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

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.

64JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
65 SMTP connection. Previously, when one had more receipients than the
66 first, an abortive onward connection was made. Move to full support for
67 multiple onward connections in sequence, handling cutthrough connection
68 for all multi-message initiating connections.

JH
70JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by

72 onward-connection opened for the first recipient, and cause its closure.

JH
74JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
75 a timeout on read on a GnuTLS initiating connection, resulting in the
76 initiating connection being dropped. This mattered most when the callout
77 was marked defer_ok. Fix to keep the two timeout-detection methods
78 separate.

103Exim version 4.90
104-----------------
105
106JH/01 Rework error string handling in TLS interface so that the caller in
107 more cases is responsible for logging. This permits library-sourced
108 string to be attached to addresses during delivery, and collapses
109 pairs of long lines into single ones.

115 This permits better logging.
116
875512a3
JH
117JH/03 Rework the transport continued-connection mechanism: when TLS is active,
118 do not close it down and have the child transport start it up again on
119 the passed-on TCP connection. Instead, proxy the child (and any
120 subsequent ones) for TLS via a unix-domain socket channel. Logging is
121 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 122 Certificate or OCSP information. TLS cipher information is still logged.

JH
135JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
136 Disable the session-cache too, which might reduce our load. Since we
137 currrectly use a new context for every connection, both as server and
138 client, there is no benefit for these.
139 GnuTLS appears to not support tickets server-side by default (we don't
140 call gnutls_session_ticket_enable_server()) but client side is enabled
141 by default on recent versions (3.1.3 +) unless the PFS priority string
142 is used (3.2.4 +).

147JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
148 the check for any unsuccessful recipients did not notice the limit, and
149 erroneously found still-pending ones.

154JH/09 Avoid using a temporary file during transport using dkim. Unless a
155 transport-filter is involved we can buffer the headers in memory for
156 creating the signature, and read the spool data file once for the
157 signature and again for transmission.

JH
163JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
164 case where the routing stage had gathered several addresses to send to
165 a host before calling the transport for the first, we previously failed
166 to close down TLS in the old transport process before passing the TCP
167 connection to the new process. The new one sent a STARTTLS command
168 which naturally failed, giving a failed delivery and bloating the retry
169 database. Investigation and fix prototype from Wolfgang Breyha.
170
40525d07
JH
171JH/12 Fix check on SMTP command input synchronisation. Previously there were
172 false-negatives in the check that the sender had not preempted a response
173 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 174 awareness of the SMTP input buffering.
40525d07 175
f33875c3
PP
176PP/04 Add commandline_checks_require_admin option.
177 Exim drops privileges sanely, various checks such as -be aren't a
178 security problem, as long as you trust local users with access to their
179 own account. When invoked by services which pass untrusted data to
180 Exim, this might be an issue. Set this option in main configuration
181 AND make fixes to the calling application, such as using `--` to stop
182 processing options.
183
a5ffa9b4
JH
184JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
185 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
186 responses to those, into a single TLS record each way (this usually means
187 a single packet). As a side issue, smtp_enforce_sync now works on TLS
188 connections.

JH
424JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
425 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
426 or even an in-clear connection were permitted. Now, if the host lookup
427 was dnssec and dane was requested then the host is only used if the
428 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
429 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
430 if one fails this test.
431 This means that a poorly-configured remote DNS will make it incommunicado;
432 but it protects against a DNS-interception attack on it.

1246TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1247
1248 When a queue runner is handling a message, Exim first routes the
1249 recipient addresses, during which it prunes them based on the retry
1250 hints database. After that it attempts to deliver the message to
1251 any remaining recipients. It then updates the hints database using
1252 the retry rules.
1253
1254 So if a recipient address works intermittently, it can get repeatedly
1255 deferred at routing time. The retry hints record remains fresh so the
1256 address never reaches the final cutoff time.
1257
1258 This is a fairly common occurrence when a user is bumping up against
1259 their storage quota. Exim had some logic in its local delivery code
1260 to deal with this. However it did not apply to per-recipient defers
1261 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1262
1ddeb334
TF
1263 This change adds a proper retry rule check during routing so that the
1264 final cutoff time is checked against the message's age. We only do
1265 this check if there is an address retry record and there is not a
1266 domain retry record; this implies that previous attempts to handle
1267 the address had the retry_use_local_parts option turned on. We use
1268 this as an approximation for the destination being like a local
1269 delivery, as in LMTP.
67bd1ab3
TF
1270
1271 I suspect this new check makes the old local delivery cutoff check
1272 redundant, but I have not verified this so I left the code in place.

