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.

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.

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

200Exim version 4.85
201-----------------
202TL/01 When running the test suite, the README says that variables such as
203 no_msglog_check are global and can be placed anywhere in a specific
204 test's script, however it was observed that placement needed to be near
205 the beginning for it to behave that way. Changed the runtest perl
206 script to read through the entire script once to detect and set these
207 variables, reset to the beginning of the script, and then run through
208 the script parsing/test process like normal.

235JH/05 Fix results-pipe from transport process. Several recipients, combined
236 with certificate use, exposed issues where response data items split
237 over buffer boundaries were not parsed properly. This eventually
238 resulted in duplicates being sent. This issue only became common enough
239 to notice due to the introduction of conection certificate information,
240 the item size being so much larger. Found and fixed by Wolfgang Breyha.

315 the incoming connection properly after forking off the child process to
316 deliver the message. In some situations the subsequent outgoing
317 delivery connection happened to have the same fd number as the incoming

565TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
566
567 When a queue runner is handling a message, Exim first routes the
568 recipient addresses, during which it prunes them based on the retry
569 hints database. After that it attempts to deliver the message to
570 any remaining recipients. It then updates the hints database using
571 the retry rules.
572
573 So if a recipient address works intermittently, it can get repeatedly
574 deferred at routing time. The retry hints record remains fresh so the
575 address never reaches the final cutoff time.
576
577 This is a fairly common occurrence when a user is bumping up against
578 their storage quota. Exim had some logic in its local delivery code
579 to deal with this. However it did not apply to per-recipient defers
580 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
581
1ddeb334
TF
582 This change adds a proper retry rule check during routing so that the
583 final cutoff time is checked against the message's age. We only do
584 this check if there is an address retry record and there is not a
585 domain retry record; this implies that previous attempts to handle
586 the address had the retry_use_local_parts option turned on. We use
587 this as an approximation for the destination being like a local
588 delivery, as in LMTP.
67bd1ab3
TF
589
590 I suspect this new check makes the old local delivery cutoff check
591 redundant, but I have not verified this so I left the code in place.

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

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

913TF/03 Make the exiwhat support code safe for signals. Previously Exim might
914 lock up or crash if it happened to be inside a call to libc when it
915 got a SIGUSR1 from exiwhat.
916
917 The SIGUSR1 handler appends the current process status to the process
918 log which is later printed by exiwhat. It used to use the general
919 purpose logging code to do this, but several functions it calls are
920 not safe for signals.
921
922 The new output code in the SIGUSR1 handler is specific to the process
923 log, and simple enough that it's easy to inspect for signal safety.
924 Removing some special cases also simplifies the general logging code.
925 Removing the spurious timestamps from the process log simplifies
926 exiwhat.
927
c99ce5c9
TF
928TF/04 Improved ratelimit ACL condition.
929
930 The /noupdate option has been deprecated in favour of /readonly which
931 has clearer semantics. The /leaky, /strict, and /readonly update modes
932 are mutually exclusive. The update mode is no longer included in the
933 database key; it just determines when the database is updated. (This
934 means that when you upgrde Exim will forget old rate measurements.)
935
936 Exim now checks that the per_* options are used with an update mode that
937 makes sense for the current ACL. For example, when Exim is processing a
938 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
939 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
940 must specify per_mail/readonly. If you omit the update mode it defaults to
941 /leaky where that makes sense (as before) or /readonly where required.
942
943 The /noupdate option is now undocumented but still supported for
944 backwards compatibility. It is equivalent to /readonly except that in
945 ACLs where /readonly is required you may specify /leaky/noupdate or
946 /strict/noupdate which are treated the same as /readonly.
947
948 A useful new feature is the /count= option. This is a generalization
949 of the per_byte option, so that you can measure the throughput of other
950 aggregate values. For example, the per_byte option is now equivalent
951 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
952
953 The per_rcpt option has been generalized using the /count= mechanism
954 (though it's more complicated than the per_byte equivalence). When it is
955 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
956 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
957 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
958 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
959 Note that using per_rcpt with a non-readonly update mode in more than
960 one ACL will cause the recipients to be double-counted. (The per_mail
961 and per_byte options don't have this problem.)
962
963 The handling of very low rates has changed slightly. If the computed rate
964 is less than the event's count (usually one) then this event is the first
965 after a long gap. In this case the rate is set to the same as this event's
966 count, so that the first message of a spam run is counted properly.
967
968 The major new feature is a mechanism for counting the rate of unique
969 events. The new per_addr option counts the number of different
970 recipients that someone has sent messages to in the last time period. It
971 behaves like per_rcpt if all the recipient addresses are different, but
972 duplicate recipient addresses do not increase the measured rate. Like
973 the /count= option this is a general mechanism, so the per_addr option
974 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
975 example, measure the rate that a client uses different sender addresses
976 with the options per_mail/unique=$sender_address. There are further
977 details in the main documentation.

