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.

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.

37 it.
38
01a4a5c5 39JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 40 is now done by default. The transport option tls_verify_cert_hostnames

JH
41 can be used to disable this per-host. The build option
42 EXPERIMENTAL_CERTNAMES is withdrawn.

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

149Exim version 4.85
150-----------------
151TL/01 When running the test suite, the README says that variables such as
152 no_msglog_check are global and can be placed anywhere in a specific
153 test's script, however it was observed that placement needed to be near
154 the beginning for it to behave that way. Changed the runtest perl
155 script to read through the entire script once to detect and set these
156 variables, reset to the beginning of the script, and then run through
157 the script parsing/test process like normal.

184JH/05 Fix results-pipe from transport process. Several recipients, combined
185 with certificate use, exposed issues where response data items split
186 over buffer boundaries were not parsed properly. This eventually
187 resulted in duplicates being sent. This issue only became common enough
188 to notice due to the introduction of conection certificate information,
189 the item size being so much larger. Found and fixed by Wolfgang Breyha.

261TF/01 Correctly close the server side of TLS when forking for delivery.
262
263 When a message was received over SMTP with TLS, Exim failed to clear up
264 the incoming connection properly after forking off the child process to
265 deliver the message. In some situations the subsequent outgoing
266 delivery connection happened to have the same fd number as the incoming
267 connection previously had. Exim would try to use TLS and fail, logging
268 a "Bad file descriptor" error.

514TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
515
516 When a queue runner is handling a message, Exim first routes the
517 recipient addresses, during which it prunes them based on the retry
518 hints database. After that it attempts to deliver the message to
519 any remaining recipients. It then updates the hints database using
520 the retry rules.
521
522 So if a recipient address works intermittently, it can get repeatedly
523 deferred at routing time. The retry hints record remains fresh so the
524 address never reaches the final cutoff time.
525
526 This is a fairly common occurrence when a user is bumping up against
527 their storage quota. Exim had some logic in its local delivery code
528 to deal with this. However it did not apply to per-recipient defers
529 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
530
1ddeb334
TF
531 This change adds a proper retry rule check during routing so that the
532 final cutoff time is checked against the message's age. We only do
533 this check if there is an address retry record and there is not a
534 domain retry record; this implies that previous attempts to handle
535 the address had the retry_use_local_parts option turned on. We use
536 this as an approximation for the destination being like a local
537 delivery, as in LMTP.
67bd1ab3
TF
538
539 I suspect this new check makes the old local delivery cutoff check
540 redundant, but I have not verified this so I left the code in place.

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

575 Server implementation by Todd Lyons, client by JH.
576 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
577 config variable "prdr_enable" controls whether the server
578 advertises the facility. If the client requests PRDR a new
579 acl_data_smtp_prdr ACL is called once for each recipient, after
580 the body content is received and before the acl_smtp_data ACL.
581 The client is controlled by bolth of: a hosts_try_prdr option
582 on the smtp transport, and the server advertisement.
583 Default client logging of deliveries and rejections involving
584 PRDR are flagged with the string "PRDR".

862TF/03 Make the exiwhat support code safe for signals. Previously Exim might
863 lock up or crash if it happened to be inside a call to libc when it
864 got a SIGUSR1 from exiwhat.
865
866 The SIGUSR1 handler appends the current process status to the process
867 log which is later printed by exiwhat. It used to use the general
868 purpose logging code to do this, but several functions it calls are
869 not safe for signals.
870
871 The new output code in the SIGUSR1 handler is specific to the process
872 log, and simple enough that it's easy to inspect for signal safety.
873 Removing some special cases also simplifies the general logging code.
874 Removing the spurious timestamps from the process log simplifies
875 exiwhat.

