TK
345TK/01 Add preliminary DKIM support. Currently requires a forked version of
346 ALT-N's libdkim that I have put here:
347 http://duncanthrax.net/exim-experimental/
348
349 Note to Michael Haardt: I had to rename some vars in sieve.c. They
350 were called 'true' and it seems that C99 defines that as a reserved
351 keyword to be used with 'bool' variable types. That means you could
352 not include C99-style headers which use bools without triggering
353 build errors in sieve.c.

368Exim version 4.68
369-----------------
370
371PH/01 Another patch from the Sieve maintainer.
372
6a3bceb1
PH
373PH/02 When an IPv6 address is converted to a string for single-key lookup
374 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
375 dots are used instead of colons so that keys in lsearch files need not
376 contain colons. This was done some time before quoting was made available
377 in lsearch files. However, iplsearch files do require colons in IPv6 keys
378 (notated using the quote facility) so as to distinguish them from IPv4
379 keys. This meant that lookups for IP addresses in host lists did not work
380 for iplsearch lookups.
381
382 This has been fixed by arranging for IPv6 addresses to be expressed with
383 colons if the lookup type is iplsearch. This is not incompatible, because
384 previously such lookups could never work.
385
386 The situation is now rather anomolous, since one *can* have colons in
387 ordinary lsearch keys. However, making the change in all cases is
388 incompatible and would probably break a number of configurations.

393MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
394 conversion specification without a maximum field width, thereby enabling
395 a rogue spamd server to cause a buffer overflow. While nobody in their
396 right mind would setup Exim to query an untrusted spamd server, an
397 attacker that gains access to a server running spamd could potentially
398 exploit this vulnerability to run arbitrary code as the Exim user.

591PH/29 SMTP synchronization checks are implemented when a command is read -
592 there is a check that no more input is waiting when there shouldn't be

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

671 the response to the final '.' that terminates a message, but only in the
672 case where the client has not sent further data following the '.'
673 (unfortunately, this is allowed). However, in many cases there won't be
674 any further data because there won't be any more messages to send. A call
675 to select() can be used: if it shows that the input is "ready", there is
676 either input waiting, or the socket has been closed. An attempt to read
677 the next input character can distinguish the two cases. Previously, Exim
58eb016e 678 would have sent an OK response which the client would never have see.

689PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
690 fixed by 4.65/MH/01 (is this a record?) are fixed:
691
692 (i) An empty string was always treated as zero by the numeric comparison
693 operators. This behaviour has been restored.
694
695 (ii) It is documented that the numeric comparison operators always treat
696 their arguments as decimal numbers. This was broken in that numbers
697 starting with 0 were being interpreted as octal.
698
699 While fixing these problems I realized that there was another issue that
700 hadn't been noticed. Values of message_size_limit (both the global option
701 and the transport option) were treated as octal if they started with 0.
702 The documentation was vague. These values are now always treated as
703 decimal, and I will make that clear in the documentation.

720 large number of recipients for a single message is ridiculous

722 rather than extend the field.

2b1c6e3a
PH
747PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
748 callout verification, Exim cached a "reject" for the entire domain. This
749 is correct for most verifications, but it is not correct for a recipient
750 verification with use_sender or use_postmaster set, because in that case
751 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
752 case of MAIL FROM:<> rejection from other early rejections (e.g.
753 rejection of HELO). When verifying a recipient using a non-null MAIL
754 address, the cache is ignored if it shows MAIL FROM:<> rejection.
755 Whatever the result of the callout, the value of the domain cache is
756 left unchanged (for any other kind of callout, getting as far as trying
757 RCPT means that the domain itself is ok).

796 instead - this is what is used when a message is actually being sent. If
797 there is no remote transport (possible with a router that sets up host
798 addresses), $smtp_active_hostname is used.

14aa5a05 800PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 801 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
802 (a) The code assumed that strncpy() returns a negative number on buffer
803 overflow, which isn't the case. Replaced with Exim's string_format()
804 function.
805 (b) There were several signed/unsigned issues. I just did the minimum
806 hacking in of casts. There is scope for a larger refactoring.
807 (c) The code used strcasecmp() which is not a standard C function.
808 Replaced with Exim's strcmpic() function.
809 (d) The code set only $1; it now sets $auth1 as well.
810 (e) A simple test gave the error "authentication client didn't specify
811 service in request". It would seem that Dovecot has changed its
812 interface. Fortunately there's a specification; I followed it and
813 changed what the client sends and it appears to be working now.

PH
818PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
819 address A is aliased to B and C, where B exists and C does not. Without
820 -v the output is "A verified" because verification stops after a
821 successful redirection if more than one address is generated. However,
822 with -v the child addresses are also verified. Exim was outputting "A
823 failed to verify" and then showing the successful verification for C,
824 with its parentage. It now outputs "B failed to verify", showing B's
825 parentage before showing the successful verification of C.

827PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
828 look up a TXT record in a specific list after matching in a combined
829 list.
830
322050c2
PH
831PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
832 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
833 they consult the DNS. I had assumed they would set it the way they
834 wanted; and indeed my experiments on Linux seem to show that in some
835 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
836 To be on the safe side, however, I have now made the interface to
837 host_find_byname() similar to host_find_bydns(), with an argument
838 containing the DNS resolver options. The host_find_byname() function now
839 sets these options at its start, just as host_find_bydns() does. The smtp
840 transport options dns_qualify_single and dns_search_parents are passed to
841 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
842 of host_find_byname() use the default settings of RES_DEFNAMES
843 (qualify_single) but not RES_DNSRCH (search_parents).
844

PH
845PH/17 Applied (a modified version of) Nico Erfurth's patch to make
846 spool_read_header() do less string testing, by means of a preliminary
847 switch on the second character of optional "-foo" lines. (This is
848 overdue, caused by the large number of possibilities that now exist.
849 Originally there were few.) While I was there, I also converted the
850 str(n)cmp tests so they don't re-test the leading "-" and the first
851 character, in the hope this might squeeze out yet more improvement.
852

PH
853PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
854 flag allowing group syntax was set by the header_syntax check but not
855 turned off, possible causing trouble later; (2) The flag was not being
856 set at all for the header_verify test, causing "group"-style headers to
857 be rejected. I have now set it in this case, and also caused header_
858 verify to ignore an empty address taken from a group. While doing this, I
859 came across some other cases where the code for allowing group syntax
860 while scanning a header line wasn't quite right (mostly, not resetting
861 the flag correctly in the right place). These bugs could have caused
862 trouble for malformed header lines. I hope it is now all correct.
863
602e59e5
PH
864PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
865 with the "reply" argument non-NULL. The code, however (which originally
866 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
867 but it didn't always do it. This confused somebody who was copying the
868 code for some other use. I have removed all the tests.
869
411ef850
PH
870PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
871 feature that was used to support insecure browsers during the U.S. crypto
872 embargo. It requires special client support, and Exim is probably the
873 only MTA that supported it -- and would never use it because real RSA is
874 always available. This code has been removed, because it had the bad
875 effect of slowing Exim down by computing (never used) parameters for the
876 RSA_EXPORT functionality.
877
7befa435
PH
878PH/21 On the advice of Timo Sirainen, added a check to the dovecot
879 authenticator to fail if there's a tab character in the incoming data
880 (there should never be unless someone is messing about, as it's supposed
881 to be base64-encoded). Also added, on Timo's advice, the "secured" option
882 if the connection is using TLS or if the remote IP is the same as the
883 local IP, and the "valid-client-cert option" if a client certificate has
884 been verified.

PH
915
916PH/30 Exim was sometimes attempting to deliver messages that had suffered
917 address errors (4xx response to RCPT) over the same connection as other
918 messages routed to the same hosts. Such deliveries are always "forced",
919 so retry times are not inspected. This resulted in far too many retries
920 for the affected addresses. The effect occurred only when there were more
921 hosts than the hosts_max_try setting in the smtp transport when it had
922 the 4xx errors. Those hosts that it had tried were not added to the list
923 of hosts for which the message was waiting, so if all were tried, there
924 was no problem. Two fixes have been applied:
925
926 (i) If there are any address or message errors in an SMTP delivery, none
927 of the hosts (tried or untried) are now added to the list of hosts
928 for which the message is waiting, so the message should not be a
929 candidate for sending over the same connection that was used for a
930 successful delivery of some other message. This seems entirely
931 reasonable: after all the message is NOT "waiting for some host".
932 This is so "obvious" that I'm not sure why it wasn't done
933 previously. Hope I haven't missed anything, but it can't do any
934 harm, as the worst effect is to miss an optimization.
935
936 (ii) If, despite (i), such a delivery is accidentally attempted, the
937 routing retry time is respected, so at least it doesn't keep
938 hammering the server.

PH
953PH/35 The error "getsockname() failed: connection reset by peer" was being
954 written to the panic log as well as the main log, but it isn't really
955 panic-worthy as it just means the connection died rather early on. I have
956 removed the panic log writing for the ECONNRESET error when getsockname()
957 fails.
958
48c7f9e2
PH
959PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
960 runs only) independently of the message's sender address. This meant
961 that, if the 4xx error was in fact related to the sender, a different
962 message to the same recipient with a different sender could confuse
963 things. In particualar, this can happen when sending to a greylisting
964 server, but other circumstances could also provoke similar problems.
965 I have changed the default so that the retry time for these errors is now
966 based a combination of the sender and recipient addresses. This change
967 can be overridden by setting address_retry_include_sender=false in the
968 smtp transport.

1236PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1237 "Deny" causes Exim to reject the incoming connection with a 554 error.
1238 Unfortunately, if there is a major crisis, such as a disk failure,
1239 tcp-wrappers gives "deny", whereas what one would like would be some
1240 kind of temporary error. A kludge has been added to help with this.
1241 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1242 554 error is used if errno is still zero or contains ENOENT (which occurs
1243 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1244 451 error is used.

1280PH/01 The code for finding all the local interface addresses on a FreeBSD
1281 system running IPv6 was broken. This may well have applied to all BSD
1282 systems, as well as to others that have similar system calls. The broken
1283 code found IPv4 interfaces correctly, but gave incorrect values for the
1284 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1285 that it would not match correctly against @[] and not recognize the IPv6
1286 addresses as local.

1329 autoreply, Exim could try to deliver to a non-existent relative file

1352 (a) Failures to set uid/gid, the current directory, or a process leader
1353 in a subprocess such as that created by queryprogram now generate
1354 suitable debugging ouput when -d is set.

1365 Instead, it always explicitly searches for A/AAAA records. This avoids
1366 major problems that occur when a DNS server includes only records of one
1367 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1368 fixed another bug: if SRV records were looked up and the corresponding
1369 address records were *not* found in the additional section, the port
1370 values from the SRV records were lost.

PH
1380PH/19 When calculating a retry time, Exim used to measure the "time since
1381 failure" by looking at the "first failed" field in the retry record. Now
1382 it does not use this if it is later than than the arrival time of the
1383 message. Instead it uses the arrival time. This makes for better
1384 behaviour in cases where some deliveries succeed, thus re-setting the
1385 "first failed" field. An example is a quota failure for a huge message
1386 when small messages continue to be delivered. Without this change, the
1387 "time since failure" will always be short, possible causing more frequent
1388 delivery attempts for the huge message than are intended.

