99TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
100
101 When a queue runner is handling a message, Exim first routes the
102 recipient addresses, during which it prunes them based on the retry
103 hints database. After that it attempts to deliver the message to
104 any remaining recipients. It then updates the hints database using
105 the retry rules.
106
107 So if a recipient address works intermittently, it can get repeatedly
108 deferred at routing time. The retry hints record remains fresh so the
109 address never reaches the final cutoff time.
110
111 This is a fairly common occurrence when a user is bumping up against
112 their storage quota. Exim had some logic in its local delivery code
113 to deal with this. However it did not apply to per-recipient defers
114 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
115
1ddeb334
TF
116 This change adds a proper retry rule check during routing so that the
117 final cutoff time is checked against the message's age. We only do
118 this check if there is an address retry record and there is not a
119 domain retry record; this implies that previous attempts to handle
120 the address had the retry_use_local_parts option turned on. We use
121 this as an approximation for the destination being like a local
122 delivery, as in LMTP.
67bd1ab3
TF
123
124 I suspect this new check makes the old local delivery cutoff check
125 redundant, but I have not verified this so I left the code in place.
126

TF
127TF/02 Correct gecos expansion when From: is a prefix of the username.
128
129 Test 0254 submits a message to Exim with the header
130
131 Resent-From: f
132
133 When I ran the test suite under the user fanf2, Exim expanded
134 the header to contain my full name, whereas it should have added
135 a Resent-Sender: header. It erroneously treats any prefix of the
136 username as equal to the username.
137
138 This change corrects that bug.

159JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
160 Server implementation by Todd Lyons, client by JH.
161 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
162 config variable "prdr_enable" controls whether the server
163 advertises the facility. If the client requests PRDR a new
164 acl_data_smtp_prdr ACL is called once for each recipient, after
165 the body content is received and before the acl_smtp_data ACL.
166 The client is controlled by bolth of: a hosts_try_prdr option
167 on the smtp transport, and the server advertisement.
168 Default client logging of deliveries and rejections involving
169 PRDR are flagged with the string "PRDR".

TF
362TF/03 Make the exiwhat support code safe for signals. Previously Exim might
363 lock up or crash if it happened to be inside a call to libc when it
364 got a SIGUSR1 from exiwhat.
365
366 The SIGUSR1 handler appends the current process status to the process
367 log which is later printed by exiwhat. It used to use the general
368 purpose logging code to do this, but several functions it calls are
369 not safe for signals.
370
371 The new output code in the SIGUSR1 handler is specific to the process
372 log, and simple enough that it's easy to inspect for signal safety.
373 Removing some special cases also simplifies the general logging code.
374 Removing the spurious timestamps from the process log simplifies
375 exiwhat.
376

TF
377TF/04 Improved ratelimit ACL condition.
378
379 The /noupdate option has been deprecated in favour of /readonly which
380 has clearer semantics. The /leaky, /strict, and /readonly update modes
381 are mutually exclusive. The update mode is no longer included in the
382 database key; it just determines when the database is updated. (This
383 means that when you upgrde Exim will forget old rate measurements.)
384
385 Exim now checks that the per_* options are used with an update mode that
386 makes sense for the current ACL. For example, when Exim is processing a
387 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
388 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
389 must specify per_mail/readonly. If you omit the update mode it defaults to
390 /leaky where that makes sense (as before) or /readonly where required.
391
392 The /noupdate option is now undocumented but still supported for
393 backwards compatibility. It is equivalent to /readonly except that in
394 ACLs where /readonly is required you may specify /leaky/noupdate or
395 /strict/noupdate which are treated the same as /readonly.
396
397 A useful new feature is the /count= option. This is a generalization
398 of the per_byte option, so that you can measure the throughput of other
399 aggregate values. For example, the per_byte option is now equivalent
400 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
401
402 The per_rcpt option has been generalized using the /count= mechanism
403 (though it's more complicated than the per_byte equivalence). When it is
404 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
405 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
406 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
407 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
408 Note that using per_rcpt with a non-readonly update mode in more than
409 one ACL will cause the recipients to be double-counted. (The per_mail
410 and per_byte options don't have this problem.)
411
412 The handling of very low rates has changed slightly. If the computed rate
413 is less than the event's count (usually one) then this event is the first
414 after a long gap. In this case the rate is set to the same as this event's
415 count, so that the first message of a spam run is counted properly.
416
417 The major new feature is a mechanism for counting the rate of unique
418 events. The new per_addr option counts the number of different
419 recipients that someone has sent messages to in the last time period. It
420 behaves like per_rcpt if all the recipient addresses are different, but
421 duplicate recipient addresses do not increase the measured rate. Like
422 the /count= option this is a general mechanism, so the per_addr option
423 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
424 example, measure the rate that a client uses different sender addresses
425 with the options per_mail/unique=$sender_address. There are further
426 details in the main documentation.