1280 When I ran the test suite under the user fanf2, Exim expanded
1281 the header to contain my full name, whereas it should have added
1282 a Resent-Sender: header. It erroneously treats any prefix of the
1283 username as equal to the username.

1307 Server implementation by Todd Lyons, client by JH.
1308 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
1309 config variable "prdr_enable" controls whether the server

1312 the body content is received and before the acl_smtp_data ACL.

1594TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1595 lock up or crash if it happened to be inside a call to libc when it
1596 got a SIGUSR1 from exiwhat.
1597
1598 The SIGUSR1 handler appends the current process status to the process
1599 log which is later printed by exiwhat. It used to use the general
1600 purpose logging code to do this, but several functions it calls are
1601 not safe for signals.
1602
1603 The new output code in the SIGUSR1 handler is specific to the process
1604 log, and simple enough that it's easy to inspect for signal safety.
1605 Removing some special cases also simplifies the general logging code.
1606 Removing the spurious timestamps from the process log simplifies
1607 exiwhat.

TF
1609TF/04 Improved ratelimit ACL condition.
1610
1611 The /noupdate option has been deprecated in favour of /readonly which
1612 has clearer semantics. The /leaky, /strict, and /readonly update modes
1613 are mutually exclusive. The update mode is no longer included in the
1614 database key; it just determines when the database is updated. (This
4c04137d 1615 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1616
1617 Exim now checks that the per_* options are used with an update mode that
1618 makes sense for the current ACL. For example, when Exim is processing a
1619 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1620 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1621 must specify per_mail/readonly. If you omit the update mode it defaults to
1622 /leaky where that makes sense (as before) or /readonly where required.
1623
1624 The /noupdate option is now undocumented but still supported for
1625 backwards compatibility. It is equivalent to /readonly except that in
1626 ACLs where /readonly is required you may specify /leaky/noupdate or
1627 /strict/noupdate which are treated the same as /readonly.
1628
1629 A useful new feature is the /count= option. This is a generalization
1630 of the per_byte option, so that you can measure the throughput of other
1631 aggregate values. For example, the per_byte option is now equivalent
1632 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1633
1634 The per_rcpt option has been generalized using the /count= mechanism
1635 (though it's more complicated than the per_byte equivalence). When it is
1636 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1637 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1638 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1639 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1640 Note that using per_rcpt with a non-readonly update mode in more than
1641 one ACL will cause the recipients to be double-counted. (The per_mail
1642 and per_byte options don't have this problem.)
1643
1644 The handling of very low rates has changed slightly. If the computed rate
1645 is less than the event's count (usually one) then this event is the first
1646 after a long gap. In this case the rate is set to the same as this event's
1647 count, so that the first message of a spam run is counted properly.
1648
1649 The major new feature is a mechanism for counting the rate of unique
1650 events. The new per_addr option counts the number of different
1651 recipients that someone has sent messages to in the last time period. It
1652 behaves like per_rcpt if all the recipient addresses are different, but
1653 duplicate recipient addresses do not increase the measured rate. Like
1654 the /count= option this is a general mechanism, so the per_addr option
1655 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1656 example, measure the rate that a client uses different sender addresses
1657 with the options per_mail/unique=$sender_address. There are further
1658 details in the main documentation.

2230PH/01 Another patch from the Sieve maintainer.
2231
6a3bceb1
PH
2232PH/02 When an IPv6 address is converted to a string for single-key lookup
2233 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2234 dots are used instead of colons so that keys in lsearch files need not
2235 contain colons. This was done some time before quoting was made available
2236 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2237 (notated using the quote facility) so as to distinguish them from IPv4
2238 keys. This meant that lookups for IP addresses in host lists did not work
2239 for iplsearch lookups.
2240
2241 This has been fixed by arranging for IPv6 addresses to be expressed with
2242 colons if the lookup type is iplsearch. This is not incompatible, because
2243 previously such lookups could never work.
2244
4c04137d 2245 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2246 ordinary lsearch keys. However, making the change in all cases is
2247 incompatible and would probably break a number of configurations.

