6-----------------
7
8TF/01 Correctly close the server side of TLS when forking for delivery.
9
10 When a message was received over SMTP with TLS, Exim failed to clear up
11 the incoming connection properly after forking off the child process to
12 deliver the message. In some situations the subsequent outgoing
13 delivery connection happened to have the same fd number as the incoming
14 connection previously had. Exim would try to use TLS and fail, logging
15 a "Bad file descriptor" error.

245TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
246
247 When a queue runner is handling a message, Exim first routes the
248 recipient addresses, during which it prunes them based on the retry
249 hints database. After that it attempts to deliver the message to
250 any remaining recipients. It then updates the hints database using
251 the retry rules.
252
253 So if a recipient address works intermittently, it can get repeatedly
254 deferred at routing time. The retry hints record remains fresh so the
255 address never reaches the final cutoff time.
256
257 This is a fairly common occurrence when a user is bumping up against
258 their storage quota. Exim had some logic in its local delivery code
259 to deal with this. However it did not apply to per-recipient defers
260 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
261
1ddeb334
TF
262 This change adds a proper retry rule check during routing so that the
263 final cutoff time is checked against the message's age. We only do
264 this check if there is an address retry record and there is not a
265 domain retry record; this implies that previous attempts to handle
266 the address had the retry_use_local_parts option turned on. We use
267 this as an approximation for the destination being like a local
268 delivery, as in LMTP.
67bd1ab3
TF
269
270 I suspect this new check makes the old local delivery cutoff check
271 redundant, but I have not verified this so I left the code in place.

274
275 Test 0254 submits a message to Exim with the header
276
277 Resent-From: f
278
279 When I ran the test suite under the user fanf2, Exim expanded
280 the header to contain my full name, whereas it should have added
281 a Resent-Sender: header. It erroneously treats any prefix of the
282 username as equal to the username.
283
284 This change corrects that bug.

305JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
306 Server implementation by Todd Lyons, client by JH.
307 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
308 config variable "prdr_enable" controls whether the server
309 advertises the facility. If the client requests PRDR a new
310 acl_data_smtp_prdr ACL is called once for each recipient, after
311 the body content is received and before the acl_smtp_data ACL.
312 The client is controlled by bolth of: a hosts_try_prdr option
313 on the smtp transport, and the server advertisement.
314 Default client logging of deliveries and rejections involving
315 PRDR are flagged with the string "PRDR".

593TF/03 Make the exiwhat support code safe for signals. Previously Exim might
594 lock up or crash if it happened to be inside a call to libc when it
595 got a SIGUSR1 from exiwhat.
596
597 The SIGUSR1 handler appends the current process status to the process
598 log which is later printed by exiwhat. It used to use the general
599 purpose logging code to do this, but several functions it calls are
600 not safe for signals.
601
602 The new output code in the SIGUSR1 handler is specific to the process
603 log, and simple enough that it's easy to inspect for signal safety.
604 Removing some special cases also simplifies the general logging code.
605 Removing the spurious timestamps from the process log simplifies
606 exiwhat.
607
c99ce5c9
TF
608TF/04 Improved ratelimit ACL condition.
609
610 The /noupdate option has been deprecated in favour of /readonly which
611 has clearer semantics. The /leaky, /strict, and /readonly update modes
612 are mutually exclusive. The update mode is no longer included in the
613 database key; it just determines when the database is updated. (This
614 means that when you upgrde Exim will forget old rate measurements.)
615
616 Exim now checks that the per_* options are used with an update mode that
617 makes sense for the current ACL. For example, when Exim is processing a
618 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
619 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
620 must specify per_mail/readonly. If you omit the update mode it defaults to
621 /leaky where that makes sense (as before) or /readonly where required.
622
623 The /noupdate option is now undocumented but still supported for
624 backwards compatibility. It is equivalent to /readonly except that in
625 ACLs where /readonly is required you may specify /leaky/noupdate or
626 /strict/noupdate which are treated the same as /readonly.
627
628 A useful new feature is the /count= option. This is a generalization
629 of the per_byte option, so that you can measure the throughput of other
630 aggregate values. For example, the per_byte option is now equivalent
631 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
632
633 The per_rcpt option has been generalized using the /count= mechanism
634 (though it's more complicated than the per_byte equivalence). When it is
635 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
636 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
637 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
638 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
639 Note that using per_rcpt with a non-readonly update mode in more than
640 one ACL will cause the recipients to be double-counted. (The per_mail
641 and per_byte options don't have this problem.)
642
643 The handling of very low rates has changed slightly. If the computed rate
644 is less than the event's count (usually one) then this event is the first
645 after a long gap. In this case the rate is set to the same as this event's
646 count, so that the first message of a spam run is counted properly.
647
648 The major new feature is a mechanism for counting the rate of unique
649 events. The new per_addr option counts the number of different
650 recipients that someone has sent messages to in the last time period. It
651 behaves like per_rcpt if all the recipient addresses are different, but
652 duplicate recipient addresses do not increase the measured rate. Like
653 the /count= option this is a general mechanism, so the per_addr option
654 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
655 example, measure the rate that a client uses different sender addresses
656 with the options per_mail/unique=$sender_address. There are further
657 details in the main documentation.

