7JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
8 and 3.4.4 - once the server is enabled to respond to an OCSP request
9 it does even when not requested, resulting in a stapling non-aware
10 client dropping the TLS connection.

15TF/02 Improve the consistency of logging incoming and outgoing interfaces.
16 The I= interface field on outgoing lines is now after the H= remote
17 host field, same as incoming lines. There is a separate
18 outgoing_interface log selector which allows you to disable the
19 outgoing I= field.

30 it.
31
01a4a5c5 32JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 33 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
34 can be used to disable this per-host. The build option
35 EXPERIMENTAL_CERTNAMES is withdrawn.
36
cb1d7830 37JH/05 The value of the tls_verify_certificates smtp transport and main options

39 For GnuTLS, only version 3.0.20 or later.
40
610ff438 41JH/06 Verification of the server certificate for a TLS connection is now tried

46JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
47 sites use this now.
48
50dc7409
JH
49JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
50 Status Notification (bounce) messages are now MIME format per RFC 3464.
51 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
52 under the control of the dsn_advertise_hosts option, and routers may

117 Normally benign, it bites when the pair was led to by a CNAME;
118 modern usage is to not canoicalize the domain to a CNAME target
119 (and we were inconsistent anyway for A-only vs AAAA+A).

142Exim version 4.85
143-----------------
144TL/01 When running the test suite, the README says that variables such as
145 no_msglog_check are global and can be placed anywhere in a specific
146 test's script, however it was observed that placement needed to be near
147 the beginning for it to behave that way. Changed the runtest perl
148 script to read through the entire script once to detect and set these
149 variables, reset to the beginning of the script, and then run through
150 the script parsing/test process like normal.

160TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
161 syntax errors in an expansion can be treated as a string instead of
162 logging or causing an error, due to the internal use of bool_lax
163 instead of bool when processing it.

WB
177JH/05 Fix results-pipe from transport process. Several recipients, combined
178 with certificate use, exposed issues where response data items split
179 over buffer boundaries were not parsed properly. This eventually
180 resulted in duplicates being sent. This issue only became common enough
181 to notice due to the introduction of conection certificate information,
182 the item size being so much larger. Found and fixed by Wolfgang Breyha.
183

184JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed

191JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
192 is EXPERIMENTAL_EVENT, the main-configuration and transport options
193 both become "event_action", the variables become $event_name, $event_data
aec45841 194 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
195 routers, transports and related events. The tls:cert event is now also
196 raised for inbound connections, if the main configuration event_action
197 option is defined.

252-----------------
253
254TF/01 Correctly close the server side of TLS when forking for delivery.
255
256 When a message was received over SMTP with TLS, Exim failed to clear up
257 the incoming connection properly after forking off the child process to
258 deliver the message. In some situations the subsequent outgoing
259 delivery connection happened to have the same fd number as the incoming
260 connection previously had. Exim would try to use TLS and fail, logging
261 a "Bad file descriptor" error.

507TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
508
509 When a queue runner is handling a message, Exim first routes the
510 recipient addresses, during which it prunes them based on the retry
511 hints database. After that it attempts to deliver the message to
512 any remaining recipients. It then updates the hints database using
513 the retry rules.
514
515 So if a recipient address works intermittently, it can get repeatedly
516 deferred at routing time. The retry hints record remains fresh so the
517 address never reaches the final cutoff time.
518
519 This is a fairly common occurrence when a user is bumping up against
520 their storage quota. Exim had some logic in its local delivery code
521 to deal with this. However it did not apply to per-recipient defers
522 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
523
1ddeb334
TF
524 This change adds a proper retry rule check during routing so that the
525 final cutoff time is checked against the message's age. We only do
526 this check if there is an address retry record and there is not a
527 domain retry record; this implies that previous attempts to handle
528 the address had the retry_use_local_parts option turned on. We use
529 this as an approximation for the destination being like a local
530 delivery, as in LMTP.
67bd1ab3
TF
531
532 I suspect this new check makes the old local delivery cutoff check
533 redundant, but I have not verified this so I left the code in place.

540
541 When I ran the test suite under the user fanf2, Exim expanded
542 the header to contain my full name, whereas it should have added
543 a Resent-Sender: header. It erroneously treats any prefix of the
544 username as equal to the username.

