6-----------------
7
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.

TF
173TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
174
175 When a queue runner is handling a message, Exim first routes the
176 recipient addresses, during which it prunes them based on the retry
177 hints database. After that it attempts to deliver the message to
178 any remaining recipients. It then updates the hints database using
179 the retry rules.
180
181 So if a recipient address works intermittently, it can get repeatedly
182 deferred at routing time. The retry hints record remains fresh so the
183 address never reaches the final cutoff time.
184
185 This is a fairly common occurrence when a user is bumping up against
186 their storage quota. Exim had some logic in its local delivery code
187 to deal with this. However it did not apply to per-recipient defers
188 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
189
1ddeb334
TF
190 This change adds a proper retry rule check during routing so that the
191 final cutoff time is checked against the message's age. We only do
192 this check if there is an address retry record and there is not a
193 domain retry record; this implies that previous attempts to handle
194 the address had the retry_use_local_parts option turned on. We use
195 this as an approximation for the destination being like a local
196 delivery, as in LMTP.
67bd1ab3
TF
197
198 I suspect this new check makes the old local delivery cutoff check
199 redundant, but I have not verified this so I left the code in place.

201TF/02 Correct gecos expansion when From: is a prefix of the username.
202
203 Test 0254 submits a message to Exim with the header
204
205 Resent-From: f
206
207 When I ran the test suite under the user fanf2, Exim expanded
208 the header to contain my full name, whereas it should have added
209 a Resent-Sender: header. It erroneously treats any prefix of the
210 username as equal to the username.
211
212 This change corrects that bug.

233JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
234 Server implementation by Todd Lyons, client by JH.
235 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
236 config variable "prdr_enable" controls whether the server
237 advertises the facility. If the client requests PRDR a new
238 acl_data_smtp_prdr ACL is called once for each recipient, after
239 the body content is received and before the acl_smtp_data ACL.
240 The client is controlled by bolth of: a hosts_try_prdr option
241 on the smtp transport, and the server advertisement.
242 Default client logging of deliveries and rejections involving
243 PRDR are flagged with the string "PRDR".

253 This is now consistent with GnuTLS, and is now documented: the
254 previous undocumented portable approach to treating the option as

256 an empty string is now equivalent.

521TF/03 Make the exiwhat support code safe for signals. Previously Exim might
522 lock up or crash if it happened to be inside a call to libc when it
523 got a SIGUSR1 from exiwhat.
524
525 The SIGUSR1 handler appends the current process status to the process
526 log which is later printed by exiwhat. It used to use the general
527 purpose logging code to do this, but several functions it calls are
528 not safe for signals.
529
530 The new output code in the SIGUSR1 handler is specific to the process
531 log, and simple enough that it's easy to inspect for signal safety.
532 Removing some special cases also simplifies the general logging code.
533 Removing the spurious timestamps from the process log simplifies
534 exiwhat.

TF
536TF/04 Improved ratelimit ACL condition.
537
538 The /noupdate option has been deprecated in favour of /readonly which
539 has clearer semantics. The /leaky, /strict, and /readonly update modes
540 are mutually exclusive. The update mode is no longer included in the
541 database key; it just determines when the database is updated. (This
542 means that when you upgrde Exim will forget old rate measurements.)
543
544 Exim now checks that the per_* options are used with an update mode that
545 makes sense for the current ACL. For example, when Exim is processing a
546 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
547 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
548 must specify per_mail/readonly. If you omit the update mode it defaults to
549 /leaky where that makes sense (as before) or /readonly where required.
550
551 The /noupdate option is now undocumented but still supported for
552 backwards compatibility. It is equivalent to /readonly except that in
553 ACLs where /readonly is required you may specify /leaky/noupdate or
554 /strict/noupdate which are treated the same as /readonly.
555
556 A useful new feature is the /count= option. This is a generalization
557 of the per_byte option, so that you can measure the throughput of other
558 aggregate values. For example, the per_byte option is now equivalent
559 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
560
561 The per_rcpt option has been generalized using the /count= mechanism
562 (though it's more complicated than the per_byte equivalence). When it is
563 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
564 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
565 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
566 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
567 Note that using per_rcpt with a non-readonly update mode in more than
568 one ACL will cause the recipients to be double-counted. (The per_mail
569 and per_byte options don't have this problem.)
570
571 The handling of very low rates has changed slightly. If the computed rate
572 is less than the event's count (usually one) then this event is the first
573 after a long gap. In this case the rate is set to the same as this event's
574 count, so that the first message of a spam run is counted properly.
575
576 The major new feature is a mechanism for counting the rate of unique
577 events. The new per_addr option counts the number of different
578 recipients that someone has sent messages to in the last time period. It
579 behaves like per_rcpt if all the recipient addresses are different, but
580 duplicate recipient addresses do not increase the measured rate. Like
581 the /count= option this is a general mechanism, so the per_addr option
582 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
583 example, measure the rate that a client uses different sender addresses
584 with the options per_mail/unique=$sender_address. There are further
585 details in the main documentation.

