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.

206TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
207
208 When a queue runner is handling a message, Exim first routes the
209 recipient addresses, during which it prunes them based on the retry
210 hints database. After that it attempts to deliver the message to
211 any remaining recipients. It then updates the hints database using
212 the retry rules.
213
214 So if a recipient address works intermittently, it can get repeatedly
215 deferred at routing time. The retry hints record remains fresh so the
216 address never reaches the final cutoff time.
217
218 This is a fairly common occurrence when a user is bumping up against
219 their storage quota. Exim had some logic in its local delivery code
220 to deal with this. However it did not apply to per-recipient defers
221 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
222
1ddeb334
TF
223 This change adds a proper retry rule check during routing so that the
224 final cutoff time is checked against the message's age. We only do
225 this check if there is an address retry record and there is not a
226 domain retry record; this implies that previous attempts to handle
227 the address had the retry_use_local_parts option turned on. We use
228 this as an approximation for the destination being like a local
229 delivery, as in LMTP.
67bd1ab3
TF
230
231 I suspect this new check makes the old local delivery cutoff check
232 redundant, but I have not verified this so I left the code in place.

235
236 Test 0254 submits a message to Exim with the header
237
238 Resent-From: f
239
240 When I ran the test suite under the user fanf2, Exim expanded
241 the header to contain my full name, whereas it should have added
242 a Resent-Sender: header. It erroneously treats any prefix of the
243 username as equal to the username.
244
245 This change corrects that bug.

266JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
267 Server implementation by Todd Lyons, client by JH.
268 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
269 config variable "prdr_enable" controls whether the server
270 advertises the facility. If the client requests PRDR a new
271 acl_data_smtp_prdr ACL is called once for each recipient, after
272 the body content is received and before the acl_smtp_data ACL.
273 The client is controlled by bolth of: a hosts_try_prdr option
274 on the smtp transport, and the server advertisement.
275 Default client logging of deliveries and rejections involving
276 PRDR are flagged with the string "PRDR".

286 This is now consistent with GnuTLS, and is now documented: the

289 an empty string is now equivalent.

554TF/03 Make the exiwhat support code safe for signals. Previously Exim might
555 lock up or crash if it happened to be inside a call to libc when it
556 got a SIGUSR1 from exiwhat.
557
558 The SIGUSR1 handler appends the current process status to the process
559 log which is later printed by exiwhat. It used to use the general
560 purpose logging code to do this, but several functions it calls are
561 not safe for signals.
562
563 The new output code in the SIGUSR1 handler is specific to the process
564 log, and simple enough that it's easy to inspect for signal safety.
565 Removing some special cases also simplifies the general logging code.
566 Removing the spurious timestamps from the process log simplifies
567 exiwhat.
568
c99ce5c9
TF
569TF/04 Improved ratelimit ACL condition.
570
571 The /noupdate option has been deprecated in favour of /readonly which
572 has clearer semantics. The /leaky, /strict, and /readonly update modes
573 are mutually exclusive. The update mode is no longer included in the
574 database key; it just determines when the database is updated. (This
575 means that when you upgrde Exim will forget old rate measurements.)
576
577 Exim now checks that the per_* options are used with an update mode that
578 makes sense for the current ACL. For example, when Exim is processing a
579 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
580 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
581 must specify per_mail/readonly. If you omit the update mode it defaults to
582 /leaky where that makes sense (as before) or /readonly where required.
583
584 The /noupdate option is now undocumented but still supported for
585 backwards compatibility. It is equivalent to /readonly except that in
586 ACLs where /readonly is required you may specify /leaky/noupdate or
587 /strict/noupdate which are treated the same as /readonly.
588
589 A useful new feature is the /count= option. This is a generalization
590 of the per_byte option, so that you can measure the throughput of other
591 aggregate values. For example, the per_byte option is now equivalent
592 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
593
594 The per_rcpt option has been generalized using the /count= mechanism
595 (though it's more complicated than the per_byte equivalence). When it is
596 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
597 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
598 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
599 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
600 Note that using per_rcpt with a non-readonly update mode in more than
601 one ACL will cause the recipients to be double-counted. (The per_mail
602 and per_byte options don't have this problem.)
603
604 The handling of very low rates has changed slightly. If the computed rate
605 is less than the event's count (usually one) then this event is the first
606 after a long gap. In this case the rate is set to the same as this event's
607 count, so that the first message of a spam run is counted properly.
608
609 The major new feature is a mechanism for counting the rate of unique
610 events. The new per_addr option counts the number of different
611 recipients that someone has sent messages to in the last time period. It
612 behaves like per_rcpt if all the recipient addresses are different, but
613 duplicate recipient addresses do not increase the measured rate. Like
614 the /count= option this is a general mechanism, so the per_addr option
615 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
616 example, measure the rate that a client uses different sender addresses
617 with the options per_mail/unique=$sender_address. There are further
618 details in the main documentation.

