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

221TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
222
223 When a queue runner is handling a message, Exim first routes the
224 recipient addresses, during which it prunes them based on the retry
225 hints database. After that it attempts to deliver the message to
226 any remaining recipients. It then updates the hints database using
227 the retry rules.
228
229 So if a recipient address works intermittently, it can get repeatedly
230 deferred at routing time. The retry hints record remains fresh so the
231 address never reaches the final cutoff time.
232
233 This is a fairly common occurrence when a user is bumping up against
234 their storage quota. Exim had some logic in its local delivery code
235 to deal with this. However it did not apply to per-recipient defers
236 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
237
1ddeb334
TF
238 This change adds a proper retry rule check during routing so that the
239 final cutoff time is checked against the message's age. We only do
240 this check if there is an address retry record and there is not a
241 domain retry record; this implies that previous attempts to handle
242 the address had the retry_use_local_parts option turned on. We use
243 this as an approximation for the destination being like a local
244 delivery, as in LMTP.
67bd1ab3
TF
245
246 I suspect this new check makes the old local delivery cutoff check
247 redundant, but I have not verified this so I left the code in place.

250
251 Test 0254 submits a message to Exim with the header
252
253 Resent-From: f
254
255 When I ran the test suite under the user fanf2, Exim expanded
256 the header to contain my full name, whereas it should have added
257 a Resent-Sender: header. It erroneously treats any prefix of the
258 username as equal to the username.
259
260 This change corrects that bug.

281JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
282 Server implementation by Todd Lyons, client by JH.
283 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
284 config variable "prdr_enable" controls whether the server
285 advertises the facility. If the client requests PRDR a new
286 acl_data_smtp_prdr ACL is called once for each recipient, after
287 the body content is received and before the acl_smtp_data ACL.
288 The client is controlled by bolth of: a hosts_try_prdr option
289 on the smtp transport, and the server advertisement.
290 Default client logging of deliveries and rejections involving
291 PRDR are flagged with the string "PRDR".

569TF/03 Make the exiwhat support code safe for signals. Previously Exim might
570 lock up or crash if it happened to be inside a call to libc when it
571 got a SIGUSR1 from exiwhat.
572
573 The SIGUSR1 handler appends the current process status to the process
574 log which is later printed by exiwhat. It used to use the general
575 purpose logging code to do this, but several functions it calls are
576 not safe for signals.
577
578 The new output code in the SIGUSR1 handler is specific to the process
579 log, and simple enough that it's easy to inspect for signal safety.
580 Removing some special cases also simplifies the general logging code.
581 Removing the spurious timestamps from the process log simplifies
582 exiwhat.
583
c99ce5c9
TF
584TF/04 Improved ratelimit ACL condition.
585
586 The /noupdate option has been deprecated in favour of /readonly which
587 has clearer semantics. The /leaky, /strict, and /readonly update modes
588 are mutually exclusive. The update mode is no longer included in the
589 database key; it just determines when the database is updated. (This
590 means that when you upgrde Exim will forget old rate measurements.)
591
592 Exim now checks that the per_* options are used with an update mode that
593 makes sense for the current ACL. For example, when Exim is processing a
594 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
595 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
596 must specify per_mail/readonly. If you omit the update mode it defaults to
597 /leaky where that makes sense (as before) or /readonly where required.
598
599 The /noupdate option is now undocumented but still supported for
600 backwards compatibility. It is equivalent to /readonly except that in
601 ACLs where /readonly is required you may specify /leaky/noupdate or
602 /strict/noupdate which are treated the same as /readonly.
603
604 A useful new feature is the /count= option. This is a generalization
605 of the per_byte option, so that you can measure the throughput of other
606 aggregate values. For example, the per_byte option is now equivalent
607 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
608
609 The per_rcpt option has been generalized using the /count= mechanism
610 (though it's more complicated than the per_byte equivalence). When it is
611 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
612 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
613 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
614 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
615 Note that using per_rcpt with a non-readonly update mode in more than
616 one ACL will cause the recipients to be double-counted. (The per_mail
617 and per_byte options don't have this problem.)
618
619 The handling of very low rates has changed slightly. If the computed rate
620 is less than the event's count (usually one) then this event is the first
621 after a long gap. In this case the rate is set to the same as this event's
622 count, so that the first message of a spam run is counted properly.
623
624 The major new feature is a mechanism for counting the rate of unique
625 events. The new per_addr option counts the number of different
626 recipients that someone has sent messages to in the last time period. It
627 behaves like per_rcpt if all the recipient addresses are different, but
628 duplicate recipient addresses do not increase the measured rate. Like
629 the /count= option this is a general mechanism, so the per_addr option
630 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
631 example, measure the rate that a client uses different sender addresses
632 with the options per_mail/unique=$sender_address. There are further
633 details in the main documentation.

