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18 EXPERIMENTAL_CERTNAMES is withdrawn.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

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
23763898 40 the options can now be changed in the usual way. Bug 68.

56JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
57 now supports optional time-restrictions, weighting, and backup-only
58 modifiers per server. Patch originally by <rommer@active.by>.
59
60JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
61 and remote servers. Remote servers can be IPv6 addresses, and
62 specify a port-range.

69Exim version 4.85
70-----------------
71TL/01 When running the test suite, the README says that variables such as
72 no_msglog_check are global and can be placed anywhere in a specific
73 test's script, however it was observed that placement needed to be near
74 the beginning for it to behave that way. Changed the runtest perl
75 script to read through the entire script once to detect and set these
76 variables, reset to the beginning of the script, and then run through
77 the script parsing/test process like normal.
78
ac20058f
TL
79TL/02 The BSD's have an arc4random API. One of the functions to induce
80 adding randomness was arc4random_stir(), but it has been removed in
81 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
82 function when detected.
83
a9b8ec8b
JH
84JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
85 cause callback expansion.
86
6286d7c4
TL
87TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
88 syntax errors in an expansion can be treated as a string instead of
89 logging or causing an error, due to the internal use of bool_lax
90 instead of bool when processing it.
91
0f06b4f2 92JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
93 server certificates when making smtp deliveries.

WB
104JH/05 Fix results-pipe from transport process. Several recipients, combined
105 with certificate use, exposed issues where response data items split
106 over buffer boundaries were not parsed properly. This eventually
107 resulted in duplicates being sent. This issue only became common enough
108 to notice due to the introduction of conection certificate information,
109 the item size being so much larger. Found and fixed by Wolfgang Breyha.
110
8bc732e8
JH
111JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
112 size buffer was used, resulting in syntax errors when an expansion
113 exceeded it.
114
a7fec7a7
JH
115JH/07 Add support for directories of certificates when compiled with a GnuTLS
116 version 3.3.6 or later.
117
774ef2d7
JH
118JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
119 is EXPERIMENTAL_EVENT, the main-configuration and transport options
120 both become "event_action", the variables become $event_name, $event_data
aec45841 121 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
122 routers, transports and related events. The tls:cert event is now also
123 raised for inbound connections, if the main configuration event_action
124 option is defined.

eca4debb
TL
126TL/06 In test suite, disable OCSP for old versions of openssl which contained
127 early OCSP support, but no stapling (appears to be less than 1.0.0).
128
8d692470
JH
129JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
130 server certificate names available under the smtp transport option
131 "tls_verify_cert_hostname" now do not permit multi-component wildcard
132 matches.
133
e9477a08
JH
134JH/10 Time-related extraction expansions from certificates now use the main
135 option "timezone" setting for output formatting, and are consistent
136 between OpenSSL and GnuTLS compilations. Bug 1541.
137
ad4c5ff9

138JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
139 encoded parameter in the incoming message. Bug 1558.

140
141JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
142 include certificate info, eximon was claiming there were spoolfile
143 syntax errors.

178Exim version 4.83
179-----------------
180
181TF/01 Correctly close the server side of TLS when forking for delivery.
182
183 When a message was received over SMTP with TLS, Exim failed to clear up
184 the incoming connection properly after forking off the child process to
185 deliver the message. In some situations the subsequent outgoing
186 delivery connection happened to have the same fd number as the incoming
187 connection previously had. Exim would try to use TLS and fail, logging
188 a "Bad file descriptor" error.

190TF/02 Portability fix for building lookup modules on Solaris when the xpg4
191 utilities have not been installed.

220 still accepted. In a future release, err_perm and err_temp will be
221 completely removed, which will be a backward incompatibility if the

434TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
435
436 When a queue runner is handling a message, Exim first routes the
437 recipient addresses, during which it prunes them based on the retry
438 hints database. After that it attempts to deliver the message to
439 any remaining recipients. It then updates the hints database using
440 the retry rules.
441
442 So if a recipient address works intermittently, it can get repeatedly
443 deferred at routing time. The retry hints record remains fresh so the
444 address never reaches the final cutoff time.
445
446 This is a fairly common occurrence when a user is bumping up against
447 their storage quota. Exim had some logic in its local delivery code
448 to deal with this. However it did not apply to per-recipient defers
449 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
450
1ddeb334
TF
451 This change adds a proper retry rule check during routing so that the
452 final cutoff time is checked against the message's age. We only do
453 this check if there is an address retry record and there is not a
454 domain retry record; this implies that previous attempts to handle
455 the address had the retry_use_local_parts option turned on. We use
456 this as an approximation for the destination being like a local
457 delivery, as in LMTP.
67bd1ab3
TF
458
459 I suspect this new check makes the old local delivery cutoff check
460 redundant, but I have not verified this so I left the code in place.

