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.

45 results permerror and temperror. Previous values are deprecated but
46 still accepted. In a future release, err_perm and err_temp will be
47 completely removed, which will be a backward incompatibility if the

188TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
189
190 When a queue runner is handling a message, Exim first routes the
191 recipient addresses, during which it prunes them based on the retry
192 hints database. After that it attempts to deliver the message to
193 any remaining recipients. It then updates the hints database using
194 the retry rules.
195
196 So if a recipient address works intermittently, it can get repeatedly
197 deferred at routing time. The retry hints record remains fresh so the
198 address never reaches the final cutoff time.
199
200 This is a fairly common occurrence when a user is bumping up against
201 their storage quota. Exim had some logic in its local delivery code
202 to deal with this. However it did not apply to per-recipient defers
203 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
204
1ddeb334
TF
205 This change adds a proper retry rule check during routing so that the
206 final cutoff time is checked against the message's age. We only do
207 this check if there is an address retry record and there is not a
208 domain retry record; this implies that previous attempts to handle
209 the address had the retry_use_local_parts option turned on. We use
210 this as an approximation for the destination being like a local
211 delivery, as in LMTP.
67bd1ab3
TF
212
213 I suspect this new check makes the old local delivery cutoff check
214 redundant, but I have not verified this so I left the code in place.

216TF/02 Correct gecos expansion when From: is a prefix of the username.
217
218 Test 0254 submits a message to Exim with the header
219
220 Resent-From: f
221
222 When I ran the test suite under the user fanf2, Exim expanded
223 the header to contain my full name, whereas it should have added
224 a Resent-Sender: header. It erroneously treats any prefix of the
225 username as equal to the username.
226
227 This change corrects that bug.

248JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
249 Server implementation by Todd Lyons, client by JH.
250 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
251 config variable "prdr_enable" controls whether the server
252 advertises the facility. If the client requests PRDR a new
253 acl_data_smtp_prdr ACL is called once for each recipient, after
254 the body content is received and before the acl_smtp_data ACL.
255 The client is controlled by bolth of: a hosts_try_prdr option
256 on the smtp transport, and the server advertisement.
257 Default client logging of deliveries and rejections involving
258 PRDR are flagged with the string "PRDR".

267PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
268 This is now consistent with GnuTLS, and is now documented: the
269 previous undocumented portable approach to treating the option as
270 unset was to force an expansion failure. That still works, and
271 an empty string is now equivalent.

536TF/03 Make the exiwhat support code safe for signals. Previously Exim might
537 lock up or crash if it happened to be inside a call to libc when it
538 got a SIGUSR1 from exiwhat.
539
540 The SIGUSR1 handler appends the current process status to the process
541 log which is later printed by exiwhat. It used to use the general
542 purpose logging code to do this, but several functions it calls are
543 not safe for signals.
544
545 The new output code in the SIGUSR1 handler is specific to the process
546 log, and simple enough that it's easy to inspect for signal safety.
547 Removing some special cases also simplifies the general logging code.
548 Removing the spurious timestamps from the process log simplifies
549 exiwhat.
550
c99ce5c9
TF
551TF/04 Improved ratelimit ACL condition.
552
553 The /noupdate option has been deprecated in favour of /readonly which
554 has clearer semantics. The /leaky, /strict, and /readonly update modes
555 are mutually exclusive. The update mode is no longer included in the
556 database key; it just determines when the database is updated. (This
557 means that when you upgrde Exim will forget old rate measurements.)
558
559 Exim now checks that the per_* options are used with an update mode that
560 makes sense for the current ACL. For example, when Exim is processing a
561 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
562 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
563 must specify per_mail/readonly. If you omit the update mode it defaults to
564 /leaky where that makes sense (as before) or /readonly where required.
565
566 The /noupdate option is now undocumented but still supported for
567 backwards compatibility. It is equivalent to /readonly except that in
568 ACLs where /readonly is required you may specify /leaky/noupdate or
569 /strict/noupdate which are treated the same as /readonly.
570
571 A useful new feature is the /count= option. This is a generalization
572 of the per_byte option, so that you can measure the throughput of other
573 aggregate values. For example, the per_byte option is now equivalent
574 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
575
576 The per_rcpt option has been generalized using the /count= mechanism
577 (though it's more complicated than the per_byte equivalence). When it is
578 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
579 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
580 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
581 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
582 Note that using per_rcpt with a non-readonly update mode in more than
583 one ACL will cause the recipients to be double-counted. (The per_mail
584 and per_byte options don't have this problem.)
585
586 The handling of very low rates has changed slightly. If the computed rate
587 is less than the event's count (usually one) then this event is the first
588 after a long gap. In this case the rate is set to the same as this event's
589 count, so that the first message of a spam run is counted properly.
590
591 The major new feature is a mechanism for counting the rate of unique
592 events. The new per_addr option counts the number of different
593 recipients that someone has sent messages to in the last time period. It
594 behaves like per_rcpt if all the recipient addresses are different, but
595 duplicate recipient addresses do not increase the measured rate. Like
596 the /count= option this is a general mechanism, so the per_addr option
597 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
598 example, measure the rate that a client uses different sender addresses
599 with the options per_mail/unique=$sender_address. There are further
600 details in the main documentation.

