TK
324TK/01 Add preliminary DKIM support. Currently requires a forked version of
325 ALT-N's libdkim that I have put here:
326 http://duncanthrax.net/exim-experimental/
327
328 Note to Michael Haardt: I had to rename some vars in sieve.c. They
329 were called 'true' and it seems that C99 defines that as a reserved
330 keyword to be used with 'bool' variable types. That means you could
331 not include C99-style headers which use bools without triggering
332 build errors in sieve.c.

347Exim version 4.68
348-----------------
349
350PH/01 Another patch from the Sieve maintainer.
351
6a3bceb1
PH
352PH/02 When an IPv6 address is converted to a string for single-key lookup
353 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
354 dots are used instead of colons so that keys in lsearch files need not
355 contain colons. This was done some time before quoting was made available
356 in lsearch files. However, iplsearch files do require colons in IPv6 keys
357 (notated using the quote facility) so as to distinguish them from IPv4
358 keys. This meant that lookups for IP addresses in host lists did not work
359 for iplsearch lookups.
360
361 This has been fixed by arranging for IPv6 addresses to be expressed with
362 colons if the lookup type is iplsearch. This is not incompatible, because
363 previously such lookups could never work.
364
365 The situation is now rather anomolous, since one *can* have colons in
366 ordinary lsearch keys. However, making the change in all cases is
367 incompatible and would probably break a number of configurations.

TK
369TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
370 version.
371

MH
372MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
373 conversion specification without a maximum field width, thereby enabling
374 a rogue spamd server to cause a buffer overflow. While nobody in their
375 right mind would setup Exim to query an untrusted spamd server, an
376 attacker that gains access to a server running spamd could potentially
377 exploit this vulnerability to run arbitrary code as the Exim user.

379TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
380 $primary_hostname instead of what libspf2 thinks the hosts name is.
381
0f2cbd1b
MH
382MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
383 a directory entry by the name of the lookup key. Previously, if a
384 symlink pointed to a non-existing file or a file in a directory that
385 Exim lacked permissions to read, a lookup for a key matching that
386 symlink would fail. Now it is enough that a matching directory entry
387 exists, symlink or not. (Bugzilla 503.)

570PH/29 SMTP synchronization checks are implemented when a command is read -
571 there is a check that no more input is waiting when there shouldn't be

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

PH
650 the response to the final '.' that terminates a message, but only in the
651 case where the client has not sent further data following the '.'
652 (unfortunately, this is allowed). However, in many cases there won't be
653 any further data because there won't be any more messages to send. A call
654 to select() can be used: if it shows that the input is "ready", there is
655 either input waiting, or the socket has been closed. An attempt to read
656 the next input character can distinguish the two cases. Previously, Exim
58eb016e 657 would have sent an OK response which the client would never have see.

667
668PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
669 fixed by 4.65/MH/01 (is this a record?) are fixed:
670
671 (i) An empty string was always treated as zero by the numeric comparison
672 operators. This behaviour has been restored.
673
674 (ii) It is documented that the numeric comparison operators always treat
675 their arguments as decimal numbers. This was broken in that numbers
676 starting with 0 were being interpreted as octal.
677
678 While fixing these problems I realized that there was another issue that
679 hadn't been noticed. Values of message_size_limit (both the global option
680 and the transport option) were treated as octal if they started with 0.
681 The documentation was vague. These values are now always treated as
682 decimal, and I will make that clear in the documentation.

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

2b1c6e3a
PH
726PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
727 callout verification, Exim cached a "reject" for the entire domain. This
728 is correct for most verifications, but it is not correct for a recipient
729 verification with use_sender or use_postmaster set, because in that case
730 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
731 case of MAIL FROM:<> rejection from other early rejections (e.g.
732 rejection of HELO). When verifying a recipient using a non-null MAIL
733 address, the cache is ignored if it shows MAIL FROM:<> rejection.
734 Whatever the result of the callout, the value of the domain cache is
735 left unchanged (for any other kind of callout, getting as far as trying
736 RCPT means that the domain itself is ok).

770PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

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

14aa5a05 779PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 780 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
781 (a) The code assumed that strncpy() returns a negative number on buffer
782 overflow, which isn't the case. Replaced with Exim's string_format()
783 function.
784 (b) There were several signed/unsigned issues. I just did the minimum
785 hacking in of casts. There is scope for a larger refactoring.
786 (c) The code used strcasecmp() which is not a standard C function.
787 Replaced with Exim's strcmpic() function.
788 (d) The code set only $1; it now sets $auth1 as well.
789 (e) A simple test gave the error "authentication client didn't specify
790 service in request". It would seem that Dovecot has changed its
791 interface. Fortunately there's a specification; I followed it and
792 changed what the client sends and it appears to be working now.

797PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
798 address A is aliased to B and C, where B exists and C does not. Without
799 -v the output is "A verified" because verification stops after a
800 successful redirection if more than one address is generated. However,
801 with -v the child addresses are also verified. Exim was outputting "A
802 failed to verify" and then showing the successful verification for C,
803 with its parentage. It now outputs "B failed to verify", showing B's
804 parentage before showing the successful verification of C.

PH
810PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
811 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
812 they consult the DNS. I had assumed they would set it the way they
813 wanted; and indeed my experiments on Linux seem to show that in some
814 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
815 To be on the safe side, however, I have now made the interface to
816 host_find_byname() similar to host_find_bydns(), with an argument
817 containing the DNS resolver options. The host_find_byname() function now
818 sets these options at its start, just as host_find_bydns() does. The smtp
819 transport options dns_qualify_single and dns_search_parents are passed to
820 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
821 of host_find_byname() use the default settings of RES_DEFNAMES
822 (qualify_single) but not RES_DNSRCH (search_parents).

824PH/17 Applied (a modified version of) Nico Erfurth's patch to make
825 spool_read_header() do less string testing, by means of a preliminary
826 switch on the second character of optional "-foo" lines. (This is
827 overdue, caused by the large number of possibilities that now exist.
828 Originally there were few.) While I was there, I also converted the
829 str(n)cmp tests so they don't re-test the leading "-" and the first
830 character, in the hope this might squeeze out yet more improvement.

