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.

TF
12TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
13 support variable-length bit vectors. No functional change.
14

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.

34JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
35 mime_regex ACL conditions.

JH
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.
40
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.

JH
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.
65
98b98887 66JH/12 Bug 1706: percent and underbar characters are no longer escaped by the

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.

75
6ff55e50
JH
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
e161710d
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.

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.

138 it.
139
01a4a5c5 140JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 141 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
142 can be used to disable this per-host. The build option
143 EXPERIMENTAL_CERTNAMES is withdrawn.

JH
147 For GnuTLS, only version 3.0.20 or later.
148
610ff438 149JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19

150 (but not required) by default. The verification status is now logged by
151 default, for both outbound TLS and client-certificate supplying inbound
152 TLS connections

50dc7409
JH
157JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
158 Status Notification (bounce) messages are now MIME format per RFC 3464.
159 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
160 under the control of the dsn_advertise_hosts option, and routers may
161 have a dsn_lasthop option.

224JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
225 Normally benign, it bites when the pair was led to by a CNAME;
226 modern usage is to not canoicalize the domain to a CNAME target
227 (and we were inconsistent anyway for A-only vs AAAA+A).

250Exim version 4.85
251-----------------
252TL/01 When running the test suite, the README says that variables such as
253 no_msglog_check are global and can be placed anywhere in a specific
254 test's script, however it was observed that placement needed to be near
255 the beginning for it to behave that way. Changed the runtest perl
256 script to read through the entire script once to detect and set these
257 variables, reset to the beginning of the script, and then run through
258 the script parsing/test process like normal.

WB
285JH/05 Fix results-pipe from transport process. Several recipients, combined
286 with certificate use, exposed issues where response data items split
287 over buffer boundaries were not parsed properly. This eventually
288 resulted in duplicates being sent. This issue only became common enough
289 to notice due to the introduction of conection certificate information,
290 the item size being so much larger. Found and fixed by Wolfgang Breyha.

aec45841 302 and $event_defer_errno. There is a new variable $verify_mode, usable in

362TF/01 Correctly close the server side of TLS when forking for delivery.
363
364 When a message was received over SMTP with TLS, Exim failed to clear up
365 the incoming connection properly after forking off the child process to
366 deliver the message. In some situations the subsequent outgoing
367 delivery connection happened to have the same fd number as the incoming
368 connection previously had. Exim would try to use TLS and fail, logging
369 a "Bad file descriptor" error.

615TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
616
617 When a queue runner is handling a message, Exim first routes the
618 recipient addresses, during which it prunes them based on the retry
619 hints database. After that it attempts to deliver the message to
620 any remaining recipients. It then updates the hints database using
621 the retry rules.
622
623 So if a recipient address works intermittently, it can get repeatedly
624 deferred at routing time. The retry hints record remains fresh so the
625 address never reaches the final cutoff time.
626
627 This is a fairly common occurrence when a user is bumping up against
628 their storage quota. Exim had some logic in its local delivery code
629 to deal with this. However it did not apply to per-recipient defers
630 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
631
1ddeb334
TF
632 This change adds a proper retry rule check during routing so that the
633 final cutoff time is checked against the message's age. We only do
634 this check if there is an address retry record and there is not a
635 domain retry record; this implies that previous attempts to handle
636 the address had the retry_use_local_parts option turned on. We use
637 this as an approximation for the destination being like a local
638 delivery, as in LMTP.
67bd1ab3
TF
639
640 I suspect this new check makes the old local delivery cutoff check
641 redundant, but I have not verified this so I left the code in place.

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

676 Server implementation by Todd Lyons, client by JH.

679 advertises the facility. If the client requests PRDR a new
680 acl_data_smtp_prdr ACL is called once for each recipient, after
681 the body content is received and before the acl_smtp_data ACL.
682 The client is controlled by bolth of: a hosts_try_prdr option
683 on the smtp transport, and the server advertisement.
684 Default client logging of deliveries and rejections involving
685 PRDR are flagged with the string "PRDR".

