105TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
106
107 When a queue runner is handling a message, Exim first routes the
108 recipient addresses, during which it prunes them based on the retry
109 hints database. After that it attempts to deliver the message to
110 any remaining recipients. It then updates the hints database using
111 the retry rules.
112
113 So if a recipient address works intermittently, it can get repeatedly
114 deferred at routing time. The retry hints record remains fresh so the
115 address never reaches the final cutoff time.
116
117 This is a fairly common occurrence when a user is bumping up against
118 their storage quota. Exim had some logic in its local delivery code
119 to deal with this. However it did not apply to per-recipient defers
120 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
121
1ddeb334
TF
122 This change adds a proper retry rule check during routing so that the
123 final cutoff time is checked against the message's age. We only do
124 this check if there is an address retry record and there is not a
125 domain retry record; this implies that previous attempts to handle
126 the address had the retry_use_local_parts option turned on. We use
127 this as an approximation for the destination being like a local
128 delivery, as in LMTP.
67bd1ab3
TF
129
130 I suspect this new check makes the old local delivery cutoff check
131 redundant, but I have not verified this so I left the code in place.
132
326cdc37
TF
133TF/02 Correct gecos expansion when From: is a prefix of the username.
134
135 Test 0254 submits a message to Exim with the header
136
137 Resent-From: f
138
139 When I ran the test suite under the user fanf2, Exim expanded
140 the header to contain my full name, whereas it should have added
141 a Resent-Sender: header. It erroneously treats any prefix of the
142 username as equal to the username.
143
144 This change corrects that bug.

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

PP
184PP/18 OpenSSL made graceful with empty tls_verify_certificates setting.
185 This is now consistent with GnuTLS, and is now documented: the
186 previous undocumented portable approach to treating the option as
187 unset was to force an expansion failure. That still works, and
188 an empty string is now equivalent.

190PP/19 Renamed DNSSEC-enabling option to "dns_dnssec_ok", to make it

430TF/03 Make the exiwhat support code safe for signals. Previously Exim might
431 lock up or crash if it happened to be inside a call to libc when it
432 got a SIGUSR1 from exiwhat.
433
434 The SIGUSR1 handler appends the current process status to the process
435 log which is later printed by exiwhat. It used to use the general
436 purpose logging code to do this, but several functions it calls are
437 not safe for signals.
438
439 The new output code in the SIGUSR1 handler is specific to the process
440 log, and simple enough that it's easy to inspect for signal safety.
441 Removing some special cases also simplifies the general logging code.
442 Removing the spurious timestamps from the process log simplifies
443 exiwhat.

445TF/04 Improved ratelimit ACL condition.
446
447 The /noupdate option has been deprecated in favour of /readonly which
448 has clearer semantics. The /leaky, /strict, and /readonly update modes
449 are mutually exclusive. The update mode is no longer included in the
450 database key; it just determines when the database is updated. (This
451 means that when you upgrde Exim will forget old rate measurements.)
452
453 Exim now checks that the per_* options are used with an update mode that
454 makes sense for the current ACL. For example, when Exim is processing a
455 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
456 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
457 must specify per_mail/readonly. If you omit the update mode it defaults to
458 /leaky where that makes sense (as before) or /readonly where required.
459
460 The /noupdate option is now undocumented but still supported for
461 backwards compatibility. It is equivalent to /readonly except that in
462 ACLs where /readonly is required you may specify /leaky/noupdate or
463 /strict/noupdate which are treated the same as /readonly.
464
465 A useful new feature is the /count= option. This is a generalization
466 of the per_byte option, so that you can measure the throughput of other
467 aggregate values. For example, the per_byte option is now equivalent
468 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
469
470 The per_rcpt option has been generalized using the /count= mechanism
471 (though it's more complicated than the per_byte equivalence). When it is
472 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
473 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
474 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
475 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
476 Note that using per_rcpt with a non-readonly update mode in more than
477 one ACL will cause the recipients to be double-counted. (The per_mail
478 and per_byte options don't have this problem.)
479
480 The handling of very low rates has changed slightly. If the computed rate
481 is less than the event's count (usually one) then this event is the first
482 after a long gap. In this case the rate is set to the same as this event's
483 count, so that the first message of a spam run is counted properly.
484
485 The major new feature is a mechanism for counting the rate of unique
486 events. The new per_addr option counts the number of different
487 recipients that someone has sent messages to in the last time period. It
488 behaves like per_rcpt if all the recipient addresses are different, but
489 duplicate recipient addresses do not increase the measured rate. Like
490 the /count= option this is a general mechanism, so the per_addr option
491 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
492 example, measure the rate that a client uses different sender addresses
493 with the options per_mail/unique=$sender_address. There are further
494 details in the main documentation.

