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

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

TF
339TF/03 Make the exiwhat support code safe for signals. Previously Exim might
340 lock up or crash if it happened to be inside a call to libc when it
341 got a SIGUSR1 from exiwhat.
342
343 The SIGUSR1 handler appends the current process status to the process
344 log which is later printed by exiwhat. It used to use the general
345 purpose logging code to do this, but several functions it calls are
346 not safe for signals.
347
348 The new output code in the SIGUSR1 handler is specific to the process
349 log, and simple enough that it's easy to inspect for signal safety.
350 Removing some special cases also simplifies the general logging code.
351 Removing the spurious timestamps from the process log simplifies
352 exiwhat.
353
c99ce5c9
TF
354TF/04 Improved ratelimit ACL condition.
355
356 The /noupdate option has been deprecated in favour of /readonly which
357 has clearer semantics. The /leaky, /strict, and /readonly update modes
358 are mutually exclusive. The update mode is no longer included in the
359 database key; it just determines when the database is updated. (This
360 means that when you upgrde Exim will forget old rate measurements.)
361
362 Exim now checks that the per_* options are used with an update mode that
363 makes sense for the current ACL. For example, when Exim is processing a
364 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
365 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
366 must specify per_mail/readonly. If you omit the update mode it defaults to
367 /leaky where that makes sense (as before) or /readonly where required.
368
369 The /noupdate option is now undocumented but still supported for
370 backwards compatibility. It is equivalent to /readonly except that in
371 ACLs where /readonly is required you may specify /leaky/noupdate or
372 /strict/noupdate which are treated the same as /readonly.
373
374 A useful new feature is the /count= option. This is a generalization
375 of the per_byte option, so that you can measure the throughput of other
376 aggregate values. For example, the per_byte option is now equivalent
377 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
378
379 The per_rcpt option has been generalized using the /count= mechanism
380 (though it's more complicated than the per_byte equivalence). When it is
381 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
382 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
383 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
384 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
385 Note that using per_rcpt with a non-readonly update mode in more than
386 one ACL will cause the recipients to be double-counted. (The per_mail
387 and per_byte options don't have this problem.)
388
389 The handling of very low rates has changed slightly. If the computed rate
390 is less than the event's count (usually one) then this event is the first
391 after a long gap. In this case the rate is set to the same as this event's
392 count, so that the first message of a spam run is counted properly.
393
394 The major new feature is a mechanism for counting the rate of unique
395 events. The new per_addr option counts the number of different
396 recipients that someone has sent messages to in the last time period. It
397 behaves like per_rcpt if all the recipient addresses are different, but
398 duplicate recipient addresses do not increase the measured rate. Like
399 the /count= option this is a general mechanism, so the per_addr option
400 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
401 example, measure the rate that a client uses different sender addresses
402 with the options per_mail/unique=$sender_address. There are further
403 details in the main documentation.

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

974
975PH/01 Another patch from the Sieve maintainer.
976
6a3bceb1
PH
977PH/02 When an IPv6 address is converted to a string for single-key lookup
978 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
979 dots are used instead of colons so that keys in lsearch files need not
980 contain colons. This was done some time before quoting was made available
981 in lsearch files. However, iplsearch files do require colons in IPv6 keys
982 (notated using the quote facility) so as to distinguish them from IPv4
983 keys. This meant that lookups for IP addresses in host lists did not work
984 for iplsearch lookups.
985
986 This has been fixed by arranging for IPv6 addresses to be expressed with
987 colons if the lookup type is iplsearch. This is not incompatible, because
988 previously such lookups could never work.
989
990 The situation is now rather anomolous, since one *can* have colons in
991 ordinary lsearch keys. However, making the change in all cases is
992 incompatible and would probably break a number of configurations.

997MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
998 conversion specification without a maximum field width, thereby enabling
999 a rogue spamd server to cause a buffer overflow. While nobody in their
1000 right mind would setup Exim to query an untrusted spamd server, an
1001 attacker that gains access to a server running spamd could potentially
1002 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1007MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1008 a directory entry by the name of the lookup key. Previously, if a
1009 symlink pointed to a non-existing file or a file in a directory that
1010 Exim lacked permissions to read, a lookup for a key matching that
1011 symlink would fail. Now it is enough that a matching directory entry
1012 exists, symlink or not. (Bugzilla 503.)

1197 any. However, for some commands, a delay in an ACL can mean that it is
1198 some time before the response is written. In this time, more input might
1199 arrive, invalidly. So now there are extra checks after an ACL has run for
1200 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1201 pipelining has not been advertised.

1216 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1217 was a macro that became an assignment, so it seemed to work. This has
1218 changed to a proper function call with a void return, hence the compile

1275 the response to the final '.' that terminates a message, but only in the
1276 case where the client has not sent further data following the '.'
1277 (unfortunately, this is allowed). However, in many cases there won't be
1278 any further data because there won't be any more messages to send. A call
1279 to select() can be used: if it shows that the input is "ready", there is
1280 either input waiting, or the socket has been closed. An attempt to read
1281 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1282 would have sent an OK response which the client would never have see.

1293PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1294 fixed by 4.65/MH/01 (is this a record?) are fixed:
1295
1296 (i) An empty string was always treated as zero by the numeric comparison
1297 operators. This behaviour has been restored.
1298
1299 (ii) It is documented that the numeric comparison operators always treat
1300 their arguments as decimal numbers. This was broken in that numbers
1301 starting with 0 were being interpreted as octal.
1302
1303 While fixing these problems I realized that there was another issue that
1304 hadn't been noticed. Values of message_size_limit (both the global option
1305 and the transport option) were treated as octal if they started with 0.
1306 The documentation was vague. These values are now always treated as
1307 decimal, and I will make that clear in the documentation.

1324 large number of recipients for a single message is ridiculous

PH
1351PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1352 callout verification, Exim cached a "reject" for the entire domain. This
1353 is correct for most verifications, but it is not correct for a recipient
1354 verification with use_sender or use_postmaster set, because in that case
1355 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1356 case of MAIL FROM:<> rejection from other early rejections (e.g.
1357 rejection of HELO). When verifying a recipient using a non-null MAIL
1358 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1359 Whatever the result of the callout, the value of the domain cache is
1360 left unchanged (for any other kind of callout, getting as far as trying
1361 RCPT means that the domain itself is ok).

1397 probably the interface on which it is arriving) and not to the outgoing
1398 callout (which could be using a different interface). This has been
1399 changed to use the value of the helo_data option from the smtp transport
1400 instead - this is what is used when a message is actually being sent. If
1401 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
1406 (a) The code assumed that strncpy() returns a negative number on buffer
1407 overflow, which isn't the case. Replaced with Exim's string_format()
1408 function.
1409 (b) There were several signed/unsigned issues. I just did the minimum
1410 hacking in of casts. There is scope for a larger refactoring.
1411 (c) The code used strcasecmp() which is not a standard C function.
1412 Replaced with Exim's strcmpic() function.
1413 (d) The code set only $1; it now sets $auth1 as well.
1414 (e) A simple test gave the error "authentication client didn't specify
1415 service in request". It would seem that Dovecot has changed its
1416 interface. Fortunately there's a specification; I followed it and
1417 changed what the client sends and it appears to be working now.

1424 -v the output is "A verified" because verification stops after a
1425 successful redirection if more than one address is generated. However,
1426 with -v the child addresses are also verified. Exim was outputting "A
1427 failed to verify" and then showing the successful verification for C,
1428 with its parentage. It now outputs "B failed to verify", showing B's
1429 parentage before showing the successful verification of C.

