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.

145GF/01 DCC debug and logging tidyup
146 Error conditions log to paniclog rather than rejectlog.

PP
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.

TF
400TF/03 Make the exiwhat support code safe for signals. Previously Exim might
401 lock up or crash if it happened to be inside a call to libc when it
402 got a SIGUSR1 from exiwhat.
403
404 The SIGUSR1 handler appends the current process status to the process
405 log which is later printed by exiwhat. It used to use the general
406 purpose logging code to do this, but several functions it calls are
407 not safe for signals.
408
409 The new output code in the SIGUSR1 handler is specific to the process
410 log, and simple enough that it's easy to inspect for signal safety.

415TF/04 Improved ratelimit ACL condition.
416
417 The /noupdate option has been deprecated in favour of /readonly which
418 has clearer semantics. The /leaky, /strict, and /readonly update modes
419 are mutually exclusive. The update mode is no longer included in the
420 database key; it just determines when the database is updated. (This
421 means that when you upgrde Exim will forget old rate measurements.)
422
423 Exim now checks that the per_* options are used with an update mode that
424 makes sense for the current ACL. For example, when Exim is processing a
425 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
426 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
427 must specify per_mail/readonly. If you omit the update mode it defaults to
428 /leaky where that makes sense (as before) or /readonly where required.
429
430 The /noupdate option is now undocumented but still supported for
431 backwards compatibility. It is equivalent to /readonly except that in
432 ACLs where /readonly is required you may specify /leaky/noupdate or
433 /strict/noupdate which are treated the same as /readonly.
434
435 A useful new feature is the /count= option. This is a generalization
436 of the per_byte option, so that you can measure the throughput of other
437 aggregate values. For example, the per_byte option is now equivalent
438 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
439
440 The per_rcpt option has been generalized using the /count= mechanism
441 (though it's more complicated than the per_byte equivalence). When it is
442 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
443 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
444 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
445 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
446 Note that using per_rcpt with a non-readonly update mode in more than
447 one ACL will cause the recipients to be double-counted. (The per_mail
448 and per_byte options don't have this problem.)
449
450 The handling of very low rates has changed slightly. If the computed rate
451 is less than the event's count (usually one) then this event is the first
452 after a long gap. In this case the rate is set to the same as this event's
453 count, so that the first message of a spam run is counted properly.
454
455 The major new feature is a mechanism for counting the rate of unique
456 events. The new per_addr option counts the number of different
457 recipients that someone has sent messages to in the last time period. It
458 behaves like per_rcpt if all the recipient addresses are different, but
459 duplicate recipient addresses do not increase the measured rate. Like
460 the /count= option this is a general mechanism, so the per_addr option
461 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
462 example, measure the rate that a client uses different sender addresses
463 with the options per_mail/unique=$sender_address. There are further
464 details in the main documentation.

1015 were called 'true' and it seems that C99 defines that as a reserved

1017 not include C99-style headers which use bools without triggering

1037
6a3bceb1
PH
1038PH/02 When an IPv6 address is converted to a string for single-key lookup
1039 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1040 dots are used instead of colons so that keys in lsearch files need not
1041 contain colons. This was done some time before quoting was made available
1042 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1043 (notated using the quote facility) so as to distinguish them from IPv4
1044 keys. This meant that lookups for IP addresses in host lists did not work
1045 for iplsearch lookups.
1046
1047 This has been fixed by arranging for IPv6 addresses to be expressed with
1048 colons if the lookup type is iplsearch. This is not incompatible, because
1049 previously such lookups could never work.
1050
1051 The situation is now rather anomolous, since one *can* have colons in
1052 ordinary lsearch keys. However, making the change in all cases is
1053 incompatible and would probably break a number of configurations.

1058MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1059 conversion specification without a maximum field width, thereby enabling
1060 a rogue spamd server to cause a buffer overflow. While nobody in their
1061 right mind would setup Exim to query an untrusted spamd server, an
1062 attacker that gains access to a server running spamd could potentially
1063 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1068MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1069 a directory entry by the name of the lookup key. Previously, if a
1070 symlink pointed to a non-existing file or a file in a directory that
1071 Exim lacked permissions to read, a lookup for a key matching that
1072 symlink would fail. Now it is enough that a matching directory entry
1073 exists, symlink or not. (Bugzilla 503.)

PH
1256PH/29 SMTP synchronization checks are implemented when a command is read -
1257 there is a check that no more input is waiting when there shouldn't be
1258 any. However, for some commands, a delay in an ACL can mean that it is
1259 some time before the response is written. In this time, more input might
1260 arrive, invalidly. So now there are extra checks after an ACL has run for
1261 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1262 pipelining has not been advertised.

