6JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
7 supports it and a size is available (ie. the sending peer gave us one).

03d5892b
JH
9JH/02 The obsolete acl condition "demime" is removed (finally, after ten
10 years of being deprecated). The replacements are the ACLs
11 acl_smtp_mime and acl_not_smtp_mime.
12
4b0fe319
JH
13JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
14 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
15 or even an in-clear connection were permitted. Now, if the host lookup
16 was dnssec and dane was requested then the host is only used if the
17 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
18 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
19 if one fails this test.
20 This means that a poorly-configured remote DNS will make it incommunicado;
21 but it protects against a DNS-interception attack on it.

37-----------------
82d14d6a
JH
38JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
39 and 3.4.4 - once the server is enabled to respond to an OCSP request
40 it does even when not requested, resulting in a stapling non-aware
41 client dropping the TLS connection.

43TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
44 support variable-length bit vectors. No functional change.
45
ac881e27
TF
46TF/02 Improve the consistency of logging incoming and outgoing interfaces.
47 The I= interface field on outgoing lines is now after the H= remote
48 host field, same as incoming lines. There is a separate
49 outgoing_interface log selector which allows you to disable the
50 outgoing I= field.
51
c8899c20
JH
52JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
53 If not running log_selector +smtp_connection the mainlog would be held
54 open indefinitely after a "too many connections" event, including to a
55 deleted file after a log rotate. Leave the per net connection logging
56 leaving it open for efficiency as that will be quickly detected by the
57 check on the next write.

59HS/01 Bug 1671: Fix post transport crash.
60 Processing the wait-<transport> messages could crash the delivery
61 process if the message IDs didn't exist for some reason. When
62 using 'split_spool_directory=yes' the construction of the spool
63 file name failed already, exposing the same netto behaviour.

68JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
69 to DSN fail messages (bounces): remote IP, remote greeting, remote response
70 to HELO, local diagnostic string.
71
805bb5c3
JH
72JH/05 Downgrade message for a TLS-certificate-based authentication fail from
73 log line to debug. Even when configured with a tls authenticator many
74 client connections are expected to not authenticate in this way, so
75 an authenticate fail is not an error.

77HS/02 Add the Exim version string to the process info. This way exiwhat
78 gives some more detail about the running daemon.

80JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
81 matter for fast-change records such as DNSBLs.
82
6f6dedcc
JH
83JH/07 Bug 1678: Always record an interface option value, if set, as part of a
84 retry record, even if constant. There may be multiple transports with
85 different interface settings and the retry behaviour needs to be kept
86 distinct.

95 hosts_randomize. This matters a lot when combined with mua_wrapper.

103 with Radius support; from the Gentoo tree and checked under Fedora.

110JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
111
23f3dc67
JH
112JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
113 defaults to "*" (all hosts). The variable is now available when not built
114 with TLS, default unset, mainly to enable keeping the testuite sane.
115 If a server certificate is not supplied (via tls_certificate) an error is
116 logged, and clients will find TLS connections fail on startup. Presumably
117 they will retry in-clear.
118 Packagers of Exim are strongly encouraged to create a server certificate
119 at installation time.
120
240c288f
JH
121HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
122 with the $config_file variable.
123
5ef5dd52
JB
124JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
125 in transport context, after the attempt, and per-recipient. The latter type
126 is per host attempted. The event data is the error message, and the errno
127 information encodes the lookup type (A vs. MX) used for the (first) host,
128 and the trailing two digits of the smtp 4xx reponse.
129

GF
130GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
131 to write to mainlog (or rejectlog, paniclog) in the window between file
132 creation and permissions/ownership being changed. Particularly affects
133 installations where exicyclog is run as root, rather than exim user;
134 result is that the running daemon panics and dies.

139 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
140 "pri" and "weight". Note that the previous implicit priority given by the
141 list order is no longer honoured.

150 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989

f444c2c7
JH
174JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
175 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
176 only supported when built with TLS support. The PolarSSL SHA routines
177 are still used when the TLS library is too old for convenient support.
f444c2c7 178
a57b6200
JH
179JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
180 openssl_options), for security. OpenSSL forces this from version 1.1.0
181 server-side so match that on older versions.
182
07c73177 183JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 184 allocation for $value could be released as the expansion processing
07c73177 185 concluded, but leaving the global pointer active for it.

187JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
188 and to use the domains and local_parts ACL conditions.
189
1bc460a6
JH
190JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
191 incorrectly not doubled on cutthrough transmission, hence seen as a
192 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 193 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
194 via the normal store-and-forward channel. This could result in duplicates
195 received - but deduplicating mailstores were liable to retain only the
196 initial truncated version.

231 extraction. Accept either.

01a4a5c5 245JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 246 is now done by default. The transport option tls_verify_cert_hostnames

256 default, for both outbound TLS and client-certificate supplying inbound
257 TLS connections

262JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
263 Status Notification (bounce) messages are now MIME format per RFC 3464.
264 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised
265 under the control of the dsn_advertise_hosts option, and routers may
266 have a dsn_lasthop option.

357Exim version 4.85
358-----------------
359TL/01 When running the test suite, the README says that variables such as
360 no_msglog_check are global and can be placed anywhere in a specific
361 test's script, however it was observed that placement needed to be near
362 the beginning for it to behave that way. Changed the runtest perl
363 script to read through the entire script once to detect and set these
364 variables, reset to the beginning of the script, and then run through
365 the script parsing/test process like normal.

392JH/05 Fix results-pipe from transport process. Several recipients, combined
393 with certificate use, exposed issues where response data items split
394 over buffer boundaries were not parsed properly. This eventually
395 resulted in duplicates being sent. This issue only became common enough
396 to notice due to the introduction of conection certificate information,
397 the item size being so much larger. Found and fixed by Wolfgang Breyha.

722TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
723
724 When a queue runner is handling a message, Exim first routes the
725 recipient addresses, during which it prunes them based on the retry
726 hints database. After that it attempts to deliver the message to
727 any remaining recipients. It then updates the hints database using
728 the retry rules.
729
730 So if a recipient address works intermittently, it can get repeatedly
731 deferred at routing time. The retry hints record remains fresh so the
732 address never reaches the final cutoff time.
733
734 This is a fairly common occurrence when a user is bumping up against
735 their storage quota. Exim had some logic in its local delivery code
736 to deal with this. However it did not apply to per-recipient defers
737 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
738
1ddeb334
TF
739 This change adds a proper retry rule check during routing so that the
740 final cutoff time is checked against the message's age. We only do
741 this check if there is an address retry record and there is not a
742 domain retry record; this implies that previous attempts to handle
743 the address had the retry_use_local_parts option turned on. We use
744 this as an approximation for the destination being like a local
745 delivery, as in LMTP.
67bd1ab3
TF
746
747 I suspect this new check makes the old local delivery cutoff check
748 redundant, but I have not verified this so I left the code in place.

1070TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1071 lock up or crash if it happened to be inside a call to libc when it
1072 got a SIGUSR1 from exiwhat.
1073
1074 The SIGUSR1 handler appends the current process status to the process
1075 log which is later printed by exiwhat. It used to use the general
1076 purpose logging code to do this, but several functions it calls are
1077 not safe for signals.
1078
1079 The new output code in the SIGUSR1 handler is specific to the process
1080 log, and simple enough that it's easy to inspect for signal safety.
1081 Removing some special cases also simplifies the general logging code.
1082 Removing the spurious timestamps from the process log simplifies
1083 exiwhat.
1084
c99ce5c9
TF
1085TF/04 Improved ratelimit ACL condition.
1086
1087 The /noupdate option has been deprecated in favour of /readonly which
1088 has clearer semantics. The /leaky, /strict, and /readonly update modes
1089 are mutually exclusive. The update mode is no longer included in the
1090 database key; it just determines when the database is updated. (This
1091 means that when you upgrde Exim will forget old rate measurements.)
1092
1093 Exim now checks that the per_* options are used with an update mode that
1094 makes sense for the current ACL. For example, when Exim is processing a
1095 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1096 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1097 must specify per_mail/readonly. If you omit the update mode it defaults to
1098 /leaky where that makes sense (as before) or /readonly where required.
1099
1100 The /noupdate option is now undocumented but still supported for
1101 backwards compatibility. It is equivalent to /readonly except that in
1102 ACLs where /readonly is required you may specify /leaky/noupdate or
1103 /strict/noupdate which are treated the same as /readonly.
1104
1105 A useful new feature is the /count= option. This is a generalization
1106 of the per_byte option, so that you can measure the throughput of other
1107 aggregate values. For example, the per_byte option is now equivalent
1108 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1109
1110 The per_rcpt option has been generalized using the /count= mechanism
1111 (though it's more complicated than the per_byte equivalence). When it is
1112 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1113 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1114 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1115 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1116 Note that using per_rcpt with a non-readonly update mode in more than
1117 one ACL will cause the recipients to be double-counted. (The per_mail
1118 and per_byte options don't have this problem.)
1119
1120 The handling of very low rates has changed slightly. If the computed rate
1121 is less than the event's count (usually one) then this event is the first
1122 after a long gap. In this case the rate is set to the same as this event's
1123 count, so that the first message of a spam run is counted properly.
1124
1125 The major new feature is a mechanism for counting the rate of unique
1126 events. The new per_addr option counts the number of different
1127 recipients that someone has sent messages to in the last time period. It
1128 behaves like per_rcpt if all the recipient addresses are different, but
1129 duplicate recipient addresses do not increase the measured rate. Like
1130 the /count= option this is a general mechanism, so the per_addr option
1131 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1132 example, measure the rate that a client uses different sender addresses
1133 with the options per_mail/unique=$sender_address. There are further
1134 details in the main documentation.

