7JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
8 and 3.4.4 - once the server is enabled to respond to an OCSP request
9 it does even when not requested, resulting in a stapling non-aware
10 client dropping the TLS connection.

12TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
13 support variable-length bit vectors. No functional change.

TF
15TF/02 Improve the consistency of logging incoming and outgoing interfaces.
16 The I= interface field on outgoing lines is now after the H= remote
17 host field, same as incoming lines. There is a separate
18 outgoing_interface log selector which allows you to disable the
19 outgoing I= field.

JH
21JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
22 If not running log_selector +smtp_connection the mainlog would be held
23 open indefinitely after a "too many connections" event, including to a
24 deleted file after a log rotate. Leave the per net connection logging
25 leaving it open for efficiency as that will be quickly detected by the
26 check on the next write.

28HS/01 Bug 1671: Fix post transport crash.
29 Processing the wait-<transport> messages could crash the delivery
30 process if the message IDs didn't exist for some reason. When
31 using 'split_spool_directory=yes' the construction of the spool
32 file name failed already, exposing the same netto behaviour.

37JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
38 to DSN fail messages (bounces): remote IP, remote greeting, remote response
39 to HELO, local diagnostic string.

805bb5c3
JH
41JH/05 Downgrade message for a TLS-certificate-based authentication fail from
42 log line to debug. Even when configured with a tls authenticator many
43 client connections are expected to not authenticate in this way, so
44 an authenticate fail is not an error.

46HS/02 Add the Exim version string to the process info. This way exiwhat
47 gives some more detail about the running daemon.

49JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
50 matter for fast-change records such as DNSBLs.
51
6f6dedcc
JH
52JH/07 Bug 1678: Always record an interface option value, if set, as part of a
53 retry record, even if constant. There may be multiple transports with
54 different interface settings and the retry behaviour needs to be kept
55 distinct.

63JH/11 Bug 830: use same host for all RCPTS of a message, even under
64 hosts_randomize. This matters a lot when combined with mua_wrapper.

JH
71JH/14 Change header file name for freeradius-client. Relevant if compiling
72 with Radius support; from the Gentoo tree and checked under Fedora.

76JH/16 Bug 1714: Permit an empty string as expansion result for transport
77 option transport_filter, meaning no filtering.

79JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
80
23f3dc67
JH
81JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
82 defaults to "*" (all hosts). The variable is now available when not built
83 with TLS, default unset, mainly to enable keeping the testuite sane.
84 If a server certificate is not supplied (via tls_certificate) an error is
85 logged, and clients will find TLS connections fail on startup. Presumably
86 they will retry in-clear.
87 Packagers of Exim are strongly encouraged to create a server certificate
88 at installation time.
89
240c288f
JH
90HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
91 with the $config_file variable.
92
5ef5dd52
JB
93JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
94 in transport context, after the attempt, and per-recipient. The latter type
95 is per host attempted. The event data is the error message, and the errno
96 information encodes the lookup type (A vs. MX) used for the (first) host,
97 and the trailing two digits of the smtp 4xx reponse.
98

GF
99GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
100 to write to mainlog (or rejectlog, paniclog) in the window between file
101 creation and permissions/ownership being changed. Particularly affects
102 installations where exicyclog is run as root, rather than exim user;
103 result is that the running daemon panics and dies.

107JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
108 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
109 "pri" and "weight". Note that the previous implicit priority given by the
110 list order is no longer honoured.

f444c2c7
JH
143JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
144 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
145 only supported when built with TLS support. The PolarSSL SHA routines
146 are still used when the TLS library is too old for convenient support.
f444c2c7 147
a57b6200
JH
148JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
149 openssl_options), for security. OpenSSL forces this from version 1.1.0
150 server-side so match that on older versions.
151
07c73177 152JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 153 allocation for $value could be released as the expansion processing
07c73177 154 concluded, but leaving the global pointer active for it.

254JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
255 Normally benign, it bites when the pair was led to by a CNAME;
256 modern usage is to not canoicalize the domain to a CNAME target
257 (and we were inconsistent anyway for A-only vs AAAA+A).

