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.

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.

49JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may

51

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.

79JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
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.
89

JH
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.

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.

228Exim version 4.85
229-----------------
230TL/01 When running the test suite, the README says that variables such as
231 no_msglog_check are global and can be placed anywhere in a specific
232 test's script, however it was observed that placement needed to be near
233 the beginning for it to behave that way. Changed the runtest perl
234 script to read through the entire script once to detect and set these
235 variables, reset to the beginning of the script, and then run through
236 the script parsing/test process like normal.

263JH/05 Fix results-pipe from transport process. Several recipients, combined
264 with certificate use, exposed issues where response data items split
265 over buffer boundaries were not parsed properly. This eventually
266 resulted in duplicates being sent. This issue only became common enough
267 to notice due to the introduction of conection certificate information,
268 the item size being so much larger. Found and fixed by Wolfgang Breyha.

340TF/01 Correctly close the server side of TLS when forking for delivery.
341
342 When a message was received over SMTP with TLS, Exim failed to clear up
343 the incoming connection properly after forking off the child process to
344 deliver the message. In some situations the subsequent outgoing
345 delivery connection happened to have the same fd number as the incoming
346 connection previously had. Exim would try to use TLS and fail, logging
347 a "Bad file descriptor" error.

593TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
594
595 When a queue runner is handling a message, Exim first routes the
596 recipient addresses, during which it prunes them based on the retry
597 hints database. After that it attempts to deliver the message to
598 any remaining recipients. It then updates the hints database using
599 the retry rules.
600
601 So if a recipient address works intermittently, it can get repeatedly
602 deferred at routing time. The retry hints record remains fresh so the
603 address never reaches the final cutoff time.
604
605 This is a fairly common occurrence when a user is bumping up against
606 their storage quota. Exim had some logic in its local delivery code
607 to deal with this. However it did not apply to per-recipient defers
608 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
609
1ddeb334
TF
610 This change adds a proper retry rule check during routing so that the
611 final cutoff time is checked against the message's age. We only do
612 this check if there is an address retry record and there is not a
613 domain retry record; this implies that previous attempts to handle
614 the address had the retry_use_local_parts option turned on. We use
615 this as an approximation for the destination being like a local
616 delivery, as in LMTP.
67bd1ab3
TF
617
618 I suspect this new check makes the old local delivery cutoff check
619 redundant, but I have not verified this so I left the code in place.

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

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

TF
941TF/03 Make the exiwhat support code safe for signals. Previously Exim might
942 lock up or crash if it happened to be inside a call to libc when it
943 got a SIGUSR1 from exiwhat.
944
945 The SIGUSR1 handler appends the current process status to the process
946 log which is later printed by exiwhat. It used to use the general
947 purpose logging code to do this, but several functions it calls are
948 not safe for signals.
949
950 The new output code in the SIGUSR1 handler is specific to the process
951 log, and simple enough that it's easy to inspect for signal safety.
952 Removing some special cases also simplifies the general logging code.
953 Removing the spurious timestamps from the process log simplifies
954 exiwhat.
955
c99ce5c9
TF
956TF/04 Improved ratelimit ACL condition.
957
958 The /noupdate option has been deprecated in favour of /readonly which
959 has clearer semantics. The /leaky, /strict, and /readonly update modes
960 are mutually exclusive. The update mode is no longer included in the
961 database key; it just determines when the database is updated. (This
962 means that when you upgrde Exim will forget old rate measurements.)
963
964 Exim now checks that the per_* options are used with an update mode that
965 makes sense for the current ACL. For example, when Exim is processing a
966 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
967 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
968 must specify per_mail/readonly. If you omit the update mode it defaults to
969 /leaky where that makes sense (as before) or /readonly where required.
970
971 The /noupdate option is now undocumented but still supported for
972 backwards compatibility. It is equivalent to /readonly except that in
973 ACLs where /readonly is required you may specify /leaky/noupdate or
974 /strict/noupdate which are treated the same as /readonly.
975
976 A useful new feature is the /count= option. This is a generalization
977 of the per_byte option, so that you can measure the throughput of other
978 aggregate values. For example, the per_byte option is now equivalent
979 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
980
981 The per_rcpt option has been generalized using the /count= mechanism
982 (though it's more complicated than the per_byte equivalence). When it is
983 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
984 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
985 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
986 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
987 Note that using per_rcpt with a non-readonly update mode in more than
988 one ACL will cause the recipients to be double-counted. (The per_mail
989 and per_byte options don't have this problem.)
990
991 The handling of very low rates has changed slightly. If the computed rate
992 is less than the event's count (usually one) then this event is the first
993 after a long gap. In this case the rate is set to the same as this event's
994 count, so that the first message of a spam run is counted properly.
995
996 The major new feature is a mechanism for counting the rate of unique
997 events. The new per_addr option counts the number of different
998 recipients that someone has sent messages to in the last time period. It
999 behaves like per_rcpt if all the recipient addresses are different, but
1000 duplicate recipient addresses do not increase the measured rate. Like
1001 the /count= option this is a general mechanism, so the per_addr option
1002 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1003 example, measure the rate that a client uses different sender addresses
1004 with the options per_mail/unique=$sender_address. There are further
1005 details in the main documentation.

