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.

21 it.
22
01a4a5c5 23JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 24 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
25 can be used to disable this per-host. The build option
26 EXPERIMENTAL_CERTNAMES is withdrawn.
27

R
66 modifiers per server. Patch originally by <rommer@active.by>.
67

JH
107JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
108 Normally benign, it bites when the pair was led to by a CNAME;
109 modern usage is to not canoicalize the domain to a CNAME target
110 (and we were inconsistent anyway for A-only vs AAAA+A).

133Exim version 4.85
134-----------------
135TL/01 When running the test suite, the README says that variables such as
136 no_msglog_check are global and can be placed anywhere in a specific
137 test's script, however it was observed that placement needed to be near
138 the beginning for it to behave that way. Changed the runtest perl
139 script to read through the entire script once to detect and set these
140 variables, reset to the beginning of the script, and then run through
141 the script parsing/test process like normal.
142
ac20058f
TL
143TL/02 The BSD's have an arc4random API. One of the functions to induce
144 adding randomness was arc4random_stir(), but it has been removed in
145 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
146 function when detected.
147
a9b8ec8b
JH
148JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
149 cause callback expansion.
150
6286d7c4
TL
151TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
152 syntax errors in an expansion can be treated as a string instead of
153 logging or causing an error, due to the internal use of bool_lax
154 instead of bool when processing it.
155
0f06b4f2 156JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d

WB
168JH/05 Fix results-pipe from transport process. Several recipients, combined
169 with certificate use, exposed issues where response data items split
170 over buffer boundaries were not parsed properly. This eventually
171 resulted in duplicates being sent. This issue only became common enough
172 to notice due to the introduction of conection certificate information,
173 the item size being so much larger. Found and fixed by Wolfgang Breyha.
174
8bc732e8
JH
175JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
176 size buffer was used, resulting in syntax errors when an expansion
177 exceeded it.

179JH/07 Add support for directories of certificates when compiled with a GnuTLS
180 version 3.3.6 or later.
181
774ef2d7
JH
182JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
183 is EXPERIMENTAL_EVENT, the main-configuration and transport options
184 both become "event_action", the variables become $event_name, $event_data
aec45841 185 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
186 routers, transports and related events. The tls:cert event is now also
187 raised for inbound connections, if the main configuration event_action
188 option is defined.

243-----------------
244
245TF/01 Correctly close the server side of TLS when forking for delivery.
246
247 When a message was received over SMTP with TLS, Exim failed to clear up
248 the incoming connection properly after forking off the child process to
249 deliver the message. In some situations the subsequent outgoing
250 delivery connection happened to have the same fd number as the incoming
251 connection previously had. Exim would try to use TLS and fail, logging
252 a "Bad file descriptor" error.

498TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
499
500 When a queue runner is handling a message, Exim first routes the
501 recipient addresses, during which it prunes them based on the retry
502 hints database. After that it attempts to deliver the message to
503 any remaining recipients. It then updates the hints database using
504 the retry rules.
505
506 So if a recipient address works intermittently, it can get repeatedly
507 deferred at routing time. The retry hints record remains fresh so the
508 address never reaches the final cutoff time.
509
510 This is a fairly common occurrence when a user is bumping up against
511 their storage quota. Exim had some logic in its local delivery code
512 to deal with this. However it did not apply to per-recipient defers
513 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
514
1ddeb334
TF
515 This change adds a proper retry rule check during routing so that the
516 final cutoff time is checked against the message's age. We only do
517 this check if there is an address retry record and there is not a
518 domain retry record; this implies that previous attempts to handle
519 the address had the retry_use_local_parts option turned on. We use
520 this as an approximation for the destination being like a local
521 delivery, as in LMTP.
67bd1ab3
TF
522
523 I suspect this new check makes the old local delivery cutoff check
524 redundant, but I have not verified this so I left the code in place.

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

559 Server implementation by Todd Lyons, client by JH.
560 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
561 config variable "prdr_enable" controls whether the server
562 advertises the facility. If the client requests PRDR a new
563 acl_data_smtp_prdr ACL is called once for each recipient, after
564 the body content is received and before the acl_smtp_data ACL.
565 The client is controlled by bolth of: a hosts_try_prdr option
566 on the smtp transport, and the server advertisement.
567 Default client logging of deliveries and rejections involving
568 PRDR are flagged with the string "PRDR".

