6-----------------

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.

211TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
212
213 When a queue runner is handling a message, Exim first routes the
214 recipient addresses, during which it prunes them based on the retry
215 hints database. After that it attempts to deliver the message to
216 any remaining recipients. It then updates the hints database using
217 the retry rules.
218
219 So if a recipient address works intermittently, it can get repeatedly
220 deferred at routing time. The retry hints record remains fresh so the
221 address never reaches the final cutoff time.
222
223 This is a fairly common occurrence when a user is bumping up against
224 their storage quota. Exim had some logic in its local delivery code
225 to deal with this. However it did not apply to per-recipient defers
226 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
227
1ddeb334
TF
228 This change adds a proper retry rule check during routing so that the
229 final cutoff time is checked against the message's age. We only do
230 this check if there is an address retry record and there is not a
231 domain retry record; this implies that previous attempts to handle
232 the address had the retry_use_local_parts option turned on. We use
233 this as an approximation for the destination being like a local
234 delivery, as in LMTP.
67bd1ab3
TF
235
236 I suspect this new check makes the old local delivery cutoff check
237 redundant, but I have not verified this so I left the code in place.

240
241 Test 0254 submits a message to Exim with the header
242
243 Resent-From: f
244
245 When I ran the test suite under the user fanf2, Exim expanded
246 the header to contain my full name, whereas it should have added
247 a Resent-Sender: header. It erroneously treats any prefix of the
248 username as equal to the username.
249
250 This change corrects that bug.

271JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
272 Server implementation by Todd Lyons, client by JH.
273 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
274 config variable "prdr_enable" controls whether the server
275 advertises the facility. If the client requests PRDR a new
276 acl_data_smtp_prdr ACL is called once for each recipient, after
277 the body content is received and before the acl_smtp_data ACL.
278 The client is controlled by bolth of: a hosts_try_prdr option
279 on the smtp transport, and the server advertisement.
280 Default client logging of deliveries and rejections involving
281 PRDR are flagged with the string "PRDR".

559TF/03 Make the exiwhat support code safe for signals. Previously Exim might
560 lock up or crash if it happened to be inside a call to libc when it
561 got a SIGUSR1 from exiwhat.
562
563 The SIGUSR1 handler appends the current process status to the process
564 log which is later printed by exiwhat. It used to use the general
565 purpose logging code to do this, but several functions it calls are
566 not safe for signals.
567
568 The new output code in the SIGUSR1 handler is specific to the process
569 log, and simple enough that it's easy to inspect for signal safety.
570 Removing some special cases also simplifies the general logging code.
571 Removing the spurious timestamps from the process log simplifies
572 exiwhat.
573
c99ce5c9
TF
574TF/04 Improved ratelimit ACL condition.
575
576 The /noupdate option has been deprecated in favour of /readonly which
577 has clearer semantics. The /leaky, /strict, and /readonly update modes
578 are mutually exclusive. The update mode is no longer included in the
579 database key; it just determines when the database is updated. (This
580 means that when you upgrde Exim will forget old rate measurements.)
581
582 Exim now checks that the per_* options are used with an update mode that
583 makes sense for the current ACL. For example, when Exim is processing a
584 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
585 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
586 must specify per_mail/readonly. If you omit the update mode it defaults to
587 /leaky where that makes sense (as before) or /readonly where required.
588
589 The /noupdate option is now undocumented but still supported for
590 backwards compatibility. It is equivalent to /readonly except that in
591 ACLs where /readonly is required you may specify /leaky/noupdate or
592 /strict/noupdate which are treated the same as /readonly.
593
594 A useful new feature is the /count= option. This is a generalization
595 of the per_byte option, so that you can measure the throughput of other
596 aggregate values. For example, the per_byte option is now equivalent
597 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
598
599 The per_rcpt option has been generalized using the /count= mechanism
600 (though it's more complicated than the per_byte equivalence). When it is
601 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
602 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
603 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
604 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
605 Note that using per_rcpt with a non-readonly update mode in more than
606 one ACL will cause the recipients to be double-counted. (The per_mail
607 and per_byte options don't have this problem.)
608
609 The handling of very low rates has changed slightly. If the computed rate
610 is less than the event's count (usually one) then this event is the first
611 after a long gap. In this case the rate is set to the same as this event's
612 count, so that the first message of a spam run is counted properly.
613
614 The major new feature is a mechanism for counting the rate of unique
615 events. The new per_addr option counts the number of different
616 recipients that someone has sent messages to in the last time period. It
617 behaves like per_rcpt if all the recipient addresses are different, but
618 duplicate recipient addresses do not increase the measured rate. Like
619 the /count= option this is a general mechanism, so the per_addr option
620 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
621 example, measure the rate that a client uses different sender addresses
622 with the options per_mail/unique=$sender_address. There are further
623 details in the main documentation.

