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

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.

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.

91-----------------
92
93TF/01 Correctly close the server side of TLS when forking for delivery.
94
95 When a message was received over SMTP with TLS, Exim failed to clear up
96 the incoming connection properly after forking off the child process to
97 deliver the message. In some situations the subsequent outgoing
98 delivery connection happened to have the same fd number as the incoming
99 connection previously had. Exim would try to use TLS and fail, logging
100 a "Bad file descriptor" error.

346TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
347
348 When a queue runner is handling a message, Exim first routes the
349 recipient addresses, during which it prunes them based on the retry
350 hints database. After that it attempts to deliver the message to
351 any remaining recipients. It then updates the hints database using
352 the retry rules.
353
354 So if a recipient address works intermittently, it can get repeatedly
355 deferred at routing time. The retry hints record remains fresh so the
356 address never reaches the final cutoff time.
357
358 This is a fairly common occurrence when a user is bumping up against
359 their storage quota. Exim had some logic in its local delivery code
360 to deal with this. However it did not apply to per-recipient defers
361 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
362
1ddeb334
TF
363 This change adds a proper retry rule check during routing so that the
364 final cutoff time is checked against the message's age. We only do
365 this check if there is an address retry record and there is not a
366 domain retry record; this implies that previous attempts to handle
367 the address had the retry_use_local_parts option turned on. We use
368 this as an approximation for the destination being like a local
369 delivery, as in LMTP.
67bd1ab3
TF
370
371 I suspect this new check makes the old local delivery cutoff check
372 redundant, but I have not verified this so I left the code in place.

377
378 Resent-From: f
379
380 When I ran the test suite under the user fanf2, Exim expanded
381 the header to contain my full name, whereas it should have added
382 a Resent-Sender: header. It erroneously treats any prefix of the
383 username as equal to the username.
384
385 This change corrects that bug.

407 Server implementation by Todd Lyons, client by JH.
408 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
409 config variable "prdr_enable" controls whether the server
410 advertises the facility. If the client requests PRDR a new
411 acl_data_smtp_prdr ACL is called once for each recipient, after
412 the body content is received and before the acl_smtp_data ACL.
413 The client is controlled by bolth of: a hosts_try_prdr option
414 on the smtp transport, and the server advertisement.
415 Default client logging of deliveries and rejections involving
416 PRDR are flagged with the string "PRDR".

426 This is now consistent with GnuTLS, and is now documented: the

429 an empty string is now equivalent.

694TF/03 Make the exiwhat support code safe for signals. Previously Exim might
695 lock up or crash if it happened to be inside a call to libc when it
696 got a SIGUSR1 from exiwhat.
697
698 The SIGUSR1 handler appends the current process status to the process
699 log which is later printed by exiwhat. It used to use the general
700 purpose logging code to do this, but several functions it calls are
701 not safe for signals.
702
703 The new output code in the SIGUSR1 handler is specific to the process
704 log, and simple enough that it's easy to inspect for signal safety.
705 Removing some special cases also simplifies the general logging code.
706 Removing the spurious timestamps from the process log simplifies
707 exiwhat.
708
c99ce5c9
TF
709TF/04 Improved ratelimit ACL condition.
710
711 The /noupdate option has been deprecated in favour of /readonly which
712 has clearer semantics. The /leaky, /strict, and /readonly update modes
713 are mutually exclusive. The update mode is no longer included in the
714 database key; it just determines when the database is updated. (This
715 means that when you upgrde Exim will forget old rate measurements.)
716
717 Exim now checks that the per_* options are used with an update mode that
718 makes sense for the current ACL. For example, when Exim is processing a
719 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
720 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
721 must specify per_mail/readonly. If you omit the update mode it defaults to
722 /leaky where that makes sense (as before) or /readonly where required.
723
724 The /noupdate option is now undocumented but still supported for
725 backwards compatibility. It is equivalent to /readonly except that in
726 ACLs where /readonly is required you may specify /leaky/noupdate or
727 /strict/noupdate which are treated the same as /readonly.
728
729 A useful new feature is the /count= option. This is a generalization
730 of the per_byte option, so that you can measure the throughput of other
731 aggregate values. For example, the per_byte option is now equivalent
732 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
733
734 The per_rcpt option has been generalized using the /count= mechanism
735 (though it's more complicated than the per_byte equivalence). When it is
736 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
737 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
738 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
739 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
740 Note that using per_rcpt with a non-readonly update mode in more than
741 one ACL will cause the recipients to be double-counted. (The per_mail
742 and per_byte options don't have this problem.)
743
744 The handling of very low rates has changed slightly. If the computed rate
745 is less than the event's count (usually one) then this event is the first
746 after a long gap. In this case the rate is set to the same as this event's
747 count, so that the first message of a spam run is counted properly.
748
749 The major new feature is a mechanism for counting the rate of unique
750 events. The new per_addr option counts the number of different
751 recipients that someone has sent messages to in the last time period. It
752 behaves like per_rcpt if all the recipient addresses are different, but
753 duplicate recipient addresses do not increase the measured rate. Like
754 the /count= option this is a general mechanism, so the per_addr option
755 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
756 example, measure the rate that a client uses different sender addresses
757 with the options per_mail/unique=$sender_address. There are further
758 details in the main documentation.

