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

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18 EXPERIMENTAL_CERTNAMES is withdrawn.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.

46Exim version 4.85
47-----------------
48TL/01 When running the test suite, the README says that variables such as
49 no_msglog_check are global and can be placed anywhere in a specific
50 test's script, however it was observed that placement needed to be near
51 the beginning for it to behave that way. Changed the runtest perl
52 script to read through the entire script once to detect and set these
53 variables, reset to the beginning of the script, and then run through
54 the script parsing/test process like normal.
55
ac20058f
TL
56TL/02 The BSD's have an arc4random API. One of the functions to induce
57 adding randomness was arc4random_stir(), but it has been removed in
58 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
59 function when detected.
60
a9b8ec8b
JH
61JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
62 cause callback expansion.
63
6286d7c4
TL
64TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
65 syntax errors in an expansion can be treated as a string instead of
66 logging or causing an error, due to the internal use of bool_lax
67 instead of bool when processing it.
68
0f06b4f2 69JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
70 server certificates when making smtp deliveries.
71
be36e572
JH
72JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
73

79 Merged patch from Sebastian Wiedenroth.
e449c3b0 80
bd21a787
WB
81JH/05 Fix results-pipe from transport process. Several recipients, combined
82 with certificate use, exposed issues where response data items split
83 over buffer boundaries were not parsed properly. This eventually
84 resulted in duplicates being sent. This issue only became common enough
85 to notice due to the introduction of conection certificate information,
86 the item size being so much larger. Found and fixed by Wolfgang Breyha.
87
8bc732e8
JH
88JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
89 size buffer was used, resulting in syntax errors when an expansion
90 exceeded it.
91
a7fec7a7
JH
92JH/07 Add support for directories of certificates when compiled with a GnuTLS
93 version 3.3.6 or later.
94
774ef2d7
JH
95JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
96 is EXPERIMENTAL_EVENT, the main-configuration and transport options
97 both become "event_action", the variables become $event_name, $event_data
aec45841 98 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
99 routers, transports and related events. The tls:cert event is now also
100 raised for inbound connections, if the main configuration event_action
101 option is defined.

eca4debb
TL
103TL/06 In test suite, disable OCSP for old versions of openssl which contained
104 early OCSP support, but no stapling (appears to be less than 1.0.0).
105
8d692470
JH
106JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
107 server certificate names available under the smtp transport option
108 "tls_verify_cert_hostname" now do not permit multi-component wildcard
109 matches.
110
e9477a08
JH
111JH/10 Time-related extraction expansions from certificates now use the main
112 option "timezone" setting for output formatting, and are consistent
113 between OpenSSL and GnuTLS compilations. Bug 1541.
114

116 encoded parameter in the incoming message. Bug 1558.

JH
117
118JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
119 include certificate info, eximon was claiming there were spoolfile
120 syntax errors.

155Exim version 4.83
156-----------------
157
158TF/01 Correctly close the server side of TLS when forking for delivery.
159
160 When a message was received over SMTP with TLS, Exim failed to clear up
161 the incoming connection properly after forking off the child process to
162 deliver the message. In some situations the subsequent outgoing
163 delivery connection happened to have the same fd number as the incoming
164 connection previously had. Exim would try to use TLS and fail, logging
165 a "Bad file descriptor" error.
166
7245734e
TF
167TF/02 Portability fix for building lookup modules on Solaris when the xpg4
168 utilities have not been installed.
169

170JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
171 temporary space as the ACL may create new global variables.

TL
173TL/01 LDAP support uses per connection or global context settings, depending
174 upon the detected version of the libraries at build time.

TL
176TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
177 to extract and use the src ip:port in logging and expansions as if it
8ded8589
TL
178 were a direct connection from the outside internet. PPv2 support was
179 updated based on HAProxy spec change in May 2014.

194
8ddef691 195TL/05 Rename SPF condition results err_perm and err_temp to standardized

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

224JH/12 Expand items in router/transport headers_add or headers_remove lists
225 individually rather than the list as a whole. Bug 1452.
226
227 Required for reasonable handling of multiple headers_ options when
228 they may be empty; requires that headers_remove items with embedded
229 colons must have them doubled (or the list-separator changed).

411TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
412
413 When a queue runner is handling a message, Exim first routes the
414 recipient addresses, during which it prunes them based on the retry
415 hints database. After that it attempts to deliver the message to
416 any remaining recipients. It then updates the hints database using
417 the retry rules.
418
419 So if a recipient address works intermittently, it can get repeatedly
420 deferred at routing time. The retry hints record remains fresh so the
421 address never reaches the final cutoff time.
422
423 This is a fairly common occurrence when a user is bumping up against
424 their storage quota. Exim had some logic in its local delivery code
425 to deal with this. However it did not apply to per-recipient defers
426 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
427
1ddeb334
TF
428 This change adds a proper retry rule check during routing so that the
429 final cutoff time is checked against the message's age. We only do
430 this check if there is an address retry record and there is not a
431 domain retry record; this implies that previous attempts to handle
432 the address had the retry_use_local_parts option turned on. We use
433 this as an approximation for the destination being like a local
434 delivery, as in LMTP.
67bd1ab3
TF
435
436 I suspect this new check makes the old local delivery cutoff check
437 redundant, but I have not verified this so I left the code in place.

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

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

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

759TF/03 Make the exiwhat support code safe for signals. Previously Exim might
760 lock up or crash if it happened to be inside a call to libc when it
761 got a SIGUSR1 from exiwhat.
762
763 The SIGUSR1 handler appends the current process status to the process
764 log which is later printed by exiwhat. It used to use the general
765 purpose logging code to do this, but several functions it calls are
766 not safe for signals.
767
768 The new output code in the SIGUSR1 handler is specific to the process
769 log, and simple enough that it's easy to inspect for signal safety.
770 Removing some special cases also simplifies the general logging code.
771 Removing the spurious timestamps from the process log simplifies
772 exiwhat.

TF
774TF/04 Improved ratelimit ACL condition.
775
776 The /noupdate option has been deprecated in favour of /readonly which
777 has clearer semantics. The /leaky, /strict, and /readonly update modes
778 are mutually exclusive. The update mode is no longer included in the
779 database key; it just determines when the database is updated. (This
780 means that when you upgrde Exim will forget old rate measurements.)
781
782 Exim now checks that the per_* options are used with an update mode that
783 makes sense for the current ACL. For example, when Exim is processing a
784 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
785 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
786 must specify per_mail/readonly. If you omit the update mode it defaults to
787 /leaky where that makes sense (as before) or /readonly where required.
788
789 The /noupdate option is now undocumented but still supported for
790 backwards compatibility. It is equivalent to /readonly except that in
791 ACLs where /readonly is required you may specify /leaky/noupdate or
792 /strict/noupdate which are treated the same as /readonly.
793
794 A useful new feature is the /count= option. This is a generalization
795 of the per_byte option, so that you can measure the throughput of other
796 aggregate values. For example, the per_byte option is now equivalent
797 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
798
799 The per_rcpt option has been generalized using the /count= mechanism
800 (though it's more complicated than the per_byte equivalence). When it is
801 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
802 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
803 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
804 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
805 Note that using per_rcpt with a non-readonly update mode in more than
806 one ACL will cause the recipients to be double-counted. (The per_mail
807 and per_byte options don't have this problem.)
808
809 The handling of very low rates has changed slightly. If the computed rate
810 is less than the event's count (usually one) then this event is the first
811 after a long gap. In this case the rate is set to the same as this event's
812 count, so that the first message of a spam run is counted properly.
813
814 The major new feature is a mechanism for counting the rate of unique
815 events. The new per_addr option counts the number of different
816 recipients that someone has sent messages to in the last time period. It
817 behaves like per_rcpt if all the recipient addresses are different, but
818 duplicate recipient addresses do not increase the measured rate. Like
819 the /count= option this is a general mechanism, so the per_addr option
820 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
821 example, measure the rate that a client uses different sender addresses
822 with the options per_mail/unique=$sender_address. There are further
823 details in the main documentation.

