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.

22JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
23 we assumed that tags in the header were well-formed, and parsed the
24 element content after inspecting only the first char of the tag.
25 Assumptions at that stage could crash the receive process on malformed
26 input.

28JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
29 While running the DKIM ACL we operate on the Permanent memory pool so that
30 variables created with "set" persist to the DATA ACL. Also (at any time)
31 DNS lookups that fail create cache records using the Permanent pool. But
32 expansions release any allocations made on the current pool - so a dnsdb
33 lookup expansion done in the DKIM ACL releases the memory used for the
34 DNS negative-cache, and bad things result. Solution is to switch to the
35 Main pool for expansions.
36 While we're in that code, add checks on the DNS cache during store_reset,
37 active in the testsuite.
38 Problem spotted, and debugging aided, by Wolfgang Breyha.

40JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
41 When none of the hosts presented to a transport match an already-open
42 connection, close it and proceed with the list. Previously we would
43 queue the message. Spotted by Lena with Yahoo, probably involving
44 round-robin DNS.

51Exim version 4.90
52-----------------
53
54JH/01 Rework error string handling in TLS interface so that the caller in
55 more cases is responsible for logging. This permits library-sourced
56 string to be attached to addresses during delivery, and collapses
57 pairs of long lines into single ones.
58

PP
59PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
60 during configuration. Wildcards are allowed and expanded.

JH
62JH/02 Rework error string handling in DKIM to pass more info back to callers.
63 This permits better logging.
64
875512a3
JH
65JH/03 Rework the transport continued-connection mechanism: when TLS is active,
66 do not close it down and have the child transport start it up again on
67 the passed-on TCP connection. Instead, proxy the child (and any
68 subsequent ones) for TLS via a unix-domain socket channel. Logging is
69 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 70 Certificate or OCSP information. TLS cipher information is still logged.
875512a3 71

72JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
73 identical IP addresses on different listening ports. Will also affect
74 "exiwhat" output.

77 add noisy ifdef guards to special-case this sillyness.
78 Patch from Bernd Kuhls.

JH
80JH/05 Tighten up the checking in isip4 (et al): dotted-quad components larger
81 than 255 are no longer allowed.
82
7006ee24
JH
83JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
84 Disable the session-cache too, which might reduce our load. Since we
85 currrectly use a new context for every connection, both as server and
86 client, there is no benefit for these.
87 GnuTLS appears to not support tickets server-side by default (we don't
88 call gnutls_session_ticket_enable_server()) but client side is enabled
89 by default on recent versions (3.1.3 +) unless the PFS priority string
90 is used (3.2.4 +).

95JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
96 the check for any unsuccessful recipients did not notice the limit, and
97 erroneously found still-pending ones.

JH
102JH/09 Avoid using a temporary file during transport using dkim. Unless a
103 transport-filter is involved we can buffer the headers in memory for
104 creating the signature, and read the spool data file once for the
105 signature and again for transmission.
106

JH
107JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
108 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 109 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
111JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
112 case where the routing stage had gathered several addresses to send to
113 a host before calling the transport for the first, we previously failed
114 to close down TLS in the old transport process before passing the TCP
115 connection to the new process. The new one sent a STARTTLS command
116 which naturally failed, giving a failed delivery and bloating the retry
117 database. Investigation and fix prototype from Wolfgang Breyha.
118
40525d07
JH
119JH/12 Fix check on SMTP command input synchronisation. Previously there were
120 false-negatives in the check that the sender had not preempted a response
121 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 122 awareness of the SMTP input buffering.
40525d07 123
f33875c3
PP
124PP/04 Add commandline_checks_require_admin option.
125 Exim drops privileges sanely, various checks such as -be aren't a
126 security problem, as long as you trust local users with access to their
127 own account. When invoked by services which pass untrusted data to
128 Exim, this might be an issue. Set this option in main configuration
129 AND make fixes to the calling application, such as using `--` to stop
130 processing options.
131
a5ffa9b4
JH
132JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
133 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
134 responses to those, into a single TLS record each way (this usually means
135 a single packet). As a side issue, smtp_enforce_sync now works on TLS
136 connections.

138PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
139 affects you only if you're dancing at the edge of the param size limits.
140 If you are, and this message makes sense to you, then: raise the
141 configured limit or use OpenSSL 1.1. Nothing we can do for older
142 versions.

372JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
373 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
374 or even an in-clear connection were permitted. Now, if the host lookup
375 was dnssec and dane was requested then the host is only used if the
376 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
377 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
378 if one fails this test.
379 This means that a poorly-configured remote DNS will make it incommunicado;
380 but it protects against a DNS-interception attack on it.

1194TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1195
1196 When a queue runner is handling a message, Exim first routes the
1197 recipient addresses, during which it prunes them based on the retry
1198 hints database. After that it attempts to deliver the message to
1199 any remaining recipients. It then updates the hints database using
1200 the retry rules.
1201
1202 So if a recipient address works intermittently, it can get repeatedly
1203 deferred at routing time. The retry hints record remains fresh so the
1204 address never reaches the final cutoff time.
1205
1206 This is a fairly common occurrence when a user is bumping up against
1207 their storage quota. Exim had some logic in its local delivery code
1208 to deal with this. However it did not apply to per-recipient defers
1209 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1210
1ddeb334
TF
1211 This change adds a proper retry rule check during routing so that the
1212 final cutoff time is checked against the message's age. We only do
1213 this check if there is an address retry record and there is not a
1214 domain retry record; this implies that previous attempts to handle
1215 the address had the retry_use_local_parts option turned on. We use
1216 this as an approximation for the destination being like a local
1217 delivery, as in LMTP.
67bd1ab3
TF
1218
1219 I suspect this new check makes the old local delivery cutoff check
1220 redundant, but I have not verified this so I left the code in place.

1228 When I ran the test suite under the user fanf2, Exim expanded
1229 the header to contain my full name, whereas it should have added
1230 a Resent-Sender: header. It erroneously treats any prefix of the
1231 username as equal to the username.

1260 the body content is received and before the acl_smtp_data ACL.

1542TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1543 lock up or crash if it happened to be inside a call to libc when it
1544 got a SIGUSR1 from exiwhat.
1545
1546 The SIGUSR1 handler appends the current process status to the process
1547 log which is later printed by exiwhat. It used to use the general
1548 purpose logging code to do this, but several functions it calls are
1549 not safe for signals.
1550
1551 The new output code in the SIGUSR1 handler is specific to the process
1552 log, and simple enough that it's easy to inspect for signal safety.
1553 Removing some special cases also simplifies the general logging code.
1554 Removing the spurious timestamps from the process log simplifies

1557TF/04 Improved ratelimit ACL condition.
1558
1559 The /noupdate option has been deprecated in favour of /readonly which
1560 has clearer semantics. The /leaky, /strict, and /readonly update modes
1561 are mutually exclusive. The update mode is no longer included in the
1562 database key; it just determines when the database is updated. (This
4c04137d 1563 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1564
1565 Exim now checks that the per_* options are used with an update mode that
1566 makes sense for the current ACL. For example, when Exim is processing a
1567 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1568 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1569 must specify per_mail/readonly. If you omit the update mode it defaults to
1570 /leaky where that makes sense (as before) or /readonly where required.
1571
1572 The /noupdate option is now undocumented but still supported for
1573 backwards compatibility. It is equivalent to /readonly except that in
1574 ACLs where /readonly is required you may specify /leaky/noupdate or
1575 /strict/noupdate which are treated the same as /readonly.
1576
1577 A useful new feature is the /count= option. This is a generalization
1578 of the per_byte option, so that you can measure the throughput of other
1579 aggregate values. For example, the per_byte option is now equivalent
1580 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1581
1582 The per_rcpt option has been generalized using the /count= mechanism
1583 (though it's more complicated than the per_byte equivalence). When it is
1584 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1585 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1586 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1587 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1588 Note that using per_rcpt with a non-readonly update mode in more than
1589 one ACL will cause the recipients to be double-counted. (The per_mail
1590 and per_byte options don't have this problem.)
1591
1592 The handling of very low rates has changed slightly. If the computed rate
1593 is less than the event's count (usually one) then this event is the first
1594 after a long gap. In this case the rate is set to the same as this event's
1595 count, so that the first message of a spam run is counted properly.
1596
1597 The major new feature is a mechanism for counting the rate of unique
1598 events. The new per_addr option counts the number of different
1599 recipients that someone has sent messages to in the last time period. It
1600 behaves like per_rcpt if all the recipient addresses are different, but
1601 duplicate recipient addresses do not increase the measured rate. Like
1602 the /count= option this is a general mechanism, so the per_addr option
1603 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1604 example, measure the rate that a client uses different sender addresses
1605 with the options per_mail/unique=$sender_address. There are further
1606 details in the main documentation.

