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
328TF/03 Make the exiwhat support code safe for signals. Previously Exim might
329 lock up or crash if it happened to be inside a call to libc when it
330 got a SIGUSR1 from exiwhat.
331
332 The SIGUSR1 handler appends the current process status to the process
333 log which is later printed by exiwhat. It used to use the general
334 purpose logging code to do this, but several functions it calls are
335 not safe for signals.
336
337 The new output code in the SIGUSR1 handler is specific to the process
338 log, and simple enough that it's easy to inspect for signal safety.
339 Removing some special cases also simplifies the general logging code.
340 Removing the spurious timestamps from the process log simplifies
341 exiwhat.
342
c99ce5c9
TF
343TF/04 Improved ratelimit ACL condition.
344
345 The /noupdate option has been deprecated in favour of /readonly which
346 has clearer semantics. The /leaky, /strict, and /readonly update modes
347 are mutually exclusive. The update mode is no longer included in the
348 database key; it just determines when the database is updated. (This
349 means that when you upgrde Exim will forget old rate measurements.)
350
351 Exim now checks that the per_* options are used with an update mode that
352 makes sense for the current ACL. For example, when Exim is processing a
353 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
354 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
355 must specify per_mail/readonly. If you omit the update mode it defaults to
356 /leaky where that makes sense (as before) or /readonly where required.
357
358 The /noupdate option is now undocumented but still supported for
359 backwards compatibility. It is equivalent to /readonly except that in
360 ACLs where /readonly is required you may specify /leaky/noupdate or
361 /strict/noupdate which are treated the same as /readonly.
362
363 A useful new feature is the /count= option. This is a generalization
364 of the per_byte option, so that you can measure the throughput of other
365 aggregate values. For example, the per_byte option is now equivalent
366 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
367
368 The per_rcpt option has been generalized using the /count= mechanism
369 (though it's more complicated than the per_byte equivalence). When it is
370 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
371 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
372 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
373 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
374 Note that using per_rcpt with a non-readonly update mode in more than
375 one ACL will cause the recipients to be double-counted. (The per_mail
376 and per_byte options don't have this problem.)
377
378 The handling of very low rates has changed slightly. If the computed rate
379 is less than the event's count (usually one) then this event is the first
380 after a long gap. In this case the rate is set to the same as this event's
381 count, so that the first message of a spam run is counted properly.
382
383 The major new feature is a mechanism for counting the rate of unique
384 events. The new per_addr option counts the number of different
385 recipients that someone has sent messages to in the last time period. It
386 behaves like per_rcpt if all the recipient addresses are different, but
387 duplicate recipient addresses do not increase the measured rate. Like
388 the /count= option this is a general mechanism, so the per_addr option
389 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
390 example, measure the rate that a client uses different sender addresses
391 with the options per_mail/unique=$sender_address. There are further
392 details in the main documentation.

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

963
964PH/01 Another patch from the Sieve maintainer.
965
6a3bceb1
PH
966PH/02 When an IPv6 address is converted to a string for single-key lookup
967 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
968 dots are used instead of colons so that keys in lsearch files need not
969 contain colons. This was done some time before quoting was made available
970 in lsearch files. However, iplsearch files do require colons in IPv6 keys
971 (notated using the quote facility) so as to distinguish them from IPv4
972 keys. This meant that lookups for IP addresses in host lists did not work
973 for iplsearch lookups.
974
975 This has been fixed by arranging for IPv6 addresses to be expressed with
976 colons if the lookup type is iplsearch. This is not incompatible, because
977 previously such lookups could never work.
978
979 The situation is now rather anomolous, since one *can* have colons in
980 ordinary lsearch keys. However, making the change in all cases is
981 incompatible and would probably break a number of configurations.

986MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
987 conversion specification without a maximum field width, thereby enabling
988 a rogue spamd server to cause a buffer overflow. While nobody in their
989 right mind would setup Exim to query an untrusted spamd server, an
990 attacker that gains access to a server running spamd could potentially
991 exploit this vulnerability to run arbitrary code as the Exim user.

996MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
997 a directory entry by the name of the lookup key. Previously, if a
998 symlink pointed to a non-existing file or a file in a directory that
999 Exim lacked permissions to read, a lookup for a key matching that
1000 symlink would fail. Now it is enough that a matching directory entry
1001 exists, symlink or not. (Bugzilla 503.)

1184PH/29 SMTP synchronization checks are implemented when a command is read -
1185 there is a check that no more input is waiting when there shouldn't be

1187 some time before the response is written. In this time, more input might
1188 arrive, invalidly. So now there are extra checks after an ACL has run for
1189 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1190 pipelining has not been advertised.

1205 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1206 was a macro that became an assignment, so it seemed to work. This has
1207 changed to a proper function call with a void return, hence the compile

1264 the response to the final '.' that terminates a message, but only in the

1266 (unfortunately, this is allowed). However, in many cases there won't be
1267 any further data because there won't be any more messages to send. A call
1268 to select() can be used: if it shows that the input is "ready", there is
1269 either input waiting, or the socket has been closed. An attempt to read
1270 the next input character can distinguish the two cases. Previously, Exim

1282PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1283 fixed by 4.65/MH/01 (is this a record?) are fixed:
1284
1285 (i) An empty string was always treated as zero by the numeric comparison
1286 operators. This behaviour has been restored.
1287
1288 (ii) It is documented that the numeric comparison operators always treat
1289 their arguments as decimal numbers. This was broken in that numbers
1290 starting with 0 were being interpreted as octal.
1291
1292 While fixing these problems I realized that there was another issue that
1293 hadn't been noticed. Values of message_size_limit (both the global option
1294 and the transport option) were treated as octal if they started with 0.
1295 The documentation was vague. These values are now always treated as
1296 decimal, and I will make that clear in the documentation.

PH
1340PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1341 callout verification, Exim cached a "reject" for the entire domain. This
1342 is correct for most verifications, but it is not correct for a recipient
1343 verification with use_sender or use_postmaster set, because in that case
1344 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1345 case of MAIL FROM:<> rejection from other early rejections (e.g.
1346 rejection of HELO). When verifying a recipient using a non-null MAIL
1347 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1348 Whatever the result of the callout, the value of the domain cache is
1349 left unchanged (for any other kind of callout, getting as far as trying
1350 RCPT means that the domain itself is ok).

1386 probably the interface on which it is arriving) and not to the outgoing
1387 callout (which could be using a different interface). This has been
1388 changed to use the value of the helo_data option from the smtp transport
1389 instead - this is what is used when a message is actually being sent. If
1390 there is no remote transport (possible with a router that sets up host

14aa5a05
PH
1395 (a) The code assumed that strncpy() returns a negative number on buffer
1396 overflow, which isn't the case. Replaced with Exim's string_format()
1397 function.
1398 (b) There were several signed/unsigned issues. I just did the minimum
1399 hacking in of casts. There is scope for a larger refactoring.
1400 (c) The code used strcasecmp() which is not a standard C function.
1401 Replaced with Exim's strcmpic() function.
1402 (d) The code set only $1; it now sets $auth1 as well.
1403 (e) A simple test gave the error "authentication client didn't specify
1404 service in request". It would seem that Dovecot has changed its
1405 interface. Fortunately there's a specification; I followed it and
1406 changed what the client sends and it appears to be working now.

1413 -v the output is "A verified" because verification stops after a
1414 successful redirection if more than one address is generated. However,
1415 with -v the child addresses are also verified. Exim was outputting "A
1416 failed to verify" and then showing the successful verification for C,
1417 with its parentage. It now outputs "B failed to verify", showing B's
1418 parentage before showing the successful verification of C.

PH
1424PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1425 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1426 they consult the DNS. I had assumed they would set it the way they
1427 wanted; and indeed my experiments on Linux seem to show that in some
1428 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1429 To be on the safe side, however, I have now made the interface to
1430 host_find_byname() similar to host_find_bydns(), with an argument
1431 containing the DNS resolver options. The host_find_byname() function now
1432 sets these options at its start, just as host_find_bydns() does. The smtp
1433 transport options dns_qualify_single and dns_search_parents are passed to
1434 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1435 of host_find_byname() use the default settings of RES_DEFNAMES
1436 (qualify_single) but not RES_DNSRCH (search_parents).

