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).

9JH/02 The obsolete acl condition "demime" is removed (finally, after ten
10 years of being deprecated). The replacements are the ACLs

JH
16JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
17 and 3.4.4 - once the server is enabled to respond to an OCSP request
18 it does even when not requested, resulting in a stapling non-aware
19 client dropping the TLS connection.

21TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
22 support variable-length bit vectors. No functional change.
23

TF
24TF/02 Improve the consistency of logging incoming and outgoing interfaces.
25 The I= interface field on outgoing lines is now after the H= remote
26 host field, same as incoming lines. There is a separate
27 outgoing_interface log selector which allows you to disable the
28 outgoing I= field.

JH
30JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
31 If not running log_selector +smtp_connection the mainlog would be held
32 open indefinitely after a "too many connections" event, including to a
33 deleted file after a log rotate. Leave the per net connection logging
34 leaving it open for efficiency as that will be quickly detected by the
35 check on the next write.

37HS/01 Bug 1671: Fix post transport crash.
38 Processing the wait-<transport> messages could crash the delivery
39 process if the message IDs didn't exist for some reason. When
40 using 'split_spool_directory=yes' the construction of the spool
41 file name failed already, exposing the same netto behaviour.

48 to HELO, local diagnostic string.
49
805bb5c3
JH
50JH/05 Downgrade message for a TLS-certificate-based authentication fail from
51 log line to debug. Even when configured with a tls authenticator many
52 client connections are expected to not authenticate in this way, so
53 an authenticate fail is not an error.

56 gives some more detail about the running daemon.

58JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
59 matter for fast-change records such as DNSBLs.
60
6f6dedcc
JH
61JH/07 Bug 1678: Always record an interface option value, if set, as part of a
62 retry record, even if constant. There may be multiple transports with
63 different interface settings and the retry behaviour needs to be kept
64 distinct.

73 hosts_randomize. This matters a lot when combined with mua_wrapper.

88JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
89
23f3dc67
JH
90JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
91 defaults to "*" (all hosts). The variable is now available when not built
92 with TLS, default unset, mainly to enable keeping the testuite sane.
93 If a server certificate is not supplied (via tls_certificate) an error is
94 logged, and clients will find TLS connections fail on startup. Presumably
95 they will retry in-clear.
96 Packagers of Exim are strongly encouraged to create a server certificate
97 at installation time.
98
240c288f
JH
99HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
100 with the $config_file variable.
101
5ef5dd52
JB
102JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
103 in transport context, after the attempt, and per-recipient. The latter type
104 is per host attempted. The event data is the error message, and the errno
105 information encodes the lookup type (A vs. MX) used for the (first) host,
106 and the trailing two digits of the smtp 4xx reponse.
107
e161710d
GF
108GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
109 to write to mainlog (or rejectlog, paniclog) in the window between file
110 creation and permissions/ownership being changed. Particularly affects
111 installations where exicyclog is run as root, rather than exim user;
112 result is that the running daemon panics and dies.

117 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
118 "pri" and "weight". Note that the previous implicit priority given by the
119 list order is no longer honoured.

127JH/26 Move PROXY support from Experimental to mainline, enabled for a build
128 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989

150 keys are given for lookup.

f444c2c7
JH
152JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
153 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
154 only supported when built with TLS support. The PolarSSL SHA routines
155 are still used when the TLS library is too old for convenient support.
f444c2c7 156
a57b6200
JH
157JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
158 openssl_options), for security. OpenSSL forces this from version 1.1.0
159 server-side so match that on older versions.
160
07c73177 161JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 162 allocation for $value could be released as the expansion processing
07c73177 163 concluded, but leaving the global pointer active for it.
fa01e4f8 164

165JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
166 and to use the domains and local_parts ACL conditions.
167
1bc460a6
JH
168JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
169 incorrectly not doubled on cutthrough transmission, hence seen as a
170 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 171 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
172 via the normal store-and-forward channel. This could result in duplicates
173 received - but deduplicating mailstores were liable to retain only the
174 initial truncated version.
175

206JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
207 an extract embedded as result-arg for a map, the first arg for extract
208 is unavailable so we cannot tell if this is a numbered or keyed
209 extraction. Accept either.

