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.

18 utilities have not been installed.

249TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
250
251 When a queue runner is handling a message, Exim first routes the
252 recipient addresses, during which it prunes them based on the retry
253 hints database. After that it attempts to deliver the message to
254 any remaining recipients. It then updates the hints database using
255 the retry rules.
256
257 So if a recipient address works intermittently, it can get repeatedly
258 deferred at routing time. The retry hints record remains fresh so the
259 address never reaches the final cutoff time.
260
261 This is a fairly common occurrence when a user is bumping up against
262 their storage quota. Exim had some logic in its local delivery code
263 to deal with this. However it did not apply to per-recipient defers
264 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
265
1ddeb334
TF
266 This change adds a proper retry rule check during routing so that the
267 final cutoff time is checked against the message's age. We only do
268 this check if there is an address retry record and there is not a
269 domain retry record; this implies that previous attempts to handle
270 the address had the retry_use_local_parts option turned on. We use
271 this as an approximation for the destination being like a local
272 delivery, as in LMTP.
67bd1ab3
TF
273
274 I suspect this new check makes the old local delivery cutoff check
275 redundant, but I have not verified this so I left the code in place.

277TF/02 Correct gecos expansion when From: is a prefix of the username.
278
279 Test 0254 submits a message to Exim with the header
280
281 Resent-From: f
282
283 When I ran the test suite under the user fanf2, Exim expanded
284 the header to contain my full name, whereas it should have added
285 a Resent-Sender: header. It erroneously treats any prefix of the
286 username as equal to the username.
287
288 This change corrects that bug.

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

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

1210
1211 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1212 were called 'true' and it seems that C99 defines that as a reserved
1213 keyword to be used with 'bool' variable types. That means you could
1214 not include C99-style headers which use bools without triggering
1215 build errors in sieve.c.

1230Exim version 4.68
1231-----------------
1232
1233PH/01 Another patch from the Sieve maintainer.
1234
6a3bceb1
PH
1235PH/02 When an IPv6 address is converted to a string for single-key lookup
1236 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1237 dots are used instead of colons so that keys in lsearch files need not
1238 contain colons. This was done some time before quoting was made available
1239 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1240 (notated using the quote facility) so as to distinguish them from IPv4
1241 keys. This meant that lookups for IP addresses in host lists did not work
1242 for iplsearch lookups.
1243
1244 This has been fixed by arranging for IPv6 addresses to be expressed with
1245 colons if the lookup type is iplsearch. This is not incompatible, because
1246 previously such lookups could never work.
1247
1248 The situation is now rather anomolous, since one *can* have colons in
1249 ordinary lsearch keys. However, making the change in all cases is
1250 incompatible and would probably break a number of configurations.
1251
2e30fa9d
TK
1252TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
1253 version.
1254
0806a9c5
MH
1255MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1256 conversion specification without a maximum field width, thereby enabling
1257 a rogue spamd server to cause a buffer overflow. While nobody in their
1258 right mind would setup Exim to query an untrusted spamd server, an
1259 attacker that gains access to a server running spamd could potentially
1260 exploit this vulnerability to run arbitrary code as the Exim user.

1263 $primary_hostname instead of what libspf2 thinks the hosts name is.
1264
0f2cbd1b
MH
1265MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1266 a directory entry by the name of the lookup key. Previously, if a
1267 symlink pointed to a non-existing file or a file in a directory that
1268 Exim lacked permissions to read, a lookup for a key matching that
1269 symlink would fail. Now it is enough that a matching directory entry
1270 exists, symlink or not. (Bugzilla 503.)

1310PH/18 If a system quota error occurred while trying to create the file for
1311 a maildir delivery, the message "Mailbox is full" was not appended to the

1313 only to a quota excession during the actual writing of the file.

1341 issue a MAIL command.
1342
431b7361
PH
1343PH/02 In an ACL statement such as
1344
1345 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1346
1347 if a client was not listed at all, or was listed with a value other than
1348 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1349 the condition was not true (as it should be), so access was not denied.
1350 The bug was that the ! inversion was incorrectly passed on to the second
1351 item. This has been fixed.

1354 = and & when the dns lookup returns more than one IP address.

