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
326cdc37
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.

151PP/14 Fix OCSP reinitialisation in SNI handling for Exim/TLS as server.
152 Bug spotted by Jeremy Harris; was flawed since initial commit.
153 Would have resulted in OCSP responses post-SNI triggering an Exim
154 NULL dereference and crash.

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".

PP
183PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
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.
188
0fbd9bff
PP
189PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it
190 clearer that Exim is using the DO (DNSSEC OK) EDNS0 resolver flag,
191 not performing validation itself.

PP
363PP/33 Added tls_dh_max_bits option, defaulting to current hard-coded limit

365 Janne Snabb (who went above and beyond: thank you).
366
367PP/34 Validate tls_require_ciphers on startup, since debugging an invalid
368 string otherwise requires a connection and a bunch more work and it's

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

412 purpose logging code to do this, but several functions it calls are
413 not safe for signals.
414
415 The new output code in the SIGUSR1 handler is specific to the process
416 log, and simple enough that it's easy to inspect for signal safety.
417 Removing some special cases also simplifies the general logging code.
418 Removing the spurious timestamps from the process log simplifies
419 exiwhat.

421TF/04 Improved ratelimit ACL condition.
422
423 The /noupdate option has been deprecated in favour of /readonly which
424 has clearer semantics. The /leaky, /strict, and /readonly update modes
425 are mutually exclusive. The update mode is no longer included in the
426 database key; it just determines when the database is updated. (This
427 means that when you upgrde Exim will forget old rate measurements.)
428
429 Exim now checks that the per_* options are used with an update mode that
430 makes sense for the current ACL. For example, when Exim is processing a
431 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
432 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
433 must specify per_mail/readonly. If you omit the update mode it defaults to
434 /leaky where that makes sense (as before) or /readonly where required.
435
436 The /noupdate option is now undocumented but still supported for
437 backwards compatibility. It is equivalent to /readonly except that in
438 ACLs where /readonly is required you may specify /leaky/noupdate or
439 /strict/noupdate which are treated the same as /readonly.
440
441 A useful new feature is the /count= option. This is a generalization
442 of the per_byte option, so that you can measure the throughput of other
443 aggregate values. For example, the per_byte option is now equivalent
444 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
445
446 The per_rcpt option has been generalized using the /count= mechanism
447 (though it's more complicated than the per_byte equivalence). When it is
448 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
449 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
450 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
451 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
452 Note that using per_rcpt with a non-readonly update mode in more than
453 one ACL will cause the recipients to be double-counted. (The per_mail
454 and per_byte options don't have this problem.)
455
456 The handling of very low rates has changed slightly. If the computed rate
457 is less than the event's count (usually one) then this event is the first
458 after a long gap. In this case the rate is set to the same as this event's
459 count, so that the first message of a spam run is counted properly.
460
461 The major new feature is a mechanism for counting the rate of unique
462 events. The new per_addr option counts the number of different
463 recipients that someone has sent messages to in the last time period. It
464 behaves like per_rcpt if all the recipient addresses are different, but
465 duplicate recipient addresses do not increase the measured rate. Like
466 the /count= option this is a general mechanism, so the per_addr option
467 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
468 example, measure the rate that a client uses different sender addresses
469 with the options per_mail/unique=$sender_address. There are further
470 details in the main documentation.

1021 were called 'true' and it seems that C99 defines that as a reserved

1023 not include C99-style headers which use bools without triggering

1042PH/01 Another patch from the Sieve maintainer.
1043
6a3bceb1
PH
1044PH/02 When an IPv6 address is converted to a string for single-key lookup
1045 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1046 dots are used instead of colons so that keys in lsearch files need not
1047 contain colons. This was done some time before quoting was made available
1048 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1049 (notated using the quote facility) so as to distinguish them from IPv4
1050 keys. This meant that lookups for IP addresses in host lists did not work
1051 for iplsearch lookups.
1052
1053 This has been fixed by arranging for IPv6 addresses to be expressed with
1054 colons if the lookup type is iplsearch. This is not incompatible, because
1055 previously such lookups could never work.
1056
1057 The situation is now rather anomolous, since one *can* have colons in
1058 ordinary lsearch keys. However, making the change in all cases is
1059 incompatible and would probably break a number of configurations.

