TK
320TK/01 Add preliminary DKIM support. Currently requires a forked version of
321 ALT-N's libdkim that I have put here:
322 http://duncanthrax.net/exim-experimental/
323
324 Note to Michael Haardt: I had to rename some vars in sieve.c. They
325 were called 'true' and it seems that C99 defines that as a reserved
326 keyword to be used with 'bool' variable types. That means you could
327 not include C99-style headers which use bools without triggering
328 build errors in sieve.c.

343Exim version 4.68
344-----------------
345
346PH/01 Another patch from the Sieve maintainer.
347
6a3bceb1
PH
348PH/02 When an IPv6 address is converted to a string for single-key lookup
349 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
350 dots are used instead of colons so that keys in lsearch files need not
351 contain colons. This was done some time before quoting was made available
352 in lsearch files. However, iplsearch files do require colons in IPv6 keys
353 (notated using the quote facility) so as to distinguish them from IPv4
354 keys. This meant that lookups for IP addresses in host lists did not work
355 for iplsearch lookups.
356
357 This has been fixed by arranging for IPv6 addresses to be expressed with
358 colons if the lookup type is iplsearch. This is not incompatible, because
359 previously such lookups could never work.
360
361 The situation is now rather anomolous, since one *can* have colons in
362 ordinary lsearch keys. However, making the change in all cases is
363 incompatible and would probably break a number of configurations.

365TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
366 version.
367

MH
368MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
369 conversion specification without a maximum field width, thereby enabling
370 a rogue spamd server to cause a buffer overflow. While nobody in their
371 right mind would setup Exim to query an untrusted spamd server, an
372 attacker that gains access to a server running spamd could potentially
373 exploit this vulnerability to run arbitrary code as the Exim user.

375TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
376 $primary_hostname instead of what libspf2 thinks the hosts name is.
377
0f2cbd1b
MH
378MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
379 a directory entry by the name of the lookup key. Previously, if a
380 symlink pointed to a non-existing file or a file in a directory that
381 Exim lacked permissions to read, a lookup for a key matching that
382 symlink would fail. Now it is enough that a matching directory entry
383 exists, symlink or not. (Bugzilla 503.)

566PH/29 SMTP synchronization checks are implemented when a command is read -
567 there is a check that no more input is waiting when there shouldn't be

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

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

663
664PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
665 fixed by 4.65/MH/01 (is this a record?) are fixed:
666
667 (i) An empty string was always treated as zero by the numeric comparison
668 operators. This behaviour has been restored.
669
670 (ii) It is documented that the numeric comparison operators always treat
671 their arguments as decimal numbers. This was broken in that numbers
672 starting with 0 were being interpreted as octal.
673
674 While fixing these problems I realized that there was another issue that
675 hadn't been noticed. Values of message_size_limit (both the global option
676 and the transport option) were treated as octal if they started with 0.
677 The documentation was vague. These values are now always treated as
678 decimal, and I will make that clear in the documentation.

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

703TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a

2b1c6e3a
PH
722PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
723 callout verification, Exim cached a "reject" for the entire domain. This
724 is correct for most verifications, but it is not correct for a recipient
725 verification with use_sender or use_postmaster set, because in that case
726 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
727 case of MAIL FROM:<> rejection from other early rejections (e.g.
728 rejection of HELO). When verifying a recipient using a non-null MAIL
729 address, the cache is ignored if it shows MAIL FROM:<> rejection.
730 Whatever the result of the callout, the value of the domain cache is
731 left unchanged (for any other kind of callout, getting as far as trying
732 RCPT means that the domain itself is ok).

766PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

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

14aa5a05 775PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 776 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
777 (a) The code assumed that strncpy() returns a negative number on buffer
778 overflow, which isn't the case. Replaced with Exim's string_format()
779 function.
780 (b) There were several signed/unsigned issues. I just did the minimum
781 hacking in of casts. There is scope for a larger refactoring.
782 (c) The code used strcasecmp() which is not a standard C function.
783 Replaced with Exim's strcmpic() function.
784 (d) The code set only $1; it now sets $auth1 as well.
785 (e) A simple test gave the error "authentication client didn't specify
786 service in request". It would seem that Dovecot has changed its
787 interface. Fortunately there's a specification; I followed it and
788 changed what the client sends and it appears to be working now.

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

PH
806PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
807 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
808 they consult the DNS. I had assumed they would set it the way they
809 wanted; and indeed my experiments on Linux seem to show that in some
810 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
811 To be on the safe side, however, I have now made the interface to
812 host_find_byname() similar to host_find_bydns(), with an argument
813 containing the DNS resolver options. The host_find_byname() function now
814 sets these options at its start, just as host_find_bydns() does. The smtp
815 transport options dns_qualify_single and dns_search_parents are passed to
816 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
817 of host_find_byname() use the default settings of RES_DEFNAMES
818 (qualify_single) but not RES_DNSRCH (search_parents).

820PH/17 Applied (a modified version of) Nico Erfurth's patch to make
821 spool_read_header() do less string testing, by means of a preliminary
822 switch on the second character of optional "-foo" lines. (This is
823 overdue, caused by the large number of possibilities that now exist.
824 Originally there were few.) While I was there, I also converted the
825 str(n)cmp tests so they don't re-test the leading "-" and the first
826 character, in the hope this might squeeze out yet more improvement.

828PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
829 flag allowing group syntax was set by the header_syntax check but not
830 turned off, possible causing trouble later; (2) The flag was not being
831 set at all for the header_verify test, causing "group"-style headers to
832 be rejected. I have now set it in this case, and also caused header_
833 verify to ignore an empty address taken from a group. While doing this, I
834 came across some other cases where the code for allowing group syntax
835 while scanning a header line wasn't quite right (mostly, not resetting
836 the flag correctly in the right place). These bugs could have caused
837 trouble for malformed header lines. I hope it is now all correct.

839PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
840 with the "reply" argument non-NULL. The code, however (which originally

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

PH
845PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
846 feature that was used to support insecure browsers during the U.S. crypto
847 embargo. It requires special client support, and Exim is probably the
848 only MTA that supported it -- and would never use it because real RSA is
849 always available. This code has been removed, because it had the bad
850 effect of slowing Exim down by computing (never used) parameters for the
851 RSA_EXPORT functionality.