PH
832PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
833 flag allowing group syntax was set by the header_syntax check but not
834 turned off, possible causing trouble later; (2) The flag was not being
835 set at all for the header_verify test, causing "group"-style headers to
836 be rejected. I have now set it in this case, and also caused header_
837 verify to ignore an empty address taken from a group. While doing this, I
838 came across some other cases where the code for allowing group syntax
839 while scanning a header line wasn't quite right (mostly, not resetting
840 the flag correctly in the right place). These bugs could have caused
841 trouble for malformed header lines. I hope it is now all correct.

PH
843PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
844 with the "reply" argument non-NULL. The code, however (which originally

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

PH
849PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
850 feature that was used to support insecure browsers during the U.S. crypto
851 embargo. It requires special client support, and Exim is probably the
852 only MTA that supported it -- and would never use it because real RSA is
853 always available. This code has been removed, because it had the bad
854 effect of slowing Exim down by computing (never used) parameters for the
855 RSA_EXPORT functionality.

862 local IP, and the "valid-client-cert option" if a client certificate has
863 been verified.

894
895PH/30 Exim was sometimes attempting to deliver messages that had suffered
896 address errors (4xx response to RCPT) over the same connection as other
897 messages routed to the same hosts. Such deliveries are always "forced",
898 so retry times are not inspected. This resulted in far too many retries
899 for the affected addresses. The effect occurred only when there were more
900 hosts than the hosts_max_try setting in the smtp transport when it had
901 the 4xx errors. Those hosts that it had tried were not added to the list
902 of hosts for which the message was waiting, so if all were tried, there
903 was no problem. Two fixes have been applied:
904
905 (i) If there are any address or message errors in an SMTP delivery, none
906 of the hosts (tried or untried) are now added to the list of hosts
907 for which the message is waiting, so the message should not be a
908 candidate for sending over the same connection that was used for a
909 successful delivery of some other message. This seems entirely
910 reasonable: after all the message is NOT "waiting for some host".
911 This is so "obvious" that I'm not sure why it wasn't done
912 previously. Hope I haven't missed anything, but it can't do any
913 harm, as the worst effect is to miss an optimization.
914
915 (ii) If, despite (i), such a delivery is accidentally attempted, the
916 routing retry time is respected, so at least it doesn't keep
917 hammering the server.

932PH/35 The error "getsockname() failed: connection reset by peer" was being
933 written to the panic log as well as the main log, but it isn't really

935 removed the panic log writing for the ECONNRESET error when getsockname()
936 fails.
937
48c7f9e2
PH
938PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
939 runs only) independently of the message's sender address. This meant
940 that, if the 4xx error was in fact related to the sender, a different
941 message to the same recipient with a different sender could confuse
942 things. In particualar, this can happen when sending to a greylisting
943 server, but other circumstances could also provoke similar problems.
944 I have changed the default so that the retry time for these errors is now
945 based a combination of the sender and recipient addresses. This change
946 can be overridden by setting address_retry_include_sender=false in the
947 smtp transport.

1215PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1216 "Deny" causes Exim to reject the incoming connection with a 554 error.
1217 Unfortunately, if there is a major crisis, such as a disk failure,
1218 tcp-wrappers gives "deny", whereas what one would like would be some
1219 kind of temporary error. A kludge has been added to help with this.
1220 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1221 554 error is used if errno is still zero or contains ENOENT (which occurs
1222 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1223 451 error is used.

1245PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
1246 folder from quota calculations, a direct delivery into this folder messed
1247 up the contents of the maildirsize file. This was because the regex was
1248 used only to exclude .Trash (or whatever) when the size of the mailbox
1249 was calculated. There was no check that a delivery was happening into an
1250 excluded directory. This bug has been fixed by ignoring all quota

1259PH/01 The code for finding all the local interface addresses on a FreeBSD
1260 system running IPv6 was broken. This may well have applied to all BSD
1261 systems, as well as to others that have similar system calls. The broken
1262 code found IPv4 interfaces correctly, but gave incorrect values for the
1263 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1264 that it would not match correctly against @[] and not recognize the IPv6
1265 addresses as local.

1307 generate an autoreply, and therefore failed to obtain an address for the
1308 autoreply, Exim could try to deliver to a non-existent relative file
1309 name, causing unrelated and misleading errors. What now happens is that
1310 it logs this as a hard delivery error, but does not attempt to create a

1328 non-existent - all you got was a failure to exec. I have made two
1329 changes:
1330
1331 (a) Failures to set uid/gid, the current directory, or a process leader
1332 in a subprocess such as that created by queryprogram now generate
1333 suitable debugging ouput when -d is set.
1334

1337 the subprocess without attempting to change uid/gid.

1343 additional section of a DNS packet that returns MX or SRV records.
1344 Instead, it always explicitly searches for A/AAAA records. This avoids
1345 major problems that occur when a DNS server includes only records of one
1346 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1347 fixed another bug: if SRV records were looked up and the corresponding
1348 address records were *not* found in the additional section, the port
1349 values from the SRV records were lost.

1351PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
1359PH/19 When calculating a retry time, Exim used to measure the "time since
1360 failure" by looking at the "first failed" field in the retry record. Now
1361 it does not use this if it is later than than the arrival time of the
1362 message. Instead it uses the arrival time. This makes for better
1363 behaviour in cases where some deliveries succeed, thus re-setting the
1364 "first failed" field. An example is a quota failure for a huge message
1365 when small messages continue to be delivered. Without this change, the
1366 "time since failure" will always be short, possible causing more frequent
1367 delivery attempts for the huge message than are intended.