PH
1000PH/02 When an IPv6 address is converted to a string for single-key lookup
1001 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1002 dots are used instead of colons so that keys in lsearch files need not
1003 contain colons. This was done some time before quoting was made available
1004 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1005 (notated using the quote facility) so as to distinguish them from IPv4
1006 keys. This meant that lookups for IP addresses in host lists did not work
1007 for iplsearch lookups.
1008
1009 This has been fixed by arranging for IPv6 addresses to be expressed with
1010 colons if the lookup type is iplsearch. This is not incompatible, because
1011 previously such lookups could never work.
1012
1013 The situation is now rather anomolous, since one *can* have colons in
1014 ordinary lsearch keys. However, making the change in all cases is
1015 incompatible and would probably break a number of configurations.

1020MH/01 The "spam" ACL condition code contained a sscanf() call with a %s

1022 a rogue spamd server to cause a buffer overflow. While nobody in their
1023 right mind would setup Exim to query an untrusted spamd server, an
1024 attacker that gains access to a server running spamd could potentially
1025 exploit this vulnerability to run arbitrary code as the Exim user.

1030MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1031 a directory entry by the name of the lookup key. Previously, if a
1032 symlink pointed to a non-existing file or a file in a directory that
1033 Exim lacked permissions to read, a lookup for a key matching that
1034 symlink would fail. Now it is enough that a matching directory entry

1218PH/29 SMTP synchronization checks are implemented when a command is read -
1219 there is a check that no more input is waiting when there shouldn't be
1220 any. However, for some commands, a delay in an ACL can mean that it is
1221 some time before the response is written. In this time, more input might
1222 arrive, invalidly. So now there are extra checks after an ACL has run for
1223 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1224 pipelining has not been advertised.

1239 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1240 was a macro that became an assignment, so it seemed to work. This has

1298 the response to the final '.' that terminates a message, but only in the
1299 case where the client has not sent further data following the '.'
1300 (unfortunately, this is allowed). However, in many cases there won't be
1301 any further data because there won't be any more messages to send. A call
1302 to select() can be used: if it shows that the input is "ready", there is
1303 either input waiting, or the socket has been closed. An attempt to read
1304 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1305 would have sent an OK response which the client would never have see.

1315
1316PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1317 fixed by 4.65/MH/01 (is this a record?) are fixed:
1318
1319 (i) An empty string was always treated as zero by the numeric comparison
1320 operators. This behaviour has been restored.
1321
1322 (ii) It is documented that the numeric comparison operators always treat
1323 their arguments as decimal numbers. This was broken in that numbers
1324 starting with 0 were being interpreted as octal.
1325
1326 While fixing these problems I realized that there was another issue that
1327 hadn't been noticed. Values of message_size_limit (both the global option
1328 and the transport option) were treated as octal if they started with 0.
1329 The documentation was vague. These values are now always treated as
1330 decimal, and I will make that clear in the documentation.

1346 is held in a short int, deliveries were likely to be lost. As such a
1347 large number of recipients for a single message is ridiculous
1348 (performance will be very, very poor), I have chosen to impose a limit
1349 rather than extend the field.

PH
1374PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1375 callout verification, Exim cached a "reject" for the entire domain. This
1376 is correct for most verifications, but it is not correct for a recipient
1377 verification with use_sender or use_postmaster set, because in that case
1378 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1379 case of MAIL FROM:<> rejection from other early rejections (e.g.
1380 rejection of HELO). When verifying a recipient using a non-null MAIL
1381 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1382 Whatever the result of the callout, the value of the domain cache is
1383 left unchanged (for any other kind of callout, getting as far as trying
1384 RCPT means that the domain itself is ok).

1418PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1420 probably the interface on which it is arriving) and not to the outgoing
1421 callout (which could be using a different interface). This has been
1422 changed to use the value of the helo_data option from the smtp transport
1423 instead - this is what is used when a message is actually being sent. If
1424 there is no remote transport (possible with a router that sets up host
1425 addresses), $smtp_active_hostname is used.