829 If dropping privileges for untrusted macros, we disabled normal logging
830 on the basis that it would fail; for the Exim run-time user, this is not
831 the case, and it resulted in successful deliveries going unlogged.

1194 dots are used instead of colons so that keys in lsearch files need not
1195 contain colons. This was done some time before quoting was made available
1196 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1197 (notated using the quote facility) so as to distinguish them from IPv4
1198 keys. This meant that lookups for IP addresses in host lists did not work
1199 for iplsearch lookups.
1200
1201 This has been fixed by arranging for IPv6 addresses to be expressed with
1202 colons if the lookup type is iplsearch. This is not incompatible, because
1203 previously such lookups could never work.
1204
1205 The situation is now rather anomolous, since one *can* have colons in
1206 ordinary lsearch keys. However, making the change in all cases is
1207 incompatible and would probably break a number of configurations.

1212MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

1214 a rogue spamd server to cause a buffer overflow. While nobody in their
1215 right mind would setup Exim to query an untrusted spamd server, an
1216 attacker that gains access to a server running spamd could potentially
1217 exploit this vulnerability to run arbitrary code as the Exim user.

1413 some time before the response is written. In this time, more input might
1414 arrive, invalidly. So now there are extra checks after an ACL has run for
1415 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1416 pipelining has not been advertised.

1490 the response to the final '.' that terminates a message, but only in the

1492 (unfortunately, this is allowed). However, in many cases there won't be
1493 any further data because there won't be any more messages to send. A call
1494 to select() can be used: if it shows that the input is "ready", there is
1495 either input waiting, or the socket has been closed. An attempt to read
1496 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1497 would have sent an OK response which the client would never have see.

1509 fixed by 4.65/MH/01 (is this a record?) are fixed:
1510
1511 (i) An empty string was always treated as zero by the numeric comparison
1512 operators. This behaviour has been restored.
1513
1514 (ii) It is documented that the numeric comparison operators always treat
1515 their arguments as decimal numbers. This was broken in that numbers
1516 starting with 0 were being interpreted as octal.
1517
1518 While fixing these problems I realized that there was another issue that
1519 hadn't been noticed. Values of message_size_limit (both the global option
1520 and the transport option) were treated as octal if they started with 0.
1521 The documentation was vague. These values are now always treated as
1522 decimal, and I will make that clear in the documentation.

PH
1566PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1567 callout verification, Exim cached a "reject" for the entire domain. This
1568 is correct for most verifications, but it is not correct for a recipient
1569 verification with use_sender or use_postmaster set, because in that case
1570 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1571 case of MAIL FROM:<> rejection from other early rejections (e.g.
1572 rejection of HELO). When verifying a recipient using a non-null MAIL
1573 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1574 Whatever the result of the callout, the value of the domain cache is
1575 left unchanged (for any other kind of callout, getting as far as trying
1576 RCPT means that the domain itself is ok).

1610PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1611 hostname. This is wrong, because it relates to the incoming message (and
1612 probably the interface on which it is arriving) and not to the outgoing
1613 callout (which could be using a different interface). This has been
1614 changed to use the value of the helo_data option from the smtp transport
1615 instead - this is what is used when a message is actually being sent. If
1616 there is no remote transport (possible with a router that sets up host
1617 addresses), $smtp_active_hostname is used.

