TL
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.

31Exim version 4.83
32-----------------
33
34TF/01 Correctly close the server side of TLS when forking for delivery.
35
36 When a message was received over SMTP with TLS, Exim failed to clear up
37 the incoming connection properly after forking off the child process to
38 deliver the message. In some situations the subsequent outgoing
39 delivery connection happened to have the same fd number as the incoming
40 connection previously had. Exim would try to use TLS and fail, logging
41 a "Bad file descriptor" error.

TF
287TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
288
289 When a queue runner is handling a message, Exim first routes the
290 recipient addresses, during which it prunes them based on the retry
291 hints database. After that it attempts to deliver the message to
292 any remaining recipients. It then updates the hints database using
293 the retry rules.
294
295 So if a recipient address works intermittently, it can get repeatedly
296 deferred at routing time. The retry hints record remains fresh so the
297 address never reaches the final cutoff time.
298
299 This is a fairly common occurrence when a user is bumping up against
300 their storage quota. Exim had some logic in its local delivery code
301 to deal with this. However it did not apply to per-recipient defers
302 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
303
1ddeb334
TF
304 This change adds a proper retry rule check during routing so that the
305 final cutoff time is checked against the message's age. We only do
306 this check if there is an address retry record and there is not a
307 domain retry record; this implies that previous attempts to handle
308 the address had the retry_use_local_parts option turned on. We use
309 this as an approximation for the destination being like a local
310 delivery, as in LMTP.
67bd1ab3
TF
311
312 I suspect this new check makes the old local delivery cutoff check
313 redundant, but I have not verified this so I left the code in place.

317 Test 0254 submits a message to Exim with the header

319 Resent-From: f
320
321 When I ran the test suite under the user fanf2, Exim expanded
322 the header to contain my full name, whereas it should have added
323 a Resent-Sender: header. It erroneously treats any prefix of the
324 username as equal to the username.
325
326 This change corrects that bug.

347JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
348 Server implementation by Todd Lyons, client by JH.
349 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
350 config variable "prdr_enable" controls whether the server
351 advertises the facility. If the client requests PRDR a new
352 acl_data_smtp_prdr ACL is called once for each recipient, after
353 the body content is received and before the acl_smtp_data ACL.
354 The client is controlled by bolth of: a hosts_try_prdr option
355 on the smtp transport, and the server advertisement.
356 Default client logging of deliveries and rejections involving
357 PRDR are flagged with the string "PRDR".

635TF/03 Make the exiwhat support code safe for signals. Previously Exim might
636 lock up or crash if it happened to be inside a call to libc when it
637 got a SIGUSR1 from exiwhat.
638
639 The SIGUSR1 handler appends the current process status to the process
640 log which is later printed by exiwhat. It used to use the general
641 purpose logging code to do this, but several functions it calls are
642 not safe for signals.
643
644 The new output code in the SIGUSR1 handler is specific to the process
645 log, and simple enough that it's easy to inspect for signal safety.
646 Removing some special cases also simplifies the general logging code.
647 Removing the spurious timestamps from the process log simplifies
648 exiwhat.
649

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

1250 were called 'true' and it seems that C99 defines that as a reserved

1252 not include C99-style headers which use bools without triggering

1270
1271PH/01 Another patch from the Sieve maintainer.
1272
6a3bceb1
PH
1273PH/02 When an IPv6 address is converted to a string for single-key lookup
1274 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1275 dots are used instead of colons so that keys in lsearch files need not
1276 contain colons. This was done some time before quoting was made available
1277 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1278 (notated using the quote facility) so as to distinguish them from IPv4
1279 keys. This meant that lookups for IP addresses in host lists did not work
1280 for iplsearch lookups.
1281
1282 This has been fixed by arranging for IPv6 addresses to be expressed with
1283 colons if the lookup type is iplsearch. This is not incompatible, because
1284 previously such lookups could never work.
1285
1286 The situation is now rather anomolous, since one *can* have colons in
1287 ordinary lsearch keys. However, making the change in all cases is
1288 incompatible and would probably break a number of configurations.

