17JH/03 Bug 2269: When presented with a received message having a stupidly large
18 number of DKIM-Signature headers, disable DKIM verification to avoid
19 a resource-consumption attack. The limit is set at twenty.

JH
25JH/05 Bug 2273: Cutthrough delivery left a window where the received messsage
26 files in the spool were present and unlocked. A queue-runner could spot
27 them, resulting in a duplicate delivery. Fix that by doing the unlock
0488984d
JH
28 after the unlink. Investigation by Tim Stewart. Take the opportunity to
29 add more error-checking on spoolfile handling while that code is being

32PP/01 Refuse to open a spool data file (*-D) if it's a symlink.
33 No known attacks, no CVE, this is defensive hardening.

JH
35JH/06 Bug 2275: The MIME ACL unlocked the received message files early, and
36 a queue-runner could start a delivery while other operations were ongoing.
37 Cutthrough delivery was a common victim, resulting in duplicate delivery.
38 Found and investigated by Tim Stewart. Fix by using the open message data
39 file handle rather than opening another, and not locally closing it (which
40 releases a lock) for that case, while creating the temporary .eml format
41 file for the MIME ACL. Also applies to "regex" and "spam" ACL conditions.

JH
55JH/11 Bug 2264: Exim now only follows CNAME chains one step by default. We'd
56 like zero, since the resolver should be doing this for us, But we need one
57 as a CNAME but no MX presence gets the CNAME returned; we need to check
58 that doesn't point to an MX to declare it "no MX returned" rather than
59 "error, loop". A new main option is added so the older capability of
60 following some limited number of chain links is maintained.

c39c8870 68GF/01 DEFER rather than ERROR on redis cluster MOVED response.
bb264f6b
JH
69 When redis_servers is set to a list of > 1 element, and the Redis servers
70 in that list are in cluster configuration, convert the REDIS_REPLY_ERROR
71 case of MOVED into a DEFER case instead, thus moving the query onto the
72 next server in the list. For a cluster of N elements, all N servers must
73 be defined in redis_servers.

JH
89JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
90 we assumed that tags in the header were well-formed, and parsed the
91 element content after inspecting only the first char of the tag.
92 Assumptions at that stage could crash the receive process on malformed
93 input.
94
ce93c6d8
JH
95JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
96 While running the DKIM ACL we operate on the Permanent memory pool so that
97 variables created with "set" persist to the DATA ACL. Also (at any time)
98 DNS lookups that fail create cache records using the Permanent pool. But
99 expansions release any allocations made on the current pool - so a dnsdb
100 lookup expansion done in the DKIM ACL releases the memory used for the
101 DNS negative-cache, and bad things result. Solution is to switch to the
102 Main pool for expansions.
103 While we're in that code, add checks on the DNS cache during store_reset,
104 active in the testsuite.
105 Problem spotted, and debugging aided, by Wolfgang Breyha.
106

JH
107JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
108 When none of the hosts presented to a transport match an already-open
109 connection, close it and proceed with the list. Previously we would
110 queue the message. Spotted by Lena with Yahoo, probably involving
111 round-robin DNS.

113JH/07 Bug 2214: Fix SMTP responses resulting from non-accept result of MIME ACL.

JH
131JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
132 SMTP connection. Previously, when one had more receipients than the
133 first, an abortive onward connection was made. Move to full support for
134 multiple onward connections in sequence, handling cutthrough connection
135 for all multi-message initiating connections.
136
f83a760f
JH
137JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by
138 routers. Previously, a multi-recipient message would fail to match the
139 onward-connection opened for the first recipient, and cause its closure.
140
f1fed05b
JH
141JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
142 a timeout on read on a GnuTLS initiating connection, resulting in the
143 initiating connection being dropped. This mattered most when the callout
144 was marked defer_ok. Fix to keep the two timeout-detection methods
145 separate.
146
051d5efa
JH
147JH/15 Relax results from ACL control request to enable cutthrough, in
148 unsupported situations, from error to silently (except under debug)
149 ignoring. This covers use with PRDR, frozen messages, queue-only and
150 fake-reject.