14aa5a05 1619PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1620 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1621 (a) The code assumed that strncpy() returns a negative number on buffer
1622 overflow, which isn't the case. Replaced with Exim's string_format()
1623 function.
1624 (b) There were several signed/unsigned issues. I just did the minimum
1625 hacking in of casts. There is scope for a larger refactoring.
1626 (c) The code used strcasecmp() which is not a standard C function.
1627 Replaced with Exim's strcmpic() function.
1628 (d) The code set only $1; it now sets $auth1 as well.
1629 (e) A simple test gave the error "authentication client didn't specify
1630 service in request". It would seem that Dovecot has changed its
1631 interface. Fortunately there's a specification; I followed it and
1632 changed what the client sends and it appears to be working now.

1637PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1638 address A is aliased to B and C, where B exists and C does not. Without
1639 -v the output is "A verified" because verification stops after a
1640 successful redirection if more than one address is generated. However,
1641 with -v the child addresses are also verified. Exim was outputting "A
1642 failed to verify" and then showing the successful verification for C,
1643 with its parentage. It now outputs "B failed to verify", showing B's
1644 parentage before showing the successful verification of C.

1649
322050c2
PH
1650PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1651 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1652 they consult the DNS. I had assumed they would set it the way they
1653 wanted; and indeed my experiments on Linux seem to show that in some
1654 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1655 To be on the safe side, however, I have now made the interface to
1656 host_find_byname() similar to host_find_bydns(), with an argument
1657 containing the DNS resolver options. The host_find_byname() function now
1658 sets these options at its start, just as host_find_bydns() does. The smtp
1659 transport options dns_qualify_single and dns_search_parents are passed to
1660 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1661 of host_find_byname() use the default settings of RES_DEFNAMES
1662 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1664PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1665 spool_read_header() do less string testing, by means of a preliminary
1666 switch on the second character of optional "-foo" lines. (This is
1667 overdue, caused by the large number of possibilities that now exist.
1668 Originally there were few.) While I was there, I also converted the
1669 str(n)cmp tests so they don't re-test the leading "-" and the first
1670 character, in the hope this might squeeze out yet more improvement.
1671

PH
1672PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1673 flag allowing group syntax was set by the header_syntax check but not
1674 turned off, possible causing trouble later; (2) The flag was not being
1675 set at all for the header_verify test, causing "group"-style headers to
1676 be rejected. I have now set it in this case, and also caused header_
1677 verify to ignore an empty address taken from a group. While doing this, I
1678 came across some other cases where the code for allowing group syntax
1679 while scanning a header line wasn't quite right (mostly, not resetting
1680 the flag correctly in the right place). These bugs could have caused
1681 trouble for malformed header lines. I hope it is now all correct.
1682
602e59e5
PH
1683PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1684 with the "reply" argument non-NULL. The code, however (which originally
1685 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1686 but it didn't always do it. This confused somebody who was copying the
1687 code for some other use. I have removed all the tests.

PH
1689PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1690 feature that was used to support insecure browsers during the U.S. crypto
1691 embargo. It requires special client support, and Exim is probably the
1692 only MTA that supported it -- and would never use it because real RSA is
1693 always available. This code has been removed, because it had the bad
1694 effect of slowing Exim down by computing (never used) parameters for the
1695 RSA_EXPORT functionality.

7befa435
PH
1697PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1698 authenticator to fail if there's a tab character in the incoming data
1699 (there should never be unless someone is messing about, as it's supposed
1700 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1701 if the connection is using TLS or if the remote IP is the same as the
1702 local IP, and the "valid-client-cert option" if a client certificate has
1703 been verified.

1734
1735PH/30 Exim was sometimes attempting to deliver messages that had suffered
1736 address errors (4xx response to RCPT) over the same connection as other
1737 messages routed to the same hosts. Such deliveries are always "forced",
1738 so retry times are not inspected. This resulted in far too many retries
1739 for the affected addresses. The effect occurred only when there were more
1740 hosts than the hosts_max_try setting in the smtp transport when it had
1741 the 4xx errors. Those hosts that it had tried were not added to the list
1742 of hosts for which the message was waiting, so if all were tried, there
1743 was no problem. Two fixes have been applied:
1744
1745 (i) If there are any address or message errors in an SMTP delivery, none
1746 of the hosts (tried or untried) are now added to the list of hosts
1747 for which the message is waiting, so the message should not be a
1748 candidate for sending over the same connection that was used for a
1749 successful delivery of some other message. This seems entirely
1750 reasonable: after all the message is NOT "waiting for some host".
1751 This is so "obvious" that I'm not sure why it wasn't done
1752 previously. Hope I haven't missed anything, but it can't do any
1753 harm, as the worst effect is to miss an optimization.
1754
1755 (ii) If, despite (i), such a delivery is accidentally attempted, the
1756 routing retry time is respected, so at least it doesn't keep
1757 hammering the server.

