9427e879
JH
11JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
12 than -2003 did; needs libidn2 in addition to linidn.

19JH/03 Bug 2003: fix Proxy Protocol v2 handling: the address size field was
20 missing a wire-to-host endian conversion.

JH
22JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
23 close after a BDAT command line could be taken as a following command,
24 giving a synch failure. Fix by only checking for synch immediately
25 before acknowledging the chunk.

29-----------------
4c57a40e 30

JH
31JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
32 supports it and a size is available (ie. the sending peer gave us one).
8d042305 33
03d5892b
JH
34JH/02 The obsolete acl condition "demime" is removed (finally, after ten
35 years of being deprecated). The replacements are the ACLs
36 acl_smtp_mime and acl_not_smtp_mime.
37
4b0fe319
JH
38JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
39 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
40 or even an in-clear connection were permitted. Now, if the host lookup
41 was dnssec and dane was requested then the host is only used if the
42 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
43 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
44 if one fails this test.
45 This means that a poorly-configured remote DNS will make it incommunicado;
46 but it protects against a DNS-interception attack on it.

48JH/04 Bug 1810: make continued-use of an open smtp transport connection
49 non-noisy when a race steals the message being considered.
50

f59aaaaa 52 self-signed certificate for inbound TLS connections.

f42deca9 55 in rewrites and routers.

20b9a2dc
JH
57JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
58 and logged a warning sing 4.83; now they are a configuration file error.
59

JH
60JH/08 Bug 1836: Fix crash in VRFY handling when handed an unqualified name
61 (lacking @domain). Apply the same qualification processing as RCPT.
62
1a6230a3
JH
63JH/09 Bug 1804: Avoid writing msglog files when in -bh or -bhc mode.
64
cfab9d68
JH
65JH/10 Support ${sha256:} applied to a string (as well as the previous
66 certificate).
67
98c82a3d
JH
68JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
69 a cutthrough deliver is pending, as we always want to make a connection.
70 This also avoids re-routing the message when later placing the cutthrough
71 connection after a verify cache hit.
72 Do not update it with the verify result either.
73
74JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
75 when routing results in more than one destination address.
76
ae8386f0
JH
77JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
78 signing (which inhibits the cutthrough capability). Previously only
79 the presence of an option was tested; now an expansion evaluating as
80 empty is permissible (obviously it should depend only on data available
81 when the cutthrough connection is made).
82
0d9fa8c0
JH
83JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
84 the relevant preceding SMTP command did not note the pipelining mode.
85

86JH/15 Fix counting of empty lines in $body_linecount and $message_linecount.
87 Previously they were not counted.
88

JH
89JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
90 as one having no matching records. Previously we deferred the message
91 that needed the lookup.
92
803628d5 93JH/17 Fakereject: previously logged as a norml message arrival "<="; now

102 after the data-go-ahead and data-ack. Patch from Jason Betts.

105 even for a "none" policy. Patch from Tony Meyer.
106
1c788856
JH
107JH/22 Fix continued use of a connection for further deliveries. If a port was
108 specified by a router, it must also match for the delivery to be
109 compatible.
110
e3b1f624
JH
111JH/23 Bug 1874: fix continued use of a connection for further deliveries.
112 When one of the recipients of a message was unsuitable for the connection
113 (has no matching addresses), we lost track of needing to mark it
114 deferred. As a result mail would be lost.

116JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
117
f59aaaaa 118JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
119 takes up less space and should be simpler to maintain. Merge the ACL
120 condition decode tables also, with similar effect.
d7bed771 121
d1f9fb42
JH
122JH/26 Fix problem with one_time used on a redirect router which returned the
123 parent address unchanged. A retry would see the parent address marked as
124 delivered, so not attempt the (identical) child. As a result mail would
125 be lost.

JH
127JH/27 Fix a possible security hole, wherein a process operating with the Exim
128 UID can gain a root shell. Credit to http://www.halfdog.net/ for
129 discovery and writeup. Ubuntu bug 1580454; no bug raised against Exim
130 itself :(

f59aaaaa 149 GnuTLS, when a session startup failed (eg because the client disconnected)
ad7fc6eb
JH
150 Exim did stdio operations after fclose. This was exposed by a recent
151 change which nulled out the file handle after the fclose.

153JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
154 signed directly by the cert-signing cert, rather than an intermediate
155 OCSP-signing cert. This is the model used by LetsEncrypt.

82d14d6a
JH
175JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
176 and 3.4.4 - once the server is enabled to respond to an OCSP request
177 it does even when not requested, resulting in a stapling non-aware
178 client dropping the TLS connection.

181 support variable-length bit vectors. No functional change.

ac881e27
TF
183TF/02 Improve the consistency of logging incoming and outgoing interfaces.
184 The I= interface field on outgoing lines is now after the H= remote
185 host field, same as incoming lines. There is a separate
186 outgoing_interface log selector which allows you to disable the
187 outgoing I= field.

c8899c20
JH
189JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
190 If not running log_selector +smtp_connection the mainlog would be held
191 open indefinitely after a "too many connections" event, including to a
192 deleted file after a log rotate. Leave the per net connection logging
193 leaving it open for efficiency as that will be quickly detected by the
194 check on the next write.

HSHR
196HS/01 Bug 1671: Fix post transport crash.
197 Processing the wait-<transport> messages could crash the delivery
198 process if the message IDs didn't exist for some reason. When
199 using 'split_spool_directory=yes' the construction of the spool
200 file name failed already, exposing the same netto behaviour.

205JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
206 to DSN fail messages (bounces): remote IP, remote greeting, remote response
207 to HELO, local diagnostic string.
208
805bb5c3
JH
209JH/05 Downgrade message for a TLS-certificate-based authentication fail from
210 log line to debug. Even when configured with a tls authenticator many
211 client connections are expected to not authenticate in this way, so
212 an authenticate fail is not an error.
213

214HS/02 Add the Exim version string to the process info. This way exiwhat
215 gives some more detail about the running daemon.

217JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
218 matter for fast-change records such as DNSBLs.
219
6f6dedcc
JH
220JH/07 Bug 1678: Always record an interface option value, if set, as part of a
221 retry record, even if constant. There may be multiple transports with
222 different interface settings and the retry behaviour needs to be kept
223 distinct.

JH
249JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
250 defaults to "*" (all hosts). The variable is now available when not built
251 with TLS, default unset, mainly to enable keeping the testuite sane.
252 If a server certificate is not supplied (via tls_certificate) an error is
253 logged, and clients will find TLS connections fail on startup. Presumably
254 they will retry in-clear.
255 Packagers of Exim are strongly encouraged to create a server certificate
256 at installation time.
257

258HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
259 with the $config_file variable.

5ef5dd52
JB
261JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
262 in transport context, after the attempt, and per-recipient. The latter type
263 is per host attempted. The event data is the error message, and the errno
264 information encodes the lookup type (A vs. MX) used for the (first) host,
265 and the trailing two digits of the smtp 4xx reponse.
266

GF
267GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
268 to write to mainlog (or rejectlog, paniclog) in the window between file
269 creation and permissions/ownership being changed. Particularly affects
270 installations where exicyclog is run as root, rather than exim user;
271 result is that the running daemon panics and dies.

311JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
312 support, by using OpenSSL or GnuTLS library ones. This means DKIM is
07c73177

313 only supported when built with TLS support. The PolarSSL SHA routines

JH
327JH/38 Fix cutthrough bug with body lines having a single dot. The dot was
328 incorrectly not doubled on cutthrough transmission, hence seen as a
329 body-termination at the receiving system - resulting in truncated mails.
62ac2eb7 330 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6

331 via the normal store-and-forward channel. This could result in duplicates
332 received - but deduplicating mailstores were liable to retain only the

860TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
861
862 When a queue runner is handling a message, Exim first routes the
863 recipient addresses, during which it prunes them based on the retry
864 hints database. After that it attempts to deliver the message to
865 any remaining recipients. It then updates the hints database using
866 the retry rules.
867
868 So if a recipient address works intermittently, it can get repeatedly
869 deferred at routing time. The retry hints record remains fresh so the
870 address never reaches the final cutoff time.
871
872 This is a fairly common occurrence when a user is bumping up against
873 their storage quota. Exim had some logic in its local delivery code
874 to deal with this. However it did not apply to per-recipient defers
875 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
876
1ddeb334
TF
877 This change adds a proper retry rule check during routing so that the
878 final cutoff time is checked against the message's age. We only do
879 this check if there is an address retry record and there is not a
880 domain retry record; this implies that previous attempts to handle
881 the address had the retry_use_local_parts option turned on. We use
882 this as an approximation for the destination being like a local
883 delivery, as in LMTP.
67bd1ab3
TF
884
885 I suspect this new check makes the old local delivery cutoff check
886 redundant, but I have not verified this so I left the code in place.

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

921 Server implementation by Todd Lyons, client by JH.
922 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
923 config variable "prdr_enable" controls whether the server
924 advertises the facility. If the client requests PRDR a new
925 acl_data_smtp_prdr ACL is called once for each recipient, after
926 the body content is received and before the acl_smtp_data ACL.
927 The client is controlled by bolth of: a hosts_try_prdr option
928 on the smtp transport, and the server advertisement.
929 Default client logging of deliveries and rejections involving
930 PRDR are flagged with the string "PRDR".

1208TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1209 lock up or crash if it happened to be inside a call to libc when it
1210 got a SIGUSR1 from exiwhat.
1211
1212 The SIGUSR1 handler appends the current process status to the process
1213 log which is later printed by exiwhat. It used to use the general
1214 purpose logging code to do this, but several functions it calls are
1215 not safe for signals.
1216
1217 The new output code in the SIGUSR1 handler is specific to the process
1218 log, and simple enough that it's easy to inspect for signal safety.
1219 Removing some special cases also simplifies the general logging code.
1220 Removing the spurious timestamps from the process log simplifies
1221 exiwhat.

1223TF/04 Improved ratelimit ACL condition.
1224
1225 The /noupdate option has been deprecated in favour of /readonly which
1226 has clearer semantics. The /leaky, /strict, and /readonly update modes
1227 are mutually exclusive. The update mode is no longer included in the
1228 database key; it just determines when the database is updated. (This
1229 means that when you upgrde Exim will forget old rate measurements.)
1230
1231 Exim now checks that the per_* options are used with an update mode that
1232 makes sense for the current ACL. For example, when Exim is processing a
1233 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1234 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1235 must specify per_mail/readonly. If you omit the update mode it defaults to
1236 /leaky where that makes sense (as before) or /readonly where required.
1237
1238 The /noupdate option is now undocumented but still supported for
1239 backwards compatibility. It is equivalent to /readonly except that in
1240 ACLs where /readonly is required you may specify /leaky/noupdate or
1241 /strict/noupdate which are treated the same as /readonly.
1242
1243 A useful new feature is the /count= option. This is a generalization
1244 of the per_byte option, so that you can measure the throughput of other
1245 aggregate values. For example, the per_byte option is now equivalent
1246 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1247
1248 The per_rcpt option has been generalized using the /count= mechanism
1249 (though it's more complicated than the per_byte equivalence). When it is
1250 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1251 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1252 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1253 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1254 Note that using per_rcpt with a non-readonly update mode in more than
1255 one ACL will cause the recipients to be double-counted. (The per_mail
1256 and per_byte options don't have this problem.)
1257
1258 The handling of very low rates has changed slightly. If the computed rate
1259 is less than the event's count (usually one) then this event is the first
1260 after a long gap. In this case the rate is set to the same as this event's
1261 count, so that the first message of a spam run is counted properly.
1262
1263 The major new feature is a mechanism for counting the rate of unique
1264 events. The new per_addr option counts the number of different
1265 recipients that someone has sent messages to in the last time period. It
1266 behaves like per_rcpt if all the recipient addresses are different, but
1267 duplicate recipient addresses do not increase the measured rate. Like
1268 the /count= option this is a general mechanism, so the per_addr option
1269 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1270 example, measure the rate that a client uses different sender addresses
1271 with the options per_mail/unique=$sender_address. There are further
1272 details in the main documentation.