PH
1464PH/42 The content-scanning code uses fopen() to create files in which to put
1465 message data. Previously it was not paying any attention to the mode of
1466 the files. Exim runs with umask(0) because the rest of the code creates
1467 files with open(), and sets the required mode explicitly. Thus, these
1468 files were ending up world-writeable. This was not a big issue, because,
1469 being within the spool directory, they were not world-accessible. I have
1470 created a function called modefopen, which takes an additional mode
1471 argument. It sets umask(777), creates the file, chmods it to the required
1472 mode, then resets the umask. All the relevant calls to fopen() in the

1510
1511 (i) Exim was not creating retry information for temporary errors given
1512 for individual recipients after the DATA command when the smtp transport
1513 was used in LMTP mode. This meant that they could be retried too
1514 frequently, and not timed out correctly.
1515
1516 (ii) Exim was setting the flag that allows error details to be returned
1517 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1518 recipients that were returned after the DATA command.
1519
1520PH/53 This is related to PH/52, but is more general: for any failing address,
1521 when detailed error information was permitted to be returned to the

1580PH/68 The bounce_return_message and bounce_return_body options were not being
1581 honoured for bounces generated during the reception of non-SMTP messages.
1582 In particular, this applied to messages rejected by the ACL. This bug has
1583 been fixed. However, if bounce_return_message is true and bounce_return_
1584 body is false, the headers that are returned for a non-SMTP message
1585 include only those that have been read before the error was detected.

1594PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1595 function verify_get_ident() calls ip_connect() to connect a socket, but
1596 if the "connect()" function timed out, ip_connect() used to close the
1597 socket. However, verify_get_ident() also closes the socket later, and in
1598 between Exim writes to the log, which may get opened at this point. When
1599 the socket was closed in ip_connect(), the log could get the same file
1600 descriptor number as the socket. This naturally causes chaos. The fix is
1601 not to close the socket in ip_connect(); the socket should be closed by
1602 the function that creates it. There was only one place in the code where
1603 this was missing, in the iplookup router, which I don't think anybody now
1604 uses, but I've fixed it anyway.

1626 not a single digit.
1627
1628 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1629 string.
1630
1631 (3) Reset the variables that are obtained from the first argument of
1632 ${prvscheck and used in the second argument before leaving the code,
1633 because their memory is reclaimed, so using them afterwards may do
1634 silly things.
1635
1636 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1637 one (it's much easier than Tom thought :-).
1638
1639 (5) Because of (4), we can now allow for the use of $prvscheck_result
1640 inside the third argument.

1655 may be more than one such address. If so, they are comma-separated, like

1660PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1661 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1662 not being looked up in the rDNS to get a host name, Exim was showing the
1663 IP address twice in Received: lines, even though the IP addresses were
1664 identical. For example:
1665
1666 Received: from [1.2.3.4] (helo=[1.2.3.4])
1667
1668 However, if the real host name was known, it was omitting the HELO data
1669 if it matched the actual IP address. This has been tidied up so that it
1670 doesn't show the same IP address twice.

1696PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

1698
1699 Auto-submitted: auto-generated
1700
1701 in the messages that it generates (bounce messages and others, such as
1702 warnings). In the case of bounce messages for non-SMTP mesages, there was
1703 also a typo: it was using "Auto_submitted" (underscore instead of
1704 hyphen). Since every message generated by Exim is necessarily in response
1705 to another message, thes have all been changed to:
1706
1707 Auto-Submitted: auto-replied
1708
1709 in accordance with these statements in the RFC:
1710
1711 The auto-replied keyword:
1712
1713 - SHOULD be used on messages sent in direct response to another
1714 message by an automatic process,
1715
1716 - MUST NOT be used on manually-generated messages,

1719 Disposition Notifications (MDNs),

1759PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1760 canonical form (as documented). However, after a host name lookup from
1761 the IP address, check_host() was doing a simple string comparison with
1762 addresses acquired from the DNS when checking that the found name did
1763 have the original IP as one of its addresses. Since any found IPv6
1764 addresses are likely to be in abbreviated form, the comparison could
1765 fail. Luckily, there already exists a function for doing the comparison
1766 by converting both addresses to binary, so now that is used instead of
1767 the text comparison.

2065 with the definition in sysexits.h (which is #included earlier).
2066 Fortunately, Exim does not actually use EX_OK. The code used to try to
2067 preserve the sysexits.h value, by assumimg that macro definitions were
2068 scanned for macro replacements. I have been disabused of this notion,

2075 would take for ever. The timeout is now adjusted when this happens. It
2076 doesn't have to be particularly precise.

2284
2285PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2286 that changes the way the GnuTLS parameters are stored in the cache file.
2287 The new format can be generated externally. For backward compatibility,
2288 if the data in the cache doesn't make sense, Exim assumes it has read an
2289 old-format file, and it generates new data and writes a new file. This
2290 means that you can't go back to an older release without removing the
2291 file.
2292
2293PH/03 A redirect router that has both "unseen" and "one_time" set does not
2294 work if there are any delivery delays because "one_time" forces the
2295 parent to be marked "delivered", so its unseen clone is never tried
2296 again. For this reason, Exim now forbids the simultaneous setting of
2297 these two options.
2298
2299PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2300 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2301 entry if you want to know the details. The fix, however, neglected to
2302 consider the case when local delivery batching is involved. The test for
2303 "previously delivered" was not happening when checking to see if an
2304 address could be batched with a previous (undelivered) one; under
2305 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2306 address.

2308PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2311PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2312 header_syntax) but Exim was just ignoring anything given after a slash.
2313 In particular, this caused confusion with an attempt to use "verify =
2314 reverse_host_lookup/defer_ok". An error is now given when options are
2315 supplied for verify items that do not have them. (Maybe reverse_host_
2316 lookup should have a defer_ok option, but that's a different point.)
2317
2318PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2371 the file with the wrong ownership). There was no test for failure of this

2377PH/20 When checking for unexpected SMTP input at connect time (before writing
2378 the banner), Exim was not dealing correctly with a non-positive return
2379 from the read() function. If the client had disconnected by this time,
2380 the result was a log entry for a synchronization error with an empty
2381 string after "input=" when read() returned zero. If read() returned -1
2382 (an event I could not check), uninitialized data bytes were printed.
2383 There were reports of junk text (parts of files, etc) appearing after
2384 "input=".

