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
116 This commit adds a proper retry rule check during routing so that
117 the final cutoff time is checked against the message's age. I also
118 took the opportunity to unify three very similar blocks of code.
119
120 I suspect this new check makes the old local delivery cutoff check
121 redundant, but I have not verified this so I left the code in place.

281 GNU libc to support some of the 64-bit stuff, should not lead to

310

TF
311TF/03 Make the exiwhat support code safe for signals. Previously Exim might
312 lock up or crash if it happened to be inside a call to libc when it
313 got a SIGUSR1 from exiwhat.
314
315 The SIGUSR1 handler appends the current process status to the process
316 log which is later printed by exiwhat. It used to use the general
317 purpose logging code to do this, but several functions it calls are
318 not safe for signals.
319
320 The new output code in the SIGUSR1 handler is specific to the process
321 log, and simple enough that it's easy to inspect for signal safety.
322 Removing some special cases also simplifies the general logging code.
323 Removing the spurious timestamps from the process log simplifies
324 exiwhat.
325
c99ce5c9
TF
326TF/04 Improved ratelimit ACL condition.
327
328 The /noupdate option has been deprecated in favour of /readonly which
329 has clearer semantics. The /leaky, /strict, and /readonly update modes
330 are mutually exclusive. The update mode is no longer included in the
331 database key; it just determines when the database is updated. (This
332 means that when you upgrde Exim will forget old rate measurements.)
333
334 Exim now checks that the per_* options are used with an update mode that
335 makes sense for the current ACL. For example, when Exim is processing a
336 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
337 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
338 must specify per_mail/readonly. If you omit the update mode it defaults to
339 /leaky where that makes sense (as before) or /readonly where required.
340
341 The /noupdate option is now undocumented but still supported for
342 backwards compatibility. It is equivalent to /readonly except that in
343 ACLs where /readonly is required you may specify /leaky/noupdate or
344 /strict/noupdate which are treated the same as /readonly.
345
346 A useful new feature is the /count= option. This is a generalization
347 of the per_byte option, so that you can measure the throughput of other
348 aggregate values. For example, the per_byte option is now equivalent
349 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
350
351 The per_rcpt option has been generalized using the /count= mechanism
352 (though it's more complicated than the per_byte equivalence). When it is
353 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
354 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
355 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
356 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
357 Note that using per_rcpt with a non-readonly update mode in more than
358 one ACL will cause the recipients to be double-counted. (The per_mail
359 and per_byte options don't have this problem.)
360
361 The handling of very low rates has changed slightly. If the computed rate
362 is less than the event's count (usually one) then this event is the first
363 after a long gap. In this case the rate is set to the same as this event's
364 count, so that the first message of a spam run is counted properly.
365
366 The major new feature is a mechanism for counting the rate of unique
367 events. The new per_addr option counts the number of different
368 recipients that someone has sent messages to in the last time period. It
369 behaves like per_rcpt if all the recipient addresses are different, but
370 duplicate recipient addresses do not increase the measured rate. Like
371 the /count= option this is a general mechanism, so the per_addr option
372 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
373 example, measure the rate that a client uses different sender addresses
374 with the options per_mail/unique=$sender_address. There are further
375 details in the main documentation.

924
925 Note to Michael Haardt: I had to rename some vars in sieve.c. They
926 were called 'true' and it seems that C99 defines that as a reserved
927 keyword to be used with 'bool' variable types. That means you could
928 not include C99-style headers which use bools without triggering
929 build errors in sieve.c.

947PH/01 Another patch from the Sieve maintainer.
948
6a3bceb1
PH
949PH/02 When an IPv6 address is converted to a string for single-key lookup
950 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
951 dots are used instead of colons so that keys in lsearch files need not
952 contain colons. This was done some time before quoting was made available
953 in lsearch files. However, iplsearch files do require colons in IPv6 keys
954 (notated using the quote facility) so as to distinguish them from IPv4
955 keys. This meant that lookups for IP addresses in host lists did not work
956 for iplsearch lookups.
957
958 This has been fixed by arranging for IPv6 addresses to be expressed with
959 colons if the lookup type is iplsearch. This is not incompatible, because
960 previously such lookups could never work.
961
962 The situation is now rather anomolous, since one *can* have colons in
963 ordinary lsearch keys. However, making the change in all cases is
964 incompatible and would probably break a number of configurations.

969MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
970 conversion specification without a maximum field width, thereby enabling
971 a rogue spamd server to cause a buffer overflow. While nobody in their
972 right mind would setup Exim to query an untrusted spamd server, an
973 attacker that gains access to a server running spamd could potentially
974 exploit this vulnerability to run arbitrary code as the Exim user.

978
0f2cbd1b
MH
979MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
980 a directory entry by the name of the lookup key. Previously, if a
981 symlink pointed to a non-existing file or a file in a directory that
982 Exim lacked permissions to read, a lookup for a key matching that
983 symlink would fail. Now it is enough that a matching directory entry
984 exists, symlink or not. (Bugzilla 503.)

1057PH/02 In an ACL statement such as

1060
1061 if a client was not listed at all, or was listed with a value other than
1062 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1063 the condition was not true (as it should be), so access was not denied.

PH
1167PH/29 SMTP synchronization checks are implemented when a command is read -
1168 there is a check that no more input is waiting when there shouldn't be
1169 any. However, for some commands, a delay in an ACL can mean that it is
1170 some time before the response is written. In this time, more input might
1171 arrive, invalidly. So now there are extra checks after an ACL has run for
1172 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1173 pipelining has not been advertised.

PH
1185PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1186 Exim which did not show up earlier: it was assuming that a call to
1187 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1188 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()

1247 the response to the final '.' that terminates a message, but only in the
1248 case where the client has not sent further data following the '.'
1249 (unfortunately, this is allowed). However, in many cases there won't be
1250 any further data because there won't be any more messages to send. A call
1251 to select() can be used: if it shows that the input is "ready", there is
1252 either input waiting, or the socket has been closed. An attempt to read
1253 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1254 would have sent an OK response which the client would never have see.

1264
1265PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1266 fixed by 4.65/MH/01 (is this a record?) are fixed:
1267
1268 (i) An empty string was always treated as zero by the numeric comparison
1269 operators. This behaviour has been restored.
1270
1271 (ii) It is documented that the numeric comparison operators always treat
1272 their arguments as decimal numbers. This was broken in that numbers
1273 starting with 0 were being interpreted as octal.
1274
1275 While fixing these problems I realized that there was another issue that
1276 hadn't been noticed. Values of message_size_limit (both the global option
1277 and the transport option) were treated as octal if they started with 0.
1278 The documentation was vague. These values are now always treated as
1279 decimal, and I will make that clear in the documentation.

1296 large number of recipients for a single message is ridiculous
1297 (performance will be very, very poor), I have chosen to impose a limit
1298 rather than extend the field.

PH
1323PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1324 callout verification, Exim cached a "reject" for the entire domain. This
1325 is correct for most verifications, but it is not correct for a recipient
1326 verification with use_sender or use_postmaster set, because in that case
1327 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1328 case of MAIL FROM:<> rejection from other early rejections (e.g.
1329 rejection of HELO). When verifying a recipient using a non-null MAIL
1330 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1331 Whatever the result of the callout, the value of the domain cache is
1332 left unchanged (for any other kind of callout, getting as far as trying
1333 RCPT means that the domain itself is ok).

1369 probably the interface on which it is arriving) and not to the outgoing
1370 callout (which could be using a different interface). This has been
1371 changed to use the value of the helo_data option from the smtp transport
1372 instead - this is what is used when a message is actually being sent. If
1373 there is no remote transport (possible with a router that sets up host
1374 addresses), $smtp_active_hostname is used.