PH
1485PH/42 The content-scanning code uses fopen() to create files in which to put
1486 message data. Previously it was not paying any attention to the mode of
1487 the files. Exim runs with umask(0) because the rest of the code creates
1488 files with open(), and sets the required mode explicitly. Thus, these
1489 files were ending up world-writeable. This was not a big issue, because,
1490 being within the spool directory, they were not world-accessible. I have
1491 created a function called modefopen, which takes an additional mode
1492 argument. It sets umask(777), creates the file, chmods it to the required
1493 mode, then resets the umask. All the relevant calls to fopen() in the

1531
1532 (i) Exim was not creating retry information for temporary errors given

1534 was used in LMTP mode. This meant that they could be retried too
1535 frequently, and not timed out correctly.
1536
1537 (ii) Exim was setting the flag that allows error details to be returned
1538 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1539 recipients that were returned after the DATA command.
1540
1541PH/53 This is related to PH/52, but is more general: for any failing address,
1542 when detailed error information was permitted to be returned to the

1604 been fixed. However, if bounce_return_message is true and bounce_return_

1615PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1616 function verify_get_ident() calls ip_connect() to connect a socket, but
1617 if the "connect()" function timed out, ip_connect() used to close the
1618 socket. However, verify_get_ident() also closes the socket later, and in
1619 between Exim writes to the log, which may get opened at this point. When
1620 the socket was closed in ip_connect(), the log could get the same file
1621 descriptor number as the socket. This naturally causes chaos. The fix is
1622 not to close the socket in ip_connect(); the socket should be closed by
1623 the function that creates it. There was only one place in the code where
1624 this was missing, in the iplookup router, which I don't think anybody now
1625 uses, but I've fixed it anyway.

1648
1649 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1650 string.
1651
1652 (3) Reset the variables that are obtained from the first argument of
1653 ${prvscheck and used in the second argument before leaving the code,
1654 because their memory is reclaimed, so using them afterwards may do
1655 silly things.
1656
1657 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1658 one (it's much easier than Tom thought :-).
1659
1660 (5) Because of (4), we can now allow for the use of $prvscheck_result

1681PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1682 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1683 not being looked up in the rDNS to get a host name, Exim was showing the
1684 IP address twice in Received: lines, even though the IP addresses were
1685 identical. For example:
1686
1687 Received: from [1.2.3.4] (helo=[1.2.3.4])
1688
1689 However, if the real host name was known, it was omitting the HELO data
1690 if it matched the actual IP address. This has been tidied up so that it
1691 doesn't show the same IP address twice.

1719
1720 Auto-submitted: auto-generated
1721
1722 in the messages that it generates (bounce messages and others, such as
1723 warnings). In the case of bounce messages for non-SMTP mesages, there was
1724 also a typo: it was using "Auto_submitted" (underscore instead of
1725 hyphen). Since every message generated by Exim is necessarily in response
1726 to another message, thes have all been changed to:
1727
1728 Auto-Submitted: auto-replied
1729
1730 in accordance with these statements in the RFC:
1731
1732 The auto-replied keyword:
1733
1734 - SHOULD be used on messages sent in direct response to another
1735 message by an automatic process,
1736

1740 Disposition Notifications (MDNs),

1780PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1781 canonical form (as documented). However, after a host name lookup from
1782 the IP address, check_host() was doing a simple string comparison with
1783 addresses acquired from the DNS when checking that the found name did
1784 have the original IP as one of its addresses. Since any found IPv6
1785 addresses are likely to be in abbreviated form, the comparison could
1786 fail. Luckily, there already exists a function for doing the comparison
1787 by converting both addresses to binary, so now that is used instead of
1788 the text comparison.

2087 Fortunately, Exim does not actually use EX_OK. The code used to try to
2088 preserve the sysexits.h value, by assumimg that macro definitions were
2089 scanned for macro replacements. I have been disabused of this notion,

2306PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2307 that changes the way the GnuTLS parameters are stored in the cache file.
2308 The new format can be generated externally. For backward compatibility,
2309 if the data in the cache doesn't make sense, Exim assumes it has read an
2310 old-format file, and it generates new data and writes a new file. This
2311 means that you can't go back to an older release without removing the
2312 file.
2313
2314PH/03 A redirect router that has both "unseen" and "one_time" set does not
2315 work if there are any delivery delays because "one_time" forces the
2316 parent to be marked "delivered", so its unseen clone is never tried
2317 again. For this reason, Exim now forbids the simultaneous setting of
2318 these two options.
2319
2320PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2321 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2322 entry if you want to know the details. The fix, however, neglected to
2323 consider the case when local delivery batching is involved. The test for
2324 "previously delivered" was not happening when checking to see if an
2325 address could be batched with a previous (undelivered) one; under
2326 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2327 address.

2332PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2333 header_syntax) but Exim was just ignoring anything given after a slash.
2334 In particular, this caused confusion with an attempt to use "verify =
2335 reverse_host_lookup/defer_ok". An error is now given when options are
2336 supplied for verify items that do not have them. (Maybe reverse_host_
2337 lookup should have a defer_ok option, but that's a different point.)

2339PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2381 header file does not have a version number, so I've had to invent a new
2382 value for RADIUS_LIB_TYPE, namely "RADIUSCLIENTNEW" to request the new
2383 API. The code is untested by me (my Linux distribution still has 0.3.2 of
2384 radiusclient), but it was contributed by a Radius user.

