TF
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.

TF
334TF/03 Make the exiwhat support code safe for signals. Previously Exim might
335 lock up or crash if it happened to be inside a call to libc when it
336 got a SIGUSR1 from exiwhat.
337
338 The SIGUSR1 handler appends the current process status to the process
339 log which is later printed by exiwhat. It used to use the general
340 purpose logging code to do this, but several functions it calls are
341 not safe for signals.
342
343 The new output code in the SIGUSR1 handler is specific to the process
344 log, and simple enough that it's easy to inspect for signal safety.
345 Removing some special cases also simplifies the general logging code.
346 Removing the spurious timestamps from the process log simplifies
347 exiwhat.

TF
349TF/04 Improved ratelimit ACL condition.
350
351 The /noupdate option has been deprecated in favour of /readonly which
352 has clearer semantics. The /leaky, /strict, and /readonly update modes
353 are mutually exclusive. The update mode is no longer included in the
354 database key; it just determines when the database is updated. (This
355 means that when you upgrde Exim will forget old rate measurements.)
356
357 Exim now checks that the per_* options are used with an update mode that
358 makes sense for the current ACL. For example, when Exim is processing a
359 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
360 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
361 must specify per_mail/readonly. If you omit the update mode it defaults to
362 /leaky where that makes sense (as before) or /readonly where required.
363
364 The /noupdate option is now undocumented but still supported for
365 backwards compatibility. It is equivalent to /readonly except that in
366 ACLs where /readonly is required you may specify /leaky/noupdate or
367 /strict/noupdate which are treated the same as /readonly.
368
369 A useful new feature is the /count= option. This is a generalization
370 of the per_byte option, so that you can measure the throughput of other
371 aggregate values. For example, the per_byte option is now equivalent
372 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
373
374 The per_rcpt option has been generalized using the /count= mechanism
375 (though it's more complicated than the per_byte equivalence). When it is
376 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
377 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
378 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
379 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
380 Note that using per_rcpt with a non-readonly update mode in more than
381 one ACL will cause the recipients to be double-counted. (The per_mail
382 and per_byte options don't have this problem.)
383
384 The handling of very low rates has changed slightly. If the computed rate
385 is less than the event's count (usually one) then this event is the first
386 after a long gap. In this case the rate is set to the same as this event's
387 count, so that the first message of a spam run is counted properly.
388
389 The major new feature is a mechanism for counting the rate of unique
390 events. The new per_addr option counts the number of different
391 recipients that someone has sent messages to in the last time period. It
392 behaves like per_rcpt if all the recipient addresses are different, but
393 duplicate recipient addresses do not increase the measured rate. Like
394 the /count= option this is a general mechanism, so the per_addr option
395 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
396 example, measure the rate that a client uses different sender addresses
397 with the options per_mail/unique=$sender_address. There are further
398 details in the main documentation.

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

970PH/01 Another patch from the Sieve maintainer.
971
6a3bceb1
PH
972PH/02 When an IPv6 address is converted to a string for single-key lookup
973 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
974 dots are used instead of colons so that keys in lsearch files need not
975 contain colons. This was done some time before quoting was made available
976 in lsearch files. However, iplsearch files do require colons in IPv6 keys
977 (notated using the quote facility) so as to distinguish them from IPv4
978 keys. This meant that lookups for IP addresses in host lists did not work
979 for iplsearch lookups.
980
981 This has been fixed by arranging for IPv6 addresses to be expressed with
982 colons if the lookup type is iplsearch. This is not incompatible, because
983 previously such lookups could never work.
984
985 The situation is now rather anomolous, since one *can* have colons in
986 ordinary lsearch keys. However, making the change in all cases is
987 incompatible and would probably break a number of configurations.

992MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
993 conversion specification without a maximum field width, thereby enabling
994 a rogue spamd server to cause a buffer overflow. While nobody in their
995 right mind would setup Exim to query an untrusted spamd server, an
996 attacker that gains access to a server running spamd could potentially
997 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1002MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1003 a directory entry by the name of the lookup key. Previously, if a
1004 symlink pointed to a non-existing file or a file in a directory that
1005 Exim lacked permissions to read, a lookup for a key matching that
1006 symlink would fail. Now it is enough that a matching directory entry
1007 exists, symlink or not. (Bugzilla 503.)