846TF/03 Make the exiwhat support code safe for signals. Previously Exim might
847 lock up or crash if it happened to be inside a call to libc when it
848 got a SIGUSR1 from exiwhat.
849
850 The SIGUSR1 handler appends the current process status to the process
851 log which is later printed by exiwhat. It used to use the general
852 purpose logging code to do this, but several functions it calls are
853 not safe for signals.
854
855 The new output code in the SIGUSR1 handler is specific to the process
856 log, and simple enough that it's easy to inspect for signal safety.
857 Removing some special cases also simplifies the general logging code.
858 Removing the spurious timestamps from the process log simplifies
859 exiwhat.

861TF/04 Improved ratelimit ACL condition.
862
863 The /noupdate option has been deprecated in favour of /readonly which
864 has clearer semantics. The /leaky, /strict, and /readonly update modes
865 are mutually exclusive. The update mode is no longer included in the
866 database key; it just determines when the database is updated. (This
867 means that when you upgrde Exim will forget old rate measurements.)
868
869 Exim now checks that the per_* options are used with an update mode that
870 makes sense for the current ACL. For example, when Exim is processing a
871 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
872 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
873 must specify per_mail/readonly. If you omit the update mode it defaults to
874 /leaky where that makes sense (as before) or /readonly where required.
875
876 The /noupdate option is now undocumented but still supported for
877 backwards compatibility. It is equivalent to /readonly except that in
878 ACLs where /readonly is required you may specify /leaky/noupdate or
879 /strict/noupdate which are treated the same as /readonly.
880
881 A useful new feature is the /count= option. This is a generalization
882 of the per_byte option, so that you can measure the throughput of other
883 aggregate values. For example, the per_byte option is now equivalent
884 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
885
886 The per_rcpt option has been generalized using the /count= mechanism
887 (though it's more complicated than the per_byte equivalence). When it is
888 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
889 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
890 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
891 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
892 Note that using per_rcpt with a non-readonly update mode in more than
893 one ACL will cause the recipients to be double-counted. (The per_mail
894 and per_byte options don't have this problem.)
895
896 The handling of very low rates has changed slightly. If the computed rate
897 is less than the event's count (usually one) then this event is the first
898 after a long gap. In this case the rate is set to the same as this event's
899 count, so that the first message of a spam run is counted properly.
900
901 The major new feature is a mechanism for counting the rate of unique
902 events. The new per_addr option counts the number of different
903 recipients that someone has sent messages to in the last time period. It
904 behaves like per_rcpt if all the recipient addresses are different, but
905 duplicate recipient addresses do not increase the measured rate. Like
906 the /count= option this is a general mechanism, so the per_addr option
907 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
908 example, measure the rate that a client uses different sender addresses
909 with the options per_mail/unique=$sender_address. There are further
910 details in the main documentation.

1480-----------------
1481
1482PH/01 Another patch from the Sieve maintainer.
1483
6a3bceb1
PH
1484PH/02 When an IPv6 address is converted to a string for single-key lookup
1485 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1486 dots are used instead of colons so that keys in lsearch files need not
1487 contain colons. This was done some time before quoting was made available
1488 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1489 (notated using the quote facility) so as to distinguish them from IPv4
1490 keys. This meant that lookups for IP addresses in host lists did not work
1491 for iplsearch lookups.
1492
1493 This has been fixed by arranging for IPv6 addresses to be expressed with
1494 colons if the lookup type is iplsearch. This is not incompatible, because
1495 previously such lookups could never work.
1496
1497 The situation is now rather anomolous, since one *can* have colons in
1498 ordinary lsearch keys. However, making the change in all cases is
1499 incompatible and would probably break a number of configurations.

MH
1504MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1505 conversion specification without a maximum field width, thereby enabling
1506 a rogue spamd server to cause a buffer overflow. While nobody in their
1507 right mind would setup Exim to query an untrusted spamd server, an
1508 attacker that gains access to a server running spamd could potentially
1509 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1514MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1515 a directory entry by the name of the lookup key. Previously, if a
1516 symlink pointed to a non-existing file or a file in a directory that
1517 Exim lacked permissions to read, a lookup for a key matching that
1518 symlink would fail. Now it is enough that a matching directory entry
1519 exists, symlink or not. (Bugzilla 503.)

PH
1702PH/29 SMTP synchronization checks are implemented when a command is read -
1703 there is a check that no more input is waiting when there shouldn't be
1704 any. However, for some commands, a delay in an ACL can mean that it is
1705 some time before the response is written. In this time, more input might
1706 arrive, invalidly. So now there are extra checks after an ACL has run for
1707 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1708 pipelining has not been advertised.

