21-----------------
22
23TF/01 Correctly close the server side of TLS when forking for delivery.
24
25 When a message was received over SMTP with TLS, Exim failed to clear up
26 the incoming connection properly after forking off the child process to
27 deliver the message. In some situations the subsequent outgoing
28 delivery connection happened to have the same fd number as the incoming
29 connection previously had. Exim would try to use TLS and fail, logging
30 a "Bad file descriptor" error.

276TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
277
278 When a queue runner is handling a message, Exim first routes the
279 recipient addresses, during which it prunes them based on the retry
280 hints database. After that it attempts to deliver the message to
281 any remaining recipients. It then updates the hints database using
282 the retry rules.
283
284 So if a recipient address works intermittently, it can get repeatedly
285 deferred at routing time. The retry hints record remains fresh so the
286 address never reaches the final cutoff time.
287
288 This is a fairly common occurrence when a user is bumping up against
289 their storage quota. Exim had some logic in its local delivery code
290 to deal with this. However it did not apply to per-recipient defers
291 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
292
1ddeb334
TF
293 This change adds a proper retry rule check during routing so that the
294 final cutoff time is checked against the message's age. We only do
295 this check if there is an address retry record and there is not a
296 domain retry record; this implies that previous attempts to handle
297 the address had the retry_use_local_parts option turned on. We use
298 this as an approximation for the destination being like a local
299 delivery, as in LMTP.
67bd1ab3
TF
300
301 I suspect this new check makes the old local delivery cutoff check
302 redundant, but I have not verified this so I left the code in place.

309
310 When I ran the test suite under the user fanf2, Exim expanded
311 the header to contain my full name, whereas it should have added
312 a Resent-Sender: header. It erroneously treats any prefix of the
313 username as equal to the username.

315 This change corrects that bug.

336JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
337 Server implementation by Todd Lyons, client by JH.
338 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
339 config variable "prdr_enable" controls whether the server
340 advertises the facility. If the client requests PRDR a new
341 acl_data_smtp_prdr ACL is called once for each recipient, after
342 the body content is received and before the acl_smtp_data ACL.
343 The client is controlled by bolth of: a hosts_try_prdr option
344 on the smtp transport, and the server advertisement.
345 Default client logging of deliveries and rejections involving
346 PRDR are flagged with the string "PRDR".

624TF/03 Make the exiwhat support code safe for signals. Previously Exim might
625 lock up or crash if it happened to be inside a call to libc when it
626 got a SIGUSR1 from exiwhat.
627
628 The SIGUSR1 handler appends the current process status to the process
629 log which is later printed by exiwhat. It used to use the general
630 purpose logging code to do this, but several functions it calls are
631 not safe for signals.
632
633 The new output code in the SIGUSR1 handler is specific to the process
634 log, and simple enough that it's easy to inspect for signal safety.
635 Removing some special cases also simplifies the general logging code.
636 Removing the spurious timestamps from the process log simplifies
637 exiwhat.
638
c99ce5c9
TF
639TF/04 Improved ratelimit ACL condition.
640
641 The /noupdate option has been deprecated in favour of /readonly which
642 has clearer semantics. The /leaky, /strict, and /readonly update modes
643 are mutually exclusive. The update mode is no longer included in the
644 database key; it just determines when the database is updated. (This
645 means that when you upgrde Exim will forget old rate measurements.)
646
647 Exim now checks that the per_* options are used with an update mode that
648 makes sense for the current ACL. For example, when Exim is processing a
649 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
650 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
651 must specify per_mail/readonly. If you omit the update mode it defaults to
652 /leaky where that makes sense (as before) or /readonly where required.
653
654 The /noupdate option is now undocumented but still supported for
655 backwards compatibility. It is equivalent to /readonly except that in
656 ACLs where /readonly is required you may specify /leaky/noupdate or
657 /strict/noupdate which are treated the same as /readonly.
658
659 A useful new feature is the /count= option. This is a generalization
660 of the per_byte option, so that you can measure the throughput of other
661 aggregate values. For example, the per_byte option is now equivalent
662 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
663
664 The per_rcpt option has been generalized using the /count= mechanism
665 (though it's more complicated than the per_byte equivalence). When it is
666 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
667 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
668 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
669 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
670 Note that using per_rcpt with a non-readonly update mode in more than
671 one ACL will cause the recipients to be double-counted. (The per_mail
672 and per_byte options don't have this problem.)
673
674 The handling of very low rates has changed slightly. If the computed rate
675 is less than the event's count (usually one) then this event is the first
676 after a long gap. In this case the rate is set to the same as this event's
677 count, so that the first message of a spam run is counted properly.
678
679 The major new feature is a mechanism for counting the rate of unique
680 events. The new per_addr option counts the number of different
681 recipients that someone has sent messages to in the last time period. It
682 behaves like per_rcpt if all the recipient addresses are different, but
683 duplicate recipient addresses do not increase the measured rate. Like
684 the /count= option this is a general mechanism, so the per_addr option
685 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
686 example, measure the rate that a client uses different sender addresses
687 with the options per_mail/unique=$sender_address. There are further
688 details in the main documentation.