2389PH/19 When an Exim process that is running as root has to create an Exim log
2390 file, it does so in a subprocess that runs as exim:exim so as to get the
2391 ownership right at creation (otherwise, other Exim processes might see
2392 the file with the wrong ownership). There was no test for failure of this
2393 fork() call, which would lead to the process getting stuck as it waited
2394 for a non-existent subprocess. Forks do occasionally fail when resources
2395 run out. I reviewed all the other calls to fork(); they all seem to check
2396 for failure.

2398PH/20 When checking for unexpected SMTP input at connect time (before writing
2399 the banner), Exim was not dealing correctly with a non-positive return
2400 from the read() function. If the client had disconnected by this time,
2401 the result was a log entry for a synchronization error with an empty
2402 string after "input=" when read() returned zero. If read() returned -1
2403 (an event I could not check), uninitialized data bytes were printed.
2404 There were reports of junk text (parts of files, etc) appearing after
2405 "input=".

PH
2415PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2416 hadn't been configured. The fix is from Juergen Kreileder, who
2417 understands it better than I do:
2418
2419 "Here's what I see happening with three configured cyrus_sasl
2420 authenticators configured (plain, login, cram-md5):
2421
2422 On startup auth_cyrus_sasl_init() gets called for each of these.
2423 This means three calls to sasl_listmech() without a specified mech_list.
2424 => SASL tests which mechs of all available mechs actually work
2425 => three warnings about OTP not working
2426 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2427
2428 With the patch, sasl_listmech() also gets called three times. But now
2429 SASL's mech_list option is set to the server_mech specified in the the
2430 authenticator. Or in other words, the answer from sasl_listmech()
2431 gets limited to just the mech you're testing for (which is different
2432 for each call.)
2433 => the return list contains just 'plain' or 'login', 'cram-md5' or
2434 nothing depending on the value of ob->server_mech.
2435
2436 I've just tested the patch: Authentication still works fine,
2437 unavailable mechs specified in the exim configuration are still
2438 caught, and the auth.log warnings about OTP are gone."

PH
2502PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2503 the grounds that routing the same address twice would always produce the
2504 same answer. This might have been true once, but it is certainly no
2505 longer true now. Routing a child address may depend on the previous
2506 routing that produced that child. Some complicated redirection strategies
2507 went wrong when messages had multiple recipients, and made Exim's
2508 behaviour dependent on the order in which the addresses were given.
2509
2510 I have moved the duplicate checking until after the routing is complete.
2511 Exim scans the addresses that are assigned to local and remote
2512 transports, and removes any duplicates. This means that more work will be
2513 done, as duplicates will always all be routed, but duplicates are
2514 presumably rare, so I don't expect this is of any significance.
2515
2516 For deliveries to pipes, files, and autoreplies, the duplicate checking
2517 still happens during the routing process, since they are not going to be
2518 routed further.

2563 consistency with the overall process timeout, these timeouts are now
2564 treated as errors, giving rise to delivery failures by default. However,
2565 there is now a new Boolean option for the pipe transport called
2566 timeout_defer, which, if set TRUE, converts the failures into defers for
2567 both kinds of timeout. A transport filter timeout is now identified in

2577A note about Exim versions 4.44 and 4.50
2578----------------------------------------
2579
2580Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2581changes of various kinds. As a consequence, a big documentation update was
2582needed. This delayed the release for rather longer than seemed good, especially
2583in the light of a couple of (minor) security issues. Therefore, the changes
2584that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2585release. So 4.44 and 4.50 are in effect two different branches that both start
2586from 4.43.
2587
2588I have left the 4.50 change log unchanged; it contains all the changes since
25894.43. The change log for 4.44 is below; many of its items are identical to
2590those for 4.50. This seems to be the most sensible way to preserve the
2591historical information.

2609 5. There are several places where Exim runs a non-Exim command in a
2610 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2611 was being done only for the command run by the queryprogram router. It is
2612 now done for all such subprocesses. The other cases are: ${run, transport
2613 filters, and the commands run by the lmtp and pipe transports.

2618 descriptors. Exim was using setrlimit() to set 1000 as a large value
2619 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2620 systems. I've change it so that if it can't get 1000, it tries for 256.

2668 ignore_target_hosts.
2669
267023. When checking ignore_target_hosts for an ipliteral router, no host name was
2671 being passed; this would have caused $sender_host_name to have been used if
2672 matching the list had actually called for a host name (not very likely,
2673 since this list is usually IP addresses). A host name is now passed as
2674 "[x.x.x.x]".

2679
268025. Narrowed the window for a race in the daemon that could cause it to ignore

PH
269429. In an address list, if the pattern was not a regular expression, an empty
2695 subject address (from a bounce message) matched only if the pattern was an
2696 empty string. Non-empty patterns were not even tested. This was the wrong
2697 because it is perfectly reasonable to use an empty address as part of a
2698 database query. An empty address is now tested by patterns that are
2699 lookups. However, all the other forms of pattern expect the subject to
2700 contain a local part and a domain, and therefore, for them, an empty
2701 address still always fails if the pattern is not itself empty.

PH
270330. Exim went into a mad DNS loop when attempting to do a callout where the

PH
270731. Re-factored the code for checking spool and log partition space into a
2708 function that finds that data and another that does the check. The former

2710 $spool_inodes, and $log_inodes.
2711

PH
271232. The RFC2047 encoding function was originally intended for short strings
2713 such as real names; it was not keeping to the 75-character limit for
2714 encoded words that the RFC imposes. It now respects the limit, and
2715 generates multiple encoded words if necessary. To be on the safe side, I
2716 have increased the buffer size for the ${rfc2047: expansion operator from
2717 1024 to 2048 bytes.
2718
063b1e99
PH
271933. It is now permitted to omit both strings after an "if" condition; if the
2720 condition is true, the result is "true". As before, when the second string
2721 is omitted, a false condition yields an empty string. This makes it less
2722 cumbersome to write custom ACL and router conditions.
2723
652e1b65
PH
272434. Failure to deliver a bounce message always caused it to be frozen, even if
2725 there was an errors_to setting on the router. The errors_to setting is now
2726 respected.

