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

265TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
266
267 When a queue runner is handling a message, Exim first routes the
268 recipient addresses, during which it prunes them based on the retry
269 hints database. After that it attempts to deliver the message to
270 any remaining recipients. It then updates the hints database using
271 the retry rules.
272
273 So if a recipient address works intermittently, it can get repeatedly
274 deferred at routing time. The retry hints record remains fresh so the
275 address never reaches the final cutoff time.
276
277 This is a fairly common occurrence when a user is bumping up against
278 their storage quota. Exim had some logic in its local delivery code
279 to deal with this. However it did not apply to per-recipient defers
280 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
281
1ddeb334
TF
282 This change adds a proper retry rule check during routing so that the
283 final cutoff time is checked against the message's age. We only do
284 this check if there is an address retry record and there is not a
285 domain retry record; this implies that previous attempts to handle
286 the address had the retry_use_local_parts option turned on. We use
287 this as an approximation for the destination being like a local
288 delivery, as in LMTP.
67bd1ab3
TF
289
290 I suspect this new check makes the old local delivery cutoff check
291 redundant, but I have not verified this so I left the code in place.

295 Test 0254 submits a message to Exim with the header
296
297 Resent-From: f
298
299 When I ran the test suite under the user fanf2, Exim expanded
300 the header to contain my full name, whereas it should have added
301 a Resent-Sender: header. It erroneously treats any prefix of the
302 username as equal to the username.
303
304 This change corrects that bug.

325JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
326 Server implementation by Todd Lyons, client by JH.
327 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
328 config variable "prdr_enable" controls whether the server
329 advertises the facility. If the client requests PRDR a new
330 acl_data_smtp_prdr ACL is called once for each recipient, after
331 the body content is received and before the acl_smtp_data ACL.
332 The client is controlled by bolth of: a hosts_try_prdr option
333 on the smtp transport, and the server advertisement.
334 Default client logging of deliveries and rejections involving
335 PRDR are flagged with the string "PRDR".

613TF/03 Make the exiwhat support code safe for signals. Previously Exim might
614 lock up or crash if it happened to be inside a call to libc when it
615 got a SIGUSR1 from exiwhat.
616
617 The SIGUSR1 handler appends the current process status to the process
618 log which is later printed by exiwhat. It used to use the general
619 purpose logging code to do this, but several functions it calls are
620 not safe for signals.
621
622 The new output code in the SIGUSR1 handler is specific to the process
623 log, and simple enough that it's easy to inspect for signal safety.
624 Removing some special cases also simplifies the general logging code.
625 Removing the spurious timestamps from the process log simplifies
626 exiwhat.
627
c99ce5c9
TF
628TF/04 Improved ratelimit ACL condition.
629
630 The /noupdate option has been deprecated in favour of /readonly which
631 has clearer semantics. The /leaky, /strict, and /readonly update modes
632 are mutually exclusive. The update mode is no longer included in the
633 database key; it just determines when the database is updated. (This
634 means that when you upgrde Exim will forget old rate measurements.)
635
636 Exim now checks that the per_* options are used with an update mode that
637 makes sense for the current ACL. For example, when Exim is processing a
638 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
639 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
640 must specify per_mail/readonly. If you omit the update mode it defaults to
641 /leaky where that makes sense (as before) or /readonly where required.
642
643 The /noupdate option is now undocumented but still supported for
644 backwards compatibility. It is equivalent to /readonly except that in
645 ACLs where /readonly is required you may specify /leaky/noupdate or
646 /strict/noupdate which are treated the same as /readonly.
647
648 A useful new feature is the /count= option. This is a generalization
649 of the per_byte option, so that you can measure the throughput of other
650 aggregate values. For example, the per_byte option is now equivalent
651 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
652
653 The per_rcpt option has been generalized using the /count= mechanism
654 (though it's more complicated than the per_byte equivalence). When it is
655 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
656 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
657 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
658 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
659 Note that using per_rcpt with a non-readonly update mode in more than
660 one ACL will cause the recipients to be double-counted. (The per_mail
661 and per_byte options don't have this problem.)
662
663 The handling of very low rates has changed slightly. If the computed rate
664 is less than the event's count (usually one) then this event is the first
665 after a long gap. In this case the rate is set to the same as this event's
666 count, so that the first message of a spam run is counted properly.
667
668 The major new feature is a mechanism for counting the rate of unique
669 events. The new per_addr option counts the number of different
670 recipients that someone has sent messages to in the last time period. It
671 behaves like per_rcpt if all the recipient addresses are different, but
672 duplicate recipient addresses do not increase the measured rate. Like
673 the /count= option this is a general mechanism, so the per_addr option
674 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
675 example, measure the rate that a client uses different sender addresses
676 with the options per_mail/unique=$sender_address. There are further
677 details in the main documentation.