1329
1330PH/01 Another patch from the Sieve maintainer.
1331
6a3bceb1
PH
1332PH/02 When an IPv6 address is converted to a string for single-key lookup
1333 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1334 dots are used instead of colons so that keys in lsearch files need not
1335 contain colons. This was done some time before quoting was made available
1336 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1337 (notated using the quote facility) so as to distinguish them from IPv4
1338 keys. This meant that lookups for IP addresses in host lists did not work
1339 for iplsearch lookups.
1340
1341 This has been fixed by arranging for IPv6 addresses to be expressed with
1342 colons if the lookup type is iplsearch. This is not incompatible, because
1343 previously such lookups could never work.
1344
1345 The situation is now rather anomolous, since one *can* have colons in
1346 ordinary lsearch keys. However, making the change in all cases is
1347 incompatible and would probably break a number of configurations.

MH
1352MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1353 conversion specification without a maximum field width, thereby enabling
1354 a rogue spamd server to cause a buffer overflow. While nobody in their
1355 right mind would setup Exim to query an untrusted spamd server, an
1356 attacker that gains access to a server running spamd could potentially
1357 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1362MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1363 a directory entry by the name of the lookup key. Previously, if a
1364 symlink pointed to a non-existing file or a file in a directory that
1365 Exim lacked permissions to read, a lookup for a key matching that
1366 symlink would fail. Now it is enough that a matching directory entry
1367 exists, symlink or not. (Bugzilla 503.)

1550PH/29 SMTP synchronization checks are implemented when a command is read -
1551 there is a check that no more input is waiting when there shouldn't be

1553 some time before the response is written. In this time, more input might
1554 arrive, invalidly. So now there are extra checks after an ACL has run for
1555 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1556 pipelining has not been advertised.

1571 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1572 was a macro that became an assignment, so it seemed to work. This has

1574 error. Exim's code has been fixed.

1630 the response to the final '.' that terminates a message, but only in the
1631 case where the client has not sent further data following the '.'
1632 (unfortunately, this is allowed). However, in many cases there won't be
1633 any further data because there won't be any more messages to send. A call
1634 to select() can be used: if it shows that the input is "ready", there is
1635 either input waiting, or the socket has been closed. An attempt to read
1636 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1637 would have sent an OK response which the client would never have see.

1647
1648PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1649 fixed by 4.65/MH/01 (is this a record?) are fixed:
1650
1651 (i) An empty string was always treated as zero by the numeric comparison
1652 operators. This behaviour has been restored.
1653
1654 (ii) It is documented that the numeric comparison operators always treat
1655 their arguments as decimal numbers. This was broken in that numbers
1656 starting with 0 were being interpreted as octal.
1657
1658 While fixing these problems I realized that there was another issue that
1659 hadn't been noticed. Values of message_size_limit (both the global option
1660 and the transport option) were treated as octal if they started with 0.
1661 The documentation was vague. These values are now always treated as
1662 decimal, and I will make that clear in the documentation.

