JH
10JH/02 The smtp transport option "multi_domain" is now expanded.
11
ad07e9ad
JH
12JH/03 The smtp transport now requests PRDR by default, if the server offers
13 it.
14
01a4a5c5
JH
15JH/04 Certificate name checking on server certificates, when exim is a client,
16 is now done by default. The transport option tls_verify_cert_hostname
17 can be used to disable this per-host. The build option
18 EXPERIMENTAL_CERTNAMES is withdrawn.
19
cb1d7830 20JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 21 default to the word "system" to access the system default CA bundle.

JH
22 For GnuTLS, only version 3.0.20 or later.
23
610ff438 24JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19

25 (but not required) by default. The verification status is now logged by
26 default, for both outbound TLS and client-certificate supplying inbound
27 TLS connections
610ff438 28
f926e272
JH
29JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
30 sites use this now.
31
50dc7409
JH
32JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
33 Status Notification (bounce) messages are now MIME format per RFC 3464.
34 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
35 under the control of the dsn_advertise_hosts option, and routers may
36 have a dsn_lasthop option.
37
0f0c8159
JH
38JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
39 default, modifiable by a malware= option. The list separator for
23763898 40 the options can now be changed in the usual way. Bug 68.
4e71661f 41
1ad6489e
JH
42JH/10 The smtp_receive_timeout main option is now expanded before use.
43

AL
53JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
54 Patch from Andrew Lewis.
55
fd4d8871 56JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 57 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
58 modifiers per server. Patch originally by <rommer@active.by>.
59
60JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
61 and remote servers. Remote servers can be IPv6 addresses, and
62 specify a port-range.
fd4d8871 63

98

JH
99JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
100 Normally benign, it bites when the pair was led to by a CNAME;
101 modern usage is to not canoicalize the domain to a CNAME target
102 (and we were inconsistent anyway for A-only vs AAAA+A).

107Exim version 4.85
108-----------------
109TL/01 When running the test suite, the README says that variables such as
110 no_msglog_check are global and can be placed anywhere in a specific
111 test's script, however it was observed that placement needed to be near
112 the beginning for it to behave that way. Changed the runtest perl
113 script to read through the entire script once to detect and set these
114 variables, reset to the beginning of the script, and then run through
115 the script parsing/test process like normal.
116
ac20058f
TL
117TL/02 The BSD's have an arc4random API. One of the functions to induce
118 adding randomness was arc4random_stir(), but it has been removed in
119 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
120 function when detected.
121
a9b8ec8b
JH
122JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
123 cause callback expansion.
124
6286d7c4
TL
125TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
126 syntax errors in an expansion can be treated as a string instead of
127 logging or causing an error, due to the internal use of bool_lax
128 instead of bool when processing it.
129
0f06b4f2 130JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
131 server certificates when making smtp deliveries.

140 Merged patch from Sebastian Wiedenroth.
e449c3b0 141
bd21a787
WB
142JH/05 Fix results-pipe from transport process. Several recipients, combined
143 with certificate use, exposed issues where response data items split
144 over buffer boundaries were not parsed properly. This eventually
145 resulted in duplicates being sent. This issue only became common enough
146 to notice due to the introduction of conection certificate information,
147 the item size being so much larger. Found and fixed by Wolfgang Breyha.
148
8bc732e8
JH
149JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
150 size buffer was used, resulting in syntax errors when an expansion
151 exceeded it.
152
a7fec7a7
JH
153JH/07 Add support for directories of certificates when compiled with a GnuTLS
154 version 3.3.6 or later.
155
774ef2d7
JH
156JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
157 is EXPERIMENTAL_EVENT, the main-configuration and transport options
158 both become "event_action", the variables become $event_name, $event_data
aec45841 159 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
160 routers, transports and related events. The tls:cert event is now also
161 raised for inbound connections, if the main configuration event_action
162 option is defined.
774ef2d7 163
eca4debb
TL
164TL/06 In test suite, disable OCSP for old versions of openssl which contained
165 early OCSP support, but no stapling (appears to be less than 1.0.0).
166
8d692470
JH
167JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
168 server certificate names available under the smtp transport option
169 "tls_verify_cert_hostname" now do not permit multi-component wildcard
170 matches.
171
e9477a08
JH
172JH/10 Time-related extraction expansions from certificates now use the main
173 option "timezone" setting for output formatting, and are consistent
174 between OpenSSL and GnuTLS compilations. Bug 1541.

