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.

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

54 different interface settings and the retry behaviour needs to be kept
55 distinct.

71JH/14 Change header file name for freeradius-client. Relevant if compiling

JH
81JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
82 defaults to "*" (all hosts). The variable is now available when not built
83 with TLS, default unset, mainly to enable keeping the testuite sane.
84 If a server certificate is not supplied (via tls_certificate) an error is
85 logged, and clients will find TLS connections fail on startup. Presumably
86 they will retry in-clear.
87 Packagers of Exim are strongly encouraged to create a server certificate
88 at installation time.

90HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
91 with the $config_file variable.
92
5ef5dd52
JB
93JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
94 in transport context, after the attempt, and per-recipient. The latter type
95 is per host attempted. The event data is the error message, and the errno
96 information encodes the lookup type (A vs. MX) used for the (first) host,
97 and the trailing two digits of the smtp 4xx reponse.

99GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
100 to write to mainlog (or rejectlog, paniclog) in the window between file
101 creation and permissions/ownership being changed. Particularly affects
102 installations where exicyclog is run as root, rather than exim user;
103 result is that the running daemon panics and dies.

243 Normally benign, it bites when the pair was led to by a CNAME;

268Exim version 4.85
269-----------------
270TL/01 When running the test suite, the README says that variables such as
271 no_msglog_check are global and can be placed anywhere in a specific
272 test's script, however it was observed that placement needed to be near
273 the beginning for it to behave that way. Changed the runtest perl
274 script to read through the entire script once to detect and set these
275 variables, reset to the beginning of the script, and then run through
276 the script parsing/test process like normal.

303JH/05 Fix results-pipe from transport process. Several recipients, combined
304 with certificate use, exposed issues where response data items split
305 over buffer boundaries were not parsed properly. This eventually
306 resulted in duplicates being sent. This issue only became common enough

381
382 When a message was received over SMTP with TLS, Exim failed to clear up
383 the incoming connection properly after forking off the child process to
384 deliver the message. In some situations the subsequent outgoing
385 delivery connection happened to have the same fd number as the incoming
386 connection previously had. Exim would try to use TLS and fail, logging

633TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
634
635 When a queue runner is handling a message, Exim first routes the
636 recipient addresses, during which it prunes them based on the retry
637 hints database. After that it attempts to deliver the message to
638 any remaining recipients. It then updates the hints database using
639 the retry rules.
640
641 So if a recipient address works intermittently, it can get repeatedly
642 deferred at routing time. The retry hints record remains fresh so the
643 address never reaches the final cutoff time.
644
645 This is a fairly common occurrence when a user is bumping up against
646 their storage quota. Exim had some logic in its local delivery code
647 to deal with this. However it did not apply to per-recipient defers
648 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
649
1ddeb334
TF
650 This change adds a proper retry rule check during routing so that the
651 final cutoff time is checked against the message's age. We only do
652 this check if there is an address retry record and there is not a
653 domain retry record; this implies that previous attempts to handle
654 the address had the retry_use_local_parts option turned on. We use
655 this as an approximation for the destination being like a local
656 delivery, as in LMTP.
67bd1ab3
TF
657
658 I suspect this new check makes the old local delivery cutoff check
659 redundant, but I have not verified this so I left the code in place.

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

694 Server implementation by Todd Lyons, client by JH.

698 acl_data_smtp_prdr ACL is called once for each recipient, after
699 the body content is received and before the acl_smtp_data ACL.
700 The client is controlled by bolth of: a hosts_try_prdr option
701 on the smtp transport, and the server advertisement.
702 Default client logging of deliveries and rejections involving

981TF/03 Make the exiwhat support code safe for signals. Previously Exim might
982 lock up or crash if it happened to be inside a call to libc when it
983 got a SIGUSR1 from exiwhat.
984
985 The SIGUSR1 handler appends the current process status to the process
986 log which is later printed by exiwhat. It used to use the general
987 purpose logging code to do this, but several functions it calls are
988 not safe for signals.
989
990 The new output code in the SIGUSR1 handler is specific to the process
991 log, and simple enough that it's easy to inspect for signal safety.
992 Removing some special cases also simplifies the general logging code.
993 Removing the spurious timestamps from the process log simplifies
994 exiwhat.