1227 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1228 were called 'true' and it seems that C99 defines that as a reserved
1229 keyword to be used with 'bool' variable types. That means you could
1230 not include C99-style headers which use bools without triggering
1231 build errors in sieve.c.

1249PH/01 Another patch from the Sieve maintainer.
1250
6a3bceb1
PH
1251PH/02 When an IPv6 address is converted to a string for single-key lookup
1252 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1253 dots are used instead of colons so that keys in lsearch files need not
1254 contain colons. This was done some time before quoting was made available
1255 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1256 (notated using the quote facility) so as to distinguish them from IPv4
1257 keys. This meant that lookups for IP addresses in host lists did not work
1258 for iplsearch lookups.
1259
1260 This has been fixed by arranging for IPv6 addresses to be expressed with
1261 colons if the lookup type is iplsearch. This is not incompatible, because
1262 previously such lookups could never work.
1263
1264 The situation is now rather anomolous, since one *can* have colons in
1265 ordinary lsearch keys. However, making the change in all cases is
1266 incompatible and would probably break a number of configurations.

MH
1271MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1272 conversion specification without a maximum field width, thereby enabling
1273 a rogue spamd server to cause a buffer overflow. While nobody in their
1274 right mind would setup Exim to query an untrusted spamd server, an
1275 attacker that gains access to a server running spamd could potentially
1276 exploit this vulnerability to run arbitrary code as the Exim user.

0f2cbd1b
MH
1281MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1282 a directory entry by the name of the lookup key. Previously, if a
1283 symlink pointed to a non-existing file or a file in a directory that
1284 Exim lacked permissions to read, a lookup for a key matching that
1285 symlink would fail. Now it is enough that a matching directory entry
1286 exists, symlink or not. (Bugzilla 503.)

1326PH/18 If a system quota error occurred while trying to create the file for

PH
1359PH/02 In an ACL statement such as
1360
1361 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1362
1363 if a client was not listed at all, or was listed with a value other than
1364 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1365 the condition was not true (as it should be), so access was not denied.
1366 The bug was that the ! inversion was incorrectly passed on to the second
1367 item. This has been fixed.

1391PH/07 There was a bug in the dovecot authenticator such that the value of

1400PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1401 run for batched SMTP input. It is now run at the start of every message
1402 in the batch. While fixing this I discovered that the process information
1403 (output by running exiwhat) was not always getting set for -bs and -bS
1404 input. This is fixed, and it now also says "batched" for BSMTP.

PH
1455PH/27 When a message times out after an over-quota error from an Exim-imposed
1456 quota, the bounce message says "mailbox is full". This message was not

0e20aff9
MH
1460MH/03 Made $recipients available in local_scan(). local_scan() already has
1461 better access to the recipient list through recipients_list[], but

ca86f471
PH
1464PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1465 in the case of a MAIL command with additional options following the

1467 were accidentally chopped off.
1468
a14e5636
PH
1469PH/29 SMTP synchronization checks are implemented when a command is read -
1470 there is a check that no more input is waiting when there shouldn't be
1471 any. However, for some commands, a delay in an ACL can mean that it is
1472 some time before the response is written. In this time, more input might
1473 arrive, invalidly. So now there are extra checks after an ACL has run for
1474 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1475 pipelining has not been advertised.

