5Exim version 4.86
6-----------------
7JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
8 expanded.

506900af
JH
10JH/02 The smtp transport option "multi_domain" is now expanded.
11
ad07e9ad
JH
12JH/03 The smtp transport now requests PRDR by default, if the server offers
13 it.
14
01a4a5c5
JH
15JH/04 Certificate name checking on server certificates, when exim is a client,
16 is now done by default. The transport option tls_verify_cert_hostname
17 can be used to disable this per-host. The build option
18 EXPERIMENTAL_CERTNAMES is withdrawn.
19
cb1d7830 20JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 21 default to the word "system" to access the system default CA bundle.
cb1d7830
JH
22 For GnuTLS, only version 3.0.20 or later.
23
610ff438 24JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
25 (but not required) by default. The verification status is now logged by
26 default, for both outbound TLS and client-certificate supplying inbound
27 TLS connections
610ff438 28
f926e272
JH
29JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
30 sites use this now.
31
50dc7409
JH
32JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
33 Status Notification (bounce) messages are now MIME format per RFC 3464.
34 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
35 under the control of the dsn_advertise_hosts option, and routers may
36 have a dsn_lasthop option.
37
0f0c8159
JH
38JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
39 default, modifiable by a malware= option. The list separator for
40 the options can now be changed in the usual way.
4e71661f 41
1ad6489e
JH
42JH/10 The smtp_receive_timeout main option is now expanded before use.
43
aeaf5db3

49Exim version 4.85
50-----------------
51TL/01 When running the test suite, the README says that variables such as
52 no_msglog_check are global and can be placed anywhere in a specific
53 test's script, however it was observed that placement needed to be near
54 the beginning for it to behave that way. Changed the runtest perl
55 script to read through the entire script once to detect and set these
56 variables, reset to the beginning of the script, and then run through
57 the script parsing/test process like normal.
58
ac20058f
TL
59TL/02 The BSD's have an arc4random API. One of the functions to induce
60 adding randomness was arc4random_stir(), but it has been removed in
61 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
62 function when detected.
63
a9b8ec8b
JH
64JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
65 cause callback expansion.
66
6286d7c4
TL
67TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
68 syntax errors in an expansion can be treated as a string instead of
69 logging or causing an error, due to the internal use of bool_lax
70 instead of bool when processing it.
71
0f06b4f2 72JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
73 server certificates when making smtp deliveries.
74
be36e572
JH
75JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
76
ac4ef9bd
JH
77JH/04 Add ${sort {list}{condition}{extractor}} expansion item.

81TL/05 GitHub Issue 18: Adjust logic testing for true/false in redis lookups.
82 Merged patch from Sebastian Wiedenroth.
e449c3b0 83
bd21a787
WB
84JH/05 Fix results-pipe from transport process. Several recipients, combined
85 with certificate use, exposed issues where response data items split
86 over buffer boundaries were not parsed properly. This eventually
87 resulted in duplicates being sent. This issue only became common enough
88 to notice due to the introduction of conection certificate information,
89 the item size being so much larger. Found and fixed by Wolfgang Breyha.
90
8bc732e8
JH
91JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
92 size buffer was used, resulting in syntax errors when an expansion
93 exceeded it.
94
a7fec7a7
JH
95JH/07 Add support for directories of certificates when compiled with a GnuTLS
96 version 3.3.6 or later.
97
774ef2d7
JH
98JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
99 is EXPERIMENTAL_EVENT, the main-configuration and transport options
100 both become "event_action", the variables become $event_name, $event_data
aec45841 101 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
102 routers, transports and related events. The tls:cert event is now also
103 raised for inbound connections, if the main configuration event_action
104 option is defined.
774ef2d7 105
eca4debb
TL
106TL/06 In test suite, disable OCSP for old versions of openssl which contained
107 early OCSP support, but no stapling (appears to be less than 1.0.0).
108
8d692470
JH
109JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
110 server certificate names available under the smtp transport option
111 "tls_verify_cert_hostname" now do not permit multi-component wildcard
112 matches.
113
e9477a08
JH
114JH/10 Time-related extraction expansions from certificates now use the main
115 option "timezone" setting for output formatting, and are consistent
116 between OpenSSL and GnuTLS compilations. Bug 1541.
117
ad4c5ff9
JH
118JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
119 encoded parameter in the incoming message. Bug 1558.

