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.

16 adding randomness was arc4random_stir(), but it has been removed in

18 function when detected.

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.

71-----------------
72
73TF/01 Correctly close the server side of TLS when forking for delivery.
74
75 When a message was received over SMTP with TLS, Exim failed to clear up
76 the incoming connection properly after forking off the child process to
77 deliver the message. In some situations the subsequent outgoing
78 delivery connection happened to have the same fd number as the incoming
79 connection previously had. Exim would try to use TLS and fail, logging
80 a "Bad file descriptor" error.

TF
326TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
327
328 When a queue runner is handling a message, Exim first routes the
329 recipient addresses, during which it prunes them based on the retry
330 hints database. After that it attempts to deliver the message to
331 any remaining recipients. It then updates the hints database using
332 the retry rules.
333
334 So if a recipient address works intermittently, it can get repeatedly
335 deferred at routing time. The retry hints record remains fresh so the
336 address never reaches the final cutoff time.
337
338 This is a fairly common occurrence when a user is bumping up against
339 their storage quota. Exim had some logic in its local delivery code
340 to deal with this. However it did not apply to per-recipient defers
341 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
342
1ddeb334
TF
343 This change adds a proper retry rule check during routing so that the
344 final cutoff time is checked against the message's age. We only do
345 this check if there is an address retry record and there is not a
346 domain retry record; this implies that previous attempts to handle
347 the address had the retry_use_local_parts option turned on. We use
348 this as an approximation for the destination being like a local
349 delivery, as in LMTP.
67bd1ab3
TF
350
351 I suspect this new check makes the old local delivery cutoff check
352 redundant, but I have not verified this so I left the code in place.

359
360 When I ran the test suite under the user fanf2, Exim expanded
361 the header to contain my full name, whereas it should have added
362 a Resent-Sender: header. It erroneously treats any prefix of the
363 username as equal to the username.

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

674TF/03 Make the exiwhat support code safe for signals. Previously Exim might
675 lock up or crash if it happened to be inside a call to libc when it
676 got a SIGUSR1 from exiwhat.
677
678 The SIGUSR1 handler appends the current process status to the process
679 log which is later printed by exiwhat. It used to use the general
680 purpose logging code to do this, but several functions it calls are
681 not safe for signals.
682
683 The new output code in the SIGUSR1 handler is specific to the process
684 log, and simple enough that it's easy to inspect for signal safety.
685 Removing some special cases also simplifies the general logging code.
686 Removing the spurious timestamps from the process log simplifies
687 exiwhat.
688
c99ce5c9
TF
689TF/04 Improved ratelimit ACL condition.
690
691 The /noupdate option has been deprecated in favour of /readonly which
692 has clearer semantics. The /leaky, /strict, and /readonly update modes
693 are mutually exclusive. The update mode is no longer included in the
694 database key; it just determines when the database is updated. (This
695 means that when you upgrde Exim will forget old rate measurements.)
696
697 Exim now checks that the per_* options are used with an update mode that
698 makes sense for the current ACL. For example, when Exim is processing a
699 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
700 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
701 must specify per_mail/readonly. If you omit the update mode it defaults to
702 /leaky where that makes sense (as before) or /readonly where required.
703
704 The /noupdate option is now undocumented but still supported for
705 backwards compatibility. It is equivalent to /readonly except that in
706 ACLs where /readonly is required you may specify /leaky/noupdate or
707 /strict/noupdate which are treated the same as /readonly.
708
709 A useful new feature is the /count= option. This is a generalization
710 of the per_byte option, so that you can measure the throughput of other
711 aggregate values. For example, the per_byte option is now equivalent
712 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
713
714 The per_rcpt option has been generalized using the /count= mechanism
715 (though it's more complicated than the per_byte equivalence). When it is
716 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
717 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
718 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
719 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
720 Note that using per_rcpt with a non-readonly update mode in more than
721 one ACL will cause the recipients to be double-counted. (The per_mail
722 and per_byte options don't have this problem.)
723
724 The handling of very low rates has changed slightly. If the computed rate
725 is less than the event's count (usually one) then this event is the first
726 after a long gap. In this case the rate is set to the same as this event's
727 count, so that the first message of a spam run is counted properly.
728
729 The major new feature is a mechanism for counting the rate of unique
730 events. The new per_addr option counts the number of different
731 recipients that someone has sent messages to in the last time period. It
732 behaves like per_rcpt if all the recipient addresses are different, but
733 duplicate recipient addresses do not increase the measured rate. Like
734 the /count= option this is a general mechanism, so the per_addr option
735 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
736 example, measure the rate that a client uses different sender addresses
737 with the options per_mail/unique=$sender_address. There are further
738 details in the main documentation.

