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

18 function when detected.

36Exim version 4.83
37-----------------
38
39TF/01 Correctly close the server side of TLS when forking for delivery.
40
41 When a message was received over SMTP with TLS, Exim failed to clear up
42 the incoming connection properly after forking off the child process to
43 deliver the message. In some situations the subsequent outgoing
44 delivery connection happened to have the same fd number as the incoming
45 connection previously had. Exim would try to use TLS and fail, logging
46 a "Bad file descriptor" error.

292TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
293
294 When a queue runner is handling a message, Exim first routes the
295 recipient addresses, during which it prunes them based on the retry
296 hints database. After that it attempts to deliver the message to
297 any remaining recipients. It then updates the hints database using
298 the retry rules.
299
300 So if a recipient address works intermittently, it can get repeatedly
301 deferred at routing time. The retry hints record remains fresh so the
302 address never reaches the final cutoff time.
303
304 This is a fairly common occurrence when a user is bumping up against
305 their storage quota. Exim had some logic in its local delivery code
306 to deal with this. However it did not apply to per-recipient defers
307 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
308
1ddeb334
TF
309 This change adds a proper retry rule check during routing so that the
310 final cutoff time is checked against the message's age. We only do
311 this check if there is an address retry record and there is not a
312 domain retry record; this implies that previous attempts to handle
313 the address had the retry_use_local_parts option turned on. We use
314 this as an approximation for the destination being like a local
315 delivery, as in LMTP.
67bd1ab3
TF
316
317 I suspect this new check makes the old local delivery cutoff check
318 redundant, but I have not verified this so I left the code in place.

324 Resent-From: f
325
326 When I ran the test suite under the user fanf2, Exim expanded
327 the header to contain my full name, whereas it should have added
328 a Resent-Sender: header. It erroneously treats any prefix of the
329 username as equal to the username.

331 This change corrects that bug.

352JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
353 Server implementation by Todd Lyons, client by JH.
354 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
355 config variable "prdr_enable" controls whether the server
356 advertises the facility. If the client requests PRDR a new
357 acl_data_smtp_prdr ACL is called once for each recipient, after
358 the body content is received and before the acl_smtp_data ACL.
359 The client is controlled by bolth of: a hosts_try_prdr option
360 on the smtp transport, and the server advertisement.
361 Default client logging of deliveries and rejections involving
362 PRDR are flagged with the string "PRDR".

640TF/03 Make the exiwhat support code safe for signals. Previously Exim might
641 lock up or crash if it happened to be inside a call to libc when it
642 got a SIGUSR1 from exiwhat.
643
644 The SIGUSR1 handler appends the current process status to the process
645 log which is later printed by exiwhat. It used to use the general
646 purpose logging code to do this, but several functions it calls are
647 not safe for signals.
648
649 The new output code in the SIGUSR1 handler is specific to the process
650 log, and simple enough that it's easy to inspect for signal safety.
651 Removing some special cases also simplifies the general logging code.
652 Removing the spurious timestamps from the process log simplifies
653 exiwhat.
654
c99ce5c9
TF
655TF/04 Improved ratelimit ACL condition.
656
657 The /noupdate option has been deprecated in favour of /readonly which
658 has clearer semantics. The /leaky, /strict, and /readonly update modes
659 are mutually exclusive. The update mode is no longer included in the
660 database key; it just determines when the database is updated. (This
661 means that when you upgrde Exim will forget old rate measurements.)
662
663 Exim now checks that the per_* options are used with an update mode that
664 makes sense for the current ACL. For example, when Exim is processing a
665 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
666 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
667 must specify per_mail/readonly. If you omit the update mode it defaults to
668 /leaky where that makes sense (as before) or /readonly where required.
669
670 The /noupdate option is now undocumented but still supported for
671 backwards compatibility. It is equivalent to /readonly except that in
672 ACLs where /readonly is required you may specify /leaky/noupdate or
673 /strict/noupdate which are treated the same as /readonly.
674
675 A useful new feature is the /count= option. This is a generalization
676 of the per_byte option, so that you can measure the throughput of other
677 aggregate values. For example, the per_byte option is now equivalent
678 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
679
680 The per_rcpt option has been generalized using the /count= mechanism
681 (though it's more complicated than the per_byte equivalence). When it is
682 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
683 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
684 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
685 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
686 Note that using per_rcpt with a non-readonly update mode in more than
687 one ACL will cause the recipients to be double-counted. (The per_mail
688 and per_byte options don't have this problem.)
689
690 The handling of very low rates has changed slightly. If the computed rate
691 is less than the event's count (usually one) then this event is the first
692 after a long gap. In this case the rate is set to the same as this event's
693 count, so that the first message of a spam run is counted properly.
694
695 The major new feature is a mechanism for counting the rate of unique
696 events. The new per_addr option counts the number of different
697 recipients that someone has sent messages to in the last time period. It
698 behaves like per_rcpt if all the recipient addresses are different, but
699 duplicate recipient addresses do not increase the measured rate. Like
700 the /count= option this is a general mechanism, so the per_addr option
701 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
702 example, measure the rate that a client uses different sender addresses
703 with the options per_mail/unique=$sender_address. There are further
704 details in the main documentation.

