104TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
105
106 When a queue runner is handling a message, Exim first routes the
107 recipient addresses, during which it prunes them based on the retry
108 hints database. After that it attempts to deliver the message to
109 any remaining recipients. It then updates the hints database using
110 the retry rules.
111
112 So if a recipient address works intermittently, it can get repeatedly
113 deferred at routing time. The retry hints record remains fresh so the
114 address never reaches the final cutoff time.
115
116 This is a fairly common occurrence when a user is bumping up against
117 their storage quota. Exim had some logic in its local delivery code
118 to deal with this. However it did not apply to per-recipient defers
119 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
120
1ddeb334
TF
121 This change adds a proper retry rule check during routing so that the
122 final cutoff time is checked against the message's age. We only do
123 this check if there is an address retry record and there is not a
124 domain retry record; this implies that previous attempts to handle
125 the address had the retry_use_local_parts option turned on. We use
126 this as an approximation for the destination being like a local
127 delivery, as in LMTP.
67bd1ab3
TF
128
129 I suspect this new check makes the old local delivery cutoff check
130 redundant, but I have not verified this so I left the code in place.
131

TF
132TF/02 Correct gecos expansion when From: is a prefix of the username.
133
134 Test 0254 submits a message to Exim with the header
135
136 Resent-From: f
137
138 When I ran the test suite under the user fanf2, Exim expanded
139 the header to contain my full name, whereas it should have added
140 a Resent-Sender: header. It erroneously treats any prefix of the
141 username as equal to the username.
142
143 This change corrects that bug.

164JH/14 SMTP PRDR (http://www.eric-a-hall.com/specs/draft-hall-prdr-00.txt).
165 Server implementation by Todd Lyons, client by JH.
166 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
167 config variable "prdr_enable" controls whether the server
168 advertises the facility. If the client requests PRDR a new
169 acl_data_smtp_prdr ACL is called once for each recipient, after
170 the body content is received and before the acl_smtp_data ACL.
171 The client is controlled by bolth of: a hosts_try_prdr option
172 on the smtp transport, and the server advertisement.
173 Default client logging of deliveries and rejections involving
174 PRDR are flagged with the string "PRDR".

184 This is now consistent with GnuTLS, and is now documented: the
185 previous undocumented portable approach to treating the option as
186 unset was to force an expansion failure. That still works, and
187 an empty string is now equivalent.

189PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it

393TF/03 Make the exiwhat support code safe for signals. Previously Exim might
394 lock up or crash if it happened to be inside a call to libc when it
395 got a SIGUSR1 from exiwhat.
396
397 The SIGUSR1 handler appends the current process status to the process
398 log which is later printed by exiwhat. It used to use the general
399 purpose logging code to do this, but several functions it calls are
400 not safe for signals.
401
402 The new output code in the SIGUSR1 handler is specific to the process
403 log, and simple enough that it's easy to inspect for signal safety.
404 Removing some special cases also simplifies the general logging code.
405 Removing the spurious timestamps from the process log simplifies
406 exiwhat.

414 means that when you upgrde Exim will forget old rate measurements.)
415
416 Exim now checks that the per_* options are used with an update mode that
417 makes sense for the current ACL. For example, when Exim is processing a
418 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
419 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
420 must specify per_mail/readonly. If you omit the update mode it defaults to
421 /leaky where that makes sense (as before) or /readonly where required.
422
423 The /noupdate option is now undocumented but still supported for
424 backwards compatibility. It is equivalent to /readonly except that in
425 ACLs where /readonly is required you may specify /leaky/noupdate or
426 /strict/noupdate which are treated the same as /readonly.
427
428 A useful new feature is the /count= option. This is a generalization
429 of the per_byte option, so that you can measure the throughput of other
430 aggregate values. For example, the per_byte option is now equivalent
431 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
432
433 The per_rcpt option has been generalized using the /count= mechanism
434 (though it's more complicated than the per_byte equivalence). When it is
435 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
436 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
437 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
438 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
439 Note that using per_rcpt with a non-readonly update mode in more than
440 one ACL will cause the recipients to be double-counted. (The per_mail
441 and per_byte options don't have this problem.)
442
443 The handling of very low rates has changed slightly. If the computed rate
444 is less than the event's count (usually one) then this event is the first
445 after a long gap. In this case the rate is set to the same as this event's
446 count, so that the first message of a spam run is counted properly.
447
448 The major new feature is a mechanism for counting the rate of unique
449 events. The new per_addr option counts the number of different
450 recipients that someone has sent messages to in the last time period. It
451 behaves like per_rcpt if all the recipient addresses are different, but
452 duplicate recipient addresses do not increase the measured rate. Like
453 the /count= option this is a general mechanism, so the per_addr option
454 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
455 example, measure the rate that a client uses different sender addresses
456 with the options per_mail/unique=$sender_address. There are further
457 details in the main documentation.