1239 were called 'true' and it seems that C99 defines that as a reserved

1241 not include C99-style headers which use bools without triggering

1258-----------------
1259
1260PH/01 Another patch from the Sieve maintainer.
1261
6a3bceb1
PH
1262PH/02 When an IPv6 address is converted to a string for single-key lookup
1263 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1264 dots are used instead of colons so that keys in lsearch files need not
1265 contain colons. This was done some time before quoting was made available
1266 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1267 (notated using the quote facility) so as to distinguish them from IPv4
1268 keys. This meant that lookups for IP addresses in host lists did not work
1269 for iplsearch lookups.
1270
1271 This has been fixed by arranging for IPv6 addresses to be expressed with
1272 colons if the lookup type is iplsearch. This is not incompatible, because
1273 previously such lookups could never work.
1274
1275 The situation is now rather anomolous, since one *can* have colons in
1276 ordinary lsearch keys. However, making the change in all cases is
1277 incompatible and would probably break a number of configurations.

MH
1282MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1283 conversion specification without a maximum field width, thereby enabling
1284 a rogue spamd server to cause a buffer overflow. While nobody in their
1285 right mind would setup Exim to query an untrusted spamd server, an
1286 attacker that gains access to a server running spamd could potentially
1287 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1292MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1293 a directory entry by the name of the lookup key. Previously, if a
1294 symlink pointed to a non-existing file or a file in a directory that
1295 Exim lacked permissions to read, a lookup for a key matching that
1296 symlink would fail. Now it is enough that a matching directory entry
1297 exists, symlink or not. (Bugzilla 503.)

1374 if a client was not listed at all, or was listed with a value other than
1375 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

PH
1480PH/29 SMTP synchronization checks are implemented when a command is read -
1481 there is a check that no more input is waiting when there shouldn't be
1482 any. However, for some commands, a delay in an ACL can mean that it is
1483 some time before the response is written. In this time, more input might
1484 arrive, invalidly. So now there are extra checks after an ACL has run for
1485 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1486 pipelining has not been advertised.

PH
1498PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1500 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1501 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1502 was a macro that became an assignment, so it seemed to work. This has
1503 changed to a proper function call with a void return, hence the compile
1504 error. Exim's code has been fixed.

1532PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1533 whoever called Exim into the -H file. In the case of the daemon it was
1534 behaving confusingly. When first started, it used values for whoever
1535 started the daemon, but after a SIGHUP it used the Exim user (because it
1536 calls itself on a restart). I have changed the code so that it now always
1537 uses the Exim user.

