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).

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
35JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
36 and 3.4.4 - once the server is enabled to respond to an OCSP request
37 it does even when not requested, resulting in a stapling non-aware
38 client dropping the TLS connection.

40TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
41 support variable-length bit vectors. No functional change.
42

TF
43TF/02 Improve the consistency of logging incoming and outgoing interfaces.
44 The I= interface field on outgoing lines is now after the H= remote
45 host field, same as incoming lines. There is a separate
46 outgoing_interface log selector which allows you to disable the
47 outgoing I= field.
48
c8899c20
JH
49JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
50 If not running log_selector +smtp_connection the mainlog would be held
51 open indefinitely after a "too many connections" event, including to a
52 deleted file after a log rotate. Leave the per net connection logging
53 leaving it open for efficiency as that will be quickly detected by the
54 check on the next write.

56HS/01 Bug 1671: Fix post transport crash.
57 Processing the wait-<transport> messages could crash the delivery
58 process if the message IDs didn't exist for some reason. When
59 using 'split_spool_directory=yes' the construction of the spool
60 file name failed already, exposing the same netto behaviour.

66 to DSN fail messages (bounces): remote IP, remote greeting, remote response
67 to HELO, local diagnostic string.
68
805bb5c3
JH
69JH/05 Downgrade message for a TLS-certificate-based authentication fail from
70 log line to debug. Even when configured with a tls authenticator many
71 client connections are expected to not authenticate in this way, so
72 an authenticate fail is not an error.

75 gives some more detail about the running daemon.

77JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
78 matter for fast-change records such as DNSBLs.
79
6f6dedcc
JH
80JH/07 Bug 1678: Always record an interface option value, if set, as part of a

82 different interface settings and the retry behaviour needs to be kept
83 distinct.

108
23f3dc67
JH
109JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
110 defaults to "*" (all hosts). The variable is now available when not built
111 with TLS, default unset, mainly to enable keeping the testuite sane.
112 If a server certificate is not supplied (via tls_certificate) an error is
113 logged, and clients will find TLS connections fail on startup. Presumably
114 they will retry in-clear.
115 Packagers of Exim are strongly encouraged to create a server certificate
116 at installation time.
117
240c288f
JH
118HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
119 with the $config_file variable.

JB
121JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
122 in transport context, after the attempt, and per-recipient. The latter type
123 is per host attempted. The event data is the error message, and the errno
124 information encodes the lookup type (A vs. MX) used for the (first) host,
125 and the trailing two digits of the smtp 4xx reponse.

127GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
128 to write to mainlog (or rejectlog, paniclog) in the window between file
129 creation and permissions/ownership being changed. Particularly affects
130 installations where exicyclog is run as root, rather than exim user;
131 result is that the running daemon panics and dies.

136 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options

138 list order is no longer honoured.

f444c2c7
JH
171JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
172 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
173 only supported when built with TLS support. The PolarSSL SHA routines
174 are still used when the TLS library is too old for convenient support.

a57b6200
JH
176JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
177 openssl_options), for security. OpenSSL forces this from version 1.1.0
178 server-side so match that on older versions.
179
07c73177 180JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 181 allocation for $value could be released as the expansion processing
07c73177 182 concluded, but leaving the global pointer active for it.

185 and to use the domains and local_parts ACL conditions.
186
1bc460a6
JH
187JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
188 incorrectly not doubled on cutthrough transmission, hence seen as a
189 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 190 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
191 via the normal store-and-forward channel. This could result in duplicates
192 received - but deduplicating mailstores were liable to retain only the
193 initial truncated version.

228 extraction. Accept either.

354Exim version 4.85
355-----------------
356TL/01 When running the test suite, the README says that variables such as
357 no_msglog_check are global and can be placed anywhere in a specific
358 test's script, however it was observed that placement needed to be near
359 the beginning for it to behave that way. Changed the runtest perl
360 script to read through the entire script once to detect and set these
361 variables, reset to the beginning of the script, and then run through
362 the script parsing/test process like normal.

719TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
720
721 When a queue runner is handling a message, Exim first routes the
722 recipient addresses, during which it prunes them based on the retry
723 hints database. After that it attempts to deliver the message to
724 any remaining recipients. It then updates the hints database using
725 the retry rules.
726
727 So if a recipient address works intermittently, it can get repeatedly
728 deferred at routing time. The retry hints record remains fresh so the
729 address never reaches the final cutoff time.
730
731 This is a fairly common occurrence when a user is bumping up against
732 their storage quota. Exim had some logic in its local delivery code
733 to deal with this. However it did not apply to per-recipient defers
734 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
735
1ddeb334
TF
736 This change adds a proper retry rule check during routing so that the
737 final cutoff time is checked against the message's age. We only do
738 this check if there is an address retry record and there is not a
739 domain retry record; this implies that previous attempts to handle
740 the address had the retry_use_local_parts option turned on. We use
741 this as an approximation for the destination being like a local
742 delivery, as in LMTP.
67bd1ab3
TF
743
744 I suspect this new check makes the old local delivery cutoff check
745 redundant, but I have not verified this so I left the code in place.

1067TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1068 lock up or crash if it happened to be inside a call to libc when it
1069 got a SIGUSR1 from exiwhat.
1070
1071 The SIGUSR1 handler appends the current process status to the process
1072 log which is later printed by exiwhat. It used to use the general
1073 purpose logging code to do this, but several functions it calls are
1074 not safe for signals.
1075
1076 The new output code in the SIGUSR1 handler is specific to the process
1077 log, and simple enough that it's easy to inspect for signal safety.
1078 Removing some special cases also simplifies the general logging code.
1079 Removing the spurious timestamps from the process log simplifies
1080 exiwhat.
1081
c99ce5c9
TF
1082TF/04 Improved ratelimit ACL condition.
1083
1084 The /noupdate option has been deprecated in favour of /readonly which
1085 has clearer semantics. The /leaky, /strict, and /readonly update modes
1086 are mutually exclusive. The update mode is no longer included in the
1087 database key; it just determines when the database is updated. (This
1088 means that when you upgrde Exim will forget old rate measurements.)
1089
1090 Exim now checks that the per_* options are used with an update mode that
1091 makes sense for the current ACL. For example, when Exim is processing a
1092 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1093 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1094 must specify per_mail/readonly. If you omit the update mode it defaults to
1095 /leaky where that makes sense (as before) or /readonly where required.
1096
1097 The /noupdate option is now undocumented but still supported for
1098 backwards compatibility. It is equivalent to /readonly except that in
1099 ACLs where /readonly is required you may specify /leaky/noupdate or
1100 /strict/noupdate which are treated the same as /readonly.
1101
1102 A useful new feature is the /count= option. This is a generalization
1103 of the per_byte option, so that you can measure the throughput of other
1104 aggregate values. For example, the per_byte option is now equivalent
1105 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1106
1107 The per_rcpt option has been generalized using the /count= mechanism
1108 (though it's more complicated than the per_byte equivalence). When it is
1109 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1110 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1111 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1112 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1113 Note that using per_rcpt with a non-readonly update mode in more than
1114 one ACL will cause the recipients to be double-counted. (The per_mail
1115 and per_byte options don't have this problem.)
1116
1117 The handling of very low rates has changed slightly. If the computed rate
1118 is less than the event's count (usually one) then this event is the first
1119 after a long gap. In this case the rate is set to the same as this event's
1120 count, so that the first message of a spam run is counted properly.
1121
1122 The major new feature is a mechanism for counting the rate of unique
1123 events. The new per_addr option counts the number of different
1124 recipients that someone has sent messages to in the last time period. It
1125 behaves like per_rcpt if all the recipient addresses are different, but
1126 duplicate recipient addresses do not increase the measured rate. Like
1127 the /count= option this is a general mechanism, so the per_addr option
1128 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1129 example, measure the rate that a client uses different sender addresses
1130 with the options per_mail/unique=$sender_address. There are further
1131 details in the main documentation.