1685 were called 'true' and it seems that C99 defines that as a reserved

1706PH/01 Another patch from the Sieve maintainer.
1707
6a3bceb1
PH
1708PH/02 When an IPv6 address is converted to a string for single-key lookup
1709 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1710 dots are used instead of colons so that keys in lsearch files need not
1711 contain colons. This was done some time before quoting was made available
1712 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1713 (notated using the quote facility) so as to distinguish them from IPv4
1714 keys. This meant that lookups for IP addresses in host lists did not work
1715 for iplsearch lookups.
1716
1717 This has been fixed by arranging for IPv6 addresses to be expressed with
1718 colons if the lookup type is iplsearch. This is not incompatible, because
1719 previously such lookups could never work.
1720
1721 The situation is now rather anomolous, since one *can* have colons in
1722 ordinary lsearch keys. However, making the change in all cases is
1723 incompatible and would probably break a number of configurations.

MH
1728MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1729 conversion specification without a maximum field width, thereby enabling
1730 a rogue spamd server to cause a buffer overflow. While nobody in their
1731 right mind would setup Exim to query an untrusted spamd server, an
1732 attacker that gains access to a server running spamd could potentially
1733 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1738MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1739 a directory entry by the name of the lookup key. Previously, if a
1740 symlink pointed to a non-existing file or a file in a directory that
1741 Exim lacked permissions to read, a lookup for a key matching that
1742 symlink would fail. Now it is enough that a matching directory entry
1743 exists, symlink or not. (Bugzilla 503.)

1927 there is a check that no more input is waiting when there shouldn't be

1929 some time before the response is written. In this time, more input might
1930 arrive, invalidly. So now there are extra checks after an ACL has run for
1931 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1932 pipelining has not been advertised.

1945 Exim which did not show up earlier: it was assuming that a call to
1946 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1947 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1948 was a macro that became an assignment, so it seemed to work. This has
1949 changed to a proper function call with a void return, hence the compile
1950 error. Exim's code has been fixed.

2006 the response to the final '.' that terminates a message, but only in the
2007 case where the client has not sent further data following the '.'
2008 (unfortunately, this is allowed). However, in many cases there won't be
2009 any further data because there won't be any more messages to send. A call
2010 to select() can be used: if it shows that the input is "ready", there is
2011 either input waiting, or the socket has been closed. An attempt to read
2012 the next input character can distinguish the two cases. Previously, Exim

2023
2024PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2025 fixed by 4.65/MH/01 (is this a record?) are fixed:
2026
2027 (i) An empty string was always treated as zero by the numeric comparison
2028 operators. This behaviour has been restored.
2029
2030 (ii) It is documented that the numeric comparison operators always treat
2031 their arguments as decimal numbers. This was broken in that numbers
2032 starting with 0 were being interpreted as octal.
2033
2034 While fixing these problems I realized that there was another issue that
2035 hadn't been noticed. Values of message_size_limit (both the global option
2036 and the transport option) were treated as octal if they started with 0.
2037 The documentation was vague. These values are now always treated as
2038 decimal, and I will make that clear in the documentation.

2054 is held in a short int, deliveries were likely to be lost. As such a
2055 large number of recipients for a single message is ridiculous
2056 (performance will be very, very poor), I have chosen to impose a limit
2057 rather than extend the field.

