8TF/01 Correctly close the server side of TLS when forking for delivery.
9
10 When a message was received over SMTP with TLS, Exim failed to clear up
11 the incoming connection properly after forking off the child process to
12 deliver the message. In some situations the subsequent outgoing
13 delivery connection happened to have the same fd number as the incoming
14 connection previously had. Exim would try to use TLS and fail, logging
15 a "Bad file descriptor" error.

TF
191TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
192
193 When a queue runner is handling a message, Exim first routes the
194 recipient addresses, during which it prunes them based on the retry
195 hints database. After that it attempts to deliver the message to
196 any remaining recipients. It then updates the hints database using
197 the retry rules.
198
199 So if a recipient address works intermittently, it can get repeatedly
200 deferred at routing time. The retry hints record remains fresh so the
201 address never reaches the final cutoff time.
202
203 This is a fairly common occurrence when a user is bumping up against
204 their storage quota. Exim had some logic in its local delivery code
205 to deal with this. However it did not apply to per-recipient defers
206 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
207
1ddeb334
TF
208 This change adds a proper retry rule check during routing so that the
209 final cutoff time is checked against the message's age. We only do
210 this check if there is an address retry record and there is not a
211 domain retry record; this implies that previous attempts to handle
212 the address had the retry_use_local_parts option turned on. We use
213 this as an approximation for the destination being like a local
214 delivery, as in LMTP.
67bd1ab3
TF
215
216 I suspect this new check makes the old local delivery cutoff check
217 redundant, but I have not verified this so I left the code in place.

220
221 Test 0254 submits a message to Exim with the header
222
223 Resent-From: f
224
225 When I ran the test suite under the user fanf2, Exim expanded
226 the header to contain my full name, whereas it should have added
227 a Resent-Sender: header. It erroneously treats any prefix of the
228 username as equal to the username.
229
230 This change corrects that bug.

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

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

274 an empty string is now equivalent.

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

1154 were called 'true' and it seems that C99 defines that as a reserved

1156 not include C99-style headers which use bools without triggering

1175PH/01 Another patch from the Sieve maintainer.
1176
6a3bceb1
PH
1177PH/02 When an IPv6 address is converted to a string for single-key lookup
1178 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1179 dots are used instead of colons so that keys in lsearch files need not
1180 contain colons. This was done some time before quoting was made available
1181 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1182 (notated using the quote facility) so as to distinguish them from IPv4
1183 keys. This meant that lookups for IP addresses in host lists did not work
1184 for iplsearch lookups.
1185
1186 This has been fixed by arranging for IPv6 addresses to be expressed with
1187 colons if the lookup type is iplsearch. This is not incompatible, because
1188 previously such lookups could never work.
1189
1190 The situation is now rather anomolous, since one *can* have colons in
1191 ordinary lsearch keys. However, making the change in all cases is
1192 incompatible and would probably break a number of configurations.

1197MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1198 conversion specification without a maximum field width, thereby enabling
1199 a rogue spamd server to cause a buffer overflow. While nobody in their
1200 right mind would setup Exim to query an untrusted spamd server, an
1201 attacker that gains access to a server running spamd could potentially
1202 exploit this vulnerability to run arbitrary code as the Exim user.

1207MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for

1210 Exim lacked permissions to read, a lookup for a key matching that

1395PH/29 SMTP synchronization checks are implemented when a command is read -
1396 there is a check that no more input is waiting when there shouldn't be

1398 some time before the response is written. In this time, more input might
1399 arrive, invalidly. So now there are extra checks after an ACL has run for
1400 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1401 pipelining has not been advertised.

PH
1475 the response to the final '.' that terminates a message, but only in the
1476 case where the client has not sent further data following the '.'
1477 (unfortunately, this is allowed). However, in many cases there won't be
1478 any further data because there won't be any more messages to send. A call
1479 to select() can be used: if it shows that the input is "ready", there is
1480 either input waiting, or the socket has been closed. An attempt to read
1481 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1482 would have sent an OK response which the client would never have see.

1493PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1494 fixed by 4.65/MH/01 (is this a record?) are fixed:
1495
1496 (i) An empty string was always treated as zero by the numeric comparison
1497 operators. This behaviour has been restored.
1498
1499 (ii) It is documented that the numeric comparison operators always treat
1500 their arguments as decimal numbers. This was broken in that numbers
1501 starting with 0 were being interpreted as octal.
1502
1503 While fixing these problems I realized that there was another issue that
1504 hadn't been noticed. Values of message_size_limit (both the global option
1505 and the transport option) were treated as octal if they started with 0.
1506 The documentation was vague. These values are now always treated as
1507 decimal, and I will make that clear in the documentation.