2157 were called 'true' and it seems that C99 defines that as a reserved

2177
2178PH/01 Another patch from the Sieve maintainer.
2179
6a3bceb1
PH
2180PH/02 When an IPv6 address is converted to a string for single-key lookup
2181 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2182 dots are used instead of colons so that keys in lsearch files need not
2183 contain colons. This was done some time before quoting was made available
2184 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2185 (notated using the quote facility) so as to distinguish them from IPv4
2186 keys. This meant that lookups for IP addresses in host lists did not work
2187 for iplsearch lookups.
2188
2189 This has been fixed by arranging for IPv6 addresses to be expressed with
2190 colons if the lookup type is iplsearch. This is not incompatible, because
2191 previously such lookups could never work.
2192
4c04137d 2193 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2194 ordinary lsearch keys. However, making the change in all cases is
2195 incompatible and would probably break a number of configurations.

MH
2200MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2201 conversion specification without a maximum field width, thereby enabling
2202 a rogue spamd server to cause a buffer overflow. While nobody in their
2203 right mind would setup Exim to query an untrusted spamd server, an
2204 attacker that gains access to a server running spamd could potentially
2205 exploit this vulnerability to run arbitrary code as the Exim user.

MH
2210MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2211 a directory entry by the name of the lookup key. Previously, if a
2212 symlink pointed to a non-existing file or a file in a directory that
2213 Exim lacked permissions to read, a lookup for a key matching that
2214 symlink would fail. Now it is enough that a matching directory entry
2215 exists, symlink or not. (Bugzilla 503.)

2398PH/29 SMTP synchronization checks are implemented when a command is read -
2399 there is a check that no more input is waiting when there shouldn't be
2400 any. However, for some commands, a delay in an ACL can mean that it is
2401 some time before the response is written. In this time, more input might
2402 arrive, invalidly. So now there are extra checks after an ACL has run for
2403 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2404 pipelining has not been advertised.

PH
2478 the response to the final '.' that terminates a message, but only in the
2479 case where the client has not sent further data following the '.'
2480 (unfortunately, this is allowed). However, in many cases there won't be
2481 any further data because there won't be any more messages to send. A call
2482 to select() can be used: if it shows that the input is "ready", there is
2483 either input waiting, or the socket has been closed. An attempt to read
2484 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2485 would have sent an OK response which the client would never have see.

2496PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2497 fixed by 4.65/MH/01 (is this a record?) are fixed:
2498
2499 (i) An empty string was always treated as zero by the numeric comparison
2500 operators. This behaviour has been restored.
2501
2502 (ii) It is documented that the numeric comparison operators always treat
2503 their arguments as decimal numbers. This was broken in that numbers
2504 starting with 0 were being interpreted as octal.
2505
2506 While fixing these problems I realized that there was another issue that
2507 hadn't been noticed. Values of message_size_limit (both the global option
2508 and the transport option) were treated as octal if they started with 0.
2509 The documentation was vague. These values are now always treated as
2510 decimal, and I will make that clear in the documentation.