PH
1435PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1436 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1437 they consult the DNS. I had assumed they would set it the way they
1438 wanted; and indeed my experiments on Linux seem to show that in some
1439 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1440 To be on the safe side, however, I have now made the interface to
1441 host_find_byname() similar to host_find_bydns(), with an argument
1442 containing the DNS resolver options. The host_find_byname() function now
1443 sets these options at its start, just as host_find_bydns() does. The smtp
1444 transport options dns_qualify_single and dns_search_parents are passed to
1445 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1446 of host_find_byname() use the default settings of RES_DEFNAMES
1447 (qualify_single) but not RES_DNSRCH (search_parents).

1450 spool_read_header() do less string testing, by means of a preliminary
1451 switch on the second character of optional "-foo" lines. (This is
1452 overdue, caused by the large number of possibilities that now exist.
1453 Originally there were few.) While I was there, I also converted the
1454 str(n)cmp tests so they don't re-test the leading "-" and the first
1455 character, in the hope this might squeeze out yet more improvement.

1457PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1458 flag allowing group syntax was set by the header_syntax check but not
1459 turned off, possible causing trouble later; (2) The flag was not being
1460 set at all for the header_verify test, causing "group"-style headers to
1461 be rejected. I have now set it in this case, and also caused header_
1462 verify to ignore an empty address taken from a group. While doing this, I
1463 came across some other cases where the code for allowing group syntax
1464 while scanning a header line wasn't quite right (mostly, not resetting
1465 the flag correctly in the right place). These bugs could have caused
1466 trouble for malformed header lines. I hope it is now all correct.

1468PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

PH
1474PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1475 feature that was used to support insecure browsers during the U.S. crypto
1476 embargo. It requires special client support, and Exim is probably the
1477 only MTA that supported it -- and would never use it because real RSA is
1478 always available. This code has been removed, because it had the bad
1479 effect of slowing Exim down by computing (never used) parameters for the
1480 RSA_EXPORT functionality.

1487 local IP, and the "valid-client-cert option" if a client certificate has

1519
1520PH/30 Exim was sometimes attempting to deliver messages that had suffered
1521 address errors (4xx response to RCPT) over the same connection as other
1522 messages routed to the same hosts. Such deliveries are always "forced",
1523 so retry times are not inspected. This resulted in far too many retries
1524 for the affected addresses. The effect occurred only when there were more
1525 hosts than the hosts_max_try setting in the smtp transport when it had
1526 the 4xx errors. Those hosts that it had tried were not added to the list
1527 of hosts for which the message was waiting, so if all were tried, there
1528 was no problem. Two fixes have been applied:
1529
1530 (i) If there are any address or message errors in an SMTP delivery, none
1531 of the hosts (tried or untried) are now added to the list of hosts
1532 for which the message is waiting, so the message should not be a
1533 candidate for sending over the same connection that was used for a
1534 successful delivery of some other message. This seems entirely
1535 reasonable: after all the message is NOT "waiting for some host".
1536 This is so "obvious" that I'm not sure why it wasn't done
1537 previously. Hope I haven't missed anything, but it can't do any
1538 harm, as the worst effect is to miss an optimization.
1539
1540 (ii) If, despite (i), such a delivery is accidentally attempted, the
1541 routing retry time is respected, so at least it doesn't keep
1542 hammering the server.

1557PH/35 The error "getsockname() failed: connection reset by peer" was being
1558 written to the panic log as well as the main log, but it isn't really

1560 removed the panic log writing for the ECONNRESET error when getsockname()
1561 fails.

48c7f9e2
PH
1563PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1564 runs only) independently of the message's sender address. This meant
1565 that, if the 4xx error was in fact related to the sender, a different
1566 message to the same recipient with a different sender could confuse
1567 things. In particualar, this can happen when sending to a greylisting
1568 server, but other circumstances could also provoke similar problems.
1569 I have changed the default so that the retry time for these errors is now
1570 based a combination of the sender and recipient addresses. This change
1571 can be overridden by setting address_retry_include_sender=false in the
1572 smtp transport.

