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".

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.

TF
384TF/03 Make the exiwhat support code safe for signals. Previously Exim might
385 lock up or crash if it happened to be inside a call to libc when it
386 got a SIGUSR1 from exiwhat.
387
388 The SIGUSR1 handler appends the current process status to the process
389 log which is later printed by exiwhat. It used to use the general
390 purpose logging code to do this, but several functions it calls are
391 not safe for signals.
392
393 The new output code in the SIGUSR1 handler is specific to the process
394 log, and simple enough that it's easy to inspect for signal safety.
395 Removing some special cases also simplifies the general logging code.
396 Removing the spurious timestamps from the process log simplifies
397 exiwhat.
398
c99ce5c9
TF
399TF/04 Improved ratelimit ACL condition.
400
401 The /noupdate option has been deprecated in favour of /readonly which
402 has clearer semantics. The /leaky, /strict, and /readonly update modes
403 are mutually exclusive. The update mode is no longer included in the
404 database key; it just determines when the database is updated. (This
405 means that when you upgrde Exim will forget old rate measurements.)
406
407 Exim now checks that the per_* options are used with an update mode that
408 makes sense for the current ACL. For example, when Exim is processing a
409 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
410 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
411 must specify per_mail/readonly. If you omit the update mode it defaults to
412 /leaky where that makes sense (as before) or /readonly where required.
413
414 The /noupdate option is now undocumented but still supported for
415 backwards compatibility. It is equivalent to /readonly except that in
416 ACLs where /readonly is required you may specify /leaky/noupdate or
417 /strict/noupdate which are treated the same as /readonly.
418
419 A useful new feature is the /count= option. This is a generalization
420 of the per_byte option, so that you can measure the throughput of other
421 aggregate values. For example, the per_byte option is now equivalent
422 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
423
424 The per_rcpt option has been generalized using the /count= mechanism
425 (though it's more complicated than the per_byte equivalence). When it is
426 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
427 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
428 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
429 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
430 Note that using per_rcpt with a non-readonly update mode in more than
431 one ACL will cause the recipients to be double-counted. (The per_mail
432 and per_byte options don't have this problem.)
433
434 The handling of very low rates has changed slightly. If the computed rate
435 is less than the event's count (usually one) then this event is the first
436 after a long gap. In this case the rate is set to the same as this event's
437 count, so that the first message of a spam run is counted properly.
438
439 The major new feature is a mechanism for counting the rate of unique
440 events. The new per_addr option counts the number of different
441 recipients that someone has sent messages to in the last time period. It
442 behaves like per_rcpt if all the recipient addresses are different, but
443 duplicate recipient addresses do not increase the measured rate. Like
444 the /count= option this is a general mechanism, so the per_addr option
445 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
446 example, measure the rate that a client uses different sender addresses
447 with the options per_mail/unique=$sender_address. There are further
448 details in the main documentation.

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

1020PH/01 Another patch from the Sieve maintainer.
1021
6a3bceb1
PH
1022PH/02 When an IPv6 address is converted to a string for single-key lookup
1023 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1024 dots are used instead of colons so that keys in lsearch files need not
1025 contain colons. This was done some time before quoting was made available
1026 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1027 (notated using the quote facility) so as to distinguish them from IPv4
1028 keys. This meant that lookups for IP addresses in host lists did not work
1029 for iplsearch lookups.
1030
1031 This has been fixed by arranging for IPv6 addresses to be expressed with
1032 colons if the lookup type is iplsearch. This is not incompatible, because
1033 previously such lookups could never work.
1034
1035 The situation is now rather anomolous, since one *can* have colons in
1036 ordinary lsearch keys. However, making the change in all cases is
1037 incompatible and would probably break a number of configurations.

1042MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1043 conversion specification without a maximum field width, thereby enabling
1044 a rogue spamd server to cause a buffer overflow. While nobody in their
1045 right mind would setup Exim to query an untrusted spamd server, an
1046 attacker that gains access to a server running spamd could potentially
1047 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1052MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1053 a directory entry by the name of the lookup key. Previously, if a
1054 symlink pointed to a non-existing file or a file in a directory that
1055 Exim lacked permissions to read, a lookup for a key matching that
1056 symlink would fail. Now it is enough that a matching directory entry
1057 exists, symlink or not. (Bugzilla 503.)