1700Exim version 4.68
1701-----------------
1702
1703PH/01 Another patch from the Sieve maintainer.
1704
6a3bceb1
PH
1705PH/02 When an IPv6 address is converted to a string for single-key lookup
1706 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1707 dots are used instead of colons so that keys in lsearch files need not
1708 contain colons. This was done some time before quoting was made available
1709 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1710 (notated using the quote facility) so as to distinguish them from IPv4
1711 keys. This meant that lookups for IP addresses in host lists did not work
1712 for iplsearch lookups.
1713
1714 This has been fixed by arranging for IPv6 addresses to be expressed with
1715 colons if the lookup type is iplsearch. This is not incompatible, because
1716 previously such lookups could never work.
1717
1718 The situation is now rather anomolous, since one *can* have colons in
1719 ordinary lsearch keys. However, making the change in all cases is
1720 incompatible and would probably break a number of configurations.
1721

MH
1725MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1726 conversion specification without a maximum field width, thereby enabling
1727 a rogue spamd server to cause a buffer overflow. While nobody in their
1728 right mind would setup Exim to query an untrusted spamd server, an
1729 attacker that gains access to a server running spamd could potentially
1730 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1735MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1736 a directory entry by the name of the lookup key. Previously, if a
1737 symlink pointed to a non-existing file or a file in a directory that
1738 Exim lacked permissions to read, a lookup for a key matching that
1739 symlink would fail. Now it is enough that a matching directory entry
1740 exists, symlink or not. (Bugzilla 503.)

1817 if a client was not listed at all, or was listed with a value other than
1818 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1819 the condition was not true (as it should be), so access was not denied.

1923PH/29 SMTP synchronization checks are implemented when a command is read -
1924 there is a check that no more input is waiting when there shouldn't be

1926 some time before the response is written. In this time, more input might
1927 arrive, invalidly. So now there are extra checks after an ACL has run for
1928 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1929 pipelining has not been advertised.

1945 was a macro that became an assignment, so it seemed to work. This has
1946 changed to a proper function call with a void return, hence the compile
1947 error. Exim's code has been fixed.

2005 (unfortunately, this is allowed). However, in many cases there won't be
2006 any further data because there won't be any more messages to send. A call
2007 to select() can be used: if it shows that the input is "ready", there is
2008 either input waiting, or the socket has been closed. An attempt to read
2009 the next input character can distinguish the two cases. Previously, Exim

2021PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2022 fixed by 4.65/MH/01 (is this a record?) are fixed:
2023
2024 (i) An empty string was always treated as zero by the numeric comparison
2025 operators. This behaviour has been restored.
2026
2027 (ii) It is documented that the numeric comparison operators always treat
2028 their arguments as decimal numbers. This was broken in that numbers
2029 starting with 0 were being interpreted as octal.
2030
2031 While fixing these problems I realized that there was another issue that
2032 hadn't been noticed. Values of message_size_limit (both the global option
2033 and the transport option) were treated as octal if they started with 0.
2034 The documentation was vague. These values are now always treated as
2035 decimal, and I will make that clear in the documentation.

2052 large number of recipients for a single message is ridiculous
2053 (performance will be very, very poor), I have chosen to impose a limit
2054 rather than extend the field.

PH
2079PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2080 callout verification, Exim cached a "reject" for the entire domain. This
2081 is correct for most verifications, but it is not correct for a recipient
2082 verification with use_sender or use_postmaster set, because in that case
2083 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2084 case of MAIL FROM:<> rejection from other early rejections (e.g.
2085 rejection of HELO). When verifying a recipient using a non-null MAIL
2086 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2087 Whatever the result of the callout, the value of the domain cache is
2088 left unchanged (for any other kind of callout, getting as far as trying
2089 RCPT means that the domain itself is ok).

2125 probably the interface on which it is arriving) and not to the outgoing
2126 callout (which could be using a different interface). This has been
2127 changed to use the value of the helo_data option from the smtp transport
2128 instead - this is what is used when a message is actually being sent. If
2129 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
2134 (a) The code assumed that strncpy() returns a negative number on buffer
2135 overflow, which isn't the case. Replaced with Exim's string_format()
2136 function.
2137 (b) There were several signed/unsigned issues. I just did the minimum
2138 hacking in of casts. There is scope for a larger refactoring.
2139 (c) The code used strcasecmp() which is not a standard C function.
2140 Replaced with Exim's strcmpic() function.
2141 (d) The code set only $1; it now sets $auth1 as well.
2142 (e) A simple test gave the error "authentication client didn't specify
2143 service in request". It would seem that Dovecot has changed its
2144 interface. Fortunately there's a specification; I followed it and
2145 changed what the client sends and it appears to be working now.

