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.

160TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
161
162 When a queue runner is handling a message, Exim first routes the
163 recipient addresses, during which it prunes them based on the retry
164 hints database. After that it attempts to deliver the message to
165 any remaining recipients. It then updates the hints database using
166 the retry rules.
167
168 So if a recipient address works intermittently, it can get repeatedly
169 deferred at routing time. The retry hints record remains fresh so the
170 address never reaches the final cutoff time.
171
172 This is a fairly common occurrence when a user is bumping up against
173 their storage quota. Exim had some logic in its local delivery code
174 to deal with this. However it did not apply to per-recipient defers
175 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
176
1ddeb334
TF
177 This change adds a proper retry rule check during routing so that the
178 final cutoff time is checked against the message's age. We only do
179 this check if there is an address retry record and there is not a
180 domain retry record; this implies that previous attempts to handle
181 the address had the retry_use_local_parts option turned on. We use
182 this as an approximation for the destination being like a local
183 delivery, as in LMTP.
67bd1ab3
TF
184
185 I suspect this new check makes the old local delivery cutoff check
186 redundant, but I have not verified this so I left the code in place.

188TF/02 Correct gecos expansion when From: is a prefix of the username.
189
190 Test 0254 submits a message to Exim with the header
191
192 Resent-From: f
193
194 When I ran the test suite under the user fanf2, Exim expanded
195 the header to contain my full name, whereas it should have added
196 a Resent-Sender: header. It erroneously treats any prefix of the
197 username as equal to the username.
198
199 This change corrects that bug.

220JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
221 Server implementation by Todd Lyons, client by JH.
222 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
223 config variable "prdr_enable" controls whether the server
224 advertises the facility. If the client requests PRDR a new
225 acl_data_smtp_prdr ACL is called once for each recipient, after
226 the body content is received and before the acl_smtp_data ACL.
227 The client is controlled by bolth of: a hosts_try_prdr option
228 on the smtp transport, and the server advertisement.
229 Default client logging of deliveries and rejections involving
230 PRDR are flagged with the string "PRDR".

508TF/03 Make the exiwhat support code safe for signals. Previously Exim might
509 lock up or crash if it happened to be inside a call to libc when it
510 got a SIGUSR1 from exiwhat.
511
512 The SIGUSR1 handler appends the current process status to the process
513 log which is later printed by exiwhat. It used to use the general
514 purpose logging code to do this, but several functions it calls are
515 not safe for signals.
516
517 The new output code in the SIGUSR1 handler is specific to the process
518 log, and simple enough that it's easy to inspect for signal safety.
519 Removing some special cases also simplifies the general logging code.
520 Removing the spurious timestamps from the process log simplifies
521 exiwhat.

TF
523TF/04 Improved ratelimit ACL condition.
524
525 The /noupdate option has been deprecated in favour of /readonly which
526 has clearer semantics. The /leaky, /strict, and /readonly update modes
527 are mutually exclusive. The update mode is no longer included in the
528 database key; it just determines when the database is updated. (This
529 means that when you upgrde Exim will forget old rate measurements.)
530
531 Exim now checks that the per_* options are used with an update mode that
532 makes sense for the current ACL. For example, when Exim is processing a
533 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
534 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
535 must specify per_mail/readonly. If you omit the update mode it defaults to
536 /leaky where that makes sense (as before) or /readonly where required.
537
538 The /noupdate option is now undocumented but still supported for
539 backwards compatibility. It is equivalent to /readonly except that in
540 ACLs where /readonly is required you may specify /leaky/noupdate or
541 /strict/noupdate which are treated the same as /readonly.
542
543 A useful new feature is the /count= option. This is a generalization
544 of the per_byte option, so that you can measure the throughput of other
545 aggregate values. For example, the per_byte option is now equivalent
546 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
547
548 The per_rcpt option has been generalized using the /count= mechanism
549 (though it's more complicated than the per_byte equivalence). When it is
550 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
551 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
552 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
553 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
554 Note that using per_rcpt with a non-readonly update mode in more than
555 one ACL will cause the recipients to be double-counted. (The per_mail
556 and per_byte options don't have this problem.)
557
558 The handling of very low rates has changed slightly. If the computed rate
559 is less than the event's count (usually one) then this event is the first
560 after a long gap. In this case the rate is set to the same as this event's
561 count, so that the first message of a spam run is counted properly.
562
563 The major new feature is a mechanism for counting the rate of unique
564 events. The new per_addr option counts the number of different
565 recipients that someone has sent messages to in the last time period. It
566 behaves like per_rcpt if all the recipient addresses are different, but
567 duplicate recipient addresses do not increase the measured rate. Like
568 the /count= option this is a general mechanism, so the per_addr option
569 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
570 example, measure the rate that a client uses different sender addresses
571 with the options per_mail/unique=$sender_address. There are further
572 details in the main documentation.

