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.

23JH/03 The smtp transport now requests PRDR by default, if the server offers
24 it.
25
01a4a5c5 26JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 27 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
28 can be used to disable this per-host. The build option
29 EXPERIMENTAL_CERTNAMES is withdrawn.
30
cb1d7830 31JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 32 default to the word "system" to access the system default CA bundle.

JH
33 For GnuTLS, only version 3.0.20 or later.
34
610ff438 35JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19

36 (but not required) by default. The verification status is now logged by
37 default, for both outbound TLS and client-certificate supplying inbound
38 TLS connections
610ff438 39

JH
40JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
41 sites use this now.
42
50dc7409
JH
43JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
44 Status Notification (bounce) messages are now MIME format per RFC 3464.
45 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
46 under the control of the dsn_advertise_hosts option, and routers may

dc7b3d36 68 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
69 modifiers per server. Patch originally by <rommer@active.by>.
70
71JH/16 The spamd_address main option now supports a mixed list of local

JH
110JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
111 Normally benign, it bites when the pair was led to by a CNAME;
112 modern usage is to not canoicalize the domain to a CNAME target
113 (and we were inconsistent anyway for A-only vs AAAA+A).

136Exim version 4.85
137-----------------
138TL/01 When running the test suite, the README says that variables such as
139 no_msglog_check are global and can be placed anywhere in a specific
140 test's script, however it was observed that placement needed to be near
141 the beginning for it to behave that way. Changed the runtest perl
142 script to read through the entire script once to detect and set these
143 variables, reset to the beginning of the script, and then run through
144 the script parsing/test process like normal.

146TL/02 The BSD's have an arc4random API. One of the functions to induce
147 adding randomness was arc4random_stir(), but it has been removed in

149 function when detected.

TL
154TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
155 syntax errors in an expansion can be treated as a string instead of
156 logging or causing an error, due to the internal use of bool_lax
157 instead of bool when processing it.

WB
171JH/05 Fix results-pipe from transport process. Several recipients, combined
172 with certificate use, exposed issues where response data items split
173 over buffer boundaries were not parsed properly. This eventually
174 resulted in duplicates being sent. This issue only became common enough
175 to notice due to the introduction of conection certificate information,
176 the item size being so much larger. Found and fixed by Wolfgang Breyha.
177
8bc732e8
JH
178JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed

JH
185JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
186 is EXPERIMENTAL_EVENT, the main-configuration and transport options
187 both become "event_action", the variables become $event_name, $event_data
aec45841 188 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
189 routers, transports and related events. The tls:cert event is now also
190 raised for inbound connections, if the main configuration event_action
191 option is defined.

246-----------------
247
248TF/01 Correctly close the server side of TLS when forking for delivery.
249
250 When a message was received over SMTP with TLS, Exim failed to clear up
251 the incoming connection properly after forking off the child process to
252 deliver the message. In some situations the subsequent outgoing
253 delivery connection happened to have the same fd number as the incoming
254 connection previously had. Exim would try to use TLS and fail, logging
255 a "Bad file descriptor" error.

501TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
502
503 When a queue runner is handling a message, Exim first routes the
504 recipient addresses, during which it prunes them based on the retry
505 hints database. After that it attempts to deliver the message to
506 any remaining recipients. It then updates the hints database using
507 the retry rules.
508
509 So if a recipient address works intermittently, it can get repeatedly
510 deferred at routing time. The retry hints record remains fresh so the
511 address never reaches the final cutoff time.
512
513 This is a fairly common occurrence when a user is bumping up against
514 their storage quota. Exim had some logic in its local delivery code
515 to deal with this. However it did not apply to per-recipient defers
516 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
517
1ddeb334
TF
518 This change adds a proper retry rule check during routing so that the
519 final cutoff time is checked against the message's age. We only do
520 this check if there is an address retry record and there is not a
521 domain retry record; this implies that previous attempts to handle
522 the address had the retry_use_local_parts option turned on. We use
523 this as an approximation for the destination being like a local
524 delivery, as in LMTP.
67bd1ab3
TF
525
526 I suspect this new check makes the old local delivery cutoff check
527 redundant, but I have not verified this so I left the code in place.

