7JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
8 and 3.4.4 - once the server is enabled to respond to an OCSP request
9 it does even when not requested, resulting in a stapling non-aware
10 client dropping the TLS connection.

TF
12TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
13 support variable-length bit vectors. No functional change.
14

TF
15TF/02 Improve the consistency of logging incoming and outgoing interfaces.
16 The I= interface field on outgoing lines is now after the H= remote
17 host field, same as incoming lines. There is a separate
18 outgoing_interface log selector which allows you to disable the
19 outgoing I= field.

JH
21JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
22 If not running log_selector +smtp_connection the mainlog would be held
23 open indefinitely after a "too many connections" event, including to a
24 deleted file after a log rotate. Leave the per net connection logging
25 leaving it open for efficiency as that will be quickly detected by the
26 check on the next write.

28HS/01 Bug 1671: Fix post transport crash.
29 Processing the wait-<transport> messages could crash the delivery
30 process if the message IDs didn't exist for some reason. When
31 using 'split_spool_directory=yes' the construction of the spool
32 file name failed already, exposing the same netto behaviour.

37JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
38 to DSN fail messages (bounces): remote IP, remote greeting, remote response
39 to HELO, local diagnostic string.
40
805bb5c3
JH
41JH/05 Downgrade message for a TLS-certificate-based authentication fail from
42 log line to debug. Even when configured with a tls authenticator many
43 client connections are expected to not authenticate in this way, so
44 an authenticate fail is not an error.

46HS/02 Add the Exim version string to the process info. This way exiwhat
47 gives some more detail about the running daemon.

JH
49JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
50 matter for fast-change records such as DNSBLs.
51
6f6dedcc
JH
52JH/07 Bug 1678: Always record an interface option value, if set, as part of a
53 retry record, even if constant. There may be multiple transports with
54 different interface settings and the retry behaviour needs to be kept
55 distinct.

JH
71JH/14 Change header file name for freeradius-client. Relevant if compiling
72 with Radius support; from the Gentoo tree and checked under Fedora.

75
6ff55e50
JH
76JH/16 Bug 1714: Permit an empty string as expansion result for transport
77 option transport_filter, meaning no filtering.

79JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
80
23f3dc67
JH
81JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
82 defaults to "*" (all hosts). The variable is now available when not built
83 with TLS, default unset, mainly to enable keeping the testuite sane.
84 If a server certificate is not supplied (via tls_certificate) an error is
85 logged, and clients will find TLS connections fail on startup. Presumably
86 they will retry in-clear.
87 Packagers of Exim are strongly encouraged to create a server certificate
88 at installation time.
89
240c288f
JH
90HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
91 with the $config_file variable.
92
5ef5dd52
JB
93JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
94 in transport context, after the attempt, and per-recipient. The latter type
95 is per host attempted. The event data is the error message, and the errno
96 information encodes the lookup type (A vs. MX) used for the (first) host,
97 and the trailing two digits of the smtp 4xx reponse.

108 it.
109
01a4a5c5 110JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 111 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
112 can be used to disable this per-host. The build option
113 EXPERIMENTAL_CERTNAMES is withdrawn.

JH
127JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
128 Status Notification (bounce) messages are now MIME format per RFC 3464.
129 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
130 under the control of the dsn_advertise_hosts option, and routers may
131 have a dsn_lasthop option.

fd4d8871
R
153 modifiers per server. Patch originally by <rommer@active.by>.
154
155JH/16 The spamd_address main option now supports a mixed list of local

195 Normally benign, it bites when the pair was led to by a CNAME;
196 modern usage is to not canoicalize the domain to a CNAME target
197 (and we were inconsistent anyway for A-only vs AAAA+A).

220Exim version 4.85
221-----------------
222TL/01 When running the test suite, the README says that variables such as
223 no_msglog_check are global and can be placed anywhere in a specific
224 test's script, however it was observed that placement needed to be near
225 the beginning for it to behave that way. Changed the runtest perl
226 script to read through the entire script once to detect and set these
227 variables, reset to the beginning of the script, and then run through
228 the script parsing/test process like normal.

238TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
239 syntax errors in an expansion can be treated as a string instead of

WB
255JH/05 Fix results-pipe from transport process. Several recipients, combined
256 with certificate use, exposed issues where response data items split
257 over buffer boundaries were not parsed properly. This eventually
258 resulted in duplicates being sent. This issue only became common enough
259 to notice due to the introduction of conection certificate information,
260 the item size being so much larger. Found and fixed by Wolfgang Breyha.

270 is EXPERIMENTAL_EVENT, the main-configuration and transport options

aec45841 272 and $event_defer_errno. There is a new variable $verify_mode, usable in

273 routers, transports and related events. The tls:cert event is now also

332TF/01 Correctly close the server side of TLS when forking for delivery.
333
334 When a message was received over SMTP with TLS, Exim failed to clear up
335 the incoming connection properly after forking off the child process to
336 deliver the message. In some situations the subsequent outgoing
337 delivery connection happened to have the same fd number as the incoming
338 connection previously had. Exim would try to use TLS and fail, logging

585TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
586
587 When a queue runner is handling a message, Exim first routes the
588 recipient addresses, during which it prunes them based on the retry
589 hints database. After that it attempts to deliver the message to
590 any remaining recipients. It then updates the hints database using
591 the retry rules.
592
593 So if a recipient address works intermittently, it can get repeatedly
594 deferred at routing time. The retry hints record remains fresh so the
595 address never reaches the final cutoff time.
596
597 This is a fairly common occurrence when a user is bumping up against
598 their storage quota. Exim had some logic in its local delivery code
599 to deal with this. However it did not apply to per-recipient defers
600 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
601
1ddeb334
TF
602 This change adds a proper retry rule check during routing so that the
603 final cutoff time is checked against the message's age. We only do
604 this check if there is an address retry record and there is not a
605 domain retry record; this implies that previous attempts to handle
606 the address had the retry_use_local_parts option turned on. We use
607 this as an approximation for the destination being like a local
608 delivery, as in LMTP.
67bd1ab3
TF
609
610 I suspect this new check makes the old local delivery cutoff check
611 redundant, but I have not verified this so I left the code in place.

619 When I ran the test suite under the user fanf2, Exim expanded
620 the header to contain my full name, whereas it should have added
621 a Resent-Sender: header. It erroneously treats any prefix of the
622 username as equal to the username.

646 Server implementation by Todd Lyons, client by JH.
647 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
648 config variable "prdr_enable" controls whether the server
649 advertises the facility. If the client requests PRDR a new
650 acl_data_smtp_prdr ACL is called once for each recipient, after
651 the body content is received and before the acl_smtp_data ACL.
652 The client is controlled by bolth of: a hosts_try_prdr option
653 on the smtp transport, and the server advertisement.
654 Default client logging of deliveries and rejections involving
655 PRDR are flagged with the string "PRDR".