1151 were called 'true' and it seems that C99 defines that as a reserved

1172PH/01 Another patch from the Sieve maintainer.
1173
6a3bceb1
PH
1174PH/02 When an IPv6 address is converted to a string for single-key lookup
1175 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1176 dots are used instead of colons so that keys in lsearch files need not
1177 contain colons. This was done some time before quoting was made available
1178 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1179 (notated using the quote facility) so as to distinguish them from IPv4
1180 keys. This meant that lookups for IP addresses in host lists did not work
1181 for iplsearch lookups.
1182
1183 This has been fixed by arranging for IPv6 addresses to be expressed with
1184 colons if the lookup type is iplsearch. This is not incompatible, because
1185 previously such lookups could never work.
1186
1187 The situation is now rather anomolous, since one *can* have colons in
1188 ordinary lsearch keys. However, making the change in all cases is
1189 incompatible and would probably break a number of configurations.

MH
1194MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1195 conversion specification without a maximum field width, thereby enabling
1196 a rogue spamd server to cause a buffer overflow. While nobody in their

1392PH/29 SMTP synchronization checks are implemented when a command is read -
1393 there is a check that no more input is waiting when there shouldn't be

1395 some time before the response is written. In this time, more input might
1396 arrive, invalidly. So now there are extra checks after an ACL has run for
1397 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1398 pipelining has not been advertised.

PH
1472 the response to the final '.' that terminates a message, but only in the
1473 case where the client has not sent further data following the '.'
1474 (unfortunately, this is allowed). However, in many cases there won't be
1475 any further data because there won't be any more messages to send. A call
1476 to select() can be used: if it shows that the input is "ready", there is
1477 either input waiting, or the socket has been closed. An attempt to read
1478 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1479 would have sent an OK response which the client would never have see.

1490PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1491 fixed by 4.65/MH/01 (is this a record?) are fixed:
1492
1493 (i) An empty string was always treated as zero by the numeric comparison
1494 operators. This behaviour has been restored.
1495
1496 (ii) It is documented that the numeric comparison operators always treat
1497 their arguments as decimal numbers. This was broken in that numbers
1498 starting with 0 were being interpreted as octal.
1499
1500 While fixing these problems I realized that there was another issue that
1501 hadn't been noticed. Values of message_size_limit (both the global option
1502 and the transport option) were treated as octal if they started with 0.
1503 The documentation was vague. These values are now always treated as
1504 decimal, and I will make that clear in the documentation.