216Exim version 4.83
217-----------------
218
219TF/01 Correctly close the server side of TLS when forking for delivery.
220
221 When a message was received over SMTP with TLS, Exim failed to clear up
222 the incoming connection properly after forking off the child process to
223 deliver the message. In some situations the subsequent outgoing
224 delivery connection happened to have the same fd number as the incoming
225 connection previously had. Exim would try to use TLS and fail, logging
226 a "Bad file descriptor" error.

257 results permerror and temperror. Previous values are deprecated but
258 still accepted. In a future release, err_perm and err_temp will be
259 completely removed, which will be a backward incompatibility if the
260 ACL tests for either of these two old results. Patch contributed by

285JH/12 Expand items in router/transport headers_add or headers_remove lists
286 individually rather than the list as a whole. Bug 1452.
287
288 Required for reasonable handling of multiple headers_ options when
289 they may be empty; requires that headers_remove items with embedded
290 colons must have them doubled (or the list-separator changed).

472TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
473
474 When a queue runner is handling a message, Exim first routes the
475 recipient addresses, during which it prunes them based on the retry
476 hints database. After that it attempts to deliver the message to
477 any remaining recipients. It then updates the hints database using
478 the retry rules.
479
480 So if a recipient address works intermittently, it can get repeatedly
481 deferred at routing time. The retry hints record remains fresh so the
482 address never reaches the final cutoff time.
483
484 This is a fairly common occurrence when a user is bumping up against
485 their storage quota. Exim had some logic in its local delivery code
486 to deal with this. However it did not apply to per-recipient defers
487 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
488
1ddeb334
TF
489 This change adds a proper retry rule check during routing so that the
490 final cutoff time is checked against the message's age. We only do
491 this check if there is an address retry record and there is not a
492 domain retry record; this implies that previous attempts to handle
493 the address had the retry_use_local_parts option turned on. We use
494 this as an approximation for the destination being like a local
495 delivery, as in LMTP.
67bd1ab3
TF
496
497 I suspect this new check makes the old local delivery cutoff check
498 redundant, but I have not verified this so I left the code in place.

505
506 When I ran the test suite under the user fanf2, Exim expanded
507 the header to contain my full name, whereas it should have added
508 a Resent-Sender: header. It erroneously treats any prefix of the
509 username as equal to the username.

532JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
533 Server implementation by Todd Lyons, client by JH.
534 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
535 config variable "prdr_enable" controls whether the server
536 advertises the facility. If the client requests PRDR a new
537 acl_data_smtp_prdr ACL is called once for each recipient, after
538 the body content is received and before the acl_smtp_data ACL.
539 The client is controlled by bolth of: a hosts_try_prdr option
540 on the smtp transport, and the server advertisement.
541 Default client logging of deliveries and rejections involving
542 PRDR are flagged with the string "PRDR".

820TF/03 Make the exiwhat support code safe for signals. Previously Exim might
821 lock up or crash if it happened to be inside a call to libc when it
822 got a SIGUSR1 from exiwhat.
823
824 The SIGUSR1 handler appends the current process status to the process
825 log which is later printed by exiwhat. It used to use the general
826 purpose logging code to do this, but several functions it calls are
827 not safe for signals.
828
829 The new output code in the SIGUSR1 handler is specific to the process
830 log, and simple enough that it's easy to inspect for signal safety.
831 Removing some special cases also simplifies the general logging code.
832 Removing the spurious timestamps from the process log simplifies
833 exiwhat.

