6-----------------
7
8TF/01 Correctly close the server side of TLS when forking for delivery.
9
10 When a message was received over SMTP with TLS, Exim failed to clear up
11 the incoming connection properly after forking off the child process to
12 deliver the message. In some situations the subsequent outgoing
13 delivery connection happened to have the same fd number as the incoming
14 connection previously had. Exim would try to use TLS and fail, logging
15 a "Bad file descriptor" error.

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

TF
194TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
195
196 When a queue runner is handling a message, Exim first routes the
197 recipient addresses, during which it prunes them based on the retry
198 hints database. After that it attempts to deliver the message to
199 any remaining recipients. It then updates the hints database using
200 the retry rules.
201
202 So if a recipient address works intermittently, it can get repeatedly
203 deferred at routing time. The retry hints record remains fresh so the
204 address never reaches the final cutoff time.
205
206 This is a fairly common occurrence when a user is bumping up against
207 their storage quota. Exim had some logic in its local delivery code
208 to deal with this. However it did not apply to per-recipient defers
209 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
210
1ddeb334
TF
211 This change adds a proper retry rule check during routing so that the
212 final cutoff time is checked against the message's age. We only do
213 this check if there is an address retry record and there is not a
214 domain retry record; this implies that previous attempts to handle
215 the address had the retry_use_local_parts option turned on. We use
216 this as an approximation for the destination being like a local
217 delivery, as in LMTP.
67bd1ab3
TF
218
219 I suspect this new check makes the old local delivery cutoff check
220 redundant, but I have not verified this so I left the code in place.

222TF/02 Correct gecos expansion when From: is a prefix of the username.
223
224 Test 0254 submits a message to Exim with the header
225
226 Resent-From: f
227
228 When I ran the test suite under the user fanf2, Exim expanded
229 the header to contain my full name, whereas it should have added
230 a Resent-Sender: header. It erroneously treats any prefix of the
231 username as equal to the username.
232
233 This change corrects that bug.

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

274 This is now consistent with GnuTLS, and is now documented: the
275 previous undocumented portable approach to treating the option as
276 unset was to force an expansion failure. That still works, and
277 an empty string is now equivalent.

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

1156 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1157 were called 'true' and it seems that C99 defines that as a reserved
1158 keyword to be used with 'bool' variable types. That means you could
1159 not include C99-style headers which use bools without triggering
1160 build errors in sieve.c.

1177
1178PH/01 Another patch from the Sieve maintainer.
1179
6a3bceb1
PH
1180PH/02 When an IPv6 address is converted to a string for single-key lookup
1181 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1182 dots are used instead of colons so that keys in lsearch files need not
1183 contain colons. This was done some time before quoting was made available
1184 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1185 (notated using the quote facility) so as to distinguish them from IPv4
1186 keys. This meant that lookups for IP addresses in host lists did not work
1187 for iplsearch lookups.
1188
1189 This has been fixed by arranging for IPv6 addresses to be expressed with
1190 colons if the lookup type is iplsearch. This is not incompatible, because
1191 previously such lookups could never work.
1192
1193 The situation is now rather anomolous, since one *can* have colons in
1194 ordinary lsearch keys. However, making the change in all cases is
1195 incompatible and would probably break a number of configurations.

1200MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1201 conversion specification without a maximum field width, thereby enabling
1202 a rogue spamd server to cause a buffer overflow. While nobody in their
1203 right mind would setup Exim to query an untrusted spamd server, an
1204 attacker that gains access to a server running spamd could potentially
1205 exploit this vulnerability to run arbitrary code as the Exim user.

1210MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for

1213 Exim lacked permissions to read, a lookup for a key matching that

1398PH/29 SMTP synchronization checks are implemented when a command is read -
1399 there is a check that no more input is waiting when there shouldn't be

1401 some time before the response is written. In this time, more input might
1402 arrive, invalidly. So now there are extra checks after an ACL has run for
1403 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1404 pipelining has not been advertised.