PH
1551PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1552 callout verification, Exim cached a "reject" for the entire domain. This
1553 is correct for most verifications, but it is not correct for a recipient
1554 verification with use_sender or use_postmaster set, because in that case
1555 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1556 case of MAIL FROM:<> rejection from other early rejections (e.g.
1557 rejection of HELO). When verifying a recipient using a non-null MAIL
1558 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1559 Whatever the result of the callout, the value of the domain cache is
1560 left unchanged (for any other kind of callout, getting as far as trying
1561 RCPT means that the domain itself is ok).

PH
1595PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1596 hostname. This is wrong, because it relates to the incoming message (and
1597 probably the interface on which it is arriving) and not to the outgoing
1598 callout (which could be using a different interface). This has been
1599 changed to use the value of the helo_data option from the smtp transport
1600 instead - this is what is used when a message is actually being sent. If
1601 there is no remote transport (possible with a router that sets up host
1602 addresses), $smtp_active_hostname is used.

14aa5a05 1604PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1605 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1606 (a) The code assumed that strncpy() returns a negative number on buffer
1607 overflow, which isn't the case. Replaced with Exim's string_format()
1608 function.
1609 (b) There were several signed/unsigned issues. I just did the minimum
1610 hacking in of casts. There is scope for a larger refactoring.
1611 (c) The code used strcasecmp() which is not a standard C function.
1612 Replaced with Exim's strcmpic() function.
1613 (d) The code set only $1; it now sets $auth1 as well.
1614 (e) A simple test gave the error "authentication client didn't specify
1615 service in request". It would seem that Dovecot has changed its
1616 interface. Fortunately there's a specification; I followed it and
1617 changed what the client sends and it appears to be working now.

PH
1622PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1623 address A is aliased to B and C, where B exists and C does not. Without
1624 -v the output is "A verified" because verification stops after a
1625 successful redirection if more than one address is generated. However,
1626 with -v the child addresses are also verified. Exim was outputting "A
1627 failed to verify" and then showing the successful verification for C,
1628 with its parentage. It now outputs "B failed to verify", showing B's
1629 parentage before showing the successful verification of C.

PH
1631PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1632 look up a TXT record in a specific list after matching in a combined
1633 list.
1634
322050c2
PH
1635PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1636 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1637 they consult the DNS. I had assumed they would set it the way they
1638 wanted; and indeed my experiments on Linux seem to show that in some
1639 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1640 To be on the safe side, however, I have now made the interface to
1641 host_find_byname() similar to host_find_bydns(), with an argument
1642 containing the DNS resolver options. The host_find_byname() function now
1643 sets these options at its start, just as host_find_bydns() does. The smtp
1644 transport options dns_qualify_single and dns_search_parents are passed to
1645 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1646 of host_find_byname() use the default settings of RES_DEFNAMES
1647 (qualify_single) but not RES_DNSRCH (search_parents).
1648
08955dd3
PH
1649PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1650 spool_read_header() do less string testing, by means of a preliminary
1651 switch on the second character of optional "-foo" lines. (This is
1652 overdue, caused by the large number of possibilities that now exist.
1653 Originally there were few.) While I was there, I also converted the
1654 str(n)cmp tests so they don't re-test the leading "-" and the first
1655 character, in the hope this might squeeze out yet more improvement.
1656
1eccaa59
PH
1657PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1658 flag allowing group syntax was set by the header_syntax check but not
1659 turned off, possible causing trouble later; (2) The flag was not being
1660 set at all for the header_verify test, causing "group"-style headers to
1661 be rejected. I have now set it in this case, and also caused header_
1662 verify to ignore an empty address taken from a group. While doing this, I
1663 came across some other cases where the code for allowing group syntax
1664 while scanning a header line wasn't quite right (mostly, not resetting
1665 the flag correctly in the right place). These bugs could have caused
1666 trouble for malformed header lines. I hope it is now all correct.
1667
602e59e5
PH
1668PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1669 with the "reply" argument non-NULL. The code, however (which originally
1670 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1671 but it didn't always do it. This confused somebody who was copying the
1672 code for some other use. I have removed all the tests.
1673
411ef850
PH
1674PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1675 feature that was used to support insecure browsers during the U.S. crypto
1676 embargo. It requires special client support, and Exim is probably the
1677 only MTA that supported it -- and would never use it because real RSA is
1678 always available. This code has been removed, because it had the bad
1679 effect of slowing Exim down by computing (never used) parameters for the
1680 RSA_EXPORT functionality.
1681
7befa435
PH
1682PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1683 authenticator to fail if there's a tab character in the incoming data
1684 (there should never be unless someone is messing about, as it's supposed
1685 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1686 if the connection is using TLS or if the remote IP is the same as the
1687 local IP, and the "valid-client-cert option" if a client certificate has
1688 been verified.
1689