1203TK/01 Add preliminary DKIM support. Currently requires a forked version of
1204 ALT-N's libdkim that I have put here:
1205 http://duncanthrax.net/exim-experimental/
1206
1207 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1208 were called 'true' and it seems that C99 defines that as a reserved
1209 keyword to be used with 'bool' variable types. That means you could
1210 not include C99-style headers which use bools without triggering
1211 build errors in sieve.c.

1227-----------------
1228
1229PH/01 Another patch from the Sieve maintainer.
1230
6a3bceb1
PH
1231PH/02 When an IPv6 address is converted to a string for single-key lookup
1232 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1233 dots are used instead of colons so that keys in lsearch files need not
1234 contain colons. This was done some time before quoting was made available
1235 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1236 (notated using the quote facility) so as to distinguish them from IPv4
1237 keys. This meant that lookups for IP addresses in host lists did not work
1238 for iplsearch lookups.
1239
1240 This has been fixed by arranging for IPv6 addresses to be expressed with
1241 colons if the lookup type is iplsearch. This is not incompatible, because
1242 previously such lookups could never work.
1243
1244 The situation is now rather anomolous, since one *can* have colons in
1245 ordinary lsearch keys. However, making the change in all cases is
1246 incompatible and would probably break a number of configurations.
1247
2e30fa9d
TK
1248TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
1249 version.
1250
0806a9c5
MH
1251MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1252 conversion specification without a maximum field width, thereby enabling
1253 a rogue spamd server to cause a buffer overflow. While nobody in their
1254 right mind would setup Exim to query an untrusted spamd server, an
1255 attacker that gains access to a server running spamd could potentially
1256 exploit this vulnerability to run arbitrary code as the Exim user.

TK
1258TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
1259 $primary_hostname instead of what libspf2 thinks the hosts name is.
1260
0f2cbd1b
MH
1261MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1262 a directory entry by the name of the lookup key. Previously, if a
1263 symlink pointed to a non-existing file or a file in a directory that
1264 Exim lacked permissions to read, a lookup for a key matching that
1265 symlink would fail. Now it is enough that a matching directory entry
1266 exists, symlink or not. (Bugzilla 503.)
1267
2b85bce7
PH
1268PH/03 The body_linecount and body_zerocount variables are now exported in the
1269 local_scan API.

1271PH/04 Added the $dnslist_matched variable.
1272
6c512171
PH
1273PH/05 Unset $tls_cipher and $tls_peerdn before making a connection as a client.
1274 This means they are set thereafter only if the connection becomes
1275 encrypted.
1276
1277PH/06 Added the client_condition to authenticators so that some can be skipped
1278 by clients under certain conditions.
1279
aa6dc513
PH
1280PH/07 The error message for a badly-placed control=no_multiline_responses left
1281 "_responses" off the end of the name.

1285PH/09 Tidied the code for creating ratelimiting keys, creating them explicitly
1286 (without spaces) instead of just copying the configuration text.

1295 way in which PCRE > 7.0 is built.

a4dc33a8
PH
1299PH/15 Removed an incorrect (int) cast when reading the value of SIZE in a
1300 MAIL command. The effect was to mangle the value on 64-bit systems.

1305
8932dffe
PH
1306PH/18 If a system quota error occurred while trying to create the file for
1307 a maildir delivery, the message "Mailbox is full" was not appended to the
1308 bounce if the delivery eventually timed out. Change 4.67/27 below applied
1309 only to a quota excession during the actual writing of the file.
d6a60c0f 1310
ddea74fa 1311PH/19 It seems that peer DN values may contain newlines (and other non-printing
48ed62d9
PH
1312 characters?) which causes problems in log lines. The DN values are now
1313 passed through string_printing() before being added to log lines.
1314
ddea74fa 1315PH/20 Added the "servers=" facility to MySQL and PostgreSQL lookups. (Oracle
b7670459
PH