MH
1293MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1294 conversion specification without a maximum field width, thereby enabling
1295 a rogue spamd server to cause a buffer overflow. While nobody in their
1296 right mind would setup Exim to query an untrusted spamd server, an
1297 attacker that gains access to a server running spamd could potentially
1298 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1303MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1304 a directory entry by the name of the lookup key. Previously, if a
1305 symlink pointed to a non-existing file or a file in a directory that
1306 Exim lacked permissions to read, a lookup for a key matching that
1307 symlink would fail. Now it is enough that a matching directory entry
1308 exists, symlink or not. (Bugzilla 503.)

1385 if a client was not listed at all, or was listed with a value other than
1386 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1387 the condition was not true (as it should be), so access was not denied.

PH
1491PH/29 SMTP synchronization checks are implemented when a command is read -
1492 there is a check that no more input is waiting when there shouldn't be
1493 any. However, for some commands, a delay in an ACL can mean that it is
1494 some time before the response is written. In this time, more input might
1495 arrive, invalidly. So now there are extra checks after an ACL has run for
1496 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1497 pipelining has not been advertised.

PH
1509PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1511 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1512 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1513 was a macro that became an assignment, so it seemed to work. This has
1514 changed to a proper function call with a void return, hence the compile
1515 error. Exim's code has been fixed.

1546 started the daemon, but after a SIGHUP it used the Exim user (because it

1553 with PIPELINING or a stupid MUA), the error message that was given to the

1573 (unfortunately, this is allowed). However, in many cases there won't be
1574 any further data because there won't be any more messages to send. A call
1575 to select() can be used: if it shows that the input is "ready", there is
1576 either input waiting, or the socket has been closed. An attempt to read
1577 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1578 would have sent an OK response which the client would never have see.

1586Exim version 4.66
1587-----------------
1588
1589PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1590 fixed by 4.65/MH/01 (is this a record?) are fixed:
1591
1592 (i) An empty string was always treated as zero by the numeric comparison
1593 operators. This behaviour has been restored.
1594
1595 (ii) It is documented that the numeric comparison operators always treat
1596 their arguments as decimal numbers. This was broken in that numbers
1597 starting with 0 were being interpreted as octal.
1598
1599 While fixing these problems I realized that there was another issue that
1600 hadn't been noticed. Values of message_size_limit (both the global option
1601 and the transport option) were treated as octal if they started with 0.
1602 The documentation was vague. These values are now always treated as
1603 decimal, and I will make that clear in the documentation.

1617PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1618 child addresses, Exim now panics and dies. Previously, because the count
1619 is held in a short int, deliveries were likely to be lost. As such a
1620 large number of recipients for a single message is ridiculous
1621 (performance will be very, very poor), I have chosen to impose a limit
1622 rather than extend the field.

1628TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1629 leftover -K file (the existence of which was triggered by #402).
1630 While we were at it, introduced process PID as part of the -K
1631 filename. This should rule out race conditions when creating
1632 these files.

1634TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1635 processing considerably. Previous code took too long for large mails,
1636 triggering a timeout which in turn triggers #401.
1637
1638TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1639 in the DK code in transports.c. sendfile() is not really portable,

1642TF/01 In the add_headers option to the mail command in an Exim filter,

1645 in the field name.

2b1c6e3a
PH
1647PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1648 callout verification, Exim cached a "reject" for the entire domain. This
1649 is correct for most verifications, but it is not correct for a recipient
1650 verification with use_sender or use_postmaster set, because in that case
1651 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1652 case of MAIL FROM:<> rejection from other early rejections (e.g.
1653 rejection of HELO). When verifying a recipient using a non-null MAIL
1654 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1655 Whatever the result of the callout, the value of the domain cache is
1656 left unchanged (for any other kind of callout, getting as far as trying
1657 RCPT means that the domain itself is ok).

1691PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1692 hostname. This is wrong, because it relates to the incoming message (and
1693 probably the interface on which it is arriving) and not to the outgoing
1694 callout (which could be using a different interface). This has been
1695 changed to use the value of the helo_data option from the smtp transport
1696 instead - this is what is used when a message is actually being sent. If
1697 there is no remote transport (possible with a router that sets up host
1698 addresses), $smtp_active_hostname is used.