280Exim version 4.85
281-----------------
282TL/01 When running the test suite, the README says that variables such as
283 no_msglog_check are global and can be placed anywhere in a specific
284 test's script, however it was observed that placement needed to be near
285 the beginning for it to behave that way. Changed the runtest perl
286 script to read through the entire script once to detect and set these
287 variables, reset to the beginning of the script, and then run through
288 the script parsing/test process like normal.

315JH/05 Fix results-pipe from transport process. Several recipients, combined
316 with certificate use, exposed issues where response data items split
317 over buffer boundaries were not parsed properly. This eventually
318 resulted in duplicates being sent. This issue only became common enough
319 to notice due to the introduction of conection certificate information,
320 the item size being so much larger. Found and fixed by Wolfgang Breyha.

392TF/01 Correctly close the server side of TLS when forking for delivery.
393
394 When a message was received over SMTP with TLS, Exim failed to clear up
395 the incoming connection properly after forking off the child process to
396 deliver the message. In some situations the subsequent outgoing
397 delivery connection happened to have the same fd number as the incoming
398 connection previously had. Exim would try to use TLS and fail, logging
399 a "Bad file descriptor" error.

645TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
646
647 When a queue runner is handling a message, Exim first routes the
648 recipient addresses, during which it prunes them based on the retry
649 hints database. After that it attempts to deliver the message to
650 any remaining recipients. It then updates the hints database using
651 the retry rules.
652
653 So if a recipient address works intermittently, it can get repeatedly
654 deferred at routing time. The retry hints record remains fresh so the
655 address never reaches the final cutoff time.
656
657 This is a fairly common occurrence when a user is bumping up against
658 their storage quota. Exim had some logic in its local delivery code
659 to deal with this. However it did not apply to per-recipient defers
660 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
661
1ddeb334
TF
662 This change adds a proper retry rule check during routing so that the
663 final cutoff time is checked against the message's age. We only do
664 this check if there is an address retry record and there is not a
665 domain retry record; this implies that previous attempts to handle
666 the address had the retry_use_local_parts option turned on. We use
667 this as an approximation for the destination being like a local
668 delivery, as in LMTP.
67bd1ab3
TF
669
670 I suspect this new check makes the old local delivery cutoff check
671 redundant, but I have not verified this so I left the code in place.

710 acl_data_smtp_prdr ACL is called once for each recipient, after
711 the body content is received and before the acl_smtp_data ACL.
712 The client is controlled by bolth of: a hosts_try_prdr option
713 on the smtp transport, and the server advertisement.
714 Default client logging of deliveries and rejections involving

993TF/03 Make the exiwhat support code safe for signals. Previously Exim might
994 lock up or crash if it happened to be inside a call to libc when it
995 got a SIGUSR1 from exiwhat.
996
997 The SIGUSR1 handler appends the current process status to the process
998 log which is later printed by exiwhat. It used to use the general
999 purpose logging code to do this, but several functions it calls are
1000 not safe for signals.
1001
1002 The new output code in the SIGUSR1 handler is specific to the process
1003 log, and simple enough that it's easy to inspect for signal safety.
1004 Removing some special cases also simplifies the general logging code.
1005 Removing the spurious timestamps from the process log simplifies
1006 exiwhat.
1007