MH
1332MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
1333 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
1334 Jan Srzednicki.
1335
b4ed4da0
PH
1336PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
1337 issue a MAIL command.
1338
431b7361
PH
1339PH/02 In an ACL statement such as
1340
1341 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1342
1343 if a client was not listed at all, or was listed with a value other than
1344 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1345 the condition was not true (as it should be), so access was not denied.
1346 The bug was that the ! inversion was incorrectly passed on to the second
1347 item. This has been fixed.
1348
1349PH/03 Added additional dnslists conditions == and =& which are different from
1350 = and & when the dns lookup returns more than one IP address.
1351
83da1223
PH
1352PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
1353 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
1354
54fc8428
PH
1355PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
1356 FSYNC, which compiles an option called disable_fsync that allows for
1357 bypassing fsync(). The documentation is heavily laced with warnings.
1358
34c5e8dd

PH
1361PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
1362 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
1363 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
1364 including adding "make clean"; (3) Added -fPIC when compiling the test
1365 dynamically loaded module, to get rid of a warning.
1366
0e8a9471
MH
1367MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
1368 message fails, move_frozen_messages = true and ignore_bounce_errors_after
1369 = 0s. The bug is otherwise harmless.
1370
f0872424
PH
1371PH/07 There was a bug in the dovecot authenticator such that the value of
1372 $auth1 could be overwritten, and so not correctly preserved, after a
1373 successful authentication. This usually meant that the value preserved by
1374 the server_setid option was incorrect.
1375
b01dd148
PH
1376PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.

6bf342e1
PH
1378PH/09 Installed PCRE release 7.0.
1379
273f34d0
PH
1380PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1381 run for batched SMTP input. It is now run at the start of every message
1382 in the batch. While fixing this I discovered that the process information
1383 (output by running exiwhat) was not always getting set for -bs and -bS
1384 input. This is fixed, and it now also says "batched" for BSMTP.
1385
cf8b11a5

1386PH/11 Added control=no_pipelining.
1387
41c7c167

1388PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
1389 patch, slightly modified), and move the expansion of helo_data till after
1390 the connection is made in the smtp transport (so it can use these
1391 values).

09945f1e
PH
1406PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
1407 was true (the default) a successful delivery failed to delete the retry
1408 item, thus causing premature timeout of the address. The bug is now
1409 fixed.
1410
c51b8e75
PH
1411PH/20 Added hosts_avoid_pipelining to the smtp transport.
1412
e28326d8
PH
1413PH/21 Long custom messages for fakedefer and fakereject are now split up
1414 into multiline reponses in the same way that messages for "deny" and
1415 other ACL rejections are.

PH
1423PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
1424 for deliveries of the second and subsequent messages over the same SMTP
1425 connection.

1428 ${reduce, with only minor "tidies".

SC
1430SC/02 Applied Daniel Tiefnig's patch to improve the '($parent) =' pattern match.
1431
c3611384
PH
1432PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
1433 expansion side effects.
1434
5a11a7b4
PH
1435PH/27 When a message times out after an over-quota error from an Exim-imposed
1436 quota, the bounce message says "mailbox is full". This message was not
1437 being given when it was a system quota that was exceeded. It now should
1438 be the same.
1439
0e20aff9
MH
1440MH/03 Made $recipients available in local_scan(). local_scan() already has
1441 better access to the recipient list through recipients_list[], but
1442 $recipients can be useful in postmaster-provided expansion strings.
1443
ca86f471
PH
1444PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1445 in the case of a MAIL command with additional options following the
1446 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1447 were accidentally chopped off.
1448
a14e5636
PH
1449PH/29 SMTP synchronization checks are implemented when a command is read -
1450 there is a check that no more input is waiting when there shouldn't be
1451 any. However, for some commands, a delay in an ACL can mean that it is
1452 some time before the response is written. In this time, more input might
1453 arrive, invalidly. So now there are extra checks after an ACL has run for
1454 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1455 pipelining has not been advertised.
1456
ec95d1a6
PH
1457PH/30 MH's patch to allow iscntrl() characters to be list separators.
1458
42855d71
PH
1459PH/31 Unlike :fail:, a custom message specified with :defer: was not being
1460 returned in the SMTP response when smtp_return_error_details was false.
1461 This has been fixed.
1462
57c2c631
PH
1463PH/32 Change the Dovecot authenticator to use read() and write() on the socket
1464 instead of the C I/O that was originally supplied, because problems were
1465 reported on Solaris.
1466
58c01c94
PH
1467PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1468 Exim which did not show up earlier: it was assuming that a call to
1469 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1470 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1471 was a macro that became an assignment, so it seemed to work. This has
1472 changed to a proper function call with a void return, hence the compile
1473 error. Exim's code has been fixed.
1474
dee5a20a
PH
1475PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
1476 cpus.