1193 some time before the response is written. In this time, more input might
1194 arrive, invalidly. So now there are extra checks after an ACL has run for
1195 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1196 pipelining has not been advertised.

1211 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1212 was a macro that became an assignment, so it seemed to work. This has

1272 (unfortunately, this is allowed). However, in many cases there won't be
1273 any further data because there won't be any more messages to send. A call
1274 to select() can be used: if it shows that the input is "ready", there is
1275 either input waiting, or the socket has been closed. An attempt to read
1276 the next input character can distinguish the two cases. Previously, Exim

1288PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1289 fixed by 4.65/MH/01 (is this a record?) are fixed:
1290
1291 (i) An empty string was always treated as zero by the numeric comparison
1292 operators. This behaviour has been restored.
1293
1294 (ii) It is documented that the numeric comparison operators always treat
1295 their arguments as decimal numbers. This was broken in that numbers
1296 starting with 0 were being interpreted as octal.
1297
1298 While fixing these problems I realized that there was another issue that
1299 hadn't been noticed. Values of message_size_limit (both the global option
1300 and the transport option) were treated as octal if they started with 0.
1301 The documentation was vague. These values are now always treated as
1302 decimal, and I will make that clear in the documentation.

1319 large number of recipients for a single message is ridiculous
1320 (performance will be very, very poor), I have chosen to impose a limit
1321 rather than extend the field.

PH
1346PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1347 callout verification, Exim cached a "reject" for the entire domain. This
1348 is correct for most verifications, but it is not correct for a recipient
1349 verification with use_sender or use_postmaster set, because in that case
1350 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1351 case of MAIL FROM:<> rejection from other early rejections (e.g.
1352 rejection of HELO). When verifying a recipient using a non-null MAIL
1353 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1354 Whatever the result of the callout, the value of the domain cache is
1355 left unchanged (for any other kind of callout, getting as far as trying
1356 RCPT means that the domain itself is ok).

1392 probably the interface on which it is arriving) and not to the outgoing
1393 callout (which could be using a different interface). This has been
1394 changed to use the value of the helo_data option from the smtp transport
1395 instead - this is what is used when a message is actually being sent. If
1396 there is no remote transport (possible with a router that sets up host

7befa435 1400 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1401 (a) The code assumed that strncpy() returns a negative number on buffer
1402 overflow, which isn't the case. Replaced with Exim's string_format()
1403 function.
1404 (b) There were several signed/unsigned issues. I just did the minimum
1405 hacking in of casts. There is scope for a larger refactoring.
1406 (c) The code used strcasecmp() which is not a standard C function.
1407 Replaced with Exim's strcmpic() function.
1408 (d) The code set only $1; it now sets $auth1 as well.
1409 (e) A simple test gave the error "authentication client didn't specify
1410 service in request". It would seem that Dovecot has changed its
1411 interface. Fortunately there's a specification; I followed it and
1412 changed what the client sends and it appears to be working now.

1418 address A is aliased to B and C, where B exists and C does not. Without
1419 -v the output is "A verified" because verification stops after a
1420 successful redirection if more than one address is generated. However,
1421 with -v the child addresses are also verified. Exim was outputting "A
1422 failed to verify" and then showing the successful verification for C,
1423 with its parentage. It now outputs "B failed to verify", showing B's
1424 parentage before showing the successful verification of C.

PH
1430PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1431 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1432 they consult the DNS. I had assumed they would set it the way they
1433 wanted; and indeed my experiments on Linux seem to show that in some
1434 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1435 To be on the safe side, however, I have now made the interface to
1436 host_find_byname() similar to host_find_bydns(), with an argument
1437 containing the DNS resolver options. The host_find_byname() function now
1438 sets these options at its start, just as host_find_bydns() does. The smtp
1439 transport options dns_qualify_single and dns_search_parents are passed to
1440 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1441 of host_find_byname() use the default settings of RES_DEFNAMES
1442 (qualify_single) but not RES_DNSRCH (search_parents).