1842-----------------
1843
1844PH/01 Another patch from the Sieve maintainer.
1845
6a3bceb1
PH
1846PH/02 When an IPv6 address is converted to a string for single-key lookup
1847 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1848 dots are used instead of colons so that keys in lsearch files need not
1849 contain colons. This was done some time before quoting was made available
1850 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1851 (notated using the quote facility) so as to distinguish them from IPv4
1852 keys. This meant that lookups for IP addresses in host lists did not work
1853 for iplsearch lookups.
1854
1855 This has been fixed by arranging for IPv6 addresses to be expressed with
1856 colons if the lookup type is iplsearch. This is not incompatible, because
1857 previously such lookups could never work.
1858
1859 The situation is now rather anomolous, since one *can* have colons in
1860 ordinary lsearch keys. However, making the change in all cases is
1861 incompatible and would probably break a number of configurations.

MH
1866MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1867 conversion specification without a maximum field width, thereby enabling
1868 a rogue spamd server to cause a buffer overflow. While nobody in their
1869 right mind would setup Exim to query an untrusted spamd server, an
1870 attacker that gains access to a server running spamd could potentially
1871 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1876MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1877 a directory entry by the name of the lookup key. Previously, if a
1878 symlink pointed to a non-existing file or a file in a directory that
1879 Exim lacked permissions to read, a lookup for a key matching that
1880 symlink would fail. Now it is enough that a matching directory entry
1881 exists, symlink or not. (Bugzilla 503.)

1958 if a client was not listed at all, or was listed with a value other than

PH
2064PH/29 SMTP synchronization checks are implemented when a command is read -
2065 there is a check that no more input is waiting when there shouldn't be
2066 any. However, for some commands, a delay in an ACL can mean that it is
2067 some time before the response is written. In this time, more input might
2068 arrive, invalidly. So now there are extra checks after an ACL has run for
2069 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2070 pipelining has not been advertised.

2085 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
2086 was a macro that became an assignment, so it seemed to work. This has

PH
2144 the response to the final '.' that terminates a message, but only in the
2145 case where the client has not sent further data following the '.'
2146 (unfortunately, this is allowed). However, in many cases there won't be
2147 any further data because there won't be any more messages to send. A call
2148 to select() can be used: if it shows that the input is "ready", there is
2149 either input waiting, or the socket has been closed. An attempt to read
2150 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2151 would have sent an OK response which the client would never have see.

2162PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2163 fixed by 4.65/MH/01 (is this a record?) are fixed:
2164
2165 (i) An empty string was always treated as zero by the numeric comparison
2166 operators. This behaviour has been restored.
2167
2168 (ii) It is documented that the numeric comparison operators always treat
2169 their arguments as decimal numbers. This was broken in that numbers
2170 starting with 0 were being interpreted as octal.
2171
2172 While fixing these problems I realized that there was another issue that
2173 hadn't been noticed. Values of message_size_limit (both the global option
2174 and the transport option) were treated as octal if they started with 0.
2175 The documentation was vague. These values are now always treated as
2176 decimal, and I will make that clear in the documentation.

2192 is held in a short int, deliveries were likely to be lost. As such a
2193 large number of recipients for a single message is ridiculous
2194 (performance will be very, very poor), I have chosen to impose a limit
2195 rather than extend the field.

2201TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
2202 leftover -K file (the existence of which was triggered by #402).

2211TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
2220PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2221 callout verification, Exim cached a "reject" for the entire domain. This
2222 is correct for most verifications, but it is not correct for a recipient
2223 verification with use_sender or use_postmaster set, because in that case
2224 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2225 case of MAIL FROM:<> rejection from other early rejections (e.g.
2226 rejection of HELO). When verifying a recipient using a non-null MAIL
2227 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2228 Whatever the result of the callout, the value of the domain cache is
2229 left unchanged (for any other kind of callout, getting as far as trying
2230 RCPT means that the domain itself is ok).

2264PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

2266 probably the interface on which it is arriving) and not to the outgoing
2267 callout (which could be using a different interface). This has been
2268 changed to use the value of the helo_data option from the smtp transport
2269 instead - this is what is used when a message is actually being sent. If
2270 there is no remote transport (possible with a router that sets up host
2271 addresses), $smtp_active_hostname is used.

