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.

JH
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.
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

108-----------------
109
110JH/01 Rework error string handling in TLS interface so that the caller in
111 more cases is responsible for logging. This permits library-sourced
112 string to be attached to addresses during delivery, and collapses
113 pairs of long lines into single ones.

118JH/02 Rework error string handling in DKIM to pass more info back to callers.
119 This permits better logging.
120
875512a3
JH
121JH/03 Rework the transport continued-connection mechanism: when TLS is active,
122 do not close it down and have the child transport start it up again on
123 the passed-on TCP connection. Instead, proxy the child (and any
124 subsequent ones) for TLS via a unix-domain socket channel. Logging is
125 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 126 Certificate or OCSP information. TLS cipher information is still logged.

7006ee24
JH
139JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
140 Disable the session-cache too, which might reduce our load. Since we
141 currrectly use a new context for every connection, both as server and
142 client, there is no benefit for these.
143 GnuTLS appears to not support tickets server-side by default (we don't
144 call gnutls_session_ticket_enable_server()) but client side is enabled
145 by default on recent versions (3.1.3 +) unless the PFS priority string
146 is used (3.2.4 +).

JH
151JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
152 the check for any unsuccessful recipients did not notice the limit, and
153 erroneously found still-pending ones.

156 MSG_MORE. Only in-clear (not on TLS connections).

JH
158JH/09 Avoid using a temporary file during transport using dkim. Unless a
159 transport-filter is involved we can buffer the headers in memory for
160 creating the signature, and read the spool data file once for the
161 signature and again for transmission.

163JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
164 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 165 mode. Now, it's been long enough. Add support for FreeBSD also.

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

194PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This

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

1250TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1251
1252 When a queue runner is handling a message, Exim first routes the
1253 recipient addresses, during which it prunes them based on the retry
1254 hints database. After that it attempts to deliver the message to
1255 any remaining recipients. It then updates the hints database using
1256 the retry rules.
1257
1258 So if a recipient address works intermittently, it can get repeatedly
1259 deferred at routing time. The retry hints record remains fresh so the
1260 address never reaches the final cutoff time.
1261
1262 This is a fairly common occurrence when a user is bumping up against
1263 their storage quota. Exim had some logic in its local delivery code
1264 to deal with this. However it did not apply to per-recipient defers
1265 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1266
1ddeb334
TF
1267 This change adds a proper retry rule check during routing so that the
1268 final cutoff time is checked against the message's age. We only do
1269 this check if there is an address retry record and there is not a
1270 domain retry record; this implies that previous attempts to handle
1271 the address had the retry_use_local_parts option turned on. We use
1272 this as an approximation for the destination being like a local
1273 delivery, as in LMTP.
67bd1ab3
TF
1274
1275 I suspect this new check makes the old local delivery cutoff check
1276 redundant, but I have not verified this so I left the code in place.

1284 When I ran the test suite under the user fanf2, Exim expanded
1285 the header to contain my full name, whereas it should have added
1286 a Resent-Sender: header. It erroneously treats any prefix of the
1287 username as equal to the username.

1598TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1599 lock up or crash if it happened to be inside a call to libc when it
1600 got a SIGUSR1 from exiwhat.
1601
1602 The SIGUSR1 handler appends the current process status to the process
1603 log which is later printed by exiwhat. It used to use the general
1604 purpose logging code to do this, but several functions it calls are
1605 not safe for signals.
1606
1607 The new output code in the SIGUSR1 handler is specific to the process
1608 log, and simple enough that it's easy to inspect for signal safety.
1609 Removing some special cases also simplifies the general logging code.
1610 Removing the spurious timestamps from the process log simplifies
1611 exiwhat.

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

2233
2234PH/01 Another patch from the Sieve maintainer.
2235
6a3bceb1
PH
2236PH/02 When an IPv6 address is converted to a string for single-key lookup
2237 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2238 dots are used instead of colons so that keys in lsearch files need not
2239 contain colons. This was done some time before quoting was made available
2240 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2241 (notated using the quote facility) so as to distinguish them from IPv4
2242 keys. This meant that lookups for IP addresses in host lists did not work
2243 for iplsearch lookups.
2244
2245 This has been fixed by arranging for IPv6 addresses to be expressed with
2246 colons if the lookup type is iplsearch. This is not incompatible, because
2247 previously such lookups could never work.
2248
4c04137d 2249 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2250 ordinary lsearch keys. However, making the change in all cases is
2251 incompatible and would probably break a number of configurations.