546 This change corrects that bug.

568 Server implementation by Todd Lyons, client by JH.
569 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
570 config variable "prdr_enable" controls whether the server
571 advertises the facility. If the client requests PRDR a new
572 acl_data_smtp_prdr ACL is called once for each recipient, after
573 the body content is received and before the acl_smtp_data ACL.
574 The client is controlled by bolth of: a hosts_try_prdr option
575 on the smtp transport, and the server advertisement.
576 Default client logging of deliveries and rejections involving
577 PRDR are flagged with the string "PRDR".

855TF/03 Make the exiwhat support code safe for signals. Previously Exim might
856 lock up or crash if it happened to be inside a call to libc when it
857 got a SIGUSR1 from exiwhat.
858
859 The SIGUSR1 handler appends the current process status to the process
860 log which is later printed by exiwhat. It used to use the general
861 purpose logging code to do this, but several functions it calls are
862 not safe for signals.
863
864 The new output code in the SIGUSR1 handler is specific to the process
865 log, and simple enough that it's easy to inspect for signal safety.
866 Removing some special cases also simplifies the general logging code.
867 Removing the spurious timestamps from the process log simplifies
868 exiwhat.

870TF/04 Improved ratelimit ACL condition.
871
872 The /noupdate option has been deprecated in favour of /readonly which
873 has clearer semantics. The /leaky, /strict, and /readonly update modes
874 are mutually exclusive. The update mode is no longer included in the
875 database key; it just determines when the database is updated. (This
876 means that when you upgrde Exim will forget old rate measurements.)
877
878 Exim now checks that the per_* options are used with an update mode that
879 makes sense for the current ACL. For example, when Exim is processing a
880 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
881 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
882 must specify per_mail/readonly. If you omit the update mode it defaults to
883 /leaky where that makes sense (as before) or /readonly where required.
884
885 The /noupdate option is now undocumented but still supported for
886 backwards compatibility. It is equivalent to /readonly except that in
887 ACLs where /readonly is required you may specify /leaky/noupdate or
888 /strict/noupdate which are treated the same as /readonly.
889
890 A useful new feature is the /count= option. This is a generalization
891 of the per_byte option, so that you can measure the throughput of other
892 aggregate values. For example, the per_byte option is now equivalent
893 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
894
895 The per_rcpt option has been generalized using the /count= mechanism
896 (though it's more complicated than the per_byte equivalence). When it is
897 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
898 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
899 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
900 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
901 Note that using per_rcpt with a non-readonly update mode in more than
902 one ACL will cause the recipients to be double-counted. (The per_mail
903 and per_byte options don't have this problem.)
904
905 The handling of very low rates has changed slightly. If the computed rate
906 is less than the event's count (usually one) then this event is the first
907 after a long gap. In this case the rate is set to the same as this event's
908 count, so that the first message of a spam run is counted properly.
909
910 The major new feature is a mechanism for counting the rate of unique
911 events. The new per_addr option counts the number of different
912 recipients that someone has sent messages to in the last time period. It
913 behaves like per_rcpt if all the recipient addresses are different, but
914 duplicate recipient addresses do not increase the measured rate. Like
915 the /count= option this is a general mechanism, so the per_addr option
916 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
917 example, measure the rate that a client uses different sender addresses
918 with the options per_mail/unique=$sender_address. There are further
919 details in the main documentation.

1491PH/01 Another patch from the Sieve maintainer.
1492
6a3bceb1
PH
1493PH/02 When an IPv6 address is converted to a string for single-key lookup
1494 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1495 dots are used instead of colons so that keys in lsearch files need not
1496 contain colons. This was done some time before quoting was made available
1497 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1498 (notated using the quote facility) so as to distinguish them from IPv4
1499 keys. This meant that lookups for IP addresses in host lists did not work
1500 for iplsearch lookups.
1501
1502 This has been fixed by arranging for IPv6 addresses to be expressed with
1503 colons if the lookup type is iplsearch. This is not incompatible, because
1504 previously such lookups could never work.
1505
1506 The situation is now rather anomolous, since one *can* have colons in
1507 ordinary lsearch keys. However, making the change in all cases is
1508 incompatible and would probably break a number of configurations.

1513MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1514 conversion specification without a maximum field width, thereby enabling
1515 a rogue spamd server to cause a buffer overflow. While nobody in their
1516 right mind would setup Exim to query an untrusted spamd server, an
1517 attacker that gains access to a server running spamd could potentially
1518 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1523MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1524 a directory entry by the name of the lookup key. Previously, if a
1525 symlink pointed to a non-existing file or a file in a directory that
1526 Exim lacked permissions to read, a lookup for a key matching that
1527 symlink would fail. Now it is enough that a matching directory entry
1528 exists, symlink or not. (Bugzilla 503.)