14aa5a05
PH
1378 (a) The code assumed that strncpy() returns a negative number on buffer
1379 overflow, which isn't the case. Replaced with Exim's string_format()
1380 function.
1381 (b) There were several signed/unsigned issues. I just did the minimum
1382 hacking in of casts. There is scope for a larger refactoring.
1383 (c) The code used strcasecmp() which is not a standard C function.
1384 Replaced with Exim's strcmpic() function.
1385 (d) The code set only $1; it now sets $auth1 as well.
1386 (e) A simple test gave the error "authentication client didn't specify
1387 service in request". It would seem that Dovecot has changed its
1388 interface. Fortunately there's a specification; I followed it and
1389 changed what the client sends and it appears to be working now.

1396 -v the output is "A verified" because verification stops after a
1397 successful redirection if more than one address is generated. However,
1398 with -v the child addresses are also verified. Exim was outputting "A
1399 failed to verify" and then showing the successful verification for C,
1400 with its parentage. It now outputs "B failed to verify", showing B's
1401 parentage before showing the successful verification of C.

PH
1407PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1408 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1409 they consult the DNS. I had assumed they would set it the way they
1410 wanted; and indeed my experiments on Linux seem to show that in some
1411 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1412 To be on the safe side, however, I have now made the interface to
1413 host_find_byname() similar to host_find_bydns(), with an argument
1414 containing the DNS resolver options. The host_find_byname() function now
1415 sets these options at its start, just as host_find_bydns() does. The smtp
1416 transport options dns_qualify_single and dns_search_parents are passed to
1417 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1418 of host_find_byname() use the default settings of RES_DEFNAMES
1419 (qualify_single) but not RES_DNSRCH (search_parents).

1422 spool_read_header() do less string testing, by means of a preliminary
1423 switch on the second character of optional "-foo" lines. (This is
1424 overdue, caused by the large number of possibilities that now exist.
1425 Originally there were few.) While I was there, I also converted the
1426 str(n)cmp tests so they don't re-test the leading "-" and the first
1427 character, in the hope this might squeeze out yet more improvement.

1429PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1430 flag allowing group syntax was set by the header_syntax check but not
1431 turned off, possible causing trouble later; (2) The flag was not being
1432 set at all for the header_verify test, causing "group"-style headers to
1433 be rejected. I have now set it in this case, and also caused header_
1434 verify to ignore an empty address taken from a group. While doing this, I
1435 came across some other cases where the code for allowing group syntax
1436 while scanning a header line wasn't quite right (mostly, not resetting
1437 the flag correctly in the right place). These bugs could have caused
1438 trouble for malformed header lines. I hope it is now all correct.

PH
1440PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1442 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1443 but it didn't always do it. This confused somebody who was copying the
1444 code for some other use. I have removed all the tests.

PH
1446PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1447 feature that was used to support insecure browsers during the U.S. crypto
1448 embargo. It requires special client support, and Exim is probably the
1449 only MTA that supported it -- and would never use it because real RSA is
1450 always available. This code has been removed, because it had the bad
1451 effect of slowing Exim down by computing (never used) parameters for the
1452 RSA_EXPORT functionality.

1457 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1458 if the connection is using TLS or if the remote IP is the same as the
1459 local IP, and the "valid-client-cert option" if a client certificate has
1460 been verified.

PH
1491
1492PH/30 Exim was sometimes attempting to deliver messages that had suffered
1493 address errors (4xx response to RCPT) over the same connection as other
1494 messages routed to the same hosts. Such deliveries are always "forced",
1495 so retry times are not inspected. This resulted in far too many retries
1496 for the affected addresses. The effect occurred only when there were more
1497 hosts than the hosts_max_try setting in the smtp transport when it had
1498 the 4xx errors. Those hosts that it had tried were not added to the list
1499 of hosts for which the message was waiting, so if all were tried, there
1500 was no problem. Two fixes have been applied:
1501
1502 (i) If there are any address or message errors in an SMTP delivery, none
1503 of the hosts (tried or untried) are now added to the list of hosts
1504 for which the message is waiting, so the message should not be a
1505 candidate for sending over the same connection that was used for a
1506 successful delivery of some other message. This seems entirely
1507 reasonable: after all the message is NOT "waiting for some host".
1508 This is so "obvious" that I'm not sure why it wasn't done
1509 previously. Hope I haven't missed anything, but it can't do any
1510 harm, as the worst effect is to miss an optimization.
1511
1512 (ii) If, despite (i), such a delivery is accidentally attempted, the
1513 routing retry time is respected, so at least it doesn't keep
1514 hammering the server.