1255 were called 'true' and it seems that C99 defines that as a reserved

1276PH/01 Another patch from the Sieve maintainer.
1277
6a3bceb1
PH
1278PH/02 When an IPv6 address is converted to a string for single-key lookup
1279 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1280 dots are used instead of colons so that keys in lsearch files need not
1281 contain colons. This was done some time before quoting was made available
1282 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1283 (notated using the quote facility) so as to distinguish them from IPv4
1284 keys. This meant that lookups for IP addresses in host lists did not work
1285 for iplsearch lookups.
1286
1287 This has been fixed by arranging for IPv6 addresses to be expressed with
1288 colons if the lookup type is iplsearch. This is not incompatible, because
1289 previously such lookups could never work.
1290
1291 The situation is now rather anomolous, since one *can* have colons in
1292 ordinary lsearch keys. However, making the change in all cases is
1293 incompatible and would probably break a number of configurations.

MH
1298MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1299 conversion specification without a maximum field width, thereby enabling
1300 a rogue spamd server to cause a buffer overflow. While nobody in their
1301 right mind would setup Exim to query an untrusted spamd server, an
1302 attacker that gains access to a server running spamd could potentially
1303 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1308MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1309 a directory entry by the name of the lookup key. Previously, if a
1310 symlink pointed to a non-existing file or a file in a directory that
1311 Exim lacked permissions to read, a lookup for a key matching that
1312 symlink would fail. Now it is enough that a matching directory entry
1313 exists, symlink or not. (Bugzilla 503.)

1390 if a client was not listed at all, or was listed with a value other than
1391 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

PH
1496PH/29 SMTP synchronization checks are implemented when a command is read -
1497 there is a check that no more input is waiting when there shouldn't be
1498 any. However, for some commands, a delay in an ACL can mean that it is
1499 some time before the response is written. In this time, more input might
1500 arrive, invalidly. So now there are extra checks after an ACL has run for
1501 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1502 pipelining has not been advertised.

PH
1514PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1516 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1517 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1518 was a macro that became an assignment, so it seemed to work. This has
1519 changed to a proper function call with a void return, hence the compile
1520 error. Exim's code has been fixed.

1551 started the daemon, but after a SIGHUP it used the Exim user (because it

1558 with PIPELINING or a stupid MUA), the error message that was given to the

58eb016e 1575PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1576 the response to the final '.' that terminates a message, but only in the
1577 case where the client has not sent further data following the '.'
1578 (unfortunately, this is allowed). However, in many cases there won't be
1579 any further data because there won't be any more messages to send. A call
1580 to select() can be used: if it shows that the input is "ready", there is
1581 either input waiting, or the socket has been closed. An attempt to read
1582 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1583 would have sent an OK response which the client would never have see.

1591Exim version 4.66
1592-----------------
1593
1594PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1595 fixed by 4.65/MH/01 (is this a record?) are fixed:
1596
1597 (i) An empty string was always treated as zero by the numeric comparison
1598 operators. This behaviour has been restored.
1599
1600 (ii) It is documented that the numeric comparison operators always treat
1601 their arguments as decimal numbers. This was broken in that numbers
1602 starting with 0 were being interpreted as octal.
1603
1604 While fixing these problems I realized that there was another issue that
1605 hadn't been noticed. Values of message_size_limit (both the global option
1606 and the transport option) were treated as octal if they started with 0.
1607 The documentation was vague. These values are now always treated as
1608 decimal, and I will make that clear in the documentation.