7befa435 1428 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1429 (a) The code assumed that strncpy() returns a negative number on buffer
1430 overflow, which isn't the case. Replaced with Exim's string_format()
1431 function.
1432 (b) There were several signed/unsigned issues. I just did the minimum
1433 hacking in of casts. There is scope for a larger refactoring.
1434 (c) The code used strcasecmp() which is not a standard C function.
1435 Replaced with Exim's strcmpic() function.
1436 (d) The code set only $1; it now sets $auth1 as well.
1437 (e) A simple test gave the error "authentication client didn't specify
1438 service in request". It would seem that Dovecot has changed its
1439 interface. Fortunately there's a specification; I followed it and
1440 changed what the client sends and it appears to be working now.

1446 address A is aliased to B and C, where B exists and C does not. Without
1447 -v the output is "A verified" because verification stops after a
1448 successful redirection if more than one address is generated. However,
1449 with -v the child addresses are also verified. Exim was outputting "A
1450 failed to verify" and then showing the successful verification for C,
1451 with its parentage. It now outputs "B failed to verify", showing B's
1452 parentage before showing the successful verification of C.

322050c2
PH
1458PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1459 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1460 they consult the DNS. I had assumed they would set it the way they
1461 wanted; and indeed my experiments on Linux seem to show that in some
1462 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1463 To be on the safe side, however, I have now made the interface to
1464 host_find_byname() similar to host_find_bydns(), with an argument
1465 containing the DNS resolver options. The host_find_byname() function now
1466 sets these options at its start, just as host_find_bydns() does. The smtp
1467 transport options dns_qualify_single and dns_search_parents are passed to
1468 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1469 of host_find_byname() use the default settings of RES_DEFNAMES
1470 (qualify_single) but not RES_DNSRCH (search_parents).

1473 spool_read_header() do less string testing, by means of a preliminary
1474 switch on the second character of optional "-foo" lines. (This is
1475 overdue, caused by the large number of possibilities that now exist.
1476 Originally there were few.) While I was there, I also converted the
1477 str(n)cmp tests so they don't re-test the leading "-" and the first
1478 character, in the hope this might squeeze out yet more improvement.

PH
1480PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1481 flag allowing group syntax was set by the header_syntax check but not
1482 turned off, possible causing trouble later; (2) The flag was not being
1483 set at all for the header_verify test, causing "group"-style headers to
1484 be rejected. I have now set it in this case, and also caused header_
1485 verify to ignore an empty address taken from a group. While doing this, I
1486 came across some other cases where the code for allowing group syntax
1487 while scanning a header line wasn't quite right (mostly, not resetting
1488 the flag correctly in the right place). These bugs could have caused
1489 trouble for malformed header lines. I hope it is now all correct.

PH
1491PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1494 but it didn't always do it. This confused somebody who was copying the
1495 code for some other use. I have removed all the tests.

PH
1497PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1498 feature that was used to support insecure browsers during the U.S. crypto
1499 embargo. It requires special client support, and Exim is probably the
1500 only MTA that supported it -- and would never use it because real RSA is
1501 always available. This code has been removed, because it had the bad
1502 effect of slowing Exim down by computing (never used) parameters for the
1503 RSA_EXPORT functionality.

1508 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1509 if the connection is using TLS or if the remote IP is the same as the
1510 local IP, and the "valid-client-cert option" if a client certificate has
1511 been verified.

PH
1542
1543PH/30 Exim was sometimes attempting to deliver messages that had suffered
1544 address errors (4xx response to RCPT) over the same connection as other
1545 messages routed to the same hosts. Such deliveries are always "forced",
1546 so retry times are not inspected. This resulted in far too many retries
1547 for the affected addresses. The effect occurred only when there were more
1548 hosts than the hosts_max_try setting in the smtp transport when it had
1549 the 4xx errors. Those hosts that it had tried were not added to the list
1550 of hosts for which the message was waiting, so if all were tried, there
1551 was no problem. Two fixes have been applied:
1552
1553 (i) If there are any address or message errors in an SMTP delivery, none
1554 of the hosts (tried or untried) are now added to the list of hosts
1555 for which the message is waiting, so the message should not be a
1556 candidate for sending over the same connection that was used for a
1557 successful delivery of some other message. This seems entirely
1558 reasonable: after all the message is NOT "waiting for some host".
1559 This is so "obvious" that I'm not sure why it wasn't done
1560 previously. Hope I haven't missed anything, but it can't do any
1561 harm, as the worst effect is to miss an optimization.
1562
1563 (ii) If, despite (i), such a delivery is accidentally attempted, the
1564 routing retry time is respected, so at least it doesn't keep
1565 hammering the server.