2391PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then

PH
2394PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2395 hadn't been configured. The fix is from Juergen Kreileder, who
2396 understands it better than I do:
2397
2398 "Here's what I see happening with three configured cyrus_sasl
2399 authenticators configured (plain, login, cram-md5):
2400
2401 On startup auth_cyrus_sasl_init() gets called for each of these.
2402 This means three calls to sasl_listmech() without a specified mech_list.
2403 => SASL tests which mechs of all available mechs actually work
2404 => three warnings about OTP not working
2405 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2406
2407 With the patch, sasl_listmech() also gets called three times. But now
2408 SASL's mech_list option is set to the server_mech specified in the the
2409 authenticator. Or in other words, the answer from sasl_listmech()
2410 gets limited to just the mech you're testing for (which is different
2411 for each call.)
2412 => the return list contains just 'plain' or 'login', 'cram-md5' or
2413 nothing depending on the value of ob->server_mech.
2414
2415 I've just tested the patch: Authentication still works fine,
2416 unavailable mechs specified in the exim configuration are still
2417 caught, and the auth.log warnings about OTP are gone."

PH
2481PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2482 the grounds that routing the same address twice would always produce the
2483 same answer. This might have been true once, but it is certainly no
2484 longer true now. Routing a child address may depend on the previous
2485 routing that produced that child. Some complicated redirection strategies
2486 went wrong when messages had multiple recipients, and made Exim's
2487 behaviour dependent on the order in which the addresses were given.
2488
2489 I have moved the duplicate checking until after the routing is complete.
2490 Exim scans the addresses that are assigned to local and remote
2491 transports, and removes any duplicates. This means that more work will be
2492 done, as duplicates will always all be routed, but duplicates are
2493 presumably rare, so I don't expect this is of any significance.
2494
2495 For deliveries to pipes, files, and autoreplies, the duplicate checking
2496 still happens during the routing process, since they are not going to be
2497 routed further.

2542 consistency with the overall process timeout, these timeouts are now
2543 treated as errors, giving rise to delivery failures by default. However,
2544 there is now a new Boolean option for the pipe transport called
2545 timeout_defer, which, if set TRUE, converts the failures into defers for
2546 both kinds of timeout. A transport filter timeout is now identified in

2556A note about Exim versions 4.44 and 4.50
2557----------------------------------------
2558
2559Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2560changes of various kinds. As a consequence, a big documentation update was
2561needed. This delayed the release for rather longer than seemed good, especially
2562in the light of a couple of (minor) security issues. Therefore, the changes
2563that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2564release. So 4.44 and 4.50 are in effect two different branches that both start
2565from 4.43.
2566
2567I have left the 4.50 change log unchanged; it contains all the changes since
25684.43. The change log for 4.44 is below; many of its items are identical to
2569those for 4.50. This seems to be the most sensible way to preserve the
2570historical information.

2588 5. There are several places where Exim runs a non-Exim command in a
2589 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2590 was being done only for the command run by the queryprogram router. It is
2591 now done for all such subprocesses. The other cases are: ${run, transport
2592 filters, and the commands run by the lmtp and pipe transports.

2597 descriptors. Exim was using setrlimit() to set 1000 as a large value
2598 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2599 systems. I've change it so that if it can't get 1000, it tries for 256.

2647 ignore_target_hosts.
2648
264923. When checking ignore_target_hosts for an ipliteral router, no host name was
2650 being passed; this would have caused $sender_host_name to have been used if
2651 matching the list had actually called for a host name (not very likely,
2652 since this list is usually IP addresses). A host name is now passed as
2653 "[x.x.x.x]".
2654

PH
265524. Changed the calls that set up the SIGCHLD handler in the daemon to use the

2657 modern systems) in an attempt to fix a rare and obscure crash bug.
2658
265925. Narrowed the window for a race in the daemon that could cause it to ignore

PH
267329. In an address list, if the pattern was not a regular expression, an empty
2674 subject address (from a bounce message) matched only if the pattern was an
2675 empty string. Non-empty patterns were not even tested. This was the wrong
2676 because it is perfectly reasonable to use an empty address as part of a
2677 database query. An empty address is now tested by patterns that are
2678 lookups. However, all the other forms of pattern expect the subject to
2679 contain a local part and a domain, and therefore, for them, an empty
2680 address still always fails if the pattern is not itself empty.
2681
d8ef3577
PH
268230. Exim went into a mad DNS loop when attempting to do a callout where the
2683 host was specified on an smtp transport, and looking it up yielded more
2684 than one IP address.

5cb8cbc6
PH
268631. Re-factored the code for checking spool and log partition space into a
2687 function that finds that data and another that does the check. The former

2689 $spool_inodes, and $log_inodes.

PH
269132. The RFC2047 encoding function was originally intended for short strings
2692 such as real names; it was not keeping to the 75-character limit for
2693 encoded words that the RFC imposes. It now respects the limit, and
2694 generates multiple encoded words if necessary. To be on the safe side, I
2695 have increased the buffer size for the ${rfc2047: expansion operator from
2696 1024 to 2048 bytes.
2697
063b1e99
PH
269833. It is now permitted to omit both strings after an "if" condition; if the
2699 condition is true, the result is "true". As before, when the second string
2700 is omitted, a false condition yields an empty string. This makes it less
2701 cumbersome to write custom ACL and router conditions.
2702
652e1b65
PH
270334. Failure to deliver a bounce message always caused it to be frozen, even if
2704 there was an errors_to setting on the router. The errors_to setting is now
2705 respected.

PH
271136. The table in the code that translates DNS record types into text (T_A to
2712 "A" for instance) was missing entries for NS and CNAME. It is just possible
2713 that this could have caused confusion if both these types were looked up
2714 for the same domain, because the text type is used as part of Exim's
2715 per-process caching. But the chance of anyone hitting this buglet seems
2716 very small.

PH
271837. The dnsdb lookup has been extended in a number of ways.