PH
1719
1720PH/30 Exim was sometimes attempting to deliver messages that had suffered
1721 address errors (4xx response to RCPT) over the same connection as other
1722 messages routed to the same hosts. Such deliveries are always "forced",
1723 so retry times are not inspected. This resulted in far too many retries
1724 for the affected addresses. The effect occurred only when there were more
1725 hosts than the hosts_max_try setting in the smtp transport when it had
1726 the 4xx errors. Those hosts that it had tried were not added to the list
1727 of hosts for which the message was waiting, so if all were tried, there
1728 was no problem. Two fixes have been applied:
1729
1730 (i) If there are any address or message errors in an SMTP delivery, none
1731 of the hosts (tried or untried) are now added to the list of hosts
1732 for which the message is waiting, so the message should not be a
1733 candidate for sending over the same connection that was used for a
1734 successful delivery of some other message. This seems entirely
1735 reasonable: after all the message is NOT "waiting for some host".
1736 This is so "obvious" that I'm not sure why it wasn't done
1737 previously. Hope I haven't missed anything, but it can't do any
1738 harm, as the worst effect is to miss an optimization.
1739
1740 (ii) If, despite (i), such a delivery is accidentally attempted, the
1741 routing retry time is respected, so at least it doesn't keep
1742 hammering the server.

PH
1757PH/35 The error "getsockname() failed: connection reset by peer" was being
1758 written to the panic log as well as the main log, but it isn't really
1759 panic-worthy as it just means the connection died rather early on. I have
1760 removed the panic log writing for the ECONNRESET error when getsockname()
1761 fails.
1762
48c7f9e2
PH
1763PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1764 runs only) independently of the message's sender address. This meant
1765 that, if the 4xx error was in fact related to the sender, a different
1766 message to the same recipient with a different sender could confuse
1767 things. In particualar, this can happen when sending to a greylisting
1768 server, but other circumstances could also provoke similar problems.
1769 I have changed the default so that the retry time for these errors is now
1770 based a combination of the sender and recipient addresses. This change
1771 can be overridden by setting address_retry_include_sender=false in the
1772 smtp transport.

2040PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2042 Unfortunately, if there is a major crisis, such as a disk failure,
2043 tcp-wrappers gives "deny", whereas what one would like would be some
2044 kind of temporary error. A kludge has been added to help with this.
2045 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2046 554 error is used if errno is still zero or contains ENOENT (which occurs
2047 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2048 451 error is used.

2084PH/01 The code for finding all the local interface addresses on a FreeBSD
2085 system running IPv6 was broken. This may well have applied to all BSD
2086 systems, as well as to others that have similar system calls. The broken
2087 code found IPv4 interfaces correctly, but gave incorrect values for the
2088 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2089 that it would not match correctly against @[] and not recognize the IPv6
2090 addresses as local.

2133 autoreply, Exim could try to deliver to a non-existent relative file

2156 (a) Failures to set uid/gid, the current directory, or a process leader
2157 in a subprocess such as that created by queryprogram now generate
2158 suitable debugging ouput when -d is set.

2168 additional section of a DNS packet that returns MX or SRV records.
2169 Instead, it always explicitly searches for A/AAAA records. This avoids
2170 major problems that occur when a DNS server includes only records of one
2171 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2172 fixed another bug: if SRV records were looked up and the corresponding
2173 address records were *not* found in the additional section, the port
2174 values from the SRV records were lost.

2176PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2184PH/19 When calculating a retry time, Exim used to measure the "time since
2185 failure" by looking at the "first failed" field in the retry record. Now
2186 it does not use this if it is later than than the arrival time of the
2187 message. Instead it uses the arrival time. This makes for better
2188 behaviour in cases where some deliveries succeed, thus re-setting the
2189 "first failed" field. An example is a quota failure for a huge message
2190 when small messages continue to be delivered. Without this change, the
2191 "time since failure" will always be short, possible causing more frequent
2192 delivery attempts for the huge message than are intended.