TF
877TF/04 Improved ratelimit ACL condition.
878
879 The /noupdate option has been deprecated in favour of /readonly which
880 has clearer semantics. The /leaky, /strict, and /readonly update modes
881 are mutually exclusive. The update mode is no longer included in the
882 database key; it just determines when the database is updated. (This
883 means that when you upgrde Exim will forget old rate measurements.)
884
885 Exim now checks that the per_* options are used with an update mode that
886 makes sense for the current ACL. For example, when Exim is processing a
887 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
888 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
889 must specify per_mail/readonly. If you omit the update mode it defaults to
890 /leaky where that makes sense (as before) or /readonly where required.
891
892 The /noupdate option is now undocumented but still supported for
893 backwards compatibility. It is equivalent to /readonly except that in
894 ACLs where /readonly is required you may specify /leaky/noupdate or
895 /strict/noupdate which are treated the same as /readonly.
896
897 A useful new feature is the /count= option. This is a generalization
898 of the per_byte option, so that you can measure the throughput of other
899 aggregate values. For example, the per_byte option is now equivalent
900 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
901
902 The per_rcpt option has been generalized using the /count= mechanism
903 (though it's more complicated than the per_byte equivalence). When it is
904 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
905 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
906 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
907 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
908 Note that using per_rcpt with a non-readonly update mode in more than
909 one ACL will cause the recipients to be double-counted. (The per_mail
910 and per_byte options don't have this problem.)
911
912 The handling of very low rates has changed slightly. If the computed rate
913 is less than the event's count (usually one) then this event is the first
914 after a long gap. In this case the rate is set to the same as this event's
915 count, so that the first message of a spam run is counted properly.
916
917 The major new feature is a mechanism for counting the rate of unique
918 events. The new per_addr option counts the number of different
919 recipients that someone has sent messages to in the last time period. It
920 behaves like per_rcpt if all the recipient addresses are different, but
921 duplicate recipient addresses do not increase the measured rate. Like
922 the /count= option this is a general mechanism, so the per_addr option
923 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
924 example, measure the rate that a client uses different sender addresses
925 with the options per_mail/unique=$sender_address. There are further
926 details in the main documentation.

PH
1500PH/02 When an IPv6 address is converted to a string for single-key lookup
1501 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1502 dots are used instead of colons so that keys in lsearch files need not
1503 contain colons. This was done some time before quoting was made available
1504 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1505 (notated using the quote facility) so as to distinguish them from IPv4
1506 keys. This meant that lookups for IP addresses in host lists did not work
1507 for iplsearch lookups.
1508
1509 This has been fixed by arranging for IPv6 addresses to be expressed with
1510 colons if the lookup type is iplsearch. This is not incompatible, because
1511 previously such lookups could never work.
1512
1513 The situation is now rather anomolous, since one *can* have colons in
1514 ordinary lsearch keys. However, making the change in all cases is
1515 incompatible and would probably break a number of configurations.

1520MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1521 conversion specification without a maximum field width, thereby enabling
1522 a rogue spamd server to cause a buffer overflow. While nobody in their
1523 right mind would setup Exim to query an untrusted spamd server, an
1524 attacker that gains access to a server running spamd could potentially
1525 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1530MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1531 a directory entry by the name of the lookup key. Previously, if a
1532 symlink pointed to a non-existing file or a file in a directory that
1533 Exim lacked permissions to read, a lookup for a key matching that
1534 symlink would fail. Now it is enough that a matching directory entry
1535 exists, symlink or not. (Bugzilla 503.)

1718PH/29 SMTP synchronization checks are implemented when a command is read -
1719 there is a check that no more input is waiting when there shouldn't be

1721 some time before the response is written. In this time, more input might
1722 arrive, invalidly. So now there are extra checks after an ACL has run for
1723 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1724 pipelining has not been advertised.

PH
1798 the response to the final '.' that terminates a message, but only in the
1799 case where the client has not sent further data following the '.'
1800 (unfortunately, this is allowed). However, in many cases there won't be
1801 any further data because there won't be any more messages to send. A call
1802 to select() can be used: if it shows that the input is "ready", there is
1803 either input waiting, or the socket has been closed. An attempt to read
1804 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1805 would have sent an OK response which the client would never have see.

