15
ad07e9ad
JH
16JH/03 The smtp transport now requests PRDR by default, if the server offers
17 it.
18
01a4a5c5 19JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 20 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
21 can be used to disable this per-host. The build option
22 EXPERIMENTAL_CERTNAMES is withdrawn.
23
cb1d7830 24JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 25 default to the word "system" to access the system default CA bundle.

JH
26 For GnuTLS, only version 3.0.20 or later.
27
610ff438 28JH/06 Verification of the server certificate for a TLS connection is now tried

29 (but not required) by default. The verification status is now logged by
30 default, for both outbound TLS and client-certificate supplying inbound
31 TLS connections
610ff438 32
f926e272
JH
33JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
34 sites use this now.
35
50dc7409
JH
36JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
37 Status Notification (bounce) messages are now MIME format per RFC 3464.
38 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
39 under the control of the dsn_advertise_hosts option, and routers may

43 default, modifiable by a malware= option. The list separator for
23763898 44 the options can now be changed in the usual way. Bug 68.
4e71661f 45
1ad6489e

AL
57JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
58 Patch from Andrew Lewis.
59
fd4d8871 60JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 61 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
62 modifiers per server. Patch originally by <rommer@active.by>.
63
64JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
65 and remote servers. Remote servers can be IPv6 addresses, and
66 specify a port-range.

102

JH
103JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
104 Normally benign, it bites when the pair was led to by a CNAME;
105 modern usage is to not canoicalize the domain to a CNAME target
106 (and we were inconsistent anyway for A-only vs AAAA+A).

TL
129Exim version 4.85
130-----------------
131TL/01 When running the test suite, the README says that variables such as
132 no_msglog_check are global and can be placed anywhere in a specific
133 test's script, however it was observed that placement needed to be near
134 the beginning for it to behave that way. Changed the runtest perl
135 script to read through the entire script once to detect and set these
136 variables, reset to the beginning of the script, and then run through
137 the script parsing/test process like normal.
138
ac20058f
TL
139TL/02 The BSD's have an arc4random API. One of the functions to induce
140 adding randomness was arc4random_stir(), but it has been removed in
141 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
142 function when detected.
143
a9b8ec8b
JH
144JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
145 cause callback expansion.
146
6286d7c4
TL
147TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
148 syntax errors in an expansion can be treated as a string instead of
149 logging or causing an error, due to the internal use of bool_lax
150 instead of bool when processing it.
151
0f06b4f2 152JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
153 server certificates when making smtp deliveries.

bd21a787
WB
164JH/05 Fix results-pipe from transport process. Several recipients, combined
165 with certificate use, exposed issues where response data items split
166 over buffer boundaries were not parsed properly. This eventually
167 resulted in duplicates being sent. This issue only became common enough
168 to notice due to the introduction of conection certificate information,
169 the item size being so much larger. Found and fixed by Wolfgang Breyha.
170
8bc732e8
JH
171JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
172 size buffer was used, resulting in syntax errors when an expansion
173 exceeded it.
174
a7fec7a7
JH
175JH/07 Add support for directories of certificates when compiled with a GnuTLS
176 version 3.3.6 or later.
177
774ef2d7
JH
178JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
179 is EXPERIMENTAL_EVENT, the main-configuration and transport options
180 both become "event_action", the variables become $event_name, $event_data
aec45841 181 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
182 routers, transports and related events. The tls:cert event is now also
183 raised for inbound connections, if the main configuration event_action
184 option is defined.

186TL/06 In test suite, disable OCSP for old versions of openssl which contained
187 early OCSP support, but no stapling (appears to be less than 1.0.0).
188
8d692470
JH
189JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
190 server certificate names available under the smtp transport option
191 "tls_verify_cert_hostname" now do not permit multi-component wildcard
192 matches.
193
e9477a08
JH
194JH/10 Time-related extraction expansions from certificates now use the main
195 option "timezone" setting for output formatting, and are consistent
196 between OpenSSL and GnuTLS compilations. Bug 1541.

202 include certificate info, eximon was claiming there were spoolfile
203 syntax errors.