PH
1622PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1623 child addresses, Exim now panics and dies. Previously, because the count
1624 is held in a short int, deliveries were likely to be lost. As such a
1625 large number of recipients for a single message is ridiculous
1626 (performance will be very, very poor), I have chosen to impose a limit
1627 rather than extend the field.

1633TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1634 leftover -K file (the existence of which was triggered by #402).
1635 While we were at it, introduced process PID as part of the -K
1636 filename. This should rule out race conditions when creating
1637 these files.

1639TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1640 processing considerably. Previous code took too long for large mails,
1641 triggering a timeout which in turn triggers #401.
1642
1643TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1644 in the DK code in transports.c. sendfile() is not really portable,
1645 hence the _LINUX specificness.

1647TF/01 In the add_headers option to the mail command in an Exim filter,

1649 header after the first one which had an odd number of characters
1650 in the field name.

2b1c6e3a
PH
1652PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1653 callout verification, Exim cached a "reject" for the entire domain. This
1654 is correct for most verifications, but it is not correct for a recipient
1655 verification with use_sender or use_postmaster set, because in that case
1656 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1657 case of MAIL FROM:<> rejection from other early rejections (e.g.
1658 rejection of HELO). When verifying a recipient using a non-null MAIL
1659 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1660 Whatever the result of the callout, the value of the domain cache is
1661 left unchanged (for any other kind of callout, getting as far as trying
1662 RCPT means that the domain itself is ok).

1696PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1697 hostname. This is wrong, because it relates to the incoming message (and
1698 probably the interface on which it is arriving) and not to the outgoing
1699 callout (which could be using a different interface). This has been
1700 changed to use the value of the helo_data option from the smtp transport
1701 instead - this is what is used when a message is actually being sent. If
1702 there is no remote transport (possible with a router that sets up host
1703 addresses), $smtp_active_hostname is used.

14aa5a05 1705PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1706 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1707 (a) The code assumed that strncpy() returns a negative number on buffer
1708 overflow, which isn't the case. Replaced with Exim's string_format()
1709 function.
1710 (b) There were several signed/unsigned issues. I just did the minimum
1711 hacking in of casts. There is scope for a larger refactoring.
1712 (c) The code used strcasecmp() which is not a standard C function.
1713 Replaced with Exim's strcmpic() function.
1714 (d) The code set only $1; it now sets $auth1 as well.
1715 (e) A simple test gave the error "authentication client didn't specify
1716 service in request". It would seem that Dovecot has changed its
1717 interface. Fortunately there's a specification; I followed it and
1718 changed what the client sends and it appears to be working now.

1723PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1724 address A is aliased to B and C, where B exists and C does not. Without
1725 -v the output is "A verified" because verification stops after a
1726 successful redirection if more than one address is generated. However,
1727 with -v the child addresses are also verified. Exim was outputting "A
1728 failed to verify" and then showing the successful verification for C,
1729 with its parentage. It now outputs "B failed to verify", showing B's
1730 parentage before showing the successful verification of C.

1733 look up a TXT record in a specific list after matching in a combined
1734 list.
1735
322050c2
PH
1736PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1737 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1738 they consult the DNS. I had assumed they would set it the way they
1739 wanted; and indeed my experiments on Linux seem to show that in some
1740 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1741 To be on the safe side, however, I have now made the interface to
1742 host_find_byname() similar to host_find_bydns(), with an argument
1743 containing the DNS resolver options. The host_find_byname() function now
1744 sets these options at its start, just as host_find_bydns() does. The smtp
1745 transport options dns_qualify_single and dns_search_parents are passed to
1746 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1747 of host_find_byname() use the default settings of RES_DEFNAMES
1748 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1750PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1751 spool_read_header() do less string testing, by means of a preliminary
1752 switch on the second character of optional "-foo" lines. (This is
1753 overdue, caused by the large number of possibilities that now exist.
1754 Originally there were few.) While I was there, I also converted the
1755 str(n)cmp tests so they don't re-test the leading "-" and the first
1756 character, in the hope this might squeeze out yet more improvement.
1757

PH
1758PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1759 flag allowing group syntax was set by the header_syntax check but not
1760 turned off, possible causing trouble later; (2) The flag was not being
1761 set at all for the header_verify test, causing "group"-style headers to
1762 be rejected. I have now set it in this case, and also caused header_
1763 verify to ignore an empty address taken from a group. While doing this, I
1764 came across some other cases where the code for allowing group syntax
1765 while scanning a header line wasn't quite right (mostly, not resetting
1766 the flag correctly in the right place). These bugs could have caused
1767 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1769PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1770 with the "reply" argument non-NULL. The code, however (which originally
1771 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1772 but it didn't always do it. This confused somebody who was copying the
1773 code for some other use. I have removed all the tests.

