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
326cdc37
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".

179 This is now consistent with GnuTLS, and is now documented: the
180 previous undocumented portable approach to treating the option as
181 unset was to force an expansion failure. That still works, and
182 an empty string is now equivalent.

TF
372TF/03 Make the exiwhat support code safe for signals. Previously Exim might
373 lock up or crash if it happened to be inside a call to libc when it
374 got a SIGUSR1 from exiwhat.
375
376 The SIGUSR1 handler appends the current process status to the process
377 log which is later printed by exiwhat. It used to use the general
378 purpose logging code to do this, but several functions it calls are
379 not safe for signals.
380
381 The new output code in the SIGUSR1 handler is specific to the process
382 log, and simple enough that it's easy to inspect for signal safety.
383 Removing some special cases also simplifies the general logging code.
384 Removing the spurious timestamps from the process log simplifies
385 exiwhat.
386
c99ce5c9
TF
387TF/04 Improved ratelimit ACL condition.
388
389 The /noupdate option has been deprecated in favour of /readonly which
390 has clearer semantics. The /leaky, /strict, and /readonly update modes
391 are mutually exclusive. The update mode is no longer included in the
392 database key; it just determines when the database is updated. (This
393 means that when you upgrde Exim will forget old rate measurements.)
394
395 Exim now checks that the per_* options are used with an update mode that
396 makes sense for the current ACL. For example, when Exim is processing a
397 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
398 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
399 must specify per_mail/readonly. If you omit the update mode it defaults to
400 /leaky where that makes sense (as before) or /readonly where required.
401
402 The /noupdate option is now undocumented but still supported for
403 backwards compatibility. It is equivalent to /readonly except that in
404 ACLs where /readonly is required you may specify /leaky/noupdate or
405 /strict/noupdate which are treated the same as /readonly.
406
407 A useful new feature is the /count= option. This is a generalization
408 of the per_byte option, so that you can measure the throughput of other
409 aggregate values. For example, the per_byte option is now equivalent
410 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
411
412 The per_rcpt option has been generalized using the /count= mechanism
413 (though it's more complicated than the per_byte equivalence). When it is
414 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
415 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
416 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
417 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
418 Note that using per_rcpt with a non-readonly update mode in more than
419 one ACL will cause the recipients to be double-counted. (The per_mail
420 and per_byte options don't have this problem.)
421
422 The handling of very low rates has changed slightly. If the computed rate
423 is less than the event's count (usually one) then this event is the first
424 after a long gap. In this case the rate is set to the same as this event's
425 count, so that the first message of a spam run is counted properly.
426
427 The major new feature is a mechanism for counting the rate of unique
428 events. The new per_addr option counts the number of different
429 recipients that someone has sent messages to in the last time period. It
430 behaves like per_rcpt if all the recipient addresses are different, but
431 duplicate recipient addresses do not increase the measured rate. Like
432 the /count= option this is a general mechanism, so the per_addr option
433 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
434 example, measure the rate that a client uses different sender addresses
435 with the options per_mail/unique=$sender_address. There are further
436 details in the main documentation.

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

1008PH/01 Another patch from the Sieve maintainer.
1009
6a3bceb1
PH
1010PH/02 When an IPv6 address is converted to a string for single-key lookup
1011 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1012 dots are used instead of colons so that keys in lsearch files need not
1013 contain colons. This was done some time before quoting was made available
1014 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1015 (notated using the quote facility) so as to distinguish them from IPv4
1016 keys. This meant that lookups for IP addresses in host lists did not work
1017 for iplsearch lookups.
1018
1019 This has been fixed by arranging for IPv6 addresses to be expressed with
1020 colons if the lookup type is iplsearch. This is not incompatible, because
1021 previously such lookups could never work.
1022
1023 The situation is now rather anomolous, since one *can* have colons in
1024 ordinary lsearch keys. However, making the change in all cases is
1025 incompatible and would probably break a number of configurations.