963TF/03 Make the exiwhat support code safe for signals. Previously Exim might
964 lock up or crash if it happened to be inside a call to libc when it
965 got a SIGUSR1 from exiwhat.
966
967 The SIGUSR1 handler appends the current process status to the process
968 log which is later printed by exiwhat. It used to use the general
969 purpose logging code to do this, but several functions it calls are
970 not safe for signals.
971
972 The new output code in the SIGUSR1 handler is specific to the process
973 log, and simple enough that it's easy to inspect for signal safety.
974 Removing some special cases also simplifies the general logging code.
975 Removing the spurious timestamps from the process log simplifies
976 exiwhat.
977
c99ce5c9
TF
978TF/04 Improved ratelimit ACL condition.
979
980 The /noupdate option has been deprecated in favour of /readonly which
981 has clearer semantics. The /leaky, /strict, and /readonly update modes
982 are mutually exclusive. The update mode is no longer included in the
983 database key; it just determines when the database is updated. (This
984 means that when you upgrde Exim will forget old rate measurements.)
985
986 Exim now checks that the per_* options are used with an update mode that
987 makes sense for the current ACL. For example, when Exim is processing a
988 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
989 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
990 must specify per_mail/readonly. If you omit the update mode it defaults to
991 /leaky where that makes sense (as before) or /readonly where required.
992
993 The /noupdate option is now undocumented but still supported for
994 backwards compatibility. It is equivalent to /readonly except that in
995 ACLs where /readonly is required you may specify /leaky/noupdate or
996 /strict/noupdate which are treated the same as /readonly.
997
998 A useful new feature is the /count= option. This is a generalization
999 of the per_byte option, so that you can measure the throughput of other
1000 aggregate values. For example, the per_byte option is now equivalent
1001 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1002
1003 The per_rcpt option has been generalized using the /count= mechanism
1004 (though it's more complicated than the per_byte equivalence). When it is
1005 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1006 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1007 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1008 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1009 Note that using per_rcpt with a non-readonly update mode in more than
1010 one ACL will cause the recipients to be double-counted. (The per_mail
1011 and per_byte options don't have this problem.)
1012
1013 The handling of very low rates has changed slightly. If the computed rate
1014 is less than the event's count (usually one) then this event is the first
1015 after a long gap. In this case the rate is set to the same as this event's
1016 count, so that the first message of a spam run is counted properly.
1017
1018 The major new feature is a mechanism for counting the rate of unique
1019 events. The new per_addr option counts the number of different
1020 recipients that someone has sent messages to in the last time period. It
1021 behaves like per_rcpt if all the recipient addresses are different, but
1022 duplicate recipient addresses do not increase the measured rate. Like
1023 the /count= option this is a general mechanism, so the per_addr option
1024 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1025 example, measure the rate that a client uses different sender addresses
1026 with the options per_mail/unique=$sender_address. There are further
1027 details in the main documentation.

1577 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1578 were called 'true' and it seems that C99 defines that as a reserved

1580 not include C99-style headers which use bools without triggering

1599PH/01 Another patch from the Sieve maintainer.
1600
6a3bceb1
PH
1601PH/02 When an IPv6 address is converted to a string for single-key lookup
1602 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1603 dots are used instead of colons so that keys in lsearch files need not
1604 contain colons. This was done some time before quoting was made available
1605 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1606 (notated using the quote facility) so as to distinguish them from IPv4
1607 keys. This meant that lookups for IP addresses in host lists did not work
1608 for iplsearch lookups.
1609
1610 This has been fixed by arranging for IPv6 addresses to be expressed with
1611 colons if the lookup type is iplsearch. This is not incompatible, because
1612 previously such lookups could never work.
1613
1614 The situation is now rather anomolous, since one *can* have colons in
1615 ordinary lsearch keys. However, making the change in all cases is
1616 incompatible and would probably break a number of configurations.