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

891PH/30 Exim was sometimes attempting to deliver messages that had suffered
892 address errors (4xx response to RCPT) over the same connection as other
893 messages routed to the same hosts. Such deliveries are always "forced",
894 so retry times are not inspected. This resulted in far too many retries
895 for the affected addresses. The effect occurred only when there were more
896 hosts than the hosts_max_try setting in the smtp transport when it had
897 the 4xx errors. Those hosts that it had tried were not added to the list
898 of hosts for which the message was waiting, so if all were tried, there
899 was no problem. Two fixes have been applied:
900
901 (i) If there are any address or message errors in an SMTP delivery, none
902 of the hosts (tried or untried) are now added to the list of hosts
903 for which the message is waiting, so the message should not be a
904 candidate for sending over the same connection that was used for a
905 successful delivery of some other message. This seems entirely
906 reasonable: after all the message is NOT "waiting for some host".
907 This is so "obvious" that I'm not sure why it wasn't done
908 previously. Hope I haven't missed anything, but it can't do any
909 harm, as the worst effect is to miss an optimization.
910
911 (ii) If, despite (i), such a delivery is accidentally attempted, the
912 routing retry time is respected, so at least it doesn't keep
913 hammering the server.

928PH/35 The error "getsockname() failed: connection reset by peer" was being
929 written to the panic log as well as the main log, but it isn't really

931 removed the panic log writing for the ECONNRESET error when getsockname()
932 fails.
933
48c7f9e2
PH
934PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
935 runs only) independently of the message's sender address. This meant
936 that, if the 4xx error was in fact related to the sender, a different
937 message to the same recipient with a different sender could confuse
938 things. In particualar, this can happen when sending to a greylisting
939 server, but other circumstances could also provoke similar problems.
940 I have changed the default so that the retry time for these errors is now
941 based a combination of the sender and recipient addresses. This change
942 can be overridden by setting address_retry_include_sender=false in the
943 smtp transport.

1211PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
1212 "Deny" causes Exim to reject the incoming connection with a 554 error.
1213 Unfortunately, if there is a major crisis, such as a disk failure,
1214 tcp-wrappers gives "deny", whereas what one would like would be some
1215 kind of temporary error. A kludge has been added to help with this.
1216 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1217 554 error is used if errno is still zero or contains ENOENT (which occurs
1218 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1219 451 error is used.

1241PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

1243 up the contents of the maildirsize file. This was because the regex was
1244 used only to exclude .Trash (or whatever) when the size of the mailbox
1245 was calculated. There was no check that a delivery was happening into an
1246 excluded directory. This bug has been fixed by ignoring all quota

1253-----------------
1254
1255PH/01 The code for finding all the local interface addresses on a FreeBSD
1256 system running IPv6 was broken. This may well have applied to all BSD
1257 systems, as well as to others that have similar system calls. The broken
1258 code found IPv4 interfaces correctly, but gave incorrect values for the
1259 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1260 that it would not match correctly against @[] and not recognize the IPv6
1261 addresses as local.

1302 syntactically invalid From: or Reply-to: line, and a filter used this to
1303 generate an autoreply, and therefore failed to obtain an address for the
1304 autoreply, Exim could try to deliver to a non-existent relative file
1305 name, causing unrelated and misleading errors. What now happens is that
1306 it logs this as a hard delivery error, but does not attempt to create a

1324 non-existent - all you got was a failure to exec. I have made two
1325 changes:
1326
1327 (a) Failures to set uid/gid, the current directory, or a process leader
1328 in a subprocess such as that created by queryprogram now generate
1329 suitable debugging ouput when -d is set.
1330

1333 the subprocess without attempting to change uid/gid.

1338PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1339 additional section of a DNS packet that returns MX or SRV records.
1340 Instead, it always explicitly searches for A/AAAA records. This avoids
1341 major problems that occur when a DNS server includes only records of one
1342 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1343 fixed another bug: if SRV records were looked up and the corresponding
1344 address records were *not* found in the additional section, the port
1345 values from the SRV records were lost.

1347PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
1355PH/19 When calculating a retry time, Exim used to measure the "time since
1356 failure" by looking at the "first failed" field in the retry record. Now
1357 it does not use this if it is later than than the arrival time of the
1358 message. Instead it uses the arrival time. This makes for better
1359 behaviour in cases where some deliveries succeed, thus re-setting the
1360 "first failed" field. An example is a quota failure for a huge message
1361 when small messages continue to be delivered. Without this change, the
1362 "time since failure" will always be short, possible causing more frequent
1363 delivery attempts for the huge message than are intended.

PH
1460PH/42 The content-scanning code uses fopen() to create files in which to put
1461 message data. Previously it was not paying any attention to the mode of
1462 the files. Exim runs with umask(0) because the rest of the code creates
1463 files with open(), and sets the required mode explicitly. Thus, these
1464 files were ending up world-writeable. This was not a big issue, because,
1465 being within the spool directory, they were not world-accessible. I have
1466 created a function called modefopen, which takes an additional mode
1467 argument. It sets umask(777), creates the file, chmods it to the required
1468 mode, then resets the umask. All the relevant calls to fopen() in the
1469 content scanning code have been changed to use this function.

1506
1507 (i) Exim was not creating retry information for temporary errors given
1508 for individual recipients after the DATA command when the smtp transport
1509 was used in LMTP mode. This meant that they could be retried too
1510 frequently, and not timed out correctly.
1511
1512 (ii) Exim was setting the flag that allows error details to be returned
1513 for LMTP errors on RCPT commands, but not for LMTP errors for individual
1514 recipients that were returned after the DATA command.
1515
1516PH/53 This is related to PH/52, but is more general: for any failing address,
1517 when detailed error information was permitted to be returned to the

1576PH/68 The bounce_return_message and bounce_return_body options were not being
1577 honoured for bounces generated during the reception of non-SMTP messages.
1578 In particular, this applied to messages rejected by the ACL. This bug has
1579 been fixed. However, if bounce_return_message is true and bounce_return_
1580 body is false, the headers that are returned for a non-SMTP message
1581 include only those that have been read before the error was detected.
1582 (In the case of an ACL rejection, they have all been read.)

1590PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
1591 function verify_get_ident() calls ip_connect() to connect a socket, but
1592 if the "connect()" function timed out, ip_connect() used to close the
1593 socket. However, verify_get_ident() also closes the socket later, and in
1594 between Exim writes to the log, which may get opened at this point. When
1595 the socket was closed in ip_connect(), the log could get the same file
1596 descriptor number as the socket. This naturally causes chaos. The fix is
1597 not to close the socket in ip_connect(); the socket should be closed by
1598 the function that creates it. There was only one place in the code where
1599 this was missing, in the iplookup router, which I don't think anybody now
1600 uses, but I've fixed it anyway.

