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

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

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

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

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

49JH/03 The smtp transport now requests PRDR by default, if the server offers
50 it.
51
01a4a5c5 52JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 53 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
54 can be used to disable this per-host. The build option
55 EXPERIMENTAL_CERTNAMES is withdrawn.
56
cb1d7830 57JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 58 default to the word "system" to access the system default CA bundle.

JH
59 For GnuTLS, only version 3.0.20 or later.
60
610ff438 61JH/06 Verification of the server certificate for a TLS connection is now tried

62 (but not required) by default. The verification status is now logged by
63 default, for both outbound TLS and client-certificate supplying inbound
64 TLS connections

69JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
70 Status Notification (bounce) messages are now MIME format per RFC 3464.
71 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
72 under the control of the dsn_advertise_hosts option, and routers may
73 have a dsn_lasthop option.

136JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
137 Normally benign, it bites when the pair was led to by a CNAME;
138 modern usage is to not canoicalize the domain to a CNAME target
139 (and we were inconsistent anyway for A-only vs AAAA+A).

162Exim version 4.85
163-----------------
164TL/01 When running the test suite, the README says that variables such as
165 no_msglog_check are global and can be placed anywhere in a specific
166 test's script, however it was observed that placement needed to be near
167 the beginning for it to behave that way. Changed the runtest perl
168 script to read through the entire script once to detect and set these
169 variables, reset to the beginning of the script, and then run through
170 the script parsing/test process like normal.

180TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
181 syntax errors in an expansion can be treated as a string instead of

183 instead of bool when processing it.

197JH/05 Fix results-pipe from transport process. Several recipients, combined
198 with certificate use, exposed issues where response data items split
199 over buffer boundaries were not parsed properly. This eventually
200 resulted in duplicates being sent. This issue only became common enough
201 to notice due to the introduction of conection certificate information,
202 the item size being so much larger. Found and fixed by Wolfgang Breyha.

212 is EXPERIMENTAL_EVENT, the main-configuration and transport options

aec45841 214 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533

215 routers, transports and related events. The tls:cert event is now also
216 raised for inbound connections, if the main configuration event_action
217 option is defined.

272-----------------
273
274TF/01 Correctly close the server side of TLS when forking for delivery.
275
276 When a message was received over SMTP with TLS, Exim failed to clear up
277 the incoming connection properly after forking off the child process to
278 deliver the message. In some situations the subsequent outgoing
279 delivery connection happened to have the same fd number as the incoming
280 connection previously had. Exim would try to use TLS and fail, logging
281 a "Bad file descriptor" error.

527TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
528
529 When a queue runner is handling a message, Exim first routes the
530 recipient addresses, during which it prunes them based on the retry
531 hints database. After that it attempts to deliver the message to
532 any remaining recipients. It then updates the hints database using
533 the retry rules.
534
535 So if a recipient address works intermittently, it can get repeatedly
536 deferred at routing time. The retry hints record remains fresh so the
537 address never reaches the final cutoff time.
538
539 This is a fairly common occurrence when a user is bumping up against
540 their storage quota. Exim had some logic in its local delivery code
541 to deal with this. However it did not apply to per-recipient defers
542 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
543
1ddeb334
TF
544 This change adds a proper retry rule check during routing so that the
545 final cutoff time is checked against the message's age. We only do
546 this check if there is an address retry record and there is not a
547 domain retry record; this implies that previous attempts to handle
548 the address had the retry_use_local_parts option turned on. We use
549 this as an approximation for the destination being like a local
550 delivery, as in LMTP.
67bd1ab3
TF
551
552 I suspect this new check makes the old local delivery cutoff check
553 redundant, but I have not verified this so I left the code in place.

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

588 Server implementation by Todd Lyons, client by JH.
589 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
590 config variable "prdr_enable" controls whether the server
591 advertises the facility. If the client requests PRDR a new
592 acl_data_smtp_prdr ACL is called once for each recipient, after
593 the body content is received and before the acl_smtp_data ACL.
594 The client is controlled by bolth of: a hosts_try_prdr option
595 on the smtp transport, and the server advertisement.
596 Default client logging of deliveries and rejections involving
597 PRDR are flagged with the string "PRDR".

