8TF/01 Correctly close the server side of TLS when forking for delivery.
9
10 When a message was received over SMTP with TLS, Exim failed to clear up
11 the incoming connection properly after forking off the child process to
12 deliver the message. In some situations the subsequent outgoing
13 delivery connection happened to have the same fd number as the incoming
14 connection previously had. Exim would try to use TLS and fail, logging
15 a "Bad file descriptor" error.

257TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
258
259 When a queue runner is handling a message, Exim first routes the
260 recipient addresses, during which it prunes them based on the retry
261 hints database. After that it attempts to deliver the message to
262 any remaining recipients. It then updates the hints database using
263 the retry rules.
264
265 So if a recipient address works intermittently, it can get repeatedly
266 deferred at routing time. The retry hints record remains fresh so the
267 address never reaches the final cutoff time.
268
269 This is a fairly common occurrence when a user is bumping up against
270 their storage quota. Exim had some logic in its local delivery code
271 to deal with this. However it did not apply to per-recipient defers
272 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
273
1ddeb334
TF
274 This change adds a proper retry rule check during routing so that the
275 final cutoff time is checked against the message's age. We only do
276 this check if there is an address retry record and there is not a
277 domain retry record; this implies that previous attempts to handle
278 the address had the retry_use_local_parts option turned on. We use
279 this as an approximation for the destination being like a local
280 delivery, as in LMTP.
67bd1ab3
TF
281
282 I suspect this new check makes the old local delivery cutoff check
283 redundant, but I have not verified this so I left the code in place.

287 Test 0254 submits a message to Exim with the header
288
289 Resent-From: f
290
291 When I ran the test suite under the user fanf2, Exim expanded
292 the header to contain my full name, whereas it should have added
293 a Resent-Sender: header. It erroneously treats any prefix of the
294 username as equal to the username.
295
296 This change corrects that bug.

317JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
318 Server implementation by Todd Lyons, client by JH.
319 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
320 config variable "prdr_enable" controls whether the server
321 advertises the facility. If the client requests PRDR a new
322 acl_data_smtp_prdr ACL is called once for each recipient, after
323 the body content is received and before the acl_smtp_data ACL.
324 The client is controlled by bolth of: a hosts_try_prdr option
325 on the smtp transport, and the server advertisement.
326 Default client logging of deliveries and rejections involving
327 PRDR are flagged with the string "PRDR".

605TF/03 Make the exiwhat support code safe for signals. Previously Exim might
606 lock up or crash if it happened to be inside a call to libc when it
607 got a SIGUSR1 from exiwhat.
608
609 The SIGUSR1 handler appends the current process status to the process
610 log which is later printed by exiwhat. It used to use the general
611 purpose logging code to do this, but several functions it calls are
612 not safe for signals.
613
614 The new output code in the SIGUSR1 handler is specific to the process
615 log, and simple enough that it's easy to inspect for signal safety.
616 Removing some special cases also simplifies the general logging code.
617 Removing the spurious timestamps from the process log simplifies
618 exiwhat.
619
c99ce5c9
TF
620TF/04 Improved ratelimit ACL condition.
621
622 The /noupdate option has been deprecated in favour of /readonly which
623 has clearer semantics. The /leaky, /strict, and /readonly update modes
624 are mutually exclusive. The update mode is no longer included in the
625 database key; it just determines when the database is updated. (This
626 means that when you upgrde Exim will forget old rate measurements.)
627
628 Exim now checks that the per_* options are used with an update mode that
629 makes sense for the current ACL. For example, when Exim is processing a
630 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
631 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
632 must specify per_mail/readonly. If you omit the update mode it defaults to
633 /leaky where that makes sense (as before) or /readonly where required.
634
635 The /noupdate option is now undocumented but still supported for
636 backwards compatibility. It is equivalent to /readonly except that in
637 ACLs where /readonly is required you may specify /leaky/noupdate or
638 /strict/noupdate which are treated the same as /readonly.
639
640 A useful new feature is the /count= option. This is a generalization
641 of the per_byte option, so that you can measure the throughput of other
642 aggregate values. For example, the per_byte option is now equivalent
643 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
644
645 The per_rcpt option has been generalized using the /count= mechanism
646 (though it's more complicated than the per_byte equivalence). When it is
647 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
648 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
649 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
650 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
651 Note that using per_rcpt with a non-readonly update mode in more than
652 one ACL will cause the recipients to be double-counted. (The per_mail
653 and per_byte options don't have this problem.)
654
655 The handling of very low rates has changed slightly. If the computed rate
656 is less than the event's count (usually one) then this event is the first
657 after a long gap. In this case the rate is set to the same as this event's
658 count, so that the first message of a spam run is counted properly.
659
660 The major new feature is a mechanism for counting the rate of unique
661 events. The new per_addr option counts the number of different
662 recipients that someone has sent messages to in the last time period. It
663 behaves like per_rcpt if all the recipient addresses are different, but
664 duplicate recipient addresses do not increase the measured rate. Like
665 the /count= option this is a general mechanism, so the per_addr option
666 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
667 example, measure the rate that a client uses different sender addresses
668 with the options per_mail/unique=$sender_address. There are further
669 details in the main documentation.