MH
2256MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2257 conversion specification without a maximum field width, thereby enabling
2258 a rogue spamd server to cause a buffer overflow. While nobody in their
2259 right mind would setup Exim to query an untrusted spamd server, an
2260 attacker that gains access to a server running spamd could potentially
2261 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
2266MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2267 a directory entry by the name of the lookup key. Previously, if a
2268 symlink pointed to a non-existing file or a file in a directory that
2269 Exim lacked permissions to read, a lookup for a key matching that
2270 symlink would fail. Now it is enough that a matching directory entry
2271 exists, symlink or not. (Bugzilla 503.)

2454PH/29 SMTP synchronization checks are implemented when a command is read -
2455 there is a check that no more input is waiting when there shouldn't be

2457 some time before the response is written. In this time, more input might
2458 arrive, invalidly. So now there are extra checks after an ACL has run for
2459 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2460 pipelining has not been advertised.

PH
2534 the response to the final '.' that terminates a message, but only in the
2535 case where the client has not sent further data following the '.'
2536 (unfortunately, this is allowed). However, in many cases there won't be
2537 any further data because there won't be any more messages to send. A call
2538 to select() can be used: if it shows that the input is "ready", there is
2539 either input waiting, or the socket has been closed. An attempt to read
2540 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2541 would have sent an OK response which the client would never have see.

2552PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2553 fixed by 4.65/MH/01 (is this a record?) are fixed:
2554
2555 (i) An empty string was always treated as zero by the numeric comparison
2556 operators. This behaviour has been restored.
2557
2558 (ii) It is documented that the numeric comparison operators always treat
2559 their arguments as decimal numbers. This was broken in that numbers
2560 starting with 0 were being interpreted as octal.
2561
2562 While fixing these problems I realized that there was another issue that
2563 hadn't been noticed. Values of message_size_limit (both the global option
2564 and the transport option) were treated as octal if they started with 0.
2565 The documentation was vague. These values are now always treated as
2566 decimal, and I will make that clear in the documentation.

2583 large number of recipients for a single message is ridiculous

PH
2610PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2611 callout verification, Exim cached a "reject" for the entire domain. This
2612 is correct for most verifications, but it is not correct for a recipient
2613 verification with use_sender or use_postmaster set, because in that case
2614 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2615 case of MAIL FROM:<> rejection from other early rejections (e.g.
2616 rejection of HELO). When verifying a recipient using a non-null MAIL
2617 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2618 Whatever the result of the callout, the value of the domain cache is
2619 left unchanged (for any other kind of callout, getting as far as trying
2620 RCPT means that the domain itself is ok).

2656 probably the interface on which it is arriving) and not to the outgoing
2657 callout (which could be using a different interface). This has been
2658 changed to use the value of the helo_data option from the smtp transport
2659 instead - this is what is used when a message is actually being sent. If
2660 there is no remote transport (possible with a router that sets up host
2661 addresses), $smtp_active_hostname is used.

7befa435 2664 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2665 (a) The code assumed that strncpy() returns a negative number on buffer
2666 overflow, which isn't the case. Replaced with Exim's string_format()
2667 function.
2668 (b) There were several signed/unsigned issues. I just did the minimum
2669 hacking in of casts. There is scope for a larger refactoring.
2670 (c) The code used strcasecmp() which is not a standard C function.
2671 Replaced with Exim's strcmpic() function.
2672 (d) The code set only $1; it now sets $auth1 as well.
2673 (e) A simple test gave the error "authentication client didn't specify
2674 service in request". It would seem that Dovecot has changed its
2675 interface. Fortunately there's a specification; I followed it and
2676 changed what the client sends and it appears to be working now.

2683 -v the output is "A verified" because verification stops after a
2684 successful redirection if more than one address is generated. However,
2685 with -v the child addresses are also verified. Exim was outputting "A
2686 failed to verify" and then showing the successful verification for C,
2687 with its parentage. It now outputs "B failed to verify", showing B's
2688 parentage before showing the successful verification of C.

