1Change log file for Exim from version 4.21
2-------------------------------------------
446415f5
HSHR
3This document describes *changes* to previous versions, that might
4affect Exim's operation, with an unchanged configuration file. For new
5options, and new features, see the NewStuff file next to this ChangeLog.
495ae4b0 6
fd047340 7Exim version 4.89
9427e879
JH
8-------------------
9JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
10 than -2003 did; needs libidn2 in addition to linidn.
fd047340 11
7b283890
JH
12JH/02 The path option on a pipe transport is now expanded before use.

15Exim version 4.88
16-----------------
9094b84b
JH
17JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
18 supports it and a size is available (ie. the sending peer gave us one).
8d042305 19
03d5892b
JH
20JH/02 The obsolete acl condition "demime" is removed (finally, after ten
21 years of being deprecated). The replacements are the ACLs
22 acl_smtp_mime and acl_not_smtp_mime.
23
4b0fe319
JH
24JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
25 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
26 or even an in-clear connection were permitted. Now, if the host lookup
27 was dnssec and dane was requested then the host is only used if the
28 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
29 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
30 if one fails this test.
31 This means that a poorly-configured remote DNS will make it incommunicado;
32 but it protects against a DNS-interception attack on it.
33
789f8a4f
JH
34JH/04 Bug 1810: make continued-use of an open smtp transport connection
35 non-noisy when a race steals the message being considered.
36
23bb6982 37JH/05 If main configuration option tls_certificate is unset, generate a
f59aaaaa 38 self-signed certificate for inbound TLS connections.
23bb6982 39
0bd1b1ed 40JH/06 Bug 165: hide more cases of password exposure - this time in expansions
f42deca9 41 in rewrites and routers.
0bd1b1ed 42
20b9a2dc
JH
43JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
44 and logged a warning sing 4.83; now they are a configuration file error.
45
05392bbc
JH
46JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
47 (lacking @domain). Apply the same qualification processing as RCPT.
48
1a6230a3
JH
49JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
50
cfab9d68
JH
51JH/10 Support ${sha256:} applied to a string (as well as the previous
52 certificate).
53
98c82a3d
JH
54JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
55 a cutthrough deliver is pending, as we always want to make a connection.
56 This also avoids re-routing the message when later placing the cutthrough
57 connection after a verify cache hit.
58 Do not update it with the verify result either.
59
60JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
61 when routing results in more than one destination address.
62
ae8386f0
JH
63JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
64 signing (which inhibits the cutthrough capability). Previously only
65 the presence of an option was tested; now an expansion evaluating as
66 empty is permissible (obviously it should depend only on data available
67 when the cutthrough connection is made).
68
0d9fa8c0
JH
69JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
70 the relevant preceding SMTP command did not note the pipelining mode.
71
3581f321
JH
72JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
73 Previously they were not counted.
74
ef3a1a30
JH
75JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
76 as one having no matching records. Previously we deferred the message
77 that needed the lookup.
78
803628d5 79JH/17 Fakereject: previously logged as a norml message arrival "<="; now
27b9e5f4
JH
80 distinguished as "(=".
81
1435d4b2
JH
82JH/18 Bug 1867: make the fail_defer_domains option on a dnslookup router work
83 for missing MX records. Previously it only worked for missing A records.
84
eea0defe
JB
85JH/19 Bug 1850: support Radius libraries that return REJECT_RC.
86
87JH/20 Bug 1872: Ensure that acl_smtp_notquit is run when the connection drops
88 after the data-go-ahead and data-ack. Patch from Jason Betts.

90JH/21 Bug 1846: Send DMARC forensic reports for reject and quaratine results,
91 even for a "none" policy. Patch from Tony Meyer.
92
1c788856
JH
93JH/22 Fix continued use of a connection for further deliveries. If a port was
94 specified by a router, it must also match for the delivery to be
95 compatible.
96
e3b1f624
JH
97JH/23 Bug 1874: fix continued use of a connection for further deliveries.
98 When one of the recipients of a message was unsuitable for the connection
99 (has no matching addresses), we lost track of needing to mark it
100 deferred. As a result mail would be lost.
101
a57ce043
JH
102JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
103
f59aaaaa 104JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
105 takes up less space and should be simpler to maintain. Merge the ACL
106 condition decode tables also, with similar effect.
d7bed771 107
d1f9fb42
JH
108JH/26 Fix problem with one_time used on a redirect router which returned the
109 parent address unchanged. A retry would see the parent address marked as
110 delivered, so not attempt the (identical) child. As a result mail would
111 be lost.
112
92b0827a
JH
113JH/27 Fix a possible security hole, wherein a process operating with the Exim
114 UID can gain a root shell. Credit to http://www.halfdog.net/ for
115 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
116 itself :(