1045 were called 'true' and it seems that C99 defines that as a reserved

1066PH/01 Another patch from the Sieve maintainer.
1067
6a3bceb1
PH
1068PH/02 When an IPv6 address is converted to a string for single-key lookup
1069 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1070 dots are used instead of colons so that keys in lsearch files need not
1071 contain colons. This was done some time before quoting was made available
1072 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1073 (notated using the quote facility) so as to distinguish them from IPv4
1074 keys. This meant that lookups for IP addresses in host lists did not work
1075 for iplsearch lookups.
1076
1077 This has been fixed by arranging for IPv6 addresses to be expressed with
1078 colons if the lookup type is iplsearch. This is not incompatible, because
1079 previously such lookups could never work.
1080
1081 The situation is now rather anomolous, since one *can* have colons in
1082 ordinary lsearch keys. However, making the change in all cases is
1083 incompatible and would probably break a number of configurations.

MH
1088MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1089 conversion specification without a maximum field width, thereby enabling
1090 a rogue spamd server to cause a buffer overflow. While nobody in their
1091 right mind would setup Exim to query an untrusted spamd server, an
1092 attacker that gains access to a server running spamd could potentially
1093 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1098MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1099 a directory entry by the name of the lookup key. Previously, if a
1100 symlink pointed to a non-existing file or a file in a directory that
1101 Exim lacked permissions to read, a lookup for a key matching that
1102 symlink would fail. Now it is enough that a matching directory entry
1103 exists, symlink or not. (Bugzilla 503.)

1286PH/29 SMTP synchronization checks are implemented when a command is read -
1287 there is a check that no more input is waiting when there shouldn't be
1288 any. However, for some commands, a delay in an ACL can mean that it is
1289 some time before the response is written. In this time, more input might
1290 arrive, invalidly. So now there are extra checks after an ACL has run for
1291 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1292 pipelining has not been advertised.

PH
1366 the response to the final '.' that terminates a message, but only in the
1367 case where the client has not sent further data following the '.'
1368 (unfortunately, this is allowed). However, in many cases there won't be
1369 any further data because there won't be any more messages to send. A call
1370 to select() can be used: if it shows that the input is "ready", there is
1371 either input waiting, or the socket has been closed. An attempt to read
1372 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1373 would have sent an OK response which the client would never have see.

1384PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1385 fixed by 4.65/MH/01 (is this a record?) are fixed:
1386
1387 (i) An empty string was always treated as zero by the numeric comparison
1388 operators. This behaviour has been restored.
1389
1390 (ii) It is documented that the numeric comparison operators always treat
1391 their arguments as decimal numbers. This was broken in that numbers
1392 starting with 0 were being interpreted as octal.
1393
1394 While fixing these problems I realized that there was another issue that
1395 hadn't been noticed. Values of message_size_limit (both the global option
1396 and the transport option) were treated as octal if they started with 0.
1397 The documentation was vague. These values are now always treated as
1398 decimal, and I will make that clear in the documentation.

1414 is held in a short int, deliveries were likely to be lost. As such a
1415 large number of recipients for a single message is ridiculous
1416 (performance will be very, very poor), I have chosen to impose a limit
1417 rather than extend the field.

