6-----------------
7TL/01 When running the test suite, the README says that variables such as
8 no_msglog_check are global and can be placed anywhere in a specific
9 test's script, however it was observed that placement needed to be near
10 the beginning for it to behave that way. Changed the runtest perl
11 script to read through the entire script once to detect and set these
12 variables, reset to the beginning of the script, and then run through
13 the script parsing/test process like normal.

15TL/02 The BSD's have an arc4random API. One of the functions to induce
16 adding randomness was arc4random_stir(), but it has been removed in

18 function when detected.

23TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
24 syntax errors in an expansion can be treated as a string instead of
25 logging or causing an error, due to the internal use of bool_lax

47Exim version 4.83
48-----------------
49
50TF/01 Correctly close the server side of TLS when forking for delivery.
51
52 When a message was received over SMTP with TLS, Exim failed to clear up
53 the incoming connection properly after forking off the child process to
54 deliver the message. In some situations the subsequent outgoing
55 delivery connection happened to have the same fd number as the incoming
56 connection previously had. Exim would try to use TLS and fail, logging
57 a "Bad file descriptor" error.

303TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
304
305 When a queue runner is handling a message, Exim first routes the
306 recipient addresses, during which it prunes them based on the retry
307 hints database. After that it attempts to deliver the message to
308 any remaining recipients. It then updates the hints database using
309 the retry rules.
310
311 So if a recipient address works intermittently, it can get repeatedly
312 deferred at routing time. The retry hints record remains fresh so the
313 address never reaches the final cutoff time.
314
315 This is a fairly common occurrence when a user is bumping up against
316 their storage quota. Exim had some logic in its local delivery code
317 to deal with this. However it did not apply to per-recipient defers
318 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
319
1ddeb334
TF
320 This change adds a proper retry rule check during routing so that the
321 final cutoff time is checked against the message's age. We only do
322 this check if there is an address retry record and there is not a
323 domain retry record; this implies that previous attempts to handle
324 the address had the retry_use_local_parts option turned on. We use
325 this as an approximation for the destination being like a local
326 delivery, as in LMTP.
67bd1ab3
TF
327
328 I suspect this new check makes the old local delivery cutoff check
329 redundant, but I have not verified this so I left the code in place.

336
337 When I ran the test suite under the user fanf2, Exim expanded
338 the header to contain my full name, whereas it should have added
339 a Resent-Sender: header. It erroneously treats any prefix of the
340 username as equal to the username.

363JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
364 Server implementation by Todd Lyons, client by JH.
365 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
366 config variable "prdr_enable" controls whether the server
367 advertises the facility. If the client requests PRDR a new
368 acl_data_smtp_prdr ACL is called once for each recipient, after
369 the body content is received and before the acl_smtp_data ACL.
370 The client is controlled by bolth of: a hosts_try_prdr option
371 on the smtp transport, and the server advertisement.
372 Default client logging of deliveries and rejections involving
373 PRDR are flagged with the string "PRDR".

