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.

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

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

37JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
38 to DSN fail messages (bounces): remote IP, remote greeting, remote response
39 to HELO, local diagnostic string.

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.

50 matter for fast-change records such as DNSBLs.
51

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

55 distinct.

80

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

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.
98

GF
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.

108 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
109 "pri" and "weight". Note that the previous implicit priority given by the
110 list order is no longer honoured.

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

210 (and we were inconsistent anyway for A-only vs AAAA+A).

233Exim version 4.85
234-----------------
235TL/01 When running the test suite, the README says that variables such as
236 no_msglog_check are global and can be placed anywhere in a specific
237 test's script, however it was observed that placement needed to be near
238 the beginning for it to behave that way. Changed the runtest perl
239 script to read through the entire script once to detect and set these
240 variables, reset to the beginning of the script, and then run through
241 the script parsing/test process like normal.

268JH/05 Fix results-pipe from transport process. Several recipients, combined
269 with certificate use, exposed issues where response data items split
270 over buffer boundaries were not parsed properly. This eventually
271 resulted in duplicates being sent. This issue only became common enough
272 to notice due to the introduction of conection certificate information,
273 the item size being so much larger. Found and fixed by Wolfgang Breyha.

aec45841 285 and $event_defer_errno. There is a new variable $verify_mode, usable in

346
347 When a message was received over SMTP with TLS, Exim failed to clear up
348 the incoming connection properly after forking off the child process to
349 deliver the message. In some situations the subsequent outgoing
350 delivery connection happened to have the same fd number as the incoming
351 connection previously had. Exim would try to use TLS and fail, logging

598TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
599
600 When a queue runner is handling a message, Exim first routes the
601 recipient addresses, during which it prunes them based on the retry
602 hints database. After that it attempts to deliver the message to
603 any remaining recipients. It then updates the hints database using
604 the retry rules.
605
606 So if a recipient address works intermittently, it can get repeatedly
607 deferred at routing time. The retry hints record remains fresh so the
608 address never reaches the final cutoff time.
609
610 This is a fairly common occurrence when a user is bumping up against
611 their storage quota. Exim had some logic in its local delivery code
612 to deal with this. However it did not apply to per-recipient defers
613 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
614
1ddeb334
TF
615 This change adds a proper retry rule check during routing so that the
616 final cutoff time is checked against the message's age. We only do
617 this check if there is an address retry record and there is not a
618 domain retry record; this implies that previous attempts to handle
619 the address had the retry_use_local_parts option turned on. We use
620 this as an approximation for the destination being like a local
621 delivery, as in LMTP.
67bd1ab3
TF
622
623 I suspect this new check makes the old local delivery cutoff check
624 redundant, but I have not verified this so I left the code in place.

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

659 Server implementation by Todd Lyons, client by JH.
660 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
661 config variable "prdr_enable" controls whether the server
662 advertises the facility. If the client requests PRDR a new
663 acl_data_smtp_prdr ACL is called once for each recipient, after
664 the body content is received and before the acl_smtp_data ACL.
665 The client is controlled by bolth of: a hosts_try_prdr option
666 on the smtp transport, and the server advertisement.
667 Default client logging of deliveries and rejections involving
668 PRDR are flagged with the string "PRDR".