1840PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1843 tcp-wrappers gives "deny", whereas what one would like would be some
1844 kind of temporary error. A kludge has been added to help with this.
1845 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1846 554 error is used if errno is still zero or contains ENOENT (which occurs
1847 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1887 code found IPv4 interfaces correctly, but gave incorrect values for the
1888 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

1890 addresses as local.

1933 autoreply, Exim could try to deliver to a non-existent relative file

1967PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
1968 additional section of a DNS packet that returns MX or SRV records.
1969 Instead, it always explicitly searches for A/AAAA records. This avoids
1970 major problems that occur when a DNS server includes only records of one
1971 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has

1984PH/19 When calculating a retry time, Exim used to measure the "time since
1985 failure" by looking at the "first failed" field in the retry record. Now
1986 it does not use this if it is later than than the arrival time of the
1987 message. Instead it uses the arrival time. This makes for better
1988 behaviour in cases where some deliveries succeed, thus re-setting the
1989 "first failed" field. An example is a quota failure for a huge message
1990 when small messages continue to be delivered. Without this change, the
1991 "time since failure" will always be short, possible causing more frequent
1992 delivery attempts for the huge message than are intended.

2089PH/42 The content-scanning code uses fopen() to create files in which to put
2090 message data. Previously it was not paying any attention to the mode of
2091 the files. Exim runs with umask(0) because the rest of the code creates
2092 files with open(), and sets the required mode explicitly. Thus, these
2093 files were ending up world-writeable. This was not a big issue, because,
2094 being within the spool directory, they were not world-accessible. I have
2095 created a function called modefopen, which takes an additional mode
2096 argument. It sets umask(777), creates the file, chmods it to the required
2097 mode, then resets the umask. All the relevant calls to fopen() in the

2135
2136 (i) Exim was not creating retry information for temporary errors given
2137 for individual recipients after the DATA command when the smtp transport
2138 was used in LMTP mode. This meant that they could be retried too
2139 frequently, and not timed out correctly.
2140
2141 (ii) Exim was setting the flag that allows error details to be returned
2142 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2143 recipients that were returned after the DATA command.
2144
2145PH/53 This is related to PH/52, but is more general: for any failing address,
2146 when detailed error information was permitted to be returned to the
2147 sender, but the error was temporary, then after the final timeout, only
2148 "retry timeout exceeded" was returned. Now it returns the full error as

2219PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2220 function verify_get_ident() calls ip_connect() to connect a socket, but
2221 if the "connect()" function timed out, ip_connect() used to close the
2222 socket. However, verify_get_ident() also closes the socket later, and in
2223 between Exim writes to the log, which may get opened at this point. When
2224 the socket was closed in ip_connect(), the log could get the same file
2225 descriptor number as the socket. This naturally causes chaos. The fix is
2226 not to close the socket in ip_connect(); the socket should be closed by
2227 the function that creates it. There was only one place in the code where
2228 this was missing, in the iplookup router, which I don't think anybody now
2229 uses, but I've fixed it anyway.

2291 Received: from [1.2.3.4] (helo=[1.2.3.4])

PH
2384PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2385 canonical form (as documented). However, after a host name lookup from
2386 the IP address, check_host() was doing a simple string comparison with
2387 addresses acquired from the DNS when checking that the found name did
2388 have the original IP as one of its addresses. Since any found IPv6
2389 addresses are likely to be in abbreviated form, the comparison could
2390 fail. Luckily, there already exists a function for doing the comparison
2391 by converting both addresses to binary, so now that is used instead of
2392 the text comparison.
2393

PH
2394PH/20 There was another similar case to PH/19, when a complete host name was
2395 given in a host list; looking up its IP address could give an abbreviated
2396 form, whereas the current host's name might or might not be abbreviated.
2397 The same fix has been applied.