TF
1008TF/04 Improved ratelimit ACL condition.
1009
1010 The /noupdate option has been deprecated in favour of /readonly which
1011 has clearer semantics. The /leaky, /strict, and /readonly update modes
1012 are mutually exclusive. The update mode is no longer included in the
1013 database key; it just determines when the database is updated. (This
1014 means that when you upgrde Exim will forget old rate measurements.)
1015
1016 Exim now checks that the per_* options are used with an update mode that
1017 makes sense for the current ACL. For example, when Exim is processing a
1018 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1019 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1020 must specify per_mail/readonly. If you omit the update mode it defaults to
1021 /leaky where that makes sense (as before) or /readonly where required.
1022
1023 The /noupdate option is now undocumented but still supported for
1024 backwards compatibility. It is equivalent to /readonly except that in
1025 ACLs where /readonly is required you may specify /leaky/noupdate or
1026 /strict/noupdate which are treated the same as /readonly.
1027
1028 A useful new feature is the /count= option. This is a generalization
1029 of the per_byte option, so that you can measure the throughput of other
1030 aggregate values. For example, the per_byte option is now equivalent
1031 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1032
1033 The per_rcpt option has been generalized using the /count= mechanism
1034 (though it's more complicated than the per_byte equivalence). When it is
1035 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1036 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1037 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1038 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1039 Note that using per_rcpt with a non-readonly update mode in more than
1040 one ACL will cause the recipients to be double-counted. (The per_mail
1041 and per_byte options don't have this problem.)
1042
1043 The handling of very low rates has changed slightly. If the computed rate
1044 is less than the event's count (usually one) then this event is the first
1045 after a long gap. In this case the rate is set to the same as this event's
1046 count, so that the first message of a spam run is counted properly.
1047
1048 The major new feature is a mechanism for counting the rate of unique
1049 events. The new per_addr option counts the number of different
1050 recipients that someone has sent messages to in the last time period. It
1051 behaves like per_rcpt if all the recipient addresses are different, but
1052 duplicate recipient addresses do not increase the measured rate. Like
1053 the /count= option this is a general mechanism, so the per_addr option
1054 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1055 example, measure the rate that a client uses different sender addresses
1056 with the options per_mail/unique=$sender_address. There are further
1057 details in the main documentation.

1608 were called 'true' and it seems that C99 defines that as a reserved

1629PH/01 Another patch from the Sieve maintainer.
1630
6a3bceb1
PH
1631PH/02 When an IPv6 address is converted to a string for single-key lookup
1632 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1633 dots are used instead of colons so that keys in lsearch files need not
1634 contain colons. This was done some time before quoting was made available
1635 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1636 (notated using the quote facility) so as to distinguish them from IPv4
1637 keys. This meant that lookups for IP addresses in host lists did not work
1638 for iplsearch lookups.
1639
1640 This has been fixed by arranging for IPv6 addresses to be expressed with
1641 colons if the lookup type is iplsearch. This is not incompatible, because
1642 previously such lookups could never work.
1643
1644 The situation is now rather anomolous, since one *can* have colons in
1645 ordinary lsearch keys. However, making the change in all cases is
1646 incompatible and would probably break a number of configurations.

MH
1651MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1652 conversion specification without a maximum field width, thereby enabling
1653 a rogue spamd server to cause a buffer overflow. While nobody in their
1654 right mind would setup Exim to query an untrusted spamd server, an
1655 attacker that gains access to a server running spamd could potentially
1656 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1661MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1662 a directory entry by the name of the lookup key. Previously, if a
1663 symlink pointed to a non-existing file or a file in a directory that
1664 Exim lacked permissions to read, a lookup for a key matching that
1665 symlink would fail. Now it is enough that a matching directory entry
1666 exists, symlink or not. (Bugzilla 503.)

1743 if a client was not listed at all, or was listed with a value other than
1744 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

PH
1849PH/29 SMTP synchronization checks are implemented when a command is read -
1850 there is a check that no more input is waiting when there shouldn't be
1851 any. However, for some commands, a delay in an ACL can mean that it is
1852 some time before the response is written. In this time, more input might
1853 arrive, invalidly. So now there are extra checks after an ACL has run for
1854 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1855 pipelining has not been advertised.

PH
1867PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1868 Exim which did not show up earlier: it was assuming that a call to
1869 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1870 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1871 was a macro that became an assignment, so it seemed to work. This has
1872 changed to a proper function call with a void return, hence the compile
1873 error. Exim's code has been fixed.

1901PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1902 whoever called Exim into the -H file. In the case of the daemon it was
1903 behaving confusingly. When first started, it used values for whoever
1904 started the daemon, but after a SIGHUP it used the Exim user (because it
1905 calls itself on a restart). I have changed the code so that it now always
1906 uses the Exim user.