1157PH/01 Another patch from the Sieve maintainer.
1158
6a3bceb1
PH
1159PH/02 When an IPv6 address is converted to a string for single-key lookup
1160 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1161 dots are used instead of colons so that keys in lsearch files need not
1162 contain colons. This was done some time before quoting was made available
1163 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1164 (notated using the quote facility) so as to distinguish them from IPv4
1165 keys. This meant that lookups for IP addresses in host lists did not work
1166 for iplsearch lookups.
1167
1168 This has been fixed by arranging for IPv6 addresses to be expressed with
1169 colons if the lookup type is iplsearch. This is not incompatible, because
1170 previously such lookups could never work.
1171
1172 The situation is now rather anomolous, since one *can* have colons in
1173 ordinary lsearch keys. However, making the change in all cases is
1174 incompatible and would probably break a number of configurations.

1179MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1180 conversion specification without a maximum field width, thereby enabling
1181 a rogue spamd server to cause a buffer overflow. While nobody in their
1182 right mind would setup Exim to query an untrusted spamd server, an
1183 attacker that gains access to a server running spamd could potentially
1184 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1189MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1190 a directory entry by the name of the lookup key. Previously, if a
1191 symlink pointed to a non-existing file or a file in a directory that
1192 Exim lacked permissions to read, a lookup for a key matching that
1193 symlink would fail. Now it is enough that a matching directory entry
1194 exists, symlink or not. (Bugzilla 503.)

1377PH/29 SMTP synchronization checks are implemented when a command is read -
1378 there is a check that no more input is waiting when there shouldn't be

1380 some time before the response is written. In this time, more input might
1381 arrive, invalidly. So now there are extra checks after an ACL has run for
1382 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1383 pipelining has not been advertised.

1398 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1399 was a macro that became an assignment, so it seemed to work. This has

1439 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1457 the response to the final '.' that terminates a message, but only in the
1458 case where the client has not sent further data following the '.'
1459 (unfortunately, this is allowed). However, in many cases there won't be
1460 any further data because there won't be any more messages to send. A call
1461 to select() can be used: if it shows that the input is "ready", there is
1462 either input waiting, or the socket has been closed. An attempt to read
1463 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1464 would have sent an OK response which the client would never have see.

1475PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1476 fixed by 4.65/MH/01 (is this a record?) are fixed:
1477
1478 (i) An empty string was always treated as zero by the numeric comparison
1479 operators. This behaviour has been restored.
1480
1481 (ii) It is documented that the numeric comparison operators always treat
1482 their arguments as decimal numbers. This was broken in that numbers
1483 starting with 0 were being interpreted as octal.
1484
1485 While fixing these problems I realized that there was another issue that
1486 hadn't been noticed. Values of message_size_limit (both the global option
1487 and the transport option) were treated as octal if they started with 0.
1488 The documentation was vague. These values are now always treated as
1489 decimal, and I will make that clear in the documentation.

2b1c6e3a
PH
1533PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1534 callout verification, Exim cached a "reject" for the entire domain. This
1535 is correct for most verifications, but it is not correct for a recipient
1536 verification with use_sender or use_postmaster set, because in that case
1537 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1538 case of MAIL FROM:<> rejection from other early rejections (e.g.
1539 rejection of HELO). When verifying a recipient using a non-null MAIL
1540 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1541 Whatever the result of the callout, the value of the domain cache is
1542 left unchanged (for any other kind of callout, getting as far as trying
1543 RCPT means that the domain itself is ok).