54fc8428
PH
1359PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_

1367 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
1368 including adding "make clean"; (3) Added -fPIC when compiling the test
1369 dynamically loaded module, to get rid of a warning.

MH
1371MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce

f0872424
PH
1375PH/07 There was a bug in the dovecot authenticator such that the value of
1376 $auth1 could be overwritten, and so not correctly preserved, after a
1377 successful authentication. This usually meant that the value preserved by
1378 the server_setid option was incorrect.

1384PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1385 run for batched SMTP input. It is now run at the start of every message
1386 in the batch. While fixing this I discovered that the process information
1387 (output by running exiwhat) was not always getting set for -bs and -bS
1388 input. This is fixed, and it now also says "batched" for BSMTP.

5a11a7b4
PH
1439PH/27 When a message times out after an over-quota error from an Exim-imposed
1440 quota, the bounce message says "mailbox is full". This message was not
1441 being given when it was a system quota that was exceeded. It now should
1442 be the same.
1443
0e20aff9
MH
1444MH/03 Made $recipients available in local_scan(). local_scan() already has
1445 better access to the recipient list through recipients_list[], but
1446 $recipients can be useful in postmaster-provided expansion strings.
1447
ca86f471
PH
1448PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1449 in the case of a MAIL command with additional options following the
1450 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1451 were accidentally chopped off.
1452
a14e5636
PH
1453PH/29 SMTP synchronization checks are implemented when a command is read -
1454 there is a check that no more input is waiting when there shouldn't be
1455 any. However, for some commands, a delay in an ACL can mean that it is
1456 some time before the response is written. In this time, more input might
1457 arrive, invalidly. So now there are extra checks after an ACL has run for
1458 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1459 pipelining has not been advertised.
1460
ec95d1a6

PH
1467PH/32 Change the Dovecot authenticator to use read() and write() on the socket

1469 reported on Solaris.
1470
58c01c94
PH
1471PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1472 Exim which did not show up earlier: it was assuming that a call to
1473 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1474 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1475 was a macro that became an assignment, so it seemed to work. This has
1476 changed to a proper function call with a void return, hence the compile
1477 error. Exim's code has been fixed.

79749a79
PH
1486PH/37 If a message is not accepted after it has had an id assigned (e.g.
1487 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
1488 "Completed" line in the log. When some messages of this type were
1489 selected by exigrep, they were listed as "not completed". Others were

1491 criteria to be more general.
79749a79 1492
c456d9bb
PH
1493PH/38 The host_find_failed option in the manualroute router can now be set
1494 to "ignore", to completely ignore a host whose IP address cannot be

1496 host_all_ignored option.
1497
cd9868ec
PH
1498PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1499 homing or because of multiple MX records with /mx) generated more than
1500 one IP address, and the following item turned out to be the local host,
1501 all the secondary addresses of the first item were incorrectly removed
1502 from the list, along with the local host and any following hosts (which
1503 is what is supposed to happen).
1504
ebeaf996
PH
1505PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1506 whoever called Exim into the -H file. In the case of the daemon it was
1507 behaving confusingly. When first started, it used values for whoever
1508 started the daemon, but after a SIGHUP it used the Exim user (because it
1509 calls itself on a restart). I have changed the code so that it now always
1510 uses the Exim user.
1511
2679d413
PH
1512PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1513 message are rejected with the same error (e.g. no authentication or bad
1514 sender address), and a DATA command is nevertheless sent (as can happen
1515 with PIPELINING or a stupid MUA), the error message that was given to the
1516 RCPT commands is included in the rejection of the DATA command. This is
1517 intended to be helpful for MUAs that show only the final error to their
1518 users.

1531
58eb016e 1532PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1533 the response to the final '.' that terminates a message, but only in the
1534 case where the client has not sent further data following the '.'
1535 (unfortunately, this is allowed). However, in many cases there won't be
1536 any further data because there won't be any more messages to send. A call
1537 to select() can be used: if it shows that the input is "ready", there is
1538 either input waiting, or the socket has been closed. An attempt to read
1539 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1540 would have sent an OK response which the client would never have see.
563b63fa

1550
1551PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1552 fixed by 4.65/MH/01 (is this a record?) are fixed:
1553
1554 (i) An empty string was always treated as zero by the numeric comparison
1555 operators. This behaviour has been restored.
1556
1557 (ii) It is documented that the numeric comparison operators always treat
1558 their arguments as decimal numbers. This was broken in that numbers
1559 starting with 0 were being interpreted as octal.
1560
1561 While fixing these problems I realized that there was another issue that
1562 hadn't been noticed. Values of message_size_limit (both the global option
1563 and the transport option) were treated as octal if they started with 0.
1564 The documentation was vague. These values are now always treated as
1565 decimal, and I will make that clear in the documentation.