238Exim version 4.83
239-----------------
240
241TF/01 Correctly close the server side of TLS when forking for delivery.
242
243 When a message was received over SMTP with TLS, Exim failed to clear up
244 the incoming connection properly after forking off the child process to
245 deliver the message. In some situations the subsequent outgoing
246 delivery connection happened to have the same fd number as the incoming
247 connection previously had. Exim would try to use TLS and fail, logging
248 a "Bad file descriptor" error.

8ddef691 278TL/05 Rename SPF condition results err_perm and err_temp to standardized
982650ec
TL
279 results permerror and temperror. Previous values are deprecated but
280 still accepted. In a future release, err_perm and err_temp will be
281 completely removed, which will be a backward incompatibility if the
282 ACL tests for either of these two old results. Patch contributed by
8ddef691 283 user bes-internal on the mailing list.

308 individually rather than the list as a whole. Bug 1452.
309

494TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
495
496 When a queue runner is handling a message, Exim first routes the
497 recipient addresses, during which it prunes them based on the retry
498 hints database. After that it attempts to deliver the message to
499 any remaining recipients. It then updates the hints database using
500 the retry rules.
501
502 So if a recipient address works intermittently, it can get repeatedly
503 deferred at routing time. The retry hints record remains fresh so the
504 address never reaches the final cutoff time.
505
506 This is a fairly common occurrence when a user is bumping up against
507 their storage quota. Exim had some logic in its local delivery code
508 to deal with this. However it did not apply to per-recipient defers
509 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
510
1ddeb334
TF
511 This change adds a proper retry rule check during routing so that the
512 final cutoff time is checked against the message's age. We only do
513 this check if there is an address retry record and there is not a
514 domain retry record; this implies that previous attempts to handle
515 the address had the retry_use_local_parts option turned on. We use
516 this as an approximation for the destination being like a local
517 delivery, as in LMTP.
67bd1ab3
TF
518
519 I suspect this new check makes the old local delivery cutoff check
520 redundant, but I have not verified this so I left the code in place.

529 the header to contain my full name, whereas it should have added
530 a Resent-Sender: header. It erroneously treats any prefix of the
531 username as equal to the username.

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

842TF/03 Make the exiwhat support code safe for signals. Previously Exim might
843 lock up or crash if it happened to be inside a call to libc when it
844 got a SIGUSR1 from exiwhat.
845
846 The SIGUSR1 handler appends the current process status to the process
847 log which is later printed by exiwhat. It used to use the general
848 purpose logging code to do this, but several functions it calls are
849 not safe for signals.
850
851 The new output code in the SIGUSR1 handler is specific to the process
852 log, and simple enough that it's easy to inspect for signal safety.
853 Removing some special cases also simplifies the general logging code.
854 Removing the spurious timestamps from the process log simplifies
855 exiwhat.

857TF/04 Improved ratelimit ACL condition.
858
859 The /noupdate option has been deprecated in favour of /readonly which
860 has clearer semantics. The /leaky, /strict, and /readonly update modes
861 are mutually exclusive. The update mode is no longer included in the
862 database key; it just determines when the database is updated. (This
863 means that when you upgrde Exim will forget old rate measurements.)
864
865 Exim now checks that the per_* options are used with an update mode that
866 makes sense for the current ACL. For example, when Exim is processing a
867 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
868 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
869 must specify per_mail/readonly. If you omit the update mode it defaults to
870 /leaky where that makes sense (as before) or /readonly where required.
871
872 The /noupdate option is now undocumented but still supported for
873 backwards compatibility. It is equivalent to /readonly except that in
874 ACLs where /readonly is required you may specify /leaky/noupdate or
875 /strict/noupdate which are treated the same as /readonly.
876
877 A useful new feature is the /count= option. This is a generalization
878 of the per_byte option, so that you can measure the throughput of other
879 aggregate values. For example, the per_byte option is now equivalent
880 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
881
882 The per_rcpt option has been generalized using the /count= mechanism
883 (though it's more complicated than the per_byte equivalence). When it is
884 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
885 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
886 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
887 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
888 Note that using per_rcpt with a non-readonly update mode in more than
889 one ACL will cause the recipients to be double-counted. (The per_mail
890 and per_byte options don't have this problem.)
891
892 The handling of very low rates has changed slightly. If the computed rate
893 is less than the event's count (usually one) then this event is the first
894 after a long gap. In this case the rate is set to the same as this event's
895 count, so that the first message of a spam run is counted properly.
896
897 The major new feature is a mechanism for counting the rate of unique
898 events. The new per_addr option counts the number of different
899 recipients that someone has sent messages to in the last time period. It
900 behaves like per_rcpt if all the recipient addresses are different, but
901 duplicate recipient addresses do not increase the measured rate. Like
902 the /count= option this is a general mechanism, so the per_addr option
903 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
904 example, measure the rate that a client uses different sender addresses
905 with the options per_mail/unique=$sender_address. There are further
906 details in the main documentation.