1007 Note to Michael Haardt: I had to rename some vars in sieve.c. They
1008 were called 'true' and it seems that C99 defines that as a reserved
1009 keyword to be used with 'bool' variable types. That means you could
1010 not include C99-style headers which use bools without triggering
1011 build errors in sieve.c.

1030
6a3bceb1
PH
1031PH/02 When an IPv6 address is converted to a string for single-key lookup
1032 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1033 dots are used instead of colons so that keys in lsearch files need not
1034 contain colons. This was done some time before quoting was made available
1035 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1036 (notated using the quote facility) so as to distinguish them from IPv4
1037 keys. This meant that lookups for IP addresses in host lists did not work
1038 for iplsearch lookups.
1039
1040 This has been fixed by arranging for IPv6 addresses to be expressed with
1041 colons if the lookup type is iplsearch. This is not incompatible, because
1042 previously such lookups could never work.
1043
1044 The situation is now rather anomolous, since one *can* have colons in
1045 ordinary lsearch keys. However, making the change in all cases is
1046 incompatible and would probably break a number of configurations.

1051MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1052 conversion specification without a maximum field width, thereby enabling
1053 a rogue spamd server to cause a buffer overflow. While nobody in their
1054 right mind would setup Exim to query an untrusted spamd server, an
1055 attacker that gains access to a server running spamd could potentially
1056 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1061MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1062 a directory entry by the name of the lookup key. Previously, if a
1063 symlink pointed to a non-existing file or a file in a directory that
1064 Exim lacked permissions to read, a lookup for a key matching that
1065 symlink would fail. Now it is enough that a matching directory entry
1066 exists, symlink or not. (Bugzilla 503.)

PH
1249PH/29 SMTP synchronization checks are implemented when a command is read -
1250 there is a check that no more input is waiting when there shouldn't be
1251 any. However, for some commands, a delay in an ACL can mean that it is
1252 some time before the response is written. In this time, more input might
1253 arrive, invalidly. So now there are extra checks after an ACL has run for
1254 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1255 pipelining has not been advertised.

PH
1329 the response to the final '.' that terminates a message, but only in the
1330 case where the client has not sent further data following the '.'
1331 (unfortunately, this is allowed). However, in many cases there won't be
1332 any further data because there won't be any more messages to send. A call
1333 to select() can be used: if it shows that the input is "ready", there is
1334 either input waiting, or the socket has been closed. An attempt to read
1335 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1336 would have sent an OK response which the client would never have see.

1346
1347PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1348 fixed by 4.65/MH/01 (is this a record?) are fixed:
1349
1350 (i) An empty string was always treated as zero by the numeric comparison
1351 operators. This behaviour has been restored.
1352
1353 (ii) It is documented that the numeric comparison operators always treat
1354 their arguments as decimal numbers. This was broken in that numbers
1355 starting with 0 were being interpreted as octal.
1356
1357 While fixing these problems I realized that there was another issue that
1358 hadn't been noticed. Values of message_size_limit (both the global option
1359 and the transport option) were treated as octal if they started with 0.
1360 The documentation was vague. These values are now always treated as
1361 decimal, and I will make that clear in the documentation.

1375PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1376 child addresses, Exim now panics and dies. Previously, because the count
1377 is held in a short int, deliveries were likely to be lost. As such a
1378 large number of recipients for a single message is ridiculous
1379 (performance will be very, very poor), I have chosen to impose a limit
1380 rather than extend the field.

