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.

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".

182 an empty string is now equivalent.

376TF/03 Make the exiwhat support code safe for signals. Previously Exim might
377 lock up or crash if it happened to be inside a call to libc when it
378 got a SIGUSR1 from exiwhat.
379
380 The SIGUSR1 handler appends the current process status to the process
381 log which is later printed by exiwhat. It used to use the general
382 purpose logging code to do this, but several functions it calls are
383 not safe for signals.
384
385 The new output code in the SIGUSR1 handler is specific to the process
386 log, and simple enough that it's easy to inspect for signal safety.
387 Removing some special cases also simplifies the general logging code.
388 Removing the spurious timestamps from the process log simplifies
389 exiwhat.

c99ce5c9
TF
391TF/04 Improved ratelimit ACL condition.
392
393 The /noupdate option has been deprecated in favour of /readonly which
394 has clearer semantics. The /leaky, /strict, and /readonly update modes
395 are mutually exclusive. The update mode is no longer included in the
396 database key; it just determines when the database is updated. (This
397 means that when you upgrde Exim will forget old rate measurements.)
398
399 Exim now checks that the per_* options are used with an update mode that
400 makes sense for the current ACL. For example, when Exim is processing a
401 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
402 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
403 must specify per_mail/readonly. If you omit the update mode it defaults to
404 /leaky where that makes sense (as before) or /readonly where required.
405
406 The /noupdate option is now undocumented but still supported for
407 backwards compatibility. It is equivalent to /readonly except that in
408 ACLs where /readonly is required you may specify /leaky/noupdate or
409 /strict/noupdate which are treated the same as /readonly.
410
411 A useful new feature is the /count= option. This is a generalization
412 of the per_byte option, so that you can measure the throughput of other
413 aggregate values. For example, the per_byte option is now equivalent
414 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
415
416 The per_rcpt option has been generalized using the /count= mechanism
417 (though it's more complicated than the per_byte equivalence). When it is
418 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
419 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
420 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
421 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
422 Note that using per_rcpt with a non-readonly update mode in more than
423 one ACL will cause the recipients to be double-counted. (The per_mail
424 and per_byte options don't have this problem.)
425
426 The handling of very low rates has changed slightly. If the computed rate
427 is less than the event's count (usually one) then this event is the first
428 after a long gap. In this case the rate is set to the same as this event's
429 count, so that the first message of a spam run is counted properly.
430
431 The major new feature is a mechanism for counting the rate of unique
432 events. The new per_addr option counts the number of different
433 recipients that someone has sent messages to in the last time period. It
434 behaves like per_rcpt if all the recipient addresses are different, but
435 duplicate recipient addresses do not increase the measured rate. Like
436 the /count= option this is a general mechanism, so the per_addr option
437 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
438 example, measure the rate that a client uses different sender addresses
439 with the options per_mail/unique=$sender_address. There are further
440 details in the main documentation.

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

1012PH/01 Another patch from the Sieve maintainer.
1013
6a3bceb1
PH
1014PH/02 When an IPv6 address is converted to a string for single-key lookup
1015 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1016 dots are used instead of colons so that keys in lsearch files need not
1017 contain colons. This was done some time before quoting was made available
1018 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1019 (notated using the quote facility) so as to distinguish them from IPv4
1020 keys. This meant that lookups for IP addresses in host lists did not work
1021 for iplsearch lookups.
1022
1023 This has been fixed by arranging for IPv6 addresses to be expressed with
1024 colons if the lookup type is iplsearch. This is not incompatible, because
1025 previously such lookups could never work.
1026
1027 The situation is now rather anomolous, since one *can* have colons in
1028 ordinary lsearch keys. However, making the change in all cases is
1029 incompatible and would probably break a number of configurations.

1034MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1035 conversion specification without a maximum field width, thereby enabling
1036 a rogue spamd server to cause a buffer overflow. While nobody in their
1037 right mind would setup Exim to query an untrusted spamd server, an
1038 attacker that gains access to a server running spamd could potentially
1039 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1044MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1045 a directory entry by the name of the lookup key. Previously, if a
1046 symlink pointed to a non-existing file or a file in a directory that
1047 Exim lacked permissions to read, a lookup for a key matching that
1048 symlink would fail. Now it is enough that a matching directory entry
1049 exists, symlink or not. (Bugzilla 503.)

