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.

18JH/01 Replace the store_release() internal interface with store_newblock(),

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.

JH
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.

71JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
72 SMTP connection. Previously, when one had more receipients than the
73 first, an abortive onward connection was made. Move to full support for
74 multiple onward connections in sequence, handling cutthrough connection
75 for all multi-message initiating connections.

81JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
82 a timeout on read on a GnuTLS initiating connection, resulting in the

84 was marked defer_ok. Fix to keep the two timeout-detection methods
85 separate.

148JH/01 Rework error string handling in TLS interface so that the caller in

JH
159JH/03 Rework the transport continued-connection mechanism: when TLS is active,
160 do not close it down and have the child transport start it up again on
161 the passed-on TCP connection. Instead, proxy the child (and any
162 subsequent ones) for TLS via a unix-domain socket channel. Logging is
163 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 164 Certificate or OCSP information. TLS cipher information is still logged.

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

205JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
206 case where the routing stage had gathered several addresses to send to
207 a host before calling the transport for the first, we previously failed
208 to close down TLS in the old transport process before passing the TCP
209 connection to the new process. The new one sent a STARTTLS command
210 which naturally failed, giving a failed delivery and bloating the retry
211 database. Investigation and fix prototype from Wolfgang Breyha.
212

JH
213JH/12 Fix check on SMTP command input synchronisation. Previously there were
214 false-negatives in the check that the sender had not preempted a response
215 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 216 awareness of the SMTP input buffering.

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

402 Fast Open mode on its listening sockets. This fixes breakage seen on
403 too-old kernels or those not configured for Fast Open, at the cost of
404 requiring both directions being enabled for TFO, and TFO never being used
405 by non-daemon-related Exim processes.

466JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
467 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
468 or even an in-clear connection were permitted. Now, if the host lookup
469 was dnssec and dane was requested then the host is only used if the
470 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
471 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
472 if one fails this test.
473 This means that a poorly-configured remote DNS will make it incommunicado;
474 but it protects against a DNS-interception attack on it.

1288TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1289
1290 When a queue runner is handling a message, Exim first routes the
1291 recipient addresses, during which it prunes them based on the retry
1292 hints database. After that it attempts to deliver the message to
1293 any remaining recipients. It then updates the hints database using
1294 the retry rules.
1295
1296 So if a recipient address works intermittently, it can get repeatedly
1297 deferred at routing time. The retry hints record remains fresh so the
1298 address never reaches the final cutoff time.
1299
1300 This is a fairly common occurrence when a user is bumping up against
1301 their storage quota. Exim had some logic in its local delivery code
1302 to deal with this. However it did not apply to per-recipient defers
1303 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1304
1ddeb334
TF
1305 This change adds a proper retry rule check during routing so that the
1306 final cutoff time is checked against the message's age. We only do
1307 this check if there is an address retry record and there is not a
1308 domain retry record; this implies that previous attempts to handle
1309 the address had the retry_use_local_parts option turned on. We use
1310 this as an approximation for the destination being like a local
1311 delivery, as in LMTP.
67bd1ab3
TF
1312
1313 I suspect this new check makes the old local delivery cutoff check
1314 redundant, but I have not verified this so I left the code in place.

1323 the header to contain my full name, whereas it should have added
1324 a Resent-Sender: header. It erroneously treats any prefix of the
1325 username as equal to the username.

1354 the body content is received and before the acl_smtp_data ACL.

1636TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1637 lock up or crash if it happened to be inside a call to libc when it
1638 got a SIGUSR1 from exiwhat.
1639
1640 The SIGUSR1 handler appends the current process status to the process
1641 log which is later printed by exiwhat. It used to use the general
1642 purpose logging code to do this, but several functions it calls are
1643 not safe for signals.
1644
1645 The new output code in the SIGUSR1 handler is specific to the process
1646 log, and simple enough that it's easy to inspect for signal safety.
1647 Removing some special cases also simplifies the general logging code.
1648 Removing the spurious timestamps from the process log simplifies
1649 exiwhat.