MH
2252MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2253 conversion specification without a maximum field width, thereby enabling
2254 a rogue spamd server to cause a buffer overflow. While nobody in their
2255 right mind would setup Exim to query an untrusted spamd server, an
2256 attacker that gains access to a server running spamd could potentially
2257 exploit this vulnerability to run arbitrary code as the Exim user.

MH
2262MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2263 a directory entry by the name of the lookup key. Previously, if a
2264 symlink pointed to a non-existing file or a file in a directory that
2265 Exim lacked permissions to read, a lookup for a key matching that
2266 symlink would fail. Now it is enough that a matching directory entry
2267 exists, symlink or not. (Bugzilla 503.)

2450PH/29 SMTP synchronization checks are implemented when a command is read -
2451 there is a check that no more input is waiting when there shouldn't be

2453 some time before the response is written. In this time, more input might
2454 arrive, invalidly. So now there are extra checks after an ACL has run for
2455 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2456 pipelining has not been advertised.

PH
2530 the response to the final '.' that terminates a message, but only in the
2531 case where the client has not sent further data following the '.'
2532 (unfortunately, this is allowed). However, in many cases there won't be
2533 any further data because there won't be any more messages to send. A call
2534 to select() can be used: if it shows that the input is "ready", there is
2535 either input waiting, or the socket has been closed. An attempt to read
2536 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2537 would have sent an OK response which the client would never have see.

2548PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2549 fixed by 4.65/MH/01 (is this a record?) are fixed:
2550
2551 (i) An empty string was always treated as zero by the numeric comparison
2552 operators. This behaviour has been restored.
2553
2554 (ii) It is documented that the numeric comparison operators always treat
2555 their arguments as decimal numbers. This was broken in that numbers
2556 starting with 0 were being interpreted as octal.
2557
2558 While fixing these problems I realized that there was another issue that
2559 hadn't been noticed. Values of message_size_limit (both the global option
2560 and the transport option) were treated as octal if they started with 0.
2561 The documentation was vague. These values are now always treated as
2562 decimal, and I will make that clear in the documentation.

2579 large number of recipients for a single message is ridiculous
2580 (performance will be very, very poor), I have chosen to impose a limit
2581 rather than extend the field.

2b1c6e3a
PH
2606PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2607 callout verification, Exim cached a "reject" for the entire domain. This
2608 is correct for most verifications, but it is not correct for a recipient
2609 verification with use_sender or use_postmaster set, because in that case
2610 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2611 case of MAIL FROM:<> rejection from other early rejections (e.g.
2612 rejection of HELO). When verifying a recipient using a non-null MAIL
2613 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2614 Whatever the result of the callout, the value of the domain cache is
2615 left unchanged (for any other kind of callout, getting as far as trying
2616 RCPT means that the domain itself is ok).

2650PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2652 probably the interface on which it is arriving) and not to the outgoing
2653 callout (which could be using a different interface). This has been
2654 changed to use the value of the helo_data option from the smtp transport
2655 instead - this is what is used when a message is actually being sent. If
2656 there is no remote transport (possible with a router that sets up host
2657 addresses), $smtp_active_hostname is used.

7befa435 2660 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2661 (a) The code assumed that strncpy() returns a negative number on buffer
2662 overflow, which isn't the case. Replaced with Exim's string_format()
2663 function.
2664 (b) There were several signed/unsigned issues. I just did the minimum
2665 hacking in of casts. There is scope for a larger refactoring.
2666 (c) The code used strcasecmp() which is not a standard C function.
2667 Replaced with Exim's strcmpic() function.
2668 (d) The code set only $1; it now sets $auth1 as well.
2669 (e) A simple test gave the error "authentication client didn't specify
2670 service in request". It would seem that Dovecot has changed its
2671 interface. Fortunately there's a specification; I followed it and
2672 changed what the client sends and it appears to be working now.