PH
1197PH/02 When an IPv6 address is converted to a string for single-key lookup
1198 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1199 dots are used instead of colons so that keys in lsearch files need not
1200 contain colons. This was done some time before quoting was made available
1201 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1202 (notated using the quote facility) so as to distinguish them from IPv4
1203 keys. This meant that lookups for IP addresses in host lists did not work
1204 for iplsearch lookups.
1205
1206 This has been fixed by arranging for IPv6 addresses to be expressed with
1207 colons if the lookup type is iplsearch. This is not incompatible, because
1208 previously such lookups could never work.
1209
1210 The situation is now rather anomolous, since one *can* have colons in
1211 ordinary lsearch keys. However, making the change in all cases is
1212 incompatible and would probably break a number of configurations.

1217MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1218 conversion specification without a maximum field width, thereby enabling
1219 a rogue spamd server to cause a buffer overflow. While nobody in their
1220 right mind would setup Exim to query an untrusted spamd server, an
1221 attacker that gains access to a server running spamd could potentially
1222 exploit this vulnerability to run arbitrary code as the Exim user.

1227MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for

1230 Exim lacked permissions to read, a lookup for a key matching that

1415PH/29 SMTP synchronization checks are implemented when a command is read -
1416 there is a check that no more input is waiting when there shouldn't be

1418 some time before the response is written. In this time, more input might
1419 arrive, invalidly. So now there are extra checks after an ACL has run for
1420 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1421 pipelining has not been advertised.

1436 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1437 was a macro that became an assignment, so it seemed to work. This has

1495 the response to the final '.' that terminates a message, but only in the
1496 case where the client has not sent further data following the '.'
1497 (unfortunately, this is allowed). However, in many cases there won't be
1498 any further data because there won't be any more messages to send. A call
1499 to select() can be used: if it shows that the input is "ready", there is
1500 either input waiting, or the socket has been closed. An attempt to read
1501 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1502 would have sent an OK response which the client would never have see.

1513PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1514 fixed by 4.65/MH/01 (is this a record?) are fixed:
1515
1516 (i) An empty string was always treated as zero by the numeric comparison
1517 operators. This behaviour has been restored.
1518
1519 (ii) It is documented that the numeric comparison operators always treat
1520 their arguments as decimal numbers. This was broken in that numbers
1521 starting with 0 were being interpreted as octal.
1522
1523 While fixing these problems I realized that there was another issue that
1524 hadn't been noticed. Values of message_size_limit (both the global option
1525 and the transport option) were treated as octal if they started with 0.
1526 The documentation was vague. These values are now always treated as
1527 decimal, and I will make that clear in the documentation.

PH
1571PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1572 callout verification, Exim cached a "reject" for the entire domain. This
1573 is correct for most verifications, but it is not correct for a recipient
1574 verification with use_sender or use_postmaster set, because in that case
1575 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1576 case of MAIL FROM:<> rejection from other early rejections (e.g.
1577 rejection of HELO). When verifying a recipient using a non-null MAIL
1578 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1579 Whatever the result of the callout, the value of the domain cache is
1580 left unchanged (for any other kind of callout, getting as far as trying
1581 RCPT means that the domain itself is ok).

1615PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1616 hostname. This is wrong, because it relates to the incoming message (and
1617 probably the interface on which it is arriving) and not to the outgoing
1618 callout (which could be using a different interface). This has been
1619 changed to use the value of the helo_data option from the smtp transport
1620 instead - this is what is used when a message is actually being sent. If
1621 there is no remote transport (possible with a router that sets up host
1622 addresses), $smtp_active_hostname is used.