1580PH/35 The error "getsockname() failed: connection reset by peer" was being
1581 written to the panic log as well as the main log, but it isn't really
1582 panic-worthy as it just means the connection died rather early on. I have
1583 removed the panic log writing for the ECONNRESET error when getsockname()
1584 fails.

1586PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1587 runs only) independently of the message's sender address. This meant
1588 that, if the 4xx error was in fact related to the sender, a different
1589 message to the same recipient with a different sender could confuse
1590 things. In particualar, this can happen when sending to a greylisting
1591 server, but other circumstances could also provoke similar problems.
1592 I have changed the default so that the retry time for these errors is now
1593 based a combination of the sender and recipient addresses. This change
1594 can be overridden by setting address_retry_include_sender=false in the
1595 smtp transport.

1866 tcp-wrappers gives "deny", whereas what one would like would be some
1867 kind of temporary error. A kludge has been added to help with this.
1868 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1869 554 error is used if errno is still zero or contains ENOENT (which occurs
1870 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1973PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
1974 used if the router is not running as root, for example, when verifying at
1975 ACL time, or when using -bh. The debugging output from this situation was
1976 non-existent - all you got was a failure to exec. I have made two
1977 changes:
1978
1979 (a) Failures to set uid/gid, the current directory, or a process leader
1980 in a subprocess such as that created by queryprogram now generate
1981 suitable debugging ouput when -d is set.
1982
1983 (b) The queryprogram router detects when it is not running as root,
1984 outputs suitable debugging information if -d is set, and then runs
1985 the subprocess without attempting to change uid/gid.

1990PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1991 additional section of a DNS packet that returns MX or SRV records.
1992 Instead, it always explicitly searches for A/AAAA records. This avoids
1993 major problems that occur when a DNS server includes only records of one
1994 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1995 fixed another bug: if SRV records were looked up and the corresponding
1996 address records were *not* found in the additional section, the port
1997 values from the SRV records were lost.

2007PH/19 When calculating a retry time, Exim used to measure the "time since
2008 failure" by looking at the "first failed" field in the retry record. Now
2009 it does not use this if it is later than than the arrival time of the
2010 message. Instead it uses the arrival time. This makes for better
2011 behaviour in cases where some deliveries succeed, thus re-setting the
2012 "first failed" field. An example is a quota failure for a huge message
2013 when small messages continue to be delivered. Without this change, the
2014 "time since failure" will always be short, possible causing more frequent
2015 delivery attempts for the huge message than are intended.

PH
2112PH/42 The content-scanning code uses fopen() to create files in which to put
2113 message data. Previously it was not paying any attention to the mode of
2114 the files. Exim runs with umask(0) because the rest of the code creates
2115 files with open(), and sets the required mode explicitly. Thus, these
2116 files were ending up world-writeable. This was not a big issue, because,
2117 being within the spool directory, they were not world-accessible. I have
2118 created a function called modefopen, which takes an additional mode
2119 argument. It sets umask(777), creates the file, chmods it to the required
2120 mode, then resets the umask. All the relevant calls to fopen() in the
2121 content scanning code have been changed to use this function.

2133 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2134 they are received. Thus, the responses can be made to depend on the

2156PH/52 Two bugs concerned with error handling when the smtp transport is
2157 used in LMTP mode:
2158
2159 (i) Exim was not creating retry information for temporary errors given
2160 for individual recipients after the DATA command when the smtp transport
2161 was used in LMTP mode. This meant that they could be retried too
2162 frequently, and not timed out correctly.
2163
2164 (ii) Exim was setting the flag that allows error details to be returned
2165 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2166 recipients that were returned after the DATA command.
2167
2168PH/53 This is related to PH/52, but is more general: for any failing address,
2169 when detailed error information was permitted to be returned to the
2170 sender, but the error was temporary, then after the final timeout, only
2171 "retry timeout exceeded" was returned. Now it returns the full error as

2242PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2243 function verify_get_ident() calls ip_connect() to connect a socket, but
2244 if the "connect()" function timed out, ip_connect() used to close the
2245 socket. However, verify_get_ident() also closes the socket later, and in
2246 between Exim writes to the log, which may get opened at this point. When
2247 the socket was closed in ip_connect(), the log could get the same file
2248 descriptor number as the socket. This naturally causes chaos. The fix is
2249 not to close the socket in ip_connect(); the socket should be closed by
2250 the function that creates it. There was only one place in the code where
2251 this was missing, in the iplookup router, which I don't think anybody now
2252 uses, but I've fixed it anyway.