835TF/04 Improved ratelimit ACL condition.
836
837 The /noupdate option has been deprecated in favour of /readonly which
838 has clearer semantics. The /leaky, /strict, and /readonly update modes
839 are mutually exclusive. The update mode is no longer included in the
840 database key; it just determines when the database is updated. (This
841 means that when you upgrde Exim will forget old rate measurements.)
842
843 Exim now checks that the per_* options are used with an update mode that
844 makes sense for the current ACL. For example, when Exim is processing a
845 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
846 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
847 must specify per_mail/readonly. If you omit the update mode it defaults to
848 /leaky where that makes sense (as before) or /readonly where required.
849
850 The /noupdate option is now undocumented but still supported for
851 backwards compatibility. It is equivalent to /readonly except that in
852 ACLs where /readonly is required you may specify /leaky/noupdate or
853 /strict/noupdate which are treated the same as /readonly.
854
855 A useful new feature is the /count= option. This is a generalization
856 of the per_byte option, so that you can measure the throughput of other
857 aggregate values. For example, the per_byte option is now equivalent
858 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
859
860 The per_rcpt option has been generalized using the /count= mechanism
861 (though it's more complicated than the per_byte equivalence). When it is
862 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
863 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
864 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
865 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
866 Note that using per_rcpt with a non-readonly update mode in more than
867 one ACL will cause the recipients to be double-counted. (The per_mail
868 and per_byte options don't have this problem.)
869
870 The handling of very low rates has changed slightly. If the computed rate
871 is less than the event's count (usually one) then this event is the first
872 after a long gap. In this case the rate is set to the same as this event's
873 count, so that the first message of a spam run is counted properly.
874
875 The major new feature is a mechanism for counting the rate of unique
876 events. The new per_addr option counts the number of different
877 recipients that someone has sent messages to in the last time period. It
878 behaves like per_rcpt if all the recipient addresses are different, but
879 duplicate recipient addresses do not increase the measured rate. Like
880 the /count= option this is a general mechanism, so the per_addr option
881 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
882 example, measure the rate that a client uses different sender addresses
883 with the options per_mail/unique=$sender_address. There are further
884 details in the main documentation.

1434 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1435 were called 'true' and it seems that C99 defines that as a reserved

1437 not include C99-style headers which use bools without triggering

1454-----------------
1455
1456PH/01 Another patch from the Sieve maintainer.
1457
6a3bceb1
PH
1458PH/02 When an IPv6 address is converted to a string for single-key lookup
1459 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1460 dots are used instead of colons so that keys in lsearch files need not
1461 contain colons. This was done some time before quoting was made available
1462 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1463 (notated using the quote facility) so as to distinguish them from IPv4
1464 keys. This meant that lookups for IP addresses in host lists did not work
1465 for iplsearch lookups.
1466
1467 This has been fixed by arranging for IPv6 addresses to be expressed with
1468 colons if the lookup type is iplsearch. This is not incompatible, because
1469 previously such lookups could never work.
1470
1471 The situation is now rather anomolous, since one *can* have colons in
1472 ordinary lsearch keys. However, making the change in all cases is
1473 incompatible and would probably break a number of configurations.

MH
1478MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1479 conversion specification without a maximum field width, thereby enabling
1480 a rogue spamd server to cause a buffer overflow. While nobody in their
1481 right mind would setup Exim to query an untrusted spamd server, an
1482 attacker that gains access to a server running spamd could potentially
1483 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1488MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1489 a directory entry by the name of the lookup key. Previously, if a
1490 symlink pointed to a non-existing file or a file in a directory that
1491 Exim lacked permissions to read, a lookup for a key matching that
1492 symlink would fail. Now it is enough that a matching directory entry
1493 exists, symlink or not. (Bugzilla 503.)

PH
1676PH/29 SMTP synchronization checks are implemented when a command is read -
1677 there is a check that no more input is waiting when there shouldn't be
1678 any. However, for some commands, a delay in an ACL can mean that it is
1679 some time before the response is written. In this time, more input might
1680 arrive, invalidly. So now there are extra checks after an ACL has run for
1681 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1682 pipelining has not been advertised.