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

561JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
562 Server implementation by Todd Lyons, client by JH.
563 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
564 config variable "prdr_enable" controls whether the server
565 advertises the facility. If the client requests PRDR a new
566 acl_data_smtp_prdr ACL is called once for each recipient, after
567 the body content is received and before the acl_smtp_data ACL.
568 The client is controlled by bolth of: a hosts_try_prdr option
569 on the smtp transport, and the server advertisement.
570 Default client logging of deliveries and rejections involving
571 PRDR are flagged with the string "PRDR".

849TF/03 Make the exiwhat support code safe for signals. Previously Exim might
850 lock up or crash if it happened to be inside a call to libc when it
851 got a SIGUSR1 from exiwhat.
852
853 The SIGUSR1 handler appends the current process status to the process
854 log which is later printed by exiwhat. It used to use the general
855 purpose logging code to do this, but several functions it calls are
856 not safe for signals.
857
858 The new output code in the SIGUSR1 handler is specific to the process
859 log, and simple enough that it's easy to inspect for signal safety.
860 Removing some special cases also simplifies the general logging code.
861 Removing the spurious timestamps from the process log simplifies
862 exiwhat.

864TF/04 Improved ratelimit ACL condition.
865
866 The /noupdate option has been deprecated in favour of /readonly which
867 has clearer semantics. The /leaky, /strict, and /readonly update modes
868 are mutually exclusive. The update mode is no longer included in the
869 database key; it just determines when the database is updated. (This
870 means that when you upgrde Exim will forget old rate measurements.)
871
872 Exim now checks that the per_* options are used with an update mode that
873 makes sense for the current ACL. For example, when Exim is processing a
874 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
875 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
876 must specify per_mail/readonly. If you omit the update mode it defaults to
877 /leaky where that makes sense (as before) or /readonly where required.
878
879 The /noupdate option is now undocumented but still supported for
880 backwards compatibility. It is equivalent to /readonly except that in
881 ACLs where /readonly is required you may specify /leaky/noupdate or
882 /strict/noupdate which are treated the same as /readonly.
883
884 A useful new feature is the /count= option. This is a generalization
885 of the per_byte option, so that you can measure the throughput of other
886 aggregate values. For example, the per_byte option is now equivalent
887 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
888
889 The per_rcpt option has been generalized using the /count= mechanism
890 (though it's more complicated than the per_byte equivalence). When it is
891 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
892 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
893 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
894 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
895 Note that using per_rcpt with a non-readonly update mode in more than
896 one ACL will cause the recipients to be double-counted. (The per_mail
897 and per_byte options don't have this problem.)
898
899 The handling of very low rates has changed slightly. If the computed rate
900 is less than the event's count (usually one) then this event is the first
901 after a long gap. In this case the rate is set to the same as this event's
902 count, so that the first message of a spam run is counted properly.
903
904 The major new feature is a mechanism for counting the rate of unique
905 events. The new per_addr option counts the number of different
906 recipients that someone has sent messages to in the last time period. It
907 behaves like per_rcpt if all the recipient addresses are different, but
908 duplicate recipient addresses do not increase the measured rate. Like
909 the /count= option this is a general mechanism, so the per_addr option
910 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
911 example, measure the rate that a client uses different sender addresses
912 with the options per_mail/unique=$sender_address. There are further
913 details in the main documentation.

1483-----------------
1484
1485PH/01 Another patch from the Sieve maintainer.
1486
6a3bceb1
PH
1487PH/02 When an IPv6 address is converted to a string for single-key lookup
1488 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1489 dots are used instead of colons so that keys in lsearch files need not
1490 contain colons. This was done some time before quoting was made available
1491 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1492 (notated using the quote facility) so as to distinguish them from IPv4
1493 keys. This meant that lookups for IP addresses in host lists did not work
1494 for iplsearch lookups.
1495
1496 This has been fixed by arranging for IPv6 addresses to be expressed with
1497 colons if the lookup type is iplsearch. This is not incompatible, because
1498 previously such lookups could never work.
1499
1500 The situation is now rather anomolous, since one *can* have colons in
1501 ordinary lsearch keys. However, making the change in all cases is
1502 incompatible and would probably break a number of configurations.