2b1c6e3a
PH
1442PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1443 callout verification, Exim cached a "reject" for the entire domain. This
1444 is correct for most verifications, but it is not correct for a recipient
1445 verification with use_sender or use_postmaster set, because in that case
1446 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1447 case of MAIL FROM:<> rejection from other early rejections (e.g.
1448 rejection of HELO). When verifying a recipient using a non-null MAIL
1449 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1450 Whatever the result of the callout, the value of the domain cache is
1451 left unchanged (for any other kind of callout, getting as far as trying
1452 RCPT means that the domain itself is ok).

1486PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1488 probably the interface on which it is arriving) and not to the outgoing
1489 callout (which could be using a different interface). This has been
1490 changed to use the value of the helo_data option from the smtp transport
1491 instead - this is what is used when a message is actually being sent. If
1492 there is no remote transport (possible with a router that sets up host
1493 addresses), $smtp_active_hostname is used.

7befa435 1496 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1497 (a) The code assumed that strncpy() returns a negative number on buffer
1498 overflow, which isn't the case. Replaced with Exim's string_format()
1499 function.
1500 (b) There were several signed/unsigned issues. I just did the minimum
1501 hacking in of casts. There is scope for a larger refactoring.
1502 (c) The code used strcasecmp() which is not a standard C function.
1503 Replaced with Exim's strcmpic() function.
1504 (d) The code set only $1; it now sets $auth1 as well.
1505 (e) A simple test gave the error "authentication client didn't specify
1506 service in request". It would seem that Dovecot has changed its
1507 interface. Fortunately there's a specification; I followed it and
1508 changed what the client sends and it appears to be working now.

1514 address A is aliased to B and C, where B exists and C does not. Without
1515 -v the output is "A verified" because verification stops after a
1516 successful redirection if more than one address is generated. However,
1517 with -v the child addresses are also verified. Exim was outputting "A
1518 failed to verify" and then showing the successful verification for C,
1519 with its parentage. It now outputs "B failed to verify", showing B's
1520 parentage before showing the successful verification of C.

322050c2
PH
1526PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1527 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1528 they consult the DNS. I had assumed they would set it the way they
1529 wanted; and indeed my experiments on Linux seem to show that in some
1530 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1531 To be on the safe side, however, I have now made the interface to
1532 host_find_byname() similar to host_find_bydns(), with an argument
1533 containing the DNS resolver options. The host_find_byname() function now
1534 sets these options at its start, just as host_find_bydns() does. The smtp
1535 transport options dns_qualify_single and dns_search_parents are passed to
1536 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1537 of host_find_byname() use the default settings of RES_DEFNAMES
1538 (qualify_single) but not RES_DNSRCH (search_parents).

1541 spool_read_header() do less string testing, by means of a preliminary
1542 switch on the second character of optional "-foo" lines. (This is
1543 overdue, caused by the large number of possibilities that now exist.
1544 Originally there were few.) While I was there, I also converted the
1545 str(n)cmp tests so they don't re-test the leading "-" and the first
1546 character, in the hope this might squeeze out yet more improvement.

1548PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1549 flag allowing group syntax was set by the header_syntax check but not
1550 turned off, possible causing trouble later; (2) The flag was not being
1551 set at all for the header_verify test, causing "group"-style headers to
1552 be rejected. I have now set it in this case, and also caused header_
1553 verify to ignore an empty address taken from a group. While doing this, I
1554 came across some other cases where the code for allowing group syntax
1555 while scanning a header line wasn't quite right (mostly, not resetting
1556 the flag correctly in the right place). These bugs could have caused
1557 trouble for malformed header lines. I hope it is now all correct.

1559PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called

1562 but it didn't always do it. This confused somebody who was copying the
1563 code for some other use. I have removed all the tests.

PH
1565PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1566 feature that was used to support insecure browsers during the U.S. crypto
1567 embargo. It requires special client support, and Exim is probably the
1568 only MTA that supported it -- and would never use it because real RSA is
1569 always available. This code has been removed, because it had the bad
1570 effect of slowing Exim down by computing (never used) parameters for the
1571 RSA_EXPORT functionality.