TF
996TF/04 Improved ratelimit ACL condition.
997
998 The /noupdate option has been deprecated in favour of /readonly which
999 has clearer semantics. The /leaky, /strict, and /readonly update modes
1000 are mutually exclusive. The update mode is no longer included in the
1001 database key; it just determines when the database is updated. (This
1002 means that when you upgrde Exim will forget old rate measurements.)
1003
1004 Exim now checks that the per_* options are used with an update mode that
1005 makes sense for the current ACL. For example, when Exim is processing a
1006 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1007 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1008 must specify per_mail/readonly. If you omit the update mode it defaults to
1009 /leaky where that makes sense (as before) or /readonly where required.
1010
1011 The /noupdate option is now undocumented but still supported for
1012 backwards compatibility. It is equivalent to /readonly except that in
1013 ACLs where /readonly is required you may specify /leaky/noupdate or
1014 /strict/noupdate which are treated the same as /readonly.
1015
1016 A useful new feature is the /count= option. This is a generalization
1017 of the per_byte option, so that you can measure the throughput of other
1018 aggregate values. For example, the per_byte option is now equivalent
1019 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1020
1021 The per_rcpt option has been generalized using the /count= mechanism
1022 (though it's more complicated than the per_byte equivalence). When it is
1023 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1024 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1025 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1026 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1027 Note that using per_rcpt with a non-readonly update mode in more than
1028 one ACL will cause the recipients to be double-counted. (The per_mail
1029 and per_byte options don't have this problem.)
1030
1031 The handling of very low rates has changed slightly. If the computed rate
1032 is less than the event's count (usually one) then this event is the first
1033 after a long gap. In this case the rate is set to the same as this event's
1034 count, so that the first message of a spam run is counted properly.
1035
1036 The major new feature is a mechanism for counting the rate of unique
1037 events. The new per_addr option counts the number of different
1038 recipients that someone has sent messages to in the last time period. It
1039 behaves like per_rcpt if all the recipient addresses are different, but
1040 duplicate recipient addresses do not increase the measured rate. Like
1041 the /count= option this is a general mechanism, so the per_addr option
1042 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1043 example, measure the rate that a client uses different sender addresses
1044 with the options per_mail/unique=$sender_address. There are further
1045 details in the main documentation.

1596 were called 'true' and it seems that C99 defines that as a reserved

1598 not include C99-style headers which use bools without triggering

1618
6a3bceb1
PH
1619PH/02 When an IPv6 address is converted to a string for single-key lookup
1620 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1621 dots are used instead of colons so that keys in lsearch files need not
1622 contain colons. This was done some time before quoting was made available
1623 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1624 (notated using the quote facility) so as to distinguish them from IPv4
1625 keys. This meant that lookups for IP addresses in host lists did not work
1626 for iplsearch lookups.
1627
1628 This has been fixed by arranging for IPv6 addresses to be expressed with
1629 colons if the lookup type is iplsearch. This is not incompatible, because
1630 previously such lookups could never work.
1631
1632 The situation is now rather anomolous, since one *can* have colons in
1633 ordinary lsearch keys. However, making the change in all cases is
1634 incompatible and would probably break a number of configurations.

1639MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1640 conversion specification without a maximum field width, thereby enabling
1641 a rogue spamd server to cause a buffer overflow. While nobody in their
1642 right mind would setup Exim to query an untrusted spamd server, an
1643 attacker that gains access to a server running spamd could potentially
1644 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1649MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1650 a directory entry by the name of the lookup key. Previously, if a
1651 symlink pointed to a non-existing file or a file in a directory that
1652 Exim lacked permissions to read, a lookup for a key matching that
1653 symlink would fail. Now it is enough that a matching directory entry
1654 exists, symlink or not. (Bugzilla 503.)

1837PH/29 SMTP synchronization checks are implemented when a command is read -
1838 there is a check that no more input is waiting when there shouldn't be
1839 any. However, for some commands, a delay in an ACL can mean that it is
1840 some time before the response is written. In this time, more input might
1841 arrive, invalidly. So now there are extra checks after an ACL has run for
1842 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1843 pipelining has not been advertised.

1855PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1857 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1858 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1859 was a macro that became an assignment, so it seemed to work. This has
1860 changed to a proper function call with a void return, hence the compile
1861 error. Exim's code has been fixed.

1899 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1917 the response to the final '.' that terminates a message, but only in the
1918 case where the client has not sent further data following the '.'
1919 (unfortunately, this is allowed). However, in many cases there won't be
1920 any further data because there won't be any more messages to send. A call
1921 to select() can be used: if it shows that the input is "ready", there is
1922 either input waiting, or the socket has been closed. An attempt to read
1923 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1924 would have sent an OK response which the client would never have see.

