4Exim version 4.88

JH
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).
8d042305 8
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.

23JH/04 Bug 1810: make continued-use of an open smtp transport connection
24 non-noisy when a race steals the message being considered.

JH
26JH/05 If main configuration option tls_certificate is unset, generate a
27 selfsigned certificate for inbound TLS connections.
28
0bd1b1ed 29JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 30 in rewrites and routers.
0bd1b1ed 31
20b9a2dc
JH
32JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
33 and logged a warning sing 4.83; now they are a configuration file error.
34
05392bbc
JH
35JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
36 (lacking @domain). Apply the same qualification processing as RCPT.
37
1a6230a3
JH
38JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
39
cfab9d68
JH
40JH/10 Support ${sha256:} applied to a string (as well as the previous
41 certificate).
42
98c82a3d
JH
43JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
44 a cutthrough deliver is pending, as we always want to make a connection.
45 This also avoids re-routing the message when later placing the cutthrough
46 connection after a verify cache hit.
47 Do not update it with the verify result either.
48
49JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
50 when routing results in more than one destination address.
51
ae8386f0
JH
52JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
53 signing (which inhibits the cutthrough capability). Previously only
54 the presence of an option was tested; now an expansion evaluating as
55 empty is permissible (obviously it should depend only on data available
56 when the cutthrough connection is made).
57
0d9fa8c0
JH
58JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
59 the relevant preceding SMTP command did not note the pipelining mode.
60
3581f321
JH
61JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
62 Previously they were not counted.
63
ef3a1a30
JH
64JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
65 as one having no matching records. Previously we deferred the message
66 that needed the lookup.
67
803628d5 68JH/17 Fakereject: previously logged as a norml message arrival "<="; now

70

JH
71JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
72 for missing MX records. Previously it only worked for missing A records.

JB
74JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
75
76JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
77 after the data-go-ahead and data-ack. Patch from Jason Betts.

79JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
80 even for a "none" policy. Patch from Tony Meyer.
81
1c788856
JH
82JH/22 Fix continued use of a connection for further deliveries. If a port was
83 specified by a router, it must also match for the delivery to be
84 compatible.
85
e3b1f624
JH
86JH/23 Bug 1874: fix continued use of a connection for further deliveries.
87 When one of the recipients of a message was unsuitable for the connection
88 (has no matching addresses), we lost track of needing to mark it
89 deferred. As a result mail would be lost.

JH
91JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
92
d7bed771 93JH/25 Decoding ACL controls is now done using a binary search; the sourcecode
2d009132
JH
94 takes up less space and should be simpler to maintain. Merge the ACL
95 condition decode tables also, with similar effect.

JH
100JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
101 and 3.4.4 - once the server is enabled to respond to an OCSP request
102 it does even when not requested, resulting in a stapling non-aware
103 client dropping the TLS connection.

TF
105TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
106 support variable-length bit vectors. No functional change.
107
ac881e27
TF
108TF/02 Improve the consistency of logging incoming and outgoing interfaces.
109 The I= interface field on outgoing lines is now after the H= remote
110 host field, same as incoming lines. There is a separate
111 outgoing_interface log selector which allows you to disable the
112 outgoing I= field.
113
c8899c20
JH
114JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
115 If not running log_selector +smtp_connection the mainlog would be held
116 open indefinitely after a "too many connections" event, including to a
117 deleted file after a log rotate. Leave the per net connection logging
118 leaving it open for efficiency as that will be quickly detected by the
119 check on the next write.

HSHR
121HS/01 Bug 1671: Fix post transport crash.
122 Processing the wait-<transport> messages could crash the delivery
123 process if the message IDs didn't exist for some reason. When
124 using 'split_spool_directory=yes' the construction of the spool
125 file name failed already, exposing the same netto behaviour.
126

127JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
128 mime_regex ACL conditions.

JH
130JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
131 to DSN fail messages (bounces): remote IP, remote greeting, remote response
132 to HELO, local diagnostic string.
133
805bb5c3
JH
134JH/05 Downgrade message for a TLS-certificate-based authentication fail from
135 log line to debug. Even when configured with a tls authenticator many
136 client connections are expected to not authenticate in this way, so
137 an authenticate fail is not an error.
138
56c2a7be
HSHR
139HS/02 Add the Exim version string to the process info. This way exiwhat
140 gives some more detail about the running daemon.
141

JH
142JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
143 matter for fast-change records such as DNSBLs.
144
6f6dedcc
JH
145JH/07 Bug 1678: Always record an interface option value, if set, as part of a
146 retry record, even if constant. There may be multiple transports with
147 different interface settings and the retry behaviour needs to be kept
148 distinct.
149
0f557e90
JH
150JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
151
152JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.