933TF/03 Make the exiwhat support code safe for signals. Previously Exim might
934 lock up or crash if it happened to be inside a call to libc when it
935 got a SIGUSR1 from exiwhat.
936
937 The SIGUSR1 handler appends the current process status to the process
938 log which is later printed by exiwhat. It used to use the general
939 purpose logging code to do this, but several functions it calls are
940 not safe for signals.
941
942 The new output code in the SIGUSR1 handler is specific to the process
943 log, and simple enough that it's easy to inspect for signal safety.
944 Removing some special cases also simplifies the general logging code.
945 Removing the spurious timestamps from the process log simplifies
946 exiwhat.
947
c99ce5c9
TF
948TF/04 Improved ratelimit ACL condition.
949
950 The /noupdate option has been deprecated in favour of /readonly which
951 has clearer semantics. The /leaky, /strict, and /readonly update modes
952 are mutually exclusive. The update mode is no longer included in the
953 database key; it just determines when the database is updated. (This
954 means that when you upgrde Exim will forget old rate measurements.)
955
956 Exim now checks that the per_* options are used with an update mode that
957 makes sense for the current ACL. For example, when Exim is processing a
958 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
959 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
960 must specify per_mail/readonly. If you omit the update mode it defaults to
961 /leaky where that makes sense (as before) or /readonly where required.
962
963 The /noupdate option is now undocumented but still supported for
964 backwards compatibility. It is equivalent to /readonly except that in
965 ACLs where /readonly is required you may specify /leaky/noupdate or
966 /strict/noupdate which are treated the same as /readonly.
967
968 A useful new feature is the /count= option. This is a generalization
969 of the per_byte option, so that you can measure the throughput of other
970 aggregate values. For example, the per_byte option is now equivalent
971 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
972
973 The per_rcpt option has been generalized using the /count= mechanism
974 (though it's more complicated than the per_byte equivalence). When it is
975 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
976 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
977 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
978 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
979 Note that using per_rcpt with a non-readonly update mode in more than
980 one ACL will cause the recipients to be double-counted. (The per_mail
981 and per_byte options don't have this problem.)
982
983 The handling of very low rates has changed slightly. If the computed rate
984 is less than the event's count (usually one) then this event is the first
985 after a long gap. In this case the rate is set to the same as this event's
986 count, so that the first message of a spam run is counted properly.
987
988 The major new feature is a mechanism for counting the rate of unique
989 events. The new per_addr option counts the number of different
990 recipients that someone has sent messages to in the last time period. It
991 behaves like per_rcpt if all the recipient addresses are different, but
992 duplicate recipient addresses do not increase the measured rate. Like
993 the /count= option this is a general mechanism, so the per_addr option
994 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
995 example, measure the rate that a client uses different sender addresses
996 with the options per_mail/unique=$sender_address. There are further
997 details in the main documentation.

1207PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
1208 If dropping privileges for untrusted macros, we disabled normal logging
1209 on the basis that it would fail; for the Exim run-time user, this is not
1210 the case, and it resulted in successful deliveries going unlogged.
1211 Fixed. Reported by Andreas Metzler.

PH
1571PH/02 When an IPv6 address is converted to a string for single-key lookup
1572 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1573 dots are used instead of colons so that keys in lsearch files need not
1574 contain colons. This was done some time before quoting was made available
1575 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1576 (notated using the quote facility) so as to distinguish them from IPv4
1577 keys. This meant that lookups for IP addresses in host lists did not work
1578 for iplsearch lookups.
1579
1580 This has been fixed by arranging for IPv6 addresses to be expressed with
1581 colons if the lookup type is iplsearch. This is not incompatible, because
1582 previously such lookups could never work.
1583
1584 The situation is now rather anomolous, since one *can* have colons in
1585 ordinary lsearch keys. However, making the change in all cases is
1586 incompatible and would probably break a number of configurations.

1591MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1592 conversion specification without a maximum field width, thereby enabling
1593 a rogue spamd server to cause a buffer overflow. While nobody in their
1594 right mind would setup Exim to query an untrusted spamd server, an
1595 attacker that gains access to a server running spamd could potentially
1596 exploit this vulnerability to run arbitrary code as the Exim user.

1601MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1602 a directory entry by the name of the lookup key. Previously, if a
1603 symlink pointed to a non-existing file or a file in a directory that
1604 Exim lacked permissions to read, a lookup for a key matching that

1789PH/29 SMTP synchronization checks are implemented when a command is read -
1790 there is a check that no more input is waiting when there shouldn't be

1792 some time before the response is written. In this time, more input might
1793 arrive, invalidly. So now there are extra checks after an ACL has run for
1794 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1795 pipelining has not been advertised.

1810 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1811 was a macro that became an assignment, so it seemed to work. This has

PH
1869 the response to the final '.' that terminates a message, but only in the
1870 case where the client has not sent further data following the '.'
1871 (unfortunately, this is allowed). However, in many cases there won't be
1872 any further data because there won't be any more messages to send. A call
1873 to select() can be used: if it shows that the input is "ready", there is
1874 either input waiting, or the socket has been closed. An attempt to read
1875 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1876 would have sent an OK response which the client would never have see.