204JH/28 Ensure that variables possibly set during message acceptance are marked

JH
212JH/29 Bug 2250: Fix a longstanding bug in heavily-pipelined SMTP input (such
213 as a multi-recipient message from a mailinglist manager). The coding had
214 an arbitrary cutoff number of characters while checking for more input;
215 enforced by writing a NUL into the buffer. This corrupted long / fast
216 input. The problem was exposed more widely when more pipelineing of SMTP
217 responses was introduced, and one Exim system was feeding another.
218 The symptom is log complaints of SMTP syntax error (NUL chars) on the
219 receiving system, and refused recipients seen by the sending system
220 (propating to people being dropped from mailing lists).
221 Discovered and pinpointed by David Carter.

291 do not close it down and have the child transport start it up again on
292 the passed-on TCP connection. Instead, proxy the child (and any
293 subsequent ones) for TLS via a unix-domain socket channel. Logging is
294 affected: the continued delivery log lines do not have any DNSSEC, TLS

336JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
337 case where the routing stage had gathered several addresses to send to
338 a host before calling the transport for the first, we previously failed
339 to close down TLS in the old transport process before passing the TCP
340 connection to the new process. The new one sent a STARTTLS command
341 which naturally failed, giving a failed delivery and bloating the retry
342 database. Investigation and fix prototype from Wolfgang Breyha.

344JH/12 Fix check on SMTP command input synchronisation. Previously there were

820JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both

823 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 824 and the trailing two digits of the smtp 4xx response.

1419TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1420
1421 When a queue runner is handling a message, Exim first routes the
1422 recipient addresses, during which it prunes them based on the retry
1423 hints database. After that it attempts to deliver the message to
1424 any remaining recipients. It then updates the hints database using
1425 the retry rules.
1426
1427 So if a recipient address works intermittently, it can get repeatedly
1428 deferred at routing time. The retry hints record remains fresh so the
1429 address never reaches the final cutoff time.
1430
1431 This is a fairly common occurrence when a user is bumping up against
1432 their storage quota. Exim had some logic in its local delivery code
1433 to deal with this. However it did not apply to per-recipient defers
1434 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1435
1ddeb334
TF
1436 This change adds a proper retry rule check during routing so that the
1437 final cutoff time is checked against the message's age. We only do
1438 this check if there is an address retry record and there is not a
1439 domain retry record; this implies that previous attempts to handle
1440 the address had the retry_use_local_parts option turned on. We use
1441 this as an approximation for the destination being like a local
1442 delivery, as in LMTP.
67bd1ab3
TF
1443
1444 I suspect this new check makes the old local delivery cutoff check
1445 redundant, but I have not verified this so I left the code in place.

1767TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1768 lock up or crash if it happened to be inside a call to libc when it
1769 got a SIGUSR1 from exiwhat.
1770
1771 The SIGUSR1 handler appends the current process status to the process
1772 log which is later printed by exiwhat. It used to use the general
1773 purpose logging code to do this, but several functions it calls are
1774 not safe for signals.
1775
1776 The new output code in the SIGUSR1 handler is specific to the process
1777 log, and simple enough that it's easy to inspect for signal safety.
1778 Removing some special cases also simplifies the general logging code.
1779 Removing the spurious timestamps from the process log simplifies
1780 exiwhat.
1781

TF
1782TF/04 Improved ratelimit ACL condition.
1783
1784 The /noupdate option has been deprecated in favour of /readonly which
1785 has clearer semantics. The /leaky, /strict, and /readonly update modes
1786 are mutually exclusive. The update mode is no longer included in the
1787 database key; it just determines when the database is updated. (This
4c04137d 1788 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1789
1790 Exim now checks that the per_* options are used with an update mode that
1791 makes sense for the current ACL. For example, when Exim is processing a
1792 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1793 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1794 must specify per_mail/readonly. If you omit the update mode it defaults to
1795 /leaky where that makes sense (as before) or /readonly where required.
1796
1797 The /noupdate option is now undocumented but still supported for
1798 backwards compatibility. It is equivalent to /readonly except that in
1799 ACLs where /readonly is required you may specify /leaky/noupdate or
1800 /strict/noupdate which are treated the same as /readonly.
1801
1802 A useful new feature is the /count= option. This is a generalization
1803 of the per_byte option, so that you can measure the throughput of other
1804 aggregate values. For example, the per_byte option is now equivalent
1805 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1806
1807 The per_rcpt option has been generalized using the /count= mechanism
1808 (though it's more complicated than the per_byte equivalence). When it is
1809 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1810 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1811 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1812 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1813 Note that using per_rcpt with a non-readonly update mode in more than
1814 one ACL will cause the recipients to be double-counted. (The per_mail
1815 and per_byte options don't have this problem.)
1816
1817 The handling of very low rates has changed slightly. If the computed rate
1818 is less than the event's count (usually one) then this event is the first
1819 after a long gap. In this case the rate is set to the same as this event's
1820 count, so that the first message of a spam run is counted properly.
1821
1822 The major new feature is a mechanism for counting the rate of unique
1823 events. The new per_addr option counts the number of different
1824 recipients that someone has sent messages to in the last time period. It
1825 behaves like per_rcpt if all the recipient addresses are different, but
1826 duplicate recipient addresses do not increase the measured rate. Like
1827 the /count= option this is a general mechanism, so the per_addr option
1828 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1829 example, measure the rate that a client uses different sender addresses
1830 with the options per_mail/unique=$sender_address. There are further
1831 details in the main documentation.