ddf1b11a
JH
118JH/28 Enable {spool,log} filesystem space and inode checks as default.
119 Main config options check_{log,spool}_{inodes,space} are now
120 100 inodes, 10MB unless set otherwise in the configuration.

122JH/29 Fix the connection_reject log selector to apply to the connect ACL.
123 Previously it only applied to the main-section connection policy
124 options.

131PP/02 Unbreak build via pkg-config with new hash support when crypto headers
132 are not in the system include path.

ad7fc6eb 134JH/31 Fix longstanding bug with aborted TLS server connection handling. Under
f59aaaaa 135 GnuTLS, when a session startup failed (eg because the client disconnected)
ad7fc6eb
JH
136 Exim did stdio operations after fclose. This was exposed by a recent
137 change which nulled out the file handle after the fclose.
ad7fc6eb 138
ee5b1e28
JH
139JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
140 signed directly by the cert-signing cert, rather than an intermediate
141 OCSP-signing cert. This is the model used by LetsEncrypt.
142
5ddc9771
JH
143JH/33 Bug 1914: Ensure socket is nonblocking before draining after SMTP QUIT.

158Exim version 4.87
159-----------------
82d14d6a
JH
160JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
161 and 3.4.4 - once the server is enabled to respond to an OCSP request
162 it does even when not requested, resulting in a stapling non-aware
163 client dropping the TLS connection.

TF
165TF/01 Code cleanup: Overhaul the debug_selector and log_selector machinery to
166 support variable-length bit vectors. No functional change.
167
ac881e27
TF
168TF/02 Improve the consistency of logging incoming and outgoing interfaces.
169 The I= interface field on outgoing lines is now after the H= remote
170 host field, same as incoming lines. There is a separate
171 outgoing_interface log selector which allows you to disable the
172 outgoing I= field.
173
c8899c20
JH
174JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
175 If not running log_selector +smtp_connection the mainlog would be held
176 open indefinitely after a "too many connections" event, including to a
177 deleted file after a log rotate. Leave the per net connection logging
178 leaving it open for efficiency as that will be quickly detected by the
179 check on the next write.
180
f1b81d81
HSHR
181HS/01 Bug 1671: Fix post transport crash.
182 Processing the wait-<transport> messages could crash the delivery
183 process if the message IDs didn't exist for some reason. When
184 using 'split_spool_directory=yes' the construction of the spool
185 file name failed already, exposing the same netto behaviour.
186
f38917cc

188 mime_regex ACL conditions.

JH
190JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
191 to DSN fail messages (bounces): remote IP, remote greeting, remote response
192 to HELO, local diagnostic string.
193
805bb5c3
JH
194JH/05 Downgrade message for a TLS-certificate-based authentication fail from
195 log line to debug. Even when configured with a tls authenticator many
196 client connections are expected to not authenticate in this way, so
197 an authenticate fail is not an error.

199HS/02 Add the Exim version string to the process info. This way exiwhat
200 gives some more detail about the running daemon.

202JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
203 matter for fast-change records such as DNSBLs.
204
6f6dedcc
JH
205JH/07 Bug 1678: Always record an interface option value, if set, as part of a
206 retry record, even if constant. There may be multiple transports with
207 different interface settings and the retry behaviour needs to be kept
208 distinct.

JH
234JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
235 defaults to "*" (all hosts). The variable is now available when not built
236 with TLS, default unset, mainly to enable keeping the testuite sane.
237 If a server certificate is not supplied (via tls_certificate) an error is
238 logged, and clients will find TLS connections fail on startup. Presumably
239 they will retry in-clear.
240 Packagers of Exim are strongly encouraged to create a server certificate
241 at installation time.

243HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
244 with the $config_file variable.