7befa435 1701 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1702 (a) The code assumed that strncpy() returns a negative number on buffer
1703 overflow, which isn't the case. Replaced with Exim's string_format()
1704 function.
1705 (b) There were several signed/unsigned issues. I just did the minimum
1706 hacking in of casts. There is scope for a larger refactoring.
1707 (c) The code used strcasecmp() which is not a standard C function.
1708 Replaced with Exim's strcmpic() function.
1709 (d) The code set only $1; it now sets $auth1 as well.
1710 (e) A simple test gave the error "authentication client didn't specify
1711 service in request". It would seem that Dovecot has changed its
1712 interface. Fortunately there's a specification; I followed it and
1713 changed what the client sends and it appears to be working now.

1718PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1719 address A is aliased to B and C, where B exists and C does not. Without
1720 -v the output is "A verified" because verification stops after a
1721 successful redirection if more than one address is generated. However,
1722 with -v the child addresses are also verified. Exim was outputting "A
1723 failed to verify" and then showing the successful verification for C,
1724 with its parentage. It now outputs "B failed to verify", showing B's
1725 parentage before showing the successful verification of C.

1728 look up a TXT record in a specific list after matching in a combined

1730
322050c2
PH
1731PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1732 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1733 they consult the DNS. I had assumed they would set it the way they
1734 wanted; and indeed my experiments on Linux seem to show that in some
1735 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1736 To be on the safe side, however, I have now made the interface to
1737 host_find_byname() similar to host_find_bydns(), with an argument
1738 containing the DNS resolver options. The host_find_byname() function now
1739 sets these options at its start, just as host_find_bydns() does. The smtp
1740 transport options dns_qualify_single and dns_search_parents are passed to
1741 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1742 of host_find_byname() use the default settings of RES_DEFNAMES
1743 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1745PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1746 spool_read_header() do less string testing, by means of a preliminary
1747 switch on the second character of optional "-foo" lines. (This is
1748 overdue, caused by the large number of possibilities that now exist.
1749 Originally there were few.) While I was there, I also converted the
1750 str(n)cmp tests so they don't re-test the leading "-" and the first
1751 character, in the hope this might squeeze out yet more improvement.

PH
1753PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1754 flag allowing group syntax was set by the header_syntax check but not
1755 turned off, possible causing trouble later; (2) The flag was not being
1756 set at all for the header_verify test, causing "group"-style headers to
1757 be rejected. I have now set it in this case, and also caused header_
1758 verify to ignore an empty address taken from a group. While doing this, I
1759 came across some other cases where the code for allowing group syntax
1760 while scanning a header line wasn't quite right (mostly, not resetting
1761 the flag correctly in the right place). These bugs could have caused
1762 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1764PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1765 with the "reply" argument non-NULL. The code, however (which originally
1766 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1767 but it didn't always do it. This confused somebody who was copying the
1768 code for some other use. I have removed all the tests.

411ef850
PH
1770PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1771 feature that was used to support insecure browsers during the U.S. crypto
1772 embargo. It requires special client support, and Exim is probably the
1773 only MTA that supported it -- and would never use it because real RSA is
1774 always available. This code has been removed, because it had the bad
1775 effect of slowing Exim down by computing (never used) parameters for the
1776 RSA_EXPORT functionality.

PH
1778PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1779 authenticator to fail if there's a tab character in the incoming data
1780 (there should never be unless someone is messing about, as it's supposed
1781 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1782 if the connection is using TLS or if the remote IP is the same as the
1783 local IP, and the "valid-client-cert option" if a client certificate has
1784 been verified.