1619PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
1620
1621 (1) Generate an error if the third argument for the ${prvs expansion is
1622 not a single digit.
1623
1624 (2) Treat a missing third argument of ${prvscheck as if it were an empty
1625 string.
1626
1627 (3) Reset the variables that are obtained from the first argument of
1628 ${prvscheck and used in the second argument before leaving the code,
1629 because their memory is reclaimed, so using them afterwards may do
1630 silly things.
1631
1632 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
1633 one (it's much easier than Tom thought :-).
1634
1635 (5) Because of (4), we can now allow for the use of $prvscheck_result
1636 inside the third argument.

1651 may be more than one such address. If so, they are comma-separated, like

1656PH/06 When a client host used a correct literal IP address in a HELO or EHLO
1657 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
1658 not being looked up in the rDNS to get a host name, Exim was showing the
1659 IP address twice in Received: lines, even though the IP addresses were
1660 identical. For example:
1661
1662 Received: from [1.2.3.4] (helo=[1.2.3.4])
1663
1664 However, if the real host name was known, it was omitting the HELO data
1665 if it matched the actual IP address. This has been tidied up so that it
1666 doesn't show the same IP address twice.

1692PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

1694
1695 Auto-submitted: auto-generated
1696
1697 in the messages that it generates (bounce messages and others, such as
1698 warnings). In the case of bounce messages for non-SMTP mesages, there was
1699 also a typo: it was using "Auto_submitted" (underscore instead of
1700 hyphen). Since every message generated by Exim is necessarily in response
1701 to another message, thes have all been changed to:
1702
1703 Auto-Submitted: auto-replied
1704
1705 in accordance with these statements in the RFC:
1706
1707 The auto-replied keyword:
1708
1709 - SHOULD be used on messages sent in direct response to another
1710 message by an automatic process,
1711
1712 - MUST NOT be used on manually-generated messages,

1715 Disposition Notifications (MDNs),

1755PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
1756 canonical form (as documented). However, after a host name lookup from
1757 the IP address, check_host() was doing a simple string comparison with
1758 addresses acquired from the DNS when checking that the found name did
1759 have the original IP as one of its addresses. Since any found IPv6
1760 addresses are likely to be in abbreviated form, the comparison could
1761 fail. Luckily, there already exists a function for doing the comparison
1762 by converting both addresses to binary, so now that is used instead of
1763 the text comparison.

2060PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2061 with the definition in sysexits.h (which is #included earlier).
2062 Fortunately, Exim does not actually use EX_OK. The code used to try to
2063 preserve the sysexits.h value, by assumimg that macro definitions were
2064 scanned for macro replacements. I have been disabused of this notion,
2065 so now the code just undefines EX_OK before #including unistd.h.

2067PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout

2070 This seems wrong - if the receiver was accepting one byte at a time it
2071 would take for ever. The timeout is now adjusted when this happens. It
2072 doesn't have to be particularly precise.

2148 case the guess is not the same as the compiled default, so the script
2149 suddenly stopped working when I started to use syslog. The patch checks
2150 to see if log_file_path is "". If so, it attempts to read it from exim

2280
2281PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2282 that changes the way the GnuTLS parameters are stored in the cache file.
2283 The new format can be generated externally. For backward compatibility,
2284 if the data in the cache doesn't make sense, Exim assumes it has read an
2285 old-format file, and it generates new data and writes a new file. This
2286 means that you can't go back to an older release without removing the
2287 file.
2288
2289PH/03 A redirect router that has both "unseen" and "one_time" set does not
2290 work if there are any delivery delays because "one_time" forces the
2291 parent to be marked "delivered", so its unseen clone is never tried
2292 again. For this reason, Exim now forbids the simultaneous setting of
2293 these two options.
2294
2295PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2296 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2297 entry if you want to know the details. The fix, however, neglected to
2298 consider the case when local delivery batching is involved. The test for
2299 "previously delivered" was not happening when checking to see if an
2300 address could be batched with a previous (undelivered) one; under
2301 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2302 address.

PH
2303
2304PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2307PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2308 header_syntax) but Exim was just ignoring anything given after a slash.
2309 In particular, this caused confusion with an attempt to use "verify =
2310 reverse_host_lookup/defer_ok". An error is now given when options are
2311 supplied for verify items that do not have them. (Maybe reverse_host_
2312 lookup should have a defer_ok option, but that's a different point.)
2313
2314PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2367 the file with the wrong ownership). There was no test for failure of this
2368 fork() call, which would lead to the process getting stuck as it waited

2378 (an event I could not check), uninitialized data bytes were printed.

2380 "input=".

PH
2390PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2391 hadn't been configured. The fix is from Juergen Kreileder, who
2392 understands it better than I do:
2393
2394 "Here's what I see happening with three configured cyrus_sasl
2395 authenticators configured (plain, login, cram-md5):
2396
2397 On startup auth_cyrus_sasl_init() gets called for each of these.
2398 This means three calls to sasl_listmech() without a specified mech_list.
2399 => SASL tests which mechs of all available mechs actually work
2400 => three warnings about OTP not working
2401 => the returned list contains: plain, login, cram-md5, digest-md5, ...
2402
2403 With the patch, sasl_listmech() also gets called three times. But now
2404 SASL's mech_list option is set to the server_mech specified in the the
2405 authenticator. Or in other words, the answer from sasl_listmech()
2406 gets limited to just the mech you're testing for (which is different
2407 for each call.)
2408 => the return list contains just 'plain' or 'login', 'cram-md5' or
2409 nothing depending on the value of ob->server_mech.
2410
2411 I've just tested the patch: Authentication still works fine,
2412 unavailable mechs specified in the exim configuration are still
2413 caught, and the auth.log warnings about OTP are gone."

PH
2477PH/37 Exim used to check for duplicate addresses in the middle of routing, on
2478 the grounds that routing the same address twice would always produce the
2479 same answer. This might have been true once, but it is certainly no
2480 longer true now. Routing a child address may depend on the previous
2481 routing that produced that child. Some complicated redirection strategies
2482 went wrong when messages had multiple recipients, and made Exim's
2483 behaviour dependent on the order in which the addresses were given.
2484
2485 I have moved the duplicate checking until after the routing is complete.
2486 Exim scans the addresses that are assigned to local and remote
2487 transports, and removes any duplicates. This means that more work will be
2488 done, as duplicates will always all be routed, but duplicates are
2489 presumably rare, so I don't expect this is of any significance.
2490
2491 For deliveries to pipes, files, and autoreplies, the duplicate checking
2492 still happens during the routing process, since they are not going to be
2493 routed further.