1216 If dropping privileges for untrusted macros, we disabled normal logging
1217 on the basis that it would fail; for the Exim run-time user, this is not
1218 the case, and it resulted in successful deliveries going unlogged.

1577PH/01 Another patch from the Sieve maintainer.
1578
6a3bceb1
PH
1579PH/02 When an IPv6 address is converted to a string for single-key lookup
1580 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1581 dots are used instead of colons so that keys in lsearch files need not
1582 contain colons. This was done some time before quoting was made available
1583 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1584 (notated using the quote facility) so as to distinguish them from IPv4
1585 keys. This meant that lookups for IP addresses in host lists did not work
1586 for iplsearch lookups.
1587
1588 This has been fixed by arranging for IPv6 addresses to be expressed with
1589 colons if the lookup type is iplsearch. This is not incompatible, because
1590 previously such lookups could never work.
1591
1592 The situation is now rather anomolous, since one *can* have colons in
1593 ordinary lsearch keys. However, making the change in all cases is
1594 incompatible and would probably break a number of configurations.

1599MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1600 conversion specification without a maximum field width, thereby enabling
1601 a rogue spamd server to cause a buffer overflow. While nobody in their
1602 right mind would setup Exim to query an untrusted spamd server, an
1603 attacker that gains access to a server running spamd could potentially
1604 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1609MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1610 a directory entry by the name of the lookup key. Previously, if a
1611 symlink pointed to a non-existing file or a file in a directory that
1612 Exim lacked permissions to read, a lookup for a key matching that
1613 symlink would fail. Now it is enough that a matching directory entry
1614 exists, symlink or not. (Bugzilla 503.)

PH
1797PH/29 SMTP synchronization checks are implemented when a command is read -
1798 there is a check that no more input is waiting when there shouldn't be
1799 any. However, for some commands, a delay in an ACL can mean that it is
1800 some time before the response is written. In this time, more input might
1801 arrive, invalidly. So now there are extra checks after an ACL has run for
1802 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1803 pipelining has not been advertised.

PH
1815PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1816 Exim which did not show up earlier: it was assuming that a call to
1817 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1818 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1819 was a macro that became an assignment, so it seemed to work. This has
1820 changed to a proper function call with a void return, hence the compile
1821 error. Exim's code has been fixed.

1852 started the daemon, but after a SIGHUP it used the Exim user (because it

1859 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1877 the response to the final '.' that terminates a message, but only in the
1878 case where the client has not sent further data following the '.'
1879 (unfortunately, this is allowed). However, in many cases there won't be
1880 any further data because there won't be any more messages to send. A call
1881 to select() can be used: if it shows that the input is "ready", there is
1882 either input waiting, or the socket has been closed. An attempt to read
1883 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1884 would have sent an OK response which the client would never have see.