5ef5dd52
JB
246JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
247 in transport context, after the attempt, and per-recipient. The latter type
248 is per host attempted. The event data is the error message, and the errno
249 information encodes the lookup type (A vs. MX) used for the (first) host,
250 and the trailing two digits of the smtp 4xx reponse.

GF
252GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
253 to write to mainlog (or rejectlog, paniclog) in the window between file
254 creation and permissions/ownership being changed. Particularly affects
255 installations where exicyclog is run as root, rather than exim user;
256 result is that the running daemon panics and dies.

f444c2c7
JH
296JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
297 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177
JH
298 only supported when built with TLS support. The PolarSSL SHA routines

JH
312JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
313 incorrectly not doubled on cutthrough transmission, hence seen as a
314 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 315 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6
JH
316 via the normal store-and-forward channel. This could result in duplicates
317 received - but deduplicating mailstores were liable to retain only the
318 initial truncated version.

01a4a5c5 367JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 368 is now done by default. The transport option tls_verify_cert_hostnames

844TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
845
846 When a queue runner is handling a message, Exim first routes the
847 recipient addresses, during which it prunes them based on the retry
848 hints database. After that it attempts to deliver the message to
849 any remaining recipients. It then updates the hints database using
850 the retry rules.
851
852 So if a recipient address works intermittently, it can get repeatedly
853 deferred at routing time. The retry hints record remains fresh so the
854 address never reaches the final cutoff time.
855
856 This is a fairly common occurrence when a user is bumping up against
857 their storage quota. Exim had some logic in its local delivery code
858 to deal with this. However it did not apply to per-recipient defers
859 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
860
1ddeb334
TF
861 This change adds a proper retry rule check during routing so that the
862 final cutoff time is checked against the message's age. We only do
863 this check if there is an address retry record and there is not a
864 domain retry record; this implies that previous attempts to handle
865 the address had the retry_use_local_parts option turned on. We use
866 this as an approximation for the destination being like a local
867 delivery, as in LMTP.
67bd1ab3
TF
868
869 I suspect this new check makes the old local delivery cutoff check
870 redundant, but I have not verified this so I left the code in place.

878 When I ran the test suite under the user fanf2, Exim expanded
879 the header to contain my full name, whereas it should have added
880 a Resent-Sender: header. It erroneously treats any prefix of the
881 username as equal to the username.

905 Server implementation by Todd Lyons, client by JH.
906 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
907 config variable "prdr_enable" controls whether the server
908 advertises the facility. If the client requests PRDR a new
909 acl_data_smtp_prdr ACL is called once for each recipient, after
910 the body content is received and before the acl_smtp_data ACL.
911 The client is controlled by bolth of: a hosts_try_prdr option
912 on the smtp transport, and the server advertisement.
913 Default client logging of deliveries and rejections involving
914 PRDR are flagged with the string "PRDR".

TF
1192TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1193 lock up or crash if it happened to be inside a call to libc when it
1194 got a SIGUSR1 from exiwhat.
1195
1196 The SIGUSR1 handler appends the current process status to the process
1197 log which is later printed by exiwhat. It used to use the general
1198 purpose logging code to do this, but several functions it calls are
1199 not safe for signals.
1200
1201 The new output code in the SIGUSR1 handler is specific to the process
1202 log, and simple enough that it's easy to inspect for signal safety.
1203 Removing some special cases also simplifies the general logging code.
1204 Removing the spurious timestamps from the process log simplifies
1205 exiwhat.