MH
1507MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1508 conversion specification without a maximum field width, thereby enabling
1509 a rogue spamd server to cause a buffer overflow. While nobody in their
1510 right mind would setup Exim to query an untrusted spamd server, an
1511 attacker that gains access to a server running spamd could potentially
1512 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1517MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1518 a directory entry by the name of the lookup key. Previously, if a
1519 symlink pointed to a non-existing file or a file in a directory that
1520 Exim lacked permissions to read, a lookup for a key matching that
1521 symlink would fail. Now it is enough that a matching directory entry
1522 exists, symlink or not. (Bugzilla 503.)

1705PH/29 SMTP synchronization checks are implemented when a command is read -
1706 there is a check that no more input is waiting when there shouldn't be
1707 any. However, for some commands, a delay in an ACL can mean that it is
1708 some time before the response is written. In this time, more input might
1709 arrive, invalidly. So now there are extra checks after an ACL has run for
1710 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1711 pipelining has not been advertised.

1726 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1727 was a macro that became an assignment, so it seemed to work. This has

PH
1785 the response to the final '.' that terminates a message, but only in the
1786 case where the client has not sent further data following the '.'
1787 (unfortunately, this is allowed). However, in many cases there won't be
1788 any further data because there won't be any more messages to send. A call
1789 to select() can be used: if it shows that the input is "ready", there is
1790 either input waiting, or the socket has been closed. An attempt to read
1791 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1792 would have sent an OK response which the client would never have see.

1803PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1804 fixed by 4.65/MH/01 (is this a record?) are fixed:
1805
1806 (i) An empty string was always treated as zero by the numeric comparison
1807 operators. This behaviour has been restored.
1808
1809 (ii) It is documented that the numeric comparison operators always treat
1810 their arguments as decimal numbers. This was broken in that numbers
1811 starting with 0 were being interpreted as octal.
1812
1813 While fixing these problems I realized that there was another issue that
1814 hadn't been noticed. Values of message_size_limit (both the global option
1815 and the transport option) were treated as octal if they started with 0.
1816 The documentation was vague. These values are now always treated as
1817 decimal, and I will make that clear in the documentation.

1833 is held in a short int, deliveries were likely to be lost. As such a
1834 large number of recipients for a single message is ridiculous
1835 (performance will be very, very poor), I have chosen to impose a limit
1836 rather than extend the field.

2b1c6e3a
PH
1861PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1862 callout verification, Exim cached a "reject" for the entire domain. This
1863 is correct for most verifications, but it is not correct for a recipient
1864 verification with use_sender or use_postmaster set, because in that case
1865 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1866 case of MAIL FROM:<> rejection from other early rejections (e.g.
1867 rejection of HELO). When verifying a recipient using a non-null MAIL
1868 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1869 Whatever the result of the callout, the value of the domain cache is
1870 left unchanged (for any other kind of callout, getting as far as trying
1871 RCPT means that the domain itself is ok).

1905PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1907 probably the interface on which it is arriving) and not to the outgoing
1908 callout (which could be using a different interface). This has been
1909 changed to use the value of the helo_data option from the smtp transport
1910 instead - this is what is used when a message is actually being sent. If
1911 there is no remote transport (possible with a router that sets up host
1912 addresses), $smtp_active_hostname is used.

7befa435 1915 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1916 (a) The code assumed that strncpy() returns a negative number on buffer
1917 overflow, which isn't the case. Replaced with Exim's string_format()
1918 function.
1919 (b) There were several signed/unsigned issues. I just did the minimum
1920 hacking in of casts. There is scope for a larger refactoring.
1921 (c) The code used strcasecmp() which is not a standard C function.
1922 Replaced with Exim's strcmpic() function.
1923 (d) The code set only $1; it now sets $auth1 as well.
1924 (e) A simple test gave the error "authentication client didn't specify
1925 service in request". It would seem that Dovecot has changed its
1926 interface. Fortunately there's a specification; I followed it and
1927 changed what the client sends and it appears to be working now.