58c01c94
PH
1487PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1488 Exim which did not show up earlier: it was assuming that a call to
1489 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1490 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1491 was a macro that became an assignment, so it seemed to work. This has
1492 changed to a proper function call with a void return, hence the compile
1493 error. Exim's code has been fixed.

1504 "Completed" line in the log. When some messages of this type were

1509PH/38 The host_find_failed option in the manualroute router can now be set

1514PH/39 In a list of hosts for manualroute, if one item (either because of multi-

PH
1521PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1522 whoever called Exim into the -H file. In the case of the daemon it was
1523 behaving confusingly. When first started, it used values for whoever
1524 started the daemon, but after a SIGHUP it used the Exim user (because it
1525 calls itself on a restart). I have changed the code so that it now always
1526 uses the Exim user.

PH
1528PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a

1530 sender address), and a DATA command is nevertheless sent (as can happen
1531 with PIPELINING or a stupid MUA), the error message that was given to the
1532 RCPT commands is included in the rejection of the DATA command. This is
1533 intended to be helpful for MUAs that show only the final error to their
1534 users.

58eb016e 1548PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1549 the response to the final '.' that terminates a message, but only in the
1550 case where the client has not sent further data following the '.'
1551 (unfortunately, this is allowed). However, in many cases there won't be
1552 any further data because there won't be any more messages to send. A call
1553 to select() can be used: if it shows that the input is "ready", there is
1554 either input waiting, or the socket has been closed. An attempt to read
1555 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1556 would have sent an OK response which the client would never have see.

1567PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1568 fixed by 4.65/MH/01 (is this a record?) are fixed:
1569

1573 (ii) It is documented that the numeric comparison operators always treat
1574 their arguments as decimal numbers. This was broken in that numbers
1575 starting with 0 were being interpreted as octal.
1576
1577 While fixing these problems I realized that there was another issue that
1578 hadn't been noticed. Values of message_size_limit (both the global option
1579 and the transport option) were treated as octal if they started with 0.
1580 The documentation was vague. These values are now always treated as
1581 decimal, and I will make that clear in the documentation.

1598 large number of recipients for a single message is ridiculous
1599 (performance will be very, very poor), I have chosen to impose a limit

1606TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1607 leftover -K file (the existence of which was triggered by #402).

1623 in the field name.

PH
1625PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1626 callout verification, Exim cached a "reject" for the entire domain. This
1627 is correct for most verifications, but it is not correct for a recipient
1628 verification with use_sender or use_postmaster set, because in that case
1629 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1630 case of MAIL FROM:<> rejection from other early rejections (e.g.
1631 rejection of HELO). When verifying a recipient using a non-null MAIL
1632 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1633 Whatever the result of the callout, the value of the domain cache is
1634 left unchanged (for any other kind of callout, getting as far as trying
1635 RCPT means that the domain itself is ok).

1669PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1671 probably the interface on which it is arriving) and not to the outgoing
1672 callout (which could be using a different interface). This has been
1673 changed to use the value of the helo_data option from the smtp transport
1674 instead - this is what is used when a message is actually being sent. If
1675 there is no remote transport (possible with a router that sets up host
1676 addresses), $smtp_active_hostname is used.

7befa435 1679 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1680 (a) The code assumed that strncpy() returns a negative number on buffer
1681 overflow, which isn't the case. Replaced with Exim's string_format()
1682 function.
1683 (b) There were several signed/unsigned issues. I just did the minimum
1684 hacking in of casts. There is scope for a larger refactoring.
1685 (c) The code used strcasecmp() which is not a standard C function.
1686 Replaced with Exim's strcmpic() function.
1687 (d) The code set only $1; it now sets $auth1 as well.
1688 (e) A simple test gave the error "authentication client didn't specify
1689 service in request". It would seem that Dovecot has changed its
1690 interface. Fortunately there's a specification; I followed it and
1691 changed what the client sends and it appears to be working now.