1438PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1439 spool_read_header() do less string testing, by means of a preliminary
1440 switch on the second character of optional "-foo" lines. (This is
1441 overdue, caused by the large number of possibilities that now exist.
1442 Originally there were few.) While I was there, I also converted the
1443 str(n)cmp tests so they don't re-test the leading "-" and the first
1444 character, in the hope this might squeeze out yet more improvement.

1446PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1447 flag allowing group syntax was set by the header_syntax check but not
1448 turned off, possible causing trouble later; (2) The flag was not being
1449 set at all for the header_verify test, causing "group"-style headers to
1450 be rejected. I have now set it in this case, and also caused header_
1451 verify to ignore an empty address taken from a group. While doing this, I
1452 came across some other cases where the code for allowing group syntax
1453 while scanning a header line wasn't quite right (mostly, not resetting
1454 the flag correctly in the right place). These bugs could have caused
1455 trouble for malformed header lines. I hope it is now all correct.

PH
1457PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1459 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1460 but it didn't always do it. This confused somebody who was copying the
1461 code for some other use. I have removed all the tests.

PH
1463PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1464 feature that was used to support insecure browsers during the U.S. crypto
1465 embargo. It requires special client support, and Exim is probably the
1466 only MTA that supported it -- and would never use it because real RSA is
1467 always available. This code has been removed, because it had the bad
1468 effect of slowing Exim down by computing (never used) parameters for the
1469 RSA_EXPORT functionality.

1475 if the connection is using TLS or if the remote IP is the same as the
1476 local IP, and the "valid-client-cert option" if a client certificate has

1508
1509PH/30 Exim was sometimes attempting to deliver messages that had suffered
1510 address errors (4xx response to RCPT) over the same connection as other
1511 messages routed to the same hosts. Such deliveries are always "forced",
1512 so retry times are not inspected. This resulted in far too many retries
1513 for the affected addresses. The effect occurred only when there were more
1514 hosts than the hosts_max_try setting in the smtp transport when it had
1515 the 4xx errors. Those hosts that it had tried were not added to the list
1516 of hosts for which the message was waiting, so if all were tried, there
1517 was no problem. Two fixes have been applied:
1518
1519 (i) If there are any address or message errors in an SMTP delivery, none
1520 of the hosts (tried or untried) are now added to the list of hosts
1521 for which the message is waiting, so the message should not be a
1522 candidate for sending over the same connection that was used for a
1523 successful delivery of some other message. This seems entirely
1524 reasonable: after all the message is NOT "waiting for some host".
1525 This is so "obvious" that I'm not sure why it wasn't done
1526 previously. Hope I haven't missed anything, but it can't do any
1527 harm, as the worst effect is to miss an optimization.
1528
1529 (ii) If, despite (i), such a delivery is accidentally attempted, the
1530 routing retry time is respected, so at least it doesn't keep
1531 hammering the server.

1546PH/35 The error "getsockname() failed: connection reset by peer" was being
1547 written to the panic log as well as the main log, but it isn't really

1549 removed the panic log writing for the ECONNRESET error when getsockname()
1550 fails.

48c7f9e2
PH
1552PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1553 runs only) independently of the message's sender address. This meant
1554 that, if the 4xx error was in fact related to the sender, a different
1555 message to the same recipient with a different sender could confuse
1556 things. In particualar, this can happen when sending to a greylisting
1557 server, but other circumstances could also provoke similar problems.
1558 I have changed the default so that the retry time for these errors is now
1559 based a combination of the sender and recipient addresses. This change
1560 can be overridden by setting address_retry_include_sender=false in the
1561 smtp transport.

1829PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1831 Unfortunately, if there is a major crisis, such as a disk failure,
1832 tcp-wrappers gives "deny", whereas what one would like would be some
1833 kind of temporary error. A kludge has been added to help with this.
1834 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1835 554 error is used if errno is still zero or contains ENOENT (which occurs
1836 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1877 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

1922 autoreply, Exim could try to deliver to a non-existent relative file

1959 major problems that occur when a DNS server includes only records of one
1960 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1961 fixed another bug: if SRV records were looked up and the corresponding
1962 address records were *not* found in the additional section, the port
1963 values from the SRV records were lost.