1697 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1698 was a macro that became an assignment, so it seemed to work. This has

1731 started the daemon, but after a SIGHUP it used the Exim user (because it

1738 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1756 the response to the final '.' that terminates a message, but only in the
1757 case where the client has not sent further data following the '.'
1758 (unfortunately, this is allowed). However, in many cases there won't be
1759 any further data because there won't be any more messages to send. A call
1760 to select() can be used: if it shows that the input is "ready", there is
1761 either input waiting, or the socket has been closed. An attempt to read
1762 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1763 would have sent an OK response which the client would never have see.

1774PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1775 fixed by 4.65/MH/01 (is this a record?) are fixed:
1776
1777 (i) An empty string was always treated as zero by the numeric comparison
1778 operators. This behaviour has been restored.
1779
1780 (ii) It is documented that the numeric comparison operators always treat
1781 their arguments as decimal numbers. This was broken in that numbers
1782 starting with 0 were being interpreted as octal.
1783
1784 While fixing these problems I realized that there was another issue that
1785 hadn't been noticed. Values of message_size_limit (both the global option
1786 and the transport option) were treated as octal if they started with 0.
1787 The documentation was vague. These values are now always treated as
1788 decimal, and I will make that clear in the documentation.

1802PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1803 child addresses, Exim now panics and dies. Previously, because the count
1804 is held in a short int, deliveries were likely to be lost. As such a
1805 large number of recipients for a single message is ridiculous
1806 (performance will be very, very poor), I have chosen to impose a limit
1807 rather than extend the field.

1813TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1814 leftover -K file (the existence of which was triggered by #402).

1823TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1832PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1833 callout verification, Exim cached a "reject" for the entire domain. This
1834 is correct for most verifications, but it is not correct for a recipient
1835 verification with use_sender or use_postmaster set, because in that case
1836 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1837 case of MAIL FROM:<> rejection from other early rejections (e.g.
1838 rejection of HELO). When verifying a recipient using a non-null MAIL
1839 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1840 Whatever the result of the callout, the value of the domain cache is
1841 left unchanged (for any other kind of callout, getting as far as trying
1842 RCPT means that the domain itself is ok).

1876PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1878 probably the interface on which it is arriving) and not to the outgoing
1879 callout (which could be using a different interface). This has been
1880 changed to use the value of the helo_data option from the smtp transport
1881 instead - this is what is used when a message is actually being sent. If
1882 there is no remote transport (possible with a router that sets up host
1883 addresses), $smtp_active_hostname is used.

7befa435 1886 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1887 (a) The code assumed that strncpy() returns a negative number on buffer
1888 overflow, which isn't the case. Replaced with Exim's string_format()
1889 function.
1890 (b) There were several signed/unsigned issues. I just did the minimum
1891 hacking in of casts. There is scope for a larger refactoring.
1892 (c) The code used strcasecmp() which is not a standard C function.
1893 Replaced with Exim's strcmpic() function.
1894 (d) The code set only $1; it now sets $auth1 as well.
1895 (e) A simple test gave the error "authentication client didn't specify
1896 service in request". It would seem that Dovecot has changed its
1897 interface. Fortunately there's a specification; I followed it and
1898 changed what the client sends and it appears to be working now.

1903PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1904 address A is aliased to B and C, where B exists and C does not. Without
1905 -v the output is "A verified" because verification stops after a
1906 successful redirection if more than one address is generated. However,
1907 with -v the child addresses are also verified. Exim was outputting "A
1908 failed to verify" and then showing the successful verification for C,
1909 with its parentage. It now outputs "B failed to verify", showing B's
1910 parentage before showing the successful verification of C.

1915
322050c2
PH
1916PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1917 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1918 they consult the DNS. I had assumed they would set it the way they
1919 wanted; and indeed my experiments on Linux seem to show that in some
1920 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1921 To be on the safe side, however, I have now made the interface to
1922 host_find_byname() similar to host_find_bydns(), with an argument
1923 containing the DNS resolver options. The host_find_byname() function now
1924 sets these options at its start, just as host_find_bydns() does. The smtp
1925 transport options dns_qualify_single and dns_search_parents are passed to
1926 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1927 of host_find_byname() use the default settings of RES_DEFNAMES
1928 (qualify_single) but not RES_DNSRCH (search_parents).

