2199 set at all for the header_verify test, causing "group"-style headers to
2200 be rejected. I have now set it in this case, and also caused header_
2201 verify to ignore an empty address taken from a group. While doing this, I
2202 came across some other cases where the code for allowing group syntax
2203 while scanning a header line wasn't quite right (mostly, not resetting
2204 the flag correctly in the right place). These bugs could have caused
2205 trouble for malformed header lines. I hope it is now all correct.

PH
2207PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2209 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2210 but it didn't always do it. This confused somebody who was copying the
2211 code for some other use. I have removed all the tests.

PH
2213PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2214 feature that was used to support insecure browsers during the U.S. crypto
2215 embargo. It requires special client support, and Exim is probably the
2216 only MTA that supported it -- and would never use it because real RSA is
2217 always available. This code has been removed, because it had the bad
2218 effect of slowing Exim down by computing (never used) parameters for the
2219 RSA_EXPORT functionality.

2225 if the connection is using TLS or if the remote IP is the same as the
2226 local IP, and the "valid-client-cert option" if a client certificate has

PH
2258
2259PH/30 Exim was sometimes attempting to deliver messages that had suffered
2260 address errors (4xx response to RCPT) over the same connection as other
2261 messages routed to the same hosts. Such deliveries are always "forced",
2262 so retry times are not inspected. This resulted in far too many retries
2263 for the affected addresses. The effect occurred only when there were more
2264 hosts than the hosts_max_try setting in the smtp transport when it had
2265 the 4xx errors. Those hosts that it had tried were not added to the list
2266 of hosts for which the message was waiting, so if all were tried, there
2267 was no problem. Two fixes have been applied:
2268
2269 (i) If there are any address or message errors in an SMTP delivery, none
2270 of the hosts (tried or untried) are now added to the list of hosts
2271 for which the message is waiting, so the message should not be a
2272 candidate for sending over the same connection that was used for a
2273 successful delivery of some other message. This seems entirely
2274 reasonable: after all the message is NOT "waiting for some host".
2275 This is so "obvious" that I'm not sure why it wasn't done
2276 previously. Hope I haven't missed anything, but it can't do any
2277 harm, as the worst effect is to miss an optimization.
2278
2279 (ii) If, despite (i), such a delivery is accidentally attempted, the
2280 routing retry time is respected, so at least it doesn't keep
2281 hammering the server.

2296PH/35 The error "getsockname() failed: connection reset by peer" was being
2297 written to the panic log as well as the main log, but it isn't really

2299 removed the panic log writing for the ECONNRESET error when getsockname()
2300 fails.

48c7f9e2
PH
2302PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2303 runs only) independently of the message's sender address. This meant
2304 that, if the 4xx error was in fact related to the sender, a different
2305 message to the same recipient with a different sender could confuse
2306 things. In particualar, this can happen when sending to a greylisting
2307 server, but other circumstances could also provoke similar problems.
2308 I have changed the default so that the retry time for these errors is now
2309 based a combination of the sender and recipient addresses. This change
2310 can be overridden by setting address_retry_include_sender=false in the
2311 smtp transport.

2579PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2581 Unfortunately, if there is a major crisis, such as a disk failure,
2582 tcp-wrappers gives "deny", whereas what one would like would be some
2583 kind of temporary error. A kludge has been added to help with this.
2584 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2585 554 error is used if errno is still zero or contains ENOENT (which occurs
2586 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2626 code found IPv4 interfaces correctly, but gave incorrect values for the
2627 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2672 autoreply, Exim could try to deliver to a non-existent relative file

2709 major problems that occur when a DNS server includes only records of one
2710 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2711 fixed another bug: if SRV records were looked up and the corresponding
2712 address records were *not* found in the additional section, the port
2713 values from the SRV records were lost.

2723PH/19 When calculating a retry time, Exim used to measure the "time since
2724 failure" by looking at the "first failed" field in the retry record. Now
2725 it does not use this if it is later than than the arrival time of the
2726 message. Instead it uses the arrival time. This makes for better
2727 behaviour in cases where some deliveries succeed, thus re-setting the
2728 "first failed" field. An example is a quota failure for a huge message
2729 when small messages continue to be delivered. Without this change, the
2730 "time since failure" will always be short, possible causing more frequent
2731 delivery attempts for the huge message than are intended.