946TF/03 Make the exiwhat support code safe for signals. Previously Exim might
947 lock up or crash if it happened to be inside a call to libc when it
948 got a SIGUSR1 from exiwhat.
949
950 The SIGUSR1 handler appends the current process status to the process
951 log which is later printed by exiwhat. It used to use the general
952 purpose logging code to do this, but several functions it calls are
953 not safe for signals.
954
955 The new output code in the SIGUSR1 handler is specific to the process
956 log, and simple enough that it's easy to inspect for signal safety.
957 Removing some special cases also simplifies the general logging code.
958 Removing the spurious timestamps from the process log simplifies
959 exiwhat.
960
c99ce5c9
TF
961TF/04 Improved ratelimit ACL condition.
962
963 The /noupdate option has been deprecated in favour of /readonly which
964 has clearer semantics. The /leaky, /strict, and /readonly update modes
965 are mutually exclusive. The update mode is no longer included in the
966 database key; it just determines when the database is updated. (This
967 means that when you upgrde Exim will forget old rate measurements.)
968
969 Exim now checks that the per_* options are used with an update mode that
970 makes sense for the current ACL. For example, when Exim is processing a
971 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
972 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
973 must specify per_mail/readonly. If you omit the update mode it defaults to
974 /leaky where that makes sense (as before) or /readonly where required.
975
976 The /noupdate option is now undocumented but still supported for
977 backwards compatibility. It is equivalent to /readonly except that in
978 ACLs where /readonly is required you may specify /leaky/noupdate or
979 /strict/noupdate which are treated the same as /readonly.
980
981 A useful new feature is the /count= option. This is a generalization
982 of the per_byte option, so that you can measure the throughput of other
983 aggregate values. For example, the per_byte option is now equivalent
984 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
985
986 The per_rcpt option has been generalized using the /count= mechanism
987 (though it's more complicated than the per_byte equivalence). When it is
988 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
989 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
990 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
991 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
992 Note that using per_rcpt with a non-readonly update mode in more than
993 one ACL will cause the recipients to be double-counted. (The per_mail
994 and per_byte options don't have this problem.)
995
996 The handling of very low rates has changed slightly. If the computed rate
997 is less than the event's count (usually one) then this event is the first
998 after a long gap. In this case the rate is set to the same as this event's
999 count, so that the first message of a spam run is counted properly.
1000
1001 The major new feature is a mechanism for counting the rate of unique
1002 events. The new per_addr option counts the number of different
1003 recipients that someone has sent messages to in the last time period. It
1004 behaves like per_rcpt if all the recipient addresses are different, but
1005 duplicate recipient addresses do not increase the measured rate. Like
1006 the /count= option this is a general mechanism, so the per_addr option
1007 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1008 example, measure the rate that a client uses different sender addresses
1009 with the options per_mail/unique=$sender_address. There are further
1010 details in the main documentation.

1582PH/01 Another patch from the Sieve maintainer.
1583
6a3bceb1
PH
1584PH/02 When an IPv6 address is converted to a string for single-key lookup
1585 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1586 dots are used instead of colons so that keys in lsearch files need not
1587 contain colons. This was done some time before quoting was made available
1588 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1589 (notated using the quote facility) so as to distinguish them from IPv4
1590 keys. This meant that lookups for IP addresses in host lists did not work
1591 for iplsearch lookups.
1592
1593 This has been fixed by arranging for IPv6 addresses to be expressed with
1594 colons if the lookup type is iplsearch. This is not incompatible, because
1595 previously such lookups could never work.
1596
1597 The situation is now rather anomolous, since one *can* have colons in
1598 ordinary lsearch keys. However, making the change in all cases is
1599 incompatible and would probably break a number of configurations.

1604MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1605 conversion specification without a maximum field width, thereby enabling
1606 a rogue spamd server to cause a buffer overflow. While nobody in their
1607 right mind would setup Exim to query an untrusted spamd server, an
1608 attacker that gains access to a server running spamd could potentially
1609 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1614MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1615 a directory entry by the name of the lookup key. Previously, if a
1616 symlink pointed to a non-existing file or a file in a directory that
1617 Exim lacked permissions to read, a lookup for a key matching that
1618 symlink would fail. Now it is enough that a matching directory entry

PH
1802PH/29 SMTP synchronization checks are implemented when a command is read -
1803 there is a check that no more input is waiting when there shouldn't be
1804 any. However, for some commands, a delay in an ACL can mean that it is
1805 some time before the response is written. In this time, more input might
1806 arrive, invalidly. So now there are extra checks after an ACL has run for
1807 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1808 pipelining has not been advertised.

1823 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1824 was a macro that became an assignment, so it seemed to work. This has
1825 changed to a proper function call with a void return, hence the compile
1826 error. Exim's code has been fixed.

PH
1882 the response to the final '.' that terminates a message, but only in the
1883 case where the client has not sent further data following the '.'
1884 (unfortunately, this is allowed). However, in many cases there won't be
1885 any further data because there won't be any more messages to send. A call
1886 to select() can be used: if it shows that the input is "ready", there is
1887 either input waiting, or the socket has been closed. An attempt to read
1888 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1889 would have sent an OK response which the client would never have see.

1900PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1901 fixed by 4.65/MH/01 (is this a record?) are fixed:
1902
1903 (i) An empty string was always treated as zero by the numeric comparison
1904 operators. This behaviour has been restored.
1905
1906 (ii) It is documented that the numeric comparison operators always treat
1907 their arguments as decimal numbers. This was broken in that numbers
1908 starting with 0 were being interpreted as octal.
1909
1910 While fixing these problems I realized that there was another issue that
1911 hadn't been noticed. Values of message_size_limit (both the global option
1912 and the transport option) were treated as octal if they started with 0.
1913 The documentation was vague. These values are now always treated as
1914 decimal, and I will make that clear in the documentation.

