9-----------------

11JH/01 Rework error string handling in TLS interface so that the caller in
12 more cases is responsible for logging. This permits library-sourced
13 string to be attached to addresses during delivery, and collapses
14 pairs of long lines into single ones.

16PP/01 Allow PKG_CONFIG_PATH to be set in Local/Makefile and use it correctly
17 during configuration. Wildcards are allowed and expanded.

19JH/02 Rework error string handling in DKIM to pass more info back to callers.
20 This permits better logging.
21
875512a3
JH
22JH/03 Rework the transport continued-connection mechanism: when TLS is active,
23 do not close it down and have the child transport start it up again on
24 the passed-on TCP connection. Instead, proxy the child (and any
25 subsequent ones) for TLS via a unix-domain socket channel. Logging is
26 affected: the continued delivery log lines do not have any DNSSEC, TLS
5013d912 27 Certificate or OCSP information. TLS cipher information is still logged.

29JH/04 Shorten the log line for daemon startup by collapsing adjacent sets of
30 identical IP addresses on different listening ports. Will also affect
31 "exiwhat" output.

JH
40JH/06 Default openssl_options to include +no_ticket, to reduce load on peers.
41 Disable the session-cache too, which might reduce our load. Since we
42 currrectly use a new context for every connection, both as server and
43 client, there is no benefit for these.
44 GnuTLS appears to not support tickets server-side by default (we don't
45 call gnutls_session_ticket_enable_server()) but client side is enabled
46 by default on recent versions (3.1.3 +) unless the PFS priority string
47 is used (3.2.4 +).

JH
52JH/07 Fix smtp transport use of limited max_rcpt under mua_wrapper. Previously
53 the check for any unsuccessful recipients did not notice the limit, and
54 erroneously found still-pending ones.
55

JH
56JH/08 Pipeline CHUNKING command and data together, on kernels that support
57 MSG_MORE. Only in-clear (not on TLS connections).
58
42055a33
JH
59JH/09 Avoid using a temporary file during transport using dkim. Unless a
60 transport-filter is involved we can buffer the headers in memory for
61 creating the signature, and read the spool data file once for the
62 signature and again for transmission.
63
eeb35890
JH
64JH/10 Enable use of sendfile in Linux builds as default. It was disabled in
65 4.77 as the kernel support then wasn't solid, having issues in 64bit
7d758a6a 66 mode. Now, it's been long enough. Add support for FreeBSD also.

JH
68JH/11 Bug 2104: Fix continued use of a transport connection with TLS. In the
69 case where the routing stage had gathered several addresses to send to
70 a host before calling the transport for the first, we previously failed
71 to close down TLS in the old transport process before passing the TCP
72 connection to the new process. The new one sent a STARTTLS command
73 which naturally failed, giving a failed delivery and bloating the retry
74 database. Investigation and fix prototype from Wolfgang Breyha.
75
40525d07
JH
76JH/12 Fix check on SMTP command input synchronisation. Previously there were
77 false-negatives in the check that the sender had not preempted a response
78 or prompt from Exim (running as a server), due to that code's lack of
a5ffa9b4 79 awareness of the SMTP input buffering.
40525d07 80
f33875c3
PP
81PP/04 Add commandline_checks_require_admin option.
82 Exim drops privileges sanely, various checks such as -be aren't a
83 security problem, as long as you trust local users with access to their
84 own account. When invoked by services which pass untrusted data to
85 Exim, this might be an issue. Set this option in main configuration
86 AND make fixes to the calling application, such as using `--` to stop
87 processing options.
88
a5ffa9b4
JH
89JH/13 Do pipelining under TLS. Previously, although safe, no advantage was
90 taken. Now take care to pack both (client) MAIL,RCPT,DATA, and (server)
91 responses to those, into a single TLS record each way (this usually means
92 a single packet). As a side issue, smtp_enforce_sync now works on TLS
93 connections.

PP
95PP/05 OpenSSL/1.1: use DH_bits() for more accurate DH param sizes. This
96 affects you only if you're dancing at the edge of the param size limits.
97 If you are, and this message makes sense to you, then: raise the
98 configured limit or use OpenSSL 1.1. Nothing we can do for older
99 versions.

140JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.

142 by IANA as a service extension. However, John Klensin suggests that we
143 should.

164 missing a body hash (the bh= tag).
165
166JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
167 It seems that HAProxy sends the Proxy Protocol information in clear and
168 only then does a TLS startup, so do the same.
169
170JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
171 TCP connections (such as for Spamd) unless the daemon successfully set
172 Fast Open mode on its listening sockets. This fixes breakage seen on
173 too-old kernels or those not configured for Fast Open, at the cost of
174 requiring both directions being enabled for TFO, and TFO never being used
175 by non-daemon-related Exim processes.
176
177JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
178 endings, at least on the first header line. Try to canonify any that get
179 past that check, despite the cost.

193JH/16 Drop variables when they go out of scope. Memory management drops a whole
194 region in one operation, for speed, and this leaves assigned pointers
195 dangling. Add checks run only under the testsuite which checks all
196 variables at a store-reset and panics on a dangling pointer; add code
197 explicitly nulling out all the variables discovered. Fixes one known
198 bug: a transport crash, where a dangling pointer for $sending_ip_address
199 originally assigned in a verify callout, is re-used.

JH
236JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
237 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
238 or even an in-clear connection were permitted. Now, if the host lookup
239 was dnssec and dane was requested then the host is only used if the
240 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
241 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
242 if one fails this test.
243 This means that a poorly-configured remote DNS will make it incommunicado;
244 but it protects against a DNS-interception attack on it.

266JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
267 a cutthrough deliver is pending, as we always want to make a connection.
268 This also avoids re-routing the message when later placing the cutthrough
269 connection after a verify cache hit.

806
807 When a message was received over SMTP with TLS, Exim failed to clear up
808 the incoming connection properly after forking off the child process to
809 deliver the message. In some situations the subsequent outgoing
810 delivery connection happened to have the same fd number as the incoming
811 connection previously had. Exim would try to use TLS and fail, logging
812 a "Bad file descriptor" error.

1058TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
1059
1060 When a queue runner is handling a message, Exim first routes the
1061 recipient addresses, during which it prunes them based on the retry
1062 hints database. After that it attempts to deliver the message to
1063 any remaining recipients. It then updates the hints database using
1064 the retry rules.
1065
1066 So if a recipient address works intermittently, it can get repeatedly
1067 deferred at routing time. The retry hints record remains fresh so the
1068 address never reaches the final cutoff time.
1069
1070 This is a fairly common occurrence when a user is bumping up against
1071 their storage quota. Exim had some logic in its local delivery code
1072 to deal with this. However it did not apply to per-recipient defers
1073 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
1074
1ddeb334
TF
1075 This change adds a proper retry rule check during routing so that the
1076 final cutoff time is checked against the message's age. We only do
1077 this check if there is an address retry record and there is not a
1078 domain retry record; this implies that previous attempts to handle
1079 the address had the retry_use_local_parts option turned on. We use
1080 this as an approximation for the destination being like a local
1081 delivery, as in LMTP.
67bd1ab3
TF
1082
1083 I suspect this new check makes the old local delivery cutoff check
1084 redundant, but I have not verified this so I left the code in place.

1406TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1407 lock up or crash if it happened to be inside a call to libc when it
1408 got a SIGUSR1 from exiwhat.
1409
1410 The SIGUSR1 handler appends the current process status to the process
1411 log which is later printed by exiwhat. It used to use the general
1412 purpose logging code to do this, but several functions it calls are
1413 not safe for signals.
1414
1415 The new output code in the SIGUSR1 handler is specific to the process
1416 log, and simple enough that it's easy to inspect for signal safety.
1417 Removing some special cases also simplifies the general logging code.
1418 Removing the spurious timestamps from the process log simplifies
1419 exiwhat.

