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18 EXPERIMENTAL_CERTNAMES is withdrawn.

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

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

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).

113Exim version 4.85
114-----------------
115TL/01 When running the test suite, the README says that variables such as
116 no_msglog_check are global and can be placed anywhere in a specific
117 test's script, however it was observed that placement needed to be near
118 the beginning for it to behave that way. Changed the runtest perl
119 script to read through the entire script once to detect and set these
120 variables, reset to the beginning of the script, and then run through
121 the script parsing/test process like normal.

123TL/02 The BSD's have an arc4random API. One of the functions to induce
124 adding randomness was arc4random_stir(), but it has been removed in
125 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
126 function when detected.

JH
128JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
129 cause callback expansion.

TL
131TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
132 syntax errors in an expansion can be treated as a string instead of
133 logging or causing an error, due to the internal use of bool_lax
134 instead of bool when processing it.

WB
148JH/05 Fix results-pipe from transport process. Several recipients, combined
149 with certificate use, exposed issues where response data items split
150 over buffer boundaries were not parsed properly. This eventually
151 resulted in duplicates being sent. This issue only became common enough
152 to notice due to the introduction of conection certificate information,
153 the item size being so much larger. Found and fixed by Wolfgang Breyha.
154
8bc732e8
JH
155JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
156 size buffer was used, resulting in syntax errors when an expansion
157 exceeded it.

159JH/07 Add support for directories of certificates when compiled with a GnuTLS
160 version 3.3.6 or later.
161
774ef2d7
JH
162JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
163 is EXPERIMENTAL_EVENT, the main-configuration and transport options
164 both become "event_action", the variables become $event_name, $event_data
aec45841 165 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
166 routers, transports and related events. The tls:cert event is now also
167 raised for inbound connections, if the main configuration event_action
168 option is defined.

224
225TF/01 Correctly close the server side of TLS when forking for delivery.
226
227 When a message was received over SMTP with TLS, Exim failed to clear up
228 the incoming connection properly after forking off the child process to
229 deliver the message. In some situations the subsequent outgoing
230 delivery connection happened to have the same fd number as the incoming
231 connection previously had. Exim would try to use TLS and fail, logging
232 a "Bad file descriptor" error.

478TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
479
480 When a queue runner is handling a message, Exim first routes the
481 recipient addresses, during which it prunes them based on the retry
482 hints database. After that it attempts to deliver the message to
483 any remaining recipients. It then updates the hints database using
484 the retry rules.
485
486 So if a recipient address works intermittently, it can get repeatedly
487 deferred at routing time. The retry hints record remains fresh so the
488 address never reaches the final cutoff time.
489
490 This is a fairly common occurrence when a user is bumping up against
491 their storage quota. Exim had some logic in its local delivery code
492 to deal with this. However it did not apply to per-recipient defers
493 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
494
1ddeb334
TF
495 This change adds a proper retry rule check during routing so that the
496 final cutoff time is checked against the message's age. We only do
497 this check if there is an address retry record and there is not a
498 domain retry record; this implies that previous attempts to handle
499 the address had the retry_use_local_parts option turned on. We use
500 this as an approximation for the destination being like a local
501 delivery, as in LMTP.
67bd1ab3
TF
502
503 I suspect this new check makes the old local delivery cutoff check
504 redundant, but I have not verified this so I left the code in place.

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

539 Server implementation by Todd Lyons, client by JH.
540 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
541 config variable "prdr_enable" controls whether the server
542 advertises the facility. If the client requests PRDR a new
543 acl_data_smtp_prdr ACL is called once for each recipient, after
544 the body content is received and before the acl_smtp_data ACL.
545 The client is controlled by bolth of: a hosts_try_prdr option
546 on the smtp transport, and the server advertisement.
547 Default client logging of deliveries and rejections involving
548 PRDR are flagged with the string "PRDR".

826TF/03 Make the exiwhat support code safe for signals. Previously Exim might
827 lock up or crash if it happened to be inside a call to libc when it
828 got a SIGUSR1 from exiwhat.
829
830 The SIGUSR1 handler appends the current process status to the process
831 log which is later printed by exiwhat. It used to use the general
832 purpose logging code to do this, but several functions it calls are
833 not safe for signals.
834
835 The new output code in the SIGUSR1 handler is specific to the process
836 log, and simple enough that it's easy to inspect for signal safety.
837 Removing some special cases also simplifies the general logging code.
838 Removing the spurious timestamps from the process log simplifies
839 exiwhat.

