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.

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.

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.

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.

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}.

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

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-

183 delivery resulted in actual delivery. Cancel cutthrough before DATA
184 stage.

187 rejects a recipient: pass the reject to the originator.
188
dc8091e7
JH
189JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
190 Many were false-positives and ignorable, but it's worth fixing the
191 former class.

dfe7d917
JH
193JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
194 for the new environment-manipulation done at startup. Move the routines

208
01a4a5c5 209JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 210 is now done by default. The transport option tls_verify_cert_hostnames

dc7b3d36 251 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
252 modifiers per server. Patch originally by <rommer@active.by>.
253
254JH/16 The spamd_address main option now supports a mixed list of local

319Exim version 4.85
320-----------------
321TL/01 When running the test suite, the README says that variables such as
322 no_msglog_check are global and can be placed anywhere in a specific
323 test's script, however it was observed that placement needed to be near
324 the beginning for it to behave that way. Changed the runtest perl
325 script to read through the entire script once to detect and set these
326 variables, reset to the beginning of the script, and then run through
327 the script parsing/test process like normal.

354JH/05 Fix results-pipe from transport process. Several recipients, combined
355 with certificate use, exposed issues where response data items split
356 over buffer boundaries were not parsed properly. This eventually
357 resulted in duplicates being sent. This issue only became common enough
358 to notice due to the introduction of conection certificate information,
359 the item size being so much larger. Found and fixed by Wolfgang Breyha.

aec45841 371 and $event_defer_errno. There is a new variable $verify_mode, usable in

433 When a message was received over SMTP with TLS, Exim failed to clear up

435 deliver the message. In some situations the subsequent outgoing
436 delivery connection happened to have the same fd number as the incoming

684TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
685
686 When a queue runner is handling a message, Exim first routes the
687 recipient addresses, during which it prunes them based on the retry
688 hints database. After that it attempts to deliver the message to
689 any remaining recipients. It then updates the hints database using
690 the retry rules.
691
692 So if a recipient address works intermittently, it can get repeatedly
693 deferred at routing time. The retry hints record remains fresh so the
694 address never reaches the final cutoff time.
695
696 This is a fairly common occurrence when a user is bumping up against
697 their storage quota. Exim had some logic in its local delivery code
698 to deal with this. However it did not apply to per-recipient defers
699 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
700
1ddeb334
TF
701 This change adds a proper retry rule check during routing so that the
702 final cutoff time is checked against the message's age. We only do
703 this check if there is an address retry record and there is not a
704 domain retry record; this implies that previous attempts to handle
705 the address had the retry_use_local_parts option turned on. We use
706 this as an approximation for the destination being like a local
707 delivery, as in LMTP.
67bd1ab3
TF
708
709 I suspect this new check makes the old local delivery cutoff check
710 redundant, but I have not verified this so I left the code in place.

750 the body content is received and before the acl_smtp_data ACL.
751 The client is controlled by bolth of: a hosts_try_prdr option
752 on the smtp transport, and the server advertisement.
753 Default client logging of deliveries and rejections involving

1032TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1033 lock up or crash if it happened to be inside a call to libc when it
1034 got a SIGUSR1 from exiwhat.
1035
1036 The SIGUSR1 handler appends the current process status to the process
1037 log which is later printed by exiwhat. It used to use the general
1038 purpose logging code to do this, but several functions it calls are
1039 not safe for signals.
1040
1041 The new output code in the SIGUSR1 handler is specific to the process
1042 log, and simple enough that it's easy to inspect for signal safety.
1043 Removing some special cases also simplifies the general logging code.
1044 Removing the spurious timestamps from the process log simplifies
1045 exiwhat.

