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.

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.

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.

79-----------------
80
81TF/01 Correctly close the server side of TLS when forking for delivery.
82
83 When a message was received over SMTP with TLS, Exim failed to clear up
84 the incoming connection properly after forking off the child process to
85 deliver the message. In some situations the subsequent outgoing
86 delivery connection happened to have the same fd number as the incoming
87 connection previously had. Exim would try to use TLS and fail, logging
88 a "Bad file descriptor" error.

334TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
335
336 When a queue runner is handling a message, Exim first routes the
337 recipient addresses, during which it prunes them based on the retry
338 hints database. After that it attempts to deliver the message to
339 any remaining recipients. It then updates the hints database using
340 the retry rules.
341
342 So if a recipient address works intermittently, it can get repeatedly
343 deferred at routing time. The retry hints record remains fresh so the
344 address never reaches the final cutoff time.
345
346 This is a fairly common occurrence when a user is bumping up against
347 their storage quota. Exim had some logic in its local delivery code
348 to deal with this. However it did not apply to per-recipient defers
349 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
350
1ddeb334
TF
351 This change adds a proper retry rule check during routing so that the
352 final cutoff time is checked against the message's age. We only do
353 this check if there is an address retry record and there is not a
354 domain retry record; this implies that previous attempts to handle
355 the address had the retry_use_local_parts option turned on. We use
356 this as an approximation for the destination being like a local
357 delivery, as in LMTP.
67bd1ab3
TF
358
359 I suspect this new check makes the old local delivery cutoff check
360 redundant, but I have not verified this so I left the code in place.

367
368 When I ran the test suite under the user fanf2, Exim expanded
369 the header to contain my full name, whereas it should have added
370 a Resent-Sender: header. It erroneously treats any prefix of the
371 username as equal to the username.

395 Server implementation by Todd Lyons, client by JH.
396 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
397 config variable "prdr_enable" controls whether the server
398 advertises the facility. If the client requests PRDR a new
399 acl_data_smtp_prdr ACL is called once for each recipient, after
400 the body content is received and before the acl_smtp_data ACL.
401 The client is controlled by bolth of: a hosts_try_prdr option
402 on the smtp transport, and the server advertisement.
403 Default client logging of deliveries and rejections involving
404 PRDR are flagged with the string "PRDR".

682TF/03 Make the exiwhat support code safe for signals. Previously Exim might
683 lock up or crash if it happened to be inside a call to libc when it
684 got a SIGUSR1 from exiwhat.
685
686 The SIGUSR1 handler appends the current process status to the process
687 log which is later printed by exiwhat. It used to use the general
688 purpose logging code to do this, but several functions it calls are
689 not safe for signals.
690
691 The new output code in the SIGUSR1 handler is specific to the process
692 log, and simple enough that it's easy to inspect for signal safety.
693 Removing some special cases also simplifies the general logging code.
694 Removing the spurious timestamps from the process log simplifies
695 exiwhat.
696
c99ce5c9
TF
697TF/04 Improved ratelimit ACL condition.
698
699 The /noupdate option has been deprecated in favour of /readonly which
700 has clearer semantics. The /leaky, /strict, and /readonly update modes
701 are mutually exclusive. The update mode is no longer included in the
702 database key; it just determines when the database is updated. (This
703 means that when you upgrde Exim will forget old rate measurements.)
704
705 Exim now checks that the per_* options are used with an update mode that
706 makes sense for the current ACL. For example, when Exim is processing a
707 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
708 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
709 must specify per_mail/readonly. If you omit the update mode it defaults to
710 /leaky where that makes sense (as before) or /readonly where required.
711
712 The /noupdate option is now undocumented but still supported for
713 backwards compatibility. It is equivalent to /readonly except that in
714 ACLs where /readonly is required you may specify /leaky/noupdate or
715 /strict/noupdate which are treated the same as /readonly.
716
717 A useful new feature is the /count= option. This is a generalization
718 of the per_byte option, so that you can measure the throughput of other
719 aggregate values. For example, the per_byte option is now equivalent
720 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
721
722 The per_rcpt option has been generalized using the /count= mechanism
723 (though it's more complicated than the per_byte equivalence). When it is
724 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
725 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
726 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
727 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
728 Note that using per_rcpt with a non-readonly update mode in more than
729 one ACL will cause the recipients to be double-counted. (The per_mail
730 and per_byte options don't have this problem.)
731
732 The handling of very low rates has changed slightly. If the computed rate
733 is less than the event's count (usually one) then this event is the first
734 after a long gap. In this case the rate is set to the same as this event's
735 count, so that the first message of a spam run is counted properly.
736
737 The major new feature is a mechanism for counting the rate of unique
738 events. The new per_addr option counts the number of different
739 recipients that someone has sent messages to in the last time period. It
740 behaves like per_rcpt if all the recipient addresses are different, but
741 duplicate recipient addresses do not increase the measured rate. Like
742 the /count= option this is a general mechanism, so the per_addr option
743 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
744 example, measure the rate that a client uses different sender addresses
745 with the options per_mail/unique=$sender_address. There are further
746 details in the main documentation.

