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.

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

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.

39 to HELO, local diagnostic string.

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.

JH
52JH/07 Bug 1678: Always record an interface option value, if set, as part of a

55 distinct.

80 it.
81
01a4a5c5 82JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 83 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
84 can be used to disable this per-host. The build option
85 EXPERIMENTAL_CERTNAMES is withdrawn.

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

192Exim version 4.85
193-----------------
194TL/01 When running the test suite, the README says that variables such as
195 no_msglog_check are global and can be placed anywhere in a specific
196 test's script, however it was observed that placement needed to be near
197 the beginning for it to behave that way. Changed the runtest perl
198 script to read through the entire script once to detect and set these
199 variables, reset to the beginning of the script, and then run through
200 the script parsing/test process like normal.

227JH/05 Fix results-pipe from transport process. Several recipients, combined
228 with certificate use, exposed issues where response data items split
229 over buffer boundaries were not parsed properly. This eventually
230 resulted in duplicates being sent. This issue only became common enough
231 to notice due to the introduction of conection certificate information,
232 the item size being so much larger. Found and fixed by Wolfgang Breyha.

305
306 When a message was received over SMTP with TLS, Exim failed to clear up
307 the incoming connection properly after forking off the child process to
308 deliver the message. In some situations the subsequent outgoing
309 delivery connection happened to have the same fd number as the incoming
310 connection previously had. Exim would try to use TLS and fail, logging

557TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
558
559 When a queue runner is handling a message, Exim first routes the
560 recipient addresses, during which it prunes them based on the retry
561 hints database. After that it attempts to deliver the message to
562 any remaining recipients. It then updates the hints database using
563 the retry rules.
564
565 So if a recipient address works intermittently, it can get repeatedly
566 deferred at routing time. The retry hints record remains fresh so the
567 address never reaches the final cutoff time.
568
569 This is a fairly common occurrence when a user is bumping up against
570 their storage quota. Exim had some logic in its local delivery code
571 to deal with this. However it did not apply to per-recipient defers
572 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
573
1ddeb334
TF
574 This change adds a proper retry rule check during routing so that the
575 final cutoff time is checked against the message's age. We only do
576 this check if there is an address retry record and there is not a
577 domain retry record; this implies that previous attempts to handle
578 the address had the retry_use_local_parts option turned on. We use
579 this as an approximation for the destination being like a local
580 delivery, as in LMTP.
67bd1ab3
TF
581
582 I suspect this new check makes the old local delivery cutoff check
583 redundant, but I have not verified this so I left the code in place.

587 Test 0254 submits a message to Exim with the header

590
591 When I ran the test suite under the user fanf2, Exim expanded
592 the header to contain my full name, whereas it should have added
593 a Resent-Sender: header. It erroneously treats any prefix of the
594 username as equal to the username.

596 This change corrects that bug.

618 Server implementation by Todd Lyons, client by JH.
619 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
620 config variable "prdr_enable" controls whether the server
621 advertises the facility. If the client requests PRDR a new
622 acl_data_smtp_prdr ACL is called once for each recipient, after
623 the body content is received and before the acl_smtp_data ACL.
624 The client is controlled by bolth of: a hosts_try_prdr option
625 on the smtp transport, and the server advertisement.
626 Default client logging of deliveries and rejections involving
627 PRDR are flagged with the string "PRDR".

905TF/03 Make the exiwhat support code safe for signals. Previously Exim might
906 lock up or crash if it happened to be inside a call to libc when it
907 got a SIGUSR1 from exiwhat.
908
909 The SIGUSR1 handler appends the current process status to the process
910 log which is later printed by exiwhat. It used to use the general
911 purpose logging code to do this, but several functions it calls are
912 not safe for signals.
913
914 The new output code in the SIGUSR1 handler is specific to the process
915 log, and simple enough that it's easy to inspect for signal safety.
916 Removing some special cases also simplifies the general logging code.
917 Removing the spurious timestamps from the process log simplifies
918 exiwhat.