2538 consistency with the overall process timeout, these timeouts are now
2539 treated as errors, giving rise to delivery failures by default. However,
2540 there is now a new Boolean option for the pipe transport called
2541 timeout_defer, which, if set TRUE, converts the failures into defers for
2542 both kinds of timeout. A transport filter timeout is now identified in

2552A note about Exim versions 4.44 and 4.50
2553----------------------------------------
2554
2555Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
2556changes of various kinds. As a consequence, a big documentation update was
2557needed. This delayed the release for rather longer than seemed good, especially
2558in the light of a couple of (minor) security issues. Therefore, the changes
2559that fixed bugs were backported into 4.43, to create a 4.44 maintenance
2560release. So 4.44 and 4.50 are in effect two different branches that both start
2561from 4.43.
2562
2563I have left the 4.50 change log unchanged; it contains all the changes since
25644.43. The change log for 4.44 is below; many of its items are identical to
2565those for 4.50. This seems to be the most sensible way to preserve the
2566historical information.

2584 5. There are several places where Exim runs a non-Exim command in a
2585 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2586 was being done only for the command run by the queryprogram router. It is
2587 now done for all such subprocesses. The other cases are: ${run, transport
2588 filters, and the commands run by the lmtp and pipe transports.

2593 descriptors. Exim was using setrlimit() to set 1000 as a large value
2594 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2595 systems. I've change it so that if it can't get 1000, it tries for 256.

2643 ignore_target_hosts.
2644
264523. When checking ignore_target_hosts for an ipliteral router, no host name was
2646 being passed; this would have caused $sender_host_name to have been used if
2647 matching the list had actually called for a host name (not very likely,
2648 since this list is usually IP addresses). A host name is now passed as
2649 "[x.x.x.x]".
2650

PH
265124. Changed the calls that set up the SIGCHLD handler in the daemon to use the
2652 code that specifies a non-restarting handler (typically sigaction() in
2653 modern systems) in an attempt to fix a rare and obscure crash bug.
2654
265525. Narrowed the window for a race in the daemon that could cause it to ignore
2656 SIGCHLD signals. This is not a major problem, because they are used only to
2657 wake it up if nothing else does.

PH
266929. In an address list, if the pattern was not a regular expression, an empty
2670 subject address (from a bounce message) matched only if the pattern was an
2671 empty string. Non-empty patterns were not even tested. This was the wrong
2672 because it is perfectly reasonable to use an empty address as part of a
2673 database query. An empty address is now tested by patterns that are
2674 lookups. However, all the other forms of pattern expect the subject to
2675 contain a local part and a domain, and therefore, for them, an empty
2676 address still always fails if the pattern is not itself empty.
2677

PH
267830. Exim went into a mad DNS loop when attempting to do a callout where the
2679 host was specified on an smtp transport, and looking it up yielded more

PH
268231. Re-factored the code for checking spool and log partition space into a
2683 function that finds that data and another that does the check. The former

2685 $spool_inodes, and $log_inodes.
2686

PH
268732. The RFC2047 encoding function was originally intended for short strings
2688 such as real names; it was not keeping to the 75-character limit for
2689 encoded words that the RFC imposes. It now respects the limit, and
2690 generates multiple encoded words if necessary. To be on the safe side, I
2691 have increased the buffer size for the ${rfc2047: expansion operator from
2692 1024 to 2048 bytes.
2693
063b1e99
PH
269433. It is now permitted to omit both strings after an "if" condition; if the
2695 condition is true, the result is "true". As before, when the second string
2696 is omitted, a false condition yields an empty string. This makes it less
2697 cumbersome to write custom ACL and router conditions.
2698
652e1b65
PH
269934. Failure to deliver a bounce message always caused it to be frozen, even if
2700 there was an errors_to setting on the router. The errors_to setting is now
2701 respected.

PH
270736. The table in the code that translates DNS record types into text (T_A to
2708 "A" for instance) was missing entries for NS and CNAME. It is just possible
2709 that this could have caused confusion if both these types were looked up
2710 for the same domain, because the text type is used as part of Exim's
2711 per-process caching. But the chance of anyone hitting this buglet seems
2712 very small.

PH
271437. The dnsdb lookup has been extended in a number of ways.

277652. Exim crashed if a remote delivery caused a very long error message to be
2777 recorded - for instance if somebody sent an entire SpamAssassin report back
2778 as a large number of 550 error lines. This bug was coincidentally fixed by
2779 increasing the size of one of Exim's internal buffers (big_buffer) that
2780 happened as part of the Exiscan merge. However, to be on the safe side, I
2781 have made the code more robust (and fixed the comments that describe what
2782 is going on).
2783

PH
278453. Now that there can be additional text after "Completed" in log lines (if
2785 the queue_time_overall log selector is set), a one-byte patch to exigrep
2786 was needed to allow it to recognize "Completed" as not the last thing in
2787 the line.

PH
278954. The LDAP lookup was not handling a return of LDAP_RES_SEARCH_REFERENCE. A
2790 patch that reportedly fixes this has been added. I am not expert enough to
2791 create a test for it. This is what the patch creator wrote:
2792
2793 "I found a little strange behaviour of ldap code when working with
2794 Windows 2003 AD Domain, where users was placed in more than one
2795 Organization Units. When I tried to give exim partial DN, the exit code
2796 of ldap_search was unknown to exim because of LDAP_RES_SEARCH_REFERENCE.
2797 But simultaneously result of request was absolutely normal ldap result,
2798 so I produce this patch..."
2799
3295e65b
PH
2800 Later: it seems that not all versions of LDAP support LDAP_RES_SEARCH_
2801 REFERENCE, so I have modified the code to exclude the patch when that macro
2802 is not defined.
2803

PH
280455. Some experimental protocols are using DNS PTR records for new purposes. The
2805 keys for these records are domain names, not reversed IP addresses. The
b975ba52
PH
2806 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
2807 leaves it alone. Component reversal etc. now happens only for IP addresses.