335Exim version 4.85
336-----------------
337TL/01 When running the test suite, the README says that variables such as
338 no_msglog_check are global and can be placed anywhere in a specific
339 test's script, however it was observed that placement needed to be near
340 the beginning for it to behave that way. Changed the runtest perl
341 script to read through the entire script once to detect and set these
342 variables, reset to the beginning of the script, and then run through
343 the script parsing/test process like normal.

370JH/05 Fix results-pipe from transport process. Several recipients, combined
371 with certificate use, exposed issues where response data items split
372 over buffer boundaries were not parsed properly. This eventually
373 resulted in duplicates being sent. This issue only became common enough

700TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
701
702 When a queue runner is handling a message, Exim first routes the
703 recipient addresses, during which it prunes them based on the retry
704 hints database. After that it attempts to deliver the message to
705 any remaining recipients. It then updates the hints database using
706 the retry rules.
707
708 So if a recipient address works intermittently, it can get repeatedly
709 deferred at routing time. The retry hints record remains fresh so the
710 address never reaches the final cutoff time.
711
712 This is a fairly common occurrence when a user is bumping up against
713 their storage quota. Exim had some logic in its local delivery code
714 to deal with this. However it did not apply to per-recipient defers
715 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
716
1ddeb334
TF
717 This change adds a proper retry rule check during routing so that the
718 final cutoff time is checked against the message's age. We only do
719 this check if there is an address retry record and there is not a
720 domain retry record; this implies that previous attempts to handle
721 the address had the retry_use_local_parts option turned on. We use
722 this as an approximation for the destination being like a local
723 delivery, as in LMTP.
67bd1ab3
TF
724
725 I suspect this new check makes the old local delivery cutoff check
726 redundant, but I have not verified this so I left the code in place.

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

1048TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1049 lock up or crash if it happened to be inside a call to libc when it
1050 got a SIGUSR1 from exiwhat.
1051
1052 The SIGUSR1 handler appends the current process status to the process
1053 log which is later printed by exiwhat. It used to use the general
1054 purpose logging code to do this, but several functions it calls are
1055 not safe for signals.
1056
1057 The new output code in the SIGUSR1 handler is specific to the process
1058 log, and simple enough that it's easy to inspect for signal safety.
1059 Removing some special cases also simplifies the general logging code.
1060 Removing the spurious timestamps from the process log simplifies
1061 exiwhat.
1062

TF
1063TF/04 Improved ratelimit ACL condition.
1064
1065 The /noupdate option has been deprecated in favour of /readonly which
1066 has clearer semantics. The /leaky, /strict, and /readonly update modes
1067 are mutually exclusive. The update mode is no longer included in the
1068 database key; it just determines when the database is updated. (This
1069 means that when you upgrde Exim will forget old rate measurements.)
1070
1071 Exim now checks that the per_* options are used with an update mode that
1072 makes sense for the current ACL. For example, when Exim is processing a
1073 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1074 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1075 must specify per_mail/readonly. If you omit the update mode it defaults to
1076 /leaky where that makes sense (as before) or /readonly where required.
1077
1078 The /noupdate option is now undocumented but still supported for
1079 backwards compatibility. It is equivalent to /readonly except that in
1080 ACLs where /readonly is required you may specify /leaky/noupdate or
1081 /strict/noupdate which are treated the same as /readonly.
1082
1083 A useful new feature is the /count= option. This is a generalization
1084 of the per_byte option, so that you can measure the throughput of other
1085 aggregate values. For example, the per_byte option is now equivalent
1086 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1087
1088 The per_rcpt option has been generalized using the /count= mechanism
1089 (though it's more complicated than the per_byte equivalence). When it is
1090 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1091 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1092 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1093 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1094 Note that using per_rcpt with a non-readonly update mode in more than
1095 one ACL will cause the recipients to be double-counted. (The per_mail
1096 and per_byte options don't have this problem.)
1097
1098 The handling of very low rates has changed slightly. If the computed rate
1099 is less than the event's count (usually one) then this event is the first
1100 after a long gap. In this case the rate is set to the same as this event's
1101 count, so that the first message of a spam run is counted properly.
1102
1103 The major new feature is a mechanism for counting the rate of unique
1104 events. The new per_addr option counts the number of different
1105 recipients that someone has sent messages to in the last time period. It
1106 behaves like per_rcpt if all the recipient addresses are different, but
1107 duplicate recipient addresses do not increase the measured rate. Like
1108 the /count= option this is a general mechanism, so the per_addr option
1109 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1110 example, measure the rate that a client uses different sender addresses
1111 with the options per_mail/unique=$sender_address. There are further
1112 details in the main documentation.

