11GF/01 DEFER rather than ERROR on redis cluster MOVED response.
12 When redis_servers is set to a list of > 1 element, and the Redis servers
13 in that list are in cluster configuration, convert the REDIS_REPLY_ERROR
14 case of MOVED into a DEFER case instead, thus moving the query onto the
15 next server in the list. For a cluster of N elements, all N servers must
16 be defined in redis_servers.

29JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
30 we assumed that tags in the header were well-formed, and parsed the
31 element content after inspecting only the first char of the tag.
32 Assumptions at that stage could crash the receive process on malformed
33 input.

35JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
36 While running the DKIM ACL we operate on the Permanent memory pool so that
37 variables created with "set" persist to the DATA ACL. Also (at any time)
38 DNS lookups that fail create cache records using the Permanent pool. But
39 expansions release any allocations made on the current pool - so a dnsdb
40 lookup expansion done in the DKIM ACL releases the memory used for the
41 DNS negative-cache, and bad things result. Solution is to switch to the
42 Main pool for expansions.
43 While we're in that code, add checks on the DNS cache during store_reset,
44 active in the testsuite.
45 Problem spotted, and debugging aided, by Wolfgang Breyha.

47JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
48 When none of the hosts presented to a transport match an already-open
49 connection, close it and proceed with the list. Previously we would
50 queue the message. Spotted by Lena with Yahoo, probably involving
51 round-robin DNS.

81JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as

145JH/01 Rework error string handling in TLS interface so that the caller in

JH
156JH/03 Rework the transport continued-connection mechanism: when TLS is active,
157 do not close it down and have the child transport start it up again on
158 the passed-on TCP connection. Instead, proxy the child (and any
159 subsequent ones) for TLS via a unix-domain socket channel. Logging is
160 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 161 Certificate or OCSP information. TLS cipher information is still logged.

174JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
175 Disable the session-cache too, which might reduce our load. Since we
176 currrectly use a new context for every connection, both as server and
177 client, there is no benefit for these.
178 GnuTLS appears to not support tickets server-side by default (we don't
179 call gnutls_session_ticket_enable_server()) but client side is enabled
180 by default on recent versions (3.1.3 +) unless the PFS priority string

202JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
203 case where the routing stage had gathered several addresses to send to
204 a host before calling the transport for the first, we previously failed
205 to close down TLS in the old transport process before passing the TCP
206 connection to the new process. The new one sent a STARTTLS command
207 which naturally failed, giving a failed delivery and bloating the retry
208 database. Investigation and fix prototype from Wolfgang Breyha.
209

JH
210JH/12 Fix check on SMTP command input synchronisation. Previously there were
211 false-negatives in the check that the sender had not preempted a response
212 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 213 awareness of the SMTP input buffering.

215PP/04 Add commandline_checks_require_admin option.
216 Exim drops privileges sanely, various checks such as -be aren't a
217 security problem, as long as you trust local users with access to their
218 own account. When invoked by services which pass untrusted data to
219 Exim, this might be an issue. Set this option in main configuration
220 AND make fixes to the calling application, such as using `--` to stop
221 processing options.
222
a5ffa9b4
JH
223JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
224 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
225 responses to those, into a single TLS record each way (this usually means
226 a single packet). As a side issue, smtp_enforce_sync now works on TLS
227 connections.

463JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
464 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
465 or even an in-clear connection were permitted. Now, if the host lookup
466 was dnssec and dane was requested then the host is only used if the
467 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
468 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
469 if one fails this test.

1285TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1286
1287 When a queue runner is handling a message, Exim first routes the
1288 recipient addresses, during which it prunes them based on the retry
1289 hints database. After that it attempts to deliver the message to
1290 any remaining recipients. It then updates the hints database using
1291 the retry rules.
1292
1293 So if a recipient address works intermittently, it can get repeatedly
1294 deferred at routing time. The retry hints record remains fresh so the
1295 address never reaches the final cutoff time.
1296
1297 This is a fairly common occurrence when a user is bumping up against
1298 their storage quota. Exim had some logic in its local delivery code
1299 to deal with this. However it did not apply to per-recipient defers
1300 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1301
1ddeb334
TF
1302 This change adds a proper retry rule check during routing so that the
1303 final cutoff time is checked against the message's age. We only do
1304 this check if there is an address retry record and there is not a
1305 domain retry record; this implies that previous attempts to handle
1306 the address had the retry_use_local_parts option turned on. We use
1307 this as an approximation for the destination being like a local
1308 delivery, as in LMTP.
67bd1ab3
TF
1309
1310 I suspect this new check makes the old local delivery cutoff check
1311 redundant, but I have not verified this so I left the code in place.