1220 were called 'true' and it seems that C99 defines that as a reserved

1222 not include C99-style headers which use bools without triggering

1241PH/01 Another patch from the Sieve maintainer.
1242
6a3bceb1
PH
1243PH/02 When an IPv6 address is converted to a string for single-key lookup
1244 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1245 dots are used instead of colons so that keys in lsearch files need not
1246 contain colons. This was done some time before quoting was made available
1247 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1248 (notated using the quote facility) so as to distinguish them from IPv4
1249 keys. This meant that lookups for IP addresses in host lists did not work
1250 for iplsearch lookups.
1251
1252 This has been fixed by arranging for IPv6 addresses to be expressed with
1253 colons if the lookup type is iplsearch. This is not incompatible, because
1254 previously such lookups could never work.
1255
1256 The situation is now rather anomolous, since one *can* have colons in
1257 ordinary lsearch keys. However, making the change in all cases is
1258 incompatible and would probably break a number of configurations.

MH
1263MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1264 conversion specification without a maximum field width, thereby enabling
1265 a rogue spamd server to cause a buffer overflow. While nobody in their
1266 right mind would setup Exim to query an untrusted spamd server, an
1267 attacker that gains access to a server running spamd could potentially
1268 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1273MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1274 a directory entry by the name of the lookup key. Previously, if a
1275 symlink pointed to a non-existing file or a file in a directory that
1276 Exim lacked permissions to read, a lookup for a key matching that
1277 symlink would fail. Now it is enough that a matching directory entry
1278 exists, symlink or not. (Bugzilla 503.)

1461PH/29 SMTP synchronization checks are implemented when a command is read -
1462 there is a check that no more input is waiting when there shouldn't be
1463 any. However, for some commands, a delay in an ACL can mean that it is
1464 some time before the response is written. In this time, more input might
1465 arrive, invalidly. So now there are extra checks after an ACL has run for
1466 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1467 pipelining has not been advertised.

1479PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

1481 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1482 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1483 was a macro that became an assignment, so it seemed to work. This has
1484 changed to a proper function call with a void return, hence the compile
1485 error. Exim's code has been fixed.

PH
1541 the response to the final '.' that terminates a message, but only in the
1542 case where the client has not sent further data following the '.'
1543 (unfortunately, this is allowed). However, in many cases there won't be
1544 any further data because there won't be any more messages to send. A call
1545 to select() can be used: if it shows that the input is "ready", there is
1546 either input waiting, or the socket has been closed. An attempt to read
1547 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1548 would have sent an OK response which the client would never have see.