1933-----------------
1934
1935PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1936 fixed by 4.65/MH/01 (is this a record?) are fixed:
1937
1938 (i) An empty string was always treated as zero by the numeric comparison
1939 operators. This behaviour has been restored.
1940
1941 (ii) It is documented that the numeric comparison operators always treat
1942 their arguments as decimal numbers. This was broken in that numbers
1943 starting with 0 were being interpreted as octal.
1944
1945 While fixing these problems I realized that there was another issue that
1946 hadn't been noticed. Values of message_size_limit (both the global option

1974TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1975 leftover -K file (the existence of which was triggered by #402).

1984TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
1993PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1994 callout verification, Exim cached a "reject" for the entire domain. This
1995 is correct for most verifications, but it is not correct for a recipient
1996 verification with use_sender or use_postmaster set, because in that case
1997 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1998 case of MAIL FROM:<> rejection from other early rejections (e.g.
1999 rejection of HELO). When verifying a recipient using a non-null MAIL
2000 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2001 Whatever the result of the callout, the value of the domain cache is
2002 left unchanged (for any other kind of callout, getting as far as trying
2003 RCPT means that the domain itself is ok).

2037PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2039 probably the interface on which it is arriving) and not to the outgoing
2040 callout (which could be using a different interface). This has been
2041 changed to use the value of the helo_data option from the smtp transport
2042 instead - this is what is used when a message is actually being sent. If
2043 there is no remote transport (possible with a router that sets up host
2044 addresses), $smtp_active_hostname is used.

7befa435 2047 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2048 (a) The code assumed that strncpy() returns a negative number on buffer
2049 overflow, which isn't the case. Replaced with Exim's string_format()
2050 function.
2051 (b) There were several signed/unsigned issues. I just did the minimum
2052 hacking in of casts. There is scope for a larger refactoring.
2053 (c) The code used strcasecmp() which is not a standard C function.
2054 Replaced with Exim's strcmpic() function.
2055 (d) The code set only $1; it now sets $auth1 as well.
2056 (e) A simple test gave the error "authentication client didn't specify
2057 service in request". It would seem that Dovecot has changed its
2058 interface. Fortunately there's a specification; I followed it and
2059 changed what the client sends and it appears to be working now.

2065 address A is aliased to B and C, where B exists and C does not. Without
2066 -v the output is "A verified" because verification stops after a
2067 successful redirection if more than one address is generated. However,
2068 with -v the child addresses are also verified. Exim was outputting "A
2069 failed to verify" and then showing the successful verification for C,
2070 with its parentage. It now outputs "B failed to verify", showing B's
2071 parentage before showing the successful verification of C.

2076
322050c2
PH
2077PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2078 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2079 they consult the DNS. I had assumed they would set it the way they
2080 wanted; and indeed my experiments on Linux seem to show that in some
2081 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2082 To be on the safe side, however, I have now made the interface to
2083 host_find_byname() similar to host_find_bydns(), with an argument
2084 containing the DNS resolver options. The host_find_byname() function now
2085 sets these options at its start, just as host_find_bydns() does. The smtp
2086 transport options dns_qualify_single and dns_search_parents are passed to
2087 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2088 of host_find_byname() use the default settings of RES_DEFNAMES
2089 (qualify_single) but not RES_DNSRCH (search_parents).

2092 spool_read_header() do less string testing, by means of a preliminary
2093 switch on the second character of optional "-foo" lines. (This is
2094 overdue, caused by the large number of possibilities that now exist.
2095 Originally there were few.) While I was there, I also converted the
2096 str(n)cmp tests so they don't re-test the leading "-" and the first
2097 character, in the hope this might squeeze out yet more improvement.

2099PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2100 flag allowing group syntax was set by the header_syntax check but not
2101 turned off, possible causing trouble later; (2) The flag was not being
2102 set at all for the header_verify test, causing "group"-style headers to
2103 be rejected. I have now set it in this case, and also caused header_
2104 verify to ignore an empty address taken from a group. While doing this, I
2105 came across some other cases where the code for allowing group syntax
2106 while scanning a header line wasn't quite right (mostly, not resetting
2107 the flag correctly in the right place). These bugs could have caused
2108 trouble for malformed header lines. I hope it is now all correct.

2110PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2113 but it didn't always do it. This confused somebody who was copying the
2114 code for some other use. I have removed all the tests.

PH
2116PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2117 feature that was used to support insecure browsers during the U.S. crypto
2118 embargo. It requires special client support, and Exim is probably the
2119 only MTA that supported it -- and would never use it because real RSA is
2120 always available. This code has been removed, because it had the bad
2121 effect of slowing Exim down by computing (never used) parameters for the
2122 RSA_EXPORT functionality.

2127 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2128 if the connection is using TLS or if the remote IP is the same as the
2129 local IP, and the "valid-client-cert option" if a client certificate has
2130 been verified.