1529PH/35 The error "getsockname() failed: connection reset by peer" was being
1530 written to the panic log as well as the main log, but it isn't really

1532 removed the panic log writing for the ECONNRESET error when getsockname()
1533 fails.

48c7f9e2
PH
1535PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1536 runs only) independently of the message's sender address. This meant
1537 that, if the 4xx error was in fact related to the sender, a different
1538 message to the same recipient with a different sender could confuse
1539 things. In particualar, this can happen when sending to a greylisting
1540 server, but other circumstances could also provoke similar problems.
1541 I have changed the default so that the retry time for these errors is now
1542 based a combination of the sender and recipient addresses. This change
1543 can be overridden by setting address_retry_include_sender=false in the
1544 smtp transport.

1812PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".

1814 Unfortunately, if there is a major crisis, such as a disk failure,
1815 tcp-wrappers gives "deny", whereas what one would like would be some
1816 kind of temporary error. A kludge has been added to help with this.
1817 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1818 554 error is used if errno is still zero or contains ENOENT (which occurs
1819 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
1820 451 error is used.

1859 code found IPv4 interfaces correctly, but gave incorrect values for the
1860 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was

1905 autoreply, Exim could try to deliver to a non-existent relative file

1930 suitable debugging ouput when -d is set.

1941 Instead, it always explicitly searches for A/AAAA records. This avoids
1942 major problems that occur when a DNS server includes only records of one
1943 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
1944 fixed another bug: if SRV records were looked up and the corresponding
1945 address records were *not* found in the additional section, the port
1946 values from the SRV records were lost.

PH
1956PH/19 When calculating a retry time, Exim used to measure the "time since
1957 failure" by looking at the "first failed" field in the retry record. Now
1958 it does not use this if it is later than than the arrival time of the
1959 message. Instead it uses the arrival time. This makes for better
1960 behaviour in cases where some deliveries succeed, thus re-setting the
1961 "first failed" field. An example is a quota failure for a huge message
1962 when small messages continue to be delivered. Without this change, the
1963 "time since failure" will always be short, possible causing more frequent
1964 delivery attempts for the huge message than are intended.

PH
2061PH/42 The content-scanning code uses fopen() to create files in which to put
2062 message data. Previously it was not paying any attention to the mode of
2063 the files. Exim runs with umask(0) because the rest of the code creates
2064 files with open(), and sets the required mode explicitly. Thus, these
2065 files were ending up world-writeable. This was not a big issue, because,
2066 being within the spool directory, they were not world-accessible. I have
2067 created a function called modefopen, which takes an additional mode
2068 argument. It sets umask(777), creates the file, chmods it to the required
2069 mode, then resets the umask. All the relevant calls to fopen() in the
2070 content scanning code have been changed to use this function.

2081 received. Setting client_ignore_invalid_base64 true ignores these errors.
2082 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2083 they are received. Thus, the responses can be made to depend on the

2105PH/52 Two bugs concerned with error handling when the smtp transport is

2107
2108 (i) Exim was not creating retry information for temporary errors given
2109 for individual recipients after the DATA command when the smtp transport
2110 was used in LMTP mode. This meant that they could be retried too
2111 frequently, and not timed out correctly.
2112
2113 (ii) Exim was setting the flag that allows error details to be returned
2114 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2115 recipients that were returned after the DATA command.
2116
2117PH/53 This is related to PH/52, but is more general: for any failing address,
2118 when detailed error information was permitted to be returned to the
2119 sender, but the error was temporary, then after the final timeout, only
2120 "retry timeout exceeded" was returned. Now it returns the full error as

2191PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2192 function verify_get_ident() calls ip_connect() to connect a socket, but
2193 if the "connect()" function timed out, ip_connect() used to close the
2194 socket. However, verify_get_ident() also closes the socket later, and in
2195 between Exim writes to the log, which may get opened at this point. When
2196 the socket was closed in ip_connect(), the log could get the same file
2197 descriptor number as the socket. This naturally causes chaos. The fix is
2198 not to close the socket in ip_connect(); the socket should be closed by
2199 the function that creates it. There was only one place in the code where
2200 this was missing, in the iplookup router, which I don't think anybody now
2201 uses, but I've fixed it anyway.