PH
1478PH/35 Applied a patch from the Sieve maintainer which fixes a bug in "notify".

b2d5182b
PH
1480PH/36 Applied John Jetmore's patch to add -v functionality to exigrep.
1481
79749a79
PH
1482PH/37 If a message is not accepted after it has had an id assigned (e.g.
1483 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
1484 "Completed" line in the log. When some messages of this type were
1485 selected by exigrep, they were listed as "not completed". Others were
1486 picked up by some special patterns. I have improved the selection
1487 criteria to be more general.
79749a79 1488
c456d9bb
PH
1489PH/38 The host_find_failed option in the manualroute router can now be set
1490 to "ignore", to completely ignore a host whose IP address cannot be
1491 found. If all hosts are ignored, the behaviour is controlled by the new
1492 host_all_ignored option.
1493
cd9868ec
PH
1494PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1495 homing or because of multiple MX records with /mx) generated more than
1496 one IP address, and the following item turned out to be the local host,
1497 all the secondary addresses of the first item were incorrectly removed
1498 from the list, along with the local host and any following hosts (which
1499 is what is supposed to happen).
1500
ebeaf996
PH
1501PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1502 whoever called Exim into the -H file. In the case of the daemon it was
1503 behaving confusingly. When first started, it used values for whoever
1504 started the daemon, but after a SIGHUP it used the Exim user (because it
1505 calls itself on a restart). I have changed the code so that it now always
1506 uses the Exim user.
1507
2679d413
PH
1508PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1509 message are rejected with the same error (e.g. no authentication or bad
1510 sender address), and a DATA command is nevertheless sent (as can happen
1511 with PIPELINING or a stupid MUA), the error message that was given to the
1512 RCPT commands is included in the rejection of the DATA command. This is
1513 intended to be helpful for MUAs that show only the final error to their
1514 users.

1527
58eb016e 1528PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1529 the response to the final '.' that terminates a message, but only in the
1530 case where the client has not sent further data following the '.'
1531 (unfortunately, this is allowed). However, in many cases there won't be
1532 any further data because there won't be any more messages to send. A call
1533 to select() can be used: if it shows that the input is "ready", there is
1534 either input waiting, or the socket has been closed. An attempt to read
1535 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1536 would have sent an OK response which the client would never have see.
563b63fa
PH
1537 This could lead to message repetition. This fix should cure that, at
1538 least in a lot of common cases.

1544Exim version 4.66
1545-----------------
1546
1547PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1548 fixed by 4.65/MH/01 (is this a record?) are fixed:
1549
1550 (i) An empty string was always treated as zero by the numeric comparison
1551 operators. This behaviour has been restored.
1552
1553 (ii) It is documented that the numeric comparison operators always treat
1554 their arguments as decimal numbers. This was broken in that numbers
1555 starting with 0 were being interpreted as octal.
1556
1557 While fixing these problems I realized that there was another issue that
1558 hadn't been noticed. Values of message_size_limit (both the global option
1559 and the transport option) were treated as octal if they started with 0.
1560 The documentation was vague. These values are now always treated as
1561 decimal, and I will make that clear in the documentation.

1576 child addresses, Exim now panics and dies. Previously, because the count
1577 is held in a short int, deliveries were likely to be lost. As such a
1578 large number of recipients for a single message is ridiculous
1579 (performance will be very, very poor), I have chosen to impose a limit
1580 rather than extend the field.

1586TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1587 leftover -K file (the existence of which was triggered by #402).
1588 While we were at it, introduced process PID as part of the -K
1589 filename. This should rule out race conditions when creating
1590 these files.

1592TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1593 processing considerably. Previous code took too long for large mails,
1594 triggering a timeout which in turn triggers #401.
1595
1596TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1597 in the DK code in transports.c. sendfile() is not really portable,
1598 hence the _LINUX specificness.

1600TF/01 In the add_headers option to the mail command in an Exim filter,

1602 header after the first one which had an odd number of characters
1603 in the field name.

PH
1605PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1606 callout verification, Exim cached a "reject" for the entire domain. This
1607 is correct for most verifications, but it is not correct for a recipient
1608 verification with use_sender or use_postmaster set, because in that case
1609 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1610 case of MAIL FROM:<> rejection from other early rejections (e.g.
1611 rejection of HELO). When verifying a recipient using a non-null MAIL
1612 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1613 Whatever the result of the callout, the value of the domain cache is
1614 left unchanged (for any other kind of callout, getting as far as trying
1615 RCPT means that the domain itself is ok).