155
41e93589
JH
156JH/11 Bug 830: use same host for all RCPTS of a message, even under
157 hosts_randomize. This matters a lot when combined with mua_wrapper.
158
98b98887 159JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
376d2ec0

164JH/14 Change header file name for freeradius-client. Relevant if compiling
165 with Radius support; from the Gentoo tree and checked under Fedora.

JB
172JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
173
23f3dc67
JH
174JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
175 defaults to "*" (all hosts). The variable is now available when not built
176 with TLS, default unset, mainly to enable keeping the testuite sane.
177 If a server certificate is not supplied (via tls_certificate) an error is
178 logged, and clients will find TLS connections fail on startup. Presumably
179 they will retry in-clear.
180 Packagers of Exim are strongly encouraged to create a server certificate
181 at installation time.
182
240c288f
JH
183HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
184 with the $config_file variable.
185
5ef5dd52
JB
186JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
187 in transport context, after the attempt, and per-recipient. The latter type
188 is per host attempted. The event data is the error message, and the errno
189 information encodes the lookup type (A vs. MX) used for the (first) host,
190 and the trailing two digits of the smtp 4xx reponse.
191
e161710d
GF
192GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
193 to write to mainlog (or rejectlog, paniclog) in the window between file
194 creation and permissions/ownership being changed. Particularly affects
195 installations where exicyclog is run as root, rather than exim user;
196 result is that the running daemon panics and dies.

198JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
199
7f06582c
JH
200JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
201 selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
202 "pri" and "weight". Note that the previous implicit priority given by the
203 list order is no longer honoured.

211JH/26 Move PROXY support from Experimental to mainline, enabled for a build
212 by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
e6d2a989
JH
213 is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
214 variables are renamed to proxy_{local,external}_{address,port}.

JH
233JH/33 Bug 1748: Permit ACL dnslists= condition in non-smtp ACLs if explicit
234 keys are given for lookup.
235
f444c2c7
JH
236JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
237 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
238 only supported when built with TLS support. The PolarSSL SHA routines
239 are still used when the TLS library is too old for convenient support.
f444c2c7 240
a57b6200
JH
241JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
242 openssl_options), for security. OpenSSL forces this from version 1.1.0
243 server-side so match that on older versions.
244
07c73177 245JH/36 Bug 1778: longstanding bug in memory use by the ${run } expansion: A fresh
fa01e4f8 246 allocation for $value could be released as the expansion processing
07c73177 247 concluded, but leaving the global pointer active for it.
fa01e4f8 248

249JH/37 Bug 1769: Permit a VRFY ACL to override the default 252 response,
250 and to use the domains and local_parts ACL conditions.
251
1bc460a6
JH
252JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
253 incorrectly not doubled on cutthrough transmission, hence seen as a
254 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 255 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
256 via the normal store-and-forward channel. This could result in duplicates
257 received - but deduplicating mailstores were liable to retain only the
258 initial truncated version.
259

JH
271JH/43 Tidy coding issues detected by gcc --fsanitize=undefined. Some remain;
272 either intentional arithmetic overflow during PRNG, or testing config-
273 induced overflows.

275JH/44 Bug 1800: The combination of a -bhc commandline option and cutthrough
276 delivery resulted in actual delivery. Cancel cutthrough before DATA
277 stage.
278
f9334a28
JH
279JH/45 Fix cutthrough, when connection not opened by verify and target hard-
280 rejects a recipient: pass the reject to the originator.
281
dc8091e7
JH
282JH/46 Multiple issues raised by Coverity. Some were obvious or plausible bugs.
283 Many were false-positives and ignorable, but it's worth fixing the
284 former class.
285
dfe7d917
JH
286JH/47 Fix build on HP-UX and older Solaris, which need (un)setenv now also
287 for the new environment-manipulation done at startup. Move the routines
288 from being local to tls.c to being global via the os.c file.
289
93cc2d6e
JH
290JH/48 Bug 1807: Fix ${extract } for the numeric/3-string case. While preparsing
291 an extract embedded as result-arg for a map, the first arg for extract
292 is unavailable so we cannot tell if this is a numbered or keyed
293 extraction. Accept either.

392 Normally benign, it bites when the pair was led to by a CNAME;
393 modern usage is to not canoicalize the domain to a CNAME target
394 (and we were inconsistent anyway for A-only vs AAAA+A).

