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.

210TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
211
212 When a queue runner is handling a message, Exim first routes the
213 recipient addresses, during which it prunes them based on the retry
214 hints database. After that it attempts to deliver the message to
215 any remaining recipients. It then updates the hints database using
216 the retry rules.
217
218 So if a recipient address works intermittently, it can get repeatedly
219 deferred at routing time. The retry hints record remains fresh so the
220 address never reaches the final cutoff time.
221
222 This is a fairly common occurrence when a user is bumping up against
223 their storage quota. Exim had some logic in its local delivery code
224 to deal with this. However it did not apply to per-recipient defers
225 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
226
1ddeb334
TF
227 This change adds a proper retry rule check during routing so that the
228 final cutoff time is checked against the message's age. We only do
229 this check if there is an address retry record and there is not a
230 domain retry record; this implies that previous attempts to handle
231 the address had the retry_use_local_parts option turned on. We use
232 this as an approximation for the destination being like a local
233 delivery, as in LMTP.
67bd1ab3
TF
234
235 I suspect this new check makes the old local delivery cutoff check
236 redundant, but I have not verified this so I left the code in place.

239
240 Test 0254 submits a message to Exim with the header
241
242 Resent-From: f
243
244 When I ran the test suite under the user fanf2, Exim expanded
245 the header to contain my full name, whereas it should have added
246 a Resent-Sender: header. It erroneously treats any prefix of the
247 username as equal to the username.
248
249 This change corrects that bug.

270JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
271 Server implementation by Todd Lyons, client by JH.
272 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
273 config variable "prdr_enable" controls whether the server
274 advertises the facility. If the client requests PRDR a new
275 acl_data_smtp_prdr ACL is called once for each recipient, after
276 the body content is received and before the acl_smtp_data ACL.
277 The client is controlled by bolth of: a hosts_try_prdr option
278 on the smtp transport, and the server advertisement.
279 Default client logging of deliveries and rejections involving
280 PRDR are flagged with the string "PRDR".

558TF/03 Make the exiwhat support code safe for signals. Previously Exim might
559 lock up or crash if it happened to be inside a call to libc when it
560 got a SIGUSR1 from exiwhat.
561
562 The SIGUSR1 handler appends the current process status to the process
563 log which is later printed by exiwhat. It used to use the general
564 purpose logging code to do this, but several functions it calls are
565 not safe for signals.
566
567 The new output code in the SIGUSR1 handler is specific to the process
568 log, and simple enough that it's easy to inspect for signal safety.
569 Removing some special cases also simplifies the general logging code.
570 Removing the spurious timestamps from the process log simplifies
571 exiwhat.
572
c99ce5c9
TF
573TF/04 Improved ratelimit ACL condition.
574
575 The /noupdate option has been deprecated in favour of /readonly which
576 has clearer semantics. The /leaky, /strict, and /readonly update modes
577 are mutually exclusive. The update mode is no longer included in the
578 database key; it just determines when the database is updated. (This
579 means that when you upgrde Exim will forget old rate measurements.)
580
581 Exim now checks that the per_* options are used with an update mode that
582 makes sense for the current ACL. For example, when Exim is processing a
583 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
584 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
585 must specify per_mail/readonly. If you omit the update mode it defaults to
586 /leaky where that makes sense (as before) or /readonly where required.
587
588 The /noupdate option is now undocumented but still supported for
589 backwards compatibility. It is equivalent to /readonly except that in
590 ACLs where /readonly is required you may specify /leaky/noupdate or
591 /strict/noupdate which are treated the same as /readonly.
592
593 A useful new feature is the /count= option. This is a generalization
594 of the per_byte option, so that you can measure the throughput of other
595 aggregate values. For example, the per_byte option is now equivalent
596 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
597
598 The per_rcpt option has been generalized using the /count= mechanism
599 (though it's more complicated than the per_byte equivalence). When it is
600 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
601 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
602 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
603 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
604 Note that using per_rcpt with a non-readonly update mode in more than
605 one ACL will cause the recipients to be double-counted. (The per_mail
606 and per_byte options don't have this problem.)
607
608 The handling of very low rates has changed slightly. If the computed rate
609 is less than the event's count (usually one) then this event is the first
610 after a long gap. In this case the rate is set to the same as this event's
611 count, so that the first message of a spam run is counted properly.
612
613 The major new feature is a mechanism for counting the rate of unique
614 events. The new per_addr option counts the number of different
615 recipients that someone has sent messages to in the last time period. It
616 behaves like per_rcpt if all the recipient addresses are different, but
617 duplicate recipient addresses do not increase the measured rate. Like
618 the /count= option this is a general mechanism, so the per_addr option
619 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
620 example, measure the rate that a client uses different sender addresses
621 with the options per_mail/unique=$sender_address. There are further
622 details in the main documentation.