7befa435 2274 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2275 (a) The code assumed that strncpy() returns a negative number on buffer
2276 overflow, which isn't the case. Replaced with Exim's string_format()
2277 function.
2278 (b) There were several signed/unsigned issues. I just did the minimum
2279 hacking in of casts. There is scope for a larger refactoring.
2280 (c) The code used strcasecmp() which is not a standard C function.
2281 Replaced with Exim's strcmpic() function.
2282 (d) The code set only $1; it now sets $auth1 as well.
2283 (e) A simple test gave the error "authentication client didn't specify
2284 service in request". It would seem that Dovecot has changed its
2285 interface. Fortunately there's a specification; I followed it and
2286 changed what the client sends and it appears to be working now.

2292 address A is aliased to B and C, where B exists and C does not. Without
2293 -v the output is "A verified" because verification stops after a
2294 successful redirection if more than one address is generated. However,
2295 with -v the child addresses are also verified. Exim was outputting "A
2296 failed to verify" and then showing the successful verification for C,
2297 with its parentage. It now outputs "B failed to verify", showing B's
2298 parentage before showing the successful verification of C.

322050c2
PH
2304PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2305 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2306 they consult the DNS. I had assumed they would set it the way they
2307 wanted; and indeed my experiments on Linux seem to show that in some
2308 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2309 To be on the safe side, however, I have now made the interface to
2310 host_find_byname() similar to host_find_bydns(), with an argument
2311 containing the DNS resolver options. The host_find_byname() function now
2312 sets these options at its start, just as host_find_bydns() does. The smtp
2313 transport options dns_qualify_single and dns_search_parents are passed to
2314 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2315 of host_find_byname() use the default settings of RES_DEFNAMES
2316 (qualify_single) but not RES_DNSRCH (search_parents).

2321 overdue, caused by the large number of possibilities that now exist.

2326PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2327 flag allowing group syntax was set by the header_syntax check but not
2328 turned off, possible causing trouble later; (2) The flag was not being
2329 set at all for the header_verify test, causing "group"-style headers to
2330 be rejected. I have now set it in this case, and also caused header_
2331 verify to ignore an empty address taken from a group. While doing this, I
2332 came across some other cases where the code for allowing group syntax
2333 while scanning a header line wasn't quite right (mostly, not resetting
2334 the flag correctly in the right place). These bugs could have caused
2335 trouble for malformed header lines. I hope it is now all correct.

2337PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

2339 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2340 but it didn't always do it. This confused somebody who was copying the
2341 code for some other use. I have removed all the tests.

2343PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2344 feature that was used to support insecure browsers during the U.S. crypto
2345 embargo. It requires special client support, and Exim is probably the
2346 only MTA that supported it -- and would never use it because real RSA is
2347 always available. This code has been removed, because it had the bad
2348 effect of slowing Exim down by computing (never used) parameters for the
2349 RSA_EXPORT functionality.

2354 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2355 if the connection is using TLS or if the remote IP is the same as the
2356 local IP, and the "valid-client-cert option" if a client certificate has
2357 been verified.

2388
2389PH/30 Exim was sometimes attempting to deliver messages that had suffered
2390 address errors (4xx response to RCPT) over the same connection as other
2391 messages routed to the same hosts. Such deliveries are always "forced",
2392 so retry times are not inspected. This resulted in far too many retries
2393 for the affected addresses. The effect occurred only when there were more
2394 hosts than the hosts_max_try setting in the smtp transport when it had
2395 the 4xx errors. Those hosts that it had tried were not added to the list
2396 of hosts for which the message was waiting, so if all were tried, there
2397 was no problem. Two fixes have been applied:
2398
2399 (i) If there are any address or message errors in an SMTP delivery, none
2400 of the hosts (tried or untried) are now added to the list of hosts
2401 for which the message is waiting, so the message should not be a
2402 candidate for sending over the same connection that was used for a
2403 successful delivery of some other message. This seems entirely
2404 reasonable: after all the message is NOT "waiting for some host".
2405 This is so "obvious" that I'm not sure why it wasn't done
2406 previously. Hope I haven't missed anything, but it can't do any
2407 harm, as the worst effect is to miss an optimization.
2408
2409 (ii) If, despite (i), such a delivery is accidentally attempted, the
2410 routing retry time is respected, so at least it doesn't keep
2411 hammering the server.