1064MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1065 conversion specification without a maximum field width, thereby enabling
1066 a rogue spamd server to cause a buffer overflow. While nobody in their
1067 right mind would setup Exim to query an untrusted spamd server, an
1068 attacker that gains access to a server running spamd could potentially
1069 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1074MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1075 a directory entry by the name of the lookup key. Previously, if a
1076 symlink pointed to a non-existing file or a file in a directory that
1077 Exim lacked permissions to read, a lookup for a key matching that
1078 symlink would fail. Now it is enough that a matching directory entry
1079 exists, symlink or not. (Bugzilla 503.)

1262PH/29 SMTP synchronization checks are implemented when a command is read -
1263 there is a check that no more input is waiting when there shouldn't be
1264 any. However, for some commands, a delay in an ACL can mean that it is
1265 some time before the response is written. In this time, more input might
1266 arrive, invalidly. So now there are extra checks after an ACL has run for
1267 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1268 pipelining has not been advertised.

PH
1342 the response to the final '.' that terminates a message, but only in the
1343 case where the client has not sent further data following the '.'
1344 (unfortunately, this is allowed). However, in many cases there won't be
1345 any further data because there won't be any more messages to send. A call
1346 to select() can be used: if it shows that the input is "ready", there is
1347 either input waiting, or the socket has been closed. An attempt to read
1348 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1349 would have sent an OK response which the client would never have see.

1360PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1361 fixed by 4.65/MH/01 (is this a record?) are fixed:
1362
1363 (i) An empty string was always treated as zero by the numeric comparison
1364 operators. This behaviour has been restored.
1365
1366 (ii) It is documented that the numeric comparison operators always treat
1367 their arguments as decimal numbers. This was broken in that numbers
1368 starting with 0 were being interpreted as octal.
1369
1370 While fixing these problems I realized that there was another issue that
1371 hadn't been noticed. Values of message_size_limit (both the global option
1372 and the transport option) were treated as octal if they started with 0.
1373 The documentation was vague. These values are now always treated as
1374 decimal, and I will make that clear in the documentation.

1388PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

1390 is held in a short int, deliveries were likely to be lost. As such a
1391 large number of recipients for a single message is ridiculous
1392 (performance will be very, very poor), I have chosen to impose a limit
1393 rather than extend the field.

1400 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
1418PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1419 callout verification, Exim cached a "reject" for the entire domain. This
1420 is correct for most verifications, but it is not correct for a recipient
1421 verification with use_sender or use_postmaster set, because in that case
1422 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1423 case of MAIL FROM:<> rejection from other early rejections (e.g.
1424 rejection of HELO). When verifying a recipient using a non-null MAIL
1425 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1426 Whatever the result of the callout, the value of the domain cache is
1427 left unchanged (for any other kind of callout, getting as far as trying
1428 RCPT means that the domain itself is ok).

1462PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1464 probably the interface on which it is arriving) and not to the outgoing
1465 callout (which could be using a different interface). This has been
1466 changed to use the value of the helo_data option from the smtp transport
1467 instead - this is what is used when a message is actually being sent. If
1468 there is no remote transport (possible with a router that sets up host
1469 addresses), $smtp_active_hostname is used.

7befa435 1472 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1473 (a) The code assumed that strncpy() returns a negative number on buffer
1474 overflow, which isn't the case. Replaced with Exim's string_format()
1475 function.
1476 (b) There were several signed/unsigned issues. I just did the minimum
1477 hacking in of casts. There is scope for a larger refactoring.
1478 (c) The code used strcasecmp() which is not a standard C function.
1479 Replaced with Exim's strcmpic() function.
1480 (d) The code set only $1; it now sets $auth1 as well.
1481 (e) A simple test gave the error "authentication client didn't specify
1482 service in request". It would seem that Dovecot has changed its
1483 interface. Fortunately there's a specification; I followed it and
1484 changed what the client sends and it appears to be working now.

1490 address A is aliased to B and C, where B exists and C does not. Without
1491 -v the output is "A verified" because verification stops after a
1492 successful redirection if more than one address is generated. However,
1493 with -v the child addresses are also verified. Exim was outputting "A
1494 failed to verify" and then showing the successful verification for C,
1495 with its parentage. It now outputs "B failed to verify", showing B's
1496 parentage before showing the successful verification of C.

