5Exim version 4.85
6-----------------
7TL/01 When running the test suite, the README says that variables such as
8 no_msglog_check are global and can be placed anywhere in a specific
9 test's script, however it was observed that placement needed to be near
10 the beginning for it to behave that way. Changed the runtest perl
11 script to read through the entire script once to detect and set these
12 variables, reset to the beginning of the script, and then run through
13 the script parsing/test process like normal.

15TL/02 The BSD's have an arc4random API. One of the functions to induce
16 adding randomness was arc4random_stir(), but it has been removed in
17 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
18 function when detected.

TL
23TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
24 syntax errors in an expansion can be treated as a string instead of
25 logging or causing an error, due to the internal use of bool_lax
26 instead of bool when processing it.

40JH/05 Fix results-pipe from transport process. Several recipients, combined
41 with certificate use, exposed issues where response data items split
42 over buffer boundaries were not parsed properly. This eventually
43 resulted in duplicates being sent. This issue only became common enough
44 to notice due to the introduction of conection certificate information,
45 the item size being so much larger. Found and fixed by Wolfgang Breyha.
46
8bc732e8
JH
47JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
48 size buffer was used, resulting in syntax errors when an expansion
49 exceeded it.

52 version 3.3.6 or later.
53

JH
54JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
55 is EXPERIMENTAL_EVENT, the main-configuration and transport options
56 both become "event_action", the variables become $event_name, $event_data
aec45841 57 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
58 routers, transports and related events. The tls:cert event is now also
59 raised for inbound connections, if the main configuration event_action
60 option is defined.

65JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on

67 "tls_verify_cert_hostname" now do not permit multi-component wildcard
68 matches.

74JH/11 Fix a crash in mime ACL when meeting a zero-length parameter in the
75 incoming message.

78 include certificate info, eximon was claiming there were spoolfile
79 syntax errors.

102Exim version 4.83
103-----------------
104
105TF/01 Correctly close the server side of TLS when forking for delivery.
106
107 When a message was received over SMTP with TLS, Exim failed to clear up
108 the incoming connection properly after forking off the child process to
109 deliver the message. In some situations the subsequent outgoing
110 delivery connection happened to have the same fd number as the incoming
111 connection previously had. Exim would try to use TLS and fail, logging
112 a "Bad file descriptor" error.

115 utilities have not been installed.

358TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
359
360 When a queue runner is handling a message, Exim first routes the
361 recipient addresses, during which it prunes them based on the retry
362 hints database. After that it attempts to deliver the message to
363 any remaining recipients. It then updates the hints database using
364 the retry rules.
365
366 So if a recipient address works intermittently, it can get repeatedly
367 deferred at routing time. The retry hints record remains fresh so the
368 address never reaches the final cutoff time.
369
370 This is a fairly common occurrence when a user is bumping up against
371 their storage quota. Exim had some logic in its local delivery code
372 to deal with this. However it did not apply to per-recipient defers
373 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
374
1ddeb334
TF
375 This change adds a proper retry rule check during routing so that the
376 final cutoff time is checked against the message's age. We only do
377 this check if there is an address retry record and there is not a
378 domain retry record; this implies that previous attempts to handle
379 the address had the retry_use_local_parts option turned on. We use
380 this as an approximation for the destination being like a local
381 delivery, as in LMTP.
67bd1ab3
TF
382
383 I suspect this new check makes the old local delivery cutoff check
384 redundant, but I have not verified this so I left the code in place.

390 Resent-From: f
391
392 When I ran the test suite under the user fanf2, Exim expanded
393 the header to contain my full name, whereas it should have added
394 a Resent-Sender: header. It erroneously treats any prefix of the
395 username as equal to the username.
396
397 This change corrects that bug.

418JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
419 Server implementation by Todd Lyons, client by JH.
420 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
421 config variable "prdr_enable" controls whether the server
422 advertises the facility. If the client requests PRDR a new
423 acl_data_smtp_prdr ACL is called once for each recipient, after
424 the body content is received and before the acl_smtp_data ACL.
425 The client is controlled by bolth of: a hosts_try_prdr option
426 on the smtp transport, and the server advertisement.
427 Default client logging of deliveries and rejections involving
428 PRDR are flagged with the string "PRDR".