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

1441 were called 'true' and it seems that C99 defines that as a reserved

1460-----------------
1461
1462PH/01 Another patch from the Sieve maintainer.
1463
6a3bceb1
PH
1464PH/02 When an IPv6 address is converted to a string for single-key lookup
1465 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1466 dots are used instead of colons so that keys in lsearch files need not
1467 contain colons. This was done some time before quoting was made available
1468 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1469 (notated using the quote facility) so as to distinguish them from IPv4
1470 keys. This meant that lookups for IP addresses in host lists did not work
1471 for iplsearch lookups.
1472
1473 This has been fixed by arranging for IPv6 addresses to be expressed with
1474 colons if the lookup type is iplsearch. This is not incompatible, because
1475 previously such lookups could never work.
1476
1477 The situation is now rather anomolous, since one *can* have colons in
1478 ordinary lsearch keys. However, making the change in all cases is
1479 incompatible and would probably break a number of configurations.

MH
1484MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1485 conversion specification without a maximum field width, thereby enabling
1486 a rogue spamd server to cause a buffer overflow. While nobody in their
1487 right mind would setup Exim to query an untrusted spamd server, an
1488 attacker that gains access to a server running spamd could potentially
1489 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1494MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1495 a directory entry by the name of the lookup key. Previously, if a
1496 symlink pointed to a non-existing file or a file in a directory that
1497 Exim lacked permissions to read, a lookup for a key matching that
1498 symlink would fail. Now it is enough that a matching directory entry
1499 exists, symlink or not. (Bugzilla 503.)

1682PH/29 SMTP synchronization checks are implemented when a command is read -
1683 there is a check that no more input is waiting when there shouldn't be
1684 any. However, for some commands, a delay in an ACL can mean that it is
1685 some time before the response is written. In this time, more input might
1686 arrive, invalidly. So now there are extra checks after an ACL has run for
1687 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1688 pipelining has not been advertised.

PH
1762 the response to the final '.' that terminates a message, but only in the
1763 case where the client has not sent further data following the '.'
1764 (unfortunately, this is allowed). However, in many cases there won't be
1765 any further data because there won't be any more messages to send. A call
1766 to select() can be used: if it shows that the input is "ready", there is
1767 either input waiting, or the socket has been closed. An attempt to read
1768 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1769 would have sent an OK response which the client would never have see.

1780PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1781 fixed by 4.65/MH/01 (is this a record?) are fixed:
1782
1783 (i) An empty string was always treated as zero by the numeric comparison
1784 operators. This behaviour has been restored.
1785
1786 (ii) It is documented that the numeric comparison operators always treat
1787 their arguments as decimal numbers. This was broken in that numbers
1788 starting with 0 were being interpreted as octal.
1789
1790 While fixing these problems I realized that there was another issue that
1791 hadn't been noticed. Values of message_size_limit (both the global option
1792 and the transport option) were treated as octal if they started with 0.
1793 The documentation was vague. These values are now always treated as
1794 decimal, and I will make that clear in the documentation.

1808PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

1810 is held in a short int, deliveries were likely to be lost. As such a
1811 large number of recipients for a single message is ridiculous
1812 (performance will be very, very poor), I have chosen to impose a limit
1813 rather than extend the field.

1820 leftover -K file (the existence of which was triggered by #402).

1829TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1838PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1839 callout verification, Exim cached a "reject" for the entire domain. This
1840 is correct for most verifications, but it is not correct for a recipient
1841 verification with use_sender or use_postmaster set, because in that case
1842 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1843 case of MAIL FROM:<> rejection from other early rejections (e.g.
1844 rejection of HELO). When verifying a recipient using a non-null MAIL
1845 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1846 Whatever the result of the callout, the value of the domain cache is
1847 left unchanged (for any other kind of callout, getting as far as trying
1848 RCPT means that the domain itself is ok).