1649PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1650 hostname. This is wrong, because it relates to the incoming message (and
1651 probably the interface on which it is arriving) and not to the outgoing
1652 callout (which could be using a different interface). This has been
1653 changed to use the value of the helo_data option from the smtp transport
1654 instead - this is what is used when a message is actually being sent. If
1655 there is no remote transport (possible with a router that sets up host
1656 addresses), $smtp_active_hostname is used.

14aa5a05 1658PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1659 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1660 (a) The code assumed that strncpy() returns a negative number on buffer
1661 overflow, which isn't the case. Replaced with Exim's string_format()
1662 function.
1663 (b) There were several signed/unsigned issues. I just did the minimum
1664 hacking in of casts. There is scope for a larger refactoring.
1665 (c) The code used strcasecmp() which is not a standard C function.
1666 Replaced with Exim's strcmpic() function.
1667 (d) The code set only $1; it now sets $auth1 as well.
1668 (e) A simple test gave the error "authentication client didn't specify
1669 service in request". It would seem that Dovecot has changed its
1670 interface. Fortunately there's a specification; I followed it and
1671 changed what the client sends and it appears to be working now.

1676PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1677 address A is aliased to B and C, where B exists and C does not. Without
1678 -v the output is "A verified" because verification stops after a
1679 successful redirection if more than one address is generated. However,
1680 with -v the child addresses are also verified. Exim was outputting "A
1681 failed to verify" and then showing the successful verification for C,
1682 with its parentage. It now outputs "B failed to verify", showing B's
1683 parentage before showing the successful verification of C.

1686 look up a TXT record in a specific list after matching in a combined

1688
322050c2
PH
1689PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1690 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1691 they consult the DNS. I had assumed they would set it the way they
1692 wanted; and indeed my experiments on Linux seem to show that in some
1693 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1694 To be on the safe side, however, I have now made the interface to
1695 host_find_byname() similar to host_find_bydns(), with an argument
1696 containing the DNS resolver options. The host_find_byname() function now
1697 sets these options at its start, just as host_find_bydns() does. The smtp
1698 transport options dns_qualify_single and dns_search_parents are passed to
1699 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1700 of host_find_byname() use the default settings of RES_DEFNAMES
1701 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1703PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1704 spool_read_header() do less string testing, by means of a preliminary
1705 switch on the second character of optional "-foo" lines. (This is
1706 overdue, caused by the large number of possibilities that now exist.
1707 Originally there were few.) While I was there, I also converted the
1708 str(n)cmp tests so they don't re-test the leading "-" and the first
1709 character, in the hope this might squeeze out yet more improvement.

PH
1711PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1712 flag allowing group syntax was set by the header_syntax check but not
1713 turned off, possible causing trouble later; (2) The flag was not being
1714 set at all for the header_verify test, causing "group"-style headers to
1715 be rejected. I have now set it in this case, and also caused header_
1716 verify to ignore an empty address taken from a group. While doing this, I
1717 came across some other cases where the code for allowing group syntax
1718 while scanning a header line wasn't quite right (mostly, not resetting
1719 the flag correctly in the right place). These bugs could have caused
1720 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1722PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1723 with the "reply" argument non-NULL. The code, however (which originally
1724 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1725 but it didn't always do it. This confused somebody who was copying the
1726 code for some other use. I have removed all the tests.

411ef850
PH
1728PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1729 feature that was used to support insecure browsers during the U.S. crypto
1730 embargo. It requires special client support, and Exim is probably the
1731 only MTA that supported it -- and would never use it because real RSA is
1732 always available. This code has been removed, because it had the bad
1733 effect of slowing Exim down by computing (never used) parameters for the
1734 RSA_EXPORT functionality.

7befa435
PH
1736PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1737 authenticator to fail if there's a tab character in the incoming data
1738 (there should never be unless someone is messing about, as it's supposed
1739 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1740 if the connection is using TLS or if the remote IP is the same as the
1741 local IP, and the "valid-client-cert option" if a client certificate has
1742 been verified.

1773
1774PH/30 Exim was sometimes attempting to deliver messages that had suffered
1775 address errors (4xx response to RCPT) over the same connection as other
1776 messages routed to the same hosts. Such deliveries are always "forced",
1777 so retry times are not inspected. This resulted in far too many retries
1778 for the affected addresses. The effect occurred only when there were more
1779 hosts than the hosts_max_try setting in the smtp transport when it had
1780 the 4xx errors. Those hosts that it had tried were not added to the list
1781 of hosts for which the message was waiting, so if all were tried, there
1782 was no problem. Two fixes have been applied:
1783
1784 (i) If there are any address or message errors in an SMTP delivery, none
1785 of the hosts (tried or untried) are now added to the list of hosts
1786 for which the message is waiting, so the message should not be a
1787 candidate for sending over the same connection that was used for a
1788 successful delivery of some other message. This seems entirely
1789 reasonable: after all the message is NOT "waiting for some host".
1790 This is so "obvious" that I'm not sure why it wasn't done
1791 previously. Hope I haven't missed anything, but it can't do any
1792 harm, as the worst effect is to miss an optimization.
1793
1794 (ii) If, despite (i), such a delivery is accidentally attempted, the
1795 routing retry time is respected, so at least it doesn't keep
1796 hammering the server.

