9427e879 11JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
4c04137d 12 than -2003 did; needs libidn2 in addition to libidn.

19JH/03 Bug 2003: fix Proxy Protocol v2 handling: the address size field was
20 missing a wire-to-host endian conversion.
21

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.

27PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of
28 no_require_dnssec option and creation of _HAVE_TRANSPORT_APPEND_MAILDIR
29 macro. Patches provided by Josh Soref.

JH
31JH/05 Have the EHLO response advertise VRFY, if there is a vrfy ACL defined.
32 Previously we did not; the RFC seems ambiguous and VRFY is not listed
33 by IANA as a service extension. However, John Klensin suggests that we
34 should.
35
36JH/06 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
b895f4b2
JH
37 the dkim code may be unix-mode line endings rather than smtp wire-format
38 CRLF, so prepend a CR to any bare LF.
fd047340 39
bd8fbe36 40JH/07 Rationalise the coding for callout smtp conversations and transport ones.
902fbd69
JH
41 As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
42
bd8fbe36
JH
43JH/08 Bug 2016: Fix DKIM verification vs. CHUNKING. Any BDAT commands after
44 the first were themselves being wrongly included in the feed into dkim
45 processing; with most chunk sizes in use this resulted in an incorrect
46 body hash calculated value.
47
eea19017
JH
48JH/09 Bug 2014: permit inclusion of a DKIM-Signature header in a received
49 DKIM signature block, for verification. Although advised against by
50 standards it is specifically not ruled illegal.
51

JH
52JH/10 Bug 2025: Fix reception of (quoted) local-parts with embedded spaces.
53
54JH/11 Bug 2029: Fix crash in DKIM verification when a message signature block is
55 missing a body hash (the bh= tag).
56
57JH/12 Bug 2018: Re-order Proxy Protocol startup versus TLS-on-connect startup.
58 It seems that HAProxy sends the Proxy Protocol information in clear and
59 only then does a TLS startup, so do the same.
60
61JH/13 Bug 2027: Avoid attempting to use TCP Fast Open for non-transport client
62 TCP connections (such as for Spamd) unless the daemon successfully set
63 Fast Open mode on its listening sockets. This fixes breakage seen on
64 too-old kernels or those not configured for Fast Open, at the cost of
65 requiring both directions being enabled for TFO, and TFO never being used
66 by non-daemon-related Exim processes.
67
68JH/14 Bug 2000: Reject messages recieved with CHUNKING but with malformed line
69 endings, at least on the first header line. Try to canonify any that get
70 past that check, despite the cost.
71
b6040544
JH
72JH/15 Angle-bracket nesting (an error inserted by broken sendmails) levels are
73 now limited to an arbitrary five deep, while parsing addresses with the
74 strip_excess_angle_brackets option enabled.

77 instead leave the unprompted TLS handshake in socket buffer for the
78 TLS library to consume.

86-----------------
4c57a40e 87
9094b84b
JH
88JH/01 Use SIZE on MAIL FROM in a cutthrough connection, if the destination
89 supports it and a size is available (ie. the sending peer gave us one).
8d042305 90
03d5892b
JH
91JH/02 The obsolete acl condition "demime" is removed (finally, after ten
92 years of being deprecated). The replacements are the ACLs
93 acl_smtp_mime and acl_not_smtp_mime.
94
4b0fe319
JH
95JH/03 Upgrade security requirements imposed for hosts_try_dane: previously
96 a downgraded non-dane trust-anchor for the TLS connection (CA-style)
97 or even an in-clear connection were permitted. Now, if the host lookup
98 was dnssec and dane was requested then the host is only used if the
99 TLSA lookup succeeds and is dnssec. Further hosts (eg. lower priority
100 MXs) will be tried (for hosts_try_dane though not for hosts_require_dane)
101 if one fails this test.
102 This means that a poorly-configured remote DNS will make it incommunicado;
103 but it protects against a DNS-interception attack on it.
104

105JH/04 Bug 1810: make continued-use of an open smtp transport connection
106 non-noisy when a race steals the message being considered.

f59aaaaa 109 self-signed certificate for inbound TLS connections.