1882PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1884 probably the interface on which it is arriving) and not to the outgoing
1885 callout (which could be using a different interface). This has been
1886 changed to use the value of the helo_data option from the smtp transport
1887 instead - this is what is used when a message is actually being sent. If
1888 there is no remote transport (possible with a router that sets up host
1889 addresses), $smtp_active_hostname is used.

7befa435 1892 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1893 (a) The code assumed that strncpy() returns a negative number on buffer
1894 overflow, which isn't the case. Replaced with Exim's string_format()
1895 function.
1896 (b) There were several signed/unsigned issues. I just did the minimum
1897 hacking in of casts. There is scope for a larger refactoring.
1898 (c) The code used strcasecmp() which is not a standard C function.
1899 Replaced with Exim's strcmpic() function.
1900 (d) The code set only $1; it now sets $auth1 as well.
1901 (e) A simple test gave the error "authentication client didn't specify
1902 service in request". It would seem that Dovecot has changed its
1903 interface. Fortunately there's a specification; I followed it and
1904 changed what the client sends and it appears to be working now.

1910 address A is aliased to B and C, where B exists and C does not. Without
1911 -v the output is "A verified" because verification stops after a
1912 successful redirection if more than one address is generated. However,
1913 with -v the child addresses are also verified. Exim was outputting "A
1914 failed to verify" and then showing the successful verification for C,
1915 with its parentage. It now outputs "B failed to verify", showing B's
1916 parentage before showing the successful verification of C.

322050c2
PH
1922PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1923 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1924 they consult the DNS. I had assumed they would set it the way they
1925 wanted; and indeed my experiments on Linux seem to show that in some
1926 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1927 To be on the safe side, however, I have now made the interface to
1928 host_find_byname() similar to host_find_bydns(), with an argument
1929 containing the DNS resolver options. The host_find_byname() function now
1930 sets these options at its start, just as host_find_bydns() does. The smtp
1931 transport options dns_qualify_single and dns_search_parents are passed to
1932 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1933 of host_find_byname() use the default settings of RES_DEFNAMES
1934 (qualify_single) but not RES_DNSRCH (search_parents).

1937 spool_read_header() do less string testing, by means of a preliminary
1938 switch on the second character of optional "-foo" lines. (This is
1939 overdue, caused by the large number of possibilities that now exist.
1940 Originally there were few.) While I was there, I also converted the
1941 str(n)cmp tests so they don't re-test the leading "-" and the first
1942 character, in the hope this might squeeze out yet more improvement.

1944PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1945 flag allowing group syntax was set by the header_syntax check but not
1946 turned off, possible causing trouble later; (2) The flag was not being
1947 set at all for the header_verify test, causing "group"-style headers to
1948 be rejected. I have now set it in this case, and also caused header_
1949 verify to ignore an empty address taken from a group. While doing this, I
1950 came across some other cases where the code for allowing group syntax
1951 while scanning a header line wasn't quite right (mostly, not resetting
1952 the flag correctly in the right place). These bugs could have caused
1953 trouble for malformed header lines. I hope it is now all correct.

1957 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1958 but it didn't always do it. This confused somebody who was copying the

1961PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1962 feature that was used to support insecure browsers during the U.S. crypto
1963 embargo. It requires special client support, and Exim is probably the
1964 only MTA that supported it -- and would never use it because real RSA is
1965 always available. This code has been removed, because it had the bad
1966 effect of slowing Exim down by computing (never used) parameters for the
1967 RSA_EXPORT functionality.

1969PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1972 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1973 if the connection is using TLS or if the remote IP is the same as the
1974 local IP, and the "valid-client-cert option" if a client certificate has
1975 been verified.

2006
2007PH/30 Exim was sometimes attempting to deliver messages that had suffered
2008 address errors (4xx response to RCPT) over the same connection as other
2009 messages routed to the same hosts. Such deliveries are always "forced",
2010 so retry times are not inspected. This resulted in far too many retries
2011 for the affected addresses. The effect occurred only when there were more
2012 hosts than the hosts_max_try setting in the smtp transport when it had
2013 the 4xx errors. Those hosts that it had tried were not added to the list
2014 of hosts for which the message was waiting, so if all were tried, there
2015 was no problem. Two fixes have been applied:
2016
2017 (i) If there are any address or message errors in an SMTP delivery, none
2018 of the hosts (tried or untried) are now added to the list of hosts
2019 for which the message is waiting, so the message should not be a
2020 candidate for sending over the same connection that was used for a
2021 successful delivery of some other message. This seems entirely
2022 reasonable: after all the message is NOT "waiting for some host".
2023 This is so "obvious" that I'm not sure why it wasn't done
2024 previously. Hope I haven't missed anything, but it can't do any
2025 harm, as the worst effect is to miss an optimization.
2026
2027 (ii) If, despite (i), such a delivery is accidentally attempted, the
2028 routing retry time is respected, so at least it doesn't keep
2029 hammering the server.