PH
281558. The exicyclog utility now does better if the number of log files to keep

PH
281859. Two changes related to the smtp_active_hostname option:
2819
2820 (1) $smtp_active_hostname is now available as a variable.
2821 (2) The default for smtp_banner uses $smtp_active_hostname instead
2822 of $primary_hostname.
2823
b975ba52
PH
282460. The host_aton() function is supposed to be passed a string that is known
2825 to be a valid IP address. However, in the case of IPv6 addresses, it was
2826 not checking this. This is a hostage to fortune. Exim now panics and dies
2827 if the condition is not met. A case was found where this could be provoked
85b87bc2
PH
2828 from a dnsdb PTR lookup with an IPv6 address that had more than 8
2829 components; fortuitously, this particular loophole had already been fixed
2830 by change 4.50/55 above.
2831
2832 If there are any other similar loopholes, the new check in host_aton()
2833 itself should stop them being exploited. The report I received stated that
2834 data on the command line could provoke the exploit when Exim was running as
2835 exim, but did not say which command line option was involved. All I could
2836 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is
2837 running as the user.

PH
284863. The daemon start-up calls getloadavg() while still root for those OS that
2849 need the first call to be done as root, but it missed one case: when
2850 deliver_queue_load_max is set with deliver_drop_privilege. This is
2851 necessary for the benefit of the queue runner, because there is no re-exec
2852 when deliver_drop_privilege is set.

2855 This has been fixed.
2856
60dc5e56
PH
285765. Caching of lookup data for "hosts =" ACL conditions, when a named host list
2858 was in use, was not putting the data itself into the right store pool;
2859 consequently, it could be overwritten for a subsequent message in the same
2860 SMTP connection. (Fix 4.40/11 dealt with the non-cache case, but overlooked
2861 the caching.)

PH
286567. The string_is_ip_address() function returns 0, 4, or 6, for "no an IP
2866 address", "IPv4 address", and "IPv6 address", respectively. Some calls of
2867 the function were treating the return as a boolean value, which happened to
2868 work because 0=false and not-0=true, but is not correct code.
2869

PH
287068. The host_aton() function was not handling scoped IPv6 addresses (those
2871 with, for example, "%eth0" on the end) correctly.

PH
287369. Fixed some compiler warnings in acl.c for the bitmaps specified with

2875 apparently mutter when there is no cast.
2876

PH
287770. If an address verification called from an ACL failed, and did not produce a
2878 user-specific message (i.e. there was only a "system" message), nothing was
2879 put in $acl_verify_message. In this situation, it now puts the system
2880 message there.

00f00ca5
PH
288271. Change 4.23/11 added synchronization checking at the start of an SMTP
2883 session; change 4.31/43 added the unwanted input to the log line - except
2884 that it did not do this in the start of session case. It now does.
2885
c9bdd01c
PH
288672. After a timeout in a callout SMTP session, Exim still sent a QUIT command.
2887 This is wrong and can cause the other end to generate a synchronization
2888 error if it is another Exim or anything else that does the synchronization
2889 check. A QUIT command is no longer sent after a timeout.

2897 verify = header_sender/callout=defer_ok
2898
76a2d7ba
PH
289975. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
2900 those file descriptors could be used for SMTP connections. If anything
2901 wrote to stderr (the example that came up was "warn" in embedded Perl), it
2902 could be sent to the SMTP client, causing chaos. The daemon now opens
2903 stdin, stdout, and stderr to /dev/null when it puts itself into the
2904 background.
2905
290676. Arrange for output from Perl's "warn" command to be written to Exim's main
2907 log by default. The user can override this with suitable Perl magic.
2908
04f7d5b9
PH
290977. The use of log_message on a "discard" ACL verb, which is supposed to add to
2910 the log message when discard triggers, was not working for the DATA ACL or
2911 for the non-SMTP ACL.

PH
291378. Error message wording change in sieve.c.
2914
bb6e88ff
PH
291579. If smtp_accept_max_per_host was set, the number of connections could be
2916 restricted to fewer than expected, because the daemon was trying to set up
2917 a new connection before checking whether the processes handling previous
2918 connections had finished. The check for completed processes is now done
2919 earlier. On busy systems, this bug wouldn't be noticed because something
2920 else would have woken the daemon, and it would have reaped the completed
2921 process earlier.
2922
1e70f85b
PH
292380. If a message was submitted locally by a user whose login name contained one
2924 or more spaces (ugh!), the spool file that Exim wrote was not re-readable.
2925 It caused a spool format error. I have fixed the spool reading code. A
2926 related problem was that the "from" clause in the Received: line became
2927 illegal because of the space(s). It is now covered by ${quote_local_part.