1396TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1405PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1406 callout verification, Exim cached a "reject" for the entire domain. This
1407 is correct for most verifications, but it is not correct for a recipient
1408 verification with use_sender or use_postmaster set, because in that case
1409 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1410 case of MAIL FROM:<> rejection from other early rejections (e.g.
1411 rejection of HELO). When verifying a recipient using a non-null MAIL
1412 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1413 Whatever the result of the callout, the value of the domain cache is
1414 left unchanged (for any other kind of callout, getting as far as trying
1415 RCPT means that the domain itself is ok).

1449PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1451 probably the interface on which it is arriving) and not to the outgoing
1452 callout (which could be using a different interface). This has been
1453 changed to use the value of the helo_data option from the smtp transport
1454 instead - this is what is used when a message is actually being sent. If
1455 there is no remote transport (possible with a router that sets up host
1456 addresses), $smtp_active_hostname is used.

7befa435 1459 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1460 (a) The code assumed that strncpy() returns a negative number on buffer
1461 overflow, which isn't the case. Replaced with Exim's string_format()
1462 function.
1463 (b) There were several signed/unsigned issues. I just did the minimum
1464 hacking in of casts. There is scope for a larger refactoring.
1465 (c) The code used strcasecmp() which is not a standard C function.
1466 Replaced with Exim's strcmpic() function.
1467 (d) The code set only $1; it now sets $auth1 as well.
1468 (e) A simple test gave the error "authentication client didn't specify
1469 service in request". It would seem that Dovecot has changed its
1470 interface. Fortunately there's a specification; I followed it and
1471 changed what the client sends and it appears to be working now.

1476PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1477 address A is aliased to B and C, where B exists and C does not. Without
1478 -v the output is "A verified" because verification stops after a
1479 successful redirection if more than one address is generated. However,
1480 with -v the child addresses are also verified. Exim was outputting "A
1481 failed to verify" and then showing the successful verification for C,
1482 with its parentage. It now outputs "B failed to verify", showing B's
1483 parentage before showing the successful verification of C.

1486 look up a TXT record in a specific list after matching in a combined

1488
322050c2
PH
1489PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1490 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1491 they consult the DNS. I had assumed they would set it the way they
1492 wanted; and indeed my experiments on Linux seem to show that in some
1493 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1494 To be on the safe side, however, I have now made the interface to
1495 host_find_byname() similar to host_find_bydns(), with an argument
1496 containing the DNS resolver options. The host_find_byname() function now
1497 sets these options at its start, just as host_find_bydns() does. The smtp
1498 transport options dns_qualify_single and dns_search_parents are passed to
1499 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1500 of host_find_byname() use the default settings of RES_DEFNAMES
1501 (qualify_single) but not RES_DNSRCH (search_parents).

1503PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1504 spool_read_header() do less string testing, by means of a preliminary
1505 switch on the second character of optional "-foo" lines. (This is
1506 overdue, caused by the large number of possibilities that now exist.
1507 Originally there were few.) While I was there, I also converted the
1508 str(n)cmp tests so they don't re-test the leading "-" and the first
1509 character, in the hope this might squeeze out yet more improvement.

PH
1511PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1512 flag allowing group syntax was set by the header_syntax check but not
1513 turned off, possible causing trouble later; (2) The flag was not being
1514 set at all for the header_verify test, causing "group"-style headers to
1515 be rejected. I have now set it in this case, and also caused header_
1516 verify to ignore an empty address taken from a group. While doing this, I
1517 came across some other cases where the code for allowing group syntax
1518 while scanning a header line wasn't quite right (mostly, not resetting
1519 the flag correctly in the right place). These bugs could have caused
1520 trouble for malformed header lines. I hope it is now all correct.

PH
1522PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1523 with the "reply" argument non-NULL. The code, however (which originally
1524 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1525 but it didn't always do it. This confused somebody who was copying the
1526 code for some other use. I have removed all the tests.

PH
1528PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1529 feature that was used to support insecure browsers during the U.S. crypto
1530 embargo. It requires special client support, and Exim is probably the
1531 only MTA that supported it -- and would never use it because real RSA is
1532 always available. This code has been removed, because it had the bad
1533 effect of slowing Exim down by computing (never used) parameters for the
1534 RSA_EXPORT functionality.

1539 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1540 if the connection is using TLS or if the remote IP is the same as the
1541 local IP, and the "valid-client-cert option" if a client certificate has
1542 been verified.