TF
1047TF/04 Improved ratelimit ACL condition.
1048
1049 The /noupdate option has been deprecated in favour of /readonly which
1050 has clearer semantics. The /leaky, /strict, and /readonly update modes
1051 are mutually exclusive. The update mode is no longer included in the
1052 database key; it just determines when the database is updated. (This
1053 means that when you upgrde Exim will forget old rate measurements.)
1054
1055 Exim now checks that the per_* options are used with an update mode that
1056 makes sense for the current ACL. For example, when Exim is processing a
1057 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1058 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1059 must specify per_mail/readonly. If you omit the update mode it defaults to
1060 /leaky where that makes sense (as before) or /readonly where required.
1061
1062 The /noupdate option is now undocumented but still supported for
1063 backwards compatibility. It is equivalent to /readonly except that in
1064 ACLs where /readonly is required you may specify /leaky/noupdate or
1065 /strict/noupdate which are treated the same as /readonly.
1066
1067 A useful new feature is the /count= option. This is a generalization
1068 of the per_byte option, so that you can measure the throughput of other
1069 aggregate values. For example, the per_byte option is now equivalent
1070 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1071
1072 The per_rcpt option has been generalized using the /count= mechanism
1073 (though it's more complicated than the per_byte equivalence). When it is
1074 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1075 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1076 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1077 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1078 Note that using per_rcpt with a non-readonly update mode in more than
1079 one ACL will cause the recipients to be double-counted. (The per_mail
1080 and per_byte options don't have this problem.)
1081
1082 The handling of very low rates has changed slightly. If the computed rate
1083 is less than the event's count (usually one) then this event is the first
1084 after a long gap. In this case the rate is set to the same as this event's
1085 count, so that the first message of a spam run is counted properly.
1086
1087 The major new feature is a mechanism for counting the rate of unique
1088 events. The new per_addr option counts the number of different
1089 recipients that someone has sent messages to in the last time period. It
1090 behaves like per_rcpt if all the recipient addresses are different, but
1091 duplicate recipient addresses do not increase the measured rate. Like
1092 the /count= option this is a general mechanism, so the per_addr option
1093 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1094 example, measure the rate that a client uses different sender addresses
1095 with the options per_mail/unique=$sender_address. There are further
1096 details in the main documentation.

1647 were called 'true' and it seems that C99 defines that as a reserved

1649 not include C99-style headers which use bools without triggering

1666-----------------
1667
1668PH/01 Another patch from the Sieve maintainer.
1669
6a3bceb1
PH
1670PH/02 When an IPv6 address is converted to a string for single-key lookup
1671 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1672 dots are used instead of colons so that keys in lsearch files need not
1673 contain colons. This was done some time before quoting was made available
1674 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1675 (notated using the quote facility) so as to distinguish them from IPv4
1676 keys. This meant that lookups for IP addresses in host lists did not work
1677 for iplsearch lookups.
1678
1679 This has been fixed by arranging for IPv6 addresses to be expressed with
1680 colons if the lookup type is iplsearch. This is not incompatible, because
1681 previously such lookups could never work.
1682
1683 The situation is now rather anomolous, since one *can* have colons in
1684 ordinary lsearch keys. However, making the change in all cases is
1685 incompatible and would probably break a number of configurations.

1690MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1691 conversion specification without a maximum field width, thereby enabling
1692 a rogue spamd server to cause a buffer overflow. While nobody in their
1693 right mind would setup Exim to query an untrusted spamd server, an
1694 attacker that gains access to a server running spamd could potentially
1695 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1700MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1701 a directory entry by the name of the lookup key. Previously, if a
1702 symlink pointed to a non-existing file or a file in a directory that
1703 Exim lacked permissions to read, a lookup for a key matching that
1704 symlink would fail. Now it is enough that a matching directory entry
1705 exists, symlink or not. (Bugzilla 503.)

1782 if a client was not listed at all, or was listed with a value other than

1888PH/29 SMTP synchronization checks are implemented when a command is read -
1889 there is a check that no more input is waiting when there shouldn't be
1890 any. However, for some commands, a delay in an ACL can mean that it is
1891 some time before the response is written. In this time, more input might
1892 arrive, invalidly. So now there are extra checks after an ACL has run for
1893 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1894 pipelining has not been advertised.

1909 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1910 was a macro that became an assignment, so it seemed to work. This has

1944 calls itself on a restart). I have changed the code so that it now always
1945 uses the Exim user.

1947PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1948 message are rejected with the same error (e.g. no authentication or bad
1949 sender address), and a DATA command is nevertheless sent (as can happen
1950 with PIPELINING or a stupid MUA), the error message that was given to the
1951 RCPT commands is included in the rejection of the DATA command. This is
1952 intended to be helpful for MUAs that show only the final error to their
1953 users.

PH
1968 the response to the final '.' that terminates a message, but only in the
1969 case where the client has not sent further data following the '.'
1970 (unfortunately, this is allowed). However, in many cases there won't be
1971 any further data because there won't be any more messages to send. A call
1972 to select() can be used: if it shows that the input is "ready", there is
1973 either input waiting, or the socket has been closed. An attempt to read
1974 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1975 would have sent an OK response which the client would never have see.

