11JH/01 Replace the store_release() internal interface with store_newblock(),
12 which internalises the check required to safely use the old one, plus
13 the allocate and data copy operations duplicated in both (!) of the
14 extant use locations.

19Exim version 4.90
20-----------------
21
22JH/01 Rework error string handling in TLS interface so that the caller in
23 more cases is responsible for logging. This permits library-sourced
24 string to be attached to addresses during delivery, and collapses
25 pairs of long lines into single ones.
26

PP
27PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
28 during configuration. Wildcards are allowed and expanded.

30JH/02 Rework error string handling in DKIM to pass more info back to callers.
31 This permits better logging.
32
875512a3
JH
33JH/03 Rework the transport continued-connection mechanism: when TLS is active,
34 do not close it down and have the child transport start it up again on
35 the passed-on TCP connection. Instead, proxy the child (and any
36 subsequent ones) for TLS via a unix-domain socket channel. Logging is
37 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 38 Certificate or OCSP information. TLS cipher information is still logged.

40JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
41 identical IP addresses on different listening ports. Will also affect
42 "exiwhat" output.

45 add noisy ifdef guards to special-case this sillyness.
46 Patch from Bernd Kuhls.

JH
48JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger
49 than 255 are no longer allowed.
50
7006ee24
JH
51JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
52 Disable the session-cache too, which might reduce our load. Since we
53 currrectly use a new context for every connection, both as server and
54 client, there is no benefit for these.
55 GnuTLS appears to not support tickets server-side by default (we don't
56 call gnutls_session_ticket_enable_server()) but client side is enabled
57 by default on recent versions (3.1.3 +) unless the PFS priority string
58 is used (3.2.4 +).

JH
63JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
64 the check for any unsuccessful recipients did not notice the limit, and
65 erroneously found still-pending ones.
66
4e910c01
JH
67JH/08 Pipeline CHUNKING command and data together, on kernels that support
68 MSG_MORE. Only in-clear (not on TLS connections).
69
42055a33
JH
70JH/09 Avoid using a temporary file during transport using dkim. Unless a
71 transport-filter is involved we can buffer the headers in memory for
72 creating the signature, and read the spool data file once for the
73 signature and again for transmission.
74
eeb35890
JH
75JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
76 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 77 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
79JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
80 case where the routing stage had gathered several addresses to send to
81 a host before calling the transport for the first, we previously failed
82 to close down TLS in the old transport process before passing the TCP
83 connection to the new process. The new one sent a STARTTLS command
84 which naturally failed, giving a failed delivery and bloating the retry
85 database. Investigation and fix prototype from Wolfgang Breyha.
86
40525d07
JH
87JH/12 Fix check on SMTP command input synchronisation. Previously there were
88 false-negatives in the check that the sender had not preempted a response
89 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 90 awareness of the SMTP input buffering.
40525d07 91
f33875c3
PP
92PP/04 Add commandline_checks_require_admin option.
93 Exim drops privileges sanely, various checks such as -be aren't a
94 security problem, as long as you trust local users with access to their
95 own account. When invoked by services which pass untrusted data to
96 Exim, this might be an issue. Set this option in main configuration
97 AND make fixes to the calling application, such as using `--` to stop
98 processing options.
99
a5ffa9b4
JH
100JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
101 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
102 responses to those, into a single TLS record each way (this usually means
103 a single packet). As a side issue, smtp_enforce_sync now works on TLS
104 connections.

PP
106PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
107 affects you only if you're dancing at the edge of the param size limits.
108 If you are, and this message makes sense to you, then: raise the
109 configured limit or use OpenSSL 1.1. Nothing we can do for older
110 versions.

274JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
275 TCP connections (such as for Spamd) unless the daemon successfully set
276 Fast Open mode on its listening sockets. This fixes breakage seen on
277 too-old kernels or those not configured for Fast Open, at the cost of
278 requiring both directions being enabled for TFO, and TFO never being used
279 by non-daemon-related Exim processes.

340JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
341 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
342 or even an in-clear connection were permitted. Now, if the host lookup
343 was dnssec and dane was requested then the host is only used if the
344 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
345 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
346 if one fails this test.
347 This means that a poorly-configured remote DNS will make it incommunicado;
348 but it protects against a DNS-interception attack on it.