2943----------------------------------------------------
2944See the note above about the 4.44 and 4.50 releases.
2945----------------------------------------------------
2946
2947
2948Exim version 4.44
2949-----------------
2950
2951 1. Change 4.43/35 introduced a bug that caused file counts to be
2952 incorrectly computed when quota_filecount was set in an appendfile
2953 transport
2954
2955 2. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
2956 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
2957 place.
2958
2959 3. Give more explanation in the error message when the command for a transport
2960 filter fails to execute.
2961
2962 4. There are several places where Exim runs a non-Exim command in a
2963 subprocess. The SIGUSR1 signal should be disabled for these processes. This
2964 was being done only for the command run by the queryprogram router. It is
2965 now done for all such subprocesses. The other cases are: ${run, transport
2966 filters, and the commands run by the lmtp and pipe transports.
2967
2968 5. Some older OS have a limit of 256 on the maximum number of file
2969 descriptors. Exim was using setrlimit() to set 1000 as a large value
2970 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
2971 systems. I've change it so that if it can't get 1000, it tries for 256.
2972
2973 6. "control=submission" was allowed, but had no effect, in a DATA ACL. This
2974 was an oversight, and furthermore, ever since the addition of extra
2975 controls (e.g. 4.43/32), the checks on when to allow different forms of
2976 "control" were broken. There should now be diagnostics for all cases when a
2977 control that does not make sense is encountered.
2978
2979 7. $recipients is now available in the predata ACL (oversight).
2980
2981 8. Tidy the search cache before the fork to do a delivery from a message
2982 received from the command line. Otherwise the child will trigger a lookup
2983 failure and thereby defer the delivery if it tries to use (for example) a
2984 cached ldap connection that the parent has called unbind on.
2985
2986 9. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
2987 of $address_data from the recipient verification was clobbered by the
2988 sender verification.
2989
299010. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
2991 was its contents. (It was OK if the option was not defined at all.)
2992
299311. A "Completed" log line is now written for messages that are removed from
2994 the spool by the -Mrm option.
2995
299612. $host_address is now set to the target address during the checking of
2997 ignore_target_hosts.
2998
299913. When checking ignore_target_hosts for an ipliteral router, no host name was
3000 being passed; this would have caused $sender_host_name to have been used if
3001 matching the list had actually called for a host name (not very likely,
3002 since this list is usually IP addresses). A host name is now passed as
3003 "[x.x.x.x]".
3004
300514. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3006 code that specifies a non-restarting handler (typically sigaction() in
3007 modern systems) in an attempt to fix a rare and obscure crash bug.
3008
300915. Narrowed the window for a race in the daemon that could cause it to ignore
3010 SIGCHLD signals. This is not a major problem, because they are used only to
3011 wake it up if nothing else does.
3012
301316. A malformed maildirsize file could cause Exim to calculate negative values
3014 for the mailbox size or file count. Odd effects could occur as a result.
3015 The maildirsize information is now recalculated if the size or filecount
3016 end up negative.
3017
301817. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3019 support for a long time. Removed HAVE_SYS_VFS_H.
3020
ea3a6f44 302118. Updated exipick to current release from John Jetmore.
bbe902f0
PH
3022
302319. Allow an empty sender to be matched against a lookup in an address list.
3024 Previously the only cases considered were a regular expression, or an
3025 empty pattern.
3026
302720. Exim went into a mad DNS lookup loop when doing a callout where the
3028 host was specified on the transport, if the DNS lookup yielded more than
3029 one IP address.
3030
ea3a6f44
NM
303121. The RFC2047 encoding function was originally intended for short strings
3032 such as real names; it was not keeping to the 75-character limit for
3033 encoded words that the RFC imposes. It now respects the limit, and
3034 generates multiple encoded words if necessary. To be on the safe side, I
3035 have increased the buffer size for the ${rfc2047: expansion operator from
3036 1024 to 2048 bytes.
bbe902f0 3037
ea3a6f44
NM
303822. Failure to deliver a bounce message always caused it to be frozen, even if
3039 there was an errors_to setting on the router. The errors_to setting is now
3040 respected.
bbe902f0
PH
3041
304223. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3043 canonical form (fully expanded) before being placed in
3044 $sender_host_address.
3045
304624. Updated eximstats to version 1.33
3047
ea3a6f44
NM
304825. Include certificate and key file names in error message when GnuTLS fails
3049 to set them up, because the GnuTLS error message doesn't include the name
3050 of the failing file when there is a problem reading it.
bbe902f0
PH
3051
305226. Expand error message when OpenSSL has problems setting up cert/key files.
ea3a6f44 3053 As per change 25.
bbe902f0 3054
ea3a6f44
NM
305527. Reset the locale to "C" after calling embedded Perl, in case it was changed
3056 (this can affect the format of dates).
bbe902f0 3057
ea3a6f44
NM
305828. exim_tidydb, when checking for the continued existence of a message for
3059 which it has found a message-specific retry record, was not finding
3060 messages that were in split spool directories. Consequently, it was
3061 deleting retry records that should have stayed in existence.
bbe902f0
PH
3062
306329. eximstats updated to version 1.35
3064 1.34 - allow eximstats to parse syslog lines as well as mainlog lines
3065 1.35 - bugfix such that pie charts by volume are generated correctly

306730. The SPA authentication driver was not abandoning authentication and moving
3068 on to the next authenticator when an expansion was forced to fail,
3069 contradicting the general specification for all authenticators. Instead it
3070 was generating a temporary error. It now behaves as specified.
bbe902f0 3071
ea3a6f44
NM
307231. The default ordering of permitted cipher suites for GnuTLS was pessimal
3073 (the order specifies the preference for clients). The order is now AES256,
3074 AES128, 3DES, ARCFOUR128.
bbe902f0 3075

308733. Some experimental protocols are using DNS PTR records for new purposes. The
3088 keys for these records are domain names, not reversed IP addresses. The
3089 dnsdb PTR lookup now tests whether its key is an IP address. If not, it
3090 leaves it alone. Component reversal etc. now happens only for IP addresses.

309334. The host_aton() function is supposed to be passed a string that is known
3094 to be a valid IP address. However, in the case of IPv6 addresses, it was
3095 not checking this. This is a hostage to fortune. Exim now panics and dies

3099 by change 4.50/55 or 4.44/33 above.
3100
3101 If there are any other similar loopholes, the new check in host_aton()
3102 itself should stop them being exploited. The report I received stated that
3103 data on the command line could provoke the exploit when Exim was running as
3104 exim, but did not say which command line option was involved. All I could
3105 find was the use of -be with a bad dnsdb PTR lookup, and in that case it is

3128 < 0 before doing a fflush(). This bug looks as though it goes back to the
3129 introduction of TLS in release 3.20, but "sometimes" must have been rare