1816PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1817 fixed by 4.65/MH/01 (is this a record?) are fixed:
1818
1819 (i) An empty string was always treated as zero by the numeric comparison
1820 operators. This behaviour has been restored.
1821
1822 (ii) It is documented that the numeric comparison operators always treat
1823 their arguments as decimal numbers. This was broken in that numbers
1824 starting with 0 were being interpreted as octal.
1825
1826 While fixing these problems I realized that there was another issue that
1827 hadn't been noticed. Values of message_size_limit (both the global option
1828 and the transport option) were treated as octal if they started with 0.
1829 The documentation was vague. These values are now always treated as
1830 decimal, and I will make that clear in the documentation.

1846 is held in a short int, deliveries were likely to be lost. As such a
1847 large number of recipients for a single message is ridiculous
1848 (performance will be very, very poor), I have chosen to impose a limit
1849 rather than extend the field.

2b1c6e3a
PH
1874PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1875 callout verification, Exim cached a "reject" for the entire domain. This
1876 is correct for most verifications, but it is not correct for a recipient
1877 verification with use_sender or use_postmaster set, because in that case
1878 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1879 case of MAIL FROM:<> rejection from other early rejections (e.g.
1880 rejection of HELO). When verifying a recipient using a non-null MAIL
1881 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1882 Whatever the result of the callout, the value of the domain cache is
1883 left unchanged (for any other kind of callout, getting as far as trying
1884 RCPT means that the domain itself is ok).

1918PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1920 probably the interface on which it is arriving) and not to the outgoing
1921 callout (which could be using a different interface). This has been
1922 changed to use the value of the helo_data option from the smtp transport
1923 instead - this is what is used when a message is actually being sent. If
1924 there is no remote transport (possible with a router that sets up host
1925 addresses), $smtp_active_hostname is used.

7befa435 1928 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1929 (a) The code assumed that strncpy() returns a negative number on buffer
1930 overflow, which isn't the case. Replaced with Exim's string_format()
1931 function.
1932 (b) There were several signed/unsigned issues. I just did the minimum
1933 hacking in of casts. There is scope for a larger refactoring.
1934 (c) The code used strcasecmp() which is not a standard C function.
1935 Replaced with Exim's strcmpic() function.
1936 (d) The code set only $1; it now sets $auth1 as well.
1937 (e) A simple test gave the error "authentication client didn't specify
1938 service in request". It would seem that Dovecot has changed its
1939 interface. Fortunately there's a specification; I followed it and
1940 changed what the client sends and it appears to be working now.

1947 -v the output is "A verified" because verification stops after a
1948 successful redirection if more than one address is generated. However,
1949 with -v the child addresses are also verified. Exim was outputting "A
1950 failed to verify" and then showing the successful verification for C,
1951 with its parentage. It now outputs "B failed to verify", showing B's
1952 parentage before showing the successful verification of C.

1960 they consult the DNS. I had assumed they would set it the way they
1961 wanted; and indeed my experiments on Linux seem to show that in some
1962 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1963 To be on the safe side, however, I have now made the interface to
1964 host_find_byname() similar to host_find_bydns(), with an argument
1965 containing the DNS resolver options. The host_find_byname() function now
1966 sets these options at its start, just as host_find_bydns() does. The smtp
1967 transport options dns_qualify_single and dns_search_parents are passed to
1968 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1969 of host_find_byname() use the default settings of RES_DEFNAMES
1970 (qualify_single) but not RES_DNSRCH (search_parents).

1972PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1973 spool_read_header() do less string testing, by means of a preliminary
1974 switch on the second character of optional "-foo" lines. (This is
1975 overdue, caused by the large number of possibilities that now exist.
1976 Originally there were few.) While I was there, I also converted the
1977 str(n)cmp tests so they don't re-test the leading "-" and the first
1978 character, in the hope this might squeeze out yet more improvement.

1980PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1981 flag allowing group syntax was set by the header_syntax check but not
1982 turned off, possible causing trouble later; (2) The flag was not being
1983 set at all for the header_verify test, causing "group"-style headers to
1984 be rejected. I have now set it in this case, and also caused header_
1985 verify to ignore an empty address taken from a group. While doing this, I
1986 came across some other cases where the code for allowing group syntax
1987 while scanning a header line wasn't quite right (mostly, not resetting
1988 the flag correctly in the right place). These bugs could have caused
1989 trouble for malformed header lines. I hope it is now all correct.