820 cause arbitrary Exim lookups (of items which can occur in lists, *not*
821 arbitrary string expansion). This allowed for information disclosure.

1288 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1289 were called 'true' and it seems that C99 defines that as a reserved

1291 not include C99-style headers which use bools without triggering

1308-----------------
1309
1310PH/01 Another patch from the Sieve maintainer.
1311
6a3bceb1
PH
1312PH/02 When an IPv6 address is converted to a string for single-key lookup
1313 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1314 dots are used instead of colons so that keys in lsearch files need not
1315 contain colons. This was done some time before quoting was made available
1316 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1317 (notated using the quote facility) so as to distinguish them from IPv4
1318 keys. This meant that lookups for IP addresses in host lists did not work
1319 for iplsearch lookups.
1320
1321 This has been fixed by arranging for IPv6 addresses to be expressed with
1322 colons if the lookup type is iplsearch. This is not incompatible, because
1323 previously such lookups could never work.
1324
1325 The situation is now rather anomolous, since one *can* have colons in
1326 ordinary lsearch keys. However, making the change in all cases is
1327 incompatible and would probably break a number of configurations.

MH
1332MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1333 conversion specification without a maximum field width, thereby enabling
1334 a rogue spamd server to cause a buffer overflow. While nobody in their
1335 right mind would setup Exim to query an untrusted spamd server, an
1336 attacker that gains access to a server running spamd could potentially
1337 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1342MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1343 a directory entry by the name of the lookup key. Previously, if a
1344 symlink pointed to a non-existing file or a file in a directory that
1345 Exim lacked permissions to read, a lookup for a key matching that
1346 symlink would fail. Now it is enough that a matching directory entry
1347 exists, symlink or not. (Bugzilla 503.)

1424 if a client was not listed at all, or was listed with a value other than
1425 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

1530PH/29 SMTP synchronization checks are implemented when a command is read -
1531 there is a check that no more input is waiting when there shouldn't be
1532 any. However, for some commands, a delay in an ACL can mean that it is
1533 some time before the response is written. In this time, more input might
1534 arrive, invalidly. So now there are extra checks after an ACL has run for
1535 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1536 pipelining has not been advertised.

1551 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1552 was a macro that became an assignment, so it seemed to work. This has

1582PH/40 When Exim receives a message, it writes the login name, uid, and gid of

1584 behaving confusingly. When first started, it used values for whoever
1585 started the daemon, but after a SIGHUP it used the Exim user (because it
1586 calls itself on a restart). I have changed the code so that it now always
1587 uses the Exim user.

1589PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

1591 sender address), and a DATA command is nevertheless sent (as can happen
1592 with PIPELINING or a stupid MUA), the error message that was given to the
1593 RCPT commands is included in the rejection of the DATA command. This is
1594 intended to be helpful for MUAs that show only the final error to their
1595 users.

PH
1610 the response to the final '.' that terminates a message, but only in the
1611 case where the client has not sent further data following the '.'
1612 (unfortunately, this is allowed). However, in many cases there won't be
1613 any further data because there won't be any more messages to send. A call
1614 to select() can be used: if it shows that the input is "ready", there is
1615 either input waiting, or the socket has been closed. An attempt to read
1616 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1617 would have sent an OK response which the client would never have see.