1030MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1031 conversion specification without a maximum field width, thereby enabling
1032 a rogue spamd server to cause a buffer overflow. While nobody in their
1033 right mind would setup Exim to query an untrusted spamd server, an
1034 attacker that gains access to a server running spamd could potentially
1035 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1040MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1041 a directory entry by the name of the lookup key. Previously, if a
1042 symlink pointed to a non-existing file or a file in a directory that
1043 Exim lacked permissions to read, a lookup for a key matching that
1044 symlink would fail. Now it is enough that a matching directory entry
1045 exists, symlink or not. (Bugzilla 503.)

1228PH/29 SMTP synchronization checks are implemented when a command is read -
1229 there is a check that no more input is waiting when there shouldn't be
1230 any. However, for some commands, a delay in an ACL can mean that it is
1231 some time before the response is written. In this time, more input might
1232 arrive, invalidly. So now there are extra checks after an ACL has run for
1233 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1234 pipelining has not been advertised.

1249 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1250 was a macro that became an assignment, so it seemed to work. This has

1290 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1308 the response to the final '.' that terminates a message, but only in the
1309 case where the client has not sent further data following the '.'
1310 (unfortunately, this is allowed). However, in many cases there won't be
1311 any further data because there won't be any more messages to send. A call
1312 to select() can be used: if it shows that the input is "ready", there is
1313 either input waiting, or the socket has been closed. An attempt to read
1314 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1315 would have sent an OK response which the client would never have see.

1325
1326PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1327 fixed by 4.65/MH/01 (is this a record?) are fixed:
1328
1329 (i) An empty string was always treated as zero by the numeric comparison
1330 operators. This behaviour has been restored.
1331
1332 (ii) It is documented that the numeric comparison operators always treat
1333 their arguments as decimal numbers. This was broken in that numbers
1334 starting with 0 were being interpreted as octal.
1335
1336 While fixing these problems I realized that there was another issue that
1337 hadn't been noticed. Values of message_size_limit (both the global option
1338 and the transport option) were treated as octal if they started with 0.
1339 The documentation was vague. These values are now always treated as
1340 decimal, and I will make that clear in the documentation.

1355 child addresses, Exim now panics and dies. Previously, because the count
1356 is held in a short int, deliveries were likely to be lost. As such a
1357 large number of recipients for a single message is ridiculous
1358 (performance will be very, very poor), I have chosen to impose a limit
1359 rather than extend the field.

2b1c6e3a
PH
1384PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1385 callout verification, Exim cached a "reject" for the entire domain. This
1386 is correct for most verifications, but it is not correct for a recipient
1387 verification with use_sender or use_postmaster set, because in that case
1388 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1389 case of MAIL FROM:<> rejection from other early rejections (e.g.
1390 rejection of HELO). When verifying a recipient using a non-null MAIL
1391 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1392 Whatever the result of the callout, the value of the domain cache is
1393 left unchanged (for any other kind of callout, getting as far as trying
1394 RCPT means that the domain itself is ok).

1428PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1429 hostname. This is wrong, because it relates to the incoming message (and
1430 probably the interface on which it is arriving) and not to the outgoing
1431 callout (which could be using a different interface). This has been
1432 changed to use the value of the helo_data option from the smtp transport
1433 instead - this is what is used when a message is actually being sent. If
1434 there is no remote transport (possible with a router that sets up host
1435 addresses), $smtp_active_hostname is used.

7befa435 1438 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1439 (a) The code assumed that strncpy() returns a negative number on buffer
1440 overflow, which isn't the case. Replaced with Exim's string_format()
1441 function.
1442 (b) There were several signed/unsigned issues. I just did the minimum
1443 hacking in of casts. There is scope for a larger refactoring.
1444 (c) The code used strcasecmp() which is not a standard C function.
1445 Replaced with Exim's strcmpic() function.
1446 (d) The code set only $1; it now sets $auth1 as well.
1447 (e) A simple test gave the error "authentication client didn't specify
1448 service in request". It would seem that Dovecot has changed its
1449 interface. Fortunately there's a specification; I followed it and
1450 changed what the client sends and it appears to be working now.