1579PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1580 child addresses, Exim now panics and dies. Previously, because the count
1581 is held in a short int, deliveries were likely to be lost. As such a
1582 large number of recipients for a single message is ridiculous
1583 (performance will be very, very poor), I have chosen to impose a limit
1584 rather than extend the field.

1590TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1591 leftover -K file (the existence of which was triggered by #402).
1592 While we were at it, introduced process PID as part of the -K
1593 filename. This should rule out race conditions when creating
1594 these files.

1596TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1597 processing considerably. Previous code took too long for large mails,

1599
1600TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1601 in the DK code in transports.c. sendfile() is not really portable,

1604TF/01 In the add_headers option to the mail command in an Exim filter,

1606 header after the first one which had an odd number of characters
1607 in the field name.

PH
1609PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1610 callout verification, Exim cached a "reject" for the entire domain. This
1611 is correct for most verifications, but it is not correct for a recipient
1612 verification with use_sender or use_postmaster set, because in that case
1613 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1614 case of MAIL FROM:<> rejection from other early rejections (e.g.
1615 rejection of HELO). When verifying a recipient using a non-null MAIL
1616 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1617 Whatever the result of the callout, the value of the domain cache is
1618 left unchanged (for any other kind of callout, getting as far as trying
1619 RCPT means that the domain itself is ok).

1653PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1654 hostname. This is wrong, because it relates to the incoming message (and
1655 probably the interface on which it is arriving) and not to the outgoing
1656 callout (which could be using a different interface). This has been
1657 changed to use the value of the helo_data option from the smtp transport
1658 instead - this is what is used when a message is actually being sent. If
1659 there is no remote transport (possible with a router that sets up host
1660 addresses), $smtp_active_hostname is used.

7befa435 1663 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1664 (a) The code assumed that strncpy() returns a negative number on buffer
1665 overflow, which isn't the case. Replaced with Exim's string_format()
1666 function.
1667 (b) There were several signed/unsigned issues. I just did the minimum
1668 hacking in of casts. There is scope for a larger refactoring.
1669 (c) The code used strcasecmp() which is not a standard C function.
1670 Replaced with Exim's strcmpic() function.
1671 (d) The code set only $1; it now sets $auth1 as well.
1672 (e) A simple test gave the error "authentication client didn't specify
1673 service in request". It would seem that Dovecot has changed its
1674 interface. Fortunately there's a specification; I followed it and
1675 changed what the client sends and it appears to be working now.

1680PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1681 address A is aliased to B and C, where B exists and C does not. Without
1682 -v the output is "A verified" because verification stops after a
1683 successful redirection if more than one address is generated. However,
1684 with -v the child addresses are also verified. Exim was outputting "A
1685 failed to verify" and then showing the successful verification for C,
1686 with its parentage. It now outputs "B failed to verify", showing B's
1687 parentage before showing the successful verification of C.

1692
322050c2
PH
1693PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1694 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1695 they consult the DNS. I had assumed they would set it the way they
1696 wanted; and indeed my experiments on Linux seem to show that in some
1697 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1698 To be on the safe side, however, I have now made the interface to
1699 host_find_byname() similar to host_find_bydns(), with an argument
1700 containing the DNS resolver options. The host_find_byname() function now
1701 sets these options at its start, just as host_find_bydns() does. The smtp
1702 transport options dns_qualify_single and dns_search_parents are passed to
1703 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1704 of host_find_byname() use the default settings of RES_DEFNAMES
1705 (qualify_single) but not RES_DNSRCH (search_parents).

