13Exim version 4.85
14-----------------
15TL/01 When running the test suite, the README says that variables such as
16 no_msglog_check are global and can be placed anywhere in a specific
17 test's script, however it was observed that placement needed to be near
18 the beginning for it to behave that way. Changed the runtest perl
19 script to read through the entire script once to detect and set these
20 variables, reset to the beginning of the script, and then run through
21 the script parsing/test process like normal.

TL
23TL/02 The BSD's have an arc4random API. One of the functions to induce
24 adding randomness was arc4random_stir(), but it has been removed in
25 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
26 function when detected.

JH
28JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
29 cause callback expansion.
30
6286d7c4
TL
31TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
32 syntax errors in an expansion can be treated as a string instead of
33 logging or causing an error, due to the internal use of bool_lax
34 instead of bool when processing it.
35
0f06b4f2 36JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d

WB
48JH/05 Fix results-pipe from transport process. Several recipients, combined
49 with certificate use, exposed issues where response data items split
50 over buffer boundaries were not parsed properly. This eventually
51 resulted in duplicates being sent. This issue only became common enough
52 to notice due to the introduction of conection certificate information,
53 the item size being so much larger. Found and fixed by Wolfgang Breyha.
54
8bc732e8
JH
55JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
56 size buffer was used, resulting in syntax errors when an expansion
57 exceeded it.
58
a7fec7a7
JH
59JH/07 Add support for directories of certificates when compiled with a GnuTLS
60 version 3.3.6 or later.
61
774ef2d7
JH
62JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
63 is EXPERIMENTAL_EVENT, the main-configuration and transport options
64 both become "event_action", the variables become $event_name, $event_data
aec45841 65 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
66 routers, transports and related events. The tls:cert event is now also
67 raised for inbound connections, if the main configuration event_action
68 option is defined.

70TL/06 In test suite, disable OCSP for old versions of openssl which contained
71 early OCSP support, but no stapling (appears to be less than 1.0.0).
72
8d692470
JH
73JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
74 server certificate names available under the smtp transport option
75 "tls_verify_cert_hostname" now do not permit multi-component wildcard
76 matches.
77
e9477a08
JH
78JH/10 Time-related extraction expansions from certificates now use the main
79 option "timezone" setting for output formatting, and are consistent
80 between OpenSSL and GnuTLS compilations. Bug 1541.
81

122Exim version 4.83
123-----------------
124
125TF/01 Correctly close the server side of TLS when forking for delivery.
126
127 When a message was received over SMTP with TLS, Exim failed to clear up
128 the incoming connection properly after forking off the child process to
129 deliver the message. In some situations the subsequent outgoing
130 delivery connection happened to have the same fd number as the incoming
131 connection previously had. Exim would try to use TLS and fail, logging
132 a "Bad file descriptor" error.
133

134TF/02 Portability fix for building lookup modules on Solaris when the xpg4
135 utilities have not been installed.

TL
163 results permerror and temperror. Previous values are deprecated but
164 still accepted. In a future release, err_perm and err_temp will be
165 completely removed, which will be a backward incompatibility if the
166 ACL tests for either of these two old results. Patch contributed by

191JH/12 Expand items in router/transport headers_add or headers_remove lists
192 individually rather than the list as a whole. Bug 1452.
193
194 Required for reasonable handling of multiple headers_ options when
195 they may be empty; requires that headers_remove items with embedded

378TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
379
380 When a queue runner is handling a message, Exim first routes the
381 recipient addresses, during which it prunes them based on the retry
382 hints database. After that it attempts to deliver the message to
383 any remaining recipients. It then updates the hints database using
384 the retry rules.
385
386 So if a recipient address works intermittently, it can get repeatedly
387 deferred at routing time. The retry hints record remains fresh so the
388 address never reaches the final cutoff time.
389
390 This is a fairly common occurrence when a user is bumping up against
391 their storage quota. Exim had some logic in its local delivery code
392 to deal with this. However it did not apply to per-recipient defers
393 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
394
1ddeb334
TF
395 This change adds a proper retry rule check during routing so that the
396 final cutoff time is checked against the message's age. We only do
397 this check if there is an address retry record and there is not a
398 domain retry record; this implies that previous attempts to handle
399 the address had the retry_use_local_parts option turned on. We use
400 this as an approximation for the destination being like a local
401 delivery, as in LMTP.
67bd1ab3
TF
402
403 I suspect this new check makes the old local delivery cutoff check
404 redundant, but I have not verified this so I left the code in place.