1579 probably the interface on which it is arriving) and not to the outgoing
1580 callout (which could be using a different interface). This has been
1581 changed to use the value of the helo_data option from the smtp transport
1582 instead - this is what is used when a message is actually being sent. If
1583 there is no remote transport (possible with a router that sets up host

14aa5a05 1586PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1587 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1588 (a) The code assumed that strncpy() returns a negative number on buffer
1589 overflow, which isn't the case. Replaced with Exim's string_format()
1590 function.
1591 (b) There were several signed/unsigned issues. I just did the minimum
1592 hacking in of casts. There is scope for a larger refactoring.
1593 (c) The code used strcasecmp() which is not a standard C function.
1594 Replaced with Exim's strcmpic() function.
1595 (d) The code set only $1; it now sets $auth1 as well.
1596 (e) A simple test gave the error "authentication client didn't specify
1597 service in request". It would seem that Dovecot has changed its
1598 interface. Fortunately there's a specification; I followed it and
1599 changed what the client sends and it appears to be working now.

e6f6568e
PH
1604PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1605 address A is aliased to B and C, where B exists and C does not. Without
1606 -v the output is "A verified" because verification stops after a
1607 successful redirection if more than one address is generated. However,
1608 with -v the child addresses are also verified. Exim was outputting "A
1609 failed to verify" and then showing the successful verification for C,
1610 with its parentage. It now outputs "B failed to verify", showing B's
1611 parentage before showing the successful verification of C.

PH
1613PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1614 look up a TXT record in a specific list after matching in a combined
1615 list.
1616
322050c2
PH
1617PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1618 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1619 they consult the DNS. I had assumed they would set it the way they
1620 wanted; and indeed my experiments on Linux seem to show that in some
1621 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1622 To be on the safe side, however, I have now made the interface to
1623 host_find_byname() similar to host_find_bydns(), with an argument
1624 containing the DNS resolver options. The host_find_byname() function now
1625 sets these options at its start, just as host_find_bydns() does. The smtp
1626 transport options dns_qualify_single and dns_search_parents are passed to
1627 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1628 of host_find_byname() use the default settings of RES_DEFNAMES
1629 (qualify_single) but not RES_DNSRCH (search_parents).
1630

PH
1631PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1632 spool_read_header() do less string testing, by means of a preliminary
1633 switch on the second character of optional "-foo" lines. (This is
1634 overdue, caused by the large number of possibilities that now exist.
1635 Originally there were few.) While I was there, I also converted the
1636 str(n)cmp tests so they don't re-test the leading "-" and the first
1637 character, in the hope this might squeeze out yet more improvement.
1638
1eccaa59
PH
1639PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1640 flag allowing group syntax was set by the header_syntax check but not
1641 turned off, possible causing trouble later; (2) The flag was not being
1642 set at all for the header_verify test, causing "group"-style headers to
1643 be rejected. I have now set it in this case, and also caused header_
1644 verify to ignore an empty address taken from a group. While doing this, I
1645 came across some other cases where the code for allowing group syntax
1646 while scanning a header line wasn't quite right (mostly, not resetting
1647 the flag correctly in the right place). These bugs could have caused
1648 trouble for malformed header lines. I hope it is now all correct.
1649
602e59e5
PH
1650PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1651 with the "reply" argument non-NULL. The code, however (which originally
1652 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1653 but it didn't always do it. This confused somebody who was copying the
1654 code for some other use. I have removed all the tests.
1655
411ef850
PH
1656PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1657 feature that was used to support insecure browsers during the U.S. crypto
1658 embargo. It requires special client support, and Exim is probably the
1659 only MTA that supported it -- and would never use it because real RSA is
1660 always available. This code has been removed, because it had the bad
1661 effect of slowing Exim down by computing (never used) parameters for the
1662 RSA_EXPORT functionality.
1663
7befa435
PH
1664PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1665 authenticator to fail if there's a tab character in the incoming data
1666 (there should never be unless someone is messing about, as it's supposed
1667 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1668 if the connection is using TLS or if the remote IP is the same as the
1669 local IP, and the "valid-client-cert option" if a client certificate has
1670 been verified.
1671
48da4259 1672PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
1701
1702PH/30 Exim was sometimes attempting to deliver messages that had suffered
1703 address errors (4xx response to RCPT) over the same connection as other
1704 messages routed to the same hosts. Such deliveries are always "forced",
1705 so retry times are not inspected. This resulted in far too many retries
1706 for the affected addresses. The effect occurred only when there were more
1707 hosts than the hosts_max_try setting in the smtp transport when it had
1708 the 4xx errors. Those hosts that it had tried were not added to the list
1709 of hosts for which the message was waiting, so if all were tried, there
1710 was no problem. Two fixes have been applied:
1711
1712 (i) If there are any address or message errors in an SMTP delivery, none
1713 of the hosts (tried or untried) are now added to the list of hosts
1714 for which the message is waiting, so the message should not be a
1715 candidate for sending over the same connection that was used for a
1716 successful delivery of some other message. This seems entirely
1717 reasonable: after all the message is NOT "waiting for some host".
1718 This is so "obvious" that I'm not sure why it wasn't done
1719 previously. Hope I haven't missed anything, but it can't do any
1720 harm, as the worst effect is to miss an optimization.
1721
1722 (ii) If, despite (i), such a delivery is accidentally attempted, the
1723 routing retry time is respected, so at least it doesn't keep
1724 hammering the server.