114JH/07 Retire gnutls_require_mac et.al. These were nonfunctional since 4.80
115 and logged a warning sing 4.83; now they are a configuration file error.

122JH/10 Support ${sha256:} applied to a string (as well as the previous
123 certificate).

98c82a3d
JH
125JH/11 Cutthrough: avoid using the callout hints db on a verify callout when
126 a cutthrough deliver is pending, as we always want to make a connection.
127 This also avoids re-routing the message when later placing the cutthrough
128 connection after a verify cache hit.
129 Do not update it with the verify result either.
130
131JH/12 Cutthrough: disable when verify option success_on_redirect is used, and
132 when routing results in more than one destination address.
133
ae8386f0
JH
134JH/13 Cutthrough: expand transport dkim_domain option when testing for dkim
135 signing (which inhibits the cutthrough capability). Previously only
136 the presence of an option was tested; now an expansion evaluating as
137 empty is permissible (obviously it should depend only on data available
138 when the cutthrough connection is made).
139
0d9fa8c0
JH
140JH/14 Fix logging of errors under PIPELINING. Previously the log line giving
141 the relevant preceding SMTP command did not note the pipelining mode.

144 Previously they were not counted.
145
ef3a1a30
JH
146JH/16 DANE: treat a TLSA lookup response having all non-TLSA RRs, the same
147 as one having no matching records. Previously we deferred the message
148 that needed the lookup.
149

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

JH
164JH/22 Fix continued use of a connection for further deliveries. If a port was
165 specified by a router, it must also match for the delivery to be
166 compatible.
167
e3b1f624
JH
168JH/23 Bug 1874: fix continued use of a connection for further deliveries.
169 When one of the recipients of a message was unsuitable for the connection
170 (has no matching addresses), we lost track of needing to mark it
171 deferred. As a result mail would be lost.

JH
173JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
174
f59aaaaa 175JH/25 Decoding ACL controls is now done using a binary search; the source code
2d009132
JH
176 takes up less space and should be simpler to maintain. Merge the ACL
177 condition decode tables also, with similar effect.

d1f9fb42
JH
179JH/26 Fix problem with one_time used on a redirect router which returned the
180 parent address unchanged. A retry would see the parent address marked as
181 delivered, so not attempt the (identical) child. As a result mail would
182 be lost.

184JH/27 Fix a possible security hole, wherein a process operating with the Exim
185 UID can gain a root shell. Credit to http://www.halfdog.net/ for

232JH/01 Bug 1664: Disable OCSP for GnuTLS library versions at/before 3.3.16
233 and 3.4.4 - once the server is enabled to respond to an OCSP request
234 it does even when not requested, resulting in a stapling non-aware
235 client dropping the TLS connection.

240TF/02 Improve the consistency of logging incoming and outgoing interfaces.
241 The I= interface field on outgoing lines is now after the H= remote

243 outgoing_interface log selector which allows you to disable the
244 outgoing I= field.

JH
246JH/02 Bug 728: Close logfiles after a daemon-process "exceptional" log write.
247 If not running log_selector +smtp_connection the mainlog would be held
248 open indefinitely after a "too many connections" event, including to a
249 deleted file after a log rotate. Leave the per net connection logging
250 leaving it open for efficiency as that will be quickly detected by the
251 check on the next write.

253HS/01 Bug 1671: Fix post transport crash.
254 Processing the wait-<transport> messages could crash the delivery
255 process if the message IDs didn't exist for some reason. When
256 using 'split_spool_directory=yes' the construction of the spool
257 file name failed already, exposing the same netto behaviour.

JH
266JH/05 Downgrade message for a TLS-certificate-based authentication fail from

4c04137d 308 with TLS, default unset, mainly to enable keeping the testsuite sane.
23f3dc67

309 If a server certificate is not supplied (via tls_certificate) an error is

318JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
319 in transport context, after the attempt, and per-recipient. The latter type
320 is per host attempted. The event data is the error message, and the errno
321 information encodes the lookup type (A vs. MX) used for the (first) host,
4c04137d 322 and the trailing two digits of the smtp 4xx response.