1934 -v the output is "A verified" because verification stops after a
1935 successful redirection if more than one address is generated. However,
1936 with -v the child addresses are also verified. Exim was outputting "A
1937 failed to verify" and then showing the successful verification for C,
1938 with its parentage. It now outputs "B failed to verify", showing B's
1939 parentage before showing the successful verification of C.

322050c2
PH
1945PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1946 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1947 they consult the DNS. I had assumed they would set it the way they
1948 wanted; and indeed my experiments on Linux seem to show that in some
1949 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1950 To be on the safe side, however, I have now made the interface to
1951 host_find_byname() similar to host_find_bydns(), with an argument
1952 containing the DNS resolver options. The host_find_byname() function now
1953 sets these options at its start, just as host_find_bydns() does. The smtp
1954 transport options dns_qualify_single and dns_search_parents are passed to
1955 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1956 of host_find_byname() use the default settings of RES_DEFNAMES

PH
1959PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1960 spool_read_header() do less string testing, by means of a preliminary
1961 switch on the second character of optional "-foo" lines. (This is
1962 overdue, caused by the large number of possibilities that now exist.
1963 Originally there were few.) While I was there, I also converted the
1964 str(n)cmp tests so they don't re-test the leading "-" and the first
1965 character, in the hope this might squeeze out yet more improvement.

PH
1967PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1968 flag allowing group syntax was set by the header_syntax check but not
1969 turned off, possible causing trouble later; (2) The flag was not being
1970 set at all for the header_verify test, causing "group"-style headers to
1971 be rejected. I have now set it in this case, and also caused header_
1972 verify to ignore an empty address taken from a group. While doing this, I
1973 came across some other cases where the code for allowing group syntax
1974 while scanning a header line wasn't quite right (mostly, not resetting
1975 the flag correctly in the right place). These bugs could have caused
1976 trouble for malformed header lines. I hope it is now all correct.

1978PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1979 with the "reply" argument non-NULL. The code, however (which originally
1980 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1981 but it didn't always do it. This confused somebody who was copying the
1982 code for some other use. I have removed all the tests.

PH
1984PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1985 feature that was used to support insecure browsers during the U.S. crypto
1986 embargo. It requires special client support, and Exim is probably the
1987 only MTA that supported it -- and would never use it because real RSA is
1988 always available. This code has been removed, because it had the bad
1989 effect of slowing Exim down by computing (never used) parameters for the
1990 RSA_EXPORT functionality.

1992PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1995 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1996 if the connection is using TLS or if the remote IP is the same as the
1997 local IP, and the "valid-client-cert option" if a client certificate has
1998 been verified.

2029
2030PH/30 Exim was sometimes attempting to deliver messages that had suffered
2031 address errors (4xx response to RCPT) over the same connection as other
2032 messages routed to the same hosts. Such deliveries are always "forced",
2033 so retry times are not inspected. This resulted in far too many retries
2034 for the affected addresses. The effect occurred only when there were more
2035 hosts than the hosts_max_try setting in the smtp transport when it had
2036 the 4xx errors. Those hosts that it had tried were not added to the list
2037 of hosts for which the message was waiting, so if all were tried, there
2038 was no problem. Two fixes have been applied:
2039
2040 (i) If there are any address or message errors in an SMTP delivery, none
2041 of the hosts (tried or untried) are now added to the list of hosts
2042 for which the message is waiting, so the message should not be a
2043 candidate for sending over the same connection that was used for a
2044 successful delivery of some other message. This seems entirely
2045 reasonable: after all the message is NOT "waiting for some host".
2046 This is so "obvious" that I'm not sure why it wasn't done
2047 previously. Hope I haven't missed anything, but it can't do any
2048 harm, as the worst effect is to miss an optimization.
2049
2050 (ii) If, despite (i), such a delivery is accidentally attempted, the
2051 routing retry time is respected, so at least it doesn't keep
2052 hammering the server.