c99ce5c9
TF
1651TF/04 Improved ratelimit ACL condition.
1652
1653 The /noupdate option has been deprecated in favour of /readonly which
1654 has clearer semantics. The /leaky, /strict, and /readonly update modes
1655 are mutually exclusive. The update mode is no longer included in the
1656 database key; it just determines when the database is updated. (This
4c04137d 1657 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1658
1659 Exim now checks that the per_* options are used with an update mode that
1660 makes sense for the current ACL. For example, when Exim is processing a
1661 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1662 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1663 must specify per_mail/readonly. If you omit the update mode it defaults to
1664 /leaky where that makes sense (as before) or /readonly where required.
1665
1666 The /noupdate option is now undocumented but still supported for
1667 backwards compatibility. It is equivalent to /readonly except that in
1668 ACLs where /readonly is required you may specify /leaky/noupdate or
1669 /strict/noupdate which are treated the same as /readonly.
1670
1671 A useful new feature is the /count= option. This is a generalization
1672 of the per_byte option, so that you can measure the throughput of other
1673 aggregate values. For example, the per_byte option is now equivalent
1674 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1675
1676 The per_rcpt option has been generalized using the /count= mechanism
1677 (though it's more complicated than the per_byte equivalence). When it is
1678 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1679 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1680 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1681 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1682 Note that using per_rcpt with a non-readonly update mode in more than
1683 one ACL will cause the recipients to be double-counted. (The per_mail
1684 and per_byte options don't have this problem.)
1685
1686 The handling of very low rates has changed slightly. If the computed rate
1687 is less than the event's count (usually one) then this event is the first
1688 after a long gap. In this case the rate is set to the same as this event's
1689 count, so that the first message of a spam run is counted properly.
1690
1691 The major new feature is a mechanism for counting the rate of unique
1692 events. The new per_addr option counts the number of different
1693 recipients that someone has sent messages to in the last time period. It
1694 behaves like per_rcpt if all the recipient addresses are different, but
1695 duplicate recipient addresses do not increase the measured rate. Like
1696 the /count= option this is a general mechanism, so the per_addr option
1697 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1698 example, measure the rate that a client uses different sender addresses
1699 with the options per_mail/unique=$sender_address. There are further
1700 details in the main documentation.

2271
2272PH/01 Another patch from the Sieve maintainer.
2273
6a3bceb1
PH
2274PH/02 When an IPv6 address is converted to a string for single-key lookup
2275 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2276 dots are used instead of colons so that keys in lsearch files need not
2277 contain colons. This was done some time before quoting was made available
2278 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2279 (notated using the quote facility) so as to distinguish them from IPv4
2280 keys. This meant that lookups for IP addresses in host lists did not work
2281 for iplsearch lookups.
2282
2283 This has been fixed by arranging for IPv6 addresses to be expressed with
2284 colons if the lookup type is iplsearch. This is not incompatible, because
2285 previously such lookups could never work.
2286
4c04137d 2287 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2288 ordinary lsearch keys. However, making the change in all cases is
2289 incompatible and would probably break a number of configurations.

2294MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2295 conversion specification without a maximum field width, thereby enabling
2296 a rogue spamd server to cause a buffer overflow. While nobody in their
2297 right mind would setup Exim to query an untrusted spamd server, an
2298 attacker that gains access to a server running spamd could potentially
2299 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2304MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2305 a directory entry by the name of the lookup key. Previously, if a
2306 symlink pointed to a non-existing file or a file in a directory that

2492PH/29 SMTP synchronization checks are implemented when a command is read -
2493 there is a check that no more input is waiting when there shouldn't be

2495 some time before the response is written. In this time, more input might
2496 arrive, invalidly. So now there are extra checks after an ACL has run for
2497 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2498 pipelining has not been advertised.

2554 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2572 the response to the final '.' that terminates a message, but only in the
2573 case where the client has not sent further data following the '.'
2574 (unfortunately, this is allowed). However, in many cases there won't be
2575 any further data because there won't be any more messages to send. A call
2576 to select() can be used: if it shows that the input is "ready", there is
2577 either input waiting, or the socket has been closed. An attempt to read
2578 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2579 would have sent an OK response which the client would never have see.

2590PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2591 fixed by 4.65/MH/01 (is this a record?) are fixed:
2592
2593 (i) An empty string was always treated as zero by the numeric comparison
2594 operators. This behaviour has been restored.
2595
2596 (ii) It is documented that the numeric comparison operators always treat
2597 their arguments as decimal numbers. This was broken in that numbers
2598 starting with 0 were being interpreted as octal.
2599
2600 While fixing these problems I realized that there was another issue that
2601 hadn't been noticed. Values of message_size_limit (both the global option
2602 and the transport option) were treated as octal if they started with 0.
2603 The documentation was vague. These values are now always treated as
2604 decimal, and I will make that clear in the documentation.