1296 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1297 were called 'true' and it seems that C99 defines that as a reserved
1298 keyword to be used with 'bool' variable types. That means you could
1299 not include C99-style headers which use bools without triggering

1318PH/01 Another patch from the Sieve maintainer.
1319
6a3bceb1
PH
1320PH/02 When an IPv6 address is converted to a string for single-key lookup
1321 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1322 dots are used instead of colons so that keys in lsearch files need not
1323 contain colons. This was done some time before quoting was made available
1324 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1325 (notated using the quote facility) so as to distinguish them from IPv4
1326 keys. This meant that lookups for IP addresses in host lists did not work
1327 for iplsearch lookups.
1328
1329 This has been fixed by arranging for IPv6 addresses to be expressed with
1330 colons if the lookup type is iplsearch. This is not incompatible, because
1331 previously such lookups could never work.
1332
1333 The situation is now rather anomolous, since one *can* have colons in
1334 ordinary lsearch keys. However, making the change in all cases is
1335 incompatible and would probably break a number of configurations.

MH
1340MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1341 conversion specification without a maximum field width, thereby enabling
1342 a rogue spamd server to cause a buffer overflow. While nobody in their
1343 right mind would setup Exim to query an untrusted spamd server, an
1344 attacker that gains access to a server running spamd could potentially
1345 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1350MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1351 a directory entry by the name of the lookup key. Previously, if a
1352 symlink pointed to a non-existing file or a file in a directory that
1353 Exim lacked permissions to read, a lookup for a key matching that
1354 symlink would fail. Now it is enough that a matching directory entry
1355 exists, symlink or not. (Bugzilla 503.)

1432 if a client was not listed at all, or was listed with a value other than
1433 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

1538PH/29 SMTP synchronization checks are implemented when a command is read -
1539 there is a check that no more input is waiting when there shouldn't be

1541 some time before the response is written. In this time, more input might
1542 arrive, invalidly. So now there are extra checks after an ACL has run for
1543 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1544 pipelining has not been advertised.

1590PH/40 When Exim receives a message, it writes the login name, uid, and gid of

1592 behaving confusingly. When first started, it used values for whoever
1593 started the daemon, but after a SIGHUP it used the Exim user (because it
1594 calls itself on a restart). I have changed the code so that it now always
1595 uses the Exim user.

1597PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

1600 with PIPELINING or a stupid MUA), the error message that was given to the
1601 RCPT commands is included in the rejection of the DATA command. This is
1602 intended to be helpful for MUAs that show only the final error to their

PH
1618 the response to the final '.' that terminates a message, but only in the
1619 case where the client has not sent further data following the '.'
1620 (unfortunately, this is allowed). However, in many cases there won't be
1621 any further data because there won't be any more messages to send. A call
1622 to select() can be used: if it shows that the input is "ready", there is
1623 either input waiting, or the socket has been closed. An attempt to read
1624 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1625 would have sent an OK response which the client would never have see.