2754 < 0 before doing a fflush(). This bug looks as though it goes back to the

2775 AES128, 3DES, ARCFOUR128.

PH
278052. Exim crashed if a remote delivery caused a very long error message to be
2781 recorded - for instance if somebody sent an entire SpamAssassin report back
2782 as a large number of 550 error lines. This bug was coincidentally fixed by
2783 increasing the size of one of Exim's internal buffers (big_buffer) that
2784 happened as part of the Exiscan merge. However, to be on the safe side, I
2785 have made the code more robust (and fixed the comments that describe what
2786 is going on).
2787

PH
278853. Now that there can be additional text after "Completed" in log lines (if
2789 the queue_time_overall log selector is set), a one-byte patch to exigrep
2790 was needed to allow it to recognize "Completed" as not the last thing in
2791 the line.

PH
279354. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2794 patch that reportedly fixes this has been added. I am not expert enough to
2795 create a test for it. This is what the patch creator wrote:
2796
2797 "I found a little strange behaviour of ldap code when working with
2798 Windows 2003 AD Domain, where users was placed in more than one
2799 Organization Units. When I tried to give exim partial DN, the exit code
2800 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2801 But simultaneously result of request was absolutely normal ldap result,
2802 so I produce this patch..."
2803
3295e65b
PH
2804 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2805 REFERENCE, so I have modified the code to exclude the patch when that macro
2806 is not defined.
2807

PH
280855. Some experimental protocols are using DNS PTR records for new purposes. The
2809 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2810 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2811 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
281958. The exicyclog utility now does better if the number of log files to keep

PH
282259. Two changes related to the smtp_active_hostname option:
2823
2824 (1) $smtp_active_hostname is now available as a variable.
2825 (2) The default for smtp_banner uses $smtp_active_hostname instead
2826 of $primary_hostname.
2827
b975ba52
PH
282860. The host_aton() function is supposed to be passed a string that is known
2829 to be a valid IP address. However, in the case of IPv6 addresses, it was
2830 not checking this. This is a hostage to fortune. Exim now panics and dies
2831 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2832 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2833 components; fortuitously, this particular loophole had already been fixed
2834 by change 4.50/55 above.
2835
2836 If there are any other similar loopholes, the new check in host_aton()
2837 itself should stop them being exploited. The report I received stated that
2838 data on the command line could provoke the exploit when Exim was running as
2839 exim, but did not say which command line option was involved. All I could
2840 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2841 running as the user.

PH
285263. The daemon start-up calls getloadavg() while still root for those OS that
2853 need the first call to be done as root, but it missed one case: when
2854 deliver_queue_load_max is set with deliver_drop_privilege. This is
2855 necessary for the benefit of the queue runner, because there is no re-exec
2856 when deliver_drop_privilege is set.

2859 This has been fixed.
2860
60dc5e56
PH
286165. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2862 was in use, was not putting the data itself into the right store pool;
2863 consequently, it could be overwritten for a subsequent message in the same
2864 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2865 the caching.)

PH
286766. Added hosts_max_try_hardlimit to the smtp transport, default 50.

PH
286967. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2870 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2871 the function were treating the return as a boolean value, which happened to
2872 work because 0=false and not-0=true, but is not correct code.
2873
7e634d24
PH
287468. The host_aton() function was not handling scoped IPv6 addresses (those
2875 with, for example, "%eth0" on the end) correctly.
2876

PH
287769. Fixed some compiler warnings in acl.c for the bitmaps specified with
2878 negated items (that is, ~something) in unsigned ints. Some compilers
2879 apparently mutter when there is no cast.
2880
6729cf78
PH
288170. If an address verification called from an ACL failed, and did not produce a
2882 user-specific message (i.e. there was only a "system" message), nothing was
2883 put in $acl_verify_message. In this situation, it now puts the system
2884 message there.
2885
00f00ca5
PH
288671. Change 4.23/11 added synchronization checking at the start of an SMTP
2887 session; change 4.31/43 added the unwanted input to the log line - except
2888 that it did not do this in the start of session case. It now does.
2889
c9bdd01c
PH
289072. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2891 This is wrong and can cause the other end to generate a synchronization
2892 error if it is another Exim or anything else that does the synchronization
2893 check. A QUIT command is no longer sent after a timeout.

PH
289874. The defer_ok option of callout verification was not working if it was used
2899 when verifying addresses in header lines, that is, for this case:
2900
2901 verify = header_sender/callout=defer_ok
2902
76a2d7ba
PH
290375. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2904 those file descriptors could be used for SMTP connections. If anything
2905 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2906 could be sent to the SMTP client, causing chaos. The daemon now opens
2907 stdin, stdout, and stderr to /dev/null when it puts itself into the
2908 background.
2909
291076. Arrange for output from Perl's "warn" command to be written to Exim's main
2911 log by default. The user can override this with suitable Perl magic.
2912
04f7d5b9
PH
291377. The use of log_message on a "discard" ACL verb, which is supposed to add to
2914 the log message when discard triggers, was not working for the DATA ACL or
2915 for the non-SMTP ACL.
2916

PH
291778. Error message wording change in sieve.c.
2918
bb6e88ff
PH
291979. If smtp_accept_max_per_host was set, the number of connections could be
2920 restricted to fewer than expected, because the daemon was trying to set up
2921 a new connection before checking whether the processes handling previous
2922 connections had finished. The check for completed processes is now done
2923 earlier. On busy systems, this bug wouldn't be noticed because something
2924 else would have woken the daemon, and it would have reaped the completed
2925 process earlier.
2926
1e70f85b
PH
292780. If a message was submitted locally by a user whose login name contained one
2928 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2929 It caused a spool format error. I have fixed the spool reading code. A
2930 related problem was that the "from" clause in the Received: line became
2931 illegal because of the space(s). It is now covered by ${quote_local_part.