1374 were called 'true' and it seems that C99 defines that as a reserved

1376 not include C99-style headers which use bools without triggering

1395PH/01 Another patch from the Sieve maintainer.
1396
6a3bceb1
PH
1397PH/02 When an IPv6 address is converted to a string for single-key lookup
1398 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1399 dots are used instead of colons so that keys in lsearch files need not
1400 contain colons. This was done some time before quoting was made available
1401 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1402 (notated using the quote facility) so as to distinguish them from IPv4
1403 keys. This meant that lookups for IP addresses in host lists did not work
1404 for iplsearch lookups.
1405
1406 This has been fixed by arranging for IPv6 addresses to be expressed with
1407 colons if the lookup type is iplsearch. This is not incompatible, because
1408 previously such lookups could never work.
1409
1410 The situation is now rather anomolous, since one *can* have colons in
1411 ordinary lsearch keys. However, making the change in all cases is
1412 incompatible and would probably break a number of configurations.

1417MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1418 conversion specification without a maximum field width, thereby enabling
1419 a rogue spamd server to cause a buffer overflow. While nobody in their
1420 right mind would setup Exim to query an untrusted spamd server, an
1421 attacker that gains access to a server running spamd could potentially
1422 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1427MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1428 a directory entry by the name of the lookup key. Previously, if a
1429 symlink pointed to a non-existing file or a file in a directory that
1430 Exim lacked permissions to read, a lookup for a key matching that
1431 symlink would fail. Now it is enough that a matching directory entry
1432 exists, symlink or not. (Bugzilla 503.)

PH
1615PH/29 SMTP synchronization checks are implemented when a command is read -
1616 there is a check that no more input is waiting when there shouldn't be
1617 any. However, for some commands, a delay in an ACL can mean that it is
1618 some time before the response is written. In this time, more input might
1619 arrive, invalidly. So now there are extra checks after an ACL has run for
1620 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1621 pipelining has not been advertised.

PH
1695 the response to the final '.' that terminates a message, but only in the
1696 case where the client has not sent further data following the '.'
1697 (unfortunately, this is allowed). However, in many cases there won't be
1698 any further data because there won't be any more messages to send. A call
1699 to select() can be used: if it shows that the input is "ready", there is
1700 either input waiting, or the socket has been closed. An attempt to read
1701 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1702 would have sent an OK response which the client would never have see.

1713PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1714 fixed by 4.65/MH/01 (is this a record?) are fixed:
1715
1716 (i) An empty string was always treated as zero by the numeric comparison
1717 operators. This behaviour has been restored.
1718
1719 (ii) It is documented that the numeric comparison operators always treat
1720 their arguments as decimal numbers. This was broken in that numbers
1721 starting with 0 were being interpreted as octal.
1722
1723 While fixing these problems I realized that there was another issue that
1724 hadn't been noticed. Values of message_size_limit (both the global option
1725 and the transport option) were treated as octal if they started with 0.
1726 The documentation was vague. These values are now always treated as
1727 decimal, and I will make that clear in the documentation.

1744 large number of recipients for a single message is ridiculous
1745 (performance will be very, very poor), I have chosen to impose a limit
1746 rather than extend the field.

2b1c6e3a
PH
1771PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1772 callout verification, Exim cached a "reject" for the entire domain. This
1773 is correct for most verifications, but it is not correct for a recipient
1774 verification with use_sender or use_postmaster set, because in that case
1775 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1776 case of MAIL FROM:<> rejection from other early rejections (e.g.
1777 rejection of HELO). When verifying a recipient using a non-null MAIL
1778 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1779 Whatever the result of the callout, the value of the domain cache is
1780 left unchanged (for any other kind of callout, getting as far as trying
1781 RCPT means that the domain itself is ok).

1815PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1817 probably the interface on which it is arriving) and not to the outgoing
1818 callout (which could be using a different interface). This has been
1819 changed to use the value of the helo_data option from the smtp transport
1820 instead - this is what is used when a message is actually being sent. If
1821 there is no remote transport (possible with a router that sets up host
1822 addresses), $smtp_active_hostname is used.

7befa435 1825 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1826 (a) The code assumed that strncpy() returns a negative number on buffer
1827 overflow, which isn't the case. Replaced with Exim's string_format()
1828 function.
1829 (b) There were several signed/unsigned issues. I just did the minimum
1830 hacking in of casts. There is scope for a larger refactoring.
1831 (c) The code used strcasecmp() which is not a standard C function.
1832 Replaced with Exim's strcmpic() function.
1833 (d) The code set only $1; it now sets $auth1 as well.
1834 (e) A simple test gave the error "authentication client didn't specify
1835 service in request". It would seem that Dovecot has changed its
1836 interface. Fortunately there's a specification; I followed it and
1837 changed what the client sends and it appears to be working now.