1501
322050c2
PH
1502PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1503 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1504 they consult the DNS. I had assumed they would set it the way they
1505 wanted; and indeed my experiments on Linux seem to show that in some
1506 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1507 To be on the safe side, however, I have now made the interface to
1508 host_find_byname() similar to host_find_bydns(), with an argument
1509 containing the DNS resolver options. The host_find_byname() function now
1510 sets these options at its start, just as host_find_bydns() does. The smtp
1511 transport options dns_qualify_single and dns_search_parents are passed to
1512 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1513 of host_find_byname() use the default settings of RES_DEFNAMES
1514 (qualify_single) but not RES_DNSRCH (search_parents).

1516PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1517 spool_read_header() do less string testing, by means of a preliminary
1518 switch on the second character of optional "-foo" lines. (This is
1519 overdue, caused by the large number of possibilities that now exist.
1520 Originally there were few.) While I was there, I also converted the
1521 str(n)cmp tests so they don't re-test the leading "-" and the first
1522 character, in the hope this might squeeze out yet more improvement.

PH
1524PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1525 flag allowing group syntax was set by the header_syntax check but not
1526 turned off, possible causing trouble later; (2) The flag was not being
1527 set at all for the header_verify test, causing "group"-style headers to
1528 be rejected. I have now set it in this case, and also caused header_
1529 verify to ignore an empty address taken from a group. While doing this, I
1530 came across some other cases where the code for allowing group syntax
1531 while scanning a header line wasn't quite right (mostly, not resetting
1532 the flag correctly in the right place). These bugs could have caused
1533 trouble for malformed header lines. I hope it is now all correct.

PH
1535PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1538 but it didn't always do it. This confused somebody who was copying the
1539 code for some other use. I have removed all the tests.

PH
1541PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1542 feature that was used to support insecure browsers during the U.S. crypto
1543 embargo. It requires special client support, and Exim is probably the
1544 only MTA that supported it -- and would never use it because real RSA is
1545 always available. This code has been removed, because it had the bad
1546 effect of slowing Exim down by computing (never used) parameters for the
1547 RSA_EXPORT functionality.

1553 if the connection is using TLS or if the remote IP is the same as the
1554 local IP, and the "valid-client-cert option" if a client certificate has
1555 been verified.

1587PH/30 Exim was sometimes attempting to deliver messages that had suffered
1588 address errors (4xx response to RCPT) over the same connection as other
1589 messages routed to the same hosts. Such deliveries are always "forced",
1590 so retry times are not inspected. This resulted in far too many retries
1591 for the affected addresses. The effect occurred only when there were more
1592 hosts than the hosts_max_try setting in the smtp transport when it had
1593 the 4xx errors. Those hosts that it had tried were not added to the list
1594 of hosts for which the message was waiting, so if all were tried, there
1595 was no problem. Two fixes have been applied:
1596
1597 (i) If there are any address or message errors in an SMTP delivery, none
1598 of the hosts (tried or untried) are now added to the list of hosts
1599 for which the message is waiting, so the message should not be a
1600 candidate for sending over the same connection that was used for a
1601 successful delivery of some other message. This seems entirely
1602 reasonable: after all the message is NOT "waiting for some host".
1603 This is so "obvious" that I'm not sure why it wasn't done
1604 previously. Hope I haven't missed anything, but it can't do any
1605 harm, as the worst effect is to miss an optimization.
1606
1607 (ii) If, despite (i), such a delivery is accidentally attempted, the
1608 routing retry time is respected, so at least it doesn't keep
1609 hammering the server.

1624PH/35 The error "getsockname() failed: connection reset by peer" was being
1625 written to the panic log as well as the main log, but it isn't really

1627 removed the panic log writing for the ECONNRESET error when getsockname()
1628 fails.

48c7f9e2
PH
1630PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1631 runs only) independently of the message's sender address. This meant
1632 that, if the 4xx error was in fact related to the sender, a different
1633 message to the same recipient with a different sender could confuse
1634 things. In particualar, this can happen when sending to a greylisting
1635 server, but other circumstances could also provoke similar problems.
1636 I have changed the default so that the retry time for these errors is now
1637 based a combination of the sender and recipient addresses. This change
1638 can be overridden by setting address_retry_include_sender=false in the
1639 smtp transport.