843PP/06 Bugzilla 1071: fix delivery logging with untrusted macros.
844 If dropping privileges for untrusted macros, we disabled normal logging
845 on the basis that it would fail; for the Exim run-time user, this is not
846 the case, and it resulted in successful deliveries going unlogged.
847 Fixed. Reported by Andreas Metzler.

1183 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1184 were called 'true' and it seems that C99 defines that as a reserved
1185 keyword to be used with 'bool' variable types. That means you could
1186 not include C99-style headers which use bools without triggering
1187 build errors in sieve.c.

1205PH/01 Another patch from the Sieve maintainer.
1206
6a3bceb1
PH
1207PH/02 When an IPv6 address is converted to a string for single-key lookup
1208 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1209 dots are used instead of colons so that keys in lsearch files need not
1210 contain colons. This was done some time before quoting was made available
1211 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1212 (notated using the quote facility) so as to distinguish them from IPv4
1213 keys. This meant that lookups for IP addresses in host lists did not work
1214 for iplsearch lookups.
1215
1216 This has been fixed by arranging for IPv6 addresses to be expressed with
1217 colons if the lookup type is iplsearch. This is not incompatible, because
1218 previously such lookups could never work.
1219
1220 The situation is now rather anomolous, since one *can* have colons in
1221 ordinary lsearch keys. However, making the change in all cases is
1222 incompatible and would probably break a number of configurations.

1227MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1228 conversion specification without a maximum field width, thereby enabling
1229 a rogue spamd server to cause a buffer overflow. While nobody in their
1230 right mind would setup Exim to query an untrusted spamd server, an
1231 attacker that gains access to a server running spamd could potentially
1232 exploit this vulnerability to run arbitrary code as the Exim user.

1237MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1238 a directory entry by the name of the lookup key. Previously, if a
1239 symlink pointed to a non-existing file or a file in a directory that
1240 Exim lacked permissions to read, a lookup for a key matching that

1425PH/29 SMTP synchronization checks are implemented when a command is read -
1426 there is a check that no more input is waiting when there shouldn't be
1427 any. However, for some commands, a delay in an ACL can mean that it is
1428 some time before the response is written. In this time, more input might
1429 arrive, invalidly. So now there are extra checks after an ACL has run for
1430 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1431 pipelining has not been advertised.

1446 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1447 was a macro that became an assignment, so it seemed to work. This has
1448 changed to a proper function call with a void return, hence the compile
1449 error. Exim's code has been fixed.

PH
1505 the response to the final '.' that terminates a message, but only in the
1506 case where the client has not sent further data following the '.'
1507 (unfortunately, this is allowed). However, in many cases there won't be
1508 any further data because there won't be any more messages to send. A call
1509 to select() can be used: if it shows that the input is "ready", there is
1510 either input waiting, or the socket has been closed. An attempt to read
1511 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1512 would have sent an OK response which the client would never have see.

1523PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1524 fixed by 4.65/MH/01 (is this a record?) are fixed:
1525
1526 (i) An empty string was always treated as zero by the numeric comparison
1527 operators. This behaviour has been restored.
1528
1529 (ii) It is documented that the numeric comparison operators always treat
1530 their arguments as decimal numbers. This was broken in that numbers
1531 starting with 0 were being interpreted as octal.
1532
1533 While fixing these problems I realized that there was another issue that
1534 hadn't been noticed. Values of message_size_limit (both the global option
1535 and the transport option) were treated as octal if they started with 0.
1536 The documentation was vague. These values are now always treated as
1537 decimal, and I will make that clear in the documentation.