1843 address A is aliased to B and C, where B exists and C does not. Without
1844 -v the output is "A verified" because verification stops after a
1845 successful redirection if more than one address is generated. However,
1846 with -v the child addresses are also verified. Exim was outputting "A
1847 failed to verify" and then showing the successful verification for C,
1848 with its parentage. It now outputs "B failed to verify", showing B's
1849 parentage before showing the successful verification of C.

1854
322050c2
PH
1855PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1856 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1857 they consult the DNS. I had assumed they would set it the way they
1858 wanted; and indeed my experiments on Linux seem to show that in some
1859 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1860 To be on the safe side, however, I have now made the interface to
1861 host_find_byname() similar to host_find_bydns(), with an argument
1862 containing the DNS resolver options. The host_find_byname() function now
1863 sets these options at its start, just as host_find_bydns() does. The smtp
1864 transport options dns_qualify_single and dns_search_parents are passed to
1865 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1866 of host_find_byname() use the default settings of RES_DEFNAMES
1867 (qualify_single) but not RES_DNSRCH (search_parents).

1869PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1870 spool_read_header() do less string testing, by means of a preliminary
1871 switch on the second character of optional "-foo" lines. (This is
1872 overdue, caused by the large number of possibilities that now exist.
1873 Originally there were few.) While I was there, I also converted the
1874 str(n)cmp tests so they don't re-test the leading "-" and the first
1875 character, in the hope this might squeeze out yet more improvement.

PH
1877PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1878 flag allowing group syntax was set by the header_syntax check but not
1879 turned off, possible causing trouble later; (2) The flag was not being
1880 set at all for the header_verify test, causing "group"-style headers to
1881 be rejected. I have now set it in this case, and also caused header_
1882 verify to ignore an empty address taken from a group. While doing this, I
1883 came across some other cases where the code for allowing group syntax
1884 while scanning a header line wasn't quite right (mostly, not resetting
1885 the flag correctly in the right place). These bugs could have caused
1886 trouble for malformed header lines. I hope it is now all correct.

PH
1888PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1889 with the "reply" argument non-NULL. The code, however (which originally
1890 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1891 but it didn't always do it. This confused somebody who was copying the
1892 code for some other use. I have removed all the tests.

PH
1894PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1895 feature that was used to support insecure browsers during the U.S. crypto
1896 embargo. It requires special client support, and Exim is probably the
1897 only MTA that supported it -- and would never use it because real RSA is
1898 always available. This code has been removed, because it had the bad
1899 effect of slowing Exim down by computing (never used) parameters for the
1900 RSA_EXPORT functionality.

1905 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1906 if the connection is using TLS or if the remote IP is the same as the
1907 local IP, and the "valid-client-cert option" if a client certificate has
1908 been verified.

PH
1939
1940PH/30 Exim was sometimes attempting to deliver messages that had suffered
1941 address errors (4xx response to RCPT) over the same connection as other
1942 messages routed to the same hosts. Such deliveries are always "forced",
1943 so retry times are not inspected. This resulted in far too many retries
1944 for the affected addresses. The effect occurred only when there were more
1945 hosts than the hosts_max_try setting in the smtp transport when it had
1946 the 4xx errors. Those hosts that it had tried were not added to the list
1947 of hosts for which the message was waiting, so if all were tried, there
1948 was no problem. Two fixes have been applied:
1949
1950 (i) If there are any address or message errors in an SMTP delivery, none
1951 of the hosts (tried or untried) are now added to the list of hosts
1952 for which the message is waiting, so the message should not be a
1953 candidate for sending over the same connection that was used for a
1954 successful delivery of some other message. This seems entirely
1955 reasonable: after all the message is NOT "waiting for some host".
1956 This is so "obvious" that I'm not sure why it wasn't done
1957 previously. Hope I haven't missed anything, but it can't do any
1958 harm, as the worst effect is to miss an optimization.
1959

1978 written to the panic log as well as the main log, but it isn't really

1983PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1984 runs only) independently of the message's sender address. This meant
1985 that, if the 4xx error was in fact related to the sender, a different
1986 message to the same recipient with a different sender could confuse
1987 things. In particualar, this can happen when sending to a greylisting
1988 server, but other circumstances could also provoke similar problems.
1989 I have changed the default so that the retry time for these errors is now
1990 based a combination of the sender and recipient addresses. This change
1991 can be overridden by setting address_retry_include_sender=false in the
1992 smtp transport.