2067PH/35 The error "getsockname() failed: connection reset by peer" was being
2068 written to the panic log as well as the main log, but it isn't really
2069 panic-worthy as it just means the connection died rather early on. I have
2070 removed the panic log writing for the ECONNRESET error when getsockname()
2071 fails.
2072
48c7f9e2
PH
2073PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2074 runs only) independently of the message's sender address. This meant
2075 that, if the 4xx error was in fact related to the sender, a different
2076 message to the same recipient with a different sender could confuse
2077 things. In particualar, this can happen when sending to a greylisting
2078 server, but other circumstances could also provoke similar problems.
2079 I have changed the default so that the retry time for these errors is now
2080 based a combination of the sender and recipient addresses. This change
2081 can be overridden by setting address_retry_include_sender=false in the
2082 smtp transport.

2350PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2351 "Deny" causes Exim to reject the incoming connection with a 554 error.
2352 Unfortunately, if there is a major crisis, such as a disk failure,
2353 tcp-wrappers gives "deny", whereas what one would like would be some
2354 kind of temporary error. A kludge has been added to help with this.
2355 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2356 554 error is used if errno is still zero or contains ENOENT (which occurs
2357 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2358 451 error is used.

2380PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

2383 used only to exclude .Trash (or whatever) when the size of the mailbox
2384 was calculated. There was no check that a delivery was happening into an

2394PH/01 The code for finding all the local interface addresses on a FreeBSD
2395 system running IPv6 was broken. This may well have applied to all BSD
2396 systems, as well as to others that have similar system calls. The broken
2397 code found IPv4 interfaces correctly, but gave incorrect values for the
2398 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2399 that it would not match correctly against @[] and not recognize the IPv6
2400 addresses as local.

2443 autoreply, Exim could try to deliver to a non-existent relative file

2466 (a) Failures to set uid/gid, the current directory, or a process leader
2467 in a subprocess such as that created by queryprogram now generate
2468 suitable debugging ouput when -d is set.

2478 additional section of a DNS packet that returns MX or SRV records.
2479 Instead, it always explicitly searches for A/AAAA records. This avoids
2480 major problems that occur when a DNS server includes only records of one
2481 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2482 fixed another bug: if SRV records were looked up and the corresponding
2483 address records were *not* found in the additional section, the port
2484 values from the SRV records were lost.

PH
2494PH/19 When calculating a retry time, Exim used to measure the "time since
2495 failure" by looking at the "first failed" field in the retry record. Now
2496 it does not use this if it is later than than the arrival time of the
2497 message. Instead it uses the arrival time. This makes for better
2498 behaviour in cases where some deliveries succeed, thus re-setting the
2499 "first failed" field. An example is a quota failure for a huge message
2500 when small messages continue to be delivered. Without this change, the
2501 "time since failure" will always be short, possible causing more frequent
2502 delivery attempts for the huge message than are intended.

2599PH/42 The content-scanning code uses fopen() to create files in which to put
2600 message data. Previously it was not paying any attention to the mode of

2602 files with open(), and sets the required mode explicitly. Thus, these
2603 files were ending up world-writeable. This was not a big issue, because,
2604 being within the spool directory, they were not world-accessible. I have
2605 created a function called modefopen, which takes an additional mode
2606 argument. It sets umask(777), creates the file, chmods it to the required
2607 mode, then resets the umask. All the relevant calls to fopen() in the

2645
2646 (i) Exim was not creating retry information for temporary errors given

2648 was used in LMTP mode. This meant that they could be retried too
2649 frequently, and not timed out correctly.
2650
2651 (ii) Exim was setting the flag that allows error details to be returned
2652 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2653 recipients that were returned after the DATA command.
2654
2655PH/53 This is related to PH/52, but is more general: for any failing address,
2656 when detailed error information was permitted to be returned to the

2732 socket. However, verify_get_ident() also closes the socket later, and in
2733 between Exim writes to the log, which may get opened at this point. When
2734 the socket was closed in ip_connect(), the log could get the same file
2735 descriptor number as the socket. This naturally causes chaos. The fix is
2736 not to close the socket in ip_connect(); the socket should be closed by
2737 the function that creates it. There was only one place in the code where
2738 this was missing, in the iplookup router, which I don't think anybody now
2739 uses, but I've fixed it anyway.

2758PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2759
2760 (1) Generate an error if the third argument for the ${prvs expansion is
2761 not a single digit.
2762
2763 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2764 string.
2765
2766 (3) Reset the variables that are obtained from the first argument of
2767 ${prvscheck and used in the second argument before leaving the code,
2768 because their memory is reclaimed, so using them afterwards may do
2769 silly things.
2770
2771 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2772 one (it's much easier than Tom thought :-).
2773
2774 (5) Because of (4), we can now allow for the use of $prvscheck_result
2775 inside the third argument.