1983Exim version 4.66
1984-----------------
1985
1986PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1987 fixed by 4.65/MH/01 (is this a record?) are fixed:
1988
1989 (i) An empty string was always treated as zero by the numeric comparison
1990 operators. This behaviour has been restored.
1991
1992 (ii) It is documented that the numeric comparison operators always treat
1993 their arguments as decimal numbers. This was broken in that numbers
1994 starting with 0 were being interpreted as octal.
1995
1996 While fixing these problems I realized that there was another issue that
1997 hadn't been noticed. Values of message_size_limit (both the global option
1998 and the transport option) were treated as octal if they started with 0.
1999 The documentation was vague. These values are now always treated as
2000 decimal, and I will make that clear in the documentation.

2014PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

2016 is held in a short int, deliveries were likely to be lost. As such a
2017 large number of recipients for a single message is ridiculous
2018 (performance will be very, very poor), I have chosen to impose a limit
2019 rather than extend the field.

2025TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2026 leftover -K file (the existence of which was triggered by #402).

2034
2035TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

PH
2044PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2045 callout verification, Exim cached a "reject" for the entire domain. This
2046 is correct for most verifications, but it is not correct for a recipient
2047 verification with use_sender or use_postmaster set, because in that case
2048 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2049 case of MAIL FROM:<> rejection from other early rejections (e.g.
2050 rejection of HELO). When verifying a recipient using a non-null MAIL
2051 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2052 Whatever the result of the callout, the value of the domain cache is
2053 left unchanged (for any other kind of callout, getting as far as trying
2054 RCPT means that the domain itself is ok).

2088PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2090 probably the interface on which it is arriving) and not to the outgoing
2091 callout (which could be using a different interface). This has been
2092 changed to use the value of the helo_data option from the smtp transport
2093 instead - this is what is used when a message is actually being sent. If
2094 there is no remote transport (possible with a router that sets up host
2095 addresses), $smtp_active_hostname is used.

7befa435 2098 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2099 (a) The code assumed that strncpy() returns a negative number on buffer
2100 overflow, which isn't the case. Replaced with Exim's string_format()
2101 function.
2102 (b) There were several signed/unsigned issues. I just did the minimum
2103 hacking in of casts. There is scope for a larger refactoring.
2104 (c) The code used strcasecmp() which is not a standard C function.
2105 Replaced with Exim's strcmpic() function.
2106 (d) The code set only $1; it now sets $auth1 as well.
2107 (e) A simple test gave the error "authentication client didn't specify
2108 service in request". It would seem that Dovecot has changed its
2109 interface. Fortunately there's a specification; I followed it and
2110 changed what the client sends and it appears to be working now.

2115PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2116 address A is aliased to B and C, where B exists and C does not. Without
2117 -v the output is "A verified" because verification stops after a
2118 successful redirection if more than one address is generated. However,
2119 with -v the child addresses are also verified. Exim was outputting "A
2120 failed to verify" and then showing the successful verification for C,
2121 with its parentage. It now outputs "B failed to verify", showing B's
2122 parentage before showing the successful verification of C.

2127
322050c2
PH
2128PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2129 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2130 they consult the DNS. I had assumed they would set it the way they
2131 wanted; and indeed my experiments on Linux seem to show that in some
2132 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2133 To be on the safe side, however, I have now made the interface to
2134 host_find_byname() similar to host_find_bydns(), with an argument
2135 containing the DNS resolver options. The host_find_byname() function now
2136 sets these options at its start, just as host_find_bydns() does. The smtp
2137 transport options dns_qualify_single and dns_search_parents are passed to
2138 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2139 of host_find_byname() use the default settings of RES_DEFNAMES
2140 (qualify_single) but not RES_DNSRCH (search_parents).

2142PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2143 spool_read_header() do less string testing, by means of a preliminary
2144 switch on the second character of optional "-foo" lines. (This is
2145 overdue, caused by the large number of possibilities that now exist.
2146 Originally there were few.) While I was there, I also converted the
2147 str(n)cmp tests so they don't re-test the leading "-" and the first
2148 character, in the hope this might squeeze out yet more improvement.

2150PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2151 flag allowing group syntax was set by the header_syntax check but not
2152 turned off, possible causing trouble later; (2) The flag was not being
2153 set at all for the header_verify test, causing "group"-style headers to
2154 be rejected. I have now set it in this case, and also caused header_
2155 verify to ignore an empty address taken from a group. While doing this, I
2156 came across some other cases where the code for allowing group syntax
2157 while scanning a header line wasn't quite right (mostly, not resetting
2158 the flag correctly in the right place). These bugs could have caused
2159 trouble for malformed header lines. I hope it is now all correct.

PH
2161PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2162 with the "reply" argument non-NULL. The code, however (which originally
2163 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2164 but it didn't always do it. This confused somebody who was copying the
2165 code for some other use. I have removed all the tests.