1240PH/29 SMTP synchronization checks are implemented when a command is read -
1241 there is a check that no more input is waiting when there shouldn't be

1243 some time before the response is written. In this time, more input might
1244 arrive, invalidly. So now there are extra checks after an ACL has run for
1245 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1246 pipelining has not been advertised.

1320 the response to the final '.' that terminates a message, but only in the
1321 case where the client has not sent further data following the '.'
1322 (unfortunately, this is allowed). However, in many cases there won't be
1323 any further data because there won't be any more messages to send. A call
1324 to select() can be used: if it shows that the input is "ready", there is
1325 either input waiting, or the socket has been closed. An attempt to read
1326 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1327 would have sent an OK response which the client would never have see.

1337
1338PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1339 fixed by 4.65/MH/01 (is this a record?) are fixed:
1340
1341 (i) An empty string was always treated as zero by the numeric comparison
1342 operators. This behaviour has been restored.
1343
1344 (ii) It is documented that the numeric comparison operators always treat
1345 their arguments as decimal numbers. This was broken in that numbers
1346 starting with 0 were being interpreted as octal.
1347
1348 While fixing these problems I realized that there was another issue that
1349 hadn't been noticed. Values of message_size_limit (both the global option
1350 and the transport option) were treated as octal if they started with 0.
1351 The documentation was vague. These values are now always treated as
1352 decimal, and I will make that clear in the documentation.

1368 is held in a short int, deliveries were likely to be lost. As such a
1369 large number of recipients for a single message is ridiculous
1370 (performance will be very, very poor), I have chosen to impose a limit
1371 rather than extend the field.

2b1c6e3a
PH
1396PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1397 callout verification, Exim cached a "reject" for the entire domain. This
1398 is correct for most verifications, but it is not correct for a recipient
1399 verification with use_sender or use_postmaster set, because in that case
1400 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1401 case of MAIL FROM:<> rejection from other early rejections (e.g.
1402 rejection of HELO). When verifying a recipient using a non-null MAIL
1403 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1404 Whatever the result of the callout, the value of the domain cache is
1405 left unchanged (for any other kind of callout, getting as far as trying
1406 RCPT means that the domain itself is ok).

1440PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1442 probably the interface on which it is arriving) and not to the outgoing
1443 callout (which could be using a different interface). This has been
1444 changed to use the value of the helo_data option from the smtp transport
1445 instead - this is what is used when a message is actually being sent. If
1446 there is no remote transport (possible with a router that sets up host
1447 addresses), $smtp_active_hostname is used.

7befa435 1450 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1451 (a) The code assumed that strncpy() returns a negative number on buffer
1452 overflow, which isn't the case. Replaced with Exim's string_format()
1453 function.
1454 (b) There were several signed/unsigned issues. I just did the minimum
1455 hacking in of casts. There is scope for a larger refactoring.
1456 (c) The code used strcasecmp() which is not a standard C function.
1457 Replaced with Exim's strcmpic() function.
1458 (d) The code set only $1; it now sets $auth1 as well.
1459 (e) A simple test gave the error "authentication client didn't specify
1460 service in request". It would seem that Dovecot has changed its
1461 interface. Fortunately there's a specification; I followed it and
1462 changed what the client sends and it appears to be working now.

1468 address A is aliased to B and C, where B exists and C does not. Without
1469 -v the output is "A verified" because verification stops after a
1470 successful redirection if more than one address is generated. However,
1471 with -v the child addresses are also verified. Exim was outputting "A
1472 failed to verify" and then showing the successful verification for C,
1473 with its parentage. It now outputs "B failed to verify", showing B's
1474 parentage before showing the successful verification of C.