421TL/01 When running the test suite, the README says that variables such as
422 no_msglog_check are global and can be placed anywhere in a specific
423 test's script, however it was observed that placement needed to be near
424 the beginning for it to behave that way. Changed the runtest perl
425 script to read through the entire script once to detect and set these
426 variables, reset to the beginning of the script, and then run through
427 the script parsing/test process like normal.

785
786 When a queue runner is handling a message, Exim first routes the
787 recipient addresses, during which it prunes them based on the retry
788 hints database. After that it attempts to deliver the message to
789 any remaining recipients. It then updates the hints database using
790 the retry rules.
791
792 So if a recipient address works intermittently, it can get repeatedly
793 deferred at routing time. The retry hints record remains fresh so the
794 address never reaches the final cutoff time.
795
796 This is a fairly common occurrence when a user is bumping up against
797 their storage quota. Exim had some logic in its local delivery code
798 to deal with this. However it did not apply to per-recipient defers
799 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
800
1ddeb334
TF
801 This change adds a proper retry rule check during routing so that the
802 final cutoff time is checked against the message's age. We only do
803 this check if there is an address retry record and there is not a
804 domain retry record; this implies that previous attempts to handle
805 the address had the retry_use_local_parts option turned on. We use
806 this as an approximation for the destination being like a local
807 delivery, as in LMTP.
67bd1ab3
TF
808
809 I suspect this new check makes the old local delivery cutoff check
810 redundant, but I have not verified this so I left the code in place.

814 Test 0254 submits a message to Exim with the header
815
816 Resent-From: f
817
818 When I ran the test suite under the user fanf2, Exim expanded
819 the header to contain my full name, whereas it should have added
820 a Resent-Sender: header. It erroneously treats any prefix of the
821 username as equal to the username.

823 This change corrects that bug.

845 Server implementation by Todd Lyons, client by JH.
846 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
847 config variable "prdr_enable" controls whether the server
848 advertises the facility. If the client requests PRDR a new
849 acl_data_smtp_prdr ACL is called once for each recipient, after
850 the body content is received and before the acl_smtp_data ACL.
851 The client is controlled by bolth of: a hosts_try_prdr option
852 on the smtp transport, and the server advertisement.
853 Default client logging of deliveries and rejections involving
854 PRDR are flagged with the string "PRDR".

1132TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1133 lock up or crash if it happened to be inside a call to libc when it
1134 got a SIGUSR1 from exiwhat.
1135
1136 The SIGUSR1 handler appends the current process status to the process
1137 log which is later printed by exiwhat. It used to use the general
1138 purpose logging code to do this, but several functions it calls are
1139 not safe for signals.
1140
1141 The new output code in the SIGUSR1 handler is specific to the process
1142 log, and simple enough that it's easy to inspect for signal safety.
1143 Removing some special cases also simplifies the general logging code.
1144 Removing the spurious timestamps from the process log simplifies
1145 exiwhat.

TF
1147TF/04 Improved ratelimit ACL condition.
1148
1149 The /noupdate option has been deprecated in favour of /readonly which
1150 has clearer semantics. The /leaky, /strict, and /readonly update modes
1151 are mutually exclusive. The update mode is no longer included in the
1152 database key; it just determines when the database is updated. (This
1153 means that when you upgrde Exim will forget old rate measurements.)
1154
1155 Exim now checks that the per_* options are used with an update mode that
1156 makes sense for the current ACL. For example, when Exim is processing a
1157 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1158 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1159 must specify per_mail/readonly. If you omit the update mode it defaults to
1160 /leaky where that makes sense (as before) or /readonly where required.
1161
1162 The /noupdate option is now undocumented but still supported for
1163 backwards compatibility. It is equivalent to /readonly except that in
1164 ACLs where /readonly is required you may specify /leaky/noupdate or
1165 /strict/noupdate which are treated the same as /readonly.
1166
1167 A useful new feature is the /count= option. This is a generalization
1168 of the per_byte option, so that you can measure the throughput of other
1169 aggregate values. For example, the per_byte option is now equivalent
1170 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1171
1172 The per_rcpt option has been generalized using the /count= mechanism
1173 (though it's more complicated than the per_byte equivalence). When it is
1174 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1175 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1176 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1177 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1178 Note that using per_rcpt with a non-readonly update mode in more than
1179 one ACL will cause the recipients to be double-counted. (The per_mail
1180 and per_byte options don't have this problem.)
1181
1182 The handling of very low rates has changed slightly. If the computed rate
1183 is less than the event's count (usually one) then this event is the first
1184 after a long gap. In this case the rate is set to the same as this event's
1185 count, so that the first message of a spam run is counted properly.