62ac2eb7 387 Commonly the sender saw a TCP-level error, and retransmitted the message
1bc460a6

917TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
918
919 When a queue runner is handling a message, Exim first routes the
920 recipient addresses, during which it prunes them based on the retry
921 hints database. After that it attempts to deliver the message to
922 any remaining recipients. It then updates the hints database using
923 the retry rules.
924
925 So if a recipient address works intermittently, it can get repeatedly
926 deferred at routing time. The retry hints record remains fresh so the
927 address never reaches the final cutoff time.
928
929 This is a fairly common occurrence when a user is bumping up against
930 their storage quota. Exim had some logic in its local delivery code
931 to deal with this. However it did not apply to per-recipient defers
932 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
933
1ddeb334
TF
934 This change adds a proper retry rule check during routing so that the
935 final cutoff time is checked against the message's age. We only do
936 this check if there is an address retry record and there is not a
937 domain retry record; this implies that previous attempts to handle
938 the address had the retry_use_local_parts option turned on. We use
939 this as an approximation for the destination being like a local
940 delivery, as in LMTP.
67bd1ab3
TF
941
942 I suspect this new check makes the old local delivery cutoff check
943 redundant, but I have not verified this so I left the code in place.

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

1265TF/03 Make the exiwhat support code safe for signals. Previously Exim might
1266 lock up or crash if it happened to be inside a call to libc when it
1267 got a SIGUSR1 from exiwhat.
1268
1269 The SIGUSR1 handler appends the current process status to the process
1270 log which is later printed by exiwhat. It used to use the general
1271 purpose logging code to do this, but several functions it calls are
1272 not safe for signals.
1273
1274 The new output code in the SIGUSR1 handler is specific to the process
1275 log, and simple enough that it's easy to inspect for signal safety.
1276 Removing some special cases also simplifies the general logging code.
1277 Removing the spurious timestamps from the process log simplifies
1278 exiwhat.
1279
c99ce5c9
TF
1280TF/04 Improved ratelimit ACL condition.
1281
1282 The /noupdate option has been deprecated in favour of /readonly which
1283 has clearer semantics. The /leaky, /strict, and /readonly update modes
1284 are mutually exclusive. The update mode is no longer included in the
1285 database key; it just determines when the database is updated. (This
4c04137d 1286 means that when you upgrade Exim will forget old rate measurements.)
c99ce5c9
TF
1287
1288 Exim now checks that the per_* options are used with an update mode that
1289 makes sense for the current ACL. For example, when Exim is processing a
1290 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
1291 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
1292 must specify per_mail/readonly. If you omit the update mode it defaults to
1293 /leaky where that makes sense (as before) or /readonly where required.
1294
1295 The /noupdate option is now undocumented but still supported for
1296 backwards compatibility. It is equivalent to /readonly except that in
1297 ACLs where /readonly is required you may specify /leaky/noupdate or
1298 /strict/noupdate which are treated the same as /readonly.
1299
1300 A useful new feature is the /count= option. This is a generalization
1301 of the per_byte option, so that you can measure the throughput of other
1302 aggregate values. For example, the per_byte option is now equivalent
1303 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
1304
1305 The per_rcpt option has been generalized using the /count= mechanism
1306 (though it's more complicated than the per_byte equivalence). When it is
1307 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
1308 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
1309 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
1310 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
1311 Note that using per_rcpt with a non-readonly update mode in more than
1312 one ACL will cause the recipients to be double-counted. (The per_mail
1313 and per_byte options don't have this problem.)
1314
1315 The handling of very low rates has changed slightly. If the computed rate
1316 is less than the event's count (usually one) then this event is the first
1317 after a long gap. In this case the rate is set to the same as this event's
1318 count, so that the first message of a spam run is counted properly.
1319
1320 The major new feature is a mechanism for counting the rate of unique
1321 events. The new per_addr option counts the number of different
1322 recipients that someone has sent messages to in the last time period. It
1323 behaves like per_rcpt if all the recipient addresses are different, but
1324 duplicate recipient addresses do not increase the measured rate. Like
1325 the /count= option this is a general mechanism, so the per_addr option
1326 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
1327 example, measure the rate that a client uses different sender addresses
1328 with the options per_mail/unique=$sender_address. There are further
1329 details in the main documentation.

