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.

JH
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.
69

JH
70JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by
71 routers. Previously, a multi-recipient message would fail to match the
72 onward-connection opened for the first recipient, and cause its closure.
73

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.

80JH/15 Relax results from ACL control request to enable cutthrough, in

111-----------------
112
113JH/01 Rework error string handling in TLS interface so that the caller in
114 more cases is responsible for logging. This permits library-sourced
115 string to be attached to addresses during delivery, and collapses
116 pairs of long lines into single ones.

121JH/02 Rework error string handling in DKIM to pass more info back to callers.
122 This permits better logging.
123
875512a3
JH
124JH/03 Rework the transport continued-connection mechanism: when TLS is active,
125 do not close it down and have the child transport start it up again on
126 the passed-on TCP connection. Instead, proxy the child (and any
127 subsequent ones) for TLS via a unix-domain socket channel. Logging is
128 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 129 Certificate or OCSP information. TLS cipher information is still logged.

141
7006ee24
JH
142JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
143 Disable the session-cache too, which might reduce our load. Since we
144 currrectly use a new context for every connection, both as server and
145 client, there is no benefit for these.
146 GnuTLS appears to not support tickets server-side by default (we don't
147 call gnutls_session_ticket_enable_server()) but client side is enabled
148 by default on recent versions (3.1.3 +) unless the PFS priority string
149 is used (3.2.4 +).

JH
154JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
155 the check for any unsuccessful recipients did not notice the limit, and
156 erroneously found still-pending ones.

158JH/08 Pipeline CHUNKING command and data together, on kernels that support
159 MSG_MORE. Only in-clear (not on TLS connections).

JH
161JH/09 Avoid using a temporary file during transport using dkim. Unless a
162 transport-filter is involved we can buffer the headers in memory for
163 creating the signature, and read the spool data file once for the
164 signature and again for transmission.
165

JH
166JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
167 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 168 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
170JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
171 case where the routing stage had gathered several addresses to send to
172 a host before calling the transport for the first, we previously failed
173 to close down TLS in the old transport process before passing the TCP
174 connection to the new process. The new one sent a STARTTLS command
175 which naturally failed, giving a failed delivery and bloating the retry
176 database. Investigation and fix prototype from Wolfgang Breyha.
177
40525d07
JH
178JH/12 Fix check on SMTP command input synchronisation. Previously there were
179 false-negatives in the check that the sender had not preempted a response
180 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 181 awareness of the SMTP input buffering.
40525d07 182
f33875c3
PP
183PP/04 Add commandline_checks_require_admin option.
184 Exim drops privileges sanely, various checks such as -be aren't a
185 security problem, as long as you trust local users with access to their
186 own account. When invoked by services which pass untrusted data to
187 Exim, this might be an issue. Set this option in main configuration
188 AND make fixes to the calling application, such as using `--` to stop
189 processing options.
190
a5ffa9b4
JH
191JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
192 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
193 responses to those, into a single TLS record each way (this usually means
194 a single packet). As a side issue, smtp_enforce_sync now works on TLS
195 connections.

197PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
198 affects you only if you're dancing at the edge of the param size limits.

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

1253TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1254
1255 When a queue runner is handling a message, Exim first routes the
1256 recipient addresses, during which it prunes them based on the retry
1257 hints database. After that it attempts to deliver the message to
1258 any remaining recipients. It then updates the hints database using
1259 the retry rules.
1260
1261 So if a recipient address works intermittently, it can get repeatedly
1262 deferred at routing time. The retry hints record remains fresh so the
1263 address never reaches the final cutoff time.
1264
1265 This is a fairly common occurrence when a user is bumping up against
1266 their storage quota. Exim had some logic in its local delivery code
1267 to deal with this. However it did not apply to per-recipient defers
1268 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1269
1ddeb334
TF
1270 This change adds a proper retry rule check during routing so that the
1271 final cutoff time is checked against the message's age. We only do
1272 this check if there is an address retry record and there is not a
1273 domain retry record; this implies that previous attempts to handle
1274 the address had the retry_use_local_parts option turned on. We use
1275 this as an approximation for the destination being like a local
1276 delivery, as in LMTP.
67bd1ab3
TF
1277
1278 I suspect this new check makes the old local delivery cutoff check
1279 redundant, but I have not verified this so I left the code in place.