1457 were called 'true' and it seems that C99 defines that as a reserved

1477
1478PH/01 Another patch from the Sieve maintainer.
1479
6a3bceb1
PH
1480PH/02 When an IPv6 address is converted to a string for single-key lookup
1481 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1482 dots are used instead of colons so that keys in lsearch files need not
1483 contain colons. This was done some time before quoting was made available
1484 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1485 (notated using the quote facility) so as to distinguish them from IPv4
1486 keys. This meant that lookups for IP addresses in host lists did not work
1487 for iplsearch lookups.
1488
1489 This has been fixed by arranging for IPv6 addresses to be expressed with
1490 colons if the lookup type is iplsearch. This is not incompatible, because
1491 previously such lookups could never work.
1492
1493 The situation is now rather anomolous, since one *can* have colons in
1494 ordinary lsearch keys. However, making the change in all cases is
1495 incompatible and would probably break a number of configurations.

1500MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1501 conversion specification without a maximum field width, thereby enabling
1502 a rogue spamd server to cause a buffer overflow. While nobody in their
1503 right mind would setup Exim to query an untrusted spamd server, an
1504 attacker that gains access to a server running spamd could potentially
1505 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1510MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1511 a directory entry by the name of the lookup key. Previously, if a
1512 symlink pointed to a non-existing file or a file in a directory that
1513 Exim lacked permissions to read, a lookup for a key matching that
1514 symlink would fail. Now it is enough that a matching directory entry
1515 exists, symlink or not. (Bugzilla 503.)

1592 if a client was not listed at all, or was listed with a value other than

1698PH/29 SMTP synchronization checks are implemented when a command is read -
1699 there is a check that no more input is waiting when there shouldn't be
1700 any. However, for some commands, a delay in an ACL can mean that it is
1701 some time before the response is written. In this time, more input might
1702 arrive, invalidly. So now there are extra checks after an ACL has run for
1703 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1704 pipelining has not been advertised.

1719 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1720 was a macro that became an assignment, so it seemed to work. This has

PH
1778 the response to the final '.' that terminates a message, but only in the
1779 case where the client has not sent further data following the '.'
1780 (unfortunately, this is allowed). However, in many cases there won't be
1781 any further data because there won't be any more messages to send. A call
1782 to select() can be used: if it shows that the input is "ready", there is
1783 either input waiting, or the socket has been closed. An attempt to read
1784 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1785 would have sent an OK response which the client would never have see.

1796PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1797 fixed by 4.65/MH/01 (is this a record?) are fixed:
1798
1799 (i) An empty string was always treated as zero by the numeric comparison
1800 operators. This behaviour has been restored.
1801
1802 (ii) It is documented that the numeric comparison operators always treat
1803 their arguments as decimal numbers. This was broken in that numbers
1804 starting with 0 were being interpreted as octal.
1805
1806 While fixing these problems I realized that there was another issue that
1807 hadn't been noticed. Values of message_size_limit (both the global option
1808 and the transport option) were treated as octal if they started with 0.
1809 The documentation was vague. These values are now always treated as
1810 decimal, and I will make that clear in the documentation.