2151 address A is aliased to B and C, where B exists and C does not. Without
2152 -v the output is "A verified" because verification stops after a
2153 successful redirection if more than one address is generated. However,
2154 with -v the child addresses are also verified. Exim was outputting "A
2155 failed to verify" and then showing the successful verification for C,
2156 with its parentage. It now outputs "B failed to verify", showing B's
2157 parentage before showing the successful verification of C.

PH
2163PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2164 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2165 they consult the DNS. I had assumed they would set it the way they
2166 wanted; and indeed my experiments on Linux seem to show that in some
2167 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2168 To be on the safe side, however, I have now made the interface to
2169 host_find_byname() similar to host_find_bydns(), with an argument
2170 containing the DNS resolver options. The host_find_byname() function now
2171 sets these options at its start, just as host_find_bydns() does. The smtp
2172 transport options dns_qualify_single and dns_search_parents are passed to
2173 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2174 of host_find_byname() use the default settings of RES_DEFNAMES
2175 (qualify_single) but not RES_DNSRCH (search_parents).

2177PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2178 spool_read_header() do less string testing, by means of a preliminary
2179 switch on the second character of optional "-foo" lines. (This is
2180 overdue, caused by the large number of possibilities that now exist.
2181 Originally there were few.) While I was there, I also converted the
2182 str(n)cmp tests so they don't re-test the leading "-" and the first
2183 character, in the hope this might squeeze out yet more improvement.

2185PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2186 flag allowing group syntax was set by the header_syntax check but not
2187 turned off, possible causing trouble later; (2) The flag was not being
2188 set at all for the header_verify test, causing "group"-style headers to
2189 be rejected. I have now set it in this case, and also caused header_
2190 verify to ignore an empty address taken from a group. While doing this, I
2191 came across some other cases where the code for allowing group syntax
2192 while scanning a header line wasn't quite right (mostly, not resetting
2193 the flag correctly in the right place). These bugs could have caused
2194 trouble for malformed header lines. I hope it is now all correct.

PH
2196PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2197 with the "reply" argument non-NULL. The code, however (which originally
2198 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2199 but it didn't always do it. This confused somebody who was copying the
2200 code for some other use. I have removed all the tests.

PH
2202PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2203 feature that was used to support insecure browsers during the U.S. crypto
2204 embargo. It requires special client support, and Exim is probably the
2205 only MTA that supported it -- and would never use it because real RSA is
2206 always available. This code has been removed, because it had the bad
2207 effect of slowing Exim down by computing (never used) parameters for the
2208 RSA_EXPORT functionality.

2213 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2214 if the connection is using TLS or if the remote IP is the same as the
2215 local IP, and the "valid-client-cert option" if a client certificate has
2216 been verified.

2247
2248PH/30 Exim was sometimes attempting to deliver messages that had suffered
2249 address errors (4xx response to RCPT) over the same connection as other
2250 messages routed to the same hosts. Such deliveries are always "forced",
2251 so retry times are not inspected. This resulted in far too many retries
2252 for the affected addresses. The effect occurred only when there were more
2253 hosts than the hosts_max_try setting in the smtp transport when it had
2254 the 4xx errors. Those hosts that it had tried were not added to the list
2255 of hosts for which the message was waiting, so if all were tried, there
2256 was no problem. Two fixes have been applied:
2257
2258 (i) If there are any address or message errors in an SMTP delivery, none
2259 of the hosts (tried or untried) are now added to the list of hosts
2260 for which the message is waiting, so the message should not be a
2261 candidate for sending over the same connection that was used for a
2262 successful delivery of some other message. This seems entirely
2263 reasonable: after all the message is NOT "waiting for some host".
2264 This is so "obvious" that I'm not sure why it wasn't done
2265 previously. Hope I haven't missed anything, but it can't do any
2266 harm, as the worst effect is to miss an optimization.
2267
2268 (ii) If, despite (i), such a delivery is accidentally attempted, the
2269 routing retry time is respected, so at least it doesn't keep
2270 hammering the server.

2285PH/35 The error "getsockname() failed: connection reset by peer" was being
2286 written to the panic log as well as the main log, but it isn't really
2287 panic-worthy as it just means the connection died rather early on. I have
2288 removed the panic log writing for the ECONNRESET error when getsockname()
2289 fails.
2290
48c7f9e2
PH
2291PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2292 runs only) independently of the message's sender address. This meant
2293 that, if the 4xx error was in fact related to the sender, a different
2294 message to the same recipient with a different sender could confuse
2295 things. In particualar, this can happen when sending to a greylisting
2296 server, but other circumstances could also provoke similar problems.
2297 I have changed the default so that the retry time for these errors is now
2298 based a combination of the sender and recipient addresses. This change
2299 can be overridden by setting address_retry_include_sender=false in the
2300 smtp transport.