1165 recipient addresses, during which it prunes them based on the retry
1166 hints database. After that it attempts to deliver the message to
1167 any remaining recipients. It then updates the hints database using
1168 the retry rules.
1169
1170 So if a recipient address works intermittently, it can get repeatedly
1171 deferred at routing time. The retry hints record remains fresh so the
1172 address never reaches the final cutoff time.
1173
1174 This is a fairly common occurrence when a user is bumping up against
1175 their storage quota. Exim had some logic in its local delivery code
1176 to deal with this. However it did not apply to per-recipient defers
1177 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1178

TF
1179 This change adds a proper retry rule check during routing so that the
1180 final cutoff time is checked against the message's age. We only do
1181 this check if there is an address retry record and there is not a
1182 domain retry record; this implies that previous attempts to handle
1183 the address had the retry_use_local_parts option turned on. We use
1184 this as an approximation for the destination being like a local
1185 delivery, as in LMTP.
67bd1ab3
TF
1186
1187 I suspect this new check makes the old local delivery cutoff check
1188 redundant, but I have not verified this so I left the code in place.

1195
1196 When I ran the test suite under the user fanf2, Exim expanded
1197 the header to contain my full name, whereas it should have added
1198 a Resent-Sender: header. It erroneously treats any prefix of the
1199 username as equal to the username.

1510TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1511 lock up or crash if it happened to be inside a call to libc when it
1512 got a SIGUSR1 from exiwhat.
1513
1514 The SIGUSR1 handler appends the current process status to the process
1515 log which is later printed by exiwhat. It used to use the general
1516 purpose logging code to do this, but several functions it calls are
1517 not safe for signals.
1518
1519 The new output code in the SIGUSR1 handler is specific to the process
1520 log, and simple enough that it's easy to inspect for signal safety.
1521 Removing some special cases also simplifies the general logging code.
1522 Removing the spurious timestamps from the process log simplifies
1523 exiwhat.

TF
1525TF/04 Improved ratelimit ACL condition.
1526
1527 The /noupdate option has been deprecated in favour of /readonly which
1528 has clearer semantics. The /leaky, /strict, and /readonly update modes
1529 are mutually exclusive. The update mode is no longer included in the
1530 database key; it just determines when the database is updated. (This
4c04137d 1531 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1532
1533 Exim now checks that the per_* options are used with an update mode that
1534 makes sense for the current ACL. For example, when Exim is processing a
1535 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1536 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1537 must specify per_mail/readonly. If you omit the update mode it defaults to
1538 /leaky where that makes sense (as before) or /readonly where required.
1539
1540 The /noupdate option is now undocumented but still supported for
1541 backwards compatibility. It is equivalent to /readonly except that in
1542 ACLs where /readonly is required you may specify /leaky/noupdate or
1543 /strict/noupdate which are treated the same as /readonly.
1544
1545 A useful new feature is the /count= option. This is a generalization
1546 of the per_byte option, so that you can measure the throughput of other
1547 aggregate values. For example, the per_byte option is now equivalent
1548 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1549
1550 The per_rcpt option has been generalized using the /count= mechanism
1551 (though it's more complicated than the per_byte equivalence). When it is
1552 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1553 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1554 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1555 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1556 Note that using per_rcpt with a non-readonly update mode in more than
1557 one ACL will cause the recipients to be double-counted. (The per_mail
1558 and per_byte options don't have this problem.)
1559
1560 The handling of very low rates has changed slightly. If the computed rate
1561 is less than the event's count (usually one) then this event is the first
1562 after a long gap. In this case the rate is set to the same as this event's
1563 count, so that the first message of a spam run is counted properly.
1564
1565 The major new feature is a mechanism for counting the rate of unique
1566 events. The new per_addr option counts the number of different
1567 recipients that someone has sent messages to in the last time period. It
1568 behaves like per_rcpt if all the recipient addresses are different, but
1569 duplicate recipient addresses do not increase the measured rate. Like
1570 the /count= option this is a general mechanism, so the per_addr option
1571 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1572 example, measure the rate that a client uses different sender addresses
1573 with the options per_mail/unique=$sender_address. There are further
1574 details in the main documentation.

2123
2124 Note to Michael Haardt: I had to rename some vars in sieve.c. They
2125 were called 'true' and it seems that C99 defines that as a reserved
2126 keyword to be used with 'bool' variable types. That means you could
2127 not include C99-style headers which use bools without triggering
2128 build errors in sieve.c.