1723 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1724 was a macro that became an assignment, so it seemed to work. This has

1764 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1782 the response to the final '.' that terminates a message, but only in the
1783 case where the client has not sent further data following the '.'
1784 (unfortunately, this is allowed). However, in many cases there won't be
1785 any further data because there won't be any more messages to send. A call
1786 to select() can be used: if it shows that the input is "ready", there is
1787 either input waiting, or the socket has been closed. An attempt to read
1788 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1789 would have sent an OK response which the client would never have see.

1800PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1801 fixed by 4.65/MH/01 (is this a record?) are fixed:
1802
1803 (i) An empty string was always treated as zero by the numeric comparison
1804 operators. This behaviour has been restored.
1805
1806 (ii) It is documented that the numeric comparison operators always treat
1807 their arguments as decimal numbers. This was broken in that numbers
1808 starting with 0 were being interpreted as octal.
1809
1810 While fixing these problems I realized that there was another issue that
1811 hadn't been noticed. Values of message_size_limit (both the global option
1812 and the transport option) were treated as octal if they started with 0.
1813 The documentation was vague. These values are now always treated as
1814 decimal, and I will make that clear in the documentation.

1830 is held in a short int, deliveries were likely to be lost. As such a
1831 large number of recipients for a single message is ridiculous
1832 (performance will be very, very poor), I have chosen to impose a limit
1833 rather than extend the field.

1839TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1840 leftover -K file (the existence of which was triggered by #402).

1848
1849TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1858PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1859 callout verification, Exim cached a "reject" for the entire domain. This
1860 is correct for most verifications, but it is not correct for a recipient
1861 verification with use_sender or use_postmaster set, because in that case
1862 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1863 case of MAIL FROM:<> rejection from other early rejections (e.g.
1864 rejection of HELO). When verifying a recipient using a non-null MAIL
1865 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1866 Whatever the result of the callout, the value of the domain cache is
1867 left unchanged (for any other kind of callout, getting as far as trying
1868 RCPT means that the domain itself is ok).

1902PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1904 probably the interface on which it is arriving) and not to the outgoing
1905 callout (which could be using a different interface). This has been
1906 changed to use the value of the helo_data option from the smtp transport
1907 instead - this is what is used when a message is actually being sent. If
1908 there is no remote transport (possible with a router that sets up host
1909 addresses), $smtp_active_hostname is used.

7befa435 1912 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1913 (a) The code assumed that strncpy() returns a negative number on buffer
1914 overflow, which isn't the case. Replaced with Exim's string_format()
1915 function.
1916 (b) There were several signed/unsigned issues. I just did the minimum
1917 hacking in of casts. There is scope for a larger refactoring.
1918 (c) The code used strcasecmp() which is not a standard C function.
1919 Replaced with Exim's strcmpic() function.
1920 (d) The code set only $1; it now sets $auth1 as well.
1921 (e) A simple test gave the error "authentication client didn't specify
1922 service in request". It would seem that Dovecot has changed its
1923 interface. Fortunately there's a specification; I followed it and
1924 changed what the client sends and it appears to be working now.

1930 address A is aliased to B and C, where B exists and C does not. Without
1931 -v the output is "A verified" because verification stops after a
1932 successful redirection if more than one address is generated. However,
1933 with -v the child addresses are also verified. Exim was outputting "A
1934 failed to verify" and then showing the successful verification for C,
1935 with its parentage. It now outputs "B failed to verify", showing B's
1936 parentage before showing the successful verification of C.

PH
1942PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1943 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1944 they consult the DNS. I had assumed they would set it the way they
1945 wanted; and indeed my experiments on Linux seem to show that in some
1946 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1947 To be on the safe side, however, I have now made the interface to
1948 host_find_byname() similar to host_find_bydns(), with an argument
1949 containing the DNS resolver options. The host_find_byname() function now
1950 sets these options at its start, just as host_find_bydns() does. The smtp
1951 transport options dns_qualify_single and dns_search_parents are passed to
1952 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1953 of host_find_byname() use the default settings of RES_DEFNAMES
1954 (qualify_single) but not RES_DNSRCH (search_parents).