PH
2082PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2083 callout verification, Exim cached a "reject" for the entire domain. This
2084 is correct for most verifications, but it is not correct for a recipient
2085 verification with use_sender or use_postmaster set, because in that case
2086 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2087 case of MAIL FROM:<> rejection from other early rejections (e.g.
2088 rejection of HELO). When verifying a recipient using a non-null MAIL
2089 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2090 Whatever the result of the callout, the value of the domain cache is
2091 left unchanged (for any other kind of callout, getting as far as trying
2092 RCPT means that the domain itself is ok).

2126PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2128 probably the interface on which it is arriving) and not to the outgoing
2129 callout (which could be using a different interface). This has been
2130 changed to use the value of the helo_data option from the smtp transport
2131 instead - this is what is used when a message is actually being sent. If
2132 there is no remote transport (possible with a router that sets up host
2133 addresses), $smtp_active_hostname is used.

14aa5a05
PH
2137 (a) The code assumed that strncpy() returns a negative number on buffer
2138 overflow, which isn't the case. Replaced with Exim's string_format()
2139 function.
2140 (b) There were several signed/unsigned issues. I just did the minimum
2141 hacking in of casts. There is scope for a larger refactoring.
2142 (c) The code used strcasecmp() which is not a standard C function.
2143 Replaced with Exim's strcmpic() function.
2144 (d) The code set only $1; it now sets $auth1 as well.
2145 (e) A simple test gave the error "authentication client didn't specify
2146 service in request". It would seem that Dovecot has changed its
2147 interface. Fortunately there's a specification; I followed it and
2148 changed what the client sends and it appears to be working now.

2154 address A is aliased to B and C, where B exists and C does not. Without
2155 -v the output is "A verified" because verification stops after a
2156 successful redirection if more than one address is generated. However,
2157 with -v the child addresses are also verified. Exim was outputting "A
2158 failed to verify" and then showing the successful verification for C,
2159 with its parentage. It now outputs "B failed to verify", showing B's
2160 parentage before showing the successful verification of C.

PH
2166PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2167 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2168 they consult the DNS. I had assumed they would set it the way they
2169 wanted; and indeed my experiments on Linux seem to show that in some
2170 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2171 To be on the safe side, however, I have now made the interface to
2172 host_find_byname() similar to host_find_bydns(), with an argument
2173 containing the DNS resolver options. The host_find_byname() function now
2174 sets these options at its start, just as host_find_bydns() does. The smtp
2175 transport options dns_qualify_single and dns_search_parents are passed to
2176 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2177 of host_find_byname() use the default settings of RES_DEFNAMES
2178 (qualify_single) but not RES_DNSRCH (search_parents).

2180PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2181 spool_read_header() do less string testing, by means of a preliminary
2182 switch on the second character of optional "-foo" lines. (This is
2183 overdue, caused by the large number of possibilities that now exist.
2184 Originally there were few.) While I was there, I also converted the
2185 str(n)cmp tests so they don't re-test the leading "-" and the first
2186 character, in the hope this might squeeze out yet more improvement.

2188PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2189 flag allowing group syntax was set by the header_syntax check but not
2190 turned off, possible causing trouble later; (2) The flag was not being
2191 set at all for the header_verify test, causing "group"-style headers to
2192 be rejected. I have now set it in this case, and also caused header_
2193 verify to ignore an empty address taken from a group. While doing this, I
2194 came across some other cases where the code for allowing group syntax
2195 while scanning a header line wasn't quite right (mostly, not resetting
2196 the flag correctly in the right place). These bugs could have caused
2197 trouble for malformed header lines. I hope it is now all correct.

PH
2199PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2201 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2202 but it didn't always do it. This confused somebody who was copying the
2203 code for some other use. I have removed all the tests.

PH
2205PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2206 feature that was used to support insecure browsers during the U.S. crypto
2207 embargo. It requires special client support, and Exim is probably the
2208 only MTA that supported it -- and would never use it because real RSA is
2209 always available. This code has been removed, because it had the bad
2210 effect of slowing Exim down by computing (never used) parameters for the
2211 RSA_EXPORT functionality.