TF
1421TF/04 Improved ratelimit ACL condition.
1422
1423 The /noupdate option has been deprecated in favour of /readonly which
1424 has clearer semantics. The /leaky, /strict, and /readonly update modes
1425 are mutually exclusive. The update mode is no longer included in the
1426 database key; it just determines when the database is updated. (This
4c04137d 1427 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1428
1429 Exim now checks that the per_* options are used with an update mode that
1430 makes sense for the current ACL. For example, when Exim is processing a
1431 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1432 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1433 must specify per_mail/readonly. If you omit the update mode it defaults to
1434 /leaky where that makes sense (as before) or /readonly where required.
1435
1436 The /noupdate option is now undocumented but still supported for
1437 backwards compatibility. It is equivalent to /readonly except that in
1438 ACLs where /readonly is required you may specify /leaky/noupdate or
1439 /strict/noupdate which are treated the same as /readonly.
1440
1441 A useful new feature is the /count= option. This is a generalization
1442 of the per_byte option, so that you can measure the throughput of other
1443 aggregate values. For example, the per_byte option is now equivalent
1444 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1445
1446 The per_rcpt option has been generalized using the /count= mechanism
1447 (though it's more complicated than the per_byte equivalence). When it is
1448 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1449 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1450 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1451 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1452 Note that using per_rcpt with a non-readonly update mode in more than
1453 one ACL will cause the recipients to be double-counted. (The per_mail
1454 and per_byte options don't have this problem.)
1455
1456 The handling of very low rates has changed slightly. If the computed rate
1457 is less than the event's count (usually one) then this event is the first
1458 after a long gap. In this case the rate is set to the same as this event's
1459 count, so that the first message of a spam run is counted properly.
1460
1461 The major new feature is a mechanism for counting the rate of unique
1462 events. The new per_addr option counts the number of different
1463 recipients that someone has sent messages to in the last time period. It
1464 behaves like per_rcpt if all the recipient addresses are different, but
1465 duplicate recipient addresses do not increase the measured rate. Like
1466 the /count= option this is a general mechanism, so the per_addr option
1467 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1468 example, measure the rate that a client uses different sender addresses
1469 with the options per_mail/unique=$sender_address. There are further
1470 details in the main documentation.

2020 Note to Michael Haardt: I had to rename some vars in sieve.c. They
2021 were called 'true' and it seems that C99 defines that as a reserved
2022 keyword to be used with 'bool' variable types. That means you could
2023 not include C99-style headers which use bools without triggering

2040-----------------
2041
2042PH/01 Another patch from the Sieve maintainer.
2043
6a3bceb1
PH
2044PH/02 When an IPv6 address is converted to a string for single-key lookup
2045 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
2046 dots are used instead of colons so that keys in lsearch files need not
2047 contain colons. This was done some time before quoting was made available
2048 in lsearch files. However, iplsearch files do require colons in IPv6 keys
2049 (notated using the quote facility) so as to distinguish them from IPv4
2050 keys. This meant that lookups for IP addresses in host lists did not work
2051 for iplsearch lookups.
2052
2053 This has been fixed by arranging for IPv6 addresses to be expressed with
2054 colons if the lookup type is iplsearch. This is not incompatible, because
2055 previously such lookups could never work.
2056
4c04137d 2057 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
2058 ordinary lsearch keys. However, making the change in all cases is
2059 incompatible and would probably break a number of configurations.
2060

2063
0806a9c5
MH
2064MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
2065 conversion specification without a maximum field width, thereby enabling
2066 a rogue spamd server to cause a buffer overflow. While nobody in their
2067 right mind would setup Exim to query an untrusted spamd server, an
2068 attacker that gains access to a server running spamd could potentially
2069 exploit this vulnerability to run arbitrary code as the Exim user.

2073
0f2cbd1b
MH
2074MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
2075 a directory entry by the name of the lookup key. Previously, if a
2076 symlink pointed to a non-existing file or a file in a directory that
2077 Exim lacked permissions to read, a lookup for a key matching that
2078 symlink would fail. Now it is enough that a matching directory entry
2079 exists, symlink or not. (Bugzilla 503.)

2152PH/02 In an ACL statement such as

2156 if a client was not listed at all, or was listed with a value other than
2157 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
2158 the condition was not true (as it should be), so access was not denied.

PH
2262PH/29 SMTP synchronization checks are implemented when a command is read -
2263 there is a check that no more input is waiting when there shouldn't be
2264 any. However, for some commands, a delay in an ACL can mean that it is
2265 some time before the response is written. In this time, more input might
2266 arrive, invalidly. So now there are extra checks after an ACL has run for
2267 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2268 pipelining has not been advertised.