PH
1232PH/29 SMTP synchronization checks are implemented when a command is read -
1233 there is a check that no more input is waiting when there shouldn't be
1234 any. However, for some commands, a delay in an ACL can mean that it is
1235 some time before the response is written. In this time, more input might
1236 arrive, invalidly. So now there are extra checks after an ACL has run for
1237 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1238 pipelining has not been advertised.

1312 the response to the final '.' that terminates a message, but only in the
1313 case where the client has not sent further data following the '.'
1314 (unfortunately, this is allowed). However, in many cases there won't be
1315 any further data because there won't be any more messages to send. A call
1316 to select() can be used: if it shows that the input is "ready", there is
1317 either input waiting, or the socket has been closed. An attempt to read
1318 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1319 would have sent an OK response which the client would never have see.

1330PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1331 fixed by 4.65/MH/01 (is this a record?) are fixed:
1332
1333 (i) An empty string was always treated as zero by the numeric comparison
1334 operators. This behaviour has been restored.
1335
1336 (ii) It is documented that the numeric comparison operators always treat
1337 their arguments as decimal numbers. This was broken in that numbers
1338 starting with 0 were being interpreted as octal.
1339
1340 While fixing these problems I realized that there was another issue that
1341 hadn't been noticed. Values of message_size_limit (both the global option
1342 and the transport option) were treated as octal if they started with 0.
1343 The documentation was vague. These values are now always treated as
1344 decimal, and I will make that clear in the documentation.

1361 large number of recipients for a single message is ridiculous
1362 (performance will be very, very poor), I have chosen to impose a limit
1363 rather than extend the field.

2b1c6e3a
PH
1388PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1389 callout verification, Exim cached a "reject" for the entire domain. This
1390 is correct for most verifications, but it is not correct for a recipient
1391 verification with use_sender or use_postmaster set, because in that case
1392 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1393 case of MAIL FROM:<> rejection from other early rejections (e.g.
1394 rejection of HELO). When verifying a recipient using a non-null MAIL
1395 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1396 Whatever the result of the callout, the value of the domain cache is
1397 left unchanged (for any other kind of callout, getting as far as trying
1398 RCPT means that the domain itself is ok).

1432PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1434 probably the interface on which it is arriving) and not to the outgoing
1435 callout (which could be using a different interface). This has been
1436 changed to use the value of the helo_data option from the smtp transport
1437 instead - this is what is used when a message is actually being sent. If
1438 there is no remote transport (possible with a router that sets up host
1439 addresses), $smtp_active_hostname is used.

7befa435 1442 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1443 (a) The code assumed that strncpy() returns a negative number on buffer
1444 overflow, which isn't the case. Replaced with Exim's string_format()
1445 function.
1446 (b) There were several signed/unsigned issues. I just did the minimum
1447 hacking in of casts. There is scope for a larger refactoring.
1448 (c) The code used strcasecmp() which is not a standard C function.
1449 Replaced with Exim's strcmpic() function.
1450 (d) The code set only $1; it now sets $auth1 as well.
1451 (e) A simple test gave the error "authentication client didn't specify
1452 service in request". It would seem that Dovecot has changed its
1453 interface. Fortunately there's a specification; I followed it and
1454 changed what the client sends and it appears to be working now.

1460 address A is aliased to B and C, where B exists and C does not. Without
1461 -v the output is "A verified" because verification stops after a
1462 successful redirection if more than one address is generated. However,
1463 with -v the child addresses are also verified. Exim was outputting "A
1464 failed to verify" and then showing the successful verification for C,
1465 with its parentage. It now outputs "B failed to verify", showing B's
1466 parentage before showing the successful verification of C.

1471
322050c2
PH
1472PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1473 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1474 they consult the DNS. I had assumed they would set it the way they
1475 wanted; and indeed my experiments on Linux seem to show that in some
1476 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1477 To be on the safe side, however, I have now made the interface to
1478 host_find_byname() similar to host_find_bydns(), with an argument
1479 containing the DNS resolver options. The host_find_byname() function now
1480 sets these options at its start, just as host_find_bydns() does. The smtp
1481 transport options dns_qualify_single and dns_search_parents are passed to
1482 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1483 of host_find_byname() use the default settings of RES_DEFNAMES
1484 (qualify_single) but not RES_DNSRCH (search_parents).