JH
120
121JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
122 include certificate info, eximon was claiming there were spoolfile
123 syntax errors.
124

128 "H=<name> [<ip>]" wherever possible.

TL
130TL/07 Bug 1547: Omit RFCs from release. Draft and RFCs have licenses which
131 are problematic for Debian distribution, omit them from the release
132 tarball.

146 checkers that were complaining about end of non-void function with no
147 return.

158Exim version 4.83
159-----------------
160
161TF/01 Correctly close the server side of TLS when forking for delivery.
162
163 When a message was received over SMTP with TLS, Exim failed to clear up
164 the incoming connection properly after forking off the child process to
165 deliver the message. In some situations the subsequent outgoing
166 delivery connection happened to have the same fd number as the incoming
167 connection previously had. Exim would try to use TLS and fail, logging
168 a "Bad file descriptor" error.
169
7245734e
TF
170TF/02 Portability fix for building lookup modules on Solaris when the xpg4
171 utilities have not been installed.
172
fd5dad68
JH
173JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
174 temporary space as the ACL may create new global variables.
175
5428a946
TL
176TL/01 LDAP support uses per connection or global context settings, depending
177 upon the detected version of the libraries at build time.
178
a3c86431
TL
179TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
180 to extract and use the src ip:port in logging and expansions as if it
8ded8589
TL
181 were a direct connection from the outside internet. PPv2 support was
182 updated based on HAProxy spec change in May 2014.

197
8ddef691 198TL/05 Rename SPF condition results err_perm and err_temp to standardized
982650ec
TL
199 results permerror and temperror. Previous values are deprecated but
200 still accepted. In a future release, err_perm and err_temp will be
201 completely removed, which will be a backward incompatibility if the
202 ACL tests for either of these two old results. Patch contributed by
8ddef691 203 user bes-internal on the mailing list.

JH
227JH/12 Expand items in router/transport headers_add or headers_remove lists
228 individually rather than the list as a whole. Bug 1452.
229
230 Required for reasonable handling of multiple headers_ options when
231 they may be empty; requires that headers_remove items with embedded
232 colons must have them doubled (or the list-separator changed).
233

414TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
415
416 When a queue runner is handling a message, Exim first routes the
417 recipient addresses, during which it prunes them based on the retry
418 hints database. After that it attempts to deliver the message to
419 any remaining recipients. It then updates the hints database using
420 the retry rules.
421
422 So if a recipient address works intermittently, it can get repeatedly
423 deferred at routing time. The retry hints record remains fresh so the
424 address never reaches the final cutoff time.
425
426 This is a fairly common occurrence when a user is bumping up against
427 their storage quota. Exim had some logic in its local delivery code
428 to deal with this. However it did not apply to per-recipient defers
429 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
430
1ddeb334
TF
431 This change adds a proper retry rule check during routing so that the
432 final cutoff time is checked against the message's age. We only do
433 this check if there is an address retry record and there is not a
434 domain retry record; this implies that previous attempts to handle
435 the address had the retry_use_local_parts option turned on. We use
436 this as an approximation for the destination being like a local
437 delivery, as in LMTP.
67bd1ab3
TF
438
439 I suspect this new check makes the old local delivery cutoff check
440 redundant, but I have not verified this so I left the code in place.

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

475 Server implementation by Todd Lyons, client by JH.
476 Only enabled when compiled with EXPERIMENTAL_PRDR. A new

478 advertises the facility. If the client requests PRDR a new
479 acl_data_smtp_prdr ACL is called once for each recipient, after
480 the body content is received and before the acl_smtp_data ACL.
481 The client is controlled by bolth of: a hosts_try_prdr option
482 on the smtp transport, and the server advertisement.
483 Default client logging of deliveries and rejections involving
484 PRDR are flagged with the string "PRDR".

