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

46JH/05 Fix results-pipe from transport process. Several recipients, combined
47 with certificate use, exposed issues where response data items split
48 over buffer boundaries were not parsed properly. This eventually
49 resulted in duplicates being sent. This issue only became common enough
50 to notice due to the introduction of conection certificate information,
51 the item size being so much larger. Found and fixed by Wolfgang Breyha.

61 is EXPERIMENTAL_EVENT, the main-configuration and transport options

aec45841 63 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
64 routers, transports and related events. The tls:cert event is now also
65 raised for inbound connections, if the main configuration event_action
66 option is defined.

123TF/01 Correctly close the server side of TLS when forking for delivery.
124
125 When a message was received over SMTP with TLS, Exim failed to clear up
126 the incoming connection properly after forking off the child process to
127 deliver the message. In some situations the subsequent outgoing
128 delivery connection happened to have the same fd number as the incoming
129 connection previously had. Exim would try to use TLS and fail, logging
130 a "Bad file descriptor" error.

376TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
377
378 When a queue runner is handling a message, Exim first routes the
379 recipient addresses, during which it prunes them based on the retry
380 hints database. After that it attempts to deliver the message to
381 any remaining recipients. It then updates the hints database using
382 the retry rules.
383
384 So if a recipient address works intermittently, it can get repeatedly
385 deferred at routing time. The retry hints record remains fresh so the
386 address never reaches the final cutoff time.
387
388 This is a fairly common occurrence when a user is bumping up against
389 their storage quota. Exim had some logic in its local delivery code
390 to deal with this. However it did not apply to per-recipient defers
391 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
392
1ddeb334
TF
393 This change adds a proper retry rule check during routing so that the
394 final cutoff time is checked against the message's age. We only do
395 this check if there is an address retry record and there is not a
396 domain retry record; this implies that previous attempts to handle
397 the address had the retry_use_local_parts option turned on. We use
398 this as an approximation for the destination being like a local
399 delivery, as in LMTP.
67bd1ab3
TF
400
401 I suspect this new check makes the old local delivery cutoff check
402 redundant, but I have not verified this so I left the code in place.

409
410 When I ran the test suite under the user fanf2, Exim expanded
411 the header to contain my full name, whereas it should have added
412 a Resent-Sender: header. It erroneously treats any prefix of the
413 username as equal to the username.
414
415 This change corrects that bug.

436JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
437 Server implementation by Todd Lyons, client by JH.
438 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
439 config variable "prdr_enable" controls whether the server
440 advertises the facility. If the client requests PRDR a new
441 acl_data_smtp_prdr ACL is called once for each recipient, after
442 the body content is received and before the acl_smtp_data ACL.
443 The client is controlled by bolth of: a hosts_try_prdr option
444 on the smtp transport, and the server advertisement.
445 Default client logging of deliveries and rejections involving
446 PRDR are flagged with the string "PRDR".