TF
920TF/04 Improved ratelimit ACL condition.
921
922 The /noupdate option has been deprecated in favour of /readonly which
923 has clearer semantics. The /leaky, /strict, and /readonly update modes
924 are mutually exclusive. The update mode is no longer included in the
925 database key; it just determines when the database is updated. (This
926 means that when you upgrde Exim will forget old rate measurements.)
927
928 Exim now checks that the per_* options are used with an update mode that
929 makes sense for the current ACL. For example, when Exim is processing a
930 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
931 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
932 must specify per_mail/readonly. If you omit the update mode it defaults to
933 /leaky where that makes sense (as before) or /readonly where required.
934
935 The /noupdate option is now undocumented but still supported for
936 backwards compatibility. It is equivalent to /readonly except that in
937 ACLs where /readonly is required you may specify /leaky/noupdate or
938 /strict/noupdate which are treated the same as /readonly.
939
940 A useful new feature is the /count= option. This is a generalization
941 of the per_byte option, so that you can measure the throughput of other
942 aggregate values. For example, the per_byte option is now equivalent
943 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
944
945 The per_rcpt option has been generalized using the /count= mechanism
946 (though it's more complicated than the per_byte equivalence). When it is
947 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
948 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
949 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
950 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
951 Note that using per_rcpt with a non-readonly update mode in more than
952 one ACL will cause the recipients to be double-counted. (The per_mail
953 and per_byte options don't have this problem.)
954
955 The handling of very low rates has changed slightly. If the computed rate
956 is less than the event's count (usually one) then this event is the first
957 after a long gap. In this case the rate is set to the same as this event's
958 count, so that the first message of a spam run is counted properly.
959
960 The major new feature is a mechanism for counting the rate of unique
961 events. The new per_addr option counts the number of different
962 recipients that someone has sent messages to in the last time period. It
963 behaves like per_rcpt if all the recipient addresses are different, but
964 duplicate recipient addresses do not increase the measured rate. Like
965 the /count= option this is a general mechanism, so the per_addr option
966 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
967 example, measure the rate that a client uses different sender addresses
968 with the options per_mail/unique=$sender_address. There are further
969 details in the main documentation.

1541PH/01 Another patch from the Sieve maintainer.
1542
6a3bceb1
PH
1543PH/02 When an IPv6 address is converted to a string for single-key lookup
1544 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1545 dots are used instead of colons so that keys in lsearch files need not
1546 contain colons. This was done some time before quoting was made available
1547 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1548 (notated using the quote facility) so as to distinguish them from IPv4
1549 keys. This meant that lookups for IP addresses in host lists did not work
1550 for iplsearch lookups.
1551
1552 This has been fixed by arranging for IPv6 addresses to be expressed with
1553 colons if the lookup type is iplsearch. This is not incompatible, because
1554 previously such lookups could never work.
1555
1556 The situation is now rather anomolous, since one *can* have colons in
1557 ordinary lsearch keys. However, making the change in all cases is
1558 incompatible and would probably break a number of configurations.

1563MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1564 conversion specification without a maximum field width, thereby enabling
1565 a rogue spamd server to cause a buffer overflow. While nobody in their
1566 right mind would setup Exim to query an untrusted spamd server, an
1567 attacker that gains access to a server running spamd could potentially
1568 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1573MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1574 a directory entry by the name of the lookup key. Previously, if a
1575 symlink pointed to a non-existing file or a file in a directory that
1576 Exim lacked permissions to read, a lookup for a key matching that
1577 symlink would fail. Now it is enough that a matching directory entry
1578 exists, symlink or not. (Bugzilla 503.)

PH
1761PH/29 SMTP synchronization checks are implemented when a command is read -
1762 there is a check that no more input is waiting when there shouldn't be
1763 any. However, for some commands, a delay in an ACL can mean that it is
1764 some time before the response is written. In this time, more input might
1765 arrive, invalidly. So now there are extra checks after an ACL has run for
1766 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1767 pipelining has not been advertised.

1782 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1783 was a macro that became an assignment, so it seemed to work. This has
1784 changed to a proper function call with a void return, hence the compile
1785 error. Exim's code has been fixed.

1813PH/40 When Exim receives a message, it writes the login name, uid, and gid of

1815 behaving confusingly. When first started, it used values for whoever
1816 started the daemon, but after a SIGHUP it used the Exim user (because it
1817 calls itself on a restart). I have changed the code so that it now always
1818 uses the Exim user.

1823 with PIPELINING or a stupid MUA), the error message that was given to the
1824 RCPT commands is included in the rejection of the DATA command. This is

PH
1841 the response to the final '.' that terminates a message, but only in the
1842 case where the client has not sent further data following the '.'
1843 (unfortunately, this is allowed). However, in many cases there won't be
1844 any further data because there won't be any more messages to send. A call
1845 to select() can be used: if it shows that the input is "ready", there is
1846 either input waiting, or the socket has been closed. An attempt to read
1847 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1848 would have sent an OK response which the client would never have see.