1900
1901PH/01 Another patch from the Sieve maintainer.
1902
6a3bceb1
PH
1903PH/02 When an IPv6 address is converted to a string for single-key lookup
1904 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1905 dots are used instead of colons so that keys in lsearch files need not
1906 contain colons. This was done some time before quoting was made available
1907 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1908 (notated using the quote facility) so as to distinguish them from IPv4
1909 keys. This meant that lookups for IP addresses in host lists did not work
1910 for iplsearch lookups.
1911
1912 This has been fixed by arranging for IPv6 addresses to be expressed with
1913 colons if the lookup type is iplsearch. This is not incompatible, because
1914 previously such lookups could never work.
1915
4c04137d 1916 The situation is now rather anomalous, since one *can* have colons in
6a3bceb1
PH
1917 ordinary lsearch keys. However, making the change in all cases is
1918 incompatible and would probably break a number of configurations.

MH
1923MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1924 conversion specification without a maximum field width, thereby enabling
1925 a rogue spamd server to cause a buffer overflow. While nobody in their

2124 some time before the response is written. In this time, more input might
2125 arrive, invalidly. So now there are extra checks after an ACL has run for
2126 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
2127 pipelining has not been advertised.

2201 the response to the final '.' that terminates a message, but only in the
2202 case where the client has not sent further data following the '.'
2203 (unfortunately, this is allowed). However, in many cases there won't be
2204 any further data because there won't be any more messages to send. A call
2205 to select() can be used: if it shows that the input is "ready", there is
2206 either input waiting, or the socket has been closed. An attempt to read
2207 the next input character can distinguish the two cases. Previously, Exim
58eb016e 2208 would have sent an OK response which the client would never have see.

2219PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
2220 fixed by 4.65/MH/01 (is this a record?) are fixed:
2221
2222 (i) An empty string was always treated as zero by the numeric comparison
2223 operators. This behaviour has been restored.
2224
2225 (ii) It is documented that the numeric comparison operators always treat
2226 their arguments as decimal numbers. This was broken in that numbers
2227 starting with 0 were being interpreted as octal.
2228
2229 While fixing these problems I realized that there was another issue that
2230 hadn't been noticed. Values of message_size_limit (both the global option
2231 and the transport option) were treated as octal if they started with 0.
2232 The documentation was vague. These values are now always treated as
2233 decimal, and I will make that clear in the documentation.

PH
2277PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
2278 callout verification, Exim cached a "reject" for the entire domain. This
2279 is correct for most verifications, but it is not correct for a recipient
2280 verification with use_sender or use_postmaster set, because in that case
2281 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
2282 case of MAIL FROM:<> rejection from other early rejections (e.g.
2283 rejection of HELO). When verifying a recipient using a non-null MAIL
2284 address, the cache is ignored if it shows MAIL FROM:<> rejection.
2285 Whatever the result of the callout, the value of the domain cache is
2286 left unchanged (for any other kind of callout, getting as far as trying
2287 RCPT means that the domain itself is ok).

2321PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
2322 hostname. This is wrong, because it relates to the incoming message (and
2323 probably the interface on which it is arriving) and not to the outgoing
2324 callout (which could be using a different interface). This has been
2325 changed to use the value of the helo_data option from the smtp transport
2326 instead - this is what is used when a message is actually being sent. If
2327 there is no remote transport (possible with a router that sets up host
2328 addresses), $smtp_active_hostname is used.

14aa5a05 2330PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 2331 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
2332 (a) The code assumed that strncpy() returns a negative number on buffer
2333 overflow, which isn't the case. Replaced with Exim's string_format()
2334 function.
2335 (b) There were several signed/unsigned issues. I just did the minimum
2336 hacking in of casts. There is scope for a larger refactoring.
2337 (c) The code used strcasecmp() which is not a standard C function.
2338 Replaced with Exim's strcmpic() function.
2339 (d) The code set only $1; it now sets $auth1 as well.
2340 (e) A simple test gave the error "authentication client didn't specify
2341 service in request". It would seem that Dovecot has changed its
2342 interface. Fortunately there's a specification; I followed it and
2343 changed what the client sends and it appears to be working now.

