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.

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.

7f06582c
JH
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.

120 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
121 variables are renamed to proxy_{local,external}_{address,port}.

141 keys are given for lookup.

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.
fa01e4f8 155
4f6ae5c3
JH
156JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
157 and to use the domains and local_parts ACL conditions.
158
1bc460a6
JH
159JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
160 incorrectly not doubled on cutthrough transmission, hence seen as a
161 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 162 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
163 via the normal store-and-forward channel. This could result in duplicates
164 received - but deduplicating mailstores were liable to retain only the
165 initial truncated version.

178JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
179 either intentional arithmetic overflow during PRNG, or testing config-
180 induced overflows.

R
241 modifiers per server. Patch originally by <rommer@active.by>.
242
243JH/16 The spamd_address main option now supports a mixed list of local

282JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
283 Normally benign, it bites when the pair was led to by a CNAME;
284 modern usage is to not canoicalize the domain to a CNAME target
285 (and we were inconsistent anyway for A-only vs AAAA+A).

308Exim version 4.85
309-----------------
310TL/01 When running the test suite, the README says that variables such as
311 no_msglog_check are global and can be placed anywhere in a specific
312 test's script, however it was observed that placement needed to be near
313 the beginning for it to behave that way. Changed the runtest perl
314 script to read through the entire script once to detect and set these
315 variables, reset to the beginning of the script, and then run through
316 the script parsing/test process like normal.

343JH/05 Fix results-pipe from transport process. Several recipients, combined
344 with certificate use, exposed issues where response data items split
345 over buffer boundaries were not parsed properly. This eventually
346 resulted in duplicates being sent. This issue only became common enough
347 to notice due to the introduction of conection certificate information,
348 the item size being so much larger. Found and fixed by Wolfgang Breyha.

420TF/01 Correctly close the server side of TLS when forking for delivery.
421
422 When a message was received over SMTP with TLS, Exim failed to clear up
423 the incoming connection properly after forking off the child process to
424 deliver the message. In some situations the subsequent outgoing
425 delivery connection happened to have the same fd number as the incoming
426 connection previously had. Exim would try to use TLS and fail, logging
427 a "Bad file descriptor" error.

673TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
674
675 When a queue runner is handling a message, Exim first routes the
676 recipient addresses, during which it prunes them based on the retry
677 hints database. After that it attempts to deliver the message to
678 any remaining recipients. It then updates the hints database using
679 the retry rules.
680
681 So if a recipient address works intermittently, it can get repeatedly
682 deferred at routing time. The retry hints record remains fresh so the
683 address never reaches the final cutoff time.
684
685 This is a fairly common occurrence when a user is bumping up against
686 their storage quota. Exim had some logic in its local delivery code
687 to deal with this. However it did not apply to per-recipient defers
688 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
689
1ddeb334
TF
690 This change adds a proper retry rule check during routing so that the
691 final cutoff time is checked against the message's age. We only do
692 this check if there is an address retry record and there is not a
693 domain retry record; this implies that previous attempts to handle
694 the address had the retry_use_local_parts option turned on. We use
695 this as an approximation for the destination being like a local
696 delivery, as in LMTP.
67bd1ab3
TF
697
698 I suspect this new check makes the old local delivery cutoff check
699 redundant, but I have not verified this so I left the code in place.

739 the body content is received and before the acl_smtp_data ACL.
740 The client is controlled by bolth of: a hosts_try_prdr option
741 on the smtp transport, and the server advertisement.

1021TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1022 lock up or crash if it happened to be inside a call to libc when it
1023 got a SIGUSR1 from exiwhat.
1024
1025 The SIGUSR1 handler appends the current process status to the process
1026 log which is later printed by exiwhat. It used to use the general
1027 purpose logging code to do this, but several functions it calls are
1028 not safe for signals.
1029
1030 The new output code in the SIGUSR1 handler is specific to the process
1031 log, and simple enough that it's easy to inspect for signal safety.
1032 Removing some special cases also simplifies the general logging code.
1033 Removing the spurious timestamps from the process log simplifies
1034 exiwhat.