1419 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1420 was a macro that became an assignment, so it seemed to work. This has

1460 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1478 the response to the final '.' that terminates a message, but only in the
1479 case where the client has not sent further data following the '.'
1480 (unfortunately, this is allowed). However, in many cases there won't be
1481 any further data because there won't be any more messages to send. A call
1482 to select() can be used: if it shows that the input is "ready", there is
1483 either input waiting, or the socket has been closed. An attempt to read
1484 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1485 would have sent an OK response which the client would never have see.

1496PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1497 fixed by 4.65/MH/01 (is this a record?) are fixed:
1498
1499 (i) An empty string was always treated as zero by the numeric comparison
1500 operators. This behaviour has been restored.
1501
1502 (ii) It is documented that the numeric comparison operators always treat
1503 their arguments as decimal numbers. This was broken in that numbers
1504 starting with 0 were being interpreted as octal.
1505
1506 While fixing these problems I realized that there was another issue that
1507 hadn't been noticed. Values of message_size_limit (both the global option
1508 and the transport option) were treated as octal if they started with 0.
1509 The documentation was vague. These values are now always treated as
1510 decimal, and I will make that clear in the documentation.

2b1c6e3a
PH
1554PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1555 callout verification, Exim cached a "reject" for the entire domain. This
1556 is correct for most verifications, but it is not correct for a recipient
1557 verification with use_sender or use_postmaster set, because in that case
1558 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1559 case of MAIL FROM:<> rejection from other early rejections (e.g.
1560 rejection of HELO). When verifying a recipient using a non-null MAIL
1561 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1562 Whatever the result of the callout, the value of the domain cache is
1563 left unchanged (for any other kind of callout, getting as far as trying
1564 RCPT means that the domain itself is ok).

1598PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1599 hostname. This is wrong, because it relates to the incoming message (and
1600 probably the interface on which it is arriving) and not to the outgoing
1601 callout (which could be using a different interface). This has been
1602 changed to use the value of the helo_data option from the smtp transport
1603 instead - this is what is used when a message is actually being sent. If
1604 there is no remote transport (possible with a router that sets up host
1605 addresses), $smtp_active_hostname is used.

14aa5a05 1607PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1608 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1609 (a) The code assumed that strncpy() returns a negative number on buffer
1610 overflow, which isn't the case. Replaced with Exim's string_format()
1611 function.
1612 (b) There were several signed/unsigned issues. I just did the minimum
1613 hacking in of casts. There is scope for a larger refactoring.
1614 (c) The code used strcasecmp() which is not a standard C function.
1615 Replaced with Exim's strcmpic() function.
1616 (d) The code set only $1; it now sets $auth1 as well.
1617 (e) A simple test gave the error "authentication client didn't specify
1618 service in request". It would seem that Dovecot has changed its
1619 interface. Fortunately there's a specification; I followed it and
1620 changed what the client sends and it appears to be working now.

PH
1625PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1626 address A is aliased to B and C, where B exists and C does not. Without
1627 -v the output is "A verified" because verification stops after a
1628 successful redirection if more than one address is generated. However,
1629 with -v the child addresses are also verified. Exim was outputting "A
1630 failed to verify" and then showing the successful verification for C,
1631 with its parentage. It now outputs "B failed to verify", showing B's
1632 parentage before showing the successful verification of C.

PH
1634PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1635 look up a TXT record in a specific list after matching in a combined
1636 list.
1637
322050c2
PH
1638PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1639 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1640 they consult the DNS. I had assumed they would set it the way they
1641 wanted; and indeed my experiments on Linux seem to show that in some
1642 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1643 To be on the safe side, however, I have now made the interface to
1644 host_find_byname() similar to host_find_bydns(), with an argument
1645 containing the DNS resolver options. The host_find_byname() function now
1646 sets these options at its start, just as host_find_bydns() does. The smtp
1647 transport options dns_qualify_single and dns_search_parents are passed to
1648 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1649 of host_find_byname() use the default settings of RES_DEFNAMES
1650 (qualify_single) but not RES_DNSRCH (search_parents).
1651