2526 is held in a short int, deliveries were likely to be lost. As such a
2527 large number of recipients for a single message is ridiculous
2528 (performance will be very, very poor), I have chosen to impose a limit
2529 rather than extend the field.

PH
2554PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2555 callout verification, Exim cached a "reject" for the entire domain. This
2556 is correct for most verifications, but it is not correct for a recipient
2557 verification with use_sender or use_postmaster set, because in that case
2558 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2559 case of MAIL FROM:<> rejection from other early rejections (e.g.
2560 rejection of HELO). When verifying a recipient using a non-null MAIL
2561 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2562 Whatever the result of the callout, the value of the domain cache is
2563 left unchanged (for any other kind of callout, getting as far as trying
2564 RCPT means that the domain itself is ok).

2598PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2600 probably the interface on which it is arriving) and not to the outgoing
2601 callout (which could be using a different interface). This has been
2602 changed to use the value of the helo_data option from the smtp transport
2603 instead - this is what is used when a message is actually being sent. If
2604 there is no remote transport (possible with a router that sets up host
2605 addresses), $smtp_active_hostname is used.

7befa435 2608 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2609 (a) The code assumed that strncpy() returns a negative number on buffer
2610 overflow, which isn't the case. Replaced with Exim's string_format()
2611 function.
2612 (b) There were several signed/unsigned issues. I just did the minimum
2613 hacking in of casts. There is scope for a larger refactoring.
2614 (c) The code used strcasecmp() which is not a standard C function.
2615 Replaced with Exim's strcmpic() function.
2616 (d) The code set only $1; it now sets $auth1 as well.
2617 (e) A simple test gave the error "authentication client didn't specify
2618 service in request". It would seem that Dovecot has changed its
2619 interface. Fortunately there's a specification; I followed it and
2620 changed what the client sends and it appears to be working now.

2626 address A is aliased to B and C, where B exists and C does not. Without
2627 -v the output is "A verified" because verification stops after a
2628 successful redirection if more than one address is generated. However,
2629 with -v the child addresses are also verified. Exim was outputting "A
2630 failed to verify" and then showing the successful verification for C,
2631 with its parentage. It now outputs "B failed to verify", showing B's
2632 parentage before showing the successful verification of C.

2637
322050c2
PH
2638PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2639 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2640 they consult the DNS. I had assumed they would set it the way they
2641 wanted; and indeed my experiments on Linux seem to show that in some
2642 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2643 To be on the safe side, however, I have now made the interface to
2644 host_find_byname() similar to host_find_bydns(), with an argument
2645 containing the DNS resolver options. The host_find_byname() function now
2646 sets these options at its start, just as host_find_bydns() does. The smtp
2647 transport options dns_qualify_single and dns_search_parents are passed to
2648 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2649 of host_find_byname() use the default settings of RES_DEFNAMES
2650 (qualify_single) but not RES_DNSRCH (search_parents).

2653 spool_read_header() do less string testing, by means of a preliminary
2654 switch on the second character of optional "-foo" lines. (This is
2655 overdue, caused by the large number of possibilities that now exist.
2656 Originally there were few.) While I was there, I also converted the
2657 str(n)cmp tests so they don't re-test the leading "-" and the first
2658 character, in the hope this might squeeze out yet more improvement.

2660PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2661 flag allowing group syntax was set by the header_syntax check but not
2662 turned off, possible causing trouble later; (2) The flag was not being
2663 set at all for the header_verify test, causing "group"-style headers to
2664 be rejected. I have now set it in this case, and also caused header_
2665 verify to ignore an empty address taken from a group. While doing this, I
2666 came across some other cases where the code for allowing group syntax
2667 while scanning a header line wasn't quite right (mostly, not resetting
2668 the flag correctly in the right place). These bugs could have caused
2669 trouble for malformed header lines. I hope it is now all correct.