1576 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1577 if the connection is using TLS or if the remote IP is the same as the
1578 local IP, and the "valid-client-cert option" if a client certificate has

1611PH/30 Exim was sometimes attempting to deliver messages that had suffered
1612 address errors (4xx response to RCPT) over the same connection as other
1613 messages routed to the same hosts. Such deliveries are always "forced",
1614 so retry times are not inspected. This resulted in far too many retries
1615 for the affected addresses. The effect occurred only when there were more
1616 hosts than the hosts_max_try setting in the smtp transport when it had
1617 the 4xx errors. Those hosts that it had tried were not added to the list
1618 of hosts for which the message was waiting, so if all were tried, there
1619 was no problem. Two fixes have been applied:
1620
1621 (i) If there are any address or message errors in an SMTP delivery, none
1622 of the hosts (tried or untried) are now added to the list of hosts
1623 for which the message is waiting, so the message should not be a
1624 candidate for sending over the same connection that was used for a
1625 successful delivery of some other message. This seems entirely
1626 reasonable: after all the message is NOT "waiting for some host".
1627 This is so "obvious" that I'm not sure why it wasn't done
1628 previously. Hope I haven't missed anything, but it can't do any
1629 harm, as the worst effect is to miss an optimization.
1630
1631 (ii) If, despite (i), such a delivery is accidentally attempted, the
1632 routing retry time is respected, so at least it doesn't keep
1633 hammering the server.

1648PH/35 The error "getsockname() failed: connection reset by peer" was being
1649 written to the panic log as well as the main log, but it isn't really
1650 panic-worthy as it just means the connection died rather early on. I have
1651 removed the panic log writing for the ECONNRESET error when getsockname()
1652 fails.
1653
48c7f9e2
PH
1654PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1655 runs only) independently of the message's sender address. This meant
1656 that, if the 4xx error was in fact related to the sender, a different
1657 message to the same recipient with a different sender could confuse
1658 things. In particualar, this can happen when sending to a greylisting
1659 server, but other circumstances could also provoke similar problems.
1660 I have changed the default so that the retry time for these errors is now
1661 based a combination of the sender and recipient addresses. This change
1662 can be overridden by setting address_retry_include_sender=false in the
1663 smtp transport.

1935 kind of temporary error. A kludge has been added to help with this.
1936 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1937 554 error is used if errno is still zero or contains ENOENT (which occurs

1973-----------------
1974
1975PH/01 The code for finding all the local interface addresses on a FreeBSD
1976 system running IPv6 was broken. This may well have applied to all BSD
1977 systems, as well as to others that have similar system calls. The broken
1978 code found IPv4 interfaces correctly, but gave incorrect values for the
1979 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
1980 that it would not match correctly against @[] and not recognize the IPv6
1981 addresses as local.

1983PH/02 The ipliteral router was not recognizing addresses of the form user@
1984 [ipv6:....] because it didn't know about the "ipv6:" prefix.

PH
1988PH/04 Changed $reply_address to use the raw form of the headers instead of the
1989 decoded form, because it is most often used to construct To: headers
1990 lines in autoreplies, and the decoded form may well be syntactically
1991 invalid. However, $reply_address has leading white space removed, and all
1992 newlines turned into spaces so that the autoreply transport does not
1993 grumble.

1995PH/05 If group was specified without a user on a router, and no group or user
1996 was specified on a transport, the group from the router was ignored.

PH
1998PH/06 Increased the number of ACL variables to 20 of each type, and arranged
1999 for visible compile-time settings that can be used to change these
2000 numbers, for those that want even more. Backwards compatibility with old
2001 spool files has been maintained. However, going back to a previous Exim
2002 release will lost any variables that are in spool files.

