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.

197TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
198
199 When a queue runner is handling a message, Exim first routes the
200 recipient addresses, during which it prunes them based on the retry
201 hints database. After that it attempts to deliver the message to
202 any remaining recipients. It then updates the hints database using
203 the retry rules.
204
205 So if a recipient address works intermittently, it can get repeatedly
206 deferred at routing time. The retry hints record remains fresh so the
207 address never reaches the final cutoff time.
208
209 This is a fairly common occurrence when a user is bumping up against
210 their storage quota. Exim had some logic in its local delivery code
211 to deal with this. However it did not apply to per-recipient defers
212 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
213
1ddeb334
TF
214 This change adds a proper retry rule check during routing so that the
215 final cutoff time is checked against the message's age. We only do
216 this check if there is an address retry record and there is not a
217 domain retry record; this implies that previous attempts to handle
218 the address had the retry_use_local_parts option turned on. We use
219 this as an approximation for the destination being like a local
220 delivery, as in LMTP.
67bd1ab3
TF
221
222 I suspect this new check makes the old local delivery cutoff check
223 redundant, but I have not verified this so I left the code in place.

225TF/02 Correct gecos expansion when From: is a prefix of the username.
226
227 Test 0254 submits a message to Exim with the header
228
229 Resent-From: f
230
231 When I ran the test suite under the user fanf2, Exim expanded
232 the header to contain my full name, whereas it should have added
233 a Resent-Sender: header. It erroneously treats any prefix of the
234 username as equal to the username.
235
236 This change corrects that bug.

257JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
258 Server implementation by Todd Lyons, client by JH.
259 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
260 config variable "prdr_enable" controls whether the server
261 advertises the facility. If the client requests PRDR a new
262 acl_data_smtp_prdr ACL is called once for each recipient, after
263 the body content is received and before the acl_smtp_data ACL.
264 The client is controlled by bolth of: a hosts_try_prdr option
265 on the smtp transport, and the server advertisement.
266 Default client logging of deliveries and rejections involving
267 PRDR are flagged with the string "PRDR".

277 This is now consistent with GnuTLS, and is now documented: the
278 previous undocumented portable approach to treating the option as

280 an empty string is now equivalent.

545TF/03 Make the exiwhat support code safe for signals. Previously Exim might
546 lock up or crash if it happened to be inside a call to libc when it
547 got a SIGUSR1 from exiwhat.
548
549 The SIGUSR1 handler appends the current process status to the process
550 log which is later printed by exiwhat. It used to use the general
551 purpose logging code to do this, but several functions it calls are
552 not safe for signals.
553
554 The new output code in the SIGUSR1 handler is specific to the process
555 log, and simple enough that it's easy to inspect for signal safety.
556 Removing some special cases also simplifies the general logging code.
557 Removing the spurious timestamps from the process log simplifies
558 exiwhat.
559
c99ce5c9
TF
560TF/04 Improved ratelimit ACL condition.
561
562 The /noupdate option has been deprecated in favour of /readonly which
563 has clearer semantics. The /leaky, /strict, and /readonly update modes
564 are mutually exclusive. The update mode is no longer included in the
565 database key; it just determines when the database is updated. (This
566 means that when you upgrde Exim will forget old rate measurements.)
567
568 Exim now checks that the per_* options are used with an update mode that
569 makes sense for the current ACL. For example, when Exim is processing a
570 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
571 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
572 must specify per_mail/readonly. If you omit the update mode it defaults to
573 /leaky where that makes sense (as before) or /readonly where required.
574
575 The /noupdate option is now undocumented but still supported for
576 backwards compatibility. It is equivalent to /readonly except that in
577 ACLs where /readonly is required you may specify /leaky/noupdate or
578 /strict/noupdate which are treated the same as /readonly.
579
580 A useful new feature is the /count= option. This is a generalization
581 of the per_byte option, so that you can measure the throughput of other
582 aggregate values. For example, the per_byte option is now equivalent
583 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
584
585 The per_rcpt option has been generalized using the /count= mechanism
586 (though it's more complicated than the per_byte equivalence). When it is
587 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
588 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
589 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
590 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
591 Note that using per_rcpt with a non-readonly update mode in more than
592 one ACL will cause the recipients to be double-counted. (The per_mail
593 and per_byte options don't have this problem.)
594
595 The handling of very low rates has changed slightly. If the computed rate
596 is less than the event's count (usually one) then this event is the first
597 after a long gap. In this case the rate is set to the same as this event's
598 count, so that the first message of a spam run is counted properly.
599
600 The major new feature is a mechanism for counting the rate of unique
601 events. The new per_addr option counts the number of different
602 recipients that someone has sent messages to in the last time period. It
603 behaves like per_rcpt if all the recipient addresses are different, but
604 duplicate recipient addresses do not increase the measured rate. Like
605 the /count= option this is a general mechanism, so the per_addr option
606 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
607 example, measure the rate that a client uses different sender addresses
608 with the options per_mail/unique=$sender_address. There are further
609 details in the main documentation.