2229 ${prvscheck and used in the second argument before leaving the code,
2230 because their memory is reclaimed, so using them afterwards may do
2231 silly things.

2258 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2259 not being looked up in the rDNS to get a host name, Exim was showing the
2260 IP address twice in Received: lines, even though the IP addresses were
2261 identical. For example:
2262
2263 Received: from [1.2.3.4] (helo=[1.2.3.4])
2264
2265 However, if the real host name was known, it was omitting the HELO data

2359 addresses acquired from the DNS when checking that the found name did
2360 have the original IP as one of its addresses. Since any found IPv6
2361 addresses are likely to be in abbreviated form, the comparison could
2362 fail. Luckily, there already exists a function for doing the comparison
2363 by converting both addresses to binary, so now that is used instead of
2364 the text comparison.

2663 Fortunately, Exim does not actually use EX_OK. The code used to try to
2664 preserve the sysexits.h value, by assumimg that macro definitions were
2665 scanned for macro replacements. I have been disabused of this notion,

2812 read the rcpt_include_affixes from the non-existent transport. Now it
2813 just assumes that the setting of that option is false. This bug was

2881
2882PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2883 that changes the way the GnuTLS parameters are stored in the cache file.
2884 The new format can be generated externally. For backward compatibility,
2885 if the data in the cache doesn't make sense, Exim assumes it has read an
2886 old-format file, and it generates new data and writes a new file. This
2887 means that you can't go back to an older release without removing the
2888 file.
2889
2890PH/03 A redirect router that has both "unseen" and "one_time" set does not
2891 work if there are any delivery delays because "one_time" forces the
2892 parent to be marked "delivered", so its unseen clone is never tried
2893 again. For this reason, Exim now forbids the simultaneous setting of
2894 these two options.

2896PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2897 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2898 entry if you want to know the details. The fix, however, neglected to
2899 consider the case when local delivery batching is involved. The test for
2900 "previously delivered" was not happening when checking to see if an
2901 address could be batched with a previous (undelivered) one; under
2902 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2903 address.

2907
2908PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2909 header_syntax) but Exim was just ignoring anything given after a slash.
2910 In particular, this caused confusion with an attempt to use "verify =
2911 reverse_host_lookup/defer_ok". An error is now given when options are
2912 supplied for verify items that do not have them. (Maybe reverse_host_
2913 lookup should have a defer_ok option, but that's a different point.)
2914
2915PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

2968 the file with the wrong ownership). There was no test for failure of this
2969 fork() call, which would lead to the process getting stuck as it waited
2970 for a non-existent subprocess. Forks do occasionally fail when resources
2971 run out. I reviewed all the other calls to fork(); they all seem to check

2977 the result was a log entry for a synchronization error with an empty
2978 string after "input=" when read() returned zero. If read() returned -1

PH
2991PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
2992 hadn't been configured. The fix is from Juergen Kreileder, who
2993 understands it better than I do:
2994
2995 "Here's what I see happening with three configured cyrus_sasl
2996 authenticators configured (plain, login, cram-md5):
2997
2998 On startup auth_cyrus_sasl_init() gets called for each of these.
2999 This means three calls to sasl_listmech() without a specified mech_list.
3000 => SASL tests which mechs of all available mechs actually work
3001 => three warnings about OTP not working
3002 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3003
3004 With the patch, sasl_listmech() also gets called three times. But now
3005 SASL's mech_list option is set to the server_mech specified in the the
3006 authenticator. Or in other words, the answer from sasl_listmech()
3007 gets limited to just the mech you're testing for (which is different
3008 for each call.)
3009 => the return list contains just 'plain' or 'login', 'cram-md5' or
3010 nothing depending on the value of ob->server_mech.
3011
3012 I've just tested the patch: Authentication still works fine,
3013 unavailable mechs specified in the exim configuration are still