2004PH/07 Two small changes when running in the test harness: increase delay when
2005 passing a TCP/IP connection to a new process, in case the original

2007 127.0.0.2 (sic), which is no longer necessary.

PH
2021PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
2022 syntactically invalid From: or Reply-to: line, and a filter used this to
2023 generate an autoreply, and therefore failed to obtain an address for the
2024 autoreply, Exim could try to deliver to a non-existent relative file
2025 name, causing unrelated and misleading errors. What now happens is that
2026 it logs this as a hard delivery error, but does not attempt to create a
2027 bounce message.

PH
2036PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
2037 compiled. In many other places in Exim, IPv6 addresses are always
2038 recognized, so I have changed this. It also means that IPv4 domain
2039 literals of the form [IPV4:n.n.n.n] are now always recognized.

PH
2041PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
2042 used if the router is not running as root, for example, when verifying at
2043 ACL time, or when using -bh. The debugging output from this situation was
2044 non-existent - all you got was a failure to exec. I have made two
2045 changes:
2046
2047 (a) Failures to set uid/gid, the current directory, or a process leader
2048 in a subprocess such as that created by queryprogram now generate
2049 suitable debugging ouput when -d is set.
2050
2051 (b) The queryprogram router detects when it is not running as root,
2052 outputs suitable debugging information if -d is set, and then runs
2053 the subprocess without attempting to change uid/gid.

1349e1e5
PH
2058PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2059 additional section of a DNS packet that returns MX or SRV records.
2060 Instead, it always explicitly searches for A/AAAA records. This avoids
2061 major problems that occur when a DNS server includes only records of one
2062 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2063 fixed another bug: if SRV records were looked up and the corresponding
2064 address records were *not* found in the additional section, the port
2065 values from the SRV records were lost.
2066
ea49d0e1
PH
2067PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not
2068 using the correct key (the original address) when searching the retry
2069 rules in order to find which one to use for generating the retry hint.
2070
064a94c9
PH
2071PH/18 If quota_warn_message contains a From: header, Exim now refrains from
2072 adding the default one. Similarly, if it contains a Reply-To: header, the
2073 errors_reply_to option, if set, is not used.
2074
727071f8
PH
2075PH/19 When calculating a retry time, Exim used to measure the "time since
2076 failure" by looking at the "first failed" field in the retry record. Now
2077 it does not use this if it is later than than the arrival time of the
2078 message. Instead it uses the arrival time. This makes for better
2079 behaviour in cases where some deliveries succeed, thus re-setting the
2080 "first failed" field. An example is a quota failure for a huge message
2081 when small messages continue to be delivered. Without this change, the
2082 "time since failure" will always be short, possible causing more frequent
2083 delivery attempts for the huge message than are intended.

2096 on a system where the size of off_t is not greater than 4, a panic error
2097 is given.

2101 message indicating a malformed IPv4 address or mask.
2102
2103PH/24 An host item such as 1.2.3.4/abc was being treated as the IP address
2104 1.2.3.4 without a mask. Now it is not recognized as an IP address, and
2105 PH/23 above applies.

PH
2180PH/42 The content-scanning code uses fopen() to create files in which to put
2181 message data. Previously it was not paying any attention to the mode of
2182 the files. Exim runs with umask(0) because the rest of the code creates
2183 files with open(), and sets the required mode explicitly. Thus, these
2184 files were ending up world-writeable. This was not a big issue, because,
2185 being within the spool directory, they were not world-accessible. I have
2186 created a function called modefopen, which takes an additional mode
2187 argument. It sets umask(777), creates the file, chmods it to the required
2188 mode, then resets the umask. All the relevant calls to fopen() in the
2189 content scanning code have been changed to use this function.