1528 were called 'true' and it seems that C99 defines that as a reserved

1530 not include C99-style headers which use bools without triggering

1549PH/01 Another patch from the Sieve maintainer.
1550
6a3bceb1
PH
1551PH/02 When an IPv6 address is converted to a string for single-key lookup
1552 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1553 dots are used instead of colons so that keys in lsearch files need not
1554 contain colons. This was done some time before quoting was made available
1555 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1556 (notated using the quote facility) so as to distinguish them from IPv4
1557 keys. This meant that lookups for IP addresses in host lists did not work
1558 for iplsearch lookups.
1559
1560 This has been fixed by arranging for IPv6 addresses to be expressed with
1561 colons if the lookup type is iplsearch. This is not incompatible, because
1562 previously such lookups could never work.
1563
1564 The situation is now rather anomolous, since one *can* have colons in
1565 ordinary lsearch keys. However, making the change in all cases is
1566 incompatible and would probably break a number of configurations.

MH
1571MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1572 conversion specification without a maximum field width, thereby enabling
1573 a rogue spamd server to cause a buffer overflow. While nobody in their
1574 right mind would setup Exim to query an untrusted spamd server, an
1575 attacker that gains access to a server running spamd could potentially
1576 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1581MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1582 a directory entry by the name of the lookup key. Previously, if a
1583 symlink pointed to a non-existing file or a file in a directory that
1584 Exim lacked permissions to read, a lookup for a key matching that
1585 symlink would fail. Now it is enough that a matching directory entry
1586 exists, symlink or not. (Bugzilla 503.)

1659PH/02 In an ACL statement such as

1663 if a client was not listed at all, or was listed with a value other than
1664 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1665 the condition was not true (as it should be), so access was not denied.
1666 The bug was that the ! inversion was incorrectly passed on to the second
1667 item. This has been fixed.

1691PH/07 There was a bug in the dovecot authenticator such that the value of

1700PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1701 run for batched SMTP input. It is now run at the start of every message
1702 in the batch. While fixing this I discovered that the process information
1703 (output by running exiwhat) was not always getting set for -bs and -bS

1764PH/28 The $smtp_command and $smtp_command_argument variables were not correct

a14e5636
PH
1769PH/29 SMTP synchronization checks are implemented when a command is read -
1770 there is a check that no more input is waiting when there shouldn't be
1771 any. However, for some commands, a delay in an ACL can mean that it is
1772 some time before the response is written. In this time, more input might
1773 arrive, invalidly. So now there are extra checks after an ACL has run for
1774 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1775 pipelining has not been advertised.

PH
1787PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1788 Exim which did not show up earlier: it was assuming that a call to
1789 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1790 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1791 was a macro that became an assignment, so it seemed to work. This has
1792 changed to a proper function call with a void return, hence the compile
1793 error. Exim's code has been fixed.

1821PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1822 whoever called Exim into the -H file. In the case of the daemon it was
1823 behaving confusingly. When first started, it used values for whoever
1824 started the daemon, but after a SIGHUP it used the Exim user (because it
1825 calls itself on a restart). I have changed the code so that it now always
1826 uses the Exim user.

1830 sender address), and a DATA command is nevertheless sent (as can happen
1831 with PIPELINING or a stupid MUA), the error message that was given to the
1832 RCPT commands is included in the rejection of the DATA command. This is
1833 intended to be helpful for MUAs that show only the final error to their

PH
1849 the response to the final '.' that terminates a message, but only in the
1850 case where the client has not sent further data following the '.'
1851 (unfortunately, this is allowed). However, in many cases there won't be
1852 any further data because there won't be any more messages to send. A call
1853 to select() can be used: if it shows that the input is "ready", there is
1854 either input waiting, or the socket has been closed. An attempt to read
1855 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1856 would have sent an OK response which the client would never have see.

1866
1867PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1868 fixed by 4.65/MH/01 (is this a record?) are fixed:
1869
1870 (i) An empty string was always treated as zero by the numeric comparison
1871 operators. This behaviour has been restored.
1872
1873 (ii) It is documented that the numeric comparison operators always treat
1874 their arguments as decimal numbers. This was broken in that numbers
1875 starting with 0 were being interpreted as octal.
1876
1877 While fixing these problems I realized that there was another issue that
1878 hadn't been noticed. Values of message_size_limit (both the global option
1879 and the transport option) were treated as octal if they started with 0.
1880 The documentation was vague. These values are now always treated as
1881 decimal, and I will make that clear in the documentation.