1677 child addresses, Exim now panics and dies. Previously, because the count
1678 is held in a short int, deliveries were likely to be lost. As such a
1679 large number of recipients for a single message is ridiculous
1680 (performance will be very, very poor), I have chosen to impose a limit
1681 rather than extend the field.

PH
1706PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1707 callout verification, Exim cached a "reject" for the entire domain. This
1708 is correct for most verifications, but it is not correct for a recipient
1709 verification with use_sender or use_postmaster set, because in that case
1710 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1711 case of MAIL FROM:<> rejection from other early rejections (e.g.
1712 rejection of HELO). When verifying a recipient using a non-null MAIL
1713 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1714 Whatever the result of the callout, the value of the domain cache is
1715 left unchanged (for any other kind of callout, getting as far as trying
1716 RCPT means that the domain itself is ok).

1752 probably the interface on which it is arriving) and not to the outgoing
1753 callout (which could be using a different interface). This has been
1754 changed to use the value of the helo_data option from the smtp transport
1755 instead - this is what is used when a message is actually being sent. If
1756 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
1761 (a) The code assumed that strncpy() returns a negative number on buffer
1762 overflow, which isn't the case. Replaced with Exim's string_format()
1763 function.
1764 (b) There were several signed/unsigned issues. I just did the minimum
1765 hacking in of casts. There is scope for a larger refactoring.
1766 (c) The code used strcasecmp() which is not a standard C function.
1767 Replaced with Exim's strcmpic() function.
1768 (d) The code set only $1; it now sets $auth1 as well.
1769 (e) A simple test gave the error "authentication client didn't specify
1770 service in request". It would seem that Dovecot has changed its
1771 interface. Fortunately there's a specification; I followed it and
1772 changed what the client sends and it appears to be working now.

1778 address A is aliased to B and C, where B exists and C does not. Without
1779 -v the output is "A verified" because verification stops after a
1780 successful redirection if more than one address is generated. However,
1781 with -v the child addresses are also verified. Exim was outputting "A
1782 failed to verify" and then showing the successful verification for C,
1783 with its parentage. It now outputs "B failed to verify", showing B's
1784 parentage before showing the successful verification of C.

PH
1790PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1791 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1792 they consult the DNS. I had assumed they would set it the way they
1793 wanted; and indeed my experiments on Linux seem to show that in some
1794 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1795 To be on the safe side, however, I have now made the interface to
1796 host_find_byname() similar to host_find_bydns(), with an argument
1797 containing the DNS resolver options. The host_find_byname() function now
1798 sets these options at its start, just as host_find_bydns() does. The smtp
1799 transport options dns_qualify_single and dns_search_parents are passed to
1800 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1801 of host_find_byname() use the default settings of RES_DEFNAMES
1802 (qualify_single) but not RES_DNSRCH (search_parents).

1804PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1805 spool_read_header() do less string testing, by means of a preliminary
1806 switch on the second character of optional "-foo" lines. (This is
1807 overdue, caused by the large number of possibilities that now exist.
1808 Originally there were few.) While I was there, I also converted the
1809 str(n)cmp tests so they don't re-test the leading "-" and the first
1810 character, in the hope this might squeeze out yet more improvement.

1812PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1813 flag allowing group syntax was set by the header_syntax check but not
1814 turned off, possible causing trouble later; (2) The flag was not being
1815 set at all for the header_verify test, causing "group"-style headers to
1816 be rejected. I have now set it in this case, and also caused header_
1817 verify to ignore an empty address taken from a group. While doing this, I
1818 came across some other cases where the code for allowing group syntax
1819 while scanning a header line wasn't quite right (mostly, not resetting
1820 the flag correctly in the right place). These bugs could have caused
1821 trouble for malformed header lines. I hope it is now all correct.

PH
1823PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1824 with the "reply" argument non-NULL. The code, however (which originally
1825 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1826 but it didn't always do it. This confused somebody who was copying the
1827 code for some other use. I have removed all the tests.

PH
1829PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1830 feature that was used to support insecure browsers during the U.S. crypto
1831 embargo. It requires special client support, and Exim is probably the
1832 only MTA that supported it -- and would never use it because real RSA is
1833 always available. This code has been removed, because it had the bad
1834 effect of slowing Exim down by computing (never used) parameters for the
1835 RSA_EXPORT functionality.

