7JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
8 and 3.4.4 - once the server is enabled to respond to an OCSP request
9 it does even when not requested, resulting in a stapling non-aware
10 client dropping the TLS connection.

12TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
13 support variable-length bit vectors. No functional change.

TF
15TF/02 Improve the consistency of logging incoming and outgoing interfaces.
16 The I= interface field on outgoing lines is now after the H= remote
17 host field, same as incoming lines. There is a separate
18 outgoing_interface log selector which allows you to disable the
19 outgoing I= field.

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

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

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.

55 it.
56
01a4a5c5 57JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 58 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
59 can be used to disable this per-host. The build option
60 EXPERIMENTAL_CERTNAMES is withdrawn.

76 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
77 under the control of the dsn_advertise_hosts option, and routers may
78 have a dsn_lasthop option.

167Exim version 4.85
168-----------------
169TL/01 When running the test suite, the README says that variables such as
170 no_msglog_check are global and can be placed anywhere in a specific
171 test's script, however it was observed that placement needed to be near
172 the beginning for it to behave that way. Changed the runtest perl
173 script to read through the entire script once to detect and set these
174 variables, reset to the beginning of the script, and then run through
175 the script parsing/test process like normal.

202JH/05 Fix results-pipe from transport process. Several recipients, combined
203 with certificate use, exposed issues where response data items split
204 over buffer boundaries were not parsed properly. This eventually
205 resulted in duplicates being sent. This issue only became common enough
206 to notice due to the introduction of conection certificate information,
207 the item size being so much larger. Found and fixed by Wolfgang Breyha.

aec45841 219 and $event_defer_errno. There is a new variable $verify_mode, usable in

280
281 When a message was received over SMTP with TLS, Exim failed to clear up
282 the incoming connection properly after forking off the child process to
283 deliver the message. In some situations the subsequent outgoing
284 delivery connection happened to have the same fd number as the incoming
285 connection previously had. Exim would try to use TLS and fail, logging

532TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
533
534 When a queue runner is handling a message, Exim first routes the
535 recipient addresses, during which it prunes them based on the retry
536 hints database. After that it attempts to deliver the message to
537 any remaining recipients. It then updates the hints database using
538 the retry rules.
539
540 So if a recipient address works intermittently, it can get repeatedly
541 deferred at routing time. The retry hints record remains fresh so the
542 address never reaches the final cutoff time.
543
544 This is a fairly common occurrence when a user is bumping up against
545 their storage quota. Exim had some logic in its local delivery code
546 to deal with this. However it did not apply to per-recipient defers
547 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
548
1ddeb334
TF
549 This change adds a proper retry rule check during routing so that the
550 final cutoff time is checked against the message's age. We only do
551 this check if there is an address retry record and there is not a
552 domain retry record; this implies that previous attempts to handle
553 the address had the retry_use_local_parts option turned on. We use
554 this as an approximation for the destination being like a local
555 delivery, as in LMTP.
67bd1ab3
TF
556
557 I suspect this new check makes the old local delivery cutoff check
558 redundant, but I have not verified this so I left the code in place.

593 Server implementation by Todd Lyons, client by JH.
594 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
595 config variable "prdr_enable" controls whether the server
596 advertises the facility. If the client requests PRDR a new
597 acl_data_smtp_prdr ACL is called once for each recipient, after
598 the body content is received and before the acl_smtp_data ACL.
599 The client is controlled by bolth of: a hosts_try_prdr option
600 on the smtp transport, and the server advertisement.
601 Default client logging of deliveries and rejections involving
602 PRDR are flagged with the string "PRDR".

880TF/03 Make the exiwhat support code safe for signals. Previously Exim might
881 lock up or crash if it happened to be inside a call to libc when it
882 got a SIGUSR1 from exiwhat.
883
884 The SIGUSR1 handler appends the current process status to the process
885 log which is later printed by exiwhat. It used to use the general
886 purpose logging code to do this, but several functions it calls are
887 not safe for signals.
888
889 The new output code in the SIGUSR1 handler is specific to the process
890 log, and simple enough that it's easy to inspect for signal safety.
891 Removing some special cases also simplifies the general logging code.
892 Removing the spurious timestamps from the process log simplifies
893 exiwhat.