1973PH/19 When calculating a retry time, Exim used to measure the "time since
1974 failure" by looking at the "first failed" field in the retry record. Now
1975 it does not use this if it is later than than the arrival time of the
1976 message. Instead it uses the arrival time. This makes for better
1977 behaviour in cases where some deliveries succeed, thus re-setting the
1978 "first failed" field. An example is a quota failure for a huge message
1979 when small messages continue to be delivered. Without this change, the
1980 "time since failure" will always be short, possible causing more frequent
1981 delivery attempts for the huge message than are intended.

2078PH/42 The content-scanning code uses fopen() to create files in which to put
2079 message data. Previously it was not paying any attention to the mode of
2080 the files. Exim runs with umask(0) because the rest of the code creates
2081 files with open(), and sets the required mode explicitly. Thus, these
2082 files were ending up world-writeable. This was not a big issue, because,
2083 being within the spool directory, they were not world-accessible. I have
2084 created a function called modefopen, which takes an additional mode
2085 argument. It sets umask(777), creates the file, chmods it to the required
2086 mode, then resets the umask. All the relevant calls to fopen() in the
2087 content scanning code have been changed to use this function.

2124
2125 (i) Exim was not creating retry information for temporary errors given
2126 for individual recipients after the DATA command when the smtp transport
2127 was used in LMTP mode. This meant that they could be retried too
2128 frequently, and not timed out correctly.
2129
2130 (ii) Exim was setting the flag that allows error details to be returned
2131 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2132 recipients that were returned after the DATA command.
2133
2134PH/53 This is related to PH/52, but is more general: for any failing address,
2135 when detailed error information was permitted to be returned to the
2136 sender, but the error was temporary, then after the final timeout, only
2137 "retry timeout exceeded" was returned. Now it returns the full error as

2208PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2209 function verify_get_ident() calls ip_connect() to connect a socket, but
2210 if the "connect()" function timed out, ip_connect() used to close the
2211 socket. However, verify_get_ident() also closes the socket later, and in
2212 between Exim writes to the log, which may get opened at this point. When
2213 the socket was closed in ip_connect(), the log could get the same file
2214 descriptor number as the socket. This naturally causes chaos. The fix is
2215 not to close the socket in ip_connect(); the socket should be closed by
2216 the function that creates it. There was only one place in the code where
2217 this was missing, in the iplookup router, which I don't think anybody now
2218 uses, but I've fixed it anyway.

2279
2280 Received: from [1.2.3.4] (helo=[1.2.3.4])

2376 addresses acquired from the DNS when checking that the found name did
2377 have the original IP as one of its addresses. Since any found IPv6
2378 addresses are likely to be in abbreviated form, the comparison could
2379 fail. Luckily, there already exists a function for doing the comparison
2380 by converting both addresses to binary, so now that is used instead of
2381 the text comparison.

PH
2383PH/20 There was another similar case to PH/19, when a complete host name was
2384 given in a host list; looking up its IP address could give an abbreviated
2385 form, whereas the current host's name might or might not be abbreviated.
2386 The same fix has been applied.

2898
2899PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2900 that changes the way the GnuTLS parameters are stored in the cache file.
2901 The new format can be generated externally. For backward compatibility,
2902 if the data in the cache doesn't make sense, Exim assumes it has read an
2903 old-format file, and it generates new data and writes a new file. This
2904 means that you can't go back to an older release without removing the
2905 file.
2906
2907PH/03 A redirect router that has both "unseen" and "one_time" set does not
2908 work if there are any delivery delays because "one_time" forces the
2909 parent to be marked "delivered", so its unseen clone is never tried
2910 again. For this reason, Exim now forbids the simultaneous setting of
2911 these two options.

2913PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2914 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2915 entry if you want to know the details. The fix, however, neglected to
2916 consider the case when local delivery batching is involved. The test for
2917 "previously delivered" was not happening when checking to see if an
2918 address could be batched with a previous (undelivered) one; under
2919 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2920 address.