1895PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1896 fixed by 4.65/MH/01 (is this a record?) are fixed:
1897
1898 (i) An empty string was always treated as zero by the numeric comparison
1899 operators. This behaviour has been restored.
1900
1901 (ii) It is documented that the numeric comparison operators always treat
1902 their arguments as decimal numbers. This was broken in that numbers
1903 starting with 0 were being interpreted as octal.
1904
1905 While fixing these problems I realized that there was another issue that
1906 hadn't been noticed. Values of message_size_limit (both the global option
1907 and the transport option) were treated as octal if they started with 0.
1908 The documentation was vague. These values are now always treated as
1909 decimal, and I will make that clear in the documentation.

1956 verification with use_sender or use_postmaster set, because in that case
1957 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1958 case of MAIL FROM:<> rejection from other early rejections (e.g.
1959 rejection of HELO). When verifying a recipient using a non-null MAIL
1960 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1961 Whatever the result of the callout, the value of the domain cache is
1962 left unchanged (for any other kind of callout, getting as far as trying
1963 RCPT means that the domain itself is ok).

1997PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1998 hostname. This is wrong, because it relates to the incoming message (and
1999 probably the interface on which it is arriving) and not to the outgoing
2000 callout (which could be using a different interface). This has been
2001 changed to use the value of the helo_data option from the smtp transport
2002 instead - this is what is used when a message is actually being sent. If
2003 there is no remote transport (possible with a router that sets up host
2004 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2008 (a) The code assumed that strncpy() returns a negative number on buffer
2009 overflow, which isn't the case. Replaced with Exim's string_format()
2010 function.
2011 (b) There were several signed/unsigned issues. I just did the minimum
2012 hacking in of casts. There is scope for a larger refactoring.
2013 (c) The code used strcasecmp() which is not a standard C function.
2014 Replaced with Exim's strcmpic() function.
2015 (d) The code set only $1; it now sets $auth1 as well.
2016 (e) A simple test gave the error "authentication client didn't specify
2017 service in request". It would seem that Dovecot has changed its
2018 interface. Fortunately there's a specification; I followed it and
2019 changed what the client sends and it appears to be working now.

2025 address A is aliased to B and C, where B exists and C does not. Without
2026 -v the output is "A verified" because verification stops after a
2027 successful redirection if more than one address is generated. However,
2028 with -v the child addresses are also verified. Exim was outputting "A
2029 failed to verify" and then showing the successful verification for C,
2030 with its parentage. It now outputs "B failed to verify", showing B's
2031 parentage before showing the successful verification of C.

PH
2037PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2038 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2039 they consult the DNS. I had assumed they would set it the way they
2040 wanted; and indeed my experiments on Linux seem to show that in some
2041 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2042 To be on the safe side, however, I have now made the interface to
2043 host_find_byname() similar to host_find_bydns(), with an argument
2044 containing the DNS resolver options. The host_find_byname() function now
2045 sets these options at its start, just as host_find_bydns() does. The smtp
2046 transport options dns_qualify_single and dns_search_parents are passed to
2047 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2048 of host_find_byname() use the default settings of RES_DEFNAMES
2049 (qualify_single) but not RES_DNSRCH (search_parents).

2051PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2052 spool_read_header() do less string testing, by means of a preliminary
2053 switch on the second character of optional "-foo" lines. (This is
2054 overdue, caused by the large number of possibilities that now exist.
2055 Originally there were few.) While I was there, I also converted the
2056 str(n)cmp tests so they don't re-test the leading "-" and the first
2057 character, in the hope this might squeeze out yet more improvement.