TF
1207TF/04 Improved ratelimit ACL condition.
1208
1209 The /noupdate option has been deprecated in favour of /readonly which
1210 has clearer semantics. The /leaky, /strict, and /readonly update modes
1211 are mutually exclusive. The update mode is no longer included in the
1212 database key; it just determines when the database is updated. (This
1213 means that when you upgrde Exim will forget old rate measurements.)
1214
1215 Exim now checks that the per_* options are used with an update mode that
1216 makes sense for the current ACL. For example, when Exim is processing a
1217 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1218 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1219 must specify per_mail/readonly. If you omit the update mode it defaults to
1220 /leaky where that makes sense (as before) or /readonly where required.
1221
1222 The /noupdate option is now undocumented but still supported for
1223 backwards compatibility. It is equivalent to /readonly except that in
1224 ACLs where /readonly is required you may specify /leaky/noupdate or
1225 /strict/noupdate which are treated the same as /readonly.
1226
1227 A useful new feature is the /count= option. This is a generalization
1228 of the per_byte option, so that you can measure the throughput of other
1229 aggregate values. For example, the per_byte option is now equivalent
1230 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1231
1232 The per_rcpt option has been generalized using the /count= mechanism
1233 (though it's more complicated than the per_byte equivalence). When it is
1234 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1235 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1236 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1237 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1238 Note that using per_rcpt with a non-readonly update mode in more than
1239 one ACL will cause the recipients to be double-counted. (The per_mail
1240 and per_byte options don't have this problem.)
1241
1242 The handling of very low rates has changed slightly. If the computed rate
1243 is less than the event's count (usually one) then this event is the first
1244 after a long gap. In this case the rate is set to the same as this event's
1245 count, so that the first message of a spam run is counted properly.
1246
1247 The major new feature is a mechanism for counting the rate of unique
1248 events. The new per_addr option counts the number of different
1249 recipients that someone has sent messages to in the last time period. It
1250 behaves like per_rcpt if all the recipient addresses are different, but
1251 duplicate recipient addresses do not increase the measured rate. Like
1252 the /count= option this is a general mechanism, so the per_addr option
1253 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1254 example, measure the rate that a client uses different sender addresses
1255 with the options per_mail/unique=$sender_address. There are further
1256 details in the main documentation.

1828PH/01 Another patch from the Sieve maintainer.
1829
6a3bceb1
PH
1830PH/02 When an IPv6 address is converted to a string for single-key lookup
1831 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1832 dots are used instead of colons so that keys in lsearch files need not
1833 contain colons. This was done some time before quoting was made available
1834 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1835 (notated using the quote facility) so as to distinguish them from IPv4
1836 keys. This meant that lookups for IP addresses in host lists did not work
1837 for iplsearch lookups.
1838
1839 This has been fixed by arranging for IPv6 addresses to be expressed with
1840 colons if the lookup type is iplsearch. This is not incompatible, because
1841 previously such lookups could never work.
1842
1843 The situation is now rather anomolous, since one *can* have colons in
1844 ordinary lsearch keys. However, making the change in all cases is
1845 incompatible and would probably break a number of configurations.

1850MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1851 conversion specification without a maximum field width, thereby enabling
1852 a rogue spamd server to cause a buffer overflow. While nobody in their
1853 right mind would setup Exim to query an untrusted spamd server, an
1854 attacker that gains access to a server running spamd could potentially
1855 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1860MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1861 a directory entry by the name of the lookup key. Previously, if a
1862 symlink pointed to a non-existing file or a file in a directory that
1863 Exim lacked permissions to read, a lookup for a key matching that
1864 symlink would fail. Now it is enough that a matching directory entry
1865 exists, symlink or not. (Bugzilla 503.)

2048PH/29 SMTP synchronization checks are implemented when a command is read -
2049 there is a check that no more input is waiting when there shouldn't be

2051 some time before the response is written. In this time, more input might
2052 arrive, invalidly. So now there are extra checks after an ACL has run for
2053 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2054 pipelining has not been advertised.

PH
2128 the response to the final '.' that terminates a message, but only in the
2129 case where the client has not sent further data following the '.'
2130 (unfortunately, this is allowed). However, in many cases there won't be
2131 any further data because there won't be any more messages to send. A call
2132 to select() can be used: if it shows that the input is "ready", there is
2133 either input waiting, or the socket has been closed. An attempt to read
2134 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2135 would have sent an OK response which the client would never have see.

2146PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2147 fixed by 4.65/MH/01 (is this a record?) are fixed:
2148
2149 (i) An empty string was always treated as zero by the numeric comparison
2150 operators. This behaviour has been restored.
2151
2152 (ii) It is documented that the numeric comparison operators always treat
2153 their arguments as decimal numbers. This was broken in that numbers
2154 starting with 0 were being interpreted as octal.
2155
2156 While fixing these problems I realized that there was another issue that
2157 hadn't been noticed. Values of message_size_limit (both the global option
2158 and the transport option) were treated as octal if they started with 0.
2159 The documentation was vague. These values are now always treated as
2160 decimal, and I will make that clear in the documentation.

2177 large number of recipients for a single message is ridiculous
2178 (performance will be very, very poor), I have chosen to impose a limit
2179 rather than extend the field.