2161
2162PH/30 Exim was sometimes attempting to deliver messages that had suffered
2163 address errors (4xx response to RCPT) over the same connection as other
2164 messages routed to the same hosts. Such deliveries are always "forced",
2165 so retry times are not inspected. This resulted in far too many retries
2166 for the affected addresses. The effect occurred only when there were more
2167 hosts than the hosts_max_try setting in the smtp transport when it had
2168 the 4xx errors. Those hosts that it had tried were not added to the list
2169 of hosts for which the message was waiting, so if all were tried, there
2170 was no problem. Two fixes have been applied:
2171
2172 (i) If there are any address or message errors in an SMTP delivery, none
2173 of the hosts (tried or untried) are now added to the list of hosts
2174 for which the message is waiting, so the message should not be a
2175 candidate for sending over the same connection that was used for a
2176 successful delivery of some other message. This seems entirely
2177 reasonable: after all the message is NOT "waiting for some host".
2178 This is so "obvious" that I'm not sure why it wasn't done
2179 previously. Hope I haven't missed anything, but it can't do any
2180 harm, as the worst effect is to miss an optimization.
2181
2182 (ii) If, despite (i), such a delivery is accidentally attempted, the
2183 routing retry time is respected, so at least it doesn't keep
2184 hammering the server.

PH
2199PH/35 The error "getsockname() failed: connection reset by peer" was being
2200 written to the panic log as well as the main log, but it isn't really
2201 panic-worthy as it just means the connection died rather early on. I have
2202 removed the panic log writing for the ECONNRESET error when getsockname()
2203 fails.
2204
48c7f9e2
PH
2205PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2206 runs only) independently of the message's sender address. This meant
2207 that, if the 4xx error was in fact related to the sender, a different
2208 message to the same recipient with a different sender could confuse
2209 things. In particualar, this can happen when sending to a greylisting
2210 server, but other circumstances could also provoke similar problems.
2211 I have changed the default so that the retry time for these errors is now
2212 based a combination of the sender and recipient addresses. This change
2213 can be overridden by setting address_retry_include_sender=false in the
2214 smtp transport.

2484 Unfortunately, if there is a major crisis, such as a disk failure,
2485 tcp-wrappers gives "deny", whereas what one would like would be some
2486 kind of temporary error. A kludge has been added to help with this.
2487 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2488 554 error is used if errno is still zero or contains ENOENT (which occurs
2489 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2490 451 error is used.

2529 code found IPv4 interfaces correctly, but gave incorrect values for the
2530 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2531 that it would not match correctly against @[] and not recognize the IPv6
2532 addresses as local.

2575 autoreply, Exim could try to deliver to a non-existent relative file

2611 Instead, it always explicitly searches for A/AAAA records. This avoids
2612 major problems that occur when a DNS server includes only records of one
2613 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2614 fixed another bug: if SRV records were looked up and the corresponding
2615 address records were *not* found in the additional section, the port
2616 values from the SRV records were lost.

2618PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2626PH/19 When calculating a retry time, Exim used to measure the "time since
2627 failure" by looking at the "first failed" field in the retry record. Now
2628 it does not use this if it is later than than the arrival time of the
2629 message. Instead it uses the arrival time. This makes for better
2630 behaviour in cases where some deliveries succeed, thus re-setting the
2631 "first failed" field. An example is a quota failure for a huge message
2632 when small messages continue to be delivered. Without this change, the
2633 "time since failure" will always be short, possible causing more frequent
2634 delivery attempts for the huge message than are intended.

PH
2731PH/42 The content-scanning code uses fopen() to create files in which to put
2732 message data. Previously it was not paying any attention to the mode of
2733 the files. Exim runs with umask(0) because the rest of the code creates
2734 files with open(), and sets the required mode explicitly. Thus, these
2735 files were ending up world-writeable. This was not a big issue, because,
2736 being within the spool directory, they were not world-accessible. I have
2737 created a function called modefopen, which takes an additional mode
2738 argument. It sets umask(777), creates the file, chmods it to the required
2739 mode, then resets the umask. All the relevant calls to fopen() in the
2740 content scanning code have been changed to use this function.