1287 When I ran the test suite under the user fanf2, Exim expanded
1288 the header to contain my full name, whereas it should have added
1289 a Resent-Sender: header. It erroneously treats any prefix of the
1290 username as equal to the username.

TF
1601TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1602 lock up or crash if it happened to be inside a call to libc when it
1603 got a SIGUSR1 from exiwhat.
1604
1605 The SIGUSR1 handler appends the current process status to the process
1606 log which is later printed by exiwhat. It used to use the general
1607 purpose logging code to do this, but several functions it calls are
1608 not safe for signals.
1609
1610 The new output code in the SIGUSR1 handler is specific to the process
1611 log, and simple enough that it's easy to inspect for signal safety.
1612 Removing some special cases also simplifies the general logging code.
1613 Removing the spurious timestamps from the process log simplifies
1614 exiwhat.
1615
c99ce5c9
TF
1616TF/04 Improved ratelimit ACL condition.
1617
1618 The /noupdate option has been deprecated in favour of /readonly which
1619 has clearer semantics. The /leaky, /strict, and /readonly update modes
1620 are mutually exclusive. The update mode is no longer included in the
1621 database key; it just determines when the database is updated. (This
4c04137d 1622 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1623
1624 Exim now checks that the per_* options are used with an update mode that
1625 makes sense for the current ACL. For example, when Exim is processing a
1626 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1627 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1628 must specify per_mail/readonly. If you omit the update mode it defaults to
1629 /leaky where that makes sense (as before) or /readonly where required.
1630
1631 The /noupdate option is now undocumented but still supported for
1632 backwards compatibility. It is equivalent to /readonly except that in
1633 ACLs where /readonly is required you may specify /leaky/noupdate or
1634 /strict/noupdate which are treated the same as /readonly.
1635
1636 A useful new feature is the /count= option. This is a generalization
1637 of the per_byte option, so that you can measure the throughput of other
1638 aggregate values. For example, the per_byte option is now equivalent
1639 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1640
1641 The per_rcpt option has been generalized using the /count= mechanism
1642 (though it's more complicated than the per_byte equivalence). When it is
1643 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1644 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1645 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1646 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1647 Note that using per_rcpt with a non-readonly update mode in more than
1648 one ACL will cause the recipients to be double-counted. (The per_mail
1649 and per_byte options don't have this problem.)
1650
1651 The handling of very low rates has changed slightly. If the computed rate
1652 is less than the event's count (usually one) then this event is the first
1653 after a long gap. In this case the rate is set to the same as this event's
1654 count, so that the first message of a spam run is counted properly.
1655
1656 The major new feature is a mechanism for counting the rate of unique
1657 events. The new per_addr option counts the number of different
1658 recipients that someone has sent messages to in the last time period. It
1659 behaves like per_rcpt if all the recipient addresses are different, but
1660 duplicate recipient addresses do not increase the measured rate. Like
1661 the /count= option this is a general mechanism, so the per_addr option
1662 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1663 example, measure the rate that a client uses different sender addresses
1664 with the options per_mail/unique=$sender_address. There are further
1665 details in the main documentation.

2238
6a3bceb1
PH
2239PH/02 When an IPv6 address is converted to a string for single-key lookup
2240 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2241 dots are used instead of colons so that keys in lsearch files need not
2242 contain colons. This was done some time before quoting was made available
2243 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2244 (notated using the quote facility) so as to distinguish them from IPv4
2245 keys. This meant that lookups for IP addresses in host lists did not work
2246 for iplsearch lookups.
2247
2248 This has been fixed by arranging for IPv6 addresses to be expressed with
2249 colons if the lookup type is iplsearch. This is not incompatible, because
2250 previously such lookups could never work.
2251
4c04137d 2252 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2253 ordinary lsearch keys. However, making the change in all cases is
2254 incompatible and would probably break a number of configurations.

MH
2259MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2260 conversion specification without a maximum field width, thereby enabling
2261 a rogue spamd server to cause a buffer overflow. While nobody in their
2262 right mind would setup Exim to query an untrusted spamd server, an
2263 attacker that gains access to a server running spamd could potentially
2264 exploit this vulnerability to run arbitrary code as the Exim user.