651TF/03 Make the exiwhat support code safe for signals. Previously Exim might
652 lock up or crash if it happened to be inside a call to libc when it
653 got a SIGUSR1 from exiwhat.
654
655 The SIGUSR1 handler appends the current process status to the process
656 log which is later printed by exiwhat. It used to use the general
657 purpose logging code to do this, but several functions it calls are
658 not safe for signals.
659
660 The new output code in the SIGUSR1 handler is specific to the process
661 log, and simple enough that it's easy to inspect for signal safety.
662 Removing some special cases also simplifies the general logging code.
663 Removing the spurious timestamps from the process log simplifies
664 exiwhat.
665
c99ce5c9
TF
666TF/04 Improved ratelimit ACL condition.
667
668 The /noupdate option has been deprecated in favour of /readonly which
669 has clearer semantics. The /leaky, /strict, and /readonly update modes
670 are mutually exclusive. The update mode is no longer included in the
671 database key; it just determines when the database is updated. (This
672 means that when you upgrde Exim will forget old rate measurements.)
673
674 Exim now checks that the per_* options are used with an update mode that
675 makes sense for the current ACL. For example, when Exim is processing a
676 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
677 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
678 must specify per_mail/readonly. If you omit the update mode it defaults to
679 /leaky where that makes sense (as before) or /readonly where required.
680
681 The /noupdate option is now undocumented but still supported for
682 backwards compatibility. It is equivalent to /readonly except that in
683 ACLs where /readonly is required you may specify /leaky/noupdate or
684 /strict/noupdate which are treated the same as /readonly.
685
686 A useful new feature is the /count= option. This is a generalization
687 of the per_byte option, so that you can measure the throughput of other
688 aggregate values. For example, the per_byte option is now equivalent
689 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
690
691 The per_rcpt option has been generalized using the /count= mechanism
692 (though it's more complicated than the per_byte equivalence). When it is
693 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
694 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
695 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
696 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
697 Note that using per_rcpt with a non-readonly update mode in more than
698 one ACL will cause the recipients to be double-counted. (The per_mail
699 and per_byte options don't have this problem.)
700
701 The handling of very low rates has changed slightly. If the computed rate
702 is less than the event's count (usually one) then this event is the first
703 after a long gap. In this case the rate is set to the same as this event's
704 count, so that the first message of a spam run is counted properly.
705
706 The major new feature is a mechanism for counting the rate of unique
707 events. The new per_addr option counts the number of different
708 recipients that someone has sent messages to in the last time period. It
709 behaves like per_rcpt if all the recipient addresses are different, but
710 duplicate recipient addresses do not increase the measured rate. Like
711 the /count= option this is a general mechanism, so the per_addr option
712 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
713 example, measure the rate that a client uses different sender addresses
714 with the options per_mail/unique=$sender_address. There are further
715 details in the main documentation.

1265 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1266 were called 'true' and it seems that C99 defines that as a reserved

1268 not include C99-style headers which use bools without triggering
1269 build errors in sieve.c.

1285-----------------
1286
1287PH/01 Another patch from the Sieve maintainer.
1288
6a3bceb1
PH
1289PH/02 When an IPv6 address is converted to a string for single-key lookup
1290 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1291 dots are used instead of colons so that keys in lsearch files need not
1292 contain colons. This was done some time before quoting was made available
1293 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1294 (notated using the quote facility) so as to distinguish them from IPv4
1295 keys. This meant that lookups for IP addresses in host lists did not work
1296 for iplsearch lookups.
1297
1298 This has been fixed by arranging for IPv6 addresses to be expressed with
1299 colons if the lookup type is iplsearch. This is not incompatible, because
1300 previously such lookups could never work.
1301
1302 The situation is now rather anomolous, since one *can* have colons in
1303 ordinary lsearch keys. However, making the change in all cases is
1304 incompatible and would probably break a number of configurations.

MH
1309MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1310 conversion specification without a maximum field width, thereby enabling
1311 a rogue spamd server to cause a buffer overflow. While nobody in their
1312 right mind would setup Exim to query an untrusted spamd server, an
1313 attacker that gains access to a server running spamd could potentially
1314 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1319MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1320 a directory entry by the name of the lookup key. Previously, if a
1321 symlink pointed to a non-existing file or a file in a directory that
1322 Exim lacked permissions to read, a lookup for a key matching that
1323 symlink would fail. Now it is enough that a matching directory entry
1324 exists, symlink or not. (Bugzilla 503.)

1397PH/02 In an ACL statement such as

1401 if a client was not listed at all, or was listed with a value other than
1402 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1403 the condition was not true (as it should be), so access was not denied.

PH
1507PH/29 SMTP synchronization checks are implemented when a command is read -
1508 there is a check that no more input is waiting when there shouldn't be
1509 any. However, for some commands, a delay in an ACL can mean that it is
1510 some time before the response is written. In this time, more input might
1511 arrive, invalidly. So now there are extra checks after an ACL has run for
1512 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1513 pipelining has not been advertised.

PH
1525PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1526 Exim which did not show up earlier: it was assuming that a call to
1527 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1528 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1529 was a macro that became an assignment, so it seemed to work. This has
1530 changed to a proper function call with a void return, hence the compile
1531 error. Exim's code has been fixed.