PH
2289PH/42 The content-scanning code uses fopen() to create files in which to put
2290 message data. Previously it was not paying any attention to the mode of
2291 the files. Exim runs with umask(0) because the rest of the code creates
2292 files with open(), and sets the required mode explicitly. Thus, these
2293 files were ending up world-writeable. This was not a big issue, because,
2294 being within the spool directory, they were not world-accessible. I have
2295 created a function called modefopen, which takes an additional mode
2296 argument. It sets umask(777), creates the file, chmods it to the required
2297 mode, then resets the umask. All the relevant calls to fopen() in the

2335
2336 (i) Exim was not creating retry information for temporary errors given

2338 was used in LMTP mode. This meant that they could be retried too
2339 frequently, and not timed out correctly.
2340
2341 (ii) Exim was setting the flag that allows error details to be returned
2342 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2343 recipients that were returned after the DATA command.
2344
2345PH/53 This is related to PH/52, but is more general: for any failing address,
2346 when detailed error information was permitted to be returned to the

2419PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2420 function verify_get_ident() calls ip_connect() to connect a socket, but
2421 if the "connect()" function timed out, ip_connect() used to close the
2422 socket. However, verify_get_ident() also closes the socket later, and in
2423 between Exim writes to the log, which may get opened at this point. When
2424 the socket was closed in ip_connect(), the log could get the same file
2425 descriptor number as the socket. This naturally causes chaos. The fix is
2426 not to close the socket in ip_connect(); the socket should be closed by
2427 the function that creates it. There was only one place in the code where
2428 this was missing, in the iplookup router, which I don't think anybody now
2429 uses, but I've fixed it anyway.

2452
2453 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2454 string.
2455
2456 (3) Reset the variables that are obtained from the first argument of
2457 ${prvscheck and used in the second argument before leaving the code,
2458 because their memory is reclaimed, so using them afterwards may do
2459 silly things.
2460
2461 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2462 one (it's much easier than Tom thought :-).
2463
2464 (5) Because of (4), we can now allow for the use of $prvscheck_result
2465 inside the third argument.

2485PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2486 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2487 not being looked up in the rDNS to get a host name, Exim was showing the
2488 IP address twice in Received: lines, even though the IP addresses were
2489 identical. For example:
2490
2491 Received: from [1.2.3.4] (helo=[1.2.3.4])
2492
2493 However, if the real host name was known, it was omitting the HELO data
2494 if it matched the actual IP address. This has been tidied up so that it
2495 doesn't show the same IP address twice.

2521PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2523
2524 Auto-submitted: auto-generated
2525
2526 in the messages that it generates (bounce messages and others, such as
2527 warnings). In the case of bounce messages for non-SMTP mesages, there was
2528 also a typo: it was using "Auto_submitted" (underscore instead of
2529 hyphen). Since every message generated by Exim is necessarily in response
2530 to another message, thes have all been changed to:
2531
2532 Auto-Submitted: auto-replied
2533
2534 in accordance with these statements in the RFC:
2535
2536 The auto-replied keyword:
2537
2538 - SHOULD be used on messages sent in direct response to another
2539 message by an automatic process,
2540

2584PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2585 canonical form (as documented). However, after a host name lookup from
2586 the IP address, check_host() was doing a simple string comparison with
2587 addresses acquired from the DNS when checking that the found name did
2588 have the original IP as one of its addresses. Since any found IPv6
2589 addresses are likely to be in abbreviated form, the comparison could
2590 fail. Luckily, there already exists a function for doing the comparison
2591 by converting both addresses to binary, so now that is used instead of
2592 the text comparison.

2890 with the definition in sysexits.h (which is #included earlier).
2891 Fortunately, Exim does not actually use EX_OK. The code used to try to
2892 preserve the sysexits.h value, by assumimg that macro definitions were
2893 scanned for macro replacements. I have been disabused of this notion,
2894 so now the code just undefines EX_OK before #including unistd.h.

2901 doesn't have to be particularly precise.

3109
3110PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3111 that changes the way the GnuTLS parameters are stored in the cache file.
3112 The new format can be generated externally. For backward compatibility,
3113 if the data in the cache doesn't make sense, Exim assumes it has read an
3114 old-format file, and it generates new data and writes a new file. This
3115 means that you can't go back to an older release without removing the
3116 file.
3117
3118PH/03 A redirect router that has both "unseen" and "one_time" set does not
3119 work if there are any delivery delays because "one_time" forces the
3120 parent to be marked "delivered", so its unseen clone is never tried
3121 again. For this reason, Exim now forbids the simultaneous setting of
3122 these two options.
3123
3124PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3125 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3126 entry if you want to know the details. The fix, however, neglected to
3127 consider the case when local delivery batching is involved. The test for
3128 "previously delivered" was not happening when checking to see if an
3129 address could be batched with a previous (undelivered) one; under
3130 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3131 address.