PH
1739PH/35 The error "getsockname() failed: connection reset by peer" was being
1740 written to the panic log as well as the main log, but it isn't really
1741 panic-worthy as it just means the connection died rather early on. I have
1742 removed the panic log writing for the ECONNRESET error when getsockname()
1743 fails.
1744
48c7f9e2
PH
1745PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1746 runs only) independently of the message's sender address. This meant
1747 that, if the 4xx error was in fact related to the sender, a different
1748 message to the same recipient with a different sender could confuse
1749 things. In particualar, this can happen when sending to a greylisting
1750 server, but other circumstances could also provoke similar problems.
1751 I have changed the default so that the retry time for these errors is now
1752 based a combination of the sender and recipient addresses. This change
1753 can be overridden by setting address_retry_include_sender=false in the
1754 smtp transport.

2022PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2023 "Deny" causes Exim to reject the incoming connection with a 554 error.
2024 Unfortunately, if there is a major crisis, such as a disk failure,
2025 tcp-wrappers gives "deny", whereas what one would like would be some
2026 kind of temporary error. A kludge has been added to help with this.
2027 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2028 554 error is used if errno is still zero or contains ENOENT (which occurs
2029 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2030 451 error is used.

2066PH/01 The code for finding all the local interface addresses on a FreeBSD
2067 system running IPv6 was broken. This may well have applied to all BSD
2068 systems, as well as to others that have similar system calls. The broken
2069 code found IPv4 interfaces correctly, but gave incorrect values for the
2070 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2071 that it would not match correctly against @[] and not recognize the IPv6
2072 addresses as local.

2115 autoreply, Exim could try to deliver to a non-existent relative file

2138 (a) Failures to set uid/gid, the current directory, or a process leader
2139 in a subprocess such as that created by queryprogram now generate
2140 suitable debugging ouput when -d is set.

2150 additional section of a DNS packet that returns MX or SRV records.
2151 Instead, it always explicitly searches for A/AAAA records. This avoids
2152 major problems that occur when a DNS server includes only records of one
2153 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2154 fixed another bug: if SRV records were looked up and the corresponding
2155 address records were *not* found in the additional section, the port
2156 values from the SRV records were lost.

2158PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2166PH/19 When calculating a retry time, Exim used to measure the "time since
2167 failure" by looking at the "first failed" field in the retry record. Now
2168 it does not use this if it is later than than the arrival time of the
2169 message. Instead it uses the arrival time. This makes for better
2170 behaviour in cases where some deliveries succeed, thus re-setting the
2171 "first failed" field. An example is a quota failure for a huge message
2172 when small messages continue to be delivered. Without this change, the
2173 "time since failure" will always be short, possible causing more frequent
2174 delivery attempts for the huge message than are intended.