1486PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1487 spool_read_header() do less string testing, by means of a preliminary
1488 switch on the second character of optional "-foo" lines. (This is
1489 overdue, caused by the large number of possibilities that now exist.
1490 Originally there were few.) While I was there, I also converted the
1491 str(n)cmp tests so they don't re-test the leading "-" and the first
1492 character, in the hope this might squeeze out yet more improvement.

PH
1494PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1495 flag allowing group syntax was set by the header_syntax check but not
1496 turned off, possible causing trouble later; (2) The flag was not being
1497 set at all for the header_verify test, causing "group"-style headers to
1498 be rejected. I have now set it in this case, and also caused header_
1499 verify to ignore an empty address taken from a group. While doing this, I
1500 came across some other cases where the code for allowing group syntax
1501 while scanning a header line wasn't quite right (mostly, not resetting
1502 the flag correctly in the right place). These bugs could have caused
1503 trouble for malformed header lines. I hope it is now all correct.

PH
1505PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1506 with the "reply" argument non-NULL. The code, however (which originally
1507 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1508 but it didn't always do it. This confused somebody who was copying the
1509 code for some other use. I have removed all the tests.

PH
1511PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1512 feature that was used to support insecure browsers during the U.S. crypto
1513 embargo. It requires special client support, and Exim is probably the
1514 only MTA that supported it -- and would never use it because real RSA is
1515 always available. This code has been removed, because it had the bad
1516 effect of slowing Exim down by computing (never used) parameters for the
1517 RSA_EXPORT functionality.

1522 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1523 if the connection is using TLS or if the remote IP is the same as the
1524 local IP, and the "valid-client-cert option" if a client certificate has
1525 been verified.

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

1600PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1601 runs only) independently of the message's sender address. This meant
1602 that, if the 4xx error was in fact related to the sender, a different
1603 message to the same recipient with a different sender could confuse
1604 things. In particualar, this can happen when sending to a greylisting
1605 server, but other circumstances could also provoke similar problems.
1606 I have changed the default so that the retry time for these errors is now
1607 based a combination of the sender and recipient addresses. This change
1608 can be overridden by setting address_retry_include_sender=false in the
1609 smtp transport.

1880 tcp-wrappers gives "deny", whereas what one would like would be some
1881 kind of temporary error. A kludge has been added to help with this.
1882 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1883 554 error is used if errno is still zero or contains ENOENT (which occurs
1884 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1971 name, causing unrelated and misleading errors. What now happens is that
1972 it logs this as a hard delivery error, but does not attempt to create a

2004PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2005 additional section of a DNS packet that returns MX or SRV records.
2006 Instead, it always explicitly searches for A/AAAA records. This avoids
2007 major problems that occur when a DNS server includes only records of one
2008 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2009 fixed another bug: if SRV records were looked up and the corresponding
2010 address records were *not* found in the additional section, the port
2011 values from the SRV records were lost.

2021PH/19 When calculating a retry time, Exim used to measure the "time since
2022 failure" by looking at the "first failed" field in the retry record. Now
2023 it does not use this if it is later than than the arrival time of the
2024 message. Instead it uses the arrival time. This makes for better
2025 behaviour in cases where some deliveries succeed, thus re-setting the
2026 "first failed" field. An example is a quota failure for a huge message
2027 when small messages continue to be delivered. Without this change, the
2028 "time since failure" will always be short, possible causing more frequent
2029 delivery attempts for the huge message than are intended.

2126PH/42 The content-scanning code uses fopen() to create files in which to put
2127 message data. Previously it was not paying any attention to the mode of
2128 the files. Exim runs with umask(0) because the rest of the code creates
2129 files with open(), and sets the required mode explicitly. Thus, these
2130 files were ending up world-writeable. This was not a big issue, because,
2131 being within the spool directory, they were not world-accessible. I have
2132 created a function called modefopen, which takes an additional mode
2133 argument. It sets umask(777), creates the file, chmods it to the required
2134 mode, then resets the umask. All the relevant calls to fopen() in the
2135 content scanning code have been changed to use this function.