1826 is held in a short int, deliveries were likely to be lost. As such a
1827 large number of recipients for a single message is ridiculous

1845TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1854PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1855 callout verification, Exim cached a "reject" for the entire domain. This
1856 is correct for most verifications, but it is not correct for a recipient
1857 verification with use_sender or use_postmaster set, because in that case
1858 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1859 case of MAIL FROM:<> rejection from other early rejections (e.g.
1860 rejection of HELO). When verifying a recipient using a non-null MAIL
1861 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1862 Whatever the result of the callout, the value of the domain cache is
1863 left unchanged (for any other kind of callout, getting as far as trying
1864 RCPT means that the domain itself is ok).

1898PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1900 probably the interface on which it is arriving) and not to the outgoing
1901 callout (which could be using a different interface). This has been
1902 changed to use the value of the helo_data option from the smtp transport
1903 instead - this is what is used when a message is actually being sent. If
1904 there is no remote transport (possible with a router that sets up host
1905 addresses), $smtp_active_hostname is used.

7befa435 1908 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1909 (a) The code assumed that strncpy() returns a negative number on buffer
1910 overflow, which isn't the case. Replaced with Exim's string_format()
1911 function.
1912 (b) There were several signed/unsigned issues. I just did the minimum
1913 hacking in of casts. There is scope for a larger refactoring.
1914 (c) The code used strcasecmp() which is not a standard C function.
1915 Replaced with Exim's strcmpic() function.
1916 (d) The code set only $1; it now sets $auth1 as well.
1917 (e) A simple test gave the error "authentication client didn't specify
1918 service in request". It would seem that Dovecot has changed its
1919 interface. Fortunately there's a specification; I followed it and
1920 changed what the client sends and it appears to be working now.

1926 address A is aliased to B and C, where B exists and C does not. Without
1927 -v the output is "A verified" because verification stops after a
1928 successful redirection if more than one address is generated. However,
1929 with -v the child addresses are also verified. Exim was outputting "A
1930 failed to verify" and then showing the successful verification for C,
1931 with its parentage. It now outputs "B failed to verify", showing B's
1932 parentage before showing the successful verification of C.

PH
1938PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1939 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1940 they consult the DNS. I had assumed they would set it the way they
1941 wanted; and indeed my experiments on Linux seem to show that in some
1942 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1943 To be on the safe side, however, I have now made the interface to
1944 host_find_byname() similar to host_find_bydns(), with an argument
1945 containing the DNS resolver options. The host_find_byname() function now
1946 sets these options at its start, just as host_find_bydns() does. The smtp
1947 transport options dns_qualify_single and dns_search_parents are passed to
1948 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1949 of host_find_byname() use the default settings of RES_DEFNAMES
1950 (qualify_single) but not RES_DNSRCH (search_parents).

1956 Originally there were few.) While I was there, I also converted the

1958 character, in the hope this might squeeze out yet more improvement.

1960PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1961 flag allowing group syntax was set by the header_syntax check but not
1962 turned off, possible causing trouble later; (2) The flag was not being
1963 set at all for the header_verify test, causing "group"-style headers to
1964 be rejected. I have now set it in this case, and also caused header_
1965 verify to ignore an empty address taken from a group. While doing this, I
1966 came across some other cases where the code for allowing group syntax
1967 while scanning a header line wasn't quite right (mostly, not resetting
1968 the flag correctly in the right place). These bugs could have caused
1969 trouble for malformed header lines. I hope it is now all correct.

1971PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1973 came from elsewhere) had *some* tests for NULL when it wrote to *reply,

1977PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1978 feature that was used to support insecure browsers during the U.S. crypto
1979 embargo. It requires special client support, and Exim is probably the
1980 only MTA that supported it -- and would never use it because real RSA is
1981 always available. This code has been removed, because it had the bad
1982 effect of slowing Exim down by computing (never used) parameters for the
1983 RSA_EXPORT functionality.

1985PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1988 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1989 if the connection is using TLS or if the remote IP is the same as the
1990 local IP, and the "valid-client-cert option" if a client certificate has
1991 been verified.