PH
2828PH/42 The content-scanning code uses fopen() to create files in which to put
2829 message data. Previously it was not paying any attention to the mode of
2830 the files. Exim runs with umask(0) because the rest of the code creates
2831 files with open(), and sets the required mode explicitly. Thus, these
2832 files were ending up world-writeable. This was not a big issue, because,
2833 being within the spool directory, they were not world-accessible. I have
2834 created a function called modefopen, which takes an additional mode
2835 argument. It sets umask(777), creates the file, chmods it to the required
2836 mode, then resets the umask. All the relevant calls to fopen() in the
2837 content scanning code have been changed to use this function.

2872PH/52 Two bugs concerned with error handling when the smtp transport is

2874
2875 (i) Exim was not creating retry information for temporary errors given
2876 for individual recipients after the DATA command when the smtp transport
2877 was used in LMTP mode. This meant that they could be retried too
2878 frequently, and not timed out correctly.
2879
2880 (ii) Exim was setting the flag that allows error details to be returned
2881 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2882 recipients that were returned after the DATA command.
2883
2884PH/53 This is related to PH/52, but is more general: for any failing address,
2885 when detailed error information was permitted to be returned to the
2886 sender, but the error was temporary, then after the final timeout, only
2887 "retry timeout exceeded" was returned. Now it returns the full error as

2958PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2959 function verify_get_ident() calls ip_connect() to connect a socket, but
2960 if the "connect()" function timed out, ip_connect() used to close the
2961 socket. However, verify_get_ident() also closes the socket later, and in
2962 between Exim writes to the log, which may get opened at this point. When
2963 the socket was closed in ip_connect(), the log could get the same file
2964 descriptor number as the socket. This naturally causes chaos. The fix is
2965 not to close the socket in ip_connect(); the socket should be closed by
2966 the function that creates it. There was only one place in the code where
2967 this was missing, in the iplookup router, which I don't think anybody now
2968 uses, but I've fixed it anyway.

3028 identical. For example:
3029
3030 Received: from [1.2.3.4] (helo=[1.2.3.4])
3031
3032 However, if the real host name was known, it was omitting the HELO data

3126 addresses acquired from the DNS when checking that the found name did
3127 have the original IP as one of its addresses. Since any found IPv6
3128 addresses are likely to be in abbreviated form, the comparison could
3129 fail. Luckily, there already exists a function for doing the comparison
3130 by converting both addresses to binary, so now that is used instead of
3131 the text comparison.

PH
3133PH/20 There was another similar case to PH/19, when a complete host name was
3134 given in a host list; looking up its IP address could give an abbreviated
3135 form, whereas the current host's name might or might not be abbreviated.
3136 The same fix has been applied.

3151PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
3152 header line, restrict the check to what is listed in RFCs 2369 and 2929.
3153 Also, for "Auto-Submitted", treat anything other than "no" as
3154 non-personal, in accordance with RFC 3834. (Previously it treated
3155 anything starting "auto-" as non-personal.)

3157TF/01 The control=submission/name=... option had a problem with syntax
3158 errors if the name included a slash character. The /name= option
3159 now slurps the rest of the string, so it can include any characters

3178PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of

3184 referenced, not the Message-ID: header line.

3210PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3211 run a filter in a subprocess. This could lead to confusion in subsequent
3212 lookups in the parent process. There should also be a search_tidyup() at
3213 the end of the subprocess.

PH
3215PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3216 only if the host matched helo_try_verify_hosts, which caused the
3217 verification to occur when the EHLO/HELO command was issued. The ACL just
3218 tested the remembered result. Now, if a previous verification attempt has
3219 not happened, "verify = helo" does it there and then.

3248PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3249 authentication with radiusclient 0.4.9:
3250
3251 - Error returned from rc_read_config was caught wrongly
3252 - Username/password not passed on to radius server due to wrong length.
3253
3254 The presumption is that some radiusclient API changes for 4.51/PH/17
3255 were not taken care of correctly. The code is still untested by me (my
3256 Linux distribution still has 0.3.2 of radiusclient), but it was
3257 contributed by a Radius user.