TF
1036TF/04 Improved ratelimit ACL condition.
1037
1038 The /noupdate option has been deprecated in favour of /readonly which
1039 has clearer semantics. The /leaky, /strict, and /readonly update modes
1040 are mutually exclusive. The update mode is no longer included in the
1041 database key; it just determines when the database is updated. (This
1042 means that when you upgrde Exim will forget old rate measurements.)
1043
1044 Exim now checks that the per_* options are used with an update mode that
1045 makes sense for the current ACL. For example, when Exim is processing a
1046 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1047 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1048 must specify per_mail/readonly. If you omit the update mode it defaults to
1049 /leaky where that makes sense (as before) or /readonly where required.
1050
1051 The /noupdate option is now undocumented but still supported for
1052 backwards compatibility. It is equivalent to /readonly except that in
1053 ACLs where /readonly is required you may specify /leaky/noupdate or
1054 /strict/noupdate which are treated the same as /readonly.
1055
1056 A useful new feature is the /count= option. This is a generalization
1057 of the per_byte option, so that you can measure the throughput of other
1058 aggregate values. For example, the per_byte option is now equivalent
1059 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1060
1061 The per_rcpt option has been generalized using the /count= mechanism
1062 (though it's more complicated than the per_byte equivalence). When it is
1063 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1064 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1065 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1066 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1067 Note that using per_rcpt with a non-readonly update mode in more than
1068 one ACL will cause the recipients to be double-counted. (The per_mail
1069 and per_byte options don't have this problem.)
1070
1071 The handling of very low rates has changed slightly. If the computed rate
1072 is less than the event's count (usually one) then this event is the first
1073 after a long gap. In this case the rate is set to the same as this event's
1074 count, so that the first message of a spam run is counted properly.
1075
1076 The major new feature is a mechanism for counting the rate of unique
1077 events. The new per_addr option counts the number of different
1078 recipients that someone has sent messages to in the last time period. It
1079 behaves like per_rcpt if all the recipient addresses are different, but
1080 duplicate recipient addresses do not increase the measured rate. Like
1081 the /count= option this is a general mechanism, so the per_addr option
1082 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1083 example, measure the rate that a client uses different sender addresses
1084 with the options per_mail/unique=$sender_address. There are further
1085 details in the main documentation.

1635 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1636 were called 'true' and it seems that C99 defines that as a reserved

1638 not include C99-style headers which use bools without triggering

1655-----------------
1656
1657PH/01 Another patch from the Sieve maintainer.
1658
6a3bceb1
PH
1659PH/02 When an IPv6 address is converted to a string for single-key lookup
1660 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1661 dots are used instead of colons so that keys in lsearch files need not
1662 contain colons. This was done some time before quoting was made available
1663 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1664 (notated using the quote facility) so as to distinguish them from IPv4
1665 keys. This meant that lookups for IP addresses in host lists did not work
1666 for iplsearch lookups.
1667
1668 This has been fixed by arranging for IPv6 addresses to be expressed with
1669 colons if the lookup type is iplsearch. This is not incompatible, because
1670 previously such lookups could never work.
1671
1672 The situation is now rather anomolous, since one *can* have colons in
1673 ordinary lsearch keys. However, making the change in all cases is
1674 incompatible and would probably break a number of configurations.

MH
1679MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1680 conversion specification without a maximum field width, thereby enabling
1681 a rogue spamd server to cause a buffer overflow. While nobody in their
1682 right mind would setup Exim to query an untrusted spamd server, an
1683 attacker that gains access to a server running spamd could potentially
1684 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1689MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1690 a directory entry by the name of the lookup key. Previously, if a
1691 symlink pointed to a non-existing file or a file in a directory that
1692 Exim lacked permissions to read, a lookup for a key matching that
1693 symlink would fail. Now it is enough that a matching directory entry
1694 exists, symlink or not. (Bugzilla 503.)

1771 if a client was not listed at all, or was listed with a value other than
1772 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1773 the condition was not true (as it should be), so access was not denied.

PH
1877PH/29 SMTP synchronization checks are implemented when a command is read -
1878 there is a check that no more input is waiting when there shouldn't be
1879 any. However, for some commands, a delay in an ACL can mean that it is
1880 some time before the response is written. In this time, more input might
1881 arrive, invalidly. So now there are extra checks after an ACL has run for
1882 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1883 pipelining has not been advertised.