1557-----------------
1558
1559PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1560 fixed by 4.65/MH/01 (is this a record?) are fixed:
1561
1562 (i) An empty string was always treated as zero by the numeric comparison
1563 operators. This behaviour has been restored.
1564
1565 (ii) It is documented that the numeric comparison operators always treat
1566 their arguments as decimal numbers. This was broken in that numbers
1567 starting with 0 were being interpreted as octal.
1568
1569 While fixing these problems I realized that there was another issue that
1570 hadn't been noticed. Values of message_size_limit (both the global option

1590 large number of recipients for a single message is ridiculous
1591 (performance will be very, very poor), I have chosen to impose a limit

1598TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1599 leftover -K file (the existence of which was triggered by #402).
1600 While we were at it, introduced process PID as part of the -K

1602 these files.

1608TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

1615 in the field name.

PH
1617PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1618 callout verification, Exim cached a "reject" for the entire domain. This
1619 is correct for most verifications, but it is not correct for a recipient
1620 verification with use_sender or use_postmaster set, because in that case
1621 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1622 case of MAIL FROM:<> rejection from other early rejections (e.g.
1623 rejection of HELO). When verifying a recipient using a non-null MAIL
1624 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1625 Whatever the result of the callout, the value of the domain cache is
1626 left unchanged (for any other kind of callout, getting as far as trying
1627 RCPT means that the domain itself is ok).

1661PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1663 probably the interface on which it is arriving) and not to the outgoing
1664 callout (which could be using a different interface). This has been
1665 changed to use the value of the helo_data option from the smtp transport
1666 instead - this is what is used when a message is actually being sent. If
1667 there is no remote transport (possible with a router that sets up host
1668 addresses), $smtp_active_hostname is used.

7befa435 1671 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1672 (a) The code assumed that strncpy() returns a negative number on buffer
1673 overflow, which isn't the case. Replaced with Exim's string_format()
1674 function.
1675 (b) There were several signed/unsigned issues. I just did the minimum
1676 hacking in of casts. There is scope for a larger refactoring.
1677 (c) The code used strcasecmp() which is not a standard C function.
1678 Replaced with Exim's strcmpic() function.
1679 (d) The code set only $1; it now sets $auth1 as well.
1680 (e) A simple test gave the error "authentication client didn't specify
1681 service in request". It would seem that Dovecot has changed its
1682 interface. Fortunately there's a specification; I followed it and
1683 changed what the client sends and it appears to be working now.

1689 address A is aliased to B and C, where B exists and C does not. Without
1690 -v the output is "A verified" because verification stops after a
1691 successful redirection if more than one address is generated. However,
1692 with -v the child addresses are also verified. Exim was outputting "A
1693 failed to verify" and then showing the successful verification for C,
1694 with its parentage. It now outputs "B failed to verify", showing B's
1695 parentage before showing the successful verification of C.

1700
322050c2
PH
1701PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1702 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1703 they consult the DNS. I had assumed they would set it the way they
1704 wanted; and indeed my experiments on Linux seem to show that in some
1705 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1706 To be on the safe side, however, I have now made the interface to
1707 host_find_byname() similar to host_find_bydns(), with an argument
1708 containing the DNS resolver options. The host_find_byname() function now
1709 sets these options at its start, just as host_find_bydns() does. The smtp
1710 transport options dns_qualify_single and dns_search_parents are passed to
1711 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1712 of host_find_byname() use the default settings of RES_DEFNAMES
1713 (qualify_single) but not RES_DNSRCH (search_parents).

1715PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1716 spool_read_header() do less string testing, by means of a preliminary
1717 switch on the second character of optional "-foo" lines. (This is
1718 overdue, caused by the large number of possibilities that now exist.
1719 Originally there were few.) While I was there, I also converted the
1720 str(n)cmp tests so they don't re-test the leading "-" and the first
1721 character, in the hope this might squeeze out yet more improvement.