1712 there is a check that no more input is waiting when there shouldn't be

1714 some time before the response is written. In this time, more input might
1715 arrive, invalidly. So now there are extra checks after an ACL has run for
1716 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1717 pipelining has not been advertised.

PH
1791 the response to the final '.' that terminates a message, but only in the
1792 case where the client has not sent further data following the '.'
1793 (unfortunately, this is allowed). However, in many cases there won't be
1794 any further data because there won't be any more messages to send. A call
1795 to select() can be used: if it shows that the input is "ready", there is
1796 either input waiting, or the socket has been closed. An attempt to read
1797 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1798 would have sent an OK response which the client would never have see.

1809PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1810 fixed by 4.65/MH/01 (is this a record?) are fixed:
1811
1812 (i) An empty string was always treated as zero by the numeric comparison
1813 operators. This behaviour has been restored.
1814
1815 (ii) It is documented that the numeric comparison operators always treat
1816 their arguments as decimal numbers. This was broken in that numbers
1817 starting with 0 were being interpreted as octal.
1818
1819 While fixing these problems I realized that there was another issue that
1820 hadn't been noticed. Values of message_size_limit (both the global option
1821 and the transport option) were treated as octal if they started with 0.
1822 The documentation was vague. These values are now always treated as
1823 decimal, and I will make that clear in the documentation.

2b1c6e3a
PH
1867PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1868 callout verification, Exim cached a "reject" for the entire domain. This
1869 is correct for most verifications, but it is not correct for a recipient
1870 verification with use_sender or use_postmaster set, because in that case
1871 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1872 case of MAIL FROM:<> rejection from other early rejections (e.g.
1873 rejection of HELO). When verifying a recipient using a non-null MAIL
1874 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1875 Whatever the result of the callout, the value of the domain cache is
1876 left unchanged (for any other kind of callout, getting as far as trying
1877 RCPT means that the domain itself is ok).

1913 probably the interface on which it is arriving) and not to the outgoing
1914 callout (which could be using a different interface). This has been
1915 changed to use the value of the helo_data option from the smtp transport
1916 instead - this is what is used when a message is actually being sent. If
1917 there is no remote transport (possible with a router that sets up host

7befa435 1921 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1922 (a) The code assumed that strncpy() returns a negative number on buffer
1923 overflow, which isn't the case. Replaced with Exim's string_format()
1924 function.
1925 (b) There were several signed/unsigned issues. I just did the minimum
1926 hacking in of casts. There is scope for a larger refactoring.
1927 (c) The code used strcasecmp() which is not a standard C function.
1928 Replaced with Exim's strcmpic() function.
1929 (d) The code set only $1; it now sets $auth1 as well.
1930 (e) A simple test gave the error "authentication client didn't specify
1931 service in request". It would seem that Dovecot has changed its
1932 interface. Fortunately there's a specification; I followed it and
1933 changed what the client sends and it appears to be working now.

1940 -v the output is "A verified" because verification stops after a
1941 successful redirection if more than one address is generated. However,
1942 with -v the child addresses are also verified. Exim was outputting "A
1943 failed to verify" and then showing the successful verification for C,
1944 with its parentage. It now outputs "B failed to verify", showing B's
1945 parentage before showing the successful verification of C.

1951PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and

1953 they consult the DNS. I had assumed they would set it the way they
1954 wanted; and indeed my experiments on Linux seem to show that in some
1955 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1956 To be on the safe side, however, I have now made the interface to
1957 host_find_byname() similar to host_find_bydns(), with an argument
1958 containing the DNS resolver options. The host_find_byname() function now
1959 sets these options at its start, just as host_find_bydns() does. The smtp
1960 transport options dns_qualify_single and dns_search_parents are passed to
1961 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1962 of host_find_byname() use the default settings of RES_DEFNAMES
1963 (qualify_single) but not RES_DNSRCH (search_parents).

1965PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1966 spool_read_header() do less string testing, by means of a preliminary
1967 switch on the second character of optional "-foo" lines. (This is
1968 overdue, caused by the large number of possibilities that now exist.
1969 Originally there were few.) While I was there, I also converted the
1970 str(n)cmp tests so they don't re-test the leading "-" and the first
1971 character, in the hope this might squeeze out yet more improvement.