2925PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2926 header_syntax) but Exim was just ignoring anything given after a slash.
2927 In particular, this caused confusion with an attempt to use "verify =
2928 reverse_host_lookup/defer_ok". An error is now given when options are
2929 supplied for verify items that do not have them. (Maybe reverse_host_
2930 lookup should have a defer_ok option, but that's a different point.)

2932PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2985 the file with the wrong ownership). There was no test for failure of this
2986 fork() call, which would lead to the process getting stuck as it waited
2987 for a non-existent subprocess. Forks do occasionally fail when resources
2988 run out. I reviewed all the other calls to fork(); they all seem to check

2995 string after "input=" when read() returned zero. If read() returned -1

3008PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3009 hadn't been configured. The fix is from Juergen Kreileder, who
3010 understands it better than I do:
3011
3012 "Here's what I see happening with three configured cyrus_sasl
3013 authenticators configured (plain, login, cram-md5):
3014
3015 On startup auth_cyrus_sasl_init() gets called for each of these.
3016 This means three calls to sasl_listmech() without a specified mech_list.
3017 => SASL tests which mechs of all available mechs actually work
3018 => three warnings about OTP not working
3019 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3020
3021 With the patch, sasl_listmech() also gets called three times. But now
3022 SASL's mech_list option is set to the server_mech specified in the the
3023 authenticator. Or in other words, the answer from sasl_listmech()
3024 gets limited to just the mech you're testing for (which is different
3025 for each call.)
3026 => the return list contains just 'plain' or 'login', 'cram-md5' or
3027 nothing depending on the value of ob->server_mech.
3028
3029 I've just tested the patch: Authentication still works fine,

PH
3095PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3096 the grounds that routing the same address twice would always produce the
3097 same answer. This might have been true once, but it is certainly no
3098 longer true now. Routing a child address may depend on the previous
3099 routing that produced that child. Some complicated redirection strategies
3100 went wrong when messages had multiple recipients, and made Exim's
3101 behaviour dependent on the order in which the addresses were given.
3102
3103 I have moved the duplicate checking until after the routing is complete.
3104 Exim scans the addresses that are assigned to local and remote
3105 transports, and removes any duplicates. This means that more work will be
3106 done, as duplicates will always all be routed, but duplicates are
3107 presumably rare, so I don't expect this is of any significance.
3108
3109 For deliveries to pipes, files, and autoreplies, the duplicate checking
3110 still happens during the routing process, since they are not going to be
3111 routed further.

3152PH/45 In a pipe transport, although a timeout while waiting for the pipe

3155 successful delivery. Such timeouts include transport filter timeouts. For
3156 consistency with the overall process timeout, these timeouts are now
3157 treated as errors, giving rise to delivery failures by default. However,
3158 there is now a new Boolean option for the pipe transport called
3159 timeout_defer, which, if set TRUE, converts the failures into defers for
3160 both kinds of timeout. A transport filter timeout is now identified in

3166 from the Makefile to this script so that it can call the same version of
3167 "make".

3170A note about Exim versions 4.44 and 4.50
3171----------------------------------------
3172
3173Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3174changes of various kinds. As a consequence, a big documentation update was
3175needed. This delayed the release for rather longer than seemed good, especially
3176in the light of a couple of (minor) security issues. Therefore, the changes
3177that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3178release. So 4.44 and 4.50 are in effect two different branches that both start
3179from 4.43.
3180
3181I have left the 4.50 change log unchanged; it contains all the changes since
31824.43. The change log for 4.44 is below; many of its items are identical to
3183those for 4.50. This seems to be the most sensible way to preserve the
3184historical information.