1697 address A is aliased to B and C, where B exists and C does not. Without
1698 -v the output is "A verified" because verification stops after a
1699 successful redirection if more than one address is generated. However,
1700 with -v the child addresses are also verified. Exim was outputting "A
1701 failed to verify" and then showing the successful verification for C,
1702 with its parentage. It now outputs "B failed to verify", showing B's
1703 parentage before showing the successful verification of C.

1708
322050c2
PH
1709PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1710 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1711 they consult the DNS. I had assumed they would set it the way they
1712 wanted; and indeed my experiments on Linux seem to show that in some
1713 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1714 To be on the safe side, however, I have now made the interface to
1715 host_find_byname() similar to host_find_bydns(), with an argument
1716 containing the DNS resolver options. The host_find_byname() function now
1717 sets these options at its start, just as host_find_bydns() does. The smtp
1718 transport options dns_qualify_single and dns_search_parents are passed to
1719 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1720 of host_find_byname() use the default settings of RES_DEFNAMES
1721 (qualify_single) but not RES_DNSRCH (search_parents).

1723PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1724 spool_read_header() do less string testing, by means of a preliminary
1725 switch on the second character of optional "-foo" lines. (This is
1726 overdue, caused by the large number of possibilities that now exist.
1727 Originally there were few.) While I was there, I also converted the
1728 str(n)cmp tests so they don't re-test the leading "-" and the first
1729 character, in the hope this might squeeze out yet more improvement.

PH
1731PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1732 flag allowing group syntax was set by the header_syntax check but not
1733 turned off, possible causing trouble later; (2) The flag was not being
1734 set at all for the header_verify test, causing "group"-style headers to
1735 be rejected. I have now set it in this case, and also caused header_
1736 verify to ignore an empty address taken from a group. While doing this, I
1737 came across some other cases where the code for allowing group syntax
1738 while scanning a header line wasn't quite right (mostly, not resetting
1739 the flag correctly in the right place). These bugs could have caused
1740 trouble for malformed header lines. I hope it is now all correct.

PH
1742PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1743 with the "reply" argument non-NULL. The code, however (which originally
1744 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1745 but it didn't always do it. This confused somebody who was copying the
1746 code for some other use. I have removed all the tests.

PH
1748PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1749 feature that was used to support insecure browsers during the U.S. crypto
1750 embargo. It requires special client support, and Exim is probably the
1751 only MTA that supported it -- and would never use it because real RSA is
1752 always available. This code has been removed, because it had the bad
1753 effect of slowing Exim down by computing (never used) parameters for the
1754 RSA_EXPORT functionality.

PH
1756PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1757 authenticator to fail if there's a tab character in the incoming data
1758 (there should never be unless someone is messing about, as it's supposed
1759 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1760 if the connection is using TLS or if the remote IP is the same as the
1761 local IP, and the "valid-client-cert option" if a client certificate has
1762 been verified.

1793
1794PH/30 Exim was sometimes attempting to deliver messages that had suffered
1795 address errors (4xx response to RCPT) over the same connection as other
1796 messages routed to the same hosts. Such deliveries are always "forced",
1797 so retry times are not inspected. This resulted in far too many retries
1798 for the affected addresses. The effect occurred only when there were more
1799 hosts than the hosts_max_try setting in the smtp transport when it had
1800 the 4xx errors. Those hosts that it had tried were not added to the list
1801 of hosts for which the message was waiting, so if all were tried, there
1802 was no problem. Two fixes have been applied:
1803
1804 (i) If there are any address or message errors in an SMTP delivery, none
1805 of the hosts (tried or untried) are now added to the list of hosts
1806 for which the message is waiting, so the message should not be a
1807 candidate for sending over the same connection that was used for a
1808 successful delivery of some other message. This seems entirely
1809 reasonable: after all the message is NOT "waiting for some host".
1810 This is so "obvious" that I'm not sure why it wasn't done
1811 previously. Hope I haven't missed anything, but it can't do any
1812 harm, as the worst effect is to miss an optimization.
1813
1814 (ii) If, despite (i), such a delivery is accidentally attempted, the
1815 routing retry time is respected, so at least it doesn't keep
1816 hammering the server.