PH
2271PH/42 The content-scanning code uses fopen() to create files in which to put
2272 message data. Previously it was not paying any attention to the mode of
2273 the files. Exim runs with umask(0) because the rest of the code creates
2274 files with open(), and sets the required mode explicitly. Thus, these
2275 files were ending up world-writeable. This was not a big issue, because,
2276 being within the spool directory, they were not world-accessible. I have
2277 created a function called modefopen, which takes an additional mode
2278 argument. It sets umask(777), creates the file, chmods it to the required
2279 mode, then resets the umask. All the relevant calls to fopen() in the

2317
2318 (i) Exim was not creating retry information for temporary errors given

2320 was used in LMTP mode. This meant that they could be retried too
2321 frequently, and not timed out correctly.
2322
2323 (ii) Exim was setting the flag that allows error details to be returned
2324 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2325 recipients that were returned after the DATA command.
2326
2327PH/53 This is related to PH/52, but is more general: for any failing address,
2328 when detailed error information was permitted to be returned to the

2401PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2402 function verify_get_ident() calls ip_connect() to connect a socket, but
2403 if the "connect()" function timed out, ip_connect() used to close the
2404 socket. However, verify_get_ident() also closes the socket later, and in
2405 between Exim writes to the log, which may get opened at this point. When
2406 the socket was closed in ip_connect(), the log could get the same file
2407 descriptor number as the socket. This naturally causes chaos. The fix is
2408 not to close the socket in ip_connect(); the socket should be closed by
2409 the function that creates it. There was only one place in the code where
2410 this was missing, in the iplookup router, which I don't think anybody now
2411 uses, but I've fixed it anyway.

2434
2435 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2436 string.
2437
2438 (3) Reset the variables that are obtained from the first argument of
2439 ${prvscheck and used in the second argument before leaving the code,
2440 because their memory is reclaimed, so using them afterwards may do
2441 silly things.
2442
2443 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2444 one (it's much easier than Tom thought :-).
2445
2446 (5) Because of (4), we can now allow for the use of $prvscheck_result

2462 may be more than one such address. If so, they are comma-separated, like

2467PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2468 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2469 not being looked up in the rDNS to get a host name, Exim was showing the
2470 IP address twice in Received: lines, even though the IP addresses were
2471 identical. For example:
2472
2473 Received: from [1.2.3.4] (helo=[1.2.3.4])
2474
2475 However, if the real host name was known, it was omitting the HELO data
2476 if it matched the actual IP address. This has been tidied up so that it
2477 doesn't show the same IP address twice.

2508 in the messages that it generates (bounce messages and others, such as
2509 warnings). In the case of bounce messages for non-SMTP mesages, there was
2510 also a typo: it was using "Auto_submitted" (underscore instead of
2511 hyphen). Since every message generated by Exim is necessarily in response
2512 to another message, thes have all been changed to:
2513
2514 Auto-Submitted: auto-replied
2515
2516 in accordance with these statements in the RFC:
2517
2518 The auto-replied keyword:

2566PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2568 the IP address, check_host() was doing a simple string comparison with
2569 addresses acquired from the DNS when checking that the found name did
2570 have the original IP as one of its addresses. Since any found IPv6
2571 addresses are likely to be in abbreviated form, the comparison could
2572 fail. Luckily, there already exists a function for doing the comparison
2573 by converting both addresses to binary, so now that is used instead of
2574 the text comparison.

2872 with the definition in sysexits.h (which is #included earlier).
2873 Fortunately, Exim does not actually use EX_OK. The code used to try to
2874 preserve the sysexits.h value, by assumimg that macro definitions were
2875 scanned for macro replacements. I have been disabused of this notion,

2881 This seems wrong - if the receiver was accepting one byte at a time it
2882 would take for ever. The timeout is now adjusted when this happens. It
2883 doesn't have to be particularly precise.

2960 suddenly stopped working when I started to use syslog. The patch checks

3092PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3093 that changes the way the GnuTLS parameters are stored in the cache file.
3094 The new format can be generated externally. For backward compatibility,
3095 if the data in the cache doesn't make sense, Exim assumes it has read an
3096 old-format file, and it generates new data and writes a new file. This
3097 means that you can't go back to an older release without removing the
3098 file.
3099
3100PH/03 A redirect router that has both "unseen" and "one_time" set does not
3101 work if there are any delivery delays because "one_time" forces the
3102 parent to be marked "delivered", so its unseen clone is never tried
3103 again. For this reason, Exim now forbids the simultaneous setting of
3104 these two options.
3105
3106PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3107 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3108 entry if you want to know the details. The fix, however, neglected to
3109 consider the case when local delivery batching is involved. The test for
3110 "previously delivered" was not happening when checking to see if an
3111 address could be batched with a previous (undelivered) one; under
3112 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3113 address.