1187 The major new feature is a mechanism for counting the rate of unique
1188 events. The new per_addr option counts the number of different
1189 recipients that someone has sent messages to in the last time period. It
1190 behaves like per_rcpt if all the recipient addresses are different, but
1191 duplicate recipient addresses do not increase the measured rate. Like
1192 the /count= option this is a general mechanism, so the per_addr option
1193 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1194 example, measure the rate that a client uses different sender addresses
1195 with the options per_mail/unique=$sender_address. There are further
1196 details in the main documentation.

1747 were called 'true' and it seems that C99 defines that as a reserved

1769
6a3bceb1
PH
1770PH/02 When an IPv6 address is converted to a string for single-key lookup
1771 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1772 dots are used instead of colons so that keys in lsearch files need not
1773 contain colons. This was done some time before quoting was made available
1774 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1775 (notated using the quote facility) so as to distinguish them from IPv4
1776 keys. This meant that lookups for IP addresses in host lists did not work
1777 for iplsearch lookups.
1778
1779 This has been fixed by arranging for IPv6 addresses to be expressed with
1780 colons if the lookup type is iplsearch. This is not incompatible, because
1781 previously such lookups could never work.
1782
1783 The situation is now rather anomolous, since one *can* have colons in
1784 ordinary lsearch keys. However, making the change in all cases is
1785 incompatible and would probably break a number of configurations.

1790MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1791 conversion specification without a maximum field width, thereby enabling
1792 a rogue spamd server to cause a buffer overflow. While nobody in their
1793 right mind would setup Exim to query an untrusted spamd server, an
1794 attacker that gains access to a server running spamd could potentially
1795 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1800MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1801 a directory entry by the name of the lookup key. Previously, if a
1802 symlink pointed to a non-existing file or a file in a directory that
1803 Exim lacked permissions to read, a lookup for a key matching that
1804 symlink would fail. Now it is enough that a matching directory entry
1805 exists, symlink or not. (Bugzilla 503.)

1988PH/29 SMTP synchronization checks are implemented when a command is read -
1989 there is a check that no more input is waiting when there shouldn't be

1991 some time before the response is written. In this time, more input might
1992 arrive, invalidly. So now there are extra checks after an ACL has run for
1993 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1994 pipelining has not been advertised.

2068 the response to the final '.' that terminates a message, but only in the
2069 case where the client has not sent further data following the '.'
2070 (unfortunately, this is allowed). However, in many cases there won't be
2071 any further data because there won't be any more messages to send. A call
2072 to select() can be used: if it shows that the input is "ready", there is
2073 either input waiting, or the socket has been closed. An attempt to read
2074 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2075 would have sent an OK response which the client would never have see.

2085
2086PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2087 fixed by 4.65/MH/01 (is this a record?) are fixed:
2088
2089 (i) An empty string was always treated as zero by the numeric comparison
2090 operators. This behaviour has been restored.
2091
2092 (ii) It is documented that the numeric comparison operators always treat
2093 their arguments as decimal numbers. This was broken in that numbers
2094 starting with 0 were being interpreted as octal.
2095
2096 While fixing these problems I realized that there was another issue that
2097 hadn't been noticed. Values of message_size_limit (both the global option
2098 and the transport option) were treated as octal if they started with 0.
2099 The documentation was vague. These values are now always treated as
2100 decimal, and I will make that clear in the documentation.

2116 is held in a short int, deliveries were likely to be lost. As such a
2117 large number of recipients for a single message is ridiculous
2118 (performance will be very, very poor), I have chosen to impose a limit
2119 rather than extend the field.

2135TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
2144PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2145 callout verification, Exim cached a "reject" for the entire domain. This
2146 is correct for most verifications, but it is not correct for a recipient
2147 verification with use_sender or use_postmaster set, because in that case
2148 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2149 case of MAIL FROM:<> rejection from other early rejections (e.g.
2150 rejection of HELO). When verifying a recipient using a non-null MAIL
2151 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2152 Whatever the result of the callout, the value of the domain cache is
2153 left unchanged (for any other kind of callout, getting as far as trying
2154 RCPT means that the domain itself is ok).

2188PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2190 probably the interface on which it is arriving) and not to the outgoing
2191 callout (which could be using a different interface). This has been
2192 changed to use the value of the helo_data option from the smtp transport
2193 instead - this is what is used when a message is actually being sent. If
2194 there is no remote transport (possible with a router that sets up host
2195 addresses), $smtp_active_hostname is used.