1582 callout verification, Exim cached a "reject" for the entire domain. This
1583 is correct for most verifications, but it is not correct for a recipient
1584 verification with use_sender or use_postmaster set, because in that case
1585 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1586 case of MAIL FROM:<> rejection from other early rejections (e.g.
1587 rejection of HELO). When verifying a recipient using a non-null MAIL
1588 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1589 Whatever the result of the callout, the value of the domain cache is
1590 left unchanged (for any other kind of callout, getting as far as trying
1591 RCPT means that the domain itself is ok).

1625PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1626 hostname. This is wrong, because it relates to the incoming message (and
1627 probably the interface on which it is arriving) and not to the outgoing
1628 callout (which could be using a different interface). This has been
1629 changed to use the value of the helo_data option from the smtp transport
1630 instead - this is what is used when a message is actually being sent. If
1631 there is no remote transport (possible with a router that sets up host
1632 addresses), $smtp_active_hostname is used.

7befa435 1635 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1636 (a) The code assumed that strncpy() returns a negative number on buffer
1637 overflow, which isn't the case. Replaced with Exim's string_format()
1638 function.
1639 (b) There were several signed/unsigned issues. I just did the minimum
1640 hacking in of casts. There is scope for a larger refactoring.
1641 (c) The code used strcasecmp() which is not a standard C function.
1642 Replaced with Exim's strcmpic() function.
1643 (d) The code set only $1; it now sets $auth1 as well.
1644 (e) A simple test gave the error "authentication client didn't specify
1645 service in request". It would seem that Dovecot has changed its
1646 interface. Fortunately there's a specification; I followed it and
1647 changed what the client sends and it appears to be working now.

1652PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1653 address A is aliased to B and C, where B exists and C does not. Without
1654 -v the output is "A verified" because verification stops after a
1655 successful redirection if more than one address is generated. However,
1656 with -v the child addresses are also verified. Exim was outputting "A
1657 failed to verify" and then showing the successful verification for C,
1658 with its parentage. It now outputs "B failed to verify", showing B's
1659 parentage before showing the successful verification of C.

1664
322050c2
PH
1665PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1666 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1667 they consult the DNS. I had assumed they would set it the way they
1668 wanted; and indeed my experiments on Linux seem to show that in some
1669 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1670 To be on the safe side, however, I have now made the interface to
1671 host_find_byname() similar to host_find_bydns(), with an argument
1672 containing the DNS resolver options. The host_find_byname() function now
1673 sets these options at its start, just as host_find_bydns() does. The smtp
1674 transport options dns_qualify_single and dns_search_parents are passed to
1675 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1676 of host_find_byname() use the default settings of RES_DEFNAMES
1677 (qualify_single) but not RES_DNSRCH (search_parents).

1679PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1680 spool_read_header() do less string testing, by means of a preliminary
1681 switch on the second character of optional "-foo" lines. (This is
1682 overdue, caused by the large number of possibilities that now exist.
1683 Originally there were few.) While I was there, I also converted the
1684 str(n)cmp tests so they don't re-test the leading "-" and the first
1685 character, in the hope this might squeeze out yet more improvement.

PH
1687PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1688 flag allowing group syntax was set by the header_syntax check but not
1689 turned off, possible causing trouble later; (2) The flag was not being
1690 set at all for the header_verify test, causing "group"-style headers to
1691 be rejected. I have now set it in this case, and also caused header_
1692 verify to ignore an empty address taken from a group. While doing this, I
1693 came across some other cases where the code for allowing group syntax
1694 while scanning a header line wasn't quite right (mostly, not resetting
1695 the flag correctly in the right place). These bugs could have caused
1696 trouble for malformed header lines. I hope it is now all correct.

PH
1698PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1699 with the "reply" argument non-NULL. The code, however (which originally
1700 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1701 but it didn't always do it. This confused somebody who was copying the
1702 code for some other use. I have removed all the tests.