2186 leftover -K file (the existence of which was triggered by #402).

PH
2204PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2205 callout verification, Exim cached a "reject" for the entire domain. This
2206 is correct for most verifications, but it is not correct for a recipient
2207 verification with use_sender or use_postmaster set, because in that case
2208 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2209 case of MAIL FROM:<> rejection from other early rejections (e.g.
2210 rejection of HELO). When verifying a recipient using a non-null MAIL
2211 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2212 Whatever the result of the callout, the value of the domain cache is
2213 left unchanged (for any other kind of callout, getting as far as trying
2214 RCPT means that the domain itself is ok).

2248PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2250 probably the interface on which it is arriving) and not to the outgoing
2251 callout (which could be using a different interface). This has been
2252 changed to use the value of the helo_data option from the smtp transport
2253 instead - this is what is used when a message is actually being sent. If
2254 there is no remote transport (possible with a router that sets up host
2255 addresses), $smtp_active_hostname is used.

7befa435 2258 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2259 (a) The code assumed that strncpy() returns a negative number on buffer
2260 overflow, which isn't the case. Replaced with Exim's string_format()
2261 function.
2262 (b) There were several signed/unsigned issues. I just did the minimum
2263 hacking in of casts. There is scope for a larger refactoring.
2264 (c) The code used strcasecmp() which is not a standard C function.
2265 Replaced with Exim's strcmpic() function.
2266 (d) The code set only $1; it now sets $auth1 as well.
2267 (e) A simple test gave the error "authentication client didn't specify
2268 service in request". It would seem that Dovecot has changed its
2269 interface. Fortunately there's a specification; I followed it and
2270 changed what the client sends and it appears to be working now.

2276 address A is aliased to B and C, where B exists and C does not. Without
2277 -v the output is "A verified" because verification stops after a
2278 successful redirection if more than one address is generated. However,
2279 with -v the child addresses are also verified. Exim was outputting "A
2280 failed to verify" and then showing the successful verification for C,
2281 with its parentage. It now outputs "B failed to verify", showing B's
2282 parentage before showing the successful verification of C.

322050c2
PH
2288PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2289 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2290 they consult the DNS. I had assumed they would set it the way they
2291 wanted; and indeed my experiments on Linux seem to show that in some
2292 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2293 To be on the safe side, however, I have now made the interface to
2294 host_find_byname() similar to host_find_bydns(), with an argument
2295 containing the DNS resolver options. The host_find_byname() function now
2296 sets these options at its start, just as host_find_bydns() does. The smtp
2297 transport options dns_qualify_single and dns_search_parents are passed to
2298 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2299 of host_find_byname() use the default settings of RES_DEFNAMES
2300 (qualify_single) but not RES_DNSRCH (search_parents).

2303 spool_read_header() do less string testing, by means of a preliminary
2304 switch on the second character of optional "-foo" lines. (This is
2305 overdue, caused by the large number of possibilities that now exist.
2306 Originally there were few.) While I was there, I also converted the
2307 str(n)cmp tests so they don't re-test the leading "-" and the first
2308 character, in the hope this might squeeze out yet more improvement.

2310PH/18 Two problems with "group" syntax in header lines when verifying: (1) The

2313 set at all for the header_verify test, causing "group"-style headers to
2314 be rejected. I have now set it in this case, and also caused header_
2315 verify to ignore an empty address taken from a group. While doing this, I
2316 came across some other cases where the code for allowing group syntax
2317 while scanning a header line wasn't quite right (mostly, not resetting
2318 the flag correctly in the right place). These bugs could have caused
2319 trouble for malformed header lines. I hope it is now all correct.

2323 came from elsewhere) had *some* tests for NULL when it wrote to *reply,

2327PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2328 feature that was used to support insecure browsers during the U.S. crypto
2329 embargo. It requires special client support, and Exim is probably the
2330 only MTA that supported it -- and would never use it because real RSA is
2331 always available. This code has been removed, because it had the bad
2332 effect of slowing Exim down by computing (never used) parameters for the
2333 RSA_EXPORT functionality.

2335PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2336 authenticator to fail if there's a tab character in the incoming data
2337 (there should never be unless someone is messing about, as it's supposed
2338 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2339 if the connection is using TLS or if the remote IP is the same as the
2340 local IP, and the "valid-client-cert option" if a client certificate has
2341 been verified.