PH
1652PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1653 spool_read_header() do less string testing, by means of a preliminary
1654 switch on the second character of optional "-foo" lines. (This is
1655 overdue, caused by the large number of possibilities that now exist.
1656 Originally there were few.) While I was there, I also converted the
1657 str(n)cmp tests so they don't re-test the leading "-" and the first
1658 character, in the hope this might squeeze out yet more improvement.
1659

PH
1660PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1661 flag allowing group syntax was set by the header_syntax check but not
1662 turned off, possible causing trouble later; (2) The flag was not being
1663 set at all for the header_verify test, causing "group"-style headers to
1664 be rejected. I have now set it in this case, and also caused header_
1665 verify to ignore an empty address taken from a group. While doing this, I
1666 came across some other cases where the code for allowing group syntax
1667 while scanning a header line wasn't quite right (mostly, not resetting
1668 the flag correctly in the right place). These bugs could have caused
1669 trouble for malformed header lines. I hope it is now all correct.
1670
602e59e5
PH
1671PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1672 with the "reply" argument non-NULL. The code, however (which originally
1673 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1674 but it didn't always do it. This confused somebody who was copying the
1675 code for some other use. I have removed all the tests.
1676
411ef850
PH
1677PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1678 feature that was used to support insecure browsers during the U.S. crypto
1679 embargo. It requires special client support, and Exim is probably the
1680 only MTA that supported it -- and would never use it because real RSA is
1681 always available. This code has been removed, because it had the bad
1682 effect of slowing Exim down by computing (never used) parameters for the
1683 RSA_EXPORT functionality.
1684
7befa435
PH
1685PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1686 authenticator to fail if there's a tab character in the incoming data
1687 (there should never be unless someone is messing about, as it's supposed
1688 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1689 if the connection is using TLS or if the remote IP is the same as the
1690 local IP, and the "valid-client-cert option" if a client certificate has
1691 been verified.

1722
1723PH/30 Exim was sometimes attempting to deliver messages that had suffered
1724 address errors (4xx response to RCPT) over the same connection as other
1725 messages routed to the same hosts. Such deliveries are always "forced",
1726 so retry times are not inspected. This resulted in far too many retries
1727 for the affected addresses. The effect occurred only when there were more
1728 hosts than the hosts_max_try setting in the smtp transport when it had
1729 the 4xx errors. Those hosts that it had tried were not added to the list
1730 of hosts for which the message was waiting, so if all were tried, there
1731 was no problem. Two fixes have been applied:
1732
1733 (i) If there are any address or message errors in an SMTP delivery, none
1734 of the hosts (tried or untried) are now added to the list of hosts
1735 for which the message is waiting, so the message should not be a
1736 candidate for sending over the same connection that was used for a
1737 successful delivery of some other message. This seems entirely
1738 reasonable: after all the message is NOT "waiting for some host".
1739 This is so "obvious" that I'm not sure why it wasn't done
1740 previously. Hope I haven't missed anything, but it can't do any
1741 harm, as the worst effect is to miss an optimization.
1742
1743 (ii) If, despite (i), such a delivery is accidentally attempted, the
1744 routing retry time is respected, so at least it doesn't keep
1745 hammering the server.

1760PH/35 The error "getsockname() failed: connection reset by peer" was being
1761 written to the panic log as well as the main log, but it isn't really
1762 panic-worthy as it just means the connection died rather early on. I have
1763 removed the panic log writing for the ECONNRESET error when getsockname()
1764 fails.
1765
48c7f9e2
PH
1766PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1767 runs only) independently of the message's sender address. This meant
1768 that, if the 4xx error was in fact related to the sender, a different
1769 message to the same recipient with a different sender could confuse
1770 things. In particualar, this can happen when sending to a greylisting
1771 server, but other circumstances could also provoke similar problems.
1772 I have changed the default so that the retry time for these errors is now
1773 based a combination of the sender and recipient addresses. This change
1774 can be overridden by setting address_retry_include_sender=false in the
1775 smtp transport.