411ef850
PH
1775PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1776 feature that was used to support insecure browsers during the U.S. crypto
1777 embargo. It requires special client support, and Exim is probably the
1778 only MTA that supported it -- and would never use it because real RSA is
1779 always available. This code has been removed, because it had the bad
1780 effect of slowing Exim down by computing (never used) parameters for the
1781 RSA_EXPORT functionality.
1782
7befa435
PH
1783PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1784 authenticator to fail if there's a tab character in the incoming data
1785 (there should never be unless someone is messing about, as it's supposed
1786 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1787 if the connection is using TLS or if the remote IP is the same as the
1788 local IP, and the "valid-client-cert option" if a client certificate has
1789 been verified.

1820
1821PH/30 Exim was sometimes attempting to deliver messages that had suffered
1822 address errors (4xx response to RCPT) over the same connection as other
1823 messages routed to the same hosts. Such deliveries are always "forced",
1824 so retry times are not inspected. This resulted in far too many retries
1825 for the affected addresses. The effect occurred only when there were more
1826 hosts than the hosts_max_try setting in the smtp transport when it had
1827 the 4xx errors. Those hosts that it had tried were not added to the list
1828 of hosts for which the message was waiting, so if all were tried, there
1829 was no problem. Two fixes have been applied:
1830
1831 (i) If there are any address or message errors in an SMTP delivery, none
1832 of the hosts (tried or untried) are now added to the list of hosts
1833 for which the message is waiting, so the message should not be a
1834 candidate for sending over the same connection that was used for a
1835 successful delivery of some other message. This seems entirely
1836 reasonable: after all the message is NOT "waiting for some host".
1837 This is so "obvious" that I'm not sure why it wasn't done
1838 previously. Hope I haven't missed anything, but it can't do any
1839 harm, as the worst effect is to miss an optimization.
1840
1841 (ii) If, despite (i), such a delivery is accidentally attempted, the
1842 routing retry time is respected, so at least it doesn't keep
1843 hammering the server.

PH
1858PH/35 The error "getsockname() failed: connection reset by peer" was being
1859 written to the panic log as well as the main log, but it isn't really
1860 panic-worthy as it just means the connection died rather early on. I have
1861 removed the panic log writing for the ECONNRESET error when getsockname()
1862 fails.
1863
48c7f9e2
PH
1864PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1865 runs only) independently of the message's sender address. This meant
1866 that, if the 4xx error was in fact related to the sender, a different
1867 message to the same recipient with a different sender could confuse
1868 things. In particualar, this can happen when sending to a greylisting
1869 server, but other circumstances could also provoke similar problems.
1870 I have changed the default so that the retry time for these errors is now
1871 based a combination of the sender and recipient addresses. This change
1872 can be overridden by setting address_retry_include_sender=false in the
1873 smtp transport.

2141PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2143 Unfortunately, if there is a major crisis, such as a disk failure,
2144 tcp-wrappers gives "deny", whereas what one would like would be some
2145 kind of temporary error. A kludge has been added to help with this.
2146 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2147 554 error is used if errno is still zero or contains ENOENT (which occurs
2148 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2149 451 error is used.

2188 code found IPv4 interfaces correctly, but gave incorrect values for the
2189 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2190 that it would not match correctly against @[] and not recognize the IPv6
2191 addresses as local.

2234 autoreply, Exim could try to deliver to a non-existent relative file

2259 suitable debugging ouput when -d is set.

2269 additional section of a DNS packet that returns MX or SRV records.
2270 Instead, it always explicitly searches for A/AAAA records. This avoids
2271 major problems that occur when a DNS server includes only records of one
2272 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2273 fixed another bug: if SRV records were looked up and the corresponding
2274 address records were *not* found in the additional section, the port
2275 values from the SRV records were lost.