7befa435 2198 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2199 (a) The code assumed that strncpy() returns a negative number on buffer
2200 overflow, which isn't the case. Replaced with Exim's string_format()
2201 function.
2202 (b) There were several signed/unsigned issues. I just did the minimum
2203 hacking in of casts. There is scope for a larger refactoring.
2204 (c) The code used strcasecmp() which is not a standard C function.
2205 Replaced with Exim's strcmpic() function.
2206 (d) The code set only $1; it now sets $auth1 as well.
2207 (e) A simple test gave the error "authentication client didn't specify
2208 service in request". It would seem that Dovecot has changed its
2209 interface. Fortunately there's a specification; I followed it and
2210 changed what the client sends and it appears to be working now.

2215PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2216 address A is aliased to B and C, where B exists and C does not. Without
2217 -v the output is "A verified" because verification stops after a
2218 successful redirection if more than one address is generated. However,
2219 with -v the child addresses are also verified. Exim was outputting "A
2220 failed to verify" and then showing the successful verification for C,
2221 with its parentage. It now outputs "B failed to verify", showing B's
2222 parentage before showing the successful verification of C.

2225 look up a TXT record in a specific list after matching in a combined

2227
322050c2
PH
2228PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2229 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2230 they consult the DNS. I had assumed they would set it the way they
2231 wanted; and indeed my experiments on Linux seem to show that in some
2232 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2233 To be on the safe side, however, I have now made the interface to
2234 host_find_byname() similar to host_find_bydns(), with an argument
2235 containing the DNS resolver options. The host_find_byname() function now
2236 sets these options at its start, just as host_find_bydns() does. The smtp
2237 transport options dns_qualify_single and dns_search_parents are passed to
2238 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2239 of host_find_byname() use the default settings of RES_DEFNAMES
2240 (qualify_single) but not RES_DNSRCH (search_parents).

2242PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2243 spool_read_header() do less string testing, by means of a preliminary
2244 switch on the second character of optional "-foo" lines. (This is
2245 overdue, caused by the large number of possibilities that now exist.
2246 Originally there were few.) While I was there, I also converted the
2247 str(n)cmp tests so they don't re-test the leading "-" and the first
2248 character, in the hope this might squeeze out yet more improvement.

PH
2250PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2251 flag allowing group syntax was set by the header_syntax check but not
2252 turned off, possible causing trouble later; (2) The flag was not being
2253 set at all for the header_verify test, causing "group"-style headers to
2254 be rejected. I have now set it in this case, and also caused header_
2255 verify to ignore an empty address taken from a group. While doing this, I
2256 came across some other cases where the code for allowing group syntax
2257 while scanning a header line wasn't quite right (mostly, not resetting
2258 the flag correctly in the right place). These bugs could have caused
2259 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
2261PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2262 with the "reply" argument non-NULL. The code, however (which originally
2263 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2264 but it didn't always do it. This confused somebody who was copying the
2265 code for some other use. I have removed all the tests.

PH
2267PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2268 feature that was used to support insecure browsers during the U.S. crypto
2269 embargo. It requires special client support, and Exim is probably the
2270 only MTA that supported it -- and would never use it because real RSA is
2271 always available. This code has been removed, because it had the bad
2272 effect of slowing Exim down by computing (never used) parameters for the
2273 RSA_EXPORT functionality.

2278 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2279 if the connection is using TLS or if the remote IP is the same as the
2280 local IP, and the "valid-client-cert option" if a client certificate has
2281 been verified.

PH
2312
2313PH/30 Exim was sometimes attempting to deliver messages that had suffered
2314 address errors (4xx response to RCPT) over the same connection as other
2315 messages routed to the same hosts. Such deliveries are always "forced",
2316 so retry times are not inspected. This resulted in far too many retries
2317 for the affected addresses. The effect occurred only when there were more
2318 hosts than the hosts_max_try setting in the smtp transport when it had
2319 the 4xx errors. Those hosts that it had tried were not added to the list
2320 of hosts for which the message was waiting, so if all were tried, there
2321 was no problem. Two fixes have been applied:
2322
2323 (i) If there are any address or message errors in an SMTP delivery, none
2324 of the hosts (tried or untried) are now added to the list of hosts
2325 for which the message is waiting, so the message should not be a
2326 candidate for sending over the same connection that was used for a
2327 successful delivery of some other message. This seems entirely
2328 reasonable: after all the message is NOT "waiting for some host".
2329 This is so "obvious" that I'm not sure why it wasn't done
2330 previously. Hope I haven't missed anything, but it can't do any
2331 harm, as the worst effect is to miss an optimization.
2332
2333 (ii) If, despite (i), such a delivery is accidentally attempted, the
2334 routing retry time is respected, so at least it doesn't keep
2335 hammering the server.