PH
2348PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
2349 address A is aliased to B and C, where B exists and C does not. Without
2350 -v the output is "A verified" because verification stops after a
2351 successful redirection if more than one address is generated. However,
2352 with -v the child addresses are also verified. Exim was outputting "A
2353 failed to verify" and then showing the successful verification for C,
2354 with its parentage. It now outputs "B failed to verify", showing B's
2355 parentage before showing the successful verification of C.

PH
2357PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
2358 look up a TXT record in a specific list after matching in a combined
2359 list.
2360
322050c2
PH
2361PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
2362 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
2363 they consult the DNS. I had assumed they would set it the way they
2364 wanted; and indeed my experiments on Linux seem to show that in some
2365 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
2366 To be on the safe side, however, I have now made the interface to
2367 host_find_byname() similar to host_find_bydns(), with an argument
2368 containing the DNS resolver options. The host_find_byname() function now
2369 sets these options at its start, just as host_find_bydns() does. The smtp
2370 transport options dns_qualify_single and dns_search_parents are passed to
2371 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
2372 of host_find_byname() use the default settings of RES_DEFNAMES
2373 (qualify_single) but not RES_DNSRCH (search_parents).
2374
08955dd3
PH
2375PH/17 Applied (a modified version of) Nico Erfurth's patch to make
2376 spool_read_header() do less string testing, by means of a preliminary
2377 switch on the second character of optional "-foo" lines. (This is
2378 overdue, caused by the large number of possibilities that now exist.
2379 Originally there were few.) While I was there, I also converted the
2380 str(n)cmp tests so they don't re-test the leading "-" and the first
2381 character, in the hope this might squeeze out yet more improvement.
2382

PH
2383PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
2384 flag allowing group syntax was set by the header_syntax check but not
2385 turned off, possible causing trouble later; (2) The flag was not being
2386 set at all for the header_verify test, causing "group"-style headers to
2387 be rejected. I have now set it in this case, and also caused header_
2388 verify to ignore an empty address taken from a group. While doing this, I
2389 came across some other cases where the code for allowing group syntax
2390 while scanning a header line wasn't quite right (mostly, not resetting
2391 the flag correctly in the right place). These bugs could have caused
2392 trouble for malformed header lines. I hope it is now all correct.
2393
602e59e5
PH
2394PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
2395 with the "reply" argument non-NULL. The code, however (which originally
2396 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
2397 but it didn't always do it. This confused somebody who was copying the
2398 code for some other use. I have removed all the tests.

411ef850
PH
2400PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
2401 feature that was used to support insecure browsers during the U.S. crypto
2402 embargo. It requires special client support, and Exim is probably the
2403 only MTA that supported it -- and would never use it because real RSA is
2404 always available. This code has been removed, because it had the bad
2405 effect of slowing Exim down by computing (never used) parameters for the
2406 RSA_EXPORT functionality.
2407
7befa435
PH
2408PH/21 On the advice of Timo Sirainen, added a check to the dovecot
2409 authenticator to fail if there's a tab character in the incoming data
2410 (there should never be unless someone is messing about, as it's supposed
2411 to be base64-encoded). Also added, on Timo's advice, the "secured" option
2412 if the connection is using TLS or if the remote IP is the same as the
2413 local IP, and the "valid-client-cert option" if a client certificate has
2414 been verified.
2415
48da4259 2416PH/22 As suggested by Dennis Davis, added a server_condition option to *all*

PH
2445
2446PH/30 Exim was sometimes attempting to deliver messages that had suffered
2447 address errors (4xx response to RCPT) over the same connection as other
2448 messages routed to the same hosts. Such deliveries are always "forced",
2449 so retry times are not inspected. This resulted in far too many retries
2450 for the affected addresses. The effect occurred only when there were more
2451 hosts than the hosts_max_try setting in the smtp transport when it had
2452 the 4xx errors. Those hosts that it had tried were not added to the list
2453 of hosts for which the message was waiting, so if all were tried, there
2454 was no problem. Two fixes have been applied:
2455
2456 (i) If there are any address or message errors in an SMTP delivery, none
2457 of the hosts (tried or untried) are now added to the list of hosts
2458 for which the message is waiting, so the message should not be a
2459 candidate for sending over the same connection that was used for a
2460 successful delivery of some other message. This seems entirely
2461 reasonable: after all the message is NOT "waiting for some host".
2462 This is so "obvious" that I'm not sure why it wasn't done
2463 previously. Hope I haven't missed anything, but it can't do any
2464 harm, as the worst effect is to miss an optimization.
2465
2466 (ii) If, despite (i), such a delivery is accidentally attempted, the
2467 routing retry time is respected, so at least it doesn't keep
2468 hammering the server.