408 Test 0254 submits a message to Exim with the header

410 Resent-From: f
411
412 When I ran the test suite under the user fanf2, Exim expanded
413 the header to contain my full name, whereas it should have added
414 a Resent-Sender: header. It erroneously treats any prefix of the
415 username as equal to the username.

438JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
439 Server implementation by Todd Lyons, client by JH.
440 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
441 config variable "prdr_enable" controls whether the server
442 advertises the facility. If the client requests PRDR a new
443 acl_data_smtp_prdr ACL is called once for each recipient, after
444 the body content is received and before the acl_smtp_data ACL.
445 The client is controlled by bolth of: a hosts_try_prdr option
446 on the smtp transport, and the server advertisement.
447 Default client logging of deliveries and rejections involving
448 PRDR are flagged with the string "PRDR".

726TF/03 Make the exiwhat support code safe for signals. Previously Exim might
727 lock up or crash if it happened to be inside a call to libc when it
728 got a SIGUSR1 from exiwhat.
729
730 The SIGUSR1 handler appends the current process status to the process
731 log which is later printed by exiwhat. It used to use the general
732 purpose logging code to do this, but several functions it calls are
733 not safe for signals.
734
735 The new output code in the SIGUSR1 handler is specific to the process
736 log, and simple enough that it's easy to inspect for signal safety.
737 Removing some special cases also simplifies the general logging code.
738 Removing the spurious timestamps from the process log simplifies
739 exiwhat.

c99ce5c9
TF
741TF/04 Improved ratelimit ACL condition.
742
743 The /noupdate option has been deprecated in favour of /readonly which
744 has clearer semantics. The /leaky, /strict, and /readonly update modes
745 are mutually exclusive. The update mode is no longer included in the
746 database key; it just determines when the database is updated. (This
747 means that when you upgrde Exim will forget old rate measurements.)
748
749 Exim now checks that the per_* options are used with an update mode that
750 makes sense for the current ACL. For example, when Exim is processing a
751 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
752 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
753 must specify per_mail/readonly. If you omit the update mode it defaults to
754 /leaky where that makes sense (as before) or /readonly where required.
755
756 The /noupdate option is now undocumented but still supported for
757 backwards compatibility. It is equivalent to /readonly except that in
758 ACLs where /readonly is required you may specify /leaky/noupdate or
759 /strict/noupdate which are treated the same as /readonly.
760
761 A useful new feature is the /count= option. This is a generalization
762 of the per_byte option, so that you can measure the throughput of other
763 aggregate values. For example, the per_byte option is now equivalent
764 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
765
766 The per_rcpt option has been generalized using the /count= mechanism
767 (though it's more complicated than the per_byte equivalence). When it is
768 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
769 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
770 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
771 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
772 Note that using per_rcpt with a non-readonly update mode in more than
773 one ACL will cause the recipients to be double-counted. (The per_mail
774 and per_byte options don't have this problem.)
775
776 The handling of very low rates has changed slightly. If the computed rate
777 is less than the event's count (usually one) then this event is the first
778 after a long gap. In this case the rate is set to the same as this event's
779 count, so that the first message of a spam run is counted properly.
780
781 The major new feature is a mechanism for counting the rate of unique
782 events. The new per_addr option counts the number of different
783 recipients that someone has sent messages to in the last time period. It
784 behaves like per_rcpt if all the recipient addresses are different, but
785 duplicate recipient addresses do not increase the measured rate. Like
786 the /count= option this is a general mechanism, so the per_addr option
787 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
788 example, measure the rate that a client uses different sender addresses
789 with the options per_mail/unique=$sender_address. There are further
790 details in the main documentation.

1339
1340 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1341 were called 'true' and it seems that C99 defines that as a reserved
1342 keyword to be used with 'bool' variable types. That means you could
1343 not include C99-style headers which use bools without triggering
1344 build errors in sieve.c.