PH
2280PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in

2283 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2284 was a macro that became an assignment, so it seemed to work. This has
2285 changed to a proper function call with a void return, hence the compile
2286 error. Exim's code has been fixed.

2314PH/40 When Exim receives a message, it writes the login name, uid, and gid of
2315 whoever called Exim into the -H file. In the case of the daemon it was
2316 behaving confusingly. When first started, it used values for whoever
2317 started the daemon, but after a SIGHUP it used the Exim user (because it
2318 calls itself on a restart). I have changed the code so that it now always
2319 uses the Exim user.

2321PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

2323 sender address), and a DATA command is nevertheless sent (as can happen
2324 with PIPELINING or a stupid MUA), the error message that was given to the
2325 RCPT commands is included in the rejection of the DATA command. This is
2326 intended to be helpful for MUAs that show only the final error to their
2327 users.

58eb016e 2341PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
2342 the response to the final '.' that terminates a message, but only in the
2343 case where the client has not sent further data following the '.'
2344 (unfortunately, this is allowed). However, in many cases there won't be
2345 any further data because there won't be any more messages to send. A call
2346 to select() can be used: if it shows that the input is "ready", there is
2347 either input waiting, or the socket has been closed. An attempt to read
2348 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2349 would have sent an OK response which the client would never have see.

2357Exim version 4.66
2358-----------------
2359
2360PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2361 fixed by 4.65/MH/01 (is this a record?) are fixed:
2362
2363 (i) An empty string was always treated as zero by the numeric comparison
2364 operators. This behaviour has been restored.
2365
2366 (ii) It is documented that the numeric comparison operators always treat
2367 their arguments as decimal numbers. This was broken in that numbers
2368 starting with 0 were being interpreted as octal.
2369
2370 While fixing these problems I realized that there was another issue that
2371 hadn't been noticed. Values of message_size_limit (both the global option
2372 and the transport option) were treated as octal if they started with 0.
2373 The documentation was vague. These values are now always treated as
2374 decimal, and I will make that clear in the documentation.

2388PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

2390 is held in a short int, deliveries were likely to be lost. As such a
2391 large number of recipients for a single message is ridiculous
2392 (performance will be very, very poor), I have chosen to impose a limit
2393 rather than extend the field.

2399TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2400 leftover -K file (the existence of which was triggered by #402).

2409TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
2418PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2419 callout verification, Exim cached a "reject" for the entire domain. This
2420 is correct for most verifications, but it is not correct for a recipient
2421 verification with use_sender or use_postmaster set, because in that case
2422 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2423 case of MAIL FROM:<> rejection from other early rejections (e.g.
2424 rejection of HELO). When verifying a recipient using a non-null MAIL
2425 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2426 Whatever the result of the callout, the value of the domain cache is
2427 left unchanged (for any other kind of callout, getting as far as trying
2428 RCPT means that the domain itself is ok).

2464 probably the interface on which it is arriving) and not to the outgoing
2465 callout (which could be using a different interface). This has been
2466 changed to use the value of the helo_data option from the smtp transport
2467 instead - this is what is used when a message is actually being sent. If
2468 there is no remote transport (possible with a router that sets up host
2469 addresses), $smtp_active_hostname is used.

7befa435 2472 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2473 (a) The code assumed that strncpy() returns a negative number on buffer
2474 overflow, which isn't the case. Replaced with Exim's string_format()
2475 function.
2476 (b) There were several signed/unsigned issues. I just did the minimum
2477 hacking in of casts. There is scope for a larger refactoring.
2478 (c) The code used strcasecmp() which is not a standard C function.
2479 Replaced with Exim's strcmpic() function.
2480 (d) The code set only $1; it now sets $auth1 as well.
2481 (e) A simple test gave the error "authentication client didn't specify
2482 service in request". It would seem that Dovecot has changed its
2483 interface. Fortunately there's a specification; I followed it and
2484 changed what the client sends and it appears to be working now.