PH
3190 1. Minor wording change to the doc/README.SIEVE file.
3191
139059f6 3192 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 3193 computation of the current number of files was incorrect.
495ae4b0 3194

PH
3195 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3196 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3197 place.
3198
35af9f61
PH
3199 4. Give more explanation in the error message when the command for a transport
3200 filter fails to execute.
3201
b668c215
PH
3202 5. There are several places where Exim runs a non-Exim command in a
3203 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3204 was being done only for the command run by the queryprogram router. It is
3205 now done for all such subprocesses. The other cases are: ${run, transport
3206 filters, and the commands run by the lmtp and pipe transports.
3207
a494b1e1
PH
3208 6. Added CONFIGURE_GROUP build-time option.
3209
3210 7. Some older OS have a limit of 256 on the maximum number of file
3211 descriptors. Exim was using setrlimit() to set 1000 as a large value
3212 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3213 systems. I've change it so that if it can't get 1000, it tries for 256.

PH
3215 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3216 was an oversight, and furthermore, ever since the addition of extra
3217 controls (e.g. 4.43/32), the checks on when to allow different forms of
3218 "control" were broken. There should now be diagnostics for all cases when a
3219 control that does not make sense is encountered.
3220
69358f02
PH
3221 9. Added the /retain_sender option to "control=submission".
3222
5be20824
PH
322310. $recipients is now available in the predata ACL (oversight).
3224
eb2c0248
PH
322511. Tidy the search cache before the fork to do a delivery from a message
3226 received from the command line. Otherwise the child will trigger a lookup
3227 failure and thereby defer the delivery if it tries to use (for example) a
3228 cached ldap connection that the parent has called unbind on.
3229
2a3eea10
PH
323012. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3231 of $address_data from the recipient verification was clobbered by the
3232 sender verification.
3233
323413. The value of address_data from a sender verification is now available in
3235 $sender_address_data in subsequent conditions in the ACL statement.
3236
23c7ff99
PH
323714. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3238
4deaf07d
PH
323915. Added a new option "connect=<time>" to callout options, to set a different
3240 connection timeout.
3241
926e1192
PH
324216. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3243 was its contents. (It was OK if the option was not defined at all.)
3244
650edc6f
PH
324517. A "Completed" log line is now written for messages that are removed from
3246 the spool by the -Mrm option.
3247
2c7db3f5
PH
324818. New variables $sender_verify_failure and $recipient_verify_failure contain
3249 information about exactly what failed.
3250
3d235903
PH
325119. Added -dd to debug only the daemon process.
3252
7c7ad977
PH
325320. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3254 handles timeouts, both on the server side and network timeouts. Renamed the
3255 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3256
981756db
PH
325721. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3258 It is now set to "smtps".
3259
d4eb88df
PH
326022. $host_address is now set to the target address during the checking of
3261 ignore_target_hosts.
3262
326323. When checking ignore_target_hosts for an ipliteral router, no host name was
3264 being passed; this would have caused $sender_host_name to have been used if
3265 matching the list had actually called for a host name (not very likely,
3266 since this list is usually IP addresses). A host name is now passed as
3267 "[x.x.x.x]".
3268
7d468ab8
PH
326924. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3270 code that specifies a non-restarting handler (typically sigaction() in
3271 modern systems) in an attempt to fix a rare and obscure crash bug.
3272
327325. Narrowed the window for a race in the daemon that could cause it to ignore
3274 SIGCHLD signals. This is not a major problem, because they are used only to
3275 wake it up if nothing else does.
3276
62c0818f
PH
327726. A malformed maildirsize file could cause Exim to calculate negative values
3278 for the mailbox size or file count. Odd effects could occur as a result.
3279 The maildirsize information is now recalculated if the size or filecount
3280 end up negative.
3281
26034054
PH
328227. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3283 support for a long time. Removed HAVE_SYS_VFS_H.
3284
af66f652
PH
328528. Installed the latest version of exipick from John Jetmore.
3286
90af77f4
PH
328729. In an address list, if the pattern was not a regular expression, an empty
3288 subject address (from a bounce message) matched only if the pattern was an
3289 empty string. Non-empty patterns were not even tested. This was the wrong