2044PH/35 The error "getsockname() failed: connection reset by peer" was being
2045 written to the panic log as well as the main log, but it isn't really
2046 panic-worthy as it just means the connection died rather early on. I have
2047 removed the panic log writing for the ECONNRESET error when getsockname()
2048 fails.

48c7f9e2
PH
2050PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2051 runs only) independently of the message's sender address. This meant
2052 that, if the 4xx error was in fact related to the sender, a different
2053 message to the same recipient with a different sender could confuse
2054 things. In particualar, this can happen when sending to a greylisting
2055 server, but other circumstances could also provoke similar problems.
2056 I have changed the default so that the retry time for these errors is now
2057 based a combination of the sender and recipient addresses. This change
2058 can be overridden by setting address_retry_include_sender=false in the
2059 smtp transport.

2332 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2333 554 error is used if errno is still zero or contains ENOENT (which occurs

2357PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

2360 used only to exclude .Trash (or whatever) when the size of the mailbox
2361 was calculated. There was no check that a delivery was happening into an

2371PH/01 The code for finding all the local interface addresses on a FreeBSD
2372 system running IPv6 was broken. This may well have applied to all BSD
2373 systems, as well as to others that have similar system calls. The broken
2374 code found IPv4 interfaces correctly, but gave incorrect values for the
2375 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2376 that it would not match correctly against @[] and not recognize the IPv6
2377 addresses as local.

2456 Instead, it always explicitly searches for A/AAAA records. This avoids
2457 major problems that occur when a DNS server includes only records of one
2458 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2459 fixed another bug: if SRV records were looked up and the corresponding
2460 address records were *not* found in the additional section, the port
2461 values from the SRV records were lost.

PH
2471PH/19 When calculating a retry time, Exim used to measure the "time since
2472 failure" by looking at the "first failed" field in the retry record. Now
2473 it does not use this if it is later than than the arrival time of the
2474 message. Instead it uses the arrival time. This makes for better
2475 behaviour in cases where some deliveries succeed, thus re-setting the
2476 "first failed" field. An example is a quota failure for a huge message
2477 when small messages continue to be delivered. Without this change, the
2478 "time since failure" will always be short, possible causing more frequent
2479 delivery attempts for the huge message than are intended.

2576PH/42 The content-scanning code uses fopen() to create files in which to put
2577 message data. Previously it was not paying any attention to the mode of
2578 the files. Exim runs with umask(0) because the rest of the code creates
2579 files with open(), and sets the required mode explicitly. Thus, these
2580 files were ending up world-writeable. This was not a big issue, because,
2581 being within the spool directory, they were not world-accessible. I have
2582 created a function called modefopen, which takes an additional mode
2583 argument. It sets umask(777), creates the file, chmods it to the required
2584 mode, then resets the umask. All the relevant calls to fopen() in the
2585 content scanning code have been changed to use this function.

2623 (i) Exim was not creating retry information for temporary errors given

2625 was used in LMTP mode. This meant that they could be retried too
2626 frequently, and not timed out correctly.
2627
2628 (ii) Exim was setting the flag that allows error details to be returned
2629 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2630 recipients that were returned after the DATA command.
2631
2632PH/53 This is related to PH/52, but is more general: for any failing address,
2633 when detailed error information was permitted to be returned to the

2707 function verify_get_ident() calls ip_connect() to connect a socket, but
2708 if the "connect()" function timed out, ip_connect() used to close the
2709 socket. However, verify_get_ident() also closes the socket later, and in
2710 between Exim writes to the log, which may get opened at this point. When
2711 the socket was closed in ip_connect(), the log could get the same file
2712 descriptor number as the socket. This naturally causes chaos. The fix is
2713 not to close the socket in ip_connect(); the socket should be closed by
2714 the function that creates it. There was only one place in the code where
2715 this was missing, in the iplookup router, which I don't think anybody now