1456 address A is aliased to B and C, where B exists and C does not. Without
1457 -v the output is "A verified" because verification stops after a
1458 successful redirection if more than one address is generated. However,
1459 with -v the child addresses are also verified. Exim was outputting "A
1460 failed to verify" and then showing the successful verification for C,
1461 with its parentage. It now outputs "B failed to verify", showing B's
1462 parentage before showing the successful verification of C.

1467
322050c2
PH
1468PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1469 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1470 they consult the DNS. I had assumed they would set it the way they
1471 wanted; and indeed my experiments on Linux seem to show that in some
1472 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1473 To be on the safe side, however, I have now made the interface to
1474 host_find_byname() similar to host_find_bydns(), with an argument
1475 containing the DNS resolver options. The host_find_byname() function now
1476 sets these options at its start, just as host_find_bydns() does. The smtp
1477 transport options dns_qualify_single and dns_search_parents are passed to
1478 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1479 of host_find_byname() use the default settings of RES_DEFNAMES
1480 (qualify_single) but not RES_DNSRCH (search_parents).

1482PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1483 spool_read_header() do less string testing, by means of a preliminary
1484 switch on the second character of optional "-foo" lines. (This is
1485 overdue, caused by the large number of possibilities that now exist.
1486 Originally there were few.) While I was there, I also converted the
1487 str(n)cmp tests so they don't re-test the leading "-" and the first
1488 character, in the hope this might squeeze out yet more improvement.

PH
1490PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1491 flag allowing group syntax was set by the header_syntax check but not
1492 turned off, possible causing trouble later; (2) The flag was not being
1493 set at all for the header_verify test, causing "group"-style headers to
1494 be rejected. I have now set it in this case, and also caused header_
1495 verify to ignore an empty address taken from a group. While doing this, I
1496 came across some other cases where the code for allowing group syntax
1497 while scanning a header line wasn't quite right (mostly, not resetting
1498 the flag correctly in the right place). These bugs could have caused
1499 trouble for malformed header lines. I hope it is now all correct.

PH
1501PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1502 with the "reply" argument non-NULL. The code, however (which originally
1503 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1504 but it didn't always do it. This confused somebody who was copying the
1505 code for some other use. I have removed all the tests.

PH
1507PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1508 feature that was used to support insecure browsers during the U.S. crypto
1509 embargo. It requires special client support, and Exim is probably the
1510 only MTA that supported it -- and would never use it because real RSA is
1511 always available. This code has been removed, because it had the bad
1512 effect of slowing Exim down by computing (never used) parameters for the
1513 RSA_EXPORT functionality.

1518 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1519 if the connection is using TLS or if the remote IP is the same as the
1520 local IP, and the "valid-client-cert option" if a client certificate has
1521 been verified.

PH
1552
1553PH/30 Exim was sometimes attempting to deliver messages that had suffered
1554 address errors (4xx response to RCPT) over the same connection as other
1555 messages routed to the same hosts. Such deliveries are always "forced",
1556 so retry times are not inspected. This resulted in far too many retries
1557 for the affected addresses. The effect occurred only when there were more
1558 hosts than the hosts_max_try setting in the smtp transport when it had
1559 the 4xx errors. Those hosts that it had tried were not added to the list
1560 of hosts for which the message was waiting, so if all were tried, there
1561 was no problem. Two fixes have been applied:
1562
1563 (i) If there are any address or message errors in an SMTP delivery, none
1564 of the hosts (tried or untried) are now added to the list of hosts
1565 for which the message is waiting, so the message should not be a
1566 candidate for sending over the same connection that was used for a
1567 successful delivery of some other message. This seems entirely
1568 reasonable: after all the message is NOT "waiting for some host".
1569 This is so "obvious" that I'm not sure why it wasn't done
1570 previously. Hope I haven't missed anything, but it can't do any
1571 harm, as the worst effect is to miss an optimization.
1572
1573 (ii) If, despite (i), such a delivery is accidentally attempted, the
1574 routing retry time is respected, so at least it doesn't keep
1575 hammering the server.