1625Exim version 4.66
1626-----------------
1627
1628PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1629 fixed by 4.65/MH/01 (is this a record?) are fixed:
1630
1631 (i) An empty string was always treated as zero by the numeric comparison
1632 operators. This behaviour has been restored.
1633
1634 (ii) It is documented that the numeric comparison operators always treat
1635 their arguments as decimal numbers. This was broken in that numbers
1636 starting with 0 were being interpreted as octal.
1637
1638 While fixing these problems I realized that there was another issue that
1639 hadn't been noticed. Values of message_size_limit (both the global option
1640 and the transport option) were treated as octal if they started with 0.
1641 The documentation was vague. These values are now always treated as
1642 decimal, and I will make that clear in the documentation.

1656PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1657 child addresses, Exim now panics and dies. Previously, because the count
1658 is held in a short int, deliveries were likely to be lost. As such a
1659 large number of recipients for a single message is ridiculous
1660 (performance will be very, very poor), I have chosen to impose a limit
1661 rather than extend the field.

1677TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
1686PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1687 callout verification, Exim cached a "reject" for the entire domain. This
1688 is correct for most verifications, but it is not correct for a recipient
1689 verification with use_sender or use_postmaster set, because in that case
1690 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1691 case of MAIL FROM:<> rejection from other early rejections (e.g.
1692 rejection of HELO). When verifying a recipient using a non-null MAIL
1693 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1694 Whatever the result of the callout, the value of the domain cache is
1695 left unchanged (for any other kind of callout, getting as far as trying
1696 RCPT means that the domain itself is ok).

1730PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1732 probably the interface on which it is arriving) and not to the outgoing
1733 callout (which could be using a different interface). This has been
1734 changed to use the value of the helo_data option from the smtp transport
1735 instead - this is what is used when a message is actually being sent. If
1736 there is no remote transport (possible with a router that sets up host
1737 addresses), $smtp_active_hostname is used.

7befa435 1740 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1741 (a) The code assumed that strncpy() returns a negative number on buffer
1742 overflow, which isn't the case. Replaced with Exim's string_format()
1743 function.
1744 (b) There were several signed/unsigned issues. I just did the minimum
1745 hacking in of casts. There is scope for a larger refactoring.
1746 (c) The code used strcasecmp() which is not a standard C function.
1747 Replaced with Exim's strcmpic() function.
1748 (d) The code set only $1; it now sets $auth1 as well.
1749 (e) A simple test gave the error "authentication client didn't specify
1750 service in request". It would seem that Dovecot has changed its
1751 interface. Fortunately there's a specification; I followed it and
1752 changed what the client sends and it appears to be working now.

1758 address A is aliased to B and C, where B exists and C does not. Without
1759 -v the output is "A verified" because verification stops after a
1760 successful redirection if more than one address is generated. However,
1761 with -v the child addresses are also verified. Exim was outputting "A
1762 failed to verify" and then showing the successful verification for C,
1763 with its parentage. It now outputs "B failed to verify", showing B's
1764 parentage before showing the successful verification of C.

PH
1770PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1771 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1772 they consult the DNS. I had assumed they would set it the way they
1773 wanted; and indeed my experiments on Linux seem to show that in some
1774 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1775 To be on the safe side, however, I have now made the interface to
1776 host_find_byname() similar to host_find_bydns(), with an argument
1777 containing the DNS resolver options. The host_find_byname() function now
1778 sets these options at its start, just as host_find_bydns() does. The smtp
1779 transport options dns_qualify_single and dns_search_parents are passed to
1780 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1781 of host_find_byname() use the default settings of RES_DEFNAMES
1782 (qualify_single) but not RES_DNSRCH (search_parents).