1181PH/01 Another patch from the Sieve maintainer.
1182
6a3bceb1
PH
1183PH/02 When an IPv6 address is converted to a string for single-key lookup
1184 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1185 dots are used instead of colons so that keys in lsearch files need not
1186 contain colons. This was done some time before quoting was made available
1187 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1188 (notated using the quote facility) so as to distinguish them from IPv4
1189 keys. This meant that lookups for IP addresses in host lists did not work
1190 for iplsearch lookups.
1191
1192 This has been fixed by arranging for IPv6 addresses to be expressed with
1193 colons if the lookup type is iplsearch. This is not incompatible, because
1194 previously such lookups could never work.

1203MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1204 conversion specification without a maximum field width, thereby enabling
1205 a rogue spamd server to cause a buffer overflow. While nobody in their
1206 right mind would setup Exim to query an untrusted spamd server, an
1207 attacker that gains access to a server running spamd could potentially
1208 exploit this vulnerability to run arbitrary code as the Exim user.

1401PH/29 SMTP synchronization checks are implemented when a command is read -
1402 there is a check that no more input is waiting when there shouldn't be

1404 some time before the response is written. In this time, more input might
1405 arrive, invalidly. So now there are extra checks after an ACL has run for
1406 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1407 pipelining has not been advertised.

1481 the response to the final '.' that terminates a message, but only in the
1482 case where the client has not sent further data following the '.'
1483 (unfortunately, this is allowed). However, in many cases there won't be
1484 any further data because there won't be any more messages to send. A call
1485 to select() can be used: if it shows that the input is "ready", there is
1486 either input waiting, or the socket has been closed. An attempt to read
1487 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1488 would have sent an OK response which the client would never have see.

1499PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1500 fixed by 4.65/MH/01 (is this a record?) are fixed:
1501
1502 (i) An empty string was always treated as zero by the numeric comparison
1503 operators. This behaviour has been restored.
1504
1505 (ii) It is documented that the numeric comparison operators always treat
1506 their arguments as decimal numbers. This was broken in that numbers
1507 starting with 0 were being interpreted as octal.
1508
1509 While fixing these problems I realized that there was another issue that
1510 hadn't been noticed. Values of message_size_limit (both the global option
1511 and the transport option) were treated as octal if they started with 0.
1512 The documentation was vague. These values are now always treated as
1513 decimal, and I will make that clear in the documentation.

PH
1557PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1558 callout verification, Exim cached a "reject" for the entire domain. This
1559 is correct for most verifications, but it is not correct for a recipient
1560 verification with use_sender or use_postmaster set, because in that case
1561 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1562 case of MAIL FROM:<> rejection from other early rejections (e.g.
1563 rejection of HELO). When verifying a recipient using a non-null MAIL
1564 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1565 Whatever the result of the callout, the value of the domain cache is
1566 left unchanged (for any other kind of callout, getting as far as trying
1567 RCPT means that the domain itself is ok).

1601PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1602 hostname. This is wrong, because it relates to the incoming message (and
1603 probably the interface on which it is arriving) and not to the outgoing
1604 callout (which could be using a different interface). This has been
1605 changed to use the value of the helo_data option from the smtp transport
1606 instead - this is what is used when a message is actually being sent. If
1607 there is no remote transport (possible with a router that sets up host
1608 addresses), $smtp_active_hostname is used.