2216 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2217 if the connection is using TLS or if the remote IP is the same as the
2218 local IP, and the "valid-client-cert option" if a client certificate has

PH
2250
2251PH/30 Exim was sometimes attempting to deliver messages that had suffered
2252 address errors (4xx response to RCPT) over the same connection as other
2253 messages routed to the same hosts. Such deliveries are always "forced",
2254 so retry times are not inspected. This resulted in far too many retries
2255 for the affected addresses. The effect occurred only when there were more
2256 hosts than the hosts_max_try setting in the smtp transport when it had
2257 the 4xx errors. Those hosts that it had tried were not added to the list
2258 of hosts for which the message was waiting, so if all were tried, there
2259 was no problem. Two fixes have been applied:
2260
2261 (i) If there are any address or message errors in an SMTP delivery, none
2262 of the hosts (tried or untried) are now added to the list of hosts
2263 for which the message is waiting, so the message should not be a
2264 candidate for sending over the same connection that was used for a
2265 successful delivery of some other message. This seems entirely
2266 reasonable: after all the message is NOT "waiting for some host".
2267 This is so "obvious" that I'm not sure why it wasn't done
2268 previously. Hope I haven't missed anything, but it can't do any
2269 harm, as the worst effect is to miss an optimization.
2270
2271 (ii) If, despite (i), such a delivery is accidentally attempted, the
2272 routing retry time is respected, so at least it doesn't keep
2273 hammering the server.

2288PH/35 The error "getsockname() failed: connection reset by peer" was being
2289 written to the panic log as well as the main log, but it isn't really

2291 removed the panic log writing for the ECONNRESET error when getsockname()
2292 fails.
2293
48c7f9e2
PH
2294PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2295 runs only) independently of the message's sender address. This meant
2296 that, if the 4xx error was in fact related to the sender, a different
2297 message to the same recipient with a different sender could confuse
2298 things. In particualar, this can happen when sending to a greylisting
2299 server, but other circumstances could also provoke similar problems.
2300 I have changed the default so that the retry time for these errors is now
2301 based a combination of the sender and recipient addresses. This change
2302 can be overridden by setting address_retry_include_sender=false in the
2303 smtp transport.

2571PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2573 Unfortunately, if there is a major crisis, such as a disk failure,
2574 tcp-wrappers gives "deny", whereas what one would like would be some
2575 kind of temporary error. A kludge has been added to help with this.
2576 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2577 554 error is used if errno is still zero or contains ENOENT (which occurs
2578 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2579 451 error is used.

2619 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2664 autoreply, Exim could try to deliver to a non-existent relative file

2700 Instead, it always explicitly searches for A/AAAA records. This avoids
2701 major problems that occur when a DNS server includes only records of one
2702 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2703 fixed another bug: if SRV records were looked up and the corresponding
2704 address records were *not* found in the additional section, the port
2705 values from the SRV records were lost.

PH
2715PH/19 When calculating a retry time, Exim used to measure the "time since
2716 failure" by looking at the "first failed" field in the retry record. Now
2717 it does not use this if it is later than than the arrival time of the
2718 message. Instead it uses the arrival time. This makes for better
2719 behaviour in cases where some deliveries succeed, thus re-setting the
2720 "first failed" field. An example is a quota failure for a huge message

PH
2820PH/42 The content-scanning code uses fopen() to create files in which to put
2821 message data. Previously it was not paying any attention to the mode of
2822 the files. Exim runs with umask(0) because the rest of the code creates
2823 files with open(), and sets the required mode explicitly. Thus, these
2824 files were ending up world-writeable. This was not a big issue, because,
2825 being within the spool directory, they were not world-accessible. I have
2826 created a function called modefopen, which takes an additional mode
2827 argument. It sets umask(777), creates the file, chmods it to the required
2828 mode, then resets the umask. All the relevant calls to fopen() in the
2829 content scanning code have been changed to use this function.

2840 received. Setting client_ignore_invalid_base64 true ignores these errors.
2841 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2842 they are received. Thus, the responses can be made to depend on the

2864PH/52 Two bugs concerned with error handling when the smtp transport is
2865 used in LMTP mode:
2866
2867 (i) Exim was not creating retry information for temporary errors given
2868 for individual recipients after the DATA command when the smtp transport
2869 was used in LMTP mode. This meant that they could be retried too
2870 frequently, and not timed out correctly.
2871
2872 (ii) Exim was setting the flag that allows error details to be returned
2873 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2874 recipients that were returned after the DATA command.
2875
2876PH/53 This is related to PH/52, but is more general: for any failing address,
2877 when detailed error information was permitted to be returned to the
2878 sender, but the error was temporary, then after the final timeout, only
2879 "retry timeout exceeded" was returned. Now it returns the full error as
2880 well as "retry timeout exceeded".