1633Exim version 4.66

1635
1636PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1637 fixed by 4.65/MH/01 (is this a record?) are fixed:
1638
1639 (i) An empty string was always treated as zero by the numeric comparison
1640 operators. This behaviour has been restored.
1641
1642 (ii) It is documented that the numeric comparison operators always treat
1643 their arguments as decimal numbers. This was broken in that numbers
1644 starting with 0 were being interpreted as octal.
1645
1646 While fixing these problems I realized that there was another issue that
1647 hadn't been noticed. Values of message_size_limit (both the global option
1648 and the transport option) were treated as octal if they started with 0.
1649 The documentation was vague. These values are now always treated as
1650 decimal, and I will make that clear in the documentation.

1664PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1665 child addresses, Exim now panics and dies. Previously, because the count
1666 is held in a short int, deliveries were likely to be lost. As such a
1667 large number of recipients for a single message is ridiculous
1668 (performance will be very, very poor), I have chosen to impose a limit
1669 rather than extend the field.

PH
1694PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1695 callout verification, Exim cached a "reject" for the entire domain. This
1696 is correct for most verifications, but it is not correct for a recipient
1697 verification with use_sender or use_postmaster set, because in that case
1698 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1699 case of MAIL FROM:<> rejection from other early rejections (e.g.
1700 rejection of HELO). When verifying a recipient using a non-null MAIL
1701 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1702 Whatever the result of the callout, the value of the domain cache is
1703 left unchanged (for any other kind of callout, getting as far as trying
1704 RCPT means that the domain itself is ok).

1740 probably the interface on which it is arriving) and not to the outgoing
1741 callout (which could be using a different interface). This has been
1742 changed to use the value of the helo_data option from the smtp transport
1743 instead - this is what is used when a message is actually being sent. If
1744 there is no remote transport (possible with a router that sets up host
1745 addresses), $smtp_active_hostname is used.

14aa5a05
PH
1749 (a) The code assumed that strncpy() returns a negative number on buffer
1750 overflow, which isn't the case. Replaced with Exim's string_format()
1751 function.
1752 (b) There were several signed/unsigned issues. I just did the minimum
1753 hacking in of casts. There is scope for a larger refactoring.
1754 (c) The code used strcasecmp() which is not a standard C function.
1755 Replaced with Exim's strcmpic() function.
1756 (d) The code set only $1; it now sets $auth1 as well.
1757 (e) A simple test gave the error "authentication client didn't specify
1758 service in request". It would seem that Dovecot has changed its
1759 interface. Fortunately there's a specification; I followed it and
1760 changed what the client sends and it appears to be working now.

1766 address A is aliased to B and C, where B exists and C does not. Without
1767 -v the output is "A verified" because verification stops after a
1768 successful redirection if more than one address is generated. However,
1769 with -v the child addresses are also verified. Exim was outputting "A
1770 failed to verify" and then showing the successful verification for C,
1771 with its parentage. It now outputs "B failed to verify", showing B's
1772 parentage before showing the successful verification of C.

322050c2
PH
1778PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1779 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1780 they consult the DNS. I had assumed they would set it the way they
1781 wanted; and indeed my experiments on Linux seem to show that in some
1782 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1783 To be on the safe side, however, I have now made the interface to
1784 host_find_byname() similar to host_find_bydns(), with an argument
1785 containing the DNS resolver options. The host_find_byname() function now
1786 sets these options at its start, just as host_find_bydns() does. The smtp
1787 transport options dns_qualify_single and dns_search_parents are passed to
1788 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1789 of host_find_byname() use the default settings of RES_DEFNAMES
1790 (qualify_single) but not RES_DNSRCH (search_parents).

1793 spool_read_header() do less string testing, by means of a preliminary
1794 switch on the second character of optional "-foo" lines. (This is
1795 overdue, caused by the large number of possibilities that now exist.
1796 Originally there were few.) While I was there, I also converted the
1797 str(n)cmp tests so they don't re-test the leading "-" and the first
1798 character, in the hope this might squeeze out yet more improvement.