PH
1723PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1724 flag allowing group syntax was set by the header_syntax check but not
1725 turned off, possible causing trouble later; (2) The flag was not being
1726 set at all for the header_verify test, causing "group"-style headers to
1727 be rejected. I have now set it in this case, and also caused header_
1728 verify to ignore an empty address taken from a group. While doing this, I
1729 came across some other cases where the code for allowing group syntax
1730 while scanning a header line wasn't quite right (mostly, not resetting
1731 the flag correctly in the right place). These bugs could have caused
1732 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1734PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1735 with the "reply" argument non-NULL. The code, however (which originally
1736 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1737 but it didn't always do it. This confused somebody who was copying the
1738 code for some other use. I have removed all the tests.

PH
1740PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1741 feature that was used to support insecure browsers during the U.S. crypto
1742 embargo. It requires special client support, and Exim is probably the
1743 only MTA that supported it -- and would never use it because real RSA is
1744 always available. This code has been removed, because it had the bad
1745 effect of slowing Exim down by computing (never used) parameters for the
1746 RSA_EXPORT functionality.

PH
1748PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1749 authenticator to fail if there's a tab character in the incoming data
1750 (there should never be unless someone is messing about, as it's supposed
1751 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1752 if the connection is using TLS or if the remote IP is the same as the
1753 local IP, and the "valid-client-cert option" if a client certificate has
1754 been verified.

1785
1786PH/30 Exim was sometimes attempting to deliver messages that had suffered
1787 address errors (4xx response to RCPT) over the same connection as other
1788 messages routed to the same hosts. Such deliveries are always "forced",
1789 so retry times are not inspected. This resulted in far too many retries
1790 for the affected addresses. The effect occurred only when there were more
1791 hosts than the hosts_max_try setting in the smtp transport when it had
1792 the 4xx errors. Those hosts that it had tried were not added to the list
1793 of hosts for which the message was waiting, so if all were tried, there
1794 was no problem. Two fixes have been applied:
1795
1796 (i) If there are any address or message errors in an SMTP delivery, none
1797 of the hosts (tried or untried) are now added to the list of hosts
1798 for which the message is waiting, so the message should not be a
1799 candidate for sending over the same connection that was used for a
1800 successful delivery of some other message. This seems entirely
1801 reasonable: after all the message is NOT "waiting for some host".
1802 This is so "obvious" that I'm not sure why it wasn't done
1803 previously. Hope I haven't missed anything, but it can't do any
1804 harm, as the worst effect is to miss an optimization.
1805
1806 (ii) If, despite (i), such a delivery is accidentally attempted, the
1807 routing retry time is respected, so at least it doesn't keep
1808 hammering the server.

1823PH/35 The error "getsockname() failed: connection reset by peer" was being
1824 written to the panic log as well as the main log, but it isn't really
1825 panic-worthy as it just means the connection died rather early on. I have
1826 removed the panic log writing for the ECONNRESET error when getsockname()
1827 fails.
1828
48c7f9e2
PH
1829PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1830 runs only) independently of the message's sender address. This meant
1831 that, if the 4xx error was in fact related to the sender, a different
1832 message to the same recipient with a different sender could confuse
1833 things. In particualar, this can happen when sending to a greylisting
1834 server, but other circumstances could also provoke similar problems.
1835 I have changed the default so that the retry time for these errors is now
1836 based a combination of the sender and recipient addresses. This change
1837 can be overridden by setting address_retry_include_sender=false in the
1838 smtp transport.

2109 tcp-wrappers gives "deny", whereas what one would like would be some
2110 kind of temporary error. A kludge has been added to help with this.
2111 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2112 554 error is used if errno is still zero or contains ENOENT (which occurs
2113 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2114 451 error is used.

2153 code found IPv4 interfaces correctly, but gave incorrect values for the
2154 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2155 that it would not match correctly against @[] and not recognize the IPv6
2156 addresses as local.