2382 were called 'true' and it seems that C99 defines that as a reserved

2384 not include C99-style headers which use bools without triggering

2401-----------------
2402
2403PH/01 Another patch from the Sieve maintainer.
2404
6a3bceb1
PH
2405PH/02 When an IPv6 address is converted to a string for single-key lookup
2406 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2407 dots are used instead of colons so that keys in lsearch files need not
2408 contain colons. This was done some time before quoting was made available
2409 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2410 (notated using the quote facility) so as to distinguish them from IPv4
2411 keys. This meant that lookups for IP addresses in host lists did not work
2412 for iplsearch lookups.
2413
2414 This has been fixed by arranging for IPv6 addresses to be expressed with
2415 colons if the lookup type is iplsearch. This is not incompatible, because
2416 previously such lookups could never work.
2417
4c04137d 2418 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2419 ordinary lsearch keys. However, making the change in all cases is
2420 incompatible and would probably break a number of configurations.
2421

TK
2422TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
2423 version.
2424
0806a9c5
MH
2425MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2426 conversion specification without a maximum field width, thereby enabling
2427 a rogue spamd server to cause a buffer overflow. While nobody in their
2428 right mind would setup Exim to query an untrusted spamd server, an
2429 attacker that gains access to a server running spamd could potentially
2430 exploit this vulnerability to run arbitrary code as the Exim user.

2434
0f2cbd1b
MH
2435MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2436 a directory entry by the name of the lookup key. Previously, if a
2437 symlink pointed to a non-existing file or a file in a directory that
2438 Exim lacked permissions to read, a lookup for a key matching that
2439 symlink would fail. Now it is enough that a matching directory entry
2440 exists, symlink or not. (Bugzilla 503.)

2480PH/18 If a system quota error occurred while trying to create the file for

2483 only to a quota excession during the actual writing of the file.

2513PH/02 In an ACL statement such as

2515 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
2516
2517 if a client was not listed at all, or was listed with a value other than
2518 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2519 the condition was not true (as it should be), so access was not denied.
2520 The bug was that the ! inversion was incorrectly passed on to the second
2521 item. This has been fixed.

PH
2623PH/29 SMTP synchronization checks are implemented when a command is read -
2624 there is a check that no more input is waiting when there shouldn't be
2625 any. However, for some commands, a delay in an ACL can mean that it is
2626 some time before the response is written. In this time, more input might
2627 arrive, invalidly. So now there are extra checks after an ACL has run for
2628 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2629 pipelining has not been advertised.

PH
2641PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
2642 Exim which did not show up earlier: it was assuming that a call to
2643 SSL_CTX_set_info_callback() might give an error value. In fact, there is
2644 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2645 was a macro that became an assignment, so it seemed to work. This has
2646 changed to a proper function call with a void return, hence the compile
2647 error. Exim's code has been fixed.

2678 started the daemon, but after a SIGHUP it used the Exim user (because it
2679 calls itself on a restart). I have changed the code so that it now always
2680 uses the Exim user.

2684 sender address), and a DATA command is nevertheless sent (as can happen
2685 with PIPELINING or a stupid MUA), the error message that was given to the
2686 RCPT commands is included in the rejection of the DATA command. This is

58eb016e 2702PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
2703 the response to the final '.' that terminates a message, but only in the
2704 case where the client has not sent further data following the '.'
2705 (unfortunately, this is allowed). However, in many cases there won't be
2706 any further data because there won't be any more messages to send. A call
2707 to select() can be used: if it shows that the input is "ready", there is
2708 either input waiting, or the socket has been closed. An attempt to read
2709 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2710 would have sent an OK response which the client would never have see.