875TF/03 Make the exiwhat support code safe for signals. Previously Exim might
876 lock up or crash if it happened to be inside a call to libc when it
877 got a SIGUSR1 from exiwhat.
878
879 The SIGUSR1 handler appends the current process status to the process
880 log which is later printed by exiwhat. It used to use the general
881 purpose logging code to do this, but several functions it calls are
882 not safe for signals.
883
884 The new output code in the SIGUSR1 handler is specific to the process
885 log, and simple enough that it's easy to inspect for signal safety.
886 Removing some special cases also simplifies the general logging code.
887 Removing the spurious timestamps from the process log simplifies
888 exiwhat.

890TF/04 Improved ratelimit ACL condition.
891
892 The /noupdate option has been deprecated in favour of /readonly which
893 has clearer semantics. The /leaky, /strict, and /readonly update modes
894 are mutually exclusive. The update mode is no longer included in the
895 database key; it just determines when the database is updated. (This
896 means that when you upgrde Exim will forget old rate measurements.)
897
898 Exim now checks that the per_* options are used with an update mode that
899 makes sense for the current ACL. For example, when Exim is processing a
900 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
901 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
902 must specify per_mail/readonly. If you omit the update mode it defaults to
903 /leaky where that makes sense (as before) or /readonly where required.
904
905 The /noupdate option is now undocumented but still supported for
906 backwards compatibility. It is equivalent to /readonly except that in
907 ACLs where /readonly is required you may specify /leaky/noupdate or
908 /strict/noupdate which are treated the same as /readonly.
909
910 A useful new feature is the /count= option. This is a generalization
911 of the per_byte option, so that you can measure the throughput of other
912 aggregate values. For example, the per_byte option is now equivalent
913 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
914
915 The per_rcpt option has been generalized using the /count= mechanism
916 (though it's more complicated than the per_byte equivalence). When it is
917 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
918 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
919 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
920 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
921 Note that using per_rcpt with a non-readonly update mode in more than
922 one ACL will cause the recipients to be double-counted. (The per_mail
923 and per_byte options don't have this problem.)
924
925 The handling of very low rates has changed slightly. If the computed rate
926 is less than the event's count (usually one) then this event is the first
927 after a long gap. In this case the rate is set to the same as this event's
928 count, so that the first message of a spam run is counted properly.
929
930 The major new feature is a mechanism for counting the rate of unique
931 events. The new per_addr option counts the number of different
932 recipients that someone has sent messages to in the last time period. It
933 behaves like per_rcpt if all the recipient addresses are different, but
934 duplicate recipient addresses do not increase the measured rate. Like
935 the /count= option this is a general mechanism, so the per_addr option
936 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
937 example, measure the rate that a client uses different sender addresses
938 with the options per_mail/unique=$sender_address. There are further
939 details in the main documentation.

1511PH/01 Another patch from the Sieve maintainer.
1512
6a3bceb1
PH
1513PH/02 When an IPv6 address is converted to a string for single-key lookup
1514 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1515 dots are used instead of colons so that keys in lsearch files need not
1516 contain colons. This was done some time before quoting was made available
1517 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1518 (notated using the quote facility) so as to distinguish them from IPv4
1519 keys. This meant that lookups for IP addresses in host lists did not work
1520 for iplsearch lookups.
1521
1522 This has been fixed by arranging for IPv6 addresses to be expressed with
1523 colons if the lookup type is iplsearch. This is not incompatible, because
1524 previously such lookups could never work.
1525
1526 The situation is now rather anomolous, since one *can* have colons in
1527 ordinary lsearch keys. However, making the change in all cases is
1528 incompatible and would probably break a number of configurations.