2199 autoreply, Exim could try to deliver to a non-existent relative file

2235 Instead, it always explicitly searches for A/AAAA records. This avoids
2236 major problems that occur when a DNS server includes only records of one
2237 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2238 fixed another bug: if SRV records were looked up and the corresponding
2239 address records were *not* found in the additional section, the port
2240 values from the SRV records were lost.

2242PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2250PH/19 When calculating a retry time, Exim used to measure the "time since
2251 failure" by looking at the "first failed" field in the retry record. Now
2252 it does not use this if it is later than than the arrival time of the
2253 message. Instead it uses the arrival time. This makes for better
2254 behaviour in cases where some deliveries succeed, thus re-setting the
2255 "first failed" field. An example is a quota failure for a huge message
2256 when small messages continue to be delivered. Without this change, the
2257 "time since failure" will always be short, possible causing more frequent
2258 delivery attempts for the huge message than are intended.

PH
2355PH/42 The content-scanning code uses fopen() to create files in which to put
2356 message data. Previously it was not paying any attention to the mode of
2357 the files. Exim runs with umask(0) because the rest of the code creates
2358 files with open(), and sets the required mode explicitly. Thus, these
2359 files were ending up world-writeable. This was not a big issue, because,
2360 being within the spool directory, they were not world-accessible. I have
2361 created a function called modefopen, which takes an additional mode
2362 argument. It sets umask(777), creates the file, chmods it to the required
2363 mode, then resets the umask. All the relevant calls to fopen() in the
2364 content scanning code have been changed to use this function.

2372PH/45 When the plaintext authenticator is running as a client, the server's
2373 challenges are checked to ensure they are valid base64 strings. By
2374 default, the authentication attempt is cancelled if an invalid string is
2375 received. Setting client_ignore_invalid_base64 true ignores these errors.
2376 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2377 they are received. Thus, the responses can be made to depend on the
2378 challenges. If an invalid string is ignored, an empty string is placed in
2379 the variable.

2399PH/52 Two bugs concerned with error handling when the smtp transport is
2400 used in LMTP mode:
2401
2402 (i) Exim was not creating retry information for temporary errors given
2403 for individual recipients after the DATA command when the smtp transport
2404 was used in LMTP mode. This meant that they could be retried too
2405 frequently, and not timed out correctly.
2406
2407 (ii) Exim was setting the flag that allows error details to be returned
2408 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2409 recipients that were returned after the DATA command.
2410
2411PH/53 This is related to PH/52, but is more general: for any failing address,
2412 when detailed error information was permitted to be returned to the
2413 sender, but the error was temporary, then after the final timeout, only
2414 "retry timeout exceeded" was returned. Now it returns the full error as
2415 well as "retry timeout exceeded".

2485PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2486 function verify_get_ident() calls ip_connect() to connect a socket, but
2487 if the "connect()" function timed out, ip_connect() used to close the
2488 socket. However, verify_get_ident() also closes the socket later, and in
2489 between Exim writes to the log, which may get opened at this point. When
2490 the socket was closed in ip_connect(), the log could get the same file
2491 descriptor number as the socket. This naturally causes chaos. The fix is
2492 not to close the socket in ip_connect(); the socket should be closed by
2493 the function that creates it. There was only one place in the code where
2494 this was missing, in the iplookup router, which I don't think anybody now
2495 uses, but I've fixed it anyway.

2518
2519 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2520 string.
2521
2522 (3) Reset the variables that are obtained from the first argument of
2523 ${prvscheck and used in the second argument before leaving the code,
2524 because their memory is reclaimed, so using them afterwards may do
2525 silly things.
2526
2527 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2528 one (it's much easier than Tom thought :-).