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

499 acl_data_smtp_prdr ACL is called once for each recipient, after
500 the body content is received and before the acl_smtp_data ACL.
501 The client is controlled by bolth of: a hosts_try_prdr option
502 on the smtp transport, and the server advertisement.
503 Default client logging of deliveries and rejections involving
504 PRDR are flagged with the string "PRDR".

782TF/03 Make the exiwhat support code safe for signals. Previously Exim might
783 lock up or crash if it happened to be inside a call to libc when it
784 got a SIGUSR1 from exiwhat.
785
786 The SIGUSR1 handler appends the current process status to the process
787 log which is later printed by exiwhat. It used to use the general
788 purpose logging code to do this, but several functions it calls are
789 not safe for signals.
790
791 The new output code in the SIGUSR1 handler is specific to the process
792 log, and simple enough that it's easy to inspect for signal safety.
793 Removing some special cases also simplifies the general logging code.
794 Removing the spurious timestamps from the process log simplifies
795 exiwhat.

TF
797TF/04 Improved ratelimit ACL condition.
798
799 The /noupdate option has been deprecated in favour of /readonly which
800 has clearer semantics. The /leaky, /strict, and /readonly update modes
801 are mutually exclusive. The update mode is no longer included in the
802 database key; it just determines when the database is updated. (This
803 means that when you upgrde Exim will forget old rate measurements.)
804
805 Exim now checks that the per_* options are used with an update mode that
806 makes sense for the current ACL. For example, when Exim is processing a
807 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
808 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
809 must specify per_mail/readonly. If you omit the update mode it defaults to
810 /leaky where that makes sense (as before) or /readonly where required.
811
812 The /noupdate option is now undocumented but still supported for
813 backwards compatibility. It is equivalent to /readonly except that in
814 ACLs where /readonly is required you may specify /leaky/noupdate or
815 /strict/noupdate which are treated the same as /readonly.
816
817 A useful new feature is the /count= option. This is a generalization
818 of the per_byte option, so that you can measure the throughput of other
819 aggregate values. For example, the per_byte option is now equivalent
820 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
821
822 The per_rcpt option has been generalized using the /count= mechanism
823 (though it's more complicated than the per_byte equivalence). When it is
824 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
825 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
826 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
827 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
828 Note that using per_rcpt with a non-readonly update mode in more than
829 one ACL will cause the recipients to be double-counted. (The per_mail
830 and per_byte options don't have this problem.)
831
832 The handling of very low rates has changed slightly. If the computed rate
833 is less than the event's count (usually one) then this event is the first
834 after a long gap. In this case the rate is set to the same as this event's
835 count, so that the first message of a spam run is counted properly.
836
837 The major new feature is a mechanism for counting the rate of unique
838 events. The new per_addr option counts the number of different
839 recipients that someone has sent messages to in the last time period. It
840 behaves like per_rcpt if all the recipient addresses are different, but
841 duplicate recipient addresses do not increase the measured rate. Like
842 the /count= option this is a general mechanism, so the per_addr option
843 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
844 example, measure the rate that a client uses different sender addresses
845 with the options per_mail/unique=$sender_address. There are further
846 details in the main documentation.

1397 were called 'true' and it seems that C99 defines that as a reserved

1399 not include C99-style headers which use bools without triggering

1419
6a3bceb1
PH
1420PH/02 When an IPv6 address is converted to a string for single-key lookup
1421 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1422 dots are used instead of colons so that keys in lsearch files need not
1423 contain colons. This was done some time before quoting was made available
1424 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1425 (notated using the quote facility) so as to distinguish them from IPv4
1426 keys. This meant that lookups for IP addresses in host lists did not work
1427 for iplsearch lookups.
1428
1429 This has been fixed by arranging for IPv6 addresses to be expressed with
1430 colons if the lookup type is iplsearch. This is not incompatible, because
1431 previously such lookups could never work.
1432
1433 The situation is now rather anomolous, since one *can* have colons in
1434 ordinary lsearch keys. However, making the change in all cases is
1435 incompatible and would probably break a number of configurations.