2776 the logs files are, rather than using the compiled in default. In our
2777 case the guess is not the same as the compiled default, so the script
2778 suddenly stopped working when I started to use syslog. The patch checks
2779 to see if log_file_path is "". If so, it attempts to read it from exim

2781 falls back to the previous guessing code."

2910PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2911 that changes the way the GnuTLS parameters are stored in the cache file.
2912 The new format can be generated externally. For backward compatibility,
2913 if the data in the cache doesn't make sense, Exim assumes it has read an
2914 old-format file, and it generates new data and writes a new file. This
2915 means that you can't go back to an older release without removing the
2916 file.
2917
2918PH/03 A redirect router that has both "unseen" and "one_time" set does not
2919 work if there are any delivery delays because "one_time" forces the
2920 parent to be marked "delivered", so its unseen clone is never tried
2921 again. For this reason, Exim now forbids the simultaneous setting of
2922 these two options.

2927 consider the case when local delivery batching is involved. The test for
2928 "previously delivered" was not happening when checking to see if an
2929 address could be batched with a previous (undelivered) one; under
2930 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2931 address.

2936PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

2938 In particular, this caused confusion with an attempt to use "verify =
2939 reverse_host_lookup/defer_ok". An error is now given when options are
2940 supplied for verify items that do not have them. (Maybe reverse_host_

2996 the file with the wrong ownership). There was no test for failure of this
2997 fork() call, which would lead to the process getting stuck as it waited

3019PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it

3021 understands it better than I do:
3022
3023 "Here's what I see happening with three configured cyrus_sasl
3024 authenticators configured (plain, login, cram-md5):
3025
3026 On startup auth_cyrus_sasl_init() gets called for each of these.
3027 This means three calls to sasl_listmech() without a specified mech_list.
3028 => SASL tests which mechs of all available mechs actually work
3029 => three warnings about OTP not working
3030 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3031
3032 With the patch, sasl_listmech() also gets called three times. But now
3033 SASL's mech_list option is set to the server_mech specified in the the
3034 authenticator. Or in other words, the answer from sasl_listmech()
3035 gets limited to just the mech you're testing for (which is different
3036 for each call.)
3037 => the return list contains just 'plain' or 'login', 'cram-md5' or
3038 nothing depending on the value of ob->server_mech.
3039

PH
3106PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3107 the grounds that routing the same address twice would always produce the
3108 same answer. This might have been true once, but it is certainly no
3109 longer true now. Routing a child address may depend on the previous
3110 routing that produced that child. Some complicated redirection strategies
3111 went wrong when messages had multiple recipients, and made Exim's
3112 behaviour dependent on the order in which the addresses were given.
3113
3114 I have moved the duplicate checking until after the routing is complete.
3115 Exim scans the addresses that are assigned to local and remote
3116 transports, and removes any duplicates. This means that more work will be
3117 done, as duplicates will always all be routed, but duplicates are
3118 presumably rare, so I don't expect this is of any significance.
3119
3120 For deliveries to pipes, files, and autoreplies, the duplicate checking
3121 still happens during the routing process, since they are not going to be
3122 routed further.

3168 treated as errors, giving rise to delivery failures by default. However,
3169 there is now a new Boolean option for the pipe transport called
3170 timeout_defer, which, if set TRUE, converts the failures into defers for
3171 both kinds of timeout. A transport filter timeout is now identified in
3172 the log output.

3174PH/46 The "scripts/Configure-config.h" script calls "make" at one point. On
3175 systems where "make" and "gmake" are different, calling "gmake" at top
3176 level broke things. I've arranged for the value of $(MAKE) to be passed
3177 from the Makefile to this script so that it can call the same version of
3178 "make".