1911 with PIPELINING or a stupid MUA), the error message that was given to the
1912 RCPT commands is included in the rejection of the DATA command. This is

PH
1929 the response to the final '.' that terminates a message, but only in the
1930 case where the client has not sent further data following the '.'
1931 (unfortunately, this is allowed). However, in many cases there won't be
1932 any further data because there won't be any more messages to send. A call
1933 to select() can be used: if it shows that the input is "ready", there is
1934 either input waiting, or the socket has been closed. An attempt to read
1935 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1936 would have sent an OK response which the client would never have see.

1948 fixed by 4.65/MH/01 (is this a record?) are fixed:
1949
1950 (i) An empty string was always treated as zero by the numeric comparison
1951 operators. This behaviour has been restored.
1952
1953 (ii) It is documented that the numeric comparison operators always treat
1954 their arguments as decimal numbers. This was broken in that numbers
1955 starting with 0 were being interpreted as octal.
1956
1957 While fixing these problems I realized that there was another issue that
1958 hadn't been noticed. Values of message_size_limit (both the global option
1959 and the transport option) were treated as octal if they started with 0.
1960 The documentation was vague. These values are now always treated as
1961 decimal, and I will make that clear in the documentation.

PH
1975PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1976 child addresses, Exim now panics and dies. Previously, because the count
1977 is held in a short int, deliveries were likely to be lost. As such a
1978 large number of recipients for a single message is ridiculous
1979 (performance will be very, very poor), I have chosen to impose a limit
1980 rather than extend the field.

1986TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1987 leftover -K file (the existence of which was triggered by #402).
1988 While we were at it, introduced process PID as part of the -K
1989 filename. This should rule out race conditions when creating
1990 these files.
1991
1992TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1993 processing considerably. Previous code took too long for large mails,
1994 triggering a timeout which in turn triggers #401.
1995
1996TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1997 in the DK code in transports.c. sendfile() is not really portable,
1998 hence the _LINUX specificness.

2000TF/01 In the add_headers option to the mail command in an Exim filter,
2001 there was a bug that Exim would claim a syntax error in any
2002 header after the first one which had an odd number of characters
2003 in the field name.

2b1c6e3a
PH
2005PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2006 callout verification, Exim cached a "reject" for the entire domain. This
2007 is correct for most verifications, but it is not correct for a recipient
2008 verification with use_sender or use_postmaster set, because in that case
2009 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2010 case of MAIL FROM:<> rejection from other early rejections (e.g.
2011 rejection of HELO). When verifying a recipient using a non-null MAIL
2012 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2013 Whatever the result of the callout, the value of the domain cache is
2014 left unchanged (for any other kind of callout, getting as far as trying
2015 RCPT means that the domain itself is ok).

2049PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2050 hostname. This is wrong, because it relates to the incoming message (and
2051 probably the interface on which it is arriving) and not to the outgoing
2052 callout (which could be using a different interface). This has been
2053 changed to use the value of the helo_data option from the smtp transport
2054 instead - this is what is used when a message is actually being sent. If
2055 there is no remote transport (possible with a router that sets up host
2056 addresses), $smtp_active_hostname is used.

14aa5a05 2058PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2059 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2060 (a) The code assumed that strncpy() returns a negative number on buffer
2061 overflow, which isn't the case. Replaced with Exim's string_format()
2062 function.
2063 (b) There were several signed/unsigned issues. I just did the minimum
2064 hacking in of casts. There is scope for a larger refactoring.
2065 (c) The code used strcasecmp() which is not a standard C function.
2066 Replaced with Exim's strcmpic() function.
2067 (d) The code set only $1; it now sets $auth1 as well.
2068 (e) A simple test gave the error "authentication client didn't specify
2069 service in request". It would seem that Dovecot has changed its
2070 interface. Fortunately there's a specification; I followed it and
2071 changed what the client sends and it appears to be working now.

PH
2076PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2077 address A is aliased to B and C, where B exists and C does not. Without
2078 -v the output is "A verified" because verification stops after a
2079 successful redirection if more than one address is generated. However,
2080 with -v the child addresses are also verified. Exim was outputting "A
2081 failed to verify" and then showing the successful verification for C,
2082 with its parentage. It now outputs "B failed to verify", showing B's
2083 parentage before showing the successful verification of C.