1542 with PIPELINING or a stupid MUA), the error message that was given to the
1543 RCPT commands is included in the rejection of the DATA command. This is

PH
1560 the response to the final '.' that terminates a message, but only in the
1561 case where the client has not sent further data following the '.'
1562 (unfortunately, this is allowed). However, in many cases there won't be
1563 any further data because there won't be any more messages to send. A call
1564 to select() can be used: if it shows that the input is "ready", there is
1565 either input waiting, or the socket has been closed. An attempt to read
1566 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1567 would have sent an OK response which the client would never have see.

1568 This could lead to message repetition. This fix should cure that, at

1575Exim version 4.66
1576-----------------
1577
1578PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1579 fixed by 4.65/MH/01 (is this a record?) are fixed:
1580
1581 (i) An empty string was always treated as zero by the numeric comparison
1582 operators. This behaviour has been restored.
1583
1584 (ii) It is documented that the numeric comparison operators always treat
1585 their arguments as decimal numbers. This was broken in that numbers
1586 starting with 0 were being interpreted as octal.
1587
1588 While fixing these problems I realized that there was another issue that
1589 hadn't been noticed. Values of message_size_limit (both the global option
1590 and the transport option) were treated as octal if they started with 0.
1591 The documentation was vague. These values are now always treated as
1592 decimal, and I will make that clear in the documentation.

PH
1606PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1607 child addresses, Exim now panics and dies. Previously, because the count
1608 is held in a short int, deliveries were likely to be lost. As such a
1609 large number of recipients for a single message is ridiculous
1610 (performance will be very, very poor), I have chosen to impose a limit
1611 rather than extend the field.

1617TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1618 leftover -K file (the existence of which was triggered by #402).
1619 While we were at it, introduced process PID as part of the -K
1620 filename. This should rule out race conditions when creating
1621 these files.
1622
1623TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1624 processing considerably. Previous code took too long for large mails,
1625 triggering a timeout which in turn triggers #401.
1626
1627TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1628 in the DK code in transports.c. sendfile() is not really portable,
1629 hence the _LINUX specificness.

1631TF/01 In the add_headers option to the mail command in an Exim filter,

1633 header after the first one which had an odd number of characters
1634 in the field name.

2b1c6e3a
PH
1636PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1637 callout verification, Exim cached a "reject" for the entire domain. This
1638 is correct for most verifications, but it is not correct for a recipient
1639 verification with use_sender or use_postmaster set, because in that case
1640 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1641 case of MAIL FROM:<> rejection from other early rejections (e.g.
1642 rejection of HELO). When verifying a recipient using a non-null MAIL
1643 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1644 Whatever the result of the callout, the value of the domain cache is
1645 left unchanged (for any other kind of callout, getting as far as trying
1646 RCPT means that the domain itself is ok).

1680PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1681 hostname. This is wrong, because it relates to the incoming message (and
1682 probably the interface on which it is arriving) and not to the outgoing
1683 callout (which could be using a different interface). This has been
1684 changed to use the value of the helo_data option from the smtp transport
1685 instead - this is what is used when a message is actually being sent. If
1686 there is no remote transport (possible with a router that sets up host
1687 addresses), $smtp_active_hostname is used.

7befa435 1690 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1691 (a) The code assumed that strncpy() returns a negative number on buffer
1692 overflow, which isn't the case. Replaced with Exim's string_format()
1693 function.
1694 (b) There were several signed/unsigned issues. I just did the minimum
1695 hacking in of casts. There is scope for a larger refactoring.
1696 (c) The code used strcasecmp() which is not a standard C function.
1697 Replaced with Exim's strcmpic() function.
1698 (d) The code set only $1; it now sets $auth1 as well.
1699 (e) A simple test gave the error "authentication client didn't specify
1700 service in request". It would seem that Dovecot has changed its
1701 interface. Fortunately there's a specification; I followed it and
1702 changed what the client sends and it appears to be working now.