3181A note about Exim versions 4.44 and 4.50
3182----------------------------------------
3183
3184Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3185changes of various kinds. As a consequence, a big documentation update was
3186needed. This delayed the release for rather longer than seemed good, especially
3187in the light of a couple of (minor) security issues. Therefore, the changes
3188that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3189release. So 4.44 and 4.50 are in effect two different branches that both start
3190from 4.43.
3191
3192I have left the 4.50 change log unchanged; it contains all the changes since
31934.43. The change log for 4.44 is below; many of its items are identical to
3194those for 4.50. This seems to be the most sensible way to preserve the
3195historical information.

3201 1. Minor wording change to the doc/README.SIEVE file.
3202
139059f6 3203 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 3204 computation of the current number of files was incorrect.

PH
3206 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3207 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3208 place.
3209
35af9f61
PH
3210 4. Give more explanation in the error message when the command for a transport
3211 filter fails to execute.
3212
b668c215
PH
3213 5. There are several places where Exim runs a non-Exim command in a
3214 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3215 was being done only for the command run by the queryprogram router. It is
3216 now done for all such subprocesses. The other cases are: ${run, transport
3217 filters, and the commands run by the lmtp and pipe transports.
3218
a494b1e1
PH
3219 6. Added CONFIGURE_GROUP build-time option.
3220
3221 7. Some older OS have a limit of 256 on the maximum number of file
3222 descriptors. Exim was using setrlimit() to set 1000 as a large value
3223 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3224 systems. I've change it so that if it can't get 1000, it tries for 256.

3226 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3227 was an oversight, and furthermore, ever since the addition of extra
3228 controls (e.g. 4.43/32), the checks on when to allow different forms of
3229 "control" were broken. There should now be diagnostics for all cases when a
3230 control that does not make sense is encountered.
3231

PH
3232 9. Added the /retain_sender option to "control=submission".

PH
323611. Tidy the search cache before the fork to do a delivery from a message
3237 received from the command line. Otherwise the child will trigger a lookup
3238 failure and thereby defer the delivery if it tries to use (for example) a
3239 cached ldap connection that the parent has called unbind on.
3240

PH
324112. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3242 of $address_data from the recipient verification was clobbered by the
3243 sender verification.
3244
324513. The value of address_data from a sender verification is now available in
3246 $sender_address_data in subsequent conditions in the ACL statement.
3247

PH
324814. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.

PH
325015. Added a new option "connect=<time>" to callout options, to set a different
3251 connection timeout.
3252
926e1192
PH
325316. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3254 was its contents. (It was OK if the option was not defined at all.)
3255

PH
325617. A "Completed" log line is now written for messages that are removed from
3257 the spool by the -Mrm option.

325918. New variables $sender_verify_failure and $recipient_verify_failure contain
3260 information about exactly what failed.

PH
326420. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3265 handles timeouts, both on the server side and network timeouts. Renamed the
3266 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).

326821. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3269 It is now set to "smtps".

PH
327122. $host_address is now set to the target address during the checking of
3272 ignore_target_hosts.
3273
327423. When checking ignore_target_hosts for an ipliteral router, no host name was
3275 being passed; this would have caused $sender_host_name to have been used if
3276 matching the list had actually called for a host name (not very likely,
3277 since this list is usually IP addresses). A host name is now passed as
3278 "[x.x.x.x]".
3279
7d468ab8
PH
328024. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3281 code that specifies a non-restarting handler (typically sigaction() in
3282 modern systems) in an attempt to fix a rare and obscure crash bug.
3283
328425. Narrowed the window for a race in the daemon that could cause it to ignore
3285 SIGCHLD signals. This is not a major problem, because they are used only to
3286 wake it up if nothing else does.
3287
62c0818f
PH
328826. A malformed maildirsize file could cause Exim to calculate negative values
3289 for the mailbox size or file count. Odd effects could occur as a result.
3290 The maildirsize information is now recalculated if the size or filecount
3291 end up negative.
3292
26034054
PH
329327. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3294 support for a long time. Removed HAVE_SYS_VFS_H.