1591 written to the panic log as well as the main log, but it isn't really

PH
1596PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1597 runs only) independently of the message's sender address. This meant
1598 that, if the 4xx error was in fact related to the sender, a different
1599 message to the same recipient with a different sender could confuse
1600 things. In particualar, this can happen when sending to a greylisting
1601 server, but other circumstances could also provoke similar problems.
1602 I have changed the default so that the retry time for these errors is now
1603 based a combination of the sender and recipient addresses. This change
1604 can be overridden by setting address_retry_include_sender=false in the
1605 smtp transport.

1876 tcp-wrappers gives "deny", whereas what one would like would be some
1877 kind of temporary error. A kludge has been added to help with this.
1878 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1879 554 error is used if errno is still zero or contains ENOENT (which occurs
1880 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1986 non-existent - all you got was a failure to exec. I have made two
1987 changes:
1988
1989 (a) Failures to set uid/gid, the current directory, or a process leader
1990 in a subprocess such as that created by queryprogram now generate
1991 suitable debugging ouput when -d is set.

1995 the subprocess without attempting to change uid/gid.

2000PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2001 additional section of a DNS packet that returns MX or SRV records.
2002 Instead, it always explicitly searches for A/AAAA records. This avoids
2003 major problems that occur when a DNS server includes only records of one
2004 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2005 fixed another bug: if SRV records were looked up and the corresponding
2006 address records were *not* found in the additional section, the port
2007 values from the SRV records were lost.

2017PH/19 When calculating a retry time, Exim used to measure the "time since
2018 failure" by looking at the "first failed" field in the retry record. Now
2019 it does not use this if it is later than than the arrival time of the
2020 message. Instead it uses the arrival time. This makes for better
2021 behaviour in cases where some deliveries succeed, thus re-setting the
2022 "first failed" field. An example is a quota failure for a huge message
2023 when small messages continue to be delivered. Without this change, the
2024 "time since failure" will always be short, possible causing more frequent
2025 delivery attempts for the huge message than are intended.

PH
2122PH/42 The content-scanning code uses fopen() to create files in which to put
2123 message data. Previously it was not paying any attention to the mode of
2124 the files. Exim runs with umask(0) because the rest of the code creates
2125 files with open(), and sets the required mode explicitly. Thus, these
2126 files were ending up world-writeable. This was not a big issue, because,
2127 being within the spool directory, they were not world-accessible. I have
2128 created a function called modefopen, which takes an additional mode
2129 argument. It sets umask(777), creates the file, chmods it to the required
2130 mode, then resets the umask. All the relevant calls to fopen() in the
2131 content scanning code have been changed to use this function.

2168
2169 (i) Exim was not creating retry information for temporary errors given
2170 for individual recipients after the DATA command when the smtp transport
2171 was used in LMTP mode. This meant that they could be retried too
2172 frequently, and not timed out correctly.
2173
2174 (ii) Exim was setting the flag that allows error details to be returned
2175 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2176 recipients that were returned after the DATA command.
2177
2178PH/53 This is related to PH/52, but is more general: for any failing address,
2179 when detailed error information was permitted to be returned to the
2180 sender, but the error was temporary, then after the final timeout, only
2181 "retry timeout exceeded" was returned. Now it returns the full error as

2252PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2253 function verify_get_ident() calls ip_connect() to connect a socket, but
2254 if the "connect()" function timed out, ip_connect() used to close the
2255 socket. However, verify_get_ident() also closes the socket later, and in
2256 between Exim writes to the log, which may get opened at this point. When
2257 the socket was closed in ip_connect(), the log could get the same file
2258 descriptor number as the socket. This naturally causes chaos. The fix is
2259 not to close the socket in ip_connect(); the socket should be closed by
2260 the function that creates it. There was only one place in the code where
2261 this was missing, in the iplookup router, which I don't think anybody now
2262 uses, but I've fixed it anyway.