PH
3078PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3079 the grounds that routing the same address twice would always produce the
3080 same answer. This might have been true once, but it is certainly no
3081 longer true now. Routing a child address may depend on the previous
3082 routing that produced that child. Some complicated redirection strategies
3083 went wrong when messages had multiple recipients, and made Exim's
3084 behaviour dependent on the order in which the addresses were given.
3085
3086 I have moved the duplicate checking until after the routing is complete.
3087 Exim scans the addresses that are assigned to local and remote
3088 transports, and removes any duplicates. This means that more work will be
3089 done, as duplicates will always all be routed, but duplicates are
3090 presumably rare, so I don't expect this is of any significance.
3091
3092 For deliveries to pipes, files, and autoreplies, the duplicate checking
3093 still happens during the routing process, since they are not going to be
3094 routed further.

3141 there is now a new Boolean option for the pipe transport called

3153A note about Exim versions 4.44 and 4.50
3154----------------------------------------
3155
3156Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3157changes of various kinds. As a consequence, a big documentation update was
3158needed. This delayed the release for rather longer than seemed good, especially
3159in the light of a couple of (minor) security issues. Therefore, the changes
3160that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3161release. So 4.44 and 4.50 are in effect two different branches that both start
3162from 4.43.
3163
3164I have left the 4.50 change log unchanged; it contains all the changes since
31654.43. The change log for 4.44 is below; many of its items are identical to
3166those for 4.50. This seems to be the most sensible way to preserve the
3167historical information.

5fe762f6
PH
3173 1. Minor wording change to the doc/README.SIEVE file.
3174
139059f6 3175 2. Change 4.43/35 introduced a bug: if quota_filecount was set, the
5fe762f6 3176 computation of the current number of files was incorrect.
495ae4b0 3177
7086e875
PH
3178 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The
3179 bug fixed in 4.43/37 would have been diagnosed quickly if this had been in
3180 place.
3181
35af9f61
PH
3182 4. Give more explanation in the error message when the command for a transport
3183 filter fails to execute.
3184
b668c215
PH
3185 5. There are several places where Exim runs a non-Exim command in a
3186 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3187 was being done only for the command run by the queryprogram router. It is
3188 now done for all such subprocesses. The other cases are: ${run, transport
3189 filters, and the commands run by the lmtp and pipe transports.
3190
a494b1e1
PH
3191 6. Added CONFIGURE_GROUP build-time option.
3192
3193 7. Some older OS have a limit of 256 on the maximum number of file
3194 descriptors. Exim was using setrlimit() to set 1000 as a large value
3195 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3196 systems. I've change it so that if it can't get 1000, it tries for 256.
35edf2ff 3197