2696 they consult the DNS. I had assumed they would set it the way they
2697 wanted; and indeed my experiments on Linux seem to show that in some
2698 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2699 To be on the safe side, however, I have now made the interface to
2700 host_find_byname() similar to host_find_bydns(), with an argument
2701 containing the DNS resolver options. The host_find_byname() function now
2702 sets these options at its start, just as host_find_bydns() does. The smtp
2703 transport options dns_qualify_single and dns_search_parents are passed to
2704 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2705 of host_find_byname() use the default settings of RES_DEFNAMES
2706 (qualify_single) but not RES_DNSRCH (search_parents).

2708PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2709 spool_read_header() do less string testing, by means of a preliminary
2710 switch on the second character of optional "-foo" lines. (This is
2711 overdue, caused by the large number of possibilities that now exist.
2712 Originally there were few.) While I was there, I also converted the
2713 str(n)cmp tests so they don't re-test the leading "-" and the first
2714 character, in the hope this might squeeze out yet more improvement.

2716PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2717 flag allowing group syntax was set by the header_syntax check but not
2718 turned off, possible causing trouble later; (2) The flag was not being
2719 set at all for the header_verify test, causing "group"-style headers to
2720 be rejected. I have now set it in this case, and also caused header_
2721 verify to ignore an empty address taken from a group. While doing this, I
2722 came across some other cases where the code for allowing group syntax
2723 while scanning a header line wasn't quite right (mostly, not resetting
2724 the flag correctly in the right place). These bugs could have caused
2725 trouble for malformed header lines. I hope it is now all correct.

2727PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2728 with the "reply" argument non-NULL. The code, however (which originally
2729 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2730 but it didn't always do it. This confused somebody who was copying the
2731 code for some other use. I have removed all the tests.

PH
2733PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2734 feature that was used to support insecure browsers during the U.S. crypto
2735 embargo. It requires special client support, and Exim is probably the
2736 only MTA that supported it -- and would never use it because real RSA is
2737 always available. This code has been removed, because it had the bad
2738 effect of slowing Exim down by computing (never used) parameters for the
2739 RSA_EXPORT functionality.

2741PH/21 On the advice of Timo Sirainen, added a check to the dovecot

2744 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2745 if the connection is using TLS or if the remote IP is the same as the
2746 local IP, and the "valid-client-cert option" if a client certificate has
2747 been verified.

2778
2779PH/30 Exim was sometimes attempting to deliver messages that had suffered
2780 address errors (4xx response to RCPT) over the same connection as other
2781 messages routed to the same hosts. Such deliveries are always "forced",
2782 so retry times are not inspected. This resulted in far too many retries
2783 for the affected addresses. The effect occurred only when there were more
2784 hosts than the hosts_max_try setting in the smtp transport when it had
2785 the 4xx errors. Those hosts that it had tried were not added to the list
2786 of hosts for which the message was waiting, so if all were tried, there
2787 was no problem. Two fixes have been applied:
2788
2789 (i) If there are any address or message errors in an SMTP delivery, none
2790 of the hosts (tried or untried) are now added to the list of hosts
2791 for which the message is waiting, so the message should not be a
2792 candidate for sending over the same connection that was used for a
2793 successful delivery of some other message. This seems entirely
2794 reasonable: after all the message is NOT "waiting for some host".
2795 This is so "obvious" that I'm not sure why it wasn't done
2796 previously. Hope I haven't missed anything, but it can't do any
2797 harm, as the worst effect is to miss an optimization.
2798
2799 (ii) If, despite (i), such a delivery is accidentally attempted, the
2800 routing retry time is respected, so at least it doesn't keep
2801 hammering the server.

2817 written to the panic log as well as the main log, but it isn't really

2819 removed the panic log writing for the ECONNRESET error when getsockname()
2820 fails.
2821
48c7f9e2
PH
2822PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2823 runs only) independently of the message's sender address. This meant
2824 that, if the 4xx error was in fact related to the sender, a different
2825 message to the same recipient with a different sender could confuse
4c04137d 2826 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2827 server, but other circumstances could also provoke similar problems.
2828 I have changed the default so that the retry time for these errors is now
2829 based a combination of the sender and recipient addresses. This change
2830 can be overridden by setting address_retry_include_sender=false in the
2831 smtp transport.