1897 is held in a short int, deliveries were likely to be lost. As such a
1898 large number of recipients for a single message is ridiculous
1899 (performance will be very, very poor), I have chosen to impose a limit

1906TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1907 leftover -K file (the existence of which was triggered by #402).
1908 While we were at it, introduced process PID as part of the -K

1912TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1913 processing considerably. Previous code took too long for large mails,

1915
1916TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1917 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
1925PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1926 callout verification, Exim cached a "reject" for the entire domain. This
1927 is correct for most verifications, but it is not correct for a recipient
1928 verification with use_sender or use_postmaster set, because in that case
1929 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1930 case of MAIL FROM:<> rejection from other early rejections (e.g.
1931 rejection of HELO). When verifying a recipient using a non-null MAIL
1932 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1933 Whatever the result of the callout, the value of the domain cache is
1934 left unchanged (for any other kind of callout, getting as far as trying
1935 RCPT means that the domain itself is ok).

1969PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1970 hostname. This is wrong, because it relates to the incoming message (and
1971 probably the interface on which it is arriving) and not to the outgoing
1972 callout (which could be using a different interface). This has been
1973 changed to use the value of the helo_data option from the smtp transport
1974 instead - this is what is used when a message is actually being sent. If
1975 there is no remote transport (possible with a router that sets up host
1976 addresses), $smtp_active_hostname is used.

14aa5a05 1978PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1979 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1980 (a) The code assumed that strncpy() returns a negative number on buffer
1981 overflow, which isn't the case. Replaced with Exim's string_format()
1982 function.
1983 (b) There were several signed/unsigned issues. I just did the minimum
1984 hacking in of casts. There is scope for a larger refactoring.
1985 (c) The code used strcasecmp() which is not a standard C function.
1986 Replaced with Exim's strcmpic() function.
1987 (d) The code set only $1; it now sets $auth1 as well.
1988 (e) A simple test gave the error "authentication client didn't specify
1989 service in request". It would seem that Dovecot has changed its
1990 interface. Fortunately there's a specification; I followed it and
1991 changed what the client sends and it appears to be working now.

PH
1996PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1997 address A is aliased to B and C, where B exists and C does not. Without
1998 -v the output is "A verified" because verification stops after a
1999 successful redirection if more than one address is generated. However,
2000 with -v the child addresses are also verified. Exim was outputting "A
2001 failed to verify" and then showing the successful verification for C,
2002 with its parentage. It now outputs "B failed to verify", showing B's
2003 parentage before showing the successful verification of C.

2006 look up a TXT record in a specific list after matching in a combined

2008
322050c2
PH
2009PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2010 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2011 they consult the DNS. I had assumed they would set it the way they
2012 wanted; and indeed my experiments on Linux seem to show that in some
2013 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2014 To be on the safe side, however, I have now made the interface to
2015 host_find_byname() similar to host_find_bydns(), with an argument
2016 containing the DNS resolver options. The host_find_byname() function now
2017 sets these options at its start, just as host_find_bydns() does. The smtp
2018 transport options dns_qualify_single and dns_search_parents are passed to
2019 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2020 of host_find_byname() use the default settings of RES_DEFNAMES
2021 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2023PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2024 spool_read_header() do less string testing, by means of a preliminary
2025 switch on the second character of optional "-foo" lines. (This is
2026 overdue, caused by the large number of possibilities that now exist.
2027 Originally there were few.) While I was there, I also converted the
2028 str(n)cmp tests so they don't re-test the leading "-" and the first
2029 character, in the hope this might squeeze out yet more improvement.

PH
2031PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2032 flag allowing group syntax was set by the header_syntax check but not
2033 turned off, possible causing trouble later; (2) The flag was not being
2034 set at all for the header_verify test, causing "group"-style headers to
2035 be rejected. I have now set it in this case, and also caused header_
2036 verify to ignore an empty address taken from a group. While doing this, I
2037 came across some other cases where the code for allowing group syntax
2038 while scanning a header line wasn't quite right (mostly, not resetting
2039 the flag correctly in the right place). These bugs could have caused
2040 trouble for malformed header lines. I hope it is now all correct.
2041
602e59e5
PH
2042PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2043 with the "reply" argument non-NULL. The code, however (which originally
2044 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2045 but it didn't always do it. This confused somebody who was copying the
2046 code for some other use. I have removed all the tests.