14aa5a05 1624PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1625 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1626 (a) The code assumed that strncpy() returns a negative number on buffer
1627 overflow, which isn't the case. Replaced with Exim's string_format()
1628 function.
1629 (b) There were several signed/unsigned issues. I just did the minimum
1630 hacking in of casts. There is scope for a larger refactoring.
1631 (c) The code used strcasecmp() which is not a standard C function.
1632 Replaced with Exim's strcmpic() function.
1633 (d) The code set only $1; it now sets $auth1 as well.
1634 (e) A simple test gave the error "authentication client didn't specify
1635 service in request". It would seem that Dovecot has changed its
1636 interface. Fortunately there's a specification; I followed it and
1637 changed what the client sends and it appears to be working now.

1642PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1643 address A is aliased to B and C, where B exists and C does not. Without
1644 -v the output is "A verified" because verification stops after a
1645 successful redirection if more than one address is generated. However,
1646 with -v the child addresses are also verified. Exim was outputting "A
1647 failed to verify" and then showing the successful verification for C,
1648 with its parentage. It now outputs "B failed to verify", showing B's
1649 parentage before showing the successful verification of C.

1654
322050c2
PH
1655PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1656 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1657 they consult the DNS. I had assumed they would set it the way they
1658 wanted; and indeed my experiments on Linux seem to show that in some
1659 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1660 To be on the safe side, however, I have now made the interface to
1661 host_find_byname() similar to host_find_bydns(), with an argument
1662 containing the DNS resolver options. The host_find_byname() function now
1663 sets these options at its start, just as host_find_bydns() does. The smtp
1664 transport options dns_qualify_single and dns_search_parents are passed to
1665 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1666 of host_find_byname() use the default settings of RES_DEFNAMES
1667 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1669PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1670 spool_read_header() do less string testing, by means of a preliminary
1671 switch on the second character of optional "-foo" lines. (This is
1672 overdue, caused by the large number of possibilities that now exist.
1673 Originally there were few.) While I was there, I also converted the
1674 str(n)cmp tests so they don't re-test the leading "-" and the first
1675 character, in the hope this might squeeze out yet more improvement.
1676

PH
1677PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1678 flag allowing group syntax was set by the header_syntax check but not
1679 turned off, possible causing trouble later; (2) The flag was not being
1680 set at all for the header_verify test, causing "group"-style headers to
1681 be rejected. I have now set it in this case, and also caused header_
1682 verify to ignore an empty address taken from a group. While doing this, I
1683 came across some other cases where the code for allowing group syntax
1684 while scanning a header line wasn't quite right (mostly, not resetting
1685 the flag correctly in the right place). These bugs could have caused
1686 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1688PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1689 with the "reply" argument non-NULL. The code, however (which originally
1690 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1691 but it didn't always do it. This confused somebody who was copying the
1692 code for some other use. I have removed all the tests.

411ef850
PH
1694PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1695 feature that was used to support insecure browsers during the U.S. crypto
1696 embargo. It requires special client support, and Exim is probably the
1697 only MTA that supported it -- and would never use it because real RSA is
1698 always available. This code has been removed, because it had the bad
1699 effect of slowing Exim down by computing (never used) parameters for the
1700 RSA_EXPORT functionality.

7befa435
PH
1702PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1703 authenticator to fail if there's a tab character in the incoming data
1704 (there should never be unless someone is messing about, as it's supposed
1705 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1706 if the connection is using TLS or if the remote IP is the same as the
1707 local IP, and the "valid-client-cert option" if a client certificate has
1708 been verified.

1739
1740PH/30 Exim was sometimes attempting to deliver messages that had suffered
1741 address errors (4xx response to RCPT) over the same connection as other
1742 messages routed to the same hosts. Such deliveries are always "forced",
1743 so retry times are not inspected. This resulted in far too many retries
1744 for the affected addresses. The effect occurred only when there were more
1745 hosts than the hosts_max_try setting in the smtp transport when it had
1746 the 4xx errors. Those hosts that it had tried were not added to the list
1747 of hosts for which the message was waiting, so if all were tried, there
1748 was no problem. Two fixes have been applied:
1749
1750 (i) If there are any address or message errors in an SMTP delivery, none
1751 of the hosts (tried or untried) are now added to the list of hosts
1752 for which the message is waiting, so the message should not be a
1753 candidate for sending over the same connection that was used for a
1754 successful delivery of some other message. This seems entirely
1755 reasonable: after all the message is NOT "waiting for some host".
1756 This is so "obvious" that I'm not sure why it wasn't done
1757 previously. Hope I haven't missed anything, but it can't do any
1758 harm, as the worst effect is to miss an optimization.
1759
1760 (ii) If, despite (i), such a delivery is accidentally attempted, the
1761 routing retry time is respected, so at least it doesn't keep
1762 hammering the server.