2718Exim version 4.66
2719-----------------
2720
2721PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2722 fixed by 4.65/MH/01 (is this a record?) are fixed:
2723
2724 (i) An empty string was always treated as zero by the numeric comparison
2725 operators. This behaviour has been restored.
2726
2727 (ii) It is documented that the numeric comparison operators always treat
2728 their arguments as decimal numbers. This was broken in that numbers
2729 starting with 0 were being interpreted as octal.
2730
2731 While fixing these problems I realized that there was another issue that
2732 hadn't been noticed. Values of message_size_limit (both the global option
2733 and the transport option) were treated as octal if they started with 0.
2734 The documentation was vague. These values are now always treated as
2735 decimal, and I will make that clear in the documentation.

2749PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2750 child addresses, Exim now panics and dies. Previously, because the count
2751 is held in a short int, deliveries were likely to be lost. As such a
2752 large number of recipients for a single message is ridiculous
2753 (performance will be very, very poor), I have chosen to impose a limit
2754 rather than extend the field.

2760TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2761 leftover -K file (the existence of which was triggered by #402).
2762 While we were at it, introduced process PID as part of the -K
2763 filename. This should rule out race conditions when creating
2764 these files.

2766TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2767 processing considerably. Previous code took too long for large mails,
2768 triggering a timeout which in turn triggers #401.
2769
2770TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2771 in the DK code in transports.c. sendfile() is not really portable,

2777 in the field name.

2b1c6e3a
PH
2779PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2780 callout verification, Exim cached a "reject" for the entire domain. This
2781 is correct for most verifications, but it is not correct for a recipient
2782 verification with use_sender or use_postmaster set, because in that case
2783 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2784 case of MAIL FROM:<> rejection from other early rejections (e.g.
2785 rejection of HELO). When verifying a recipient using a non-null MAIL
2786 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2787 Whatever the result of the callout, the value of the domain cache is
2788 left unchanged (for any other kind of callout, getting as far as trying
2789 RCPT means that the domain itself is ok).

2823PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2824 hostname. This is wrong, because it relates to the incoming message (and
2825 probably the interface on which it is arriving) and not to the outgoing
2826 callout (which could be using a different interface). This has been
2827 changed to use the value of the helo_data option from the smtp transport
2828 instead - this is what is used when a message is actually being sent. If
2829 there is no remote transport (possible with a router that sets up host
2830 addresses), $smtp_active_hostname is used.

7befa435 2833 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2834 (a) The code assumed that strncpy() returns a negative number on buffer
2835 overflow, which isn't the case. Replaced with Exim's string_format()
2836 function.
2837 (b) There were several signed/unsigned issues. I just did the minimum
2838 hacking in of casts. There is scope for a larger refactoring.
2839 (c) The code used strcasecmp() which is not a standard C function.
2840 Replaced with Exim's strcmpic() function.
2841 (d) The code set only $1; it now sets $auth1 as well.
2842 (e) A simple test gave the error "authentication client didn't specify
2843 service in request". It would seem that Dovecot has changed its
2844 interface. Fortunately there's a specification; I followed it and
2845 changed what the client sends and it appears to be working now.

2850PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2851 address A is aliased to B and C, where B exists and C does not. Without
2852 -v the output is "A verified" because verification stops after a
2853 successful redirection if more than one address is generated. However,
2854 with -v the child addresses are also verified. Exim was outputting "A
2855 failed to verify" and then showing the successful verification for C,
2856 with its parentage. It now outputs "B failed to verify", showing B's
2857 parentage before showing the successful verification of C.

2860 look up a TXT record in a specific list after matching in a combined
2861 list.
2862
322050c2
PH
2863PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2864 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2865 they consult the DNS. I had assumed they would set it the way they
2866 wanted; and indeed my experiments on Linux seem to show that in some
2867 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2868 To be on the safe side, however, I have now made the interface to
2869 host_find_byname() similar to host_find_bydns(), with an argument
2870 containing the DNS resolver options. The host_find_byname() function now
2871 sets these options at its start, just as host_find_bydns() does. The smtp
2872 transport options dns_qualify_single and dns_search_parents are passed to
2873 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2874 of host_find_byname() use the default settings of RES_DEFNAMES
2875 (qualify_single) but not RES_DNSRCH (search_parents).