PH
1811PH/35 The error "getsockname() failed: connection reset by peer" was being
1812 written to the panic log as well as the main log, but it isn't really
1813 panic-worthy as it just means the connection died rather early on. I have
1814 removed the panic log writing for the ECONNRESET error when getsockname()
1815 fails.
1816
48c7f9e2
PH
1817PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1818 runs only) independently of the message's sender address. This meant
1819 that, if the 4xx error was in fact related to the sender, a different
1820 message to the same recipient with a different sender could confuse
1821 things. In particualar, this can happen when sending to a greylisting
1822 server, but other circumstances could also provoke similar problems.
1823 I have changed the default so that the retry time for these errors is now
1824 based a combination of the sender and recipient addresses. This change
1825 can be overridden by setting address_retry_include_sender=false in the
1826 smtp transport.

2094PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2097 tcp-wrappers gives "deny", whereas what one would like would be some
2098 kind of temporary error. A kludge has been added to help with this.
2099 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2100 554 error is used if errno is still zero or contains ENOENT (which occurs
2101 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2138PH/01 The code for finding all the local interface addresses on a FreeBSD

2141 code found IPv4 interfaces correctly, but gave incorrect values for the
2142 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2143 that it would not match correctly against @[] and not recognize the IPv6
2144 addresses as local.

2187 autoreply, Exim could try to deliver to a non-existent relative file

2223 Instead, it always explicitly searches for A/AAAA records. This avoids
2224 major problems that occur when a DNS server includes only records of one
2225 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2226 fixed another bug: if SRV records were looked up and the corresponding
2227 address records were *not* found in the additional section, the port
2228 values from the SRV records were lost.

2230PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2238PH/19 When calculating a retry time, Exim used to measure the "time since
2239 failure" by looking at the "first failed" field in the retry record. Now
2240 it does not use this if it is later than than the arrival time of the
2241 message. Instead it uses the arrival time. This makes for better
2242 behaviour in cases where some deliveries succeed, thus re-setting the
2243 "first failed" field. An example is a quota failure for a huge message
2244 when small messages continue to be delivered. Without this change, the
2245 "time since failure" will always be short, possible causing more frequent
2246 delivery attempts for the huge message than are intended.

2346 files with open(), and sets the required mode explicitly. Thus, these
2347 files were ending up world-writeable. This was not a big issue, because,
2348 being within the spool directory, they were not world-accessible. I have
2349 created a function called modefopen, which takes an additional mode
2350 argument. It sets umask(777), creates the file, chmods it to the required
2351 mode, then resets the umask. All the relevant calls to fopen() in the
2352 content scanning code have been changed to use this function.

2360PH/45 When the plaintext authenticator is running as a client, the server's
2361 challenges are checked to ensure they are valid base64 strings. By
2362 default, the authentication attempt is cancelled if an invalid string is
2363 received. Setting client_ignore_invalid_base64 true ignores these errors.
2364 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2365 they are received. Thus, the responses can be made to depend on the
2366 challenges. If an invalid string is ignored, an empty string is placed in
2367 the variable.

2387PH/52 Two bugs concerned with error handling when the smtp transport is
2388 used in LMTP mode:
2389
2390 (i) Exim was not creating retry information for temporary errors given
2391 for individual recipients after the DATA command when the smtp transport
2392 was used in LMTP mode. This meant that they could be retried too
2393 frequently, and not timed out correctly.
2394
2395 (ii) Exim was setting the flag that allows error details to be returned
2396 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2397 recipients that were returned after the DATA command.
2398
2399PH/53 This is related to PH/52, but is more general: for any failing address,
2400 when detailed error information was permitted to be returned to the
2401 sender, but the error was temporary, then after the final timeout, only
2402 "retry timeout exceeded" was returned. Now it returns the full error as
2403 well as "retry timeout exceeded".