2735PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2736
2737 (1) Generate an error if the third argument for the ${prvs expansion is
2738 not a single digit.
2739
2740 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2741 string.
2742
2743 (3) Reset the variables that are obtained from the first argument of
2744 ${prvscheck and used in the second argument before leaving the code,
2745 because their memory is reclaimed, so using them afterwards may do
2746 silly things.
2747
2748 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2749 one (it's much easier than Tom thought :-).
2750
2751 (5) Because of (4), we can now allow for the use of $prvscheck_result
2752 inside the third argument.

2772PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2773 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2774 not being looked up in the rDNS to get a host name, Exim was showing the
2775 IP address twice in Received: lines, even though the IP addresses were
2776 identical. For example:
2777
2778 Received: from [1.2.3.4] (helo=[1.2.3.4])
2779
2780 However, if the real host name was known, it was omitting the HELO data
2781 if it matched the actual IP address. This has been tidied up so that it
2782 doesn't show the same IP address twice.

2810
2811 Auto-submitted: auto-generated
2812
2813 in the messages that it generates (bounce messages and others, such as
2814 warnings). In the case of bounce messages for non-SMTP mesages, there was
2815 also a typo: it was using "Auto_submitted" (underscore instead of
2816 hyphen). Since every message generated by Exim is necessarily in response
2817 to another message, thes have all been changed to:
2818
2819 Auto-Submitted: auto-replied
2820
2821 in accordance with these statements in the RFC:
2822
2823 The auto-replied keyword:
2824
2825 - SHOULD be used on messages sent in direct response to another
2826 message by an automatic process,
2827

2873 the IP address, check_host() was doing a simple string comparison with
2874 addresses acquired from the DNS when checking that the found name did
2875 have the original IP as one of its addresses. Since any found IPv6
2876 addresses are likely to be in abbreviated form, the comparison could
2877 fail. Luckily, there already exists a function for doing the comparison
2878 by converting both addresses to binary, so now that is used instead of
2879 the text comparison.

3144 command itself ended in error, the underlying message about the transport
3145 filter timeout was being overwritten with the pipe command error. Now the
3146 underlying error message should be appended to the second error message.

3153PH/03 The warning log line about a condition test deferring for a "warn" verb
3154 was being output only once per connection, rather than after each

3156 "warn" verbs). This seems wrong, so I have changed it.

3158TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3159 it should not have, which might have caused a crash in the right

3176PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3177 with the definition in sysexits.h (which is #included earlier).
3178 Fortunately, Exim does not actually use EX_OK. The code used to try to
3179 preserve the sysexits.h value, by assumimg that macro definitions were
3180 scanned for macro replacements. I have been disabused of this notion,
3181 so now the code just undefines EX_OK before #including unistd.h.

3183PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3184 in the smtp transport. When a block could not be written in a single
3185 write() function, the timeout was being re-applied to each part-write.
3186 This seems wrong - if the receiver was accepting one byte at a time it
3187 would take for ever. The timeout is now adjusted when this happens. It
3188 doesn't have to be particularly precise.

3257 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T

3261PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3262 the configuration file to be ":syslog", then the script "guesses" where
3263 the logs files are, rather than using the compiled in default. In our
3264 case the guess is not the same as the compiled default, so the script
3265 suddenly stopped working when I started to use syslog. The patch checks
3266 to see if log_file_path is "". If so, it attempts to read it from exim
3267 with no configuration file to get the compiled in version, before it
3268 falls back to the previous guessing code."

3318 picked up on a user's system that detects such things. There doesn't seem
3319 to be a gcc warning option for this - only an attribute that has to be
3320 put on the function's prototype. It seems that in Fedora Core 4 they have
3321 set this on a number of new functions. No doubt there will be more in due
3322 course.

3324PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3325 specify a transport. However, if an address that was verified by such a

3327 read the rcpt_include_affixes from the non-existent transport. Now it
3328 just assumes that the setting of that option is false. This bug was