PH
1196PH/02 When an IPv6 address is converted to a string for single-key lookup
1197 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1198 dots are used instead of colons so that keys in lsearch files need not
1199 contain colons. This was done some time before quoting was made available
1200 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1201 (notated using the quote facility) so as to distinguish them from IPv4
1202 keys. This meant that lookups for IP addresses in host lists did not work
1203 for iplsearch lookups.
1204
1205 This has been fixed by arranging for IPv6 addresses to be expressed with
1206 colons if the lookup type is iplsearch. This is not incompatible, because
1207 previously such lookups could never work.
1208
1209 The situation is now rather anomolous, since one *can* have colons in
1210 ordinary lsearch keys. However, making the change in all cases is
1211 incompatible and would probably break a number of configurations.

1216MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1217 conversion specification without a maximum field width, thereby enabling
1218 a rogue spamd server to cause a buffer overflow. While nobody in their
1219 right mind would setup Exim to query an untrusted spamd server, an
1220 attacker that gains access to a server running spamd could potentially
1221 exploit this vulnerability to run arbitrary code as the Exim user.

1226MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1227 a directory entry by the name of the lookup key. Previously, if a
1228 symlink pointed to a non-existing file or a file in a directory that
1229 Exim lacked permissions to read, a lookup for a key matching that

1414PH/29 SMTP synchronization checks are implemented when a command is read -
1415 there is a check that no more input is waiting when there shouldn't be

1417 some time before the response is written. In this time, more input might
1418 arrive, invalidly. So now there are extra checks after an ACL has run for
1419 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1420 pipelining has not been advertised.

1435 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1436 was a macro that became an assignment, so it seemed to work. This has

PH
1494 the response to the final '.' that terminates a message, but only in the
1495 case where the client has not sent further data following the '.'
1496 (unfortunately, this is allowed). However, in many cases there won't be
1497 any further data because there won't be any more messages to send. A call
1498 to select() can be used: if it shows that the input is "ready", there is
1499 either input waiting, or the socket has been closed. An attempt to read
1500 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1501 would have sent an OK response which the client would never have see.

1512PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1513 fixed by 4.65/MH/01 (is this a record?) are fixed:
1514
1515 (i) An empty string was always treated as zero by the numeric comparison
1516 operators. This behaviour has been restored.
1517
1518 (ii) It is documented that the numeric comparison operators always treat
1519 their arguments as decimal numbers. This was broken in that numbers
1520 starting with 0 were being interpreted as octal.
1521
1522 While fixing these problems I realized that there was another issue that
1523 hadn't been noticed. Values of message_size_limit (both the global option
1524 and the transport option) were treated as octal if they started with 0.
1525 The documentation was vague. These values are now always treated as
1526 decimal, and I will make that clear in the documentation.

PH
1570PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1571 callout verification, Exim cached a "reject" for the entire domain. This
1572 is correct for most verifications, but it is not correct for a recipient
1573 verification with use_sender or use_postmaster set, because in that case
1574 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1575 case of MAIL FROM:<> rejection from other early rejections (e.g.
1576 rejection of HELO). When verifying a recipient using a non-null MAIL
1577 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1578 Whatever the result of the callout, the value of the domain cache is
1579 left unchanged (for any other kind of callout, getting as far as trying
1580 RCPT means that the domain itself is ok).

1614PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1615 hostname. This is wrong, because it relates to the incoming message (and
1616 probably the interface on which it is arriving) and not to the outgoing
1617 callout (which could be using a different interface). This has been
1618 changed to use the value of the helo_data option from the smtp transport
1619 instead - this is what is used when a message is actually being sent. If
1620 there is no remote transport (possible with a router that sets up host
1621 addresses), $smtp_active_hostname is used.

