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
ac881e27
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.

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.

66 it.
67
01a4a5c5 68JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 69 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
70 can be used to disable this per-host. The build option
71 EXPERIMENTAL_CERTNAMES is withdrawn.
72
cb1d7830 73JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 74 default to the word "system" to access the system default CA bundle.
cb1d7830
JH
75 For GnuTLS, only version 3.0.20 or later.
76
610ff438 77JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
78 (but not required) by default. The verification status is now logged by
79 default, for both outbound TLS and client-certificate supplying inbound
80 TLS connections
610ff438 81

82JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
83 sites use this now.
84
50dc7409
JH
85JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
86 Status Notification (bounce) messages are now MIME format per RFC 3464.
87 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
88 under the control of the dsn_advertise_hosts option, and routers may
89 have a dsn_lasthop option.

152JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
153 Normally benign, it bites when the pair was led to by a CNAME;
154 modern usage is to not canoicalize the domain to a CNAME target
155 (and we were inconsistent anyway for A-only vs AAAA+A).

178Exim version 4.85
179-----------------
180TL/01 When running the test suite, the README says that variables such as
181 no_msglog_check are global and can be placed anywhere in a specific
182 test's script, however it was observed that placement needed to be near
183 the beginning for it to behave that way. Changed the runtest perl
184 script to read through the entire script once to detect and set these
185 variables, reset to the beginning of the script, and then run through
186 the script parsing/test process like normal.

WB
213JH/05 Fix results-pipe from transport process. Several recipients, combined
214 with certificate use, exposed issues where response data items split
215 over buffer boundaries were not parsed properly. This eventually
216 resulted in duplicates being sent. This issue only became common enough
217 to notice due to the introduction of conection certificate information,
218 the item size being so much larger. Found and fixed by Wolfgang Breyha.

aec45841 230 and $event_defer_errno. There is a new variable $verify_mode, usable in

290TF/01 Correctly close the server side of TLS when forking for delivery.
291
292 When a message was received over SMTP with TLS, Exim failed to clear up
293 the incoming connection properly after forking off the child process to
294 deliver the message. In some situations the subsequent outgoing
295 delivery connection happened to have the same fd number as the incoming
296 connection previously had. Exim would try to use TLS and fail, logging
297 a "Bad file descriptor" error.

543TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
544
545 When a queue runner is handling a message, Exim first routes the
546 recipient addresses, during which it prunes them based on the retry
547 hints database. After that it attempts to deliver the message to
548 any remaining recipients. It then updates the hints database using
549 the retry rules.
550
551 So if a recipient address works intermittently, it can get repeatedly
552 deferred at routing time. The retry hints record remains fresh so the
553 address never reaches the final cutoff time.
554
555 This is a fairly common occurrence when a user is bumping up against
556 their storage quota. Exim had some logic in its local delivery code
557 to deal with this. However it did not apply to per-recipient defers
558 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
559
1ddeb334
TF
560 This change adds a proper retry rule check during routing so that the
561 final cutoff time is checked against the message's age. We only do
562 this check if there is an address retry record and there is not a
563 domain retry record; this implies that previous attempts to handle
564 the address had the retry_use_local_parts option turned on. We use
565 this as an approximation for the destination being like a local
566 delivery, as in LMTP.
67bd1ab3
TF
567
568 I suspect this new check makes the old local delivery cutoff check
569 redundant, but I have not verified this so I left the code in place.

578 the header to contain my full name, whereas it should have added
579 a Resent-Sender: header. It erroneously treats any prefix of the
580 username as equal to the username.

604 Server implementation by Todd Lyons, client by JH.
605 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
606 config variable "prdr_enable" controls whether the server
607 advertises the facility. If the client requests PRDR a new
608 acl_data_smtp_prdr ACL is called once for each recipient, after
609 the body content is received and before the acl_smtp_data ACL.
610 The client is controlled by bolth of: a hosts_try_prdr option
611 on the smtp transport, and the server advertisement.
612 Default client logging of deliveries and rejections involving
613 PRDR are flagged with the string "PRDR".