2877PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2878 spool_read_header() do less string testing, by means of a preliminary
2879 switch on the second character of optional "-foo" lines. (This is
2880 overdue, caused by the large number of possibilities that now exist.
2881 Originally there were few.) While I was there, I also converted the
2882 str(n)cmp tests so they don't re-test the leading "-" and the first
2883 character, in the hope this might squeeze out yet more improvement.

PH
2885PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2886 flag allowing group syntax was set by the header_syntax check but not
2887 turned off, possible causing trouble later; (2) The flag was not being
2888 set at all for the header_verify test, causing "group"-style headers to
2889 be rejected. I have now set it in this case, and also caused header_
2890 verify to ignore an empty address taken from a group. While doing this, I
2891 came across some other cases where the code for allowing group syntax
2892 while scanning a header line wasn't quite right (mostly, not resetting
2893 the flag correctly in the right place). These bugs could have caused
2894 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2896PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2897 with the "reply" argument non-NULL. The code, however (which originally
2898 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2899 but it didn't always do it. This confused somebody who was copying the
2900 code for some other use. I have removed all the tests.

PH
2902PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2903 feature that was used to support insecure browsers during the U.S. crypto
2904 embargo. It requires special client support, and Exim is probably the
2905 only MTA that supported it -- and would never use it because real RSA is
2906 always available. This code has been removed, because it had the bad
2907 effect of slowing Exim down by computing (never used) parameters for the
2908 RSA_EXPORT functionality.

PH
2910PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2911 authenticator to fail if there's a tab character in the incoming data
2912 (there should never be unless someone is messing about, as it's supposed
2913 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2914 if the connection is using TLS or if the remote IP is the same as the
2915 local IP, and the "valid-client-cert option" if a client certificate has
2916 been verified.

2947
2948PH/30 Exim was sometimes attempting to deliver messages that had suffered
2949 address errors (4xx response to RCPT) over the same connection as other
2950 messages routed to the same hosts. Such deliveries are always "forced",
2951 so retry times are not inspected. This resulted in far too many retries
2952 for the affected addresses. The effect occurred only when there were more
2953 hosts than the hosts_max_try setting in the smtp transport when it had
2954 the 4xx errors. Those hosts that it had tried were not added to the list
2955 of hosts for which the message was waiting, so if all were tried, there
2956 was no problem. Two fixes have been applied:
2957
2958 (i) If there are any address or message errors in an SMTP delivery, none
2959 of the hosts (tried or untried) are now added to the list of hosts
2960 for which the message is waiting, so the message should not be a
2961 candidate for sending over the same connection that was used for a
2962 successful delivery of some other message. This seems entirely
2963 reasonable: after all the message is NOT "waiting for some host".
2964 This is so "obvious" that I'm not sure why it wasn't done
2965 previously. Hope I haven't missed anything, but it can't do any
2966 harm, as the worst effect is to miss an optimization.
2967
2968 (ii) If, despite (i), such a delivery is accidentally attempted, the
2969 routing retry time is respected, so at least it doesn't keep
2970 hammering the server.

2985PH/35 The error "getsockname() failed: connection reset by peer" was being
2986 written to the panic log as well as the main log, but it isn't really

2988 removed the panic log writing for the ECONNRESET error when getsockname()
2989 fails.
2990
48c7f9e2
PH
2991PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2992 runs only) independently of the message's sender address. This meant
2993 that, if the 4xx error was in fact related to the sender, a different
2994 message to the same recipient with a different sender could confuse
4c04137d 2995 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2996 server, but other circumstances could also provoke similar problems.
2997 I have changed the default so that the retry time for these errors is now
2998 based a combination of the sender and recipient addresses. This change
2999 can be overridden by setting address_retry_include_sender=false in the
3000 smtp transport.

3079PH/47 Put in an explicit test for a DNS lookup of an address record where the
3080 "domain" is actually an IP address, and force a failure. This locks out
3081 those revolvers/nameservers that support "A-for-A" lookups, in
3082 contravention of the specifications.

PH
3084PH/48 When a host name was looked up from an IP address, and the subsequent
3085 forward lookup of the name timed out, the host name was left in
3086 $sender_host_name, contrary to the specification.

PH
3088PH/49 Although default lookup types such as lsearch* or cdb*@ have always been
3089 restricted to single-key lookups, Exim was not diagnosing an error if
3090 * or *@ was used with a query-style lookup.

MH
3094MH/01 local_scan ABI version incremented to 1.1. It should have been updated
3095 long ago, but noone interested enough thought of it. Let's just say that
3096 the "1.1" means that there are some new functions that weren't there at
3097 some point in the past.