PH
2048PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2049 feature that was used to support insecure browsers during the U.S. crypto
2050 embargo. It requires special client support, and Exim is probably the
2051 only MTA that supported it -- and would never use it because real RSA is
2052 always available. This code has been removed, because it had the bad
2053 effect of slowing Exim down by computing (never used) parameters for the
2054 RSA_EXPORT functionality.
2055
7befa435
PH
2056PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2057 authenticator to fail if there's a tab character in the incoming data
2058 (there should never be unless someone is messing about, as it's supposed
2059 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2060 if the connection is using TLS or if the remote IP is the same as the
2061 local IP, and the "valid-client-cert option" if a client certificate has
2062 been verified.

2093
2094PH/30 Exim was sometimes attempting to deliver messages that had suffered
2095 address errors (4xx response to RCPT) over the same connection as other
2096 messages routed to the same hosts. Such deliveries are always "forced",
2097 so retry times are not inspected. This resulted in far too many retries
2098 for the affected addresses. The effect occurred only when there were more
2099 hosts than the hosts_max_try setting in the smtp transport when it had
2100 the 4xx errors. Those hosts that it had tried were not added to the list
2101 of hosts for which the message was waiting, so if all were tried, there
2102 was no problem. Two fixes have been applied:
2103
2104 (i) If there are any address or message errors in an SMTP delivery, none
2105 of the hosts (tried or untried) are now added to the list of hosts
2106 for which the message is waiting, so the message should not be a
2107 candidate for sending over the same connection that was used for a
2108 successful delivery of some other message. This seems entirely
2109 reasonable: after all the message is NOT "waiting for some host".
2110 This is so "obvious" that I'm not sure why it wasn't done
2111 previously. Hope I haven't missed anything, but it can't do any
2112 harm, as the worst effect is to miss an optimization.
2113
2114 (ii) If, despite (i), such a delivery is accidentally attempted, the
2115 routing retry time is respected, so at least it doesn't keep
2116 hammering the server.

PH
2131PH/35 The error "getsockname() failed: connection reset by peer" was being
2132 written to the panic log as well as the main log, but it isn't really
2133 panic-worthy as it just means the connection died rather early on. I have
2134 removed the panic log writing for the ECONNRESET error when getsockname()
2135 fails.
2136
48c7f9e2
PH
2137PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2138 runs only) independently of the message's sender address. This meant
2139 that, if the 4xx error was in fact related to the sender, a different
2140 message to the same recipient with a different sender could confuse
2141 things. In particualar, this can happen when sending to a greylisting
2142 server, but other circumstances could also provoke similar problems.
2143 I have changed the default so that the retry time for these errors is now
2144 based a combination of the sender and recipient addresses. This change
2145 can be overridden by setting address_retry_include_sender=false in the
2146 smtp transport.

2414PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2415 "Deny" causes Exim to reject the incoming connection with a 554 error.
2416 Unfortunately, if there is a major crisis, such as a disk failure,
2417 tcp-wrappers gives "deny", whereas what one would like would be some
2418 kind of temporary error. A kludge has been added to help with this.
2419 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2420 554 error is used if errno is still zero or contains ENOENT (which occurs
2421 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2422 451 error is used.

2458PH/01 The code for finding all the local interface addresses on a FreeBSD
2459 system running IPv6 was broken. This may well have applied to all BSD
2460 systems, as well as to others that have similar system calls. The broken
2461 code found IPv4 interfaces correctly, but gave incorrect values for the
2462 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2463 that it would not match correctly against @[] and not recognize the IPv6
2464 addresses as local.

2507 autoreply, Exim could try to deliver to a non-existent relative file

2543 Instead, it always explicitly searches for A/AAAA records. This avoids
2544 major problems that occur when a DNS server includes only records of one
2545 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2546 fixed another bug: if SRV records were looked up and the corresponding
2547 address records were *not* found in the additional section, the port
2548 values from the SRV records were lost.

2550PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2558PH/19 When calculating a retry time, Exim used to measure the "time since
2559 failure" by looking at the "first failed" field in the retry record. Now
2560 it does not use this if it is later than than the arrival time of the
2561 message. Instead it uses the arrival time. This makes for better
2562 behaviour in cases where some deliveries succeed, thus re-setting the
2563 "first failed" field. An example is a quota failure for a huge message
2564 when small messages continue to be delivered. Without this change, the
2565 "time since failure" will always be short, possible causing more frequent
2566 delivery attempts for the huge message than are intended.