PH
2671PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2674 but it didn't always do it. This confused somebody who was copying the
2675 code for some other use. I have removed all the tests.

PH
2677PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a

2679 embargo. It requires special client support, and Exim is probably the
2680 only MTA that supported it -- and would never use it because real RSA is
2681 always available. This code has been removed, because it had the bad
2682 effect of slowing Exim down by computing (never used) parameters for the
2683 RSA_EXPORT functionality.

2688 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2689 if the connection is using TLS or if the remote IP is the same as the
2690 local IP, and the "valid-client-cert option" if a client certificate has

2722
2723PH/30 Exim was sometimes attempting to deliver messages that had suffered
2724 address errors (4xx response to RCPT) over the same connection as other
2725 messages routed to the same hosts. Such deliveries are always "forced",
2726 so retry times are not inspected. This resulted in far too many retries
2727 for the affected addresses. The effect occurred only when there were more
2728 hosts than the hosts_max_try setting in the smtp transport when it had
2729 the 4xx errors. Those hosts that it had tried were not added to the list
2730 of hosts for which the message was waiting, so if all were tried, there
2731 was no problem. Two fixes have been applied:
2732
2733 (i) If there are any address or message errors in an SMTP delivery, none
2734 of the hosts (tried or untried) are now added to the list of hosts
2735 for which the message is waiting, so the message should not be a
2736 candidate for sending over the same connection that was used for a
2737 successful delivery of some other message. This seems entirely
2738 reasonable: after all the message is NOT "waiting for some host".
2739 This is so "obvious" that I'm not sure why it wasn't done
2740 previously. Hope I haven't missed anything, but it can't do any
2741 harm, as the worst effect is to miss an optimization.
2742
2743 (ii) If, despite (i), such a delivery is accidentally attempted, the
2744 routing retry time is respected, so at least it doesn't keep
2745 hammering the server.

2763 removed the panic log writing for the ECONNRESET error when getsockname()
2764 fails.
2765
48c7f9e2
PH
2766PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2767 runs only) independently of the message's sender address. This meant
2768 that, if the 4xx error was in fact related to the sender, a different
2769 message to the same recipient with a different sender could confuse
4c04137d 2770 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2771 server, but other circumstances could also provoke similar problems.
2772 I have changed the default so that the retry time for these errors is now
2773 based a combination of the sender and recipient addresses. This change
2774 can be overridden by setting address_retry_include_sender=false in the
2775 smtp transport.

3048 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3049 554 error is used if errno is still zero or contains ENOENT (which occurs

3084Exim version 4.61
3085-----------------
3086
3087PH/01 The code for finding all the local interface addresses on a FreeBSD
3088 system running IPv6 was broken. This may well have applied to all BSD
3089 systems, as well as to others that have similar system calls. The broken
3090 code found IPv4 interfaces correctly, but gave incorrect values for the
3091 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3092 that it would not match correctly against @[] and not recognize the IPv6
3093 addresses as local.

3095PH/02 The ipliteral router was not recognizing addresses of the form user@
3096 [ipv6:....] because it didn't know about the "ipv6:" prefix.

PH
3100PH/04 Changed $reply_address to use the raw form of the headers instead of the
3101 decoded form, because it is most often used to construct To: headers
3102 lines in autoreplies, and the decoded form may well be syntactically
3103 invalid. However, $reply_address has leading white space removed, and all
3104 newlines turned into spaces so that the autoreply transport does not
3105 grumble.

PH
3110PH/06 Increased the number of ACL variables to 20 of each type, and arranged
3111 for visible compile-time settings that can be used to change these
3112 numbers, for those that want even more. Backwards compatibility with old
3113 spool files has been maintained. However, going back to a previous Exim
3114 release will lost any variables that are in spool files.