1359Exim version 4.68
1360-----------------
1361
1362PH/01 Another patch from the Sieve maintainer.
1363
6a3bceb1
PH
1364PH/02 When an IPv6 address is converted to a string for single-key lookup
1365 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1366 dots are used instead of colons so that keys in lsearch files need not
1367 contain colons. This was done some time before quoting was made available
1368 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1369 (notated using the quote facility) so as to distinguish them from IPv4
1370 keys. This meant that lookups for IP addresses in host lists did not work
1371 for iplsearch lookups.
1372
1373 This has been fixed by arranging for IPv6 addresses to be expressed with
1374 colons if the lookup type is iplsearch. This is not incompatible, because
1375 previously such lookups could never work.
1376
1377 The situation is now rather anomolous, since one *can* have colons in
1378 ordinary lsearch keys. However, making the change in all cases is
1379 incompatible and would probably break a number of configurations.

MH
1384MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1385 conversion specification without a maximum field width, thereby enabling
1386 a rogue spamd server to cause a buffer overflow. While nobody in their
1387 right mind would setup Exim to query an untrusted spamd server, an
1388 attacker that gains access to a server running spamd could potentially
1389 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1394MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1395 a directory entry by the name of the lookup key. Previously, if a
1396 symlink pointed to a non-existing file or a file in a directory that
1397 Exim lacked permissions to read, a lookup for a key matching that
1398 symlink would fail. Now it is enough that a matching directory entry
1399 exists, symlink or not. (Bugzilla 503.)

1475
1476 if a client was not listed at all, or was listed with a value other than
1477 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1478 the condition was not true (as it should be), so access was not denied.
1479 The bug was that the ! inversion was incorrectly passed on to the second
1480 item. This has been fixed.

1580 were accidentally chopped off.

PH
1582PH/29 SMTP synchronization checks are implemented when a command is read -
1583 there is a check that no more input is waiting when there shouldn't be
1584 any. However, for some commands, a delay in an ACL can mean that it is
1585 some time before the response is written. In this time, more input might
1586 arrive, invalidly. So now there are extra checks after an ACL has run for
1587 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1588 pipelining has not been advertised.

1603 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1604 was a macro that became an assignment, so it seemed to work. This has

1664 (unfortunately, this is allowed). However, in many cases there won't be
1665 any further data because there won't be any more messages to send. A call
1666 to select() can be used: if it shows that the input is "ready", there is
1667 either input waiting, or the socket has been closed. An attempt to read
1668 the next input character can distinguish the two cases. Previously, Exim

1680PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1681 fixed by 4.65/MH/01 (is this a record?) are fixed:
1682
1683 (i) An empty string was always treated as zero by the numeric comparison
1684 operators. This behaviour has been restored.
1685
1686 (ii) It is documented that the numeric comparison operators always treat
1687 their arguments as decimal numbers. This was broken in that numbers
1688 starting with 0 were being interpreted as octal.
1689
1690 While fixing these problems I realized that there was another issue that
1691 hadn't been noticed. Values of message_size_limit (both the global option
1692 and the transport option) were treated as octal if they started with 0.
1693 The documentation was vague. These values are now always treated as
1694 decimal, and I will make that clear in the documentation.

PH
1738PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1739 callout verification, Exim cached a "reject" for the entire domain. This
1740 is correct for most verifications, but it is not correct for a recipient
1741 verification with use_sender or use_postmaster set, because in that case
1742 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1743 case of MAIL FROM:<> rejection from other early rejections (e.g.
1744 rejection of HELO). When verifying a recipient using a non-null MAIL
1745 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1746 Whatever the result of the callout, the value of the domain cache is
1747 left unchanged (for any other kind of callout, getting as far as trying
1748 RCPT means that the domain itself is ok).

1784 probably the interface on which it is arriving) and not to the outgoing
1785 callout (which could be using a different interface). This has been
1786 changed to use the value of the helo_data option from the smtp transport
1787 instead - this is what is used when a message is actually being sent. If
1788 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
1793 (a) The code assumed that strncpy() returns a negative number on buffer
1794 overflow, which isn't the case. Replaced with Exim's string_format()
1795 function.
1796 (b) There were several signed/unsigned issues. I just did the minimum
1797 hacking in of casts. There is scope for a larger refactoring.
1798 (c) The code used strcasecmp() which is not a standard C function.
1799 Replaced with Exim's strcmpic() function.
1800 (d) The code set only $1; it now sets $auth1 as well.
1801 (e) A simple test gave the error "authentication client didn't specify
1802 service in request". It would seem that Dovecot has changed its
1803 interface. Fortunately there's a specification; I followed it and
1804 changed what the client sends and it appears to be working now.