1831PH/35 The error "getsockname() failed: connection reset by peer" was being
1832 written to the panic log as well as the main log, but it isn't really
1833 panic-worthy as it just means the connection died rather early on. I have
1834 removed the panic log writing for the ECONNRESET error when getsockname()
1835 fails.
1836
48c7f9e2
PH
1837PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1838 runs only) independently of the message's sender address. This meant
1839 that, if the 4xx error was in fact related to the sender, a different
1840 message to the same recipient with a different sender could confuse
1841 things. In particualar, this can happen when sending to a greylisting
1842 server, but other circumstances could also provoke similar problems.
1843 I have changed the default so that the retry time for these errors is now
1844 based a combination of the sender and recipient addresses. This change
1845 can be overridden by setting address_retry_include_sender=false in the
1846 smtp transport.

2114PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2116 Unfortunately, if there is a major crisis, such as a disk failure,
2117 tcp-wrappers gives "deny", whereas what one would like would be some
2118 kind of temporary error. A kludge has been added to help with this.
2119 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2120 554 error is used if errno is still zero or contains ENOENT (which occurs
2121 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2122 451 error is used.

2158PH/01 The code for finding all the local interface addresses on a FreeBSD

2161 code found IPv4 interfaces correctly, but gave incorrect values for the
2162 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2163 that it would not match correctly against @[] and not recognize the IPv6
2164 addresses as local.

2207 autoreply, Exim could try to deliver to a non-existent relative file

2232 suitable debugging ouput when -d is set.

2243 Instead, it always explicitly searches for A/AAAA records. This avoids
2244 major problems that occur when a DNS server includes only records of one
2245 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2246 fixed another bug: if SRV records were looked up and the corresponding
2247 address records were *not* found in the additional section, the port
2248 values from the SRV records were lost.

2250PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

727071f8
PH
2258PH/19 When calculating a retry time, Exim used to measure the "time since
2259 failure" by looking at the "first failed" field in the retry record. Now
2260 it does not use this if it is later than than the arrival time of the
2261 message. Instead it uses the arrival time. This makes for better
2262 behaviour in cases where some deliveries succeed, thus re-setting the
2263 "first failed" field. An example is a quota failure for a huge message
2264 when small messages continue to be delivered. Without this change, the
2265 "time since failure" will always be short, possible causing more frequent
2266 delivery attempts for the huge message than are intended.

PH
2363PH/42 The content-scanning code uses fopen() to create files in which to put
2364 message data. Previously it was not paying any attention to the mode of
2365 the files. Exim runs with umask(0) because the rest of the code creates
2366 files with open(), and sets the required mode explicitly. Thus, these
2367 files were ending up world-writeable. This was not a big issue, because,
2368 being within the spool directory, they were not world-accessible. I have
2369 created a function called modefopen, which takes an additional mode
2370 argument. It sets umask(777), creates the file, chmods it to the required
2371 mode, then resets the umask. All the relevant calls to fopen() in the
2372 content scanning code have been changed to use this function.

2380PH/45 When the plaintext authenticator is running as a client, the server's
2381 challenges are checked to ensure they are valid base64 strings. By
2382 default, the authentication attempt is cancelled if an invalid string is
2383 received. Setting client_ignore_invalid_base64 true ignores these errors.
2384 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2385 they are received. Thus, the responses can be made to depend on the
2386 challenges. If an invalid string is ignored, an empty string is placed in
2387 the variable.