1840 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1841 if the connection is using TLS or if the remote IP is the same as the
1842 local IP, and the "valid-client-cert option" if a client certificate has
1843 been verified.

1874
1875PH/30 Exim was sometimes attempting to deliver messages that had suffered
1876 address errors (4xx response to RCPT) over the same connection as other
1877 messages routed to the same hosts. Such deliveries are always "forced",
1878 so retry times are not inspected. This resulted in far too many retries
1879 for the affected addresses. The effect occurred only when there were more
1880 hosts than the hosts_max_try setting in the smtp transport when it had
1881 the 4xx errors. Those hosts that it had tried were not added to the list
1882 of hosts for which the message was waiting, so if all were tried, there
1883 was no problem. Two fixes have been applied:
1884
1885 (i) If there are any address or message errors in an SMTP delivery, none
1886 of the hosts (tried or untried) are now added to the list of hosts
1887 for which the message is waiting, so the message should not be a
1888 candidate for sending over the same connection that was used for a
1889 successful delivery of some other message. This seems entirely
1890 reasonable: after all the message is NOT "waiting for some host".
1891 This is so "obvious" that I'm not sure why it wasn't done
1892 previously. Hope I haven't missed anything, but it can't do any
1893 harm, as the worst effect is to miss an optimization.
1894
1895 (ii) If, despite (i), such a delivery is accidentally attempted, the
1896 routing retry time is respected, so at least it doesn't keep
1897 hammering the server.

1912PH/35 The error "getsockname() failed: connection reset by peer" was being
1913 written to the panic log as well as the main log, but it isn't really

1915 removed the panic log writing for the ECONNRESET error when getsockname()
1916 fails.

48c7f9e2
PH
1918PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1919 runs only) independently of the message's sender address. This meant
1920 that, if the 4xx error was in fact related to the sender, a different
1921 message to the same recipient with a different sender could confuse
1922 things. In particualar, this can happen when sending to a greylisting
1923 server, but other circumstances could also provoke similar problems.
1924 I have changed the default so that the retry time for these errors is now
1925 based a combination of the sender and recipient addresses. This change
1926 can be overridden by setting address_retry_include_sender=false in the
1927 smtp transport.

PH
2195PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2196 "Deny" causes Exim to reject the incoming connection with a 554 error.
2197 Unfortunately, if there is a major crisis, such as a disk failure,
2198 tcp-wrappers gives "deny", whereas what one would like would be some
2199 kind of temporary error. A kludge has been added to help with this.
2200 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2201 554 error is used if errno is still zero or contains ENOENT (which occurs
2202 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2203 451 error is used.

2225PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

2228 used only to exclude .Trash (or whatever) when the size of the mailbox

2239PH/01 The code for finding all the local interface addresses on a FreeBSD
2240 system running IPv6 was broken. This may well have applied to all BSD
2241 systems, as well as to others that have similar system calls. The broken
2242 code found IPv4 interfaces correctly, but gave incorrect values for the
2243 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2244 that it would not match correctly against @[] and not recognize the IPv6
2245 addresses as local.

2288 autoreply, Exim could try to deliver to a non-existent relative file
2289 name, causing unrelated and misleading errors. What now happens is that

2308 non-existent - all you got was a failure to exec. I have made two
2309 changes:
2310
2311 (a) Failures to set uid/gid, the current directory, or a process leader
2312 in a subprocess such as that created by queryprogram now generate
2313 suitable debugging ouput when -d is set.
2314
2315 (b) The queryprogram router detects when it is not running as root,
2316 outputs suitable debugging information if -d is set, and then runs
2317 the subprocess without attempting to change uid/gid.

2322PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2323 additional section of a DNS packet that returns MX or SRV records.
2324 Instead, it always explicitly searches for A/AAAA records. This avoids
2325 major problems that occur when a DNS server includes only records of one
2326 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2327 fixed another bug: if SRV records were looked up and the corresponding
2328 address records were *not* found in the additional section, the port
2329 values from the SRV records were lost.