1444PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1445 spool_read_header() do less string testing, by means of a preliminary
1446 switch on the second character of optional "-foo" lines. (This is
1447 overdue, caused by the large number of possibilities that now exist.
1448 Originally there were few.) While I was there, I also converted the
1449 str(n)cmp tests so they don't re-test the leading "-" and the first
1450 character, in the hope this might squeeze out yet more improvement.

1452PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1453 flag allowing group syntax was set by the header_syntax check but not
1454 turned off, possible causing trouble later; (2) The flag was not being
1455 set at all for the header_verify test, causing "group"-style headers to
1456 be rejected. I have now set it in this case, and also caused header_
1457 verify to ignore an empty address taken from a group. While doing this, I
1458 came across some other cases where the code for allowing group syntax
1459 while scanning a header line wasn't quite right (mostly, not resetting
1460 the flag correctly in the right place). These bugs could have caused
1461 trouble for malformed header lines. I hope it is now all correct.

PH
1463PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1465 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1466 but it didn't always do it. This confused somebody who was copying the
1467 code for some other use. I have removed all the tests.

PH
1469PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1470 feature that was used to support insecure browsers during the U.S. crypto
1471 embargo. It requires special client support, and Exim is probably the
1472 only MTA that supported it -- and would never use it because real RSA is
1473 always available. This code has been removed, because it had the bad
1474 effect of slowing Exim down by computing (never used) parameters for the
1475 RSA_EXPORT functionality.

1481 if the connection is using TLS or if the remote IP is the same as the
1482 local IP, and the "valid-client-cert option" if a client certificate has

1514
1515PH/30 Exim was sometimes attempting to deliver messages that had suffered
1516 address errors (4xx response to RCPT) over the same connection as other
1517 messages routed to the same hosts. Such deliveries are always "forced",
1518 so retry times are not inspected. This resulted in far too many retries
1519 for the affected addresses. The effect occurred only when there were more
1520 hosts than the hosts_max_try setting in the smtp transport when it had
1521 the 4xx errors. Those hosts that it had tried were not added to the list
1522 of hosts for which the message was waiting, so if all were tried, there
1523 was no problem. Two fixes have been applied:
1524
1525 (i) If there are any address or message errors in an SMTP delivery, none
1526 of the hosts (tried or untried) are now added to the list of hosts
1527 for which the message is waiting, so the message should not be a
1528 candidate for sending over the same connection that was used for a
1529 successful delivery of some other message. This seems entirely
1530 reasonable: after all the message is NOT "waiting for some host".
1531 This is so "obvious" that I'm not sure why it wasn't done
1532 previously. Hope I haven't missed anything, but it can't do any
1533 harm, as the worst effect is to miss an optimization.
1534
1535 (ii) If, despite (i), such a delivery is accidentally attempted, the
1536 routing retry time is respected, so at least it doesn't keep
1537 hammering the server.

1552PH/35 The error "getsockname() failed: connection reset by peer" was being
1553 written to the panic log as well as the main log, but it isn't really

1555 removed the panic log writing for the ECONNRESET error when getsockname()
1556 fails.

48c7f9e2
PH
1558PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1559 runs only) independently of the message's sender address. This meant
1560 that, if the 4xx error was in fact related to the sender, a different
1561 message to the same recipient with a different sender could confuse
1562 things. In particualar, this can happen when sending to a greylisting
1563 server, but other circumstances could also provoke similar problems.
1564 I have changed the default so that the retry time for these errors is now
1565 based a combination of the sender and recipient addresses. This change
1566 can be overridden by setting address_retry_include_sender=false in the
1567 smtp transport.