2312 identical. For example:
2313
2314 Received: from [1.2.3.4] (helo=[1.2.3.4])
2315
2316 However, if the real host name was known, it was omitting the HELO data

2407PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2408 canonical form (as documented). However, after a host name lookup from
2409 the IP address, check_host() was doing a simple string comparison with
2410 addresses acquired from the DNS when checking that the found name did
2411 have the original IP as one of its addresses. Since any found IPv6
2412 addresses are likely to be in abbreviated form, the comparison could
2413 fail. Luckily, there already exists a function for doing the comparison
2414 by converting both addresses to binary, so now that is used instead of
2415 the text comparison.
2416

PH
2417PH/20 There was another similar case to PH/19, when a complete host name was

2420 The same fix has been applied.

2799 the logs files are, rather than using the compiled in default. In our
2800 case the guess is not the same as the compiled default, so the script
2801 suddenly stopped working when I started to use syslog. The patch checks
2802 to see if log_file_path is "". If so, it attempts to read it from exim
2803 with no configuration file to get the compiled in version, before it
2804 falls back to the previous guessing code."

2863 read the rcpt_include_affixes from the non-existent transport. Now it

2932
2933PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2934 that changes the way the GnuTLS parameters are stored in the cache file.
2935 The new format can be generated externally. For backward compatibility,
2936 if the data in the cache doesn't make sense, Exim assumes it has read an
2937 old-format file, and it generates new data and writes a new file. This
2938 means that you can't go back to an older release without removing the
2939 file.
2940
2941PH/03 A redirect router that has both "unseen" and "one_time" set does not
2942 work if there are any delivery delays because "one_time" forces the
2943 parent to be marked "delivered", so its unseen clone is never tried
2944 again. For this reason, Exim now forbids the simultaneous setting of
2945 these two options.
2946
2947PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2948 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2949 entry if you want to know the details. The fix, however, neglected to
2950 consider the case when local delivery batching is involved. The test for
2951 "previously delivered" was not happening when checking to see if an
2952 address could be batched with a previous (undelivered) one; under
2953 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2954 address.

2956PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2959PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2960 header_syntax) but Exim was just ignoring anything given after a slash.
2961 In particular, this caused confusion with an attempt to use "verify =
2962 reverse_host_lookup/defer_ok". An error is now given when options are
2963 supplied for verify items that do not have them. (Maybe reverse_host_
2964 lookup should have a defer_ok option, but that's a different point.)
2965
2966PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3016PH/19 When an Exim process that is running as root has to create an Exim log
3017 file, it does so in a subprocess that runs as exim:exim so as to get the
3018 ownership right at creation (otherwise, other Exim processes might see
3019 the file with the wrong ownership). There was no test for failure of this
3020 fork() call, which would lead to the process getting stuck as it waited
3021 for a non-existent subprocess. Forks do occasionally fail when resources
3022 run out. I reviewed all the other calls to fork(); they all seem to check
3023 for failure.

3028 the result was a log entry for a synchronization error with an empty
3029 string after "input=" when read() returned zero. If read() returned -1

c5ddb310
PH
3042PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3043 hadn't been configured. The fix is from Juergen Kreileder, who
3044 understands it better than I do:
3045
3046 "Here's what I see happening with three configured cyrus_sasl
3047 authenticators configured (plain, login, cram-md5):
3048
3049 On startup auth_cyrus_sasl_init() gets called for each of these.
3050 This means three calls to sasl_listmech() without a specified mech_list.
3051 => SASL tests which mechs of all available mechs actually work
3052 => three warnings about OTP not working
3053 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3054
3055 With the patch, sasl_listmech() also gets called three times. But now
3056 SASL's mech_list option is set to the server_mech specified in the the
3057 authenticator. Or in other words, the answer from sasl_listmech()
3058 gets limited to just the mech you're testing for (which is different
3059 for each call.)
3060 => the return list contains just 'plain' or 'login', 'cram-md5' or
3061 nothing depending on the value of ob->server_mech.
3062
3063 I've just tested the patch: Authentication still works fine,
3064 unavailable mechs specified in the exim configuration are still
3065 caught, and the auth.log warnings about OTP are gone."