1956PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1957 spool_read_header() do less string testing, by means of a preliminary
1958 switch on the second character of optional "-foo" lines. (This is
1959 overdue, caused by the large number of possibilities that now exist.
1960 Originally there were few.) While I was there, I also converted the
1961 str(n)cmp tests so they don't re-test the leading "-" and the first
1962 character, in the hope this might squeeze out yet more improvement.

1964PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1965 flag allowing group syntax was set by the header_syntax check but not
1966 turned off, possible causing trouble later; (2) The flag was not being
1967 set at all for the header_verify test, causing "group"-style headers to
1968 be rejected. I have now set it in this case, and also caused header_
1969 verify to ignore an empty address taken from a group. While doing this, I
1970 came across some other cases where the code for allowing group syntax
1971 while scanning a header line wasn't quite right (mostly, not resetting
1972 the flag correctly in the right place). These bugs could have caused
1973 trouble for malformed header lines. I hope it is now all correct.

1975PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1976 with the "reply" argument non-NULL. The code, however (which originally
1977 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1978 but it didn't always do it. This confused somebody who was copying the
1979 code for some other use. I have removed all the tests.

PH
1981PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1982 feature that was used to support insecure browsers during the U.S. crypto
1983 embargo. It requires special client support, and Exim is probably the
1984 only MTA that supported it -- and would never use it because real RSA is
1985 always available. This code has been removed, because it had the bad
1986 effect of slowing Exim down by computing (never used) parameters for the
1987 RSA_EXPORT functionality.

1989PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1990 authenticator to fail if there's a tab character in the incoming data

1992 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1993 if the connection is using TLS or if the remote IP is the same as the
1994 local IP, and the "valid-client-cert option" if a client certificate has
1995 been verified.

2027PH/30 Exim was sometimes attempting to deliver messages that had suffered
2028 address errors (4xx response to RCPT) over the same connection as other
2029 messages routed to the same hosts. Such deliveries are always "forced",
2030 so retry times are not inspected. This resulted in far too many retries
2031 for the affected addresses. The effect occurred only when there were more
2032 hosts than the hosts_max_try setting in the smtp transport when it had
2033 the 4xx errors. Those hosts that it had tried were not added to the list
2034 of hosts for which the message was waiting, so if all were tried, there
2035 was no problem. Two fixes have been applied:
2036
2037 (i) If there are any address or message errors in an SMTP delivery, none
2038 of the hosts (tried or untried) are now added to the list of hosts
2039 for which the message is waiting, so the message should not be a
2040 candidate for sending over the same connection that was used for a
2041 successful delivery of some other message. This seems entirely
2042 reasonable: after all the message is NOT "waiting for some host".
2043 This is so "obvious" that I'm not sure why it wasn't done
2044 previously. Hope I haven't missed anything, but it can't do any
2045 harm, as the worst effect is to miss an optimization.
2046
2047 (ii) If, despite (i), such a delivery is accidentally attempted, the
2048 routing retry time is respected, so at least it doesn't keep
2049 hammering the server.

2064PH/35 The error "getsockname() failed: connection reset by peer" was being
2065 written to the panic log as well as the main log, but it isn't really
2066 panic-worthy as it just means the connection died rather early on. I have
2067 removed the panic log writing for the ECONNRESET error when getsockname()
2068 fails.
2069
48c7f9e2
PH
2070PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2071 runs only) independently of the message's sender address. This meant
2072 that, if the 4xx error was in fact related to the sender, a different
2073 message to the same recipient with a different sender could confuse
2074 things. In particualar, this can happen when sending to a greylisting
2075 server, but other circumstances could also provoke similar problems.
2076 I have changed the default so that the retry time for these errors is now
2077 based a combination of the sender and recipient addresses. This change
2078 can be overridden by setting address_retry_include_sender=false in the
2079 smtp transport.

2347PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2348 "Deny" causes Exim to reject the incoming connection with a 554 error.
2349 Unfortunately, if there is a major crisis, such as a disk failure,
2350 tcp-wrappers gives "deny", whereas what one would like would be some
2351 kind of temporary error. A kludge has been added to help with this.
2352 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2353 554 error is used if errno is still zero or contains ENOENT (which occurs
2354 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2355 451 error is used.

2377PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

2380 used only to exclude .Trash (or whatever) when the size of the mailbox
2381 was calculated. There was no check that a delivery was happening into an

2391PH/01 The code for finding all the local interface addresses on a FreeBSD
2392 system running IPv6 was broken. This may well have applied to all BSD
2393 systems, as well as to others that have similar system calls. The broken
2394 code found IPv4 interfaces correctly, but gave incorrect values for the
2395 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2396 that it would not match correctly against @[] and not recognize the IPv6
2397 addresses as local.