2786
2787 => >A.N.Other <ano@some.domain> <original@ddress> ...
2788
2789 This has been changed so that it extracts the operative address. There
2790 may be more than one such address. If so, they are comma-separated, like

2795PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2796 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2797 not being looked up in the rDNS to get a host name, Exim was showing the
2798 IP address twice in Received: lines, even though the IP addresses were
2799 identical. For example:
2800
2801 Received: from [1.2.3.4] (helo=[1.2.3.4])
2802
2803 However, if the real host name was known, it was omitting the HELO data
2804 if it matched the actual IP address. This has been tidied up so that it
2805 doesn't show the same IP address twice.

2831PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2833
2834 Auto-submitted: auto-generated
2835
2836 in the messages that it generates (bounce messages and others, such as
2837 warnings). In the case of bounce messages for non-SMTP mesages, there was
2838 also a typo: it was using "Auto_submitted" (underscore instead of
2839 hyphen). Since every message generated by Exim is necessarily in response
2840 to another message, thes have all been changed to:
2841
2842 Auto-Submitted: auto-replied
2843
2844 in accordance with these statements in the RFC:
2845
2846 The auto-replied keyword:
2847
2848 - SHOULD be used on messages sent in direct response to another
2849 message by an automatic process,
2850
2851 - MUST NOT be used on manually-generated messages,

2854 Disposition Notifications (MDNs),

2894PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2895 canonical form (as documented). However, after a host name lookup from
2896 the IP address, check_host() was doing a simple string comparison with
2897 addresses acquired from the DNS when checking that the found name did
2898 have the original IP as one of its addresses. Since any found IPv6
2899 addresses are likely to be in abbreviated form, the comparison could
2900 fail. Luckily, there already exists a function for doing the comparison
2901 by converting both addresses to binary, so now that is used instead of
2902 the text comparison.

3148TF/07 Exim produced the error message "an SRV record indicated no SMTP

3166PH/01 When a transport filter timed out in a pipe delivery, and the pipe

3168 filter timeout was being overwritten with the pipe command error. Now the
3169 underlying error message should be appended to the second error message.

3176PH/03 The warning log line about a condition test deferring for a "warn" verb
3177 was being output only once per connection, rather than after each

3179 "warn" verbs). This seems wrong, so I have changed it.

3181TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3182 it should not have, which might have caused a crash in the right
3183 circumstances, but probably never did.

3185PH/04 Installed a modified version of Tony Finch's patch to make submission

PH
3199PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3200 with the definition in sysexits.h (which is #included earlier).
3201 Fortunately, Exim does not actually use EX_OK. The code used to try to
3202 preserve the sysexits.h value, by assumimg that macro definitions were
3203 scanned for macro replacements. I have been disabused of this notion,
3204 so now the code just undefines EX_OK before #including unistd.h.

PH
3206PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3207 in the smtp transport. When a block could not be written in a single
3208 write() function, the timeout was being re-applied to each part-write.
3209 This seems wrong - if the receiver was accepting one byte at a time it
3210 would take for ever. The timeout is now adjusted when this happens. It
3211 doesn't have to be particularly precise.

3280 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3281 to be "long long int" or "long int". This is needed for the internal
3282 formatting function string_vformat().

3284PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3285 the configuration file to be ":syslog", then the script "guesses" where
3286 the logs files are, rather than using the compiled in default. In our
3287 case the guess is not the same as the compiled default, so the script
3288 suddenly stopped working when I started to use syslog. The patch checks
3289 to see if log_file_path is "". If so, it attempts to read it from exim
3290 with no configuration file to get the compiled in version, before it
3291 falls back to the previous guessing code."

3305PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3306 patch removes a few documentation additions to RFC 3028, because the

3308 and a new error check for 8bit text in MIME parts. Comparator and
3309 require names are now matched exactly. I enabled the subaddress
3310 extension, but it is not well tested yet (read: it works for me)."