MH
2269MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2270 a directory entry by the name of the lookup key. Previously, if a
2271 symlink pointed to a non-existing file or a file in a directory that
2272 Exim lacked permissions to read, a lookup for a key matching that
2273 symlink would fail. Now it is enough that a matching directory entry
2274 exists, symlink or not. (Bugzilla 503.)

2457PH/29 SMTP synchronization checks are implemented when a command is read -
2458 there is a check that no more input is waiting when there shouldn't be

2460 some time before the response is written. In this time, more input might
2461 arrive, invalidly. So now there are extra checks after an ACL has run for
2462 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2463 pipelining has not been advertised.

PH
2537 the response to the final '.' that terminates a message, but only in the
2538 case where the client has not sent further data following the '.'
2539 (unfortunately, this is allowed). However, in many cases there won't be
2540 any further data because there won't be any more messages to send. A call
2541 to select() can be used: if it shows that the input is "ready", there is
2542 either input waiting, or the socket has been closed. An attempt to read
2543 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2544 would have sent an OK response which the client would never have see.

2555PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2556 fixed by 4.65/MH/01 (is this a record?) are fixed:
2557
2558 (i) An empty string was always treated as zero by the numeric comparison
2559 operators. This behaviour has been restored.
2560
2561 (ii) It is documented that the numeric comparison operators always treat
2562 their arguments as decimal numbers. This was broken in that numbers
2563 starting with 0 were being interpreted as octal.
2564
2565 While fixing these problems I realized that there was another issue that
2566 hadn't been noticed. Values of message_size_limit (both the global option
2567 and the transport option) were treated as octal if they started with 0.
2568 The documentation was vague. These values are now always treated as
2569 decimal, and I will make that clear in the documentation.

2586 large number of recipients for a single message is ridiculous

2b1c6e3a
PH
2613PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2614 callout verification, Exim cached a "reject" for the entire domain. This
2615 is correct for most verifications, but it is not correct for a recipient
2616 verification with use_sender or use_postmaster set, because in that case
2617 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2618 case of MAIL FROM:<> rejection from other early rejections (e.g.
2619 rejection of HELO). When verifying a recipient using a non-null MAIL
2620 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2621 Whatever the result of the callout, the value of the domain cache is
2622 left unchanged (for any other kind of callout, getting as far as trying
2623 RCPT means that the domain itself is ok).

2659 probably the interface on which it is arriving) and not to the outgoing
2660 callout (which could be using a different interface). This has been
2661 changed to use the value of the helo_data option from the smtp transport
2662 instead - this is what is used when a message is actually being sent. If
2663 there is no remote transport (possible with a router that sets up host
2664 addresses), $smtp_active_hostname is used.

7befa435 2667 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2668 (a) The code assumed that strncpy() returns a negative number on buffer
2669 overflow, which isn't the case. Replaced with Exim's string_format()
2670 function.
2671 (b) There were several signed/unsigned issues. I just did the minimum
2672 hacking in of casts. There is scope for a larger refactoring.
2673 (c) The code used strcasecmp() which is not a standard C function.
2674 Replaced with Exim's strcmpic() function.
2675 (d) The code set only $1; it now sets $auth1 as well.
2676 (e) A simple test gave the error "authentication client didn't specify
2677 service in request". It would seem that Dovecot has changed its
2678 interface. Fortunately there's a specification; I followed it and
2679 changed what the client sends and it appears to be working now.

2687 successful redirection if more than one address is generated. However,
2688 with -v the child addresses are also verified. Exim was outputting "A
2689 failed to verify" and then showing the successful verification for C,

2697PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2698 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2699 they consult the DNS. I had assumed they would set it the way they
2700 wanted; and indeed my experiments on Linux seem to show that in some
2701 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2702 To be on the safe side, however, I have now made the interface to
2703 host_find_byname() similar to host_find_bydns(), with an argument
2704 containing the DNS resolver options. The host_find_byname() function now
2705 sets these options at its start, just as host_find_bydns() does. The smtp
2706 transport options dns_qualify_single and dns_search_parents are passed to
2707 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2708 of host_find_byname() use the default settings of RES_DEFNAMES
2709 (qualify_single) but not RES_DNSRCH (search_parents).