2947----------------------------------------------------
2948See the note above about the 4.44 and 4.50 releases.
2949----------------------------------------------------
2950
2951
2952Exim version 4.44
2953-----------------
2954
2955 1. Change 4.43/35 introduced a bug that caused file counts to be
2956 incorrectly computed when quota_filecount was set in an appendfile
2957 transport
2958
2959 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2960 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2961 place.
2962
2963 3. Give more explanation in the error message when the command for a transport
2964 filter fails to execute.
2965
2966 4. There are several places where Exim runs a non-Exim command in a
2967 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2968 was being done only for the command run by the queryprogram router. It is
2969 now done for all such subprocesses. The other cases are: ${run, transport
2970 filters, and the commands run by the lmtp and pipe transports.
2971
2972 5. Some older OS have a limit of 256 on the maximum number of file
2973 descriptors. Exim was using setrlimit() to set 1000 as a large value
2974 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2975 systems. I've change it so that if it can't get 1000, it tries for 256.
2976
2977 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2978 was an oversight, and furthermore, ever since the addition of extra
2979 controls (e.g. 4.43/32), the checks on when to allow different forms of
2980 "control" were broken. There should now be diagnostics for all cases when a
2981 control that does not make sense is encountered.
2982
2983 7. $recipients is now available in the predata ACL (oversight).
2984
2985 8. Tidy the search cache before the fork to do a delivery from a message
2986 received from the command line. Otherwise the child will trigger a lookup
2987 failure and thereby defer the delivery if it tries to use (for example) a
2988 cached ldap connection that the parent has called unbind on.
2989
2990 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2991 of $address_data from the recipient verification was clobbered by the
2992 sender verification.
2993
299410. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
2995 was its contents. (It was OK if the option was not defined at all.)
2996
299711. A "Completed" log line is now written for messages that are removed from
2998 the spool by the -Mrm option.
2999
300012. $host_address is now set to the target address during the checking of
3001 ignore_target_hosts.
3002
300313. When checking ignore_target_hosts for an ipliteral router, no host name was
3004 being passed; this would have caused $sender_host_name to have been used if
3005 matching the list had actually called for a host name (not very likely,
3006 since this list is usually IP addresses). A host name is now passed as
3007 "[x.x.x.x]".
3008
300914. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3010 code that specifies a non-restarting handler (typically sigaction() in
3011 modern systems) in an attempt to fix a rare and obscure crash bug.
3012
301315. Narrowed the window for a race in the daemon that could cause it to ignore
3014 SIGCHLD signals. This is not a major problem, because they are used only to
3015 wake it up if nothing else does.
3016
301716. A malformed maildirsize file could cause Exim to calculate negative values
3018 for the mailbox size or file count. Odd effects could occur as a result.
3019 The maildirsize information is now recalculated if the size or filecount
3020 end up negative.
3021
302217. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3023 support for a long time. Removed HAVE_SYS_VFS_H.
3024
ea3a6f44 302518. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3026
302719. Allow an empty sender to be matched against a lookup in an address list.
3028 Previously the only cases considered were a regular expression, or an
3029 empty pattern.
3030
303120. Exim went into a mad DNS lookup loop when doing a callout where the
3032 host was specified on the transport, if the DNS lookup yielded more than
3033 one IP address.
3034
ea3a6f44
NM
303521. The RFC2047 encoding function was originally intended for short strings
3036 such as real names; it was not keeping to the 75-character limit for
3037 encoded words that the RFC imposes. It now respects the limit, and
3038 generates multiple encoded words if necessary. To be on the safe side, I
3039 have increased the buffer size for the ${rfc2047: expansion operator from
3040 1024 to 2048 bytes.
bbe902f0 3041
ea3a6f44
NM
304222. Failure to deliver a bounce message always caused it to be frozen, even if
3043 there was an errors_to setting on the router. The errors_to setting is now
3044 respected.
bbe902f0
PH
3045
304623. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3047 canonical form (fully expanded) before being placed in
3048 $sender_host_address.
3049
305024. Updated eximstats to version 1.33
3051
ea3a6f44
NM
305225. Include certificate and key file names in error message when GnuTLS fails
3053 to set them up, because the GnuTLS error message doesn't include the name
3054 of the failing file when there is a problem reading it.
bbe902f0
PH
3055
305626. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3057 As per change 25.
bbe902f0 3058
ea3a6f44
NM
305927. Reset the locale to "C" after calling embedded Perl, in case it was changed
3060 (this can affect the format of dates).
bbe902f0 3061
ea3a6f44
NM
306228. exim_tidydb, when checking for the continued existence of a message for
3063 which it has found a message-specific retry record, was not finding
3064 messages that were in split spool directories. Consequently, it was
3065 deleting retry records that should have stayed in existence.
bbe902f0
PH
3066
306729. eximstats updated to version 1.35
3068 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3069 1.35 - bugfix such that pie charts by volume are generated correctly

307130. The SPA authentication driver was not abandoning authentication and moving
3072 on to the next authenticator when an expansion was forced to fail,
3073 contradicting the general specification for all authenticators. Instead it
3074 was generating a temporary error. It now behaves as specified.

307631. The default ordering of permitted cipher suites for GnuTLS was pessimal

3092 keys for these records are domain names, not reversed IP addresses. The

309734. The host_aton() function is supposed to be passed a string that is known
3098 to be a valid IP address. However, in the case of IPv6 addresses, it was
3099 not checking this. This is a hostage to fortune. Exim now panics and dies

3106 itself should stop them being exploited. The report I received stated that
3107 data on the command line could provoke the exploit when Exim was running as

3131 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3132 < 0 before doing a fflush(). This bug looks as though it goes back to the
3133 introduction of TLS in release 3.20, but "sometimes" must have been rare