2372
2373PH/30 Exim was sometimes attempting to deliver messages that had suffered
2374 address errors (4xx response to RCPT) over the same connection as other
2375 messages routed to the same hosts. Such deliveries are always "forced",
2376 so retry times are not inspected. This resulted in far too many retries
2377 for the affected addresses. The effect occurred only when there were more
2378 hosts than the hosts_max_try setting in the smtp transport when it had
2379 the 4xx errors. Those hosts that it had tried were not added to the list
2380 of hosts for which the message was waiting, so if all were tried, there
2381 was no problem. Two fixes have been applied:
2382
2383 (i) If there are any address or message errors in an SMTP delivery, none
2384 of the hosts (tried or untried) are now added to the list of hosts
2385 for which the message is waiting, so the message should not be a
2386 candidate for sending over the same connection that was used for a
2387 successful delivery of some other message. This seems entirely
2388 reasonable: after all the message is NOT "waiting for some host".
2389 This is so "obvious" that I'm not sure why it wasn't done
2390 previously. Hope I haven't missed anything, but it can't do any
2391 harm, as the worst effect is to miss an optimization.
2392
2393 (ii) If, despite (i), such a delivery is accidentally attempted, the
2394 routing retry time is respected, so at least it doesn't keep
2395 hammering the server.

2410PH/35 The error "getsockname() failed: connection reset by peer" was being
2411 written to the panic log as well as the main log, but it isn't really
2412 panic-worthy as it just means the connection died rather early on. I have
2413 removed the panic log writing for the ECONNRESET error when getsockname()
2414 fails.
2415
48c7f9e2
PH
2416PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2417 runs only) independently of the message's sender address. This meant
2418 that, if the 4xx error was in fact related to the sender, a different
2419 message to the same recipient with a different sender could confuse
2420 things. In particualar, this can happen when sending to a greylisting
2421 server, but other circumstances could also provoke similar problems.
2422 I have changed the default so that the retry time for these errors is now
2423 based a combination of the sender and recipient addresses. This change
2424 can be overridden by setting address_retry_include_sender=false in the
2425 smtp transport.

2698 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2699 554 error is used if errno is still zero or contains ENOENT (which occurs

2723PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2724 folder from quota calculations, a direct delivery into this folder messed
2725 up the contents of the maildirsize file. This was because the regex was
2726 used only to exclude .Trash (or whatever) when the size of the mailbox
2727 was calculated. There was no check that a delivery was happening into an

2737PH/01 The code for finding all the local interface addresses on a FreeBSD
2738 system running IPv6 was broken. This may well have applied to all BSD
2739 systems, as well as to others that have similar system calls. The broken
2740 code found IPv4 interfaces correctly, but gave incorrect values for the
2741 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2742 that it would not match correctly against @[] and not recognize the IPv6
2743 addresses as local.

2822 Instead, it always explicitly searches for A/AAAA records. This avoids
2823 major problems that occur when a DNS server includes only records of one
2824 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2825 fixed another bug: if SRV records were looked up and the corresponding
2826 address records were *not* found in the additional section, the port
2827 values from the SRV records were lost.

2837PH/19 When calculating a retry time, Exim used to measure the "time since
2838 failure" by looking at the "first failed" field in the retry record. Now
2839 it does not use this if it is later than than the arrival time of the
2840 message. Instead it uses the arrival time. This makes for better
2841 behaviour in cases where some deliveries succeed, thus re-setting the
2842 "first failed" field. An example is a quota failure for a huge message
2843 when small messages continue to be delivered. Without this change, the
2844 "time since failure" will always be short, possible causing more frequent
2845 delivery attempts for the huge message than are intended.