1784PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1785 spool_read_header() do less string testing, by means of a preliminary
1786 switch on the second character of optional "-foo" lines. (This is
1787 overdue, caused by the large number of possibilities that now exist.
1788 Originally there were few.) While I was there, I also converted the
1789 str(n)cmp tests so they don't re-test the leading "-" and the first
1790 character, in the hope this might squeeze out yet more improvement.

1792PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1793 flag allowing group syntax was set by the header_syntax check but not
1794 turned off, possible causing trouble later; (2) The flag was not being
1795 set at all for the header_verify test, causing "group"-style headers to
1796 be rejected. I have now set it in this case, and also caused header_
1797 verify to ignore an empty address taken from a group. While doing this, I
1798 came across some other cases where the code for allowing group syntax
1799 while scanning a header line wasn't quite right (mostly, not resetting
1800 the flag correctly in the right place). These bugs could have caused
1801 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1803PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1804 with the "reply" argument non-NULL. The code, however (which originally
1805 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1806 but it didn't always do it. This confused somebody who was copying the
1807 code for some other use. I have removed all the tests.

PH
1809PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1810 feature that was used to support insecure browsers during the U.S. crypto
1811 embargo. It requires special client support, and Exim is probably the
1812 only MTA that supported it -- and would never use it because real RSA is
1813 always available. This code has been removed, because it had the bad
1814 effect of slowing Exim down by computing (never used) parameters for the
1815 RSA_EXPORT functionality.

PH
1817PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1818 authenticator to fail if there's a tab character in the incoming data
1819 (there should never be unless someone is messing about, as it's supposed
1820 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1821 if the connection is using TLS or if the remote IP is the same as the
1822 local IP, and the "valid-client-cert option" if a client certificate has
1823 been verified.

1854
1855PH/30 Exim was sometimes attempting to deliver messages that had suffered
1856 address errors (4xx response to RCPT) over the same connection as other
1857 messages routed to the same hosts. Such deliveries are always "forced",
1858 so retry times are not inspected. This resulted in far too many retries
1859 for the affected addresses. The effect occurred only when there were more
1860 hosts than the hosts_max_try setting in the smtp transport when it had
1861 the 4xx errors. Those hosts that it had tried were not added to the list
1862 of hosts for which the message was waiting, so if all were tried, there
1863 was no problem. Two fixes have been applied:
1864
1865 (i) If there are any address or message errors in an SMTP delivery, none
1866 of the hosts (tried or untried) are now added to the list of hosts
1867 for which the message is waiting, so the message should not be a
1868 candidate for sending over the same connection that was used for a
1869 successful delivery of some other message. This seems entirely
1870 reasonable: after all the message is NOT "waiting for some host".
1871 This is so "obvious" that I'm not sure why it wasn't done
1872 previously. Hope I haven't missed anything, but it can't do any
1873 harm, as the worst effect is to miss an optimization.
1874
1875 (ii) If, despite (i), such a delivery is accidentally attempted, the
1876 routing retry time is respected, so at least it doesn't keep
1877 hammering the server.

1892PH/35 The error "getsockname() failed: connection reset by peer" was being
1893 written to the panic log as well as the main log, but it isn't really

1895 removed the panic log writing for the ECONNRESET error when getsockname()
1896 fails.
1897
48c7f9e2
PH
1898PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1899 runs only) independently of the message's sender address. This meant
1900 that, if the 4xx error was in fact related to the sender, a different
1901 message to the same recipient with a different sender could confuse
1902 things. In particualar, this can happen when sending to a greylisting
1903 server, but other circumstances could also provoke similar problems.
1904 I have changed the default so that the retry time for these errors is now
1905 based a combination of the sender and recipient addresses. This change
1906 can be overridden by setting address_retry_include_sender=false in the
1907 smtp transport.

2175PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2177 Unfortunately, if there is a major crisis, such as a disk failure,
2178 tcp-wrappers gives "deny", whereas what one would like would be some
2179 kind of temporary error. A kludge has been added to help with this.
2180 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2181 554 error is used if errno is still zero or contains ENOENT (which occurs
2182 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2183 451 error is used.