706TF/03 Make the exiwhat support code safe for signals. Previously Exim might
707 lock up or crash if it happened to be inside a call to libc when it
708 got a SIGUSR1 from exiwhat.
709
710 The SIGUSR1 handler appends the current process status to the process
711 log which is later printed by exiwhat. It used to use the general
712 purpose logging code to do this, but several functions it calls are
713 not safe for signals.
714
715 The new output code in the SIGUSR1 handler is specific to the process
716 log, and simple enough that it's easy to inspect for signal safety.
717 Removing some special cases also simplifies the general logging code.
718 Removing the spurious timestamps from the process log simplifies
719 exiwhat.
720
c99ce5c9
TF
721TF/04 Improved ratelimit ACL condition.
722
723 The /noupdate option has been deprecated in favour of /readonly which
724 has clearer semantics. The /leaky, /strict, and /readonly update modes
725 are mutually exclusive. The update mode is no longer included in the
726 database key; it just determines when the database is updated. (This
727 means that when you upgrde Exim will forget old rate measurements.)
728
729 Exim now checks that the per_* options are used with an update mode that
730 makes sense for the current ACL. For example, when Exim is processing a
731 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
732 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
733 must specify per_mail/readonly. If you omit the update mode it defaults to
734 /leaky where that makes sense (as before) or /readonly where required.
735
736 The /noupdate option is now undocumented but still supported for
737 backwards compatibility. It is equivalent to /readonly except that in
738 ACLs where /readonly is required you may specify /leaky/noupdate or
739 /strict/noupdate which are treated the same as /readonly.
740
741 A useful new feature is the /count= option. This is a generalization
742 of the per_byte option, so that you can measure the throughput of other
743 aggregate values. For example, the per_byte option is now equivalent
744 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
745
746 The per_rcpt option has been generalized using the /count= mechanism
747 (though it's more complicated than the per_byte equivalence). When it is
748 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
749 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
750 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
751 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
752 Note that using per_rcpt with a non-readonly update mode in more than
753 one ACL will cause the recipients to be double-counted. (The per_mail
754 and per_byte options don't have this problem.)
755
756 The handling of very low rates has changed slightly. If the computed rate
757 is less than the event's count (usually one) then this event is the first
758 after a long gap. In this case the rate is set to the same as this event's
759 count, so that the first message of a spam run is counted properly.
760
761 The major new feature is a mechanism for counting the rate of unique
762 events. The new per_addr option counts the number of different
763 recipients that someone has sent messages to in the last time period. It
764 behaves like per_rcpt if all the recipient addresses are different, but
765 duplicate recipient addresses do not increase the measured rate. Like
766 the /count= option this is a general mechanism, so the per_addr option
767 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
768 example, measure the rate that a client uses different sender addresses
769 with the options per_mail/unique=$sender_address. There are further
770 details in the main documentation.

1319
1320 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1321 were called 'true' and it seems that C99 defines that as a reserved
1322 keyword to be used with 'bool' variable types. That means you could
1323 not include C99-style headers which use bools without triggering
1324 build errors in sieve.c.

1339Exim version 4.68
1340-----------------
1341
1342PH/01 Another patch from the Sieve maintainer.
1343
6a3bceb1
PH
1344PH/02 When an IPv6 address is converted to a string for single-key lookup
1345 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1346 dots are used instead of colons so that keys in lsearch files need not
1347 contain colons. This was done some time before quoting was made available
1348 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1349 (notated using the quote facility) so as to distinguish them from IPv4
1350 keys. This meant that lookups for IP addresses in host lists did not work
1351 for iplsearch lookups.
1352
1353 This has been fixed by arranging for IPv6 addresses to be expressed with
1354 colons if the lookup type is iplsearch. This is not incompatible, because
1355 previously such lookups could never work.
1356
1357 The situation is now rather anomolous, since one *can* have colons in
1358 ordinary lsearch keys. However, making the change in all cases is
1359 incompatible and would probably break a number of configurations.