2440 autoreply, Exim could try to deliver to a non-existent relative file

2464 in a subprocess such as that created by queryprogram now generate
2465 suitable debugging ouput when -d is set.

2475 additional section of a DNS packet that returns MX or SRV records.
2476 Instead, it always explicitly searches for A/AAAA records. This avoids
2477 major problems that occur when a DNS server includes only records of one
2478 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2479 fixed another bug: if SRV records were looked up and the corresponding
2480 address records were *not* found in the additional section, the port
2481 values from the SRV records were lost.

PH
2491PH/19 When calculating a retry time, Exim used to measure the "time since
2492 failure" by looking at the "first failed" field in the retry record. Now
2493 it does not use this if it is later than than the arrival time of the
2494 message. Instead it uses the arrival time. This makes for better
2495 behaviour in cases where some deliveries succeed, thus re-setting the
2496 "first failed" field. An example is a quota failure for a huge message
2497 when small messages continue to be delivered. Without this change, the
2498 "time since failure" will always be short, possible causing more frequent
2499 delivery attempts for the huge message than are intended.

2596PH/42 The content-scanning code uses fopen() to create files in which to put
2597 message data. Previously it was not paying any attention to the mode of
2598 the files. Exim runs with umask(0) because the rest of the code creates
2599 files with open(), and sets the required mode explicitly. Thus, these
2600 files were ending up world-writeable. This was not a big issue, because,
2601 being within the spool directory, they were not world-accessible. I have
2602 created a function called modefopen, which takes an additional mode
2603 argument. It sets umask(777), creates the file, chmods it to the required
2604 mode, then resets the umask. All the relevant calls to fopen() in the

2645 was used in LMTP mode. This meant that they could be retried too
2646 frequently, and not timed out correctly.
2647
2648 (ii) Exim was setting the flag that allows error details to be returned
2649 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2650 recipients that were returned after the DATA command.
2651
2652PH/53 This is related to PH/52, but is more general: for any failing address,
2653 when detailed error information was permitted to be returned to the

2731 the socket was closed in ip_connect(), the log could get the same file
2732 descriptor number as the socket. This naturally causes chaos. The fix is
2733 not to close the socket in ip_connect(); the socket should be closed by
2734 the function that creates it. There was only one place in the code where
2735 this was missing, in the iplookup router, which I don't think anybody now
2736 uses, but I've fixed it anyway.

2755PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2756
2757 (1) Generate an error if the third argument for the ${prvs expansion is
2758 not a single digit.
2759
2760 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2761 string.
2762
2763 (3) Reset the variables that are obtained from the first argument of
2764 ${prvscheck and used in the second argument before leaving the code,
2765 because their memory is reclaimed, so using them afterwards may do
2766 silly things.
2767
2768 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2769 one (it's much easier than Tom thought :-).
2770
2771 (5) Because of (4), we can now allow for the use of $prvscheck_result
2772 inside the third argument.

2781PH/05 When a filter generated an autoreply, the entire To: header line was
2782 quoted in the delivery log line, like this:
2783
2784 => >A.N.Other <ano@some.domain> <original@ddress> ...
2785
2786 This has been changed so that it extracts the operative address. There
2787 may be more than one such address. If so, they are comma-separated, like
2788 this:

PH
2792PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2793 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2794 not being looked up in the rDNS to get a host name, Exim was showing the
2795 IP address twice in Received: lines, even though the IP addresses were
2796 identical. For example:
2797
2798 Received: from [1.2.3.4] (helo=[1.2.3.4])
2799
2800 However, if the real host name was known, it was omitting the HELO data
2801 if it matched the actual IP address. This has been tidied up so that it
2802 doesn't show the same IP address twice.