1815
1816PH/30 Exim was sometimes attempting to deliver messages that had suffered
1817 address errors (4xx response to RCPT) over the same connection as other
1818 messages routed to the same hosts. Such deliveries are always "forced",
1819 so retry times are not inspected. This resulted in far too many retries
1820 for the affected addresses. The effect occurred only when there were more
1821 hosts than the hosts_max_try setting in the smtp transport when it had
1822 the 4xx errors. Those hosts that it had tried were not added to the list
1823 of hosts for which the message was waiting, so if all were tried, there
1824 was no problem. Two fixes have been applied:
1825
1826 (i) If there are any address or message errors in an SMTP delivery, none
1827 of the hosts (tried or untried) are now added to the list of hosts
1828 for which the message is waiting, so the message should not be a
1829 candidate for sending over the same connection that was used for a
1830 successful delivery of some other message. This seems entirely
1831 reasonable: after all the message is NOT "waiting for some host".
1832 This is so "obvious" that I'm not sure why it wasn't done
1833 previously. Hope I haven't missed anything, but it can't do any
1834 harm, as the worst effect is to miss an optimization.
1835
1836 (ii) If, despite (i), such a delivery is accidentally attempted, the
1837 routing retry time is respected, so at least it doesn't keep
1838 hammering the server.

PH
1853PH/35 The error "getsockname() failed: connection reset by peer" was being
1854 written to the panic log as well as the main log, but it isn't really
1855 panic-worthy as it just means the connection died rather early on. I have
1856 removed the panic log writing for the ECONNRESET error when getsockname()
1857 fails.
1858
48c7f9e2
PH
1859PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1860 runs only) independently of the message's sender address. This meant
1861 that, if the 4xx error was in fact related to the sender, a different
1862 message to the same recipient with a different sender could confuse
1863 things. In particualar, this can happen when sending to a greylisting
1864 server, but other circumstances could also provoke similar problems.
1865 I have changed the default so that the retry time for these errors is now
1866 based a combination of the sender and recipient addresses. This change
1867 can be overridden by setting address_retry_include_sender=false in the
1868 smtp transport.

2136PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2138 Unfortunately, if there is a major crisis, such as a disk failure,
2139 tcp-wrappers gives "deny", whereas what one would like would be some
2140 kind of temporary error. A kludge has been added to help with this.
2141 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2142 554 error is used if errno is still zero or contains ENOENT (which occurs
2143 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2144 451 error is used.

2180PH/01 The code for finding all the local interface addresses on a FreeBSD
2181 system running IPv6 was broken. This may well have applied to all BSD
2182 systems, as well as to others that have similar system calls. The broken
2183 code found IPv4 interfaces correctly, but gave incorrect values for the
2184 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2185 that it would not match correctly against @[] and not recognize the IPv6
2186 addresses as local.

2229 autoreply, Exim could try to deliver to a non-existent relative file
2230 name, causing unrelated and misleading errors. What now happens is that

2252 (a) Failures to set uid/gid, the current directory, or a process leader
2253 in a subprocess such as that created by queryprogram now generate
2254 suitable debugging ouput when -d is set.

2258 the subprocess without attempting to change uid/gid.

2264 additional section of a DNS packet that returns MX or SRV records.
2265 Instead, it always explicitly searches for A/AAAA records. This avoids
2266 major problems that occur when a DNS server includes only records of one
2267 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2268 fixed another bug: if SRV records were looked up and the corresponding
2269 address records were *not* found in the additional section, the port
2270 values from the SRV records were lost.

2272PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2280PH/19 When calculating a retry time, Exim used to measure the "time since
2281 failure" by looking at the "first failed" field in the retry record. Now
2282 it does not use this if it is later than than the arrival time of the
2283 message. Instead it uses the arrival time. This makes for better
2284 behaviour in cases where some deliveries succeed, thus re-setting the
2285 "first failed" field. An example is a quota failure for a huge message
2286 when small messages continue to be delivered. Without this change, the
2287 "time since failure" will always be short, possible causing more frequent
2288 delivery attempts for the huge message than are intended.

PH
2385PH/42 The content-scanning code uses fopen() to create files in which to put
2386 message data. Previously it was not paying any attention to the mode of
2387 the files. Exim runs with umask(0) because the rest of the code creates
2388 files with open(), and sets the required mode explicitly. Thus, these
2389 files were ending up world-writeable. This was not a big issue, because,
2390 being within the spool directory, they were not world-accessible. I have
2391 created a function called modefopen, which takes an additional mode
2392 argument. It sets umask(777), creates the file, chmods it to the required
2393 mode, then resets the umask. All the relevant calls to fopen() in the
2394 content scanning code have been changed to use this function.