2043PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2045 Unfortunately, if there is a major crisis, such as a disk failure,
2046 tcp-wrappers gives "deny", whereas what one would like would be some
2047 kind of temporary error. A kludge has been added to help with this.
2048 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2049 554 error is used if errno is still zero or contains ENOENT (which occurs
2050 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2051 451 error is used.

2087PH/01 The code for finding all the local interface addresses on a FreeBSD
2088 system running IPv6 was broken. This may well have applied to all BSD
2089 systems, as well as to others that have similar system calls. The broken
2090 code found IPv4 interfaces correctly, but gave incorrect values for the
2091 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2092 that it would not match correctly against @[] and not recognize the IPv6
2093 addresses as local.

2136 autoreply, Exim could try to deliver to a non-existent relative file

2160 in a subprocess such as that created by queryprogram now generate
2161 suitable debugging ouput when -d is set.

2172 Instead, it always explicitly searches for A/AAAA records. This avoids
2173 major problems that occur when a DNS server includes only records of one
2174 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2175 fixed another bug: if SRV records were looked up and the corresponding
2176 address records were *not* found in the additional section, the port
2177 values from the SRV records were lost.

2179PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2187PH/19 When calculating a retry time, Exim used to measure the "time since
2188 failure" by looking at the "first failed" field in the retry record. Now
2189 it does not use this if it is later than than the arrival time of the
2190 message. Instead it uses the arrival time. This makes for better
2191 behaviour in cases where some deliveries succeed, thus re-setting the
2192 "first failed" field. An example is a quota failure for a huge message
2193 when small messages continue to be delivered. Without this change, the
2194 "time since failure" will always be short, possible causing more frequent
2195 delivery attempts for the huge message than are intended.

2292PH/42 The content-scanning code uses fopen() to create files in which to put

2294 the files. Exim runs with umask(0) because the rest of the code creates
2295 files with open(), and sets the required mode explicitly. Thus, these
2296 files were ending up world-writeable. This was not a big issue, because,
2297 being within the spool directory, they were not world-accessible. I have
2298 created a function called modefopen, which takes an additional mode
2299 argument. It sets umask(777), creates the file, chmods it to the required
2300 mode, then resets the umask. All the relevant calls to fopen() in the

2338
2339 (i) Exim was not creating retry information for temporary errors given

2341 was used in LMTP mode. This meant that they could be retried too
2342 frequently, and not timed out correctly.
2343
2344 (ii) Exim was setting the flag that allows error details to be returned
2345 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2346 recipients that were returned after the DATA command.
2347
2348PH/53 This is related to PH/52, but is more general: for any failing address,
2349 when detailed error information was permitted to be returned to the

2422PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2423 function verify_get_ident() calls ip_connect() to connect a socket, but
2424 if the "connect()" function timed out, ip_connect() used to close the
2425 socket. However, verify_get_ident() also closes the socket later, and in
2426 between Exim writes to the log, which may get opened at this point. When
2427 the socket was closed in ip_connect(), the log could get the same file
2428 descriptor number as the socket. This naturally causes chaos. The fix is
2429 not to close the socket in ip_connect(); the socket should be closed by
2430 the function that creates it. There was only one place in the code where
2431 this was missing, in the iplookup router, which I don't think anybody now
2432 uses, but I've fixed it anyway.

2455
2456 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2457 string.
2458
2459 (3) Reset the variables that are obtained from the first argument of
2460 ${prvscheck and used in the second argument before leaving the code,
2461 because their memory is reclaimed, so using them afterwards may do
2462 silly things.
2463
2464 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2465 one (it's much easier than Tom thought :-).
2466
2467 (5) Because of (4), we can now allow for the use of $prvscheck_result

2483 may be more than one such address. If so, they are comma-separated, like

2488PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2489 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2490 not being looked up in the rDNS to get a host name, Exim was showing the
2491 IP address twice in Received: lines, even though the IP addresses were
2492 identical. For example:
2493
2494 Received: from [1.2.3.4] (helo=[1.2.3.4])
2495
2496 However, if the real host name was known, it was omitting the HELO data
2497 if it matched the actual IP address. This has been tidied up so that it
2498 doesn't show the same IP address twice.