14aa5a05 1610PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1611 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1612 (a) The code assumed that strncpy() returns a negative number on buffer
1613 overflow, which isn't the case. Replaced with Exim's string_format()
1614 function.
1615 (b) There were several signed/unsigned issues. I just did the minimum
1616 hacking in of casts. There is scope for a larger refactoring.
1617 (c) The code used strcasecmp() which is not a standard C function.
1618 Replaced with Exim's strcmpic() function.
1619 (d) The code set only $1; it now sets $auth1 as well.
1620 (e) A simple test gave the error "authentication client didn't specify
1621 service in request". It would seem that Dovecot has changed its
1622 interface. Fortunately there's a specification; I followed it and
1623 changed what the client sends and it appears to be working now.

1628PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1629 address A is aliased to B and C, where B exists and C does not. Without
1630 -v the output is "A verified" because verification stops after a
1631 successful redirection if more than one address is generated. However,
1632 with -v the child addresses are also verified. Exim was outputting "A
1633 failed to verify" and then showing the successful verification for C,
1634 with its parentage. It now outputs "B failed to verify", showing B's
1635 parentage before showing the successful verification of C.

1640
322050c2
PH
1641PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1642 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1643 they consult the DNS. I had assumed they would set it the way they
1644 wanted; and indeed my experiments on Linux seem to show that in some
1645 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1646 To be on the safe side, however, I have now made the interface to
1647 host_find_byname() similar to host_find_bydns(), with an argument
1648 containing the DNS resolver options. The host_find_byname() function now
1649 sets these options at its start, just as host_find_bydns() does. The smtp
1650 transport options dns_qualify_single and dns_search_parents are passed to
1651 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1652 of host_find_byname() use the default settings of RES_DEFNAMES
1653 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1655PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1656 spool_read_header() do less string testing, by means of a preliminary
1657 switch on the second character of optional "-foo" lines. (This is
1658 overdue, caused by the large number of possibilities that now exist.
1659 Originally there were few.) While I was there, I also converted the
1660 str(n)cmp tests so they don't re-test the leading "-" and the first
1661 character, in the hope this might squeeze out yet more improvement.
1662

PH
1663PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1664 flag allowing group syntax was set by the header_syntax check but not
1665 turned off, possible causing trouble later; (2) The flag was not being
1666 set at all for the header_verify test, causing "group"-style headers to
1667 be rejected. I have now set it in this case, and also caused header_
1668 verify to ignore an empty address taken from a group. While doing this, I
1669 came across some other cases where the code for allowing group syntax
1670 while scanning a header line wasn't quite right (mostly, not resetting
1671 the flag correctly in the right place). These bugs could have caused
1672 trouble for malformed header lines. I hope it is now all correct.
1673
602e59e5
PH
1674PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1675 with the "reply" argument non-NULL. The code, however (which originally
1676 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1677 but it didn't always do it. This confused somebody who was copying the
1678 code for some other use. I have removed all the tests.

PH
1680PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1681 feature that was used to support insecure browsers during the U.S. crypto
1682 embargo. It requires special client support, and Exim is probably the
1683 only MTA that supported it -- and would never use it because real RSA is
1684 always available. This code has been removed, because it had the bad
1685 effect of slowing Exim down by computing (never used) parameters for the
1686 RSA_EXPORT functionality.
1687
7befa435
PH
1688PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1689 authenticator to fail if there's a tab character in the incoming data
1690 (there should never be unless someone is messing about, as it's supposed
1691 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1692 if the connection is using TLS or if the remote IP is the same as the
1693 local IP, and the "valid-client-cert option" if a client certificate has
1694 been verified.