1707PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1708 address A is aliased to B and C, where B exists and C does not. Without
1709 -v the output is "A verified" because verification stops after a
1710 successful redirection if more than one address is generated. However,
1711 with -v the child addresses are also verified. Exim was outputting "A
1712 failed to verify" and then showing the successful verification for C,
1713 with its parentage. It now outputs "B failed to verify", showing B's
1714 parentage before showing the successful verification of C.

1717 look up a TXT record in a specific list after matching in a combined

1719
322050c2
PH
1720PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1721 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1722 they consult the DNS. I had assumed they would set it the way they
1723 wanted; and indeed my experiments on Linux seem to show that in some
1724 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1725 To be on the safe side, however, I have now made the interface to
1726 host_find_byname() similar to host_find_bydns(), with an argument
1727 containing the DNS resolver options. The host_find_byname() function now
1728 sets these options at its start, just as host_find_bydns() does. The smtp
1729 transport options dns_qualify_single and dns_search_parents are passed to
1730 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1731 of host_find_byname() use the default settings of RES_DEFNAMES
1732 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1734PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1735 spool_read_header() do less string testing, by means of a preliminary
1736 switch on the second character of optional "-foo" lines. (This is
1737 overdue, caused by the large number of possibilities that now exist.
1738 Originally there were few.) While I was there, I also converted the
1739 str(n)cmp tests so they don't re-test the leading "-" and the first
1740 character, in the hope this might squeeze out yet more improvement.

PH
1742PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1743 flag allowing group syntax was set by the header_syntax check but not
1744 turned off, possible causing trouble later; (2) The flag was not being
1745 set at all for the header_verify test, causing "group"-style headers to
1746 be rejected. I have now set it in this case, and also caused header_
1747 verify to ignore an empty address taken from a group. While doing this, I
1748 came across some other cases where the code for allowing group syntax
1749 while scanning a header line wasn't quite right (mostly, not resetting
1750 the flag correctly in the right place). These bugs could have caused
1751 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1753PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1754 with the "reply" argument non-NULL. The code, however (which originally
1755 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1756 but it didn't always do it. This confused somebody who was copying the
1757 code for some other use. I have removed all the tests.

411ef850
PH
1759PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1760 feature that was used to support insecure browsers during the U.S. crypto
1761 embargo. It requires special client support, and Exim is probably the
1762 only MTA that supported it -- and would never use it because real RSA is
1763 always available. This code has been removed, because it had the bad
1764 effect of slowing Exim down by computing (never used) parameters for the
1765 RSA_EXPORT functionality.
1766
7befa435
PH
1767PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1768 authenticator to fail if there's a tab character in the incoming data
1769 (there should never be unless someone is messing about, as it's supposed
1770 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1771 if the connection is using TLS or if the remote IP is the same as the
1772 local IP, and the "valid-client-cert option" if a client certificate has
1773 been verified.

1804
1805PH/30 Exim was sometimes attempting to deliver messages that had suffered
1806 address errors (4xx response to RCPT) over the same connection as other
1807 messages routed to the same hosts. Such deliveries are always "forced",
1808 so retry times are not inspected. This resulted in far too many retries
1809 for the affected addresses. The effect occurred only when there were more
1810 hosts than the hosts_max_try setting in the smtp transport when it had
1811 the 4xx errors. Those hosts that it had tried were not added to the list
1812 of hosts for which the message was waiting, so if all were tried, there
1813 was no problem. Two fixes have been applied:
1814
1815 (i) If there are any address or message errors in an SMTP delivery, none
1816 of the hosts (tried or untried) are now added to the list of hosts
1817 for which the message is waiting, so the message should not be a
1818 candidate for sending over the same connection that was used for a
1819 successful delivery of some other message. This seems entirely
1820 reasonable: after all the message is NOT "waiting for some host".
1821 This is so "obvious" that I'm not sure why it wasn't done
1822 previously. Hope I haven't missed anything, but it can't do any
1823 harm, as the worst effect is to miss an optimization.
1824
1825 (ii) If, despite (i), such a delivery is accidentally attempted, the
1826 routing retry time is respected, so at least it doesn't keep
1827 hammering the server.