3290 because it is perfectly reasonable to use an empty address as part of a
3291 database query. An empty address is now tested by patterns that are
3292 lookups. However, all the other forms of pattern expect the subject to
3293 contain a local part and a domain, and therefore, for them, an empty
3294 address still always fails if the pattern is not itself empty.
3295
d8ef3577
PH
329630. Exim went into a mad DNS loop when attempting to do a callout where the
3297 host was specified on an smtp transport, and looking it up yielded more
3298 than one IP address.
3299
5cb8cbc6
PH
330031. Re-factored the code for checking spool and log partition space into a
3301 function that finds that data and another that does the check. The former
3302 is then used to implement four new variables: $spool_space, $log_space,
3303 $spool_inodes, and $log_inodes.
3304
14702f5b
PH
330532. The RFC2047 encoding function was originally intended for short strings
3306 such as real names; it was not keeping to the 75-character limit for
3307 encoded words that the RFC imposes. It now respects the limit, and
3308 generates multiple encoded words if necessary. To be on the safe side, I
3309 have increased the buffer size for the ${rfc2047: expansion operator from
3310 1024 to 2048 bytes.
3311
063b1e99
PH
331233. It is now permitted to omit both strings after an "if" condition; if the
3313 condition is true, the result is "true". As before, when the second string
3314 is omitted, a false condition yields an empty string. This makes it less
3315 cumbersome to write custom ACL and router conditions.
3316
652e1b65
PH
331734. Failure to deliver a bounce message always caused it to be frozen, even if
3318 there was an errors_to setting on the router. The errors_to setting is now
3319 respected.
3320
6f0c9a4f
PH
332135. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3322 canonical form (fully expanded) before being placed in
3323 $sender_host_address.
3324
33397d19
PH
332536. The table in the code that translates DNS record types into text (T_A to
3326 "A" for instance) was missing entries for NS and CNAME. It is just possible
3327 that this could have caused confusion if both these types were looked up
3328 for the same domain, because the text type is used as part of Exim's
3329 per-process caching. But the chance of anyone hitting this buglet seems
3330 very small.
3331
7bb56e1f
PH
333237. The dnsdb lookup has been extended in a number of ways.
3333
3334 (1) There is a new type, "zns", which walks up the domain tree until it
3335 finds some nameserver records. It should be used with care.
3336
ea3bc19b
PH
3337 (2) There is a new type, "mxh", which is like "mx" except that it returns
3338 just the host names, not the priorities.
3339
3340 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3341 looked up. The behaviour when one of the lookups defers can be
3342 controlled by a keyword.
7bb56e1f 3343
ea3bc19b 3344 (4) It is now possible to specify the separator character for use when
7bb56e1f 3345 multiple records are returned.
33397d19 3346
0bcb2a0e
PH
334738. The dnslists ACL condition has been extended: it is now possible to supply
3348 a list of IP addresses and/or domains to be looked up in a particular DNS
3349 domain.
3350
2ac0e484
PH
335139. Added log_selector=+queue_time_overall.
3352
4e1fde53
PH
335340. When running the queue in the test harness, wait just a tad after forking a
3354 delivery process, to get repeatability of debugging output.
3355
de365ded
PH
335641. Include certificate and key file names in error message when GnuTLS fails
3357 to set them up, because the GnuTLS error message doesn't include the name
3358 of the failing file when there is a problem reading it.
3359
f05da2e8
PH
336042. Allow both -bf and -bF in the same test run.
3361
d6453af2
PH
336243. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3363
f7b63901
PH
336444. The "Exiscan patch" is now merged into the mainline Exim source.
3365
336645. Sometimes the final signoff response after QUIT could fail to get
3367 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3368 < 0 before doing a fflush(). This bug looks as though it goes back to the
3369 introduction of TLS in release 3.20, but "sometimes" must have been rare
3370 because the tests only now provoked it.
3371

PH
337246. Reset the locale to "C" after calling embedded Perl, in case it was changed
3373 (this can affect the format of dates).
3374
0ec020ea
PH
337547. exim_tidydb, when checking for the continued existence of a message for
3376 which it has found a message-specific retry record, was not finding
3377 messages that were in split spool directories. Consequently, it was
3378 deleting retry records that should have stayed in existence.

PH
338048. Steve fixed some bugs in eximstats.
3381
338249. The SPA authentication driver was not abandoning authentication and moving
3383 on to the next authenticator when an expansion was forced to fail,
3384 contradicting the general specification for all authenticators. Instead it