2551PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2552 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2553 not being looked up in the rDNS to get a host name, Exim was showing the
2554 IP address twice in Received: lines, even though the IP addresses were
2555 identical. For example:
2556
2557 Received: from [1.2.3.4] (helo=[1.2.3.4])
2558
2559 However, if the real host name was known, it was omitting the HELO data
2560 if it matched the actual IP address. This has been tidied up so that it
2561 doesn't show the same IP address twice.

2587PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2589
2590 Auto-submitted: auto-generated
2591
2592 in the messages that it generates (bounce messages and others, such as
2593 warnings). In the case of bounce messages for non-SMTP mesages, there was
2594 also a typo: it was using "Auto_submitted" (underscore instead of
2595 hyphen). Since every message generated by Exim is necessarily in response
2596 to another message, thes have all been changed to:
2597
2598 Auto-Submitted: auto-replied
2599
2600 in accordance with these statements in the RFC:
2601
2602 The auto-replied keyword:
2603
2604 - SHOULD be used on messages sent in direct response to another
2605 message by an automatic process,
2606

2653 addresses acquired from the DNS when checking that the found name did
2654 have the original IP as one of its addresses. Since any found IPv6
2655 addresses are likely to be in abbreviated form, the comparison could
2656 fail. Luckily, there already exists a function for doing the comparison
2657 by converting both addresses to binary, so now that is used instead of
2658 the text comparison.

2955PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2956 with the definition in sysexits.h (which is #included earlier).
2957 Fortunately, Exim does not actually use EX_OK. The code used to try to
2958 preserve the sysexits.h value, by assumimg that macro definitions were
2959 scanned for macro replacements. I have been disabused of this notion,
2960 so now the code just undefines EX_OK before #including unistd.h.

2965 This seems wrong - if the receiver was accepting one byte at a time it
2966 would take for ever. The timeout is now adjusted when this happens. It
2967 doesn't have to be particularly precise.

3147 the messages in a hash of arrays rather than using individual hashes.
3148 This is a bit cleaner and results in dramatic memory savings, albeit
3149 at a slight CPU cost.

3151SC/09 Eximstats: added the -show_rt<list> and the -show_dt<list> flags
3152 as requested by Marc Sherman.

3171TK/03 Fix ACL "regex" condition not being available in MIME ACL.

3173PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3174 to test Sieve filters that use "vacation".
3175
3176PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3177 that changes the way the GnuTLS parameters are stored in the cache file.
3178 The new format can be generated externally. For backward compatibility,
3179 if the data in the cache doesn't make sense, Exim assumes it has read an
3180 old-format file, and it generates new data and writes a new file. This
3181 means that you can't go back to an older release without removing the
3182 file.
3183
3184PH/03 A redirect router that has both "unseen" and "one_time" set does not
3185 work if there are any delivery delays because "one_time" forces the
3186 parent to be marked "delivered", so its unseen clone is never tried
3187 again. For this reason, Exim now forbids the simultaneous setting of
3188 these two options.
3189
3190PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3191 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3192 entry if you want to know the details. The fix, however, neglected to
3193 consider the case when local delivery batching is involved. The test for
3194 "previously delivered" was not happening when checking to see if an
3195 address could be batched with a previous (undelivered) one; under
3196 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3197 address.
1a46a8c5
PH
3198
3199PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3200 in its include files, and this causes problems building Exim.
3201
3202PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3203 header_syntax) but Exim was just ignoring anything given after a slash.
3204 In particular, this caused confusion with an attempt to use "verify =
3205 reverse_host_lookup/defer_ok". An error is now given when options are
3206 supplied for verify items that do not have them. (Maybe reverse_host_
3207 lookup should have a defer_ok option, but that's a different point.)
3208
3209PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3210 defined by RFC 821) to 2048, because there were problems with some AUTH
3211 commands, and RFC 1869 says the size should be increased for extended
3212 SMTP commands that take arguments.
3213
3214PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3215 Finch).
3216
3217PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an

3223 PH/42 below, there is no longer a chance of it appearing in a bounce

3242PH/15 Further to TK/02 and TK/03 above, tidied up the tables of what conditions
3243 and controls are allowed in which ACLs. There were a couple of minor
3244 errors. Some of the entries in the conditions table (which is a table of
3245 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3246 negation of where the condition IS allowed.