2483PH/35 The error "getsockname() failed: connection reset by peer" was being
2484 written to the panic log as well as the main log, but it isn't really
2485 panic-worthy as it just means the connection died rather early on. I have
2486 removed the panic log writing for the ECONNRESET error when getsockname()
2487 fails.
2488
48c7f9e2
PH
2489PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2490 runs only) independently of the message's sender address. This meant
2491 that, if the 4xx error was in fact related to the sender, a different
2492 message to the same recipient with a different sender could confuse
4c04137d 2493 things. In particular, this can happen when sending to a greylisting
48c7f9e2
PH
2494 server, but other circumstances could also provoke similar problems.
2495 I have changed the default so that the retry time for these errors is now
2496 based a combination of the sender and recipient addresses. This change
2497 can be overridden by setting address_retry_include_sender=false in the
2498 smtp transport.

2766PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2768 Unfortunately, if there is a major crisis, such as a disk failure,
2769 tcp-wrappers gives "deny", whereas what one would like would be some
2770 kind of temporary error. A kludge has been added to help with this.
2771 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2772 554 error is used if errno is still zero or contains ENOENT (which occurs
2773 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2774 451 error is used.

2810PH/01 The code for finding all the local interface addresses on a FreeBSD
2811 system running IPv6 was broken. This may well have applied to all BSD
2812 systems, as well as to others that have similar system calls. The broken
2813 code found IPv4 interfaces correctly, but gave incorrect values for the
2814 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2815 that it would not match correctly against @[] and not recognize the IPv6
2816 addresses as local.

2859 autoreply, Exim could try to deliver to a non-existent relative file

2895 Instead, it always explicitly searches for A/AAAA records. This avoids
2896 major problems that occur when a DNS server includes only records of one
2897 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2898 fixed another bug: if SRV records were looked up and the corresponding
2899 address records were *not* found in the additional section, the port
2900 values from the SRV records were lost.

2910PH/19 When calculating a retry time, Exim used to measure the "time since
2911 failure" by looking at the "first failed" field in the retry record. Now
2912 it does not use this if it is later than than the arrival time of the
2913 message. Instead it uses the arrival time. This makes for better
2914 behaviour in cases where some deliveries succeed, thus re-setting the
2915 "first failed" field. An example is a quota failure for a huge message
2916 when small messages continue to be delivered. Without this change, the
2917 "time since failure" will always be short, possible causing more frequent
2918 delivery attempts for the huge message than are intended.

3015PH/42 The content-scanning code uses fopen() to create files in which to put
3016 message data. Previously it was not paying any attention to the mode of
3017 the files. Exim runs with umask(0) because the rest of the code creates
3018 files with open(), and sets the required mode explicitly. Thus, these
3019 files were ending up world-writeable. This was not a big issue, because,
3020 being within the spool directory, they were not world-accessible. I have
3021 created a function called modefopen, which takes an additional mode
3022 argument. It sets umask(777), creates the file, chmods it to the required
3023 mode, then resets the umask. All the relevant calls to fopen() in the

3064 was used in LMTP mode. This meant that they could be retried too
3065 frequently, and not timed out correctly.
3066
3067 (ii) Exim was setting the flag that allows error details to be returned
3068 for LMTP errors on RCPT commands, but not for LMTP errors for individual
3069 recipients that were returned after the DATA command.
3070
3071PH/53 This is related to PH/52, but is more general: for any failing address,
3072 when detailed error information was permitted to be returned to the

3113PH/62 When verifying, if an address was redirected to one new address, so that
3114 verification continued, and the new address failed or deferred after
3115 having set something in $address_data, the value of $address_data was not
3116 passed back to the ACL. This was different to the case when no
3117 redirection occurred. The value is now passed back in both cases.