PH
273236. The table in the code that translates DNS record types into text (T_A to
2733 "A" for instance) was missing entries for NS and CNAME. It is just possible
2734 that this could have caused confusion if both these types were looked up
2735 for the same domain, because the text type is used as part of Exim's
2736 per-process caching. But the chance of anyone hitting this buglet seems
2737 very small.

PH
273937. The dnsdb lookup has been extended in a number of ways.

2776 introduction of TLS in release 3.20, but "sometimes" must have been rare
2777 because the tests only now provoked it.

278247. exim_tidydb, when checking for the continued existence of a message for

2792 was generating a temporary error. It now behaves as specified.

PH
280152. Exim crashed if a remote delivery caused a very long error message to be
2802 recorded - for instance if somebody sent an entire SpamAssassin report back
2803 as a large number of 550 error lines. This bug was coincidentally fixed by
2804 increasing the size of one of Exim's internal buffers (big_buffer) that
2805 happened as part of the Exiscan merge. However, to be on the safe side, I
2806 have made the code more robust (and fixed the comments that describe what
2807 is going on).

PH
280953. Now that there can be additional text after "Completed" in log lines (if
2810 the queue_time_overall log selector is set), a one-byte patch to exigrep

2812 the line.

PH
281454. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2815 patch that reportedly fixes this has been added. I am not expert enough to
2816 create a test for it. This is what the patch creator wrote:
2817
2818 "I found a little strange behaviour of ldap code when working with
2819 Windows 2003 AD Domain, where users was placed in more than one
2820 Organization Units. When I tried to give exim partial DN, the exit code
2821 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2822 But simultaneously result of request was absolutely normal ldap result,
2823 so I produce this patch..."
2824
3295e65b
PH
2825 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2826 REFERENCE, so I have modified the code to exclude the patch when that macro
2827 is not defined.

PH
282955. Some experimental protocols are using DNS PTR records for new purposes. The
2830 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2831 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2832 leaves it alone. Component reversal etc. now happens only for IP addresses.

2844
2845 (1) $smtp_active_hostname is now available as a variable.
2846 (2) The default for smtp_banner uses $smtp_active_hostname instead
2847 of $primary_hostname.
2848
b975ba52
PH
284960. The host_aton() function is supposed to be passed a string that is known
2850 to be a valid IP address. However, in the case of IPv6 addresses, it was
2851 not checking this. This is a hostage to fortune. Exim now panics and dies
2852 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2853 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2854 components; fortuitously, this particular loophole had already been fixed
2855 by change 4.50/55 above.
2856
2857 If there are any other similar loopholes, the new check in host_aton()
2858 itself should stop them being exploited. The report I received stated that
2859 data on the command line could provoke the exploit when Exim was running as
2860 exim, but did not say which command line option was involved. All I could
2861 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2862 running as the user.

PH
287363. The daemon start-up calls getloadavg() while still root for those OS that
2874 need the first call to be done as root, but it missed one case: when
2875 deliver_queue_load_max is set with deliver_drop_privilege. This is
2876 necessary for the benefit of the queue runner, because there is no re-exec
2877 when deliver_drop_privilege is set.

2881
60dc5e56
PH
288265. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2883 was in use, was not putting the data itself into the right store pool;
2884 consequently, it could be overwritten for a subsequent message in the same
2885 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2886 the caching.)

289067. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2891 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2892 the function were treating the return as a boolean value, which happened to
2893 work because 0=false and not-0=true, but is not correct code.
2894

PH
290270. If an address verification called from an ACL failed, and did not produce a
2903 user-specific message (i.e. there was only a "system" message), nothing was
2904 put in $acl_verify_message. In this situation, it now puts the system
2905 message there.

00f00ca5
PH
290771. Change 4.23/11 added synchronization checking at the start of an SMTP
2908 session; change 4.31/43 added the unwanted input to the log line - except
2909 that it did not do this in the start of session case. It now does.
2910
c9bdd01c
PH
291172. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2912 This is wrong and can cause the other end to generate a synchronization
2913 error if it is another Exim or anything else that does the synchronization
2914 check. A QUIT command is no longer sent after a timeout.

2922 verify = header_sender/callout=defer_ok
2923
76a2d7ba
PH
292475. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2925 those file descriptors could be used for SMTP connections. If anything
2926 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2927 could be sent to the SMTP client, causing chaos. The daemon now opens
2928 stdin, stdout, and stderr to /dev/null when it puts itself into the
2929 background.
2930
293176. Arrange for output from Perl's "warn" command to be written to Exim's main
2932 log by default. The user can override this with suitable Perl magic.
2933
04f7d5b9
PH
293477. The use of log_message on a "discard" ACL verb, which is supposed to add to
2935 the log message when discard triggers, was not working for the DATA ACL or
2936 for the non-SMTP ACL.

PH
293878. Error message wording change in sieve.c.
2939
bb6e88ff
PH
294079. If smtp_accept_max_per_host was set, the number of connections could be
2941 restricted to fewer than expected, because the daemon was trying to set up
2942 a new connection before checking whether the processes handling previous
2943 connections had finished. The check for completed processes is now done
2944 earlier. On busy systems, this bug wouldn't be noticed because something
2945 else would have woken the daemon, and it would have reaped the completed
2946 process earlier.
2947
1e70f85b
PH
294880. If a message was submitted locally by a user whose login name contained one
2949 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2950 It caused a spool format error. I have fixed the spool reading code. A
2951 related problem was that the "from" clause in the Received: line became
2952 illegal because of the space(s). It is now covered by ${quote_local_part.