1930PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1931 spool_read_header() do less string testing, by means of a preliminary
1932 switch on the second character of optional "-foo" lines. (This is
1933 overdue, caused by the large number of possibilities that now exist.
1934 Originally there were few.) While I was there, I also converted the
1935 str(n)cmp tests so they don't re-test the leading "-" and the first
1936 character, in the hope this might squeeze out yet more improvement.

1938PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1939 flag allowing group syntax was set by the header_syntax check but not
1940 turned off, possible causing trouble later; (2) The flag was not being
1941 set at all for the header_verify test, causing "group"-style headers to
1942 be rejected. I have now set it in this case, and also caused header_
1943 verify to ignore an empty address taken from a group. While doing this, I
1944 came across some other cases where the code for allowing group syntax
1945 while scanning a header line wasn't quite right (mostly, not resetting
1946 the flag correctly in the right place). These bugs could have caused
1947 trouble for malformed header lines. I hope it is now all correct.

PH
1949PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1950 with the "reply" argument non-NULL. The code, however (which originally

1952 but it didn't always do it. This confused somebody who was copying the
1953 code for some other use. I have removed all the tests.

PH
1955PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1956 feature that was used to support insecure browsers during the U.S. crypto
1957 embargo. It requires special client support, and Exim is probably the

1963PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1964 authenticator to fail if there's a tab character in the incoming data

1966 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1967 if the connection is using TLS or if the remote IP is the same as the
1968 local IP, and the "valid-client-cert option" if a client certificate has
1969 been verified.

2001PH/30 Exim was sometimes attempting to deliver messages that had suffered
2002 address errors (4xx response to RCPT) over the same connection as other
2003 messages routed to the same hosts. Such deliveries are always "forced",
2004 so retry times are not inspected. This resulted in far too many retries
2005 for the affected addresses. The effect occurred only when there were more
2006 hosts than the hosts_max_try setting in the smtp transport when it had
2007 the 4xx errors. Those hosts that it had tried were not added to the list
2008 of hosts for which the message was waiting, so if all were tried, there
2009 was no problem. Two fixes have been applied:
2010
2011 (i) If there are any address or message errors in an SMTP delivery, none
2012 of the hosts (tried or untried) are now added to the list of hosts
2013 for which the message is waiting, so the message should not be a
2014 candidate for sending over the same connection that was used for a
2015 successful delivery of some other message. This seems entirely
2016 reasonable: after all the message is NOT "waiting for some host".
2017 This is so "obvious" that I'm not sure why it wasn't done
2018 previously. Hope I haven't missed anything, but it can't do any
2019 harm, as the worst effect is to miss an optimization.
2020
2021 (ii) If, despite (i), such a delivery is accidentally attempted, the
2022 routing retry time is respected, so at least it doesn't keep
2023 hammering the server.

2038PH/35 The error "getsockname() failed: connection reset by peer" was being
2039 written to the panic log as well as the main log, but it isn't really
2040 panic-worthy as it just means the connection died rather early on. I have
2041 removed the panic log writing for the ECONNRESET error when getsockname()
2042 fails.
2043
48c7f9e2
PH
2044PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2045 runs only) independently of the message's sender address. This meant
2046 that, if the 4xx error was in fact related to the sender, a different
2047 message to the same recipient with a different sender could confuse
2048 things. In particualar, this can happen when sending to a greylisting
2049 server, but other circumstances could also provoke similar problems.
2050 I have changed the default so that the retry time for these errors is now
2051 based a combination of the sender and recipient addresses. This change
2052 can be overridden by setting address_retry_include_sender=false in the
2053 smtp transport.