2172
2173 (i) Exim was not creating retry information for temporary errors given
2174 for individual recipients after the DATA command when the smtp transport
2175 was used in LMTP mode. This meant that they could be retried too
2176 frequently, and not timed out correctly.
2177
2178 (ii) Exim was setting the flag that allows error details to be returned
2179 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2180 recipients that were returned after the DATA command.
2181
2182PH/53 This is related to PH/52, but is more general: for any failing address,
2183 when detailed error information was permitted to be returned to the

2256PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2257 function verify_get_ident() calls ip_connect() to connect a socket, but
2258 if the "connect()" function timed out, ip_connect() used to close the
2259 socket. However, verify_get_ident() also closes the socket later, and in
2260 between Exim writes to the log, which may get opened at this point. When
2261 the socket was closed in ip_connect(), the log could get the same file
2262 descriptor number as the socket. This naturally causes chaos. The fix is
2263 not to close the socket in ip_connect(); the socket should be closed by
2264 the function that creates it. There was only one place in the code where
2265 this was missing, in the iplookup router, which I don't think anybody now
2266 uses, but I've fixed it anyway.

2328 Received: from [1.2.3.4] (helo=[1.2.3.4])

2366 hyphen). Since every message generated by Exim is necessarily in response
2367 to another message, thes have all been changed to:
2368
2369 Auto-Submitted: auto-replied
2370
2371 in accordance with these statements in the RFC:
2372
2373 The auto-replied keyword:
2374
2375 - SHOULD be used on messages sent in direct response to another
2376 message by an automatic process,
2377
2378 - MUST NOT be used on manually-generated messages,
2379
2380 - MAY be used on Delivery Status Notifications (DSNs) and Message
2381 Disposition Notifications (MDNs),
2382
2383 - MUST NOT be used on messages generated by automatic or periodic
2384 processes, except for messages which are automatic responses to
2385 other messages.

2409 nobody wrote the draft yet. This extension is currently #undef'ed, thus

PH
2421PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2422 canonical form (as documented). However, after a host name lookup from
2423 the IP address, check_host() was doing a simple string comparison with
2424 addresses acquired from the DNS when checking that the found name did
2425 have the original IP as one of its addresses. Since any found IPv6
2426 addresses are likely to be in abbreviated form, the comparison could
2427 fail. Luckily, there already exists a function for doing the comparison
2428 by converting both addresses to binary, so now that is used instead of
2429 the text comparison.

PH
2431PH/20 There was another similar case to PH/19, when a complete host name was

2729 preserve the sysexits.h value, by assumimg that macro definitions were

2814 case the guess is not the same as the compiled default, so the script
2815 suddenly stopped working when I started to use syslog. The patch checks

2946
2947PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2948 that changes the way the GnuTLS parameters are stored in the cache file.
2949 The new format can be generated externally. For backward compatibility,
2950 if the data in the cache doesn't make sense, Exim assumes it has read an
2951 old-format file, and it generates new data and writes a new file. This
2952 means that you can't go back to an older release without removing the
2953 file.
2954
2955PH/03 A redirect router that has both "unseen" and "one_time" set does not
2956 work if there are any delivery delays because "one_time" forces the
2957 parent to be marked "delivered", so its unseen clone is never tried
2958 again. For this reason, Exim now forbids the simultaneous setting of
2959 these two options.
2960
2961PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2962 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2963 entry if you want to know the details. The fix, however, neglected to
2964 consider the case when local delivery batching is involved. The test for
2965 "previously delivered" was not happening when checking to see if an
2966 address could be batched with a previous (undelivered) one; under
2967 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2968 address.

2973PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2974 header_syntax) but Exim was just ignoring anything given after a slash.
2975 In particular, this caused confusion with an attempt to use "verify =
2976 reverse_host_lookup/defer_ok". An error is now given when options are
2977 supplied for verify items that do not have them. (Maybe reverse_host_
2978 lookup should have a defer_ok option, but that's a different point.)