329628. Installed the latest version of exipick from John Jetmore.
3297
90af77f4
PH
329829. In an address list, if the pattern was not a regular expression, an empty
3299 subject address (from a bounce message) matched only if the pattern was an
3300 empty string. Non-empty patterns were not even tested. This was the wrong
3301 because it is perfectly reasonable to use an empty address as part of a
3302 database query. An empty address is now tested by patterns that are
3303 lookups. However, all the other forms of pattern expect the subject to
3304 contain a local part and a domain, and therefore, for them, an empty
3305 address still always fails if the pattern is not itself empty.
3306
d8ef3577
PH
330730. Exim went into a mad DNS loop when attempting to do a callout where the
3308 host was specified on an smtp transport, and looking it up yielded more
3309 than one IP address.
3310
5cb8cbc6
PH
331131. Re-factored the code for checking spool and log partition space into a
3312 function that finds that data and another that does the check. The former
3313 is then used to implement four new variables: $spool_space, $log_space,
3314 $spool_inodes, and $log_inodes.
3315

PH
331632. The RFC2047 encoding function was originally intended for short strings
3317 such as real names; it was not keeping to the 75-character limit for
3318 encoded words that the RFC imposes. It now respects the limit, and
3319 generates multiple encoded words if necessary. To be on the safe side, I
3320 have increased the buffer size for the ${rfc2047: expansion operator from
3321 1024 to 2048 bytes.
3322
063b1e99
PH
332333. It is now permitted to omit both strings after an "if" condition; if the
3324 condition is true, the result is "true". As before, when the second string
3325 is omitted, a false condition yields an empty string. This makes it less
3326 cumbersome to write custom ACL and router conditions.
3327
652e1b65
PH
332834. Failure to deliver a bounce message always caused it to be frozen, even if
3329 there was an errors_to setting on the router. The errors_to setting is now
3330 respected.
3331
6f0c9a4f
PH
333235. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3333 canonical form (fully expanded) before being placed in
3334 $sender_host_address.
3335
33397d19
PH
333636. The table in the code that translates DNS record types into text (T_A to
3337 "A" for instance) was missing entries for NS and CNAME. It is just possible
3338 that this could have caused confusion if both these types were looked up
3339 for the same domain, because the text type is used as part of Exim's
3340 per-process caching. But the chance of anyone hitting this buglet seems
3341 very small.
3342
7bb56e1f
PH
334337. The dnsdb lookup has been extended in a number of ways.
3344
3345 (1) There is a new type, "zns", which walks up the domain tree until it
3346 finds some nameserver records. It should be used with care.
3347
ea3bc19b
PH
3348 (2) There is a new type, "mxh", which is like "mx" except that it returns
3349 just the host names, not the priorities.
3350
3351 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3352 looked up. The behaviour when one of the lookups defers can be
3353 controlled by a keyword.
7bb56e1f 3354
ea3bc19b 3355 (4) It is now possible to specify the separator character for use when
7bb56e1f 3356 multiple records are returned.
33397d19 3357
0bcb2a0e
PH
335838. The dnslists ACL condition has been extended: it is now possible to supply
3359 a list of IP addresses and/or domains to be looked up in a particular DNS
3360 domain.

336239. Added log_selector=+queue_time_overall.

336440. When running the queue in the test harness, wait just a tad after forking a
3365 delivery process, to get repeatability of debugging output.

PH
336741. Include certificate and key file names in error message when GnuTLS fails
3368 to set them up, because the GnuTLS error message doesn't include the name
3369 of the failing file when there is a problem reading it.
3370

337544. The "Exiscan patch" is now merged into the mainline Exim source.
3376
337745. Sometimes the final signoff response after QUIT could fail to get
3378 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3379 < 0 before doing a fflush(). This bug looks as though it goes back to the
3380 introduction of TLS in release 3.20, but "sometimes" must have been rare
3381 because the tests only now provoked it.