2407PH/52 Two bugs concerned with error handling when the smtp transport is
2408 used in LMTP mode:
2409
2410 (i) Exim was not creating retry information for temporary errors given
2411 for individual recipients after the DATA command when the smtp transport
2412 was used in LMTP mode. This meant that they could be retried too
2413 frequently, and not timed out correctly.
2414
2415 (ii) Exim was setting the flag that allows error details to be returned
2416 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2417 recipients that were returned after the DATA command.
2418
2419PH/53 This is related to PH/52, but is more general: for any failing address,
2420 when detailed error information was permitted to be returned to the
2421 sender, but the error was temporary, then after the final timeout, only
2422 "retry timeout exceeded" was returned. Now it returns the full error as
2423 well as "retry timeout exceeded".

2493PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2494 function verify_get_ident() calls ip_connect() to connect a socket, but
2495 if the "connect()" function timed out, ip_connect() used to close the
2496 socket. However, verify_get_ident() also closes the socket later, and in
2497 between Exim writes to the log, which may get opened at this point. When
2498 the socket was closed in ip_connect(), the log could get the same file
2499 descriptor number as the socket. This naturally causes chaos. The fix is
2500 not to close the socket in ip_connect(); the socket should be closed by
2501 the function that creates it. There was only one place in the code where
2502 this was missing, in the iplookup router, which I don't think anybody now
2503 uses, but I've fixed it anyway.

2526
2527 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2528 string.
2529
2530 (3) Reset the variables that are obtained from the first argument of
2531 ${prvscheck and used in the second argument before leaving the code,
2532 because their memory is reclaimed, so using them afterwards may do
2533 silly things.
2534
2535 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2536 one (it's much easier than Tom thought :-).

2559PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2560 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2561 not being looked up in the rDNS to get a host name, Exim was showing the
2562 IP address twice in Received: lines, even though the IP addresses were
2563 identical. For example:
2564
2565 Received: from [1.2.3.4] (helo=[1.2.3.4])
2566
2567 However, if the real host name was known, it was omitting the HELO data
2568 if it matched the actual IP address. This has been tidied up so that it
2569 doesn't show the same IP address twice.

2595PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2597
2598 Auto-submitted: auto-generated
2599
2600 in the messages that it generates (bounce messages and others, such as
2601 warnings). In the case of bounce messages for non-SMTP mesages, there was
2602 also a typo: it was using "Auto_submitted" (underscore instead of
2603 hyphen). Since every message generated by Exim is necessarily in response
2604 to another message, thes have all been changed to:
2605
2606 Auto-Submitted: auto-replied
2607
2608 in accordance with these statements in the RFC:
2609
2610 The auto-replied keyword:
2611
2612 - SHOULD be used on messages sent in direct response to another
2613 message by an automatic process,
2614
2615 - MUST NOT be used on manually-generated messages,

2617 - MAY be used on Delivery Status Notifications (DSNs) and Message
2618 Disposition Notifications (MDNs),

2661 addresses acquired from the DNS when checking that the found name did
2662 have the original IP as one of its addresses. Since any found IPv6
2663 addresses are likely to be in abbreviated form, the comparison could
2664 fail. Luckily, there already exists a function for doing the comparison
2665 by converting both addresses to binary, so now that is used instead of
2666 the text comparison.

2964 with the definition in sysexits.h (which is #included earlier).
2965 Fortunately, Exim does not actually use EX_OK. The code used to try to
2966 preserve the sysexits.h value, by assumimg that macro definitions were
2967 scanned for macro replacements. I have been disabused of this notion,
2968 so now the code just undefines EX_OK before #including unistd.h.

2973 This seems wrong - if the receiver was accepting one byte at a time it
2974 would take for ever. The timeout is now adjusted when this happens. It
2975 doesn't have to be particularly precise.

3150 spool, instead of being failed because of the mua_wrapper setting. This
3151 is now fixed, and I tidied up some of the mua_wrapper messages at the
3152 same time.