2968----------------------------------------------------
2969See the note above about the 4.44 and 4.50 releases.
2970----------------------------------------------------
2971
2972
2973Exim version 4.44
2974-----------------
2975
2976 1. Change 4.43/35 introduced a bug that caused file counts to be
2977 incorrectly computed when quota_filecount was set in an appendfile
2978 transport
2979
2980 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2981 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2982 place.
2983
2984 3. Give more explanation in the error message when the command for a transport
2985 filter fails to execute.
2986
2987 4. There are several places where Exim runs a non-Exim command in a
2988 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2989 was being done only for the command run by the queryprogram router. It is
2990 now done for all such subprocesses. The other cases are: ${run, transport
2991 filters, and the commands run by the lmtp and pipe transports.
2992
2993 5. Some older OS have a limit of 256 on the maximum number of file
2994 descriptors. Exim was using setrlimit() to set 1000 as a large value
2995 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2996 systems. I've change it so that if it can't get 1000, it tries for 256.
2997
2998 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2999 was an oversight, and furthermore, ever since the addition of extra
3000 controls (e.g. 4.43/32), the checks on when to allow different forms of
3001 "control" were broken. There should now be diagnostics for all cases when a
3002 control that does not make sense is encountered.
3003
3004 7. $recipients is now available in the predata ACL (oversight).
3005
3006 8. Tidy the search cache before the fork to do a delivery from a message
3007 received from the command line. Otherwise the child will trigger a lookup
3008 failure and thereby defer the delivery if it tries to use (for example) a
3009 cached ldap connection that the parent has called unbind on.
3010
3011 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3012 of $address_data from the recipient verification was clobbered by the
3013 sender verification.
3014
301510. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3016 was its contents. (It was OK if the option was not defined at all.)
3017
301811. A "Completed" log line is now written for messages that are removed from
3019 the spool by the -Mrm option.
3020
302112. $host_address is now set to the target address during the checking of
3022 ignore_target_hosts.
3023
302413. When checking ignore_target_hosts for an ipliteral router, no host name was
3025 being passed; this would have caused $sender_host_name to have been used if
3026 matching the list had actually called for a host name (not very likely,
3027 since this list is usually IP addresses). A host name is now passed as
3028 "[x.x.x.x]".
3029
303014. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3031 code that specifies a non-restarting handler (typically sigaction() in
3032 modern systems) in an attempt to fix a rare and obscure crash bug.
3033
303415. Narrowed the window for a race in the daemon that could cause it to ignore
3035 SIGCHLD signals. This is not a major problem, because they are used only to
3036 wake it up if nothing else does.
3037
303816. A malformed maildirsize file could cause Exim to calculate negative values
3039 for the mailbox size or file count. Odd effects could occur as a result.
3040 The maildirsize information is now recalculated if the size or filecount
3041 end up negative.
3042
304317. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3044 support for a long time. Removed HAVE_SYS_VFS_H.
3045
ea3a6f44 304618. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3047
304819. Allow an empty sender to be matched against a lookup in an address list.
3049 Previously the only cases considered were a regular expression, or an
3050 empty pattern.
3051
305220. Exim went into a mad DNS lookup loop when doing a callout where the
3053 host was specified on the transport, if the DNS lookup yielded more than
3054 one IP address.
3055
ea3a6f44
NM
305621. The RFC2047 encoding function was originally intended for short strings
3057 such as real names; it was not keeping to the 75-character limit for
3058 encoded words that the RFC imposes. It now respects the limit, and
3059 generates multiple encoded words if necessary. To be on the safe side, I
3060 have increased the buffer size for the ${rfc2047: expansion operator from
3061 1024 to 2048 bytes.
bbe902f0 3062
ea3a6f44
NM
306322. Failure to deliver a bounce message always caused it to be frozen, even if
3064 there was an errors_to setting on the router. The errors_to setting is now
3065 respected.
bbe902f0
PH
3066
306723. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3068 canonical form (fully expanded) before being placed in
3069 $sender_host_address.
3070
307124. Updated eximstats to version 1.33
3072
ea3a6f44
NM
307325. Include certificate and key file names in error message when GnuTLS fails
3074 to set them up, because the GnuTLS error message doesn't include the name
3075 of the failing file when there is a problem reading it.
bbe902f0
PH
3076
307726. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3078 As per change 25.
bbe902f0 3079
ea3a6f44

308027. Reset the locale to "C" after calling embedded Perl, in case it was changed
3081 (this can affect the format of dates).
bbe902f0 3082
ea3a6f44
NM
308328. exim_tidydb, when checking for the continued existence of a message for

3086 deleting retry records that should have stayed in existence.