1319 When I ran the test suite under the user fanf2, Exim expanded
1320 the header to contain my full name, whereas it should have added
1321 a Resent-Sender: header. It erroneously treats any prefix of the
1322 username as equal to the username.

1346 Server implementation by Todd Lyons, client by JH.
1347 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
1348 config variable "prdr_enable" controls whether the server

1351 the body content is received and before the acl_smtp_data ACL.

TF
1633TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1634 lock up or crash if it happened to be inside a call to libc when it
1635 got a SIGUSR1 from exiwhat.
1636
1637 The SIGUSR1 handler appends the current process status to the process
1638 log which is later printed by exiwhat. It used to use the general
1639 purpose logging code to do this, but several functions it calls are
1640 not safe for signals.
1641
1642 The new output code in the SIGUSR1 handler is specific to the process
1643 log, and simple enough that it's easy to inspect for signal safety.
1644 Removing some special cases also simplifies the general logging code.
1645 Removing the spurious timestamps from the process log simplifies
1646 exiwhat.
1647

TF
1648TF/04 Improved ratelimit ACL condition.
1649
1650 The /noupdate option has been deprecated in favour of /readonly which
1651 has clearer semantics. The /leaky, /strict, and /readonly update modes
1652 are mutually exclusive. The update mode is no longer included in the
1653 database key; it just determines when the database is updated. (This
4c04137d 1654 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1655
1656 Exim now checks that the per_* options are used with an update mode that
1657 makes sense for the current ACL. For example, when Exim is processing a
1658 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1659 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1660 must specify per_mail/readonly. If you omit the update mode it defaults to
1661 /leaky where that makes sense (as before) or /readonly where required.
1662
1663 The /noupdate option is now undocumented but still supported for
1664 backwards compatibility. It is equivalent to /readonly except that in
1665 ACLs where /readonly is required you may specify /leaky/noupdate or
1666 /strict/noupdate which are treated the same as /readonly.
1667
1668 A useful new feature is the /count= option. This is a generalization
1669 of the per_byte option, so that you can measure the throughput of other
1670 aggregate values. For example, the per_byte option is now equivalent
1671 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1672
1673 The per_rcpt option has been generalized using the /count= mechanism
1674 (though it's more complicated than the per_byte equivalence). When it is
1675 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1676 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1677 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1678 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1679 Note that using per_rcpt with a non-readonly update mode in more than
1680 one ACL will cause the recipients to be double-counted. (The per_mail
1681 and per_byte options don't have this problem.)
1682
1683 The handling of very low rates has changed slightly. If the computed rate
1684 is less than the event's count (usually one) then this event is the first
1685 after a long gap. In this case the rate is set to the same as this event's
1686 count, so that the first message of a spam run is counted properly.
1687
1688 The major new feature is a mechanism for counting the rate of unique
1689 events. The new per_addr option counts the number of different
1690 recipients that someone has sent messages to in the last time period. It
1691 behaves like per_rcpt if all the recipient addresses are different, but
1692 duplicate recipient addresses do not increase the measured rate. Like
1693 the /count= option this is a general mechanism, so the per_addr option
1694 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1695 example, measure the rate that a client uses different sender addresses
1696 with the options per_mail/unique=$sender_address. There are further
1697 details in the main documentation.

2267-----------------
2268
2269PH/01 Another patch from the Sieve maintainer.
2270
6a3bceb1
PH
2271PH/02 When an IPv6 address is converted to a string for single-key lookup
2272 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2273 dots are used instead of colons so that keys in lsearch files need not
2274 contain colons. This was done some time before quoting was made available
2275 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2276 (notated using the quote facility) so as to distinguish them from IPv4
2277 keys. This meant that lookups for IP addresses in host lists did not work
2278 for iplsearch lookups.
2279
2280 This has been fixed by arranging for IPv6 addresses to be expressed with
2281 colons if the lookup type is iplsearch. This is not incompatible, because
2282 previously such lookups could never work.
2283
4c04137d 2284 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2285 ordinary lsearch keys. However, making the change in all cases is
2286 incompatible and would probably break a number of configurations.

2291MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2292 conversion specification without a maximum field width, thereby enabling
2293 a rogue spamd server to cause a buffer overflow. While nobody in their
2294 right mind would setup Exim to query an untrusted spamd server, an
2295 attacker that gains access to a server running spamd could potentially
2296 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2301MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2302 a directory entry by the name of the lookup key. Previously, if a
2303 symlink pointed to a non-existing file or a file in a directory that

2489PH/29 SMTP synchronization checks are implemented when a command is read -
2490 there is a check that no more input is waiting when there shouldn't be

2492 some time before the response is written. In this time, more input might
2493 arrive, invalidly. So now there are extra checks after an ACL has run for
2494 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2495 pipelining has not been advertised.