2085PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2086 look up a TXT record in a specific list after matching in a combined
2087 list.
2088
322050c2
PH
2089PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2090 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2091 they consult the DNS. I had assumed they would set it the way they
2092 wanted; and indeed my experiments on Linux seem to show that in some
2093 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2094 To be on the safe side, however, I have now made the interface to
2095 host_find_byname() similar to host_find_bydns(), with an argument
2096 containing the DNS resolver options. The host_find_byname() function now
2097 sets these options at its start, just as host_find_bydns() does. The smtp
2098 transport options dns_qualify_single and dns_search_parents are passed to
2099 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2100 of host_find_byname() use the default settings of RES_DEFNAMES
2101 (qualify_single) but not RES_DNSRCH (search_parents).
2102

PH
2103PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2104 spool_read_header() do less string testing, by means of a preliminary
2105 switch on the second character of optional "-foo" lines. (This is
2106 overdue, caused by the large number of possibilities that now exist.
2107 Originally there were few.) While I was there, I also converted the
2108 str(n)cmp tests so they don't re-test the leading "-" and the first
2109 character, in the hope this might squeeze out yet more improvement.
2110

PH
2111PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2112 flag allowing group syntax was set by the header_syntax check but not
2113 turned off, possible causing trouble later; (2) The flag was not being
2114 set at all for the header_verify test, causing "group"-style headers to
2115 be rejected. I have now set it in this case, and also caused header_
2116 verify to ignore an empty address taken from a group. While doing this, I
2117 came across some other cases where the code for allowing group syntax
2118 while scanning a header line wasn't quite right (mostly, not resetting
2119 the flag correctly in the right place). These bugs could have caused
2120 trouble for malformed header lines. I hope it is now all correct.
2121
602e59e5
PH
2122PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2123 with the "reply" argument non-NULL. The code, however (which originally
2124 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2125 but it didn't always do it. This confused somebody who was copying the
2126 code for some other use. I have removed all the tests.
2127
411ef850
PH
2128PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2129 feature that was used to support insecure browsers during the U.S. crypto
2130 embargo. It requires special client support, and Exim is probably the
2131 only MTA that supported it -- and would never use it because real RSA is
2132 always available. This code has been removed, because it had the bad
2133 effect of slowing Exim down by computing (never used) parameters for the
2134 RSA_EXPORT functionality.
2135
7befa435
PH
2136PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2137 authenticator to fail if there's a tab character in the incoming data
2138 (there should never be unless someone is messing about, as it's supposed
2139 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2140 if the connection is using TLS or if the remote IP is the same as the
2141 local IP, and the "valid-client-cert option" if a client certificate has
2142 been verified.
2143
48da4259 2144PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
2173
2174PH/30 Exim was sometimes attempting to deliver messages that had suffered
2175 address errors (4xx response to RCPT) over the same connection as other
2176 messages routed to the same hosts. Such deliveries are always "forced",
2177 so retry times are not inspected. This resulted in far too many retries
2178 for the affected addresses. The effect occurred only when there were more
2179 hosts than the hosts_max_try setting in the smtp transport when it had
2180 the 4xx errors. Those hosts that it had tried were not added to the list
2181 of hosts for which the message was waiting, so if all were tried, there
2182 was no problem. Two fixes have been applied:
2183
2184 (i) If there are any address or message errors in an SMTP delivery, none
2185 of the hosts (tried or untried) are now added to the list of hosts
2186 for which the message is waiting, so the message should not be a
2187 candidate for sending over the same connection that was used for a
2188 successful delivery of some other message. This seems entirely
2189 reasonable: after all the message is NOT "waiting for some host".
2190 This is so "obvious" that I'm not sure why it wasn't done
2191 previously. Hope I haven't missed anything, but it can't do any
2192 harm, as the worst effect is to miss an optimization.
2193
2194 (ii) If, despite (i), such a delivery is accidentally attempted, the
2195 routing retry time is respected, so at least it doesn't keep
2196 hammering the server.

