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.

JH
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.

57JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.

62

JH
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
376d2ec0
JH
67 ${quote_pgsql:<string>} operator.
68

JH
69JH/13 Bug 1708: avoid misaligned access in cached lookup.
70
858e91c2
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.
73
74JH/15 Bug 1712: Introduce $prdr_requested flag variable
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.
104

JH
105JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
106
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.

116 by defining SUPPORT_SOCKS.
74f150bf 117
cee5f132
JH
118JH/26 Move PROXY support from Experimental to mainline, enabled for a build
119 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
120 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
121 variables are renamed to proxy_{local,external}_{address,port}.
cee5f132 122

135 cached by the daemon.

de78e2d5
JH
137JH/32 Move Redis support from Experimental to mainline, enabled for a build
138 by defining LOOKUP_REDIS. The libhiredis library is required.
139
379ba7d0
JH
140JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
141 keys are given for lookup.
142
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/02 The smtp transport option "multi_domain" is now expanded.
179
ad07e9ad

180JH/03 The smtp transport now requests PRDR by default, if the server offers
181 it.
182
01a4a5c5 183JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 184 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
185 can be used to disable this per-host. The build option
186 EXPERIMENTAL_CERTNAMES is withdrawn.
187
cb1d7830 188JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 189 default to the word "system" to access the system default CA bundle.

JH
190 For GnuTLS, only version 3.0.20 or later.
191
610ff438 192JH/06 Verification of the server certificate for a TLS connection is now tried

193 (but not required) by default. The verification status is now logged by
194 default, for both outbound TLS and client-certificate supplying inbound
195 TLS connections
610ff438 196

200JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
201 Status Notification (bounce) messages are now MIME format per RFC 3464.
202 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
203 under the control of the dsn_advertise_hosts option, and routers may
204 have a dsn_lasthop option.
205

dc7b3d36 225 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
226 modifiers per server. Patch originally by <rommer@active.by>.
227
228JH/16 The spamd_address main option now supports a mixed list of local
2aad5761

267JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
268 Normally benign, it bites when the pair was led to by a CNAME;
269 modern usage is to not canoicalize the domain to a CNAME target
270 (and we were inconsistent anyway for A-only vs AAAA+A).

293Exim version 4.85
294-----------------
295TL/01 When running the test suite, the README says that variables such as
296 no_msglog_check are global and can be placed anywhere in a specific
297 test's script, however it was observed that placement needed to be near
298 the beginning for it to behave that way. Changed the runtest perl
299 script to read through the entire script once to detect and set these
300 variables, reset to the beginning of the script, and then run through
301 the script parsing/test process like normal.

328JH/05 Fix results-pipe from transport process. Several recipients, combined
329 with certificate use, exposed issues where response data items split
330 over buffer boundaries were not parsed properly. This eventually
331 resulted in duplicates being sent. This issue only became common enough
332 to notice due to the introduction of conection certificate information,
333 the item size being so much larger. Found and fixed by Wolfgang Breyha.

aec45841 345 and $event_defer_errno. There is a new variable $verify_mode, usable in

406
407 When a message was received over SMTP with TLS, Exim failed to clear up
408 the incoming connection properly after forking off the child process to
409 deliver the message. In some situations the subsequent outgoing
410 delivery connection happened to have the same fd number as the incoming
411 connection previously had. Exim would try to use TLS and fail, logging
412 a "Bad file descriptor" error.

658TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
659
660 When a queue runner is handling a message, Exim first routes the
661 recipient addresses, during which it prunes them based on the retry
662 hints database. After that it attempts to deliver the message to
663 any remaining recipients. It then updates the hints database using
664 the retry rules.
665
666 So if a recipient address works intermittently, it can get repeatedly
667 deferred at routing time. The retry hints record remains fresh so the
668 address never reaches the final cutoff time.
669
670 This is a fairly common occurrence when a user is bumping up against
671 their storage quota. Exim had some logic in its local delivery code
672 to deal with this. However it did not apply to per-recipient defers
673 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
674
1ddeb334
TF
675 This change adds a proper retry rule check during routing so that the
676 final cutoff time is checked against the message's age. We only do
677 this check if there is an address retry record and there is not a
678 domain retry record; this implies that previous attempts to handle
679 the address had the retry_use_local_parts option turned on. We use
680 this as an approximation for the destination being like a local
681 delivery, as in LMTP.
67bd1ab3
TF
682
683 I suspect this new check makes the old local delivery cutoff check
684 redundant, but I have not verified this so I left the code in place.

1006TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1007 lock up or crash if it happened to be inside a call to libc when it
1008 got a SIGUSR1 from exiwhat.
1009
1010 The SIGUSR1 handler appends the current process status to the process
1011 log which is later printed by exiwhat. It used to use the general
1012 purpose logging code to do this, but several functions it calls are
1013 not safe for signals.
1014
1015 The new output code in the SIGUSR1 handler is specific to the process
1016 log, and simple enough that it's easy to inspect for signal safety.
1017 Removing some special cases also simplifies the general logging code.
1018 Removing the spurious timestamps from the process log simplifies
1019 exiwhat.

TF
1021TF/04 Improved ratelimit ACL condition.
1022
1023 The /noupdate option has been deprecated in favour of /readonly which
1024 has clearer semantics. The /leaky, /strict, and /readonly update modes
1025 are mutually exclusive. The update mode is no longer included in the
1026 database key; it just determines when the database is updated. (This
1027 means that when you upgrde Exim will forget old rate measurements.)
1028
1029 Exim now checks that the per_* options are used with an update mode that
1030 makes sense for the current ACL. For example, when Exim is processing a
1031 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1032 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1033 must specify per_mail/readonly. If you omit the update mode it defaults to
1034 /leaky where that makes sense (as before) or /readonly where required.
1035
1036 The /noupdate option is now undocumented but still supported for
1037 backwards compatibility. It is equivalent to /readonly except that in
1038 ACLs where /readonly is required you may specify /leaky/noupdate or
1039 /strict/noupdate which are treated the same as /readonly.
1040
1041 A useful new feature is the /count= option. This is a generalization
1042 of the per_byte option, so that you can measure the throughput of other
1043 aggregate values. For example, the per_byte option is now equivalent
1044 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1045
1046 The per_rcpt option has been generalized using the /count= mechanism
1047 (though it's more complicated than the per_byte equivalence). When it is
1048 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1049 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1050 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1051 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1052 Note that using per_rcpt with a non-readonly update mode in more than
1053 one ACL will cause the recipients to be double-counted. (The per_mail
1054 and per_byte options don't have this problem.)
1055
1056 The handling of very low rates has changed slightly. If the computed rate
1057 is less than the event's count (usually one) then this event is the first
1058 after a long gap. In this case the rate is set to the same as this event's
1059 count, so that the first message of a spam run is counted properly.
1060
1061 The major new feature is a mechanism for counting the rate of unique
1062 events. The new per_addr option counts the number of different
1063 recipients that someone has sent messages to in the last time period. It
1064 behaves like per_rcpt if all the recipient addresses are different, but
1065 duplicate recipient addresses do not increase the measured rate. Like
1066 the /count= option this is a general mechanism, so the per_addr option
1067 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1068 example, measure the rate that a client uses different sender addresses
1069 with the options per_mail/unique=$sender_address. There are further
1070 details in the main documentation.

1619
1620 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1621 were called 'true' and it seems that C99 defines that as a reserved
1622 keyword to be used with 'bool' variable types. That means you could
1623 not include C99-style headers which use bools without triggering
1624 build errors in sieve.c.