2144-----------------
2145
2146PH/01 Another patch from the Sieve maintainer.
2147
6a3bceb1
PH
2148PH/02 When an IPv6 address is converted to a string for single-key lookup
2149 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2150 dots are used instead of colons so that keys in lsearch files need not
2151 contain colons. This was done some time before quoting was made available
2152 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2153 (notated using the quote facility) so as to distinguish them from IPv4
2154 keys. This meant that lookups for IP addresses in host lists did not work
2155 for iplsearch lookups.
2156
2157 This has been fixed by arranging for IPv6 addresses to be expressed with
2158 colons if the lookup type is iplsearch. This is not incompatible, because
2159 previously such lookups could never work.
2160
4c04137d 2161 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2162 ordinary lsearch keys. However, making the change in all cases is
2163 incompatible and would probably break a number of configurations.
2164

MH
2168MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2169 conversion specification without a maximum field width, thereby enabling
2170 a rogue spamd server to cause a buffer overflow. While nobody in their
2171 right mind would setup Exim to query an untrusted spamd server, an
2172 attacker that gains access to a server running spamd could potentially
2173 exploit this vulnerability to run arbitrary code as the Exim user.

2177
0f2cbd1b
MH
2178MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2179 a directory entry by the name of the lookup key. Previously, if a
2180 symlink pointed to a non-existing file or a file in a directory that
2181 Exim lacked permissions to read, a lookup for a key matching that
2182 symlink would fail. Now it is enough that a matching directory entry
2183 exists, symlink or not. (Bugzilla 503.)

2256PH/02 In an ACL statement such as

2258 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
2259
2260 if a client was not listed at all, or was listed with a value other than
2261 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2262 the condition was not true (as it should be), so access was not denied.
2263 The bug was that the ! inversion was incorrectly passed on to the second
2264 item. This has been fixed.

2366PH/29 SMTP synchronization checks are implemented when a command is read -
2367 there is a check that no more input is waiting when there shouldn't be
2368 any. However, for some commands, a delay in an ACL can mean that it is
2369 some time before the response is written. In this time, more input might
2370 arrive, invalidly. So now there are extra checks after an ACL has run for
2371 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2372 pipelining has not been advertised.

2387 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2388 was a macro that became an assignment, so it seemed to work. This has

2421 started the daemon, but after a SIGHUP it used the Exim user (because it

2428 with PIPELINING or a stupid MUA), the error message that was given to the

PH
2446 the response to the final '.' that terminates a message, but only in the
2447 case where the client has not sent further data following the '.'
2448 (unfortunately, this is allowed). However, in many cases there won't be
2449 any further data because there won't be any more messages to send. A call
2450 to select() can be used: if it shows that the input is "ready", there is
2451 either input waiting, or the socket has been closed. An attempt to read
2452 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2453 would have sent an OK response which the client would never have see.

2461Exim version 4.66
2462-----------------
2463
2464PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2465 fixed by 4.65/MH/01 (is this a record?) are fixed:
2466
2467 (i) An empty string was always treated as zero by the numeric comparison
2468 operators. This behaviour has been restored.
2469
2470 (ii) It is documented that the numeric comparison operators always treat
2471 their arguments as decimal numbers. This was broken in that numbers
2472 starting with 0 were being interpreted as octal.
2473
2474 While fixing these problems I realized that there was another issue that
2475 hadn't been noticed. Values of message_size_limit (both the global option
2476 and the transport option) were treated as octal if they started with 0.
2477 The documentation was vague. These values are now always treated as
2478 decimal, and I will make that clear in the documentation.

2492PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2493 child addresses, Exim now panics and dies. Previously, because the count
2494 is held in a short int, deliveries were likely to be lost. As such a
2495 large number of recipients for a single message is ridiculous
2496 (performance will be very, very poor), I have chosen to impose a limit
2497 rather than extend the field.

2503TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2504 leftover -K file (the existence of which was triggered by #402).

2512
2513TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
2522PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2523 callout verification, Exim cached a "reject" for the entire domain. This
2524 is correct for most verifications, but it is not correct for a recipient
2525 verification with use_sender or use_postmaster set, because in that case
2526 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2527 case of MAIL FROM:<> rejection from other early rejections (e.g.
2528 rejection of HELO). When verifying a recipient using a non-null MAIL
2529 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2530 Whatever the result of the callout, the value of the domain cache is
2531 left unchanged (for any other kind of callout, getting as far as trying
2532 RCPT means that the domain itself is ok).