3131PH/68 The bounce_return_message and bounce_return_body options were not being
3132 honoured for bounces generated during the reception of non-SMTP messages.
3133 In particular, this applied to messages rejected by the ACL. This bug has
3134 been fixed. However, if bounce_return_message is true and bounce_return_
3135 body is false, the headers that are returned for a non-SMTP message
3136 include only those that have been read before the error was detected.
3137 (In the case of an ACL rejection, they have all been read.)

3139PH/69 The HTML version of the specification is now built in a directory called

PH
3145PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
3146 function verify_get_ident() calls ip_connect() to connect a socket, but
3147 if the "connect()" function timed out, ip_connect() used to close the
3148 socket. However, verify_get_ident() also closes the socket later, and in
3149 between Exim writes to the log, which may get opened at this point. When
3150 the socket was closed in ip_connect(), the log could get the same file
3151 descriptor number as the socket. This naturally causes chaos. The fix is
3152 not to close the socket in ip_connect(); the socket should be closed by
3153 the function that creates it. There was only one place in the code where
3154 this was missing, in the iplookup router, which I don't think anybody now
3155 uses, but I've fixed it anyway.

3169
3170 (2) Add control=submission to the relay_from_hosts and authenticated
3171 clients checks, on the grounds that messages accepted by these
3172 statements are most likely to be submissions.

PH
3174PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
3175
3176 (1) Generate an error if the third argument for the ${prvs expansion is
3177 not a single digit.
3178
3179 (2) Treat a missing third argument of ${prvscheck as if it were an empty
3180 string.
3181
3182 (3) Reset the variables that are obtained from the first argument of
3183 ${prvscheck and used in the second argument before leaving the code,
3184 because their memory is reclaimed, so using them afterwards may do
3185 silly things.
3186
3187 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
3188 one (it's much easier than Tom thought :-).
3189
3190 (5) Because of (4), we can now allow for the use of $prvscheck_result
3191 inside the third argument.

PH
3200PH/05 When a filter generated an autoreply, the entire To: header line was
3201 quoted in the delivery log line, like this:
3202
3203 => >A.N.Other <ano@some.domain> <original@ddress> ...
3204
3205 This has been changed so that it extracts the operative address. There
3206 may be more than one such address. If so, they are comma-separated, like
3207 this:
3208
3209 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
3211PH/06 When a client host used a correct literal IP address in a HELO or EHLO
3212 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
3213 not being looked up in the rDNS to get a host name, Exim was showing the
3214 IP address twice in Received: lines, even though the IP addresses were
3215 identical. For example:
3216
3217 Received: from [1.2.3.4] (helo=[1.2.3.4])
3218
3219 However, if the real host name was known, it was omitting the HELO data
3220 if it matched the actual IP address. This has been tidied up so that it
3221 doesn't show the same IP address twice.

3223PH/07 When both +timestamp and +memory debugging was on, the value given by
3224 $tod_xxx expansions could be wrong, because the tod_stamp() function was
3225 called by the debug printing, thereby overwriting the timestamp buffer.
3226 Debugging no longer uses the tod_stamp() function when +timestamp is set.

3247PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

3249
3250 Auto-submitted: auto-generated
3251
3252 in the messages that it generates (bounce messages and others, such as
4c04137d 3253 warnings). In the case of bounce messages for non-SMTP messages, there was
456682f5
PH
3254 also a typo: it was using "Auto_submitted" (underscore instead of
3255 hyphen). Since every message generated by Exim is necessarily in response
3256 to another message, thes have all been changed to:
3257
3258 Auto-Submitted: auto-replied
3259
3260 in accordance with these statements in the RFC:
3261
3262 The auto-replied keyword:
3263
3264 - SHOULD be used on messages sent in direct response to another
3265 message by an automatic process,
3266
3267 - MUST NOT be used on manually-generated messages,
3268
3269 - MAY be used on Delivery Status Notifications (DSNs) and Message
3270 Disposition Notifications (MDNs),
3271
3272 - MUST NOT be used on messages generated by automatic or periodic
3273 processes, except for messages which are automatic responses to
3274 other messages.