TF
895TF/04 Improved ratelimit ACL condition.
896
897 The /noupdate option has been deprecated in favour of /readonly which
898 has clearer semantics. The /leaky, /strict, and /readonly update modes
899 are mutually exclusive. The update mode is no longer included in the
900 database key; it just determines when the database is updated. (This
901 means that when you upgrde Exim will forget old rate measurements.)
902
903 Exim now checks that the per_* options are used with an update mode that
904 makes sense for the current ACL. For example, when Exim is processing a
905 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
906 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
907 must specify per_mail/readonly. If you omit the update mode it defaults to
908 /leaky where that makes sense (as before) or /readonly where required.
909
910 The /noupdate option is now undocumented but still supported for
911 backwards compatibility. It is equivalent to /readonly except that in
912 ACLs where /readonly is required you may specify /leaky/noupdate or
913 /strict/noupdate which are treated the same as /readonly.
914
915 A useful new feature is the /count= option. This is a generalization
916 of the per_byte option, so that you can measure the throughput of other
917 aggregate values. For example, the per_byte option is now equivalent
918 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
919
920 The per_rcpt option has been generalized using the /count= mechanism
921 (though it's more complicated than the per_byte equivalence). When it is
922 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
923 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
924 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
925 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
926 Note that using per_rcpt with a non-readonly update mode in more than
927 one ACL will cause the recipients to be double-counted. (The per_mail
928 and per_byte options don't have this problem.)
929
930 The handling of very low rates has changed slightly. If the computed rate
931 is less than the event's count (usually one) then this event is the first
932 after a long gap. In this case the rate is set to the same as this event's
933 count, so that the first message of a spam run is counted properly.
934
935 The major new feature is a mechanism for counting the rate of unique
936 events. The new per_addr option counts the number of different
937 recipients that someone has sent messages to in the last time period. It
938 behaves like per_rcpt if all the recipient addresses are different, but
939 duplicate recipient addresses do not increase the measured rate. Like
940 the /count= option this is a general mechanism, so the per_addr option
941 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
942 example, measure the rate that a client uses different sender addresses
943 with the options per_mail/unique=$sender_address. There are further
944 details in the main documentation.

1516PH/01 Another patch from the Sieve maintainer.
1517
6a3bceb1
PH
1518PH/02 When an IPv6 address is converted to a string for single-key lookup
1519 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1520 dots are used instead of colons so that keys in lsearch files need not
1521 contain colons. This was done some time before quoting was made available
1522 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1523 (notated using the quote facility) so as to distinguish them from IPv4
1524 keys. This meant that lookups for IP addresses in host lists did not work
1525 for iplsearch lookups.
1526
1527 This has been fixed by arranging for IPv6 addresses to be expressed with
1528 colons if the lookup type is iplsearch. This is not incompatible, because
1529 previously such lookups could never work.
1530
1531 The situation is now rather anomolous, since one *can* have colons in
1532 ordinary lsearch keys. However, making the change in all cases is
1533 incompatible and would probably break a number of configurations.

1538MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1539 conversion specification without a maximum field width, thereby enabling
1540 a rogue spamd server to cause a buffer overflow. While nobody in their
1541 right mind would setup Exim to query an untrusted spamd server, an
1542 attacker that gains access to a server running spamd could potentially
1543 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1548MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1549 a directory entry by the name of the lookup key. Previously, if a
1550 symlink pointed to a non-existing file or a file in a directory that
1551 Exim lacked permissions to read, a lookup for a key matching that
1552 symlink would fail. Now it is enough that a matching directory entry
1553 exists, symlink or not. (Bugzilla 503.)

1736PH/29 SMTP synchronization checks are implemented when a command is read -
1737 there is a check that no more input is waiting when there shouldn't be

1739 some time before the response is written. In this time, more input might
1740 arrive, invalidly. So now there are extra checks after an ACL has run for
1741 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1742 pipelining has not been advertised.

1798 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1816 the response to the final '.' that terminates a message, but only in the
1817 case where the client has not sent further data following the '.'
1818 (unfortunately, this is allowed). However, in many cases there won't be
1819 any further data because there won't be any more messages to send. A call
1820 to select() can be used: if it shows that the input is "ready", there is
1821 either input waiting, or the socket has been closed. An attempt to read
1822 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1823 would have sent an OK response which the client would never have see.

1834PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1835 fixed by 4.65/MH/01 (is this a record?) are fixed:
1836
1837 (i) An empty string was always treated as zero by the numeric comparison
1838 operators. This behaviour has been restored.
1839
1840 (ii) It is documented that the numeric comparison operators always treat
1841 their arguments as decimal numbers. This was broken in that numbers
1842 starting with 0 were being interpreted as octal.
1843
1844 While fixing these problems I realized that there was another issue that
1845 hadn't been noticed. Values of message_size_limit (both the global option
1846 and the transport option) were treated as octal if they started with 0.
1847 The documentation was vague. These values are now always treated as
1848 decimal, and I will make that clear in the documentation.