1533MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1534 conversion specification without a maximum field width, thereby enabling
1535 a rogue spamd server to cause a buffer overflow. While nobody in their
1536 right mind would setup Exim to query an untrusted spamd server, an
1537 attacker that gains access to a server running spamd could potentially
1538 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1543MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1544 a directory entry by the name of the lookup key. Previously, if a
1545 symlink pointed to a non-existing file or a file in a directory that
1546 Exim lacked permissions to read, a lookup for a key matching that
1547 symlink would fail. Now it is enough that a matching directory entry
1548 exists, symlink or not. (Bugzilla 503.)

PH
1731PH/29 SMTP synchronization checks are implemented when a command is read -
1732 there is a check that no more input is waiting when there shouldn't be
1733 any. However, for some commands, a delay in an ACL can mean that it is
1734 some time before the response is written. In this time, more input might
1735 arrive, invalidly. So now there are extra checks after an ACL has run for
1736 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1737 pipelining has not been advertised.

1752 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1753 was a macro that became an assignment, so it seemed to work. This has

1793 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1811 the response to the final '.' that terminates a message, but only in the
1812 case where the client has not sent further data following the '.'
1813 (unfortunately, this is allowed). However, in many cases there won't be
1814 any further data because there won't be any more messages to send. A call
1815 to select() can be used: if it shows that the input is "ready", there is
1816 either input waiting, or the socket has been closed. An attempt to read
1817 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1818 would have sent an OK response which the client would never have see.

1829PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1830 fixed by 4.65/MH/01 (is this a record?) are fixed:
1831
1832 (i) An empty string was always treated as zero by the numeric comparison
1833 operators. This behaviour has been restored.
1834
1835 (ii) It is documented that the numeric comparison operators always treat
1836 their arguments as decimal numbers. This was broken in that numbers
1837 starting with 0 were being interpreted as octal.
1838
1839 While fixing these problems I realized that there was another issue that
1840 hadn't been noticed. Values of message_size_limit (both the global option
1841 and the transport option) were treated as octal if they started with 0.
1842 The documentation was vague. These values are now always treated as
1843 decimal, and I will make that clear in the documentation.

1859 is held in a short int, deliveries were likely to be lost. As such a
1860 large number of recipients for a single message is ridiculous
1861 (performance will be very, very poor), I have chosen to impose a limit
1862 rather than extend the field.

2b1c6e3a
PH
1887PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1888 callout verification, Exim cached a "reject" for the entire domain. This
1889 is correct for most verifications, but it is not correct for a recipient
1890 verification with use_sender or use_postmaster set, because in that case
1891 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1892 case of MAIL FROM:<> rejection from other early rejections (e.g.
1893 rejection of HELO). When verifying a recipient using a non-null MAIL
1894 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1895 Whatever the result of the callout, the value of the domain cache is
1896 left unchanged (for any other kind of callout, getting as far as trying
1897 RCPT means that the domain itself is ok).

1933 probably the interface on which it is arriving) and not to the outgoing
1934 callout (which could be using a different interface). This has been
1935 changed to use the value of the helo_data option from the smtp transport
1936 instead - this is what is used when a message is actually being sent. If
1937 there is no remote transport (possible with a router that sets up host
1938 addresses), $smtp_active_hostname is used.

14aa5a05
PH
1942 (a) The code assumed that strncpy() returns a negative number on buffer
1943 overflow, which isn't the case. Replaced with Exim's string_format()
1944 function.
1945 (b) There were several signed/unsigned issues. I just did the minimum
1946 hacking in of casts. There is scope for a larger refactoring.
1947 (c) The code used strcasecmp() which is not a standard C function.
1948 Replaced with Exim's strcmpic() function.
1949 (d) The code set only $1; it now sets $auth1 as well.
1950 (e) A simple test gave the error "authentication client didn't specify
1951 service in request". It would seem that Dovecot has changed its
1952 interface. Fortunately there's a specification; I followed it and
1953 changed what the client sends and it appears to be working now.