2323
2324 Received: from [1.2.3.4] (helo=[1.2.3.4])

2417PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2418 canonical form (as documented). However, after a host name lookup from
2419 the IP address, check_host() was doing a simple string comparison with
2420 addresses acquired from the DNS when checking that the found name did
2421 have the original IP as one of its addresses. Since any found IPv6
2422 addresses are likely to be in abbreviated form, the comparison could
2423 fail. Luckily, there already exists a function for doing the comparison
2424 by converting both addresses to binary, so now that is used instead of
2425 the text comparison.
2426

PH
2427PH/20 There was another similar case to PH/19, when a complete host name was

2809 the logs files are, rather than using the compiled in default. In our
2810 case the guess is not the same as the compiled default, so the script
2811 suddenly stopped working when I started to use syslog. The patch checks
2812 to see if log_file_path is "". If so, it attempts to read it from exim

2814 falls back to the previous guessing code."

2942
2943PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2944 that changes the way the GnuTLS parameters are stored in the cache file.
2945 The new format can be generated externally. For backward compatibility,
2946 if the data in the cache doesn't make sense, Exim assumes it has read an
2947 old-format file, and it generates new data and writes a new file. This
2948 means that you can't go back to an older release without removing the
2949 file.
2950
2951PH/03 A redirect router that has both "unseen" and "one_time" set does not
2952 work if there are any delivery delays because "one_time" forces the
2953 parent to be marked "delivered", so its unseen clone is never tried
2954 again. For this reason, Exim now forbids the simultaneous setting of
2955 these two options.
2956
2957PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2958 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2959 entry if you want to know the details. The fix, however, neglected to
2960 consider the case when local delivery batching is involved. The test for
2961 "previously delivered" was not happening when checking to see if an
2962 address could be batched with a previous (undelivered) one; under
2963 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2964 address.

2969PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2970 header_syntax) but Exim was just ignoring anything given after a slash.
2971 In particular, this caused confusion with an attempt to use "verify =
2972 reverse_host_lookup/defer_ok". An error is now given when options are
2973 supplied for verify items that do not have them. (Maybe reverse_host_
2974 lookup should have a defer_ok option, but that's a different point.)
2975
2976PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3028 ownership right at creation (otherwise, other Exim processes might see
3029 the file with the wrong ownership). There was no test for failure of this
3030 fork() call, which would lead to the process getting stuck as it waited
3031 for a non-existent subprocess. Forks do occasionally fail when resources
3032 run out. I reviewed all the other calls to fork(); they all seem to check

3038 the result was a log entry for a synchronization error with an empty
3039 string after "input=" when read() returned zero. If read() returned -1

PH
3052PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3053 hadn't been configured. The fix is from Juergen Kreileder, who
3054 understands it better than I do:
3055
3056 "Here's what I see happening with three configured cyrus_sasl
3057 authenticators configured (plain, login, cram-md5):
3058
3059 On startup auth_cyrus_sasl_init() gets called for each of these.
3060 This means three calls to sasl_listmech() without a specified mech_list.
3061 => SASL tests which mechs of all available mechs actually work
3062 => three warnings about OTP not working
3063 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3064
3065 With the patch, sasl_listmech() also gets called three times. But now
3066 SASL's mech_list option is set to the server_mech specified in the the
3067 authenticator. Or in other words, the answer from sasl_listmech()
3068 gets limited to just the mech you're testing for (which is different
3069 for each call.)
3070 => the return list contains just 'plain' or 'login', 'cram-md5' or
3071 nothing depending on the value of ob->server_mech.
3072
3073 I've just tested the patch: Authentication still works fine,