2980PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3033 the file with the wrong ownership). There was no test for failure of this
3034 fork() call, which would lead to the process getting stuck as it waited
3035 for a non-existent subprocess. Forks do occasionally fail when resources

3043 string after "input=" when read() returned zero. If read() returned -1

3056PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3057 hadn't been configured. The fix is from Juergen Kreileder, who
3058 understands it better than I do:
3059
3060 "Here's what I see happening with three configured cyrus_sasl
3061 authenticators configured (plain, login, cram-md5):
3062
3063 On startup auth_cyrus_sasl_init() gets called for each of these.
3064 This means three calls to sasl_listmech() without a specified mech_list.
3065 => SASL tests which mechs of all available mechs actually work
3066 => three warnings about OTP not working
3067 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3068
3069 With the patch, sasl_listmech() also gets called three times. But now
3070 SASL's mech_list option is set to the server_mech specified in the the
3071 authenticator. Or in other words, the answer from sasl_listmech()
3072 gets limited to just the mech you're testing for (which is different
3073 for each call.)
3074 => the return list contains just 'plain' or 'login', 'cram-md5' or
3075 nothing depending on the value of ob->server_mech.
3076

PH
3143PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3144 the grounds that routing the same address twice would always produce the
3145 same answer. This might have been true once, but it is certainly no
3146 longer true now. Routing a child address may depend on the previous
3147 routing that produced that child. Some complicated redirection strategies
3148 went wrong when messages had multiple recipients, and made Exim's
3149 behaviour dependent on the order in which the addresses were given.
3150
3151 I have moved the duplicate checking until after the routing is complete.
3152 Exim scans the addresses that are assigned to local and remote
3153 transports, and removes any duplicates. This means that more work will be
3154 done, as duplicates will always all be routed, but duplicates are
3155 presumably rare, so I don't expect this is of any significance.
3156
3157 For deliveries to pipes, files, and autoreplies, the duplicate checking
3158 still happens during the routing process, since they are not going to be
3159 routed further.

3163 background is that sometimes spamd either never reads data from a
3164 connection it has accepted, or it never writes response data. The exiscan
3165 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3166 blindly assumes that writes won't block so it may never time out."

3180PH/42 Exim no longer gives details of delivery errors for specific addresses in
3181 bounce and delay warning messages, except in certain special cases, which
3182 are as follows:
3183
3184 (a) An SMTP error message from a remote host;
3185 (b) A message specified in a :fail: redirection;
3186 (c) A message specified in a "fail" command in a system filter;
3187 (d) A message specified in a FAIL return from the queryprogram router;
3188 (e) A message specified by the cannot_route_message router option.
3189
3190 In these cases only, Exim does include the error details in bounce and
3191 warning messages. There are also a few cases where bland messages such
3192 as "unrouteable address" or "local delivery error" are given.

3200PH/45 In a pipe transport, although a timeout while waiting for the pipe
3201 process to complete was treated as a delivery failure, a timeout while
3202 writing the message to the pipe was logged, but erroneously treated as a
3203 successful delivery. Such timeouts include transport filter timeouts. For
3204 consistency with the overall process timeout, these timeouts are now
3205 treated as errors, giving rise to delivery failures by default. However,
3206 there is now a new Boolean option for the pipe transport called
3207 timeout_defer, which, if set TRUE, converts the failures into defers for
3208 both kinds of timeout. A transport filter timeout is now identified in
3209 the log output.

3218A note about Exim versions 4.44 and 4.50
3219----------------------------------------
3220
3221Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3222changes of various kinds. As a consequence, a big documentation update was
3223needed. This delayed the release for rather longer than seemed good, especially
3224in the light of a couple of (minor) security issues. Therefore, the changes
3225that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3226release. So 4.44 and 4.50 are in effect two different branches that both start
3227from 4.43.
3228
3229I have left the 4.50 change log unchanged; it contains all the changes since
32304.43. The change log for 4.44 is below; many of its items are identical to
3231those for 4.50. This seems to be the most sensible way to preserve the
3232historical information.

3250 5. There are several places where Exim runs a non-Exim command in a
3251 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3252 was being done only for the command run by the queryprogram router. It is
3253 now done for all such subprocesses. The other cases are: ${run, transport
3254 filters, and the commands run by the lmtp and pipe transports.