2207PH/34 The spec says: "With one important exception, whenever a domain list is

520de300
PH
2211PH/35 The error "getsockname() failed: connection reset by peer" was being
2212 written to the panic log as well as the main log, but it isn't really
2213 panic-worthy as it just means the connection died rather early on. I have
2214 removed the panic log writing for the ECONNRESET error when getsockname()
2215 fails.
2216
48c7f9e2
PH
2217PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2218 runs only) independently of the message's sender address. This meant
2219 that, if the 4xx error was in fact related to the sender, a different
2220 message to the same recipient with a different sender could confuse
2221 things. In particualar, this can happen when sending to a greylisting
2222 server, but other circumstances could also provoke similar problems.
2223 I have changed the default so that the retry time for these errors is now
2224 based a combination of the sender and recipient addresses. This change
2225 can be overridden by setting address_retry_include_sender=false in the
2226 smtp transport.

2228PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

2494PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2496 Unfortunately, if there is a major crisis, such as a disk failure,
2497 tcp-wrappers gives "deny", whereas what one would like would be some
2498 kind of temporary error. A kludge has been added to help with this.
2499 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2500 554 error is used if errno is still zero or contains ENOENT (which occurs
2501 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2502 451 error is used.

2538PH/01 The code for finding all the local interface addresses on a FreeBSD
2539 system running IPv6 was broken. This may well have applied to all BSD
2540 systems, as well as to others that have similar system calls. The broken
2541 code found IPv4 interfaces correctly, but gave incorrect values for the
2542 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2543 that it would not match correctly against @[] and not recognize the IPv6
2544 addresses as local.

2585 syntactically invalid From: or Reply-to: line, and a filter used this to
2586 generate an autoreply, and therefore failed to obtain an address for the
2587 autoreply, Exim could try to deliver to a non-existent relative file
2588 name, causing unrelated and misleading errors. What now happens is that
2589 it logs this as a hard delivery error, but does not attempt to create a

2607 non-existent - all you got was a failure to exec. I have made two
2608 changes:
2609
2610 (a) Failures to set uid/gid, the current directory, or a process leader
2611 in a subprocess such as that created by queryprogram now generate
2612 suitable debugging ouput when -d is set.
2613
2614 (b) The queryprogram router detects when it is not running as root,
2615 outputs suitable debugging information if -d is set, and then runs
2616 the subprocess without attempting to change uid/gid.

2621PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2622 additional section of a DNS packet that returns MX or SRV records.
2623 Instead, it always explicitly searches for A/AAAA records. This avoids
2624 major problems that occur when a DNS server includes only records of one
2625 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2626 fixed another bug: if SRV records were looked up and the corresponding
2627 address records were *not* found in the additional section, the port
2628 values from the SRV records were lost.

2630PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2637
727071f8
PH
2638PH/19 When calculating a retry time, Exim used to measure the "time since
2639 failure" by looking at the "first failed" field in the retry record. Now
2640 it does not use this if it is later than than the arrival time of the
2641 message. Instead it uses the arrival time. This makes for better
2642 behaviour in cases where some deliveries succeed, thus re-setting the
2643 "first failed" field. An example is a quota failure for a huge message
2644 when small messages continue to be delivered. Without this change, the
2645 "time since failure" will always be short, possible causing more frequent
2646 delivery attempts for the huge message than are intended.

PH
2743PH/42 The content-scanning code uses fopen() to create files in which to put
2744 message data. Previously it was not paying any attention to the mode of
2745 the files. Exim runs with umask(0) because the rest of the code creates
2746 files with open(), and sets the required mode explicitly. Thus, these
2747 files were ending up world-writeable. This was not a big issue, because,
2748 being within the spool directory, they were not world-accessible. I have
2749 created a function called modefopen, which takes an additional mode
2750 argument. It sets umask(777), creates the file, chmods it to the required
2751 mode, then resets the umask. All the relevant calls to fopen() in the
2752 content scanning code have been changed to use this function.