2023PH/30 Exim was sometimes attempting to deliver messages that had suffered
2024 address errors (4xx response to RCPT) over the same connection as other
2025 messages routed to the same hosts. Such deliveries are always "forced",
2026 so retry times are not inspected. This resulted in far too many retries
2027 for the affected addresses. The effect occurred only when there were more
2028 hosts than the hosts_max_try setting in the smtp transport when it had
2029 the 4xx errors. Those hosts that it had tried were not added to the list
2030 of hosts for which the message was waiting, so if all were tried, there
2031 was no problem. Two fixes have been applied:
2032
2033 (i) If there are any address or message errors in an SMTP delivery, none
2034 of the hosts (tried or untried) are now added to the list of hosts
2035 for which the message is waiting, so the message should not be a
2036 candidate for sending over the same connection that was used for a
2037 successful delivery of some other message. This seems entirely
2038 reasonable: after all the message is NOT "waiting for some host".
2039 This is so "obvious" that I'm not sure why it wasn't done
2040 previously. Hope I haven't missed anything, but it can't do any
2041 harm, as the worst effect is to miss an optimization.
2042
2043 (ii) If, despite (i), such a delivery is accidentally attempted, the
2044 routing retry time is respected, so at least it doesn't keep
2045 hammering the server.

2060PH/35 The error "getsockname() failed: connection reset by peer" was being
2061 written to the panic log as well as the main log, but it isn't really
2062 panic-worthy as it just means the connection died rather early on. I have
2063 removed the panic log writing for the ECONNRESET error when getsockname()
2064 fails.
2065
48c7f9e2
PH
2066PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2067 runs only) independently of the message's sender address. This meant
2068 that, if the 4xx error was in fact related to the sender, a different
2069 message to the same recipient with a different sender could confuse
2070 things. In particualar, this can happen when sending to a greylisting
2071 server, but other circumstances could also provoke similar problems.
2072 I have changed the default so that the retry time for these errors is now
2073 based a combination of the sender and recipient addresses. This change
2074 can be overridden by setting address_retry_include_sender=false in the
2075 smtp transport.

2345 Unfortunately, if there is a major crisis, such as a disk failure,
2346 tcp-wrappers gives "deny", whereas what one would like would be some
2347 kind of temporary error. A kludge has been added to help with this.
2348 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2349 554 error is used if errno is still zero or contains ENOENT (which occurs
2350 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2351 451 error is used.

2373PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash

2376 used only to exclude .Trash (or whatever) when the size of the mailbox
2377 was calculated. There was no check that a delivery was happening into an

2387PH/01 The code for finding all the local interface addresses on a FreeBSD
2388 system running IPv6 was broken. This may well have applied to all BSD
2389 systems, as well as to others that have similar system calls. The broken
2390 code found IPv4 interfaces correctly, but gave incorrect values for the
2391 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2392 that it would not match correctly against @[] and not recognize the IPv6
2393 addresses as local.

2436 autoreply, Exim could try to deliver to a non-existent relative file

2472 Instead, it always explicitly searches for A/AAAA records. This avoids
2473 major problems that occur when a DNS server includes only records of one
2474 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2475 fixed another bug: if SRV records were looked up and the corresponding
2476 address records were *not* found in the additional section, the port
2477 values from the SRV records were lost.

PH
2487PH/19 When calculating a retry time, Exim used to measure the "time since
2488 failure" by looking at the "first failed" field in the retry record. Now
2489 it does not use this if it is later than than the arrival time of the
2490 message. Instead it uses the arrival time. This makes for better
2491 behaviour in cases where some deliveries succeed, thus re-setting the
2492 "first failed" field. An example is a quota failure for a huge message
2493 when small messages continue to be delivered. Without this change, the
2494 "time since failure" will always be short, possible causing more frequent
2495 delivery attempts for the huge message than are intended.