3137Exim version 4.43
3138-----------------
3139
3140 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3141 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3142 Now it returns an integer. A number of calls were still expecting a T/F
3143 return. Fortuitously, in all cases, the tests worked in OK situations,
3144 which is the norm. However, things would have gone wrong on any write
3145 failures on the smtp file descriptor. This function is used when sending
3146 messages over SMTP and also when doing verify callouts.
3147
3148 2. When Exim is called to do synchronous delivery of a locally submitted
3149 message (the -odf or -odi options), it no longer closes stderr before doing
3150 the delivery.
3151
3152 3. Implemented the mua_wrapper option.
3153
3154 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3155
3156 5. Implemented the functions header_remove(), header_testname(),
3157 header_add_at_position(), and receive_remove_recipient(), and exported them
3158 to local_scan().
3159
3160 6. If an ACL "warn" statement specified the addition of headers, Exim already
3161 inserted X-ACL-Warn: at the start if there was no header name. However, it
3162 was not making this test for the second and subsequent header lines if
3163 there were newlines in the string. This meant that an invalid header could
3164 be inserted if Exim was badly configured.
3165
3166 7. Allow an ACL "warn" statement to add header lines at the start or after all
3167 the Received: headers, as well as at the end.
3168
3169 8. Added the rcpt_4xx retry error code.
3170
3171 9. Added postmaster_mailfrom=xxx to callout verification option.
3172
317310. Added mailfrom=xxxx to the callout verification option, for verify=
3174 header_sender only.
3175
317611. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3177 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3178
317912. Inserted some casts to stop certain compilers warning when using pointer
3180 differences as field lengths or precisions in printf-type calls (mostly
3181 affecting debugging statements).
3182
318313. Added optional readline() support for -be (dynamically loaded).
3184
318514. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3186 same clock tick as a message's arrival, so that its received time was the
3187 same as the "first fail" time on the retry record, and that message
3188 remained on the queue past the ultimate address timeout, every queue runner
3189 would try a delivery (because it was past the ultimate address timeout) but
3190 after another failure, the ultimate address timeout, which should have then
3191 bounced the address, did not kick in. This was a "< instead of <=" error;
3192 in most cases the first failure would have been in the next clock tick
3193 after the received time, and all would be well.
3194
319515. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3196 being recognized when the domain list was tested by the match_domain
3197 condition in an expansion string.
3198
319916. Added the ${str2b64: operator.
3200
320117. Exim was always calling setrlimit() to set a large limit for the number of
3202 processes, without checking whether the existing limit was already
3203 adequate. (It did check for the limit on file descriptors.) Furthermore,
3204 errors from getrlimit() and setrlimit() were being ignored. Now they are
3205 logged to the main and panic logs, but Exim does carry on, to try to do its
3206 job under whatever limits there are.
3207
320818. Imported PCRE 5.0.
3209
321019. Trivial typo in log message " temporarily refused connection" (the leading
3211 space).
3212
321320. If the log selector return_path_on_delivery was set and an address was
3214 redirected to /dev/null, the delivery process crashed because it assumed
3215 that a return path would always be set for a "successful" delivery. In this
3216 case, the whole delivery is bypassed as an optimization, and therefore no
3217 return path is set.
3218
321921. Internal re-arrangement: the function for sending a challenge and reading
3220 a response while authentication was assuming a zero-terminated challenge
3221 string. It's now changed to take a pointer and a length, to allow for
3222 binary data in such strings.
3223
322422. Added the cyrus_sasl authenticator (code supplied by MBM).
3225
322623. Exim was not respecting finduser_retries when seeking the login of the
3227 uid under which it was called; it was always trying 10 times. (The default
3228 setting of finduser_retries is zero.) Also, it was sleeping after the final
3229 failure, which is pointless.
3230
323124. Implemented tls_on_connect_ports.
3232
323325. Implemented acl_smtp_predata.
3234
323526. If the domain in control=submission is set empty, Exim assumes that the
3236 authenticated id is a complete email address when it generates From: or
3237 Sender: header lines.
3238
323927. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3240 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3241 chown and chgrp in /bin and hostname in /usr/bin.
3242
324328. Exim was keeping the "process log" file open after each use, just as it
3244 does for the main log. This opens the possibility of it remaining open for
3245 long periods when the USR1 signal hits a daemon. Occasional processlog
3246 errors were reported, that could have been caused by this. Anyway, it seems
3247 much more sensible not to leave this file open at all, so that is what now
3248 happens.
3249
325029. The long-running daemon process does not normally write to the log once it
3251 has entered its main loop, and it closes the log before doing so. This is
3252 so that log files can straightforwardly be renamed and moved. However,
3253 there are a couple of unusual error situations where the daemon does write
3254 log entries, and I had neglected to close the log afterwards.
3255
325630. The text of an SMTP error response that was received during a remote
3257 delivery was being truncated at 512 bytes. This is too short for some of
3258 the long messages that one sometimes sees. I've increased the limit to
3259 1024.
3260
326131. It is now possible to make retry rules that apply only when a message has a
3262 specific sender, in particular, an empty sender.
3263
326432. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3265 it possible to be selective about when SMTP synchronization is enforced.
3266
326733. Added "control = caseful_local_part" and "control = "caselower_local_part".
3268
326932. Implemented hosts_connection_nolog.
3270
327133. Added an ACL for QUIT.
3272
327334. Setting "delay_warning=" to disable warnings was not working; it gave a
3274 syntax error.
3275
327635. Added mailbox_size and mailbox_filecount to appendfile.
3277
327836. Added control = no_multiline_responses to ACLs.
3279
328037. There was a bug in the logic of the code that waits for the clock to tick
3281 in the case where the clock went backwards by a substantial amount such
3282 that the microsecond fraction of "now" was more than the microsecond
3283 fraction of "then" (but the whole seconds number was less).
3284
328538. Added support for the libradius Radius client library this is found on
3286 FreeBSD (previously only the radiusclient library was supported).
3287
3288
3289Exim version 4.42
3290-----------------
3291
3292 1. When certain lookups returned multiple values in the form name=value, the
3293 quoting of the values was not always being done properly. Specifically:
3294 (a) If the value started with a double quote, but contained no whitespace,
3295 it was not quoted.
3296 (b) If the value contained whitespace other than a space character (i.e.