1811 -v the output is "A verified" because verification stops after a
1812 successful redirection if more than one address is generated. However,
1813 with -v the child addresses are also verified. Exim was outputting "A
1814 failed to verify" and then showing the successful verification for C,
1815 with its parentage. It now outputs "B failed to verify", showing B's
1816 parentage before showing the successful verification of C.

PH
1822PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1823 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1824 they consult the DNS. I had assumed they would set it the way they
1825 wanted; and indeed my experiments on Linux seem to show that in some
1826 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1827 To be on the safe side, however, I have now made the interface to
1828 host_find_byname() similar to host_find_bydns(), with an argument
1829 containing the DNS resolver options. The host_find_byname() function now
1830 sets these options at its start, just as host_find_bydns() does. The smtp
1831 transport options dns_qualify_single and dns_search_parents are passed to
1832 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1833 of host_find_byname() use the default settings of RES_DEFNAMES
1834 (qualify_single) but not RES_DNSRCH (search_parents).

1836PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1837 spool_read_header() do less string testing, by means of a preliminary
1838 switch on the second character of optional "-foo" lines. (This is
1839 overdue, caused by the large number of possibilities that now exist.
1840 Originally there were few.) While I was there, I also converted the
1841 str(n)cmp tests so they don't re-test the leading "-" and the first
1842 character, in the hope this might squeeze out yet more improvement.

1844PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1845 flag allowing group syntax was set by the header_syntax check but not
1846 turned off, possible causing trouble later; (2) The flag was not being
1847 set at all for the header_verify test, causing "group"-style headers to
1848 be rejected. I have now set it in this case, and also caused header_
1849 verify to ignore an empty address taken from a group. While doing this, I
1850 came across some other cases where the code for allowing group syntax
1851 while scanning a header line wasn't quite right (mostly, not resetting
1852 the flag correctly in the right place). These bugs could have caused
1853 trouble for malformed header lines. I hope it is now all correct.

1855PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1861PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

1864 only MTA that supported it -- and would never use it because real RSA is
1865 always available. This code has been removed, because it had the bad
1866 effect of slowing Exim down by computing (never used) parameters for the

1906
1907PH/30 Exim was sometimes attempting to deliver messages that had suffered
1908 address errors (4xx response to RCPT) over the same connection as other
1909 messages routed to the same hosts. Such deliveries are always "forced",
1910 so retry times are not inspected. This resulted in far too many retries
1911 for the affected addresses. The effect occurred only when there were more
1912 hosts than the hosts_max_try setting in the smtp transport when it had
1913 the 4xx errors. Those hosts that it had tried were not added to the list
1914 of hosts for which the message was waiting, so if all were tried, there
1915 was no problem. Two fixes have been applied:
1916
1917 (i) If there are any address or message errors in an SMTP delivery, none
1918 of the hosts (tried or untried) are now added to the list of hosts
1919 for which the message is waiting, so the message should not be a
1920 candidate for sending over the same connection that was used for a
1921 successful delivery of some other message. This seems entirely
1922 reasonable: after all the message is NOT "waiting for some host".
1923 This is so "obvious" that I'm not sure why it wasn't done
1924 previously. Hope I haven't missed anything, but it can't do any
1925 harm, as the worst effect is to miss an optimization.
1926
1927 (ii) If, despite (i), such a delivery is accidentally attempted, the
1928 routing retry time is respected, so at least it doesn't keep
1929 hammering the server.

1944PH/35 The error "getsockname() failed: connection reset by peer" was being
1945 written to the panic log as well as the main log, but it isn't really

48c7f9e2
PH
1950PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1951 runs only) independently of the message's sender address. This meant
1952 that, if the 4xx error was in fact related to the sender, a different
1953 message to the same recipient with a different sender could confuse
1954 things. In particualar, this can happen when sending to a greylisting
1955 server, but other circumstances could also provoke similar problems.
1956 I have changed the default so that the retry time for these errors is now
1957 based a combination of the sender and recipient addresses. This change
1958 can be overridden by setting address_retry_include_sender=false in the
1959 smtp transport.

2227PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2229 Unfortunately, if there is a major crisis, such as a disk failure,
2230 tcp-wrappers gives "deny", whereas what one would like would be some
2231 kind of temporary error. A kludge has been added to help with this.
2232 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2233 554 error is used if errno is still zero or contains ENOENT (which occurs
2234 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2235 451 error is used.