1194 cause arbitrary Exim lookups (of items which can occur in lists, *not*
1195 arbitrary string expansion). This allowed for information disclosure.

1662 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1663 were called 'true' and it seems that C99 defines that as a reserved
1664 keyword to be used with 'bool' variable types. That means you could
1665 not include C99-style headers which use bools without triggering

1681Exim version 4.68
1682-----------------
1683
1684PH/01 Another patch from the Sieve maintainer.
1685
6a3bceb1
PH
1686PH/02 When an IPv6 address is converted to a string for single-key lookup
1687 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1688 dots are used instead of colons so that keys in lsearch files need not
1689 contain colons. This was done some time before quoting was made available
1690 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1691 (notated using the quote facility) so as to distinguish them from IPv4
1692 keys. This meant that lookups for IP addresses in host lists did not work
1693 for iplsearch lookups.
1694
1695 This has been fixed by arranging for IPv6 addresses to be expressed with
1696 colons if the lookup type is iplsearch. This is not incompatible, because
1697 previously such lookups could never work.
1698
1699 The situation is now rather anomolous, since one *can* have colons in
1700 ordinary lsearch keys. However, making the change in all cases is
1701 incompatible and would probably break a number of configurations.
1702

MH
1706MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1707 conversion specification without a maximum field width, thereby enabling
1708 a rogue spamd server to cause a buffer overflow. While nobody in their
1709 right mind would setup Exim to query an untrusted spamd server, an
1710 attacker that gains access to a server running spamd could potentially
1711 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1716MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1717 a directory entry by the name of the lookup key. Previously, if a
1718 symlink pointed to a non-existing file or a file in a directory that
1719 Exim lacked permissions to read, a lookup for a key matching that
1720 symlink would fail. Now it is enough that a matching directory entry
1721 exists, symlink or not. (Bugzilla 503.)

1798 if a client was not listed at all, or was listed with a value other than
1799 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

1904PH/29 SMTP synchronization checks are implemented when a command is read -
1905 there is a check that no more input is waiting when there shouldn't be
1906 any. However, for some commands, a delay in an ACL can mean that it is
1907 some time before the response is written. In this time, more input might
1908 arrive, invalidly. So now there are extra checks after an ACL has run for
1909 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1910 pipelining has not been advertised.

1922PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1925 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1926 was a macro that became an assignment, so it seemed to work. This has

1928 error. Exim's code has been fixed.

1959 started the daemon, but after a SIGHUP it used the Exim user (because it

1966 with PIPELINING or a stupid MUA), the error message that was given to the

1984 the response to the final '.' that terminates a message, but only in the
1985 case where the client has not sent further data following the '.'
1986 (unfortunately, this is allowed). However, in many cases there won't be
1987 any further data because there won't be any more messages to send. A call
1988 to select() can be used: if it shows that the input is "ready", there is
1989 either input waiting, or the socket has been closed. An attempt to read
1990 the next input character can distinguish the two cases. Previously, Exim

2002PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2003 fixed by 4.65/MH/01 (is this a record?) are fixed:
2004
2005 (i) An empty string was always treated as zero by the numeric comparison
2006 operators. This behaviour has been restored.
2007
2008 (ii) It is documented that the numeric comparison operators always treat
2009 their arguments as decimal numbers. This was broken in that numbers
2010 starting with 0 were being interpreted as octal.
2011
2012 While fixing these problems I realized that there was another issue that
2013 hadn't been noticed. Values of message_size_limit (both the global option
2014 and the transport option) were treated as octal if they started with 0.
2015 The documentation was vague. These values are now always treated as
2016 decimal, and I will make that clear in the documentation.

2033 large number of recipients for a single message is ridiculous
2034 (performance will be very, very poor), I have chosen to impose a limit

PH
2060PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2061 callout verification, Exim cached a "reject" for the entire domain. This
2062 is correct for most verifications, but it is not correct for a recipient
2063 verification with use_sender or use_postmaster set, because in that case
2064 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2065 case of MAIL FROM:<> rejection from other early rejections (e.g.
2066 rejection of HELO). When verifying a recipient using a non-null MAIL
2067 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2068 Whatever the result of the callout, the value of the domain cache is
2069 left unchanged (for any other kind of callout, getting as far as trying
2070 RCPT means that the domain itself is ok).