2621 large number of recipients for a single message is ridiculous
2622 (performance will be very, very poor), I have chosen to impose a limit
2623 rather than extend the field.

2629TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2630 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
2648PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2649 callout verification, Exim cached a "reject" for the entire domain. This
2650 is correct for most verifications, but it is not correct for a recipient
2651 verification with use_sender or use_postmaster set, because in that case
2652 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2653 case of MAIL FROM:<> rejection from other early rejections (e.g.
2654 rejection of HELO). When verifying a recipient using a non-null MAIL
2655 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2656 Whatever the result of the callout, the value of the domain cache is
2657 left unchanged (for any other kind of callout, getting as far as trying
2658 RCPT means that the domain itself is ok).

2695 callout (which could be using a different interface). This has been
2696 changed to use the value of the helo_data option from the smtp transport
2697 instead - this is what is used when a message is actually being sent. If
2698 there is no remote transport (possible with a router that sets up host
2699 addresses), $smtp_active_hostname is used.

14aa5a05 2701PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2702 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2703 (a) The code assumed that strncpy() returns a negative number on buffer
2704 overflow, which isn't the case. Replaced with Exim's string_format()
2705 function.
2706 (b) There were several signed/unsigned issues. I just did the minimum
2707 hacking in of casts. There is scope for a larger refactoring.
2708 (c) The code used strcasecmp() which is not a standard C function.
2709 Replaced with Exim's strcmpic() function.
2710 (d) The code set only $1; it now sets $auth1 as well.
2711 (e) A simple test gave the error "authentication client didn't specify
2712 service in request". It would seem that Dovecot has changed its
2713 interface. Fortunately there's a specification; I followed it and
2714 changed what the client sends and it appears to be working now.

e6f6568e
PH
2719PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2720 address A is aliased to B and C, where B exists and C does not. Without
2721 -v the output is "A verified" because verification stops after a
2722 successful redirection if more than one address is generated. However,
2723 with -v the child addresses are also verified. Exim was outputting "A
2724 failed to verify" and then showing the successful verification for C,
2725 with its parentage. It now outputs "B failed to verify", showing B's
2726 parentage before showing the successful verification of C.

PH
2728PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2729 look up a TXT record in a specific list after matching in a combined
2730 list.
2731
322050c2
PH
2732PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2733 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2734 they consult the DNS. I had assumed they would set it the way they
2735 wanted; and indeed my experiments on Linux seem to show that in some
2736 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2737 To be on the safe side, however, I have now made the interface to
2738 host_find_byname() similar to host_find_bydns(), with an argument
2739 containing the DNS resolver options. The host_find_byname() function now
2740 sets these options at its start, just as host_find_bydns() does. The smtp
2741 transport options dns_qualify_single and dns_search_parents are passed to
2742 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2743 of host_find_byname() use the default settings of RES_DEFNAMES
2744 (qualify_single) but not RES_DNSRCH (search_parents).
2745

PH
2746PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2747 spool_read_header() do less string testing, by means of a preliminary
2748 switch on the second character of optional "-foo" lines. (This is
2749 overdue, caused by the large number of possibilities that now exist.
2750 Originally there were few.) While I was there, I also converted the
2751 str(n)cmp tests so they don't re-test the leading "-" and the first
2752 character, in the hope this might squeeze out yet more improvement.
2753