2000 autoreply, Exim could try to deliver to a non-existent relative file

2034PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2035 additional section of a DNS packet that returns MX or SRV records.
2036 Instead, it always explicitly searches for A/AAAA records. This avoids
2037 major problems that occur when a DNS server includes only records of one
2038 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2039 fixed another bug: if SRV records were looked up and the corresponding
2040 address records were *not* found in the additional section, the port
2041 values from the SRV records were lost.

PH
2051PH/19 When calculating a retry time, Exim used to measure the "time since
2052 failure" by looking at the "first failed" field in the retry record. Now
2053 it does not use this if it is later than than the arrival time of the
2054 message. Instead it uses the arrival time. This makes for better
2055 behaviour in cases where some deliveries succeed, thus re-setting the
2056 "first failed" field. An example is a quota failure for a huge message
2057 when small messages continue to be delivered. Without this change, the
2058 "time since failure" will always be short, possible causing more frequent
2059 delivery attempts for the huge message than are intended.

PH
2156PH/42 The content-scanning code uses fopen() to create files in which to put
2157 message data. Previously it was not paying any attention to the mode of
2158 the files. Exim runs with umask(0) because the rest of the code creates
2159 files with open(), and sets the required mode explicitly. Thus, these
2160 files were ending up world-writeable. This was not a big issue, because,
2161 being within the spool directory, they were not world-accessible. I have
2162 created a function called modefopen, which takes an additional mode
2163 argument. It sets umask(777), creates the file, chmods it to the required
2164 mode, then resets the umask. All the relevant calls to fopen() in the
2165 content scanning code have been changed to use this function.

2202
2203 (i) Exim was not creating retry information for temporary errors given
2204 for individual recipients after the DATA command when the smtp transport
2205 was used in LMTP mode. This meant that they could be retried too
2206 frequently, and not timed out correctly.
2207
2208 (ii) Exim was setting the flag that allows error details to be returned
2209 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2210 recipients that were returned after the DATA command.
2211
2212PH/53 This is related to PH/52, but is more general: for any failing address,
2213 when detailed error information was permitted to be returned to the
2214 sender, but the error was temporary, then after the final timeout, only

2286PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2287 function verify_get_ident() calls ip_connect() to connect a socket, but
2288 if the "connect()" function timed out, ip_connect() used to close the
2289 socket. However, verify_get_ident() also closes the socket later, and in
2290 between Exim writes to the log, which may get opened at this point. When
2291 the socket was closed in ip_connect(), the log could get the same file
2292 descriptor number as the socket. This naturally causes chaos. The fix is
2293 not to close the socket in ip_connect(); the socket should be closed by
2294 the function that creates it. There was only one place in the code where
2295 this was missing, in the iplookup router, which I don't think anybody now
2296 uses, but I've fixed it anyway.

2354 not being looked up in the rDNS to get a host name, Exim was showing the
2355 IP address twice in Received: lines, even though the IP addresses were
2356 identical. For example:
2357
2358 Received: from [1.2.3.4] (helo=[1.2.3.4])
2359

2388PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2389 Electronic Mail") by including:
2390
2391 Auto-submitted: auto-generated
2392
2393 in the messages that it generates (bounce messages and others, such as
2394 warnings). In the case of bounce messages for non-SMTP mesages, there was
2395 also a typo: it was using "Auto_submitted" (underscore instead of
2396 hyphen). Since every message generated by Exim is necessarily in response
2397 to another message, thes have all been changed to:
2398
2399 Auto-Submitted: auto-replied
2400
2401 in accordance with these statements in the RFC:
2402
2403 The auto-replied keyword:
2404
2405 - SHOULD be used on messages sent in direct response to another
2406 message by an automatic process,
2407
2408 - MUST NOT be used on manually-generated messages,
2409
2410 - MAY be used on Delivery Status Notifications (DSNs) and Message
2411 Disposition Notifications (MDNs),
2412
2413 - MUST NOT be used on messages generated by automatic or periodic
2414 processes, except for messages which are automatic responses to
2415 other messages.

2451PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2452 canonical form (as documented). However, after a host name lookup from
2453 the IP address, check_host() was doing a simple string comparison with
2454 addresses acquired from the DNS when checking that the found name did
2455 have the original IP as one of its addresses. Since any found IPv6
2456 addresses are likely to be in abbreviated form, the comparison could
2457 fail. Luckily, there already exists a function for doing the comparison
2458 by converting both addresses to binary, so now that is used instead of
2459 the text comparison.