1835PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1838 tcp-wrappers gives "deny", whereas what one would like would be some
1839 kind of temporary error. A kludge has been added to help with this.
1840 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1841 554 error is used if errno is still zero or contains ENOENT (which occurs
1842 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1883 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

1928 autoreply, Exim could try to deliver to a non-existent relative file

1964 Instead, it always explicitly searches for A/AAAA records. This avoids
1965 major problems that occur when a DNS server includes only records of one
1966 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has

1979PH/19 When calculating a retry time, Exim used to measure the "time since
1980 failure" by looking at the "first failed" field in the retry record. Now
1981 it does not use this if it is later than than the arrival time of the
1982 message. Instead it uses the arrival time. This makes for better
1983 behaviour in cases where some deliveries succeed, thus re-setting the
1984 "first failed" field. An example is a quota failure for a huge message
1985 when small messages continue to be delivered. Without this change, the
1986 "time since failure" will always be short, possible causing more frequent
1987 delivery attempts for the huge message than are intended.

2084PH/42 The content-scanning code uses fopen() to create files in which to put
2085 message data. Previously it was not paying any attention to the mode of
2086 the files. Exim runs with umask(0) because the rest of the code creates
2087 files with open(), and sets the required mode explicitly. Thus, these
2088 files were ending up world-writeable. This was not a big issue, because,
2089 being within the spool directory, they were not world-accessible. I have
2090 created a function called modefopen, which takes an additional mode
2091 argument. It sets umask(777), creates the file, chmods it to the required
2092 mode, then resets the umask. All the relevant calls to fopen() in the

2130
2131 (i) Exim was not creating retry information for temporary errors given
2132 for individual recipients after the DATA command when the smtp transport
2133 was used in LMTP mode. This meant that they could be retried too
2134 frequently, and not timed out correctly.
2135
2136 (ii) Exim was setting the flag that allows error details to be returned
2137 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2138 recipients that were returned after the DATA command.
2139
2140PH/53 This is related to PH/52, but is more general: for any failing address,
2141 when detailed error information was permitted to be returned to the
2142 sender, but the error was temporary, then after the final timeout, only
2143 "retry timeout exceeded" was returned. Now it returns the full error as

2214PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2215 function verify_get_ident() calls ip_connect() to connect a socket, but
2216 if the "connect()" function timed out, ip_connect() used to close the
2217 socket. However, verify_get_ident() also closes the socket later, and in
2218 between Exim writes to the log, which may get opened at this point. When
2219 the socket was closed in ip_connect(), the log could get the same file
2220 descriptor number as the socket. This naturally causes chaos. The fix is
2221 not to close the socket in ip_connect(); the socket should be closed by
2222 the function that creates it. There was only one place in the code where
2223 this was missing, in the iplookup router, which I don't think anybody now
2224 uses, but I've fixed it anyway.

2285
2286 Received: from [1.2.3.4] (helo=[1.2.3.4])

PH
2379PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2380 canonical form (as documented). However, after a host name lookup from
2381 the IP address, check_host() was doing a simple string comparison with
2382 addresses acquired from the DNS when checking that the found name did
2383 have the original IP as one of its addresses. Since any found IPv6
2384 addresses are likely to be in abbreviated form, the comparison could
2385 fail. Luckily, there already exists a function for doing the comparison
2386 by converting both addresses to binary, so now that is used instead of
2387 the text comparison.

PH
2389PH/20 There was another similar case to PH/19, when a complete host name was
2390 given in a host list; looking up its IP address could give an abbreviated
2391 form, whereas the current host's name might or might not be abbreviated.
2392 The same fix has been applied.

2771 the logs files are, rather than using the compiled in default. In our
2772 case the guess is not the same as the compiled default, so the script
2773 suddenly stopped working when I started to use syslog. The patch checks
2774 to see if log_file_path is "". If so, it attempts to read it from exim

2776 falls back to the previous guessing code."