891TF/03 Make the exiwhat support code safe for signals. Previously Exim might
892 lock up or crash if it happened to be inside a call to libc when it
893 got a SIGUSR1 from exiwhat.
894
895 The SIGUSR1 handler appends the current process status to the process
896 log which is later printed by exiwhat. It used to use the general
897 purpose logging code to do this, but several functions it calls are
898 not safe for signals.
899
900 The new output code in the SIGUSR1 handler is specific to the process
901 log, and simple enough that it's easy to inspect for signal safety.
902 Removing some special cases also simplifies the general logging code.
903 Removing the spurious timestamps from the process log simplifies
904 exiwhat.
905
c99ce5c9
TF
906TF/04 Improved ratelimit ACL condition.
907
908 The /noupdate option has been deprecated in favour of /readonly which
909 has clearer semantics. The /leaky, /strict, and /readonly update modes
910 are mutually exclusive. The update mode is no longer included in the
911 database key; it just determines when the database is updated. (This
912 means that when you upgrde Exim will forget old rate measurements.)
913
914 Exim now checks that the per_* options are used with an update mode that
915 makes sense for the current ACL. For example, when Exim is processing a
916 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
917 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
918 must specify per_mail/readonly. If you omit the update mode it defaults to
919 /leaky where that makes sense (as before) or /readonly where required.
920
921 The /noupdate option is now undocumented but still supported for
922 backwards compatibility. It is equivalent to /readonly except that in
923 ACLs where /readonly is required you may specify /leaky/noupdate or
924 /strict/noupdate which are treated the same as /readonly.
925
926 A useful new feature is the /count= option. This is a generalization
927 of the per_byte option, so that you can measure the throughput of other
928 aggregate values. For example, the per_byte option is now equivalent
929 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
930
931 The per_rcpt option has been generalized using the /count= mechanism
932 (though it's more complicated than the per_byte equivalence). When it is
933 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
934 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
935 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
936 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
937 Note that using per_rcpt with a non-readonly update mode in more than
938 one ACL will cause the recipients to be double-counted. (The per_mail
939 and per_byte options don't have this problem.)
940
941 The handling of very low rates has changed slightly. If the computed rate
942 is less than the event's count (usually one) then this event is the first
943 after a long gap. In this case the rate is set to the same as this event's
944 count, so that the first message of a spam run is counted properly.
945
946 The major new feature is a mechanism for counting the rate of unique
947 events. The new per_addr option counts the number of different
948 recipients that someone has sent messages to in the last time period. It
949 behaves like per_rcpt if all the recipient addresses are different, but
950 duplicate recipient addresses do not increase the measured rate. Like
951 the /count= option this is a general mechanism, so the per_addr option
952 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
953 example, measure the rate that a client uses different sender addresses
954 with the options per_mail/unique=$sender_address. There are further
955 details in the main documentation.

1527PH/01 Another patch from the Sieve maintainer.
1528
6a3bceb1
PH
1529PH/02 When an IPv6 address is converted to a string for single-key lookup
1530 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1531 dots are used instead of colons so that keys in lsearch files need not
1532 contain colons. This was done some time before quoting was made available
1533 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1534 (notated using the quote facility) so as to distinguish them from IPv4
1535 keys. This meant that lookups for IP addresses in host lists did not work
1536 for iplsearch lookups.
1537
1538 This has been fixed by arranging for IPv6 addresses to be expressed with
1539 colons if the lookup type is iplsearch. This is not incompatible, because
1540 previously such lookups could never work.
1541
1542 The situation is now rather anomolous, since one *can* have colons in
1543 ordinary lsearch keys. However, making the change in all cases is
1544 incompatible and would probably break a number of configurations.

1549MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1550 conversion specification without a maximum field width, thereby enabling
1551 a rogue spamd server to cause a buffer overflow. While nobody in their
1552 right mind would setup Exim to query an untrusted spamd server, an
1553 attacker that gains access to a server running spamd could potentially
1554 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1559MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1560 a directory entry by the name of the lookup key. Previously, if a
1561 symlink pointed to a non-existing file or a file in a directory that
1562 Exim lacked permissions to read, a lookup for a key matching that
1563 symlink would fail. Now it is enough that a matching directory entry
1564 exists, symlink or not. (Bugzilla 503.)

1747PH/29 SMTP synchronization checks are implemented when a command is read -
1748 there is a check that no more input is waiting when there shouldn't be

1750 some time before the response is written. In this time, more input might
1751 arrive, invalidly. So now there are extra checks after an ACL has run for
1752 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1753 pipelining has not been advertised.