1725
1726PH/30 Exim was sometimes attempting to deliver messages that had suffered
1727 address errors (4xx response to RCPT) over the same connection as other
1728 messages routed to the same hosts. Such deliveries are always "forced",
1729 so retry times are not inspected. This resulted in far too many retries
1730 for the affected addresses. The effect occurred only when there were more
1731 hosts than the hosts_max_try setting in the smtp transport when it had
1732 the 4xx errors. Those hosts that it had tried were not added to the list
1733 of hosts for which the message was waiting, so if all were tried, there
1734 was no problem. Two fixes have been applied:
1735
1736 (i) If there are any address or message errors in an SMTP delivery, none
1737 of the hosts (tried or untried) are now added to the list of hosts
1738 for which the message is waiting, so the message should not be a
1739 candidate for sending over the same connection that was used for a
1740 successful delivery of some other message. This seems entirely
1741 reasonable: after all the message is NOT "waiting for some host".
1742 This is so "obvious" that I'm not sure why it wasn't done
1743 previously. Hope I haven't missed anything, but it can't do any
1744 harm, as the worst effect is to miss an optimization.
1745
1746 (ii) If, despite (i), such a delivery is accidentally attempted, the
1747 routing retry time is respected, so at least it doesn't keep
1748 hammering the server.

1763PH/35 The error "getsockname() failed: connection reset by peer" was being
1764 written to the panic log as well as the main log, but it isn't really
1765 panic-worthy as it just means the connection died rather early on. I have
1766 removed the panic log writing for the ECONNRESET error when getsockname()
1767 fails.
1768
48c7f9e2
PH
1769PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1770 runs only) independently of the message's sender address. This meant
1771 that, if the 4xx error was in fact related to the sender, a different
1772 message to the same recipient with a different sender could confuse
1773 things. In particualar, this can happen when sending to a greylisting
1774 server, but other circumstances could also provoke similar problems.
1775 I have changed the default so that the retry time for these errors is now
1776 based a combination of the sender and recipient addresses. This change
1777 can be overridden by setting address_retry_include_sender=false in the
1778 smtp transport.

2048 Unfortunately, if there is a major crisis, such as a disk failure,
2049 tcp-wrappers gives "deny", whereas what one would like would be some
2050 kind of temporary error. A kludge has been added to help with this.
2051 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2052 554 error is used if errno is still zero or contains ENOENT (which occurs
2053 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2054 451 error is used.

2090PH/01 The code for finding all the local interface addresses on a FreeBSD
2091 system running IPv6 was broken. This may well have applied to all BSD
2092 systems, as well as to others that have similar system calls. The broken
2093 code found IPv4 interfaces correctly, but gave incorrect values for the
2094 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2095 that it would not match correctly against @[] and not recognize the IPv6
2096 addresses as local.

2139 autoreply, Exim could try to deliver to a non-existent relative file

2175 Instead, it always explicitly searches for A/AAAA records. This avoids
2176 major problems that occur when a DNS server includes only records of one
2177 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2178 fixed another bug: if SRV records were looked up and the corresponding
2179 address records were *not* found in the additional section, the port
2180 values from the SRV records were lost.

2190PH/19 When calculating a retry time, Exim used to measure the "time since
2191 failure" by looking at the "first failed" field in the retry record. Now
2192 it does not use this if it is later than than the arrival time of the
2193 message. Instead it uses the arrival time. This makes for better
2194 behaviour in cases where some deliveries succeed, thus re-setting the
2195 "first failed" field. An example is a quota failure for a huge message
2196 when small messages continue to be delivered. Without this change, the
2197 "time since failure" will always be short, possible causing more frequent
2198 delivery attempts for the huge message than are intended.

2295PH/42 The content-scanning code uses fopen() to create files in which to put

2298 files with open(), and sets the required mode explicitly. Thus, these
2299 files were ending up world-writeable. This was not a big issue, because,
2300 being within the spool directory, they were not world-accessible. I have
2301 created a function called modefopen, which takes an additional mode
2302 argument. It sets umask(777), creates the file, chmods it to the required
2303 mode, then resets the umask. All the relevant calls to fopen() in the

2344 was used in LMTP mode. This meant that they could be retried too
2345 frequently, and not timed out correctly.
2346
2347 (ii) Exim was setting the flag that allows error details to be returned
2348 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2349 recipients that were returned after the DATA command.