3080 This bug exists in every version of Exim that I still have, right back to
3081 0.12.

3083PH/26 (n)wildlsearch lookups are documented as being done case-insensitively.
3084 However, an attempt to turn on case-sensitivity in a regex key by
3085 including (?-i) didn't work because the subject string was already
3086 lowercased, and the effects were non-intuitive. It turns out that a
3087 one-line patch can be used to allow (?-i) to work as expected.

3099PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
3100 "Deny" causes Exim to reject the incoming connection with a 554 error.
3101 Unfortunately, if there is a major crisis, such as a disk failure,
3102 tcp-wrappers gives "deny", whereas what one would like would be some
3103 kind of temporary error. A kludge has been added to help with this.
3104 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
3105 554 error is used if errno is still zero or contains ENOENT (which occurs
3106 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
3107 451 error is used.

3129PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
3130 folder from quota calculations, a direct delivery into this folder messed
3131 up the contents of the maildirsize file. This was because the regex was
3132 used only to exclude .Trash (or whatever) when the size of the mailbox
3133 was calculated. There was no check that a delivery was happening into an
3134 excluded directory. This bug has been fixed by ignoring all quota
3135 processing for deliveries into excluded directories.

3140Exim version 4.61
3141-----------------
3142
3143PH/01 The code for finding all the local interface addresses on a FreeBSD
3144 system running IPv6 was broken. This may well have applied to all BSD
3145 systems, as well as to others that have similar system calls. The broken
3146 code found IPv4 interfaces correctly, but gave incorrect values for the
3147 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
3148 that it would not match correctly against @[] and not recognize the IPv6
3149 addresses as local.

3156PH/04 Changed $reply_address to use the raw form of the headers instead of the
3157 decoded form, because it is most often used to construct To: headers
3158 lines in autoreplies, and the decoded form may well be syntactically
3159 invalid. However, $reply_address has leading white space removed, and all
3160 newlines turned into spaces so that the autoreply transport does not
3161 grumble.

3169 spool files has been maintained. However, going back to a previous Exim
3170 release will lost any variables that are in spool files.

3189PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
3190 syntactically invalid From: or Reply-to: line, and a filter used this to
3191 generate an autoreply, and therefore failed to obtain an address for the
3192 autoreply, Exim could try to deliver to a non-existent relative file
3193 name, causing unrelated and misleading errors. What now happens is that
3194 it logs this as a hard delivery error, but does not attempt to create a
3195 bounce message.

3204PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was

3207 literals of the form [IPV4:n.n.n.n] are now always recognized.

3209PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
3210 used if the router is not running as root, for example, when verifying at
3211 ACL time, or when using -bh. The debugging output from this situation was
3212 non-existent - all you got was a failure to exec. I have made two
3213 changes:
3214
3215 (a) Failures to set uid/gid, the current directory, or a process leader
3216 in a subprocess such as that created by queryprogram now generate
4c04137d 3217 suitable debugging output when -d is set.
59e82a2a
PH
3218
3219 (b) The queryprogram router detects when it is not running as root,

3221 the subprocess without attempting to change uid/gid.

PH
3226PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
3227 additional section of a DNS packet that returns MX or SRV records.
3228 Instead, it always explicitly searches for A/AAAA records. This avoids
3229 major problems that occur when a DNS server includes only records of one
3230 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3231 fixed another bug: if SRV records were looked up and the corresponding
3232 address records were *not* found in the additional section, the port
3233 values from the SRV records were lost.

3235PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

3238
064a94c9
PH
3239PH/18 If quota_warn_message contains a From: header, Exim now refrains from
3240 adding the default one. Similarly, if it contains a Reply-To: header, the
3241 errors_reply_to option, if set, is not used.
3242
727071f8
PH
3243PH/19 When calculating a retry time, Exim used to measure the "time since
3244 failure" by looking at the "first failed" field in the retry record. Now
3245 it does not use this if it is later than than the arrival time of the
3246 message. Instead it uses the arrival time. This makes for better
3247 behaviour in cases where some deliveries succeed, thus re-setting the
3248 "first failed" field. An example is a quota failure for a huge message
3249 when small messages continue to be delivered. Without this change, the
3250 "time since failure" will always be short, possible causing more frequent
3251 delivery attempts for the huge message than are intended.