MH
1621MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1622 conversion specification without a maximum field width, thereby enabling
1623 a rogue spamd server to cause a buffer overflow. While nobody in their
1624 right mind would setup Exim to query an untrusted spamd server, an
1625 attacker that gains access to a server running spamd could potentially
1626 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1631MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1632 a directory entry by the name of the lookup key. Previously, if a
1633 symlink pointed to a non-existing file or a file in a directory that
1634 Exim lacked permissions to read, a lookup for a key matching that
1635 symlink would fail. Now it is enough that a matching directory entry
1636 exists, symlink or not. (Bugzilla 503.)

1819PH/29 SMTP synchronization checks are implemented when a command is read -
1820 there is a check that no more input is waiting when there shouldn't be
1821 any. However, for some commands, a delay in an ACL can mean that it is
1822 some time before the response is written. In this time, more input might
1823 arrive, invalidly. So now there are extra checks after an ACL has run for
1824 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1825 pipelining has not been advertised.

1840 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1841 was a macro that became an assignment, so it seemed to work. This has
1842 changed to a proper function call with a void return, hence the compile
1843 error. Exim's code has been fixed.

1881 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1899 the response to the final '.' that terminates a message, but only in the
1900 case where the client has not sent further data following the '.'
1901 (unfortunately, this is allowed). However, in many cases there won't be
1902 any further data because there won't be any more messages to send. A call
1903 to select() can be used: if it shows that the input is "ready", there is
1904 either input waiting, or the socket has been closed. An attempt to read
1905 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1906 would have sent an OK response which the client would never have see.

1917PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1918 fixed by 4.65/MH/01 (is this a record?) are fixed:
1919
1920 (i) An empty string was always treated as zero by the numeric comparison
1921 operators. This behaviour has been restored.
1922
1923 (ii) It is documented that the numeric comparison operators always treat
1924 their arguments as decimal numbers. This was broken in that numbers
1925 starting with 0 were being interpreted as octal.
1926
1927 While fixing these problems I realized that there was another issue that
1928 hadn't been noticed. Values of message_size_limit (both the global option
1929 and the transport option) were treated as octal if they started with 0.
1930 The documentation was vague. These values are now always treated as
1931 decimal, and I will make that clear in the documentation.

1956TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1957 leftover -K file (the existence of which was triggered by #402).
1958 While we were at it, introduced process PID as part of the -K
1959 filename. This should rule out race conditions when creating
1960 these files.
1961
1962TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1963 processing considerably. Previous code took too long for large mails,
1964 triggering a timeout which in turn triggers #401.
1965
1966TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1967 in the DK code in transports.c. sendfile() is not really portable,
1968 hence the _LINUX specificness.

1970TF/01 In the add_headers option to the mail command in an Exim filter,
1971 there was a bug that Exim would claim a syntax error in any
1972 header after the first one which had an odd number of characters
1973 in the field name.

PH
1975PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1976 callout verification, Exim cached a "reject" for the entire domain. This
1977 is correct for most verifications, but it is not correct for a recipient
1978 verification with use_sender or use_postmaster set, because in that case
1979 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1980 case of MAIL FROM:<> rejection from other early rejections (e.g.
1981 rejection of HELO). When verifying a recipient using a non-null MAIL
1982 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1983 Whatever the result of the callout, the value of the domain cache is
1984 left unchanged (for any other kind of callout, getting as far as trying
1985 RCPT means that the domain itself is ok).

1990PH/03 On Solaris, an unexpectedly close socket (dropped connection) can
1991 manifest itself as EPIPE rather than ECONNECT. When tidying away a
1992 session, the daemon ignores ECONNECT errors and logs others; it now
1993 ignores EPIPE as well.