2222 code found IPv4 interfaces correctly, but gave incorrect values for the
2223 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2268 autoreply, Exim could try to deliver to a non-existent relative file

2292 in a subprocess such as that created by queryprogram now generate
2293 suitable debugging ouput when -d is set.

2303 additional section of a DNS packet that returns MX or SRV records.
2304 Instead, it always explicitly searches for A/AAAA records. This avoids
2305 major problems that occur when a DNS server includes only records of one
2306 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2307 fixed another bug: if SRV records were looked up and the corresponding
2308 address records were *not* found in the additional section, the port
2309 values from the SRV records were lost.

2311PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2319PH/19 When calculating a retry time, Exim used to measure the "time since
2320 failure" by looking at the "first failed" field in the retry record. Now
2321 it does not use this if it is later than than the arrival time of the
2322 message. Instead it uses the arrival time. This makes for better
2323 behaviour in cases where some deliveries succeed, thus re-setting the
2324 "first failed" field. An example is a quota failure for a huge message
2325 when small messages continue to be delivered. Without this change, the
2326 "time since failure" will always be short, possible causing more frequent
2327 delivery attempts for the huge message than are intended.

PH
2424PH/42 The content-scanning code uses fopen() to create files in which to put
2425 message data. Previously it was not paying any attention to the mode of
2426 the files. Exim runs with umask(0) because the rest of the code creates
2427 files with open(), and sets the required mode explicitly. Thus, these
2428 files were ending up world-writeable. This was not a big issue, because,
2429 being within the spool directory, they were not world-accessible. I have
2430 created a function called modefopen, which takes an additional mode
2431 argument. It sets umask(777), creates the file, chmods it to the required
2432 mode, then resets the umask. All the relevant calls to fopen() in the
2433 content scanning code have been changed to use this function.

2470
2471 (i) Exim was not creating retry information for temporary errors given
2472 for individual recipients after the DATA command when the smtp transport
2473 was used in LMTP mode. This meant that they could be retried too
2474 frequently, and not timed out correctly.
2475
2476 (ii) Exim was setting the flag that allows error details to be returned
2477 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2478 recipients that were returned after the DATA command.
2479
2480PH/53 This is related to PH/52, but is more general: for any failing address,
2481 when detailed error information was permitted to be returned to the
2482 sender, but the error was temporary, then after the final timeout, only

2554PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2555 function verify_get_ident() calls ip_connect() to connect a socket, but
2556 if the "connect()" function timed out, ip_connect() used to close the
2557 socket. However, verify_get_ident() also closes the socket later, and in
2558 between Exim writes to the log, which may get opened at this point. When
2559 the socket was closed in ip_connect(), the log could get the same file
2560 descriptor number as the socket. This naturally causes chaos. The fix is
2561 not to close the socket in ip_connect(); the socket should be closed by
2562 the function that creates it. There was only one place in the code where
2563 this was missing, in the iplookup router, which I don't think anybody now
2564 uses, but I've fixed it anyway.

2591 (3) Reset the variables that are obtained from the first argument of
2592 ${prvscheck and used in the second argument before leaving the code,
2593 because their memory is reclaimed, so using them afterwards may do
2594 silly things.

2621 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2622 not being looked up in the rDNS to get a host name, Exim was showing the
2623 IP address twice in Received: lines, even though the IP addresses were
2624 identical. For example:
2625
2626 Received: from [1.2.3.4] (helo=[1.2.3.4])
2627
2628 However, if the real host name was known, it was omitting the HELO data

2722 addresses acquired from the DNS when checking that the found name did
2723 have the original IP as one of its addresses. Since any found IPv6
2724 addresses are likely to be in abbreviated form, the comparison could
2725 fail. Luckily, there already exists a function for doing the comparison
2726 by converting both addresses to binary, so now that is used instead of

TK
2764Exim version 4.53
2765-----------------

2767TK/01 Added the "success_on_redirect" address verification option. See
2768 NewStuff for rationale and an example.