MH
1364MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1365 conversion specification without a maximum field width, thereby enabling
1366 a rogue spamd server to cause a buffer overflow. While nobody in their
1367 right mind would setup Exim to query an untrusted spamd server, an
1368 attacker that gains access to a server running spamd could potentially
1369 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1374MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1375 a directory entry by the name of the lookup key. Previously, if a
1376 symlink pointed to a non-existing file or a file in a directory that
1377 Exim lacked permissions to read, a lookup for a key matching that
1378 symlink would fail. Now it is enough that a matching directory entry
1379 exists, symlink or not. (Bugzilla 503.)

1452PH/02 In an ACL statement such as

1455
1456 if a client was not listed at all, or was listed with a value other than
1457 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1458 the condition was not true (as it should be), so access was not denied.
1459 The bug was that the ! inversion was incorrectly passed on to the second

PH
1562PH/29 SMTP synchronization checks are implemented when a command is read -
1563 there is a check that no more input is waiting when there shouldn't be
1564 any. However, for some commands, a delay in an ACL can mean that it is
1565 some time before the response is written. In this time, more input might
1566 arrive, invalidly. So now there are extra checks after an ACL has run for
1567 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1568 pipelining has not been advertised.

1583 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1584 was a macro that became an assignment, so it seemed to work. This has
1585 changed to a proper function call with a void return, hence the compile
1586 error. Exim's code has been fixed.

1642 the response to the final '.' that terminates a message, but only in the

1644 (unfortunately, this is allowed). However, in many cases there won't be
1645 any further data because there won't be any more messages to send. A call
1646 to select() can be used: if it shows that the input is "ready", there is
1647 either input waiting, or the socket has been closed. An attempt to read
1648 the next input character can distinguish the two cases. Previously, Exim

1660PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1661 fixed by 4.65/MH/01 (is this a record?) are fixed:
1662
1663 (i) An empty string was always treated as zero by the numeric comparison
1664 operators. This behaviour has been restored.
1665
1666 (ii) It is documented that the numeric comparison operators always treat
1667 their arguments as decimal numbers. This was broken in that numbers
1668 starting with 0 were being interpreted as octal.
1669
1670 While fixing these problems I realized that there was another issue that
1671 hadn't been noticed. Values of message_size_limit (both the global option
1672 and the transport option) were treated as octal if they started with 0.
1673 The documentation was vague. These values are now always treated as
1674 decimal, and I will make that clear in the documentation.

1691 large number of recipients for a single message is ridiculous

PH
1718PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1719 callout verification, Exim cached a "reject" for the entire domain. This
1720 is correct for most verifications, but it is not correct for a recipient
1721 verification with use_sender or use_postmaster set, because in that case
1722 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1723 case of MAIL FROM:<> rejection from other early rejections (e.g.
1724 rejection of HELO). When verifying a recipient using a non-null MAIL
1725 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1726 Whatever the result of the callout, the value of the domain cache is
1727 left unchanged (for any other kind of callout, getting as far as trying
1728 RCPT means that the domain itself is ok).

1764 probably the interface on which it is arriving) and not to the outgoing
1765 callout (which could be using a different interface). This has been
1766 changed to use the value of the helo_data option from the smtp transport
1767 instead - this is what is used when a message is actually being sent. If
1768 there is no remote transport (possible with a router that sets up host

7befa435 1772 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1773 (a) The code assumed that strncpy() returns a negative number on buffer
1774 overflow, which isn't the case. Replaced with Exim's string_format()
1775 function.
1776 (b) There were several signed/unsigned issues. I just did the minimum
1777 hacking in of casts. There is scope for a larger refactoring.
1778 (c) The code used strcasecmp() which is not a standard C function.
1779 Replaced with Exim's strcmpic() function.
1780 (d) The code set only $1; it now sets $auth1 as well.
1781 (e) A simple test gave the error "authentication client didn't specify
1782 service in request". It would seem that Dovecot has changed its
1783 interface. Fortunately there's a specification; I followed it and
1784 changed what the client sends and it appears to be working now.

1790 address A is aliased to B and C, where B exists and C does not. Without
1791 -v the output is "A verified" because verification stops after a
1792 successful redirection if more than one address is generated. However,
1793 with -v the child addresses are also verified. Exim was outputting "A
1794 failed to verify" and then showing the successful verification for C,
1795 with its parentage. It now outputs "B failed to verify", showing B's
1796 parentage before showing the successful verification of C.