2524PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2526
2527 Auto-submitted: auto-generated
2528
2529 in the messages that it generates (bounce messages and others, such as
2530 warnings). In the case of bounce messages for non-SMTP mesages, there was
2531 also a typo: it was using "Auto_submitted" (underscore instead of
2532 hyphen). Since every message generated by Exim is necessarily in response
2533 to another message, thes have all been changed to:
2534
2535 Auto-Submitted: auto-replied
2536
2537 in accordance with these statements in the RFC:
2538
2539 The auto-replied keyword:
2540
2541 - SHOULD be used on messages sent in direct response to another
2542 message by an automatic process,
2543

2547 Disposition Notifications (MDNs),

2587PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2588 canonical form (as documented). However, after a host name lookup from
2589 the IP address, check_host() was doing a simple string comparison with
2590 addresses acquired from the DNS when checking that the found name did
2591 have the original IP as one of its addresses. Since any found IPv6
2592 addresses are likely to be in abbreviated form, the comparison could
2593 fail. Luckily, there already exists a function for doing the comparison
2594 by converting both addresses to binary, so now that is used instead of
2595 the text comparison.

2597PH/20 There was another similar case to PH/19, when a complete host name was

2893 with the definition in sysexits.h (which is #included earlier).
2894 Fortunately, Exim does not actually use EX_OK. The code used to try to
2895 preserve the sysexits.h value, by assumimg that macro definitions were
2896 scanned for macro replacements. I have been disabused of this notion,

2902 This seems wrong - if the receiver was accepting one byte at a time it
2903 would take for ever. The timeout is now adjusted when this happens. It
2904 doesn't have to be particularly precise.

2981 suddenly stopped working when I started to use syslog. The patch checks

3113PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3114 that changes the way the GnuTLS parameters are stored in the cache file.
3115 The new format can be generated externally. For backward compatibility,
3116 if the data in the cache doesn't make sense, Exim assumes it has read an
3117 old-format file, and it generates new data and writes a new file. This
3118 means that you can't go back to an older release without removing the
3119 file.
3120
3121PH/03 A redirect router that has both "unseen" and "one_time" set does not
3122 work if there are any delivery delays because "one_time" forces the
3123 parent to be marked "delivered", so its unseen clone is never tried
3124 again. For this reason, Exim now forbids the simultaneous setting of
3125 these two options.
3126
3127PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3128 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3129 entry if you want to know the details. The fix, however, neglected to
3130 consider the case when local delivery batching is involved. The test for
3131 "previously delivered" was not happening when checking to see if an
3132 address could be batched with a previous (undelivered) one; under
3133 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3134 address.

3139PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3140 header_syntax) but Exim was just ignoring anything given after a slash.
3141 In particular, this caused confusion with an attempt to use "verify =
3142 reverse_host_lookup/defer_ok". An error is now given when options are
3143 supplied for verify items that do not have them. (Maybe reverse_host_
3144 lookup should have a defer_ok option, but that's a different point.)

3146PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3196PH/19 When an Exim process that is running as root has to create an Exim log
3197 file, it does so in a subprocess that runs as exim:exim so as to get the
3198 ownership right at creation (otherwise, other Exim processes might see
3199 the file with the wrong ownership). There was no test for failure of this
3200 fork() call, which would lead to the process getting stuck as it waited
3201 for a non-existent subprocess. Forks do occasionally fail when resources
3202 run out. I reviewed all the other calls to fork(); they all seem to check
3203 for failure.

3205PH/20 When checking for unexpected SMTP input at connect time (before writing
3206 the banner), Exim was not dealing correctly with a non-positive return
3207 from the read() function. If the client had disconnected by this time,
3208 the result was a log entry for a synchronization error with an empty
3209 string after "input=" when read() returned zero. If read() returned -1
3210 (an event I could not check), uninitialized data bytes were printed.
3211 There were reports of junk text (parts of files, etc) appearing after
3212 "input=".