1955 header after the first one which had an odd number of characters
1956 in the field name.

PH
1958PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1959 callout verification, Exim cached a "reject" for the entire domain. This
1960 is correct for most verifications, but it is not correct for a recipient
1961 verification with use_sender or use_postmaster set, because in that case
1962 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1963 case of MAIL FROM:<> rejection from other early rejections (e.g.
1964 rejection of HELO). When verifying a recipient using a non-null MAIL
1965 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1966 Whatever the result of the callout, the value of the domain cache is
1967 left unchanged (for any other kind of callout, getting as far as trying
1968 RCPT means that the domain itself is ok).

2002PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2004 probably the interface on which it is arriving) and not to the outgoing
2005 callout (which could be using a different interface). This has been
2006 changed to use the value of the helo_data option from the smtp transport
2007 instead - this is what is used when a message is actually being sent. If
2008 there is no remote transport (possible with a router that sets up host
2009 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2013 (a) The code assumed that strncpy() returns a negative number on buffer
2014 overflow, which isn't the case. Replaced with Exim's string_format()
2015 function.
2016 (b) There were several signed/unsigned issues. I just did the minimum
2017 hacking in of casts. There is scope for a larger refactoring.
2018 (c) The code used strcasecmp() which is not a standard C function.
2019 Replaced with Exim's strcmpic() function.
2020 (d) The code set only $1; it now sets $auth1 as well.
2021 (e) A simple test gave the error "authentication client didn't specify
2022 service in request". It would seem that Dovecot has changed its
2023 interface. Fortunately there's a specification; I followed it and
2024 changed what the client sends and it appears to be working now.

2029PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2030 address A is aliased to B and C, where B exists and C does not. Without
2031 -v the output is "A verified" because verification stops after a
2032 successful redirection if more than one address is generated. However,
2033 with -v the child addresses are also verified. Exim was outputting "A
2034 failed to verify" and then showing the successful verification for C,
2035 with its parentage. It now outputs "B failed to verify", showing B's
2036 parentage before showing the successful verification of C.

PH
2042PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2043 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2044 they consult the DNS. I had assumed they would set it the way they
2045 wanted; and indeed my experiments on Linux seem to show that in some
2046 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2047 To be on the safe side, however, I have now made the interface to
2048 host_find_byname() similar to host_find_bydns(), with an argument
2049 containing the DNS resolver options. The host_find_byname() function now
2050 sets these options at its start, just as host_find_bydns() does. The smtp
2051 transport options dns_qualify_single and dns_search_parents are passed to
2052 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2053 of host_find_byname() use the default settings of RES_DEFNAMES
2054 (qualify_single) but not RES_DNSRCH (search_parents).

2056PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2057 spool_read_header() do less string testing, by means of a preliminary
2058 switch on the second character of optional "-foo" lines. (This is
2059 overdue, caused by the large number of possibilities that now exist.
2060 Originally there were few.) While I was there, I also converted the
2061 str(n)cmp tests so they don't re-test the leading "-" and the first
2062 character, in the hope this might squeeze out yet more improvement.

2064PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2065 flag allowing group syntax was set by the header_syntax check but not
2066 turned off, possible causing trouble later; (2) The flag was not being
2067 set at all for the header_verify test, causing "group"-style headers to
2068 be rejected. I have now set it in this case, and also caused header_
2069 verify to ignore an empty address taken from a group. While doing this, I
2070 came across some other cases where the code for allowing group syntax
2071 while scanning a header line wasn't quite right (mostly, not resetting
2072 the flag correctly in the right place). These bugs could have caused
2073 trouble for malformed header lines. I hope it is now all correct.

2075PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2076 with the "reply" argument non-NULL. The code, however (which originally
2077 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2078 but it didn't always do it. This confused somebody who was copying the
2079 code for some other use. I have removed all the tests.

PH
2081PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2082 feature that was used to support insecure browsers during the U.S. crypto
2083 embargo. It requires special client support, and Exim is probably the
2084 only MTA that supported it -- and would never use it because real RSA is
2085 always available. This code has been removed, because it had the bad
2086 effect of slowing Exim down by computing (never used) parameters for the
2087 RSA_EXPORT functionality.

2092 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2093 if the connection is using TLS or if the remote IP is the same as the
2094 local IP, and the "valid-client-cert option" if a client certificate has
2095 been verified.