1562 started the daemon, but after a SIGHUP it used the Exim user (because it

1569 with PIPELINING or a stupid MUA), the error message that was given to the
1570 RCPT commands is included in the rejection of the DATA command. This is

58eb016e 1586PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1587 the response to the final '.' that terminates a message, but only in the
1588 case where the client has not sent further data following the '.'
1589 (unfortunately, this is allowed). However, in many cases there won't be
1590 any further data because there won't be any more messages to send. A call
1591 to select() can be used: if it shows that the input is "ready", there is
1592 either input waiting, or the socket has been closed. An attempt to read
1593 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1594 would have sent an OK response which the client would never have see.

1602Exim version 4.66
1603-----------------
1604
1605PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1606 fixed by 4.65/MH/01 (is this a record?) are fixed:
1607
1608 (i) An empty string was always treated as zero by the numeric comparison
1609 operators. This behaviour has been restored.
1610
1611 (ii) It is documented that the numeric comparison operators always treat
1612 their arguments as decimal numbers. This was broken in that numbers
1613 starting with 0 were being interpreted as octal.
1614
1615 While fixing these problems I realized that there was another issue that
1616 hadn't been noticed. Values of message_size_limit (both the global option
1617 and the transport option) were treated as octal if they started with 0.
1618 The documentation was vague. These values are now always treated as
1619 decimal, and I will make that clear in the documentation.

1633PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1634 child addresses, Exim now panics and dies. Previously, because the count
1635 is held in a short int, deliveries were likely to be lost. As such a
1636 large number of recipients for a single message is ridiculous
1637 (performance will be very, very poor), I have chosen to impose a limit
1638 rather than extend the field.

1644TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1645 leftover -K file (the existence of which was triggered by #402).
1646 While we were at it, introduced process PID as part of the -K
1647 filename. This should rule out race conditions when creating
1648 these files.

1650TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1651 processing considerably. Previous code took too long for large mails,
1652 triggering a timeout which in turn triggers #401.
1653
1654TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1655 in the DK code in transports.c. sendfile() is not really portable,
1656 hence the _LINUX specificness.

1658TF/01 In the add_headers option to the mail command in an Exim filter,

1661 in the field name.

2b1c6e3a
PH
1663PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1664 callout verification, Exim cached a "reject" for the entire domain. This
1665 is correct for most verifications, but it is not correct for a recipient
1666 verification with use_sender or use_postmaster set, because in that case
1667 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1668 case of MAIL FROM:<> rejection from other early rejections (e.g.
1669 rejection of HELO). When verifying a recipient using a non-null MAIL
1670 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1671 Whatever the result of the callout, the value of the domain cache is
1672 left unchanged (for any other kind of callout, getting as far as trying
1673 RCPT means that the domain itself is ok).

1707PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1708 hostname. This is wrong, because it relates to the incoming message (and
1709 probably the interface on which it is arriving) and not to the outgoing
1710 callout (which could be using a different interface). This has been
1711 changed to use the value of the helo_data option from the smtp transport
1712 instead - this is what is used when a message is actually being sent. If
1713 there is no remote transport (possible with a router that sets up host
1714 addresses), $smtp_active_hostname is used.

14aa5a05 1716PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1717 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1718 (a) The code assumed that strncpy() returns a negative number on buffer
1719 overflow, which isn't the case. Replaced with Exim's string_format()
1720 function.
1721 (b) There were several signed/unsigned issues. I just did the minimum
1722 hacking in of casts. There is scope for a larger refactoring.
1723 (c) The code used strcasecmp() which is not a standard C function.
1724 Replaced with Exim's strcmpic() function.
1725 (d) The code set only $1; it now sets $auth1 as well.
1726 (e) A simple test gave the error "authentication client didn't specify
1727 service in request". It would seem that Dovecot has changed its
1728 interface. Fortunately there's a specification; I followed it and
1729 changed what the client sends and it appears to be working now.

1734PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1735 address A is aliased to B and C, where B exists and C does not. Without
1736 -v the output is "A verified" because verification stops after a
1737 successful redirection if more than one address is generated. However,
1738 with -v the child addresses are also verified. Exim was outputting "A
1739 failed to verify" and then showing the successful verification for C,
1740 with its parentage. It now outputs "B failed to verify", showing B's
1741 parentage before showing the successful verification of C.