1573
1574PH/30 Exim was sometimes attempting to deliver messages that had suffered
1575 address errors (4xx response to RCPT) over the same connection as other
1576 messages routed to the same hosts. Such deliveries are always "forced",
1577 so retry times are not inspected. This resulted in far too many retries
1578 for the affected addresses. The effect occurred only when there were more
1579 hosts than the hosts_max_try setting in the smtp transport when it had
1580 the 4xx errors. Those hosts that it had tried were not added to the list
1581 of hosts for which the message was waiting, so if all were tried, there
1582 was no problem. Two fixes have been applied:
1583
1584 (i) If there are any address or message errors in an SMTP delivery, none
1585 of the hosts (tried or untried) are now added to the list of hosts
1586 for which the message is waiting, so the message should not be a
1587 candidate for sending over the same connection that was used for a
1588 successful delivery of some other message. This seems entirely
1589 reasonable: after all the message is NOT "waiting for some host".
1590 This is so "obvious" that I'm not sure why it wasn't done
1591 previously. Hope I haven't missed anything, but it can't do any
1592 harm, as the worst effect is to miss an optimization.
1593
1594 (ii) If, despite (i), such a delivery is accidentally attempted, the
1595 routing retry time is respected, so at least it doesn't keep
1596 hammering the server.

1612 written to the panic log as well as the main log, but it isn't really

PH
1617PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1618 runs only) independently of the message's sender address. This meant
1619 that, if the 4xx error was in fact related to the sender, a different
1620 message to the same recipient with a different sender could confuse
1621 things. In particualar, this can happen when sending to a greylisting
1622 server, but other circumstances could also provoke similar problems.
1623 I have changed the default so that the retry time for these errors is now
1624 based a combination of the sender and recipient addresses. This change
1625 can be overridden by setting address_retry_include_sender=false in the
1626 smtp transport.

1900 554 error is used if errno is still zero or contains ENOENT (which occurs

1985 syntactically invalid From: or Reply-to: line, and a filter used this to
1986 generate an autoreply, and therefore failed to obtain an address for the
1987 autoreply, Exim could try to deliver to a non-existent relative file
1988 name, causing unrelated and misleading errors. What now happens is that
1989 it logs this as a hard delivery error, but does not attempt to create a

2007 non-existent - all you got was a failure to exec. I have made two
2008 changes:
2009
2010 (a) Failures to set uid/gid, the current directory, or a process leader
2011 in a subprocess such as that created by queryprogram now generate
2012 suitable debugging ouput when -d is set.

2021PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2022 additional section of a DNS packet that returns MX or SRV records.
2023 Instead, it always explicitly searches for A/AAAA records. This avoids
2024 major problems that occur when a DNS server includes only records of one
2025 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2026 fixed another bug: if SRV records were looked up and the corresponding
2027 address records were *not* found in the additional section, the port
2028 values from the SRV records were lost.

PH
2038PH/19 When calculating a retry time, Exim used to measure the "time since
2039 failure" by looking at the "first failed" field in the retry record. Now
2040 it does not use this if it is later than than the arrival time of the
2041 message. Instead it uses the arrival time. This makes for better
2042 behaviour in cases where some deliveries succeed, thus re-setting the
2043 "first failed" field. An example is a quota failure for a huge message
2044 when small messages continue to be delivered. Without this change, the
2045 "time since failure" will always be short, possible causing more frequent
2046 delivery attempts for the huge message than are intended.

PH
2143PH/42 The content-scanning code uses fopen() to create files in which to put
2144 message data. Previously it was not paying any attention to the mode of
2145 the files. Exim runs with umask(0) because the rest of the code creates
2146 files with open(), and sets the required mode explicitly. Thus, these
2147 files were ending up world-writeable. This was not a big issue, because,
2148 being within the spool directory, they were not world-accessible. I have
2149 created a function called modefopen, which takes an additional mode
2150 argument. It sets umask(777), creates the file, chmods it to the required
2151 mode, then resets the umask. All the relevant calls to fopen() in the
2152 content scanning code have been changed to use this function.