2905PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2906 that changes the way the GnuTLS parameters are stored in the cache file.
2907 The new format can be generated externally. For backward compatibility,
2908 if the data in the cache doesn't make sense, Exim assumes it has read an
2909 old-format file, and it generates new data and writes a new file. This
2910 means that you can't go back to an older release without removing the
2911 file.
2912
2913PH/03 A redirect router that has both "unseen" and "one_time" set does not
2914 work if there are any delivery delays because "one_time" forces the
2915 parent to be marked "delivered", so its unseen clone is never tried
2916 again. For this reason, Exim now forbids the simultaneous setting of
2917 these two options.

2922 consider the case when local delivery batching is involved. The test for
2923 "previously delivered" was not happening when checking to see if an
2924 address could be batched with a previous (undelivered) one; under
2925 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2926 address.

2931PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

2933 In particular, this caused confusion with an attempt to use "verify =
2934 reverse_host_lookup/defer_ok". An error is now given when options are
2935 supplied for verify items that do not have them. (Maybe reverse_host_

2991 the file with the wrong ownership). There was no test for failure of this
2992 fork() call, which would lead to the process getting stuck as it waited

3001 string after "input=" when read() returned zero. If read() returned -1

3014PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3015 hadn't been configured. The fix is from Juergen Kreileder, who
3016 understands it better than I do:
3017
3018 "Here's what I see happening with three configured cyrus_sasl
3019 authenticators configured (plain, login, cram-md5):
3020
3021 On startup auth_cyrus_sasl_init() gets called for each of these.
3022 This means three calls to sasl_listmech() without a specified mech_list.
3023 => SASL tests which mechs of all available mechs actually work
3024 => three warnings about OTP not working
3025 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3026
3027 With the patch, sasl_listmech() also gets called three times. But now
3028 SASL's mech_list option is set to the server_mech specified in the the
3029 authenticator. Or in other words, the answer from sasl_listmech()
3030 gets limited to just the mech you're testing for (which is different
3031 for each call.)
3032 => the return list contains just 'plain' or 'login', 'cram-md5' or
3033 nothing depending on the value of ob->server_mech.
3034
3035 I've just tested the patch: Authentication still works fine,
3036 unavailable mechs specified in the exim configuration are still

PH
3101PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3102 the grounds that routing the same address twice would always produce the
3103 same answer. This might have been true once, but it is certainly no
3104 longer true now. Routing a child address may depend on the previous
3105 routing that produced that child. Some complicated redirection strategies
3106 went wrong when messages had multiple recipients, and made Exim's
3107 behaviour dependent on the order in which the addresses were given.
3108
3109 I have moved the duplicate checking until after the routing is complete.
3110 Exim scans the addresses that are assigned to local and remote
3111 transports, and removes any duplicates. This means that more work will be
3112 done, as duplicates will always all be routed, but duplicates are
3113 presumably rare, so I don't expect this is of any significance.
3114
3115 For deliveries to pipes, files, and autoreplies, the duplicate checking
3116 still happens during the routing process, since they are not going to be
3117 routed further.

3163 treated as errors, giving rise to delivery failures by default. However,
3164 there is now a new Boolean option for the pipe transport called
3165 timeout_defer, which, if set TRUE, converts the failures into defers for
3166 both kinds of timeout. A transport filter timeout is now identified in
3167 the log output.

3169PH/46 The "scripts/Configure-config.h" script calls "make" at one point. On
3170 systems where "make" and "gmake" are different, calling "gmake" at top
3171 level broke things. I've arranged for the value of $(MAKE) to be passed
3172 from the Makefile to this script so that it can call the same version of
3173 "make".

3176A note about Exim versions 4.44 and 4.50
3177----------------------------------------
3178
3179Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3180changes of various kinds. As a consequence, a big documentation update was
3181needed. This delayed the release for rather longer than seemed good, especially
3182in the light of a couple of (minor) security issues. Therefore, the changes
3183that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3184release. So 4.44 and 4.50 are in effect two different branches that both start
3185from 4.43.
3186
3187I have left the 4.50 change log unchanged; it contains all the changes since
31884.43. The change log for 4.44 is below; many of its items are identical to
3189those for 4.50. This seems to be the most sensible way to preserve the
3190historical information.

PH
3196 1. Minor wording change to the doc/README.SIEVE file.
3197
139059f6 3198 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 3199 computation of the current number of files was incorrect.