PH
2461PH/20 There was another similar case to PH/19, when a complete host name was

2759 preserve the sysexits.h value, by assumimg that macro definitions were

2766 This seems wrong - if the receiver was accepting one byte at a time it
2767 would take for ever. The timeout is now adjusted when this happens. It
2768 doesn't have to be particularly precise.

2844 case the guess is not the same as the compiled default, so the script
2845 suddenly stopped working when I started to use syslog. The patch checks

2976
2977PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2978 that changes the way the GnuTLS parameters are stored in the cache file.
2979 The new format can be generated externally. For backward compatibility,
2980 if the data in the cache doesn't make sense, Exim assumes it has read an
2981 old-format file, and it generates new data and writes a new file. This
2982 means that you can't go back to an older release without removing the
2983 file.
2984
2985PH/03 A redirect router that has both "unseen" and "one_time" set does not
2986 work if there are any delivery delays because "one_time" forces the
2987 parent to be marked "delivered", so its unseen clone is never tried
2988 again. For this reason, Exim now forbids the simultaneous setting of
2989 these two options.
2990
2991PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2992 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2993 entry if you want to know the details. The fix, however, neglected to
2994 consider the case when local delivery batching is involved. The test for
2995 "previously delivered" was not happening when checking to see if an
2996 address could be batched with a previous (undelivered) one; under
2997 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2998 address.

3000PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3003PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3004 header_syntax) but Exim was just ignoring anything given after a slash.
3005 In particular, this caused confusion with an attempt to use "verify =
3006 reverse_host_lookup/defer_ok". An error is now given when options are
3007 supplied for verify items that do not have them. (Maybe reverse_host_
3008 lookup should have a defer_ok option, but that's a different point.)

3010PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3062 ownership right at creation (otherwise, other Exim processes might see
3063 the file with the wrong ownership). There was no test for failure of this
3064 fork() call, which would lead to the process getting stuck as it waited
3065 for a non-existent subprocess. Forks do occasionally fail when resources
3066 run out. I reviewed all the other calls to fork(); they all seem to check

3072 the result was a log entry for a synchronization error with an empty
3073 string after "input=" when read() returned zero. If read() returned -1

3086PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3087 hadn't been configured. The fix is from Juergen Kreileder, who
3088 understands it better than I do:
3089
3090 "Here's what I see happening with three configured cyrus_sasl
3091 authenticators configured (plain, login, cram-md5):
3092
3093 On startup auth_cyrus_sasl_init() gets called for each of these.
3094 This means three calls to sasl_listmech() without a specified mech_list.
3095 => SASL tests which mechs of all available mechs actually work
3096 => three warnings about OTP not working
3097 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3098
3099 With the patch, sasl_listmech() also gets called three times. But now
3100 SASL's mech_list option is set to the server_mech specified in the the
3101 authenticator. Or in other words, the answer from sasl_listmech()
3102 gets limited to just the mech you're testing for (which is different
3103 for each call.)
3104 => the return list contains just 'plain' or 'login', 'cram-md5' or
3105 nothing depending on the value of ob->server_mech.
3106
3107 I've just tested the patch: Authentication still works fine,

3164 the uid or gid is negative. A case of a negative gid caused this to be
3165 noticed. The fix allows for either to be negative.

3173PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3174 the grounds that routing the same address twice would always produce the
3175 same answer. This might have been true once, but it is certainly no
3176 longer true now. Routing a child address may depend on the previous
3177 routing that produced that child. Some complicated redirection strategies
3178 went wrong when messages had multiple recipients, and made Exim's
3179 behaviour dependent on the order in which the addresses were given.
3180
3181 I have moved the duplicate checking until after the routing is complete.
3182 Exim scans the addresses that are assigned to local and remote
3183 transports, and removes any duplicates. This means that more work will be
3184 done, as duplicates will always all be routed, but duplicates are
3185 presumably rare, so I don't expect this is of any significance.
3186
3187 For deliveries to pipes, files, and autoreplies, the duplicate checking
3188 still happens during the routing process, since they are not going to be
3189 routed further.

3191PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3192 It corrects a timeout issue with spamd. This is Ian's comment: "The
3193 background is that sometimes spamd either never reads data from a
3194 connection it has accepted, or it never writes response data. The exiscan
3195 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3196 blindly assumes that writes won't block so it may never time out."