1887PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1888 fixed by 4.65/MH/01 (is this a record?) are fixed:
1889
1890 (i) An empty string was always treated as zero by the numeric comparison
1891 operators. This behaviour has been restored.
1892
1893 (ii) It is documented that the numeric comparison operators always treat
1894 their arguments as decimal numbers. This was broken in that numbers
1895 starting with 0 were being interpreted as octal.
1896
1897 While fixing these problems I realized that there was another issue that
1898 hadn't been noticed. Values of message_size_limit (both the global option
1899 and the transport option) were treated as octal if they started with 0.
1900 The documentation was vague. These values are now always treated as
1901 decimal, and I will make that clear in the documentation.

PH
1945PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1946 callout verification, Exim cached a "reject" for the entire domain. This
1947 is correct for most verifications, but it is not correct for a recipient
1948 verification with use_sender or use_postmaster set, because in that case
1949 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1950 case of MAIL FROM:<> rejection from other early rejections (e.g.
1951 rejection of HELO). When verifying a recipient using a non-null MAIL
1952 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1953 Whatever the result of the callout, the value of the domain cache is
1954 left unchanged (for any other kind of callout, getting as far as trying
1955 RCPT means that the domain itself is ok).

1989PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1990 hostname. This is wrong, because it relates to the incoming message (and
1991 probably the interface on which it is arriving) and not to the outgoing
1992 callout (which could be using a different interface). This has been
1993 changed to use the value of the helo_data option from the smtp transport
1994 instead - this is what is used when a message is actually being sent. If
1995 there is no remote transport (possible with a router that sets up host
1996 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2000 (a) The code assumed that strncpy() returns a negative number on buffer
2001 overflow, which isn't the case. Replaced with Exim's string_format()
2002 function.
2003 (b) There were several signed/unsigned issues. I just did the minimum
2004 hacking in of casts. There is scope for a larger refactoring.
2005 (c) The code used strcasecmp() which is not a standard C function.
2006 Replaced with Exim's strcmpic() function.
2007 (d) The code set only $1; it now sets $auth1 as well.
2008 (e) A simple test gave the error "authentication client didn't specify
2009 service in request". It would seem that Dovecot has changed its
2010 interface. Fortunately there's a specification; I followed it and
2011 changed what the client sends and it appears to be working now.

2017 address A is aliased to B and C, where B exists and C does not. Without
2018 -v the output is "A verified" because verification stops after a
2019 successful redirection if more than one address is generated. However,
2020 with -v the child addresses are also verified. Exim was outputting "A
2021 failed to verify" and then showing the successful verification for C,
2022 with its parentage. It now outputs "B failed to verify", showing B's
2023 parentage before showing the successful verification of C.

PH
2029PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2030 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2031 they consult the DNS. I had assumed they would set it the way they
2032 wanted; and indeed my experiments on Linux seem to show that in some
2033 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2034 To be on the safe side, however, I have now made the interface to
2035 host_find_byname() similar to host_find_bydns(), with an argument
2036 containing the DNS resolver options. The host_find_byname() function now
2037 sets these options at its start, just as host_find_bydns() does. The smtp
2038 transport options dns_qualify_single and dns_search_parents are passed to
2039 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2040 of host_find_byname() use the default settings of RES_DEFNAMES
2041 (qualify_single) but not RES_DNSRCH (search_parents).

2043PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2044 spool_read_header() do less string testing, by means of a preliminary
2045 switch on the second character of optional "-foo" lines. (This is
2046 overdue, caused by the large number of possibilities that now exist.
2047 Originally there were few.) While I was there, I also converted the
2048 str(n)cmp tests so they don't re-test the leading "-" and the first
2049 character, in the hope this might squeeze out yet more improvement.

PH
2051PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2052 flag allowing group syntax was set by the header_syntax check but not
2053 turned off, possible causing trouble later; (2) The flag was not being
2054 set at all for the header_verify test, causing "group"-style headers to
2055 be rejected. I have now set it in this case, and also caused header_
2056 verify to ignore an empty address taken from a group. While doing this, I
2057 came across some other cases where the code for allowing group syntax
2058 while scanning a header line wasn't quite right (mostly, not resetting
2059 the flag correctly in the right place). These bugs could have caused
2060 trouble for malformed header lines. I hope it is now all correct.