PH
2711PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2712 spool_read_header() do less string testing, by means of a preliminary
2713 switch on the second character of optional "-foo" lines. (This is
2714 overdue, caused by the large number of possibilities that now exist.
2715 Originally there were few.) While I was there, I also converted the
2716 str(n)cmp tests so they don't re-test the leading "-" and the first
2717 character, in the hope this might squeeze out yet more improvement.

2719PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2720 flag allowing group syntax was set by the header_syntax check but not
2721 turned off, possible causing trouble later; (2) The flag was not being
2722 set at all for the header_verify test, causing "group"-style headers to
2723 be rejected. I have now set it in this case, and also caused header_
2724 verify to ignore an empty address taken from a group. While doing this, I
2725 came across some other cases where the code for allowing group syntax
2726 while scanning a header line wasn't quite right (mostly, not resetting
2727 the flag correctly in the right place). These bugs could have caused
2728 trouble for malformed header lines. I hope it is now all correct.

2730PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2731 with the "reply" argument non-NULL. The code, however (which originally
2732 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2733 but it didn't always do it. This confused somebody who was copying the
2734 code for some other use. I have removed all the tests.

PH
2736PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2737 feature that was used to support insecure browsers during the U.S. crypto
2738 embargo. It requires special client support, and Exim is probably the
2739 only MTA that supported it -- and would never use it because real RSA is
2740 always available. This code has been removed, because it had the bad
2741 effect of slowing Exim down by computing (never used) parameters for the
2742 RSA_EXPORT functionality.

PH
2744PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2745 authenticator to fail if there's a tab character in the incoming data

2747 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2748 if the connection is using TLS or if the remote IP is the same as the
2749 local IP, and the "valid-client-cert option" if a client certificate has
2750 been verified.

2781
2782PH/30 Exim was sometimes attempting to deliver messages that had suffered
2783 address errors (4xx response to RCPT) over the same connection as other
2784 messages routed to the same hosts. Such deliveries are always "forced",
2785 so retry times are not inspected. This resulted in far too many retries
2786 for the affected addresses. The effect occurred only when there were more
2787 hosts than the hosts_max_try setting in the smtp transport when it had
2788 the 4xx errors. Those hosts that it had tried were not added to the list
2789 of hosts for which the message was waiting, so if all were tried, there
2790 was no problem. Two fixes have been applied:
2791
2792 (i) If there are any address or message errors in an SMTP delivery, none
2793 of the hosts (tried or untried) are now added to the list of hosts
2794 for which the message is waiting, so the message should not be a
2795 candidate for sending over the same connection that was used for a
2796 successful delivery of some other message. This seems entirely
2797 reasonable: after all the message is NOT "waiting for some host".
2798 This is so "obvious" that I'm not sure why it wasn't done
2799 previously. Hope I haven't missed anything, but it can't do any
2800 harm, as the worst effect is to miss an optimization.
2801
2802 (ii) If, despite (i), such a delivery is accidentally attempted, the
2803 routing retry time is respected, so at least it doesn't keep
2804 hammering the server.

2820 written to the panic log as well as the main log, but it isn't really

2822 removed the panic log writing for the ECONNRESET error when getsockname()
2823 fails.
2824
48c7f9e2
PH
2825PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2826 runs only) independently of the message's sender address. This meant
2827 that, if the 4xx error was in fact related to the sender, a different
2828 message to the same recipient with a different sender could confuse
4c04137d 2829 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2830 server, but other circumstances could also provoke similar problems.
2831 I have changed the default so that the retry time for these errors is now
2832 based a combination of the sender and recipient addresses. This change
2833 can be overridden by setting address_retry_include_sender=false in the
2834 smtp transport.

3082 that require one. Thus, EHLORHUBARB was interpreted as a valid command.
3083 This bug exists in every version of Exim that I still have, right back to
3084 0.12.

3086PH/26 (n)wildlsearch lookups are documented as being done case-insensitively.
3087 However, an attempt to turn on case-sensitivity in a regex key by
3088 including (?-i) didn't work because the subject string was already
3089 lowercased, and the effects were non-intuitive. It turns out that a
3090 one-line patch can be used to allow (?-i) to work as expected.