PH
3198 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3199 was an oversight, and furthermore, ever since the addition of extra
3200 controls (e.g. 4.43/32), the checks on when to allow different forms of
3201 "control" were broken. There should now be diagnostics for all cases when a
3202 control that does not make sense is encountered.
3203
69358f02
PH
3204 9. Added the /retain_sender option to "control=submission".
3205
5be20824
PH
320610. $recipients is now available in the predata ACL (oversight).
3207
eb2c0248
PH
320811. Tidy the search cache before the fork to do a delivery from a message
3209 received from the command line. Otherwise the child will trigger a lookup
3210 failure and thereby defer the delivery if it tries to use (for example) a
3211 cached ldap connection that the parent has called unbind on.
3212
2a3eea10
PH
321312. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3214 of $address_data from the recipient verification was clobbered by the
3215 sender verification.
3216
321713. The value of address_data from a sender verification is now available in
3218 $sender_address_data in subsequent conditions in the ACL statement.
3219
23c7ff99
PH
322014. Added forbid_sieve_filter and forbid_exim_filter to the redirect router.
3221
4deaf07d
PH
322215. Added a new option "connect=<time>" to callout options, to set a different
3223 connection timeout.
3224
926e1192
PH
322516. If FIXED_NEVER_USERS was defined, but empty, Exim was assuming the uid 0
3226 was its contents. (It was OK if the option was not defined at all.)
3227
650edc6f
PH
322817. A "Completed" log line is now written for messages that are removed from
3229 the spool by the -Mrm option.
3230
2c7db3f5
PH
323118. New variables $sender_verify_failure and $recipient_verify_failure contain
3232 information about exactly what failed.
3233
3d235903
PH
323419. Added -dd to debug only the daemon process.
3235
7c7ad977
PH
323620. Incorporated Michael Haardt's patch to ldap.c for improving the way it
3237 handles timeouts, both on the server side and network timeouts. Renamed the
3238 CONNECT parameter as NETTIMEOUT (but kept the old name for compatibility).
3239
981756db
PH
324021. The rare case of EHLO->STARTTLS->HELO was setting the protocol to "smtp".
3241 It is now set to "smtps".
3242
d4eb88df
PH
324322. $host_address is now set to the target address during the checking of
3244 ignore_target_hosts.
3245
324623. When checking ignore_target_hosts for an ipliteral router, no host name was
3247 being passed; this would have caused $sender_host_name to have been used if
3248 matching the list had actually called for a host name (not very likely,
3249 since this list is usually IP addresses). A host name is now passed as
3250 "[x.x.x.x]".
3251
7d468ab8
PH
325224. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3253 code that specifies a non-restarting handler (typically sigaction() in
3254 modern systems) in an attempt to fix a rare and obscure crash bug.
3255
325625. Narrowed the window for a race in the daemon that could cause it to ignore
3257 SIGCHLD signals. This is not a major problem, because they are used only to
3258 wake it up if nothing else does.
3259
62c0818f
PH
326026. A malformed maildirsize file could cause Exim to calculate negative values
3261 for the mailbox size or file count. Odd effects could occur as a result.
3262 The maildirsize information is now recalculated if the size or filecount
3263 end up negative.
3264
26034054
PH
326527. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
3266 support for a long time. Removed HAVE_SYS_VFS_H.
3267
af66f652
PH
326828. Installed the latest version of exipick from John Jetmore.
3269
90af77f4
PH
327029. In an address list, if the pattern was not a regular expression, an empty
3271 subject address (from a bounce message) matched only if the pattern was an
3272 empty string. Non-empty patterns were not even tested. This was the wrong
3273 because it is perfectly reasonable to use an empty address as part of a
3274 database query. An empty address is now tested by patterns that are
3275 lookups. However, all the other forms of pattern expect the subject to
3276 contain a local part and a domain, and therefore, for them, an empty
3277 address still always fails if the pattern is not itself empty.
3278
d8ef3577
PH
327930. Exim went into a mad DNS loop when attempting to do a callout where the
3280 host was specified on an smtp transport, and looking it up yielded more
3281 than one IP address.
3282
5cb8cbc6
PH
328331. Re-factored the code for checking spool and log partition space into a
3284 function that finds that data and another that does the check. The former
3285 is then used to implement four new variables: $spool_space, $log_space,
3286 $spool_inodes, and $log_inodes.
3287
14702f5b
PH
328832. The RFC2047 encoding function was originally intended for short strings
3289 such as real names; it was not keeping to the 75-character limit for