1865 large number of recipients for a single message is ridiculous

2b1c6e3a
PH
1892PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1893 callout verification, Exim cached a "reject" for the entire domain. This
1894 is correct for most verifications, but it is not correct for a recipient
1895 verification with use_sender or use_postmaster set, because in that case
1896 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1897 case of MAIL FROM:<> rejection from other early rejections (e.g.
1898 rejection of HELO). When verifying a recipient using a non-null MAIL
1899 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1900 Whatever the result of the callout, the value of the domain cache is
1901 left unchanged (for any other kind of callout, getting as far as trying
1902 RCPT means that the domain itself is ok).

1938 probably the interface on which it is arriving) and not to the outgoing
1939 callout (which could be using a different interface). This has been
1940 changed to use the value of the helo_data option from the smtp transport
1941 instead - this is what is used when a message is actually being sent. If
1942 there is no remote transport (possible with a router that sets up host
1943 addresses), $smtp_active_hostname is used.

7befa435 1946 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1947 (a) The code assumed that strncpy() returns a negative number on buffer
1948 overflow, which isn't the case. Replaced with Exim's string_format()
1949 function.
1950 (b) There were several signed/unsigned issues. I just did the minimum
1951 hacking in of casts. There is scope for a larger refactoring.
1952 (c) The code used strcasecmp() which is not a standard C function.
1953 Replaced with Exim's strcmpic() function.
1954 (d) The code set only $1; it now sets $auth1 as well.
1955 (e) A simple test gave the error "authentication client didn't specify

1963PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1964 address A is aliased to B and C, where B exists and C does not. Without
1965 -v the output is "A verified" because verification stops after a
1966 successful redirection if more than one address is generated. However,
1967 with -v the child addresses are also verified. Exim was outputting "A
1968 failed to verify" and then showing the successful verification for C,
1969 with its parentage. It now outputs "B failed to verify", showing B's
1970 parentage before showing the successful verification of C.

PH
1976PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1977 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1978 they consult the DNS. I had assumed they would set it the way they
1979 wanted; and indeed my experiments on Linux seem to show that in some
1980 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1981 To be on the safe side, however, I have now made the interface to
1982 host_find_byname() similar to host_find_bydns(), with an argument
1983 containing the DNS resolver options. The host_find_byname() function now
1984 sets these options at its start, just as host_find_bydns() does. The smtp
1985 transport options dns_qualify_single and dns_search_parents are passed to
1986 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1987 of host_find_byname() use the default settings of RES_DEFNAMES
1988 (qualify_single) but not RES_DNSRCH (search_parents).

1990PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1991 spool_read_header() do less string testing, by means of a preliminary
1992 switch on the second character of optional "-foo" lines. (This is
1993 overdue, caused by the large number of possibilities that now exist.
1994 Originally there were few.) While I was there, I also converted the
1995 str(n)cmp tests so they don't re-test the leading "-" and the first
1996 character, in the hope this might squeeze out yet more improvement.

1998PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1999 flag allowing group syntax was set by the header_syntax check but not
2000 turned off, possible causing trouble later; (2) The flag was not being
2001 set at all for the header_verify test, causing "group"-style headers to
2002 be rejected. I have now set it in this case, and also caused header_
2003 verify to ignore an empty address taken from a group. While doing this, I
2004 came across some other cases where the code for allowing group syntax
2005 while scanning a header line wasn't quite right (mostly, not resetting
2006 the flag correctly in the right place). These bugs could have caused
2007 trouble for malformed header lines. I hope it is now all correct.

2015PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

2017 embargo. It requires special client support, and Exim is probably the
2018 only MTA that supported it -- and would never use it because real RSA is
2019 always available. This code has been removed, because it had the bad
2020 effect of slowing Exim down by computing (never used) parameters for the
2021 RSA_EXPORT functionality.

2060
2061PH/30 Exim was sometimes attempting to deliver messages that had suffered
2062 address errors (4xx response to RCPT) over the same connection as other
2063 messages routed to the same hosts. Such deliveries are always "forced",
2064 so retry times are not inspected. This resulted in far too many retries
2065 for the affected addresses. The effect occurred only when there were more
2066 hosts than the hosts_max_try setting in the smtp transport when it had
2067 the 4xx errors. Those hosts that it had tried were not added to the list
2068 of hosts for which the message was waiting, so if all were tried, there
2069 was no problem. Two fixes have been applied:
2070
2071 (i) If there are any address or message errors in an SMTP delivery, none
2072 of the hosts (tried or untried) are now added to the list of hosts
2073 for which the message is waiting, so the message should not be a
2074 candidate for sending over the same connection that was used for a
2075 successful delivery of some other message. This seems entirely
2076 reasonable: after all the message is NOT "waiting for some host".
2077 This is so "obvious" that I'm not sure why it wasn't done
2078 previously. Hope I haven't missed anything, but it can't do any
2079 harm, as the worst effect is to miss an optimization.
2080
2081 (ii) If, despite (i), such a delivery is accidentally attempted, the
2082 routing retry time is respected, so at least it doesn't keep
2083 hammering the server.