PH
1842PH/35 The error "getsockname() failed: connection reset by peer" was being
1843 written to the panic log as well as the main log, but it isn't really
1844 panic-worthy as it just means the connection died rather early on. I have
1845 removed the panic log writing for the ECONNRESET error when getsockname()
1846 fails.
1847
48c7f9e2
PH
1848PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1849 runs only) independently of the message's sender address. This meant
1850 that, if the 4xx error was in fact related to the sender, a different
1851 message to the same recipient with a different sender could confuse
1852 things. In particualar, this can happen when sending to a greylisting
1853 server, but other circumstances could also provoke similar problems.
1854 I have changed the default so that the retry time for these errors is now
1855 based a combination of the sender and recipient addresses. This change
1856 can be overridden by setting address_retry_include_sender=false in the
1857 smtp transport.

2125PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2127 Unfortunately, if there is a major crisis, such as a disk failure,
2128 tcp-wrappers gives "deny", whereas what one would like would be some
2129 kind of temporary error. A kludge has been added to help with this.
2130 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2131 554 error is used if errno is still zero or contains ENOENT (which occurs
2132 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2133 451 error is used.

2169PH/01 The code for finding all the local interface addresses on a FreeBSD
2170 system running IPv6 was broken. This may well have applied to all BSD
2171 systems, as well as to others that have similar system calls. The broken
2172 code found IPv4 interfaces correctly, but gave incorrect values for the
2173 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2174 that it would not match correctly against @[] and not recognize the IPv6
2175 addresses as local.

2217 generate an autoreply, and therefore failed to obtain an address for the
2218 autoreply, Exim could try to deliver to a non-existent relative file
2219 name, causing unrelated and misleading errors. What now happens is that

2241 (a) Failures to set uid/gid, the current directory, or a process leader
2242 in a subprocess such as that created by queryprogram now generate
2243 suitable debugging ouput when -d is set.

2247 the subprocess without attempting to change uid/gid.

2253 additional section of a DNS packet that returns MX or SRV records.
2254 Instead, it always explicitly searches for A/AAAA records. This avoids
2255 major problems that occur when a DNS server includes only records of one
2256 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2257 fixed another bug: if SRV records were looked up and the corresponding
2258 address records were *not* found in the additional section, the port
2259 values from the SRV records were lost.

2261PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
2269PH/19 When calculating a retry time, Exim used to measure the "time since
2270 failure" by looking at the "first failed" field in the retry record. Now
2271 it does not use this if it is later than than the arrival time of the
2272 message. Instead it uses the arrival time. This makes for better
2273 behaviour in cases where some deliveries succeed, thus re-setting the
2274 "first failed" field. An example is a quota failure for a huge message
2275 when small messages continue to be delivered. Without this change, the
2276 "time since failure" will always be short, possible causing more frequent
2277 delivery attempts for the huge message than are intended.

PH
2374PH/42 The content-scanning code uses fopen() to create files in which to put
2375 message data. Previously it was not paying any attention to the mode of
2376 the files. Exim runs with umask(0) because the rest of the code creates
2377 files with open(), and sets the required mode explicitly. Thus, these
2378 files were ending up world-writeable. This was not a big issue, because,
2379 being within the spool directory, they were not world-accessible. I have
2380 created a function called modefopen, which takes an additional mode
2381 argument. It sets umask(777), creates the file, chmods it to the required
2382 mode, then resets the umask. All the relevant calls to fopen() in the
2383 content scanning code have been changed to use this function.