1800PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1801 flag allowing group syntax was set by the header_syntax check but not
1802 turned off, possible causing trouble later; (2) The flag was not being
1803 set at all for the header_verify test, causing "group"-style headers to
1804 be rejected. I have now set it in this case, and also caused header_
1805 verify to ignore an empty address taken from a group. While doing this, I
1806 came across some other cases where the code for allowing group syntax
1807 while scanning a header line wasn't quite right (mostly, not resetting
1808 the flag correctly in the right place). These bugs could have caused
1809 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1811PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1812 with the "reply" argument non-NULL. The code, however (which originally
1813 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1814 but it didn't always do it. This confused somebody who was copying the
1815 code for some other use. I have removed all the tests.

PH
1817PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1818 feature that was used to support insecure browsers during the U.S. crypto
1819 embargo. It requires special client support, and Exim is probably the
1820 only MTA that supported it -- and would never use it because real RSA is
1821 always available. This code has been removed, because it had the bad
1822 effect of slowing Exim down by computing (never used) parameters for the
1823 RSA_EXPORT functionality.

1826 authenticator to fail if there's a tab character in the incoming data

1828 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1829 if the connection is using TLS or if the remote IP is the same as the
1830 local IP, and the "valid-client-cert option" if a client certificate has
1831 been verified.

1862
1863PH/30 Exim was sometimes attempting to deliver messages that had suffered
1864 address errors (4xx response to RCPT) over the same connection as other
1865 messages routed to the same hosts. Such deliveries are always "forced",
1866 so retry times are not inspected. This resulted in far too many retries
1867 for the affected addresses. The effect occurred only when there were more
1868 hosts than the hosts_max_try setting in the smtp transport when it had
1869 the 4xx errors. Those hosts that it had tried were not added to the list
1870 of hosts for which the message was waiting, so if all were tried, there
1871 was no problem. Two fixes have been applied:
1872
1873 (i) If there are any address or message errors in an SMTP delivery, none
1874 of the hosts (tried or untried) are now added to the list of hosts
1875 for which the message is waiting, so the message should not be a
1876 candidate for sending over the same connection that was used for a
1877 successful delivery of some other message. This seems entirely
1878 reasonable: after all the message is NOT "waiting for some host".
1879 This is so "obvious" that I'm not sure why it wasn't done
1880 previously. Hope I haven't missed anything, but it can't do any
1881 harm, as the worst effect is to miss an optimization.
1882
1883 (ii) If, despite (i), such a delivery is accidentally attempted, the
1884 routing retry time is respected, so at least it doesn't keep
1885 hammering the server.

1900PH/35 The error "getsockname() failed: connection reset by peer" was being
1901 written to the panic log as well as the main log, but it isn't really

1903 removed the panic log writing for the ECONNRESET error when getsockname()
1904 fails.
1905
48c7f9e2
PH
1906PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1907 runs only) independently of the message's sender address. This meant
1908 that, if the 4xx error was in fact related to the sender, a different
1909 message to the same recipient with a different sender could confuse
1910 things. In particualar, this can happen when sending to a greylisting
1911 server, but other circumstances could also provoke similar problems.
1912 I have changed the default so that the retry time for these errors is now
1913 based a combination of the sender and recipient addresses. This change
1914 can be overridden by setting address_retry_include_sender=false in the
1915 smtp transport.

2183PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2185 Unfortunately, if there is a major crisis, such as a disk failure,
2186 tcp-wrappers gives "deny", whereas what one would like would be some
2187 kind of temporary error. A kludge has been added to help with this.
2188 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2189 554 error is used if errno is still zero or contains ENOENT (which occurs
2190 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2191 451 error is used.

2230 code found IPv4 interfaces correctly, but gave incorrect values for the
2231 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2232 that it would not match correctly against @[] and not recognize the IPv6
2233 addresses as local.

2276 autoreply, Exim could try to deliver to a non-existent relative file

2300 in a subprocess such as that created by queryprogram now generate
2301 suitable debugging ouput when -d is set.

2312 Instead, it always explicitly searches for A/AAAA records. This avoids
2313 major problems that occur when a DNS server includes only records of one
2314 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2315 fixed another bug: if SRV records were looked up and the corresponding
2316 address records were *not* found in the additional section, the port
2317 values from the SRV records were lost.