PH
3139PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3140 the grounds that routing the same address twice would always produce the
3141 same answer. This might have been true once, but it is certainly no
3142 longer true now. Routing a child address may depend on the previous
3143 routing that produced that child. Some complicated redirection strategies
3144 went wrong when messages had multiple recipients, and made Exim's
3145 behaviour dependent on the order in which the addresses were given.
3146
3147 I have moved the duplicate checking until after the routing is complete.
3148 Exim scans the addresses that are assigned to local and remote
3149 transports, and removes any duplicates. This means that more work will be
3150 done, as duplicates will always all be routed, but duplicates are
3151 presumably rare, so I don't expect this is of any significance.
3152
3153 For deliveries to pipes, files, and autoreplies, the duplicate checking
3154 still happens during the routing process, since they are not going to be
3155 routed further.

3168 to spool files. There was no check on this. Now the value is run through
3169 the string_printing() function so that such characters are converted to
3170 printable escape sequences.

3176PH/42 Exim no longer gives details of delivery errors for specific addresses in
3177 bounce and delay warning messages, except in certain special cases, which
3178 are as follows:
3179
3180 (a) An SMTP error message from a remote host;
3181 (b) A message specified in a :fail: redirection;
3182 (c) A message specified in a "fail" command in a system filter;
3183 (d) A message specified in a FAIL return from the queryprogram router;
3184 (e) A message specified by the cannot_route_message router option.
3185
3186 In these cases only, Exim does include the error details in bounce and
3187 warning messages. There are also a few cases where bland messages such
3188 as "unrouteable address" or "local delivery error" are given.

3196PH/45 In a pipe transport, although a timeout while waiting for the pipe
3197 process to complete was treated as a delivery failure, a timeout while
3198 writing the message to the pipe was logged, but erroneously treated as a
3199 successful delivery. Such timeouts include transport filter timeouts. For
3200 consistency with the overall process timeout, these timeouts are now
3201 treated as errors, giving rise to delivery failures by default. However,
3202 there is now a new Boolean option for the pipe transport called
3203 timeout_defer, which, if set TRUE, converts the failures into defers for
3204 both kinds of timeout. A transport filter timeout is now identified in
3205 the log output.

3210 from the Makefile to this script so that it can call the same version of

3214A note about Exim versions 4.44 and 4.50
3215----------------------------------------
3216
3217Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3218changes of various kinds. As a consequence, a big documentation update was
3219needed. This delayed the release for rather longer than seemed good, especially
3220in the light of a couple of (minor) security issues. Therefore, the changes
3221that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3222release. So 4.44 and 4.50 are in effect two different branches that both start
3223from 4.43.
3224
3225I have left the 4.50 change log unchanged; it contains all the changes since
32264.43. The change log for 4.44 is below; many of its items are identical to
3227those for 4.50. This seems to be the most sensible way to preserve the
3228historical information.

3234 1. Minor wording change to the doc/README.SIEVE file.
3235
139059f6 3236 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 3237 computation of the current number of files was incorrect.

3239 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3240 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3241 place.

3243 4. Give more explanation in the error message when the command for a transport
3244 filter fails to execute.

PH
3246 5. There are several places where Exim runs a non-Exim command in a
3247 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3248 was being done only for the command run by the queryprogram router. It is
3249 now done for all such subprocesses. The other cases are: ${run, transport
3250 filters, and the commands run by the lmtp and pipe transports.

3252 6. Added CONFIGURE_GROUP build-time option.
3253
3254 7. Some older OS have a limit of 256 on the maximum number of file
3255 descriptors. Exim was using setrlimit() to set 1000 as a large value
3256 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3257 systems. I've change it so that if it can't get 1000, it tries for 256.

3259 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3260 was an oversight, and furthermore, ever since the addition of extra
3261 controls (e.g. 4.43/32), the checks on when to allow different forms of
3262 "control" were broken. There should now be diagnostics for all cases when a
3263 control that does not make sense is encountered.

326911. Tidy the search cache before the fork to do a delivery from a message
3270 received from the command line. Otherwise the child will trigger a lookup
3271 failure and thereby defer the delivery if it tries to use (for example) a
3272 cached ldap connection that the parent has called unbind on.