3256 6. Added CONFIGURE_GROUP build-time option.
3257
3258 7. Some older OS have a limit of 256 on the maximum number of file
3259 descriptors. Exim was using setrlimit() to set 1000 as a large value
3260 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3261 systems. I've change it so that if it can't get 1000, it tries for 256.

3263 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3264 was an oversight, and furthermore, ever since the addition of extra
3265 controls (e.g. 4.43/32), the checks on when to allow different forms of
3266 "control" were broken. There should now be diagnostics for all cases when a
3267 control that does not make sense is encountered.

3276 cached ldap connection that the parent has called unbind on.

327812. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3279 of $address_data from the recipient verification was clobbered by the
3280 sender verification.

3283 $sender_address_data in subsequent conditions in the ACL statement.

330822. $host_address is now set to the target address during the checking of
3309 ignore_target_hosts.
3310
331123. When checking ignore_target_hosts for an ipliteral router, no host name was
3312 being passed; this would have caused $sender_host_name to have been used if
3313 matching the list had actually called for a host name (not very likely,
3314 since this list is usually IP addresses). A host name is now passed as
3315 "[x.x.x.x]".
3316

PH
331724. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3318 code that specifies a non-restarting handler (typically sigaction() in
3319 modern systems) in an attempt to fix a rare and obscure crash bug.
3320
332125. Narrowed the window for a race in the daemon that could cause it to ignore
3322 SIGCHLD signals. This is not a major problem, because they are used only to
3323 wake it up if nothing else does.

332526. A malformed maildirsize file could cause Exim to calculate negative values
3326 for the mailbox size or file count. Odd effects could occur as a result.
3327 The maildirsize information is now recalculated if the size or filecount
3328 end up negative.

333529. In an address list, if the pattern was not a regular expression, an empty
3336 subject address (from a bounce message) matched only if the pattern was an
3337 empty string. Non-empty patterns were not even tested. This was the wrong
3338 because it is perfectly reasonable to use an empty address as part of a
3339 database query. An empty address is now tested by patterns that are
3340 lookups. However, all the other forms of pattern expect the subject to
3341 contain a local part and a domain, and therefore, for them, an empty
3342 address still always fails if the pattern is not itself empty.

334430. Exim went into a mad DNS loop when attempting to do a callout where the
3345 host was specified on an smtp transport, and looking it up yielded more
3346 than one IP address.

PH
334831. Re-factored the code for checking spool and log partition space into a
3349 function that finds that data and another that does the check. The former
3350 is then used to implement four new variables: $spool_space, $log_space,
3351 $spool_inodes, and $log_inodes.

PH
335332. The RFC2047 encoding function was originally intended for short strings
3354 such as real names; it was not keeping to the 75-character limit for
3355 encoded words that the RFC imposes. It now respects the limit, and
3356 generates multiple encoded words if necessary. To be on the safe side, I
3357 have increased the buffer size for the ${rfc2047: expansion operator from
3358 1024 to 2048 bytes.
3359
063b1e99
PH
336033. It is now permitted to omit both strings after an "if" condition; if the
3361 condition is true, the result is "true". As before, when the second string
3362 is omitted, a false condition yields an empty string. This makes it less
3363 cumbersome to write custom ACL and router conditions.
3364
652e1b65
PH
336534. Failure to deliver a bounce message always caused it to be frozen, even if
3366 there was an errors_to setting on the router. The errors_to setting is now
3367 respected.

PH
336935. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3370 canonical form (fully expanded) before being placed in
3371 $sender_host_address.
3372
33397d19
PH
337336. The table in the code that translates DNS record types into text (T_A to
3374 "A" for instance) was missing entries for NS and CNAME. It is just possible
3375 that this could have caused confusion if both these types were looked up
3376 for the same domain, because the text type is used as part of Exim's
3377 per-process caching. But the chance of anyone hitting this buglet seems
3378 very small.
3379
7bb56e1f
PH
338037. The dnsdb lookup has been extended in a number of ways.
3381
3382 (1) There is a new type, "zns", which walks up the domain tree until it
3383 finds some nameserver records. It should be used with care.