1440MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1441 conversion specification without a maximum field width, thereby enabling
1442 a rogue spamd server to cause a buffer overflow. While nobody in their
1443 right mind would setup Exim to query an untrusted spamd server, an
1444 attacker that gains access to a server running spamd could potentially
1445 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1450MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1451 a directory entry by the name of the lookup key. Previously, if a
1452 symlink pointed to a non-existing file or a file in a directory that
1453 Exim lacked permissions to read, a lookup for a key matching that
1454 symlink would fail. Now it is enough that a matching directory entry
1455 exists, symlink or not. (Bugzilla 503.)

PH
1638PH/29 SMTP synchronization checks are implemented when a command is read -
1639 there is a check that no more input is waiting when there shouldn't be
1640 any. However, for some commands, a delay in an ACL can mean that it is
1641 some time before the response is written. In this time, more input might
1642 arrive, invalidly. So now there are extra checks after an ACL has run for
1643 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1644 pipelining has not been advertised.

1659 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1660 was a macro that became an assignment, so it seemed to work. This has

1693 started the daemon, but after a SIGHUP it used the Exim user (because it
1694 calls itself on a restart). I have changed the code so that it now always
1695 uses the Exim user.

1700 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1718 the response to the final '.' that terminates a message, but only in the
1719 case where the client has not sent further data following the '.'
1720 (unfortunately, this is allowed). However, in many cases there won't be
1721 any further data because there won't be any more messages to send. A call
1722 to select() can be used: if it shows that the input is "ready", there is
1723 either input waiting, or the socket has been closed. An attempt to read
1724 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1725 would have sent an OK response which the client would never have see.

1735
1736PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1737 fixed by 4.65/MH/01 (is this a record?) are fixed:
1738
1739 (i) An empty string was always treated as zero by the numeric comparison
1740 operators. This behaviour has been restored.
1741
1742 (ii) It is documented that the numeric comparison operators always treat
1743 their arguments as decimal numbers. This was broken in that numbers
1744 starting with 0 were being interpreted as octal.
1745
1746 While fixing these problems I realized that there was another issue that
1747 hadn't been noticed. Values of message_size_limit (both the global option
1748 and the transport option) were treated as octal if they started with 0.
1749 The documentation was vague. These values are now always treated as
1750 decimal, and I will make that clear in the documentation.

1764PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1765 child addresses, Exim now panics and dies. Previously, because the count
1766 is held in a short int, deliveries were likely to be lost. As such a
1767 large number of recipients for a single message is ridiculous
1768 (performance will be very, very poor), I have chosen to impose a limit
1769 rather than extend the field.

1775TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1776 leftover -K file (the existence of which was triggered by #402).

1784
1785TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1794PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1795 callout verification, Exim cached a "reject" for the entire domain. This
1796 is correct for most verifications, but it is not correct for a recipient
1797 verification with use_sender or use_postmaster set, because in that case
1798 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1799 case of MAIL FROM:<> rejection from other early rejections (e.g.
1800 rejection of HELO). When verifying a recipient using a non-null MAIL
1801 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1802 Whatever the result of the callout, the value of the domain cache is
1803 left unchanged (for any other kind of callout, getting as far as trying
1804 RCPT means that the domain itself is ok).

1838PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1839 hostname. This is wrong, because it relates to the incoming message (and
1840 probably the interface on which it is arriving) and not to the outgoing
1841 callout (which could be using a different interface). This has been
1842 changed to use the value of the helo_data option from the smtp transport
1843 instead - this is what is used when a message is actually being sent. If
1844 there is no remote transport (possible with a router that sets up host
1845 addresses), $smtp_active_hostname is used.

14aa5a05 1847PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1848 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1849 (a) The code assumed that strncpy() returns a negative number on buffer
1850 overflow, which isn't the case. Replaced with Exim's string_format()
1851 function.
1852 (b) There were several signed/unsigned issues. I just did the minimum
1853 hacking in of casts. There is scope for a larger refactoring.
1854 (c) The code used strcasecmp() which is not a standard C function.
1855 Replaced with Exim's strcmpic() function.
1856 (d) The code set only $1; it now sets $auth1 as well.
1857 (e) A simple test gave the error "authentication client didn't specify
1858 service in request". It would seem that Dovecot has changed its
1859 interface. Fortunately there's a specification; I followed it and
1860 changed what the client sends and it appears to be working now.