1772PH/35 The error "getsockname() failed: connection reset by peer" was being
1773 written to the panic log as well as the main log, but it isn't really
1774 panic-worthy as it just means the connection died rather early on. I have
1775 removed the panic log writing for the ECONNRESET error when getsockname()
1776 fails.
1777
48c7f9e2
PH
1778PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1779 runs only) independently of the message's sender address. This meant
1780 that, if the 4xx error was in fact related to the sender, a different
1781 message to the same recipient with a different sender could confuse
1782 things. In particualar, this can happen when sending to a greylisting
1783 server, but other circumstances could also provoke similar problems.
1784 I have changed the default so that the retry time for these errors is now
1785 based a combination of the sender and recipient addresses. This change
1786 can be overridden by setting address_retry_include_sender=false in the
1787 smtp transport.

2055PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2057 Unfortunately, if there is a major crisis, such as a disk failure,
2058 tcp-wrappers gives "deny", whereas what one would like would be some
2059 kind of temporary error. A kludge has been added to help with this.
2060 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2061 554 error is used if errno is still zero or contains ENOENT (which occurs
2062 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2063 451 error is used.

2099PH/01 The code for finding all the local interface addresses on a FreeBSD
2100 system running IPv6 was broken. This may well have applied to all BSD
2101 systems, as well as to others that have similar system calls. The broken
2102 code found IPv4 interfaces correctly, but gave incorrect values for the
2103 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2104 that it would not match correctly against @[] and not recognize the IPv6
2105 addresses as local.

2148 autoreply, Exim could try to deliver to a non-existent relative file

2171 (a) Failures to set uid/gid, the current directory, or a process leader
2172 in a subprocess such as that created by queryprogram now generate
2173 suitable debugging ouput when -d is set.

2177 the subprocess without attempting to change uid/gid.

2183 additional section of a DNS packet that returns MX or SRV records.
2184 Instead, it always explicitly searches for A/AAAA records. This avoids
2185 major problems that occur when a DNS server includes only records of one
2186 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2187 fixed another bug: if SRV records were looked up and the corresponding
2188 address records were *not* found in the additional section, the port
2189 values from the SRV records were lost.

2191PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2199PH/19 When calculating a retry time, Exim used to measure the "time since
2200 failure" by looking at the "first failed" field in the retry record. Now
2201 it does not use this if it is later than than the arrival time of the
2202 message. Instead it uses the arrival time. This makes for better
2203 behaviour in cases where some deliveries succeed, thus re-setting the
2204 "first failed" field. An example is a quota failure for a huge message
2205 when small messages continue to be delivered. Without this change, the
2206 "time since failure" will always be short, possible causing more frequent
2207 delivery attempts for the huge message than are intended.

2304PH/42 The content-scanning code uses fopen() to create files in which to put

2307 files with open(), and sets the required mode explicitly. Thus, these
2308 files were ending up world-writeable. This was not a big issue, because,
2309 being within the spool directory, they were not world-accessible. I have
2310 created a function called modefopen, which takes an additional mode
2311 argument. It sets umask(777), creates the file, chmods it to the required
2312 mode, then resets the umask. All the relevant calls to fopen() in the

2349 used in LMTP mode:
2350
2351 (i) Exim was not creating retry information for temporary errors given
2352 for individual recipients after the DATA command when the smtp transport
2353 was used in LMTP mode. This meant that they could be retried too
2354 frequently, and not timed out correctly.
2355
2356 (ii) Exim was setting the flag that allows error details to be returned
2357 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2358 recipients that were returned after the DATA command.
2359
2360PH/53 This is related to PH/52, but is more general: for any failing address,
2361 when detailed error information was permitted to be returned to the
2362 sender, but the error was temporary, then after the final timeout, only
2363 "retry timeout exceeded" was returned. Now it returns the full error as
2364 well as "retry timeout exceeded".