2104PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2106 probably the interface on which it is arriving) and not to the outgoing
2107 callout (which could be using a different interface). This has been
2108 changed to use the value of the helo_data option from the smtp transport
2109 instead - this is what is used when a message is actually being sent. If
2110 there is no remote transport (possible with a router that sets up host
2111 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2115 (a) The code assumed that strncpy() returns a negative number on buffer
2116 overflow, which isn't the case. Replaced with Exim's string_format()
2117 function.
2118 (b) There were several signed/unsigned issues. I just did the minimum
2119 hacking in of casts. There is scope for a larger refactoring.
2120 (c) The code used strcasecmp() which is not a standard C function.
2121 Replaced with Exim's strcmpic() function.
2122 (d) The code set only $1; it now sets $auth1 as well.
2123 (e) A simple test gave the error "authentication client didn't specify
2124 service in request". It would seem that Dovecot has changed its
2125 interface. Fortunately there's a specification; I followed it and
2126 changed what the client sends and it appears to be working now.

2132 address A is aliased to B and C, where B exists and C does not. Without
2133 -v the output is "A verified" because verification stops after a
2134 successful redirection if more than one address is generated. However,
2135 with -v the child addresses are also verified. Exim was outputting "A
2136 failed to verify" and then showing the successful verification for C,
2137 with its parentage. It now outputs "B failed to verify", showing B's
2138 parentage before showing the successful verification of C.

322050c2
PH
2144PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2145 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2146 they consult the DNS. I had assumed they would set it the way they
2147 wanted; and indeed my experiments on Linux seem to show that in some
2148 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2149 To be on the safe side, however, I have now made the interface to
2150 host_find_byname() similar to host_find_bydns(), with an argument
2151 containing the DNS resolver options. The host_find_byname() function now
2152 sets these options at its start, just as host_find_bydns() does. The smtp
2153 transport options dns_qualify_single and dns_search_parents are passed to
2154 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2155 of host_find_byname() use the default settings of RES_DEFNAMES
2156 (qualify_single) but not RES_DNSRCH (search_parents).

2159 spool_read_header() do less string testing, by means of a preliminary
2160 switch on the second character of optional "-foo" lines. (This is
2161 overdue, caused by the large number of possibilities that now exist.
2162 Originally there were few.) While I was there, I also converted the
2163 str(n)cmp tests so they don't re-test the leading "-" and the first
2164 character, in the hope this might squeeze out yet more improvement.

2166PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2167 flag allowing group syntax was set by the header_syntax check but not
2168 turned off, possible causing trouble later; (2) The flag was not being
2169 set at all for the header_verify test, causing "group"-style headers to
2170 be rejected. I have now set it in this case, and also caused header_
2171 verify to ignore an empty address taken from a group. While doing this, I
2172 came across some other cases where the code for allowing group syntax
2173 while scanning a header line wasn't quite right (mostly, not resetting
2174 the flag correctly in the right place). These bugs could have caused
2175 trouble for malformed header lines. I hope it is now all correct.

PH
2177PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2178 with the "reply" argument non-NULL. The code, however (which originally
2179 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2180 but it didn't always do it. This confused somebody who was copying the
2181 code for some other use. I have removed all the tests.

PH
2183PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2184 feature that was used to support insecure browsers during the U.S. crypto
2185 embargo. It requires special client support, and Exim is probably the
2186 only MTA that supported it -- and would never use it because real RSA is
2187 always available. This code has been removed, because it had the bad
2188 effect of slowing Exim down by computing (never used) parameters for the
2189 RSA_EXPORT functionality.

2194 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2195 if the connection is using TLS or if the remote IP is the same as the
2196 local IP, and the "valid-client-cert option" if a client certificate has
2197 been verified.

2228
2229PH/30 Exim was sometimes attempting to deliver messages that had suffered
2230 address errors (4xx response to RCPT) over the same connection as other
2231 messages routed to the same hosts. Such deliveries are always "forced",
2232 so retry times are not inspected. This resulted in far too many retries
2233 for the affected addresses. The effect occurred only when there were more
2234 hosts than the hosts_max_try setting in the smtp transport when it had
2235 the 4xx errors. Those hosts that it had tried were not added to the list
2236 of hosts for which the message was waiting, so if all were tried, there
2237 was no problem. Two fixes have been applied:
2238
2239 (i) If there are any address or message errors in an SMTP delivery, none
2240 of the hosts (tried or untried) are now added to the list of hosts
2241 for which the message is waiting, so the message should not be a
2242 candidate for sending over the same connection that was used for a
2243 successful delivery of some other message. This seems entirely
2244 reasonable: after all the message is NOT "waiting for some host".
2245 This is so "obvious" that I'm not sure why it wasn't done
2246 previously. Hope I haven't missed anything, but it can't do any
2247 harm, as the worst effect is to miss an optimization.
2248
2249 (ii) If, despite (i), such a delivery is accidentally attempted, the
2250 routing retry time is respected, so at least it doesn't keep
2251 hammering the server.