2277PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
2285PH/19 When calculating a retry time, Exim used to measure the "time since
2286 failure" by looking at the "first failed" field in the retry record. Now
2287 it does not use this if it is later than than the arrival time of the
2288 message. Instead it uses the arrival time. This makes for better
2289 behaviour in cases where some deliveries succeed, thus re-setting the
2290 "first failed" field. An example is a quota failure for a huge message
2291 when small messages continue to be delivered. Without this change, the
2292 "time since failure" will always be short, possible causing more frequent
2293 delivery attempts for the huge message than are intended.

PH
2390PH/42 The content-scanning code uses fopen() to create files in which to put
2391 message data. Previously it was not paying any attention to the mode of
2392 the files. Exim runs with umask(0) because the rest of the code creates
2393 files with open(), and sets the required mode explicitly. Thus, these
2394 files were ending up world-writeable. This was not a big issue, because,
2395 being within the spool directory, they were not world-accessible. I have
2396 created a function called modefopen, which takes an additional mode
2397 argument. It sets umask(777), creates the file, chmods it to the required
2398 mode, then resets the umask. All the relevant calls to fopen() in the
2399 content scanning code have been changed to use this function.

2411 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2434PH/52 Two bugs concerned with error handling when the smtp transport is
2435 used in LMTP mode:
2436
2437 (i) Exim was not creating retry information for temporary errors given
2438 for individual recipients after the DATA command when the smtp transport
2439 was used in LMTP mode. This meant that they could be retried too
2440 frequently, and not timed out correctly.
2441
2442 (ii) Exim was setting the flag that allows error details to be returned
2443 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2444 recipients that were returned after the DATA command.
2445
2446PH/53 This is related to PH/52, but is more general: for any failing address,
2447 when detailed error information was permitted to be returned to the
2448 sender, but the error was temporary, then after the final timeout, only
2449 "retry timeout exceeded" was returned. Now it returns the full error as
2450 well as "retry timeout exceeded".

2520PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2521 function verify_get_ident() calls ip_connect() to connect a socket, but
2522 if the "connect()" function timed out, ip_connect() used to close the
2523 socket. However, verify_get_ident() also closes the socket later, and in
2524 between Exim writes to the log, which may get opened at this point. When
2525 the socket was closed in ip_connect(), the log could get the same file
2526 descriptor number as the socket. This naturally causes chaos. The fix is
2527 not to close the socket in ip_connect(); the socket should be closed by
2528 the function that creates it. There was only one place in the code where
2529 this was missing, in the iplookup router, which I don't think anybody now
2530 uses, but I've fixed it anyway.

2554 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2556
2557 (3) Reset the variables that are obtained from the first argument of
2558 ${prvscheck and used in the second argument before leaving the code,
2559 because their memory is reclaimed, so using them afterwards may do
2560 silly things.
2561
2562 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2563 one (it's much easier than Tom thought :-).

2587 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2588 not being looked up in the rDNS to get a host name, Exim was showing the
2589 IP address twice in Received: lines, even though the IP addresses were
2590 identical. For example:
2591
2592 Received: from [1.2.3.4] (helo=[1.2.3.4])
2593
2594 However, if the real host name was known, it was omitting the HELO data
2595 if it matched the actual IP address. This has been tidied up so that it
2596 doesn't show the same IP address twice.

2627 in the messages that it generates (bounce messages and others, such as
2628 warnings). In the case of bounce messages for non-SMTP mesages, there was
2629 also a typo: it was using "Auto_submitted" (underscore instead of
2630 hyphen). Since every message generated by Exim is necessarily in response
2631 to another message, thes have all been changed to:

2688 addresses acquired from the DNS when checking that the found name did
2689 have the original IP as one of its addresses. Since any found IPv6
2690 addresses are likely to be in abbreviated form, the comparison could
2691 fail. Luckily, there already exists a function for doing the comparison
2692 by converting both addresses to binary, so now that is used instead of
2693 the text comparison.

2991 with the definition in sysexits.h (which is #included earlier).
2992 Fortunately, Exim does not actually use EX_OK. The code used to try to
2993 preserve the sysexits.h value, by assumimg that macro definitions were
2994 scanned for macro replacements. I have been disabused of this notion,
2995 so now the code just undefines EX_OK before #including unistd.h.