724TF/03 Make the exiwhat support code safe for signals. Previously Exim might
725 lock up or crash if it happened to be inside a call to libc when it
726 got a SIGUSR1 from exiwhat.
727
728 The SIGUSR1 handler appends the current process status to the process
729 log which is later printed by exiwhat. It used to use the general
730 purpose logging code to do this, but several functions it calls are
731 not safe for signals.
732
733 The new output code in the SIGUSR1 handler is specific to the process
734 log, and simple enough that it's easy to inspect for signal safety.
735 Removing some special cases also simplifies the general logging code.
736 Removing the spurious timestamps from the process log simplifies
737 exiwhat.
738
c99ce5c9
TF
739TF/04 Improved ratelimit ACL condition.
740
741 The /noupdate option has been deprecated in favour of /readonly which
742 has clearer semantics. The /leaky, /strict, and /readonly update modes
743 are mutually exclusive. The update mode is no longer included in the
744 database key; it just determines when the database is updated. (This
745 means that when you upgrde Exim will forget old rate measurements.)
746
747 Exim now checks that the per_* options are used with an update mode that
748 makes sense for the current ACL. For example, when Exim is processing a
749 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
750 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
751 must specify per_mail/readonly. If you omit the update mode it defaults to
752 /leaky where that makes sense (as before) or /readonly where required.
753
754 The /noupdate option is now undocumented but still supported for
755 backwards compatibility. It is equivalent to /readonly except that in
756 ACLs where /readonly is required you may specify /leaky/noupdate or
757 /strict/noupdate which are treated the same as /readonly.
758
759 A useful new feature is the /count= option. This is a generalization
760 of the per_byte option, so that you can measure the throughput of other
761 aggregate values. For example, the per_byte option is now equivalent
762 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
763
764 The per_rcpt option has been generalized using the /count= mechanism
765 (though it's more complicated than the per_byte equivalence). When it is
766 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
767 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
768 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
769 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
770 Note that using per_rcpt with a non-readonly update mode in more than
771 one ACL will cause the recipients to be double-counted. (The per_mail
772 and per_byte options don't have this problem.)
773
774 The handling of very low rates has changed slightly. If the computed rate
775 is less than the event's count (usually one) then this event is the first
776 after a long gap. In this case the rate is set to the same as this event's
777 count, so that the first message of a spam run is counted properly.
778
779 The major new feature is a mechanism for counting the rate of unique
780 events. The new per_addr option counts the number of different
781 recipients that someone has sent messages to in the last time period. It
782 behaves like per_rcpt if all the recipient addresses are different, but
783 duplicate recipient addresses do not increase the measured rate. Like
784 the /count= option this is a general mechanism, so the per_addr option
785 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
786 example, measure the rate that a client uses different sender addresses
787 with the options per_mail/unique=$sender_address. There are further
788 details in the main documentation.

1339 were called 'true' and it seems that C99 defines that as a reserved

1358-----------------
1359
1360PH/01 Another patch from the Sieve maintainer.
1361
6a3bceb1
PH
1362PH/02 When an IPv6 address is converted to a string for single-key lookup
1363 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1364 dots are used instead of colons so that keys in lsearch files need not
1365 contain colons. This was done some time before quoting was made available
1366 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1367 (notated using the quote facility) so as to distinguish them from IPv4
1368 keys. This meant that lookups for IP addresses in host lists did not work
1369 for iplsearch lookups.
1370
1371 This has been fixed by arranging for IPv6 addresses to be expressed with
1372 colons if the lookup type is iplsearch. This is not incompatible, because
1373 previously such lookups could never work.
1374
1375 The situation is now rather anomolous, since one *can* have colons in
1376 ordinary lsearch keys. However, making the change in all cases is
1377 incompatible and would probably break a number of configurations.

MH
1382MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1383 conversion specification without a maximum field width, thereby enabling
1384 a rogue spamd server to cause a buffer overflow. While nobody in their
1385 right mind would setup Exim to query an untrusted spamd server, an
1386 attacker that gains access to a server running spamd could potentially
1387 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1392MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1393 a directory entry by the name of the lookup key. Previously, if a
1394 symlink pointed to a non-existing file or a file in a directory that
1395 Exim lacked permissions to read, a lookup for a key matching that
1396 symlink would fail. Now it is enough that a matching directory entry
1397 exists, symlink or not. (Bugzilla 503.)

1581 there is a check that no more input is waiting when there shouldn't be
1582 any. However, for some commands, a delay in an ACL can mean that it is
1583 some time before the response is written. In this time, more input might
1584 arrive, invalidly. So now there are extra checks after an ACL has run for
1585 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1586 pipelining has not been advertised.

1601 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1602 was a macro that became an assignment, so it seemed to work. This has
1603 changed to a proper function call with a void return, hence the compile

1660 the response to the final '.' that terminates a message, but only in the
1661 case where the client has not sent further data following the '.'
1662 (unfortunately, this is allowed). However, in many cases there won't be
1663 any further data because there won't be any more messages to send. A call
1664 to select() can be used: if it shows that the input is "ready", there is
1665 either input waiting, or the socket has been closed. An attempt to read
1666 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1667 would have sent an OK response which the client would never have see.