PH
2772PH/02 Patch to exigrep to allow it to work on syslog lines.
2773
5b68f6e4
PH
2774PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
2775 fread() to skip over the body file's header line, because in Cygwin the
2776 header line is locked and is inaccessible.
2777
1ab52c69
PH
2778PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
2779 co-exist for some time) to make it clear that it is the Exim ID that is
2780 referenced, not the Message-ID: header line.
2781
b07e6aa3
PH
2782PH/05 Replaced all Tom's calls to snprintf() with calls to the internal
2783 string_format() function, because snprintf() does not exist on all
2784 operating systems.
2785
254e032f
PH
2786PH/06 The use of forbid_filter_existstest now also locks out the use of the
2787 ${stat: expansion item.
2788
3af76a81
PH
2789PH/07 Changed "SMTP protocol violation: synchronization error" into "SMTP
2790 protocol synchronization error", to keep the pedants happy.
2791
2548ba04
PH
2792PH/08 Arrange for USE_INET_NTOA_FIX to be set in config.h for AIX systems as
2793 well as for IRIX systems, when gcc is being used. See the host.c source
2794 file for comments.

2799 setting.

2801PH/11 Added support for the IGNOREQUOTA extension to LMTP, both to the lmtp
2802 transport and to the smtp transport in LMTP mode.

PH
2804TK/02 Remove one case of BASE64 error detection FTTB (undocumented anyway).
2805
af46795e
PH
2806PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
2807 run a filter in a subprocess. This could lead to confusion in subsequent
2808 lookups in the parent process. There should also be a search_tidyup() at
2809 the end of the subprocess.
2810
d7b47fd0
PH
2811PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
2812 only if the host matched helo_try_verify_hosts, which caused the
2813 verification to occur when the EHLO/HELO command was issued. The ACL just
2814 tested the remembered result. Now, if a previous verification attempt has
2815 not happened, "verify = helo" does it there and then.

2821PH/14 A reference to $reply_address when Reply-to: was empty and From: did not

PH
2834PH/20 If a delivery was routed to a non-standard port by means of an SRV
2835 record, the port was not correctly logged when the outgoing_port log
2836 selector was set (it logged the transort's default port).

7cd1141b
PH
2838PH/21 Added support for host-specific ports to manualroute, queryprogram,
2839 fallback_hosts, and "hosts" in the smtp transport.

2841PH/22 If the log selector "outgoing_port" is set, the port is now also given on
2842 host errors such as "Connection refused".
2843
750af86e
PH
2844PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
2845 authentication with radiusclient 0.4.9:
2846
2847 - Error returned from rc_read_config was caught wrongly
2848 - Username/password not passed on to radius server due to wrong length.
2849
2850 The presumption is that some radiusclient API changes for 4.51/PH/17
2851 were not taken care of correctly. The code is still untested by me (my
2852 Linux distribution still has 0.3.2 of radiusclient), but it was
2853 contributed by a Radius user.

2855PH/24 When doing a callout, the value of $domain wasn't set correctly when
2856 expanding the "port" option of the smtp transport.

5dd9625b
PH
2868PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
2869 commands, but it was not correctly comparing the address with the actual
2870 client host address. Thus, it would show the EHLO address in Received:
2871 header lines when this was not necessary.

PH
2873PH/27 Added the % operator to ${eval:}.

ba18e66a
PH
2875PH/28 Exim tries to create and chdir to its spool directory when it starts;
2876 it should be ignoring failures (because with -C, for example, it has lost
2877 privilege). It wasn't ignoring creation failures other than "already
2878 exists".

2884 because an input line was too long, either on its own, or by virtue of

PH
2885 too many continuations, the temporary file was not being removed, and the

2895
2896PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
2897 Local/Makefile (with some defaults set). These are used in built scripts
2898 such as exicyclog, but they have never been used in the exim_install
2899 script (though there are many overriding facilities there). I have
2900 arranged that the exim_install script now takes note of these two
2901 settings.