2098PH/35 The error "getsockname() failed: connection reset by peer" was being
2099 written to the panic log as well as the main log, but it isn't really

2101 removed the panic log writing for the ECONNRESET error when getsockname()
2102 fails.
2103
48c7f9e2
PH
2104PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2105 runs only) independently of the message's sender address. This meant
2106 that, if the 4xx error was in fact related to the sender, a different
2107 message to the same recipient with a different sender could confuse
2108 things. In particualar, this can happen when sending to a greylisting
2109 server, but other circumstances could also provoke similar problems.
2110 I have changed the default so that the retry time for these errors is now
2111 based a combination of the sender and recipient addresses. This change
2112 can be overridden by setting address_retry_include_sender=false in the
2113 smtp transport.

2381PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2382 "Deny" causes Exim to reject the incoming connection with a 554 error.
2383 Unfortunately, if there is a major crisis, such as a disk failure,
2384 tcp-wrappers gives "deny", whereas what one would like would be some
2385 kind of temporary error. A kludge has been added to help with this.
2386 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2387 554 error is used if errno is still zero or contains ENOENT (which occurs
2388 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2389 451 error is used.

2425PH/01 The code for finding all the local interface addresses on a FreeBSD
2426 system running IPv6 was broken. This may well have applied to all BSD
2427 systems, as well as to others that have similar system calls. The broken
2428 code found IPv4 interfaces correctly, but gave incorrect values for the
2429 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2430 that it would not match correctly against @[] and not recognize the IPv6
2431 addresses as local.

2474 autoreply, Exim could try to deliver to a non-existent relative file

2497 (a) Failures to set uid/gid, the current directory, or a process leader
2498 in a subprocess such as that created by queryprogram now generate
2499 suitable debugging ouput when -d is set.

2509 additional section of a DNS packet that returns MX or SRV records.
2510 Instead, it always explicitly searches for A/AAAA records. This avoids
2511 major problems that occur when a DNS server includes only records of one
2512 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2513 fixed another bug: if SRV records were looked up and the corresponding
2514 address records were *not* found in the additional section, the port
2515 values from the SRV records were lost.

PH
2525PH/19 When calculating a retry time, Exim used to measure the "time since
2526 failure" by looking at the "first failed" field in the retry record. Now
2527 it does not use this if it is later than than the arrival time of the
2528 message. Instead it uses the arrival time. This makes for better
2529 behaviour in cases where some deliveries succeed, thus re-setting the
2530 "first failed" field. An example is a quota failure for a huge message
2531 when small messages continue to be delivered. Without this change, the
2532 "time since failure" will always be short, possible causing more frequent
2533 delivery attempts for the huge message than are intended.

2630PH/42 The content-scanning code uses fopen() to create files in which to put
2631 message data. Previously it was not paying any attention to the mode of
2632 the files. Exim runs with umask(0) because the rest of the code creates
2633 files with open(), and sets the required mode explicitly. Thus, these
2634 files were ending up world-writeable. This was not a big issue, because,
2635 being within the spool directory, they were not world-accessible. I have
2636 created a function called modefopen, which takes an additional mode
2637 argument. It sets umask(777), creates the file, chmods it to the required
2638 mode, then resets the umask. All the relevant calls to fopen() in the

2676
2677 (i) Exim was not creating retry information for temporary errors given

2679 was used in LMTP mode. This meant that they could be retried too
2680 frequently, and not timed out correctly.
2681
2682 (ii) Exim was setting the flag that allows error details to be returned
2683 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2684 recipients that were returned after the DATA command.
2685
2686PH/53 This is related to PH/52, but is more general: for any failing address,
2687 when detailed error information was permitted to be returned to the

2746PH/68 The bounce_return_message and bounce_return_body options were not being

2748 In particular, this applied to messages rejected by the ACL. This bug has
2749 been fixed. However, if bounce_return_message is true and bounce_return_
2750 body is false, the headers that are returned for a non-SMTP message
2751 include only those that have been read before the error was detected.