PH
2356PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2357 runs only) independently of the message's sender address. This meant
2358 that, if the 4xx error was in fact related to the sender, a different
2359 message to the same recipient with a different sender could confuse
2360 things. In particualar, this can happen when sending to a greylisting
2361 server, but other circumstances could also provoke similar problems.
2362 I have changed the default so that the retry time for these errors is now
2363 based a combination of the sender and recipient addresses. This change
2364 can be overridden by setting address_retry_include_sender=false in the
2365 smtp transport.

2637 kind of temporary error. A kludge has been added to help with this.
2638 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2639 554 error is used if errno is still zero or contains ENOENT (which occurs

2721 in 4.61-PH/06
2722
424a1c63
PH
2723PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
2724 syntactically invalid From: or Reply-to: line, and a filter used this to
2725 generate an autoreply, and therefore failed to obtain an address for the
2726 autoreply, Exim could try to deliver to a non-existent relative file
2727 name, causing unrelated and misleading errors. What now happens is that
2728 it logs this as a hard delivery error, but does not attempt to create a
2729 bounce message.

PH
2731PH/11 The exinext utility has a -C option for testing purposes, but although
2732 the given file was scanned by exinext itself; it wasn't being passed on

PH
2738PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
2739 compiled. In many other places in Exim, IPv6 addresses are always
2740 recognized, so I have changed this. It also means that IPv4 domain
2741 literals of the form [IPV4:n.n.n.n] are now always recognized.

PH
2743PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
2744 used if the router is not running as root, for example, when verifying at
2745 ACL time, or when using -bh. The debugging output from this situation was
2746 non-existent - all you got was a failure to exec. I have made two
2747 changes:
2748
2749 (a) Failures to set uid/gid, the current directory, or a process leader
2750 in a subprocess such as that created by queryprogram now generate
2751 suitable debugging ouput when -d is set.
2752
2753 (b) The queryprogram router detects when it is not running as root,
2754 outputs suitable debugging information if -d is set, and then runs
2755 the subprocess without attempting to change uid/gid.

2757PH/15 Minor change to Makefile for building test_host (undocumented testing
2758 feature).
2759
1349e1e5
PH
2760PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2761 additional section of a DNS packet that returns MX or SRV records.
2762 Instead, it always explicitly searches for A/AAAA records. This avoids
2763 major problems that occur when a DNS server includes only records of one
2764 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2765 fixed another bug: if SRV records were looked up and the corresponding
2766 address records were *not* found in the additional section, the port
2767 values from the SRV records were lost.
2768
ea49d0e1
PH
2769PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
2770 using the correct key (the original address) when searching the retry
2771 rules in order to find which one to use for generating the retry hint.
2772
064a94c9
PH
2773PH/18 If quota_warn_message contains a From: header, Exim now refrains from
2774 adding the default one. Similarly, if it contains a Reply-To: header, the
2775 errors_reply_to option, if set, is not used.
2776
727071f8
PH
2777PH/19 When calculating a retry time, Exim used to measure the "time since
2778 failure" by looking at the "first failed" field in the retry record. Now
2779 it does not use this if it is later than than the arrival time of the
2780 message. Instead it uses the arrival time. This makes for better
2781 behaviour in cases where some deliveries succeed, thus re-setting the
2782 "first failed" field. An example is a quota failure for a huge message
2783 when small messages continue to be delivered. Without this change, the
2784 "time since failure" will always be short, possible causing more frequent
2785 delivery attempts for the huge message than are intended.

PH
2788PH/20 Added $auth1, $auth2, $auth3 to contain authentication data (as well as
2789 $1, $2, $3) because the numerical variables can be reset during some
2790 expansion items (e.g. "match"), thereby losing the authentication data.

2794
2795PH/22 Test the values given for quota, quota_filecount, quota_warn_threshold,
2796 mailbox_size, and mailbox_filecount in the appendfile transport. If a
2797 filecount value is greater than 2G or if a quota value is greater than 2G
2798 on a system where the size of off_t is not greater than 4, a panic error
2799 is given.

PH
2801PH/23 When a malformed item such as 1.2.3/24 appears in a host list, it can
2802 never match. The debug and -bh output now contains an explicit error
2803 message indicating a malformed IPv4 address or mask.
2804
2805PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
2806 1.2.3.4 without a mask. Now it is not recognized as an IP address, and
2807 PH/23 above applies.