1639Exim version 4.68
1640-----------------
1641
1642PH/01 Another patch from the Sieve maintainer.
1643
6a3bceb1
PH
1644PH/02 When an IPv6 address is converted to a string for single-key lookup
1645 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1646 dots are used instead of colons so that keys in lsearch files need not
1647 contain colons. This was done some time before quoting was made available
1648 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1649 (notated using the quote facility) so as to distinguish them from IPv4
1650 keys. This meant that lookups for IP addresses in host lists did not work
1651 for iplsearch lookups.
1652
1653 This has been fixed by arranging for IPv6 addresses to be expressed with
1654 colons if the lookup type is iplsearch. This is not incompatible, because
1655 previously such lookups could never work.
1656
1657 The situation is now rather anomolous, since one *can* have colons in
1658 ordinary lsearch keys. However, making the change in all cases is
1659 incompatible and would probably break a number of configurations.

TK
1661TK/01 Change PRVS address formatting scheme to reflect latests BATV draft

MH
1664MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1665 conversion specification without a maximum field width, thereby enabling
1666 a rogue spamd server to cause a buffer overflow. While nobody in their
1667 right mind would setup Exim to query an untrusted spamd server, an
1668 attacker that gains access to a server running spamd could potentially
1669 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1674MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1675 a directory entry by the name of the lookup key. Previously, if a
1676 symlink pointed to a non-existing file or a file in a directory that
1677 Exim lacked permissions to read, a lookup for a key matching that
1678 symlink would fail. Now it is enough that a matching directory entry
1679 exists, symlink or not. (Bugzilla 503.)

1719PH/18 If a system quota error occurred while trying to create the file for
1720 a maildir delivery, the message "Mailbox is full" was not appended to the

1722 only to a quota excession during the actual writing of the file.

ddea74fa 1724PH/19 It seems that peer DN values may contain newlines (and other non-printing

1750 issue a MAIL command.
1751
431b7361
PH
1752PH/02 In an ACL statement such as
1753
1754 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1755
1756 if a client was not listed at all, or was listed with a value other than
1757 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1758 the condition was not true (as it should be), so access was not denied.
1759 The bug was that the ! inversion was incorrectly passed on to the second
1760 item. This has been fixed.
1761

1763 = and & when the dns lookup returns more than one IP address.

PH
1768PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_

1776 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
1777 including adding "make clean"; (3) Added -fPIC when compiling the test
1778 dynamically loaded module, to get rid of a warning.

0e8a9471
MH
1780MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
1781 message fails, move_frozen_messages = true and ignore_bounce_errors_after
1782 = 0s. The bug is otherwise harmless.
1783
f0872424
PH
1784PH/07 There was a bug in the dovecot authenticator such that the value of
1785 $auth1 could be overwritten, and so not correctly preserved, after a
1786 successful authentication. This usually meant that the value preserved by
1787 the server_setid option was incorrect.

PH
1793PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1794 run for batched SMTP input. It is now run at the start of every message
1795 in the batch. While fixing this I discovered that the process information
1796 (output by running exiwhat) was not always getting set for -bs and -bS
1797 input. This is fixed, and it now also says "batched" for BSMTP.

5a11a7b4
PH
1848PH/27 When a message times out after an over-quota error from an Exim-imposed
1849 quota, the bounce message says "mailbox is full". This message was not
1850 being given when it was a system quota that was exceeded. It now should
1851 be the same.
1852
0e20aff9
MH
1853MH/03 Made $recipients available in local_scan(). local_scan() already has
1854 better access to the recipient list through recipients_list[], but
1855 $recipients can be useful in postmaster-provided expansion strings.
1856
ca86f471
PH
1857PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1858 in the case of a MAIL command with additional options following the

1860 were accidentally chopped off.
1861
a14e5636
PH
1862PH/29 SMTP synchronization checks are implemented when a command is read -
1863 there is a check that no more input is waiting when there shouldn't be
1864 any. However, for some commands, a delay in an ACL can mean that it is
1865 some time before the response is written. In this time, more input might
1866 arrive, invalidly. So now there are extra checks after an ACL has run for
1867 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1868 pipelining has not been advertised.