2331PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2335PH/18 If quota_warn_message contains a From: header, Exim now refrains from

2338
727071f8
PH
2339PH/19 When calculating a retry time, Exim used to measure the "time since
2340 failure" by looking at the "first failed" field in the retry record. Now
2341 it does not use this if it is later than than the arrival time of the
2342 message. Instead it uses the arrival time. This makes for better
2343 behaviour in cases where some deliveries succeed, thus re-setting the
2344 "first failed" field. An example is a quota failure for a huge message
2345 when small messages continue to be delivered. Without this change, the
2346 "time since failure" will always be short, possible causing more frequent
2347 delivery attempts for the huge message than are intended.

PH
2444PH/42 The content-scanning code uses fopen() to create files in which to put
2445 message data. Previously it was not paying any attention to the mode of
2446 the files. Exim runs with umask(0) because the rest of the code creates
2447 files with open(), and sets the required mode explicitly. Thus, these
2448 files were ending up world-writeable. This was not a big issue, because,
2449 being within the spool directory, they were not world-accessible. I have
2450 created a function called modefopen, which takes an additional mode
2451 argument. It sets umask(777), creates the file, chmods it to the required
2452 mode, then resets the umask. All the relevant calls to fopen() in the
2453 content scanning code have been changed to use this function.

2465 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2490
2491 (i) Exim was not creating retry information for temporary errors given
2492 for individual recipients after the DATA command when the smtp transport
2493 was used in LMTP mode. This meant that they could be retried too
2494 frequently, and not timed out correctly.
2495
2496 (ii) Exim was setting the flag that allows error details to be returned
2497 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2498 recipients that were returned after the DATA command.
2499
2500PH/53 This is related to PH/52, but is more general: for any failing address,
2501 when detailed error information was permitted to be returned to the
2502 sender, but the error was temporary, then after the final timeout, only
2503 "retry timeout exceeded" was returned. Now it returns the full error as

2574PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2575 function verify_get_ident() calls ip_connect() to connect a socket, but
2576 if the "connect()" function timed out, ip_connect() used to close the
2577 socket. However, verify_get_ident() also closes the socket later, and in
2578 between Exim writes to the log, which may get opened at this point. When
2579 the socket was closed in ip_connect(), the log could get the same file
2580 descriptor number as the socket. This naturally causes chaos. The fix is
2581 not to close the socket in ip_connect(); the socket should be closed by
2582 the function that creates it. There was only one place in the code where
2583 this was missing, in the iplookup router, which I don't think anybody now
2584 uses, but I've fixed it anyway.

2613 because their memory is reclaimed, so using them afterwards may do
2614 silly things.

2641 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2642 not being looked up in the rDNS to get a host name, Exim was showing the
2643 IP address twice in Received: lines, even though the IP addresses were
2644 identical. For example:
2645
2646 Received: from [1.2.3.4] (helo=[1.2.3.4])
2647
2648 However, if the real host name was known, it was omitting the HELO data

2742 addresses acquired from the DNS when checking that the found name did
2743 have the original IP as one of its addresses. Since any found IPv6
2744 addresses are likely to be in abbreviated form, the comparison could
2745 fail. Luckily, there already exists a function for doing the comparison
2746 by converting both addresses to binary, so now that is used instead of
2747 the text comparison.

3046 Fortunately, Exim does not actually use EX_OK. The code used to try to
3047 preserve the sysexits.h value, by assumimg that macro definitions were
3048 scanned for macro replacements. I have been disabused of this notion,

3150PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3151 patch removes a few documentation additions to RFC 3028, because the
3152 latest draft now contains them. It adds the new en;ascii-case comparator
3153 and a new error check for 8bit text in MIME parts. Comparator and
3154 require names are now matched exactly. I enabled the subaddress
3155 extension, but it is not well tested yet (read: it works for me)."

3157PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3158 rework some of the code of TK/09 above to avoid the hardwired use of
3159 "%lld" and "long long". Replaced the call to snprintf() with a call to
3160 string_vformat().

3166PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3167 experimental DomainKeys support:
3168
3169 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3170 (2) On an error such as an illegally used "control", the wrong name for
3171 the control was given.
3172
3173 These problems did NOT occur unless DomainKeys support was compiled.