2679 -v the output is "A verified" because verification stops after a
2680 successful redirection if more than one address is generated. However,
2681 with -v the child addresses are also verified. Exim was outputting "A
2682 failed to verify" and then showing the successful verification for C,
2683 with its parentage. It now outputs "B failed to verify", showing B's
2684 parentage before showing the successful verification of C.

PH
2690PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2691 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2692 they consult the DNS. I had assumed they would set it the way they
2693 wanted; and indeed my experiments on Linux seem to show that in some
2694 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2695 To be on the safe side, however, I have now made the interface to
2696 host_find_byname() similar to host_find_bydns(), with an argument
2697 containing the DNS resolver options. The host_find_byname() function now
2698 sets these options at its start, just as host_find_bydns() does. The smtp
2699 transport options dns_qualify_single and dns_search_parents are passed to
2700 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2701 of host_find_byname() use the default settings of RES_DEFNAMES
2702 (qualify_single) but not RES_DNSRCH (search_parents).

2704PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2705 spool_read_header() do less string testing, by means of a preliminary
2706 switch on the second character of optional "-foo" lines. (This is
2707 overdue, caused by the large number of possibilities that now exist.
2708 Originally there were few.) While I was there, I also converted the
2709 str(n)cmp tests so they don't re-test the leading "-" and the first
2710 character, in the hope this might squeeze out yet more improvement.

2712PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2713 flag allowing group syntax was set by the header_syntax check but not
2714 turned off, possible causing trouble later; (2) The flag was not being
2715 set at all for the header_verify test, causing "group"-style headers to
2716 be rejected. I have now set it in this case, and also caused header_
2717 verify to ignore an empty address taken from a group. While doing this, I
2718 came across some other cases where the code for allowing group syntax
2719 while scanning a header line wasn't quite right (mostly, not resetting
2720 the flag correctly in the right place). These bugs could have caused
2721 trouble for malformed header lines. I hope it is now all correct.

2723PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2724 with the "reply" argument non-NULL. The code, however (which originally
2725 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2726 but it didn't always do it. This confused somebody who was copying the
2727 code for some other use. I have removed all the tests.

2729PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2730 feature that was used to support insecure browsers during the U.S. crypto
2731 embargo. It requires special client support, and Exim is probably the
2732 only MTA that supported it -- and would never use it because real RSA is
2733 always available. This code has been removed, because it had the bad
2734 effect of slowing Exim down by computing (never used) parameters for the
2735 RSA_EXPORT functionality.

2737PH/21 On the advice of Timo Sirainen, added a check to the dovecot

2740 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2741 if the connection is using TLS or if the remote IP is the same as the
2742 local IP, and the "valid-client-cert option" if a client certificate has
2743 been verified.

2774
2775PH/30 Exim was sometimes attempting to deliver messages that had suffered
2776 address errors (4xx response to RCPT) over the same connection as other
2777 messages routed to the same hosts. Such deliveries are always "forced",
2778 so retry times are not inspected. This resulted in far too many retries
2779 for the affected addresses. The effect occurred only when there were more
2780 hosts than the hosts_max_try setting in the smtp transport when it had
2781 the 4xx errors. Those hosts that it had tried were not added to the list
2782 of hosts for which the message was waiting, so if all were tried, there
2783 was no problem. Two fixes have been applied:
2784
2785 (i) If there are any address or message errors in an SMTP delivery, none
2786 of the hosts (tried or untried) are now added to the list of hosts
2787 for which the message is waiting, so the message should not be a
2788 candidate for sending over the same connection that was used for a
2789 successful delivery of some other message. This seems entirely
2790 reasonable: after all the message is NOT "waiting for some host".
2791 This is so "obvious" that I'm not sure why it wasn't done
2792 previously. Hope I haven't missed anything, but it can't do any
2793 harm, as the worst effect is to miss an optimization.
2794
2795 (ii) If, despite (i), such a delivery is accidentally attempted, the
2796 routing retry time is respected, so at least it doesn't keep
2797 hammering the server.