1859PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1860 fixed by 4.65/MH/01 (is this a record?) are fixed:
1861
1862 (i) An empty string was always treated as zero by the numeric comparison
1863 operators. This behaviour has been restored.
1864
1865 (ii) It is documented that the numeric comparison operators always treat
1866 their arguments as decimal numbers. This was broken in that numbers
1867 starting with 0 were being interpreted as octal.
1868
1869 While fixing these problems I realized that there was another issue that
1870 hadn't been noticed. Values of message_size_limit (both the global option
1871 and the transport option) were treated as octal if they started with 0.
1872 The documentation was vague. These values are now always treated as
1873 decimal, and I will make that clear in the documentation.

1890 large number of recipients for a single message is ridiculous

2b1c6e3a
PH
1917PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1918 callout verification, Exim cached a "reject" for the entire domain. This
1919 is correct for most verifications, but it is not correct for a recipient
1920 verification with use_sender or use_postmaster set, because in that case
1921 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1922 case of MAIL FROM:<> rejection from other early rejections (e.g.
1923 rejection of HELO). When verifying a recipient using a non-null MAIL
1924 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1925 Whatever the result of the callout, the value of the domain cache is
1926 left unchanged (for any other kind of callout, getting as far as trying
1927 RCPT means that the domain itself is ok).

1961PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1962 hostname. This is wrong, because it relates to the incoming message (and
1963 probably the interface on which it is arriving) and not to the outgoing
1964 callout (which could be using a different interface). This has been
1965 changed to use the value of the helo_data option from the smtp transport
1966 instead - this is what is used when a message is actually being sent. If
1967 there is no remote transport (possible with a router that sets up host
1968 addresses), $smtp_active_hostname is used.

14aa5a05 1970PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1971 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1972 (a) The code assumed that strncpy() returns a negative number on buffer
1973 overflow, which isn't the case. Replaced with Exim's string_format()
1974 function.
1975 (b) There were several signed/unsigned issues. I just did the minimum
1976 hacking in of casts. There is scope for a larger refactoring.
1977 (c) The code used strcasecmp() which is not a standard C function.
1978 Replaced with Exim's strcmpic() function.
1979 (d) The code set only $1; it now sets $auth1 as well.
1980 (e) A simple test gave the error "authentication client didn't specify
1981 service in request". It would seem that Dovecot has changed its
1982 interface. Fortunately there's a specification; I followed it and
1983 changed what the client sends and it appears to be working now.

1988PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1989 address A is aliased to B and C, where B exists and C does not. Without
1990 -v the output is "A verified" because verification stops after a
1991 successful redirection if more than one address is generated. However,
1992 with -v the child addresses are also verified. Exim was outputting "A
1993 failed to verify" and then showing the successful verification for C,
1994 with its parentage. It now outputs "B failed to verify", showing B's
1995 parentage before showing the successful verification of C.

1998 look up a TXT record in a specific list after matching in a combined

2000
322050c2
PH
2001PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2002 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2003 they consult the DNS. I had assumed they would set it the way they
2004 wanted; and indeed my experiments on Linux seem to show that in some
2005 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2006 To be on the safe side, however, I have now made the interface to
2007 host_find_byname() similar to host_find_bydns(), with an argument
2008 containing the DNS resolver options. The host_find_byname() function now
2009 sets these options at its start, just as host_find_bydns() does. The smtp
2010 transport options dns_qualify_single and dns_search_parents are passed to
2011 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2012 of host_find_byname() use the default settings of RES_DEFNAMES
2013 (qualify_single) but not RES_DNSRCH (search_parents).

2015PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2016 spool_read_header() do less string testing, by means of a preliminary
2017 switch on the second character of optional "-foo" lines. (This is
2018 overdue, caused by the large number of possibilities that now exist.
2019 Originally there were few.) While I was there, I also converted the
2020 str(n)cmp tests so they don't re-test the leading "-" and the first
2021 character, in the hope this might squeeze out yet more improvement.

PH
2023PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2024 flag allowing group syntax was set by the header_syntax check but not
2025 turned off, possible causing trouble later; (2) The flag was not being
2026 set at all for the header_verify test, causing "group"-style headers to
2027 be rejected. I have now set it in this case, and also caused header_
2028 verify to ignore an empty address taken from a group. While doing this, I
2029 came across some other cases where the code for allowing group syntax
2030 while scanning a header line wasn't quite right (mostly, not resetting
2031 the flag correctly in the right place). These bugs could have caused
2032 trouble for malformed header lines. I hope it is now all correct.

PH
2034PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2035 with the "reply" argument non-NULL. The code, however (which originally
2036 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2037 but it didn't always do it. This confused somebody who was copying the
2038 code for some other use. I have removed all the tests.