PH
1895PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1896 Exim which did not show up earlier: it was assuming that a call to
1897 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1898 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1899 was a macro that became an assignment, so it seemed to work. This has
1900 changed to a proper function call with a void return, hence the compile
1901 error. Exim's code has been fixed.

1939 with PIPELINING or a stupid MUA), the error message that was given to the
1940 RCPT commands is included in the rejection of the DATA command. This is

58eb016e 1956PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1957 the response to the final '.' that terminates a message, but only in the
1958 case where the client has not sent further data following the '.'
1959 (unfortunately, this is allowed). However, in many cases there won't be
1960 any further data because there won't be any more messages to send. A call
1961 to select() can be used: if it shows that the input is "ready", there is
1962 either input waiting, or the socket has been closed. An attempt to read
1963 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1964 would have sent an OK response which the client would never have see.

1973-----------------
1974
1975PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1976 fixed by 4.65/MH/01 (is this a record?) are fixed:
1977
1978 (i) An empty string was always treated as zero by the numeric comparison
1979 operators. This behaviour has been restored.
1980
1981 (ii) It is documented that the numeric comparison operators always treat
1982 their arguments as decimal numbers. This was broken in that numbers
1983 starting with 0 were being interpreted as octal.
1984
1985 While fixing these problems I realized that there was another issue that
1986 hadn't been noticed. Values of message_size_limit (both the global option
1987 and the transport option) were treated as octal if they started with 0.
1988 The documentation was vague. These values are now always treated as
1989 decimal, and I will make that clear in the documentation.

2003PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
2004 child addresses, Exim now panics and dies. Previously, because the count
2005 is held in a short int, deliveries were likely to be lost. As such a
2006 large number of recipients for a single message is ridiculous
2007 (performance will be very, very poor), I have chosen to impose a limit
2008 rather than extend the field.

2014TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2015 leftover -K file (the existence of which was triggered by #402).
2016 While we were at it, introduced process PID as part of the -K
2017 filename. This should rule out race conditions when creating
2018 these files.

2020TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
2021 processing considerably. Previous code took too long for large mails,
2022 triggering a timeout which in turn triggers #401.
2023
2024TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2025 in the DK code in transports.c. sendfile() is not really portable,
2026 hence the _LINUX specificness.

2028TF/01 In the add_headers option to the mail command in an Exim filter,

2031 in the field name.

PH
2033PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2034 callout verification, Exim cached a "reject" for the entire domain. This
2035 is correct for most verifications, but it is not correct for a recipient
2036 verification with use_sender or use_postmaster set, because in that case
2037 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2038 case of MAIL FROM:<> rejection from other early rejections (e.g.
2039 rejection of HELO). When verifying a recipient using a non-null MAIL
2040 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2041 Whatever the result of the callout, the value of the domain cache is
2042 left unchanged (for any other kind of callout, getting as far as trying
2043 RCPT means that the domain itself is ok).

2077PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2078 hostname. This is wrong, because it relates to the incoming message (and
2079 probably the interface on which it is arriving) and not to the outgoing
2080 callout (which could be using a different interface). This has been
2081 changed to use the value of the helo_data option from the smtp transport
2082 instead - this is what is used when a message is actually being sent. If
2083 there is no remote transport (possible with a router that sets up host
2084 addresses), $smtp_active_hostname is used.

14aa5a05 2086PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2087 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2088 (a) The code assumed that strncpy() returns a negative number on buffer
2089 overflow, which isn't the case. Replaced with Exim's string_format()
2090 function.
2091 (b) There were several signed/unsigned issues. I just did the minimum
2092 hacking in of casts. There is scope for a larger refactoring.
2093 (c) The code used strcasecmp() which is not a standard C function.
2094 Replaced with Exim's strcmpic() function.
2095 (d) The code set only $1; it now sets $auth1 as well.
2096 (e) A simple test gave the error "authentication client didn't specify
2097 service in request". It would seem that Dovecot has changed its
2098 interface. Fortunately there's a specification; I followed it and
2099 changed what the client sends and it appears to be working now.