2420PH/68 The bounce_return_message and bounce_return_body options were not being
2421 honoured for bounces generated during the reception of non-SMTP messages.
2422 In particular, this applied to messages rejected by the ACL. This bug has
2423 been fixed. However, if bounce_return_message is true and bounce_return_
2424 body is false, the headers that are returned for a non-SMTP message
2425 include only those that have been read before the error was detected.

PH
2434PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2435 function verify_get_ident() calls ip_connect() to connect a socket, but
2436 if the "connect()" function timed out, ip_connect() used to close the
2437 socket. However, verify_get_ident() also closes the socket later, and in
2438 between Exim writes to the log, which may get opened at this point. When
2439 the socket was closed in ip_connect(), the log could get the same file
2440 descriptor number as the socket. This naturally causes chaos. The fix is
2441 not to close the socket in ip_connect(); the socket should be closed by
2442 the function that creates it. There was only one place in the code where
2443 this was missing, in the iplookup router, which I don't think anybody now
2444 uses, but I've fixed it anyway.

2463PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2464
2465 (1) Generate an error if the third argument for the ${prvs expansion is
2466 not a single digit.
2467
2468 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2469 string.
2470
2471 (3) Reset the variables that are obtained from the first argument of
2472 ${prvscheck and used in the second argument before leaving the code,
2473 because their memory is reclaimed, so using them afterwards may do
2474 silly things.
2475
2476 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2477 one (it's much easier than Tom thought :-).
2478
2479 (5) Because of (4), we can now allow for the use of $prvscheck_result
2480 inside the third argument.

2490 quoted in the delivery log line, like this:
2491
2492 => >A.N.Other <ano@some.domain> <original@ddress> ...
2493
2494 This has been changed so that it extracts the operative address. There
2495 may be more than one such address. If so, they are comma-separated, like
2496 this:
2497
2498 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2500PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2501 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2502 not being looked up in the rDNS to get a host name, Exim was showing the
2503 IP address twice in Received: lines, even though the IP addresses were
2504 identical. For example:
2505
2506 Received: from [1.2.3.4] (helo=[1.2.3.4])
2507
2508 However, if the real host name was known, it was omitting the HELO data
2509 if it matched the actual IP address. This has been tidied up so that it
2510 doesn't show the same IP address twice.

2512PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2536PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2537 Electronic Mail") by including:
2538
2539 Auto-submitted: auto-generated
2540
2541 in the messages that it generates (bounce messages and others, such as
2542 warnings). In the case of bounce messages for non-SMTP mesages, there was
2543 also a typo: it was using "Auto_submitted" (underscore instead of
2544 hyphen). Since every message generated by Exim is necessarily in response
2545 to another message, thes have all been changed to:
2546
2547 Auto-Submitted: auto-replied
2548
2549 in accordance with these statements in the RFC:
2550
2551 The auto-replied keyword:
2552
2553 - SHOULD be used on messages sent in direct response to another
2554 message by an automatic process,
2555
2556 - MUST NOT be used on manually-generated messages,
2557
2558 - MAY be used on Delivery Status Notifications (DSNs) and Message
2559 Disposition Notifications (MDNs),
2560
2561 - MUST NOT be used on messages generated by automatic or periodic
2562 processes, except for messages which are automatic responses to
2563 other messages.

PH
2599PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2600 canonical form (as documented). However, after a host name lookup from
2601 the IP address, check_host() was doing a simple string comparison with
2602 addresses acquired from the DNS when checking that the found name did
2603 have the original IP as one of its addresses. Since any found IPv6
2604 addresses are likely to be in abbreviated form, the comparison could
2605 fail. Luckily, there already exists a function for doing the comparison
2606 by converting both addresses to binary, so now that is used instead of
2607 the text comparison.

PH
2609PH/20 There was another similar case to PH/19, when a complete host name was

2905 with the definition in sysexits.h (which is #included earlier).
2906 Fortunately, Exim does not actually use EX_OK. The code used to try to
2907 preserve the sysexits.h value, by assumimg that macro definitions were
2908 scanned for macro replacements. I have been disabused of this notion,

2914 This seems wrong - if the receiver was accepting one byte at a time it
2915 would take for ever. The timeout is now adjusted when this happens. It
2916 doesn't have to be particularly precise.