2327PH/19 When calculating a retry time, Exim used to measure the "time since
2328 failure" by looking at the "first failed" field in the retry record. Now
2329 it does not use this if it is later than than the arrival time of the
2330 message. Instead it uses the arrival time. This makes for better
2331 behaviour in cases where some deliveries succeed, thus re-setting the
2332 "first failed" field. An example is a quota failure for a huge message
2333 when small messages continue to be delivered. Without this change, the
2334 "time since failure" will always be short, possible causing more frequent
2335 delivery attempts for the huge message than are intended.

PH
2432PH/42 The content-scanning code uses fopen() to create files in which to put
2433 message data. Previously it was not paying any attention to the mode of
2434 the files. Exim runs with umask(0) because the rest of the code creates
2435 files with open(), and sets the required mode explicitly. Thus, these
2436 files were ending up world-writeable. This was not a big issue, because,
2437 being within the spool directory, they were not world-accessible. I have
2438 created a function called modefopen, which takes an additional mode
2439 argument. It sets umask(777), creates the file, chmods it to the required
2440 mode, then resets the umask. All the relevant calls to fopen() in the
2441 content scanning code have been changed to use this function.

2453 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2476PH/52 Two bugs concerned with error handling when the smtp transport is
2477 used in LMTP mode:
2478
2479 (i) Exim was not creating retry information for temporary errors given
2480 for individual recipients after the DATA command when the smtp transport
2481 was used in LMTP mode. This meant that they could be retried too
2482 frequently, and not timed out correctly.
2483
2484 (ii) Exim was setting the flag that allows error details to be returned
2485 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2486 recipients that were returned after the DATA command.
2487
2488PH/53 This is related to PH/52, but is more general: for any failing address,
2489 when detailed error information was permitted to be returned to the
2490 sender, but the error was temporary, then after the final timeout, only
2491 "retry timeout exceeded" was returned. Now it returns the full error as

2562PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2563 function verify_get_ident() calls ip_connect() to connect a socket, but
2564 if the "connect()" function timed out, ip_connect() used to close the
2565 socket. However, verify_get_ident() also closes the socket later, and in
2566 between Exim writes to the log, which may get opened at this point. When
2567 the socket was closed in ip_connect(), the log could get the same file
2568 descriptor number as the socket. This naturally causes chaos. The fix is
2569 not to close the socket in ip_connect(); the socket should be closed by
2570 the function that creates it. There was only one place in the code where
2571 this was missing, in the iplookup router, which I don't think anybody now
2572 uses, but I've fixed it anyway.

2599 (3) Reset the variables that are obtained from the first argument of
2600 ${prvscheck and used in the second argument before leaving the code,
2601 because their memory is reclaimed, so using them afterwards may do
2602 silly things.

2629 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2630 not being looked up in the rDNS to get a host name, Exim was showing the
2631 IP address twice in Received: lines, even though the IP addresses were
2632 identical. For example:
2633
2634 Received: from [1.2.3.4] (helo=[1.2.3.4])
2635
2636 However, if the real host name was known, it was omitting the HELO data

2730 addresses acquired from the DNS when checking that the found name did
2731 have the original IP as one of its addresses. Since any found IPv6
2732 addresses are likely to be in abbreviated form, the comparison could
2733 fail. Luckily, there already exists a function for doing the comparison
2734 by converting both addresses to binary, so now that is used instead of

3034 Fortunately, Exim does not actually use EX_OK. The code used to try to
3035 preserve the sysexits.h value, by assumimg that macro definitions were
3036 scanned for macro replacements. I have been disabused of this notion,

3043 would take for ever. The timeout is now adjusted when this happens. It
3044 doesn't have to be particularly precise.

3154PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3155 experimental DomainKeys support:
3156
3157 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3158 (2) On an error such as an illegally used "control", the wrong name for
3159 the control was given.

3161 These problems did NOT occur unless DomainKeys support was compiled.

3167PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3168 databases so that it will be absolutely obvious if a crash occurs in the

3170 db.h files).