PH
1548PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1549 callout verification, Exim cached a "reject" for the entire domain. This
1550 is correct for most verifications, but it is not correct for a recipient
1551 verification with use_sender or use_postmaster set, because in that case
1552 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1553 case of MAIL FROM:<> rejection from other early rejections (e.g.
1554 rejection of HELO). When verifying a recipient using a non-null MAIL
1555 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1556 Whatever the result of the callout, the value of the domain cache is
1557 left unchanged (for any other kind of callout, getting as far as trying
1558 RCPT means that the domain itself is ok).

1592PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1593 hostname. This is wrong, because it relates to the incoming message (and
1594 probably the interface on which it is arriving) and not to the outgoing
1595 callout (which could be using a different interface). This has been
1596 changed to use the value of the helo_data option from the smtp transport
1597 instead - this is what is used when a message is actually being sent. If
1598 there is no remote transport (possible with a router that sets up host
1599 addresses), $smtp_active_hostname is used.

14aa5a05 1601PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1602 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1603 (a) The code assumed that strncpy() returns a negative number on buffer
1604 overflow, which isn't the case. Replaced with Exim's string_format()
1605 function.
1606 (b) There were several signed/unsigned issues. I just did the minimum
1607 hacking in of casts. There is scope for a larger refactoring.
1608 (c) The code used strcasecmp() which is not a standard C function.
1609 Replaced with Exim's strcmpic() function.
1610 (d) The code set only $1; it now sets $auth1 as well.
1611 (e) A simple test gave the error "authentication client didn't specify
1612 service in request". It would seem that Dovecot has changed its
1613 interface. Fortunately there's a specification; I followed it and
1614 changed what the client sends and it appears to be working now.

PH
1619PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1620 address A is aliased to B and C, where B exists and C does not. Without
1621 -v the output is "A verified" because verification stops after a
1622 successful redirection if more than one address is generated. However,
1623 with -v the child addresses are also verified. Exim was outputting "A
1624 failed to verify" and then showing the successful verification for C,
1625 with its parentage. It now outputs "B failed to verify", showing B's
1626 parentage before showing the successful verification of C.

PH
1628PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1629 look up a TXT record in a specific list after matching in a combined
1630 list.
1631
322050c2
PH
1632PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1633 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1634 they consult the DNS. I had assumed they would set it the way they
1635 wanted; and indeed my experiments on Linux seem to show that in some
1636 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1637 To be on the safe side, however, I have now made the interface to
1638 host_find_byname() similar to host_find_bydns(), with an argument
1639 containing the DNS resolver options. The host_find_byname() function now
1640 sets these options at its start, just as host_find_bydns() does. The smtp
1641 transport options dns_qualify_single and dns_search_parents are passed to
1642 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1643 of host_find_byname() use the default settings of RES_DEFNAMES
1644 (qualify_single) but not RES_DNSRCH (search_parents).
1645

PH
1646PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1647 spool_read_header() do less string testing, by means of a preliminary
1648 switch on the second character of optional "-foo" lines. (This is
1649 overdue, caused by the large number of possibilities that now exist.
1650 Originally there were few.) While I was there, I also converted the
1651 str(n)cmp tests so they don't re-test the leading "-" and the first
1652 character, in the hope this might squeeze out yet more improvement.
1653
1eccaa59
PH
1654PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1655 flag allowing group syntax was set by the header_syntax check but not
1656 turned off, possible causing trouble later; (2) The flag was not being
1657 set at all for the header_verify test, causing "group"-style headers to
1658 be rejected. I have now set it in this case, and also caused header_
1659 verify to ignore an empty address taken from a group. While doing this, I
1660 came across some other cases where the code for allowing group syntax
1661 while scanning a header line wasn't quite right (mostly, not resetting
1662 the flag correctly in the right place). These bugs could have caused
1663 trouble for malformed header lines. I hope it is now all correct.
1664
602e59e5
PH
1665PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1666 with the "reply" argument non-NULL. The code, however (which originally
1667 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1668 but it didn't always do it. This confused somebody who was copying the
1669 code for some other use. I have removed all the tests.
1670
411ef850
PH
1671PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1672 feature that was used to support insecure browsers during the U.S. crypto
1673 embargo. It requires special client support, and Exim is probably the
1674 only MTA that supported it -- and would never use it because real RSA is
1675 always available. This code has been removed, because it had the bad
1676 effect of slowing Exim down by computing (never used) parameters for the
1677 RSA_EXPORT functionality.
1678
7befa435
PH
1679PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1680 authenticator to fail if there's a tab character in the incoming data
1681 (there should never be unless someone is messing about, as it's supposed
1682 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1683 if the connection is using TLS or if the remote IP is the same as the
1684 local IP, and the "valid-client-cert option" if a client certificate has
1685 been verified.
1686
48da4259 1687PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