1678PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1679 fixed by 4.65/MH/01 (is this a record?) are fixed:
1680
1681 (i) An empty string was always treated as zero by the numeric comparison
1682 operators. This behaviour has been restored.
1683
1684 (ii) It is documented that the numeric comparison operators always treat
1685 their arguments as decimal numbers. This was broken in that numbers
1686 starting with 0 were being interpreted as octal.
1687
1688 While fixing these problems I realized that there was another issue that
1689 hadn't been noticed. Values of message_size_limit (both the global option
1690 and the transport option) were treated as octal if they started with 0.
1691 The documentation was vague. These values are now always treated as
1692 decimal, and I will make that clear in the documentation.

PH
1736PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1737 callout verification, Exim cached a "reject" for the entire domain. This
1738 is correct for most verifications, but it is not correct for a recipient
1739 verification with use_sender or use_postmaster set, because in that case
1740 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1741 case of MAIL FROM:<> rejection from other early rejections (e.g.
1742 rejection of HELO). When verifying a recipient using a non-null MAIL
1743 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1744 Whatever the result of the callout, the value of the domain cache is
1745 left unchanged (for any other kind of callout, getting as far as trying
1746 RCPT means that the domain itself is ok).

1782 probably the interface on which it is arriving) and not to the outgoing
1783 callout (which could be using a different interface). This has been
1784 changed to use the value of the helo_data option from the smtp transport
1785 instead - this is what is used when a message is actually being sent. If
1786 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
1791 (a) The code assumed that strncpy() returns a negative number on buffer
1792 overflow, which isn't the case. Replaced with Exim's string_format()
1793 function.
1794 (b) There were several signed/unsigned issues. I just did the minimum
1795 hacking in of casts. There is scope for a larger refactoring.
1796 (c) The code used strcasecmp() which is not a standard C function.
1797 Replaced with Exim's strcmpic() function.
1798 (d) The code set only $1; it now sets $auth1 as well.
1799 (e) A simple test gave the error "authentication client didn't specify
1800 service in request". It would seem that Dovecot has changed its
1801 interface. Fortunately there's a specification; I followed it and
1802 changed what the client sends and it appears to be working now.

1808 address A is aliased to B and C, where B exists and C does not. Without
1809 -v the output is "A verified" because verification stops after a
1810 successful redirection if more than one address is generated. However,
1811 with -v the child addresses are also verified. Exim was outputting "A
1812 failed to verify" and then showing the successful verification for C,
1813 with its parentage. It now outputs "B failed to verify", showing B's
1814 parentage before showing the successful verification of C.

PH
1820PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1821 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1822 they consult the DNS. I had assumed they would set it the way they
1823 wanted; and indeed my experiments on Linux seem to show that in some
1824 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1825 To be on the safe side, however, I have now made the interface to
1826 host_find_byname() similar to host_find_bydns(), with an argument
1827 containing the DNS resolver options. The host_find_byname() function now
1828 sets these options at its start, just as host_find_bydns() does. The smtp
1829 transport options dns_qualify_single and dns_search_parents are passed to
1830 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1831 of host_find_byname() use the default settings of RES_DEFNAMES
1832 (qualify_single) but not RES_DNSRCH (search_parents).

1835 spool_read_header() do less string testing, by means of a preliminary
1836 switch on the second character of optional "-foo" lines. (This is
1837 overdue, caused by the large number of possibilities that now exist.
1838 Originally there were few.) While I was there, I also converted the
1839 str(n)cmp tests so they don't re-test the leading "-" and the first
1840 character, in the hope this might squeeze out yet more improvement.

1842PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1843 flag allowing group syntax was set by the header_syntax check but not
1844 turned off, possible causing trouble later; (2) The flag was not being
1845 set at all for the header_verify test, causing "group"-style headers to
1846 be rejected. I have now set it in this case, and also caused header_
1847 verify to ignore an empty address taken from a group. While doing this, I
1848 came across some other cases where the code for allowing group syntax
1849 while scanning a header line wasn't quite right (mostly, not resetting
1850 the flag correctly in the right place). These bugs could have caused
1851 trouble for malformed header lines. I hope it is now all correct.