2394 received. Setting client_ignore_invalid_base64 true ignores these errors.
2395 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2396 they are received. Thus, the responses can be made to depend on the

2418PH/52 Two bugs concerned with error handling when the smtp transport is
2419 used in LMTP mode:
2420
2421 (i) Exim was not creating retry information for temporary errors given
2422 for individual recipients after the DATA command when the smtp transport
2423 was used in LMTP mode. This meant that they could be retried too
2424 frequently, and not timed out correctly.
2425
2426 (ii) Exim was setting the flag that allows error details to be returned
2427 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2428 recipients that were returned after the DATA command.
2429
2430PH/53 This is related to PH/52, but is more general: for any failing address,
2431 when detailed error information was permitted to be returned to the
2432 sender, but the error was temporary, then after the final timeout, only
2433 "retry timeout exceeded" was returned. Now it returns the full error as
2434 well as "retry timeout exceeded".

2504PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2505 function verify_get_ident() calls ip_connect() to connect a socket, but
2506 if the "connect()" function timed out, ip_connect() used to close the
2507 socket. However, verify_get_ident() also closes the socket later, and in
2508 between Exim writes to the log, which may get opened at this point. When
2509 the socket was closed in ip_connect(), the log could get the same file
2510 descriptor number as the socket. This naturally causes chaos. The fix is
2511 not to close the socket in ip_connect(); the socket should be closed by
2512 the function that creates it. There was only one place in the code where
2513 this was missing, in the iplookup router, which I don't think anybody now
2514 uses, but I've fixed it anyway.

2537
2538 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2540
2541 (3) Reset the variables that are obtained from the first argument of
2542 ${prvscheck and used in the second argument before leaving the code,
2543 because their memory is reclaimed, so using them afterwards may do
2544 silly things.
2545
2546 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2547 one (it's much easier than Tom thought :-).

2571 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2572 not being looked up in the rDNS to get a host name, Exim was showing the
2573 IP address twice in Received: lines, even though the IP addresses were
2574 identical. For example:
2575
2576 Received: from [1.2.3.4] (helo=[1.2.3.4])
2577
2578 However, if the real host name was known, it was omitting the HELO data
2579 if it matched the actual IP address. This has been tidied up so that it
2580 doesn't show the same IP address twice.

2611 in the messages that it generates (bounce messages and others, such as
2612 warnings). In the case of bounce messages for non-SMTP mesages, there was
2613 also a typo: it was using "Auto_submitted" (underscore instead of
2614 hyphen). Since every message generated by Exim is necessarily in response
2615 to another message, thes have all been changed to:
2616
2617 Auto-Submitted: auto-replied
2618
2619 in accordance with these statements in the RFC:
2620
2621 The auto-replied keyword:

2672 addresses acquired from the DNS when checking that the found name did
2673 have the original IP as one of its addresses. Since any found IPv6
2674 addresses are likely to be in abbreviated form, the comparison could
2675 fail. Luckily, there already exists a function for doing the comparison
2676 by converting both addresses to binary, so now that is used instead of
2677 the text comparison.

2761PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true

2975 with the definition in sysexits.h (which is #included earlier).
2976 Fortunately, Exim does not actually use EX_OK. The code used to try to
2977 preserve the sysexits.h value, by assumimg that macro definitions were
2978 scanned for macro replacements. I have been disabused of this notion,

2984 This seems wrong - if the receiver was accepting one byte at a time it

2986 doesn't have to be particularly precise.

3146 data, a new version was generated, as expected. It was only the case of a
3147 non-existent file that was broken.

3158PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3159 the use of a port name that isn't defined in /etc/services) occurred, the
3160 message was deferred as in a normal delivery, and thus remained on the
3161 spool, instead of being failed because of the mua_wrapper setting. This
3162 is now fixed, and I tidied up some of the mua_wrapper messages at the
3163 same time.