2263 tcp-wrappers gives "deny", whereas what one would like would be some
2264 kind of temporary error. A kludge has been added to help with this.
2265 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2266 554 error is used if errno is still zero or contains ENOENT (which occurs
2267 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2373 non-existent - all you got was a failure to exec. I have made two
2374 changes:
2375
2376 (a) Failures to set uid/gid, the current directory, or a process leader
2377 in a subprocess such as that created by queryprogram now generate
2378 suitable debugging ouput when -d is set.

2387PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2388 additional section of a DNS packet that returns MX or SRV records.
2389 Instead, it always explicitly searches for A/AAAA records. This avoids
2390 major problems that occur when a DNS server includes only records of one
2391 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2392 fixed another bug: if SRV records were looked up and the corresponding
2393 address records were *not* found in the additional section, the port
2394 values from the SRV records were lost.

PH
2404PH/19 When calculating a retry time, Exim used to measure the "time since
2405 failure" by looking at the "first failed" field in the retry record. Now
2406 it does not use this if it is later than than the arrival time of the
2407 message. Instead it uses the arrival time. This makes for better
2408 behaviour in cases where some deliveries succeed, thus re-setting the
2409 "first failed" field. An example is a quota failure for a huge message
2410 when small messages continue to be delivered. Without this change, the
2411 "time since failure" will always be short, possible causing more frequent
2412 delivery attempts for the huge message than are intended.

2509PH/42 The content-scanning code uses fopen() to create files in which to put
2510 message data. Previously it was not paying any attention to the mode of
2511 the files. Exim runs with umask(0) because the rest of the code creates
2512 files with open(), and sets the required mode explicitly. Thus, these
2513 files were ending up world-writeable. This was not a big issue, because,
2514 being within the spool directory, they were not world-accessible. I have
2515 created a function called modefopen, which takes an additional mode
2516 argument. It sets umask(777), creates the file, chmods it to the required
2517 mode, then resets the umask. All the relevant calls to fopen() in the

2554 used in LMTP mode:
2555
2556 (i) Exim was not creating retry information for temporary errors given
2557 for individual recipients after the DATA command when the smtp transport
2558 was used in LMTP mode. This meant that they could be retried too
2559 frequently, and not timed out correctly.
2560
2561 (ii) Exim was setting the flag that allows error details to be returned
2562 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2563 recipients that were returned after the DATA command.
2564
2565PH/53 This is related to PH/52, but is more general: for any failing address,
2566 when detailed error information was permitted to be returned to the
2567 sender, but the error was temporary, then after the final timeout, only
2568 "retry timeout exceeded" was returned. Now it returns the full error as

2640 function verify_get_ident() calls ip_connect() to connect a socket, but
2641 if the "connect()" function timed out, ip_connect() used to close the
2642 socket. However, verify_get_ident() also closes the socket later, and in
2643 between Exim writes to the log, which may get opened at this point. When
2644 the socket was closed in ip_connect(), the log could get the same file
2645 descriptor number as the socket. This naturally causes chaos. The fix is
2646 not to close the socket in ip_connect(); the socket should be closed by
2647 the function that creates it. There was only one place in the code where
2648 this was missing, in the iplookup router, which I don't think anybody now
2649 uses, but I've fixed it anyway.

2711 Received: from [1.2.3.4] (helo=[1.2.3.4])

2756 The auto-replied keyword:
2757
2758 - SHOULD be used on messages sent in direct response to another
2759 message by an automatic process,
2760

2762
2763 - MAY be used on Delivery Status Notifications (DSNs) and Message
2764 Disposition Notifications (MDNs),

2766 - MUST NOT be used on messages generated by automatic or periodic
2767 processes, except for messages which are automatic responses to
2768 other messages.