PH
2062PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2064 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2065 but it didn't always do it. This confused somebody who was copying the
2066 code for some other use. I have removed all the tests.

PH
2068PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2069 feature that was used to support insecure browsers during the U.S. crypto
2070 embargo. It requires special client support, and Exim is probably the
2071 only MTA that supported it -- and would never use it because real RSA is
2072 always available. This code has been removed, because it had the bad
2073 effect of slowing Exim down by computing (never used) parameters for the
2074 RSA_EXPORT functionality.

PH
2076PH/21 On the advice of Timo Sirainen, added a check to the dovecot

2079 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2080 if the connection is using TLS or if the remote IP is the same as the
2081 local IP, and the "valid-client-cert option" if a client certificate has
2082 been verified.

2113
2114PH/30 Exim was sometimes attempting to deliver messages that had suffered
2115 address errors (4xx response to RCPT) over the same connection as other
2116 messages routed to the same hosts. Such deliveries are always "forced",
2117 so retry times are not inspected. This resulted in far too many retries
2118 for the affected addresses. The effect occurred only when there were more
2119 hosts than the hosts_max_try setting in the smtp transport when it had
2120 the 4xx errors. Those hosts that it had tried were not added to the list
2121 of hosts for which the message was waiting, so if all were tried, there
2122 was no problem. Two fixes have been applied:
2123
2124 (i) If there are any address or message errors in an SMTP delivery, none
2125 of the hosts (tried or untried) are now added to the list of hosts
2126 for which the message is waiting, so the message should not be a
2127 candidate for sending over the same connection that was used for a
2128 successful delivery of some other message. This seems entirely
2129 reasonable: after all the message is NOT "waiting for some host".
2130 This is so "obvious" that I'm not sure why it wasn't done
2131 previously. Hope I haven't missed anything, but it can't do any
2132 harm, as the worst effect is to miss an optimization.
2133
2134 (ii) If, despite (i), such a delivery is accidentally attempted, the
2135 routing retry time is respected, so at least it doesn't keep
2136 hammering the server.

2151PH/35 The error "getsockname() failed: connection reset by peer" was being
2152 written to the panic log as well as the main log, but it isn't really

2154 removed the panic log writing for the ECONNRESET error when getsockname()
2155 fails.
2156
48c7f9e2
PH
2157PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2158 runs only) independently of the message's sender address. This meant
2159 that, if the 4xx error was in fact related to the sender, a different
2160 message to the same recipient with a different sender could confuse
2161 things. In particualar, this can happen when sending to a greylisting
2162 server, but other circumstances could also provoke similar problems.
2163 I have changed the default so that the retry time for these errors is now
2164 based a combination of the sender and recipient addresses. This change
2165 can be overridden by setting address_retry_include_sender=false in the
2166 smtp transport.

2434PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2436 Unfortunately, if there is a major crisis, such as a disk failure,
2437 tcp-wrappers gives "deny", whereas what one would like would be some
2438 kind of temporary error. A kludge has been added to help with this.
2439 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2440 554 error is used if errno is still zero or contains ENOENT (which occurs
2441 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2442 451 error is used.

2478PH/01 The code for finding all the local interface addresses on a FreeBSD
2479 system running IPv6 was broken. This may well have applied to all BSD
2480 systems, as well as to others that have similar system calls. The broken
2481 code found IPv4 interfaces correctly, but gave incorrect values for the
2482 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2483 that it would not match correctly against @[] and not recognize the IPv6
2484 addresses as local.

2527 autoreply, Exim could try to deliver to a non-existent relative file

2551 in a subprocess such as that created by queryprogram now generate
2552 suitable debugging ouput when -d is set.

2562 additional section of a DNS packet that returns MX or SRV records.
2563 Instead, it always explicitly searches for A/AAAA records. This avoids
2564 major problems that occur when a DNS server includes only records of one
2565 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2566 fixed another bug: if SRV records were looked up and the corresponding
2567 address records were *not* found in the additional section, the port
2568 values from the SRV records were lost.