PH
2040PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2041 feature that was used to support insecure browsers during the U.S. crypto
2042 embargo. It requires special client support, and Exim is probably the
2043 only MTA that supported it -- and would never use it because real RSA is
2044 always available. This code has been removed, because it had the bad
2045 effect of slowing Exim down by computing (never used) parameters for the
2046 RSA_EXPORT functionality.

PH
2048PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2049 authenticator to fail if there's a tab character in the incoming data
2050 (there should never be unless someone is messing about, as it's supposed
2051 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2052 if the connection is using TLS or if the remote IP is the same as the
2053 local IP, and the "valid-client-cert option" if a client certificate has
2054 been verified.

2085
2086PH/30 Exim was sometimes attempting to deliver messages that had suffered
2087 address errors (4xx response to RCPT) over the same connection as other
2088 messages routed to the same hosts. Such deliveries are always "forced",
2089 so retry times are not inspected. This resulted in far too many retries
2090 for the affected addresses. The effect occurred only when there were more
2091 hosts than the hosts_max_try setting in the smtp transport when it had
2092 the 4xx errors. Those hosts that it had tried were not added to the list
2093 of hosts for which the message was waiting, so if all were tried, there
2094 was no problem. Two fixes have been applied:
2095
2096 (i) If there are any address or message errors in an SMTP delivery, none
2097 of the hosts (tried or untried) are now added to the list of hosts
2098 for which the message is waiting, so the message should not be a
2099 candidate for sending over the same connection that was used for a
2100 successful delivery of some other message. This seems entirely
2101 reasonable: after all the message is NOT "waiting for some host".
2102 This is so "obvious" that I'm not sure why it wasn't done
2103 previously. Hope I haven't missed anything, but it can't do any
2104 harm, as the worst effect is to miss an optimization.
2105
2106 (ii) If, despite (i), such a delivery is accidentally attempted, the
2107 routing retry time is respected, so at least it doesn't keep
2108 hammering the server.

2123PH/35 The error "getsockname() failed: connection reset by peer" was being
2124 written to the panic log as well as the main log, but it isn't really
2125 panic-worthy as it just means the connection died rather early on. I have
2126 removed the panic log writing for the ECONNRESET error when getsockname()
2127 fails.
2128
48c7f9e2
PH
2129PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2130 runs only) independently of the message's sender address. This meant
2131 that, if the 4xx error was in fact related to the sender, a different
2132 message to the same recipient with a different sender could confuse
2133 things. In particualar, this can happen when sending to a greylisting
2134 server, but other circumstances could also provoke similar problems.
2135 I have changed the default so that the retry time for these errors is now
2136 based a combination of the sender and recipient addresses. This change
2137 can be overridden by setting address_retry_include_sender=false in the
2138 smtp transport.

2406PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2408 Unfortunately, if there is a major crisis, such as a disk failure,
2409 tcp-wrappers gives "deny", whereas what one would like would be some
2410 kind of temporary error. A kludge has been added to help with this.
2411 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2412 554 error is used if errno is still zero or contains ENOENT (which occurs
2413 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2414 451 error is used.

2450PH/01 The code for finding all the local interface addresses on a FreeBSD
2451 system running IPv6 was broken. This may well have applied to all BSD
2452 systems, as well as to others that have similar system calls. The broken
2453 code found IPv4 interfaces correctly, but gave incorrect values for the
2454 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2455 that it would not match correctly against @[] and not recognize the IPv6
2456 addresses as local.

2499 autoreply, Exim could try to deliver to a non-existent relative file

2535 Instead, it always explicitly searches for A/AAAA records. This avoids
2536 major problems that occur when a DNS server includes only records of one
2537 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2538 fixed another bug: if SRV records were looked up and the corresponding
2539 address records were *not* found in the additional section, the port
2540 values from the SRV records were lost.

2550PH/19 When calculating a retry time, Exim used to measure the "time since
2551 failure" by looking at the "first failed" field in the retry record. Now
2552 it does not use this if it is later than than the arrival time of the
2553 message. Instead it uses the arrival time. This makes for better
2554 behaviour in cases where some deliveries succeed, thus re-setting the
2555 "first failed" field. An example is a quota failure for a huge message
2556 when small messages continue to be delivered. Without this change, the
2557 "time since failure" will always be short, possible causing more frequent
2558 delivery attempts for the huge message than are intended.