PH
1704PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1705 feature that was used to support insecure browsers during the U.S. crypto
1706 embargo. It requires special client support, and Exim is probably the
1707 only MTA that supported it -- and would never use it because real RSA is
1708 always available. This code has been removed, because it had the bad
1709 effect of slowing Exim down by computing (never used) parameters for the
1710 RSA_EXPORT functionality.

PH
1712PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1713 authenticator to fail if there's a tab character in the incoming data
1714 (there should never be unless someone is messing about, as it's supposed
1715 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1716 if the connection is using TLS or if the remote IP is the same as the
1717 local IP, and the "valid-client-cert option" if a client certificate has
1718 been verified.

1749
1750PH/30 Exim was sometimes attempting to deliver messages that had suffered
1751 address errors (4xx response to RCPT) over the same connection as other
1752 messages routed to the same hosts. Such deliveries are always "forced",
1753 so retry times are not inspected. This resulted in far too many retries
1754 for the affected addresses. The effect occurred only when there were more
1755 hosts than the hosts_max_try setting in the smtp transport when it had
1756 the 4xx errors. Those hosts that it had tried were not added to the list
1757 of hosts for which the message was waiting, so if all were tried, there
1758 was no problem. Two fixes have been applied:
1759
1760 (i) If there are any address or message errors in an SMTP delivery, none
1761 of the hosts (tried or untried) are now added to the list of hosts
1762 for which the message is waiting, so the message should not be a
1763 candidate for sending over the same connection that was used for a
1764 successful delivery of some other message. This seems entirely
1765 reasonable: after all the message is NOT "waiting for some host".
1766 This is so "obvious" that I'm not sure why it wasn't done
1767 previously. Hope I haven't missed anything, but it can't do any
1768 harm, as the worst effect is to miss an optimization.
1769
1770 (ii) If, despite (i), such a delivery is accidentally attempted, the
1771 routing retry time is respected, so at least it doesn't keep
1772 hammering the server.

1787PH/35 The error "getsockname() failed: connection reset by peer" was being
1788 written to the panic log as well as the main log, but it isn't really
1789 panic-worthy as it just means the connection died rather early on. I have
1790 removed the panic log writing for the ECONNRESET error when getsockname()
1791 fails.
1792
48c7f9e2
PH
1793PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1794 runs only) independently of the message's sender address. This meant
1795 that, if the 4xx error was in fact related to the sender, a different
1796 message to the same recipient with a different sender could confuse
1797 things. In particualar, this can happen when sending to a greylisting
1798 server, but other circumstances could also provoke similar problems.
1799 I have changed the default so that the retry time for these errors is now
1800 based a combination of the sender and recipient addresses. This change
1801 can be overridden by setting address_retry_include_sender=false in the
1802 smtp transport.

2070PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2072 Unfortunately, if there is a major crisis, such as a disk failure,
2073 tcp-wrappers gives "deny", whereas what one would like would be some
2074 kind of temporary error. A kludge has been added to help with this.
2075 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2076 554 error is used if errno is still zero or contains ENOENT (which occurs
2077 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2078 451 error is used.

2114PH/01 The code for finding all the local interface addresses on a FreeBSD
2115 system running IPv6 was broken. This may well have applied to all BSD
2116 systems, as well as to others that have similar system calls. The broken
2117 code found IPv4 interfaces correctly, but gave incorrect values for the
2118 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2119 that it would not match correctly against @[] and not recognize the IPv6
2120 addresses as local.

2163 autoreply, Exim could try to deliver to a non-existent relative file

2186 (a) Failures to set uid/gid, the current directory, or a process leader
2187 in a subprocess such as that created by queryprogram now generate
2188 suitable debugging ouput when -d is set.

2197PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2198 additional section of a DNS packet that returns MX or SRV records.
2199 Instead, it always explicitly searches for A/AAAA records. This avoids
2200 major problems that occur when a DNS server includes only records of one
2201 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2202 fixed another bug: if SRV records were looked up and the corresponding
2203 address records were *not* found in the additional section, the port
2204 values from the SRV records were lost.