1744 look up a TXT record in a specific list after matching in a combined
1745 list.
1746
322050c2
PH
1747PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1748 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1749 they consult the DNS. I had assumed they would set it the way they
1750 wanted; and indeed my experiments on Linux seem to show that in some
1751 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1752 To be on the safe side, however, I have now made the interface to
1753 host_find_byname() similar to host_find_bydns(), with an argument
1754 containing the DNS resolver options. The host_find_byname() function now
1755 sets these options at its start, just as host_find_bydns() does. The smtp
1756 transport options dns_qualify_single and dns_search_parents are passed to
1757 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1758 of host_find_byname() use the default settings of RES_DEFNAMES
1759 (qualify_single) but not RES_DNSRCH (search_parents).

1761PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1762 spool_read_header() do less string testing, by means of a preliminary
1763 switch on the second character of optional "-foo" lines. (This is
1764 overdue, caused by the large number of possibilities that now exist.
1765 Originally there were few.) While I was there, I also converted the
1766 str(n)cmp tests so they don't re-test the leading "-" and the first
1767 character, in the hope this might squeeze out yet more improvement.

PH
1769PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1770 flag allowing group syntax was set by the header_syntax check but not
1771 turned off, possible causing trouble later; (2) The flag was not being
1772 set at all for the header_verify test, causing "group"-style headers to
1773 be rejected. I have now set it in this case, and also caused header_
1774 verify to ignore an empty address taken from a group. While doing this, I
1775 came across some other cases where the code for allowing group syntax
1776 while scanning a header line wasn't quite right (mostly, not resetting
1777 the flag correctly in the right place). These bugs could have caused
1778 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1780PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1781 with the "reply" argument non-NULL. The code, however (which originally
1782 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1783 but it didn't always do it. This confused somebody who was copying the
1784 code for some other use. I have removed all the tests.

411ef850
PH
1786PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1787 feature that was used to support insecure browsers during the U.S. crypto
1788 embargo. It requires special client support, and Exim is probably the
1789 only MTA that supported it -- and would never use it because real RSA is
1790 always available. This code has been removed, because it had the bad
1791 effect of slowing Exim down by computing (never used) parameters for the
1792 RSA_EXPORT functionality.
1793
7befa435
PH
1794PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1795 authenticator to fail if there's a tab character in the incoming data
1796 (there should never be unless someone is messing about, as it's supposed
1797 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1798 if the connection is using TLS or if the remote IP is the same as the
1799 local IP, and the "valid-client-cert option" if a client certificate has
1800 been verified.

PH
1831
1832PH/30 Exim was sometimes attempting to deliver messages that had suffered
1833 address errors (4xx response to RCPT) over the same connection as other
1834 messages routed to the same hosts. Such deliveries are always "forced",
1835 so retry times are not inspected. This resulted in far too many retries
1836 for the affected addresses. The effect occurred only when there were more
1837 hosts than the hosts_max_try setting in the smtp transport when it had
1838 the 4xx errors. Those hosts that it had tried were not added to the list
1839 of hosts for which the message was waiting, so if all were tried, there
1840 was no problem. Two fixes have been applied:
1841
1842 (i) If there are any address or message errors in an SMTP delivery, none
1843 of the hosts (tried or untried) are now added to the list of hosts
1844 for which the message is waiting, so the message should not be a
1845 candidate for sending over the same connection that was used for a
1846 successful delivery of some other message. This seems entirely
1847 reasonable: after all the message is NOT "waiting for some host".
1848 This is so "obvious" that I'm not sure why it wasn't done
1849 previously. Hope I haven't missed anything, but it can't do any
1850 harm, as the worst effect is to miss an optimization.
1851
1852 (ii) If, despite (i), such a delivery is accidentally attempted, the
1853 routing retry time is respected, so at least it doesn't keep
1854 hammering the server.