PH
3129PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3130 the grounds that routing the same address twice would always produce the
3131 same answer. This might have been true once, but it is certainly no
3132 longer true now. Routing a child address may depend on the previous
3133 routing that produced that child. Some complicated redirection strategies
3134 went wrong when messages had multiple recipients, and made Exim's
3135 behaviour dependent on the order in which the addresses were given.
3136
3137 I have moved the duplicate checking until after the routing is complete.
3138 Exim scans the addresses that are assigned to local and remote
3139 transports, and removes any duplicates. This means that more work will be
3140 done, as duplicates will always all be routed, but duplicates are
3141 presumably rare, so I don't expect this is of any significance.
3142
3143 For deliveries to pipes, files, and autoreplies, the duplicate checking
3144 still happens during the routing process, since they are not going to be
3145 routed further.

3172 (c) A message specified in a "fail" command in a system filter;
3173 (d) A message specified in a FAIL return from the queryprogram router;
3174 (e) A message specified by the cannot_route_message router option.
3175
3176 In these cases only, Exim does include the error details in bounce and
3177 warning messages. There are also a few cases where bland messages such
3178 as "unrouteable address" or "local delivery error" are given.

3186PH/45 In a pipe transport, although a timeout while waiting for the pipe
3187 process to complete was treated as a delivery failure, a timeout while
3188 writing the message to the pipe was logged, but erroneously treated as a
3189 successful delivery. Such timeouts include transport filter timeouts. For
3190 consistency with the overall process timeout, these timeouts are now
3191 treated as errors, giving rise to delivery failures by default. However,
3192 there is now a new Boolean option for the pipe transport called
3193 timeout_defer, which, if set TRUE, converts the failures into defers for
3194 both kinds of timeout. A transport filter timeout is now identified in
3195 the log output.

3197PH/46 The "scripts/Configure-config.h" script calls "make" at one point. On

3200 from the Makefile to this script so that it can call the same version of
3201 "make".

3204A note about Exim versions 4.44 and 4.50
3205----------------------------------------
3206
3207Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3208changes of various kinds. As a consequence, a big documentation update was
3209needed. This delayed the release for rather longer than seemed good, especially
3210in the light of a couple of (minor) security issues. Therefore, the changes
3211that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3212release. So 4.44 and 4.50 are in effect two different branches that both start
3213from 4.43.
3214
3215I have left the 4.50 change log unchanged; it contains all the changes since
32164.43. The change log for 4.44 is below; many of its items are identical to
3217those for 4.50. This seems to be the most sensible way to preserve the
3218historical information.

3224 1. Minor wording change to the doc/README.SIEVE file.
3225
139059f6 3226 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 3227 computation of the current number of files was incorrect.

3229 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3230 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3231 place.
3232

3233 4. Give more explanation in the error message when the command for a transport
3234 filter fails to execute.

PH
3236 5. There are several places where Exim runs a non-Exim command in a
3237 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3238 was being done only for the command run by the queryprogram router. It is
3239 now done for all such subprocesses. The other cases are: ${run, transport
3240 filters, and the commands run by the lmtp and pipe transports.

3242 6. Added CONFIGURE_GROUP build-time option.
3243
3244 7. Some older OS have a limit of 256 on the maximum number of file
3245 descriptors. Exim was using setrlimit() to set 1000 as a large value
3246 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3247 systems. I've change it so that if it can't get 1000, it tries for 256.

3249 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3250 was an oversight, and furthermore, ever since the addition of extra
3251 controls (e.g. 4.43/32), the checks on when to allow different forms of
3252 "control" were broken. There should now be diagnostics for all cases when a
3253 control that does not make sense is encountered.

325911. Tidy the search cache before the fork to do a delivery from a message
3260 received from the command line. Otherwise the child will trigger a lookup
3261 failure and thereby defer the delivery if it tries to use (for example) a
3262 cached ldap connection that the parent has called unbind on.