2760PH/45 When the plaintext authenticator is running as a client, the server's
2761 challenges are checked to ensure they are valid base64 strings. By
2762 default, the authentication attempt is cancelled if an invalid string is
2763 received. Setting client_ignore_invalid_base64 true ignores these errors.
2764 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2765 they are received. Thus, the responses can be made to depend on the
2766 challenges. If an invalid string is ignored, an empty string is placed in

2787PH/52 Two bugs concerned with error handling when the smtp transport is
2788 used in LMTP mode:
2789
2790 (i) Exim was not creating retry information for temporary errors given
2791 for individual recipients after the DATA command when the smtp transport
2792 was used in LMTP mode. This meant that they could be retried too
2793 frequently, and not timed out correctly.
2794
2795 (ii) Exim was setting the flag that allows error details to be returned
2796 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2797 recipients that were returned after the DATA command.
2798
2799PH/53 This is related to PH/52, but is more general: for any failing address,
2800 when detailed error information was permitted to be returned to the
2801 sender, but the error was temporary, then after the final timeout, only
2802 "retry timeout exceeded" was returned. Now it returns the full error as
2803 well as "retry timeout exceeded".

2873PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2874 function verify_get_ident() calls ip_connect() to connect a socket, but
2875 if the "connect()" function timed out, ip_connect() used to close the
2876 socket. However, verify_get_ident() also closes the socket later, and in
2877 between Exim writes to the log, which may get opened at this point. When
2878 the socket was closed in ip_connect(), the log could get the same file
2879 descriptor number as the socket. This naturally causes chaos. The fix is
2880 not to close the socket in ip_connect(); the socket should be closed by
2881 the function that creates it. There was only one place in the code where
2882 this was missing, in the iplookup router, which I don't think anybody now
2883 uses, but I've fixed it anyway.

2906
2907 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2908 string.
2909
2910 (3) Reset the variables that are obtained from the first argument of
2911 ${prvscheck and used in the second argument before leaving the code,
2912 because their memory is reclaimed, so using them afterwards may do
2913 silly things.
2914
2915 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2916 one (it's much easier than Tom thought :-).

2939PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2940 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2941 not being looked up in the rDNS to get a host name, Exim was showing the
2942 IP address twice in Received: lines, even though the IP addresses were
2943 identical. For example:
2944
2945 Received: from [1.2.3.4] (helo=[1.2.3.4])
2946
2947 However, if the real host name was known, it was omitting the HELO data
2948 if it matched the actual IP address. This has been tidied up so that it
2949 doesn't show the same IP address twice.

2975PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2977
2978 Auto-submitted: auto-generated
2979
2980 in the messages that it generates (bounce messages and others, such as
2981 warnings). In the case of bounce messages for non-SMTP mesages, there was
2982 also a typo: it was using "Auto_submitted" (underscore instead of
2983 hyphen). Since every message generated by Exim is necessarily in response
2984 to another message, thes have all been changed to:
2985
2986 Auto-Submitted: auto-replied
2987
2988 in accordance with these statements in the RFC:
2989
2990 The auto-replied keyword:
2991
2992 - SHOULD be used on messages sent in direct response to another

3041 addresses acquired from the DNS when checking that the found name did
3042 have the original IP as one of its addresses. Since any found IPv6
3043 addresses are likely to be in abbreviated form, the comparison could
3044 fail. Luckily, there already exists a function for doing the comparison
3045 by converting both addresses to binary, so now that is used instead of
3046 the text comparison.

3163PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3164 authentication with radiusclient 0.4.9:
3165
3166 - Error returned from rc_read_config was caught wrongly
3167 - Username/password not passed on to radius server due to wrong length.
3168
3169 The presumption is that some radiusclient API changes for 4.51/PH/17
3170 were not taken care of correctly. The code is still untested by me (my
3171 Linux distribution still has 0.3.2 of radiusclient), but it was
3172 contributed by a Radius user.

3187PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3224PH/36 When a locally submitted message by a trusted user did not contain a
3225 From: header, and the sender address was obtained from -f or from an SMTP
3226 MAIL command, and the trusted user did not use -F to supply a sender
3227 name, $originator_name was incorrectly used when constructing a From:
3228 header. Furthermore, $originator_name was used for submission mode
3229 messages from external hosts without From: headers in a similar way,
3230 which is clearly wrong.