1878 reported on Solaris.
1879
58c01c94
PH
1880PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1881 Exim which did not show up earlier: it was assuming that a call to
1882 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1883 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1884 was a macro that became an assignment, so it seemed to work. This has
1885 changed to a proper function call with a void return, hence the compile
1886 error. Exim's code has been fixed.

1897 "Completed" line in the log. When some messages of this type were
1898 selected by exigrep, they were listed as "not completed". Others were

c456d9bb
PH
1902PH/38 The host_find_failed option in the manualroute router can now be set

cd9868ec
PH
1907PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1908 homing or because of multiple MX records with /mx) generated more than
1909 one IP address, and the following item turned out to be the local host,
1910 all the secondary addresses of the first item were incorrectly removed
1911 from the list, along with the local host and any following hosts (which
1912 is what is supposed to happen).
1913
ebeaf996
PH
1914PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1915 whoever called Exim into the -H file. In the case of the daemon it was
1916 behaving confusingly. When first started, it used values for whoever
1917 started the daemon, but after a SIGHUP it used the Exim user (because it
1918 calls itself on a restart). I have changed the code so that it now always
1919 uses the Exim user.

2679d413
PH
1921PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1922 message are rejected with the same error (e.g. no authentication or bad
1923 sender address), and a DATA command is nevertheless sent (as can happen
1924 with PIPELINING or a stupid MUA), the error message that was given to the
1925 RCPT commands is included in the rejection of the DATA command. This is
1926 intended to be helpful for MUAs that show only the final error to their
1927 users.

1946 to select() can be used: if it shows that the input is "ready", there is
1947 either input waiting, or the socket has been closed. An attempt to read
1948 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1949 would have sent an OK response which the client would never have see.

1958-----------------
1959
1960PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1961 fixed by 4.65/MH/01 (is this a record?) are fixed:
1962
1963 (i) An empty string was always treated as zero by the numeric comparison
1964 operators. This behaviour has been restored.
1965
1966 (ii) It is documented that the numeric comparison operators always treat
1967 their arguments as decimal numbers. This was broken in that numbers
1968 starting with 0 were being interpreted as octal.
1969
1970 While fixing these problems I realized that there was another issue that
1971 hadn't been noticed. Values of message_size_limit (both the global option
1972 and the transport option) were treated as octal if they started with 0.
1973 The documentation was vague. These values are now always treated as
1974 decimal, and I will make that clear in the documentation.

1988PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1989 child addresses, Exim now panics and dies. Previously, because the count
1990 is held in a short int, deliveries were likely to be lost. As such a
1991 large number of recipients for a single message is ridiculous
1992 (performance will be very, very poor), I have chosen to impose a limit
1993 rather than extend the field.

1999TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2000 leftover -K file (the existence of which was triggered by #402).
2001 While we were at it, introduced process PID as part of the -K
2002 filename. This should rule out race conditions when creating
2003 these files.

2008
2009TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
2010 in the DK code in transports.c. sendfile() is not really portable,

2016 in the field name.

PH
2018PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2019 callout verification, Exim cached a "reject" for the entire domain. This
2020 is correct for most verifications, but it is not correct for a recipient
2021 verification with use_sender or use_postmaster set, because in that case
2022 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2023 case of MAIL FROM:<> rejection from other early rejections (e.g.
2024 rejection of HELO). When verifying a recipient using a non-null MAIL
2025 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2026 Whatever the result of the callout, the value of the domain cache is
2027 left unchanged (for any other kind of callout, getting as far as trying
2028 RCPT means that the domain itself is ok).

2062PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2064 probably the interface on which it is arriving) and not to the outgoing
2065 callout (which could be using a different interface). This has been
2066 changed to use the value of the helo_data option from the smtp transport
2067 instead - this is what is used when a message is actually being sent. If
2068 there is no remote transport (possible with a router that sets up host
2069 addresses), $smtp_active_hostname is used.