2fe1a124
PH
2905PH/36 When a locally submitted message by a trusted user did not contain a
2906 From: header, and the sender address was obtained from -f or from an SMTP
2907 MAIL command, and the trusted user did not use -F to supply a sender
2908 name, $originator_name was incorrectly used when constructing a From:
2909 header. Furthermore, $originator_name was used for submission mode
2910 messages from external hosts without From: headers in a similar way,
2911 which is clearly wrong.
2912
8800895a
PH
2913PH/37 Added control=suppress_local_fixups.
2914
ccfdb010
PH
2915PH/38 When log_selector = +received_sender was set, and the addition of the
2916 sender made the log line's construction buffer exactly full, or one byte
2917 less than full, an overflow happened when the terminating "\n" was
2918 subsequently added.
2919
1130bfb0
PH
2920PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry
2921 when the result of a list match is failure because a DNS lookup failed.

2926 the "build-* directories that it finds.

95d1f782
PH
2928PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP
2929 address in a domain literal was a prefix of an interface address.
2930
fd6de02e
PH
2931PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains
2932 when verifying a sender address, unless rewrite_headers is false.

bef5a11f
PH
2944PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
2945 avoiding the need to install special zones in a real server. This is
2946 backwards compatible; if it can't find the fake resolver, it drops back.
2947 Thus, both old and new test suites can be run.

0154e85a
TF
2977TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
2978 if the DNS of the sending site is misconfigured. This is quite a

PH
2991PH/01 When a transport filter timed out in a pipe delivery, and the pipe

PH
3001PH/03 The warning log line about a condition test deferring for a "warn" verb
3002 was being output only once per connection, rather than after each
3003 occurrence (because it was using the same function as for successful
3004 "warn" verbs). This seems wrong, so I have changed it.

87ba3f5f
PH
3006TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3007 it should not have, which might have caused a crash in the right
3008 circumstances, but probably never did.
3009
3010PH/04 Installed a modified version of Tony Finch's patch to make submission
3011 mode fix the return path as well as the Sender: header line, and to
3012 add a /name= option so that you can make the user's friendly name appear
3013 in the header line.

415c8f3b
PH
3024PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3025 with the definition in sysexits.h (which is #included earlier).
3026 Fortunately, Exim does not actually use EX_OK. The code used to try to
3027 preserve the sysexits.h value, by assumimg that macro definitions were
3028 scanned for macro replacements. I have been disabused of this notion,
3029 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 3030
958541e9
PH
3031PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3032 in the smtp transport. When a block could not be written in a single
3033 write() function, the timeout was being re-applied to each part-write.
3034 This seems wrong - if the receiver was accepting one byte at a time it
3035 would take for ever. The timeout is now adjusted when this happens. It
3036 doesn't have to be particularly precise.

3065TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.

3070PH/08 The ${def test on a variable was returning false if the variable's

3073
3074PH/09 The syntax error of a character other than { following "${if
3075 def:variable_name" (after optional whitespace) was not being diagnosed.
3076 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an

PH
3102PH/15 The code I had for printing potentially long long variables in PH/11

c6c2dc1d
PH
3105 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T

PH
3109PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3110 the configuration file to be ":syslog", then the script "guesses" where
3111 the logs files are, rather than using the compiled in default. In our
3112 case the guess is not the same as the compiled default, so the script
3113 suddenly stopped working when I started to use syslog. The patch checks
3114 to see if log_file_path is "". If so, it attempts to read it from exim
3115 with no configuration file to get the compiled in version, before it
3116 falls back to the previous guessing code."

3125PH/18 If the "use_postmaster" option was set for a recipient callout together

3131 patch removes a few documentation additions to RFC 3028, because the

3165 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3166 picked up on a user's system that detects such things. There doesn't seem
3167 to be a gcc warning option for this - only an attribute that has to be
3168 put on the function's prototype. It seems that in Fedora Core 4 they have
3169 set this on a number of new functions. No doubt there will be more in due
3170 course.