PH
1802PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1803 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1804 they consult the DNS. I had assumed they would set it the way they
1805 wanted; and indeed my experiments on Linux seem to show that in some
1806 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1807 To be on the safe side, however, I have now made the interface to
1808 host_find_byname() similar to host_find_bydns(), with an argument
1809 containing the DNS resolver options. The host_find_byname() function now
1810 sets these options at its start, just as host_find_bydns() does. The smtp
1811 transport options dns_qualify_single and dns_search_parents are passed to
1812 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1813 of host_find_byname() use the default settings of RES_DEFNAMES
1814 (qualify_single) but not RES_DNSRCH (search_parents).

1816PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1817 spool_read_header() do less string testing, by means of a preliminary
1818 switch on the second character of optional "-foo" lines. (This is
1819 overdue, caused by the large number of possibilities that now exist.
1820 Originally there were few.) While I was there, I also converted the
1821 str(n)cmp tests so they don't re-test the leading "-" and the first
1822 character, in the hope this might squeeze out yet more improvement.

1824PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1825 flag allowing group syntax was set by the header_syntax check but not
1826 turned off, possible causing trouble later; (2) The flag was not being
1827 set at all for the header_verify test, causing "group"-style headers to
1828 be rejected. I have now set it in this case, and also caused header_
1829 verify to ignore an empty address taken from a group. While doing this, I
1830 came across some other cases where the code for allowing group syntax
1831 while scanning a header line wasn't quite right (mostly, not resetting
1832 the flag correctly in the right place). These bugs could have caused
1833 trouble for malformed header lines. I hope it is now all correct.

1835PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1838 but it didn't always do it. This confused somebody who was copying the
1839 code for some other use. I have removed all the tests.

PH
1841PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1842 feature that was used to support insecure browsers during the U.S. crypto
1843 embargo. It requires special client support, and Exim is probably the
1844 only MTA that supported it -- and would never use it because real RSA is
1845 always available. This code has been removed, because it had the bad
1846 effect of slowing Exim down by computing (never used) parameters for the
1847 RSA_EXPORT functionality.

1853 if the connection is using TLS or if the remote IP is the same as the
1854 local IP, and the "valid-client-cert option" if a client certificate has

1886
1887PH/30 Exim was sometimes attempting to deliver messages that had suffered
1888 address errors (4xx response to RCPT) over the same connection as other
1889 messages routed to the same hosts. Such deliveries are always "forced",
1890 so retry times are not inspected. This resulted in far too many retries
1891 for the affected addresses. The effect occurred only when there were more
1892 hosts than the hosts_max_try setting in the smtp transport when it had
1893 the 4xx errors. Those hosts that it had tried were not added to the list
1894 of hosts for which the message was waiting, so if all were tried, there
1895 was no problem. Two fixes have been applied:
1896
1897 (i) If there are any address or message errors in an SMTP delivery, none
1898 of the hosts (tried or untried) are now added to the list of hosts
1899 for which the message is waiting, so the message should not be a
1900 candidate for sending over the same connection that was used for a
1901 successful delivery of some other message. This seems entirely
1902 reasonable: after all the message is NOT "waiting for some host".
1903 This is so "obvious" that I'm not sure why it wasn't done
1904 previously. Hope I haven't missed anything, but it can't do any
1905 harm, as the worst effect is to miss an optimization.
1906
1907 (ii) If, despite (i), such a delivery is accidentally attempted, the
1908 routing retry time is respected, so at least it doesn't keep
1909 hammering the server.

1925 written to the panic log as well as the main log, but it isn't really

1927 removed the panic log writing for the ECONNRESET error when getsockname()
1928 fails.

48c7f9e2
PH
1930PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1931 runs only) independently of the message's sender address. This meant
1932 that, if the 4xx error was in fact related to the sender, a different
1933 message to the same recipient with a different sender could confuse
1934 things. In particualar, this can happen when sending to a greylisting
1935 server, but other circumstances could also provoke similar problems.
1936 I have changed the default so that the retry time for these errors is now
1937 based a combination of the sender and recipient addresses. This change
1938 can be overridden by setting address_retry_include_sender=false in the
1939 smtp transport.