327412. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3275 of $address_data from the recipient verification was clobbered by the
3276 sender verification.

327813. The value of address_data from a sender verification is now available in
3279 $sender_address_data in subsequent conditions in the ACL statement.

330422. $host_address is now set to the target address during the checking of
3305 ignore_target_hosts.
3306
330723. When checking ignore_target_hosts for an ipliteral router, no host name was
3308 being passed; this would have caused $sender_host_name to have been used if
3309 matching the list had actually called for a host name (not very likely,
3310 since this list is usually IP addresses). A host name is now passed as
3311 "[x.x.x.x]".
3312

PH
331324. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3314 code that specifies a non-restarting handler (typically sigaction() in
3315 modern systems) in an attempt to fix a rare and obscure crash bug.
3316
331725. Narrowed the window for a race in the daemon that could cause it to ignore
3318 SIGCHLD signals. This is not a major problem, because they are used only to
3319 wake it up if nothing else does.

332126. A malformed maildirsize file could cause Exim to calculate negative values
3322 for the mailbox size or file count. Odd effects could occur as a result.
3323 The maildirsize information is now recalculated if the size or filecount
3324 end up negative.

333129. In an address list, if the pattern was not a regular expression, an empty
3332 subject address (from a bounce message) matched only if the pattern was an
3333 empty string. Non-empty patterns were not even tested. This was the wrong
3334 because it is perfectly reasonable to use an empty address as part of a
3335 database query. An empty address is now tested by patterns that are
3336 lookups. However, all the other forms of pattern expect the subject to
3337 contain a local part and a domain, and therefore, for them, an empty
3338 address still always fails if the pattern is not itself empty.

334030. Exim went into a mad DNS loop when attempting to do a callout where the
3341 host was specified on an smtp transport, and looking it up yielded more
3342 than one IP address.
3343

PH
334431. Re-factored the code for checking spool and log partition space into a
3345 function that finds that data and another that does the check. The former
3346 is then used to implement four new variables: $spool_space, $log_space,
3347 $spool_inodes, and $log_inodes.
3348

PH
334932. The RFC2047 encoding function was originally intended for short strings
3350 such as real names; it was not keeping to the 75-character limit for
3351 encoded words that the RFC imposes. It now respects the limit, and
3352 generates multiple encoded words if necessary. To be on the safe side, I
3353 have increased the buffer size for the ${rfc2047: expansion operator from
3354 1024 to 2048 bytes.
3355

PH
335633. It is now permitted to omit both strings after an "if" condition; if the
3357 condition is true, the result is "true". As before, when the second string
3358 is omitted, a false condition yields an empty string. This makes it less
3359 cumbersome to write custom ACL and router conditions.
3360
652e1b65
PH
336134. Failure to deliver a bounce message always caused it to be frozen, even if
3362 there was an errors_to setting on the router. The errors_to setting is now
3363 respected.
3364

PH
336535. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3366 canonical form (fully expanded) before being placed in
3367 $sender_host_address.
3368

PH
336936. The table in the code that translates DNS record types into text (T_A to
3370 "A" for instance) was missing entries for NS and CNAME. It is just possible
3371 that this could have caused confusion if both these types were looked up
3372 for the same domain, because the text type is used as part of Exim's
3373 per-process caching. But the chance of anyone hitting this buglet seems
3374 very small.
3375

PH
337637. The dnsdb lookup has been extended in a number of ways.
3377
3378 (1) There is a new type, "zns", which walks up the domain tree until it
3379 finds some nameserver records. It should be used with care.
3380

PH
3381 (2) There is a new type, "mxh", which is like "mx" except that it returns
3382 just the host names, not the priorities.
3383
3384 (3) It is now possible to give a list of domains (or IP addresses) to be

3385 looked up. The behaviour when one of the lookups defers can be
3386 controlled by a keyword.