14aa5a05 1623PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1624 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1625 (a) The code assumed that strncpy() returns a negative number on buffer
1626 overflow, which isn't the case. Replaced with Exim's string_format()
1627 function.
1628 (b) There were several signed/unsigned issues. I just did the minimum
1629 hacking in of casts. There is scope for a larger refactoring.
1630 (c) The code used strcasecmp() which is not a standard C function.
1631 Replaced with Exim's strcmpic() function.
1632 (d) The code set only $1; it now sets $auth1 as well.
1633 (e) A simple test gave the error "authentication client didn't specify
1634 service in request". It would seem that Dovecot has changed its
1635 interface. Fortunately there's a specification; I followed it and
1636 changed what the client sends and it appears to be working now.

1641PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1642 address A is aliased to B and C, where B exists and C does not. Without
1643 -v the output is "A verified" because verification stops after a
1644 successful redirection if more than one address is generated. However,
1645 with -v the child addresses are also verified. Exim was outputting "A
1646 failed to verify" and then showing the successful verification for C,
1647 with its parentage. It now outputs "B failed to verify", showing B's
1648 parentage before showing the successful verification of C.

1653
322050c2
PH
1654PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1655 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1656 they consult the DNS. I had assumed they would set it the way they
1657 wanted; and indeed my experiments on Linux seem to show that in some
1658 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1659 To be on the safe side, however, I have now made the interface to
1660 host_find_byname() similar to host_find_bydns(), with an argument
1661 containing the DNS resolver options. The host_find_byname() function now
1662 sets these options at its start, just as host_find_bydns() does. The smtp
1663 transport options dns_qualify_single and dns_search_parents are passed to
1664 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1665 of host_find_byname() use the default settings of RES_DEFNAMES
1666 (qualify_single) but not RES_DNSRCH (search_parents).
1667

PH
1668PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1669 spool_read_header() do less string testing, by means of a preliminary
1670 switch on the second character of optional "-foo" lines. (This is
1671 overdue, caused by the large number of possibilities that now exist.
1672 Originally there were few.) While I was there, I also converted the
1673 str(n)cmp tests so they don't re-test the leading "-" and the first
1674 character, in the hope this might squeeze out yet more improvement.
1675

PH
1676PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1677 flag allowing group syntax was set by the header_syntax check but not
1678 turned off, possible causing trouble later; (2) The flag was not being
1679 set at all for the header_verify test, causing "group"-style headers to
1680 be rejected. I have now set it in this case, and also caused header_
1681 verify to ignore an empty address taken from a group. While doing this, I
1682 came across some other cases where the code for allowing group syntax
1683 while scanning a header line wasn't quite right (mostly, not resetting
1684 the flag correctly in the right place). These bugs could have caused
1685 trouble for malformed header lines. I hope it is now all correct.
1686
602e59e5
PH
1687PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1688 with the "reply" argument non-NULL. The code, however (which originally
1689 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1690 but it didn't always do it. This confused somebody who was copying the
1691 code for some other use. I have removed all the tests.
1692
411ef850
PH
1693PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1694 feature that was used to support insecure browsers during the U.S. crypto
1695 embargo. It requires special client support, and Exim is probably the
1696 only MTA that supported it -- and would never use it because real RSA is
1697 always available. This code has been removed, because it had the bad
1698 effect of slowing Exim down by computing (never used) parameters for the
1699 RSA_EXPORT functionality.

PH
1701PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1702 authenticator to fail if there's a tab character in the incoming data
1703 (there should never be unless someone is messing about, as it's supposed
1704 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1705 if the connection is using TLS or if the remote IP is the same as the
1706 local IP, and the "valid-client-cert option" if a client certificate has
1707 been verified.

1738
1739PH/30 Exim was sometimes attempting to deliver messages that had suffered
1740 address errors (4xx response to RCPT) over the same connection as other
1741 messages routed to the same hosts. Such deliveries are always "forced",
1742 so retry times are not inspected. This resulted in far too many retries
1743 for the affected addresses. The effect occurred only when there were more
1744 hosts than the hosts_max_try setting in the smtp transport when it had
1745 the 4xx errors. Those hosts that it had tried were not added to the list
1746 of hosts for which the message was waiting, so if all were tried, there
1747 was no problem. Two fixes have been applied:
1748
1749 (i) If there are any address or message errors in an SMTP delivery, none
1750 of the hosts (tried or untried) are now added to the list of hosts
1751 for which the message is waiting, so the message should not be a
1752 candidate for sending over the same connection that was used for a
1753 successful delivery of some other message. This seems entirely
1754 reasonable: after all the message is NOT "waiting for some host".
1755 This is so "obvious" that I'm not sure why it wasn't done
1756 previously. Hope I haven't missed anything, but it can't do any
1757 harm, as the worst effect is to miss an optimization.
1758
1759 (ii) If, despite (i), such a delivery is accidentally attempted, the
1760 routing retry time is respected, so at least it doesn't keep
1761 hammering the server.