1865PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1866 address A is aliased to B and C, where B exists and C does not. Without
1867 -v the output is "A verified" because verification stops after a
1868 successful redirection if more than one address is generated. However,
1869 with -v the child addresses are also verified. Exim was outputting "A
1870 failed to verify" and then showing the successful verification for C,
1871 with its parentage. It now outputs "B failed to verify", showing B's
1872 parentage before showing the successful verification of C.

1875 look up a TXT record in a specific list after matching in a combined
1876 list.
1877
322050c2
PH
1878PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1879 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1880 they consult the DNS. I had assumed they would set it the way they
1881 wanted; and indeed my experiments on Linux seem to show that in some
1882 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1883 To be on the safe side, however, I have now made the interface to
1884 host_find_byname() similar to host_find_bydns(), with an argument
1885 containing the DNS resolver options. The host_find_byname() function now
1886 sets these options at its start, just as host_find_bydns() does. The smtp
1887 transport options dns_qualify_single and dns_search_parents are passed to
1888 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1889 of host_find_byname() use the default settings of RES_DEFNAMES
1890 (qualify_single) but not RES_DNSRCH (search_parents).

1892PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1893 spool_read_header() do less string testing, by means of a preliminary
1894 switch on the second character of optional "-foo" lines. (This is
1895 overdue, caused by the large number of possibilities that now exist.
1896 Originally there were few.) While I was there, I also converted the
1897 str(n)cmp tests so they don't re-test the leading "-" and the first
1898 character, in the hope this might squeeze out yet more improvement.

PH
1900PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1901 flag allowing group syntax was set by the header_syntax check but not
1902 turned off, possible causing trouble later; (2) The flag was not being
1903 set at all for the header_verify test, causing "group"-style headers to
1904 be rejected. I have now set it in this case, and also caused header_
1905 verify to ignore an empty address taken from a group. While doing this, I
1906 came across some other cases where the code for allowing group syntax
1907 while scanning a header line wasn't quite right (mostly, not resetting
1908 the flag correctly in the right place). These bugs could have caused
1909 trouble for malformed header lines. I hope it is now all correct.

PH
1911PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1912 with the "reply" argument non-NULL. The code, however (which originally
1913 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1914 but it didn't always do it. This confused somebody who was copying the
1915 code for some other use. I have removed all the tests.

PH
1917PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1918 feature that was used to support insecure browsers during the U.S. crypto
1919 embargo. It requires special client support, and Exim is probably the
1920 only MTA that supported it -- and would never use it because real RSA is
1921 always available. This code has been removed, because it had the bad
1922 effect of slowing Exim down by computing (never used) parameters for the
1923 RSA_EXPORT functionality.

1928 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1929 if the connection is using TLS or if the remote IP is the same as the
1930 local IP, and the "valid-client-cert option" if a client certificate has
1931 been verified.

1963PH/30 Exim was sometimes attempting to deliver messages that had suffered
1964 address errors (4xx response to RCPT) over the same connection as other
1965 messages routed to the same hosts. Such deliveries are always "forced",
1966 so retry times are not inspected. This resulted in far too many retries
1967 for the affected addresses. The effect occurred only when there were more
1968 hosts than the hosts_max_try setting in the smtp transport when it had
1969 the 4xx errors. Those hosts that it had tried were not added to the list
1970 of hosts for which the message was waiting, so if all were tried, there
1971 was no problem. Two fixes have been applied:
1972
1973 (i) If there are any address or message errors in an SMTP delivery, none
1974 of the hosts (tried or untried) are now added to the list of hosts
1975 for which the message is waiting, so the message should not be a
1976 candidate for sending over the same connection that was used for a
1977 successful delivery of some other message. This seems entirely
1978 reasonable: after all the message is NOT "waiting for some host".
1979 This is so "obvious" that I'm not sure why it wasn't done
1980 previously. Hope I haven't missed anything, but it can't do any
1981 harm, as the worst effect is to miss an optimization.
1982
1983 (ii) If, despite (i), such a delivery is accidentally attempted, the
1984 routing retry time is respected, so at least it doesn't keep
1985 hammering the server.

2000PH/35 The error "getsockname() failed: connection reset by peer" was being
2001 written to the panic log as well as the main log, but it isn't really
2002 panic-worthy as it just means the connection died rather early on. I have
2003 removed the panic log writing for the ECONNRESET error when getsockname()
2004 fails.