1853PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

PH
1859PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1860 feature that was used to support insecure browsers during the U.S. crypto
1861 embargo. It requires special client support, and Exim is probably the
1862 only MTA that supported it -- and would never use it because real RSA is
1863 always available. This code has been removed, because it had the bad
1864 effect of slowing Exim down by computing (never used) parameters for the
1865 RSA_EXPORT functionality.

1872 local IP, and the "valid-client-cert option" if a client certificate has

PH
1904
1905PH/30 Exim was sometimes attempting to deliver messages that had suffered
1906 address errors (4xx response to RCPT) over the same connection as other
1907 messages routed to the same hosts. Such deliveries are always "forced",
1908 so retry times are not inspected. This resulted in far too many retries
1909 for the affected addresses. The effect occurred only when there were more
1910 hosts than the hosts_max_try setting in the smtp transport when it had
1911 the 4xx errors. Those hosts that it had tried were not added to the list
1912 of hosts for which the message was waiting, so if all were tried, there
1913 was no problem. Two fixes have been applied:
1914
1915 (i) If there are any address or message errors in an SMTP delivery, none
1916 of the hosts (tried or untried) are now added to the list of hosts
1917 for which the message is waiting, so the message should not be a
1918 candidate for sending over the same connection that was used for a
1919 successful delivery of some other message. This seems entirely
1920 reasonable: after all the message is NOT "waiting for some host".
1921 This is so "obvious" that I'm not sure why it wasn't done
1922 previously. Hope I haven't missed anything, but it can't do any
1923 harm, as the worst effect is to miss an optimization.
1924
1925 (ii) If, despite (i), such a delivery is accidentally attempted, the
1926 routing retry time is respected, so at least it doesn't keep
1927 hammering the server.

1943 written to the panic log as well as the main log, but it isn't really

48c7f9e2
PH
1948PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1949 runs only) independently of the message's sender address. This meant
1950 that, if the 4xx error was in fact related to the sender, a different
1951 message to the same recipient with a different sender could confuse
1952 things. In particualar, this can happen when sending to a greylisting
1953 server, but other circumstances could also provoke similar problems.
1954 I have changed the default so that the retry time for these errors is now
1955 based a combination of the sender and recipient addresses. This change
1956 can be overridden by setting address_retry_include_sender=false in the

2225PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

2228 tcp-wrappers gives "deny", whereas what one would like would be some
2229 kind of temporary error. A kludge has been added to help with this.
2230 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2231 554 error is used if errno is still zero or contains ENOENT (which occurs
2232 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
2233 451 error is used.

2273 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

2318 autoreply, Exim could try to deliver to a non-existent relative file

2355 major problems that occur when a DNS server includes only records of one

2369PH/19 When calculating a retry time, Exim used to measure the "time since
2370 failure" by looking at the "first failed" field in the retry record. Now
2371 it does not use this if it is later than than the arrival time of the
2372 message. Instead it uses the arrival time. This makes for better
2373 behaviour in cases where some deliveries succeed, thus re-setting the
2374 "first failed" field. An example is a quota failure for a huge message
2375 when small messages continue to be delivered. Without this change, the
2376 "time since failure" will always be short, possible causing more frequent
2377 delivery attempts for the huge message than are intended.

PH
2474PH/42 The content-scanning code uses fopen() to create files in which to put
2475 message data. Previously it was not paying any attention to the mode of
2476 the files. Exim runs with umask(0) because the rest of the code creates
2477 files with open(), and sets the required mode explicitly. Thus, these
2478 files were ending up world-writeable. This was not a big issue, because,
2479 being within the spool directory, they were not world-accessible. I have
2480 created a function called modefopen, which takes an additional mode
2481 argument. It sets umask(777), creates the file, chmods it to the required
2482 mode, then resets the umask. All the relevant calls to fopen() in the
2483 content scanning code have been changed to use this function.