PH
2569 the response to the final '.' that terminates a message, but only in the
2570 case where the client has not sent further data following the '.'
2571 (unfortunately, this is allowed). However, in many cases there won't be
2572 any further data because there won't be any more messages to send. A call
2573 to select() can be used: if it shows that the input is "ready", there is
2574 either input waiting, or the socket has been closed. An attempt to read
2575 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2576 would have sent an OK response which the client would never have see.

2587PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2588 fixed by 4.65/MH/01 (is this a record?) are fixed:
2589
2590 (i) An empty string was always treated as zero by the numeric comparison
2591 operators. This behaviour has been restored.
2592
2593 (ii) It is documented that the numeric comparison operators always treat
2594 their arguments as decimal numbers. This was broken in that numbers
2595 starting with 0 were being interpreted as octal.
2596
2597 While fixing these problems I realized that there was another issue that
2598 hadn't been noticed. Values of message_size_limit (both the global option
2599 and the transport option) were treated as octal if they started with 0.
2600 The documentation was vague. These values are now always treated as
2601 decimal, and I will make that clear in the documentation.

2627 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
2645PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2646 callout verification, Exim cached a "reject" for the entire domain. This
2647 is correct for most verifications, but it is not correct for a recipient
2648 verification with use_sender or use_postmaster set, because in that case
2649 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2650 case of MAIL FROM:<> rejection from other early rejections (e.g.
2651 rejection of HELO). When verifying a recipient using a non-null MAIL
2652 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2653 Whatever the result of the callout, the value of the domain cache is
2654 left unchanged (for any other kind of callout, getting as far as trying
2655 RCPT means that the domain itself is ok).

2692 callout (which could be using a different interface). This has been
2693 changed to use the value of the helo_data option from the smtp transport
2694 instead - this is what is used when a message is actually being sent. If
2695 there is no remote transport (possible with a router that sets up host
2696 addresses), $smtp_active_hostname is used.

14aa5a05 2698PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2699 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2700 (a) The code assumed that strncpy() returns a negative number on buffer
2701 overflow, which isn't the case. Replaced with Exim's string_format()
2702 function.
2703 (b) There were several signed/unsigned issues. I just did the minimum
2704 hacking in of casts. There is scope for a larger refactoring.
2705 (c) The code used strcasecmp() which is not a standard C function.
2706 Replaced with Exim's strcmpic() function.
2707 (d) The code set only $1; it now sets $auth1 as well.
2708 (e) A simple test gave the error "authentication client didn't specify
2709 service in request". It would seem that Dovecot has changed its
2710 interface. Fortunately there's a specification; I followed it and
2711 changed what the client sends and it appears to be working now.

PH
2716PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2717 address A is aliased to B and C, where B exists and C does not. Without
2718 -v the output is "A verified" because verification stops after a
2719 successful redirection if more than one address is generated. However,
2720 with -v the child addresses are also verified. Exim was outputting "A
2721 failed to verify" and then showing the successful verification for C,
2722 with its parentage. It now outputs "B failed to verify", showing B's
2723 parentage before showing the successful verification of C.

PH
2725PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2726 look up a TXT record in a specific list after matching in a combined
2727 list.
2728
322050c2
PH
2729PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2730 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2731 they consult the DNS. I had assumed they would set it the way they
2732 wanted; and indeed my experiments on Linux seem to show that in some
2733 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2734 To be on the safe side, however, I have now made the interface to
2735 host_find_byname() similar to host_find_bydns(), with an argument
2736 containing the DNS resolver options. The host_find_byname() function now
2737 sets these options at its start, just as host_find_bydns() does. The smtp
2738 transport options dns_qualify_single and dns_search_parents are passed to
2739 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2740 of host_find_byname() use the default settings of RES_DEFNAMES
2741 (qualify_single) but not RES_DNSRCH (search_parents).
2742

PH
2743PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2744 spool_read_header() do less string testing, by means of a preliminary
2745 switch on the second character of optional "-foo" lines. (This is
2746 overdue, caused by the large number of possibilities that now exist.
2747 Originally there were few.) While I was there, I also converted the
2748 str(n)cmp tests so they don't re-test the leading "-" and the first
2749 character, in the hope this might squeeze out yet more improvement.
2750