2059PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2060 flag allowing group syntax was set by the header_syntax check but not
2061 turned off, possible causing trouble later; (2) The flag was not being
2062 set at all for the header_verify test, causing "group"-style headers to
2063 be rejected. I have now set it in this case, and also caused header_
2064 verify to ignore an empty address taken from a group. While doing this, I
2065 came across some other cases where the code for allowing group syntax
2066 while scanning a header line wasn't quite right (mostly, not resetting
2067 the flag correctly in the right place). These bugs could have caused
2068 trouble for malformed header lines. I hope it is now all correct.

2070PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2073 but it didn't always do it. This confused somebody who was copying the
2074 code for some other use. I have removed all the tests.

PH
2076PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2077 feature that was used to support insecure browsers during the U.S. crypto
2078 embargo. It requires special client support, and Exim is probably the
2079 only MTA that supported it -- and would never use it because real RSA is
2080 always available. This code has been removed, because it had the bad
2081 effect of slowing Exim down by computing (never used) parameters for the
2082 RSA_EXPORT functionality.

2087 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2088 if the connection is using TLS or if the remote IP is the same as the
2089 local IP, and the "valid-client-cert option" if a client certificate has
2090 been verified.

2121
2122PH/30 Exim was sometimes attempting to deliver messages that had suffered
2123 address errors (4xx response to RCPT) over the same connection as other
2124 messages routed to the same hosts. Such deliveries are always "forced",
2125 so retry times are not inspected. This resulted in far too many retries
2126 for the affected addresses. The effect occurred only when there were more
2127 hosts than the hosts_max_try setting in the smtp transport when it had
2128 the 4xx errors. Those hosts that it had tried were not added to the list
2129 of hosts for which the message was waiting, so if all were tried, there
2130 was no problem. Two fixes have been applied:
2131
2132 (i) If there are any address or message errors in an SMTP delivery, none
2133 of the hosts (tried or untried) are now added to the list of hosts
2134 for which the message is waiting, so the message should not be a
2135 candidate for sending over the same connection that was used for a
2136 successful delivery of some other message. This seems entirely
2137 reasonable: after all the message is NOT "waiting for some host".
2138 This is so "obvious" that I'm not sure why it wasn't done
2139 previously. Hope I haven't missed anything, but it can't do any
2140 harm, as the worst effect is to miss an optimization.
2141
2142 (ii) If, despite (i), such a delivery is accidentally attempted, the
2143 routing retry time is respected, so at least it doesn't keep
2144 hammering the server.

2159PH/35 The error "getsockname() failed: connection reset by peer" was being
2160 written to the panic log as well as the main log, but it isn't really

2162 removed the panic log writing for the ECONNRESET error when getsockname()
2163 fails.
2164
48c7f9e2
PH
2165PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2166 runs only) independently of the message's sender address. This meant
2167 that, if the 4xx error was in fact related to the sender, a different
2168 message to the same recipient with a different sender could confuse
2169 things. In particualar, this can happen when sending to a greylisting
2170 server, but other circumstances could also provoke similar problems.
2171 I have changed the default so that the retry time for these errors is now
2172 based a combination of the sender and recipient addresses. This change
2173 can be overridden by setting address_retry_include_sender=false in the
2174 smtp transport.

2442PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2444 Unfortunately, if there is a major crisis, such as a disk failure,
2445 tcp-wrappers gives "deny", whereas what one would like would be some
2446 kind of temporary error. A kludge has been added to help with this.
2447 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2448 554 error is used if errno is still zero or contains ENOENT (which occurs
2449 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2450 451 error is used.

2486PH/01 The code for finding all the local interface addresses on a FreeBSD
2487 system running IPv6 was broken. This may well have applied to all BSD
2488 systems, as well as to others that have similar system calls. The broken
2489 code found IPv4 interfaces correctly, but gave incorrect values for the
2490 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2491 that it would not match correctly against @[] and not recognize the IPv6
2492 addresses as local.