2164 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2187PH/52 Two bugs concerned with error handling when the smtp transport is
2188 used in LMTP mode:
2189
2190 (i) Exim was not creating retry information for temporary errors given
2191 for individual recipients after the DATA command when the smtp transport
2192 was used in LMTP mode. This meant that they could be retried too
2193 frequently, and not timed out correctly.
2194
2195 (ii) Exim was setting the flag that allows error details to be returned
2196 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2197 recipients that were returned after the DATA command.
2198
2199PH/53 This is related to PH/52, but is more general: for any failing address,
2200 when detailed error information was permitted to be returned to the
2201 sender, but the error was temporary, then after the final timeout, only
2202 "retry timeout exceeded" was returned. Now it returns the full error as

2273PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2274 function verify_get_ident() calls ip_connect() to connect a socket, but
2275 if the "connect()" function timed out, ip_connect() used to close the
2276 socket. However, verify_get_ident() also closes the socket later, and in
2277 between Exim writes to the log, which may get opened at this point. When
2278 the socket was closed in ip_connect(), the log could get the same file
2279 descriptor number as the socket. This naturally causes chaos. The fix is
2280 not to close the socket in ip_connect(); the socket should be closed by
2281 the function that creates it. There was only one place in the code where
2282 this was missing, in the iplookup router, which I don't think anybody now
2283 uses, but I've fixed it anyway.

2309
2310 (3) Reset the variables that are obtained from the first argument of
2311 ${prvscheck and used in the second argument before leaving the code,
2312 because their memory is reclaimed, so using them afterwards may do
2313 silly things.
2314
2315 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2316 one (it's much easier than Tom thought :-).

2340 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2341 not being looked up in the rDNS to get a host name, Exim was showing the
2342 IP address twice in Received: lines, even though the IP addresses were
2343 identical. For example:
2344
2345 Received: from [1.2.3.4] (helo=[1.2.3.4])
2346
2347 However, if the real host name was known, it was omitting the HELO data

2349 doesn't show the same IP address twice.

2375PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2376 Electronic Mail") by including:
2377
2378 Auto-submitted: auto-generated
2379
2380 in the messages that it generates (bounce messages and others, such as
2381 warnings). In the case of bounce messages for non-SMTP mesages, there was
2382 also a typo: it was using "Auto_submitted" (underscore instead of
2383 hyphen). Since every message generated by Exim is necessarily in response
2384 to another message, thes have all been changed to:
2385
2386 Auto-Submitted: auto-replied
2387
2388 in accordance with these statements in the RFC:
2389
2390 The auto-replied keyword:
2391
2392 - SHOULD be used on messages sent in direct response to another
2393 message by an automatic process,
2394
2395 - MUST NOT be used on manually-generated messages,
2396
2397 - MAY be used on Delivery Status Notifications (DSNs) and Message
2398 Disposition Notifications (MDNs),
2399
2400 - MUST NOT be used on messages generated by automatic or periodic
2401 processes, except for messages which are automatic responses to
2402 other messages.

2438PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2439 canonical form (as documented). However, after a host name lookup from
2440 the IP address, check_host() was doing a simple string comparison with
2441 addresses acquired from the DNS when checking that the found name did
2442 have the original IP as one of its addresses. Since any found IPv6
2443 addresses are likely to be in abbreviated form, the comparison could
2444 fail. Luckily, there already exists a function for doing the comparison
2445 by converting both addresses to binary, so now that is used instead of
2446 the text comparison.
2447
96776534
PH
2448PH/20 There was another similar case to PH/19, when a complete host name was

2746 preserve the sysexits.h value, by assumimg that macro definitions were

2830 the logs files are, rather than using the compiled in default. In our
2831 case the guess is not the same as the compiled default, so the script
2832 suddenly stopped working when I started to use syslog. The patch checks
2833 to see if log_file_path is "". If so, it attempts to read it from exim

2894 read the rcpt_include_affixes from the non-existent transport. Now it

2963
2964PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2965 that changes the way the GnuTLS parameters are stored in the cache file.
2966 The new format can be generated externally. For backward compatibility,
2967 if the data in the cache doesn't make sense, Exim assumes it has read an
2968 old-format file, and it generates new data and writes a new file. This
2969 means that you can't go back to an older release without removing the
2970 file.
2971
2972PH/03 A redirect router that has both "unseen" and "one_time" set does not
2973 work if there are any delivery delays because "one_time" forces the
2974 parent to be marked "delivered", so its unseen clone is never tried
2975 again. For this reason, Exim now forbids the simultaneous setting of
2976 these two options.
2977
2978PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2979 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2980 entry if you want to know the details. The fix, however, neglected to
2981 consider the case when local delivery batching is involved. The test for
2982 "previously delivered" was not happening when checking to see if an
2983 address could be batched with a previous (undelivered) one; under
2984 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2985 address.