3165SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3192PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3193 to test Sieve filters that use "vacation".
3194
3195PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3196 that changes the way the GnuTLS parameters are stored in the cache file.
3197 The new format can be generated externally. For backward compatibility,
3198 if the data in the cache doesn't make sense, Exim assumes it has read an
3199 old-format file, and it generates new data and writes a new file. This
3200 means that you can't go back to an older release without removing the
3201 file.
3202
3203PH/03 A redirect router that has both "unseen" and "one_time" set does not
3204 work if there are any delivery delays because "one_time" forces the
3205 parent to be marked "delivered", so its unseen clone is never tried
3206 again. For this reason, Exim now forbids the simultaneous setting of
3207 these two options.
3208
3209PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3210 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3211 entry if you want to know the details. The fix, however, neglected to
3212 consider the case when local delivery batching is involved. The test for
3213 "previously delivered" was not happening when checking to see if an
3214 address could be batched with a previous (undelivered) one; under
3215 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3216 address.

PH
3217
3218PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3219 in its include files, and this causes problems building Exim.
3220
3221PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3222 header_syntax) but Exim was just ignoring anything given after a slash.
3223 In particular, this caused confusion with an attempt to use "verify =
3224 reverse_host_lookup/defer_ok". An error is now given when options are
3225 supplied for verify items that do not have them. (Maybe reverse_host_
3226 lookup should have a defer_ok option, but that's a different point.)
3227
3228PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3229 defined by RFC 821) to 2048, because there were problems with some AUTH
3230 commands, and RFC 1869 says the size should be increased for extended
3231 SMTP commands that take arguments.
3232
3233PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3234 Finch).

3264 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3265 negation of where the condition IS allowed.

PH
3278PH/19 When an Exim process that is running as root has to create an Exim log
3279 file, it does so in a subprocess that runs as exim:exim so as to get the
3280 ownership right at creation (otherwise, other Exim processes might see
3281 the file with the wrong ownership). There was no test for failure of this
3282 fork() call, which would lead to the process getting stuck as it waited
3283 for a non-existent subprocess. Forks do occasionally fail when resources
3284 run out. I reviewed all the other calls to fork(); they all seem to check
3285 for failure.

PH
3287PH/20 When checking for unexpected SMTP input at connect time (before writing
3288 the banner), Exim was not dealing correctly with a non-positive return
3289 from the read() function. If the client had disconnected by this time,
3290 the result was a log entry for a synchronization error with an empty
3291 string after "input=" when read() returned zero. If read() returned -1
3292 (an event I could not check), uninitialized data bytes were printed.
3293 There were reports of junk text (parts of files, etc) appearing after
3294 "input=".

3302 forgetting to use the resulting value; it was using the unexpanded value.
3303
c5ddb310
PH
3304PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3305 hadn't been configured. The fix is from Juergen Kreileder, who
3306 understands it better than I do:
3307
3308 "Here's what I see happening with three configured cyrus_sasl
3309 authenticators configured (plain, login, cram-md5):
3310
3311 On startup auth_cyrus_sasl_init() gets called for each of these.
3312 This means three calls to sasl_listmech() without a specified mech_list.
3313 => SASL tests which mechs of all available mechs actually work
3314 => three warnings about OTP not working
3315 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3316
3317 With the patch, sasl_listmech() also gets called three times. But now
3318 SASL's mech_list option is set to the server_mech specified in the the
3319 authenticator. Or in other words, the answer from sasl_listmech()
3320 gets limited to just the mech you're testing for (which is different
3321 for each call.)
3322 => the return list contains just 'plain' or 'login', 'cram-md5' or
3323 nothing depending on the value of ob->server_mech.
3324
3325 I've just tested the patch: Authentication still works fine,
3326 unavailable mechs specified in the exim configuration are still
3327 caught, and the auth.log warnings about OTP are gone."

3337PH/27 $acl_verify_message is now set immediately after the failure of a

3341 warn !verify = sender
3342 set acl_m0 = $acl_verify_message

3358PH/30 In these circumstances:
3359 . Two addresses routed to the same list of hosts;

3363 . Second host offers TLS and a TLS session is established;
3364 . Second host accepts second address.
3365 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3366 and peerdn, if requested) that were in fact used only for the second
3367 address.