7befa435 2072 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2073 (a) The code assumed that strncpy() returns a negative number on buffer
2074 overflow, which isn't the case. Replaced with Exim's string_format()
2075 function.
2076 (b) There were several signed/unsigned issues. I just did the minimum
2077 hacking in of casts. There is scope for a larger refactoring.
2078 (c) The code used strcasecmp() which is not a standard C function.
2079 Replaced with Exim's strcmpic() function.
2080 (d) The code set only $1; it now sets $auth1 as well.
2081 (e) A simple test gave the error "authentication client didn't specify
2082 service in request". It would seem that Dovecot has changed its
2083 interface. Fortunately there's a specification; I followed it and
2084 changed what the client sends and it appears to be working now.

2089PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2090 address A is aliased to B and C, where B exists and C does not. Without
2091 -v the output is "A verified" because verification stops after a
2092 successful redirection if more than one address is generated. However,
2093 with -v the child addresses are also verified. Exim was outputting "A
2094 failed to verify" and then showing the successful verification for C,
2095 with its parentage. It now outputs "B failed to verify", showing B's
2096 parentage before showing the successful verification of C.

322050c2
PH
2102PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2103 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2104 they consult the DNS. I had assumed they would set it the way they
2105 wanted; and indeed my experiments on Linux seem to show that in some
2106 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2107 To be on the safe side, however, I have now made the interface to
2108 host_find_byname() similar to host_find_bydns(), with an argument
2109 containing the DNS resolver options. The host_find_byname() function now
2110 sets these options at its start, just as host_find_bydns() does. The smtp
2111 transport options dns_qualify_single and dns_search_parents are passed to
2112 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2113 of host_find_byname() use the default settings of RES_DEFNAMES
2114 (qualify_single) but not RES_DNSRCH (search_parents).

2116PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2117 spool_read_header() do less string testing, by means of a preliminary
2118 switch on the second character of optional "-foo" lines. (This is
2119 overdue, caused by the large number of possibilities that now exist.
2120 Originally there were few.) While I was there, I also converted the
2121 str(n)cmp tests so they don't re-test the leading "-" and the first
2122 character, in the hope this might squeeze out yet more improvement.

2124PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2125 flag allowing group syntax was set by the header_syntax check but not
2126 turned off, possible causing trouble later; (2) The flag was not being
2127 set at all for the header_verify test, causing "group"-style headers to
2128 be rejected. I have now set it in this case, and also caused header_
2129 verify to ignore an empty address taken from a group. While doing this, I
2130 came across some other cases where the code for allowing group syntax
2131 while scanning a header line wasn't quite right (mostly, not resetting
2132 the flag correctly in the right place). These bugs could have caused
2133 trouble for malformed header lines. I hope it is now all correct.

PH
2135PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2136 with the "reply" argument non-NULL. The code, however (which originally
2137 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2138 but it didn't always do it. This confused somebody who was copying the
2139 code for some other use. I have removed all the tests.

PH
2141PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2142 feature that was used to support insecure browsers during the U.S. crypto
2143 embargo. It requires special client support, and Exim is probably the
2144 only MTA that supported it -- and would never use it because real RSA is
2145 always available. This code has been removed, because it had the bad
2146 effect of slowing Exim down by computing (never used) parameters for the
2147 RSA_EXPORT functionality.

2149PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2150 authenticator to fail if there's a tab character in the incoming data

2152 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2153 if the connection is using TLS or if the remote IP is the same as the
2154 local IP, and the "valid-client-cert option" if a client certificate has
2155 been verified.