1777PH/35 The error "getsockname() failed: connection reset by peer" was being
1778 written to the panic log as well as the main log, but it isn't really
1779 panic-worthy as it just means the connection died rather early on. I have
1780 removed the panic log writing for the ECONNRESET error when getsockname()
1781 fails.
1782
48c7f9e2
PH
1783PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1784 runs only) independently of the message's sender address. This meant
1785 that, if the 4xx error was in fact related to the sender, a different
1786 message to the same recipient with a different sender could confuse
1787 things. In particualar, this can happen when sending to a greylisting
1788 server, but other circumstances could also provoke similar problems.
1789 I have changed the default so that the retry time for these errors is now
1790 based a combination of the sender and recipient addresses. This change
1791 can be overridden by setting address_retry_include_sender=false in the
1792 smtp transport.

2060PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2062 Unfortunately, if there is a major crisis, such as a disk failure,
2063 tcp-wrappers gives "deny", whereas what one would like would be some
2064 kind of temporary error. A kludge has been added to help with this.
2065 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2066 554 error is used if errno is still zero or contains ENOENT (which occurs
2067 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2068 451 error is used.

2104PH/01 The code for finding all the local interface addresses on a FreeBSD
2105 system running IPv6 was broken. This may well have applied to all BSD
2106 systems, as well as to others that have similar system calls. The broken
2107 code found IPv4 interfaces correctly, but gave incorrect values for the
2108 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2109 that it would not match correctly against @[] and not recognize the IPv6
2110 addresses as local.

2153 autoreply, Exim could try to deliver to a non-existent relative file
2154 name, causing unrelated and misleading errors. What now happens is that

2175
2176 (a) Failures to set uid/gid, the current directory, or a process leader
2177 in a subprocess such as that created by queryprogram now generate
2178 suitable debugging ouput when -d is set.
2179

2182 the subprocess without attempting to change uid/gid.

2187PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2188 additional section of a DNS packet that returns MX or SRV records.
2189 Instead, it always explicitly searches for A/AAAA records. This avoids
2190 major problems that occur when a DNS server includes only records of one
2191 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2192 fixed another bug: if SRV records were looked up and the corresponding
2193 address records were *not* found in the additional section, the port
2194 values from the SRV records were lost.

2196PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
2204PH/19 When calculating a retry time, Exim used to measure the "time since
2205 failure" by looking at the "first failed" field in the retry record. Now
2206 it does not use this if it is later than than the arrival time of the
2207 message. Instead it uses the arrival time. This makes for better
2208 behaviour in cases where some deliveries succeed, thus re-setting the
2209 "first failed" field. An example is a quota failure for a huge message
2210 when small messages continue to be delivered. Without this change, the
2211 "time since failure" will always be short, possible causing more frequent
2212 delivery attempts for the huge message than are intended.

2309PH/42 The content-scanning code uses fopen() to create files in which to put

2312 files with open(), and sets the required mode explicitly. Thus, these
2313 files were ending up world-writeable. This was not a big issue, because,
2314 being within the spool directory, they were not world-accessible. I have
2315 created a function called modefopen, which takes an additional mode
2316 argument. It sets umask(777), creates the file, chmods it to the required
2317 mode, then resets the umask. All the relevant calls to fopen() in the

2353PH/52 Two bugs concerned with error handling when the smtp transport is
2354 used in LMTP mode:
2355
2356 (i) Exim was not creating retry information for temporary errors given
2357 for individual recipients after the DATA command when the smtp transport
2358 was used in LMTP mode. This meant that they could be retried too
2359 frequently, and not timed out correctly.
2360
2361 (ii) Exim was setting the flag that allows error details to be returned
2362 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2363 recipients that were returned after the DATA command.
2364
2365PH/53 This is related to PH/52, but is more general: for any failing address,
2366 when detailed error information was permitted to be returned to the
2367 sender, but the error was temporary, then after the final timeout, only
2368 "retry timeout exceeded" was returned. Now it returns the full error as
2369 well as "retry timeout exceeded".