PH
2019PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2020 hostname. This is wrong, because it relates to the incoming message (and
2021 probably the interface on which it is arriving) and not to the outgoing
2022 callout (which could be using a different interface). This has been
2023 changed to use the value of the helo_data option from the smtp transport
2024 instead - this is what is used when a message is actually being sent. If
2025 there is no remote transport (possible with a router that sets up host
2026 addresses), $smtp_active_hostname is used.
6ea85e9a 2027
14aa5a05 2028PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2029 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2030 (a) The code assumed that strncpy() returns a negative number on buffer
2031 overflow, which isn't the case. Replaced with Exim's string_format()
2032 function.
2033 (b) There were several signed/unsigned issues. I just did the minimum
2034 hacking in of casts. There is scope for a larger refactoring.
2035 (c) The code used strcasecmp() which is not a standard C function.
2036 Replaced with Exim's strcmpic() function.
2037 (d) The code set only $1; it now sets $auth1 as well.
2038 (e) A simple test gave the error "authentication client didn't specify
2039 service in request". It would seem that Dovecot has changed its
2040 interface. Fortunately there's a specification; I followed it and
2041 changed what the client sends and it appears to be working now.

PH
2046PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2047 address A is aliased to B and C, where B exists and C does not. Without
2048 -v the output is "A verified" because verification stops after a
2049 successful redirection if more than one address is generated. However,
2050 with -v the child addresses are also verified. Exim was outputting "A
2051 failed to verify" and then showing the successful verification for C,
2052 with its parentage. It now outputs "B failed to verify", showing B's
2053 parentage before showing the successful verification of C.

PH
2055PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2056 look up a TXT record in a specific list after matching in a combined
2057 list.
2058
322050c2
PH
2059PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2060 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2061 they consult the DNS. I had assumed they would set it the way they
2062 wanted; and indeed my experiments on Linux seem to show that in some
2063 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2064 To be on the safe side, however, I have now made the interface to
2065 host_find_byname() similar to host_find_bydns(), with an argument
2066 containing the DNS resolver options. The host_find_byname() function now
2067 sets these options at its start, just as host_find_bydns() does. The smtp
2068 transport options dns_qualify_single and dns_search_parents are passed to
2069 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2070 of host_find_byname() use the default settings of RES_DEFNAMES
2071 (qualify_single) but not RES_DNSRCH (search_parents).
2072
08955dd3
PH
2073PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2074 spool_read_header() do less string testing, by means of a preliminary
2075 switch on the second character of optional "-foo" lines. (This is
2076 overdue, caused by the large number of possibilities that now exist.
2077 Originally there were few.) While I was there, I also converted the
2078 str(n)cmp tests so they don't re-test the leading "-" and the first
2079 character, in the hope this might squeeze out yet more improvement.
2080

PH
2081PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2082 flag allowing group syntax was set by the header_syntax check but not
2083 turned off, possible causing trouble later; (2) The flag was not being
2084 set at all for the header_verify test, causing "group"-style headers to
2085 be rejected. I have now set it in this case, and also caused header_
2086 verify to ignore an empty address taken from a group. While doing this, I
2087 came across some other cases where the code for allowing group syntax
2088 while scanning a header line wasn't quite right (mostly, not resetting
2089 the flag correctly in the right place). These bugs could have caused
2090 trouble for malformed header lines. I hope it is now all correct.
2091
602e59e5
PH
2092PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2093 with the "reply" argument non-NULL. The code, however (which originally
2094 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2095 but it didn't always do it. This confused somebody who was copying the
2096 code for some other use. I have removed all the tests.
2097
411ef850
PH
2098PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2099 feature that was used to support insecure browsers during the U.S. crypto
2100 embargo. It requires special client support, and Exim is probably the
2101 only MTA that supported it -- and would never use it because real RSA is
2102 always available. This code has been removed, because it had the bad
2103 effect of slowing Exim down by computing (never used) parameters for the
2104 RSA_EXPORT functionality.
2105
7befa435
PH
2106PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2107 authenticator to fail if there's a tab character in the incoming data
2108 (there should never be unless someone is messing about, as it's supposed
2109 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2110 if the connection is using TLS or if the remote IP is the same as the
2111 local IP, and the "valid-client-cert option" if a client certificate has
2112 been verified.
2113
48da4259 2114PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

2115 authenticators. This can be used for authorization after authentication
2116 succeeds. (In the case of plaintext, it servers for both authentication
2117 and authorization.)