1973PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1974 flag allowing group syntax was set by the header_syntax check but not
1975 turned off, possible causing trouble later; (2) The flag was not being
1976 set at all for the header_verify test, causing "group"-style headers to
1977 be rejected. I have now set it in this case, and also caused header_
1978 verify to ignore an empty address taken from a group. While doing this, I
1979 came across some other cases where the code for allowing group syntax
1980 while scanning a header line wasn't quite right (mostly, not resetting
1981 the flag correctly in the right place). These bugs could have caused
1982 trouble for malformed header lines. I hope it is now all correct.

1984PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1986 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1987 but it didn't always do it. This confused somebody who was copying the
1988 code for some other use. I have removed all the tests.

1990PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1991 feature that was used to support insecure browsers during the U.S. crypto
1992 embargo. It requires special client support, and Exim is probably the
1993 only MTA that supported it -- and would never use it because real RSA is
1994 always available. This code has been removed, because it had the bad
1995 effect of slowing Exim down by computing (never used) parameters for the
1996 RSA_EXPORT functionality.

1998PH/21 On the advice of Timo Sirainen, added a check to the dovecot

2001 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2002 if the connection is using TLS or if the remote IP is the same as the
2003 local IP, and the "valid-client-cert option" if a client certificate has
2004 been verified.

2035
2036PH/30 Exim was sometimes attempting to deliver messages that had suffered
2037 address errors (4xx response to RCPT) over the same connection as other
2038 messages routed to the same hosts. Such deliveries are always "forced",
2039 so retry times are not inspected. This resulted in far too many retries
2040 for the affected addresses. The effect occurred only when there were more
2041 hosts than the hosts_max_try setting in the smtp transport when it had
2042 the 4xx errors. Those hosts that it had tried were not added to the list
2043 of hosts for which the message was waiting, so if all were tried, there
2044 was no problem. Two fixes have been applied:
2045
2046 (i) If there are any address or message errors in an SMTP delivery, none
2047 of the hosts (tried or untried) are now added to the list of hosts
2048 for which the message is waiting, so the message should not be a
2049 candidate for sending over the same connection that was used for a
2050 successful delivery of some other message. This seems entirely
2051 reasonable: after all the message is NOT "waiting for some host".
2052 This is so "obvious" that I'm not sure why it wasn't done
2053 previously. Hope I haven't missed anything, but it can't do any
2054 harm, as the worst effect is to miss an optimization.
2055
2056 (ii) If, despite (i), such a delivery is accidentally attempted, the
2057 routing retry time is respected, so at least it doesn't keep
2058 hammering the server.

2073PH/35 The error "getsockname() failed: connection reset by peer" was being
2074 written to the panic log as well as the main log, but it isn't really
2075 panic-worthy as it just means the connection died rather early on. I have
2076 removed the panic log writing for the ECONNRESET error when getsockname()
2077 fails.
2078
48c7f9e2
PH
2079PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2080 runs only) independently of the message's sender address. This meant
2081 that, if the 4xx error was in fact related to the sender, a different
2082 message to the same recipient with a different sender could confuse
2083 things. In particualar, this can happen when sending to a greylisting
2084 server, but other circumstances could also provoke similar problems.
2085 I have changed the default so that the retry time for these errors is now
2086 based a combination of the sender and recipient addresses. This change
2087 can be overridden by setting address_retry_include_sender=false in the
2088 smtp transport.

2347Exim version 4.62
2348-----------------
2349
2350TF/01 Fix the add_header change below (4.61 PH/55) which had a bug that (amongst
2351 other effects) broke the use of negated acl sub-conditions.

2353PH/01 ${readsocket now supports Internet domain sockets (modified John Jetmore
2354 patch).

PH
2356PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2357 "Deny" causes Exim to reject the incoming connection with a 554 error.
2358 Unfortunately, if there is a major crisis, such as a disk failure,
2359 tcp-wrappers gives "deny", whereas what one would like would be some
2360 kind of temporary error. A kludge has been added to help with this.
2361 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2362 554 error is used if errno is still zero or contains ENOENT (which occurs
2363 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2364 451 error is used.

PH
2368PH/04 Change PH/19 for 4.61 was too wide. It should not be applied to host
2369 errors. Otherwise a message that provokes a temporary error (when other
2370 messages do not) can cause a whole host to time out.