2425PH/68 The bounce_return_message and bounce_return_body options were not being
2426 honoured for bounces generated during the reception of non-SMTP messages.
2427 In particular, this applied to messages rejected by the ACL. This bug has
2428 been fixed. However, if bounce_return_message is true and bounce_return_
2429 body is false, the headers that are returned for a non-SMTP message
2430 include only those that have been read before the error was detected.

PH
2439PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2440 function verify_get_ident() calls ip_connect() to connect a socket, but
2441 if the "connect()" function timed out, ip_connect() used to close the
2442 socket. However, verify_get_ident() also closes the socket later, and in
2443 between Exim writes to the log, which may get opened at this point. When
2444 the socket was closed in ip_connect(), the log could get the same file
2445 descriptor number as the socket. This naturally causes chaos. The fix is
2446 not to close the socket in ip_connect(); the socket should be closed by
2447 the function that creates it. There was only one place in the code where
2448 this was missing, in the iplookup router, which I don't think anybody now
2449 uses, but I've fixed it anyway.

2468PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2469
2470 (1) Generate an error if the third argument for the ${prvs expansion is
2471 not a single digit.
2472
2473 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2474 string.
2475
2476 (3) Reset the variables that are obtained from the first argument of
2477 ${prvscheck and used in the second argument before leaving the code,
2478 because their memory is reclaimed, so using them afterwards may do
2479 silly things.
2480
2481 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2482 one (it's much easier than Tom thought :-).
2483
2484 (5) Because of (4), we can now allow for the use of $prvscheck_result
2485 inside the third argument.

2495 quoted in the delivery log line, like this:
2496
2497 => >A.N.Other <ano@some.domain> <original@ddress> ...
2498
2499 This has been changed so that it extracts the operative address. There
2500 may be more than one such address. If so, they are comma-separated, like
2501 this:
2502
2503 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2505PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2506 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2507 not being looked up in the rDNS to get a host name, Exim was showing the
2508 IP address twice in Received: lines, even though the IP addresses were
2509 identical. For example:
2510
2511 Received: from [1.2.3.4] (helo=[1.2.3.4])
2512
2513 However, if the real host name was known, it was omitting the HELO data
2514 if it matched the actual IP address. This has been tidied up so that it
2515 doesn't show the same IP address twice.

2517PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2541PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2542 Electronic Mail") by including:
2543
2544 Auto-submitted: auto-generated
2545
2546 in the messages that it generates (bounce messages and others, such as
2547 warnings). In the case of bounce messages for non-SMTP mesages, there was
2548 also a typo: it was using "Auto_submitted" (underscore instead of
2549 hyphen). Since every message generated by Exim is necessarily in response
2550 to another message, thes have all been changed to:
2551
2552 Auto-Submitted: auto-replied
2553
2554 in accordance with these statements in the RFC:
2555
2556 The auto-replied keyword:
2557
2558 - SHOULD be used on messages sent in direct response to another
2559 message by an automatic process,
2560
2561 - MUST NOT be used on manually-generated messages,
2562
2563 - MAY be used on Delivery Status Notifications (DSNs) and Message
2564 Disposition Notifications (MDNs),
2565
2566 - MUST NOT be used on messages generated by automatic or periodic
2567 processes, except for messages which are automatic responses to
2568 other messages.

PH
2604PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2605 canonical form (as documented). However, after a host name lookup from
2606 the IP address, check_host() was doing a simple string comparison with
2607 addresses acquired from the DNS when checking that the found name did
2608 have the original IP as one of its addresses. Since any found IPv6
2609 addresses are likely to be in abbreviated form, the comparison could
2610 fail. Luckily, there already exists a function for doing the comparison
2611 by converting both addresses to binary, so now that is used instead of
2612 the text comparison.
2613
96776534
PH
2614PH/20 There was another similar case to PH/19, when a complete host name was

2910 with the definition in sysexits.h (which is #included earlier).
2911 Fortunately, Exim does not actually use EX_OK. The code used to try to
2912 preserve the sysexits.h value, by assumimg that macro definitions were
2913 scanned for macro replacements. I have been disabused of this notion,
2914 so now the code just undefines EX_OK before #including unistd.h.

2919 This seems wrong - if the receiver was accepting one byte at a time it
2920 would take for ever. The timeout is now adjusted when this happens. It
2921 doesn't have to be particularly precise.

2996 the logs files are, rather than using the compiled in default. In our
2997 case the guess is not the same as the compiled default, so the script
2998 suddenly stopped working when I started to use syslog. The patch checks
2999 to see if log_file_path is "". If so, it attempts to read it from exim
3000 with no configuration file to get the compiled in version, before it
3001 falls back to the previous guessing code."