1768 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1769 was a macro that became an assignment, so it seemed to work. This has

1809 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1827 the response to the final '.' that terminates a message, but only in the
1828 case where the client has not sent further data following the '.'
1829 (unfortunately, this is allowed). However, in many cases there won't be
1830 any further data because there won't be any more messages to send. A call
1831 to select() can be used: if it shows that the input is "ready", there is
1832 either input waiting, or the socket has been closed. An attempt to read
1833 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1834 would have sent an OK response which the client would never have see.

1845PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1846 fixed by 4.65/MH/01 (is this a record?) are fixed:
1847
1848 (i) An empty string was always treated as zero by the numeric comparison
1849 operators. This behaviour has been restored.
1850
1851 (ii) It is documented that the numeric comparison operators always treat
1852 their arguments as decimal numbers. This was broken in that numbers
1853 starting with 0 were being interpreted as octal.
1854
1855 While fixing these problems I realized that there was another issue that
1856 hadn't been noticed. Values of message_size_limit (both the global option
1857 and the transport option) were treated as octal if they started with 0.
1858 The documentation was vague. These values are now always treated as
1859 decimal, and I will make that clear in the documentation.

1876 large number of recipients for a single message is ridiculous

2b1c6e3a
PH
1903PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1904 callout verification, Exim cached a "reject" for the entire domain. This
1905 is correct for most verifications, but it is not correct for a recipient
1906 verification with use_sender or use_postmaster set, because in that case
1907 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1908 case of MAIL FROM:<> rejection from other early rejections (e.g.
1909 rejection of HELO). When verifying a recipient using a non-null MAIL
1910 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1911 Whatever the result of the callout, the value of the domain cache is
1912 left unchanged (for any other kind of callout, getting as far as trying
1913 RCPT means that the domain itself is ok).

1950 callout (which could be using a different interface). This has been
1951 changed to use the value of the helo_data option from the smtp transport
1952 instead - this is what is used when a message is actually being sent. If
1953 there is no remote transport (possible with a router that sets up host

1960 function.
1961 (b) There were several signed/unsigned issues. I just did the minimum
1962 hacking in of casts. There is scope for a larger refactoring.
1963 (c) The code used strcasecmp() which is not a standard C function.
1964 Replaced with Exim's strcmpic() function.
1965 (d) The code set only $1; it now sets $auth1 as well.
1966 (e) A simple test gave the error "authentication client didn't specify
1967 service in request". It would seem that Dovecot has changed its
1968 interface. Fortunately there's a specification; I followed it and
1969 changed what the client sends and it appears to be working now.

1974PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1975 address A is aliased to B and C, where B exists and C does not. Without
1976 -v the output is "A verified" because verification stops after a
1977 successful redirection if more than one address is generated. However,
1978 with -v the child addresses are also verified. Exim was outputting "A
1979 failed to verify" and then showing the successful verification for C,
1980 with its parentage. It now outputs "B failed to verify", showing B's
1981 parentage before showing the successful verification of C.

PH
1987PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1988 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1989 they consult the DNS. I had assumed they would set it the way they
1990 wanted; and indeed my experiments on Linux seem to show that in some
1991 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1992 To be on the safe side, however, I have now made the interface to
1993 host_find_byname() similar to host_find_bydns(), with an argument
1994 containing the DNS resolver options. The host_find_byname() function now
1995 sets these options at its start, just as host_find_bydns() does. The smtp
1996 transport options dns_qualify_single and dns_search_parents are passed to
1997 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1998 of host_find_byname() use the default settings of RES_DEFNAMES
1999 (qualify_single) but not RES_DNSRCH (search_parents).

2002 spool_read_header() do less string testing, by means of a preliminary
2003 switch on the second character of optional "-foo" lines. (This is
2004 overdue, caused by the large number of possibilities that now exist.
2005 Originally there were few.) While I was there, I also converted the
2006 str(n)cmp tests so they don't re-test the leading "-" and the first
2007 character, in the hope this might squeeze out yet more improvement.

2009PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2010 flag allowing group syntax was set by the header_syntax check but not
2011 turned off, possible causing trouble later; (2) The flag was not being
2012 set at all for the header_verify test, causing "group"-style headers to
2013 be rejected. I have now set it in this case, and also caused header_
2014 verify to ignore an empty address taken from a group. While doing this, I
2015 came across some other cases where the code for allowing group syntax
2016 while scanning a header line wasn't quite right (mostly, not resetting
2017 the flag correctly in the right place). These bugs could have caused
2018 trouble for malformed header lines. I hope it is now all correct.