PH
2372PH/05 Batch deliveries by appendfile and pipe transports did not work when the
2373 addresses were routed directly to files or pipes from a redirect router.
2374 File deliveries just didn't batch; pipe deliveries might have suffered
2375 odd errors.

2377PH/06 A failure to get a lock for a hints database would erroneously always say
2378 "Failed to get write lock", even when it was really a read lock.
2379
7e9f683d
PH
2380PH/07 The appendfile transport was creating MBX lock files with a fixed mode
2381 of 0600. This has been changed to use the value of the lockfile_mode
2382 option (which defaults to 0600).

2384PH/08 Applied small patch from the Sieve maintainer.

PH
2386PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2387 folder from quota calculations, a direct delivery into this folder messed
2388 up the contents of the maildirsize file. This was because the regex was
2389 used only to exclude .Trash (or whatever) when the size of the mailbox
2390 was calculated. There was no check that a delivery was happening into an
2391 excluded directory. This bug has been fixed by ignoring all quota
2392 processing for deliveries into excluded directories.

2397Exim version 4.61
2398-----------------
2399
2400PH/01 The code for finding all the local interface addresses on a FreeBSD
2401 system running IPv6 was broken. This may well have applied to all BSD
2402 systems, as well as to others that have similar system calls. The broken
2403 code found IPv4 interfaces correctly, but gave incorrect values for the
2404 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2405 that it would not match correctly against @[] and not recognize the IPv6
2406 addresses as local.
2407
f9daeae0
PH
2408PH/02 The ipliteral router was not recognizing addresses of the form user@
2409 [ipv6:....] because it didn't know about the "ipv6:" prefix.
2410
7e66e54d
PH
2411PH/03 Added disable_ipv6.
2412
c8ea1597
PH
2413PH/04 Changed $reply_address to use the raw form of the headers instead of the
2414 decoded form, because it is most often used to construct To: headers
2415 lines in autoreplies, and the decoded form may well be syntactically
2416 invalid. However, $reply_address has leading white space removed, and all
2417 newlines turned into spaces so that the autoreply transport does not
2418 grumble.
2419

PH
2420PH/05 If group was specified without a user on a router, and no group or user
2421 was specified on a transport, the group from the router was ignored.

PH
2423PH/06 Increased the number of ACL variables to 20 of each type, and arranged
2424 for visible compile-time settings that can be used to change these
2425 numbers, for those that want even more. Backwards compatibility with old
2426 spool files has been maintained. However, going back to a previous Exim
2427 release will lost any variables that are in spool files.
2428

PH
2429PH/07 Two small changes when running in the test harness: increase delay when
2430 passing a TCP/IP connection to a new process, in case the original
2431 process has to generate a bounce, and remove special handling of
2432 127.0.0.2 (sic), which is no longer necessary.

2444 in 4.61-PH/06
2445
424a1c63
PH
2446PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
2447 syntactically invalid From: or Reply-to: line, and a filter used this to
2448 generate an autoreply, and therefore failed to obtain an address for the
2449 autoreply, Exim could try to deliver to a non-existent relative file
2450 name, causing unrelated and misleading errors. What now happens is that
2451 it logs this as a hard delivery error, but does not attempt to create a
2452 bounce message.

PH
2454PH/11 The exinext utility has a -C option for testing purposes, but although
2455 the given file was scanned by exinext itself; it wasn't being passed on