PH
2809PH/25 Do not write to syslog when running in the test harness. The only

PH
2815PH/27 If a host name lookup failed very early in a connection, for example, if
2816 the IP address matched host_lookup and the reverse lookup yielded a name
2817 that did not have a forward lookup, an error message of the form "no IP
2818 address found for host xxx.xxx.xxx (during SMTP connection from NULL)"
2819 could be logged. Now it outputs the IP address instead of "NULL".

PH
2821PH/28 An enabling patch from MH: add new function child_open_exim2() which
2822 allows the sender and the authenticated sender to be set when
2823 submitting a message from within Exim. Since child_open_exim() is
2824 documented for local_scan(), the new function should be too.

2834PH/32 In November 2003, the code in Exim that added an empty Bcc: header when
2835 needed by RFC 822 but not by RFC 2822 was commented out. I have now
2836 tidied the source and removed it altogether.
2837

PH
2838PH/33 When a queue run was abandoned because the load average was too high, a
2839 log line was always written; now it is written only if the queue_run log
2840 selector is set. In addition, the log line for abandonment now contains
2841 information about the queue run such as the pid. This is always present
2842 in "start" and "stop" lines but was omitted from the "abandon" line.

230205fc
PH
2848PH/35 Change the default for dns_check_names_pattern to allow slashes within
2849 names, as there are now some PTR records that contain slashes. This check
2850 is only to protect against broken name servers that fall over on strange
2851 characters, so the fact that it applies to all lookups doesn't matter.
2852
75e0e026
PH
2853PH/36 Now that the new test suite is complete, we can remove some of the
2854 special code in Exim that was needed for the old test suite. For example,
2855 sorting DNS records because real resolvers return them in an arbitrary
2856 order. The new test suite's fake resolver always returns records in the
2857 same order.
2858
2859PH/37 When running in the test harness, use -odi for submitted messages (e.g.

2881
2632889e
PH
2882PH/42 The content-scanning code uses fopen() to create files in which to put
2883 message data. Previously it was not paying any attention to the mode of
2884 the files. Exim runs with umask(0) because the rest of the code creates
2885 files with open(), and sets the required mode explicitly. Thus, these
2886 files were ending up world-writeable. This was not a big issue, because,
2887 being within the spool directory, they were not world-accessible. I have
2888 created a function called modefopen, which takes an additional mode
2889 argument. It sets umask(777), creates the file, chmods it to the required
2890 mode, then resets the umask. All the relevant calls to fopen() in the
2891 content scanning code have been changed to use this function.
2892
944a9c55
PH
2893PH/43 If retry_interval_max is set greater than 24 hours, it is quietly reset

4730f942
PH
2899PH/45 When the plaintext authenticator is running as a client, the server's
2900 challenges are checked to ensure they are valid base64 strings. By
2901 default, the authentication attempt is cancelled if an invalid string is
2902 received. Setting client_ignore_invalid_base64 true ignores these errors.
2903 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2904 they are received. Thus, the responses can be made to depend on the
2905 challenges. If an invalid string is ignored, an empty string is placed in
2906 the variable.

PH
2917PH/50 When an Exim quota was set without a file count quota, and mailbox_size
2918 was also set, the appendfile transport was unnecessarily scanning a
2919 directory of message files (e.g. for maildir delivery) to find the count
2920 of files (along with the size), even though it did not need this
2921 information. It now does the scan only if it needs to find either the
2922 size of the count of files.

PH
2926PH/52 Two bugs concerned with error handling when the smtp transport is
2927 used in LMTP mode:
2928
2929 (i) Exim was not creating retry information for temporary errors given
2930 for individual recipients after the DATA command when the smtp transport
2931 was used in LMTP mode. This meant that they could be retried too
2932 frequently, and not timed out correctly.
2933
2934 (ii) Exim was setting the flag that allows error details to be returned
2935 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2936 recipients that were returned after the DATA command.
2937
2938PH/53 This is related to PH/52, but is more general: for any failing address,
2939 when detailed error information was permitted to be returned to the
2940 sender, but the error was temporary, then after the final timeout, only
2941 "retry timeout exceeded" was returned. Now it returns the full error as
2942 well as "retry timeout exceeded".

2998PH/68 The bounce_return_message and bounce_return_body options were not being
2999 honoured for bounces generated during the reception of non-SMTP messages.
3000 In particular, this applied to messages rejected by the ACL. This bug has
3001 been fixed. However, if bounce_return_message is true and bounce_return_
3002 body is false, the headers that are returned for a non-SMTP message
3003 include only those that have been read before the error was detected.