1477 look up a TXT record in a specific list after matching in a combined

1479
322050c2
PH
1480PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1481 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1482 they consult the DNS. I had assumed they would set it the way they
1483 wanted; and indeed my experiments on Linux seem to show that in some
1484 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1485 To be on the safe side, however, I have now made the interface to
1486 host_find_byname() similar to host_find_bydns(), with an argument
1487 containing the DNS resolver options. The host_find_byname() function now
1488 sets these options at its start, just as host_find_bydns() does. The smtp
1489 transport options dns_qualify_single and dns_search_parents are passed to
1490 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1491 of host_find_byname() use the default settings of RES_DEFNAMES
1492 (qualify_single) but not RES_DNSRCH (search_parents).

1494PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1495 spool_read_header() do less string testing, by means of a preliminary
1496 switch on the second character of optional "-foo" lines. (This is
1497 overdue, caused by the large number of possibilities that now exist.
1498 Originally there were few.) While I was there, I also converted the
1499 str(n)cmp tests so they don't re-test the leading "-" and the first
1500 character, in the hope this might squeeze out yet more improvement.

PH
1502PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1503 flag allowing group syntax was set by the header_syntax check but not
1504 turned off, possible causing trouble later; (2) The flag was not being
1505 set at all for the header_verify test, causing "group"-style headers to
1506 be rejected. I have now set it in this case, and also caused header_
1507 verify to ignore an empty address taken from a group. While doing this, I
1508 came across some other cases where the code for allowing group syntax
1509 while scanning a header line wasn't quite right (mostly, not resetting
1510 the flag correctly in the right place). These bugs could have caused
1511 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1513PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1514 with the "reply" argument non-NULL. The code, however (which originally
1515 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1516 but it didn't always do it. This confused somebody who was copying the
1517 code for some other use. I have removed all the tests.

PH
1519PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1520 feature that was used to support insecure browsers during the U.S. crypto
1521 embargo. It requires special client support, and Exim is probably the
1522 only MTA that supported it -- and would never use it because real RSA is
1523 always available. This code has been removed, because it had the bad
1524 effect of slowing Exim down by computing (never used) parameters for the
1525 RSA_EXPORT functionality.

1530 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1531 if the connection is using TLS or if the remote IP is the same as the
1532 local IP, and the "valid-client-cert option" if a client certificate has
1533 been verified.

1564
1565PH/30 Exim was sometimes attempting to deliver messages that had suffered
1566 address errors (4xx response to RCPT) over the same connection as other
1567 messages routed to the same hosts. Such deliveries are always "forced",
1568 so retry times are not inspected. This resulted in far too many retries
1569 for the affected addresses. The effect occurred only when there were more
1570 hosts than the hosts_max_try setting in the smtp transport when it had
1571 the 4xx errors. Those hosts that it had tried were not added to the list
1572 of hosts for which the message was waiting, so if all were tried, there
1573 was no problem. Two fixes have been applied:
1574
1575 (i) If there are any address or message errors in an SMTP delivery, none
1576 of the hosts (tried or untried) are now added to the list of hosts
1577 for which the message is waiting, so the message should not be a
1578 candidate for sending over the same connection that was used for a
1579 successful delivery of some other message. This seems entirely
1580 reasonable: after all the message is NOT "waiting for some host".
1581 This is so "obvious" that I'm not sure why it wasn't done
1582 previously. Hope I haven't missed anything, but it can't do any
1583 harm, as the worst effect is to miss an optimization.
1584
1585 (ii) If, despite (i), such a delivery is accidentally attempted, the
1586 routing retry time is respected, so at least it doesn't keep
1587 hammering the server.

PH
1608PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1609 runs only) independently of the message's sender address. This meant
1610 that, if the 4xx error was in fact related to the sender, a different
1611 message to the same recipient with a different sender could confuse
1612 things. In particualar, this can happen when sending to a greylisting
1613 server, but other circumstances could also provoke similar problems.
1614 I have changed the default so that the retry time for these errors is now
1615 based a combination of the sender and recipient addresses. This change
1616 can be overridden by setting address_retry_include_sender=false in the
1617 smtp transport.

1889 kind of temporary error. A kludge has been added to help with this.
1890 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1891 554 error is used if errno is still zero or contains ENOENT (which occurs

1975PH/10 Fixed another bug related to PH/04 above: if an incoming message had a
1976 syntactically invalid From: or Reply-to: line, and a filter used this to
1977 generate an autoreply, and therefore failed to obtain an address for the
1978 autoreply, Exim could try to deliver to a non-existent relative file
1979 name, causing unrelated and misleading errors. What now happens is that
1980 it logs this as a hard delivery error, but does not attempt to create a
1981 bounce message.