2566PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2568 probably the interface on which it is arriving) and not to the outgoing
2569 callout (which could be using a different interface). This has been
2570 changed to use the value of the helo_data option from the smtp transport
2571 instead - this is what is used when a message is actually being sent. If
2572 there is no remote transport (possible with a router that sets up host
2573 addresses), $smtp_active_hostname is used.

7befa435 2576 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2577 (a) The code assumed that strncpy() returns a negative number on buffer
2578 overflow, which isn't the case. Replaced with Exim's string_format()
2579 function.
2580 (b) There were several signed/unsigned issues. I just did the minimum
2581 hacking in of casts. There is scope for a larger refactoring.
2582 (c) The code used strcasecmp() which is not a standard C function.
2583 Replaced with Exim's strcmpic() function.
2584 (d) The code set only $1; it now sets $auth1 as well.
2585 (e) A simple test gave the error "authentication client didn't specify
2586 service in request". It would seem that Dovecot has changed its
2587 interface. Fortunately there's a specification; I followed it and
2588 changed what the client sends and it appears to be working now.

2593PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2594 address A is aliased to B and C, where B exists and C does not. Without
2595 -v the output is "A verified" because verification stops after a
2596 successful redirection if more than one address is generated. However,
2597 with -v the child addresses are also verified. Exim was outputting "A
2598 failed to verify" and then showing the successful verification for C,
2599 with its parentage. It now outputs "B failed to verify", showing B's
2600 parentage before showing the successful verification of C.

2603 look up a TXT record in a specific list after matching in a combined

2605
322050c2
PH
2606PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2607 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2608 they consult the DNS. I had assumed they would set it the way they
2609 wanted; and indeed my experiments on Linux seem to show that in some
2610 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2611 To be on the safe side, however, I have now made the interface to
2612 host_find_byname() similar to host_find_bydns(), with an argument
2613 containing the DNS resolver options. The host_find_byname() function now
2614 sets these options at its start, just as host_find_bydns() does. The smtp
2615 transport options dns_qualify_single and dns_search_parents are passed to
2616 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2617 of host_find_byname() use the default settings of RES_DEFNAMES
2618 (qualify_single) but not RES_DNSRCH (search_parents).

2620PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2621 spool_read_header() do less string testing, by means of a preliminary
2622 switch on the second character of optional "-foo" lines. (This is
2623 overdue, caused by the large number of possibilities that now exist.
2624 Originally there were few.) While I was there, I also converted the
2625 str(n)cmp tests so they don't re-test the leading "-" and the first
2626 character, in the hope this might squeeze out yet more improvement.

PH
2628PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2629 flag allowing group syntax was set by the header_syntax check but not
2630 turned off, possible causing trouble later; (2) The flag was not being
2631 set at all for the header_verify test, causing "group"-style headers to
2632 be rejected. I have now set it in this case, and also caused header_
2633 verify to ignore an empty address taken from a group. While doing this, I
2634 came across some other cases where the code for allowing group syntax
2635 while scanning a header line wasn't quite right (mostly, not resetting
2636 the flag correctly in the right place). These bugs could have caused
2637 trouble for malformed header lines. I hope it is now all correct.

PH
2639PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2640 with the "reply" argument non-NULL. The code, however (which originally
2641 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2642 but it didn't always do it. This confused somebody who was copying the
2643 code for some other use. I have removed all the tests.

PH
2645PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2646 feature that was used to support insecure browsers during the U.S. crypto
2647 embargo. It requires special client support, and Exim is probably the
2648 only MTA that supported it -- and would never use it because real RSA is
2649 always available. This code has been removed, because it had the bad
2650 effect of slowing Exim down by computing (never used) parameters for the
2651 RSA_EXPORT functionality.

2656 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2657 if the connection is using TLS or if the remote IP is the same as the
2658 local IP, and the "valid-client-cert option" if a client certificate has
2659 been verified.