2535 autoreply, Exim could try to deliver to a non-existent relative file

2558 (a) Failures to set uid/gid, the current directory, or a process leader
2559 in a subprocess such as that created by queryprogram now generate
2560 suitable debugging ouput when -d is set.

2570 additional section of a DNS packet that returns MX or SRV records.
2571 Instead, it always explicitly searches for A/AAAA records. This avoids
2572 major problems that occur when a DNS server includes only records of one
2573 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2574 fixed another bug: if SRV records were looked up and the corresponding
2575 address records were *not* found in the additional section, the port
2576 values from the SRV records were lost.

2578PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2586PH/19 When calculating a retry time, Exim used to measure the "time since
2587 failure" by looking at the "first failed" field in the retry record. Now
2588 it does not use this if it is later than than the arrival time of the
2589 message. Instead it uses the arrival time. This makes for better
2590 behaviour in cases where some deliveries succeed, thus re-setting the
2591 "first failed" field. An example is a quota failure for a huge message
2592 when small messages continue to be delivered. Without this change, the
2593 "time since failure" will always be short, possible causing more frequent
2594 delivery attempts for the huge message than are intended.

2691PH/42 The content-scanning code uses fopen() to create files in which to put

2694 files with open(), and sets the required mode explicitly. Thus, these
2695 files were ending up world-writeable. This was not a big issue, because,
2696 being within the spool directory, they were not world-accessible. I have
2697 created a function called modefopen, which takes an additional mode
2698 argument. It sets umask(777), creates the file, chmods it to the required
2699 mode, then resets the umask. All the relevant calls to fopen() in the

2726PH/50 When an Exim quota was set without a file count quota, and mailbox_size
2727 was also set, the appendfile transport was unnecessarily scanning a
2728 directory of message files (e.g. for maildir delivery) to find the count
2729 of files (along with the size), even though it did not need this
2730 information. It now does the scan only if it needs to find either the
2731 size of the count of files.

PH
2735PH/52 Two bugs concerned with error handling when the smtp transport is
2736 used in LMTP mode:
2737
2738 (i) Exim was not creating retry information for temporary errors given
2739 for individual recipients after the DATA command when the smtp transport
2740 was used in LMTP mode. This meant that they could be retried too
2741 frequently, and not timed out correctly.
2742
2743 (ii) Exim was setting the flag that allows error details to be returned
2744 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2745 recipients that were returned after the DATA command.
2746
2747PH/53 This is related to PH/52, but is more general: for any failing address,
2748 when detailed error information was permitted to be returned to the
2749 sender, but the error was temporary, then after the final timeout, only
2750 "retry timeout exceeded" was returned. Now it returns the full error as
2751 well as "retry timeout exceeded".

2807PH/68 The bounce_return_message and bounce_return_body options were not being

2809 In particular, this applied to messages rejected by the ACL. This bug has
2810 been fixed. However, if bounce_return_message is true and bounce_return_
2811 body is false, the headers that are returned for a non-SMTP message
2812 include only those that have been read before the error was detected.

PH
2821PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2822 function verify_get_ident() calls ip_connect() to connect a socket, but
2823 if the "connect()" function timed out, ip_connect() used to close the
2824 socket. However, verify_get_ident() also closes the socket later, and in
2825 between Exim writes to the log, which may get opened at this point. When
2826 the socket was closed in ip_connect(), the log could get the same file
2827 descriptor number as the socket. This naturally causes chaos. The fix is
2828 not to close the socket in ip_connect(); the socket should be closed by
2829 the function that creates it. There was only one place in the code where
2830 this was missing, in the iplookup router, which I don't think anybody now
2831 uses, but I've fixed it anyway.