1688 authenticators. This can be used for authorization after authentication
1689 succeeds. (In the case of plaintext, it servers for both authentication
1690 and authorization.)

PH
1716
1717PH/30 Exim was sometimes attempting to deliver messages that had suffered
1718 address errors (4xx response to RCPT) over the same connection as other
1719 messages routed to the same hosts. Such deliveries are always "forced",
1720 so retry times are not inspected. This resulted in far too many retries
1721 for the affected addresses. The effect occurred only when there were more
1722 hosts than the hosts_max_try setting in the smtp transport when it had
1723 the 4xx errors. Those hosts that it had tried were not added to the list
1724 of hosts for which the message was waiting, so if all were tried, there
1725 was no problem. Two fixes have been applied:
1726
1727 (i) If there are any address or message errors in an SMTP delivery, none
1728 of the hosts (tried or untried) are now added to the list of hosts
1729 for which the message is waiting, so the message should not be a
1730 candidate for sending over the same connection that was used for a
1731 successful delivery of some other message. This seems entirely
1732 reasonable: after all the message is NOT "waiting for some host".
1733 This is so "obvious" that I'm not sure why it wasn't done
1734 previously. Hope I haven't missed anything, but it can't do any
1735 harm, as the worst effect is to miss an optimization.
1736
1737 (ii) If, despite (i), such a delivery is accidentally attempted, the
1738 routing retry time is respected, so at least it doesn't keep
1739 hammering the server.

1750PH/34 The spec says: "With one important exception, whenever a domain list is

520de300
PH
1754PH/35 The error "getsockname() failed: connection reset by peer" was being
1755 written to the panic log as well as the main log, but it isn't really
1756 panic-worthy as it just means the connection died rather early on. I have
1757 removed the panic log writing for the ECONNRESET error when getsockname()
1758 fails.
1759
48c7f9e2
PH
1760PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1761 runs only) independently of the message's sender address. This meant
1762 that, if the 4xx error was in fact related to the sender, a different
1763 message to the same recipient with a different sender could confuse
1764 things. In particualar, this can happen when sending to a greylisting
1765 server, but other circumstances could also provoke similar problems.
1766 I have changed the default so that the retry time for these errors is now
1767 based a combination of the sender and recipient addresses. This change
1768 can be overridden by setting address_retry_include_sender=false in the
1769 smtp transport.

PH
1771PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

1774 same for both kinds of LMTP.

2037PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2039 Unfortunately, if there is a major crisis, such as a disk failure,
2040 tcp-wrappers gives "deny", whereas what one would like would be some
2041 kind of temporary error. A kludge has been added to help with this.
2042 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2043 554 error is used if errno is still zero or contains ENOENT (which occurs
2044 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2045 451 error is used.

2081PH/01 The code for finding all the local interface addresses on a FreeBSD

2084 code found IPv4 interfaces correctly, but gave incorrect values for the
2085 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2086 that it would not match correctly against @[] and not recognize the IPv6
2087 addresses as local.

2130 autoreply, Exim could try to deliver to a non-existent relative file

2166 Instead, it always explicitly searches for A/AAAA records. This avoids
2167 major problems that occur when a DNS server includes only records of one
2168 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2169 fixed another bug: if SRV records were looked up and the corresponding
2170 address records were *not* found in the additional section, the port
2171 values from the SRV records were lost.