1707PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1708 spool_read_header() do less string testing, by means of a preliminary
1709 switch on the second character of optional "-foo" lines. (This is
1710 overdue, caused by the large number of possibilities that now exist.
1711 Originally there were few.) While I was there, I also converted the
1712 str(n)cmp tests so they don't re-test the leading "-" and the first
1713 character, in the hope this might squeeze out yet more improvement.

PH
1715PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1716 flag allowing group syntax was set by the header_syntax check but not
1717 turned off, possible causing trouble later; (2) The flag was not being
1718 set at all for the header_verify test, causing "group"-style headers to
1719 be rejected. I have now set it in this case, and also caused header_
1720 verify to ignore an empty address taken from a group. While doing this, I
1721 came across some other cases where the code for allowing group syntax
1722 while scanning a header line wasn't quite right (mostly, not resetting
1723 the flag correctly in the right place). These bugs could have caused
1724 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1726PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1727 with the "reply" argument non-NULL. The code, however (which originally
1728 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1729 but it didn't always do it. This confused somebody who was copying the
1730 code for some other use. I have removed all the tests.

PH
1732PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1733 feature that was used to support insecure browsers during the U.S. crypto
1734 embargo. It requires special client support, and Exim is probably the
1735 only MTA that supported it -- and would never use it because real RSA is
1736 always available. This code has been removed, because it had the bad
1737 effect of slowing Exim down by computing (never used) parameters for the
1738 RSA_EXPORT functionality.

PH
1740PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1741 authenticator to fail if there's a tab character in the incoming data
1742 (there should never be unless someone is messing about, as it's supposed
1743 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1744 if the connection is using TLS or if the remote IP is the same as the
1745 local IP, and the "valid-client-cert option" if a client certificate has
1746 been verified.

1777
1778PH/30 Exim was sometimes attempting to deliver messages that had suffered
1779 address errors (4xx response to RCPT) over the same connection as other
1780 messages routed to the same hosts. Such deliveries are always "forced",
1781 so retry times are not inspected. This resulted in far too many retries
1782 for the affected addresses. The effect occurred only when there were more
1783 hosts than the hosts_max_try setting in the smtp transport when it had
1784 the 4xx errors. Those hosts that it had tried were not added to the list
1785 of hosts for which the message was waiting, so if all were tried, there
1786 was no problem. Two fixes have been applied:
1787
1788 (i) If there are any address or message errors in an SMTP delivery, none
1789 of the hosts (tried or untried) are now added to the list of hosts
1790 for which the message is waiting, so the message should not be a
1791 candidate for sending over the same connection that was used for a
1792 successful delivery of some other message. This seems entirely
1793 reasonable: after all the message is NOT "waiting for some host".
1794 This is so "obvious" that I'm not sure why it wasn't done
1795 previously. Hope I haven't missed anything, but it can't do any
1796 harm, as the worst effect is to miss an optimization.
1797
1798 (ii) If, despite (i), such a delivery is accidentally attempted, the
1799 routing retry time is respected, so at least it doesn't keep
1800 hammering the server.

PH
1815PH/35 The error "getsockname() failed: connection reset by peer" was being
1816 written to the panic log as well as the main log, but it isn't really
1817 panic-worthy as it just means the connection died rather early on. I have
1818 removed the panic log writing for the ECONNRESET error when getsockname()
1819 fails.
1820
48c7f9e2
PH
1821PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1822 runs only) independently of the message's sender address. This meant
1823 that, if the 4xx error was in fact related to the sender, a different
1824 message to the same recipient with a different sender could confuse
1825 things. In particualar, this can happen when sending to a greylisting
1826 server, but other circumstances could also provoke similar problems.
1827 I have changed the default so that the retry time for these errors is now
1828 based a combination of the sender and recipient addresses. This change
1829 can be overridden by setting address_retry_include_sender=false in the
1830 smtp transport.

2098PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2100 Unfortunately, if there is a major crisis, such as a disk failure,
2101 tcp-wrappers gives "deny", whereas what one would like would be some
2102 kind of temporary error. A kludge has been added to help with this.
2103 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2104 554 error is used if errno is still zero or contains ENOENT (which occurs
2105 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2106 451 error is used.