2325 kind of temporary error. A kludge has been added to help with this.
2326 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2327 554 error is used if errno is still zero or contains ENOENT (which occurs

2351PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2352 folder from quota calculations, a direct delivery into this folder messed
2353 up the contents of the maildirsize file. This was because the regex was
2354 used only to exclude .Trash (or whatever) when the size of the mailbox
2355 was calculated. There was no check that a delivery was happening into an
2356 excluded directory. This bug has been fixed by ignoring all quota
2357 processing for deliveries into excluded directories.

2364
2365PH/01 The code for finding all the local interface addresses on a FreeBSD
2366 system running IPv6 was broken. This may well have applied to all BSD
2367 systems, as well as to others that have similar system calls. The broken
2368 code found IPv4 interfaces correctly, but gave incorrect values for the
2369 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2370 that it would not match correctly against @[] and not recognize the IPv6
2371 addresses as local.

2414 autoreply, Exim could try to deliver to a non-existent relative file

2437 (a) Failures to set uid/gid, the current directory, or a process leader
2438 in a subprocess such as that created by queryprogram now generate
2439 suitable debugging ouput when -d is set.

2448PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2449 additional section of a DNS packet that returns MX or SRV records.
2450 Instead, it always explicitly searches for A/AAAA records. This avoids
2451 major problems that occur when a DNS server includes only records of one
2452 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2453 fixed another bug: if SRV records were looked up and the corresponding
2454 address records were *not* found in the additional section, the port
2455 values from the SRV records were lost.

PH
2465PH/19 When calculating a retry time, Exim used to measure the "time since
2466 failure" by looking at the "first failed" field in the retry record. Now
2467 it does not use this if it is later than than the arrival time of the
2468 message. Instead it uses the arrival time. This makes for better
2469 behaviour in cases where some deliveries succeed, thus re-setting the
2470 "first failed" field. An example is a quota failure for a huge message
2471 when small messages continue to be delivered. Without this change, the
2472 "time since failure" will always be short, possible causing more frequent
2473 delivery attempts for the huge message than are intended.

PH
2570PH/42 The content-scanning code uses fopen() to create files in which to put
2571 message data. Previously it was not paying any attention to the mode of
2572 the files. Exim runs with umask(0) because the rest of the code creates
2573 files with open(), and sets the required mode explicitly. Thus, these
2574 files were ending up world-writeable. This was not a big issue, because,
2575 being within the spool directory, they were not world-accessible. I have
2576 created a function called modefopen, which takes an additional mode
2577 argument. It sets umask(777), creates the file, chmods it to the required
2578 mode, then resets the umask. All the relevant calls to fopen() in the
2579 content scanning code have been changed to use this function.

2591 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2616
2617 (i) Exim was not creating retry information for temporary errors given
2618 for individual recipients after the DATA command when the smtp transport
2619 was used in LMTP mode. This meant that they could be retried too
2620 frequently, and not timed out correctly.
2621
2622 (ii) Exim was setting the flag that allows error details to be returned
2623 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2624 recipients that were returned after the DATA command.
2625
2626PH/53 This is related to PH/52, but is more general: for any failing address,
2627 when detailed error information was permitted to be returned to the

2700PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2701 function verify_get_ident() calls ip_connect() to connect a socket, but
2702 if the "connect()" function timed out, ip_connect() used to close the
2703 socket. However, verify_get_ident() also closes the socket later, and in
2704 between Exim writes to the log, which may get opened at this point. When
2705 the socket was closed in ip_connect(), the log could get the same file
2706 descriptor number as the socket. This naturally causes chaos. The fix is
2707 not to close the socket in ip_connect(); the socket should be closed by
2708 the function that creates it. There was only one place in the code where
2709 this was missing, in the iplookup router, which I don't think anybody now
2710 uses, but I've fixed it anyway.

2766PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2767 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2768 not being looked up in the rDNS to get a host name, Exim was showing the
2769 IP address twice in Received: lines, even though the IP addresses were
2770 identical. For example:
2771
2772 Received: from [1.2.3.4] (helo=[1.2.3.4])
2773
2774 However, if the real host name was known, it was omitting the HELO data
2775 if it matched the actual IP address. This has been tidied up so that it
2776 doesn't show the same IP address twice.