2206PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2214PH/19 When calculating a retry time, Exim used to measure the "time since
2215 failure" by looking at the "first failed" field in the retry record. Now
2216 it does not use this if it is later than than the arrival time of the
2217 message. Instead it uses the arrival time. This makes for better
2218 behaviour in cases where some deliveries succeed, thus re-setting the
2219 "first failed" field. An example is a quota failure for a huge message
2220 when small messages continue to be delivered. Without this change, the
2221 "time since failure" will always be short, possible causing more frequent
2222 delivery attempts for the huge message than are intended.

2319PH/42 The content-scanning code uses fopen() to create files in which to put

2322 files with open(), and sets the required mode explicitly. Thus, these
2323 files were ending up world-writeable. This was not a big issue, because,
2324 being within the spool directory, they were not world-accessible. I have
2325 created a function called modefopen, which takes an additional mode
2326 argument. It sets umask(777), creates the file, chmods it to the required
2327 mode, then resets the umask. All the relevant calls to fopen() in the

2354PH/50 When an Exim quota was set without a file count quota, and mailbox_size

2357 of files (along with the size), even though it did not need this
2358 information. It now does the scan only if it needs to find either the
2359 size of the count of files.

2363PH/52 Two bugs concerned with error handling when the smtp transport is
2364 used in LMTP mode:
2365
2366 (i) Exim was not creating retry information for temporary errors given
2367 for individual recipients after the DATA command when the smtp transport
2368 was used in LMTP mode. This meant that they could be retried too
2369 frequently, and not timed out correctly.
2370
2371 (ii) Exim was setting the flag that allows error details to be returned
2372 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2373 recipients that were returned after the DATA command.
2374
2375PH/53 This is related to PH/52, but is more general: for any failing address,
2376 when detailed error information was permitted to be returned to the
2377 sender, but the error was temporary, then after the final timeout, only
2378 "retry timeout exceeded" was returned. Now it returns the full error as
2379 well as "retry timeout exceeded".

2438 been fixed. However, if bounce_return_message is true and bounce_return_
2439 body is false, the headers that are returned for a non-SMTP message

2449PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2450 function verify_get_ident() calls ip_connect() to connect a socket, but
2451 if the "connect()" function timed out, ip_connect() used to close the
2452 socket. However, verify_get_ident() also closes the socket later, and in
2453 between Exim writes to the log, which may get opened at this point. When
2454 the socket was closed in ip_connect(), the log could get the same file
2455 descriptor number as the socket. This naturally causes chaos. The fix is
2456 not to close the socket in ip_connect(); the socket should be closed by
2457 the function that creates it. There was only one place in the code where
2458 this was missing, in the iplookup router, which I don't think anybody now
2459 uses, but I've fixed it anyway.

2482
2483 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2484 string.
2485
2486 (3) Reset the variables that are obtained from the first argument of
2487 ${prvscheck and used in the second argument before leaving the code,
2488 because their memory is reclaimed, so using them afterwards may do
2489 silly things.
2490
2491 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2492 one (it's much easier than Tom thought :-).
2493
2494 (5) Because of (4), we can now allow for the use of $prvscheck_result

2510 may be more than one such address. If so, they are comma-separated, like

2515PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2516 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2517 not being looked up in the rDNS to get a host name, Exim was showing the
2518 IP address twice in Received: lines, even though the IP addresses were
2519 identical. For example:
2520
2521 Received: from [1.2.3.4] (helo=[1.2.3.4])
2522
2523 However, if the real host name was known, it was omitting the HELO data
2524 if it matched the actual IP address. This has been tidied up so that it
2525 doesn't show the same IP address twice.