2351PH/53 This is related to PH/52, but is more general: for any failing address,

2425PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2426 function verify_get_ident() calls ip_connect() to connect a socket, but
2427 if the "connect()" function timed out, ip_connect() used to close the
2428 socket. However, verify_get_ident() also closes the socket later, and in
2429 between Exim writes to the log, which may get opened at this point. When
2430 the socket was closed in ip_connect(), the log could get the same file
2431 descriptor number as the socket. This naturally causes chaos. The fix is
2432 not to close the socket in ip_connect(); the socket should be closed by
2433 the function that creates it. There was only one place in the code where
2434 this was missing, in the iplookup router, which I don't think anybody now
2435 uses, but I've fixed it anyway.

2458
2459 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2460 string.
2461
2462 (3) Reset the variables that are obtained from the first argument of
2463 ${prvscheck and used in the second argument before leaving the code,
2464 because their memory is reclaimed, so using them afterwards may do
2465 silly things.
2466
2467 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2468 one (it's much easier than Tom thought :-).

2491PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2492 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2493 not being looked up in the rDNS to get a host name, Exim was showing the
2494 IP address twice in Received: lines, even though the IP addresses were
2495 identical. For example:
2496
2497 Received: from [1.2.3.4] (helo=[1.2.3.4])
2498
2499 However, if the real host name was known, it was omitting the HELO data
2500 if it matched the actual IP address. This has been tidied up so that it
2501 doesn't show the same IP address twice.

2530 Auto-submitted: auto-generated
2531
2532 in the messages that it generates (bounce messages and others, such as
2533 warnings). In the case of bounce messages for non-SMTP mesages, there was
2534 also a typo: it was using "Auto_submitted" (underscore instead of
2535 hyphen). Since every message generated by Exim is necessarily in response
2536 to another message, thes have all been changed to:
2537
2538 Auto-Submitted: auto-replied
2539
2540 in accordance with these statements in the RFC:
2541
2542 The auto-replied keyword:
2543
2544 - SHOULD be used on messages sent in direct response to another

2590PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated

2592 the IP address, check_host() was doing a simple string comparison with
2593 addresses acquired from the DNS when checking that the found name did
2594 have the original IP as one of its addresses. Since any found IPv6
2595 addresses are likely to be in abbreviated form, the comparison could
2596 fail. Luckily, there already exists a function for doing the comparison
2597 by converting both addresses to binary, so now that is used instead of
2598 the text comparison.

PH
2765PH/33 Added "verify = not_blind".
2766
2767PH/34 There are settings for CHOWN_COMMAND and MV_COMMAND that can be used in
2768 Local/Makefile (with some defaults set). These are used in built scripts
2769 such as exicyclog, but they have never been used in the exim_install
2770 script (though there are many overriding facilities there). I have
2771 arranged that the exim_install script now takes note of these two
2772 settings.
2773
2774PH/35 Installed configuration files for Dragonfly.

PH
2776PH/36 When a locally submitted message by a trusted user did not contain a
2777 From: header, and the sender address was obtained from -f or from an SMTP
2778 MAIL command, and the trusted user did not use -F to supply a sender
2779 name, $originator_name was incorrectly used when constructing a From:
2780 header. Furthermore, $originator_name was used for submission mode
2781 messages from external hosts without From: headers in a similar way,
2782 which is clearly wrong.

PH
2784PH/37 Added control=suppress_local_fixups.

PH
2786PH/38 When log_selector = +received_sender was set, and the addition of the
2787 sender made the log line's construction buffer exactly full, or one byte
2788 less than full, an overflow happened when the terminating "\n" was
2789 subsequently added.
2790
1130bfb0
PH

2862PH/01 When a transport filter timed out in a pipe delivery, and the pipe

2872PH/03 The warning log line about a condition test deferring for a "warn" verb

PH
2895PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2896 with the definition in sysexits.h (which is #included earlier).
2897 Fortunately, Exim does not actually use EX_OK. The code used to try to
2898 preserve the sysexits.h value, by assumimg that macro definitions were
2899 scanned for macro replacements. I have been disabused of this notion,
2900 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 2901
958541e9
PH
2902PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2903 in the smtp transport. When a block could not be written in a single
2904 write() function, the timeout was being re-applied to each part-write.
2905 This seems wrong - if the receiver was accepting one byte at a time it
2906 would take for ever. The timeout is now adjusted when this happens. It
2907 doesn't have to be particularly precise.