1991PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1993 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1994 but it didn't always do it. This confused somebody who was copying the
1995 code for some other use. I have removed all the tests.

1997PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1998 feature that was used to support insecure browsers during the U.S. crypto
1999 embargo. It requires special client support, and Exim is probably the
2000 only MTA that supported it -- and would never use it because real RSA is
2001 always available. This code has been removed, because it had the bad
2002 effect of slowing Exim down by computing (never used) parameters for the
2003 RSA_EXPORT functionality.

2008 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2009 if the connection is using TLS or if the remote IP is the same as the
2010 local IP, and the "valid-client-cert option" if a client certificate has
2011 been verified.

2042
2043PH/30 Exim was sometimes attempting to deliver messages that had suffered
2044 address errors (4xx response to RCPT) over the same connection as other
2045 messages routed to the same hosts. Such deliveries are always "forced",
2046 so retry times are not inspected. This resulted in far too many retries
2047 for the affected addresses. The effect occurred only when there were more
2048 hosts than the hosts_max_try setting in the smtp transport when it had
2049 the 4xx errors. Those hosts that it had tried were not added to the list
2050 of hosts for which the message was waiting, so if all were tried, there
2051 was no problem. Two fixes have been applied:
2052
2053 (i) If there are any address or message errors in an SMTP delivery, none
2054 of the hosts (tried or untried) are now added to the list of hosts
2055 for which the message is waiting, so the message should not be a
2056 candidate for sending over the same connection that was used for a
2057 successful delivery of some other message. This seems entirely
2058 reasonable: after all the message is NOT "waiting for some host".
2059 This is so "obvious" that I'm not sure why it wasn't done
2060 previously. Hope I haven't missed anything, but it can't do any
2061 harm, as the worst effect is to miss an optimization.
2062
2063 (ii) If, despite (i), such a delivery is accidentally attempted, the
2064 routing retry time is respected, so at least it doesn't keep
2065 hammering the server.

2080PH/35 The error "getsockname() failed: connection reset by peer" was being
2081 written to the panic log as well as the main log, but it isn't really
2082 panic-worthy as it just means the connection died rather early on. I have
2083 removed the panic log writing for the ECONNRESET error when getsockname()
2084 fails.
2085
48c7f9e2
PH
2086PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2087 runs only) independently of the message's sender address. This meant
2088 that, if the 4xx error was in fact related to the sender, a different
2089 message to the same recipient with a different sender could confuse
2090 things. In particualar, this can happen when sending to a greylisting
2091 server, but other circumstances could also provoke similar problems.
2092 I have changed the default so that the retry time for these errors is now
2093 based a combination of the sender and recipient addresses. This change
2094 can be overridden by setting address_retry_include_sender=false in the
2095 smtp transport.

2363PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2364 "Deny" causes Exim to reject the incoming connection with a 554 error.
2365 Unfortunately, if there is a major crisis, such as a disk failure,
2366 tcp-wrappers gives "deny", whereas what one would like would be some
2367 kind of temporary error. A kludge has been added to help with this.
2368 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2369 554 error is used if errno is still zero or contains ENOENT (which occurs
2370 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2371 451 error is used.

2393PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2394 folder from quota calculations, a direct delivery into this folder messed
2395 up the contents of the maildirsize file. This was because the regex was
2396 used only to exclude .Trash (or whatever) when the size of the mailbox
2397 was calculated. There was no check that a delivery was happening into an
2398 excluded directory. This bug has been fixed by ignoring all quota

2407PH/01 The code for finding all the local interface addresses on a FreeBSD
2408 system running IPv6 was broken. This may well have applied to all BSD
2409 systems, as well as to others that have similar system calls. The broken
2410 code found IPv4 interfaces correctly, but gave incorrect values for the
2411 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2412 that it would not match correctly against @[] and not recognize the IPv6
2413 addresses as local.

2456 autoreply, Exim could try to deliver to a non-existent relative file

2479 (a) Failures to set uid/gid, the current directory, or a process leader
2480 in a subprocess such as that created by queryprogram now generate
2481 suitable debugging ouput when -d is set.