762TF/03 Make the exiwhat support code safe for signals. Previously Exim might
763 lock up or crash if it happened to be inside a call to libc when it
764 got a SIGUSR1 from exiwhat.
765
766 The SIGUSR1 handler appends the current process status to the process
767 log which is later printed by exiwhat. It used to use the general
768 purpose logging code to do this, but several functions it calls are
769 not safe for signals.
770
771 The new output code in the SIGUSR1 handler is specific to the process
772 log, and simple enough that it's easy to inspect for signal safety.
773 Removing some special cases also simplifies the general logging code.
774 Removing the spurious timestamps from the process log simplifies
775 exiwhat.

TF
777TF/04 Improved ratelimit ACL condition.
778
779 The /noupdate option has been deprecated in favour of /readonly which
780 has clearer semantics. The /leaky, /strict, and /readonly update modes
781 are mutually exclusive. The update mode is no longer included in the
782 database key; it just determines when the database is updated. (This
783 means that when you upgrde Exim will forget old rate measurements.)
784
785 Exim now checks that the per_* options are used with an update mode that
786 makes sense for the current ACL. For example, when Exim is processing a
787 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
788 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
789 must specify per_mail/readonly. If you omit the update mode it defaults to
790 /leaky where that makes sense (as before) or /readonly where required.
791
792 The /noupdate option is now undocumented but still supported for
793 backwards compatibility. It is equivalent to /readonly except that in
794 ACLs where /readonly is required you may specify /leaky/noupdate or
795 /strict/noupdate which are treated the same as /readonly.
796
797 A useful new feature is the /count= option. This is a generalization
798 of the per_byte option, so that you can measure the throughput of other
799 aggregate values. For example, the per_byte option is now equivalent
800 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
801
802 The per_rcpt option has been generalized using the /count= mechanism
803 (though it's more complicated than the per_byte equivalence). When it is
804 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
805 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
806 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
807 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
808 Note that using per_rcpt with a non-readonly update mode in more than
809 one ACL will cause the recipients to be double-counted. (The per_mail
810 and per_byte options don't have this problem.)
811
812 The handling of very low rates has changed slightly. If the computed rate
813 is less than the event's count (usually one) then this event is the first
814 after a long gap. In this case the rate is set to the same as this event's
815 count, so that the first message of a spam run is counted properly.
816
817 The major new feature is a mechanism for counting the rate of unique
818 events. The new per_addr option counts the number of different
819 recipients that someone has sent messages to in the last time period. It
820 behaves like per_rcpt if all the recipient addresses are different, but
821 duplicate recipient addresses do not increase the measured rate. Like
822 the /count= option this is a general mechanism, so the per_addr option
823 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
824 example, measure the rate that a client uses different sender addresses
825 with the options per_mail/unique=$sender_address. There are further
826 details in the main documentation.

1399
6a3bceb1
PH
1400PH/02 When an IPv6 address is converted to a string for single-key lookup
1401 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1402 dots are used instead of colons so that keys in lsearch files need not
1403 contain colons. This was done some time before quoting was made available
1404 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1405 (notated using the quote facility) so as to distinguish them from IPv4
1406 keys. This meant that lookups for IP addresses in host lists did not work
1407 for iplsearch lookups.
1408
1409 This has been fixed by arranging for IPv6 addresses to be expressed with
1410 colons if the lookup type is iplsearch. This is not incompatible, because
1411 previously such lookups could never work.
1412
1413 The situation is now rather anomolous, since one *can* have colons in
1414 ordinary lsearch keys. However, making the change in all cases is
1415 incompatible and would probably break a number of configurations.