2104PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2105 address A is aliased to B and C, where B exists and C does not. Without
2106 -v the output is "A verified" because verification stops after a
2107 successful redirection if more than one address is generated. However,
2108 with -v the child addresses are also verified. Exim was outputting "A
2109 failed to verify" and then showing the successful verification for C,
2110 with its parentage. It now outputs "B failed to verify", showing B's
2111 parentage before showing the successful verification of C.

2114 look up a TXT record in a specific list after matching in a combined
2115 list.
2116
322050c2
PH
2117PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2118 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2119 they consult the DNS. I had assumed they would set it the way they
2120 wanted; and indeed my experiments on Linux seem to show that in some
2121 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2122 To be on the safe side, however, I have now made the interface to
2123 host_find_byname() similar to host_find_bydns(), with an argument
2124 containing the DNS resolver options. The host_find_byname() function now
2125 sets these options at its start, just as host_find_bydns() does. The smtp
2126 transport options dns_qualify_single and dns_search_parents are passed to
2127 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2128 of host_find_byname() use the default settings of RES_DEFNAMES
2129 (qualify_single) but not RES_DNSRCH (search_parents).

2131PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2132 spool_read_header() do less string testing, by means of a preliminary
2133 switch on the second character of optional "-foo" lines. (This is
2134 overdue, caused by the large number of possibilities that now exist.
2135 Originally there were few.) While I was there, I also converted the
2136 str(n)cmp tests so they don't re-test the leading "-" and the first
2137 character, in the hope this might squeeze out yet more improvement.

PH
2139PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2140 flag allowing group syntax was set by the header_syntax check but not
2141 turned off, possible causing trouble later; (2) The flag was not being
2142 set at all for the header_verify test, causing "group"-style headers to
2143 be rejected. I have now set it in this case, and also caused header_
2144 verify to ignore an empty address taken from a group. While doing this, I
2145 came across some other cases where the code for allowing group syntax
2146 while scanning a header line wasn't quite right (mostly, not resetting
2147 the flag correctly in the right place). These bugs could have caused
2148 trouble for malformed header lines. I hope it is now all correct.

PH
2150PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2151 with the "reply" argument non-NULL. The code, however (which originally
2152 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2153 but it didn't always do it. This confused somebody who was copying the
2154 code for some other use. I have removed all the tests.

411ef850
PH
2156PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2157 feature that was used to support insecure browsers during the U.S. crypto
2158 embargo. It requires special client support, and Exim is probably the
2159 only MTA that supported it -- and would never use it because real RSA is
2160 always available. This code has been removed, because it had the bad
2161 effect of slowing Exim down by computing (never used) parameters for the
2162 RSA_EXPORT functionality.
2163
7befa435
PH
2164PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2165 authenticator to fail if there's a tab character in the incoming data
2166 (there should never be unless someone is messing about, as it's supposed
2167 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2168 if the connection is using TLS or if the remote IP is the same as the
2169 local IP, and the "valid-client-cert option" if a client certificate has
2170 been verified.

PH
2201
2202PH/30 Exim was sometimes attempting to deliver messages that had suffered
2203 address errors (4xx response to RCPT) over the same connection as other
2204 messages routed to the same hosts. Such deliveries are always "forced",
2205 so retry times are not inspected. This resulted in far too many retries
2206 for the affected addresses. The effect occurred only when there were more
2207 hosts than the hosts_max_try setting in the smtp transport when it had
2208 the 4xx errors. Those hosts that it had tried were not added to the list
2209 of hosts for which the message was waiting, so if all were tried, there
2210 was no problem. Two fixes have been applied:
2211
2212 (i) If there are any address or message errors in an SMTP delivery, none
2213 of the hosts (tried or untried) are now added to the list of hosts
2214 for which the message is waiting, so the message should not be a
2215 candidate for sending over the same connection that was used for a
2216 successful delivery of some other message. This seems entirely
2217 reasonable: after all the message is NOT "waiting for some host".
2218 This is so "obvious" that I'm not sure why it wasn't done
2219 previously. Hope I haven't missed anything, but it can't do any
2220 harm, as the worst effect is to miss an optimization.
2221
2222 (ii) If, despite (i), such a delivery is accidentally attempted, the
2223 routing retry time is respected, so at least it doesn't keep
2224 hammering the server.