3290 encoded words that the RFC imposes. It now respects the limit, and
3291 generates multiple encoded words if necessary. To be on the safe side, I
3292 have increased the buffer size for the ${rfc2047: expansion operator from
3293 1024 to 2048 bytes.
3294
063b1e99
PH
329533. It is now permitted to omit both strings after an "if" condition; if the
3296 condition is true, the result is "true". As before, when the second string
3297 is omitted, a false condition yields an empty string. This makes it less
3298 cumbersome to write custom ACL and router conditions.
3299
652e1b65
PH
330034. Failure to deliver a bounce message always caused it to be frozen, even if
3301 there was an errors_to setting on the router. The errors_to setting is now
3302 respected.
3303
6f0c9a4f
PH
330435. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3305 canonical form (fully expanded) before being placed in
3306 $sender_host_address.
3307
33397d19
PH
330836. The table in the code that translates DNS record types into text (T_A to
3309 "A" for instance) was missing entries for NS and CNAME. It is just possible
3310 that this could have caused confusion if both these types were looked up
3311 for the same domain, because the text type is used as part of Exim's
3312 per-process caching. But the chance of anyone hitting this buglet seems
3313 very small.
3314
7bb56e1f
PH
331537. The dnsdb lookup has been extended in a number of ways.
3316
3317 (1) There is a new type, "zns", which walks up the domain tree until it
3318 finds some nameserver records. It should be used with care.
3319
ea3bc19b
PH
3320 (2) There is a new type, "mxh", which is like "mx" except that it returns
3321 just the host names, not the priorities.
3322
3323 (3) It is now possible to give a list of domains (or IP addresses) to be
ff4dbb19
PH
3324 looked up. The behaviour when one of the lookups defers can be
3325 controlled by a keyword.
7bb56e1f 3326
ea3bc19b 3327 (4) It is now possible to specify the separator character for use when
7bb56e1f 3328 multiple records are returned.
33397d19 3329
0bcb2a0e
PH
333038. The dnslists ACL condition has been extended: it is now possible to supply
3331 a list of IP addresses and/or domains to be looked up in a particular DNS
3332 domain.
3333
2ac0e484
PH
333439. Added log_selector=+queue_time_overall.
3335
4e1fde53
PH
333640. When running the queue in the test harness, wait just a tad after forking a
3337 delivery process, to get repeatability of debugging output.
3338
de365ded
PH
333941. Include certificate and key file names in error message when GnuTLS fails
3340 to set them up, because the GnuTLS error message doesn't include the name
3341 of the failing file when there is a problem reading it.
3342
f05da2e8
PH
334342. Allow both -bf and -bF in the same test run.
3344
d6453af2
PH
334543. Did the same fix as 41 above for OpenSSL, which had the same infelicity.
3346
f7b63901
PH
334744. The "Exiscan patch" is now merged into the mainline Exim source.
3348
334945. Sometimes the final signoff response after QUIT could fail to get
3350 transmitted in the non-TLS case. Testing !tls_active instead of tls_active
3351 < 0 before doing a fflush(). This bug looks as though it goes back to the
3352 introduction of TLS in release 3.20, but "sometimes" must have been rare
3353 because the tests only now provoked it.
3354
a444213a
PH
335546. Reset the locale to "C" after calling embedded Perl, in case it was changed
3356 (this can affect the format of dates).
3357
0ec020ea
PH
335847. exim_tidydb, when checking for the continued existence of a message for
3359 which it has found a message-specific retry record, was not finding
3360 messages that were in split spool directories. Consequently, it was
3361 deleting retry records that should have stayed in existence.
3362
b1206957
PH
336348. Steve fixed some bugs in eximstats.
3364
336549. The SPA authentication driver was not abandoning authentication and moving
3366 on to the next authenticator when an expansion was forced to fail,
3367 contradicting the general specification for all authenticators. Instead it
3368 was generating a temporary error. It now behaves as specified.
3369
26dd5a95
PH
337050. The default ordering of permitted cipher suites for GnuTLS was pessimal
3371 (the order specifies the preference for clients). The order is now AES256,
3372 AES128, 3DES, ARCFOUR128.
3373
343b2385
PH
337451. Small patch to Sieve code - explicitly set From: when generating an
3375 autoreply.
3376
1c5466b9
PH
337752. Exim crashed if a remote delivery caused a very long error message to be
3378 recorded - for instance if somebody sent an entire SpamAssassin report back
3379 as a large number of 550 error lines. This bug was coincidentally fixed by
3380 increasing the size of one of Exim's internal buffers (big_buffer) that
3381 happened as part of the Exiscan merge. However, to be on the safe side, I
3382 have made the code more robust (and fixed the comments that describe what
3383 is going on).