2130PH/27 In a string expansion for a processed (not raw) header when multiple

PH
2143
2144PH/30 Exim was sometimes attempting to deliver messages that had suffered
2145 address errors (4xx response to RCPT) over the same connection as other
2146 messages routed to the same hosts. Such deliveries are always "forced",
2147 so retry times are not inspected. This resulted in far too many retries
2148 for the affected addresses. The effect occurred only when there were more
2149 hosts than the hosts_max_try setting in the smtp transport when it had
2150 the 4xx errors. Those hosts that it had tried were not added to the list
2151 of hosts for which the message was waiting, so if all were tried, there
2152 was no problem. Two fixes have been applied:
2153
2154 (i) If there are any address or message errors in an SMTP delivery, none
2155 of the hosts (tried or untried) are now added to the list of hosts
2156 for which the message is waiting, so the message should not be a
2157 candidate for sending over the same connection that was used for a
2158 successful delivery of some other message. This seems entirely
2159 reasonable: after all the message is NOT "waiting for some host".
2160 This is so "obvious" that I'm not sure why it wasn't done
2161 previously. Hope I haven't missed anything, but it can't do any
2162 harm, as the worst effect is to miss an optimization.
2163
2164 (ii) If, despite (i), such a delivery is accidentally attempted, the
2165 routing retry time is respected, so at least it doesn't keep
2166 hammering the server.

2177PH/34 The spec says: "With one important exception, whenever a domain list is

520de300
PH
2181PH/35 The error "getsockname() failed: connection reset by peer" was being
2182 written to the panic log as well as the main log, but it isn't really
2183 panic-worthy as it just means the connection died rather early on. I have
2184 removed the panic log writing for the ECONNRESET error when getsockname()
2185 fails.
2186
48c7f9e2
PH
2187PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2188 runs only) independently of the message's sender address. This meant
2189 that, if the 4xx error was in fact related to the sender, a different
2190 message to the same recipient with a different sender could confuse
2191 things. In particualar, this can happen when sending to a greylisting
2192 server, but other circumstances could also provoke similar problems.
2193 I have changed the default so that the retry time for these errors is now
2194 based a combination of the sender and recipient addresses. This change
2195 can be overridden by setting address_retry_include_sender=false in the
2196 smtp transport.
2197

PH
2198PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

2201 same for both kinds of LMTP.

2464PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2466 Unfortunately, if there is a major crisis, such as a disk failure,
2467 tcp-wrappers gives "deny", whereas what one would like would be some
2468 kind of temporary error. A kludge has been added to help with this.
2469 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2470 554 error is used if errno is still zero or contains ENOENT (which occurs
2471 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2472 451 error is used.

2508PH/01 The code for finding all the local interface addresses on a FreeBSD

2510 systems, as well as to others that have similar system calls. The broken
2511 code found IPv4 interfaces correctly, but gave incorrect values for the
2512 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2513 that it would not match correctly against @[] and not recognize the IPv6
2514 addresses as local.

2557 autoreply, Exim could try to deliver to a non-existent relative file

2580 (a) Failures to set uid/gid, the current directory, or a process leader
2581 in a subprocess such as that created by queryprogram now generate
2582 suitable debugging ouput when -d is set.
2583

2586 the subprocess without attempting to change uid/gid.

2593 Instead, it always explicitly searches for A/AAAA records. This avoids
2594 major problems that occur when a DNS server includes only records of one
2595 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2596 fixed another bug: if SRV records were looked up and the corresponding
2597 address records were *not* found in the additional section, the port
2598 values from the SRV records were lost.