2186
2187PH/30 Exim was sometimes attempting to deliver messages that had suffered
2188 address errors (4xx response to RCPT) over the same connection as other
2189 messages routed to the same hosts. Such deliveries are always "forced",
2190 so retry times are not inspected. This resulted in far too many retries
2191 for the affected addresses. The effect occurred only when there were more
2192 hosts than the hosts_max_try setting in the smtp transport when it had
2193 the 4xx errors. Those hosts that it had tried were not added to the list
2194 of hosts for which the message was waiting, so if all were tried, there
2195 was no problem. Two fixes have been applied:
2196
2197 (i) If there are any address or message errors in an SMTP delivery, none
2198 of the hosts (tried or untried) are now added to the list of hosts
2199 for which the message is waiting, so the message should not be a
2200 candidate for sending over the same connection that was used for a
2201 successful delivery of some other message. This seems entirely
2202 reasonable: after all the message is NOT "waiting for some host".
2203 This is so "obvious" that I'm not sure why it wasn't done
2204 previously. Hope I haven't missed anything, but it can't do any
2205 harm, as the worst effect is to miss an optimization.
2206
2207 (ii) If, despite (i), such a delivery is accidentally attempted, the
2208 routing retry time is respected, so at least it doesn't keep
2209 hammering the server.

PH
2224PH/35 The error "getsockname() failed: connection reset by peer" was being
2225 written to the panic log as well as the main log, but it isn't really
2226 panic-worthy as it just means the connection died rather early on. I have
2227 removed the panic log writing for the ECONNRESET error when getsockname()
2228 fails.
2229
48c7f9e2
PH
2230PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2231 runs only) independently of the message's sender address. This meant
2232 that, if the 4xx error was in fact related to the sender, a different
2233 message to the same recipient with a different sender could confuse
2234 things. In particualar, this can happen when sending to a greylisting
2235 server, but other circumstances could also provoke similar problems.
2236 I have changed the default so that the retry time for these errors is now
2237 based a combination of the sender and recipient addresses. This change
2238 can be overridden by setting address_retry_include_sender=false in the
2239 smtp transport.

2510 tcp-wrappers gives "deny", whereas what one would like would be some
2511 kind of temporary error. A kludge has been added to help with this.
2512 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2513 554 error is used if errno is still zero or contains ENOENT (which occurs
2514 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2554 code found IPv4 interfaces correctly, but gave incorrect values for the
2555 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2556 that it would not match correctly against @[] and not recognize the IPv6
2557 addresses as local.

2600 autoreply, Exim could try to deliver to a non-existent relative file

2625 suitable debugging ouput when -d is set.

2635 additional section of a DNS packet that returns MX or SRV records.
2636 Instead, it always explicitly searches for A/AAAA records. This avoids
2637 major problems that occur when a DNS server includes only records of one
2638 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2639 fixed another bug: if SRV records were looked up and the corresponding
2640 address records were *not* found in the additional section, the port
2641 values from the SRV records were lost.

2643PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2651PH/19 When calculating a retry time, Exim used to measure the "time since
2652 failure" by looking at the "first failed" field in the retry record. Now
2653 it does not use this if it is later than than the arrival time of the
2654 message. Instead it uses the arrival time. This makes for better
2655 behaviour in cases where some deliveries succeed, thus re-setting the
2656 "first failed" field. An example is a quota failure for a huge message
2657 when small messages continue to be delivered. Without this change, the
2658 "time since failure" will always be short, possible causing more frequent
2659 delivery attempts for the huge message than are intended.

PH
2756PH/42 The content-scanning code uses fopen() to create files in which to put
2757 message data. Previously it was not paying any attention to the mode of
2758 the files. Exim runs with umask(0) because the rest of the code creates
2759 files with open(), and sets the required mode explicitly. Thus, these
2760 files were ending up world-writeable. This was not a big issue, because,
2761 being within the spool directory, they were not world-accessible. I have
2762 created a function called modefopen, which takes an additional mode
2763 argument. It sets umask(777), creates the file, chmods it to the required
2764 mode, then resets the umask. All the relevant calls to fopen() in the
2765 content scanning code have been changed to use this function.