2200 received. Setting client_ignore_invalid_base64 true ignores these errors.
2201 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2202 they are received. Thus, the responses can be made to depend on the

2218 of files (along with the size), even though it did not need this
2219 information. It now does the scan only if it needs to find either the

2224PH/52 Two bugs concerned with error handling when the smtp transport is
2225 used in LMTP mode:
2226
2227 (i) Exim was not creating retry information for temporary errors given
2228 for individual recipients after the DATA command when the smtp transport
2229 was used in LMTP mode. This meant that they could be retried too
2230 frequently, and not timed out correctly.
2231
2232 (ii) Exim was setting the flag that allows error details to be returned
2233 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2234 recipients that were returned after the DATA command.
2235
2236PH/53 This is related to PH/52, but is more general: for any failing address,
2237 when detailed error information was permitted to be returned to the
2238 sender, but the error was temporary, then after the final timeout, only
2239 "retry timeout exceeded" was returned. Now it returns the full error as
2240 well as "retry timeout exceeded".

2310PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2311 function verify_get_ident() calls ip_connect() to connect a socket, but
2312 if the "connect()" function timed out, ip_connect() used to close the
2313 socket. However, verify_get_ident() also closes the socket later, and in
2314 between Exim writes to the log, which may get opened at this point. When
2315 the socket was closed in ip_connect(), the log could get the same file
2316 descriptor number as the socket. This naturally causes chaos. The fix is
2317 not to close the socket in ip_connect(); the socket should be closed by
2318 the function that creates it. There was only one place in the code where
2319 this was missing, in the iplookup router, which I don't think anybody now
2320 uses, but I've fixed it anyway.

2344 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2346
2347 (3) Reset the variables that are obtained from the first argument of
2348 ${prvscheck and used in the second argument before leaving the code,
2349 because their memory is reclaimed, so using them afterwards may do
2350 silly things.
2351
2352 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2353 one (it's much easier than Tom thought :-).

2376PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2377 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2378 not being looked up in the rDNS to get a host name, Exim was showing the
2379 IP address twice in Received: lines, even though the IP addresses were
2380 identical. For example:
2381
2382 Received: from [1.2.3.4] (helo=[1.2.3.4])
2383
2384 However, if the real host name was known, it was omitting the HELO data
2385 if it matched the actual IP address. This has been tidied up so that it
2386 doesn't show the same IP address twice.

2412PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2413 Electronic Mail") by including:
2414
2415 Auto-submitted: auto-generated
2416
2417 in the messages that it generates (bounce messages and others, such as
2418 warnings). In the case of bounce messages for non-SMTP mesages, there was
2419 also a typo: it was using "Auto_submitted" (underscore instead of
2420 hyphen). Since every message generated by Exim is necessarily in response
2421 to another message, thes have all been changed to:
2422
2423 Auto-Submitted: auto-replied
2424
2425 in accordance with these statements in the RFC:
2426
2427 The auto-replied keyword:
2428
2429 - SHOULD be used on messages sent in direct response to another
2430 message by an automatic process,
2431
2432 - MUST NOT be used on manually-generated messages,
2433
2434 - MAY be used on Delivery Status Notifications (DSNs) and Message
2435 Disposition Notifications (MDNs),

2475PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2476 canonical form (as documented). However, after a host name lookup from
2477 the IP address, check_host() was doing a simple string comparison with
2478 addresses acquired from the DNS when checking that the found name did
2479 have the original IP as one of its addresses. Since any found IPv6
2480 addresses are likely to be in abbreviated form, the comparison could
2481 fail. Luckily, there already exists a function for doing the comparison
2482 by converting both addresses to binary, so now that is used instead of
2483 the text comparison.

PH
2485PH/20 There was another similar case to PH/19, when a complete host name was

PH
2780PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
2781 with the definition in sysexits.h (which is #included earlier).
2782 Fortunately, Exim does not actually use EX_OK. The code used to try to
2783 preserve the sysexits.h value, by assumimg that macro definitions were
2784 scanned for macro replacements. I have been disabused of this notion,
2785 so now the code just undefines EX_OK before #including unistd.h.

2787PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
2788 in the smtp transport. When a block could not be written in a single
2789 write() function, the timeout was being re-applied to each part-write.
2790 This seems wrong - if the receiver was accepting one byte at a time it
2791 would take for ever. The timeout is now adjusted when this happens. It
2792 doesn't have to be particularly precise.