PH
1869PH/35 The error "getsockname() failed: connection reset by peer" was being
1870 written to the panic log as well as the main log, but it isn't really
1871 panic-worthy as it just means the connection died rather early on. I have
1872 removed the panic log writing for the ECONNRESET error when getsockname()
1873 fails.
1874
48c7f9e2
PH
1875PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1876 runs only) independently of the message's sender address. This meant
1877 that, if the 4xx error was in fact related to the sender, a different
1878 message to the same recipient with a different sender could confuse
1879 things. In particualar, this can happen when sending to a greylisting
1880 server, but other circumstances could also provoke similar problems.
1881 I have changed the default so that the retry time for these errors is now
1882 based a combination of the sender and recipient addresses. This change
1883 can be overridden by setting address_retry_include_sender=false in the
1884 smtp transport.

2152PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2154 Unfortunately, if there is a major crisis, such as a disk failure,
2155 tcp-wrappers gives "deny", whereas what one would like would be some
2156 kind of temporary error. A kludge has been added to help with this.
2157 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2158 554 error is used if errno is still zero or contains ENOENT (which occurs
2159 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2200 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2245 autoreply, Exim could try to deliver to a non-existent relative file

2270 suitable debugging ouput when -d is set.

2280 additional section of a DNS packet that returns MX or SRV records.
2281 Instead, it always explicitly searches for A/AAAA records. This avoids
2282 major problems that occur when a DNS server includes only records of one
2283 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2284 fixed another bug: if SRV records were looked up and the corresponding
2285 address records were *not* found in the additional section, the port
2286 values from the SRV records were lost.

2288PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2296PH/19 When calculating a retry time, Exim used to measure the "time since
2297 failure" by looking at the "first failed" field in the retry record. Now
2298 it does not use this if it is later than than the arrival time of the
2299 message. Instead it uses the arrival time. This makes for better
2300 behaviour in cases where some deliveries succeed, thus re-setting the
2301 "first failed" field. An example is a quota failure for a huge message
2302 when small messages continue to be delivered. Without this change, the
2303 "time since failure" will always be short, possible causing more frequent
2304 delivery attempts for the huge message than are intended.

PH
2401PH/42 The content-scanning code uses fopen() to create files in which to put
2402 message data. Previously it was not paying any attention to the mode of
2403 the files. Exim runs with umask(0) because the rest of the code creates
2404 files with open(), and sets the required mode explicitly. Thus, these
2405 files were ending up world-writeable. This was not a big issue, because,
2406 being within the spool directory, they were not world-accessible. I have
2407 created a function called modefopen, which takes an additional mode
2408 argument. It sets umask(777), creates the file, chmods it to the required
2409 mode, then resets the umask. All the relevant calls to fopen() in the
2410 content scanning code have been changed to use this function.

2418PH/45 When the plaintext authenticator is running as a client, the server's
2419 challenges are checked to ensure they are valid base64 strings. By
2420 default, the authentication attempt is cancelled if an invalid string is
2421 received. Setting client_ignore_invalid_base64 true ignores these errors.
2422 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2423 they are received. Thus, the responses can be made to depend on the
2424 challenges. If an invalid string is ignored, an empty string is placed in
2425 the variable.

2439 of files (along with the size), even though it did not need this
2440 information. It now does the scan only if it needs to find either the

PH
2445PH/52 Two bugs concerned with error handling when the smtp transport is
2446 used in LMTP mode:
2447
2448 (i) Exim was not creating retry information for temporary errors given
2449 for individual recipients after the DATA command when the smtp transport
2450 was used in LMTP mode. This meant that they could be retried too
2451 frequently, and not timed out correctly.
2452
2453 (ii) Exim was setting the flag that allows error details to be returned
2454 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2455 recipients that were returned after the DATA command.
2456
2457PH/53 This is related to PH/52, but is more general: for any failing address,
2458 when detailed error information was permitted to be returned to the
2459 sender, but the error was temporary, then after the final timeout, only
2460 "retry timeout exceeded" was returned. Now it returns the full error as
2461 well as "retry timeout exceeded".

2517PH/68 The bounce_return_message and bounce_return_body options were not being

2519 In particular, this applied to messages rejected by the ACL. This bug has
2520 been fixed. However, if bounce_return_message is true and bounce_return_
2521 body is false, the headers that are returned for a non-SMTP message
2522 include only those that have been read before the error was detected.