2473PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2474 function verify_get_ident() calls ip_connect() to connect a socket, but
2475 if the "connect()" function timed out, ip_connect() used to close the
2476 socket. However, verify_get_ident() also closes the socket later, and in
2477 between Exim writes to the log, which may get opened at this point. When
2478 the socket was closed in ip_connect(), the log could get the same file
2479 descriptor number as the socket. This naturally causes chaos. The fix is
2480 not to close the socket in ip_connect(); the socket should be closed by
2481 the function that creates it. There was only one place in the code where
2482 this was missing, in the iplookup router, which I don't think anybody now
2483 uses, but I've fixed it anyway.

2506
2507 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2509
2510 (3) Reset the variables that are obtained from the first argument of
2511 ${prvscheck and used in the second argument before leaving the code,
2512 because their memory is reclaimed, so using them afterwards may do
2513 silly things.
2514
2515 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2516 one (it's much easier than Tom thought :-).

2540 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2541 not being looked up in the rDNS to get a host name, Exim was showing the
2542 IP address twice in Received: lines, even though the IP addresses were
2543 identical. For example:
2544
2545 Received: from [1.2.3.4] (helo=[1.2.3.4])
2546
2547 However, if the real host name was known, it was omitting the HELO data
2548 if it matched the actual IP address. This has been tidied up so that it
2549 doesn't show the same IP address twice.

2575PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2577
2578 Auto-submitted: auto-generated
2579
2580 in the messages that it generates (bounce messages and others, such as
2581 warnings). In the case of bounce messages for non-SMTP mesages, there was
2582 also a typo: it was using "Auto_submitted" (underscore instead of
2583 hyphen). Since every message generated by Exim is necessarily in response
2584 to another message, thes have all been changed to:
2585
2586 Auto-Submitted: auto-replied
2587
2588 in accordance with these statements in the RFC:
2589
2590 The auto-replied keyword:
2591
2592 - SHOULD be used on messages sent in direct response to another

2641 addresses acquired from the DNS when checking that the found name did
2642 have the original IP as one of its addresses. Since any found IPv6
2643 addresses are likely to be in abbreviated form, the comparison could
2644 fail. Luckily, there already exists a function for doing the comparison
2645 by converting both addresses to binary, so now that is used instead of
2646 the text comparison.

2767 - Username/password not passed on to radius server due to wrong length.

2944 with the definition in sysexits.h (which is #included earlier).
2945 Fortunately, Exim does not actually use EX_OK. The code used to try to
2946 preserve the sysexits.h value, by assumimg that macro definitions were
2947 scanned for macro replacements. I have been disabused of this notion,

2955 doesn't have to be particularly precise.

3154TK/01 Added Yahoo DomainKeys support via libdomainkeys. See
3155 doc/experimental-spec.txt for details. (http://domainkeys.sf.net)

3158
3159TK/03 Fix ACL "regex" condition not being available in MIME ACL.
3160
3161PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3162 to test Sieve filters that use "vacation".
3163
3164PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3165 that changes the way the GnuTLS parameters are stored in the cache file.
3166 The new format can be generated externally. For backward compatibility,
3167 if the data in the cache doesn't make sense, Exim assumes it has read an
3168 old-format file, and it generates new data and writes a new file. This
3169 means that you can't go back to an older release without removing the
3170 file.
3171
3172PH/03 A redirect router that has both "unseen" and "one_time" set does not
3173 work if there are any delivery delays because "one_time" forces the
3174 parent to be marked "delivered", so its unseen clone is never tried
3175 again. For this reason, Exim now forbids the simultaneous setting of
3176 these two options.
3177
3178PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3179 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3180 entry if you want to know the details. The fix, however, neglected to
3181 consider the case when local delivery batching is involved. The test for
3182 "previously delivered" was not happening when checking to see if an
3183 address could be batched with a previous (undelivered) one; under
3184 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3185 address.
1a46a8c5
PH
3186
3187PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3188 in its include files, and this causes problems building Exim.
3189
3190PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3191 header_syntax) but Exim was just ignoring anything given after a slash.
3192 In particular, this caused confusion with an attempt to use "verify =
3193 reverse_host_lookup/defer_ok". An error is now given when options are
3194 supplied for verify items that do not have them. (Maybe reverse_host_
3195 lookup should have a defer_ok option, but that's a different point.)
3196
3197PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3198 defined by RFC 821) to 2048, because there were problems with some AUTH
3199 commands, and RFC 1869 says the size should be increased for extended
3200 SMTP commands that take arguments.
3201
3202PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3203 Finch).
3204
3205PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an
3206 "unknown" error; now it says that the functionality isn't in the binary.

3208PH/10 Added a nasty fudge to try to recognize and flatten LDAP passwords in
3209 an address' error message when a string expansion fails (syntax or
f331f3b6
PH
3210 whatever). Otherwise the password may appear in the log. Following change
3211 PH/42 below, there is no longer a chance of it appearing in a bounce
3212 message.