2690
2691PH/30 Exim was sometimes attempting to deliver messages that had suffered
2692 address errors (4xx response to RCPT) over the same connection as other
2693 messages routed to the same hosts. Such deliveries are always "forced",
2694 so retry times are not inspected. This resulted in far too many retries
2695 for the affected addresses. The effect occurred only when there were more
2696 hosts than the hosts_max_try setting in the smtp transport when it had
2697 the 4xx errors. Those hosts that it had tried were not added to the list
2698 of hosts for which the message was waiting, so if all were tried, there
2699 was no problem. Two fixes have been applied:
2700
2701 (i) If there are any address or message errors in an SMTP delivery, none
2702 of the hosts (tried or untried) are now added to the list of hosts
2703 for which the message is waiting, so the message should not be a
2704 candidate for sending over the same connection that was used for a
2705 successful delivery of some other message. This seems entirely
2706 reasonable: after all the message is NOT "waiting for some host".
2707 This is so "obvious" that I'm not sure why it wasn't done
2708 previously. Hope I haven't missed anything, but it can't do any
2709 harm, as the worst effect is to miss an optimization.
2710
2711 (ii) If, despite (i), such a delivery is accidentally attempted, the
2712 routing retry time is respected, so at least it doesn't keep
2713 hammering the server.

2728PH/35 The error "getsockname() failed: connection reset by peer" was being
2729 written to the panic log as well as the main log, but it isn't really
2730 panic-worthy as it just means the connection died rather early on. I have
2731 removed the panic log writing for the ECONNRESET error when getsockname()
2732 fails.
2733
48c7f9e2
PH
2734PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2735 runs only) independently of the message's sender address. This meant
2736 that, if the 4xx error was in fact related to the sender, a different
2737 message to the same recipient with a different sender could confuse
4c04137d 2738 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2739 server, but other circumstances could also provoke similar problems.
2740 I have changed the default so that the retry time for these errors is now
2741 based a combination of the sender and recipient addresses. This change
2742 can be overridden by setting address_retry_include_sender=false in the
2743 smtp transport.

3014 tcp-wrappers gives "deny", whereas what one would like would be some
3015 kind of temporary error. A kludge has been added to help with this.
3016 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3017 554 error is used if errno is still zero or contains ENOENT (which occurs
3018 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

3079 for visible compile-time settings that can be used to change these
3080 numbers, for those that want even more. Backwards compatibility with old
3081 spool files has been maintained. However, going back to a previous Exim
3082 release will lost any variables that are in spool files.

3087 127.0.0.2 (sic), which is no longer necessary.

3101PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3102 syntactically invalid From: or Reply-to: line, and a filter used this to
3103 generate an autoreply, and therefore failed to obtain an address for the
3104 autoreply, Exim could try to deliver to a non-existent relative file
3105 name, causing unrelated and misleading errors. What now happens is that
3106 it logs this as a hard delivery error, but does not attempt to create a
3107 bounce message.

3119 literals of the form [IPV4:n.n.n.n] are now always recognized.

3121PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3122 used if the router is not running as root, for example, when verifying at
3123 ACL time, or when using -bh. The debugging output from this situation was
3124 non-existent - all you got was a failure to exec. I have made two
3125 changes:
3126
3127 (a) Failures to set uid/gid, the current directory, or a process leader
3128 in a subprocess such as that created by queryprogram now generate
4c04137d 3129 suitable debugging output when -d is set.

PH
3138PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3139 additional section of a DNS packet that returns MX or SRV records.
3140 Instead, it always explicitly searches for A/AAAA records. This avoids
3141 major problems that occur when a DNS server includes only records of one
3142 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3143 fixed another bug: if SRV records were looked up and the corresponding
3144 address records were *not* found in the additional section, the port
3145 values from the SRV records were lost.

3147PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3151PH/18 If quota_warn_message contains a From: header, Exim now refrains from

PH
3155PH/19 When calculating a retry time, Exim used to measure the "time since
3156 failure" by looking at the "first failed" field in the retry record. Now
3157 it does not use this if it is later than than the arrival time of the
3158 message. Instead it uses the arrival time. This makes for better
3159 behaviour in cases where some deliveries succeed, thus re-setting the
3160 "first failed" field. An example is a quota failure for a huge message
3161 when small messages continue to be delivered. Without this change, the
3162 "time since failure" will always be short, possible causing more frequent
3163 delivery attempts for the huge message than are intended.

3182
3183PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address

PH
3260PH/42 The content-scanning code uses fopen() to create files in which to put
3261 message data. Previously it was not paying any attention to the mode of
3262 the files. Exim runs with umask(0) because the rest of the code creates
3263 files with open(), and sets the required mode explicitly. Thus, these
3264 files were ending up world-writeable. This was not a big issue, because,
3265 being within the spool directory, they were not world-accessible. I have
3266 created a function called modefopen, which takes an additional mode
3267 argument. It sets umask(777), creates the file, chmods it to the required
3268 mode, then resets the umask. All the relevant calls to fopen() in the
3269 content scanning code have been changed to use this function.