PH
3201 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3202 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3203 place.
3204
35af9f61
PH
3205 4. Give more explanation in the error message when the command for a transport
3206 filter fails to execute.
3207
b668c215
PH
3208 5. There are several places where Exim runs a non-Exim command in a
3209 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3210 was being done only for the command run by the queryprogram router. It is
3211 now done for all such subprocesses. The other cases are: ${run, transport
3212 filters, and the commands run by the lmtp and pipe transports.
3213
a494b1e1
PH
3214 6. Added CONFIGURE_GROUP build-time option.
3215
3216 7. Some older OS have a limit of 256 on the maximum number of file
3217 descriptors. Exim was using setrlimit() to set 1000 as a large value
3218 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3219 systems. I've change it so that if it can't get 1000, it tries for 256.

PH
3221 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3222 was an oversight, and furthermore, ever since the addition of extra
3223 controls (e.g. 4.43/32), the checks on when to allow different forms of
3224 "control" were broken. There should now be diagnostics for all cases when a
3225 control that does not make sense is encountered.
3226
69358f02
PH
3227 9. Added the /retain_sender option to "control=submission".

PH
322910. $recipients is now available in the predata ACL (oversight).

PH
323111. Tidy the search cache before the fork to do a delivery from a message
3232 received from the command line. Otherwise the child will trigger a lookup
3233 failure and thereby defer the delivery if it tries to use (for example) a
3234 cached ldap connection that the parent has called unbind on.
3235
2a3eea10
PH
323612. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3237 of $address_data from the recipient verification was clobbered by the
3238 sender verification.
3239
324013. The value of address_data from a sender verification is now available in
3241 $sender_address_data in subsequent conditions in the ACL statement.
3242
23c7ff99
PH
324314. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3244
4deaf07d
PH
324515. Added a new option "connect=<time>" to callout options, to set a different
3246 connection timeout.
3247
926e1192
PH
324816. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3249 was its contents. (It was OK if the option was not defined at all.)
3250
650edc6f
PH
325117. A "Completed" log line is now written for messages that are removed from
3252 the spool by the -Mrm option.
3253

PH
325418. New variables $sender_verify_failure and $recipient_verify_failure contain
3255 information about exactly what failed.

PH
325719. Added -dd to debug only the daemon process.

7c7ad977
PH
325920. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3260 handles timeouts, both on the server side and network timeouts. Renamed the
3261 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3262

PH
326321. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3264 It is now set to "smtps".

d4eb88df
PH
326622. $host_address is now set to the target address during the checking of
3267 ignore_target_hosts.
3268
326923. When checking ignore_target_hosts for an ipliteral router, no host name was
3270 being passed; this would have caused $sender_host_name to have been used if
3271 matching the list had actually called for a host name (not very likely,
3272 since this list is usually IP addresses). A host name is now passed as
3273 "[x.x.x.x]".
3274
7d468ab8
PH
327524. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3276 code that specifies a non-restarting handler (typically sigaction() in
3277 modern systems) in an attempt to fix a rare and obscure crash bug.
3278
327925. Narrowed the window for a race in the daemon that could cause it to ignore
3280 SIGCHLD signals. This is not a major problem, because they are used only to
3281 wake it up if nothing else does.
3282
62c0818f
PH
328326. A malformed maildirsize file could cause Exim to calculate negative values
3284 for the mailbox size or file count. Odd effects could occur as a result.
3285 The maildirsize information is now recalculated if the size or filecount
3286 end up negative.
3287
26034054
PH
328827. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3289 support for a long time. Removed HAVE_SYS_VFS_H.