2492 Instead, it always explicitly searches for A/AAAA records. This avoids
2493 major problems that occur when a DNS server includes only records of one
2494 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2495 fixed another bug: if SRV records were looked up and the corresponding
2496 address records were *not* found in the additional section, the port
2497 values from the SRV records were lost.

PH
2507PH/19 When calculating a retry time, Exim used to measure the "time since
2508 failure" by looking at the "first failed" field in the retry record. Now
2509 it does not use this if it is later than than the arrival time of the
2510 message. Instead it uses the arrival time. This makes for better
2511 behaviour in cases where some deliveries succeed, thus re-setting the
2512 "first failed" field. An example is a quota failure for a huge message
2513 when small messages continue to be delivered. Without this change, the
2514 "time since failure" will always be short, possible causing more frequent
2515 delivery attempts for the huge message than are intended.

2612PH/42 The content-scanning code uses fopen() to create files in which to put

2615 files with open(), and sets the required mode explicitly. Thus, these
2616 files were ending up world-writeable. This was not a big issue, because,
2617 being within the spool directory, they were not world-accessible. I have
2618 created a function called modefopen, which takes an additional mode
2619 argument. It sets umask(777), creates the file, chmods it to the required
2620 mode, then resets the umask. All the relevant calls to fopen() in the

2658
2659 (i) Exim was not creating retry information for temporary errors given

2661 was used in LMTP mode. This meant that they could be retried too
2662 frequently, and not timed out correctly.
2663
2664 (ii) Exim was setting the flag that allows error details to be returned
2665 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2666 recipients that were returned after the DATA command.
2667
2668PH/53 This is related to PH/52, but is more general: for any failing address,
2669 when detailed error information was permitted to be returned to the

2732 body is false, the headers that are returned for a non-SMTP message
2733 include only those that have been read before the error was detected.

2742PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2743 function verify_get_ident() calls ip_connect() to connect a socket, but
2744 if the "connect()" function timed out, ip_connect() used to close the
2745 socket. However, verify_get_ident() also closes the socket later, and in
2746 between Exim writes to the log, which may get opened at this point. When
2747 the socket was closed in ip_connect(), the log could get the same file
2748 descriptor number as the socket. This naturally causes chaos. The fix is
2749 not to close the socket in ip_connect(); the socket should be closed by
2750 the function that creates it. There was only one place in the code where
2751 this was missing, in the iplookup router, which I don't think anybody now
2752 uses, but I've fixed it anyway.

2774 not a single digit.
2775
2776 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2777 string.
2778
2779 (3) Reset the variables that are obtained from the first argument of
2780 ${prvscheck and used in the second argument before leaving the code,
2781 because their memory is reclaimed, so using them afterwards may do
2782 silly things.
2783
2784 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2785 one (it's much easier than Tom thought :-).
2786
2787 (5) Because of (4), we can now allow for the use of $prvscheck_result

2808PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2809 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2810 not being looked up in the rDNS to get a host name, Exim was showing the
2811 IP address twice in Received: lines, even though the IP addresses were
2812 identical. For example:
2813
2814 Received: from [1.2.3.4] (helo=[1.2.3.4])
2815
2816 However, if the real host name was known, it was omitting the HELO data
2817 if it matched the actual IP address. This has been tidied up so that it
2818 doesn't show the same IP address twice.

2846
2847 Auto-submitted: auto-generated
2848
2849 in the messages that it generates (bounce messages and others, such as
2850 warnings). In the case of bounce messages for non-SMTP mesages, there was
2851 also a typo: it was using "Auto_submitted" (underscore instead of
2852 hyphen). Since every message generated by Exim is necessarily in response
2853 to another message, thes have all been changed to:
2854
2855 Auto-Submitted: auto-replied
2856
2857 in accordance with these statements in the RFC:
2858
2859 The auto-replied keyword:
2860
2861 - SHOULD be used on messages sent in direct response to another
2862 message by an automatic process,
2863

2909 the IP address, check_host() was doing a simple string comparison with
2910 addresses acquired from the DNS when checking that the found name did
2911 have the original IP as one of its addresses. Since any found IPv6
2912 addresses are likely to be in abbreviated form, the comparison could
2913 fail. Luckily, there already exists a function for doing the comparison
2914 by converting both addresses to binary, so now that is used instead of
2915 the text comparison.