1123 were called 'true' and it seems that C99 defines that as a reserved

1144PH/01 Another patch from the Sieve maintainer.
1145
6a3bceb1
PH
1146PH/02 When an IPv6 address is converted to a string for single-key lookup
1147 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1148 dots are used instead of colons so that keys in lsearch files need not
1149 contain colons. This was done some time before quoting was made available
1150 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1151 (notated using the quote facility) so as to distinguish them from IPv4
1152 keys. This meant that lookups for IP addresses in host lists did not work
1153 for iplsearch lookups.
1154
1155 This has been fixed by arranging for IPv6 addresses to be expressed with
1156 colons if the lookup type is iplsearch. This is not incompatible, because
1157 previously such lookups could never work.
1158
1159 The situation is now rather anomolous, since one *can* have colons in
1160 ordinary lsearch keys. However, making the change in all cases is
1161 incompatible and would probably break a number of configurations.

MH
1166MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1167 conversion specification without a maximum field width, thereby enabling
1168 a rogue spamd server to cause a buffer overflow. While nobody in their
1169 right mind would setup Exim to query an untrusted spamd server, an
1170 attacker that gains access to a server running spamd could potentially
1171 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1176MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1177 a directory entry by the name of the lookup key. Previously, if a
1178 symlink pointed to a non-existing file or a file in a directory that
1179 Exim lacked permissions to read, a lookup for a key matching that
1180 symlink would fail. Now it is enough that a matching directory entry
1181 exists, symlink or not. (Bugzilla 503.)

1364PH/29 SMTP synchronization checks are implemented when a command is read -
1365 there is a check that no more input is waiting when there shouldn't be

1367 some time before the response is written. In this time, more input might
1368 arrive, invalidly. So now there are extra checks after an ACL has run for
1369 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1370 pipelining has not been advertised.

1426 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1444 the response to the final '.' that terminates a message, but only in the
1445 case where the client has not sent further data following the '.'
1446 (unfortunately, this is allowed). However, in many cases there won't be
1447 any further data because there won't be any more messages to send. A call
1448 to select() can be used: if it shows that the input is "ready", there is
1449 either input waiting, or the socket has been closed. An attempt to read
1450 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1451 would have sent an OK response which the client would never have see.

1462PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1463 fixed by 4.65/MH/01 (is this a record?) are fixed:
1464
1465 (i) An empty string was always treated as zero by the numeric comparison
1466 operators. This behaviour has been restored.
1467
1468 (ii) It is documented that the numeric comparison operators always treat
1469 their arguments as decimal numbers. This was broken in that numbers
1470 starting with 0 were being interpreted as octal.
1471
1472 While fixing these problems I realized that there was another issue that
1473 hadn't been noticed. Values of message_size_limit (both the global option
1474 and the transport option) were treated as octal if they started with 0.
1475 The documentation was vague. These values are now always treated as
1476 decimal, and I will make that clear in the documentation.

2b1c6e3a
PH
1520PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1521 callout verification, Exim cached a "reject" for the entire domain. This
1522 is correct for most verifications, but it is not correct for a recipient
1523 verification with use_sender or use_postmaster set, because in that case
1524 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1525 case of MAIL FROM:<> rejection from other early rejections (e.g.
1526 rejection of HELO). When verifying a recipient using a non-null MAIL
1527 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1528 Whatever the result of the callout, the value of the domain cache is
1529 left unchanged (for any other kind of callout, getting as far as trying
1530 RCPT means that the domain itself is ok).

1566 probably the interface on which it is arriving) and not to the outgoing
1567 callout (which could be using a different interface). This has been
1568 changed to use the value of the helo_data option from the smtp transport
1569 instead - this is what is used when a message is actually being sent. If
1570 there is no remote transport (possible with a router that sets up host

7befa435 1574 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1575 (a) The code assumed that strncpy() returns a negative number on buffer
1576 overflow, which isn't the case. Replaced with Exim's string_format()
1577 function.
1578 (b) There were several signed/unsigned issues. I just did the minimum
1579 hacking in of casts. There is scope for a larger refactoring.
1580 (c) The code used strcasecmp() which is not a standard C function.
1581 Replaced with Exim's strcmpic() function.
1582 (d) The code set only $1; it now sets $auth1 as well.
1583 (e) A simple test gave the error "authentication client didn't specify

1591PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1592 address A is aliased to B and C, where B exists and C does not. Without
1593 -v the output is "A verified" because verification stops after a
1594 successful redirection if more than one address is generated. However,
1595 with -v the child addresses are also verified. Exim was outputting "A
1596 failed to verify" and then showing the successful verification for C,
1597 with its parentage. It now outputs "B failed to verify", showing B's
1598 parentage before showing the successful verification of C.