3210PH/42 Exim no longer gives details of delivery errors for specific addresses in
3211 bounce and delay warning messages, except in certain special cases, which
3212 are as follows:
3213
3214 (a) An SMTP error message from a remote host;
3215 (b) A message specified in a :fail: redirection;
3216 (c) A message specified in a "fail" command in a system filter;
3217 (d) A message specified in a FAIL return from the queryprogram router;
3218 (e) A message specified by the cannot_route_message router option.
3219
3220 In these cases only, Exim does include the error details in bounce and
3221 warning messages. There are also a few cases where bland messages such
3222 as "unrouteable address" or "local delivery error" are given.

3230PH/45 In a pipe transport, although a timeout while waiting for the pipe
3231 process to complete was treated as a delivery failure, a timeout while
3232 writing the message to the pipe was logged, but erroneously treated as a
3233 successful delivery. Such timeouts include transport filter timeouts. For
3234 consistency with the overall process timeout, these timeouts are now
3235 treated as errors, giving rise to delivery failures by default. However,
3236 there is now a new Boolean option for the pipe transport called
3237 timeout_defer, which, if set TRUE, converts the failures into defers for
3238 both kinds of timeout. A transport filter timeout is now identified in
3239 the log output.

3248A note about Exim versions 4.44 and 4.50
3249----------------------------------------
3250
3251Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3252changes of various kinds. As a consequence, a big documentation update was
3253needed. This delayed the release for rather longer than seemed good, especially
3254in the light of a couple of (minor) security issues. Therefore, the changes
3255that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3256release. So 4.44 and 4.50 are in effect two different branches that both start
3257from 4.43.
3258
3259I have left the 4.50 change log unchanged; it contains all the changes since
32604.43. The change log for 4.44 is below; many of its items are identical to
3261those for 4.50. This seems to be the most sensible way to preserve the
3262historical information.

3280 5. There are several places where Exim runs a non-Exim command in a
3281 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3282 was being done only for the command run by the queryprogram router. It is
3283 now done for all such subprocesses. The other cases are: ${run, transport
3284 filters, and the commands run by the lmtp and pipe transports.

3286 6. Added CONFIGURE_GROUP build-time option.
3287
3288 7. Some older OS have a limit of 256 on the maximum number of file
3289 descriptors. Exim was using setrlimit() to set 1000 as a large value
3290 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3291 systems. I've change it so that if it can't get 1000, it tries for 256.

3293 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3294 was an oversight, and furthermore, ever since the addition of extra
3295 controls (e.g. 4.43/32), the checks on when to allow different forms of
3296 "control" were broken. There should now be diagnostics for all cases when a
3297 control that does not make sense is encountered.

3339 ignore_target_hosts.
3340
334123. When checking ignore_target_hosts for an ipliteral router, no host name was
3342 being passed; this would have caused $sender_host_name to have been used if
3343 matching the list had actually called for a host name (not very likely,
3344 since this list is usually IP addresses). A host name is now passed as
3345 "[x.x.x.x]".

334724. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3348 code that specifies a non-restarting handler (typically sigaction() in
3349 modern systems) in an attempt to fix a rare and obscure crash bug.
3350
335125. Narrowed the window for a race in the daemon that could cause it to ignore
3352 SIGCHLD signals. This is not a major problem, because they are used only to
3353 wake it up if nothing else does.

335526. A malformed maildirsize file could cause Exim to calculate negative values
3356 for the mailbox size or file count. Odd effects could occur as a result.
3357 The maildirsize information is now recalculated if the size or filecount
3358 end up negative.

336529. In an address list, if the pattern was not a regular expression, an empty
3366 subject address (from a bounce message) matched only if the pattern was an
3367 empty string. Non-empty patterns were not even tested. This was the wrong
3368 because it is perfectly reasonable to use an empty address as part of a
3369 database query. An empty address is now tested by patterns that are
3370 lookups. However, all the other forms of pattern expect the subject to
3371 contain a local part and a domain, and therefore, for them, an empty
3372 address still always fails if the pattern is not itself empty.

337430. Exim went into a mad DNS loop when attempting to do a callout where the

337831. Re-factored the code for checking spool and log partition space into a
3379 function that finds that data and another that does the check. The former

3381 $spool_inodes, and $log_inodes.

3386 generates multiple encoded words if nece