2760PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2761 function verify_get_ident() calls ip_connect() to connect a socket, but
2762 if the "connect()" function timed out, ip_connect() used to close the
2763 socket. However, verify_get_ident() also closes the socket later, and in
2764 between Exim writes to the log, which may get opened at this point. When
2765 the socket was closed in ip_connect(), the log could get the same file
2766 descriptor number as the socket. This naturally causes chaos. The fix is
2767 not to close the socket in ip_connect(); the socket should be closed by
2768 the function that creates it. There was only one place in the code where
2769 this was missing, in the iplookup router, which I don't think anybody now
2770 uses, but I've fixed it anyway.

2793
2794 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2795 string.
2796
2797 (3) Reset the variables that are obtained from the first argument of
2798 ${prvscheck and used in the second argument before leaving the code,
2799 because their memory is reclaimed, so using them afterwards may do
2800 silly things.
2801
2802 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2803 one (it's much easier than Tom thought :-).
2804
2805 (5) Because of (4), we can now allow for the use of $prvscheck_result

2821 may be more than one such address. If so, they are comma-separated, like

2826PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2827 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2828 not being looked up in the rDNS to get a host name, Exim was showing the
2829 IP address twice in Received: lines, even though the IP addresses were
2830 identical. For example:
2831
2832 Received: from [1.2.3.4] (helo=[1.2.3.4])
2833
2834 However, if the real host name was known, it was omitting the HELO data
2835 if it matched the actual IP address. This has been tidied up so that it
2836 doesn't show the same IP address twice.

2862PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2864
2865 Auto-submitted: auto-generated
2866
2867 in the messages that it generates (bounce messages and others, such as
2868 warnings). In the case of bounce messages for non-SMTP mesages, there was
2869 also a typo: it was using "Auto_submitted" (underscore instead of
2870 hyphen). Since every message generated by Exim is necessarily in response
2871 to another message, thes have all been changed to:
2872
2873 Auto-Submitted: auto-replied
2874
2875 in accordance with these statements in the RFC:
2876
2877 The auto-replied keyword:
2878
2879 - SHOULD be used on messages sent in direct response to another
2880 message by an automatic process,
2881

2885 Disposition Notifications (MDNs),

2925PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2926 canonical form (as documented). However, after a host name lookup from
2927 the IP address, check_host() was doing a simple string comparison with
2928 addresses acquired from the DNS when checking that the found name did
2929 have the original IP as one of its addresses. Since any found IPv6
2930 addresses are likely to be in abbreviated form, the comparison could
2931 fail. Luckily, there already exists a function for doing the comparison
2932 by converting both addresses to binary, so now that is used instead of
2933 the text comparison.

3151 avoiding the need to install special zones in a real server. This is
3152 backwards compatible; if it can't find the fake resolver, it drops back.

3207PH/03 The warning log line about a condition test deferring for a "warn" verb

PH
3230PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3231 with the definition in sysexits.h (which is #included earlier).
3232 Fortunately, Exim does not actually use EX_OK. The code used to try to
3233 preserve the sysexits.h value, by assumimg that macro definitions were
3234 scanned for macro replacements. I have been disabused of this notion,
3235 so now the code just undefines EX_OK before #including unistd.h.

PH
3237PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3238 in the smtp transport. When a block could not be written in a single
3239 write() function, the timeout was being re-applied to each part-write.
3240 This seems wrong - if the receiver was accepting one byte at a time it
3241 would take for ever. The timeout is now adjusted when this happens. It
3242 doesn't have to be particularly precise.

3308PH/15 The code I had for printing potentially long long variables in PH/11

PH
3311 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3312 to be "long long int" or "long int". This is needed for the internal
3313 formatting function string_vformat().

3315PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3316 the configuration file to be ":syslog", then the script "guesses" where
3317 the logs files are, rather than using the compiled in default. In our
3318 case the guess is not the same as the compiled default, so the script
3319 suddenly stopped working when I started to use syslog. The patch checks
3320 to see if log_file_path is "". If so, it attempts to read it from exim
3321 with no configuration file to get the compiled in version, before it
3322 falls back to the previous guessing code."

3331PH/18 If the "use_postmaster" option was set for a recipient callout together

3336PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3337 patch removes a few documentation additions to RFC 3028, because the
3338 latest draft now contains them. It adds the new en;ascii-case comparator
3339 and a new error check for 8bit text in MIME parts. Comparator and
3340 require names are now matched exactly. I enabled the subaddress
3341 extension, but it is not well tested yet (read: it works for me)."