1776PH/35 The error "getsockname() failed: connection reset by peer" was being
1777 written to the panic log as well as the main log, but it isn't really
1778 panic-worthy as it just means the connection died rather early on. I have
1779 removed the panic log writing for the ECONNRESET error when getsockname()
1780 fails.
1781
48c7f9e2
PH
1782PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1783 runs only) independently of the message's sender address. This meant
1784 that, if the 4xx error was in fact related to the sender, a different
1785 message to the same recipient with a different sender could confuse
1786 things. In particualar, this can happen when sending to a greylisting
1787 server, but other circumstances could also provoke similar problems.
1788 I have changed the default so that the retry time for these errors is now
1789 based a combination of the sender and recipient addresses. This change
1790 can be overridden by setting address_retry_include_sender=false in the
1791 smtp transport.

2059PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
2060 "Deny" causes Exim to reject the incoming connection with a 554 error.
2061 Unfortunately, if there is a major crisis, such as a disk failure,
2062 tcp-wrappers gives "deny", whereas what one would like would be some
2063 kind of temporary error. A kludge has been added to help with this.
2064 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2065 554 error is used if errno is still zero or contains ENOENT (which occurs
2066 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2067 451 error is used.

2103PH/01 The code for finding all the local interface addresses on a FreeBSD
2104 system running IPv6 was broken. This may well have applied to all BSD
2105 systems, as well as to others that have similar system calls. The broken
2106 code found IPv4 interfaces correctly, but gave incorrect values for the
2107 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2108 that it would not match correctly against @[] and not recognize the IPv6
2109 addresses as local.

2152 autoreply, Exim could try to deliver to a non-existent relative file

2173 changes:
2174
2175 (a) Failures to set uid/gid, the current directory, or a process leader
2176 in a subprocess such as that created by queryprogram now generate
2177 suitable debugging ouput when -d is set.
2178

2181 the subprocess without attempting to change uid/gid.

2186PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2187 additional section of a DNS packet that returns MX or SRV records.
2188 Instead, it always explicitly searches for A/AAAA records. This avoids
2189 major problems that occur when a DNS server includes only records of one
2190 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2191 fixed another bug: if SRV records were looked up and the corresponding
2192 address records were *not* found in the additional section, the port
2193 values from the SRV records were lost.

2195PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2203PH/19 When calculating a retry time, Exim used to measure the "time since
2204 failure" by looking at the "first failed" field in the retry record. Now
2205 it does not use this if it is later than than the arrival time of the
2206 message. Instead it uses the arrival time. This makes for better
2207 behaviour in cases where some deliveries succeed, thus re-setting the
2208 "first failed" field. An example is a quota failure for a huge message
2209 when small messages continue to be delivered. Without this change, the
2210 "time since failure" will always be short, possible causing more frequent
2211 delivery attempts for the huge message than are intended.

2308PH/42 The content-scanning code uses fopen() to create files in which to put

2311 files with open(), and sets the required mode explicitly. Thus, these
2312 files were ending up world-writeable. This was not a big issue, because,
2313 being within the spool directory, they were not world-accessible. I have
2314 created a function called modefopen, which takes an additional mode
2315 argument. It sets umask(777), creates the file, chmods it to the required
2316 mode, then resets the umask. All the relevant calls to fopen() in the

2352PH/52 Two bugs concerned with error handling when the smtp transport is
2353 used in LMTP mode:
2354
2355 (i) Exim was not creating retry information for temporary errors given
2356 for individual recipients after the DATA command when the smtp transport
2357 was used in LMTP mode. This meant that they could be retried too
2358 frequently, and not timed out correctly.
2359
2360 (ii) Exim was setting the flag that allows error details to be returned
2361 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2362 recipients that were returned after the DATA command.
2363
2364PH/53 This is related to PH/52, but is more general: for any failing address,
2365 when detailed error information was permitted to be returned to the
2366 sender, but the error was temporary, then after the final timeout, only
2367 "retry timeout exceeded" was returned. Now it returns the full error as
2368 well as "retry timeout exceeded".