PH
2751PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2752 flag allowing group syntax was set by the header_syntax check but not
2753 turned off, possible causing trouble later; (2) The flag was not being
2754 set at all for the header_verify test, causing "group"-style headers to
2755 be rejected. I have now set it in this case, and also caused header_
2756 verify to ignore an empty address taken from a group. While doing this, I
2757 came across some other cases where the code for allowing group syntax
2758 while scanning a header line wasn't quite right (mostly, not resetting
2759 the flag correctly in the right place). These bugs could have caused
2760 trouble for malformed header lines. I hope it is now all correct.
2761
602e59e5
PH
2762PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2763 with the "reply" argument non-NULL. The code, however (which originally
2764 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2765 but it didn't always do it. This confused somebody who was copying the
2766 code for some other use. I have removed all the tests.
2767
411ef850
PH
2768PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2769 feature that was used to support insecure browsers during the U.S. crypto
2770 embargo. It requires special client support, and Exim is probably the
2771 only MTA that supported it -- and would never use it because real RSA is
2772 always available. This code has been removed, because it had the bad
2773 effect of slowing Exim down by computing (never used) parameters for the
2774 RSA_EXPORT functionality.
2775
7befa435
PH
2776PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2777 authenticator to fail if there's a tab character in the incoming data
2778 (there should never be unless someone is messing about, as it's supposed
2779 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2780 if the connection is using TLS or if the remote IP is the same as the
2781 local IP, and the "valid-client-cert option" if a client certificate has
2782 been verified.
2783
48da4259 2784PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
2813
2814PH/30 Exim was sometimes attempting to deliver messages that had suffered
2815 address errors (4xx response to RCPT) over the same connection as other
2816 messages routed to the same hosts. Such deliveries are always "forced",
2817 so retry times are not inspected. This resulted in far too many retries
2818 for the affected addresses. The effect occurred only when there were more
2819 hosts than the hosts_max_try setting in the smtp transport when it had
2820 the 4xx errors. Those hosts that it had tried were not added to the list
2821 of hosts for which the message was waiting, so if all were tried, there
2822 was no problem. Two fixes have been applied:
2823
2824 (i) If there are any address or message errors in an SMTP delivery, none
2825 of the hosts (tried or untried) are now added to the list of hosts
2826 for which the message is waiting, so the message should not be a
2827 candidate for sending over the same connection that was used for a
2828 successful delivery of some other message. This seems entirely
2829 reasonable: after all the message is NOT "waiting for some host".
2830 This is so "obvious" that I'm not sure why it wasn't done
2831 previously. Hope I haven't missed anything, but it can't do any
2832 harm, as the worst effect is to miss an optimization.
2833
2834 (ii) If, despite (i), such a delivery is accidentally attempted, the
2835 routing retry time is respected, so at least it doesn't keep
2836 hammering the server.

2851PH/35 The error "getsockname() failed: connection reset by peer" was being
2852 written to the panic log as well as the main log, but it isn't really

2854 removed the panic log writing for the ECONNRESET error when getsockname()
2855 fails.
2856
48c7f9e2
PH
2857PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2858 runs only) independently of the message's sender address. This meant
2859 that, if the 4xx error was in fact related to the sender, a different
2860 message to the same recipient with a different sender could confuse
4c04137d 2861 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2862 server, but other circumstances could also provoke similar problems.
2863 I have changed the default so that the retry time for these errors is now
2864 based a combination of the sender and recipient addresses. This change
2865 can be overridden by setting address_retry_include_sender=false in the
2866 smtp transport.

3134PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
3135 "Deny" causes Exim to reject the incoming connection with a 554 error.
3136 Unfortunately, if there is a major crisis, such as a disk failure,
3137 tcp-wrappers gives "deny", whereas what one would like would be some
3138 kind of temporary error. A kludge has been added to help with this.
3139 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3140 554 error is used if errno is still zero or contains ENOENT (which occurs
3141 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
3142 451 error is used.

3164PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3165 folder from quota calculations, a direct delivery into this folder messed
3166 up the contents of the maildirsize file. This was because the regex was
3167 used only to exclude .Trash (or whatever) when the size of the mailbox
3168 was calculated. There was no check that a delivery was happening into an
3169 excluded directory. This bug has been fixed by ignoring all quota
3170 processing for deliveries into excluded directories.

3176-----------------
3177
3178PH/01 The code for finding all the local interface addresses on a FreeBSD
3179 system running IPv6 was broken. This may well have applied to all BSD
3180 systems, as well as to others that have similar system calls. The broken
3181 code found IPv4 interfaces correctly, but gave incorrect values for the
3182 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3183 that it would not match correctly against @[] and not recognize the IPv6
3184 addresses as local.

3194 invalid. However, $reply_address has leading white space removed, and all
3195 newlines turned into spaces so that the autoreply transport does not
3196 grumble.

3224PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3225 syntactically invalid From: or Reply-to: line, and a filter used this to
3226 generate an autoreply, and therefore failed to obtain an address for the
3227 autoreply, Exim could try to deliver to a non-existent relative file
3228 name, causing unrelated and misleading errors. What now happens is that
3229 it logs this as a hard delivery error, but does not attempt to create a
3230 bounce message.

3250 (a) Failures to set uid/gid, the current directory, or a process leader

3264 major problems that occur when a DNS server includes only records of one
3265 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