2142PH/01 The code for finding all the local interface addresses on a FreeBSD
2143 system running IPv6 was broken. This may well have applied to all BSD
2144 systems, as well as to others that have similar system calls. The broken
2145 code found IPv4 interfaces correctly, but gave incorrect values for the
2146 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2147 that it would not match correctly against @[] and not recognize the IPv6
2148 addresses as local.

2189 syntactically invalid From: or Reply-to: line, and a filter used this to
2190 generate an autoreply, and therefore failed to obtain an address for the
2191 autoreply, Exim could try to deliver to a non-existent relative file
2192 name, causing unrelated and misleading errors. What now happens is that

2211 non-existent - all you got was a failure to exec. I have made two
2212 changes:
2213
2214 (a) Failures to set uid/gid, the current directory, or a process leader
2215 in a subprocess such as that created by queryprogram now generate
2216 suitable debugging ouput when -d is set.
2217

2219 outputs suitable debugging information if -d is set, and then runs
2220 the subprocess without attempting to change uid/gid.

2225PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2226 additional section of a DNS packet that returns MX or SRV records.
2227 Instead, it always explicitly searches for A/AAAA records. This avoids
2228 major problems that occur when a DNS server includes only records of one
2229 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2230 fixed another bug: if SRV records were looked up and the corresponding
2231 address records were *not* found in the additional section, the port
2232 values from the SRV records were lost.
2233
ea49d0e1
PH
2234PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

2238PH/18 If quota_warn_message contains a From: header, Exim now refrains from

2241
727071f8
PH
2242PH/19 When calculating a retry time, Exim used to measure the "time since
2243 failure" by looking at the "first failed" field in the retry record. Now
2244 it does not use this if it is later than than the arrival time of the
2245 message. Instead it uses the arrival time. This makes for better
2246 behaviour in cases where some deliveries succeed, thus re-setting the
2247 "first failed" field. An example is a quota failure for a huge message
2248 when small messages continue to be delivered. Without this change, the
2249 "time since failure" will always be short, possible causing more frequent
2250 delivery attempts for the huge message than are intended.

2350 files with open(), and sets the required mode explicitly. Thus, these
2351 files were ending up world-writeable. This was not a big issue, because,
2352 being within the spool directory, they were not world-accessible. I have
2353 created a function called modefopen, which takes an additional mode
2354 argument. It sets umask(777), creates the file, chmods it to the required
2355 mode, then resets the umask. All the relevant calls to fopen() in the
2356 content scanning code have been changed to use this function.

2364PH/45 When the plaintext authenticator is running as a client, the server's
2365 challenges are checked to ensure they are valid base64 strings. By
2366 default, the authentication attempt is cancelled if an invalid string is
2367 received. Setting client_ignore_invalid_base64 true ignores these errors.
2368 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2369 they are received. Thus, the responses can be made to depend on the
2370 challenges. If an invalid string is ignored, an empty string is placed in
2371 the variable.

2391PH/52 Two bugs concerned with error handling when the smtp transport is
2392 used in LMTP mode:
2393
2394 (i) Exim was not creating retry information for temporary errors given
2395 for individual recipients after the DATA command when the smtp transport
2396 was used in LMTP mode. This meant that they could be retried too
2397 frequently, and not timed out correctly.
2398
2399 (ii) Exim was setting the flag that allows error details to be returned
2400 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2401 recipients that were returned after the DATA command.
2402
2403PH/53 This is related to PH/52, but is more general: for any failing address,
2404 when detailed error information was permitted to be returned to the
2405 sender, but the error was temporary, then after the final timeout, only
2406 "retry timeout exceeded" was returned. Now it returns the full error as
2407 well as "retry timeout exceeded".

2477PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2478 function verify_get_ident() calls ip_connect() to connect a socket, but
2479 if the "connect()" function timed out, ip_connect() used to close the
2480 socket. However, verify_get_ident() also closes the socket later, and in
2481 between Exim writes to the log, which may get opened at this point. When
2482 the socket was closed in ip_connect(), the log could get the same file
2483 descriptor number as the socket. This naturally causes chaos. The fix is
2484 not to close the socket in ip_connect(); the socket should be closed by
2485 the function that creates it. There was only one place in the code where
2486 this was missing, in the iplookup router, which I don't think anybody now
2487 uses, but I've fixed it anyway.