2942PH/42 The content-scanning code uses fopen() to create files in which to put
2943 message data. Previously it was not paying any attention to the mode of
2944 the files. Exim runs with umask(0) because the rest of the code creates
2945 files with open(), and sets the required mode explicitly. Thus, these
2946 files were ending up world-writeable. This was not a big issue, because,
2947 being within the spool directory, they were not world-accessible. I have
2948 created a function called modefopen, which takes an additional mode
2949 argument. It sets umask(777), creates the file, chmods it to the required
2950 mode, then resets the umask. All the relevant calls to fopen() in the

2991 was used in LMTP mode. This meant that they could be retried too
2992 frequently, and not timed out correctly.
2993
2994 (ii) Exim was setting the flag that allows error details to be returned
2995 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2996 recipients that were returned after the DATA command.
2997
2998PH/53 This is related to PH/52, but is more general: for any failing address,
2999 when detailed error information was permitted to be returned to the

3073 function verify_get_ident() calls ip_connect() to connect a socket, but
3074 if the "connect()" function timed out, ip_connect() used to close the
3075 socket. However, verify_get_ident() also closes the socket later, and in
3076 between Exim writes to the log, which may get opened at this point. When
3077 the socket was closed in ip_connect(), the log could get the same file
3078 descriptor number as the socket. This naturally causes chaos. The fix is
3079 not to close the socket in ip_connect(); the socket should be closed by
3080 the function that creates it. There was only one place in the code where
3081 this was missing, in the iplookup router, which I don't think anybody now

3101PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3102
3103 (1) Generate an error if the third argument for the ${prvs expansion is
3104 not a single digit.
3105
3106 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3107 string.
3108
3109 (3) Reset the variables that are obtained from the first argument of
3110 ${prvscheck and used in the second argument before leaving the code,
3111 because their memory is reclaimed, so using them afterwards may do
3112 silly things.
3113
3114 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3115 one (it's much easier than Tom thought :-).
3116
3117 (5) Because of (4), we can now allow for the use of $prvscheck_result
3118 inside the third argument.

3127PH/05 When a filter generated an autoreply, the entire To: header line was
3128 quoted in the delivery log line, like this:
3129
3130 => >A.N.Other <ano@some.domain> <original@ddress> ...
3131
3132 This has been changed so that it extracts the operative address. There
3133 may be more than one such address. If so, they are comma-separated, like
3134 this:
3135
3136 => >ano@some.domain,ona@other.domain <original@ddress> ...

3138PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3139 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3140 not being looked up in the rDNS to get a host name, Exim was showing the
3141 IP address twice in Received: lines, even though the IP addresses were
3142 identical. For example:
3143
3144 Received: from [1.2.3.4] (helo=[1.2.3.4])
3145
3146 However, if the real host name was known, it was omitting the HELO data
3147 if it matched the actual IP address. This has been tidied up so that it
3148 doesn't show the same IP address twice.

3150PH/07 When both +timestamp and +memory debugging was on, the value given by

3174PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3175 Electronic Mail") by including:
3176
3177 Auto-submitted: auto-generated
3178
3179 in the messages that it generates (bounce messages and others, such as
3180 warnings). In the case of bounce messages for non-SMTP mesages, there was
3181 also a typo: it was using "Auto_submitted" (underscore instead of
3182 hyphen). Since every message generated by Exim is necessarily in response
3183 to another message, thes have all been changed to:
3184
3185 Auto-Submitted: auto-replied
3186
3187 in accordance with these statements in the RFC:
3188
3189 The auto-replied keyword:
3190
3191 - SHOULD be used on messages sent in direct response to another
3192 message by an automatic process,
3193
3194 - MUST NOT be used on manually-generated messages,
3195
3196 - MAY be used on Delivery Status Notifications (DSNs) and Message
3197 Disposition Notifications (MDNs),
3198
3199 - MUST NOT be used on messages generated by automatic or periodic
3200 processes, except for messages which are automatic responses to
3201 other messages.

3222PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3223 extension "envelope-auth". The code is finished and in agreement with
3224 other implementations, but there is no documentation so far and in fact,
3225 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3226 not changing the active code.
3227
3228 Print executed "if" and "elsif" statements when debugging is used. This
3229 helps a great deal to understand what a filter does.

3237PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3238 canonical form (as documented). However, after a host name lookup from
3239 the IP address, check_host() was doing a simple string comparison with
3240 addresses acquired from the DNS when checking that the found name did
3241 have the original IP as one of its addresses. Since any found IPv6
3242 addresses are likely to be in abbreviated form, the comparison could
3243 fail. Luckily, there already exists a function for doing the comparison
3244 by converting both addresses to binary, so now that is used instead of
3245 the text comparison.

PH
3247PH/20 There was another similar case to PH/19, when a complete host name was
3248 given in a host list; looking up its IP address could give an abbreviated

3250 The same fix has been applied.