2776 received. Setting client_ignore_invalid_base64 true ignores these errors.
2777 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2778 they are received. Thus, the responses can be made to depend on the

2800PH/52 Two bugs concerned with error handling when the smtp transport is
2801 used in LMTP mode:
2802
2803 (i) Exim was not creating retry information for temporary errors given
2804 for individual recipients after the DATA command when the smtp transport
2805 was used in LMTP mode. This meant that they could be retried too
2806 frequently, and not timed out correctly.
2807
2808 (ii) Exim was setting the flag that allows error details to be returned
2809 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2810 recipients that were returned after the DATA command.
2811
2812PH/53 This is related to PH/52, but is more general: for any failing address,
2813 when detailed error information was permitted to be returned to the
2814 sender, but the error was temporary, then after the final timeout, only
2815 "retry timeout exceeded" was returned. Now it returns the full error as

2886PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2887 function verify_get_ident() calls ip_connect() to connect a socket, but
2888 if the "connect()" function timed out, ip_connect() used to close the
2889 socket. However, verify_get_ident() also closes the socket later, and in
2890 between Exim writes to the log, which may get opened at this point. When
2891 the socket was closed in ip_connect(), the log could get the same file
2892 descriptor number as the socket. This naturally causes chaos. The fix is
2893 not to close the socket in ip_connect(); the socket should be closed by
2894 the function that creates it. There was only one place in the code where
2895 this was missing, in the iplookup router, which I don't think anybody now
2896 uses, but I've fixed it anyway.

2920 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2922
2923 (3) Reset the variables that are obtained from the first argument of
2924 ${prvscheck and used in the second argument before leaving the code,
2925 because their memory is reclaimed, so using them afterwards may do
2926 silly things.
2927
2928 (4) Tidy up the code for expanding the arguments of ${prvscheck one by

2953 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2954 not being looked up in the rDNS to get a host name, Exim was showing the
2955 IP address twice in Received: lines, even though the IP addresses were
2956 identical. For example:
2957
2958 Received: from [1.2.3.4] (helo=[1.2.3.4])
2959
2960 However, if the real host name was known, it was omitting the HELO data
2961 if it matched the actual IP address. This has been tidied up so that it
2962 doesn't show the same IP address twice.

2993 in the messages that it generates (bounce messages and others, such as
2994 warnings). In the case of bounce messages for non-SMTP mesages, there was
2995 also a typo: it was using "Auto_submitted" (underscore instead of
2996 hyphen). Since every message generated by Exim is necessarily in response
2997 to another message, thes have all been changed to:

3054 addresses acquired from the DNS when checking that the found name did
3055 have the original IP as one of its addresses. Since any found IPv6
3056 addresses are likely to be in abbreviated form, the comparison could
3057 fail. Luckily, there already exists a function for doing the comparison
3058 by converting both addresses to binary, so now that is used instead of
3059 the text comparison.

3138PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3139 run a filter in a subprocess. This could lead to confusion in subsequent

3141 the end of the subprocess.

3143PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3144 only if the host matched helo_try_verify_hosts, which caused the
3145 verification to occur when the EHLO/HELO command was issued. The ACL just
3146 tested the remembered result. Now, if a previous verification attempt has
3147 not happened, "verify = helo" does it there and then.

3176PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3177 authentication with radiusclient 0.4.9:
3178
3179 - Error returned from rc_read_config was caught wrongly
3180 - Username/password not passed on to radius server due to wrong length.
3181
3182 The presumption is that some radiusclient API changes for 4.51/PH/17
3183 were not taken care of correctly. The code is still untested by me (my
3184 Linux distribution still has 0.3.2 of radiusclient), but it was
3185 contributed by a Radius user.

3238 From: header, and the sender address was obtained from -f or from an SMTP
3239 MAIL command, and the trusted user did not use -F to supply a sender
3240 name, $originator_name was incorrectly used when constructing a From:
3241 header. Furthermore, $originator_name was used for submission mode
3242 messages from external hosts without From: headers in a similar way,
3243 which is clearly wrong.