2426PH/35 The error "getsockname() failed: connection reset by peer" was being
2427 written to the panic log as well as the main log, but it isn't really
2428 panic-worthy as it just means the connection died rather early on. I have
2429 removed the panic log writing for the ECONNRESET error when getsockname()
2430 fails.
2431
48c7f9e2
PH
2432PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2433 runs only) independently of the message's sender address. This meant
2434 that, if the 4xx error was in fact related to the sender, a different
2435 message to the same recipient with a different sender could confuse
2436 things. In particualar, this can happen when sending to a greylisting
2437 server, but other circumstances could also provoke similar problems.
2438 I have changed the default so that the retry time for these errors is now
2439 based a combination of the sender and recipient addresses. This change
2440 can be overridden by setting address_retry_include_sender=false in the
2441 smtp transport.

2713 kind of temporary error. A kludge has been added to help with this.
2714 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2715 554 error is used if errno is still zero or contains ENOENT (which occurs
2716 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2717 451 error is used.

2753PH/01 The code for finding all the local interface addresses on a FreeBSD
2754 system running IPv6 was broken. This may well have applied to all BSD
2755 systems, as well as to others that have similar system calls. The broken
2756 code found IPv4 interfaces correctly, but gave incorrect values for the
2757 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2758 that it would not match correctly against @[] and not recognize the IPv6
2759 addresses as local.

2839 major problems that occur when a DNS server includes only records of one
2840 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2841 fixed another bug: if SRV records were looked up and the corresponding
2842 address records were *not* found in the additional section, the port
2843 values from the SRV records were lost.

PH
2853PH/19 When calculating a retry time, Exim used to measure the "time since
2854 failure" by looking at the "first failed" field in the retry record. Now
2855 it does not use this if it is later than than the arrival time of the
2856 message. Instead it uses the arrival time. This makes for better
2857 behaviour in cases where some deliveries succeed, thus re-setting the
2858 "first failed" field. An example is a quota failure for a huge message
2859 when small messages continue to be delivered. Without this change, the
2860 "time since failure" will always be short, possible causing more frequent
2861 delivery attempts for the huge message than are intended.

2958PH/42 The content-scanning code uses fopen() to create files in which to put
2959 message data. Previously it was not paying any attention to the mode of

2961 files with open(), and sets the required mode explicitly. Thus, these
2962 files were ending up world-writeable. This was not a big issue, because,
2963 being within the spool directory, they were not world-accessible. I have
2964 created a function called modefopen, which takes an additional mode
2965 argument. It sets umask(777), creates the file, chmods it to the required
2966 mode, then resets the umask. All the relevant calls to fopen() in the

3007 was used in LMTP mode. This meant that they could be retried too
3008 frequently, and not timed out correctly.
3009
3010 (ii) Exim was setting the flag that allows error details to be returned
3011 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3012 recipients that were returned after the DATA command.
3013
3014PH/53 This is related to PH/52, but is more general: for any failing address,
3015 when detailed error information was permitted to be returned to the

3088PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3089 function verify_get_ident() calls ip_connect() to connect a socket, but
3090 if the "connect()" function timed out, ip_connect() used to close the
3091 socket. However, verify_get_ident() also closes the socket later, and in
3092 between Exim writes to the log, which may get opened at this point. When
3093 the socket was closed in ip_connect(), the log could get the same file
3094 descriptor number as the socket. This naturally causes chaos. The fix is
3095 not to close the socket in ip_connect(); the socket should be closed by
3096 the function that creates it. There was only one place in the code where
3097 this was missing, in the iplookup router, which I don't think anybody now
3098 uses, but I've fixed it anyway.