2941PH/08 The ${def test on a variable was returning false if the variable's

2944
2945PH/09 The syntax error of a character other than { following "${if
2946 def:variable_name" (after optional whitespace) was not being diagnosed.
2947 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
2948 accidental colon was present, for example, could give incorrect results.

PH
2973PH/15 The code I had for printing potentially long long variables in PH/11
2974 above was not the best (it lost precision). The length of off_t variables
2975 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
2976 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
2977 to be "long long int" or "long int". This is needed for the internal
2978 formatting function string_vformat().

PH
2980PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2981 the configuration file to be ":syslog", then the script "guesses" where
2982 the logs files are, rather than using the compiled in default. In our
2983 case the guess is not the same as the compiled default, so the script
2984 suddenly stopped working when I started to use syslog. The patch checks
2985 to see if log_file_path is "". If so, it attempts to read it from exim
2986 with no configuration file to get the compiled in version, before it
2987 falls back to the previous guessing code."

PH
2996PH/18 If the "use_postmaster" option was set for a recipient callout together

2999 test. It is now used for both.

PH
3001PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3002 patch removes a few documentation additions to RFC 3028, because the
3003 latest draft now contains them. It adds the new en;ascii-case comparator
3004 and a new error check for 8bit text in MIME parts. Comparator and

3006 extension, but it is not well tested yet (read: it works for me)."

PH
3008PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3009 rework some of the code of TK/09 above to avoid the hardwired use of

PH
3030PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3031 databases so that it will be absolutely obvious if a crash occurs in the
3032 DB library. This is a regular occurrence (often caused by mis-matched
3033 db.h files).

ff790e47 3035PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3036 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3037 picked up on a user's system that detects such things. There doesn't seem
3038 to be a gcc warning option for this - only an attribute that has to be
3039 put on the function's prototype. It seems that in Fedora Core 4 they have
3040 set this on a number of new functions. No doubt there will be more in due
3041 course.
ff790e47 3042
5417f6d1
PH
3043PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3044 specify a transport. However, if an address that was verified by such a
3045 router was the subject of a callout, Exim crashed because it tried to
3046 read the rcpt_include_affixes from the non-existent transport. Now it
3047 just assumes that the setting of that option is false. This bug was
3048 introduced by 4.51/PH/31.
3049
59cf8544
PH
3050PH/28 Changed -d+all to exclude +memory, because that information is very

PH
3058PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3059 aren't the modern standard, and it seems that some systems' include files
3060 don't always have them. Exim was already checking for some of the newer
3061 ones like T_AAAA, and defining it itself. I've added checks for all the
3062 record types that Exim uses.
3063
182ad5cf
PH
3064PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3065 not automatically generating a new one, as it is supposed to. This
3066 prevented TLS from working. If the file did exist, but contained invalid
3067 data, a new version was generated, as expected. It was only the case of a
3068 non-existent file that was broken.

3079PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3080 the use of a port name that isn't defined in /etc/services) occurred, the

SC
3086SC/08 Eximstats: whilst parsing the mainlog(s), store information about

3114 to test Sieve filters that use "vacation".
3115
3116PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3117 that changes the way the GnuTLS parameters are stored in the cache file.
3118 The new format can be generated externally. For backward compatibility,
3119 if the data in the cache doesn't make sense, Exim assumes it has read an
3120 old-format file, and it generates new data and writes a new file. This
3121 means that you can't go back to an older release without removing the
3122 file.
3123
3124PH/03 A redirect router that has both "unseen" and "one_time" set does not
3125 work if there are any delivery delays because "one_time" forces the
3126 parent to be marked "delivered", so its unseen clone is never tried
3127 again. For this reason, Exim now forbids the simultaneous setting of
3128 these two options.
3129
3130PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3131 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3132 entry if you want to know the details. The fix, however, neglected to
3133 consider the case when local delivery batching is involved. The test for
3134 "previously delivered" was not happening when checking to see if an
3135 address could be batched with a previous (undelivered) one; under
3136 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3137 address.
1a46a8c5
PH
3138
3139PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3140 in its include files, and this causes problems building Exim.
3141
3142PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3143 header_syntax) but Exim was just ignoring anything given after a slash.
3144 In particular, this caused confusion with an attempt to use "verify =
3145 reverse_host_lookup/defer_ok". An error is now given when options are
3146 supplied for verify items that do not have them. (Maybe reverse_host_
3147 lookup should have a defer_ok option, but that's a different point.)
3148
3149PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3150 defined by RFC 821) to 2048, because there were problems with some AUTH
3151 commands, and RFC 1869 says the size should be increased for extended
3152 SMTP commands that take arguments.
3153
3154PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3155 Finch).