PH
1604PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1605 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1606 they consult the DNS. I had assumed they would set it the way they
1607 wanted; and indeed my experiments on Linux seem to show that in some
1608 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1609 To be on the safe side, however, I have now made the interface to
1610 host_find_byname() similar to host_find_bydns(), with an argument
1611 containing the DNS resolver options. The host_find_byname() function now
1612 sets these options at its start, just as host_find_bydns() does. The smtp
1613 transport options dns_qualify_single and dns_search_parents are passed to
1614 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1615 of host_find_byname() use the default settings of RES_DEFNAMES
1616 (qualify_single) but not RES_DNSRCH (search_parents).

1618PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1619 spool_read_header() do less string testing, by means of a preliminary
1620 switch on the second character of optional "-foo" lines. (This is
1621 overdue, caused by the large number of possibilities that now exist.
1622 Originally there were few.) While I was there, I also converted the
1623 str(n)cmp tests so they don't re-test the leading "-" and the first
1624 character, in the hope this might squeeze out yet more improvement.

PH
1626PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1627 flag allowing group syntax was set by the header_syntax check but not
1628 turned off, possible causing trouble later; (2) The flag was not being
1629 set at all for the header_verify test, causing "group"-style headers to
1630 be rejected. I have now set it in this case, and also caused header_
1631 verify to ignore an empty address taken from a group. While doing this, I
1632 came across some other cases where the code for allowing group syntax
1633 while scanning a header line wasn't quite right (mostly, not resetting
1634 the flag correctly in the right place). These bugs could have caused
1635 trouble for malformed header lines. I hope it is now all correct.

1637PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1640 but it didn't always do it. This confused somebody who was copying the
1641 code for some other use. I have removed all the tests.

PH
1643PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1644 feature that was used to support insecure browsers during the U.S. crypto
1645 embargo. It requires special client support, and Exim is probably the
1646 only MTA that supported it -- and would never use it because real RSA is
1647 always available. This code has been removed, because it had the bad
1648 effect of slowing Exim down by computing (never used) parameters for the
1649 RSA_EXPORT functionality.

1654 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1655 if the connection is using TLS or if the remote IP is the same as the
1656 local IP, and the "valid-client-cert option" if a client certificate has
1657 been verified.

1688
1689PH/30 Exim was sometimes attempting to deliver messages that had suffered
1690 address errors (4xx response to RCPT) over the same connection as other
1691 messages routed to the same hosts. Such deliveries are always "forced",
1692 so retry times are not inspected. This resulted in far too many retries
1693 for the affected addresses. The effect occurred only when there were more
1694 hosts than the hosts_max_try setting in the smtp transport when it had
1695 the 4xx errors. Those hosts that it had tried were not added to the list
1696 of hosts for which the message was waiting, so if all were tried, there
1697 was no problem. Two fixes have been applied:
1698
1699 (i) If there are any address or message errors in an SMTP delivery, none
1700 of the hosts (tried or untried) are now added to the list of hosts
1701 for which the message is waiting, so the message should not be a
1702 candidate for sending over the same connection that was used for a
1703 successful delivery of some other message. This seems entirely
1704 reasonable: after all the message is NOT "waiting for some host".
1705 This is so "obvious" that I'm not sure why it wasn't done
1706 previously. Hope I haven't missed anything, but it can't do any
1707 harm, as the worst effect is to miss an optimization.
1708
1709 (ii) If, despite (i), such a delivery is accidentally attempted, the
1710 routing retry time is respected, so at least it doesn't keep
1711 hammering the server.