3108PH/01 Two changes to the default runtime configuration:
3109
3110 (1) Move the checks for relay_from_hosts and authenticated clients from
3111 after to before the (commented out) DNS black list checks.
3112
3113 (2) Add control=submission to the relay_from_hosts and authenticated
3114 clients checks, on the grounds that messages accepted by these
3115 statements are most likely to be submissions.

PH
3117PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3118
3119 (1) Generate an error if the third argument for the ${prvs expansion is
3120 not a single digit.
3121
3122 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3123 string.
3124
3125 (3) Reset the variables that are obtained from the first argument of
3126 ${prvscheck and used in the second argument before leaving the code,
3127 because their memory is reclaimed, so using them afterwards may do
3128 silly things.
3129
3130 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3131 one (it's much easier than Tom thought :-).
3132
3133 (5) Because of (4), we can now allow for the use of $prvscheck_result
3134 inside the third argument.

3143PH/05 When a filter generated an autoreply, the entire To: header line was
3144 quoted in the delivery log line, like this:
3145
3146 => >A.N.Other <ano@some.domain> <original@ddress> ...
3147
3148 This has been changed so that it extracts the operative address. There
3149 may be more than one such address. If so, they are comma-separated, like
3150 this:
3151
3152 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3154PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3155 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3156 not being looked up in the rDNS to get a host name, Exim was showing the
3157 IP address twice in Received: lines, even though the IP addresses were
3158 identical. For example:
3159
3160 Received: from [1.2.3.4] (helo=[1.2.3.4])
3161
3162 However, if the real host name was known, it was omitting the HELO data
3163 if it matched the actual IP address. This has been tidied up so that it
3164 doesn't show the same IP address twice.

3166PH/07 When both +timestamp and +memory debugging was on, the value given by
3167 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3168 called by the debug printing, thereby overwriting the timestamp buffer.
3169 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3174 message.

PH
3190PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
3191 Electronic Mail") by including:
3192
3193 Auto-submitted: auto-generated
3194
3195 in the messages that it generates (bounce messages and others, such as
3196 warnings). In the case of bounce messages for non-SMTP mesages, there was
3197 also a typo: it was using "Auto_submitted" (underscore instead of
3198 hyphen). Since every message generated by Exim is necessarily in response
3199 to another message, thes have all been changed to:
3200
3201 Auto-Submitted: auto-replied
3202
3203 in accordance with these statements in the RFC:
3204
3205 The auto-replied keyword:
3206
3207 - SHOULD be used on messages sent in direct response to another
3208 message by an automatic process,
3209
3210 - MUST NOT be used on manually-generated messages,
3211
3212 - MAY be used on Delivery Status Notifications (DSNs) and Message
3213 Disposition Notifications (MDNs),
3214
3215 - MUST NOT be used on messages generated by automatic or periodic
3216 processes, except for messages which are automatic responses to
3217 other messages.

3238PH/17 A further patch from the Sieve maintainer: "Introduce the new Sieve
3239 extension "envelope-auth". The code is finished and in agreement with
3240 other implementations, but there is no documentation so far and in fact,
3241 nobody wrote the draft yet. This extension is currently #undef'ed, thus
3242 not changing the active code.
3243
3244 Print executed "if" and "elsif" statements when debugging is used. This
3245 helps a great deal to understand what a filter does.
3246
3247 Document more things not specified clearly in RFC3028. I had all this
3248 sorted out, when out of a sudden new issues came to my mind. Oops."

PH
3253PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
3254 canonical form (as documented). However, after a host name lookup from
3255 the IP address, check_host() was doing a simple string comparison with
3256 addresses acquired from the DNS when checking that the found name did
3257 have the original IP as one of its addresses. Since any found IPv6
3258 addresses are likely to be in abbreviated form, the comparison could
3259 fail. Luckily, there already exists a function for doing the comparison
3260 by converting both addresses to binary, so now that is used instead of
3261 the text comparison.
3262
96776534
PH
3263PH/20 There was another similar case to PH/19, when a complete host name was
3264 given in a host list; looking up its IP address could give an abbreviated
3265 form, whereas the current host's name might or might not be abbreviated.
3266 The same fix has been applied.