2026PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

2028 embargo. It requires special client support, and Exim is probably the
2029 only MTA that supported it -- and would never use it because real RSA is
2030 always available. This code has been removed, because it had the bad
2031 effect of slowing Exim down by computing (never used) parameters for the
2032 RSA_EXPORT functionality.

2071
2072PH/30 Exim was sometimes attempting to deliver messages that had suffered
2073 address errors (4xx response to RCPT) over the same connection as other
2074 messages routed to the same hosts. Such deliveries are always "forced",
2075 so retry times are not inspected. This resulted in far too many retries
2076 for the affected addresses. The effect occurred only when there were more
2077 hosts than the hosts_max_try setting in the smtp transport when it had
2078 the 4xx errors. Those hosts that it had tried were not added to the list
2079 of hosts for which the message was waiting, so if all were tried, there
2080 was no problem. Two fixes have been applied:
2081
2082 (i) If there are any address or message errors in an SMTP delivery, none
2083 of the hosts (tried or untried) are now added to the list of hosts
2084 for which the message is waiting, so the message should not be a
2085 candidate for sending over the same connection that was used for a
2086 successful delivery of some other message. This seems entirely
2087 reasonable: after all the message is NOT "waiting for some host".
2088 This is so "obvious" that I'm not sure why it wasn't done
2089 previously. Hope I haven't missed anything, but it can't do any
2090 harm, as the worst effect is to miss an optimization.
2091
2092 (ii) If, despite (i), such a delivery is accidentally attempted, the
2093 routing retry time is respected, so at least it doesn't keep
2094 hammering the server.

2109PH/35 The error "getsockname() failed: connection reset by peer" was being
2110 written to the panic log as well as the main log, but it isn't really

2112 removed the panic log writing for the ECONNRESET error when getsockname()
2113 fails.
2114
48c7f9e2
PH
2115PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2116 runs only) independently of the message's sender address. This meant
2117 that, if the 4xx error was in fact related to the sender, a different
2118 message to the same recipient with a different sender could confuse
2119 things. In particualar, this can happen when sending to a greylisting
2120 server, but other circumstances could also provoke similar problems.
2121 I have changed the default so that the retry time for these errors is now
2122 based a combination of the sender and recipient addresses. This change
2123 can be overridden by setting address_retry_include_sender=false in the
2124 smtp transport.

2392PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2394 Unfortunately, if there is a major crisis, such as a disk failure,
2395 tcp-wrappers gives "deny", whereas what one would like would be some
2396 kind of temporary error. A kludge has been added to help with this.
2397 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2398 554 error is used if errno is still zero or contains ENOENT (which occurs
2399 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2400 451 error is used.

2436PH/01 The code for finding all the local interface addresses on a FreeBSD
2437 system running IPv6 was broken. This may well have applied to all BSD
2438 systems, as well as to others that have similar system calls. The broken
2439 code found IPv4 interfaces correctly, but gave incorrect values for the
2440 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2441 that it would not match correctly against @[] and not recognize the IPv6
2442 addresses as local.

2485 autoreply, Exim could try to deliver to a non-existent relative file

2521 Instead, it always explicitly searches for A/AAAA records. This avoids
2522 major problems that occur when a DNS server includes only records of one
2523 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2524 fixed another bug: if SRV records were looked up and the corresponding
2525 address records were *not* found in the additional section, the port
2526 values from the SRV records were lost.

2536PH/19 When calculating a retry time, Exim used to measure the "time since
2537 failure" by looking at the "first failed" field in the retry record. Now
2538 it does not use this if it is later than than the arrival time of the
2539 message. Instead it uses the arrival time. This makes for better
2540 behaviour in cases where some deliveries succeed, thus re-setting the
2541 "first failed" field. An example is a quota failure for a huge message
2542 when small messages continue to be delivered. Without this change, the
2543 "time since failure" will always be short, possible causing more frequent
2544 delivery attempts for the huge message than are intended.