2568PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2570 Unfortunately, if there is a major crisis, such as a disk failure,
2571 tcp-wrappers gives "deny", whereas what one would like would be some
2572 kind of temporary error. A kludge has been added to help with this.
2573 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2574 554 error is used if errno is still zero or contains ENOENT (which occurs
2575 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2576 451 error is used.

2616 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2661 autoreply, Exim could try to deliver to a non-existent relative file

2686 suitable debugging ouput when -d is set.

2690 the subprocess without attempting to change uid/gid.

2696 additional section of a DNS packet that returns MX or SRV records.
2697 Instead, it always explicitly searches for A/AAAA records. This avoids
2698 major problems that occur when a DNS server includes only records of one
2699 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2700 fixed another bug: if SRV records were looked up and the corresponding
2701 address records were *not* found in the additional section, the port
2702 values from the SRV records were lost.

2704PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2711
727071f8
PH
2712PH/19 When calculating a retry time, Exim used to measure the "time since
2713 failure" by looking at the "first failed" field in the retry record. Now
2714 it does not use this if it is later than than the arrival time of the
2715 message. Instead it uses the arrival time. This makes for better
2716 behaviour in cases where some deliveries succeed, thus re-setting the
2717 "first failed" field. An example is a quota failure for a huge message
2718 when small messages continue to be delivered. Without this change, the

PH
2817PH/42 The content-scanning code uses fopen() to create files in which to put
2818 message data. Previously it was not paying any attention to the mode of
2819 the files. Exim runs with umask(0) because the rest of the code creates
2820 files with open(), and sets the required mode explicitly. Thus, these
2821 files were ending up world-writeable. This was not a big issue, because,
2822 being within the spool directory, they were not world-accessible. I have
2823 created a function called modefopen, which takes an additional mode
2824 argument. It sets umask(777), creates the file, chmods it to the required
2825 mode, then resets the umask. All the relevant calls to fopen() in the
2826 content scanning code have been changed to use this function.

2835 challenges are checked to ensure they are valid base64 strings. By
2836 default, the authentication attempt is cancelled if an invalid string is
2837 received. Setting client_ignore_invalid_base64 true ignores these errors.
2838 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2839 they are received. Thus, the responses can be made to depend on the
2840 challenges. If an invalid string is ignored, an empty string is placed in
2841 the variable.

2861PH/52 Two bugs concerned with error handling when the smtp transport is
2862 used in LMTP mode:
2863
2864 (i) Exim was not creating retry information for temporary errors given
2865 for individual recipients after the DATA command when the smtp transport
2866 was used in LMTP mode. This meant that they could be retried too
2867 frequently, and not timed out correctly.
2868
2869 (ii) Exim was setting the flag that allows error details to be returned
2870 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2871 recipients that were returned after the DATA command.
2872
2873PH/53 This is related to PH/52, but is more general: for any failing address,
2874 when detailed error information was permitted to be returned to the
2875 sender, but the error was temporary, then after the final timeout, only
2876 "retry timeout exceeded" was returned. Now it returns the full error as
2877 well as "retry timeout exceeded".

PH
2947PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2948 function verify_get_ident() calls ip_connect() to connect a socket, but
2949 if the "connect()" function timed out, ip_connect() used to close the
2950 socket. However, verify_get_ident() also closes the socket later, and in
2951 between Exim writes to the log, which may get opened at this point. When
2952 the socket was closed in ip_connect(), the log could get the same file
2953 descriptor number as the socket. This naturally causes chaos. The fix is
2954 not to close the socket in ip_connect(); the socket should be closed by
2955 the function that creates it. There was only one place in the code where
2956 this was missing, in the iplookup router, which I don't think anybody now
2957 uses, but I've fixed it anyway.

2980
2981 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2983
2984 (3) Reset the variables that are obtained from the first argument of
2985 ${prvscheck and used in the second argument before leaving the code,
2986 because their memory is reclaimed, so using them afterwards may do
2987 silly things.
2988
2989 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2990 one (it's much easier than Tom thought :-).