326412. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3265 of $address_data from the recipient verification was clobbered by the
3266 sender verification.
3267
326813. The value of address_data from a sender verification is now available in
3269 $sender_address_data in subsequent conditions in the ACL statement.

327616. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3277 was its contents. (It was OK if the option was not defined at all.)

328720. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3288 handles timeouts, both on the server side and network timeouts. Renamed the
3289 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).

329422. $host_address is now set to the target address during the checking of
3295 ignore_target_hosts.
3296
329723. When checking ignore_target_hosts for an ipliteral router, no host name was
3298 being passed; this would have caused $sender_host_name to have been used if
3299 matching the list had actually called for a host name (not very likely,
3300 since this list is usually IP addresses). A host name is now passed as
3301 "[x.x.x.x]".
3302
7d468ab8
PH
330324. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3304 code that specifies a non-restarting handler (typically sigaction() in
3305 modern systems) in an attempt to fix a rare and obscure crash bug.
3306
330725. Narrowed the window for a race in the daemon that could cause it to ignore
3308 SIGCHLD signals. This is not a major problem, because they are used only to
3309 wake it up if nothing else does.
3310

PH
331126. A malformed maildirsize file could cause Exim to calculate negative values
3312 for the mailbox size or file count. Odd effects could occur as a result.
3313 The maildirsize information is now recalculated if the size or filecount
3314 end up negative.
3315

PH
332129. In an address list, if the pattern was not a regular expression, an empty
3322 subject address (from a bounce message) matched only if the pattern was an
3323 empty string. Non-empty patterns were not even tested. This was the wrong
3324 because it is perfectly reasonable to use an empty address as part of a
3325 database query. An empty address is now tested by patterns that are
3326 lookups. However, all the other forms of pattern expect the subject to
3327 contain a local part and a domain, and therefore, for them, an empty
3328 address still always fails if the pattern is not itself empty.

333030. Exim went into a mad DNS loop when attempting to do a callout where the
3331 host was specified on an smtp transport, and looking it up yielded more
3332 than one IP address.
3333

PH
333431. Re-factored the code for checking spool and log partition space into a
3335 function that finds that data and another that does the check. The former
3336 is then used to implement four new variables: $spool_space, $log_space,
3337 $spool_inodes, and $log_inodes.
3338

PH
333932. The RFC2047 encoding function was originally intended for short strings
3340 such as real names; it was not keeping to the 75-character limit for
3341 encoded words that the RFC imposes. It now respects the limit, and
3342 generates multiple encoded words if necessary. To be on the safe side, I
3343 have increased the buffer size for the ${rfc2047: expansion operator from
3344 1024 to 2048 bytes.
3345
063b1e99
PH
334633. It is now permitted to omit both strings after an "if" condition; if the
3347 condition is true, the result is "true". As before, when the second string
3348 is omitted, a false condition yields an empty string. This makes it less
3349 cumbersome to write custom ACL and router conditions.
3350
652e1b65
PH
335134. Failure to deliver a bounce message always caused it to be frozen, even if
3352 there was an errors_to setting on the router. The errors_to setting is now
3353 respected.
3354
6f0c9a4f
PH
335535. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3356 canonical form (fully expanded) before being placed in
3357 $sender_host_address.
3358
33397d19
PH
335936. The table in the code that translates DNS record types into text (T_A to
3360 "A" for instance) was missing entries for NS and CNAME. It is just possible
3361 that this could have caused confusion if both these types were looked up
3362 for the same domain, because the text type is used as part of Exim's
3363 per-process caching. But the chance of anyone hitting this buglet seems
3364 very small.
3365
7bb56e1f
PH
336637. The dnsdb lookup has been extended in a number of ways.
3367
3368 (1) There is a new type, "zns", which walks up the domain tree until it
3369 finds some nameserver records. It should be used with care.
3370

PH
3371 (2) There is a new type, "mxh", which is like "mx" except that it returns
3372 just the host names, not the priorities.
3373
3374 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3375 looked up. The behaviour when one of the lookups defers can be
3376 controlled by a keyword.
7bb56e1f 3377
ea3bc19b 3378 (4) It is now possible to specify the separator character for use when
7bb56e1f 3379 multiple records are returned.

338138. The dnslists ACL condition has been extended: it is now possible to supply
3382 a list of IP addresses and/or domains to be looked up in a particular DNS
3383 domain.