3133Exim version 4.43
3134-----------------
3135
3136 1. Fixed a longstanding but relatively impotent bug: a long time ago, before
3137 PIPELINING, the function smtp_write_command() used to return TRUE or FALSE.
3138 Now it returns an integer. A number of calls were still expecting a T/F
3139 return. Fortuitously, in all cases, the tests worked in OK situations,
3140 which is the norm. However, things would have gone wrong on any write
3141 failures on the smtp file descriptor. This function is used when sending
3142 messages over SMTP and also when doing verify callouts.
3143
3144 2. When Exim is called to do synchronous delivery of a locally submitted
3145 message (the -odf or -odi options), it no longer closes stderr before doing
3146 the delivery.
3147
3148 3. Implemented the mua_wrapper option.
3149
3150 4. Implemented mx_fail_domains and srv_fail_domains for the dnslookup router.
3151
3152 5. Implemented the functions header_remove(), header_testname(),
3153 header_add_at_position(), and receive_remove_recipient(), and exported them
3154 to local_scan().
3155
3156 6. If an ACL "warn" statement specified the addition of headers, Exim already
3157 inserted X-ACL-Warn: at the start if there was no header name. However, it
3158 was not making this test for the second and subsequent header lines if
3159 there were newlines in the string. This meant that an invalid header could
3160 be inserted if Exim was badly configured.
3161
3162 7. Allow an ACL "warn" statement to add header lines at the start or after all
3163 the Received: headers, as well as at the end.
3164
3165 8. Added the rcpt_4xx retry error code.
3166
3167 9. Added postmaster_mailfrom=xxx to callout verification option.
3168
316910. Added mailfrom=xxxx to the callout verification option, for verify=
3170 header_sender only.
3171
317211. ${substr_1_:xxxx} and ${substr__3:xxxx} are now diagnosed as syntax errors
3173 (they previously behaved as ${substr_1_0:xxxx} and ${substr:_0_3:xxxx}).
3174
317512. Inserted some casts to stop certain compilers warning when using pointer
3176 differences as field lengths or precisions in printf-type calls (mostly
3177 affecting debugging statements).
3178
317913. Added optional readline() support for -be (dynamically loaded).
3180
318114. Obscure bug fix: if a message error (e.g. 4xx to MAIL) happened within the
3182 same clock tick as a message's arrival, so that its received time was the
3183 same as the "first fail" time on the retry record, and that message
3184 remained on the queue past the ultimate address timeout, every queue runner
3185 would try a delivery (because it was past the ultimate address timeout) but
3186 after another failure, the ultimate address timeout, which should have then
3187 bounced the address, did not kick in. This was a "< instead of <=" error;
3188 in most cases the first failure would have been in the next clock tick
3189 after the received time, and all would be well.
3190
319115. The special items beginning with @ in domain lists (e.g. @mx_any) were not
3192 being recognized when the domain list was tested by the match_domain
3193 condition in an expansion string.
3194
319516. Added the ${str2b64: operator.
3196
319717. Exim was always calling setrlimit() to set a large limit for the number of
3198 processes, without checking whether the existing limit was already
3199 adequate. (It did check for the limit on file descriptors.) Furthermore,
3200 errors from getrlimit() and setrlimit() were being ignored. Now they are
3201 logged to the main and panic logs, but Exim does carry on, to try to do its
3202 job under whatever limits there are.
3203
320418. Imported PCRE 5.0.
3205
320619. Trivial typo in log message " temporarily refused connection" (the leading
3207 space).
3208
320920. If the log selector return_path_on_delivery was set and an address was
3210 redirected to /dev/null, the delivery process crashed because it assumed
3211 that a return path would always be set for a "successful" delivery. In this
3212 case, the whole delivery is bypassed as an optimization, and therefore no
3213 return path is set.
3214
321521. Internal re-arrangement: the function for sending a challenge and reading
3216 a response while authentication was assuming a zero-terminated challenge
3217 string. It's now changed to take a pointer and a length, to allow for
3218 binary data in such strings.
3219
322022. Added the cyrus_sasl authenticator (code supplied by MBM).
3221
322223. Exim was not respecting finduser_retries when seeking the login of the
3223 uid under which it was called; it was always trying 10 times. (The default
3224 setting of finduser_retries is zero.) Also, it was sleeping after the final
3225 failure, which is pointless.
3226
322724. Implemented tls_on_connect_ports.
3228
322925. Implemented acl_smtp_predata.
3230
323126. If the domain in control=submission is set empty, Exim assumes that the
3232 authenticated id is a complete email address when it generates From: or
3233 Sender: header lines.
3234
323527. Added "#define SOCKLEN_T int" to OS/os.h-SCO and OS/os.h-SCO_SV. Also added
3236 definitions to OS/Makefile-SCO and OS/Makefile-SCO_SV that put basename,
3237 chown and chgrp in /bin and hostname in /usr/bin.
3238
323928. Exim was keeping the "process log" file open after each use, just as it
3240 does for the main log. This opens the possibility of it remaining open for
3241 long periods when the USR1 signal hits a daemon. Occasional processlog
3242 errors were reported, that could have been caused by this. Anyway, it seems
3243 much more sensible not to leave this file open at all, so that is what now
3244 happens.
3245
324629. The long-running daemon process does not normally write to the log once it
3247 has entered its main loop, and it closes the log before doing so. This is
3248 so that log files can straightforwardly be renamed and moved. However,
3249 there are a couple of unusual error situations where the daemon does write
3250 log entries, and I had neglected to close the log afterwards.
3251
325230. The text of an SMTP error response that was received during a remote
3253 delivery was being truncated at 512 bytes. This is too short for some of
3254 the long messages that one sometimes sees. I've increased the limit to
3255 1024.
3256
325731. It is now possible to make retry rules that apply only when a message has a
3258 specific sender, in particular, an empty sender.
3259
326032. Added "control = enforce_sync" and "control = no_enforce_sync". This makes
3261 it possible to be selective about when SMTP synchronization is enforced.
3262
326333. Added "control = caseful_local_part" and "control = "caselower_local_part".
3264
326532. Implemented hosts_connection_nolog.
3266
326733. Added an ACL for QUIT.
3268
326934. Setting "delay_warning=" to disable warnings was not working; it gave a
3270 syntax error.
3271
327235. Added mailbox_size and mailbox_filecount to appendfile.
3273
327436. Added control = no_multiline_responses to ACLs.
3275
327637. There was a bug in the logic of the code that waits for the clock to tick
3277 in the case where the clock went backwards by a substantial amount such
3278 that the microsecond fraction of "now" was more than the microsecond
3279 fraction of "then" (but the whole seconds number was less).
3280
328138. Added support for the libradius Radius client library this is found on
3282 FreeBSD (previously only the radiusclient library was supported).
3283
3284
3285Exim version 4.42
3286-----------------
3287
3288 1. When certain lookups returned multiple values in the form name=value, the
3289 quoting of the values was not always being done properly. Specifically:
3290 (a) If the value started with a double quote, but contained no whitespace,
3291 it was not quoted.
3292 (b) If the value contained whitespace other than a space character (i.e.
3293 tabs or newlines or carriage returns) it was not quoted.