PH
2804PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2805 canonical form (as documented). However, after a host name lookup from
2806 the IP address, check_host() was doing a simple string comparison with
2807 addresses acquired from the DNS when checking that the found name did
2808 have the original IP as one of its addresses. Since any found IPv6
2809 addresses are likely to be in abbreviated form, the comparison could
2810 fail. Luckily, there already exists a function for doing the comparison
2811 by converting both addresses to binary, so now that is used instead of
2812 the text comparison.
2813

PH
2814PH/20 There was another similar case to PH/19, when a complete host name was

3112 preserve the sysexits.h value, by assumimg that macro definitions were

3152 message has one envelope recipient. SA can use these headers,
3153 obviously out-of-the-box. Patch from Alex Miller.

3155PH/08 The ${def test on a variable was returning false if the variable's
3156 value was "0", contrary to what the specification has always said!
3157 The result should be true unless the variable is empty.
3158
3159PH/09 The syntax error of a character other than { following "${if
3160 def:variable_name" (after optional whitespace) was not being diagnosed.
3161 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3162 accidental colon was present, for example, could give incorrect results.

3166 to be made).
3167
3168PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
3169 This involved changing a lot of size variables from int to off_t. It
3170 should work with maildirs and everything.

3187PH/15 The code I had for printing potentially long long variables in PH/11

3190 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3191 to be "long long int" or "long int". This is needed for the internal
3192 formatting function string_vformat().

3194PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3195 the configuration file to be ":syslog", then the script "guesses" where
3196 the logs files are, rather than using the compiled in default. In our
3197 case the guess is not the same as the compiled default, so the script
3198 suddenly stopped working when I started to use syslog. The patch checks
3199 to see if log_file_path is "". If so, it attempts to read it from exim
3200 with no configuration file to get the compiled in version, before it
3201 falls back to the previous guessing code."

3218 and a new error check for 8bit text in MIME parts. Comparator and

3244PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3245 databases so that it will be absolutely obvious if a crash occurs in the

3250 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3251 picked up on a user's system that detects such things. There doesn't seem
3252 to be a gcc warning option for this - only an attribute that has to be
3253 put on the function's prototype. It seems that in Fedora Core 4 they have
3254 set this on a number of new functions. No doubt there will be more in due
3255 course.

PH
3257PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3258 specify a transport. However, if an address that was verified by such a
3259 router was the subject of a callout, Exim crashed because it tried to
3260 read the rcpt_include_affixes from the non-existent transport. Now it
3261 just assumes that the setting of that option is false. This bug was
3262 introduced by 4.51/PH/31.

3272PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3273 aren't the modern standard, and it seems that some systems' include files
3274 don't always have them. Exim was already checking for some of the newer
3275 ones like T_AAAA, and defining it itself. I've added checks for all the
3276 record types that Exim uses.

3278PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3279 not automatically generating a new one, as it is supposed to. This
3280 prevented TLS from working. If the file did exist, but contained invalid
3281 data, a new version was generated, as expected. It was only the case of a
3282 non-existent file that was broken.

3294 the use of a port name that isn't defined in /etc/services) occurred, the

3296 spool, instead of being failed because of the mua_wrapper setting. This
3297 is now fixed, and I tidied up some of the mua_wrapper messages at the
3298 same time.

3329
3330PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3331 that changes the way the GnuTLS parameters are stored in the cache file.
3332 The new format can be generated externally. For backward compatibility,
3333 if the data in the cache doesn't make sense, Exim assumes it has read an
3334 old-format file, and it generates new data and writes a new file. This
3335 means that you can't go back to an older release without removing the
3336 file.
3337
3338PH/03 A redirect router that has both "unseen" and "one_time" set does not
3339 work if there are any delivery delays because "one_time" forces the
3340 parent to be marked "delivered", so its unseen clone is never tried
3341 again. For this reason, Exim now forbids the simultaneous setting of
3342 these two options.
3343
3344PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3345 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3346 entry if you want to know the details. The fix, however, neglected to
3347 consider the case when local delivery batching is involved. The test for
3348 "previously delivered" was not happening when checking to see if an
3349 address could be batched with a previous (undelivered) one; under
3350 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3351 address.