2275 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2320 autoreply, Exim could try to deliver to a non-existent relative file

2355 additional section of a DNS packet that returns MX or SRV records.
2356 Instead, it always explicitly searches for A/AAAA records. This avoids
2357 major problems that occur when a DNS server includes only records of one
2358 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2359 fixed another bug: if SRV records were looked up and the corresponding
2360 address records were *not* found in the additional section, the port
2361 values from the SRV records were lost.

2363PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2367PH/18 If quota_warn_message contains a From: header, Exim now refrains from

PH
2371PH/19 When calculating a retry time, Exim used to measure the "time since
2372 failure" by looking at the "first failed" field in the retry record. Now
2373 it does not use this if it is later than than the arrival time of the
2374 message. Instead it uses the arrival time. This makes for better
2375 behaviour in cases where some deliveries succeed, thus re-setting the
2376 "first failed" field. An example is a quota failure for a huge message
2377 when small messages continue to be delivered. Without this change, the
2378 "time since failure" will always be short, possible causing more frequent
2379 delivery attempts for the huge message than are intended.

PH
2476PH/42 The content-scanning code uses fopen() to create files in which to put
2477 message data. Previously it was not paying any attention to the mode of
2478 the files. Exim runs with umask(0) because the rest of the code creates
2479 files with open(), and sets the required mode explicitly. Thus, these
2480 files were ending up world-writeable. This was not a big issue, because,
2481 being within the spool directory, they were not world-accessible. I have
2482 created a function called modefopen, which takes an additional mode
2483 argument. It sets umask(777), creates the file, chmods it to the required
2484 mode, then resets the umask. All the relevant calls to fopen() in the
2485 content scanning code have been changed to use this function.

2522
2523 (i) Exim was not creating retry information for temporary errors given
2524 for individual recipients after the DATA command when the smtp transport
2525 was used in LMTP mode. This meant that they could be retried too
2526 frequently, and not timed out correctly.
2527
2528 (ii) Exim was setting the flag that allows error details to be returned
2529 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2530 recipients that were returned after the DATA command.
2531
2532PH/53 This is related to PH/52, but is more general: for any failing address,
2533 when detailed error information was permitted to be returned to the
2534 sender, but the error was temporary, then after the final timeout, only
2535 "retry timeout exceeded" was returned. Now it returns the full error as

2606PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2607 function verify_get_ident() calls ip_connect() to connect a socket, but
2608 if the "connect()" function timed out, ip_connect() used to close the
2609 socket. However, verify_get_ident() also closes the socket later, and in
2610 between Exim writes to the log, which may get opened at this point. When
2611 the socket was closed in ip_connect(), the log could get the same file
2612 descriptor number as the socket. This naturally causes chaos. The fix is
2613 not to close the socket in ip_connect(); the socket should be closed by
2614 the function that creates it. There was only one place in the code where
2615 this was missing, in the iplookup router, which I don't think anybody now
2616 uses, but I've fixed it anyway.

2678 Received: from [1.2.3.4] (helo=[1.2.3.4])

2757 extension "envelope-auth". The code is finished and in agreement with
2758 other implementations, but there is no documentation so far and in fact,
2759 nobody wrote the draft yet. This extension is currently #undef'ed, thus
2760 not changing the active code.
2761
2762 Print executed "if" and "elsif" statements when debugging is used. This
2763 helps a great deal to understand what a filter does.

PH
2771PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2772 canonical form (as documented). However, after a host name lookup from
2773 the IP address, check_host() was doing a simple string comparison with
2774 addresses acquired from the DNS when checking that the found name did
2775 have the original IP as one of its addresses. Since any found IPv6
2776 addresses are likely to be in abbreviated form, the comparison could
2777 fail. Luckily, there already exists a function for doing the comparison
2778 by converting both addresses to binary, so now that is used instead of
2779 the text comparison.
2780
96776534
PH
2781PH/20 There was another similar case to PH/19, when a complete host name was
2782 given in a host list; looking up its IP address could give an abbreviated
2783 form, whereas the current host's name might or might not be abbreviated.
2784 The same fix has been applied.

3079 preserve the sysexits.h value, by assumimg that macro definitions were

3154PH/15 The code I had for printing potentially long long variables in PH/11
3155 above was not the best (it lost precision). The length of off_t variables
3156 is now inspected at build time, and an appropriate printing format (%ld

PH
3157 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3158 to be "long long int" or "long int". This is needed for the internal
3159 formatting function string_vformat().