2950PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2951 function verify_get_ident() calls ip_connect() to connect a socket, but
2952 if the "connect()" function timed out, ip_connect() used to close the
2953 socket. However, verify_get_ident() also closes the socket later, and in
2954 between Exim writes to the log, which may get opened at this point. When
2955 the socket was closed in ip_connect(), the log could get the same file
2956 descriptor number as the socket. This naturally causes chaos. The fix is
2957 not to close the socket in ip_connect(); the socket should be closed by
2958 the function that creates it. There was only one place in the code where
2959 this was missing, in the iplookup router, which I don't think anybody now
2960 uses, but I've fixed it anyway.

2987 (3) Reset the variables that are obtained from the first argument of
2988 ${prvscheck and used in the second argument before leaving the code,
2989 because their memory is reclaimed, so using them afterwards may do
2990 silly things.

3017 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3018 not being looked up in the rDNS to get a host name, Exim was showing the
3019 IP address twice in Received: lines, even though the IP addresses were
3020 identical. For example:
3021
3022 Received: from [1.2.3.4] (helo=[1.2.3.4])
3023
3024 However, if the real host name was known, it was omitting the HELO data

3026 doesn't show the same IP address twice.

3118 addresses acquired from the DNS when checking that the found name did

3120 addresses are likely to be in abbreviated form, the comparison could

3127 form, whereas the current host's name might or might not be abbreviated.
3128 The same fix has been applied.

3143PH/04 Tighten up "personal" tests: Instead of testing for any "List-"
3144 header line, restrict the check to what is listed in RFCs 2369 and 2929.
3145 Also, for "Auto-Submitted", treat anything other than "no" as
3146 non-personal, in accordance with RFC 3834. (Previously it treated
3147 anything starting "auto-" as non-personal.)

3149TF/01 The control=submission/name=... option had a problem with syntax
3150 errors if the name included a slash character. The /name= option
3151 now slurps the rest of the string, so it can include any characters
3152 but it must come last in the list of options (after /sender_retain
3153 or /domain=).

PH
3170PH/03 When creating an mbox file for a virus/spam scan, use fseek() instead of
3171 fread() to skip over the body file's header line, because in Cygwin the
3172 header line is locked and is inaccessible.

PH
3174PH/04 Added $message_exim_id, ultimately to replace $message_id (they will both
3175 co-exist for some time) to make it clear that it is the Exim ID that is
3176 referenced, not the Message-ID: header line.

3202PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to
3203 run a filter in a subprocess. This could lead to confusion in subsequent
3204 lookups in the parent process. There should also be a search_tidyup() at
3205 the end of the subprocess.

PH
3207PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3208 only if the host matched helo_try_verify_hosts, which caused the
3209 verification to occur when the EHLO/HELO command was issued. The ACL just
3210 tested the remembered result. Now, if a previous verification attempt has
3211 not happened, "verify = helo" does it there and then.

3230PH/20 If a delivery was routed to a non-standard port by means of an SRV

3240PH/23 Applied a patch to fix problems with exim-4.52 while doing radius
3241 authentication with radiusclient 0.4.9:
3242
3243 - Error returned from rc_read_config was caught wrongly
3244 - Username/password not passed on to radius server due to wrong length.
3245
3246 The presumption is that some radiusclient API changes for 4.51/PH/17
3247 were not taken care of correctly. The code is still untested by me (my
3248 Linux distribution still has 0.3.2 of radiusclient), but it was
3249 contributed by a Radius user.

3264PH/26 Exim was recognizing IPv6 addresses of the form [IPv6:....] in EHLO

3267 header lines when this was not necessary.

3271PH/28 Exim tries to create and chdir to its spool directory when it starts;

3301PH/36 When a locally submitted message by a trusted user did not contain a
3302 From: header, and the sender address was obtained from -f or from an SMTP
3303 MAIL command, and the trusted user did not use -F to supply a sender
3304 name, $originator_name was incorrectly used when constructing a From:
3305 header. Furthermore, $originator_name was used for submission mode
3306 messages from external hosts without From: headers in a similar way,
3307 which is clearly wrong.