3087
308829. eximstats updated to version 1.35

3153 < 0 before doing a fflush(). This bug looks as though it goes back to the

3158Exim version 4.43
3159-----------------
3160
3161 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3162 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3163 Now it returns an integer. A number of calls were still expecting a T/F
3164 return. Fortuitously, in all cases, the tests worked in OK situations,
3165 which is the norm. However, things would have gone wrong on any write
3166 failures on the smtp file descriptor. This function is used when sending
3167 messages over SMTP and also when doing verify callouts.
3168
3169 2. When Exim is called to do synchronous delivery of a locally submitted
3170 message (the -odf or -odi options), it no longer closes stderr before doing
3171 the delivery.
3172
3173 3. Implemented the mua_wrapper option.
3174
3175 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3176
3177 5. Implemented the functions header_remove(), header_testname(),
3178 header_add_at_position(), and receive_remove_recipient(), and exported them
3179 to local_scan().
3180
3181 6. If an ACL "warn" statement specified the addition of headers, Exim already
3182 inserted X-ACL-Warn: at the start if there was no header name. However, it
3183 was not making this test for the second and subsequent header lines if
3184 there were newlines in the string. This meant that an invalid header could
3185 be inserted if Exim was badly configured.
3186
3187 7. Allow an ACL "warn" statement to add header lines at the start or after all
3188 the Received: headers, as well as at the end.
3189
3190 8. Added the rcpt_4xx retry error code.
3191
3192 9. Added postmaster_mailfrom=xxx to callout verification option.
3193
319410. Added mailfrom=xxxx to the callout verification option, for verify=
3195 header_sender only.
3196
319711. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3198 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3199
320012. Inserted some casts to stop certain compilers warning when using pointer
3201 differences as field lengths or precisions in printf-type calls (mostly
3202 affecting debugging statements).
3203
320413. Added optional readline() support for -be (dynamically loaded).
3205
320614. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3207 same clock tick as a message's arrival, so that its received time was the
3208 same as the "first fail" time on the retry record, and that message
3209 remained on the queue past the ultimate address timeout, every queue runner
3210 would try a delivery (because it was past the ultimate address timeout) but
3211 after another failure, the ultimate address timeout, which should have then
3212 bounced the address, did not kick in. This was a "< instead of <=" error;
3213 in most cases the first failure would have been in the next clock tick
3214 after the received time, and all would be well.
3215
321615. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3217 being recognized when the domain list was tested by the match_domain
3218 condition in an expansion string.
3219
322016. Added the ${str2b64: operator.
3221
322217. Exim was always calling setrlimit() to set a large limit for the number of
3223 processes, without checking whether the existing limit was already
3224 adequate. (It did check for the limit on file descriptors.) Furthermore,
3225 errors from getrlimit() and setrlimit() were being ignored. Now they are
3226 logged to the main and panic logs, but Exim does carry on, to try to do its
3227 job under whatever limits there are.
3228
322918. Imported PCRE 5.0.
3230
323119. Trivial typo in log message " temporarily refused connection" (the leading
3232 space).
3233
323420. If the log selector return_path_on_delivery was set and an address was
3235 redirected to /dev/null, the delivery process crashed because it assumed
3236 that a return path would always be set for a "successful" delivery. In this
3237 case, the whole delivery is bypassed as an optimization, and therefore no
3238 return path is set.
3239
324021. Internal re-arrangement: the function for sending a challenge and reading
3241 a response while authentication was assuming a zero-terminated challenge
3242 string. It's now changed to take a pointer and a length, to allow for
3243 binary data in such strings.
3244
324522. Added the cyrus_sasl authenticator (code supplied by MBM).
3246
324723. Exim was not respecting finduser_retries when seeking the login of the
3248 uid under which it was called; it was always trying 10 times. (The default
3249 setting of finduser_retries is zero.) Also, it was sleeping after the final
3250 failure, which is pointless.
3251
325224. Implemented tls_on_connect_ports.
3253
325425. Implemented acl_smtp_predata.
3255
325626. If the domain in control=submission is set empty, Exim assumes that the
3257 authenticated id is a complete email address when it generates From: or
3258 Sender: header lines.
3259
326027. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3261 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3262 chown and chgrp in /bin and hostname in /usr/bin.
3263
326428. Exim was keeping the "process log" file open after each use, just as it
3265 does for the main log. This opens the possibility of it remaining open for
3266 long periods when the USR1 signal hits a daemon. Occasional processlog
3267 errors were reported, that could have been caused by this. Anyway, it seems
3268 much more sensible not to leave this file open at all, so that is what now
3269 happens.
3270
327129. The long-running daemon process does not normally write to the log once it
3272 has entered its main loop, and it closes the log before doing so. This is
3273 so that log files can straightforwardly be renamed and moved. However,
3274 there are a couple of unusual error situations where the daemon does write
3275 log entries, and I had neglected to close the log afterwards.
3276
327730. The text of an SMTP error response that was received during a remote
3278 delivery was being truncated at 512 bytes. This is too short for some of
3279 the long messages that one sometimes sees. I've increased the limit to
3280 1024.
3281
328231. It is now possible to make retry rules that apply only when a message has a
3283 specific sender, in particular, an empty sender.
3284
328532. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3286 it possible to be selective about when SMTP synchronization is enforced.
3287
328833. Added "control = caseful_local_part" and "control = "caselower_local_part".
3289
329032. Implemented hosts_connection_nolog.
3291
329233. Added an ACL for QUIT.
3293
329434. Setting "delay_warning=" to disable warnings was not working; it gave a
3295 syntax error.
3296
329735. Added mailbox_size and mailbox_filecount to appendfile.
3298
329936. Added control = no_multiline_responses to ACLs.
3300
330137. There was a bug in the logic of the code that waits for the clock to tick
3302 in the case where the clock went backwards by a substantial amount such
3303 that the microsecond fraction of "now" was more than the microsecond
3304 fraction of "then" (but the whole seconds number was less).