2600PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2608PH/19 When calculating a retry time, Exim used to measure the "time since
2609 failure" by looking at the "first failed" field in the retry record. Now
2610 it does not use this if it is later than than the arrival time of the
2611 message. Instead it uses the arrival time. This makes for better
2612 behaviour in cases where some deliveries succeed, thus re-setting the
2613 "first failed" field. An example is a quota failure for a huge message
2614 when small messages continue to be delivered. Without this change, the
2615 "time since failure" will always be short, possible causing more frequent
2616 delivery attempts for the huge message than are intended.

2713PH/42 The content-scanning code uses fopen() to create files in which to put

2716 files with open(), and sets the required mode explicitly. Thus, these
2717 files were ending up world-writeable. This was not a big issue, because,
2718 being within the spool directory, they were not world-accessible. I have
2719 created a function called modefopen, which takes an additional mode
2720 argument. It sets umask(777), creates the file, chmods it to the required
2721 mode, then resets the umask. All the relevant calls to fopen() in the
2722 content scanning code have been changed to use this function.

2730PH/45 When the plaintext authenticator is running as a client, the server's
2731 challenges are checked to ensure they are valid base64 strings. By
2732 default, the authentication attempt is cancelled if an invalid string is
2733 received. Setting client_ignore_invalid_base64 true ignores these errors.
2734 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2735 they are received. Thus, the responses can be made to depend on the
2736 challenges. If an invalid string is ignored, an empty string is placed in
2737 the variable.

2757PH/52 Two bugs concerned with error handling when the smtp transport is
2758 used in LMTP mode:
2759
2760 (i) Exim was not creating retry information for temporary errors given
2761 for individual recipients after the DATA command when the smtp transport
2762 was used in LMTP mode. This meant that they could be retried too
2763 frequently, and not timed out correctly.
2764
2765 (ii) Exim was setting the flag that allows error details to be returned
2766 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2767 recipients that were returned after the DATA command.
2768
2769PH/53 This is related to PH/52, but is more general: for any failing address,
2770 when detailed error information was permitted to be returned to the
2771 sender, but the error was temporary, then after the final timeout, only
2772 "retry timeout exceeded" was returned. Now it returns the full error as
2773 well as "retry timeout exceeded".

2843PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2844 function verify_get_ident() calls ip_connect() to connect a socket, but
2845 if the "connect()" function timed out, ip_connect() used to close the
2846 socket. However, verify_get_ident() also closes the socket later, and in
2847 between Exim writes to the log, which may get opened at this point. When
2848 the socket was closed in ip_connect(), the log could get the same file
2849 descriptor number as the socket. This naturally causes chaos. The fix is
2850 not to close the socket in ip_connect(); the socket should be closed by
2851 the function that creates it. There was only one place in the code where
2852 this was missing, in the iplookup router, which I don't think anybody now
2853 uses, but I've fixed it anyway.

2876
2877 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2878 string.
2879
2880 (3) Reset the variables that are obtained from the first argument of
2881 ${prvscheck and used in the second argument before leaving the code,
2882 because their memory is reclaimed, so using them afterwards may do
2883 silly things.
2884
2885 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2886 one (it's much easier than Tom thought :-).

2909PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2910 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2911 not being looked up in the rDNS to get a host name, Exim was showing the
2912 IP address twice in Received: lines, even though the IP addresses were
2913 identical. For example:
2914
2915 Received: from [1.2.3.4] (helo=[1.2.3.4])
2916
2917 However, if the real host name was known, it was omitting the HELO data
2918 if it matched the actual IP address. This has been tidied up so that it
2919 doesn't show the same IP address twice.