2641PH/42 The content-scanning code uses fopen() to create files in which to put

2644 files with open(), and sets the required mode explicitly. Thus, these
2645 files were ending up world-writeable. This was not a big issue, because,
2646 being within the spool directory, they were not world-accessible. I have
2647 created a function called modefopen, which takes an additional mode
2648 argument. It sets umask(777), creates the file, chmods it to the required
2649 mode, then resets the umask. All the relevant calls to fopen() in the

2690 was used in LMTP mode. This meant that they could be retried too
2691 frequently, and not timed out correctly.
2692
2693 (ii) Exim was setting the flag that allows error details to be returned
2694 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2695 recipients that were returned after the DATA command.
2696
2697PH/53 This is related to PH/52, but is more general: for any failing address,
2698 when detailed error information was permitted to be returned to the

2760 been fixed. However, if bounce_return_message is true and bounce_return_
2761 body is false, the headers that are returned for a non-SMTP message

2771PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2772 function verify_get_ident() calls ip_connect() to connect a socket, but
2773 if the "connect()" function timed out, ip_connect() used to close the
2774 socket. However, verify_get_ident() also closes the socket later, and in
2775 between Exim writes to the log, which may get opened at this point. When
2776 the socket was closed in ip_connect(), the log could get the same file
2777 descriptor number as the socket. This naturally causes chaos. The fix is
2778 not to close the socket in ip_connect(); the socket should be closed by
2779 the function that creates it. There was only one place in the code where
2780 this was missing, in the iplookup router, which I don't think anybody now
2781 uses, but I've fixed it anyway.

2804
2805 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2806 string.
2807
2808 (3) Reset the variables that are obtained from the first argument of
2809 ${prvscheck and used in the second argument before leaving the code,
2810 because their memory is reclaimed, so using them afterwards may do
2811 silly things.
2812
2813 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2814 one (it's much easier than Tom thought :-).
2815

2837PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2838 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2839 not being looked up in the rDNS to get a host name, Exim was showing the
2840 IP address twice in Received: lines, even though the IP addresses were
2841 identical. For example:
2842
2843 Received: from [1.2.3.4] (helo=[1.2.3.4])
2844
2845 However, if the real host name was known, it was omitting the HELO data
2846 if it matched the actual IP address. This has been tidied up so that it
2847 doesn't show the same IP address twice.

2875
2876 Auto-submitted: auto-generated
2877
2878 in the messages that it generates (bounce messages and others, such as
2879 warnings). In the case of bounce messages for non-SMTP mesages, there was
2880 also a typo: it was using "Auto_submitted" (underscore instead of
2881 hyphen). Since every message generated by Exim is necessarily in response
2882 to another message, thes have all been changed to:
2883
2884 Auto-Submitted: auto-replied
2885
2886 in accordance with these statements in the RFC:
2887
2888 The auto-replied keyword:
2889
2890 - SHOULD be used on messages sent in direct response to another
2891 message by an automatic process,

2936PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2938 the IP address, check_host() was doing a simple string comparison with
2939 addresses acquired from the DNS when checking that the found name did
2940 have the original IP as one of its addresses. Since any found IPv6
2941 addresses are likely to be in abbreviated form, the comparison could
2942 fail. Luckily, there already exists a function for doing the comparison
2943 by converting both addresses to binary, so now that is used instead of
2944 the text comparison.

2946PH/20 There was another similar case to PH/19, when a complete host name was

3218PH/03 The warning log line about a condition test deferring for a "warn" verb

PH
3241PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3242 with the definition in sysexits.h (which is #included earlier).
3243 Fortunately, Exim does not actually use EX_OK. The code used to try to
3244 preserve the sysexits.h value, by assumimg that macro definitions were
3245 scanned for macro replacements. I have been disabused of this notion,
3246 so now the code just undefines EX_OK before #including unistd.h.

3248PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3249 in the smtp transport. When a block could not be written in a single
3250 write() function, the timeout was being re-applied to each part-write.
3251 This seems wrong - if the receiver was accepting one byte at a time it
3252 would take for ever. The timeout is now adjusted when this happens. It
3253 doesn't have to be particularly precise.

3326PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3327 the configuration file to be ":syslog", then the script "guesses" where
3328 the logs files are, rather than using the compiled in default. In our
3329 case the guess is not the same as the compiled default, so the script
3330 suddenly stopped working when I started to use syslog. The patch checks
3331 to see if log_file_path is "". If so, it attempts to read it from exim
3332 with no configuration file to get the compiled in version, before it
3333 falls back to the previous guessing code."