af66f652
PH
329128. Installed the latest version of exipick from John Jetmore.
3292
90af77f4
PH
329329. In an address list, if the pattern was not a regular expression, an empty
3294 subject address (from a bounce message) matched only if the pattern was an
3295 empty string. Non-empty patterns were not even tested. This was the wrong
3296 because it is perfectly reasonable to use an empty address as part of a
3297 database query. An empty address is now tested by patterns that are
3298 lookups. However, all the other forms of pattern expect the subject to
3299 contain a local part and a domain, and therefore, for them, an empty
3300 address still always fails if the pattern is not itself empty.
3301
d8ef3577
PH
330230. Exim went into a mad DNS loop when attempting to do a callout where the
3303 host was specified on an smtp transport, and looking it up yielded more
3304 than one IP address.
3305
5cb8cbc6
PH
330631. Re-factored the code for checking spool and log partition space into a
3307 function that finds that data and another that does the check. The former
3308 is then used to implement four new variables: $spool_space, $log_space,
3309 $spool_inodes, and $log_inodes.
3310
14702f5b
PH
331132. The RFC2047 encoding function was originally intended for short strings
3312 such as real names; it was not keeping to the 75-character limit for
3313 encoded words that the RFC imposes. It now respects the limit, and
3314 generates multiple encoded words if necessary. To be on the safe side, I
3315 have increased the buffer size for the ${rfc2047: expansion operator from
3316 1024 to 2048 bytes.
3317
063b1e99
PH
331833. It is now permitted to omit both strings after an "if" condition; if the
3319 condition is true, the result is "true". As before, when the second string
3320 is omitted, a false condition yields an empty string. This makes it less
3321 cumbersome to write custom ACL and router conditions.
3322
652e1b65
PH
332334. Failure to deliver a bounce message always caused it to be frozen, even if
3324 there was an errors_to setting on the router. The errors_to setting is now
3325 respected.
3326
6f0c9a4f
PH
332735. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3328 canonical form (fully expanded) before being placed in
3329 $sender_host_address.
3330
33397d19
PH
333136. The table in the code that translates DNS record types into text (T_A to
3332 "A" for instance) was missing entries for NS and CNAME. It is just possible
3333 that this could have caused confusion if both these types were looked up
3334 for the same domain, because the text type is used as part of Exim's
3335 per-process caching. But the chance of anyone hitting this buglet seems
3336 very small.
3337
7bb56e1f
PH
333837. The dnsdb lookup has been extended in a number of ways.
3339
3340 (1) There is a new type, "zns", which walks up the domain tree until it
3341 finds some nameserver records. It should be used with care.
3342
ea3bc19b
PH
3343 (2) There is a new type, "mxh", which is like "mx" except that it returns
3344 just the host names, not the priorities.
3345
3346 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3347 looked up. The behaviour when one of the lookups defers can be
3348 controlled by a keyword.
7bb56e1f 3349
ea3bc19b 3350 (4) It is now possible to specify the separator character for use when
7bb56e1f 3351 multiple records are returned.
33397d19 3352
0bcb2a0e
PH
335338. The dnslists ACL condition has been extended: it is now possible to supply
3354 a list of IP addresses and/or domains to be looked up in a particular DNS
3355 domain.
3356
2ac0e484
PH
335739. Added log_selector=+queue_time_overall.
3358
4e1fde53
PH
335940. When running the queue in the test harness, wait just a tad after forking a
3360 delivery process, to get repeatability of debugging output.
3361
de365ded
PH
336241. Include certificate and key file names in error message when GnuTLS fails
3363 to set them up, because the GnuTLS error message doesn't include the name
3364 of the failing file when there is a problem reading it.
3365
f05da2e8
PH
336642. Allow both -bf and -bF in the same test run.

PH
337044. The "Exiscan patch" is now merged into the mainline Exim source.
3371
337245. Sometimes the final signoff response after QUIT could fail to get
3373 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3374 < 0 before doing a fflush(). This bug looks as though it goes back to the
3375 introduction of TLS in release 3.20, but "sometimes" must have been rare
3376 because the tests only now provoked it.
3377

337846. Reset the locale to "C" after calling embedded Perl, in case it was changed
3379 (this can affect the format of dates).

PH
338147. exim_tidydb, when checking for the continued existence of a message for
3382 which it has found a message-specific retry record, was not finding
3383 messages that were in split spool directories. Consequently, it was