PH
3006PH/69 The HTML version of the specification is now built in a directory called

d515a917
PH
3012PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3013 function verify_get_ident() calls ip_connect() to connect a socket, but
3014 if the "connect()" function timed out, ip_connect() used to close the
3015 socket. However, verify_get_ident() also closes the socket later, and in
3016 between Exim writes to the log, which may get opened at this point. When
3017 the socket was closed in ip_connect(), the log could get the same file
3018 descriptor number as the socket. This naturally causes chaos. The fix is
3019 not to close the socket in ip_connect(); the socket should be closed by
3020 the function that creates it. There was only one place in the code where
3021 this was missing, in the iplookup router, which I don't think anybody now
3022 uses, but I've fixed it anyway.

3041PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3042
3043 (1) Generate an error if the third argument for the ${prvs expansion is
3044 not a single digit.
3045
3046 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3047 string.
3048
3049 (3) Reset the variables that are obtained from the first argument of
3050 ${prvscheck and used in the second argument before leaving the code,
3051 because their memory is reclaimed, so using them afterwards may do
3052 silly things.
3053
3054 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3055 one (it's much easier than Tom thought :-).
3056
3057 (5) Because of (4), we can now allow for the use of $prvscheck_result
3058 inside the third argument.

3069
3070 => >A.N.Other <ano@some.domain> <original@ddress> ...
3071
3072 This has been changed so that it extracts the operative address. There
3073 may be more than one such address. If so, they are comma-separated, like

PH
3078PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3079 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3080 not being looked up in the rDNS to get a host name, Exim was showing the
3081 IP address twice in Received: lines, even though the IP addresses were
3082 identical. For example:
3083
3084 Received: from [1.2.3.4] (helo=[1.2.3.4])
3085
3086 However, if the real host name was known, it was omitting the HELO data
3087 if it matched the actual IP address. This has been tidied up so that it
3088 doesn't show the same IP address twice.

3117 Auto-submitted: auto-generated
3118
3119 in the messages that it generates (bounce messages and others, such as
3120 warnings). In the case of bounce messages for non-SMTP mesages, there was
3121 also a typo: it was using "Auto_submitted" (underscore instead of
3122 hyphen). Since every message generated by Exim is necessarily in response
3123 to another message, thes have all been changed to:
3124
3125 Auto-Submitted: auto-replied
3126
3127 in accordance with these statements in the RFC:
3128
3129 The auto-replied keyword:
3130
3131 - SHOULD be used on messages sent in direct response to another
3132 message by an automatic process,
3133
3134 - MUST NOT be used on manually-generated messages,
3135
3136 - MAY be used on Delivery Status Notifications (DSNs) and Message
3137 Disposition Notifications (MDNs),
3138
3139 - MUST NOT be used on messages generated by automatic or periodic
3140 processes, except for messages which are automatic responses to
3141 other messages.

3162PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3163 extension "envelope-auth". The code is finished and in agreement with
3164 other implementations, but there is no documentation so far and in fact,
3165 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3166 not changing the active code.
3167
3168 Print executed "if" and "elsif" statements when debugging is used. This
3169 helps a great deal to understand what a filter does.

PH
3177PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3178 canonical form (as documented). However, after a host name lookup from
3179 the IP address, check_host() was doing a simple string comparison with
3180 addresses acquired from the DNS when checking that the found name did
3181 have the original IP as one of its addresses. Since any found IPv6
3182 addresses are likely to be in abbreviated form, the comparison could
3183 fail. Luckily, there already exists a function for doing the comparison
3184 by converting both addresses to binary, so now that is used instead of
3185 the text comparison.
3186
96776534
PH
3187PH/20 There was another similar case to PH/19, when a complete host name was
3188 given in a host list; looking up its IP address could give an abbreviated
3189 form, whereas the current host's name might or might not be abbreviated.
3190 The same fix has been applied.

3208 non-personal, in accordance with RFC 3834. (Previously it treated
3209 anything starting "auto-" as non-personal.)

3264PH/12 There was a missing call to search_tidyup() before the fork() in rda.c to

3269PH/13 Previously, if "verify = helo" was set in an ACL, the condition was true
3270 only if the host matched helo_try_verify_hosts, which caused the

3272 tested the remembered result. Now, if a previous verification attempt has
3273 not happened, "verify = helo" does it there and then.

3302PH/23 Applied a patch to fix problems with exim-4.52 while doing radius

3304
3305 - Error returned from rc_read_config was caught wrongly
3306 - Username/password not passed on to radius server due to wrong length.

3308 The presumption is that some radiusclient API changes for 4.51/PH/17
3309 were not taken care of correctly. The code is still untested by me (my
3310 Linux distribution still has 0.3.2 of radiusclient), but it was