PH
3179PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3180 databases so that it will be absolutely obvious if a crash occurs in the
3181 DB library. This is a regular occurrence (often caused by mis-matched
3182 db.h files).
3183
ff790e47 3184PH/26 Insert a lot of missing (void) casts for functions such as chown(),

PH
3185 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3186 picked up on a user's system that detects such things. There doesn't seem
3187 to be a gcc warning option for this - only an attribute that has to be
3188 put on the function's prototype. It seems that in Fedora Core 4 they have
3189 set this on a number of new functions. No doubt there will be more in due
3190 course.

PH
3192PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3193 specify a transport. However, if an address that was verified by such a
3194 router was the subject of a callout, Exim crashed because it tried to
3195 read the rcpt_include_affixes from the non-existent transport. Now it
3196 just assumes that the setting of that option is false. This bug was
3197 introduced by 4.51/PH/31.

3199PH/28 Changed -d+all to exclude +memory, because that information is very

3203PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the

3207PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3208 aren't the modern standard, and it seems that some systems' include files
3209 don't always have them. Exim was already checking for some of the newer
3210 ones like T_AAAA, and defining it itself. I've added checks for all the
3211 record types that Exim uses.

PH
3213PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3214 not automatically generating a new one, as it is supposed to. This
3215 prevented TLS from working. If the file did exist, but contained invalid
3216 data, a new version was generated, as expected. It was only the case of a
3217 non-existent file that was broken.

PH
3228PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3229 the use of a port name that isn't defined in /etc/services) occurred, the
3230 message was deferred as in a normal delivery, and thus remained on the
3231 spool, instead of being failed because of the mua_wrapper setting. This
3232 is now fixed, and I tidied up some of the mua_wrapper messages at the
3233 same time.

3235SC/08 Eximstats: whilst parsing the mainlog(s), store information about
3236 the messages in a hash of arrays rather than using individual hashes.
3237 This is a bit cleaner and results in dramatic memory savings, albeit
3238 at a slight CPU cost.

3262PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3263 to test Sieve filters that use "vacation".
3264
3265PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3266 that changes the way the GnuTLS parameters are stored in the cache file.
3267 The new format can be generated externally. For backward compatibility,
3268 if the data in the cache doesn't make sense, Exim assumes it has read an
3269 old-format file, and it generates new data and writes a new file. This
3270 means that you can't go back to an older release without removing the
3271 file.
3272
3273PH/03 A redirect router that has both "unseen" and "one_time" set does not
3274 work if there are any delivery delays because "one_time" forces the
3275 parent to be marked "delivered", so its unseen clone is never tried
3276 again. For this reason, Exim now forbids the simultaneous setting of
3277 these two options.
3278
3279PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3280 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3281 entry if you want to know the details. The fix, however, neglected to
3282 consider the case when local delivery batching is involved. The test for
3283 "previously delivered" was not happening when checking to see if an
3284 address could be batched with a previous (undelivered) one; under
3285 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3286 address.

PH
3287
3288PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3289 in its include files, and this causes problems building Exim.
3290
3291PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3292 header_syntax) but Exim was just ignoring anything given after a slash.
3293 In particular, this caused confusion with an attempt to use "verify =
3294 reverse_host_lookup/defer_ok". An error is now given when options are
3295 supplied for verify items that do not have them. (Maybe reverse_host_
3296 lookup should have a defer_ok option, but that's a different point.)
3297
3298PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3299 defined by RFC 821) to 2048, because there were problems with some AUTH
3300 commands, and RFC 1869 says the size should be increased for extended
3301 SMTP commands that take arguments.
3302
3303PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3304 Finch).
3305
3306PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an

3334 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3335 negation of where the condition IS allowed.

PH
3348PH/19 When an Exim process that is running as root has to create an Exim log
3349 file, it does so in a subprocess that runs as exim:exim so as to get the
3350 ownership right at creation (otherwise, other Exim processes might see
3351 the file with the wrong ownership). There was no test for failure of this
3352 fork() call, which would lead to the process getting stuck as it waited
3353 for a non-existent subprocess. Forks do occasionally fail when resources
3354 run out. I reviewed all the other calls to fork(); they all seem to check
3355 for failure.