1990PH/13 Domain literals for IPv6 were not recognized unless IPv6 support was
1991 compiled. In many other places in Exim, IPv6 addresses are always

1993 literals of the form [IPV4:n.n.n.n] are now always recognized.

1995PH/14 When a uid/gid is specified for the queryprogram router, it cannot be
1996 used if the router is not running as root, for example, when verifying at
1997 ACL time, or when using -bh. The debugging output from this situation was
1998 non-existent - all you got was a failure to exec. I have made two
1999 changes:
2000
2001 (a) Failures to set uid/gid, the current directory, or a process leader
2002 in a subprocess such as that created by queryprogram now generate
2003 suitable debugging ouput when -d is set.
2004
2005 (b) The queryprogram router detects when it is not running as root,
2006 outputs suitable debugging information if -d is set, and then runs
2007 the subprocess without attempting to change uid/gid.

2012PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2013 additional section of a DNS packet that returns MX or SRV records.
2014 Instead, it always explicitly searches for A/AAAA records. This avoids
2015 major problems that occur when a DNS server includes only records of one
2016 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2017 fixed another bug: if SRV records were looked up and the corresponding
2018 address records were *not* found in the additional section, the port
2019 values from the SRV records were lost.

2021PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2025PH/18 If quota_warn_message contains a From: header, Exim now refrains from

2027 errors_reply_to option, if set, is not used.
2028
727071f8
PH
2029PH/19 When calculating a retry time, Exim used to measure the "time since
2030 failure" by looking at the "first failed" field in the retry record. Now
2031 it does not use this if it is later than than the arrival time of the
2032 message. Instead it uses the arrival time. This makes for better
2033 behaviour in cases where some deliveries succeed, thus re-setting the
2034 "first failed" field. An example is a quota failure for a huge message
2035 when small messages continue to be delivered. Without this change, the
2036 "time since failure" will always be short, possible causing more frequent
2037 delivery attempts for the huge message than are intended.

PH
2134PH/42 The content-scanning code uses fopen() to create files in which to put
2135 message data. Previously it was not paying any attention to the mode of
2136 the files. Exim runs with umask(0) because the rest of the code creates
2137 files with open(), and sets the required mode explicitly. Thus, these
2138 files were ending up world-writeable. This was not a big issue, because,
2139 being within the spool directory, they were not world-accessible. I have
2140 created a function called modefopen, which takes an additional mode
2141 argument. It sets umask(777), creates the file, chmods it to the required
2142 mode, then resets the umask. All the relevant calls to fopen() in the
2143 content scanning code have been changed to use this function.

2151PH/45 When the plaintext authenticator is running as a client, the server's

2153 default, the authentication attempt is cancelled if an invalid string is
2154 received. Setting client_ignore_invalid_base64 true ignores these errors.
2155 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2156 they are received. Thus, the responses can be made to depend on the
2157 challenges. If an invalid string is ignored, an empty string is placed in
2158 the variable.

2178PH/52 Two bugs concerned with error handling when the smtp transport is
2179 used in LMTP mode:
2180
2181 (i) Exim was not creating retry information for temporary errors given
2182 for individual recipients after the DATA command when the smtp transport
2183 was used in LMTP mode. This meant that they could be retried too
2184 frequently, and not timed out correctly.
2185
2186 (ii) Exim was setting the flag that allows error details to be returned
2187 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2188 recipients that were returned after the DATA command.
2189
2190PH/53 This is related to PH/52, but is more general: for any failing address,
2191 when detailed error information was permitted to be returned to the
2192 sender, but the error was temporary, then after the final timeout, only
2193 "retry timeout exceeded" was returned. Now it returns the full error as
2194 well as "retry timeout exceeded".