2945PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2947
2948 Auto-submitted: auto-generated
2949
2950 in the messages that it generates (bounce messages and others, such as
2951 warnings). In the case of bounce messages for non-SMTP mesages, there was
2952 also a typo: it was using "Auto_submitted" (underscore instead of
2953 hyphen). Since every message generated by Exim is necessarily in response
2954 to another message, thes have all been changed to:
2955
2956 Auto-Submitted: auto-replied
2957
2958 in accordance with these statements in the RFC:
2959
2960 The auto-replied keyword:
2961
2962 - SHOULD be used on messages sent in direct response to another
2963 message by an automatic process,
2964
2965 - MUST NOT be used on manually-generated messages,

2967 - MAY be used on Delivery Status Notifications (DSNs) and Message
2968 Disposition Notifications (MDNs),

3010 the IP address, check_host() was doing a simple string comparison with
3011 addresses acquired from the DNS when checking that the found name did
3012 have the original IP as one of its addresses. Since any found IPv6
3013 addresses are likely to be in abbreviated form, the comparison could
3014 fail. Luckily, there already exists a function for doing the comparison
3015 by converting both addresses to binary, so now that is used instead of
3016 the text comparison.

3134 authentication with radiusclient 0.4.9:
3135
3136 - Error returned from rc_read_config was caught wrongly
3137 - Username/password not passed on to radius server due to wrong length.
3138
3139 The presumption is that some radiusclient API changes for 4.51/PH/17
3140 were not taken care of correctly. The code is still untested by me (my
3141 Linux distribution still has 0.3.2 of radiusclient), but it was
3142 contributed by a Radius user.
3143
3144PH/24 When doing a callout, the value of $domain wasn't set correctly when
3145 expanding the "port" option of the smtp transport.

3153PH/25 Make $smtp_command_argument available after all SMTP commands. This means

PH
3157PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO
3158 commands, but it was not correctly comparing the address with the actual
3159 client host address. Thus, it would show the EHLO address in Received:
3160 header lines when this was not necessary.

PH
3164PH/28 Exim tries to create and chdir to its spool directory when it starts;
3165 it should be ignoring failures (because with -C, for example, it has lost
3166 privilege). It wasn't ignoring creation failures other than "already
3167 exists".

3184
3185PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
3186 Local/Makefile (with some defaults set). These are used in built scripts
3187 such as exicyclog, but they have never been used in the exim_install
3188 script (though there are many overriding facilities there). I have
3189 arranged that the exim_install script now takes note of these two
3190 settings.

3194PH/36 When a locally submitted message by a trusted user did not contain a
3195 From: header, and the sender address was obtained from -f or from an SMTP
3196 MAIL command, and the trusted user did not use -F to supply a sender
3197 name, $originator_name was incorrectly used when constructing a From:
3198 header. Furthermore, $originator_name was used for submission mode
3199 messages from external hosts without From: headers in a similar way,
3200 which is clearly wrong.

PH
3204PH/38 When log_selector = +received_sender was set, and the addition of the

3207 subsequently added.

3233PH/47 Added an interface to a fake DNS resolver for use by the new test suite,
3234 avoiding the need to install special zones in a real server. This is
3235 backwards compatible; if it can't find the fake resolver, it drops back.

3290PH/03 The warning log line about a condition test deferring for a "warn" verb
3291 was being output only once per connection, rather than after each

3295TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that

PH
3313PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3314 with the definition in sysexits.h (which is #included earlier).
3315 Fortunately, Exim does not actually use EX_OK. The code used to try to
3316 preserve the sysexits.h value, by assumimg that macro definitions were
3317 scanned for macro replacements. I have been disabused of this notion,
3318 so now the code just undefines EX_OK before #including unistd.h.

PH
3320PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3321 in the smtp transport. When a block could not be written in a single
3322 write() function, the timeout was being re-applied to each part-write.
3323 This seems wrong - if the receiver was accepting one byte at a time it
3324 would take for ever. The timeout is now adjusted when this happens. It
3325 doesn't have to be particularly precise.