2828PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2830
2831 Auto-submitted: auto-generated
2832
2833 in the messages that it generates (bounce messages and others, such as
2834 warnings). In the case of bounce messages for non-SMTP mesages, there was
2835 also a typo: it was using "Auto_submitted" (underscore instead of
2836 hyphen). Since every message generated by Exim is necessarily in response
2837 to another message, thes have all been changed to:
2838
2839 Auto-Submitted: auto-replied
2840
2841 in accordance with these statements in the RFC:
2842
2843 The auto-replied keyword:
2844
2845 - SHOULD be used on messages sent in direct response to another
2846 message by an automatic process,
2847
2848 - MUST NOT be used on manually-generated messages,
2849
2850 - MAY be used on Delivery Status Notifications (DSNs) and Message
2851 Disposition Notifications (MDNs),

2891PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2892 canonical form (as documented). However, after a host name lookup from
2893 the IP address, check_host() was doing a simple string comparison with
2894 addresses acquired from the DNS when checking that the found name did
2895 have the original IP as one of its addresses. Since any found IPv6
2896 addresses are likely to be in abbreviated form, the comparison could
2897 fail. Luckily, there already exists a function for doing the comparison
2898 by converting both addresses to binary, so now that is used instead of
2899 the text comparison.

3145TF/07 Exim produced the error message "an SRV record indicated no SMTP
3146 service" if it encountered an MX record with an empty target hostname.
3147 The message is now "an MX or SRV record indicated no SMTP service".

3149TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
3150 if the DNS of the sending site is misconfigured. This is quite a
3151 common situation. This change restores the behaviour of treating a
3152 helo verification defer as a failure.

3163PH/01 When a transport filter timed out in a pipe delivery, and the pipe

3165 filter timeout was being overwritten with the pipe command error. Now the
3166 underlying error message should be appended to the second error message.

3173PH/03 The warning log line about a condition test deferring for a "warn" verb
3174 was being output only once per connection, rather than after each

3176 "warn" verbs). This seems wrong, so I have changed it.

3178TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3179 it should not have, which might have caused a crash in the right
3180 circumstances, but probably never did.

3182PH/04 Installed a modified version of Tony Finch's patch to make submission

PH
3196PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3197 with the definition in sysexits.h (which is #included earlier).
3198 Fortunately, Exim does not actually use EX_OK. The code used to try to
3199 preserve the sysexits.h value, by assumimg that macro definitions were
3200 scanned for macro replacements. I have been disabused of this notion,
3201 so now the code just undefines EX_OK before #including unistd.h.

PH
3203PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3204 in the smtp transport. When a block could not be written in a single
3205 write() function, the timeout was being re-applied to each part-write.
3206 This seems wrong - if the receiver was accepting one byte at a time it
3207 would take for ever. The timeout is now adjusted when this happens. It
3208 doesn't have to be particularly precise.

3237TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.

3240 obviously out-of-the-box. Patch from Alex Miller.

3242PH/08 The ${def test on a variable was returning false if the variable's

3246PH/09 The syntax error of a character other than { following "${if

3248 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3249 accidental colon was present, for example, could give incorrect results.

3274PH/15 The code I had for printing potentially long long variables in PH/11
3275 above was not the best (it lost precision). The length of off_t variables
3276 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3277 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3278 to be "long long int" or "long int". This is needed for the internal
3279 formatting function string_vformat().

3281PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3282 the configuration file to be ":syslog", then the script "guesses" where
3283 the logs files are, rather than using the compiled in default. In our
3284 case the guess is not the same as the compiled default, so the script
3285 suddenly stopped working when I started to use syslog. The patch checks
3286 to see if log_file_path is "". If so, it attempts to read it from exim
3287 with no configuration file to get the compiled in version, before it
3288 falls back to the previous guessing code."

3297PH/18 If the "use_postmaster" option was set for a recipient callout together

3300 test. It is now used for both.

PH
3302PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3303 patch removes a few documentation additions to RFC 3028, because the
3304 latest draft now contains them. It adds the new en;ascii-case comparator
3305 and a new error check for 8bit text in MIME parts. Comparator and
3306 require names are now matched exactly. I enabled the subaddress
3307 extension, but it is not well tested yet (read: it works for me)."

3309PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3310 rework some of the code of TK/09 above to avoid the hardwired use of

3319 experimental DomainKeys support:
3320
3321 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3322 (2) On an error such as an illegally used "control", the wrong name for
3323 the control was given.

PH
3331PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3332 databases so that it will be absolutely obvious if a crash occurs in the
3333 DB library. This is a regular occurrence (often caused by mis-matched
3334 db.h files).
3335
ff790e47 3336PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3337 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3338 picked up on a user's system that detects such things. There doesn't seem
3339 to be a gcc warning option for this - only an attribute that has to be
3340 put on the function's prototype. It seems that in Fedora Core 4 they have
3341 set this on a number of new functions. No doubt there will be more in due
3342 course.