2592PH/42 The content-scanning code uses fopen() to create files in which to put

2595 files with open(), and sets the required mode explicitly. Thus, these
2596 files were ending up world-writeable. This was not a big issue, because,
2597 being within the spool directory, they were not world-accessible. I have
2598 created a function called modefopen, which takes an additional mode
2599 argument. It sets umask(777), creates the file, chmods it to the required
2600 mode, then resets the umask. All the relevant calls to fopen() in the

2641 was used in LMTP mode. This meant that they could be retried too
2642 frequently, and not timed out correctly.
2643
2644 (ii) Exim was setting the flag that allows error details to be returned
2645 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2646 recipients that were returned after the DATA command.
2647
2648PH/53 This is related to PH/52, but is more general: for any failing address,
2649 when detailed error information was permitted to be returned to the

2728 descriptor number as the socket. This naturally causes chaos. The fix is
2729 not to close the socket in ip_connect(); the socket should be closed by
2730 the function that creates it. There was only one place in the code where
2731 this was missing, in the iplookup router, which I don't think anybody now
2732 uses, but I've fixed it anyway.

2751PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2752
2753 (1) Generate an error if the third argument for the ${prvs expansion is
2754 not a single digit.
2755
2756 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2757 string.
2758
2759 (3) Reset the variables that are obtained from the first argument of
2760 ${prvscheck and used in the second argument before leaving the code,
2761 because their memory is reclaimed, so using them afterwards may do
2762 silly things.
2763
2764 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2765 one (it's much easier than Tom thought :-).
2766
2767 (5) Because of (4), we can now allow for the use of $prvscheck_result
2768 inside the third argument.

2778 quoted in the delivery log line, like this:
2779
2780 => >A.N.Other <ano@some.domain> <original@ddress> ...
2781
2782 This has been changed so that it extracts the operative address. There
2783 may be more than one such address. If so, they are comma-separated, like
2784 this:
2785

PH
2788PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2789 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2790 not being looked up in the rDNS to get a host name, Exim was showing the
2791 IP address twice in Received: lines, even though the IP addresses were
2792 identical. For example:
2793
2794 Received: from [1.2.3.4] (helo=[1.2.3.4])
2795
2796 However, if the real host name was known, it was omitting the HELO data
2797 if it matched the actual IP address. This has been tidied up so that it
2798 doesn't show the same IP address twice.

PH
2824PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2825 Electronic Mail") by including:
2826
2827 Auto-submitted: auto-generated
2828
2829 in the messages that it generates (bounce messages and others, such as
2830 warnings). In the case of bounce messages for non-SMTP mesages, there was
2831 also a typo: it was using "Auto_submitted" (underscore instead of
2832 hyphen). Since every message generated by Exim is necessarily in response
2833 to another message, thes have all been changed to:
2834
2835 Auto-Submitted: auto-replied
2836
2837 in accordance with these statements in the RFC:
2838
2839 The auto-replied keyword:
2840
2841 - SHOULD be used on messages sent in direct response to another
2842 message by an automatic process,
2843
2844 - MUST NOT be used on manually-generated messages,
2845
2846 - MAY be used on Delivery Status Notifications (DSNs) and Message
2847 Disposition Notifications (MDNs),

2887PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2888 canonical form (as documented). However, after a host name lookup from
2889 the IP address, check_host() was doing a simple string comparison with
2890 addresses acquired from the DNS when checking that the found name did
2891 have the original IP as one of its addresses. Since any found IPv6
2892 addresses are likely to be in abbreviated form, the comparison could
2893 fail. Luckily, there already exists a function for doing the comparison
2894 by converting both addresses to binary, so now that is used instead of
2895 the text comparison.

2897PH/20 There was another similar case to PH/19, when a complete host name was

3141TF/07 Exim produced the error message "an SRV record indicated no SMTP
3142 service" if it encountered an MX record with an empty target hostname.
3143 The message is now "an MX or SRV record indicated no SMTP service".

3145TF/08 Change PH/13 introduced the possibility that verify=helo may defer,
3146 if the DNS of the sending site is misconfigured. This is quite a
3147 common situation. This change restores the behaviour of treating a
3148 helo verification defer as a failure.