1959 address A is aliased to B and C, where B exists and C does not. Without
1960 -v the output is "A verified" because verification stops after a
1961 successful redirection if more than one address is generated. However,
1962 with -v the child addresses are also verified. Exim was outputting "A
1963 failed to verify" and then showing the successful verification for C,
1964 with its parentage. It now outputs "B failed to verify", showing B's
1965 parentage before showing the successful verification of C.

PH
1971PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1972 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1973 they consult the DNS. I had assumed they would set it the way they
1974 wanted; and indeed my experiments on Linux seem to show that in some
1975 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1976 To be on the safe side, however, I have now made the interface to
1977 host_find_byname() similar to host_find_bydns(), with an argument
1978 containing the DNS resolver options. The host_find_byname() function now
1979 sets these options at its start, just as host_find_bydns() does. The smtp
1980 transport options dns_qualify_single and dns_search_parents are passed to
1981 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1982 of host_find_byname() use the default settings of RES_DEFNAMES
1983 (qualify_single) but not RES_DNSRCH (search_parents).

1985PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1986 spool_read_header() do less string testing, by means of a preliminary
1987 switch on the second character of optional "-foo" lines. (This is
1988 overdue, caused by the large number of possibilities that now exist.
1989 Originally there were few.) While I was there, I also converted the
1990 str(n)cmp tests so they don't re-test the leading "-" and the first
1991 character, in the hope this might squeeze out yet more improvement.

1993PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1994 flag allowing group syntax was set by the header_syntax check but not
1995 turned off, possible causing trouble later; (2) The flag was not being
1996 set at all for the header_verify test, causing "group"-style headers to
1997 be rejected. I have now set it in this case, and also caused header_
1998 verify to ignore an empty address taken from a group. While doing this, I
1999 came across some other cases where the code for allowing group syntax
2000 while scanning a header line wasn't quite right (mostly, not resetting
2001 the flag correctly in the right place). These bugs could have caused
2002 trouble for malformed header lines. I hope it is now all correct.

2010PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

2012 embargo. It requires special client support, and Exim is probably the
2013 only MTA that supported it -- and would never use it because real RSA is
2014 always available. This code has been removed, because it had the bad
2015 effect of slowing Exim down by computing (never used) parameters for the
2016 RSA_EXPORT functionality.

2055
2056PH/30 Exim was sometimes attempting to deliver messages that had suffered
2057 address errors (4xx response to RCPT) over the same connection as other
2058 messages routed to the same hosts. Such deliveries are always "forced",
2059 so retry times are not inspected. This resulted in far too many retries
2060 for the affected addresses. The effect occurred only when there were more
2061 hosts than the hosts_max_try setting in the smtp transport when it had
2062 the 4xx errors. Those hosts that it had tried were not added to the list
2063 of hosts for which the message was waiting, so if all were tried, there
2064 was no problem. Two fixes have been applied:
2065
2066 (i) If there are any address or message errors in an SMTP delivery, none
2067 of the hosts (tried or untried) are now added to the list of hosts
2068 for which the message is waiting, so the message should not be a
2069 candidate for sending over the same connection that was used for a
2070 successful delivery of some other message. This seems entirely
2071 reasonable: after all the message is NOT "waiting for some host".
2072 This is so "obvious" that I'm not sure why it wasn't done
2073 previously. Hope I haven't missed anything, but it can't do any
2074 harm, as the worst effect is to miss an optimization.
2075
2076 (ii) If, despite (i), such a delivery is accidentally attempted, the
2077 routing retry time is respected, so at least it doesn't keep
2078 hammering the server.

2093PH/35 The error "getsockname() failed: connection reset by peer" was being
2094 written to the panic log as well as the main log, but it isn't really

2096 removed the panic log writing for the ECONNRESET error when getsockname()
2097 fails.

48c7f9e2
PH
2099PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2100 runs only) independently of the message's sender address. This meant
2101 that, if the 4xx error was in fact related to the sender, a different
2102 message to the same recipient with a different sender could confuse
2103 things. In particualar, this can happen when sending to a greylisting
2104 server, but other circumstances could also provoke similar problems.
2105 I have changed the default so that the retry time for these errors is now
2106 based a combination of the sender and recipient addresses. This change
2107 can be overridden by setting address_retry_include_sender=false in the
2108 smtp transport.