PH
2461PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
2462 compiled. In many other places in Exim, IPv6 addresses are always
2463 recognized, so I have changed this. It also means that IPv4 domain
2464 literals of the form [IPV4:n.n.n.n] are now always recognized.
2465
59e82a2a
PH
2466PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
2467 used if the router is not running as root, for example, when verifying at
2468 ACL time, or when using -bh. The debugging output from this situation was
2469 non-existent - all you got was a failure to exec. I have made two
2470 changes:
2471
2472 (a) Failures to set uid/gid, the current directory, or a process leader
2473 in a subprocess such as that created by queryprogram now generate
2474 suitable debugging ouput when -d is set.
2475
2476 (b) The queryprogram router detects when it is not running as root,
2477 outputs suitable debugging information if -d is set, and then runs
2478 the subprocess without attempting to change uid/gid.
2479
9edc04ce
PH
2480PH/15 Minor change to Makefile for building test_host (undocumented testing
2481 feature).
2482
1349e1e5
PH
2483PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2484 additional section of a DNS packet that returns MX or SRV records.
2485 Instead, it always explicitly searches for A/AAAA records. This avoids
2486 major problems that occur when a DNS server includes only records of one
2487 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2488 fixed another bug: if SRV records were looked up and the corresponding
2489 address records were *not* found in the additional section, the port
2490 values from the SRV records were lost.
2491
ea49d0e1
PH
2492PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
2493 using the correct key (the original address) when searching the retry
2494 rules in order to find which one to use for generating the retry hint.
2495
064a94c9
PH
2496PH/18 If quota_warn_message contains a From: header, Exim now refrains from
2497 adding the default one. Similarly, if it contains a Reply-To: header, the
2498 errors_reply_to option, if set, is not used.
2499
727071f8
PH
2500PH/19 When calculating a retry time, Exim used to measure the "time since
2501 failure" by looking at the "first failed" field in the retry record. Now
2502 it does not use this if it is later than than the arrival time of the
2503 message. Instead it uses the arrival time. This makes for better
2504 behaviour in cases where some deliveries succeed, thus re-setting the
2505 "first failed" field. An example is a quota failure for a huge message
2506 when small messages continue to be delivered. Without this change, the
2507 "time since failure" will always be short, possible causing more frequent
2508 delivery attempts for the huge message than are intended.

2511PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as
2512 $1, $2, $3) because the numerical variables can be reset during some
2513 expansion items (e.g. "match"), thereby losing the authentication data.

2518PH/22 Test the values given for quota, quota_filecount, quota_warn_threshold,
2519 mailbox_size, and mailbox_filecount in the appendfile transport. If a
2520 filecount value is greater than 2G or if a quota value is greater than 2G
2521 on a system where the size of off_t is not greater than 4, a panic error
2522 is given.

1688f43b
PH
2524PH/23 When a malformed item such as 1.2.3/24 appears in a host list, it can
2525 never match. The debug and -bh output now contains an explicit error
2526 message indicating a malformed IPv4 address or mask.
2527
2528PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
2529 1.2.3.4 without a mask. Now it is not recognized as an IP address, and
2530 PH/23 above applies.

2540 that did not have a forward lookup, an error message of the form "no IP
2541 address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
2542 could be logged. Now it outputs the IP address instead of "NULL".

PH
2571PH/35 Change the default for dns_check_names_pattern to allow slashes within

2580 same order.

PH
2605PH/42 The content-scanning code uses fopen() to create files in which to put
2606 message data. Previously it was not paying any attention to the mode of
2607 the files. Exim runs with umask(0) because the rest of the code creates
2608 files with open(), and sets the required mode explicitly. Thus, these
2609 files were ending up world-writeable. This was not a big issue, because,
2610 being within the spool directory, they were not world-accessible. I have
2611 created a function called modefopen, which takes an additional mode
2612 argument. It sets umask(777), creates the file, chmods it to the required
2613 mode, then resets the umask. All the relevant calls to fopen() in the
2614 content scanning code have been changed to use this function.

PH
2622PH/45 When the plaintext authenticator is running as a client, the server's
2623 challenges are checked to ensure they are valid base64 strings. By
2624 default, the authentication attempt is cancelled if an invalid string is
2625 received. Setting client_ignore_invalid_base64 true ignores these errors.
2626 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2627 they are received. Thus, the responses can be made to depend on the
2628 challenges. If an invalid string is ignored, an empty string is placed in
2629 the variable.

PH
2649PH/52 Two bugs concerned with error handling when the smtp transport is
2650 used in LMTP mode:
2651
2652 (i) Exim was not creating retry information for temporary errors given
2653 for individual recipients after the DATA command when the smtp transport
2654 was used in LMTP mode. This meant that they could be retried too
2655 frequently, and not timed out correctly.
2656
2657 (ii) Exim was setting the flag that allows error details to be returned
2658 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2659 recipients that were returned after the DATA command.
2660
2661PH/53 This is related to PH/52, but is more general: for any failing address,
2662 when detailed error information was permitted to be returned to the
2663 sender, but the error was temporary, then after the final timeout, only
2664 "retry timeout exceeded" was returned. Now it returns the full error as
2665 well as "retry timeout exceeded".