2813 written to the panic log as well as the main log, but it isn't really

2815 removed the panic log writing for the ECONNRESET error when getsockname()
2816 fails.
2817
48c7f9e2
PH
2818PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2819 runs only) independently of the message's sender address. This meant
2820 that, if the 4xx error was in fact related to the sender, a different
2821 message to the same recipient with a different sender could confuse
4c04137d 2822 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2823 server, but other circumstances could also provoke similar problems.
2824 I have changed the default so that the retry time for these errors is now
2825 based a combination of the sender and recipient addresses. This change
2826 can be overridden by setting address_retry_include_sender=false in the
2827 smtp transport.

3081 including (?-i) didn't work because the subject string was already
3082 lowercased, and the effects were non-intuitive. It turns out that a
3083 one-line patch can be used to allow (?-i) to work as expected.

3095PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
3096 "Deny" causes Exim to reject the incoming connection with a 554 error.
3097 Unfortunately, if there is a major crisis, such as a disk failure,
3098 tcp-wrappers gives "deny", whereas what one would like would be some
3099 kind of temporary error. A kludge has been added to help with this.
3100 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3101 554 error is used if errno is still zero or contains ENOENT (which occurs
3102 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
3103 451 error is used.

3125PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3126 folder from quota calculations, a direct delivery into this folder messed
3127 up the contents of the maildirsize file. This was because the regex was
3128 used only to exclude .Trash (or whatever) when the size of the mailbox
3129 was calculated. There was no check that a delivery was happening into an
3130 excluded directory. This bug has been fixed by ignoring all quota
3131 processing for deliveries into excluded directories.

3136Exim version 4.61
3137-----------------
3138
3139PH/01 The code for finding all the local interface addresses on a FreeBSD
3140 system running IPv6 was broken. This may well have applied to all BSD
3141 systems, as well as to others that have similar system calls. The broken
3142 code found IPv4 interfaces correctly, but gave incorrect values for the
3143 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3144 that it would not match correctly against @[] and not recognize the IPv6
3145 addresses as local.

3152PH/04 Changed $reply_address to use the raw form of the headers instead of the
3153 decoded form, because it is most often used to construct To: headers
3154 lines in autoreplies, and the decoded form may well be syntactically
3155 invalid. However, $reply_address has leading white space removed, and all
3156 newlines turned into spaces so that the autoreply transport does not
3157 grumble.

3185PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3186 syntactically invalid From: or Reply-to: line, and a filter used this to
3187 generate an autoreply, and therefore failed to obtain an address for the
3188 autoreply, Exim could try to deliver to a non-existent relative file
3189 name, causing unrelated and misleading errors. What now happens is that
3190 it logs this as a hard delivery error, but does not attempt to create a
3191 bounce message.

3203 literals of the form [IPV4:n.n.n.n] are now always recognized.

3205PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3206 used if the router is not running as root, for example, when verifying at
3207 ACL time, or when using -bh. The debugging output from this situation was
3208 non-existent - all you got was a failure to exec. I have made two
3209 changes:
3210
3211 (a) Failures to set uid/gid, the current directory, or a process leader
3212 in a subprocess such as that created by queryprogram now generate
4c04137d 3213 suitable debugging output when -d is set.
59e82a2a
PH
3214
3215 (b) The queryprogram router detects when it is not running as root,

3217 the subprocess without attempting to change uid/gid.

3222PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3223 additional section of a DNS packet that returns MX or SRV records.
3224 Instead, it always explicitly searches for A/AAAA records. This avoids
3225 major problems that occur when a DNS server includes only records of one
3226 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3227 fixed another bug: if SRV records were looked up and the corresponding
3228 address records were *not* found in the additional section, the port
3229 values from the SRV records were lost.

3231PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3235PH/18 If quota_warn_message contains a From: header, Exim now refrains from

3237 errors_reply_to option, if set, is not used.
3238

PH
3239PH/19 When calculating a retry time, Exim used to measure the "time since
3240 failure" by looking at the "first failed" field in the retry record. Now
3241 it does not use this if it is later than than the arrival time of the
3242 message. Instead it uses the arrival time. This makes for better
3243 behaviour in cases where some deliveries succeed, thus re-setting the
3244 "first failed" field. An example is a quota failure for a huge message
3245 when small messages continue to be delivered. Without this change, the
3246 "time since failure" will always be short, possible causing more frequent
3247 delivery attempts for the huge message than are intended.