2266PH/35 The error "getsockname() failed: connection reset by peer" was being
2267 written to the panic log as well as the main log, but it isn't really

2269 removed the panic log writing for the ECONNRESET error when getsockname()
2270 fails.
2271
48c7f9e2
PH
2272PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2273 runs only) independently of the message's sender address. This meant
2274 that, if the 4xx error was in fact related to the sender, a different
2275 message to the same recipient with a different sender could confuse
2276 things. In particualar, this can happen when sending to a greylisting
2277 server, but other circumstances could also provoke similar problems.
2278 I have changed the default so that the retry time for these errors is now
2279 based a combination of the sender and recipient addresses. This change
2280 can be overridden by setting address_retry_include_sender=false in the
2281 smtp transport.

2549PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2551 Unfortunately, if there is a major crisis, such as a disk failure,
2552 tcp-wrappers gives "deny", whereas what one would like would be some
2553 kind of temporary error. A kludge has been added to help with this.
2554 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2555 554 error is used if errno is still zero or contains ENOENT (which occurs
2556 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2557 451 error is used.

2595 systems, as well as to others that have similar system calls. The broken
2596 code found IPv4 interfaces correctly, but gave incorrect values for the
2597 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2598 that it would not match correctly against @[] and not recognize the IPv6
2599 addresses as local.

2642 autoreply, Exim could try to deliver to a non-existent relative file
2643 name, causing unrelated and misleading errors. What now happens is that

2662 non-existent - all you got was a failure to exec. I have made two
2663 changes:
2664
2665 (a) Failures to set uid/gid, the current directory, or a process leader
2666 in a subprocess such as that created by queryprogram now generate
2667 suitable debugging ouput when -d is set.
2668
2669 (b) The queryprogram router detects when it is not running as root,
2670 outputs suitable debugging information if -d is set, and then runs
2671 the subprocess without attempting to change uid/gid.

2677 additional section of a DNS packet that returns MX or SRV records.
2678 Instead, it always explicitly searches for A/AAAA records. This avoids
2679 major problems that occur when a DNS server includes only records of one
2680 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2681 fixed another bug: if SRV records were looked up and the corresponding
2682 address records were *not* found in the additional section, the port
2683 values from the SRV records were lost.

2685PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2692
727071f8
PH
2693PH/19 When calculating a retry time, Exim used to measure the "time since
2694 failure" by looking at the "first failed" field in the retry record. Now
2695 it does not use this if it is later than than the arrival time of the
2696 message. Instead it uses the arrival time. This makes for better
2697 behaviour in cases where some deliveries succeed, thus re-setting the
2698 "first failed" field. An example is a quota failure for a huge message
2699 when small messages continue to be delivered. Without this change, the
2700 "time since failure" will always be short, possible causing more frequent
2701 delivery attempts for the huge message than are intended.

PH
2798PH/42 The content-scanning code uses fopen() to create files in which to put
2799 message data. Previously it was not paying any attention to the mode of
2800 the files. Exim runs with umask(0) because the rest of the code creates
2801 files with open(), and sets the required mode explicitly. Thus, these
2802 files were ending up world-writeable. This was not a big issue, because,
2803 being within the spool directory, they were not world-accessible. I have
2804 created a function called modefopen, which takes an additional mode
2805 argument. It sets umask(777), creates the file, chmods it to the required
2806 mode, then resets the umask. All the relevant calls to fopen() in the
2807 content scanning code have been changed to use this function.