2802PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2804
2805 Auto-submitted: auto-generated
2806
2807 in the messages that it generates (bounce messages and others, such as
2808 warnings). In the case of bounce messages for non-SMTP mesages, there was
2809 also a typo: it was using "Auto_submitted" (underscore instead of
2810 hyphen). Since every message generated by Exim is necessarily in response
2811 to another message, thes have all been changed to:
2812
2813 Auto-Submitted: auto-replied
2814
2815 in accordance with these statements in the RFC:
2816
2817 The auto-replied keyword:
2818
2819 - SHOULD be used on messages sent in direct response to another
2820 message by an automatic process,
2821

2865PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2866 canonical form (as documented). However, after a host name lookup from
2867 the IP address, check_host() was doing a simple string comparison with
2868 addresses acquired from the DNS when checking that the found name did
2869 have the original IP as one of its addresses. Since any found IPv6
2870 addresses are likely to be in abbreviated form, the comparison could
2871 fail. Luckily, there already exists a function for doing the comparison
2872 by converting both addresses to binary, so now that is used instead of
2873 the text comparison.

2875PH/20 There was another similar case to PH/19, when a complete host name was

3150 "warn" verbs). This seems wrong, so I have changed it.

3152TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3153 it should not have, which might have caused a crash in the right
3154 circumstances, but probably never did.

3170PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3171 with the definition in sysexits.h (which is #included earlier).
3172 Fortunately, Exim does not actually use EX_OK. The code used to try to
3173 preserve the sysexits.h value, by assumimg that macro definitions were
3174 scanned for macro replacements. I have been disabused of this notion,
3175 so now the code just undefines EX_OK before #including unistd.h.

PH
3177PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3178 in the smtp transport. When a block could not be written in a single
3179 write() function, the timeout was being re-applied to each part-write.
3180 This seems wrong - if the receiver was accepting one byte at a time it
3181 would take for ever. The timeout is now adjusted when this happens. It
3182 doesn't have to be particularly precise.

3248PH/15 The code I had for printing potentially long long variables in PH/11

c6c2dc1d
PH
3251 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3252 to be "long long int" or "long int". This is needed for the internal
3253 formatting function string_vformat().

3255PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3256 the configuration file to be ":syslog", then the script "guesses" where
3257 the logs files are, rather than using the compiled in default. In our
3258 case the guess is not the same as the compiled default, so the script
3259 suddenly stopped working when I started to use syslog. The patch checks
3260 to see if log_file_path is "". If so, it attempts to read it from exim
3261 with no configuration file to get the compiled in version, before it
3262 falls back to the previous guessing code."

3271PH/18 If the "use_postmaster" option was set for a recipient callout together

3276PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3277 patch removes a few documentation additions to RFC 3028, because the
3278 latest draft now contains them. It adds the new en;ascii-case comparator
3279 and a new error check for 8bit text in MIME parts. Comparator and
3280 require names are now matched exactly. I enabled the subaddress
3281 extension, but it is not well tested yet (read: it works for me)."

3311 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3312 picked up on a user's system that detects such things. There doesn't seem
3313 to be a gcc warning option for this - only an attribute that has to be
3314 put on the function's prototype. It seems that in Fedora Core 4 they have
3315 set this on a number of new functions. No doubt there will be more in due
3316 course.

PH
3318PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3319 specify a transport. However, if an address that was verified by such a
3320 router was the subject of a callout, Exim crashed because it tried to
3321 read the rcpt_include_affixes from the non-existent transport. Now it
3322 just assumes that the setting of that option is false. This bug was
3323 introduced by 4.51/PH/31.

3333PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3334 aren't the modern standard, and it seems that some systems' include files
3335 don't always have them. Exim was already checking for some of the newer
3336 ones like T_AAAA, and defining it itself. I've added checks for all the
3337 record types that Exim uses.

PH
3339PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3340 not automatically generating a new one, as it is supposed to. This
3341 prevented TLS from working. If the file did exist, but contained invalid
3342 data, a new version was generated, as expected. It was only the case of a
3343 non-existent file that was broken.