PH
2264PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2265 function verify_get_ident() calls ip_connect() to connect a socket, but
2266 if the "connect()" function timed out, ip_connect() used to close the
2267 socket. However, verify_get_ident() also closes the socket later, and in
2268 between Exim writes to the log, which may get opened at this point. When
2269 the socket was closed in ip_connect(), the log could get the same file
2270 descriptor number as the socket. This naturally causes chaos. The fix is
2271 not to close the socket in ip_connect(); the socket should be closed by
2272 the function that creates it. There was only one place in the code where
2273 this was missing, in the iplookup router, which I don't think anybody now
2274 uses, but I've fixed it anyway.

2297
2298 (2) Treat a missing third argument of ${prvscheck as if it were an empty

2300
2301 (3) Reset the variables that are obtained from the first argument of
2302 ${prvscheck and used in the second argument before leaving the code,
2303 because their memory is reclaimed, so using them afterwards may do
2304 silly things.
2305
2306 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2307 one (it's much easier than Tom thought :-).

2331 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2332 not being looked up in the rDNS to get a host name, Exim was showing the
2333 IP address twice in Received: lines, even though the IP addresses were
2334 identical. For example:
2335
2336 Received: from [1.2.3.4] (helo=[1.2.3.4])
2337
2338 However, if the real host name was known, it was omitting the HELO data
2339 if it matched the actual IP address. This has been tidied up so that it
2340 doesn't show the same IP address twice.

2366PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2367 Electronic Mail") by including:
2368
2369 Auto-submitted: auto-generated
2370
2371 in the messages that it generates (bounce messages and others, such as
2372 warnings). In the case of bounce messages for non-SMTP mesages, there was
2373 also a typo: it was using "Auto_submitted" (underscore instead of
2374 hyphen). Since every message generated by Exim is necessarily in response
2375 to another message, thes have all been changed to:
2376
2377 Auto-Submitted: auto-replied
2378
2379 in accordance with these statements in the RFC:
2380
2381 The auto-replied keyword:
2382
2383 - SHOULD be used on messages sent in direct response to another
2384 message by an automatic process,
2385
2386 - MUST NOT be used on manually-generated messages,
2387
2388 - MAY be used on Delivery Status Notifications (DSNs) and Message
2389 Disposition Notifications (MDNs),
2390
2391 - MUST NOT be used on messages generated by automatic or periodic
2392 processes, except for messages which are automatic responses to
2393 other messages.

2416 other implementations, but there is no documentation so far and in fact,
2417 nobody wrote the draft yet. This extension is currently #undef'ed, thus
2418 not changing the active code.

PH
2429PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2430 canonical form (as documented). However, after a host name lookup from
2431 the IP address, check_host() was doing a simple string comparison with
2432 addresses acquired from the DNS when checking that the found name did
2433 have the original IP as one of its addresses. Since any found IPv6
2434 addresses are likely to be in abbreviated form, the comparison could
2435 fail. Luckily, there already exists a function for doing the comparison
2436 by converting both addresses to binary, so now that is used instead of
2437 the text comparison.
2438
96776534
PH
2439PH/20 There was another similar case to PH/19, when a complete host name was
2440 given in a host list; looking up its IP address could give an abbreviated
2441 form, whereas the current host's name might or might not be abbreviated.
2442 The same fix has been applied.

2736 Fortunately, Exim does not actually use EX_OK. The code used to try to
2737 preserve the sysexits.h value, by assumimg that macro definitions were
2738 scanned for macro replacements. I have been disabused of this notion,

2771TK/06 MBOX spool code: Add real "From " MBOX separator line
2772 so the .eml file is really in mbox format (even though
2773 most programs do not really care). Patch from Alex Miller.

2775TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
2776 The latter is generated from $received_to and is only set if the

2778 obviously out-of-the-box. Patch from Alex Miller.

2812PH/15 The code I had for printing potentially long long variables in PH/11

c6c2dc1d
PH
2815 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
2816 to be "long long int" or "long int". This is needed for the internal
2817 formatting function string_vformat().

PH
2819PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2820 the configuration file to be ":syslog", then the script "guesses" where
2821 the logs files are, rather than using the compiled in default. In our
2822 case the guess is not the same as the compiled default, so the script
2823 suddenly stopped working when I started to use syslog. The patch checks
2824 to see if log_file_path is "". If so, it attempts to read it from exim
2825 with no configuration file to get the compiled in version, before it
2826 falls back to the previous guessing code."