2210 tcp-wrappers gives "deny", whereas what one would like would be some
2211 kind of temporary error. A kludge has been added to help with this.
2212 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2213 554 error is used if errno is still zero or contains ENOENT (which occurs
2214 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2300 autoreply, Exim could try to deliver to a non-existent relative file

2337 major problems that occur when a DNS server includes only records of one
2338 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2339 fixed another bug: if SRV records were looked up and the corresponding
2340 address records were *not* found in the additional section, the port
2341 values from the SRV records were lost.

2354 message. Instead it uses the arrival time. This makes for better
2355 behaviour in cases where some deliveries succeed, thus re-setting the
2356 "first failed" field. An example is a quota failure for a huge message
2357 when small messages continue to be delivered. Without this change, the
2358 "time since failure" will always be short, possible causing more frequent
2359 delivery attempts for the huge message than are intended.

PH
2456PH/42 The content-scanning code uses fopen() to create files in which to put
2457 message data. Previously it was not paying any attention to the mode of
2458 the files. Exim runs with umask(0) because the rest of the code creates
2459 files with open(), and sets the required mode explicitly. Thus, these
2460 files were ending up world-writeable. This was not a big issue, because,
2461 being within the spool directory, they were not world-accessible. I have
2462 created a function called modefopen, which takes an additional mode
2463 argument. It sets umask(777), creates the file, chmods it to the required
2464 mode, then resets the umask. All the relevant calls to fopen() in the
2465 content scanning code have been changed to use this function.

2477 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2502
2503 (i) Exim was not creating retry information for temporary errors given
2504 for individual recipients after the DATA command when the smtp transport
2505 was used in LMTP mode. This meant that they could be retried too
2506 frequently, and not timed out correctly.
2507
2508 (ii) Exim was setting the flag that allows error details to be returned
2509 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2510 recipients that were returned after the DATA command.
2511
2512PH/53 This is related to PH/52, but is more general: for any failing address,
2513 when detailed error information was permitted to be returned to the
2514 sender, but the error was temporary, then after the final timeout, only
2515 "retry timeout exceeded" was returned. Now it returns the full error as

2586PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2587 function verify_get_ident() calls ip_connect() to connect a socket, but
2588 if the "connect()" function timed out, ip_connect() used to close the
2589 socket. However, verify_get_ident() also closes the socket later, and in
2590 between Exim writes to the log, which may get opened at this point. When
2591 the socket was closed in ip_connect(), the log could get the same file
2592 descriptor number as the socket. This naturally causes chaos. The fix is
2593 not to close the socket in ip_connect(); the socket should be closed by
2594 the function that creates it. There was only one place in the code where
2595 this was missing, in the iplookup router, which I don't think anybody now
2596 uses, but I've fixed it anyway.

2653 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2654 not being looked up in the rDNS to get a host name, Exim was showing the
2655 IP address twice in Received: lines, even though the IP addresses were
2656 identical. For example:
2657
2658 Received: from [1.2.3.4] (helo=[1.2.3.4])
2659
2660 However, if the real host name was known, it was omitting the HELO data

2754 addresses acquired from the DNS when checking that the found name did
2755 have the original IP as one of its addresses. Since any found IPv6
2756 addresses are likely to be in abbreviated form, the comparison could

3059 preserve the sysexits.h value, by assumimg that macro definitions were

3157PH/18 If the "use_postmaster" option was set for a recipient callout together
3158 with the "random" option, the postmaster address was used as the MAIL
3159 FROM address for the random test, but not for the subsequent recipient
3160 test. It is now used for both.

3162PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3163 patch removes a few documentation additions to RFC 3028, because the
3164 latest draft now contains them. It adds the new en;ascii-case comparator
3165 and a new error check for 8bit text in MIME parts. Comparator and
3166 require names are now matched exactly. I enabled the subaddress
3167 extension, but it is not well tested yet (read: it works for me)."

3169PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3170 rework some of the code of TK/09 above to avoid the hardwired use of
3171 "%lld" and "long long". Replaced the call to snprintf() with a call to
3172 string_vformat().