2551PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to

2553
2554 Auto-submitted: auto-generated
2555
2556 in the messages that it generates (bounce messages and others, such as
2557 warnings). In the case of bounce messages for non-SMTP mesages, there was
2558 also a typo: it was using "Auto_submitted" (underscore instead of
2559 hyphen). Since every message generated by Exim is necessarily in response
2560 to another message, thes have all been changed to:
2561
2562 Auto-Submitted: auto-replied
2563
2564 in accordance with these statements in the RFC:
2565
2566 The auto-replied keyword:
2567
2568 - SHOULD be used on messages sent in direct response to another
2569 message by an automatic process,
2570
2571 - MUST NOT be used on manually-generated messages,

2573 - MAY be used on Delivery Status Notifications (DSNs) and Message
2574 Disposition Notifications (MDNs),

2614PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2615 canonical form (as documented). However, after a host name lookup from
2616 the IP address, check_host() was doing a simple string comparison with
2617 addresses acquired from the DNS when checking that the found name did
2618 have the original IP as one of its addresses. Since any found IPv6
2619 addresses are likely to be in abbreviated form, the comparison could
2620 fail. Luckily, there already exists a function for doing the comparison
2621 by converting both addresses to binary, so now that is used instead of
2622 the text comparison.

2920 with the definition in sysexits.h (which is #included earlier).
2921 Fortunately, Exim does not actually use EX_OK. The code used to try to
2922 preserve the sysexits.h value, by assumimg that macro definitions were
2923 scanned for macro replacements. I have been disabused of this notion,
2924 so now the code just undefines EX_OK before #including unistd.h.

2929 This seems wrong - if the receiver was accepting one byte at a time it
2930 would take for ever. The timeout is now adjusted when this happens. It
2931 doesn't have to be particularly precise.

3007 case the guess is not the same as the compiled default, so the script
3008 suddenly stopped working when I started to use syslog. The patch checks
3009 to see if log_file_path is "". If so, it attempts to read it from exim

3011 falls back to the previous guessing code."

3140PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3141 that changes the way the GnuTLS parameters are stored in the cache file.
3142 The new format can be generated externally. For backward compatibility,
3143 if the data in the cache doesn't make sense, Exim assumes it has read an
3144 old-format file, and it generates new data and writes a new file. This
3145 means that you can't go back to an older release without removing the
3146 file.
3147
3148PH/03 A redirect router that has both "unseen" and "one_time" set does not
3149 work if there are any delivery delays because "one_time" forces the

3152 these two options.

3156 entry if you want to know the details. The fix, however, neglected to
3157 consider the case when local delivery batching is involved. The test for
3158 "previously delivered" was not happening when checking to see if an
3159 address could be batched with a previous (undelivered) one; under
3160 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3161 address.

3163PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
3164 in its include files, and this causes problems building Exim.
3165
3166PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3167 header_syntax) but Exim was just ignoring anything given after a slash.
3168 In particular, this caused confusion with an attempt to use "verify =
3169 reverse_host_lookup/defer_ok". An error is now given when options are
3170 supplied for verify items that do not have them. (Maybe reverse_host_
3171 lookup should have a defer_ok option, but that's a different point.)
3172
3173PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3174 defined by RFC 821) to 2048, because there were problems with some AUTH
3175 commands, and RFC 1869 says the size should be increased for extended
3176 SMTP commands that take arguments.
3177
3178PH/08 Added ${dlfunc dynamically loaded function for expansion (code from Tony
3179 Finch).

3181PH/09 Previously, an attempt to use ${perl when it wasn't compiled gave an

3187 PH/42 below, there is no longer a chance of it appearing in a bounce

3206PH/15 Further to TK/02 and TK/03 above, tidied up the tables of what conditions
3207 and controls are allowed in which ACLs. There were a couple of minor
3208 errors. Some of the entries in the conditions table (which is a table of
3209 where they are NOT allowed) were getting very unwieldy; rewrote them as a
3210 negation of where the condition IS allowed.

3214PH/17 The API for radiusclient changed at release 0.4.0. Unfortunately, the
3215 header file does not have a version number, so I've had to invent a new
3216 value for RADIUS_LIB_TYPE, namely "RADIUSCLIENTNEW" to request the new
3217 API. The code is untested by me (my Linux distribution still has 0.3.2 of
3218 radiusclient), but it was contributed by a Radius user.

PH
3223PH/19 When an Exim process that is running as root has to create an Exim log
3224 file, it does so in a subprocess that runs as exim:exim so as to get the
3225 ownership right at creation (otherwise, other Exim processes might see
3226 the file with the wrong ownership). There was no test for failure of this
3227 fork() call, which would lead to the process getting stuck as it waited
3228 for a non-existent subprocess. Forks do occasionally fail when resources
3229 run out. I reviewed all the other calls to fork(); they all seem to check
3230 for failure.