2376PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2377 "Deny" causes Exim to reject the incoming connection with a 554 error.
2378 Unfortunately, if there is a major crisis, such as a disk failure,
2379 tcp-wrappers gives "deny", whereas what one would like would be some
2380 kind of temporary error. A kludge has been added to help with this.
2381 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2382 554 error is used if errno is still zero or contains ENOENT (which occurs
2383 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2384 451 error is used.

2409 used only to exclude .Trash (or whatever) when the size of the mailbox
2410 was calculated. There was no check that a delivery was happening into an

2420PH/01 The code for finding all the local interface addresses on a FreeBSD
2421 system running IPv6 was broken. This may well have applied to all BSD
2422 systems, as well as to others that have similar system calls. The broken
2423 code found IPv4 interfaces correctly, but gave incorrect values for the
2424 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2425 that it would not match correctly against @[] and not recognize the IPv6
2426 addresses as local.

2469 autoreply, Exim could try to deliver to a non-existent relative file

2492 (a) Failures to set uid/gid, the current directory, or a process leader
2493 in a subprocess such as that created by queryprogram now generate
2494 suitable debugging ouput when -d is set.

2504 additional section of a DNS packet that returns MX or SRV records.
2505 Instead, it always explicitly searches for A/AAAA records. This avoids
2506 major problems that occur when a DNS server includes only records of one
2507 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2508 fixed another bug: if SRV records were looked up and the corresponding
2509 address records were *not* found in the additional section, the port
2510 values from the SRV records were lost.

2512PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2520PH/19 When calculating a retry time, Exim used to measure the "time since
2521 failure" by looking at the "first failed" field in the retry record. Now
2522 it does not use this if it is later than than the arrival time of the
2523 message. Instead it uses the arrival time. This makes for better
2524 behaviour in cases where some deliveries succeed, thus re-setting the
2525 "first failed" field. An example is a quota failure for a huge message
2526 when small messages continue to be delivered. Without this change, the
2527 "time since failure" will always be short, possible causing more frequent
2528 delivery attempts for the huge message than are intended.

2625PH/42 The content-scanning code uses fopen() to create files in which to put
2626 message data. Previously it was not paying any attention to the mode of
2627 the files. Exim runs with umask(0) because the rest of the code creates
2628 files with open(), and sets the required mode explicitly. Thus, these
2629 files were ending up world-writeable. This was not a big issue, because,
2630 being within the spool directory, they were not world-accessible. I have
2631 created a function called modefopen, which takes an additional mode
2632 argument. It sets umask(777), creates the file, chmods it to the required
2633 mode, then resets the umask. All the relevant calls to fopen() in the

2674 was used in LMTP mode. This meant that they could be retried too
2675 frequently, and not timed out correctly.
2676
2677 (ii) Exim was setting the flag that allows error details to be returned
2678 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2679 recipients that were returned after the DATA command.
2680
2681PH/53 This is related to PH/52, but is more general: for any failing address,
2682 when detailed error information was permitted to be returned to the

2741PH/68 The bounce_return_message and bounce_return_body options were not being
2742 honoured for bounces generated during the reception of non-SMTP messages.
2743 In particular, this applied to messages rejected by the ACL. This bug has
2744 been fixed. However, if bounce_return_message is true and bounce_return_
2745 body is false, the headers that are returned for a non-SMTP message
2746 include only those that have been read before the error was detected.

2755PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2756 function verify_get_ident() calls ip_connect() to connect a socket, but
2757 if the "connect()" function timed out, ip_connect() used to close the
2758 socket. However, verify_get_ident() also closes the socket later, and in
2759 between Exim writes to the log, which may get opened at this point. When
2760 the socket was closed in ip_connect(), the log could get the same file
2761 descriptor number as the socket. This naturally causes chaos. The fix is
2762 not to close the socket in ip_connect(); the socket should be closed by
2763 the function that creates it. There was only one place in the code where
2764 this was missing, in the iplookup router, which I don't think anybody now
2765 uses, but I've fixed it anyway.