PH
2754PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2755 flag allowing group syntax was set by the header_syntax check but not
2756 turned off, possible causing trouble later; (2) The flag was not being
2757 set at all for the header_verify test, causing "group"-style headers to
2758 be rejected. I have now set it in this case, and also caused header_
2759 verify to ignore an empty address taken from a group. While doing this, I
2760 came across some other cases where the code for allowing group syntax
2761 while scanning a header line wasn't quite right (mostly, not resetting
2762 the flag correctly in the right place). These bugs could have caused
2763 trouble for malformed header lines. I hope it is now all correct.
2764
602e59e5
PH
2765PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2766 with the "reply" argument non-NULL. The code, however (which originally
2767 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2768 but it didn't always do it. This confused somebody who was copying the
2769 code for some other use. I have removed all the tests.
2770
411ef850
PH
2771PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2772 feature that was used to support insecure browsers during the U.S. crypto
2773 embargo. It requires special client support, and Exim is probably the
2774 only MTA that supported it -- and would never use it because real RSA is
2775 always available. This code has been removed, because it had the bad
2776 effect of slowing Exim down by computing (never used) parameters for the
2777 RSA_EXPORT functionality.
2778
7befa435
PH
2779PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2780 authenticator to fail if there's a tab character in the incoming data
2781 (there should never be unless someone is messing about, as it's supposed
2782 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2783 if the connection is using TLS or if the remote IP is the same as the
2784 local IP, and the "valid-client-cert option" if a client certificate has
2785 been verified.
2786
48da4259 2787PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
2816
2817PH/30 Exim was sometimes attempting to deliver messages that had suffered
2818 address errors (4xx response to RCPT) over the same connection as other
2819 messages routed to the same hosts. Such deliveries are always "forced",
2820 so retry times are not inspected. This resulted in far too many retries
2821 for the affected addresses. The effect occurred only when there were more
2822 hosts than the hosts_max_try setting in the smtp transport when it had
2823 the 4xx errors. Those hosts that it had tried were not added to the list
2824 of hosts for which the message was waiting, so if all were tried, there
2825 was no problem. Two fixes have been applied:
2826
2827 (i) If there are any address or message errors in an SMTP delivery, none
2828 of the hosts (tried or untried) are now added to the list of hosts
2829 for which the message is waiting, so the message should not be a
2830 candidate for sending over the same connection that was used for a
2831 successful delivery of some other message. This seems entirely
2832 reasonable: after all the message is NOT "waiting for some host".
2833 This is so "obvious" that I'm not sure why it wasn't done
2834 previously. Hope I haven't missed anything, but it can't do any
2835 harm, as the worst effect is to miss an optimization.
2836
2837 (ii) If, despite (i), such a delivery is accidentally attempted, the
2838 routing retry time is respected, so at least it doesn't keep
2839 hammering the server.

2854PH/35 The error "getsockname() failed: connection reset by peer" was being
2855 written to the panic log as well as the main log, but it isn't really
2856 panic-worthy as it just means the connection died rather early on. I have
2857 removed the panic log writing for the ECONNRESET error when getsockname()
2858 fails.
2859
48c7f9e2
PH
2860PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2861 runs only) independently of the message's sender address. This meant
2862 that, if the 4xx error was in fact related to the sender, a different
2863 message to the same recipient with a different sender could confuse
4c04137d 2864 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2865 server, but other circumstances could also provoke similar problems.
2866 I have changed the default so that the retry time for these errors is now
2867 based a combination of the sender and recipient addresses. This change
2868 can be overridden by setting address_retry_include_sender=false in the
2869 smtp transport.

3137PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
3138 "Deny" causes Exim to reject the incoming connection with a 554 error.
3139 Unfortunately, if there is a major crisis, such as a disk failure,
3140 tcp-wrappers gives "deny", whereas what one would like would be some
3141 kind of temporary error. A kludge has been added to help with this.
3142 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3143 554 error is used if errno is still zero or contains ENOENT (which occurs
3144 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
3145 451 error is used.

3167PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3168 folder from quota calculations, a direct delivery into this folder messed
3169 up the contents of the maildirsize file. This was because the regex was
3170 used only to exclude .Trash (or whatever) when the size of the mailbox
3171 was calculated. There was no check that a delivery was happening into an
3172 excluded directory. This bug has been fixed by ignoring all quota
3173 processing for deliveries into excluded directories.

3179-----------------
3180
3181PH/01 The code for finding all the local interface addresses on a FreeBSD
3182 system running IPv6 was broken. This may well have applied to all BSD
3183 systems, as well as to others that have similar system calls. The broken
3184 code found IPv4 interfaces correctly, but gave incorrect values for the
3185 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3186 that it would not match correctly against @[] and not recognize the IPv6
3187 addresses as local.

3197 invalid. However, $reply_address has leading white space removed, and all
3198 newlines turned into spaces so that the autoreply transport does not
3199 grumble.

3228 syntactically invalid From: or Reply-to: line, and a filter used this to
3229 generate an autoreply, and therefore failed to obtain an address for the
3230 autoreply, Exim could try to deliver to a non-existent relative file
3231 name, causing unrelated and misleading errors. What now happens is that
3232 it logs this as a hard delivery error, but does not attempt to create a
3233 bounce message.