2844
2845 (i) Exim was not creating retry information for temporary errors given
2846 for individual recipients after the DATA command when the smtp transport
2847 was used in LMTP mode. This meant that they could be retried too
2848 frequently, and not timed out correctly.
2849
2850 (ii) Exim was setting the flag that allows error details to be returned
2851 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2852 recipients that were returned after the DATA command.
2853
2854PH/53 This is related to PH/52, but is more general: for any failing address,
2855 when detailed error information was permitted to be returned to the
2856 sender, but the error was temporary, then after the final timeout, only
2857 "retry timeout exceeded" was returned. Now it returns the full error as

2928PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2929 function verify_get_ident() calls ip_connect() to connect a socket, but
2930 if the "connect()" function timed out, ip_connect() used to close the
2931 socket. However, verify_get_ident() also closes the socket later, and in
2932 between Exim writes to the log, which may get opened at this point. When
2933 the socket was closed in ip_connect(), the log could get the same file
2934 descriptor number as the socket. This naturally causes chaos. The fix is
2935 not to close the socket in ip_connect(); the socket should be closed by
2936 the function that creates it. There was only one place in the code where
2937 this was missing, in the iplookup router, which I don't think anybody now
2938 uses, but I've fixed it anyway.

2965 (3) Reset the variables that are obtained from the first argument of
2966 ${prvscheck and used in the second argument before leaving the code,
2967 because their memory is reclaimed, so using them afterwards may do
2968 silly things.

2995 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2996 not being looked up in the rDNS to get a host name, Exim was showing the
2997 IP address twice in Received: lines, even though the IP addresses were
2998 identical. For example:
2999
3000 Received: from [1.2.3.4] (helo=[1.2.3.4])
3001
3002 However, if the real host name was known, it was omitting the HELO data

3004 doesn't show the same IP address twice.

3096 addresses acquired from the DNS when checking that the found name did
3097 have the original IP as one of its addresses. Since any found IPv6
3098 addresses are likely to be in abbreviated form, the comparison could
3099 fail. Luckily, there already exists a function for doing the comparison
3100 by converting both addresses to binary, so now that is used instead of

3127TF/01 The control=submission/name=... option had a problem with syntax
3128 errors if the name included a slash character. The /name= option
3129 now slurps the rest of the string, so it can include any characters
3130 but it must come last in the list of options (after /sender_retain
3131 or /domain=).

3148PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
3149 fread() to skip over the body file's header line, because in Cygwin the
3150 header line is locked and is inaccessible.

PH
3152PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
3153 co-exist for some time) to make it clear that it is the Exim ID that is
3154 referenced, not the Message-ID: header line.

3180PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3181 run a filter in a subprocess. This could lead to confusion in subsequent
3182 lookups in the parent process. There should also be a search_tidyup() at
3183 the end of the subprocess.

PH
3185PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3186 only if the host matched helo_try_verify_hosts, which caused the
3187 verification to occur when the EHLO/HELO command was issued. The ACL just
3188 tested the remembered result. Now, if a previous verification attempt has
3189 not happened, "verify = helo" does it there and then.

3208PH/20 If a delivery was routed to a non-standard port by means of an SRV

3213 fallback_hosts, and "hosts" in the smtp transport.

PH
3218PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3219 authentication with radiusclient 0.4.9:
3220
3221 - Error returned from rc_read_config was caught wrongly
3222 - Username/password not passed on to radius server due to wrong length.
3223
3224 The presumption is that some radiusclient API changes for 4.51/PH/17
3225 were not taken care of correctly. The code is still untested by me (my
3226 Linux distribution still has 0.3.2 of radiusclient), but it was
3227 contributed by a Radius user.

PH
3242PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
3243 commands, but it was not correctly comparing the address with the actual
3244 client host address. Thus, it would show the EHLO address in Received:
3245 header lines when this was not necessary.

PH
3249PH/28 Exim tries to create and chdir to its spool directory when it starts;
3250 it should be ignoring failures (because with -C, for example, it has lost

3270PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
3271 Local/Makefile (with some defaults set). These are used in built scripts
3272 such as exicyclog, but they have never been used in the exim_install
3273 script (though there are many overriding facilities there). I have
3274 arranged that the exim_install script now takes note of these two
3275 settings.

3279PH/36 When a locally submitted message by a trusted user did not contain a
3280 From: header, and the sender address was obtained from -f or from an SMTP
3281 MAIL command, and the trusted user did not use -F to supply a sender
3282 name, $originator_name was incorrectly used when constructing a From:
3283 header. Furthermore, $originator_name was used for submission mode
3284 messages from external hosts without From: headers in a similar way,
3285 which is clearly wrong.

3289PH/38 When log_selector = +received_sender was set, and the addition of the