2867 the logs files are, rather than using the compiled in default. In our
2868 case the guess is not the same as the compiled default, so the script
2869 suddenly stopped working when I started to use syslog. The patch checks
2870 to see if log_file_path is "". If so, it attempts to read it from exim
2871 with no configuration file to get the compiled in version, before it
2872 falls back to the previous guessing code."

2931 read the rcpt_include_affixes from the non-existent transport. Now it

3000
3001PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3002 that changes the way the GnuTLS parameters are stored in the cache file.
3003 The new format can be generated externally. For backward compatibility,
3004 if the data in the cache doesn't make sense, Exim assumes it has read an
3005 old-format file, and it generates new data and writes a new file. This
3006 means that you can't go back to an older release without removing the
3007 file.
3008
3009PH/03 A redirect router that has both "unseen" and "one_time" set does not
3010 work if there are any delivery delays because "one_time" forces the
3011 parent to be marked "delivered", so its unseen clone is never tried
3012 again. For this reason, Exim now forbids the simultaneous setting of
3013 these two options.
3014
3015PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3016 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3017 entry if you want to know the details. The fix, however, neglected to
3018 consider the case when local delivery batching is involved. The test for
3019 "previously delivered" was not happening when checking to see if an
3020 address could be batched with a previous (undelivered) one; under
3021 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3022 address.

PH
3023
3024PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T

3026
3027PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
3028 header_syntax) but Exim was just ignoring anything given after a slash.
3029 In particular, this caused confusion with an attempt to use "verify =
3030 reverse_host_lookup/defer_ok". An error is now given when options are
3031 supplied for verify items that do not have them. (Maybe reverse_host_
3032 lookup should have a defer_ok option, but that's a different point.)
3033
3034PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as

3085 file, it does so in a subprocess that runs as exim:exim so as to get the
3086 ownership right at creation (otherwise, other Exim processes might see
3087 the file with the wrong ownership). There was no test for failure of this
3088 fork() call, which would lead to the process getting stuck as it waited
3089 for a non-existent subprocess. Forks do occasionally fail when resources
3090 run out. I reviewed all the other calls to fork(); they all seem to check

3096 the result was a log entry for a synchronization error with an empty
3097 string after "input=" when read() returned zero. If read() returned -1

PH
3110PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3111 hadn't been configured. The fix is from Juergen Kreileder, who
3112 understands it better than I do:
3113
3114 "Here's what I see happening with three configured cyrus_sasl
3115 authenticators configured (plain, login, cram-md5):
3116
3117 On startup auth_cyrus_sasl_init() gets called for each of these.
3118 This means three calls to sasl_listmech() without a specified mech_list.
3119 => SASL tests which mechs of all available mechs actually work
3120 => three warnings about OTP not working
3121 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3122
3123 With the patch, sasl_listmech() also gets called three times. But now
3124 SASL's mech_list option is set to the server_mech specified in the the
3125 authenticator. Or in other words, the answer from sasl_listmech()
3126 gets limited to just the mech you're testing for (which is different
3127 for each call.)
3128 => the return list contains just 'plain' or 'login', 'cram-md5' or
3129 nothing depending on the value of ob->server_mech.
3130
3131 I've just tested the patch: Authentication still works fine,
3132 unavailable mechs specified in the exim configuration are still

3167 . First host accepts first address;
3168 . First host gives temporary error to second address;
3169 . Second host offers TLS and a TLS session is established;
3170 . Second host accepts second address.
3171 Exim incorrectly logged both deliveries with the TLS parameters (cipher
3172 and peerdn, if requested) that were in fact used only for the second
3173 address.

3175PH/31 When doing a callout as part of verifying an address, Exim was not paying
3176 attention to any local part prefix or suffix that was matched by the
3177 router that accepted the address. It now behaves in the same way as it
3178 does for delivery: the affixes are removed from the local part unless
3179 rcpt_include_affixes is set on the transport.