3220 forgetting to use the resulting value; it was using the unexpanded value.
3221
c5ddb310
PH
3222PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3223 hadn't been configured. The fix is from Juergen Kreileder, who
3224 understands it better than I do:
3225
3226 "Here's what I see happening with three configured cyrus_sasl
3227 authenticators configured (plain, login, cram-md5):
3228
3229 On startup auth_cyrus_sasl_init() gets called for each of these.
3230 This means three calls to sasl_listmech() without a specified mech_list.
3231 => SASL tests which mechs of all available mechs actually work
3232 => three warnings about OTP not working
3233 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3234
3235 With the patch, sasl_listmech() also gets called three times. But now
3236 SASL's mech_list option is set to the server_mech specified in the the
3237 authenticator. Or in other words, the answer from sasl_listmech()
3238 gets limited to just the mech you're testing for (which is different
3239 for each call.)
3240 => the return list contains just 'plain' or 'login', 'cram-md5' or
3241 nothing depending on the value of ob->server_mech.
3242
3243 I've just tested the patch: Authentication still works fine,
3244 unavailable mechs specified in the exim configuration are still
3245 caught, and the auth.log warnings about OTP are gone."

3255PH/27 $acl_verify_message is now set immediately after the failure of a

3277 . Two addresses routed to the same list of hosts;

3280 . First host gives temporary error to second address;
3281 . Second host offers TLS and a TLS session is established;
3282 . Second host accepts second address.
3283 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3284 and peerdn, if requested) that were in fact used only for the second
3285 address.

3290 does for delivery: the affixes are removed from the local part unless

PH
3309PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3310 the grounds that routing the same address twice would always produce the
3311 same answer. This might have been true once, but it is certainly no
3312 longer true now. Routing a child address may depend on the previous
3313 routing that produced that child. Some complicated redirection strategies
3314 went wrong when messages had multiple recipients, and made Exim's
3315 behaviour dependent on the order in which the addresses were given.
3316
3317 I have moved the duplicate checking until after the routing is complete.
3318 Exim scans the addresses that are assigned to local and remote
3319 transports, and removes any duplicates. This means that more work will be
3320 done, as duplicates will always all be routed, but duplicates are
3321 presumably rare, so I don't expect this is of any significance.
3322
3323 For deliveries to pipes, files, and autoreplies, the duplicate checking
3324 still happens during the routing process, since they are not going to be
3325 routed further.

3327PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3328 It corrects a timeout issue with spamd. This is Ian's comment: "The
3329 background is that sometimes spamd either never reads data from a
3330 connection it has accepted, or it never writes response data. The exiscan
3331 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3332 blindly assumes that writes won't block so it may never time out."

3346PH/42 Exim no longer gives details of delivery errors for specific addresses in
3347 bounce and delay warning messages, except in certain special cases, which
3348 are as follows:
3349
3350 (a) An SMTP error message from a remote host;
3351 (b) A message specified in a :fail: redirection;
3352 (c) A message specified in a "fail" command in a system filter;
3353 (d) A message specified in a FAIL return from the queryprogram router;
3354 (e) A message specified by the cannot_route_message router option.
3355
3356 In these cases only, Exim does include the error details in bounce and
3357 warning messages. There are also a few cases where bland messages such
3358 as "unrouteable address" or "local delivery error" are given.

PH
3366PH/45 In a pipe transport, although a timeout while waiting for the pipe
3367 process to complete was treated as a delivery failure, a timeout while
3368 writing the message to the pipe was logged, but erroneously treated as a
3369 successful delivery. Such timeouts include transport filter timeouts. For
3370 consistency with the overall process timeout, these timeouts are now
3371 treated as errors, giving rise to delivery failures by default. However,
3372 there is now a new Boolean option for the pipe transport called
3373 timeout_defer, which, if set TRUE, converts the failures into defers for
3374 both kinds of timeout. A transport filter timeout is now identified in
3375 the log output.