2843 and a new error check for 8bit text in MIME parts. Comparator and

2869PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
2870 databases so that it will be absolutely obvious if a crash occurs in the

2875 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
2876 picked up on a user's system that detects such things. There doesn't seem
2877 to be a gcc warning option for this - only an attribute that has to be
2878 put on the function's prototype. It seems that in Fedora Core 4 they have
2879 set this on a number of new functions. No doubt there will be more in due
2880 course.

PH
2882PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2883 specify a transport. However, if an address that was verified by such a
2884 router was the subject of a callout, Exim crashed because it tried to
2885 read the rcpt_include_affixes from the non-existent transport. Now it
2886 just assumes that the setting of that option is false. This bug was
2887 introduced by 4.51/PH/31.

PH
2897PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2898 aren't the modern standard, and it seems that some systems' include files
2899 don't always have them. Exim was already checking for some of the newer
2900 ones like T_AAAA, and defining it itself. I've added checks for all the
2901 record types that Exim uses.

PH
2903PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2904 not automatically generating a new one, as it is supposed to. This
2905 prevented TLS from working. If the file did exist, but contained invalid
2906 data, a new version was generated, as expected. It was only the case of a
2907 non-existent file that was broken.

2954
2955PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2956 that changes the way the GnuTLS parameters are stored in the cache file.
2957 The new format can be generated externally. For backward compatibility,
2958 if the data in the cache doesn't make sense, Exim assumes it has read an
2959 old-format file, and it generates new data and writes a new file. This
2960 means that you can't go back to an older release without removing the
2961 file.
2962
2963PH/03 A redirect router that has both "unseen" and "one_time" set does not
2964 work if there are any delivery delays because "one_time" forces the
2965 parent to be marked "delivered", so its unseen clone is never tried
2966 again. For this reason, Exim now forbids the simultaneous setting of
2967 these two options.
2968
2969PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2970 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2971 entry if you want to know the details. The fix, however, neglected to
2972 consider the case when local delivery batching is involved. The test for
2973 "previously delivered" was not happening when checking to see if an
2974 address could be batched with a previous (undelivered) one; under
2975 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2976 address.
1a46a8c5
PH
2977
2978PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2979 in its include files, and this causes problems building Exim.
2980
2981PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2982 header_syntax) but Exim was just ignoring anything given after a slash.
2983 In particular, this caused confusion with an attempt to use "verify =
2984 reverse_host_lookup/defer_ok". An error is now given when options are
2985 supplied for verify items that do not have them. (Maybe reverse_host_
2986 lookup should have a defer_ok option, but that's a different point.)
2987
2988PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
2989 defined by RFC 821) to 2048, because there were problems with some AUTH

PH
3038PH/19 When an Exim process that is running as root has to create an Exim log
3039 file, it does so in a subprocess that runs as exim:exim so as to get the
3040 ownership right at creation (otherwise, other Exim processes might see
3041 the file with the wrong ownership). There was no test for failure of this
3042 fork() call, which would lead to the process getting stuck as it waited
3043 for a non-existent subprocess. Forks do occasionally fail when resources
3044 run out. I reviewed all the other calls to fork(); they all seem to check
3045 for failure.

PH
3047PH/20 When checking for unexpected SMTP input at connect time (before writing
3048 the banner), Exim was not dealing correctly with a non-positive return

3050 the result was a log entry for a synchronization error with an empty
3051 string after "input=" when read() returned zero. If read() returned -1
3052 (an event I could not check), uninitialized data bytes were printed.