1726PH/35 The error "getsockname() failed: connection reset by peer" was being
1727 written to the panic log as well as the main log, but it isn't really

1729 removed the panic log writing for the ECONNRESET error when getsockname()
1730 fails.
1731
48c7f9e2
PH
1732PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1733 runs only) independently of the message's sender address. This meant
1734 that, if the 4xx error was in fact related to the sender, a different
1735 message to the same recipient with a different sender could confuse
1736 things. In particualar, this can happen when sending to a greylisting
1737 server, but other circumstances could also provoke similar problems.
1738 I have changed the default so that the retry time for these errors is now
1739 based a combination of the sender and recipient addresses. This change
1740 can be overridden by setting address_retry_include_sender=false in the
1741 smtp transport.

2009PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2010 "Deny" causes Exim to reject the incoming connection with a 554 error.
2011 Unfortunately, if there is a major crisis, such as a disk failure,
2012 tcp-wrappers gives "deny", whereas what one would like would be some
2013 kind of temporary error. A kludge has been added to help with this.
2014 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2015 554 error is used if errno is still zero or contains ENOENT (which occurs
2016 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2017 451 error is used.

2051-----------------
2052
2053PH/01 The code for finding all the local interface addresses on a FreeBSD
2054 system running IPv6 was broken. This may well have applied to all BSD
2055 systems, as well as to others that have similar system calls. The broken
2056 code found IPv4 interfaces correctly, but gave incorrect values for the
2057 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2058 that it would not match correctly against @[] and not recognize the IPv6
2059 addresses as local.

2102 autoreply, Exim could try to deliver to a non-existent relative file

2122 non-existent - all you got was a failure to exec. I have made two
2123 changes:
2124
2125 (a) Failures to set uid/gid, the current directory, or a process leader
2126 in a subprocess such as that created by queryprogram now generate
2127 suitable debugging ouput when -d is set.
2128

2131 the subprocess without attempting to change uid/gid.

2136PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2137 additional section of a DNS packet that returns MX or SRV records.
2138 Instead, it always explicitly searches for A/AAAA records. This avoids
2139 major problems that occur when a DNS server includes only records of one
2140 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2141 fixed another bug: if SRV records were looked up and the corresponding
2142 address records were *not* found in the additional section, the port
2143 values from the SRV records were lost.

2145PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
2153PH/19 When calculating a retry time, Exim used to measure the "time since
2154 failure" by looking at the "first failed" field in the retry record. Now
2155 it does not use this if it is later than than the arrival time of the
2156 message. Instead it uses the arrival time. This makes for better
2157 behaviour in cases where some deliveries succeed, thus re-setting the
2158 "first failed" field. An example is a quota failure for a huge message
2159 when small messages continue to be delivered. Without this change, the
2160 "time since failure" will always be short, possible causing more frequent
2161 delivery attempts for the huge message than are intended.

PH
2258PH/42 The content-scanning code uses fopen() to create files in which to put
2259 message data. Previously it was not paying any attention to the mode of
2260 the files. Exim runs with umask(0) because the rest of the code creates
2261 files with open(), and sets the required mode explicitly. Thus, these
2262 files were ending up world-writeable. This was not a big issue, because,
2263 being within the spool directory, they were not world-accessible. I have
2264 created a function called modefopen, which takes an additional mode
2265 argument. It sets umask(777), creates the file, chmods it to the required
2266 mode, then resets the umask. All the relevant calls to fopen() in the

2304
2305 (i) Exim was not creating retry information for temporary errors given
2306 for individual recipients after the DATA command when the smtp transport
2307 was used in LMTP mode. This meant that they could be retried too
2308 frequently, and not timed out correctly.
2309
2310 (ii) Exim was setting the flag that allows error details to be returned
2311 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2312 recipients that were returned after the DATA command.
2313
2314PH/53 This is related to PH/52, but is more general: for any failing address,
2315 when detailed error information was permitted to be returned to the
2316 sender, but the error was temporary, then after the final timeout, only

2374PH/68 The bounce_return_message and bounce_return_body options were not being

2376 In particular, this applied to messages rejected by the ACL. This bug has
2377 been fixed. However, if bounce_return_message is true and bounce_return_
2378 body is false, the headers that are returned for a non-SMTP message
2379 include only those that have been read before the error was detected.

2388PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2389 function verify_get_ident() calls ip_connect() to connect a socket, but
2390 if the "connect()" function timed out, ip_connect() used to close the
2391 socket. However, verify_get_ident() also closes the socket later, and in
2392 between Exim writes to the log, which may get opened at this point. When
2393 the socket was closed in ip_connect(), the log could get the same file
2394 descriptor number as the socket. This naturally causes chaos. The fix is
2395 not to close the socket in ip_connect(); the socket should be closed by
2396 the function that creates it. There was only one place in the code where
2397 this was missing, in the iplookup router, which I don't think anybody now
2398 uses, but I've fixed it anyway.