1420MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1421 conversion specification without a maximum field width, thereby enabling
1422 a rogue spamd server to cause a buffer overflow. While nobody in their
1423 right mind would setup Exim to query an untrusted spamd server, an
1424 attacker that gains access to a server running spamd could potentially
1425 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1430MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1431 a directory entry by the name of the lookup key. Previously, if a
1432 symlink pointed to a non-existing file or a file in a directory that
1433 Exim lacked permissions to read, a lookup for a key matching that
1434 symlink would fail. Now it is enough that a matching directory entry
1435 exists, symlink or not. (Bugzilla 503.)

1618PH/29 SMTP synchronization checks are implemented when a command is read -
1619 there is a check that no more input is waiting when there shouldn't be
1620 any. However, for some commands, a delay in an ACL can mean that it is
1621 some time before the response is written. In this time, more input might
1622 arrive, invalidly. So now there are extra checks after an ACL has run for
1623 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1624 pipelining has not been advertised.

1698 the response to the final '.' that terminates a message, but only in the
1699 case where the client has not sent further data following the '.'
1700 (unfortunately, this is allowed). However, in many cases there won't be
1701 any further data because there won't be any more messages to send. A call
1702 to select() can be used: if it shows that the input is "ready", there is
1703 either input waiting, or the socket has been closed. An attempt to read
1704 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1705 would have sent an OK response which the client would never have see.

1715
1716PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1717 fixed by 4.65/MH/01 (is this a record?) are fixed:
1718
1719 (i) An empty string was always treated as zero by the numeric comparison
1720 operators. This behaviour has been restored.
1721
1722 (ii) It is documented that the numeric comparison operators always treat
1723 their arguments as decimal numbers. This was broken in that numbers
1724 starting with 0 were being interpreted as octal.
1725
1726 While fixing these problems I realized that there was another issue that
1727 hadn't been noticed. Values of message_size_limit (both the global option
1728 and the transport option) were treated as octal if they started with 0.
1729 The documentation was vague. These values are now always treated as
1730 decimal, and I will make that clear in the documentation.

1746 is held in a short int, deliveries were likely to be lost. As such a
1747 large number of recipients for a single message is ridiculous
1748 (performance will be very, very poor), I have chosen to impose a limit
1749 rather than extend the field.

2b1c6e3a
PH
1774PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1775 callout verification, Exim cached a "reject" for the entire domain. This
1776 is correct for most verifications, but it is not correct for a recipient
1777 verification with use_sender or use_postmaster set, because in that case
1778 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1779 case of MAIL FROM:<> rejection from other early rejections (e.g.
1780 rejection of HELO). When verifying a recipient using a non-null MAIL
1781 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1782 Whatever the result of the callout, the value of the domain cache is
1783 left unchanged (for any other kind of callout, getting as far as trying
1784 RCPT means that the domain itself is ok).

1818PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1820 probably the interface on which it is arriving) and not to the outgoing
1821 callout (which could be using a different interface). This has been
1822 changed to use the value of the helo_data option from the smtp transport
1823 instead - this is what is used when a message is actually being sent. If
1824 there is no remote transport (possible with a router that sets up host
1825 addresses), $smtp_active_hostname is used.

7befa435 1828 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1829 (a) The code assumed that strncpy() returns a negative number on buffer
1830 overflow, which isn't the case. Replaced with Exim's string_format()
1831 function.
1832 (b) There were several signed/unsigned issues. I just did the minimum
1833 hacking in of casts. There is scope for a larger refactoring.
1834 (c) The code used strcasecmp() which is not a standard C function.
1835 Replaced with Exim's strcmpic() function.
1836 (d) The code set only $1; it now sets $auth1 as well.
1837 (e) A simple test gave the error "authentication client didn't specify
1838 service in request". It would seem that Dovecot has changed its
1839 interface. Fortunately there's a specification; I followed it and
1840 changed what the client sends and it appears to be working now.

1846 address A is aliased to B and C, where B exists and C does not. Without
1847 -v the output is "A verified" because verification stops after a
1848 successful redirection if more than one address is generated. However,
1849 with -v the child addresses are also verified. Exim was outputting "A
1850 failed to verify" and then showing the successful verification for C,
1851 with its parentage. It now outputs "B failed to verify", showing B's
1852 parentage before showing the successful verification of C.