PH
2239PH/35 The error "getsockname() failed: connection reset by peer" was being
2240 written to the panic log as well as the main log, but it isn't really
2241 panic-worthy as it just means the connection died rather early on. I have
2242 removed the panic log writing for the ECONNRESET error when getsockname()
2243 fails.
2244
48c7f9e2
PH
2245PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2246 runs only) independently of the message's sender address. This meant
2247 that, if the 4xx error was in fact related to the sender, a different
2248 message to the same recipient with a different sender could confuse
2249 things. In particualar, this can happen when sending to a greylisting
2250 server, but other circumstances could also provoke similar problems.
2251 I have changed the default so that the retry time for these errors is now
2252 based a combination of the sender and recipient addresses. This change
2253 can be overridden by setting address_retry_include_sender=false in the
2254 smtp transport.

2525 tcp-wrappers gives "deny", whereas what one would like would be some
2526 kind of temporary error. A kludge has been added to help with this.
2527 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2528 554 error is used if errno is still zero or contains ENOENT (which occurs
2529 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2570 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2615 autoreply, Exim could try to deliver to a non-existent relative file

2651 Instead, it always explicitly searches for A/AAAA records. This avoids
2652 major problems that occur when a DNS server includes only records of one
2653 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2654 fixed another bug: if SRV records were looked up and the corresponding
2655 address records were *not* found in the additional section, the port
2656 values from the SRV records were lost.

PH
2666PH/19 When calculating a retry time, Exim used to measure the "time since
2667 failure" by looking at the "first failed" field in the retry record. Now
2668 it does not use this if it is later than than the arrival time of the
2669 message. Instead it uses the arrival time. This makes for better
2670 behaviour in cases where some deliveries succeed, thus re-setting the
2671 "first failed" field. An example is a quota failure for a huge message
2672 when small messages continue to be delivered. Without this change, the
2673 "time since failure" will always be short, possible causing more frequent
2674 delivery attempts for the huge message than are intended.

PH
2771PH/42 The content-scanning code uses fopen() to create files in which to put
2772 message data. Previously it was not paying any attention to the mode of
2773 the files. Exim runs with umask(0) because the rest of the code creates
2774 files with open(), and sets the required mode explicitly. Thus, these
2775 files were ending up world-writeable. This was not a big issue, because,
2776 being within the spool directory, they were not world-accessible. I have
2777 created a function called modefopen, which takes an additional mode
2778 argument. It sets umask(777), creates the file, chmods it to the required
2779 mode, then resets the umask. All the relevant calls to fopen() in the
2780 content scanning code have been changed to use this function.

2788PH/45 When the plaintext authenticator is running as a client, the server's
2789 challenges are checked to ensure they are valid base64 strings. By
2790 default, the authentication attempt is cancelled if an invalid string is
2791 received. Setting client_ignore_invalid_base64 true ignores these errors.
2792 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2793 they are received. Thus, the responses can be made to depend on the
2794 challenges. If an invalid string is ignored, an empty string is placed in
2795 the variable.

2809 of files (along with the size), even though it did not need this

PH
2815PH/52 Two bugs concerned with error handling when the smtp transport is
2816 used in LMTP mode:
2817
2818 (i) Exim was not creating retry information for temporary errors given
2819 for individual recipients after the DATA command when the smtp transport
2820 was used in LMTP mode. This meant that they could be retried too
2821 frequently, and not timed out correctly.
2822
2823 (ii) Exim was setting the flag that allows error details to be returned
2824 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2825 recipients that were returned after the DATA command.
2826
2827PH/53 This is related to PH/52, but is more general: for any failing address,
2828 when detailed error information was permitted to be returned to the
2829 sender, but the error was temporary, then after the final timeout, only
2830 "retry timeout exceeded" was returned. Now it returns the full error as
2831 well as "retry timeout exceeded".