2406 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2429PH/52 Two bugs concerned with error handling when the smtp transport is
2430 used in LMTP mode:
2431
2432 (i) Exim was not creating retry information for temporary errors given
2433 for individual recipients after the DATA command when the smtp transport
2434 was used in LMTP mode. This meant that they could be retried too
2435 frequently, and not timed out correctly.
2436
2437 (ii) Exim was setting the flag that allows error details to be returned
2438 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2439 recipients that were returned after the DATA command.
2440
2441PH/53 This is related to PH/52, but is more general: for any failing address,
2442 when detailed error information was permitted to be returned to the
2443 sender, but the error was temporary, then after the final timeout, only
2444 "retry timeout exceeded" was returned. Now it returns the full error as

2515PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2516 function verify_get_ident() calls ip_connect() to connect a socket, but
2517 if the "connect()" function timed out, ip_connect() used to close the
2518 socket. However, verify_get_ident() also closes the socket later, and in
2519 between Exim writes to the log, which may get opened at this point. When
2520 the socket was closed in ip_connect(), the log could get the same file
2521 descriptor number as the socket. This naturally causes chaos. The fix is
2522 not to close the socket in ip_connect(); the socket should be closed by
2523 the function that creates it. There was only one place in the code where
2524 this was missing, in the iplookup router, which I don't think anybody now
2525 uses, but I've fixed it anyway.

2549 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2551
2552 (3) Reset the variables that are obtained from the first argument of
2553 ${prvscheck and used in the second argument before leaving the code,
2554 because their memory is reclaimed, so using them afterwards may do
2555 silly things.
2556
2557 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2558 one (it's much easier than Tom thought :-).

2582 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2583 not being looked up in the rDNS to get a host name, Exim was showing the
2584 IP address twice in Received: lines, even though the IP addresses were
2585 identical. For example:
2586
2587 Received: from [1.2.3.4] (helo=[1.2.3.4])
2588
2589 However, if the real host name was known, it was omitting the HELO data
2590 if it matched the actual IP address. This has been tidied up so that it
2591 doesn't show the same IP address twice.

2624 also a typo: it was using "Auto_submitted" (underscore instead of
2625 hyphen). Since every message generated by Exim is necessarily in response
2626 to another message, thes have all been changed to:

2628 Auto-Submitted: auto-replied
2629
2630 in accordance with these statements in the RFC:

2683 addresses acquired from the DNS when checking that the found name did
2684 have the original IP as one of its addresses. Since any found IPv6
2685 addresses are likely to be in abbreviated form, the comparison could
2686 fail. Luckily, there already exists a function for doing the comparison
2687 by converting both addresses to binary, so now that is used instead of
2688 the text comparison.

2986 with the definition in sysexits.h (which is #included earlier).
2987 Fortunately, Exim does not actually use EX_OK. The code used to try to
2988 preserve the sysexits.h value, by assumimg that macro definitions were
2989 scanned for macro replacements. I have been disabused of this notion,
2990 so now the code just undefines EX_OK before #including unistd.h.

2994 write() function, the timeout was being re-applied to each part-write.
2995 This seems wrong - if the receiver was accepting one byte at a time it
2996 would take for ever. The timeout is now adjusted when this happens. It
2997 doesn't have to be particularly precise.

3148PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3149 aren't the modern standard, and it seems that some systems' include files
3150 don't always have them. Exim was already checking for some of the newer
3151 ones like T_AAAA, and defining it itself. I've added checks for all the
3152 record types that Exim uses.

3154PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3155 not automatically generating a new one, as it is supposed to. This
3156 prevented TLS from working. If the file did exist, but contained invalid
3157 data, a new version was generated, as expected. It was only the case of a
3158 non-existent file that was broken.

3169PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3170 the use of a port name that isn't defined in /etc/services) occurred, the
3171 message was deferred as in a normal delivery, and thus remained on the
3172 spool, instead of being failed because of the mua_wrapper setting. This
3173 is now fixed, and I tidied up some of the mua_wrapper messages at the
3174 same time.