3148PH/48 A number of further additions for the benefit of the new test suite,

3161TF/07 Exim produced the error message "an SRV record indicated no SMTP
3162 service" if it encountered an MX record with an empty target hostname.

3165TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
3166 if the DNS of the sending site is misconfigured. This is quite a

3168 helo verification defer as a failure.

3179PH/01 When a transport filter timed out in a pipe delivery, and the pipe
3180 command itself ended in error, the underlying message about the transport
3181 filter timeout was being overwritten with the pipe command error. Now the
3182 underlying error message should be appended to the second error message.

PH
3189PH/03 The warning log line about a condition test deferring for a "warn" verb
3190 was being output only once per connection, rather than after each
3191 occurrence (because it was using the same function as for successful
3192 "warn" verbs). This seems wrong, so I have changed it.

3194TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3195 it should not have, which might have caused a crash in the right
3196 circumstances, but probably never did.
3197
3198PH/04 Installed a modified version of Tony Finch's patch to make submission
3199 mode fix the return path as well as the Sender: header line, and to

PH
3212PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3213 with the definition in sysexits.h (which is #included earlier).
3214 Fortunately, Exim does not actually use EX_OK. The code used to try to
3215 preserve the sysexits.h value, by assumimg that macro definitions were
3216 scanned for macro replacements. I have been disabused of this notion,
3217 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 3218

PH
3219PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3220 in the smtp transport. When a block could not be written in a single
3221 write() function, the timeout was being re-applied to each part-write.
3222 This seems wrong - if the receiver was accepting one byte at a time it
3223 would take for ever. The timeout is now adjusted when this happens. It
3224 doesn't have to be particularly precise.

3249TK/06 MBOX spool code: Add real "From " MBOX separator line
3250 so the .eml file is really in mbox format (even though
3251 most programs do not really care). Patch from Alex Miller.
3252
3253TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
3254 The latter is generated from $received_to and is only set if the

3256 obviously out-of-the-box. Patch from Alex Miller.

3258PH/08 The ${def test on a variable was returning false if the variable's
3259 value was "0", contrary to what the specification has always said!

3261
3262PH/09 The syntax error of a character other than { following "${if
3263 def:variable_name" (after optional whitespace) was not being diagnosed.
3264 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3265 accidental colon was present, for example, could give incorrect results.

3271PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.

PH
3290PH/15 The code I had for printing potentially long long variables in PH/11
3291 above was not the best (it lost precision). The length of off_t variables
3292 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3293 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3294 to be "long long int" or "long int". This is needed for the internal
3295 formatting function string_vformat().

PH
3297PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3298 the configuration file to be ":syslog", then the script "guesses" where
3299 the logs files are, rather than using the compiled in default. In our
3300 case the guess is not the same as the compiled default, so the script
3301 suddenly stopped working when I started to use syslog. The patch checks
3302 to see if log_file_path is "". If so, it attempts to read it from exim
3303 with no configuration file to get the compiled in version, before it
3304 falls back to the previous guessing code."

PH
3313PH/18 If the "use_postmaster" option was set for a recipient callout together
3314 with the "random" option, the postmaster address was used as the MAIL
3315 FROM address for the random test, but not for the subsequent recipient
3316 test. It is now used for both.

PH
3318PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3319 patch removes a few documentation additions to RFC 3028, because the
3320 latest draft now contains them. It adds the new en;ascii-case comparator
3321 and a new error check for 8bit text in MIME parts. Comparator and
3322 require names are now matched exactly. I enabled the subaddress
3323 extension, but it is not well tested yet (read: it works for me)."

PH
3325PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3326 rework some of the code of TK/09 above to avoid the hardwired use of
3327 "%lld" and "long long". Replaced the call to snprintf() with a call to
3328 string_vformat().