PH
3230PH/15 Further to TK/02 and TK/03 above, tidied up the tables of what conditions
3231 and controls are allowed in which ACLs. There were a couple of minor
3232 errors. Some of the entries in the conditions table (which is a table of
3233 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3234 negation of where the condition IS allowed.

PH
3238PH/17 The API for radiusclient changed at release 0.4.0. Unfortunately, the
3239 header file does not have a version number, so I've had to invent a new
3240 value for RADIUS_LIB_TYPE, namely "RADIUSCLIENTNEW" to request the new
3241 API. The code is untested by me (my Linux distribution still has 0.3.2 of
3242 radiusclient), but it was contributed by a Radius user.

3246
901f42cb
PH
3247PH/19 When an Exim process that is running as root has to create an Exim log
3248 file, it does so in a subprocess that runs as exim:exim so as to get the
3249 ownership right at creation (otherwise, other Exim processes might see
3250 the file with the wrong ownership). There was no test for failure of this
3251 fork() call, which would lead to the process getting stuck as it waited
3252 for a non-existent subprocess. Forks do occasionally fail when resources
3253 run out. I reviewed all the other calls to fork(); they all seem to check
3254 for failure.
3255
f9b9210e
PH
3256PH/20 When checking for unexpected SMTP input at connect time (before writing
3257 the banner), Exim was not dealing correctly with a non-positive return
3258 from the read() function. If the client had disconnected by this time,
3259 the result was a log entry for a synchronization error with an empty
3260 string after "input=" when read() returned zero. If read() returned -1
3261 (an event I could not check), uninitialized data bytes were printed.
3262 There were reports of junk text (parts of files, etc) appearing after
3263 "input=".

3270PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then
3271 forgetting to use the resulting value; it was using the unexpanded value.
3272
c5ddb310
PH
3273PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3274 hadn't been configured. The fix is from Juergen Kreileder, who
3275 understands it better than I do:
3276
3277 "Here's what I see happening with three configured cyrus_sasl
3278 authenticators configured (plain, login, cram-md5):
3279
3280 On startup auth_cyrus_sasl_init() gets called for each of these.
3281 This means three calls to sasl_listmech() without a specified mech_list.
3282 => SASL tests which mechs of all available mechs actually work
3283 => three warnings about OTP not working
3284 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3285
3286 With the patch, sasl_listmech() also gets called three times. But now
3287 SASL's mech_list option is set to the server_mech specified in the the
3288 authenticator. Or in other words, the answer from sasl_listmech()
3289 gets limited to just the mech you're testing for (which is different
3290 for each call.)
3291 => the return list contains just 'plain' or 'login', 'cram-md5' or
3292 nothing depending on the value of ob->server_mech.
3293
3294 I've just tested the patch: Authentication still works fine,
3295 unavailable mechs specified in the exim configuration are still
3296 caught, and the auth.log warnings about OTP are gone."

PH
3306PH/27 $acl_verify_message is now set immediately after the failure of a
3307 verification in an ACL, and so is available in subsequent modifiers. In
3308 particular, the message can be preserved by coding like this:
3309
3310 warn !verify = sender
3311 set acl_m0 = $acl_verify_message
3312
3313 Previously, $acl_verify_message was set only while expanding "message"
3314 and "log_message" when a very denied access.

PH
3327PH/30 In these circumstances:
3328 . Two addresses routed to the same list of hosts;
3329 . First host does not offer TLS;
3330 . First host accepts first address;
3331 . First host gives temporary error to second address;
3332 . Second host offers TLS and a TLS session is established;
3333 . Second host accepts second address.
3334 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3335 and peerdn, if requested) that were in fact used only for the second
3336 address.

PH
3338PH/31 When doing a callout as part of verifying an address, Exim was not paying
3339 attention to any local part prefix or suffix that was matched by the
3340 router that accepted the address. It now behaves in the same way as it
3341 does for delivery: the affixes are removed from the local part unless
3342 rcpt_include_affixes is set on the transport.

3350PH/34 Change 4.50/80 broke Exim in that it could no longer handle cases where

3354PH/35 ACL_WHERE_MIME is now declared unconditionally, to avoid too much code

3359
d7174846
PH
3360PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3361 the grounds that routing the same address twice would always produce the
3362 same answer. This might have been true once, but it is certainly no
3363 longer true now. Routing a child address may depend on the previous
3364 routing that produced that child. Some complicated redirection strategies
3365 went wrong when messages had multiple recipients, and made Exim's
3366 behaviour dependent on the order in which the addresses were given.
3367
3368 I have moved the duplicate checking until after the routing is complete.