2181PH/19 When calculating a retry time, Exim used to measure the "time since
2182 failure" by looking at the "first failed" field in the retry record. Now
2183 it does not use this if it is later than than the arrival time of the
2184 message. Instead it uses the arrival time. This makes for better
2185 behaviour in cases where some deliveries succeed, thus re-setting the
2186 "first failed" field. An example is a quota failure for a huge message
2187 when small messages continue to be delivered. Without this change, the
2188 "time since failure" will always be short, possible causing more frequent
2189 delivery attempts for the huge message than are intended.

PH
2286PH/42 The content-scanning code uses fopen() to create files in which to put
2287 message data. Previously it was not paying any attention to the mode of
2288 the files. Exim runs with umask(0) because the rest of the code creates
2289 files with open(), and sets the required mode explicitly. Thus, these
2290 files were ending up world-writeable. This was not a big issue, because,
2291 being within the spool directory, they were not world-accessible. I have
2292 created a function called modefopen, which takes an additional mode
2293 argument. It sets umask(777), creates the file, chmods it to the required
2294 mode, then resets the umask. All the relevant calls to fopen() in the

2335 was used in LMTP mode. This meant that they could be retried too
2336 frequently, and not timed out correctly.
2337
2338 (ii) Exim was setting the flag that allows error details to be returned
2339 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2340 recipients that were returned after the DATA command.
2341
2342PH/53 This is related to PH/52, but is more general: for any failing address,
2343 when detailed error information was permitted to be returned to the

2402PH/68 The bounce_return_message and bounce_return_body options were not being
2403 honoured for bounces generated during the reception of non-SMTP messages.
2404 In particular, this applied to messages rejected by the ACL. This bug has
2405 been fixed. However, if bounce_return_message is true and bounce_return_
2406 body is false, the headers that are returned for a non-SMTP message
2407 include only those that have been read before the error was detected.

2410PH/69 The HTML version of the specification is now built in a directory called

PH
2416PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2417 function verify_get_ident() calls ip_connect() to connect a socket, but
2418 if the "connect()" function timed out, ip_connect() used to close the
2419 socket. However, verify_get_ident() also closes the socket later, and in
2420 between Exim writes to the log, which may get opened at this point. When
2421 the socket was closed in ip_connect(), the log could get the same file
2422 descriptor number as the socket. This naturally causes chaos. The fix is
2423 not to close the socket in ip_connect(); the socket should be closed by
2424 the function that creates it. There was only one place in the code where
2425 this was missing, in the iplookup router, which I don't think anybody now
2426 uses, but I've fixed it anyway.

2441 (2) Add control=submission to the relay_from_hosts and authenticated

2445PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2446
2447 (1) Generate an error if the third argument for the ${prvs expansion is
2448 not a single digit.
2449
2450 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2451 string.
2452
2453 (3) Reset the variables that are obtained from the first argument of
2454 ${prvscheck and used in the second argument before leaving the code,
2455 because their memory is reclaimed, so using them afterwards may do
2456 silly things.
2457
2458 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2459 one (it's much easier than Tom thought :-).
2460
2461 (5) Because of (4), we can now allow for the use of $prvscheck_result
2462 inside the third argument.

2471PH/05 When a filter generated an autoreply, the entire To: header line was
2472 quoted in the delivery log line, like this:
2473
2474 => >A.N.Other <ano@some.domain> <original@ddress> ...
2475
2476 This has been changed so that it extracts the operative address. There
2477 may be more than one such address. If so, they are comma-separated, like
2478 this:
2479
2480 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2482PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2483 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2484 not being looked up in the rDNS to get a host name, Exim was showing the
2485 IP address twice in Received: lines, even though the IP addresses were
2486 identical. For example:
2487
2488 Received: from [1.2.3.4] (helo=[1.2.3.4])
2489
2490 However, if the real host name was known, it was omitting the HELO data
2491 if it matched the actual IP address. This has been tidied up so that it
2492 doesn't show the same IP address twice.