3063
c5ddb310
PH
3064PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3065 hadn't been configured. The fix is from Juergen Kreileder, who
3066 understands it better than I do:
3067
3068 "Here's what I see happening with three configured cyrus_sasl
3069 authenticators configured (plain, login, cram-md5):
3070
3071 On startup auth_cyrus_sasl_init() gets called for each of these.
3072 This means three calls to sasl_listmech() without a specified mech_list.
3073 => SASL tests which mechs of all available mechs actually work
3074 => three warnings about OTP not working
3075 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3076
3077 With the patch, sasl_listmech() also gets called three times. But now
3078 SASL's mech_list option is set to the server_mech specified in the the
3079 authenticator. Or in other words, the answer from sasl_listmech()
3080 gets limited to just the mech you're testing for (which is different
3081 for each call.)
3082 => the return list contains just 'plain' or 'login', 'cram-md5' or
3083 nothing depending on the value of ob->server_mech.
3084
3085 I've just tested the patch: Authentication still works fine,
3086 unavailable mechs specified in the exim configuration are still
3087 caught, and the auth.log warnings about OTP are gone."

PH
3151PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3152 the grounds that routing the same address twice would always produce the
3153 same answer. This might have been true once, but it is certainly no
3154 longer true now. Routing a child address may depend on the previous
3155 routing that produced that child. Some complicated redirection strategies
3156 went wrong when messages had multiple recipients, and made Exim's
3157 behaviour dependent on the order in which the addresses were given.
3158
3159 I have moved the duplicate checking until after the routing is complete.
3160 Exim scans the addresses that are assigned to local and remote
3161 transports, and removes any duplicates. This means that more work will be
3162 done, as duplicates will always all be routed, but duplicates are
3163 presumably rare, so I don't expect this is of any significance.

3165 For deliveries to pipes, files, and autoreplies, the duplicate checking
3166 still happens during the routing process, since they are not going to be
3167 routed further.

3169PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3170 It corrects a timeout issue with spamd. This is Ian's comment: "The
3171 background is that sometimes spamd either never reads data from a
3172 connection it has accepted, or it never writes response data. The exiscan
3173 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3174 blindly assumes that writes won't block so it may never time out."

3188PH/42 Exim no longer gives details of delivery errors for specific addresses in
3189 bounce and delay warning messages, except in certain special cases, which
3190 are as follows:
3191
3192 (a) An SMTP error message from a remote host;
3193 (b) A message specified in a :fail: redirection;
3194 (c) A message specified in a "fail" command in a system filter;
3195 (d) A message specified in a FAIL return from the queryprogram router;
3196 (e) A message specified by the cannot_route_message router option.
3197
3198 In these cases only, Exim does include the error details in bounce and
3199 warning messages. There are also a few cases where bland messages such
3200 as "unrouteable address" or "local delivery error" are given.

3208PH/45 In a pipe transport, although a timeout while waiting for the pipe
3209 process to complete was treated as a delivery failure, a timeout while
3210 writing the message to the pipe was logged, but erroneously treated as a
3211 successful delivery. Such timeouts include transport filter timeouts. For
3212 consistency with the overall process timeout, these timeouts are now
3213 treated as errors, giving rise to delivery failures by default. However,
3214 there is now a new Boolean option for the pipe transport called
3215 timeout_defer, which, if set TRUE, converts the failures into defers for
3216 both kinds of timeout. A transport filter timeout is now identified in
3217 the log output.

3222 from the Makefile to this script so that it can call the same version of
3223 "make".

3226A note about Exim versions 4.44 and 4.50
3227----------------------------------------
3228
3229Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3230changes of various kinds. As a consequence, a big documentation update was
3231needed. This delayed the release for rather longer than seemed good, especially
3232in the light of a couple of (minor) security issues. Therefore, the changes
3233that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3234release. So 4.44 and 4.50 are in effect two different branches that both start
3235from 4.43.
3236
3237I have left the 4.50 change log unchanged; it contains all the changes since
32384.43. The change log for 4.44 is below; many of its items are identical to
3239those for 4.50. This seems to be the most sensible way to preserve the
3240historical information.

3246 1. Minor wording change to the doc/README.SIEVE file.

3251 3. Closing a stable door: arrange to panic-die if setitimer() ever fails. The

3253 place.

3258 5. There are several places where Exim runs a non-Exim command in a
3259 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3260 was being done only for the command run by the queryprogram router. It is
3261 now done for all such subprocesses. The other cases are: ${run, transport
3262 filters, and the commands run by the lmtp and pipe transports.