3250PH/17 The API for radiusclient changed at release 0.4.0. Unfortunately, the
3251 header file does not have a version number, so I've had to invent a new
3252 value for RADIUS_LIB_TYPE, namely "RADIUSCLIENTNEW" to request the new
3253 API. The code is untested by me (my Linux distribution still has 0.3.2 of
3254 radiusclient), but it was contributed by a Radius user.

PH
3259PH/19 When an Exim process that is running as root has to create an Exim log
3260 file, it does so in a subprocess that runs as exim:exim so as to get the
3261 ownership right at creation (otherwise, other Exim processes might see
3262 the file with the wrong ownership). There was no test for failure of this
3263 fork() call, which would lead to the process getting stuck as it waited
3264 for a non-existent subprocess. Forks do occasionally fail when resources
3265 run out. I reviewed all the other calls to fork(); they all seem to check
3266 for failure.
3267
f9b9210e
PH
3268PH/20 When checking for unexpected SMTP input at connect time (before writing
3269 the banner), Exim was not dealing correctly with a non-positive return
3270 from the read() function. If the client had disconnected by this time,
3271 the result was a log entry for a synchronization error with an empty
3272 string after "input=" when read() returned zero. If read() returned -1
3273 (an event I could not check), uninitialized data bytes were printed.
3274 There were reports of junk text (parts of files, etc) appearing after
3275 "input=".

3282PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then
3283 forgetting to use the resulting value; it was using the unexpanded value.
3284
c5ddb310
PH
3285PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3286 hadn't been configured. The fix is from Juergen Kreileder, who
3287 understands it better than I do:
3288
3289 "Here's what I see happening with three configured cyrus_sasl
3290 authenticators configured (plain, login, cram-md5):
3291
3292 On startup auth_cyrus_sasl_init() gets called for each of these.
3293 This means three calls to sasl_listmech() without a specified mech_list.
3294 => SASL tests which mechs of all available mechs actually work
3295 => three warnings about OTP not working
3296 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3297
3298 With the patch, sasl_listmech() also gets called three times. But now
3299 SASL's mech_list option is set to the server_mech specified in the the
3300 authenticator. Or in other words, the answer from sasl_listmech()
3301 gets limited to just the mech you're testing for (which is different
3302 for each call.)
3303 => the return list contains just 'plain' or 'login', 'cram-md5' or
3304 nothing depending on the value of ob->server_mech.
3305
3306 I've just tested the patch: Authentication still works fine,
3307 unavailable mechs specified in the exim configuration are still
3308 caught, and the auth.log warnings about OTP are gone."

PH
3318PH/27 $acl_verify_message is now set immediately after the failure of a
3319 verification in an ACL, and so is available in subsequent modifiers. In
3320 particular, the message can be preserved by coding like this:
3321
3322 warn !verify = sender
3323 set acl_m0 = $acl_verify_message
3324
3325 Previously, $acl_verify_message was set only while expanding "message"
3326 and "log_message" when a very denied access.

PH
3339PH/30 In these circumstances:
3340 . Two addresses routed to the same list of hosts;
3341 . First host does not offer TLS;
3342 . First host accepts first address;
3343 . First host gives temporary error to second address;
3344 . Second host offers TLS and a TLS session is established;
3345 . Second host accepts second address.
3346 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3347 and peerdn, if requested) that were in fact used only for the second
3348 address.

3350PH/31 When doing a callout as part of verifying an address, Exim was not paying
3351 attention to any local part prefix or suffix that was matched by the

3353 does for delivery: the affixes are removed from the local part unless
3354 rcpt_include_affixes is set on the transport.