PH
3232PH/20 When checking for unexpected SMTP input at connect time (before writing
3233 the banner), Exim was not dealing correctly with a non-positive return
3234 from the read() function. If the client had disconnected by this time,
3235 the result was a log entry for a synchronization error with an empty
3236 string after "input=" when read() returned zero. If read() returned -1
3237 (an event I could not check), uninitialized data bytes were printed.
3238 There were reports of junk text (parts of files, etc) appearing after
3239 "input=".

3246PH/23 The cyrus_sasl authenticator was expanding server_hostname, but then
3247 forgetting to use the resulting value; it was using the unexpanded value.
3248
c5ddb310
PH
3249PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3250 hadn't been configured. The fix is from Juergen Kreileder, who
3251 understands it better than I do:
3252
3253 "Here's what I see happening with three configured cyrus_sasl
3254 authenticators configured (plain, login, cram-md5):
3255
3256 On startup auth_cyrus_sasl_init() gets called for each of these.
3257 This means three calls to sasl_listmech() without a specified mech_list.
3258 => SASL tests which mechs of all available mechs actually work
3259 => three warnings about OTP not working
3260 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3261
3262 With the patch, sasl_listmech() also gets called three times. But now
3263 SASL's mech_list option is set to the server_mech specified in the the
3264 authenticator. Or in other words, the answer from sasl_listmech()
3265 gets limited to just the mech you're testing for (which is different
3266 for each call.)
3267 => the return list contains just 'plain' or 'login', 'cram-md5' or
3268 nothing depending on the value of ob->server_mech.
3269
3270 I've just tested the patch: Authentication still works fine,
3271 unavailable mechs specified in the exim configuration are still
3272 caught, and the auth.log warnings about OTP are gone."

PH
3282PH/27 $acl_verify_message is now set immediately after the failure of a
3283 verification in an ACL, and so is available in subsequent modifiers. In
3284 particular, the message can be preserved by coding like this:
3285
3286 warn !verify = sender
3287 set acl_m0 = $acl_verify_message

3290 and "log_message" when a very denied access.

PH
3303PH/30 In these circumstances:
3304 . Two addresses routed to the same list of hosts;
3305 . First host does not offer TLS;
3306 . First host accepts first address;
3307 . First host gives temporary error to second address;
3308 . Second host offers TLS and a TLS session is established;
3309 . Second host accepts second address.
3310 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3311 and peerdn, if requested) that were in fact used only for the second
3312 address.

PH
3314PH/31 When doing a callout as part of verifying an address, Exim was not paying
3315 attention to any local part prefix or suffix that was matched by the
3316 router that accepted the address. It now behaves in the same way as it
3317 does for delivery: the affixes are removed from the local part unless
3318 rcpt_include_affixes is set on the transport.

d7174846
PH
3336PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3337 the grounds that routing the same address twice would always produce the
3338 same answer. This might have been true once, but it is certainly no
3339 longer true now. Routing a child address may depend on the previous
3340 routing that produced that child. Some complicated redirection strategies
3341 went wrong when messages had multiple recipients, and made Exim's
3342 behaviour dependent on the order in which the addresses were given.
3343
3344 I have moved the duplicate checking until after the routing is complete.
3345 Exim scans the addresses that are assigned to local and remote
3346 transports, and removes any duplicates. This means that more work will be
3347 done, as duplicates will always all be routed, but duplicates are
3348 presumably rare, so I don't expect this is of any significance.
3349
3350 For deliveries to pipes, files, and autoreplies, the duplicate checking
3351 still happens during the routing process, since they are not going to be
3352 routed further.

3354PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3355 It corrects a timeout issue with spamd. This is Ian's comment: "The
3356 background is that sometimes spamd either never reads data from a
3357 connection it has accepted, or it never writes response data. The exiscan
3358 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3359 blindly assumes that writes won't block so it may never time out."