2126
2127PH/30 Exim was sometimes attempting to deliver messages that had suffered
2128 address errors (4xx response to RCPT) over the same connection as other
2129 messages routed to the same hosts. Such deliveries are always "forced",
2130 so retry times are not inspected. This resulted in far too many retries
2131 for the affected addresses. The effect occurred only when there were more
2132 hosts than the hosts_max_try setting in the smtp transport when it had
2133 the 4xx errors. Those hosts that it had tried were not added to the list
2134 of hosts for which the message was waiting, so if all were tried, there
2135 was no problem. Two fixes have been applied:
2136
2137 (i) If there are any address or message errors in an SMTP delivery, none
2138 of the hosts (tried or untried) are now added to the list of hosts
2139 for which the message is waiting, so the message should not be a
2140 candidate for sending over the same connection that was used for a
2141 successful delivery of some other message. This seems entirely
2142 reasonable: after all the message is NOT "waiting for some host".
2143 This is so "obvious" that I'm not sure why it wasn't done
2144 previously. Hope I haven't missed anything, but it can't do any
2145 harm, as the worst effect is to miss an optimization.
2146
2147 (ii) If, despite (i), such a delivery is accidentally attempted, the
2148 routing retry time is respected, so at least it doesn't keep
2149 hammering the server.

2164PH/35 The error "getsockname() failed: connection reset by peer" was being
2165 written to the panic log as well as the main log, but it isn't really

2167 removed the panic log writing for the ECONNRESET error when getsockname()
2168 fails.

48c7f9e2
PH
2170PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2171 runs only) independently of the message's sender address. This meant
2172 that, if the 4xx error was in fact related to the sender, a different
2173 message to the same recipient with a different sender could confuse
2174 things. In particualar, this can happen when sending to a greylisting
2175 server, but other circumstances could also provoke similar problems.
2176 I have changed the default so that the retry time for these errors is now
2177 based a combination of the sender and recipient addresses. This change
2178 can be overridden by setting address_retry_include_sender=false in the
2179 smtp transport.

2447PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2449 Unfortunately, if there is a major crisis, such as a disk failure,
2450 tcp-wrappers gives "deny", whereas what one would like would be some
2451 kind of temporary error. A kludge has been added to help with this.
2452 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2453 554 error is used if errno is still zero or contains ENOENT (which occurs
2454 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2455 451 error is used.

2491PH/01 The code for finding all the local interface addresses on a FreeBSD
2492 system running IPv6 was broken. This may well have applied to all BSD
2493 systems, as well as to others that have similar system calls. The broken
2494 code found IPv4 interfaces correctly, but gave incorrect values for the
2495 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2496 that it would not match correctly against @[] and not recognize the IPv6
2497 addresses as local.

2540 autoreply, Exim could try to deliver to a non-existent relative file

2561 changes:
2562
2563 (a) Failures to set uid/gid, the current directory, or a process leader
2564 in a subprocess such as that created by queryprogram now generate
2565 suitable debugging ouput when -d is set.
2566

2569 the subprocess without attempting to change uid/gid.

2575 additional section of a DNS packet that returns MX or SRV records.
2576 Instead, it always explicitly searches for A/AAAA records. This avoids
2577 major problems that occur when a DNS server includes only records of one
2578 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2579 fixed another bug: if SRV records were looked up and the corresponding
2580 address records were *not* found in the additional section, the port
2581 values from the SRV records were lost.

2583PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2591PH/19 When calculating a retry time, Exim used to measure the "time since
2592 failure" by looking at the "first failed" field in the retry record. Now
2593 it does not use this if it is later than than the arrival time of the
2594 message. Instead it uses the arrival time. This makes for better
2595 behaviour in cases where some deliveries succeed, thus re-setting the
2596 "first failed" field. An example is a quota failure for a huge message
2597 when small messages continue to be delivered. Without this change, the
2598 "time since failure" will always be short, possible causing more frequent
2599 delivery attempts for the huge message than are intended.

2696PH/42 The content-scanning code uses fopen() to create files in which to put

2699 files with open(), and sets the required mode explicitly. Thus, these
2700 files were ending up world-writeable. This was not a big issue, because,
2701 being within the spool directory, they were not world-accessible. I have
2702 created a function called modefopen, which takes an additional mode
2703 argument. It sets umask(777), creates the file, chmods it to the required
2704 mode, then resets the umask. All the relevant calls to fopen() in the

2731PH/50 When an Exim quota was set without a file count quota, and mailbox_size
2732 was also set, the appendfile transport was unnecessarily scanning a
2733 directory of message files (e.g. for maildir delivery) to find the count
2734 of files (along with the size), even though it did not need this
2735 information. It now does the scan only if it needs to find either the

2740PH/52 Two bugs concerned with error handling when the smtp transport is
2741 used in LMTP mode:
2742
2743 (i) Exim was not creating retry information for temporary errors given
2744 for individual recipients after the DATA command when the smtp transport
2745 was used in LMTP mode. This meant that they could be retried too
2746 frequently, and not timed out correctly.
2747
2748 (ii) Exim was setting the flag that allows error details to be returned
2749 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2750 recipients that were returned after the DATA command.
2751
2752PH/53 This is related to PH/52, but is more general: for any failing address,
2753 when detailed error information was permitted to be returned to the
2754 sender, but the error was temporary, then after the final timeout, only
2755 "retry timeout exceeded" was returned. Now it returns the full error as
2756 well as "retry timeout exceeded".