3014 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3015 not being looked up in the rDNS to get a host name, Exim was showing the
3016 IP address twice in Received: lines, even though the IP addresses were
3017 identical. For example:
3018
3019 Received: from [1.2.3.4] (helo=[1.2.3.4])
3020
3021 However, if the real host name was known, it was omitting the HELO data

3023 doesn't show the same IP address twice.

3115 addresses acquired from the DNS when checking that the found name did
3116 have the original IP as one of its addresses. Since any found IPv6
3117 addresses are likely to be in abbreviated form, the comparison could
3118 fail. Luckily, there already exists a function for doing the comparison
3119 by converting both addresses to binary, so now that is used instead of
3120 the text comparison.

3131PH/01 The ${base62: operator adjusted itself to base 36 when BASE_62 was
3132 set to 36 (for Darwin and Cygwin), but the ${base62d: operator did not.
3133 It now does.

3135PH/02 Two minor problems detected in Cygwin: the os.{c,h} files had lost */ on
3136 the CVS lines, and there was a missing #if HAVE_IPV6 in host.c.

3138PH/03 Typo: missing ".o" in src/pcre/Makefile.

PH
3140PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
3141 header line, restrict the check to what is listed in RFCs 2369 and 2929.
3142 Also, for "Auto-Submitted", treat anything other than "no" as
3143 non-personal, in accordance with RFC 3834. (Previously it treated
3144 anything starting "auto-" as non-personal.)

3146TF/01 The control=submission/name=... option had a problem with syntax
3147 errors if the name included a slash character. The /name= option
3148 now slurps the rest of the string, so it can include any characters
3149 but it must come last in the list of options (after /sender_retain
3150 or /domain=).

PH
3167PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
3168 fread() to skip over the body file's header line, because in Cygwin the
3169 header line is locked and is inaccessible.

1ab52c69
PH
3171PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
3172 co-exist for some time) to make it clear that it is the Exim ID that is
3173 referenced, not the Message-ID: header line.

b07e6aa3
PH
3175PH/05 Replaced all Tom's calls to snprintf() with calls to the internal
3176 string_format() function, because snprintf() does not exist on all
3177 operating systems.

PH
3179PH/06 The use of forbid_filter_existstest now also locks out the use of the

PH
3199PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3200 run a filter in a subprocess. This could lead to confusion in subsequent
3201 lookups in the parent process. There should also be a search_tidyup() at
3202 the end of the subprocess.

PH
3204PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3205 only if the host matched helo_try_verify_hosts, which caused the
3206 verification to occur when the EHLO/HELO command was issued. The ACL just
3207 tested the remembered result. Now, if a previous verification attempt has
3208 not happened, "verify = helo" does it there and then.

3227PH/20 If a delivery was routed to a non-standard port by means of an SRV
3228 record, the port was not correctly logged when the outgoing_port log
3229 selector was set (it logged the transort's default port).

PH
3237PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3238 authentication with radiusclient 0.4.9:
3239
3240 - Error returned from rc_read_config was caught wrongly
3241 - Username/password not passed on to radius server due to wrong length.
3242
3243 The presumption is that some radiusclient API changes for 4.51/PH/17
3244 were not taken care of correctly. The code is still untested by me (my
3245 Linux distribution still has 0.3.2 of radiusclient), but it was
3246 contributed by a Radius user.

3261PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
3262 commands, but it was not correctly comparing the address with the actual
3263 client host address. Thus, it would show the EHLO address in Received:
3264 header lines when this was not necessary.

PH
3268PH/28 Exim tries to create and chdir to its spool directory when it starts;
3269 it should be ignoring failures (because with -C, for example, it has lost

3271 exists".

3289PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
3290 Local/Makefile (with some defaults set). These are used in built scripts
3291 such as exicyclog, but they have never been used in the exim_install
3292 script (though there are many overriding facilities there). I have

3298PH/36 When a locally submitted message by a trusted user did not contain a
3299 From: header, and the sender address was obtained from -f or from an SMTP
3300 MAIL command, and the trusted user did not use -F to supply a sender
3301 name, $originator_name was incorrectly used when constructing a From:
3302 header. Furthermore, $originator_name was used for submission mode
3303 messages from external hosts without From: headers in a similar way,
3304 which is clearly wrong.