2887PH/68 The bounce_return_message and bounce_return_body options were not being

2889 In particular, this applied to messages rejected by the ACL. This bug has
2890 been fixed. However, if bounce_return_message is true and bounce_return_
2891 body is false, the headers that are returned for a non-SMTP message
2892 include only those that have been read before the error was detected.

2895PH/69 The HTML version of the specification is now built in a directory called

PH
2901PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2902 function verify_get_ident() calls ip_connect() to connect a socket, but
2903 if the "connect()" function timed out, ip_connect() used to close the
2904 socket. However, verify_get_ident() also closes the socket later, and in
2905 between Exim writes to the log, which may get opened at this point. When
2906 the socket was closed in ip_connect(), the log could get the same file
2907 descriptor number as the socket. This naturally causes chaos. The fix is
2908 not to close the socket in ip_connect(); the socket should be closed by
2909 the function that creates it. There was only one place in the code where
2910 this was missing, in the iplookup router, which I don't think anybody now
2911 uses, but I've fixed it anyway.

2930PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2931
2932 (1) Generate an error if the third argument for the ${prvs expansion is
2933 not a single digit.
2934
2935 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2936 string.
2937
2938 (3) Reset the variables that are obtained from the first argument of
2939 ${prvscheck and used in the second argument before leaving the code,
2940 because their memory is reclaimed, so using them afterwards may do
2941 silly things.
2942
2943 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2944 one (it's much easier than Tom thought :-).
2945
2946 (5) Because of (4), we can now allow for the use of $prvscheck_result
2947 inside the third argument.

2957 quoted in the delivery log line, like this:
2958
2959 => >A.N.Other <ano@some.domain> <original@ddress> ...
2960
2961 This has been changed so that it extracts the operative address. There
2962 may be more than one such address. If so, they are comma-separated, like
2963 this:

PH
2967PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2968 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2969 not being looked up in the rDNS to get a host name, Exim was showing the
2970 IP address twice in Received: lines, even though the IP addresses were
2971 identical. For example:
2972
2973 Received: from [1.2.3.4] (helo=[1.2.3.4])
2974
2975 However, if the real host name was known, it was omitting the HELO data
2976 if it matched the actual IP address. This has been tidied up so that it
2977 doesn't show the same IP address twice.

2979PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
3003PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3004 Electronic Mail") by including:
3005
3006 Auto-submitted: auto-generated
3007
3008 in the messages that it generates (bounce messages and others, such as
3009 warnings). In the case of bounce messages for non-SMTP mesages, there was
3010 also a typo: it was using "Auto_submitted" (underscore instead of
3011 hyphen). Since every message generated by Exim is necessarily in response
3012 to another message, thes have all been changed to:
3013
3014 Auto-Submitted: auto-replied
3015
3016 in accordance with these statements in the RFC:
3017
3018 The auto-replied keyword:
3019
3020 - SHOULD be used on messages sent in direct response to another
3021 message by an automatic process,
3022

3066PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

3068 the IP address, check_host() was doing a simple string comparison with
3069 addresses acquired from the DNS when checking that the found name did
3070 have the original IP as one of its addresses. Since any found IPv6
3071 addresses are likely to be in abbreviated form, the comparison could
3072 fail. Luckily, there already exists a function for doing the comparison
3073 by converting both addresses to binary, so now that is used instead of
3074 the text comparison.

3158PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3159 only if the host matched helo_try_verify_hosts, which caused the
3160 verification to occur when the EHLO/HELO command was issued. The ACL just
3161 tested the remembered result. Now, if a previous verification attempt has
3162 not happened, "verify = helo" does it there and then.

3191PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3192 authentication with radiusclient 0.4.9:
3193
3194 - Error returned from rc_read_config was caught wrongly
3195 - Username/password not passed on to radius server due to wrong length.
3196
3197 The presumption is that some radiusclient API changes for 4.51/PH/17
3198 were not taken care of correctly. The code is still untested by me (my
3199 Linux distribution still has 0.3.2 of radiusclient), but it was

3253 From: header, and the sender address was obtained from -f or from an SMTP
3254 MAIL command, and the trusted user did not use -F to supply a sender
3255 name, $originator_name was incorrectly used when constructing a From:

3257 messages from external hosts without From: headers in a similar way,
3258 which is clearly wrong.