2987PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

2990PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2991 header_syntax) but Exim was just ignoring anything given after a slash.
2992 In particular, this caused confusion with an attempt to use "verify =
2993 reverse_host_lookup/defer_ok". An error is now given when options are
2994 supplied for verify items that do not have them. (Maybe reverse_host_
2995 lookup should have a defer_ok option, but that's a different point.)
2996
2997PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3048 file, it does so in a subprocess that runs as exim:exim so as to get the
3049 ownership right at creation (otherwise, other Exim processes might see
3050 the file with the wrong ownership). There was no test for failure of this
3051 fork() call, which would lead to the process getting stuck as it waited
3052 for a non-existent subprocess. Forks do occasionally fail when resources
3053 run out. I reviewed all the other calls to fork(); they all seem to check
3054 for failure.

3059 the result was a log entry for a synchronization error with an empty
3060 string after "input=" when read() returned zero. If read() returned -1

PH
3073PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3074 hadn't been configured. The fix is from Juergen Kreileder, who
3075 understands it better than I do:
3076
3077 "Here's what I see happening with three configured cyrus_sasl
3078 authenticators configured (plain, login, cram-md5):
3079
3080 On startup auth_cyrus_sasl_init() gets called for each of these.
3081 This means three calls to sasl_listmech() without a specified mech_list.
3082 => SASL tests which mechs of all available mechs actually work
3083 => three warnings about OTP not working
3084 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3085
3086 With the patch, sasl_listmech() also gets called three times. But now
3087 SASL's mech_list option is set to the server_mech specified in the the
3088 authenticator. Or in other words, the answer from sasl_listmech()
3089 gets limited to just the mech you're testing for (which is different
3090 for each call.)
3091 => the return list contains just 'plain' or 'login', 'cram-md5' or
3092 nothing depending on the value of ob->server_mech.
3093
3094 I've just tested the patch: Authentication still works fine,

3166 behaviour dependent on the order in which the addresses were given.
3167
3168 I have moved the duplicate checking until after the routing is complete.
3169 Exim scans the addresses that are assigned to local and remote
3170 transports, and removes any duplicates. This means that more work will be
3171 done, as duplicates will always all be routed, but duplicates are
3172 presumably rare, so I don't expect this is of any significance.
3173
3174 For deliveries to pipes, files, and autoreplies, the duplicate checking
3175 still happens during the routing process, since they are not going to be
3176 routed further.

3178PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3179 It corrects a timeout issue with spamd. This is Ian's comment: "The
3180 background is that sometimes spamd either never reads data from a
3181 connection it has accepted, or it never writes response data. The exiscan
3182 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3183 blindly assumes that writes won't block so it may never time out."

3197PH/42 Exim no longer gives details of delivery errors for specific addresses in
3198 bounce and delay warning messages, except in certain special cases, which
3199 are as follows:
3200
3201 (a) An SMTP error message from a remote host;
3202 (b) A message specified in a :fail: redirection;
3203 (c) A message specified in a "fail" command in a system filter;
3204 (d) A message specified in a FAIL return from the queryprogram router;
3205 (e) A message specified by the cannot_route_message router option.
3206
3207 In these cases only, Exim does include the error details in bounce and
3208 warning messages. There are also a few cases where bland messages such
3209 as "unrouteable address" or "local delivery error" are given.

3217PH/45 In a pipe transport, although a timeout while waiting for the pipe
3218 process to complete was treated as a delivery failure, a timeout while
3219 writing the message to the pipe was logged, but erroneously treated as a
3220 successful delivery. Such timeouts include transport filter timeouts. For
3221 consistency with the overall process timeout, these timeouts are now
3222 treated as errors, giving rise to delivery failures by default. However,
3223 there is now a new Boolean option for the pipe transport called
3224 timeout_defer, which, if set TRUE, converts the failures into defers for
3225 both kinds of timeout. A transport filter timeout is now identified in
3226 the log output.