3116PH/07 Two small changes when running in the test harness: increase delay when
3117 passing a TCP/IP connection to a new process, in case the original
3118 process has to generate a bounce, and remove special handling of
3119 127.0.0.2 (sic), which is no longer necessary.

PH
3133PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3134 syntactically invalid From: or Reply-to: line, and a filter used this to
3135 generate an autoreply, and therefore failed to obtain an address for the
3136 autoreply, Exim could try to deliver to a non-existent relative file
3137 name, causing unrelated and misleading errors. What now happens is that
3138 it logs this as a hard delivery error, but does not attempt to create a
3139 bounce message.

PH
3148PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
3149 compiled. In many other places in Exim, IPv6 addresses are always
3150 recognized, so I have changed this. It also means that IPv4 domain
3151 literals of the form [IPV4:n.n.n.n] are now always recognized.

PH
3153PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3154 used if the router is not running as root, for example, when verifying at
3155 ACL time, or when using -bh. The debugging output from this situation was
3156 non-existent - all you got was a failure to exec. I have made two
3157 changes:
3158
3159 (a) Failures to set uid/gid, the current directory, or a process leader
3160 in a subprocess such as that created by queryprogram now generate
4c04137d 3161 suitable debugging output when -d is set.
59e82a2a
PH
3162
3163 (b) The queryprogram router detects when it is not running as root,
3164 outputs suitable debugging information if -d is set, and then runs
3165 the subprocess without attempting to change uid/gid.

PH
3170PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3171 additional section of a DNS packet that returns MX or SRV records.
3172 Instead, it always explicitly searches for A/AAAA records. This avoids
3173 major problems that occur when a DNS server includes only records of one
3174 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3175 fixed another bug: if SRV records were looked up and the corresponding
3176 address records were *not* found in the additional section, the port
3177 values from the SRV records were lost.
3178

PH
3179PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
3180 using the correct key (the original address) when searching the retry
3181 rules in order to find which one to use for generating the retry hint.
3182
064a94c9
PH
3183PH/18 If quota_warn_message contains a From: header, Exim now refrains from
3184 adding the default one. Similarly, if it contains a Reply-To: header, the
3185 errors_reply_to option, if set, is not used.
3186
727071f8
PH
3187PH/19 When calculating a retry time, Exim used to measure the "time since
3188 failure" by looking at the "first failed" field in the retry record. Now
3189 it does not use this if it is later than than the arrival time of the
3190 message. Instead it uses the arrival time. This makes for better
3191 behaviour in cases where some deliveries succeed, thus re-setting the
3192 "first failed" field. An example is a quota failure for a huge message
3193 when small messages continue to be delivered. Without this change, the
3194 "time since failure" will always be short, possible causing more frequent
3195 delivery attempts for the huge message than are intended.

3198PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as
3199 $1, $2, $3) because the numerical variables can be reset during some
3200 expansion items (e.g. "match"), thereby losing the authentication data.

3205PH/22 Test the values given for quota, quota_filecount, quota_warn_threshold,
3206 mailbox_size, and mailbox_filecount in the appendfile transport. If a
3207 filecount value is greater than 2G or if a quota value is greater than 2G
3208 on a system where the size of off_t is not greater than 4, a panic error
3209 is given.

3211PH/23 When a malformed item such as 1.2.3/24 appears in a host list, it can
3212 never match. The debug and -bh output now contains an explicit error
3213 message indicating a malformed IPv4 address or mask.
3214
3215PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
3216 1.2.3.4 without a mask. Now it is not recognized as an IP address, and
3217 PH/23 above applies.

3226 the IP address matched host_lookup and the reverse lookup yielded a name
3227 that did not have a forward lookup, an error message of the form "no IP
3228 address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
3229 could be logged. Now it outputs the IP address instead of "NULL".

3231PH/28 An enabling patch from MH: add new function child_open_exim2() which

3234 documented for local_scan(), the new function should be too.

3251 information about the queue run such as the pid. This is always present
3252 in "start" and "stop" lines but was omitted from the "abandon" line.