2735PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2736 function verify_get_ident() calls ip_connect() to connect a socket, but
2737 if the "connect()" function timed out, ip_connect() used to close the
2738 socket. However, verify_get_ident() also closes the socket later, and in
2739 between Exim writes to the log, which may get opened at this point. When
2740 the socket was closed in ip_connect(), the log could get the same file
2741 descriptor number as the socket. This naturally causes chaos. The fix is
2742 not to close the socket in ip_connect(); the socket should be closed by
2743 the function that creates it. There was only one place in the code where
2744 this was missing, in the iplookup router, which I don't think anybody now
2745 uses, but I've fixed it anyway.

2764PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2765
2766 (1) Generate an error if the third argument for the ${prvs expansion is
2767 not a single digit.
2768
2769 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2770 string.
2771
2772 (3) Reset the variables that are obtained from the first argument of
2773 ${prvscheck and used in the second argument before leaving the code,
2774 because their memory is reclaimed, so using them afterwards may do
2775 silly things.
2776
2777 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2778 one (it's much easier than Tom thought :-).
2779
2780 (5) Because of (4), we can now allow for the use of $prvscheck_result
2781 inside the third argument.

2796 may be more than one such address. If so, they are comma-separated, like

2801PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2802 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2803 not being looked up in the rDNS to get a host name, Exim was showing the
2804 IP address twice in Received: lines, even though the IP addresses were
2805 identical. For example:
2806
2807 Received: from [1.2.3.4] (helo=[1.2.3.4])
2808
2809 However, if the real host name was known, it was omitting the HELO data
2810 if it matched the actual IP address. This has been tidied up so that it
2811 doesn't show the same IP address twice.

2837PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2839
2840 Auto-submitted: auto-generated
2841
2842 in the messages that it generates (bounce messages and others, such as
2843 warnings). In the case of bounce messages for non-SMTP mesages, there was
2844 also a typo: it was using "Auto_submitted" (underscore instead of
2845 hyphen). Since every message generated by Exim is necessarily in response
2846 to another message, thes have all been changed to:
2847
2848 Auto-Submitted: auto-replied
2849
2850 in accordance with these statements in the RFC:
2851
2852 The auto-replied keyword:
2853
2854 - SHOULD be used on messages sent in direct response to another
2855 message by an automatic process,
2856
2857 - MUST NOT be used on manually-generated messages,
2858
2859 - MAY be used on Delivery Status Notifications (DSNs) and Message
2860 Disposition Notifications (MDNs),

2900PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2901 canonical form (as documented). However, after a host name lookup from
2902 the IP address, check_host() was doing a simple string comparison with
2903 addresses acquired from the DNS when checking that the found name did
2904 have the original IP as one of its addresses. Since any found IPv6
2905 addresses are likely to be in abbreviated form, the comparison could
2906 fail. Luckily, there already exists a function for doing the comparison
2907 by converting both addresses to binary, so now that is used instead of
2908 the text comparison.

3182PH/03 The warning log line about a condition test deferring for a "warn" verb
3183 was being output only once per connection, rather than after each

PH
3205PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3206 with the definition in sysexits.h (which is #included earlier).
3207 Fortunately, Exim does not actually use EX_OK. The code used to try to
3208 preserve the sysexits.h value, by assumimg that macro definitions were
3209 scanned for macro replacements. I have been disabused of this notion,
3210 so now the code just undefines EX_OK before #including unistd.h.

PH
3212PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3213 in the smtp transport. When a block could not be written in a single
3214 write() function, the timeout was being re-applied to each part-write.
3215 This seems wrong - if the receiver was accepting one byte at a time it
3216 would take for ever. The timeout is now adjusted when this happens. It
3217 doesn't have to be particularly precise.

3283PH/15 The code I had for printing potentially long long variables in PH/11

3286 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3287 to be "long long int" or "long int". This is needed for the internal
3288 formatting function string_vformat().

3290PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3291 the configuration file to be ":syslog", then the script "guesses" where
3292 the logs files are, rather than using the compiled in default. In our
3293 case the guess is not the same as the compiled default, so the script
3294 suddenly stopped working when I started to use syslog. The patch checks
3295 to see if log_file_path is "". If so, it attempts to read it from exim
3296 with no configuration file to get the compiled in version, before it
3297 falls back to the previous guessing code."

3312 patch removes a few documentation additions to RFC 3028, because the

3314 and a new error check for 8bit text in MIME parts. Comparator and