2424PH/68 The bounce_return_message and bounce_return_body options were not being
2425 honoured for bounces generated during the reception of non-SMTP messages.
2426 In particular, this applied to messages rejected by the ACL. This bug has
2427 been fixed. However, if bounce_return_message is true and bounce_return_
2428 body is false, the headers that are returned for a non-SMTP message
2429 include only those that have been read before the error was detected.

PH
2438PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2439 function verify_get_ident() calls ip_connect() to connect a socket, but
2440 if the "connect()" function timed out, ip_connect() used to close the
2441 socket. However, verify_get_ident() also closes the socket later, and in
2442 between Exim writes to the log, which may get opened at this point. When
2443 the socket was closed in ip_connect(), the log could get the same file
2444 descriptor number as the socket. This naturally causes chaos. The fix is
2445 not to close the socket in ip_connect(); the socket should be closed by
2446 the function that creates it. There was only one place in the code where
2447 this was missing, in the iplookup router, which I don't think anybody now
2448 uses, but I've fixed it anyway.

2467PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2468
2469 (1) Generate an error if the third argument for the ${prvs expansion is
2470 not a single digit.
2471
2472 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2473 string.
2474
2475 (3) Reset the variables that are obtained from the first argument of
2476 ${prvscheck and used in the second argument before leaving the code,
2477 because their memory is reclaimed, so using them afterwards may do
2478 silly things.
2479
2480 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2481 one (it's much easier than Tom thought :-).
2482
2483 (5) Because of (4), we can now allow for the use of $prvscheck_result
2484 inside the third argument.

2494 quoted in the delivery log line, like this:
2495
2496 => >A.N.Other <ano@some.domain> <original@ddress> ...
2497
2498 This has been changed so that it extracts the operative address. There
2499 may be more than one such address. If so, they are comma-separated, like
2500 this:
2501
2502 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2504PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2505 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2506 not being looked up in the rDNS to get a host name, Exim was showing the
2507 IP address twice in Received: lines, even though the IP addresses were
2508 identical. For example:
2509
2510 Received: from [1.2.3.4] (helo=[1.2.3.4])
2511
2512 However, if the real host name was known, it was omitting the HELO data
2513 if it matched the actual IP address. This has been tidied up so that it
2514 doesn't show the same IP address twice.

2516PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2540PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2541 Electronic Mail") by including:
2542
2543 Auto-submitted: auto-generated
2544
2545 in the messages that it generates (bounce messages and others, such as
2546 warnings). In the case of bounce messages for non-SMTP mesages, there was
2547 also a typo: it was using "Auto_submitted" (underscore instead of
2548 hyphen). Since every message generated by Exim is necessarily in response
2549 to another message, thes have all been changed to:
2550
2551 Auto-Submitted: auto-replied
2552
2553 in accordance with these statements in the RFC:
2554
2555 The auto-replied keyword:
2556
2557 - SHOULD be used on messages sent in direct response to another
2558 message by an automatic process,
2559
2560 - MUST NOT be used on manually-generated messages,
2561
2562 - MAY be used on Delivery Status Notifications (DSNs) and Message
2563 Disposition Notifications (MDNs),
2564
2565 - MUST NOT be used on messages generated by automatic or periodic
2566 processes, except for messages which are automatic responses to
2567 other messages.

PH
2603PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2604 canonical form (as documented). However, after a host name lookup from
2605 the IP address, check_host() was doing a simple string comparison with
2606 addresses acquired from the DNS when checking that the found name did
2607 have the original IP as one of its addresses. Since any found IPv6
2608 addresses are likely to be in abbreviated form, the comparison could
2609 fail. Luckily, there already exists a function for doing the comparison
2610 by converting both addresses to binary, so now that is used instead of
2611 the text comparison.
2612
96776534
PH
2613PH/20 There was another similar case to PH/19, when a complete host name was

2909 with the definition in sysexits.h (which is #included earlier).
2910 Fortunately, Exim does not actually use EX_OK. The code used to try to
2911 preserve the sysexits.h value, by assumimg that macro definitions were
2912 scanned for macro replacements. I have been disabused of this notion,
2913 so now the code just undefines EX_OK before #including unistd.h.

2918 This seems wrong - if the receiver was accepting one byte at a time it
2919 would take for ever. The timeout is now adjusted when this happens. It
2920 doesn't have to be particularly precise.