3172PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3173 specify a transport. However, if an address that was verified by such a
3174 router was the subject of a callout, Exim crashed because it tried to
3175 read the rcpt_include_affixes from the non-existent transport. Now it
3176 just assumes that the setting of that option is false. This bug was
3177 introduced by 4.51/PH/31.

3187PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3188 aren't the modern standard, and it seems that some systems' include files
3189 don't always have them. Exim was already checking for some of the newer
3190 ones like T_AAAA, and defining it itself. I've added checks for all the
3191 record types that Exim uses.

PH
3193PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3194 not automatically generating a new one, as it is supposed to. This
3195 prevented TLS from working. If the file did exist, but contained invalid
3196 data, a new version was generated, as expected. It was only the case of a
3197 non-existent file that was broken.

3208PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3209 the use of a port name that isn't defined in /etc/services) occurred, the
3210 message was deferred as in a normal delivery, and thus remained on the
3211 spool, instead of being failed because of the mua_wrapper setting. This
3212 is now fixed, and I tidied up some of the mua_wrapper messages at the
3213 same time.

3215SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3242PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3243 to test Sieve filters that use "vacation".
3244
3245PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3246 that changes the way the GnuTLS parameters are stored in the cache file.
3247 The new format can be generated externally. For backward compatibility,
3248 if the data in the cache doesn't make sense, Exim assumes it has read an
3249 old-format file, and it generates new data and writes a new file. This
3250 means that you can't go back to an older release without removing the
3251 file.
3252
3253PH/03 A redirect router that has both "unseen" and "one_time" set does not
3254 work if there are any delivery delays because "one_time" forces the
3255 parent to be marked "delivered", so its unseen clone is never tried
3256 again. For this reason, Exim now forbids the simultaneous setting of
3257 these two options.
3258
3259PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3260 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3261 entry if you want to know the details. The fix, however, neglected to
3262 consider the case when local delivery batching is involved. The test for
3263 "previously delivered" was not happening when checking to see if an
3264 address could be batched with a previous (undelivered) one; under
3265 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3266 address.
1a46a8c5
PH
3267
3268PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3269 in its include files, and this causes problems building Exim.
3270
3271PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3272 header_syntax) but Exim was just ignoring anything given after a slash.
3273 In particular, this caused confusion with an attempt to use "verify =
3274 reverse_host_lookup/defer_ok". An error is now given when options are
3275 supplied for verify items that do not have them. (Maybe reverse_host_
3276 lookup should have a defer_ok option, but that's a different point.)
3277
3278PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3279 defined by RFC 821) to 2048, because there were problems with some AUTH
3280 commands, and RFC 1869 says the size should be increased for extended
3281 SMTP commands that take arguments.
3282
3283PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3284 Finch).

3314 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3315 negation of where the condition IS allowed.

PH
3328PH/19 When an Exim process that is running as root has to create an Exim log
3329 file, it does so in a subprocess that runs as exim:exim so as to get the
3330 ownership right at creation (otherwise, other Exim processes might see
3331 the file with the wrong ownership). There was no test for failure of this
3332 fork() call, which would lead to the process getting stuck as it waited
3333 for a non-existent subprocess. Forks do occasionally fail when resources
3334 run out. I reviewed all the other calls to fork(); they all seem to check
3335 for failure.

PH
3337PH/20 When checking for unexpected SMTP input at connect time (before writing
3338 the banner), Exim was not dealing correctly with a non-positive return
3339 from the read() function. If the client had disconnected by this time,
3340 the result was a log entry for a synchronization error with an empty
3341 string after "input=" when read() returned zero. If read() returned -1
3342 (an event I could not check), uninitialized data bytes were printed.
3343 There were reports of junk text (parts of files, etc) appearing after
3344 "input=".