PH
2167PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2168 feature that was used to support insecure browsers during the U.S. crypto
2169 embargo. It requires special client support, and Exim is probably the
2170 only MTA that supported it -- and would never use it because real RSA is
2171 always available. This code has been removed, because it had the bad
2172 effect of slowing Exim down by computing (never used) parameters for the
2173 RSA_EXPORT functionality.

PH
2175PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2176 authenticator to fail if there's a tab character in the incoming data
2177 (there should never be unless someone is messing about, as it's supposed
2178 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2179 if the connection is using TLS or if the remote IP is the same as the
2180 local IP, and the "valid-client-cert option" if a client certificate has
2181 been verified.

PH
2212
2213PH/30 Exim was sometimes attempting to deliver messages that had suffered
2214 address errors (4xx response to RCPT) over the same connection as other
2215 messages routed to the same hosts. Such deliveries are always "forced",
2216 so retry times are not inspected. This resulted in far too many retries
2217 for the affected addresses. The effect occurred only when there were more
2218 hosts than the hosts_max_try setting in the smtp transport when it had
2219 the 4xx errors. Those hosts that it had tried were not added to the list
2220 of hosts for which the message was waiting, so if all were tried, there
2221 was no problem. Two fixes have been applied:
2222
2223 (i) If there are any address or message errors in an SMTP delivery, none
2224 of the hosts (tried or untried) are now added to the list of hosts
2225 for which the message is waiting, so the message should not be a
2226 candidate for sending over the same connection that was used for a
2227 successful delivery of some other message. This seems entirely
2228 reasonable: after all the message is NOT "waiting for some host".
2229 This is so "obvious" that I'm not sure why it wasn't done
2230 previously. Hope I haven't missed anything, but it can't do any
2231 harm, as the worst effect is to miss an optimization.
2232
2233 (ii) If, despite (i), such a delivery is accidentally attempted, the
2234 routing retry time is respected, so at least it doesn't keep
2235 hammering the server.

PH
2250PH/35 The error "getsockname() failed: connection reset by peer" was being
2251 written to the panic log as well as the main log, but it isn't really
2252 panic-worthy as it just means the connection died rather early on. I have
2253 removed the panic log writing for the ECONNRESET error when getsockname()
2254 fails.
2255
48c7f9e2
PH
2256PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2257 runs only) independently of the message's sender address. This meant
2258 that, if the 4xx error was in fact related to the sender, a different
2259 message to the same recipient with a different sender could confuse
2260 things. In particualar, this can happen when sending to a greylisting
2261 server, but other circumstances could also provoke similar problems.
2262 I have changed the default so that the retry time for these errors is now
2263 based a combination of the sender and recipient addresses. This change
2264 can be overridden by setting address_retry_include_sender=false in the
2265 smtp transport.

2533PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2535 Unfortunately, if there is a major crisis, such as a disk failure,
2536 tcp-wrappers gives "deny", whereas what one would like would be some
2537 kind of temporary error. A kludge has been added to help with this.
2538 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2539 554 error is used if errno is still zero or contains ENOENT (which occurs
2540 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2541 451 error is used.

2577PH/01 The code for finding all the local interface addresses on a FreeBSD
2578 system running IPv6 was broken. This may well have applied to all BSD
2579 systems, as well as to others that have similar system calls. The broken
2580 code found IPv4 interfaces correctly, but gave incorrect values for the
2581 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2582 that it would not match correctly against @[] and not recognize the IPv6
2583 addresses as local.

2626 autoreply, Exim could try to deliver to a non-existent relative file
2627 name, causing unrelated and misleading errors. What now happens is that

2649 (a) Failures to set uid/gid, the current directory, or a process leader
2650 in a subprocess such as that created by queryprogram now generate
2651 suitable debugging ouput when -d is set.

2661 additional section of a DNS packet that returns MX or SRV records.
2662 Instead, it always explicitly searches for A/AAAA records. This avoids
2663 major problems that occur when a DNS server includes only records of one
2664 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2665 fixed another bug: if SRV records were looked up and the corresponding
2666 address records were *not* found in the additional section, the port
2667 values from the SRV records were lost.

2669PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2677PH/19 When calculating a retry time, Exim used to measure the "time since
2678 failure" by looking at the "first failed" field in the retry record. Now
2679 it does not use this if it is later than than the arrival time of the
2680 message. Instead it uses the arrival time. This makes for better
2681 behaviour in cases where some deliveries succeed, thus re-setting the
2682 "first failed" field. An example is a quota failure for a huge message
2683 when small messages continue to be delivered. Without this change, the
2684 "time since failure" will always be short, possible causing more frequent
2685 delivery attempts for the huge message than are intended.