2788
2789 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2790 string.
2791
2792 (3) Reset the variables that are obtained from the first argument of
2793 ${prvscheck and used in the second argument before leaving the code,
2794 because their memory is reclaimed, so using them afterwards may do
2795 silly things.
2796
2797 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2798 one (it's much easier than Tom thought :-).
2799
2800 (5) Because of (4), we can now allow for the use of $prvscheck_result
2801 inside the third argument.

2816 may be more than one such address. If so, they are comma-separated, like

2821PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2822 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2823 not being looked up in the rDNS to get a host name, Exim was showing the
2824 IP address twice in Received: lines, even though the IP addresses were
2825 identical. For example:
2826
2827 Received: from [1.2.3.4] (helo=[1.2.3.4])
2828
2829 However, if the real host name was known, it was omitting the HELO data
2830 if it matched the actual IP address. This has been tidied up so that it
2831 doesn't show the same IP address twice.

2857PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2859
2860 Auto-submitted: auto-generated
2861
2862 in the messages that it generates (bounce messages and others, such as
2863 warnings). In the case of bounce messages for non-SMTP mesages, there was
2864 also a typo: it was using "Auto_submitted" (underscore instead of
2865 hyphen). Since every message generated by Exim is necessarily in response
2866 to another message, thes have all been changed to:
2867
2868 Auto-Submitted: auto-replied
2869
2870 in accordance with these statements in the RFC:
2871
2872 The auto-replied keyword:
2873
2874 - SHOULD be used on messages sent in direct response to another
2875 message by an automatic process,
2876
2877 - MUST NOT be used on manually-generated messages,

2880 Disposition Notifications (MDNs),

2920PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2921 canonical form (as documented). However, after a host name lookup from
2922 the IP address, check_host() was doing a simple string comparison with
2923 addresses acquired from the DNS when checking that the found name did
2924 have the original IP as one of its addresses. Since any found IPv6
2925 addresses are likely to be in abbreviated form, the comparison could
2926 fail. Luckily, there already exists a function for doing the comparison
2927 by converting both addresses to binary, so now that is used instead of
2928 the text comparison.

3145PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
3146 avoiding the need to install special zones in a real server. This is
3147 backwards compatible; if it can't find the fake resolver, it drops back.
3148 Thus, both old and new test suites can be run.

3202PH/03 The warning log line about a condition test deferring for a "warn" verb

PH
3225PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3226 with the definition in sysexits.h (which is #included earlier).
3227 Fortunately, Exim does not actually use EX_OK. The code used to try to
3228 preserve the sysexits.h value, by assumimg that macro definitions were
3229 scanned for macro replacements. I have been disabused of this notion,
3230 so now the code just undefines EX_OK before #including unistd.h.

PH
3232PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3233 in the smtp transport. When a block could not be written in a single
3234 write() function, the timeout was being re-applied to each part-write.
3235 This seems wrong - if the receiver was accepting one byte at a time it
3236 would take for ever. The timeout is now adjusted when this happens. It
3237 doesn't have to be particularly precise.

3269 obviously out-of-the-box. Patch from Alex Miller.

3303PH/15 The code I had for printing potentially long long variables in PH/11

3306 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3307 to be "long long int" or "long int". This is needed for the internal
3308 formatting function string_vformat().

3310PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3311 the configuration file to be ":syslog", then the script "guesses" where
3312 the logs files are, rather than using the compiled in default. In our
3313 case the guess is not the same as the compiled default, so the script
3314 suddenly stopped working when I started to use syslog. The patch checks
3315 to see if log_file_path is "". If so, it attempts to read it from exim
3316 with no configuration file to get the compiled in version, before it
3317 falls back to the previous guessing code."

3331PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3332 patch removes a few documentation additions to RFC 3028, because the