2570PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2578PH/19 When calculating a retry time, Exim used to measure the "time since
2579 failure" by looking at the "first failed" field in the retry record. Now
2580 it does not use this if it is later than than the arrival time of the
2581 message. Instead it uses the arrival time. This makes for better
2582 behaviour in cases where some deliveries succeed, thus re-setting the
2583 "first failed" field. An example is a quota failure for a huge message
2584 when small messages continue to be delivered. Without this change, the
2585 "time since failure" will always be short, possible causing more frequent
2586 delivery attempts for the huge message than are intended.

2683PH/42 The content-scanning code uses fopen() to create files in which to put

2686 files with open(), and sets the required mode explicitly. Thus, these
2687 files were ending up world-writeable. This was not a big issue, because,
2688 being within the spool directory, they were not world-accessible. I have
2689 created a function called modefopen, which takes an additional mode
2690 argument. It sets umask(777), creates the file, chmods it to the required
2691 mode, then resets the umask. All the relevant calls to fopen() in the

2727PH/52 Two bugs concerned with error handling when the smtp transport is
2728 used in LMTP mode:
2729
2730 (i) Exim was not creating retry information for temporary errors given
2731 for individual recipients after the DATA command when the smtp transport
2732 was used in LMTP mode. This meant that they could be retried too
2733 frequently, and not timed out correctly.
2734
2735 (ii) Exim was setting the flag that allows error details to be returned
2736 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2737 recipients that were returned after the DATA command.
2738
2739PH/53 This is related to PH/52, but is more general: for any failing address,
2740 when detailed error information was permitted to be returned to the
2741 sender, but the error was temporary, then after the final timeout, only
2742 "retry timeout exceeded" was returned. Now it returns the full error as
2743 well as "retry timeout exceeded".

2799PH/68 The bounce_return_message and bounce_return_body options were not being
2800 honoured for bounces generated during the reception of non-SMTP messages.
2801 In particular, this applied to messages rejected by the ACL. This bug has
2802 been fixed. However, if bounce_return_message is true and bounce_return_
2803 body is false, the headers that are returned for a non-SMTP message
2804 include only those that have been read before the error was detected.

2807PH/69 The HTML version of the specification is now built in a directory called

PH
2813PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2814 function verify_get_ident() calls ip_connect() to connect a socket, but
2815 if the "connect()" function timed out, ip_connect() used to close the
2816 socket. However, verify_get_ident() also closes the socket later, and in
2817 between Exim writes to the log, which may get opened at this point. When
2818 the socket was closed in ip_connect(), the log could get the same file
2819 descriptor number as the socket. This naturally causes chaos. The fix is
2820 not to close the socket in ip_connect(); the socket should be closed by
2821 the function that creates it. There was only one place in the code where
2822 this was missing, in the iplookup router, which I don't think anybody now
2823 uses, but I've fixed it anyway.

2842PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2843
2844 (1) Generate an error if the third argument for the ${prvs expansion is
2845 not a single digit.
2846
2847 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2848 string.
2849
2850 (3) Reset the variables that are obtained from the first argument of
2851 ${prvscheck and used in the second argument before leaving the code,
2852 because their memory is reclaimed, so using them afterwards may do
2853 silly things.
2854
2855 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2856 one (it's much easier than Tom thought :-).
2857
2858 (5) Because of (4), we can now allow for the use of $prvscheck_result
2859 inside the third argument.

2868PH/05 When a filter generated an autoreply, the entire To: header line was
2869 quoted in the delivery log line, like this:
2870
2871 => >A.N.Other <ano@some.domain> <original@ddress> ...
2872
2873 This has been changed so that it extracts the operative address. There
2874 may be more than one such address. If so, they are comma-separated, like
2875 this:
2876
2877 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2879PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2880 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2881 not being looked up in the rDNS to get a host name, Exim was showing the
2882 IP address twice in Received: lines, even though the IP addresses were
2883 identical. For example:
2884
2885 Received: from [1.2.3.4] (helo=[1.2.3.4])
2886
2887 However, if the real host name was known, it was omitting the HELO data
2888 if it matched the actual IP address. This has been tidied up so that it
2889 doesn't show the same IP address twice.