2749 challenges are checked to ensure they are valid base64 strings. By
2750 default, the authentication attempt is cancelled if an invalid string is
2751 received. Setting client_ignore_invalid_base64 true ignores these errors.
2752 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2753 they are received. Thus, the responses can be made to depend on the
2754 challenges. If an invalid string is ignored, an empty string is placed in

2775PH/52 Two bugs concerned with error handling when the smtp transport is
2776 used in LMTP mode:
2777
2778 (i) Exim was not creating retry information for temporary errors given
2779 for individual recipients after the DATA command when the smtp transport
2780 was used in LMTP mode. This meant that they could be retried too
2781 frequently, and not timed out correctly.
2782
2783 (ii) Exim was setting the flag that allows error details to be returned
2784 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2785 recipients that were returned after the DATA command.
2786
2787PH/53 This is related to PH/52, but is more general: for any failing address,
2788 when detailed error information was permitted to be returned to the
2789 sender, but the error was temporary, then after the final timeout, only
2790 "retry timeout exceeded" was returned. Now it returns the full error as
2791 well as "retry timeout exceeded".

2861PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2862 function verify_get_ident() calls ip_connect() to connect a socket, but
2863 if the "connect()" function timed out, ip_connect() used to close the
2864 socket. However, verify_get_ident() also closes the socket later, and in
2865 between Exim writes to the log, which may get opened at this point. When
2866 the socket was closed in ip_connect(), the log could get the same file
2867 descriptor number as the socket. This naturally causes chaos. The fix is
2868 not to close the socket in ip_connect(); the socket should be closed by
2869 the function that creates it. There was only one place in the code where
2870 this was missing, in the iplookup router, which I don't think anybody now
2871 uses, but I've fixed it anyway.

2894
2895 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2896 string.
2897
2898 (3) Reset the variables that are obtained from the first argument of
2899 ${prvscheck and used in the second argument before leaving the code,
2900 because their memory is reclaimed, so using them afterwards may do
2901 silly things.
2902
2903 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2904 one (it's much easier than Tom thought :-).

2927PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2928 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2929 not being looked up in the rDNS to get a host name, Exim was showing the
2930 IP address twice in Received: lines, even though the IP addresses were
2931 identical. For example:
2932
2933 Received: from [1.2.3.4] (helo=[1.2.3.4])
2934
2935 However, if the real host name was known, it was omitting the HELO data
2936 if it matched the actual IP address. This has been tidied up so that it
2937 doesn't show the same IP address twice.

2963PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2965
2966 Auto-submitted: auto-generated
2967
2968 in the messages that it generates (bounce messages and others, such as
2969 warnings). In the case of bounce messages for non-SMTP mesages, there was
2970 also a typo: it was using "Auto_submitted" (underscore instead of
2971 hyphen). Since every message generated by Exim is necessarily in response
2972 to another message, thes have all been changed to:
2973
2974 Auto-Submitted: auto-replied
2975
2976 in accordance with these statements in the RFC:
2977
2978 The auto-replied keyword:
2979
2980 - SHOULD be used on messages sent in direct response to another
2981 message by an automatic process,
2982
2983 - MUST NOT be used on manually-generated messages,

3028 the IP address, check_host() was doing a simple string comparison with
3029 addresses acquired from the DNS when checking that the found name did
3030 have the original IP as one of its addresses. Since any found IPv6
3031 addresses are likely to be in abbreviated form, the comparison could
3032 fail. Luckily, there already exists a function for doing the comparison
3033 by converting both addresses to binary, so now that is used instead of
3034 the text comparison.

3141PH/20 If a delivery was routed to a non-standard port by means of an SRV

3151PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3152 authentication with radiusclient 0.4.9:
3153
3154 - Error returned from rc_read_config was caught wrongly
3155 - Username/password not passed on to radius server due to wrong length.
3156
3157 The presumption is that some radiusclient API changes for 4.51/PH/17
3158 were not taken care of correctly. The code is still untested by me (my
3159 Linux distribution still has 0.3.2 of radiusclient), but it was
3160 contributed by a Radius user.

3175PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
3176 commands, but it was not correctly comparing the address with the actual

3178 header lines when this was not necessary.

3182PH/28 Exim tries to create and chdir to its spool directory when it starts;
3183 it should be ignoring failures (because with -C, for example, it has lost

3203PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
3204 Local/Makefile (with some defaults set). These are used in built scripts
3205 such as exicyclog, but they have never been used in the exim_install
3206 script (though there are many overriding facilities there). I have
3207 arranged that the exim_install script now takes note of these two

3212PH/36 When a locally submitted message by a trusted user did not contain a
3213 From: header, and the sender address was obtained from -f or from an SMTP
3214 MAIL command, and the trusted user did not use -F to supply a sender
3215 name, $originator_name was incorrectly used when constructing a From:
3216 header. Furthermore, $originator_name was used for submission mode
3217 messages from external hosts without From: headers in a similar way,
3218 which is clearly wrong.

3222PH/38 When log_selector = +received_sender was set, and the addition of the

3308PH/03 The warning log line about a condition test deferring for a "warn" verb
3309 was being output only once per connection, rather than after each

3313TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