3136PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3137 header_syntax) but Exim was just ignoring anything given after a slash.
3138 In particular, this caused confusion with an attempt to use "verify =
3139 reverse_host_lookup/defer_ok". An error is now given when options are
3140 supplied for verify items that do not have them. (Maybe reverse_host_
3141 lookup should have a defer_ok option, but that's a different point.)

3143PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3193PH/19 When an Exim process that is running as root has to create an Exim log
3194 file, it does so in a subprocess that runs as exim:exim so as to get the
3195 ownership right at creation (otherwise, other Exim processes might see
3196 the file with the wrong ownership). There was no test for failure of this
3197 fork() call, which would lead to the process getting stuck as it waited
3198 for a non-existent subprocess. Forks do occasionally fail when resources
3199 run out. I reviewed all the other calls to fork(); they all seem to check
3200 for failure.

3202PH/20 When checking for unexpected SMTP input at connect time (before writing

3204 from the read() function. If the client had disconnected by this time,
3205 the result was a log entry for a synchronization error with an empty
3206 string after "input=" when read() returned zero. If read() returned -1
3207 (an event I could not check), uninitialized data bytes were printed.

PH
3219PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3220 hadn't been configured. The fix is from Juergen Kreileder, who
3221 understands it better than I do:
3222
3223 "Here's what I see happening with three configured cyrus_sasl
3224 authenticators configured (plain, login, cram-md5):
3225
3226 On startup auth_cyrus_sasl_init() gets called for each of these.
3227 This means three calls to sasl_listmech() without a specified mech_list.
3228 => SASL tests which mechs of all available mechs actually work
3229 => three warnings about OTP not working
3230 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3231
3232 With the patch, sasl_listmech() also gets called three times. But now
3233 SASL's mech_list option is set to the server_mech specified in the the
3234 authenticator. Or in other words, the answer from sasl_listmech()
3235 gets limited to just the mech you're testing for (which is different
3236 for each call.)
3237 => the return list contains just 'plain' or 'login', 'cram-md5' or
3238 nothing depending on the value of ob->server_mech.
3239
3240 I've just tested the patch: Authentication still works fine,
3241 unavailable mechs specified in the exim configuration are still
3242 caught, and the auth.log warnings about OTP are gone."

3278 . Second host offers TLS and a TLS session is established;

PH
3306PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3307 the grounds that routing the same address twice would always produce the
3308 same answer. This might have been true once, but it is certainly no
3309 longer true now. Routing a child address may depend on the previous
3310 routing that produced that child. Some complicated redirection strategies
3311 went wrong when messages had multiple recipients, and made Exim's
3312 behaviour dependent on the order in which the addresses were given.
3313
3314 I have moved the duplicate checking until after the routing is complete.
3315 Exim scans the addresses that are assigned to local and remote
3316 transports, and removes any duplicates. This means that more work will be
3317 done, as duplicates will always all be routed, but duplicates are
3318 presumably rare, so I don't expect this is of any significance.
3319
3320 For deliveries to pipes, files, and autoreplies, the duplicate checking
3321 still happens during the routing process, since they are not going to be
3322 routed further.

3327 connection it has accepted, or it never writes response data. The exiscan
3328 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3329 blindly assumes that writes won't block so it may never time out."

3343PH/42 Exim no longer gives details of delivery errors for specific addresses in
3344 bounce and delay warning messages, except in certain special cases, which
3345 are as follows:
3346
3347 (a) An SMTP error message from a remote host;
3348 (b) A message specified in a :fail: redirection;
3349 (c) A message specified in a "fail" command in a system filter;
3350 (d) A message specified in a FAIL return from the queryprogram router;
3351 (e) A message specified by the cannot_route_message router option.
3352
3353 In these cases only, Exim does include the error details in bounce and
3354 warning messages. There are also a few cases where bland messages such
3355 as "unrouteable address" or "local delivery error" are given.

3363PH/45 In a pipe transport, although a timeout while waiting for the pipe
3364 process to complete was treated as a delivery failure, a timeout while
3365 writing the message to the pipe was logged, but erroneously treated as a
3366 successful delivery. Such timeouts include transport filter timeouts. For
3367 consistency with the overall process timeout, these timeouts are now
3368 treated as errors, giving rise to delivery failures by default. However,
3369 there is now a new Boolean option for the pipe transport called
3370 timeout_defer, which, if set TRUE, converts the failures into defers for
3371 both kinds of timeout. A transport filter timeout is now identified in
3372 the log output.