3000 This seems wrong - if the receiver was accepting one byte at a time it
3001 would take for ever. The timeout is now adjusted when this happens. It
3002 doesn't have to be particularly precise.

3153PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3154 aren't the modern standard, and it seems that some systems' include files
3155 don't always have them. Exim was already checking for some of the newer
3156 ones like T_AAAA, and defining it itself. I've added checks for all the
3157 record types that Exim uses.

3159PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3160 not automatically generating a new one, as it is supposed to. This
3161 prevented TLS from working. If the file did exist, but contained invalid
3162 data, a new version was generated, as expected. It was only the case of a
3163 non-existent file that was broken.

3176 message was deferred as in a normal delivery, and thus remained on the
3177 spool, instead of being failed because of the mua_wrapper setting. This
3178 is now fixed, and I tidied up some of the mua_wrapper messages at the
3179 same time.

3210
3211PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3212 that changes the way the GnuTLS parameters are stored in the cache file.
3213 The new format can be generated externally. For backward compatibility,
3214 if the data in the cache doesn't make sense, Exim assumes it has read an
3215 old-format file, and it generates new data and writes a new file. This
3216 means that you can't go back to an older release without removing the
3217 file.
3218
3219PH/03 A redirect router that has both "unseen" and "one_time" set does not
3220 work if there are any delivery delays because "one_time" forces the
3221 parent to be marked "delivered", so its unseen clone is never tried
3222 again. For this reason, Exim now forbids the simultaneous setting of
3223 these two options.
3224
3225PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3226 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3227 entry if you want to know the details. The fix, however, neglected to
3228 consider the case when local delivery batching is involved. The test for
3229 "previously delivered" was not happening when checking to see if an
3230 address could be batched with a previous (undelivered) one; under
3231 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3232 address.

3233
3234PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3235 in its include files, and this causes problems building Exim.
3236
3237PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3238 header_syntax) but Exim was just ignoring anything given after a slash.
3239 In particular, this caused confusion with an attempt to use "verify =
3240 reverse_host_lookup/defer_ok". An error is now given when options are
3241 supplied for verify items that do not have them. (Maybe reverse_host_
3242 lookup should have a defer_ok option, but that's a different point.)
3243
3244PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3245 defined by RFC 821) to 2048, because there were problems with some AUTH

3247 SMTP commands that take arguments.

3294PH/19 When an Exim process that is running as root has to create an Exim log
3295 file, it does so in a subprocess that runs as exim:exim so as to get the
3296 ownership right at creation (otherwise, other Exim processes might see
3297 the file with the wrong ownership). There was no test for failure of this
3298 fork() call, which would lead to the process getting stuck as it waited
3299 for a non-existent subprocess. Forks do occasionally fail when resources
3300 run out. I reviewed all the other calls to fork(); they all seem to check
3301 for failure.

3303PH/20 When checking for unexpected SMTP input at connect time (before writing

3305 from the read() function. If the client had disconnected by this time,
3306 the result was a log entry for a synchronization error with an empty
3307 string after "input=" when read() returned zero. If read() returned -1
3308 (an event I could not check), uninitialized data bytes were printed.

3319
c5ddb310
PH
3320PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3321 hadn't been configured. The fix is from Juergen Kreileder, who
3322 understands it better than I do:
3323
3324 "Here's what I see happening with three configured cyrus_sasl
3325 authenticators configured (plain, login, cram-md5):
3326
3327 On startup auth_cyrus_sasl_init() gets called for each of these.
3328 This means three calls to sasl_listmech() without a specified mech_list.
3329 => SASL tests which mechs of all available mechs actually work
3330 => three warnings about OTP not working
3331 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3332
3333 With the patch, sasl_listmech() also gets called three times. But now
3334 SASL's mech_list option is set to the server_mech specified in the the
3335 authenticator. Or in other words, the answer from sasl_listmech()
3336 gets limited to just the mech you're testing for (which is different
3337 for each call.)
3338 => the return list contains just 'plain' or 'login', 'cram-md5' or
3339 nothing depending on the value of ob->server_mech.
3340
3341 I've just tested the patch: Authentication still works fine,
3342 unavailable mechs specified in the exim configuration are still
3343 caught, and the auth.log warnings about OTP are gone."