2510
2511 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2513
2514 (3) Reset the variables that are obtained from the first argument of
2515 ${prvscheck and used in the second argument before leaving the code,
2516 because their memory is reclaimed, so using them afterwards may do
2517 silly things.
2518
2519 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2520 one (it's much easier than Tom thought :-).

2544 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2545 not being looked up in the rDNS to get a host name, Exim was showing the
2546 IP address twice in Received: lines, even though the IP addresses were
2547 identical. For example:
2548
2549 Received: from [1.2.3.4] (helo=[1.2.3.4])
2550
2551 However, if the real host name was known, it was omitting the HELO data
2552 if it matched the actual IP address. This has been tidied up so that it
2553 doesn't show the same IP address twice.

2581
2582 Auto-submitted: auto-generated

2584 in the messages that it generates (bounce messages and others, such as
2585 warnings). In the case of bounce messages for non-SMTP mesages, there was
2586 also a typo: it was using "Auto_submitted" (underscore instead of
2587 hyphen). Since every message generated by Exim is necessarily in response
2588 to another message, thes have all been changed to:
2589
2590 Auto-Submitted: auto-replied
2591
2592 in accordance with these statements in the RFC:
2593
2594 The auto-replied keyword:

2645 addresses acquired from the DNS when checking that the found name did
2646 have the original IP as one of its addresses. Since any found IPv6
2647 addresses are likely to be in abbreviated form, the comparison could
2648 fail. Luckily, there already exists a function for doing the comparison
2649 by converting both addresses to binary, so now that is used instead of
2650 the text comparison.

2770 - Error returned from rc_read_config was caught wrongly
2771 - Username/password not passed on to radius server due to wrong length.

2948 with the definition in sysexits.h (which is #included earlier).
2949 Fortunately, Exim does not actually use EX_OK. The code used to try to
2950 preserve the sysexits.h value, by assumimg that macro definitions were
2951 scanned for macro replacements. I have been disabused of this notion,

2957 This seems wrong - if the receiver was accepting one byte at a time it
2958 would take for ever. The timeout is now adjusted when this happens. It
2959 doesn't have to be particularly precise.

3158TK/01 Added Yahoo DomainKeys support via libdomainkeys. See
3159 doc/experimental-spec.txt for details. (http://domainkeys.sf.net)

PH
3162
3163TK/03 Fix ACL "regex" condition not being available in MIME ACL.
3164
3165PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3166 to test Sieve filters that use "vacation".
3167
3168PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3169 that changes the way the GnuTLS parameters are stored in the cache file.
3170 The new format can be generated externally. For backward compatibility,
3171 if the data in the cache doesn't make sense, Exim assumes it has read an
3172 old-format file, and it generates new data and writes a new file. This
3173 means that you can't go back to an older release without removing the
3174 file.
3175
3176PH/03 A redirect router that has both "unseen" and "one_time" set does not
3177 work if there are any delivery delays because "one_time" forces the
3178 parent to be marked "delivered", so its unseen clone is never tried
3179 again. For this reason, Exim now forbids the simultaneous setting of
3180 these two options.
3181
3182PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3183 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3184 entry if you want to know the details. The fix, however, neglected to
3185 consider the case when local delivery batching is involved. The test for
3186 "previously delivered" was not happening when checking to see if an
3187 address could be batched with a previous (undelivered) one; under
3188 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3189 address.

PH
3190
3191PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3192 in its include files, and this causes problems building Exim.
3193
3194PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3195 header_syntax) but Exim was just ignoring anything given after a slash.
3196 In particular, this caused confusion with an attempt to use "verify =
3197 reverse_host_lookup/defer_ok". An error is now given when options are
3198 supplied for verify items that do not have them. (Maybe reverse_host_
3199 lookup should have a defer_ok option, but that's a different point.)
3200
3201PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3202 defined by RFC 821) to 2048, because there were problems with some AUTH
3203 commands, and RFC 1869 says the size should be increased for extended
3204 SMTP commands that take arguments.
3205
3206PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3207 Finch).
3208
3209PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an
3210 "unknown" error; now it says that the functionality isn't in the binary.