3264 6. Added CONFIGURE_GROUP build-time option.
3265
3266 7. Some older OS have a limit of 256 on the maximum number of file
3267 descriptors. Exim was using setrlimit() to set 1000 as a large value
3268 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3269 systems. I've change it so that if it can't get 1000, it tries for 256.

3271 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3272 was an oversight, and furthermore, ever since the addition of extra
3273 controls (e.g. 4.43/32), the checks on when to allow different forms of
3274 "control" were broken. There should now be diagnostics for all cases when a
3275 control that does not make sense is encountered.

328111. Tidy the search cache before the fork to do a delivery from a message
3282 received from the command line. Otherwise the child will trigger a lookup

3284 cached ldap connection that the parent has called unbind on.

328612. If verify=recipient was followed by verify=sender in a RCPT ACL, the value
3287 of $address_data from the recipient verification was clobbered by the
3288 sender verification.

3291 $sender_address_data in subsequent conditions in the ACL statement.

331622. $host_address is now set to the target address during the checking of
3317 ignore_target_hosts.
3318
331923. When checking ignore_target_hosts for an ipliteral router, no host name was
3320 being passed; this would have caused $sender_host_name to have been used if
3321 matching the list had actually called for a host name (not very likely,
3322 since this list is usually IP addresses). A host name is now passed as
3323 "[x.x.x.x]".
3324

PH
332524. Changed the calls that set up the SIGCHLD handler in the daemon to use the
3326 code that specifies a non-restarting handler (typically sigaction() in
3327 modern systems) in an attempt to fix a rare and obscure crash bug.
3328
332925. Narrowed the window for a race in the daemon that could cause it to ignore
3330 SIGCHLD signals. This is not a major problem, because they are used only to
3331 wake it up if nothing else does.

PH
333326. A malformed maildirsize file could cause Exim to calculate negative values
3334 for the mailbox size or file count. Odd effects could occur as a result.
3335 The maildirsize information is now recalculated if the size or filecount
3336 end up negative.
3337

334329. In an address list, if the pattern was not a regular expression, an empty
3344 subject address (from a bounce message) matched only if the pattern was an
3345 empty string. Non-empty patterns were not even tested. This was the wrong
3346 because it is perfectly reasonable to use an empty address as part of a
3347 database query. An empty address is now tested by patterns that are
3348 lookups. However, all the other forms of pattern expect the subject to
3349 contain a local part and a domain, and therefore, for them, an empty
3350 address still always fails if the pattern is not itself empty.

PH
335230. Exim went into a mad DNS loop when attempting to do a callout where the
3353 host was specified on an smtp transport, and looking it up yielded more
3354 than one IP address.
3355

PH
335631. Re-factored the code for checking spool and log partition space into a
3357 function that finds that data and another that does the check. The former
3358 is then used to implement four new variables: $spool_space, $log_space,
3359 $spool_inodes, and $log_inodes.
3360

PH
336132. The RFC2047 encoding function was originally intended for short strings
3362 such as real names; it was not keeping to the 75-character limit for
3363 encoded words that the RFC imposes. It now respects the limit, and
3364 generates multiple encoded words if necessary. To be on the safe side, I
3365 have increased the buffer size for the ${rfc2047: expansion operator from
3366 1024 to 2048 bytes.
3367

PH
336833. It is now permitted to omit both strings after an "if" condition; if the
3369 condition is true, the result is "true". As before, when the second string
3370 is omitted, a false condition yields an empty string. This makes it less
3371 cumbersome to write custom ACL and router conditions.
3372
652e1b65
PH
337334. Failure to deliver a bounce message always caused it to be frozen, even if
3374 there was an errors_to setting on the router. The errors_to setting is now
3375 respected.
3376
6f0c9a4f
PH
337735. If an IPv6 address is given for -bh or -bhc, it is now converted to the
3378 canonical form (fully expanded) before being placed in
3379 $sender_host_address.
3380
33397d19
PH
338136. The table in the code that translates DNS record types into text (T_A to
3382 "A" for instance) was missing entries for NS and CNAME. It is just possible
3383 that this could have caused confusion if both these types were looked up
3384 for the same domain, because the text type is used as part of Exim's
3385 per-process caching. But the chance of anyone hitting this buglet seems
3386 very small.