3173 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3174 picked up on a user's system that detects such things. There doesn't seem
3175 to be a gcc warning option for this - only an attribute that has to be
3176 put on the function's prototype. It seems that in Fedora Core 4 they have
3177 set this on a number of new functions. No doubt there will be more in due
3178 course.

3180PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3181 specify a transport. However, if an address that was verified by such a
3182 router was the subject of a callout, Exim crashed because it tried to
3183 read the rcpt_include_affixes from the non-existent transport. Now it
3184 just assumes that the setting of that option is false. This bug was
3185 introduced by 4.51/PH/31.

3195PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3196 aren't the modern standard, and it seems that some systems' include files
3197 don't always have them. Exim was already checking for some of the newer
3198 ones like T_AAAA, and defining it itself. I've added checks for all the
3199 record types that Exim uses.

3201PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3202 not automatically generating a new one, as it is supposed to. This
3203 prevented TLS from working. If the file did exist, but contained invalid
3204 data, a new version was generated, as expected. It was only the case of a
3205 non-existent file that was broken.

3216PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3217 the use of a port name that isn't defined in /etc/services) occurred, the
3218 message was deferred as in a normal delivery, and thus remained on the
3219 spool, instead of being failed because of the mua_wrapper setting. This
3220 is now fixed, and I tidied up some of the mua_wrapper messages at the
3221 same time.

3223SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3250PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3251 to test Sieve filters that use "vacation".
3252
3253PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3254 that changes the way the GnuTLS parameters are stored in the cache file.
3255 The new format can be generated externally. For backward compatibility,
3256 if the data in the cache doesn't make sense, Exim assumes it has read an
3257 old-format file, and it generates new data and writes a new file. This
3258 means that you can't go back to an older release without removing the
3259 file.
3260
3261PH/03 A redirect router that has both "unseen" and "one_time" set does not
3262 work if there are any delivery delays because "one_time" forces the
3263 parent to be marked "delivered", so its unseen clone is never tried
3264 again. For this reason, Exim now forbids the simultaneous setting of
3265 these two options.
3266
3267PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3268 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3269 entry if you want to know the details. The fix, however, neglected to
3270 consider the case when local delivery batching is involved. The test for
3271 "previously delivered" was not happening when checking to see if an
3272 address could be batched with a previous (undelivered) one; under
3273 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3274 address.
1a46a8c5
PH
3275
3276PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3277 in its include files, and this causes problems building Exim.
3278
3279PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3280 header_syntax) but Exim was just ignoring anything given after a slash.
3281 In particular, this caused confusion with an attempt to use "verify =
3282 reverse_host_lookup/defer_ok". An error is now given when options are
3283 supplied for verify items that do not have them. (Maybe reverse_host_
3284 lookup should have a defer_ok option, but that's a different point.)
3285
3286PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3287 defined by RFC 821) to 2048, because there were problems with some AUTH
3288 commands, and RFC 1869 says the size should be increased for extended
3289 SMTP commands that take arguments.
3290

3292 Finch).

3322 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3323 negation of where the condition IS allowed.

PH
3336PH/19 When an Exim process that is running as root has to create an Exim log
3337 file, it does so in a subprocess that runs as exim:exim so as to get the
3338 ownership right at creation (otherwise, other Exim processes might see
3339 the file with the wrong ownership). There was no test for failure of this
3340 fork() call, which would lead to the process getting stuck as it waited
3341 for a non-existent subprocess. Forks do occasionally fail when resources
3342 run out. I reviewed all the other calls to fork(); they all seem to check
3343 for failure.

PH
3345PH/20 When checking for unexpected SMTP input at connect time (before writing
3346 the banner), Exim was not dealing correctly with a non-positive return
3347 from the read() function. If the client had disconnected by this time,
3348 the result was a log entry for a synchronization error with an empty
3349 string after "input=" when read() returned zero. If read() returned -1
3350 (an event I could not check), uninitialized data bytes were printed.
3351 There were reports of junk text (parts of files, etc) appearing after
3352 "input=".