48c7f9e2
PH
2006PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2007 runs only) independently of the message's sender address. This meant
2008 that, if the 4xx error was in fact related to the sender, a different
2009 message to the same recipient with a different sender could confuse
2010 things. In particualar, this can happen when sending to a greylisting
2011 server, but other circumstances could also provoke similar problems.
2012 I have changed the default so that the retry time for these errors is now
2013 based a combination of the sender and recipient addresses. This change
2014 can be overridden by setting address_retry_include_sender=false in the
2015 smtp transport.

2286 tcp-wrappers gives "deny", whereas what one would like would be some
2287 kind of temporary error. A kludge has been added to help with this.
2288 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2289 554 error is used if errno is still zero or contains ENOENT (which occurs
2290 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2376 autoreply, Exim could try to deliver to a non-existent relative file

2378 it logs this as a hard delivery error, but does not attempt to create a

2400 in a subprocess such as that created by queryprogram now generate
2401 suitable debugging ouput when -d is set.

2410PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2411 additional section of a DNS packet that returns MX or SRV records.
2412 Instead, it always explicitly searches for A/AAAA records. This avoids
2413 major problems that occur when a DNS server includes only records of one
2414 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2415 fixed another bug: if SRV records were looked up and the corresponding
2416 address records were *not* found in the additional section, the port
2417 values from the SRV records were lost.

PH
2427PH/19 When calculating a retry time, Exim used to measure the "time since
2428 failure" by looking at the "first failed" field in the retry record. Now
2429 it does not use this if it is later than than the arrival time of the
2430 message. Instead it uses the arrival time. This makes for better
2431 behaviour in cases where some deliveries succeed, thus re-setting the
2432 "first failed" field. An example is a quota failure for a huge message
2433 when small messages continue to be delivered. Without this change, the
2434 "time since failure" will always be short, possible causing more frequent
2435 delivery attempts for the huge message than are intended.

PH
2532PH/42 The content-scanning code uses fopen() to create files in which to put
2533 message data. Previously it was not paying any attention to the mode of
2534 the files. Exim runs with umask(0) because the rest of the code creates
2535 files with open(), and sets the required mode explicitly. Thus, these
2536 files were ending up world-writeable. This was not a big issue, because,
2537 being within the spool directory, they were not world-accessible. I have
2538 created a function called modefopen, which takes an additional mode
2539 argument. It sets umask(777), creates the file, chmods it to the required
2540 mode, then resets the umask. All the relevant calls to fopen() in the
2541 content scanning code have been changed to use this function.

2578
2579 (i) Exim was not creating retry information for temporary errors given
2580 for individual recipients after the DATA command when the smtp transport
2581 was used in LMTP mode. This meant that they could be retried too
2582 frequently, and not timed out correctly.
2583
2584 (ii) Exim was setting the flag that allows error details to be returned
2585 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2586 recipients that were returned after the DATA command.
2587
2588PH/53 This is related to PH/52, but is more general: for any failing address,
2589 when detailed error information was permitted to be returned to the
2590 sender, but the error was temporary, then after the final timeout, only
2591 "retry timeout exceeded" was returned. Now it returns the full error as

2662PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2663 function verify_get_ident() calls ip_connect() to connect a socket, but
2664 if the "connect()" function timed out, ip_connect() used to close the
2665 socket. However, verify_get_ident() also closes the socket later, and in
2666 between Exim writes to the log, which may get opened at this point. When
2667 the socket was closed in ip_connect(), the log could get the same file
2668 descriptor number as the socket. This naturally causes chaos. The fix is
2669 not to close the socket in ip_connect(); the socket should be closed by
2670 the function that creates it. There was only one place in the code where
2671 this was missing, in the iplookup router, which I don't think anybody now
2672 uses, but I've fixed it anyway.

2733
2734 Received: from [1.2.3.4] (helo=[1.2.3.4])

2764PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2765 Electronic Mail") by including:
2766
2767 Auto-submitted: auto-generated
2768
2769 in the messages that it generates (bounce messages and others, such as
2770 warnings). In the case of bounce messages for non-SMTP mesages, there was
2771 also a typo: it was using "Auto_submitted" (underscore instead of
2772 hyphen). Since every message generated by Exim is necessarily in response
2773 to another message, thes have all been changed to:
2774
2775 Auto-Submitted: auto-replied
2776
2777 in accordance with these statements in the RFC:
2778
2779 The auto-replied keyword:
2780
2781 - SHOULD be used on messages sent in direct response to another
2782 message by an automatic process,
2783
2784 - MUST NOT be used on manually-generated messages,
2785
2786 - MAY be used on Delivery Status Notifications (DSNs) and Message
2787 Disposition Notifications (MDNs),
2788
2789 - MUST NOT be used on messages generated by automatic or periodic
2790 processes, except for messages which are automatic responses to
2791 other messages.