3176SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3203PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3204 to test Sieve filters that use "vacation".
3205
3206PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3207 that changes the way the GnuTLS parameters are stored in the cache file.
3208 The new format can be generated externally. For backward compatibility,
3209 if the data in the cache doesn't make sense, Exim assumes it has read an
3210 old-format file, and it generates new data and writes a new file. This
3211 means that you can't go back to an older release without removing the
3212 file.
3213
3214PH/03 A redirect router that has both "unseen" and "one_time" set does not
3215 work if there are any delivery delays because "one_time" forces the
3216 parent to be marked "delivered", so its unseen clone is never tried
3217 again. For this reason, Exim now forbids the simultaneous setting of
3218 these two options.
3219
3220PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3221 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3222 entry if you want to know the details. The fix, however, neglected to
3223 consider the case when local delivery batching is involved. The test for
3224 "previously delivered" was not happening when checking to see if an
3225 address could be batched with a previous (undelivered) one; under
3226 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3227 address.

3228
3229PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3230 in its include files, and this causes problems building Exim.
3231
3232PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3233 header_syntax) but Exim was just ignoring anything given after a slash.
3234 In particular, this caused confusion with an attempt to use "verify =
3235 reverse_host_lookup/defer_ok". An error is now given when options are
3236 supplied for verify items that do not have them. (Maybe reverse_host_
3237 lookup should have a defer_ok option, but that's a different point.)
3238
3239PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3240 defined by RFC 821) to 2048, because there were problems with some AUTH
3241 commands, and RFC 1869 says the size should be increased for extended
3242 SMTP commands that take arguments.

3275 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3276 negation of where the condition IS allowed.

PH
3289PH/19 When an Exim process that is running as root has to create an Exim log
3290 file, it does so in a subprocess that runs as exim:exim so as to get the
3291 ownership right at creation (otherwise, other Exim processes might see
3292 the file with the wrong ownership). There was no test for failure of this
3293 fork() call, which would lead to the process getting stuck as it waited
3294 for a non-existent subprocess. Forks do occasionally fail when resources
3295 run out. I reviewed all the other calls to fork(); they all seem to check
3296 for failure.

PH
3298PH/20 When checking for unexpected SMTP input at connect time (before writing
3299 the banner), Exim was not dealing correctly with a non-positive return
3300 from the read() function. If the client had disconnected by this time,
3301 the result was a log entry for a synchronization error with an empty
3302 string after "input=" when read() returned zero. If read() returned -1
3303 (an event I could not check), uninitialized data bytes were printed.
3304 There were reports of junk text (parts of files, etc) appearing after
3305 "input=".

3314
c5ddb310
PH
3315PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3316 hadn't been configured. The fix is from Juergen Kreileder, who
3317 understands it better than I do:
3318
3319 "Here's what I see happening with three configured cyrus_sasl
3320 authenticators configured (plain, login, cram-md5):
3321
3322 On startup auth_cyrus_sasl_init() gets called for each of these.
3323 This means three calls to sasl_listmech() without a specified mech_list.
3324 => SASL tests which mechs of all available mechs actually work
3325 => three warnings about OTP not working
3326 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3327
3328 With the patch, sasl_listmech() also gets called three times. But now
3329 SASL's mech_list option is set to the server_mech specified in the the
3330 authenticator. Or in other words, the answer from sasl_listmech()
3331 gets limited to just the mech you're testing for (which is different
3332 for each call.)
3333 => the return list contains just 'plain' or 'login', 'cram-md5' or
3334 nothing depending on the value of ob->server_mech.
3335
3336 I've just tested the patch: Authentication still works fine,
3337 unavailable mechs specified in the exim configuration are still
3338 caught, and the auth.log warnings about OTP are gone."

3348PH/27 $acl_verify_message is now set immediately after the failure of a
3349 verification in an ACL, and so is available in subsequent modifiers. In

3351
3352 warn !verify = sender
3353 set acl_m0 = $acl_verify_message