2520
2521 (i) Exim was not creating retry information for temporary errors given
2522 for individual recipients after the DATA command when the smtp transport
2523 was used in LMTP mode. This meant that they could be retried too
2524 frequently, and not timed out correctly.
2525
2526 (ii) Exim was setting the flag that allows error details to be returned
2527 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2528 recipients that were returned after the DATA command.
2529
2530PH/53 This is related to PH/52, but is more general: for any failing address,
2531 when detailed error information was permitted to be returned to the
2532 sender, but the error was temporary, then after the final timeout, only
2533 "retry timeout exceeded" was returned. Now it returns the full error as

2604PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2605 function verify_get_ident() calls ip_connect() to connect a socket, but
2606 if the "connect()" function timed out, ip_connect() used to close the
2607 socket. However, verify_get_ident() also closes the socket later, and in
2608 between Exim writes to the log, which may get opened at this point. When
2609 the socket was closed in ip_connect(), the log could get the same file
2610 descriptor number as the socket. This naturally causes chaos. The fix is
2611 not to close the socket in ip_connect(); the socket should be closed by
2612 the function that creates it. There was only one place in the code where
2613 this was missing, in the iplookup router, which I don't think anybody now
2614 uses, but I've fixed it anyway.

2675
2676 Received: from [1.2.3.4] (helo=[1.2.3.4])

2769PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2770 canonical form (as documented). However, after a host name lookup from
2771 the IP address, check_host() was doing a simple string comparison with
2772 addresses acquired from the DNS when checking that the found name did
2773 have the original IP as one of its addresses. Since any found IPv6
2774 addresses are likely to be in abbreviated form, the comparison could
2775 fail. Luckily, there already exists a function for doing the comparison
2776 by converting both addresses to binary, so now that is used instead of
2777 the text comparison.

PH
2779PH/20 There was another similar case to PH/19, when a complete host name was

2782 The same fix has been applied.

3159PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3160 the configuration file to be ":syslog", then the script "guesses" where
3161 the logs files are, rather than using the compiled in default. In our
3162 case the guess is not the same as the compiled default, so the script
3163 suddenly stopped working when I started to use syslog. The patch checks
3164 to see if log_file_path is "". If so, it attempts to read it from exim
3165 with no configuration file to get the compiled in version, before it
3166 falls back to the previous guessing code."

3222PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3223 specify a transport. However, if an address that was verified by such a
3224 router was the subject of a callout, Exim crashed because it tried to
3225 read the rcpt_include_affixes from the non-existent transport. Now it
3226 just assumes that the setting of that option is false. This bug was
3227 introduced by 4.51/PH/31.

3237PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3238 aren't the modern standard, and it seems that some systems' include files
3239 don't always have them. Exim was already checking for some of the newer
3240 ones like T_AAAA, and defining it itself. I've added checks for all the
3241 record types that Exim uses.

3243PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was

3246 data, a new version was generated, as expected. It was only the case of a
3247 non-existent file that was broken.

3260 message was deferred as in a normal delivery, and thus remained on the
3261 spool, instead of being failed because of the mua_wrapper setting. This
3262 is now fixed, and I tidied up some of the mua_wrapper messages at the
3263 same time.

3294
3295PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3296 that changes the way the GnuTLS parameters are stored in the cache file.
3297 The new format can be generated externally. For backward compatibility,
3298 if the data in the cache doesn't make sense, Exim assumes it has read an
3299 old-format file, and it generates new data and writes a new file. This
3300 means that you can't go back to an older release without removing the
3301 file.
3302
3303PH/03 A redirect router that has both "unseen" and "one_time" set does not
3304 work if there are any delivery delays because "one_time" forces the
3305 parent to be marked "delivered", so its unseen clone is never tried
3306 again. For this reason, Exim now forbids the simultaneous setting of
3307 these two options.
3308
3309PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3310 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3311 entry if you want to know the details. The fix, however, neglected to
3312 consider the case when local delivery batching is involved. The test for
3313 "previously delivered" was not happening when checking to see if an
3314 address could be batched with a previous (undelivered) one; under
3315 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3316 address.

PH
3317
3318PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3320
3321PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3322 header_syntax) but Exim was just ignoring anything given after a slash.
3323 In particular, this caused confusion with an attempt to use "verify =
3324 reverse_host_lookup/defer_ok". An error is now given when options are
3325 supplied for verify items that do not have them. (Maybe reverse_host_
3326 lookup should have a defer_ok option, but that's a different point.)
3327
3328PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3329 defined by RFC 821) to 2048, because there were problems with some AUTH

3331 SMTP commands that take arguments.