2850PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2851
2852 (1) Generate an error if the third argument for the ${prvs expansion is
2853 not a single digit.
2854
2855 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2856 string.
2857
2858 (3) Reset the variables that are obtained from the first argument of
2859 ${prvscheck and used in the second argument before leaving the code,
2860 because their memory is reclaimed, so using them afterwards may do
2861 silly things.
2862
2863 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2864 one (it's much easier than Tom thought :-).
2865
2866 (5) Because of (4), we can now allow for the use of $prvscheck_result
2867 inside the third argument.

2878
2879 => >A.N.Other <ano@some.domain> <original@ddress> ...
2880
2881 This has been changed so that it extracts the operative address. There
2882 may be more than one such address. If so, they are comma-separated, like
2883 this:
2884
2885 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2887PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2888 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2889 not being looked up in the rDNS to get a host name, Exim was showing the
2890 IP address twice in Received: lines, even though the IP addresses were
2891 identical. For example:
2892
2893 Received: from [1.2.3.4] (helo=[1.2.3.4])
2894
2895 However, if the real host name was known, it was omitting the HELO data
2896 if it matched the actual IP address. This has been tidied up so that it
2897 doesn't show the same IP address twice.

2899PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2923PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2924 Electronic Mail") by including:
2925
2926 Auto-submitted: auto-generated
2927
2928 in the messages that it generates (bounce messages and others, such as
2929 warnings). In the case of bounce messages for non-SMTP mesages, there was
2930 also a typo: it was using "Auto_submitted" (underscore instead of
2931 hyphen). Since every message generated by Exim is necessarily in response
2932 to another message, thes have all been changed to:
2933
2934 Auto-Submitted: auto-replied
2935
2936 in accordance with these statements in the RFC:
2937
2938 The auto-replied keyword:
2939
2940 - SHOULD be used on messages sent in direct response to another
2941 message by an automatic process,
2942
2943 - MUST NOT be used on manually-generated messages,
2944
2945 - MAY be used on Delivery Status Notifications (DSNs) and Message
2946 Disposition Notifications (MDNs),
2947
2948 - MUST NOT be used on messages generated by automatic or periodic
2949 processes, except for messages which are automatic responses to
2950 other messages.

2974 nobody wrote the draft yet. This extension is currently #undef'ed, thus

PH
2986PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2987 canonical form (as documented). However, after a host name lookup from
2988 the IP address, check_host() was doing a simple string comparison with
2989 addresses acquired from the DNS when checking that the found name did
2990 have the original IP as one of its addresses. Since any found IPv6
2991 addresses are likely to be in abbreviated form, the comparison could
2992 fail. Luckily, there already exists a function for doing the comparison
2993 by converting both addresses to binary, so now that is used instead of
2994 the text comparison.
2995
96776534
PH
2996PH/20 There was another similar case to PH/19, when a complete host name was
2997 given in a host list; looking up its IP address could give an abbreviated

2999 The same fix has been applied.

3137 client host address. Thus, it would show the EHLO address in Received:
3138 header lines when this was not necessary.

3172PH/36 When a locally submitted message by a trusted user did not contain a
3173 From: header, and the sender address was obtained from -f or from an SMTP
3174 MAIL command, and the trusted user did not use -F to supply a sender
3175 name, $originator_name was incorrectly used when constructing a From:
3176 header. Furthermore, $originator_name was used for submission mode
3177 messages from external hosts without From: headers in a similar way,
3178 which is clearly wrong.

3291PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3292 with the definition in sysexits.h (which is #included earlier).
3293 Fortunately, Exim does not actually use EX_OK. The code used to try to
3294 preserve the sysexits.h value, by assumimg that macro definitions were
3295 scanned for macro replacements. I have been disabused of this notion,
3296 so now the code just undefines EX_OK before #including unistd.h.

3298PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3299 in the smtp transport. When a block could not be written in a single
3300 write() function, the timeout was being re-applied to each part-write.
3301 This seems wrong - if the receiver was accepting one byte at a time it
3302 would take for ever. The timeout is now adjusted when this happens. It
3303 doesn't have to be particularly precise.