2663PH/42 The content-scanning code uses fopen() to create files in which to put
2664 message data. Previously it was not paying any attention to the mode of
2665 the files. Exim runs with umask(0) because the rest of the code creates
2666 files with open(), and sets the required mode explicitly. Thus, these
2667 files were ending up world-writeable. This was not a big issue, because,
2668 being within the spool directory, they were not world-accessible. I have
2669 created a function called modefopen, which takes an additional mode
2670 argument. It sets umask(777), creates the file, chmods it to the required
2671 mode, then resets the umask. All the relevant calls to fopen() in the

2712 was used in LMTP mode. This meant that they could be retried too
2713 frequently, and not timed out correctly.
2714
2715 (ii) Exim was setting the flag that allows error details to be returned
2716 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2717 recipients that were returned after the DATA command.
2718
2719PH/53 This is related to PH/52, but is more general: for any failing address,
2720 when detailed error information was permitted to be returned to the

2793PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2794 function verify_get_ident() calls ip_connect() to connect a socket, but
2795 if the "connect()" function timed out, ip_connect() used to close the
2796 socket. However, verify_get_ident() also closes the socket later, and in
2797 between Exim writes to the log, which may get opened at this point. When
2798 the socket was closed in ip_connect(), the log could get the same file
2799 descriptor number as the socket. This naturally causes chaos. The fix is
2800 not to close the socket in ip_connect(); the socket should be closed by
2801 the function that creates it. There was only one place in the code where
2802 this was missing, in the iplookup router, which I don't think anybody now
2803 uses, but I've fixed it anyway.

2826
2827 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2828 string.
2829
2830 (3) Reset the variables that are obtained from the first argument of
2831 ${prvscheck and used in the second argument before leaving the code,
2832 because their memory is reclaimed, so using them afterwards may do
2833 silly things.
2834
2835 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2836 one (it's much easier than Tom thought :-).
2837

2859PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2860 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2861 not being looked up in the rDNS to get a host name, Exim was showing the
2862 IP address twice in Received: lines, even though the IP addresses were
2863 identical. For example:
2864
2865 Received: from [1.2.3.4] (helo=[1.2.3.4])
2866
2867 However, if the real host name was known, it was omitting the HELO data
2868 if it matched the actual IP address. This has been tidied up so that it
2869 doesn't show the same IP address twice.

2895PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2897
2898 Auto-submitted: auto-generated
2899
2900 in the messages that it generates (bounce messages and others, such as
2901 warnings). In the case of bounce messages for non-SMTP mesages, there was
2902 also a typo: it was using "Auto_submitted" (underscore instead of
2903 hyphen). Since every message generated by Exim is necessarily in response
2904 to another message, thes have all been changed to:
2905
2906 Auto-Submitted: auto-replied
2907
2908 in accordance with these statements in the RFC:
2909
2910 The auto-replied keyword:
2911
2912 - SHOULD be used on messages sent in direct response to another
2913 message by an automatic process,
2914
2915 - MUST NOT be used on manually-generated messages,

2917 - MAY be used on Delivery Status Notifications (DSNs) and Message
2918 Disposition Notifications (MDNs),

2958PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2959 canonical form (as documented). However, after a host name lookup from
2960 the IP address, check_host() was doing a simple string comparison with
2961 addresses acquired from the DNS when checking that the found name did
2962 have the original IP as one of its addresses. Since any found IPv6
2963 addresses are likely to be in abbreviated form, the comparison could
2964 fail. Luckily, there already exists a function for doing the comparison
2965 by converting both addresses to binary, so now that is used instead of
2966 the text comparison.

PH
2968PH/20 There was another similar case to PH/19, when a complete host name was

3144PH/36 When a locally submitted message by a trusted user did not contain a
3145 From: header, and the sender address was obtained from -f or from an SMTP
3146 MAIL command, and the trusted user did not use -F to supply a sender
3147 name, $originator_name was incorrectly used when constructing a From:
3148 header. Furthermore, $originator_name was used for submission mode
3149 messages from external hosts without From: headers in a similar way,
3150 which is clearly wrong.

3263PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3264 with the definition in sysexits.h (which is #included earlier).
3265 Fortunately, Exim does not actually use EX_OK. The code used to try to
3266 preserve the sysexits.h value, by assumimg that macro definitions were
3267 scanned for macro replacements. I have been disabused of this notion,
3268 so now the code just undefines EX_OK before #including unistd.h.

3270PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3271 in the smtp transport. When a block could not be written in a single
3272 write() function, the timeout was being re-applied to each part-write.
3273 This seems wrong - if the receiver was accepting one byte at a time it
3274 would take for ever. The timeout is now adjusted when this happens. It
3275 doesn't have to be particularly precise.