PH
2826PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2827 function verify_get_ident() calls ip_connect() to connect a socket, but
2828 if the "connect()" function timed out, ip_connect() used to close the
2829 socket. However, verify_get_ident() also closes the socket later, and in
2830 between Exim writes to the log, which may get opened at this point. When
2831 the socket was closed in ip_connect(), the log could get the same file
2832 descriptor number as the socket. This naturally causes chaos. The fix is
2833 not to close the socket in ip_connect(); the socket should be closed by
2834 the function that creates it. There was only one place in the code where
2835 this was missing, in the iplookup router, which I don't think anybody now
2836 uses, but I've fixed it anyway.

2859
2860 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2861 string.
2862
2863 (3) Reset the variables that are obtained from the first argument of
2864 ${prvscheck and used in the second argument before leaving the code,
2865 because their memory is reclaimed, so using them afterwards may do
2866 silly things.
2867
2868 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2869 one (it's much easier than Tom thought :-).
2870
2871 (5) Because of (4), we can now allow for the use of $prvscheck_result

2887 may be more than one such address. If so, they are comma-separated, like

PH
2892PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2893 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2894 not being looked up in the rDNS to get a host name, Exim was showing the
2895 IP address twice in Received: lines, even though the IP addresses were
2896 identical. For example:
2897
2898 Received: from [1.2.3.4] (helo=[1.2.3.4])
2899
2900 However, if the real host name was known, it was omitting the HELO data
2901 if it matched the actual IP address. This has been tidied up so that it
2902 doesn't show the same IP address twice.

2928PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2929 Electronic Mail") by including:
2930
2931 Auto-submitted: auto-generated
2932
2933 in the messages that it generates (bounce messages and others, such as
2934 warnings). In the case of bounce messages for non-SMTP mesages, there was
2935 also a typo: it was using "Auto_submitted" (underscore instead of
2936 hyphen). Since every message generated by Exim is necessarily in response
2937 to another message, thes have all been changed to:
2938
2939 Auto-Submitted: auto-replied
2940
2941 in accordance with these statements in the RFC:
2942
2943 The auto-replied keyword:
2944
2945 - SHOULD be used on messages sent in direct response to another
2946 message by an automatic process,
2947
2948 - MUST NOT be used on manually-generated messages,
2949
2950 - MAY be used on Delivery Status Notifications (DSNs) and Message
2951 Disposition Notifications (MDNs),

2991PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2992 canonical form (as documented). However, after a host name lookup from
2993 the IP address, check_host() was doing a simple string comparison with
2994 addresses acquired from the DNS when checking that the found name did
2995 have the original IP as one of its addresses. Since any found IPv6
2996 addresses are likely to be in abbreviated form, the comparison could
2997 fail. Luckily, there already exists a function for doing the comparison
2998 by converting both addresses to binary, so now that is used instead of
2999 the text comparison.

3140PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3177PH/36 When a locally submitted message by a trusted user did not contain a
3178 From: header, and the sender address was obtained from -f or from an SMTP
3179 MAIL command, and the trusted user did not use -F to supply a sender
3180 name, $originator_name was incorrectly used when constructing a From:
3181 header. Furthermore, $originator_name was used for submission mode
3182 messages from external hosts without From: headers in a similar way,
3183 which is clearly wrong.

3296PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3297 with the definition in sysexits.h (which is #included earlier).
3298 Fortunately, Exim does not actually use EX_OK. The code used to try to
3299 preserve the sysexits.h value, by assumimg that macro definitions were
3300 scanned for macro replacements. I have been disabused of this notion,
3301 so now the code just undefines EX_OK before #including unistd.h.

3303PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3304 in the smtp transport. When a block could not be written in a single
3305 write() function, the timeout was being re-applied to each part-write.
3306 This seems wrong - if the receiver was accepting one byte at a time it
3307 would take for ever. The timeout is now adjusted when this happens. It
3308 doesn't have to be particularly precise.