3178PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3179 experimental DomainKeys support:
3180
3181 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3182 (2) On an error such as an illegally used "control", the wrong name for
3183 the control was given.
3184
3185 These problems did NOT occur unless DomainKeys support was compiled.

PH
3191PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3192 databases so that it will be absolutely obvious if a crash occurs in the
3193 DB library. This is a regular occurrence (often caused by mis-matched
3194 db.h files).
3195
ff790e47 3196PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3197 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3198 picked up on a user's system that detects such things. There doesn't seem
3199 to be a gcc warning option for this - only an attribute that has to be
3200 put on the function's prototype. It seems that in Fedora Core 4 they have
3201 set this on a number of new functions. No doubt there will be more in due
3202 course.

PH
3204PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3205 specify a transport. However, if an address that was verified by such a
3206 router was the subject of a callout, Exim crashed because it tried to
3207 read the rcpt_include_affixes from the non-existent transport. Now it
3208 just assumes that the setting of that option is false. This bug was
3209 introduced by 4.51/PH/31.
3210

PH
3211PH/28 Changed -d+all to exclude +memory, because that information is very
3212 rarely of interest, but it makes the output a lot bigger. People tend to

3215PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the

3217 x86_64 Fedora Core.

3219PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3220 aren't the modern standard, and it seems that some systems' include files
3221 don't always have them. Exim was already checking for some of the newer
3222 ones like T_AAAA, and defining it itself. I've added checks for all the
3223 record types that Exim uses.

PH
3225PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3226 not automatically generating a new one, as it is supposed to. This
3227 prevented TLS from working. If the file did exist, but contained invalid
3228 data, a new version was generated, as expected. It was only the case of a
3229 non-existent file that was broken.

3234TK/11 Domainkeys: Change the logic how the "testing" policy flag is retrieved
3235 from DNS. If the selector record carries the flag, it now has

PH
3240PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3241 the use of a port name that isn't defined in /etc/services) occurred, the
3242 message was deferred as in a normal delivery, and thus remained on the
3243 spool, instead of being failed because of the mua_wrapper setting. This
3244 is now fixed, and I tidied up some of the mua_wrapper messages at the
3245 same time.

3247SC/08 Eximstats: whilst parsing the mainlog(s), store information about
3248 the messages in a hash of arrays rather than using individual hashes.
3249 This is a bit cleaner and results in dramatic memory savings, albeit
3250 at a slight CPU cost.

3274PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3275 to test Sieve filters that use "vacation".
3276
3277PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3278 that changes the way the GnuTLS parameters are stored in the cache file.
3279 The new format can be generated externally. For backward compatibility,
3280 if the data in the cache doesn't make sense, Exim assumes it has read an
3281 old-format file, and it generates new data and writes a new file. This
3282 means that you can't go back to an older release without removing the
3283 file.
3284
3285PH/03 A redirect router that has both "unseen" and "one_time" set does not
3286 work if there are any delivery delays because "one_time" forces the
3287 parent to be marked "delivered", so its unseen clone is never tried
3288 again. For this reason, Exim now forbids the simultaneous setting of
3289 these two options.
3290
3291PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3292 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3293 entry if you want to know the details. The fix, however, neglected to
3294 consider the case when local delivery batching is involved. The test for
3295 "previously delivered" was not happening when checking to see if an
3296 address could be batched with a previous (undelivered) one; under
3297 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3298 address.

PH
3299
3300PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3301 in its include files, and this causes problems building Exim.
3302
3303PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3304 header_syntax) but Exim was just ignoring anything given after a slash.
3305 In particular, this caused confusion with an attempt to use "verify =
3306 reverse_host_lookup/defer_ok". An error is now given when options are
3307 supplied for verify items that do not have them. (Maybe reverse_host_
3308 lookup should have a defer_ok option, but that's a different point.)
3309
3310PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3311 defined by RFC 821) to 2048, because there were problems with some AUTH
3312 commands, and RFC 1869 says the size should be increased for extended
3313 SMTP commands that take arguments.
3314
3315PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3316 Finch).
3317
3318PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an
3319 "unknown" error; now it says that the functionality isn't in the binary.

3346 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3347 negation of where the condition IS allowed.