1857
322050c2
PH
1858PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1859 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1860 they consult the DNS. I had assumed they would set it the way they
1861 wanted; and indeed my experiments on Linux seem to show that in some
1862 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1863 To be on the safe side, however, I have now made the interface to
1864 host_find_byname() similar to host_find_bydns(), with an argument
1865 containing the DNS resolver options. The host_find_byname() function now
1866 sets these options at its start, just as host_find_bydns() does. The smtp
1867 transport options dns_qualify_single and dns_search_parents are passed to
1868 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1869 of host_find_byname() use the default settings of RES_DEFNAMES
1870 (qualify_single) but not RES_DNSRCH (search_parents).

1872PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1873 spool_read_header() do less string testing, by means of a preliminary
1874 switch on the second character of optional "-foo" lines. (This is
1875 overdue, caused by the large number of possibilities that now exist.
1876 Originally there were few.) While I was there, I also converted the
1877 str(n)cmp tests so they don't re-test the leading "-" and the first
1878 character, in the hope this might squeeze out yet more improvement.

PH
1880PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1881 flag allowing group syntax was set by the header_syntax check but not
1882 turned off, possible causing trouble later; (2) The flag was not being
1883 set at all for the header_verify test, causing "group"-style headers to
1884 be rejected. I have now set it in this case, and also caused header_
1885 verify to ignore an empty address taken from a group. While doing this, I
1886 came across some other cases where the code for allowing group syntax
1887 while scanning a header line wasn't quite right (mostly, not resetting
1888 the flag correctly in the right place). These bugs could have caused
1889 trouble for malformed header lines. I hope it is now all correct.

PH
1891PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1892 with the "reply" argument non-NULL. The code, however (which originally
1893 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1894 but it didn't always do it. This confused somebody who was copying the
1895 code for some other use. I have removed all the tests.

PH
1897PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1898 feature that was used to support insecure browsers during the U.S. crypto
1899 embargo. It requires special client support, and Exim is probably the
1900 only MTA that supported it -- and would never use it because real RSA is
1901 always available. This code has been removed, because it had the bad
1902 effect of slowing Exim down by computing (never used) parameters for the
1903 RSA_EXPORT functionality.

1908 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1909 if the connection is using TLS or if the remote IP is the same as the
1910 local IP, and the "valid-client-cert option" if a client certificate has
1911 been verified.

1942
1943PH/30 Exim was sometimes attempting to deliver messages that had suffered
1944 address errors (4xx response to RCPT) over the same connection as other
1945 messages routed to the same hosts. Such deliveries are always "forced",
1946 so retry times are not inspected. This resulted in far too many retries
1947 for the affected addresses. The effect occurred only when there were more
1948 hosts than the hosts_max_try setting in the smtp transport when it had
1949 the 4xx errors. Those hosts that it had tried were not added to the list
1950 of hosts for which the message was waiting, so if all were tried, there
1951 was no problem. Two fixes have been applied:
1952
1953 (i) If there are any address or message errors in an SMTP delivery, none
1954 of the hosts (tried or untried) are now added to the list of hosts
1955 for which the message is waiting, so the message should not be a
1956 candidate for sending over the same connection that was used for a
1957 successful delivery of some other message. This seems entirely
1958 reasonable: after all the message is NOT "waiting for some host".

1986PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1987 runs only) independently of the message's sender address. This meant
1988 that, if the 4xx error was in fact related to the sender, a different
1989 message to the same recipient with a different sender could confuse
1990 things. In particualar, this can happen when sending to a greylisting
1991 server, but other circumstances could also provoke similar problems.
1992 I have changed the default so that the retry time for these errors is now
1993 based a combination of the sender and recipient addresses. This change
1994 can be overridden by setting address_retry_include_sender=false in the
1995 smtp transport.