PH
2782PH/42 The content-scanning code uses fopen() to create files in which to put
2783 message data. Previously it was not paying any attention to the mode of
2784 the files. Exim runs with umask(0) because the rest of the code creates
2785 files with open(), and sets the required mode explicitly. Thus, these
2786 files were ending up world-writeable. This was not a big issue, because,
2787 being within the spool directory, they were not world-accessible. I have
2788 created a function called modefopen, which takes an additional mode
2789 argument. It sets umask(777), creates the file, chmods it to the required
2790 mode, then resets the umask. All the relevant calls to fopen() in the
2791 content scanning code have been changed to use this function.

2802 received. Setting client_ignore_invalid_base64 true ignores these errors.
2803 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2804 they are received. Thus, the responses can be made to depend on the

2826PH/52 Two bugs concerned with error handling when the smtp transport is
2827 used in LMTP mode:
2828
2829 (i) Exim was not creating retry information for temporary errors given
2830 for individual recipients after the DATA command when the smtp transport
2831 was used in LMTP mode. This meant that they could be retried too
2832 frequently, and not timed out correctly.
2833
2834 (ii) Exim was setting the flag that allows error details to be returned
2835 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2836 recipients that were returned after the DATA command.
2837
2838PH/53 This is related to PH/52, but is more general: for any failing address,
2839 when detailed error information was permitted to be returned to the
2840 sender, but the error was temporary, then after the final timeout, only
2841 "retry timeout exceeded" was returned. Now it returns the full error as

2912PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2913 function verify_get_ident() calls ip_connect() to connect a socket, but
2914 if the "connect()" function timed out, ip_connect() used to close the
2915 socket. However, verify_get_ident() also closes the socket later, and in
2916 between Exim writes to the log, which may get opened at this point. When
2917 the socket was closed in ip_connect(), the log could get the same file
2918 descriptor number as the socket. This naturally causes chaos. The fix is
2919 not to close the socket in ip_connect(); the socket should be closed by
2920 the function that creates it. There was only one place in the code where
2921 this was missing, in the iplookup router, which I don't think anybody now
2922 uses, but I've fixed it anyway.

2946 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2948
2949 (3) Reset the variables that are obtained from the first argument of
2950 ${prvscheck and used in the second argument before leaving the code,
2951 because their memory is reclaimed, so using them afterwards may do
2952 silly things.
2953
2954 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2955 one (it's much easier than Tom thought :-).

2979 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2980 not being looked up in the rDNS to get a host name, Exim was showing the
2981 IP address twice in Received: lines, even though the IP addresses were
2982 identical. For example:
2983
2984 Received: from [1.2.3.4] (helo=[1.2.3.4])
2985
2986 However, if the real host name was known, it was omitting the HELO data

2988 doesn't show the same IP address twice.

3080 addresses acquired from the DNS when checking that the found name did
3081 have the original IP as one of its addresses. Since any found IPv6
3082 addresses are likely to be in abbreviated form, the comparison could
3083 fail. Luckily, there already exists a function for doing the comparison
3084 by converting both addresses to binary, so now that is used instead of
3085 the text comparison.

3132PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of

3164PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to

3167 the end of the subprocess.

3169PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3170 only if the host matched helo_try_verify_hosts, which caused the
3171 verification to occur when the EHLO/HELO command was issued. The ACL just
3172 tested the remembered result. Now, if a previous verification attempt has
3173 not happened, "verify = helo" does it there and then.

PH
3202PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3203 authentication with radiusclient 0.4.9:
3204
3205 - Error returned from rc_read_config was caught wrongly
3206 - Username/password not passed on to radius server due to wrong length.
3207
3208 The presumption is that some radiusclient API changes for 4.51/PH/17
3209 were not taken care of correctly. The code is still untested by me (my
3210 Linux distribution still has 0.3.2 of radiusclient), but it was
3211 contributed by a Radius user.

3226PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3229 header lines when this was not necessary.

3263PH/36 When a locally submitted message by a trusted user did not contain a
3264 From: header, and the sender address was obtained from -f or from an SMTP
3265 MAIL command, and the trusted user did not use -F to supply a sender
3266 name, $originator_name was incorrectly used when constructing a From:
3267 header. Furthermore, $originator_name was used for submission mode
3268 messages from external hosts without From: headers in a similar way,
3269 which is clearly wrong.