2991 the logs files are, rather than using the compiled in default. In our
2992 case the guess is not the same as the compiled default, so the script
2993 suddenly stopped working when I started to use syslog. The patch checks
2994 to see if log_file_path is "". If so, it attempts to read it from exim

2996 falls back to the previous guessing code."

3125PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3126 that changes the way the GnuTLS parameters are stored in the cache file.
3127 The new format can be generated externally. For backward compatibility,
3128 if the data in the cache doesn't make sense, Exim assumes it has read an
3129 old-format file, and it generates new data and writes a new file. This
3130 means that you can't go back to an older release without removing the
3131 file.
3132
3133PH/03 A redirect router that has both "unseen" and "one_time" set does not
3134 work if there are any delivery delays because "one_time" forces the
3135 parent to be marked "delivered", so its unseen clone is never tried
3136 again. For this reason, Exim now forbids the simultaneous setting of
3137 these two options.

3139PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3140 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3141 entry if you want to know the details. The fix, however, neglected to
3142 consider the case when local delivery batching is involved. The test for
3143 "previously delivered" was not happening when checking to see if an
3144 address could be batched with a previous (undelivered) one; under
3145 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3146 address.

3208PH/19 When an Exim process that is running as root has to create an Exim log
3209 file, it does so in a subprocess that runs as exim:exim so as to get the
3210 ownership right at creation (otherwise, other Exim processes might see
3211 the file with the wrong ownership). There was no test for failure of this
3212 fork() call, which would lead to the process getting stuck as it waited
3213 for a non-existent subprocess. Forks do occasionally fail when resources
3214 run out. I reviewed all the other calls to fork(); they all seem to check
3215 for failure.

3217PH/20 When checking for unexpected SMTP input at connect time (before writing

3219 from the read() function. If the client had disconnected by this time,
3220 the result was a log entry for a synchronization error with an empty
3221 string after "input=" when read() returned zero. If read() returned -1
3222 (an event I could not check), uninitialized data bytes were printed.

3233
c5ddb310
PH
3234PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3235 hadn't been configured. The fix is from Juergen Kreileder, who
3236 understands it better than I do:
3237
3238 "Here's what I see happening with three configured cyrus_sasl
3239 authenticators configured (plain, login, cram-md5):
3240
3241 On startup auth_cyrus_sasl_init() gets called for each of these.
3242 This means three calls to sasl_listmech() without a specified mech_list.
3243 => SASL tests which mechs of all available mechs actually work
3244 => three warnings about OTP not working
3245 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3246
3247 With the patch, sasl_listmech() also gets called three times. But now
3248 SASL's mech_list option is set to the server_mech specified in the the
3249 authenticator. Or in other words, the answer from sasl_listmech()
3250 gets limited to just the mech you're testing for (which is different
3251 for each call.)
3252 => the return list contains just 'plain' or 'login', 'cram-md5' or
3253 nothing depending on the value of ob->server_mech.
3254
3255 I've just tested the patch: Authentication still works fine,
3256 unavailable mechs specified in the exim configuration are still
3257 caught, and the auth.log warnings about OTP are gone."

3293 . Second host offers TLS and a TLS session is established;

PH
3321PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3322 the grounds that routing the same address twice would always produce the
3323 same answer. This might have been true once, but it is certainly no
3324 longer true now. Routing a child address may depend on the previous
3325 routing that produced that child. Some complicated redirection strategies
3326 went wrong when messages had multiple recipients, and made Exim's
3327 behaviour dependent on the order in which the addresses were given.
3328
3329 I have moved the duplicate checking until after the routing is complete.
3330 Exim scans the addresses that are assigned to local and remote
3331 transports, and removes any duplicates. This means that more work will be
3332 done, as duplicates will always all be routed, but duplicates are
3333 presumably rare, so I don't expect this is of any significance.
3334
3335 For deliveries to pipes, files, and autoreplies, the duplicate checking
3336 still happens during the routing process, since they are not going to be
3337 routed further.

3343 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3344 blindly assumes that writes won't block so it may never time out."