2995 the logs files are, rather than using the compiled in default. In our
2996 case the guess is not the same as the compiled default, so the script
2997 suddenly stopped working when I started to use syslog. The patch checks
2998 to see if log_file_path is "". If so, it attempts to read it from exim

3000 falls back to the previous guessing code."

3128
3129PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3130 that changes the way the GnuTLS parameters are stored in the cache file.
3131 The new format can be generated externally. For backward compatibility,
3132 if the data in the cache doesn't make sense, Exim assumes it has read an
3133 old-format file, and it generates new data and writes a new file. This
3134 means that you can't go back to an older release without removing the
3135 file.
3136
3137PH/03 A redirect router that has both "unseen" and "one_time" set does not
3138 work if there are any delivery delays because "one_time" forces the
3139 parent to be marked "delivered", so its unseen clone is never tried
3140 again. For this reason, Exim now forbids the simultaneous setting of
3141 these two options.
3142
3143PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3144 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3145 entry if you want to know the details. The fix, however, neglected to
3146 consider the case when local delivery batching is involved. The test for
3147 "previously delivered" was not happening when checking to see if an
3148 address could be batched with a previous (undelivered) one; under
3149 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3150 address.

PH
3151
3152PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3155PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3156 header_syntax) but Exim was just ignoring anything given after a slash.
3157 In particular, this caused confusion with an attempt to use "verify =
3158 reverse_host_lookup/defer_ok". An error is now given when options are
3159 supplied for verify items that do not have them. (Maybe reverse_host_
3160 lookup should have a defer_ok option, but that's a different point.)

3162PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3212PH/19 When an Exim process that is running as root has to create an Exim log
3213 file, it does so in a subprocess that runs as exim:exim so as to get the
3214 ownership right at creation (otherwise, other Exim processes might see
3215 the file with the wrong ownership). There was no test for failure of this
3216 fork() call, which would lead to the process getting stuck as it waited
3217 for a non-existent subprocess. Forks do occasionally fail when resources
3218 run out. I reviewed all the other calls to fork(); they all seem to check
3219 for failure.

3221PH/20 When checking for unexpected SMTP input at connect time (before writing

3223 from the read() function. If the client had disconnected by this time,
3224 the result was a log entry for a synchronization error with an empty
3225 string after "input=" when read() returned zero. If read() returned -1
3226 (an event I could not check), uninitialized data bytes were printed.

3237
c5ddb310
PH
3238PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3239 hadn't been configured. The fix is from Juergen Kreileder, who
3240 understands it better than I do:
3241
3242 "Here's what I see happening with three configured cyrus_sasl
3243 authenticators configured (plain, login, cram-md5):
3244
3245 On startup auth_cyrus_sasl_init() gets called for each of these.
3246 This means three calls to sasl_listmech() without a specified mech_list.
3247 => SASL tests which mechs of all available mechs actually work
3248 => three warnings about OTP not working
3249 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3250
3251 With the patch, sasl_listmech() also gets called three times. But now
3252 SASL's mech_list option is set to the server_mech specified in the the
3253 authenticator. Or in other words, the answer from sasl_listmech()
3254 gets limited to just the mech you're testing for (which is different
3255 for each call.)
3256 => the return list contains just 'plain' or 'login', 'cram-md5' or
3257 nothing depending on the value of ob->server_mech.
3258
3259 I've just tested the patch: Authentication still works fine,
3260 unavailable mechs specified in the exim configuration are still
3261 caught, and the auth.log warnings about OTP are gone."

3297 . Second host offers TLS and a TLS session is established;

PH
3325PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3326 the grounds that routing the same address twice would always produce the
3327 same answer. This might have been true once, but it is certainly no
3328 longer true now. Routing a child address may depend on the previous
3329 routing that produced that child. Some complicated redirection strategies
3330 went wrong when messages had multiple recipients, and made Exim's
3331 behaviour dependent on the order in which the addresses were given.
3332
3333 I have moved the duplicate checking until after the routing is complete.
3334 Exim scans the addresses that are assigned to local and remote
3335 transports, and removes any duplicates. This means that more work will be
3336 done, as duplicates will always all be routed, but duplicates are
3337 presumably rare, so I don't expect this is of any significance.
3338
3339 For deliveries to pipes, files, and autoreplies, the duplicate checking
3340 still happens during the routing process, since they are not going to be
3341 routed further.

3346 connection it has accepted, or it never writes response data. The exiscan
3347 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3348 blindly assumes that writes won't block so it may never time out."