3235A note about Exim versions 4.44 and 4.50
3236----------------------------------------
3237
3238Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3239changes of various kinds. As a consequence, a big documentation update was
3240needed. This delayed the release for rather longer than seemed good, especially
3241in the light of a couple of (minor) security issues. Therefore, the changes
3242that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3243release. So 4.44 and 4.50 are in effect two different branches that both start
3244from 4.43.
3245
3246I have left the 4.50 change log unchanged; it contains all the changes since
32474.43. The change log for 4.44 is below; many of its items are identical to
3248those for 4.50. This seems to be the most sensible way to preserve the
3249historical information.

3255 1. Minor wording change to the doc/README.SIEVE file.

3267 5. There are several places where Exim runs a non-Exim command in a
3268 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3269 was being done only for the command run by the queryprogram router. It is
3270 now done for all such subprocesses. The other cases are: ${run, transport
3271 filters, and the commands run by the lmtp and pipe transports.

3273 6. Added CONFIGURE_GROUP build-time option.
3274
3275 7. Some older OS have a limit of 256 on the maximum number of file
3276 descriptors. Exim was using setrlimit() to set 1000 as a large value
3277 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3278 systems. I've change it so that if it can't get 1000, it tries for 256.

3280 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3281 was an oversight, and furthermore, ever since the addition of extra
3282 controls (e.g. 4.43/32), the checks on when to allow different forms of
3283 "control" were broken. There should now be diagnostics for all cases when a
3284 control that does not make sense is encountered.

332522. $host_address is now set to the target address during the checking of
3326 ignore_target_hosts.
3327
332823. When checking ignore_target_hosts for an ipliteral router, no host name was
3329 being passed; this would have caused $sender_host_name to have been used if
3330 matching the list had actually called for a host name (not very likely,
3331 since this list is usually IP addresses). A host name is now passed as
3332 "[x.x.x.x]".

PH
333424. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3335 code that specifies a non-restarting handler (typically sigaction() in
3336 modern systems) in an attempt to fix a rare and obscure crash bug.
3337
333825. Narrowed the window for a race in the daemon that could cause it to ignore
3339 SIGCHLD signals. This is not a major problem, because they are used only to
3340 wake it up if nothing else does.

334226. A malformed maildirsize file could cause Exim to calculate negative values
3343 for the mailbox size or file count. Odd effects could occur as a result.
3344 The maildirsize information is now recalculated if the size or filecount
3345 end up negative.

335229. In an address list, if the pattern was not a regular expression, an empty
3353 subject address (from a bounce message) matched only if the pattern was an
3354 empty string. Non-empty patterns were not even tested. This was the wrong
3355 because it is perfectly reasonable to use an empty address as part of a
3356 database query. An empty address is now tested by patterns that are
3357 lookups. However, all the other forms of pattern expect the subject to
3358 contain a local part and a domain, and therefore, for them, an empty
3359 address still always fails if the pattern is not itself empty.

336130. Exim went into a mad DNS loop when attempting to do a callout where the
3362 host was specified on an smtp transport, and looking it up yielded more
3363 than one IP address.

336531. Re-factored the code for checking spool and log partition space into a
3366 function that finds that data and another that does the check. The former
3367 is then used to implement four new variables: $spool_space, $log_space,
3368 $spool_inodes, and $log_inodes.

337032. The RFC2047 encoding function was originally intended for short strings
3371 such as real names; it was not keeping to the 75-character limit for
3372 encoded words that the RFC imposes. It now respects the limit, and
3373 generates multiple encoded words if necessary. To be on the safe side, I
3374 have increased the buffer size for the ${rfc2047: expansion operator from
3375 1024 to 2048 bytes.

337733. It is now permitted to omit both strings after an "if" condition; if the
3378 condition is true, the result is "true". As before, when the second string
3379 is omitted, a false condition yields an empty string. This makes it less
3380 cumbersome to write custom ACL and router conditions.
3381

PH
338234. Failure to deliver a bounce message always caused it to be frozen, even if
3383 there was an errors_to setting on the router. The errors_to setting is now