3199PH/19 When an Exim process that is running as root has to create an Exim log
3200 file, it does so in a subprocess that runs as exim:exim so as to get the
3201 ownership right at creation (otherwise, other Exim processes might see
3202 the file with the wrong ownership). There was no test for failure of this
3203 fork() call, which would lead to the process getting stuck as it waited
3204 for a non-existent subprocess. Forks do occasionally fail when resources
3205 run out. I reviewed all the other calls to fork(); they all seem to check
3206 for failure.

3208PH/20 When checking for unexpected SMTP input at connect time (before writing

3210 from the read() function. If the client had disconnected by this time,
3211 the result was a log entry for a synchronization error with an empty
3212 string after "input=" when read() returned zero. If read() returned -1
3213 (an event I could not check), uninitialized data bytes were printed.

PH
3225PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3226 hadn't been configured. The fix is from Juergen Kreileder, who
3227 understands it better than I do:
3228
3229 "Here's what I see happening with three configured cyrus_sasl
3230 authenticators configured (plain, login, cram-md5):
3231
3232 On startup auth_cyrus_sasl_init() gets called for each of these.
3233 This means three calls to sasl_listmech() without a specified mech_list.
3234 => SASL tests which mechs of all available mechs actually work
3235 => three warnings about OTP not working
3236 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3237
3238 With the patch, sasl_listmech() also gets called three times. But now
3239 SASL's mech_list option is set to the server_mech specified in the the
3240 authenticator. Or in other words, the answer from sasl_listmech()
3241 gets limited to just the mech you're testing for (which is different
3242 for each call.)
3243 => the return list contains just 'plain' or 'login', 'cram-md5' or
3244 nothing depending on the value of ob->server_mech.
3245
3246 I've just tested the patch: Authentication still works fine,
3247 unavailable mechs specified in the exim configuration are still
3248 caught, and the auth.log warnings about OTP are gone."

3284 . Second host offers TLS and a TLS session is established;

PH
3312PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3313 the grounds that routing the same address twice would always produce the
3314 same answer. This might have been true once, but it is certainly no
3315 longer true now. Routing a child address may depend on the previous
3316 routing that produced that child. Some complicated redirection strategies
3317 went wrong when messages had multiple recipients, and made Exim's
3318 behaviour dependent on the order in which the addresses were given.
3319
3320 I have moved the duplicate checking until after the routing is complete.
3321 Exim scans the addresses that are assigned to local and remote
3322 transports, and removes any duplicates. This means that more work will be
3323 done, as duplicates will always all be routed, but duplicates are
3324 presumably rare, so I don't expect this is of any significance.
3325
3326 For deliveries to pipes, files, and autoreplies, the duplicate checking
3327 still happens during the routing process, since they are not going to be
3328 routed further.

3334 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3335 blindly assumes that writes won't block so it may never time out."

3369PH/45 In a pipe transport, although a timeout while waiting for the pipe
3370 process to complete was treated as a delivery failure, a timeout while
3371 writing the message to the pipe was logged, but erroneously treated as a
3372 successful delivery. Such timeouts include transport filter timeouts. For
3373 consistency with the overall process timeout, these timeouts are now
3374 treated as errors, giving rise to delivery failures by default. However,
3375 there is now a new Boolean option for the pipe transport called
3376 timeout_defer, which, if set TRUE, converts the failures into defers for