3102PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
3103 "Deny" causes Exim to reject the incoming connection with a 554 error.
3104 Unfortunately, if there is a major crisis, such as a disk failure,
3105 tcp-wrappers gives "deny", whereas what one would like would be some
3106 kind of temporary error. A kludge has been added to help with this.
3107 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3108 554 error is used if errno is still zero or contains ENOENT (which occurs
3109 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
3110 451 error is used.

3132PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3133 folder from quota calculations, a direct delivery into this folder messed
3134 up the contents of the maildirsize file. This was because the regex was
3135 used only to exclude .Trash (or whatever) when the size of the mailbox
3136 was calculated. There was no check that a delivery was happening into an
3137 excluded directory. This bug has been fixed by ignoring all quota
3138 processing for deliveries into excluded directories.

3143Exim version 4.61
3144-----------------
3145
3146PH/01 The code for finding all the local interface addresses on a FreeBSD
3147 system running IPv6 was broken. This may well have applied to all BSD
3148 systems, as well as to others that have similar system calls. The broken
3149 code found IPv4 interfaces correctly, but gave incorrect values for the
3150 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3151 that it would not match correctly against @[] and not recognize the IPv6
3152 addresses as local.

3159PH/04 Changed $reply_address to use the raw form of the headers instead of the
3160 decoded form, because it is most often used to construct To: headers
3161 lines in autoreplies, and the decoded form may well be syntactically
3162 invalid. However, $reply_address has leading white space removed, and all
3163 newlines turned into spaces so that the autoreply transport does not
3164 grumble.

3172 spool files has been maintained. However, going back to a previous Exim
3173 release will lost any variables that are in spool files.

3192PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3193 syntactically invalid From: or Reply-to: line, and a filter used this to
3194 generate an autoreply, and therefore failed to obtain an address for the
3195 autoreply, Exim could try to deliver to a non-existent relative file
3196 name, causing unrelated and misleading errors. What now happens is that
3197 it logs this as a hard delivery error, but does not attempt to create a
3198 bounce message.

3207PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
3208 compiled. In many other places in Exim, IPv6 addresses are always

3210 literals of the form [IPV4:n.n.n.n] are now always recognized.

3212PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3213 used if the router is not running as root, for example, when verifying at
3214 ACL time, or when using -bh. The debugging output from this situation was
3215 non-existent - all you got was a failure to exec. I have made two
3216 changes:
3217
3218 (a) Failures to set uid/gid, the current directory, or a process leader
3219 in a subprocess such as that created by queryprogram now generate
4c04137d 3220 suitable debugging output when -d is set.
59e82a2a
PH
3221
3222 (b) The queryprogram router detects when it is not running as root,
3223 outputs suitable debugging information if -d is set, and then runs
3224 the subprocess without attempting to change uid/gid.

PH
3229PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3230 additional section of a DNS packet that returns MX or SRV records.
3231 Instead, it always explicitly searches for A/AAAA records. This avoids
3232 major problems that occur when a DNS server includes only records of one
3233 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3234 fixed another bug: if SRV records were looked up and the corresponding
3235 address records were *not* found in the additional section, the port
3236 values from the SRV records were lost.

3238PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
3239 using the correct key (the original address) when searching the retry
3240 rules in order to find which one to use for generating the retry hint.
3241

PH
3242PH/18 If quota_warn_message contains a From: header, Exim now refrains from
3243 adding the default one. Similarly, if it contains a Reply-To: header, the
3244 errors_reply_to option, if set, is not used.
3245
727071f8
PH
3246PH/19 When calculating a retry time, Exim used to measure the "time since
3247 failure" by looking at the "first failed" field in the retry record. Now
3248 it does not use this if it is later than than the arrival time of the
3249 message. Instead it uses the arrival time. This makes for better
3250 behaviour in cases where some deliveries succeed, thus re-setting the
3251 "first failed" field. An example is a quota failure for a huge message
3252 when small messages continue to be delivered. Without this change, the
3253 "time since failure" will always be short, possible causing more frequent
3254 delivery attempts for the huge message than are intended.