3159PH/01 When a transport filter timed out in a pipe delivery, and the pipe
3160 command itself ended in error, the underlying message about the transport
3161 filter timeout was being overwritten with the pipe command error. Now the
3162 underlying error message should be appended to the second error message.

3169PH/03 The warning log line about a condition test deferring for a "warn" verb
3170 was being output only once per connection, rather than after each
3171 occurrence (because it was using the same function as for successful
3172 "warn" verbs). This seems wrong, so I have changed it.

3174TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3175 it should not have, which might have caused a crash in the right
3176 circumstances, but probably never did.
3177
3178PH/04 Installed a modified version of Tony Finch's patch to make submission
3179 mode fix the return path as well as the Sender: header line, and to

PH
3192PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3193 with the definition in sysexits.h (which is #included earlier).
3194 Fortunately, Exim does not actually use EX_OK. The code used to try to
3195 preserve the sysexits.h value, by assumimg that macro definitions were
3196 scanned for macro replacements. I have been disabused of this notion,
3197 so now the code just undefines EX_OK before #including unistd.h.

PH
3199PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3200 in the smtp transport. When a block could not be written in a single
3201 write() function, the timeout was being re-applied to each part-write.
3202 This seems wrong - if the receiver was accepting one byte at a time it
3203 would take for ever. The timeout is now adjusted when this happens. It
3204 doesn't have to be particularly precise.

3229TK/06 MBOX spool code: Add real "From " MBOX separator line
3230 so the .eml file is really in mbox format (even though
3231 most programs do not really care). Patch from Alex Miller.

3233TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.

3236 obviously out-of-the-box. Patch from Alex Miller.

3238PH/08 The ${def test on a variable was returning false if the variable's

3242PH/09 The syntax error of a character other than { following "${if
3243 def:variable_name" (after optional whitespace) was not being diagnosed.
3244 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3245 accidental colon was present, for example, could give incorrect results.

3251PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.

3270PH/15 The code I had for printing potentially long long variables in PH/11
3271 above was not the best (it lost precision). The length of off_t variables
3272 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3273 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3274 to be "long long int" or "long int". This is needed for the internal
3275 formatting function string_vformat().

PH
3277PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3278 the configuration file to be ":syslog", then the script "guesses" where
3279 the logs files are, rather than using the compiled in default. In our
3280 case the guess is not the same as the compiled default, so the script
3281 suddenly stopped working when I started to use syslog. The patch checks
3282 to see if log_file_path is "". If so, it attempts to read it from exim
3283 with no configuration file to get the compiled in version, before it
3284 falls back to the previous guessing code."

PH
3293PH/18 If the "use_postmaster" option was set for a recipient callout together
3294 with the "random" option, the postmaster address was used as the MAIL
3295 FROM address for the random test, but not for the subsequent recipient
3296 test. It is now used for both.

PH
3298PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3299 patch removes a few documentation additions to RFC 3028, because the
3300 latest draft now contains them. It adds the new en;ascii-case comparator
3301 and a new error check for 8bit text in MIME parts. Comparator and
3302 require names are now matched exactly. I enabled the subaddress
3303 extension, but it is not well tested yet (read: it works for me)."

PH
3305PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3306 rework some of the code of TK/09 above to avoid the hardwired use of
3307 "%lld" and "long long". Replaced the call to snprintf() with a call to
3308 string_vformat().

3314PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3315 experimental DomainKeys support:
3316
3317 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3318 (2) On an error such as an illegally used "control", the wrong name for
3319 the control was given.

PH
3327PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3328 databases so that it will be absolutely obvious if a crash occurs in the
3329 DB library. This is a regular occurrence (often caused by mis-matched
3330 db.h files).
3331
ff790e47 3332PH/26 Insert a lot of missing (void) casts for functions such as chown(),

PH
3333 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3334 picked up on a user's system that detects such things. There doesn't seem
3335 to be a gcc warning option for this - only an attribute that has to be
3336 put on the function's prototype. It seems that in Fedora Core 4 they have
3337 set this on a number of new functions. No doubt there will be more in due
3338 course.