3114Exim version 4.63
3115-----------------
3116
3117SC/01 Use a glob alias rather than an array ref in eximstats generated
3118 parser. This improves both readability and performance.
3119
3120SC/02 Collect SpamAssassin and rejection statistics in eximstats.
3121 Don't display local sender or destination tables in eximstats unless
3122 there is data to show.
3123 Added average volumes into the eximstats top table text output.
3124
3125SC/03 Collect data on the number of addresses (recipients) as well
3126 as the number of messages in eximstats.

3128TF/01 Correct an error in the documentation for the redirect router. Exim
3129 does (usually) call initgroups() when daemonizing.

PH
3131TF/02 Call initgroups() when dropping privilege in exim.c, so that Exim runs
3132 with consistent privilege compared to when running as a daemon.

3137TF/04 The ratelimit per_rcpt option now works correctly in acl_not_smtp.
3138 Thanks to Dean Brooks <dean@iglou.com> for the patch.

6083aca0
TF
3140TF/05 Make it easier to get SMTP authentication and TLS/SSL support working
3141 by adding some example configuration directives to the default
3142 configuration file. A little bit of work is required to uncomment the
3143 directives and define how usernames and passwords are checked, but
3144 there is now a framework to start from.
3145
765b530f
PH
3146PH/01 Added #define LDAP_DEPRECATED 1 to ldap.c because some of the "old"
3147 functions that Exim currently uses aren't defined in ldap.h for OpenLDAP
3148 without this. I don't know how relevant this is to other LDAP libraries.

3157 directory not expanded when it should be if an expanded home directory
3158 was set for the address (which is overridden by the transport).

3161 libradius.

PH
3163PH/06 Added acl_not_smtp_start, based on Johannes Berg's patch, and set the
3164 bit to forbid control=suppress_local_fixups in the acl_not_smtp ACL,
3165 because it is too late at that time, and has no effect.

PH
3167PH/07 Changed ${quote_pgsql to quote ' as '' instead of \' because of a
3168 security issue with \' (bugzilla #107). I could not use the
3169 PQescapeStringConn() function, because it needs a PGconn value as one of
3170 its arguments.

PH
3172PH/08 When testing addresses using -bt, indicate those final addresses that
3173 are duplicates that would not cause an additional delivery. At least one
3174 person was confused, thinking that -bt output corresponded to deliveries.
3175 (Suppressing duplicates isn't a good idea as you lose the information
3176 about possibly different redirections that led to the duplicates.)

PH
3189PH/13 If write_rejectlog was set false when logging was sent to syslog with
3190 syslog_duplication set false, log lines that would normally be written

3216PH/18 Refactored debugging code in route_finduser() to show more information,
3217 in particular, the error code if getpwnam() issues one.

PH
3219PH/19 Added PQsetClientEncoding(conn, "SQL_ASCII") to the pgsql code module.

3221 any possible encoding problems.

3223PH/20 Perl can change the locale. Exim was resetting it after a ${perl call,
3224 but not after initializing Perl.

PH
3226PH/21 Added a call to PQsetNoticeProcessor() to catch pgsql "notices" and
3227 output them only if debugging. By default they are written stderr,
3228 apparently, which is not desirable.

PH
3238PH/23 Made -oMaa and -oMt work with -bh and -bs to pretend the connection is
3239 authenticated or an ident call has been made. Suppress the default
3240 values for $authenticated_id and $authenticated_sender (but permit -oMai
3241 and -oMas) when testing with -bh.
3242

PH
3243PH/24 Re-jigged the order of the tests in the default configuration so that the
3244 tests for valid domains and recipients precede the DNS black list and CSA
3245 tests, on the grounds that those ones are more expensive.
3246
084efe8d
PH
3247PH/25 Exim was not testing for a space following SMTP commands such as EHLO
3248 that require one. Thus, EHLORHUBARB was interpreted as a valid command.
3249 This bug exists in every version of Exim that I still have, right back to
3250 0.12.

PH
3252PH/26 (n)wildlsearch lookups are documented as being done case-insensitively.
3253 However, an attempt to turn on case-sensitivity in a regex key by
3254 including (?-i) didn't work because the subject string was already
3255 lowercased, and the effects were non-intuitive. It turns out that a
3256 one-line patch can be used to allow (?-i) to work as expected.