2490 address A is aliased to B and C, where B exists and C does not. Without
2491 -v the output is "A verified" because verification stops after a
2492 successful redirection if more than one address is generated. However,
2493 with -v the child addresses are also verified. Exim was outputting "A
2494 failed to verify" and then showing the successful verification for C,
2495 with its parentage. It now outputs "B failed to verify", showing B's
2496 parentage before showing the successful verification of C.

322050c2
PH
2502PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2503 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2504 they consult the DNS. I had assumed they would set it the way they
2505 wanted; and indeed my experiments on Linux seem to show that in some
2506 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2507 To be on the safe side, however, I have now made the interface to
2508 host_find_byname() similar to host_find_bydns(), with an argument
2509 containing the DNS resolver options. The host_find_byname() function now
2510 sets these options at its start, just as host_find_bydns() does. The smtp
2511 transport options dns_qualify_single and dns_search_parents are passed to
2512 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2513 of host_find_byname() use the default settings of RES_DEFNAMES
2514 (qualify_single) but not RES_DNSRCH (search_parents).

2517 spool_read_header() do less string testing, by means of a preliminary
2518 switch on the second character of optional "-foo" lines. (This is
2519 overdue, caused by the large number of possibilities that now exist.
2520 Originally there were few.) While I was there, I also converted the
2521 str(n)cmp tests so they don't re-test the leading "-" and the first
2522 character, in the hope this might squeeze out yet more improvement.

2524PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2525 flag allowing group syntax was set by the header_syntax check but not
2526 turned off, possible causing trouble later; (2) The flag was not being
2527 set at all for the header_verify test, causing "group"-style headers to
2528 be rejected. I have now set it in this case, and also caused header_
2529 verify to ignore an empty address taken from a group. While doing this, I
2530 came across some other cases where the code for allowing group syntax
2531 while scanning a header line wasn't quite right (mostly, not resetting
2532 the flag correctly in the right place). These bugs could have caused
2533 trouble for malformed header lines. I hope it is now all correct.

2535PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2537 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2538 but it didn't always do it. This confused somebody who was copying the
2539 code for some other use. I have removed all the tests.

PH
2541PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2542 feature that was used to support insecure browsers during the U.S. crypto
2543 embargo. It requires special client support, and Exim is probably the
2544 only MTA that supported it -- and would never use it because real RSA is
2545 always available. This code has been removed, because it had the bad
2546 effect of slowing Exim down by computing (never used) parameters for the
2547 RSA_EXPORT functionality.

2552 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2553 if the connection is using TLS or if the remote IP is the same as the
2554 local IP, and the "valid-client-cert option" if a client certificate has
2555 been verified.

2586
2587PH/30 Exim was sometimes attempting to deliver messages that had suffered
2588 address errors (4xx response to RCPT) over the same connection as other
2589 messages routed to the same hosts. Such deliveries are always "forced",
2590 so retry times are not inspected. This resulted in far too many retries
2591 for the affected addresses. The effect occurred only when there were more
2592 hosts than the hosts_max_try setting in the smtp transport when it had
2593 the 4xx errors. Those hosts that it had tried were not added to the list
2594 of hosts for which the message was waiting, so if all were tried, there
2595 was no problem. Two fixes have been applied:
2596
2597 (i) If there are any address or message errors in an SMTP delivery, none
2598 of the hosts (tried or untried) are now added to the list of hosts
2599 for which the message is waiting, so the message should not be a
2600 candidate for sending over the same connection that was used for a
2601 successful delivery of some other message. This seems entirely
2602 reasonable: after all the message is NOT "waiting for some host".
2603 This is so "obvious" that I'm not sure why it wasn't done
2604 previously. Hope I haven't missed anything, but it can't do any
2605 harm, as the worst effect is to miss an optimization.
2606
2607 (ii) If, despite (i), such a delivery is accidentally attempted, the
2608 routing retry time is respected, so at least it doesn't keep
2609 hammering the server.