3197PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3198 the grounds that routing the same address twice would always produce the
3199 same answer. This might have been true once, but it is certainly no
3200 longer true now. Routing a child address may depend on the previous
3201 routing that produced that child. Some complicated redirection strategies
3202 went wrong when messages had multiple recipients, and made Exim's
3203 behaviour dependent on the order in which the addresses were given.
3204
3205 I have moved the duplicate checking until after the routing is complete.
3206 Exim scans the addresses that are assigned to local and remote
3207 transports, and removes any duplicates. This means that more work will be
3208 done, as duplicates will always all be routed, but duplicates are
3209 presumably rare, so I don't expect this is of any significance.
3210
3211 For deliveries to pipes, files, and autoreplies, the duplicate checking
3212 still happens during the routing process, since they are not going to be
3213 routed further.

3215PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3216 It corrects a timeout issue with spamd. This is Ian's comment: "The
3217 background is that sometimes spamd either never reads data from a
3218 connection it has accepted, or it never writes response data. The exiscan
3219 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3220 blindly assumes that writes won't block so it may never time out."

3242 (e) A message specified by the cannot_route_message router option.
3243
3244 In these cases only, Exim does include the error details in bounce and
3245 warning messages. There are also a few cases where bland messages such
3246 as "unrouteable address" or "local delivery error" are given.

3254PH/45 In a pipe transport, although a timeout while waiting for the pipe
3255 process to complete was treated as a delivery failure, a timeout while
3256 writing the message to the pipe was logged, but erroneously treated as a
3257 successful delivery. Such timeouts include transport filter timeouts. For
3258 consistency with the overall process timeout, these timeouts are now
3259 treated as errors, giving rise to delivery failures by default. However,
3260 there is now a new Boolean option for the pipe transport called
3261 timeout_defer, which, if set TRUE, converts the failures into defers for
3262 both kinds of timeout. A transport filter timeout is now identified in
3263 the log output.

3272A note about Exim versions 4.44 and 4.50
3273----------------------------------------
3274
3275Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3276changes of various kinds. As a consequence, a big documentation update was
3277needed. This delayed the release for rather longer than seemed good, especially
3278in the light of a couple of (minor) security issues. Therefore, the changes
3279that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3280release. So 4.44 and 4.50 are in effect two different branches that both start
3281from 4.43.
3282
3283I have left the 4.50 change log unchanged; it contains all the changes since
32844.43. The change log for 4.44 is below; many of its items are identical to
3285those for 4.50. This seems to be the most sensible way to preserve the
3286historical information.

3304 5. There are several places where Exim runs a non-Exim command in a
3305 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3306 was being done only for the command run by the queryprogram router. It is
3307 now done for all such subprocesses. The other cases are: ${run, transport
3308 filters, and the commands run by the lmtp and pipe transports.

3312 7. Some older OS have a limit of 256 on the maximum number of file
3313 descriptors. Exim was using setrlimit() to set 1000 as a large value
3314 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3315 systems. I've change it so that if it can't get 1000, it tries for 256.

3317 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3318 was an oversight, and furthermore, ever since the addition of extra
3319 controls (e.g. 4.43/32), the checks on when to allow different forms of
3320 "control" were broken. There should now be diagnostics for all cases when a
3321 control that does not make sense is encountered.

3364
336523. When checking ignore_target_hosts for an ipliteral router, no host name was
3366 being passed; this would have caused $sender_host_name to have been used if
3367 matching the list had actually called for a host name (not very likely,
3368 since this list is usually IP addresses). A host name is now passed as
3369 "[x.x.x.x]".

337124. Changed the calls that set up the SIGCHLD handler in the daemon to use the

3373 modern systems) in an attempt to fix a rare and obscure crash bug.
3374
337525. Narrowed the window for a race in the daemon that could cause it to ignore
3376 SIGCHLD signals. This is not a major problem, because they are used only to
3377 wake it up if nothing else does.