PH
3114
3115PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3118PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3119 header_syntax) but Exim was just ignoring anything given after a slash.
3120 In particular, this caused confusion with an attempt to use "verify =
3121 reverse_host_lookup/defer_ok". An error is now given when options are
3122 supplied for verify items that do not have them. (Maybe reverse_host_
3123 lookup should have a defer_ok option, but that's a different point.)
3124
3125PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3159 and controls are allowed in which ACLs. There were a couple of minor
3160 errors. Some of the entries in the conditions table (which is a table of
3161 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3162 negation of where the condition IS allowed.

3175PH/19 When an Exim process that is running as root has to create an Exim log
3176 file, it does so in a subprocess that runs as exim:exim so as to get the
3177 ownership right at creation (otherwise, other Exim processes might see
3178 the file with the wrong ownership). There was no test for failure of this
3179 fork() call, which would lead to the process getting stuck as it waited
3180 for a non-existent subprocess. Forks do occasionally fail when resources
3181 run out. I reviewed all the other calls to fork(); they all seem to check
3182 for failure.

3184PH/20 When checking for unexpected SMTP input at connect time (before writing
3185 the banner), Exim was not dealing correctly with a non-positive return
3186 from the read() function. If the client had disconnected by this time,
3187 the result was a log entry for a synchronization error with an empty
3188 string after "input=" when read() returned zero. If read() returned -1
3189 (an event I could not check), uninitialized data bytes were printed.
3190 There were reports of junk text (parts of files, etc) appearing after

3201PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3202 hadn't been configured. The fix is from Juergen Kreileder, who
3203 understands it better than I do:
3204
3205 "Here's what I see happening with three configured cyrus_sasl
3206 authenticators configured (plain, login, cram-md5):
3207
3208 On startup auth_cyrus_sasl_init() gets called for each of these.
3209 This means three calls to sasl_listmech() without a specified mech_list.
3210 => SASL tests which mechs of all available mechs actually work
3211 => three warnings about OTP not working
3212 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3213
3214 With the patch, sasl_listmech() also gets called three times. But now
3215 SASL's mech_list option is set to the server_mech specified in the the
3216 authenticator. Or in other words, the answer from sasl_listmech()
3217 gets limited to just the mech you're testing for (which is different
3218 for each call.)
3219 => the return list contains just 'plain' or 'login', 'cram-md5' or
3220 nothing depending on the value of ob->server_mech.
3221
3222 I've just tested the patch: Authentication still works fine,
3223 unavailable mechs specified in the exim configuration are still
3224 caught, and the auth.log warnings about OTP are gone."

PH
3288PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3289 the grounds that routing the same address twice would always produce the
3290 same answer. This might have been true once, but it is certainly no
3291 longer true now. Routing a child address may depend on the previous
3292 routing that produced that child. Some complicated redirection strategies
3293 went wrong when messages had multiple recipients, and made Exim's
3294 behaviour dependent on the order in which the addresses were given.
3295
3296 I have moved the duplicate checking until after the routing is complete.
3297 Exim scans the addresses that are assigned to local and remote
3298 transports, and removes any duplicates. This means that more work will be
3299 done, as duplicates will always all be routed, but duplicates are
3300 presumably rare, so I don't expect this is of any significance.
3301
3302 For deliveries to pipes, files, and autoreplies, the duplicate checking
3303 still happens during the routing process, since they are not going to be
3304 routed further.

3310 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3311 blindly assumes that writes won't block so it may never time out."

3348 successful delivery. Such timeouts include transport filter timeouts. For
3349 consistency with the overall process timeout, these timeouts are now
3350 treated as errors, giving rise to delivery failures by default. However,
3351 there is now a new Boolean option for the pipe transport called
3352 timeout_defer, which, if set TRUE, converts the failures into defers for
3353 both kinds of timeout. A transport filter timeout is now identified in

3363A note about Exim versions 4.44 and 4.50
3364----------------------------------------
3365
3366Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3367changes of various kinds. As a consequence, a big documentation update was
3368needed. This delayed the release for rather longer than seemed good, especially
3369in the light of a couple of (minor) security issues. Therefore, the changes
3370that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3371release. So 4.44 and 4.50 are in effect two different branches that both start
3372from 4.43.
3373
3374I have left the 4.50 change log unchanged; it contains all the changes since
33754.43. The change log for 4.44 is below; many of its items are identical to
3376those for 4.50. This seems to be the most sensible way to preserve the
3377historical information.