3294 This fix has been applied to the mysql and pgsql lookups by writing a
3295 separate quoting function and calling it from the lookup code. The fix
3296 should probably also be applied to nisplus, ibase and oracle lookups, but
3297 since I cannot test any of those, I have not disturbed their existing code.
3298
3299 2. A hit in the callout cache for a specific address caused a log line with no
3300 reason for rejecting RCPT. Now it says "Previous (cached) callout
3301 verification failure".
3302
3303 3. There was an off-by-one bug in the queryprogram router. An over-long
3304 return line was truncated at 256 instead of 255 characters, thereby
3305 overflowing its buffer with the terminating zero. As well as fixing this, I
3306 have increased the buffer size to 1024 (and made a note to document this).
3307
3308 4. If an interrupt, such as the USR1 signal that is send by exiwhat, arrives
3309 when Exim is waiting for an SMTP response from a remote server, Exim
3310 restarts its select() call on the socket, thereby resetting its timeout.
3311 This is not a problem when such interrupts are rare. Somebody set up a cron
3312 job to run exiwhat every 2 minutes, which is less than the normal select()
3313 timeout (5 or 10 minutes). This meant that the select() timeout never
3314 kicked in because it was always reset. I have fixed this by comparing the
3315 time when an interrupt arrives with the time at the start of the first call
3316 to select(). If more time than the timeout has elapsed, the interrupt is
3317 treated as a timeout.
3318
3319 5. Some internal re-factoring in preparation for the addition of Sieve
3320 extensions (by MH). In particular, the "personal" test is moved to a
3321 separate function, and given an option for scanning Cc: and Bcc: (which is
3322 not set for Exim filters).
3323
3324 6. When Exim created an email address using the login of the caller as the
3325 local part (e.g. when creating a From: or Sender: header line), it was not
3326 quoting the local part when it contained special characters such as @.
3327
3328 7. Installed new OpenBSD configuration files.
3329
3330 8. Reworded some messages for syntax errors in "and" and "or" conditions to
3331 try to make them clearer.
3332
3333 9. Callout options, other than the timeout value, were being ignored when
3334 verifying sender addresses in header lines. For example, when using
3335
3336 verify = header_sender/callout=no_cache
3337
3338 the cache was (incorrectly) being used.
3339
334010. Added a missing instance of ${EXE} to the exim_install script; this affects
3341 only the Cygwin environment.
3342
334311. When return_path_on_delivery was set as a log selector, if different remote
3344 addresses in the same message used different return paths and parallel
3345 remote delivery occurred, the wrong values would sometimes be logged.
3346 (Whenever a remote delivery process finished, the return path value from
3347 the most recently started remote delivery process was logged.)
3348
334912. RFC 3848 specifies standard names for the "with" phrase in Received: header
3350 lines when AUTH and/or TLS are in use. This is the "received protocol"
3351 field. Exim used to use "asmtp" for authenticated SMTP, without any
3352 indication (in the protocol name) for TLS use. Now it follows the RFC and
3353 uses "esmtpa" if the connection is authenticated, "esmtps" if it is
3354 encrypted, and "esmtpsa" if it is both encrypted and authenticated. These
3355 names appear in log lines as well as in Received: header lines.
3356
335713. Installed MH's patches for Sieve to add the "copy" and "vacation"
3358 extensions, and comparison tests, and to fix some bugs.
3359
336014. Changes to the "personal" filter test:
3361
3362 (1) The test was buggy in that it was just doing the equivalent of
3363 "contains" tests on header lines. For example, if a user's address was
3364 anne@some.where, the "personal" test would incorrectly be true for
3365
3366 To: susanne@some.where
3367
3368 This test is now done by extracting each address from the header in turn,
3369 and checking the entire address. Other tests that are part of "personal"
3370 are now done using regular expressions (for example, to check local parts
3371 of addresses in From: header lines).
3372
3373 (2) The list of non-personal local parts in From: addresses has been
3374 extended to include "listserv", "majordomo", "*-request", and "owner-*",
3375 taken from the Sieve specification recommendations.
3376
3377 (3) If the message contains any header line starting with "List-" it is
3378 treated as non-personal.
3379
3380 (4) The test for "circular" in the Subject: header line has been removed
3381 because it now seems ill-conceived.
3382
338315. Minor typos in src/EDITME comments corrected.
3384
338516. Installed latest exipick from John Jetmore.
3386
338717. If headers_add on a router specified a text string that was too long for
3388 string_sprintf() - that is, longer than 8192 bytes - Exim panicked. The use
3389 of string_sprintf() is now avoided.
3390
339118. $message_body_size was not set (it was always zero) when running the DATA
3392 ACL and the local_scan() function.
3393
339419. For the "mail" command in an Exim filter, no default was being set for
3395 the once_repeat time, causing a random time value to be used if "once" was
3396 specified. (If the value happened to be <= 0, no repeat happened.) The
3397 default is now 0s, meaning "never repeat". The "vacation" command was OK
3398 (its default is 7d). It's somewhat surprising nobody ever noticed this bug
3399 (I found it when inspecting the code).
3400
340120. There is now an overall timeout for performing a callout verification. It
3402 defaults to 4 times the callout timeout, which applies to individual SMTP
3403 commands during the callout. The overall timeout applies when there is more
3404 than one host that can be tried. The timeout is checked before trying the
3405 next host. This prevents very long delays if there are a large number of
3406 hosts and all are timing out (e.g. when the network connections are timing
3407 out). The value of the overall timeout can be changed by specifying an
3408 additional sub-option for "callout", called "maxwait". For example:
3409
3410 verify = sender/callout=5s,maxwait=20s
3411
341221. Add O_APPEND to the open() call for maildirsize files (Exim already seeks
3413 to the end before writing, but this should make it even safer).
3414
341522. Exim was forgetting that it had advertised PIPELINING for the second and
3416 subsequent messages on an SMTP connection. It was also not resetting its
3417 memory on STARTTLS and an internal HELO.
3418
341923. When Exim logs an SMTP synchronization error within a session, it now
3420 records whether PIPELINING has been advertised or not.
3421
342224. Added 3 instances of "(long int)" casts to time_t variables that were being
3423 formatted using %ld, because on OpenBSD (and perhaps others), time_t is int
3424 rather than long int.
3425
342625. Installed the latest Cygwin configuration files from the Cygwin maintainer.
3427
342826. Added the never_mail option to autoreply.
3429
3430
3431Exim version 4.41
3432-----------------
3433
3434 1. A reorganization of the code in order to implement 4.40/8 caused a daemon
3435 crash if the getsockname() call failed; this can happen if a connection is
3436 closed very soon after it is established. The problem was simply in the
3437 order in which certain operations were done, causing Exim to try to write
3438 to the SMTP stream before it had set up the file descriptor. The bug has
3439 been fixed by making things happen in the correct order.
3440
3441
3442Exim version 4.40
3443-----------------
3444
3445 1. If "drop" was used in a DATA ACL, the SMTP output buffer was not flushed
3446 before the connection was closed, thus losing the rejection response.