2421
2422 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2423 string.
2424
2425 (3) Reset the variables that are obtained from the first argument of
2426 ${prvscheck and used in the second argument before leaving the code,
2427 because their memory is reclaimed, so using them afterwards may do
2428 silly things.
2429
2430 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2431 one (it's much easier than Tom thought :-).
2432

2454PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2455 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2456 not being looked up in the rDNS to get a host name, Exim was showing the
2457 IP address twice in Received: lines, even though the IP addresses were
2458 identical. For example:
2459
2460 Received: from [1.2.3.4] (helo=[1.2.3.4])
2461
2462 However, if the real host name was known, it was omitting the HELO data
2463 if it matched the actual IP address. This has been tidied up so that it
2464 doesn't show the same IP address twice.

2492
2493 Auto-submitted: auto-generated
2494
2495 in the messages that it generates (bounce messages and others, such as
2496 warnings). In the case of bounce messages for non-SMTP mesages, there was
2497 also a typo: it was using "Auto_submitted" (underscore instead of
2498 hyphen). Since every message generated by Exim is necessarily in response
2499 to another message, thes have all been changed to:
2500
2501 Auto-Submitted: auto-replied
2502
2503 in accordance with these statements in the RFC:
2504
2505 The auto-replied keyword:
2506
2507 - SHOULD be used on messages sent in direct response to another
2508 message by an automatic process,
2509

2553PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2555 the IP address, check_host() was doing a simple string comparison with
2556 addresses acquired from the DNS when checking that the found name did
2557 have the original IP as one of its addresses. Since any found IPv6
2558 addresses are likely to be in abbreviated form, the comparison could
2559 fail. Luckily, there already exists a function for doing the comparison
2560 by converting both addresses to binary, so now that is used instead of
2561 the text comparison.

2858PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2859 with the definition in sysexits.h (which is #included earlier).
2860 Fortunately, Exim does not actually use EX_OK. The code used to try to
2861 preserve the sysexits.h value, by assumimg that macro definitions were
2862 scanned for macro replacements. I have been disabused of this notion,
2863 so now the code just undefines EX_OK before #including unistd.h.

2868 This seems wrong - if the receiver was accepting one byte at a time it
2869 would take for ever. The timeout is now adjusted when this happens. It
2870 doesn't have to be particularly precise.

2946 case the guess is not the same as the compiled default, so the script
2947 suddenly stopped working when I started to use syslog. The patch checks

3078
3079PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3080 that changes the way the GnuTLS parameters are stored in the cache file.
3081 The new format can be generated externally. For backward compatibility,
3082 if the data in the cache doesn't make sense, Exim assumes it has read an
3083 old-format file, and it generates new data and writes a new file. This
3084 means that you can't go back to an older release without removing the
3085 file.
3086
3087PH/03 A redirect router that has both "unseen" and "one_time" set does not
3088 work if there are any delivery delays because "one_time" forces the
3089 parent to be marked "delivered", so its unseen clone is never tried
3090 again. For this reason, Exim now forbids the simultaneous setting of
3091 these two options.
3092
3093PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3094 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3095 entry if you want to know the details. The fix, however, neglected to
3096 consider the case when local delivery batching is involved. The test for
3097 "previously delivered" was not happening when checking to see if an
3098 address could be batched with a previous (undelivered) one; under
3099 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3100 address.

PH
3101
3102PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3105PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3106 header_syntax) but Exim was just ignoring anything given after a slash.
3107 In particular, this caused confusion with an attempt to use "verify =
3108 reverse_host_lookup/defer_ok". An error is now given when options are
3109 supplied for verify items that do not have them. (Maybe reverse_host_
3110 lookup should have a defer_ok option, but that's a different point.)
3111
3112PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3162PH/19 When an Exim process that is running as root has to create an Exim log
3163 file, it does so in a subprocess that runs as exim:exim so as to get the
3164 ownership right at creation (otherwise, other Exim processes might see
3165 the file with the wrong ownership). There was no test for failure of this
3166 fork() call, which would lead to the process getting stuck as it waited
3167 for a non-existent subprocess. Forks do occasionally fail when resources
3168 run out. I reviewed all the other calls to fork(); they all seem to check
3169 for failure.