3212PH/10 Added a nasty fudge to try to recognize and flatten LDAP passwords in
3213 an address' error message when a string expansion fails (syntax or

PH
3214 whatever). Otherwise the password may appear in the log. Following change
3215 PH/42 below, there is no longer a chance of it appearing in a bounce
3216 message.

PH
3234PH/15 Further to TK/02 and TK/03 above, tidied up the tables of what conditions
3235 and controls are allowed in which ACLs. There were a couple of minor
3236 errors. Some of the entries in the conditions table (which is a table of
3237 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3238 negation of where the condition IS allowed.

PH
3242PH/17 The API for radiusclient changed at release 0.4.0. Unfortunately, the
3243 header file does not have a version number, so I've had to invent a new
3244 value for RADIUS_LIB_TYPE, namely "RADIUSCLIENTNEW" to request the new
3245 API. The code is untested by me (my Linux distribution still has 0.3.2 of
3246 radiusclient), but it was contributed by a Radius user.

901f42cb
PH
3251PH/19 When an Exim process that is running as root has to create an Exim log
3252 file, it does so in a subprocess that runs as exim:exim so as to get the
3253 ownership right at creation (otherwise, other Exim processes might see
3254 the file with the wrong ownership). There was no test for failure of this
3255 fork() call, which would lead to the process getting stuck as it waited
3256 for a non-existent subprocess. Forks do occasionally fail when resources
3257 run out. I reviewed all the other calls to fork(); they all seem to check
3258 for failure.

PH
3260PH/20 When checking for unexpected SMTP input at connect time (before writing
3261 the banner), Exim was not dealing correctly with a non-positive return
3262 from the read() function. If the client had disconnected by this time,
3263 the result was a log entry for a synchronization error with an empty
3264 string after "input=" when read() returned zero. If read() returned -1
3265 (an event I could not check), uninitialized data bytes were printed.
3266 There were reports of junk text (parts of files, etc) appearing after
3267 "input=".

3274PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then
3275 forgetting to use the resulting value; it was using the unexpanded value.
3276
c5ddb310
PH
3277PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3278 hadn't been configured. The fix is from Juergen Kreileder, who
3279 understands it better than I do:
3280
3281 "Here's what I see happening with three configured cyrus_sasl
3282 authenticators configured (plain, login, cram-md5):
3283
3284 On startup auth_cyrus_sasl_init() gets called for each of these.
3285 This means three calls to sasl_listmech() without a specified mech_list.
3286 => SASL tests which mechs of all available mechs actually work
3287 => three warnings about OTP not working
3288 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3289
3290 With the patch, sasl_listmech() also gets called three times. But now
3291 SASL's mech_list option is set to the server_mech specified in the the
3292 authenticator. Or in other words, the answer from sasl_listmech()
3293 gets limited to just the mech you're testing for (which is different
3294 for each call.)
3295 => the return list contains just 'plain' or 'login', 'cram-md5' or
3296 nothing depending on the value of ob->server_mech.
3297
3298 I've just tested the patch: Authentication still works fine,
3299 unavailable mechs specified in the exim configuration are still
3300 caught, and the auth.log warnings about OTP are gone."

PH
3310PH/27 $acl_verify_message is now set immediately after the failure of a
3311 verification in an ACL, and so is available in subsequent modifiers. In
3312 particular, the message can be preserved by coding like this:
3313
3314 warn !verify = sender
3315 set acl_m0 = $acl_verify_message
3316
3317 Previously, $acl_verify_message was set only while expanding "message"
3318 and "log_message" when a very denied access.

PH
3331PH/30 In these circumstances:
3332 . Two addresses routed to the same list of hosts;
3333 . First host does not offer TLS;
3334 . First host accepts first address;
3335 . First host gives temporary error to second address;
3336 . Second host offers TLS and a TLS session is established;
3337 . Second host accepts second address.
3338 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3339 and peerdn, if requested) that were in fact used only for the second
3340 address.

PH
3342PH/31 When doing a callout as part of verifying an address, Exim was not paying
3343 attention to any local part prefix or suffix that was matched by the
3344 router that accepted the address. It now behaves in the same way as it
3345 does for delivery: the affixes are removed from the local part unless
3346 rcpt_include_affixes is set on the transport.