PH
2891PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2915PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2916 Electronic Mail") by including:
2917
2918 Auto-submitted: auto-generated
2919
2920 in the messages that it generates (bounce messages and others, such as
2921 warnings). In the case of bounce messages for non-SMTP mesages, there was
2922 also a typo: it was using "Auto_submitted" (underscore instead of
2923 hyphen). Since every message generated by Exim is necessarily in response
2924 to another message, thes have all been changed to:
2925
2926 Auto-Submitted: auto-replied
2927
2928 in accordance with these statements in the RFC:
2929
2930 The auto-replied keyword:
2931
2932 - SHOULD be used on messages sent in direct response to another
2933 message by an automatic process,
2934
2935 - MUST NOT be used on manually-generated messages,
2936
2937 - MAY be used on Delivery Status Notifications (DSNs) and Message
2938 Disposition Notifications (MDNs),
2939
2940 - MUST NOT be used on messages generated by automatic or periodic
2941 processes, except for messages which are automatic responses to
2942 other messages.

PH
2978PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2979 canonical form (as documented). However, after a host name lookup from
2980 the IP address, check_host() was doing a simple string comparison with
2981 addresses acquired from the DNS when checking that the found name did
2982 have the original IP as one of its addresses. Since any found IPv6
2983 addresses are likely to be in abbreviated form, the comparison could
2984 fail. Luckily, there already exists a function for doing the comparison
2985 by converting both addresses to binary, so now that is used instead of
2986 the text comparison.
2987
96776534
PH
2988PH/20 There was another similar case to PH/19, when a complete host name was

3143 because an input line was too long, either on its own, or by virtue of

3153PH/33 Added "verify = not_blind".
3154
3155PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
3156 Local/Makefile (with some defaults set). These are used in built scripts
3157 such as exicyclog, but they have never been used in the exim_install
3158 script (though there are many overriding facilities there). I have
3159 arranged that the exim_install script now takes note of these two
3160 settings.

3164PH/36 When a locally submitted message by a trusted user did not contain a
3165 From: header, and the sender address was obtained from -f or from an SMTP
3166 MAIL command, and the trusted user did not use -F to supply a sender
3167 name, $originator_name was incorrectly used when constructing a From:
3168 header. Furthermore, $originator_name was used for submission mode
3169 messages from external hosts without From: headers in a similar way,
3170 which is clearly wrong.

3174PH/38 When log_selector = +received_sender was set, and the addition of the
3175 sender made the log line's construction buffer exactly full, or one byte

3177 subsequently added.

3203PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
3204 avoiding the need to install special zones in a real server. This is
3205 backwards compatible; if it can't find the fake resolver, it drops back.
3206 Thus, both old and new test suites can be run.

3236TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
3237 if the DNS of the sending site is misconfigured. This is quite a

3250PH/01 When a transport filter timed out in a pipe delivery, and the pipe

3260PH/03 The warning log line about a condition test deferring for a "warn" verb
3261 was being output only once per connection, rather than after each

3263 "warn" verbs). This seems wrong, so I have changed it.

3265TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3266 it should not have, which might have caused a crash in the right

3269PH/04 Installed a modified version of Tony Finch's patch to make submission

PH
3283PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3284 with the definition in sysexits.h (which is #included earlier).
3285 Fortunately, Exim does not actually use EX_OK. The code used to try to
3286 preserve the sysexits.h value, by assumimg that macro definitions were
3287 scanned for macro replacements. I have been disabused of this notion,
3288 so now the code just undefines EX_OK before #including unistd.h.

PH
3290PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3291 in the smtp transport. When a block could not be written in a single
3292 write() function, the timeout was being re-applied to each part-write.
3293 This seems wrong - if the receiver was accepting one byte at a time it
3294 would take for ever. The timeout is now adjusted when this happens. It
3295 doesn't have to be particularly precise.

3324TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.

3327 obviously out-of-the-box. Patch from Alex Miller.

3333PH/09 The syntax error of a character other than { following "${if
3334 def:variable_name" (after optional whitespace) was not being diagnosed.
3335 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3336 accidental colon was present, for example, could give incorrect results.