3171PH/20 When checking for unexpected SMTP input at connect time (before writing
3172 the banner), Exim was not dealing correctly with a non-positive return
3173 from the read() function. If the client had disconnected by this time,
3174 the result was a log entry for a synchronization error with an empty
3175 string after "input=" when read() returned zero. If read() returned -1
3176 (an event I could not check), uninitialized data bytes were printed.
3177 There were reports of junk text (parts of files, etc) appearing after
3178 "input=".

PH
3188PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3189 hadn't been configured. The fix is from Juergen Kreileder, who
3190 understands it better than I do:
3191
3192 "Here's what I see happening with three configured cyrus_sasl
3193 authenticators configured (plain, login, cram-md5):
3194
3195 On startup auth_cyrus_sasl_init() gets called for each of these.
3196 This means three calls to sasl_listmech() without a specified mech_list.
3197 => SASL tests which mechs of all available mechs actually work
3198 => three warnings about OTP not working
3199 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3200
3201 With the patch, sasl_listmech() also gets called three times. But now
3202 SASL's mech_list option is set to the server_mech specified in the the
3203 authenticator. Or in other words, the answer from sasl_listmech()
3204 gets limited to just the mech you're testing for (which is different
3205 for each call.)
3206 => the return list contains just 'plain' or 'login', 'cram-md5' or
3207 nothing depending on the value of ob->server_mech.
3208
3209 I've just tested the patch: Authentication still works fine,
3210 unavailable mechs specified in the exim configuration are still
3211 caught, and the auth.log warnings about OTP are gone."

3243 . Two addresses routed to the same list of hosts;

3247 . Second host offers TLS and a TLS session is established;
3248 . Second host accepts second address.
3249 Exim incorrectly logged both deliveries with the TLS parameters (cipher

3251 address.

PH
3275PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3276 the grounds that routing the same address twice would always produce the
3277 same answer. This might have been true once, but it is certainly no
3278 longer true now. Routing a child address may depend on the previous
3279 routing that produced that child. Some complicated redirection strategies
3280 went wrong when messages had multiple recipients, and made Exim's
3281 behaviour dependent on the order in which the addresses were given.
3282
3283 I have moved the duplicate checking until after the routing is complete.
3284 Exim scans the addresses that are assigned to local and remote
3285 transports, and removes any duplicates. This means that more work will be
3286 done, as duplicates will always all be routed, but duplicates are
3287 presumably rare, so I don't expect this is of any significance.
3288
3289 For deliveries to pipes, files, and autoreplies, the duplicate checking
3290 still happens during the routing process, since they are not going to be
3291 routed further.

3293PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3294 It corrects a timeout issue with spamd. This is Ian's comment: "The
3295 background is that sometimes spamd either never reads data from a
3296 connection it has accepted, or it never writes response data. The exiscan
3297 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3298 blindly assumes that writes won't block so it may never time out."

3312PH/42 Exim no longer gives details of delivery errors for specific addresses in
3313 bounce and delay warning messages, except in certain special cases, which

3316 (a) An SMTP error message from a remote host;
3317 (b) A message specified in a :fail: redirection;
3318 (c) A message specified in a "fail" command in a system filter;
3319 (d) A message specified in a FAIL return from the queryprogram router;
3320 (e) A message specified by the cannot_route_message router option.
3321
3322 In these cases only, Exim does include the error details in bounce and
3323 warning messages. There are also a few cases where bland messages such
3324 as "unrouteable address" or "local delivery error" are given.

3332PH/45 In a pipe transport, although a timeout while waiting for the pipe
3333 process to complete was treated as a delivery failure, a timeout while
3334 writing the message to the pipe was logged, but erroneously treated as a
3335 successful delivery. Such timeouts include transport filter timeouts. For
3336 consistency with the overall process timeout, these timeouts are now
3337 treated as errors, giving rise to delivery failures by default. However,
3338 there is now a new Boolean option for the pipe transport called
3339 timeout_defer, which, if set TRUE, converts the failures into defers for
3340 both kinds of timeout. A transport filter timeout is now identified in
3341 the log output.

3350A note about Exim versions 4.44 and 4.50
3351----------------------------------------
3352
3353Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3354changes of various kinds. As a consequence, a big documentation update was
3355needed. This delayed the release for rather longer than seemed good, especially
3356in the light of a couple of (minor) security issues. Therefore, the changes
3357that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3358release. So 4.44 and 4.50 are in effect two different branches that both start
3359from 4.43.
3360
3361I have left the 4.50 change log unchanged; it contains all the changes since
33624.43. The change log for 4.44 is below; many of its items are identical to
3363those for 4.50. This seems to be the most sensible way to preserve the
3364historical information.