2827PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2828 canonical form (as documented). However, after a host name lookup from
2829 the IP address, check_host() was doing a simple string comparison with
2830 addresses acquired from the DNS when checking that the found name did
2831 have the original IP as one of its addresses. Since any found IPv6
2832 addresses are likely to be in abbreviated form, the comparison could
2833 fail. Luckily, there already exists a function for doing the comparison
2834 by converting both addresses to binary, so now that is used instead of
2835 the text comparison.

96776534
PH
2837PH/20 There was another similar case to PH/19, when a complete host name was

3135 preserve the sysexits.h value, by assumimg that macro definitions were

PH
3149PH/07 Added "fullpostmaster" verify option, which does a check to <postmaster>
3150 without a domain if the check to <postmaster@domain> fails.

SC
3152SC/01 Eximstats: added -xls and the ability to specify output files
3153 (patch written by Frank Heydlauf).
3154
3155SC/02 Eximstats: use FileHandles for outputing results.
3156
3157SC/03 Eximstats: allow any combination of xls, txt, and html output.
3158
3159SC/04 Eximstats: fixed display of large numbers with -nvr option
3160
3161SC/05 Eximstats: fixed merging of reports with empty tables.
3162
3163SC/06 Eximstats: added the -include_original_destination flag
3164
3165SC/07 Eximstats: removed tabs and trailing whitespace.

3167TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller.
3168
3169TK/06 MBOX spool code: Add real "From " MBOX separator line
3170 so the .eml file is really in mbox format (even though
3171 most programs do not really care). Patch from Alex Miller.
3172
3173TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
3174 The latter is generated from $received_to and is only set if the
3175 message has one envelope recipient. SA can use these headers,
3176 obviously out-of-the-box. Patch from Alex Miller.

PH
3178PH/08 The ${def test on a variable was returning false if the variable's
3179 value was "0", contrary to what the specification has always said!
3180 The result should be true unless the variable is empty.
3181
3182PH/09 The syntax error of a character other than { following "${if
3183 def:variable_name" (after optional whitespace) was not being diagnosed.
3184 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3185 accidental colon was present, for example, could give incorrect results.
3186
0d7eb84a
PH
3187PH/10 Tidied the code in a number of places where the st_size field of a stat()
3188 result is used (not including appendfile, where other changes are about
3189 to be made).
3190
3191PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
3192 This involved changing a lot of size variables from int to off_t. It
3193 should work with maildirs and everything.

3195TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of
3196 spamd dying while we are connected to it.

PH
3201PH/12 Applied Alex Kiernan's patch for the API change for the error callback
3202 function for BDB 4.3.

PH
3204PH/13 Changed auto_thaw such that it does not apply to bounce messages.
3205
8ac170f3
PH
3206PH/14 Imported PCRE 6.0; this was more than just a trivial operation because
3207 the sources for PCRE have been re-arranged and more files are now
3208 involved.
3209

PH
3210PH/15 The code I had for printing potentially long long variables in PH/11
3211 above was not the best (it lost precision). The length of off_t variables
3212 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3213 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3214 to be "long long int" or "long int". This is needed for the internal
3215 formatting function string_vformat().

4aac9b49
PH
3217PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3218 the configuration file to be ":syslog", then the script "guesses" where
3219 the logs files are, rather than using the compiled in default. In our
3220 case the guess is not the same as the compiled default, so the script
3221 suddenly stopped working when I started to use syslog. The patch checks
3222 to see if log_file_path is "". If so, it attempts to read it from exim
3223 with no configuration file to get the compiled in version, before it
3224 falls back to the previous guessing code."
3225
294520c8
TK
3226TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with
3227 implementing BATV in an Exim configuration. See NewStuff for the gory
3228 details.
3229