PH
2494PH/07 When both +timestamp and +memory debugging was on, the value given by
2495 $tod_xxx expansions could be wrong, because the tod_stamp() function was

PH
2518PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2519 Electronic Mail") by including:
2520
2521 Auto-submitted: auto-generated
2522
2523 in the messages that it generates (bounce messages and others, such as
2524 warnings). In the case of bounce messages for non-SMTP mesages, there was
2525 also a typo: it was using "Auto_submitted" (underscore instead of
2526 hyphen). Since every message generated by Exim is necessarily in response
2527 to another message, thes have all been changed to:
2528
2529 Auto-Submitted: auto-replied
2530
2531 in accordance with these statements in the RFC:
2532
2533 The auto-replied keyword:
2534
2535 - SHOULD be used on messages sent in direct response to another
2536 message by an automatic process,
2537
2538 - MUST NOT be used on manually-generated messages,
2539
2540 - MAY be used on Delivery Status Notifications (DSNs) and Message
2541 Disposition Notifications (MDNs),
2542
2543 - MUST NOT be used on messages generated by automatic or periodic
2544 processes, except for messages which are automatic responses to
2545 other messages.

2567 extension "envelope-auth". The code is finished and in agreement with

2569 nobody wrote the draft yet. This extension is currently #undef'ed, thus
2570 not changing the active code.

PH
2581PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2582 canonical form (as documented). However, after a host name lookup from
2583 the IP address, check_host() was doing a simple string comparison with
2584 addresses acquired from the DNS when checking that the found name did
2585 have the original IP as one of its addresses. Since any found IPv6
2586 addresses are likely to be in abbreviated form, the comparison could
2587 fail. Luckily, there already exists a function for doing the comparison
2588 by converting both addresses to binary, so now that is used instead of
2589 the text comparison.
2590
96776534
PH
2591PH/20 There was another similar case to PH/19, when a complete host name was

2768 From: header, and the sender address was obtained from -f or from an SMTP
2769 MAIL command, and the trusted user did not use -F to supply a sender
2770 name, $originator_name was incorrectly used when constructing a From:
2771 header. Furthermore, $originator_name was used for submission mode

2887 with the definition in sysexits.h (which is #included earlier).
2888 Fortunately, Exim does not actually use EX_OK. The code used to try to
2889 preserve the sysexits.h value, by assumimg that macro definitions were
2890 scanned for macro replacements. I have been disabused of this notion,

2897 would take for ever. The timeout is now adjusted when this happens. It
2898 doesn't have to be particularly precise.

3107PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3108 that changes the way the GnuTLS parameters are stored in the cache file.
3109 The new format can be generated externally. For backward compatibility,
3110 if the data in the cache doesn't make sense, Exim assumes it has read an
3111 old-format file, and it generates new data and writes a new file. This
3112 means that you can't go back to an older release without removing the
3113 file.
3114
3115PH/03 A redirect router that has both "unseen" and "one_time" set does not
3116 work if there are any delivery delays because "one_time" forces the
3117 parent to be marked "delivered", so its unseen clone is never tried
3118 again. For this reason, Exim now forbids the simultaneous setting of
3119 these two options.
3120
3121PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3122 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3123 entry if you want to know the details. The fix, however, neglected to
3124 consider the case when local delivery batching is involved. The test for
3125 "previously delivered" was not happening when checking to see if an
3126 address could be batched with a previous (undelivered) one; under
3127 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3128 address.

3133PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3134 header_syntax) but Exim was just ignoring anything given after a slash.
3135 In particular, this caused confusion with an attempt to use "verify =
3136 reverse_host_lookup/defer_ok". An error is now given when options are
3137 supplied for verify items that do not have them. (Maybe reverse_host_
3138 lookup should have a defer_ok option, but that's a different point.)