3154SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3181PH/01 Installed a patch from the Sieve maintainer that allows -bf to be used
3182 to test Sieve filters that use "vacation".
3183
3184PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3185 that changes the way the GnuTLS parameters are stored in the cache file.
3186 The new format can be generated externally. For backward compatibility,
3187 if the data in the cache doesn't make sense, Exim assumes it has read an
3188 old-format file, and it generates new data and writes a new file. This
3189 means that you can't go back to an older release without removing the
3190 file.
3191
3192PH/03 A redirect router that has both "unseen" and "one_time" set does not
3193 work if there are any delivery delays because "one_time" forces the
3194 parent to be marked "delivered", so its unseen clone is never tried
3195 again. For this reason, Exim now forbids the simultaneous setting of
3196 these two options.
3197
3198PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3199 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3200 entry if you want to know the details. The fix, however, neglected to
3201 consider the case when local delivery batching is involved. The test for
3202 "previously delivered" was not happening when checking to see if an
3203 address could be batched with a previous (undelivered) one; under
3204 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3205 address.

3206
3207PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3208 in its include files, and this causes problems building Exim.
3209
3210PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3211 header_syntax) but Exim was just ignoring anything given after a slash.
3212 In particular, this caused confusion with an attempt to use "verify =
3213 reverse_host_lookup/defer_ok". An error is now given when options are
3214 supplied for verify items that do not have them. (Maybe reverse_host_
3215 lookup should have a defer_ok option, but that's a different point.)
3216
3217PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3218 defined by RFC 821) to 2048, because there were problems with some AUTH

3220 SMTP commands that take arguments.

3253 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3254 negation of where the condition IS allowed.

PH
3267PH/19 When an Exim process that is running as root has to create an Exim log
3268 file, it does so in a subprocess that runs as exim:exim so as to get the
3269 ownership right at creation (otherwise, other Exim processes might see
3270 the file with the wrong ownership). There was no test for failure of this
3271 fork() call, which would lead to the process getting stuck as it waited
3272 for a non-existent subprocess. Forks do occasionally fail when resources
3273 run out. I reviewed all the other calls to fork(); they all seem to check
3274 for failure.

3276PH/20 When checking for unexpected SMTP input at connect time (before writing
3277 the banner), Exim was not dealing correctly with a non-positive return
3278 from the read() function. If the client had disconnected by this time,
3279 the result was a log entry for a synchronization error with an empty
3280 string after "input=" when read() returned zero. If read() returned -1
3281 (an event I could not check), uninitialized data bytes were printed.
3282 There were reports of junk text (parts of files, etc) appearing after
3283 "input=".

3292
c5ddb310
PH
3293PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3294 hadn't been configured. The fix is from Juergen Kreileder, who
3295 understands it better than I do:
3296
3297 "Here's what I see happening with three configured cyrus_sasl
3298 authenticators configured (plain, login, cram-md5):
3299
3300 On startup auth_cyrus_sasl_init() gets called for each of these.
3301 This means three calls to sasl_listmech() without a specified mech_list.
3302 => SASL tests which mechs of all available mechs actually work
3303 => three warnings about OTP not working
3304 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3305
3306 With the patch, sasl_listmech() also gets called three times. But now
3307 SASL's mech_list option is set to the server_mech specified in the the
3308 authenticator. Or in other words, the answer from sasl_listmech()
3309 gets limited to just the mech you're testing for (which is different
3310 for each call.)
3311 => the return list contains just 'plain' or 'login', 'cram-md5' or
3312 nothing depending on the value of ob->server_mech.
3313
3314 I've just tested the patch: Authentication still works fine,
3315 unavailable mechs specified in the exim configuration are still
3316 caught, and the auth.log warnings about OTP are gone."

3326PH/27 $acl_verify_message is now set immediately after the failure of a

3331 set acl_m0 = $acl_verify_message

3352 . Second host offers TLS and a TLS session is established;