PH
3230PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and
3231 Makefile that are specific to HP-UX.
3232
90e9ce59
PH
3233PH/18 If the "use_postmaster" option was set for a recipient callout together
3234 with the "random" option, the postmaster address was used as the MAIL
3235 FROM address for the random test, but not for the subsequent recipient
3236 test. It is now used for both.
3237
5ea81592
PH
3238PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3239 patch removes a few documentation additions to RFC 3028, because the
3240 latest draft now contains them. It adds the new en;ascii-case comparator
3241 and a new error check for 8bit text in MIME parts. Comparator and
3242 require names are now matched exactly. I enabled the subaddress
3243 extension, but it is not well tested yet (read: it works for me)."
3244
c6c2dc1d
PH
3245PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3246 rework some of the code of TK/09 above to avoid the hardwired use of
3247 "%lld" and "long long". Replaced the call to snprintf() with a call to
3248 string_vformat().
3249
fffffe4c
PH
3250PH/21 Added some other messages to those in 4.51/PH/42, namely "All relevant MX
3251 records point to non-existent hosts", "retry timeout exceeded", and
3252 "retry time not reached for any host after a long failure period".

9a26b6b2
PH
3254PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3255 experimental DomainKeys support:
3256
3257 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3258 (2) On an error such as an illegally used "control", the wrong name for
3259 the control was given.
3260
3261 These problems did NOT occur unless DomainKeys support was compiled.
3262
4aee0225
PH
3263PH/23 Added daemon_startup_retries and daemon_startup_sleep.
3264
32d668a5
PH
3265PH/24 Added ${if match_ip condition.
3266
8187c3f3
PH
3267PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3268 databases so that it will be absolutely obvious if a crash occurs in the
3269 DB library. This is a regular occurrence (often caused by mis-matched
3270 db.h files).
3271
ff790e47 3272PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3273 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3274 picked up on a user's system that detects such things. There doesn't seem
3275 to be a gcc warning option for this - only an attribute that has to be
3276 put on the function's prototype. It seems that in Fedora Core 4 they have
3277 set this on a number of new functions. No doubt there will be more in due
3278 course.
ff790e47 3279
5417f6d1
PH
3280PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3281 specify a transport. However, if an address that was verified by such a
3282 router was the subject of a callout, Exim crashed because it tried to
3283 read the rcpt_include_affixes from the non-existent transport. Now it
3284 just assumes that the setting of that option is false. This bug was
3285 introduced by 4.51/PH/31.
3286
59cf8544
PH
3287PH/28 Changed -d+all to exclude +memory, because that information is very
3288 rarely of interest, but it makes the output a lot bigger. People tend to
3289 do -d+all out of habit.
3290
e7ad8a65
PH
3291PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the
3292 code in os-type was giving problems when libc.so lives in lib64, like on
3293 x86_64 Fedora Core.
3294
ade42478
PH
3295PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3296 aren't the modern standard, and it seems that some systems' include files
3297 don't always have them. Exim was already checking for some of the newer
3298 ones like T_AAAA, and defining it itself. I've added checks for all the
3299 record types that Exim uses.
3300
182ad5cf
PH
3301PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3302 not automatically generating a new one, as it is supposed to. This
3303 prevented TLS from working. If the file did exist, but contained invalid
3304 data, a new version was generated, as expected. It was only the case of a
3305 non-existent file that was broken.

TK
3307TK/10 Domainkeys: Fix a bug in verification that caused a crash in conjunction
3308 with a change in libdomainkeys > 0.64.
3309
3310TK/11 Domainkeys: Change the logic how the "testing" policy flag is retrieved
3311 from DNS. If the selector record carries the flag, it now has
3312 precedence over the domain-wide flag.
3313
3314TK/12 Cleared some compiler warnings related to SPF, SRS and DK code.
3315
47c7a64a
PH
3316PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3317 the use of a port name that isn't defined in /etc/services) occurred, the
3318 message was deferred as in a normal delivery, and thus remained on the
3319 spool, instead of being failed because of the mua_wrapper setting. This
3320 is now fixed, and I tidied up some of the mua_wrapper messages at the
3321 same time.
3322

SC
3323SC/08 Eximstats: whilst parsing the mainlog(s), store information about
3324 the messages in a hash of arrays rather than using individual hashes.
3325 This is a bit cleaner and results in dramatic memory savings, albeit
3326 at a slight CPU cost.
3327
3328SC/09 Eximstats: added the -show_rt<list> and the -show_dt<list> flags
3329 as requested by Marc Sherman.
3330
3331SC/10 Eximstats: added histograms for user specified patterns as requested
3332 by Marc Sherman.