3129
3130PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3131 that changes the way the GnuTLS parameters are stored in the cache file.
3132 The new format can be generated externally. For backward compatibility,
3133 if the data in the cache doesn't make sense, Exim assumes it has read an
3134 old-format file, and it generates new data and writes a new file. This
3135 means that you can't go back to an older release without removing the
3136 file.
3137
3138PH/03 A redirect router that has both "unseen" and "one_time" set does not
3139 work if there are any delivery delays because "one_time" forces the
3140 parent to be marked "delivered", so its unseen clone is never tried
3141 again. For this reason, Exim now forbids the simultaneous setting of
3142 these two options.
3143
3144PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3145 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3146 entry if you want to know the details. The fix, however, neglected to
3147 consider the case when local delivery batching is involved. The test for
3148 "previously delivered" was not happening when checking to see if an
3149 address could be batched with a previous (undelivered) one; under
3150 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3151 address.

PH
3152
3153PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3156PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3157 header_syntax) but Exim was just ignoring anything given after a slash.
3158 In particular, this caused confusion with an attempt to use "verify =
3159 reverse_host_lookup/defer_ok". An error is now given when options are
3160 supplied for verify items that do not have them. (Maybe reverse_host_
3161 lookup should have a defer_ok option, but that's a different point.)

3163PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3213PH/19 When an Exim process that is running as root has to create an Exim log
3214 file, it does so in a subprocess that runs as exim:exim so as to get the
3215 ownership right at creation (otherwise, other Exim processes might see
3216 the file with the wrong ownership). There was no test for failure of this
3217 fork() call, which would lead to the process getting stuck as it waited
3218 for a non-existent subprocess. Forks do occasionally fail when resources
3219 run out. I reviewed all the other calls to fork(); they all seem to check
3220 for failure.

3222PH/20 When checking for unexpected SMTP input at connect time (before writing

3224 from the read() function. If the client had disconnected by this time,
3225 the result was a log entry for a synchronization error with an empty
3226 string after "input=" when read() returned zero. If read() returned -1
3227 (an event I could not check), uninitialized data bytes were printed.

3238
c5ddb310
PH
3239PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3240 hadn't been configured. The fix is from Juergen Kreileder, who
3241 understands it better than I do:
3242
3243 "Here's what I see happening with three configured cyrus_sasl
3244 authenticators configured (plain, login, cram-md5):
3245
3246 On startup auth_cyrus_sasl_init() gets called for each of these.
3247 This means three calls to sasl_listmech() without a specified mech_list.
3248 => SASL tests which mechs of all available mechs actually work
3249 => three warnings about OTP not working
3250 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3251
3252 With the patch, sasl_listmech() also gets called three times. But now
3253 SASL's mech_list option is set to the server_mech specified in the the
3254 authenticator. Or in other words, the answer from sasl_listmech()
3255 gets limited to just the mech you're testing for (which is different
3256 for each call.)
3257 => the return list contains just 'plain' or 'login', 'cram-md5' or
3258 nothing depending on the value of ob->server_mech.
3259
3260 I've just tested the patch: Authentication still works fine,
3261 unavailable mechs specified in the exim configuration are still
3262 caught, and the auth.log warnings about OTP are gone."

3298 . Second host offers TLS and a TLS session is established;

PH
3326PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3327 the grounds that routing the same address twice would always produce the
3328 same answer. This might have been true once, but it is certainly no
3329 longer true now. Routing a child address may depend on the previous
3330 routing that produced that child. Some complicated redirection strategies
3331 went wrong when messages had multiple recipients, and made Exim's
3332 behaviour dependent on the order in which the addresses were given.
3333
3334 I have moved the duplicate checking until after the routing is complete.
3335 Exim scans the addresses that are assigned to local and remote
3336 transports, and removes any duplicates. This means that more work will be
3337 done, as duplicates will always all be routed, but duplicates are
3338 presumably rare, so I don't expect this is of any significance.
3339
3340 For deliveries to pipes, files, and autoreplies, the duplicate checking
3341 still happens during the routing process, since they are not going to be
3342 routed further.

3347 connection it has accepted, or it never writes response data. The exiscan
3348 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3349 blindly assumes that writes won't block so it may never time out."