PH
2531PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2532 function verify_get_ident() calls ip_connect() to connect a socket, but
2533 if the "connect()" function timed out, ip_connect() used to close the
2534 socket. However, verify_get_ident() also closes the socket later, and in
2535 between Exim writes to the log, which may get opened at this point. When
2536 the socket was closed in ip_connect(), the log could get the same file
2537 descriptor number as the socket. This naturally causes chaos. The fix is
2538 not to close the socket in ip_connect(); the socket should be closed by
2539 the function that creates it. There was only one place in the code where
2540 this was missing, in the iplookup router, which I don't think anybody now
2541 uses, but I've fixed it anyway.

2560PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2561
2562 (1) Generate an error if the third argument for the ${prvs expansion is
2563 not a single digit.
2564
2565 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2566 string.
2567
2568 (3) Reset the variables that are obtained from the first argument of
2569 ${prvscheck and used in the second argument before leaving the code,
2570 because their memory is reclaimed, so using them afterwards may do
2571 silly things.
2572
2573 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2574 one (it's much easier than Tom thought :-).
2575
2576 (5) Because of (4), we can now allow for the use of $prvscheck_result
2577 inside the third argument.

2588
2589 => >A.N.Other <ano@some.domain> <original@ddress> ...
2590
2591 This has been changed so that it extracts the operative address. There
2592 may be more than one such address. If so, they are comma-separated, like
2593 this:

PH
2597PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2598 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2599 not being looked up in the rDNS to get a host name, Exim was showing the
2600 IP address twice in Received: lines, even though the IP addresses were
2601 identical. For example:
2602
2603 Received: from [1.2.3.4] (helo=[1.2.3.4])
2604
2605 However, if the real host name was known, it was omitting the HELO data
2606 if it matched the actual IP address. This has been tidied up so that it
2607 doesn't show the same IP address twice.

2609PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2633PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2634 Electronic Mail") by including:
2635
2636 Auto-submitted: auto-generated
2637
2638 in the messages that it generates (bounce messages and others, such as
2639 warnings). In the case of bounce messages for non-SMTP mesages, there was
2640 also a typo: it was using "Auto_submitted" (underscore instead of
2641 hyphen). Since every message generated by Exim is necessarily in response
2642 to another message, thes have all been changed to:
2643
2644 Auto-Submitted: auto-replied
2645
2646 in accordance with these statements in the RFC:
2647
2648 The auto-replied keyword:
2649
2650 - SHOULD be used on messages sent in direct response to another
2651 message by an automatic process,
2652

2696PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2697 canonical form (as documented). However, after a host name lookup from
2698 the IP address, check_host() was doing a simple string comparison with
2699 addresses acquired from the DNS when checking that the found name did
2700 have the original IP as one of its addresses. Since any found IPv6
2701 addresses are likely to be in abbreviated form, the comparison could
2702 fail. Luckily, there already exists a function for doing the comparison
2703 by converting both addresses to binary, so now that is used instead of
2704 the text comparison.

3002 with the definition in sysexits.h (which is #included earlier).
3003 Fortunately, Exim does not actually use EX_OK. The code used to try to
3004 preserve the sysexits.h value, by assumimg that macro definitions were
3005 scanned for macro replacements. I have been disabused of this notion,
3006 so now the code just undefines EX_OK before #including unistd.h.

3011 This seems wrong - if the receiver was accepting one byte at a time it
3012 would take for ever. The timeout is now adjusted when this happens. It
3013 doesn't have to be particularly precise.

3150 specify a transport. However, if an address that was verified by such a
3151 router was the subject of a callout, Exim crashed because it tried to
3152 read the rcpt_include_affixes from the non-existent transport. Now it
3153 just assumes that the setting of that option is false. This bug was
3154 introduced by 4.51/PH/31.

3164PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3165 aren't the modern standard, and it seems that some systems' include files
3166 don't always have them. Exim was already checking for some of the newer
3167 ones like T_AAAA, and defining it itself. I've added checks for all the
3168 record types that Exim uses.