3140PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3190PH/19 When an Exim process that is running as root has to create an Exim log
3191 file, it does so in a subprocess that runs as exim:exim so as to get the
3192 ownership right at creation (otherwise, other Exim processes might see
3193 the file with the wrong ownership). There was no test for failure of this
3194 fork() call, which would lead to the process getting stuck as it waited
3195 for a non-existent subprocess. Forks do occasionally fail when resources
3196 run out. I reviewed all the other calls to fork(); they all seem to check
3197 for failure.

3199PH/20 When checking for unexpected SMTP input at connect time (before writing
3200 the banner), Exim was not dealing correctly with a non-positive return
3201 from the read() function. If the client had disconnected by this time,
3202 the result was a log entry for a synchronization error with an empty
3203 string after "input=" when read() returned zero. If read() returned -1
3204 (an event I could not check), uninitialized data bytes were printed.
3205 There were reports of junk text (parts of files, etc) appearing after

PH
3216PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3217 hadn't been configured. The fix is from Juergen Kreileder, who
3218 understands it better than I do:
3219
3220 "Here's what I see happening with three configured cyrus_sasl
3221 authenticators configured (plain, login, cram-md5):
3222
3223 On startup auth_cyrus_sasl_init() gets called for each of these.
3224 This means three calls to sasl_listmech() without a specified mech_list.
3225 => SASL tests which mechs of all available mechs actually work
3226 => three warnings about OTP not working
3227 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3228
3229 With the patch, sasl_listmech() also gets called three times. But now
3230 SASL's mech_list option is set to the server_mech specified in the the
3231 authenticator. Or in other words, the answer from sasl_listmech()
3232 gets limited to just the mech you're testing for (which is different
3233 for each call.)
3234 => the return list contains just 'plain' or 'login', 'cram-md5' or
3235 nothing depending on the value of ob->server_mech.
3236
3237 I've just tested the patch: Authentication still works fine,
3238 unavailable mechs specified in the exim configuration are still
3239 caught, and the auth.log warnings about OTP are gone."

3275 . Second host offers TLS and a TLS session is established;

PH
3303PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3304 the grounds that routing the same address twice would always produce the
3305 same answer. This might have been true once, but it is certainly no
3306 longer true now. Routing a child address may depend on the previous
3307 routing that produced that child. Some complicated redirection strategies
3308 went wrong when messages had multiple recipients, and made Exim's
3309 behaviour dependent on the order in which the addresses were given.
3310
3311 I have moved the duplicate checking until after the routing is complete.
3312 Exim scans the addresses that are assigned to local and remote
3313 transports, and removes any duplicates. This means that more work will be
3314 done, as duplicates will always all be routed, but duplicates are
3315 presumably rare, so I don't expect this is of any significance.
3316
3317 For deliveries to pipes, files, and autoreplies, the duplicate checking
3318 still happens during the routing process, since they are not going to be
3319 routed further.

3324 connection it has accepted, or it never writes response data. The exiscan
3325 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3326 blindly assumes that writes won't block so it may never time out."

3344 (a) An SMTP error message from a remote host;

3347 (d) A message specified in a FAIL return from the queryprogram router;
3348 (e) A message specified by the cannot_route_message router option.

3350 In these cases only, Exim does include the error details in bounce and
3351 warning messages. There are also a few cases where bland messages such
3352 as "unrouteable address" or "local delivery error" are given.

3360PH/45 In a pipe transport, although a timeout while waiting for the pipe
3361 process to complete was treated as a delivery failure, a timeout while
3362 writing the message to the pipe was logged, but erroneously treated as a
3363 successful delivery. Such timeouts include transport filter timeouts. For
3364 consistency with the overall process timeout, these timeouts are now
3365 treated as errors, giving rise to delivery failures by default. However,
3366 there is now a new Boolean option for the pipe transport called
3367 timeout_defer, which, if set TRUE, converts the failures into defers for
3368 both kinds of timeout. A transport filter timeout is now identified in
3369 the log output.