2266 tcp-wrappers gives "deny", whereas what one would like would be some
2267 kind of temporary error. A kludge has been added to help with this.
2268 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2269 554 error is used if errno is still zero or contains ENOENT (which occurs
2270 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2353PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
2354 syntactically invalid From: or Reply-to: line, and a filter used this to
2355 generate an autoreply, and therefore failed to obtain an address for the
2356 autoreply, Exim could try to deliver to a non-existent relative file
2357 name, causing unrelated and misleading errors. What now happens is that
2358 it logs this as a hard delivery error, but does not attempt to create a
2359 bounce message.

2373PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

2376 non-existent - all you got was a failure to exec. I have made two
2377 changes:
2378
2379 (a) Failures to set uid/gid, the current directory, or a process leader
2380 in a subprocess such as that created by queryprogram now generate
2381 suitable debugging ouput when -d is set.
2382

2385 the subprocess without attempting to change uid/gid.

2390PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2391 additional section of a DNS packet that returns MX or SRV records.
2392 Instead, it always explicitly searches for A/AAAA records. This avoids
2393 major problems that occur when a DNS server includes only records of one
2394 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2395 fixed another bug: if SRV records were looked up and the corresponding
2396 address records were *not* found in the additional section, the port
2397 values from the SRV records were lost.

PH
2407PH/19 When calculating a retry time, Exim used to measure the "time since
2408 failure" by looking at the "first failed" field in the retry record. Now
2409 it does not use this if it is later than than the arrival time of the
2410 message. Instead it uses the arrival time. This makes for better
2411 behaviour in cases where some deliveries succeed, thus re-setting the
2412 "first failed" field. An example is a quota failure for a huge message
2413 when small messages continue to be delivered. Without this change, the
2414 "time since failure" will always be short, possible causing more frequent
2415 delivery attempts for the huge message than are intended.

PH
2512PH/42 The content-scanning code uses fopen() to create files in which to put
2513 message data. Previously it was not paying any attention to the mode of
2514 the files. Exim runs with umask(0) because the rest of the code creates
2515 files with open(), and sets the required mode explicitly. Thus, these
2516 files were ending up world-writeable. This was not a big issue, because,
2517 being within the spool directory, they were not world-accessible. I have
2518 created a function called modefopen, which takes an additional mode
2519 argument. It sets umask(777), creates the file, chmods it to the required
2520 mode, then resets the umask. All the relevant calls to fopen() in the
2521 content scanning code have been changed to use this function.

2533 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2557 used in LMTP mode:
2558
2559 (i) Exim was not creating retry information for temporary errors given
2560 for individual recipients after the DATA command when the smtp transport
2561 was used in LMTP mode. This meant that they could be retried too
2562 frequently, and not timed out correctly.
2563
2564 (ii) Exim was setting the flag that allows error details to be returned
2565 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2566 recipients that were returned after the DATA command.
2567
2568PH/53 This is related to PH/52, but is more general: for any failing address,
2569 when detailed error information was permitted to be returned to the
2570 sender, but the error was temporary, then after the final timeout, only
2571 "retry timeout exceeded" was returned. Now it returns the full error as

2642PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2643 function verify_get_ident() calls ip_connect() to connect a socket, but
2644 if the "connect()" function timed out, ip_connect() used to close the
2645 socket. However, verify_get_ident() also closes the socket later, and in
2646 between Exim writes to the log, which may get opened at this point. When
2647 the socket was closed in ip_connect(), the log could get the same file
2648 descriptor number as the socket. This naturally causes chaos. The fix is
2649 not to close the socket in ip_connect(); the socket should be closed by
2650 the function that creates it. There was only one place in the code where
2651 this was missing, in the iplookup router, which I don't think anybody now
2652 uses, but I've fixed it anyway.