3170PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3171 not automatically generating a new one, as it is supposed to. This
3172 prevented TLS from working. If the file did exist, but contained invalid
3173 data, a new version was generated, as expected. It was only the case of a
3174 non-existent file that was broken.

3185PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3186 the use of a port name that isn't defined in /etc/services) occurred, the
3187 message was deferred as in a normal delivery, and thus remained on the
3188 spool, instead of being failed because of the mua_wrapper setting. This
3189 is now fixed, and I tidied up some of the mua_wrapper messages at the
3190 same time.

3192SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3221
3222PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3223 that changes the way the GnuTLS parameters are stored in the cache file.
3224 The new format can be generated externally. For backward compatibility,
3225 if the data in the cache doesn't make sense, Exim assumes it has read an
3226 old-format file, and it generates new data and writes a new file. This
3227 means that you can't go back to an older release without removing the
3228 file.
3229
3230PH/03 A redirect router that has both "unseen" and "one_time" set does not
3231 work if there are any delivery delays because "one_time" forces the
3232 parent to be marked "delivered", so its unseen clone is never tried
3233 again. For this reason, Exim now forbids the simultaneous setting of
3234 these two options.
3235
3236PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3237 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3238 entry if you want to know the details. The fix, however, neglected to
3239 consider the case when local delivery batching is involved. The test for
3240 "previously delivered" was not happening when checking to see if an
3241 address could be batched with a previous (undelivered) one; under
3242 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3243 address.

PH
3244
3245PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3246 in its include files, and this causes problems building Exim.
3247
3248PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3249 header_syntax) but Exim was just ignoring anything given after a slash.
3250 In particular, this caused confusion with an attempt to use "verify =
3251 reverse_host_lookup/defer_ok". An error is now given when options are
3252 supplied for verify items that do not have them. (Maybe reverse_host_
3253 lookup should have a defer_ok option, but that's a different point.)
3254
3255PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3256 defined by RFC 821) to 2048, because there were problems with some AUTH
3257 commands, and RFC 1869 says the size should be increased for extended
3258 SMTP commands that take arguments.

3291 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3292 negation of where the condition IS allowed.

PH
3305PH/19 When an Exim process that is running as root has to create an Exim log
3306 file, it does so in a subprocess that runs as exim:exim so as to get the
3307 ownership right at creation (otherwise, other Exim processes might see
3308 the file with the wrong ownership). There was no test for failure of this
3309 fork() call, which would lead to the process getting stuck as it waited
3310 for a non-existent subprocess. Forks do occasionally fail when resources
3311 run out. I reviewed all the other calls to fork(); they all seem to check
3312 for failure.

3314PH/20 When checking for unexpected SMTP input at connect time (before writing
3315 the banner), Exim was not dealing correctly with a non-positive return
3316 from the read() function. If the client had disconnected by this time,
3317 the result was a log entry for a synchronization error with an empty
3318 string after "input=" when read() returned zero. If read() returned -1
3319 (an event I could not check), uninitialized data bytes were printed.

3321 "input=".

3330
c5ddb310
PH
3331PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3332 hadn't been configured. The fix is from Juergen Kreileder, who
3333 understands it better than I do:
3334
3335 "Here's what I see happening with three configured cyrus_sasl
3336 authenticators configured (plain, login, cram-md5):
3337
3338 On startup auth_cyrus_sasl_init() gets called for each of these.
3339 This means three calls to sasl_listmech() without a specified mech_list.
3340 => SASL tests which mechs of all available mechs actually work
3341 => three warnings about OTP not working
3342 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3343
3344 With the patch, sasl_listmech() also gets called three times. But now
3345 SASL's mech_list option is set to the server_mech specified in the the
3346 authenticator. Or in other words, the answer from sasl_listmech()
3347 gets limited to just the mech you're testing for (which is different
3348 for each call.)
3349 => the return list contains just 'plain' or 'login', 'cram-md5' or
3350 nothing depending on the value of ob->server_mech.
3351
3352 I've just tested the patch: Authentication still works fine,
3353 unavailable mechs specified in the exim configuration are still
3354 caught, and the auth.log warnings about OTP are gone."