3161PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3162 the configuration file to be ":syslog", then the script "guesses" where
3163 the logs files are, rather than using the compiled in default. In our
3164 case the guess is not the same as the compiled default, so the script
3165 suddenly stopped working when I started to use syslog. The patch checks
3166 to see if log_file_path is "". If so, it attempts to read it from exim
3167 with no configuration file to get the compiled in version, before it
3168 falls back to the previous guessing code."

3177PH/18 If the "use_postmaster" option was set for a recipient callout together

3180 test. It is now used for both.

3182PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3183 patch removes a few documentation additions to RFC 3028, because the
3184 latest draft now contains them. It adds the new en;ascii-case comparator
3185 and a new error check for 8bit text in MIME parts. Comparator and
3186 require names are now matched exactly. I enabled the subaddress
3187 extension, but it is not well tested yet (read: it works for me)."

3189PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3190 rework some of the code of TK/09 above to avoid the hardwired use of

3198PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3199 experimental DomainKeys support:
3200
3201 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3202 (2) On an error such as an illegally used "control", the wrong name for
3203 the control was given.

PH
3211PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3212 databases so that it will be absolutely obvious if a crash occurs in the
3213 DB library. This is a regular occurrence (often caused by mis-matched
3214 db.h files).
3215
ff790e47 3216PH/26 Insert a lot of missing (void) casts for functions such as chown(),

PH
3217 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3218 picked up on a user's system that detects such things. There doesn't seem
3219 to be a gcc warning option for this - only an attribute that has to be
3220 put on the function's prototype. It seems that in Fedora Core 4 they have
3221 set this on a number of new functions. No doubt there will be more in due
3222 course.

PH
3224PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3225 specify a transport. However, if an address that was verified by such a
3226 router was the subject of a callout, Exim crashed because it tried to
3227 read the rcpt_include_affixes from the non-existent transport. Now it
3228 just assumes that the setting of that option is false. This bug was
3229 introduced by 4.51/PH/31.

3239PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3240 aren't the modern standard, and it seems that some systems' include files
3241 don't always have them. Exim was already checking for some of the newer
3242 ones like T_AAAA, and defining it itself. I've added checks for all the
3243 record types that Exim uses.

PH
3245PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3246 not automatically generating a new one, as it is supposed to. This
3247 prevented TLS from working. If the file did exist, but contained invalid
3248 data, a new version was generated, as expected. It was only the case of a
3249 non-existent file that was broken.

3260PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3261 the use of a port name that isn't defined in /etc/services) occurred, the
3262 message was deferred as in a normal delivery, and thus remained on the
3263 spool, instead of being failed because of the mua_wrapper setting. This
3264 is now fixed, and I tidied up some of the mua_wrapper messages at the
3265 same time.

3267SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3295 to test Sieve filters that use "vacation".
3296
3297PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3298 that changes the way the GnuTLS parameters are stored in the cache file.
3299 The new format can be generated externally. For backward compatibility,
3300 if the data in the cache doesn't make sense, Exim assumes it has read an
3301 old-format file, and it generates new data and writes a new file. This
3302 means that you can't go back to an older release without removing the
3303 file.
3304
3305PH/03 A redirect router that has both "unseen" and "one_time" set does not
3306 work if there are any delivery delays because "one_time" forces the
3307 parent to be marked "delivered", so its unseen clone is never tried
3308 again. For this reason, Exim now forbids the simultaneous setting of
3309 these two options.
3310
3311PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3312 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3313 entry if you want to know the details. The fix, however, neglected to
3314 consider the case when local delivery batching is involved. The test for
3315 "previously delivered" was not happening when checking to see if an
3316 address could be batched with a previous (undelivered) one; under
3317 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3318 address.
1a46a8c5
PH
3319
3320PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3321 in its include files, and this causes problems building Exim.
3322
3323PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3324 header_syntax) but Exim was just ignoring anything given after a slash.
3325 In particular, this caused confusion with an attempt to use "verify =
3326 reverse_host_lookup/defer_ok". An error is now given when options are
3327 supplied for verify items that do not have them. (Maybe reverse_host_
3328 lookup should have a defer_ok option, but that's a different point.)
3329
3330PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3331 defined by RFC 821) to 2048, because there were problems with some AUTH
3332 commands, and RFC 1869 says the size should be increased for extended
3333 SMTP commands that take arguments.

3335PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3336 Finch).