3305
330638. Added support for the libradius Radius client library this is found on
3307 FreeBSD (previously only the radiusclient library was supported).
3308
3309
3310Exim version 4.42
3311-----------------
3312
3313 1. When certain lookups returned multiple values in the form name=value, the
3314 quoting of the values was not always being done properly. Specifically:
3315 (a) If the value started with a double quote, but contained no whitespace,
3316 it was not quoted.
3317 (b) If the value contained whitespace other than a space character (i.e.
3318 tabs or newlines or carriage returns) it was not quoted.
3319 This fix has been applied to the mysql and pgsql lookups by writing a
3320 separate quoting function and calling it from the lookup code. The fix
3321 should probably also be applied to nisplus, ibase and oracle lookups, but
3322 since I cannot test any of those, I have not disturbed their existing code.
3323
3324 2. A hit in the callout cache for a specific address caused a log line with no
3325 reason for rejecting RCPT. Now it says "Previous (cached) callout
3326 verification failure".
3327
3328 3. There was an off-by-one bug in the queryprogram router. An over-long
3329 return line was truncated at 256 instead of 255 characters, thereby
3330 overflowing its buffer with the terminating zero. As well as fixing this, I
3331 have increased the buffer size to 1024 (and made a note to document this).
3332
3333 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3334 when Exim is waiting for an SMTP response from a remote server, Exim
3335 restarts its select() call on the socket, thereby resetting its timeout.
3336 This is not a problem when such interrupts are rare. Somebody set up a cron
3337 job to run exiwhat every 2 minutes, which is less than the normal select()
3338 timeout (5 or 10 minutes). This meant that the select() timeout never
3339 kicked in because it was always reset. I have fixed this by comparing the
3340 time when an interrupt arrives with the time at the start of the first call
3341 to select(). If more time than the timeout has elapsed, the interrupt is
3342 treated as a timeout.
3343
3344 5. Some internal re-factoring in preparation for the addition of Sieve
3345 extensions (by MH). In particular, the "personal" test is moved to a
3346 separate function, and given an option for scanning Cc: and Bcc: (which is
3347 not set for Exim filters).
3348
3349 6. When Exim created an email address using the login of the caller as the
3350 local part (e.g. when creating a From: or Sender: header line), it was not
3351 quoting the local part when it contained special characters such as @.
3352
3353 7. Installed new OpenBSD configuration files.
3354
3355 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3356 try to make them clearer.
3357
3358 9. Callout options, other than the timeout value, were being ignored when
3359 verifying sender addresses in header lines. For example, when using
3360
3361 verify = header_sender/callout=no_cache
3362
3363 the cache was (incorrectly) being used.
3364
336510. Added a missing instance of ${EXE} to the exim_install script; this affects
3366 only the Cygwin environment.
3367
336811. When return_path_on_delivery was set as a log selector, if different remote
3369 addresses in the same message used different return paths and parallel
3370 remote delivery occurred, the wrong values would sometimes be logged.
3371 (Whenever a remote delivery process finished, the return path value from
3372 the most recently started remote delivery process was logged.)
3373
337412. RFC 3848 specifies standard names for the "with" phrase in Received: header
3375 lines when AUTH and/or TLS are in use. This is the "received protocol"
3376 field. Exim used to use "asmtp" for authenticated SMTP, without any
3377 indication (in the protocol name) for TLS use. Now it follows the RFC and
3378 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3379 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3380 names appear in log lines as well as in Received: header lines.
3381
338213. Installed MH's patches for Sieve to add the "copy" and "vacation"
3383 extensions, and comparison tests, and to fix some bugs.
3384
338514. Changes to the "personal" filter test:
3386
3387 (1) The test was buggy in that it was just doing the equivalent of
3388 "contains" tests on header lines. For example, if a user's address was
3389 anne@some.where, the "personal" test would incorrectly be true for
3390
3391 To: susanne@some.where
3392
3393 This test is now done by extracting each address from the header in turn,
3394 and checking the entire address. Other tests that are part of "personal"
3395 are now done using regular expressions (for example, to check local parts
3396 of addresses in From: header lines).
3397
3398 (2) The list of non-personal local parts in From: addresses has been
3399 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3400 taken from the Sieve specification recommendations.
3401
3402 (3) If the message contains any header line starting with "List-" it is
3403 treated as non-personal.
3404
3405 (4) The test for "circular" in the Subject: header line has been removed
3406 because it now seems ill-conceived.
3407
340815. Minor typos in src/EDITME comments corrected.
3409
341016. Installed latest exipick from John Jetmore.
3411
341217. If headers_add on a router specified a text string that was too long for
3413 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3414 of string_sprintf() is now avoided.
3415
341618. $message_body_size was not set (it was always zero) when running the DATA
3417 ACL and the local_scan() function.
3418
341919. For the "mail" command in an Exim filter, no default was being set for
3420 the once_repeat time, causing a random time value to be used if "once" was
3421 specified. (If the value happened to be <= 0, no repeat happened.) The
3422 default is now 0s, meaning "never repeat". The "vacation" command was OK
3423 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3424 (I found it when inspecting the code).
3425
342620. There is now an overall timeout for performing a callout verification. It
3427 defaults to 4 times the callout timeout, which applies to individual SMTP
3428 commands during the callout. The overall timeout applies when there is more
3429 than one host that can be tried. The timeout is checked before trying the
3430 next host. This prevents very long delays if there are a large number of
3431 hosts and all are timing out (e.g. when the network connections are timing
3432 out). The value of the overall timeout can be changed by specifying an
3433 additional sub-option for "callout", called "maxwait". For example:
3434
3435 verify = sender/callout=5s,maxwait=20s
3436
343721. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3438 to the end before writing, but this should make it even safer).
3439
344022. Exim was forgetting that it had advertised PIPELINING for the second and
3441 subsequent messages on an SMTP connection. It was also not resetting its
3442 memory on STARTTLS and an internal HELO.
3443
344423. When Exim logs an SMTP synchronization error within a session, it now
3445