3297 tabs or newlines or carriage returns) it was not quoted.
3298 This fix has been applied to the mysql and pgsql lookups by writing a
3299 separate quoting function and calling it from the lookup code. The fix
3300 should probably also be applied to nisplus, ibase and oracle lookups, but
3301 since I cannot test any of those, I have not disturbed their existing code.
3302
3303 2. A hit in the callout cache for a specific address caused a log line with no
3304 reason for rejecting RCPT. Now it says "Previous (cached) callout
3305 verification failure".
3306
3307 3. There was an off-by-one bug in the queryprogram router. An over-long
3308 return line was truncated at 256 instead of 255 characters, thereby
3309 overflowing its buffer with the terminating zero. As well as fixing this, I
3310 have increased the buffer size to 1024 (and made a note to document this).
3311
3312 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3313 when Exim is waiting for an SMTP response from a remote server, Exim
3314 restarts its select() call on the socket, thereby resetting its timeout.
3315 This is not a problem when such interrupts are rare. Somebody set up a cron
3316 job to run exiwhat every 2 minutes, which is less than the normal select()
3317 timeout (5 or 10 minutes). This meant that the select() timeout never
3318 kicked in because it was always reset. I have fixed this by comparing the
3319 time when an interrupt arrives with the time at the start of the first call
3320 to select(). If more time than the timeout has elapsed, the interrupt is
3321 treated as a timeout.
3322
3323 5. Some internal re-factoring in preparation for the addition of Sieve
3324 extensions (by MH). In particular, the "personal" test is moved to a
3325 separate function, and given an option for scanning Cc: and Bcc: (which is
3326 not set for Exim filters).
3327
3328 6. When Exim created an email address using the login of the caller as the
3329 local part (e.g. when creating a From: or Sender: header line), it was not
3330 quoting the local part when it contained special characters such as @.
3331
3332 7. Installed new OpenBSD configuration files.
3333
3334 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3335 try to make them clearer.
3336
3337 9. Callout options, other than the timeout value, were being ignored when
3338 verifying sender addresses in header lines. For example, when using
3339
3340 verify = header_sender/callout=no_cache
3341
3342 the cache was (incorrectly) being used.
3343
334410. Added a missing instance of ${EXE} to the exim_install script; this affects
3345 only the Cygwin environment.
3346
334711. When return_path_on_delivery was set as a log selector, if different remote
3348 addresses in the same message used different return paths and parallel
3349 remote delivery occurred, the wrong values would sometimes be logged.
3350 (Whenever a remote delivery process finished, the return path value from
3351 the most recently started remote delivery process was logged.)
3352
335312. RFC 3848 specifies standard names for the "with" phrase in Received: header
3354 lines when AUTH and/or TLS are in use. This is the "received protocol"
3355 field. Exim used to use "asmtp" for authenticated SMTP, without any
3356 indication (in the protocol name) for TLS use. Now it follows the RFC and
3357 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3358 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3359 names appear in log lines as well as in Received: header lines.
3360
336113. Installed MH's patches for Sieve to add the "copy" and "vacation"
3362 extensions, and comparison tests, and to fix some bugs.
3363
336414. Changes to the "personal" filter test:
3365
3366 (1) The test was buggy in that it was just doing the equivalent of
3367 "contains" tests on header lines. For example, if a user's address was
3368 anne@some.where, the "personal" test would incorrectly be true for
3369
3370 To: susanne@some.where
3371
3372 This test is now done by extracting each address from the header in turn,
3373 and checking the entire address. Other tests that are part of "personal"
3374 are now done using regular expressions (for example, to check local parts
3375 of addresses in From: header lines).
3376
3377 (2) The list of non-personal local parts in From: addresses has been
3378 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3379 taken from the Sieve specification recommendations.
3380
3381 (3) If the message contains any header line starting with "List-" it is
3382 treated as non-personal.
3383
3384 (4) The test for "circular" in the Subject: header line has been removed
3385 because it now seems ill-conceived.
3386
338715. Minor typos in src/EDITME comments corrected.
3388
338916. Installed latest exipick from John Jetmore.
3390
339117. If headers_add on a router specified a text string that was too long for
3392 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3393 of string_sprintf() is now avoided.
3394
339518. $message_body_size was not set (it was always zero) when running the DATA
3396 ACL and the local_scan() function.
3397
339819. For the "mail" command in an Exim filter, no default was being set for
3399 the once_repeat time, causing a random time value to be used if "once" was
3400 specified. (If the value happened to be <= 0, no repeat happened.) The
3401 default is now 0s, meaning "never repeat". The "vacation" command was OK
3402 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3403 (I found it when inspecting the code).
3404
340520. There is now an overall timeout for performing a callout verification. It
3406 defaults to 4 times the callout timeout, which applies to individual SMTP
3407 commands during the callout. The overall timeout applies when there is more
3408 than one host that can be tried. The timeout is checked before trying the
3409 next host. This prevents very long delays if there are a large number of
3410 hosts and all are timing out (e.g. when the network connections are timing
3411 out). The value of the overall timeout can be changed by specifying an
3412 additional sub-option for "callout", called "maxwait". For example:
3413
3414 verify = sender/callout=5s,maxwait=20s
3415
341621. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3417 to the end before writing, but this should make it even safer).
3418
341922. Exim was forgetting that it had advertised PIPELINING for the second and
3420 subsequent messages on an SMTP connection. It was also not resetting its
3421 memory on STARTTLS and an internal HELO.
3422
342323. When Exim logs an SMTP synchronization error within a session, it now
3424 records whether PIPELINING has been advertised or not.
3425
342624. Added 3 instances of "(long int)" casts to time_t variables that were being
3427 formatted using %ld, because on OpenBSD (and perhaps others), time_t is int
3428 rather than long int.
3429
343025. Installed the latest Cygwin configuration files from the Cygwin maintainer.
3431
343226. Added the never_mail option to autoreply.
3433
3434
3435Exim version 4.41
3436-----------------
3437
3438 1. A reorganization of the code in order to implement 4.40/8 caused a daemon
3439 crash if the getsockname() call failed; this can happen if a connection is
3440 closed very soon after it is established. The problem was simply in the
3441 order in which certain operations were done, causing Exim to try to write
3442 to the SMTP stream before it had set up the file descriptor. The bug has
3443 been fixed by making things happen in the correct order.
3444
3445
3446Exim version 4.40
3447-----------------
3448