48c7f9e2
PH
2630PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2631 runs only) independently of the message's sender address. This meant
2632 that, if the 4xx error was in fact related to the sender, a different
2633 message to the same recipient with a different sender could confuse
4c04137d 2634 things. In particular, this can happen when sending to a greylisting

2635 server, but other circumstances could also provoke similar problems.
2636 I have changed the default so that the retry time for these errors is now

2907PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2909 Unfortunately, if there is a major crisis, such as a disk failure,
2910 tcp-wrappers gives "deny", whereas what one would like would be some
2911 kind of temporary error. A kludge has been added to help with this.
2912 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2913 554 error is used if errno is still zero or contains ENOENT (which occurs
2914 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2954 code found IPv4 interfaces correctly, but gave incorrect values for the
2955 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

3000 autoreply, Exim could try to deliver to a non-existent relative file

3036 Instead, it always explicitly searches for A/AAAA records. This avoids
3037 major problems that occur when a DNS server includes only records of one
3038 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
3039 fixed another bug: if SRV records were looked up and the corresponding
3040 address records were *not* found in the additional section, the port
3041 values from the SRV records were lost.

PH
3051PH/19 When calculating a retry time, Exim used to measure the "time since
3052 failure" by looking at the "first failed" field in the retry record. Now
3053 it does not use this if it is later than than the arrival time of the
3054 message. Instead it uses the arrival time. This makes for better
3055 behaviour in cases where some deliveries succeed, thus re-setting the
3056 "first failed" field. An example is a quota failure for a huge message
3057 when small messages continue to be delivered. Without this change, the
3058 "time since failure" will always be short, possible causing more frequent
3059 delivery attempts for the huge message than are intended.

3089PH/27 If a host name lookup failed very early in a connection, for example, if
3090 the IP address matched host_lookup and the reverse lookup yielded a name
3091 that did not have a forward lookup, an error message of the form "no IP
3092 address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
3093 could be logged. Now it outputs the IP address instead of "NULL".

3098 documented for local_scan(), the new function should be too.

3127PH/36 Now that the new test suite is complete, we can remove some of the
3128 special code in Exim that was needed for the old test suite. For example,
3129 sorting DNS records because real resolvers return them in an arbitrary

3131 same order.

PH
3156PH/42 The content-scanning code uses fopen() to create files in which to put
3157 message data. Previously it was not paying any attention to the mode of
3158 the files. Exim runs with umask(0) because the rest of the code creates
3159 files with open(), and sets the required mode explicitly. Thus, these
3160 files were ending up world-writeable. This was not a big issue, because,
3161 being within the spool directory, they were not world-accessible. I have
3162 created a function called modefopen, which takes an additional mode
3163 argument. It sets umask(777), creates the file, chmods it to the required
3164 mode, then resets the umask. All the relevant calls to fopen() in the
3165 content scanning code have been changed to use this function.

PH
3173PH/45 When the plaintext authenticator is running as a client, the server's
3174 challenges are checked to ensure they are valid base64 strings. By
3175 default, the authentication attempt is cancelled if an invalid string is
3176 received. Setting client_ignore_invalid_base64 true ignores these errors.
3177 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
3178 they are received. Thus, the responses can be made to depend on the
3179 challenges. If an invalid string is ignored, an empty string is placed in
3180 the variable.

3191PH/50 When an Exim quota was set without a file count quota, and mailbox_size
3192 was also set, the appendfile transport was unnecessarily scanning a
3193 directory of message files (e.g. for maildir delivery) to find the count
3194 of files (along with the size), even though it did not need this
3195 information. It now does the scan only if it needs to find either the
3196 size of the count of files.

3200PH/52 Two bugs concerned with error handling when the smtp transport is
3201 used in LMTP mode:
3202
3203 (i) Exim was not creating retry information for temporary errors given
3204 for individual recipients after the DATA command when the smtp transport
3205 was used in LMTP mode. This meant that they could be retried too
3206 frequently, and not timed out correctly.
3207
3208 (ii) Exim was setting the flag that allows error details to be returned
3209 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3210 recipients that were returned after the DATA command.
3211
3212PH/53 This is related to PH/52, but is more general: for any failing address,
3213 when detailed error information was permitted to be returned to the
3214 sender, but the error was temporary, then after the final timeout, only
3215 "retry timeout exceeded" was returned. Now it returns the full error as
3216 well as "retry timeout exceeded".