2655PH/42 The content-scanning code uses fopen() to create files in which to put
2656 message data. Previously it was not paying any attention to the mode of
2657 the files. Exim runs with umask(0) because the rest of the code creates
2658 files with open(), and sets the required mode explicitly. Thus, these
2659 files were ending up world-writeable. This was not a big issue, because,
2660 being within the spool directory, they were not world-accessible. I have
2661 created a function called modefopen, which takes an additional mode
2662 argument. It sets umask(777), creates the file, chmods it to the required
2663 mode, then resets the umask. All the relevant calls to fopen() in the

2704 was used in LMTP mode. This meant that they could be retried too
2705 frequently, and not timed out correctly.
2706
2707 (ii) Exim was setting the flag that allows error details to be returned
2708 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2709 recipients that were returned after the DATA command.
2710
2711PH/53 This is related to PH/52, but is more general: for any failing address,
2712 when detailed error information was permitted to be returned to the

2771PH/68 The bounce_return_message and bounce_return_body options were not being

2774 been fixed. However, if bounce_return_message is true and bounce_return_
2775 body is false, the headers that are returned for a non-SMTP message

PH
2785PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2786 function verify_get_ident() calls ip_connect() to connect a socket, but
2787 if the "connect()" function timed out, ip_connect() used to close the
2788 socket. However, verify_get_ident() also closes the socket later, and in
2789 between Exim writes to the log, which may get opened at this point. When
2790 the socket was closed in ip_connect(), the log could get the same file
2791 descriptor number as the socket. This naturally causes chaos. The fix is
2792 not to close the socket in ip_connect(); the socket should be closed by
2793 the function that creates it. There was only one place in the code where
2794 this was missing, in the iplookup router, which I don't think anybody now
2795 uses, but I've fixed it anyway.

2814PH/02 Several tidies to the handling of ${prvs and ${prvscheck:

2817 not a single digit.
2818
2819 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2820 string.
2821
2822 (3) Reset the variables that are obtained from the first argument of
2823 ${prvscheck and used in the second argument before leaving the code,
2824 because their memory is reclaimed, so using them afterwards may do
2825 silly things.
2826
2827 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2828 one (it's much easier than Tom thought :-).
2829
2830 (5) Because of (4), we can now allow for the use of $prvscheck_result
2831 inside the third argument.

2845 This has been changed so that it extracts the operative address. There
2846 may be more than one such address. If so, they are comma-separated, like

PH
2851PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2852 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2853 not being looked up in the rDNS to get a host name, Exim was showing the
2854 IP address twice in Received: lines, even though the IP addresses were
2855 identical. For example:
2856
2857 Received: from [1.2.3.4] (helo=[1.2.3.4])
2858
2859 However, if the real host name was known, it was omitting the HELO data
2860 if it matched the actual IP address. This has been tidied up so that it
2861 doesn't show the same IP address twice.

2887PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2889
2890 Auto-submitted: auto-generated
2891
2892 in the messages that it generates (bounce messages and others, such as
2893 warnings). In the case of bounce messages for non-SMTP mesages, there was
2894 also a typo: it was using "Auto_submitted" (underscore instead of
2895 hyphen). Since every message generated by Exim is necessarily in response
2896 to another message, thes have all been changed to:
2897
2898 Auto-Submitted: auto-replied
2899
2900 in accordance with these statements in the RFC:
2901
2902 The auto-replied keyword:
2903
2904 - SHOULD be used on messages sent in direct response to another
2905 message by an automatic process,
2906
2907 - MUST NOT be used on manually-generated messages,
2908
2909 - MAY be used on Delivery Status Notifications (DSNs) and Message
2910 Disposition Notifications (MDNs),

2950PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2951 canonical form (as documented). However, after a host name lookup from
2952 the IP address, check_host() was doing a simple string comparison with
2953 addresses acquired from the DNS when checking that the found name did
2954 have the original IP as one of its addresses. Since any found IPv6
2955 addresses are likely to be in abbreviated form, the comparison could
2956 fail. Luckily, there already exists a function for doing the comparison
2957 by converting both addresses to binary, so now that is used instead of
2958 the text comparison.

PH
2960PH/20 There was another similar case to PH/19, when a complete host name was

3255PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3256 with the definition in sysexits.h (which is #included earlier).
3257 Fortunately, Exim does not actually use EX_OK. The code used to try to
3258 preserve the sysexits.h value, by assumimg that macro definitions were
3259 scanned for macro replacements. I have been disabused of this notion,
3260 so now the code just undefines EX_OK before #including unistd.h.

3262PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3263 in the smtp transport. When a block could not be written in a single
3264 write() function, the timeout was being re-applied to each part-write.
3265 This seems wrong - if the receiver was accepting one byte at a time it
3266 would take for ever. The timeout is now adjusted when this happens. It
3267 doesn't have to be particularly precise.