2713
2714 Received: from [1.2.3.4] (helo=[1.2.3.4])

2751 also a typo: it was using "Auto_submitted" (underscore instead of
2752 hyphen). Since every message generated by Exim is necessarily in response
2753 to another message, thes have all been changed to:
2754
2755 Auto-Submitted: auto-replied
2756
2757 in accordance with these statements in the RFC:
2758
2759 The auto-replied keyword:
2760
2761 - SHOULD be used on messages sent in direct response to another
2762 message by an automatic process,
2763
2764 - MUST NOT be used on manually-generated messages,
2765
2766 - MAY be used on Delivery Status Notifications (DSNs) and Message
2767 Disposition Notifications (MDNs),
2768
2769 - MUST NOT be used on messages generated by automatic or periodic
2770 processes, except for messages which are automatic responses to
2771 other messages.

2807PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2808 canonical form (as documented). However, after a host name lookup from
2809 the IP address, check_host() was doing a simple string comparison with
2810 addresses acquired from the DNS when checking that the found name did
2811 have the original IP as one of its addresses. Since any found IPv6
2812 addresses are likely to be in abbreviated form, the comparison could
2813 fail. Luckily, there already exists a function for doing the comparison
2814 by converting both addresses to binary, so now that is used instead of
2815 the text comparison.

PH
2817PH/20 There was another similar case to PH/19, when a complete host name was

3153TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
3154 The latter is generated from $received_to and is only set if the

3156 obviously out-of-the-box. Patch from Alex Miller.

3158PH/08 The ${def test on a variable was returning false if the variable's

3162PH/09 The syntax error of a character other than { following "${if

3164 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3165 accidental colon was present, for example, could give incorrect results.

3190PH/15 The code I had for printing potentially long long variables in PH/11

3193 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3194 to be "long long int" or "long int". This is needed for the internal
3195 formatting function string_vformat().

3197PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3198 the configuration file to be ":syslog", then the script "guesses" where
3199 the logs files are, rather than using the compiled in default. In our
3200 case the guess is not the same as the compiled default, so the script
3201 suddenly stopped working when I started to use syslog. The patch checks
3202 to see if log_file_path is "". If so, it attempts to read it from exim
3203 with no configuration file to get the compiled in version, before it
3204 falls back to the previous guessing code."

3221 and a new error check for 8bit text in MIME parts. Comparator and

3247PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3248 databases so that it will be absolutely obvious if a crash occurs in the

3253 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3254 picked up on a user's system that detects such things. There doesn't seem
3255 to be a gcc warning option for this - only an attribute that has to be
3256 put on the function's prototype. It seems that in Fedora Core 4 they have
3257 set this on a number of new functions. No doubt there will be more in due
3258 course.

PH
3260PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3261 specify a transport. However, if an address that was verified by such a
3262 router was the subject of a callout, Exim crashed because it tried to
3263 read the rcpt_include_affixes from the non-existent transport. Now it
3264 just assumes that the setting of that option is false. This bug was
3265 introduced by 4.51/PH/31.

3275PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3276 aren't the modern standard, and it seems that some systems' include files
3277 don't always have them. Exim was already checking for some of the newer
3278 ones like T_AAAA, and defining it itself. I've added checks for all the
3279 record types that Exim uses.

3281PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3282 not automatically generating a new one, as it is supposed to. This

3284 data, a new version was generated, as expected. It was only the case of a
3285 non-existent file that was broken.

3296PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3297 the use of a port name that isn't defined in /etc/services) occurred, the

3301 same time.

3333PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3334 that changes the way the GnuTLS parameters are stored in the cache file.
3335 The new format can be generated externally. For backward compatibility,
3336 if the data in the cache doesn't make sense, Exim assumes it has read an
3337 old-format file, and it generates new data and writes a new file. This
3338 means that you can't go back to an older release without removing the
3339 file.
3340
3341PH/03 A redirect router that has both "unseen" and "one_time" set does not
3342 work if there are any delivery delays because "one_time" forces the
3343 parent to be marked "delivered", so its unseen clone is never tried
3344 again. For this reason, Exim now forbids the simultaneous setting of
3345 these two options.

3350 consider the case when local delivery batching is involved. The test for
3351 "previously delivered" was not happening when checking to see if an
3352 address could be batched with a previous (undelivered) one; under