1277 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1278 was a macro that became an assignment, so it seemed to work. This has

1311 started the daemon, but after a SIGHUP it used the Exim user (because it

1318 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1336 the response to the final '.' that terminates a message, but only in the
1337 case where the client has not sent further data following the '.'
1338 (unfortunately, this is allowed). However, in many cases there won't be
1339 any further data because there won't be any more messages to send. A call
1340 to select() can be used: if it shows that the input is "ready", there is
1341 either input waiting, or the socket has been closed. An attempt to read
1342 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1343 would have sent an OK response which the client would never have see.

1351Exim version 4.66
1352-----------------
1353
1354PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1355 fixed by 4.65/MH/01 (is this a record?) are fixed:
1356
1357 (i) An empty string was always treated as zero by the numeric comparison
1358 operators. This behaviour has been restored.
1359
1360 (ii) It is documented that the numeric comparison operators always treat
1361 their arguments as decimal numbers. This was broken in that numbers
1362 starting with 0 were being interpreted as octal.
1363
1364 While fixing these problems I realized that there was another issue that
1365 hadn't been noticed. Values of message_size_limit (both the global option
1366 and the transport option) were treated as octal if they started with 0.
1367 The documentation was vague. These values are now always treated as
1368 decimal, and I will make that clear in the documentation.

PH
1382PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1383 child addresses, Exim now panics and dies. Previously, because the count
1384 is held in a short int, deliveries were likely to be lost. As such a
1385 large number of recipients for a single message is ridiculous
1386 (performance will be very, very poor), I have chosen to impose a limit
1387 rather than extend the field.

1393TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1394 leftover -K file (the existence of which was triggered by #402).

1403TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1412PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1413 callout verification, Exim cached a "reject" for the entire domain. This
1414 is correct for most verifications, but it is not correct for a recipient
1415 verification with use_sender or use_postmaster set, because in that case
1416 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1417 case of MAIL FROM:<> rejection from other early rejections (e.g.
1418 rejection of HELO). When verifying a recipient using a non-null MAIL
1419 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1420 Whatever the result of the callout, the value of the domain cache is
1421 left unchanged (for any other kind of callout, getting as far as trying
1422 RCPT means that the domain itself is ok).

1456PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1457 hostname. This is wrong, because it relates to the incoming message (and
1458 probably the interface on which it is arriving) and not to the outgoing
1459 callout (which could be using a different interface). This has been
1460 changed to use the value of the helo_data option from the smtp transport
1461 instead - this is what is used when a message is actually being sent. If
1462 there is no remote transport (possible with a router that sets up host
1463 addresses), $smtp_active_hostname is used.

14aa5a05 1465PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1466 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1467 (a) The code assumed that strncpy() returns a negative number on buffer
1468 overflow, which isn't the case. Replaced with Exim's string_format()
1469 function.
1470 (b) There were several signed/unsigned issues. I just did the minimum
1471 hacking in of casts. There is scope for a larger refactoring.
1472 (c) The code used strcasecmp() which is not a standard C function.
1473 Replaced with Exim's strcmpic() function.
1474 (d) The code set only $1; it now sets $auth1 as well.
1475 (e) A simple test gave the error "authentication client didn't specify
1476 service in request". It would seem that Dovecot has changed its
1477 interface. Fortunately there's a specification; I followed it and
1478 changed what the client sends and it appears to be working now.

1483PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1484 address A is aliased to B and C, where B exists and C does not. Without
1485 -v the output is "A verified" because verification stops after a
1486 successful redirection if more than one address is generated. However,
1487 with -v the child addresses are also verified. Exim was outputting "A
1488 failed to verify" and then showing the successful verification for C,
1489 with its parentage. It now outputs "B failed to verify", showing B's
1490 parentage before showing the successful verification of C.

1493 look up a TXT record in a specific list after matching in a combined

1495
322050c2
PH
1496PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1497 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1498 they consult the DNS. I had assumed they would set it the way they
1499 wanted; and indeed my experiments on Linux seem to show that in some
1500 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1501 To be on the safe side, however, I have now made the interface to
1502 host_find_byname() similar to host_find_bydns(), with an argument
1503 containing the DNS resolver options. The host_find_byname() function now
1504 sets these options at its start, just as host_find_bydns() does. The smtp
1505 transport options dns_qualify_single and dns_search_parents are passed to
1506 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1507 of host_find_byname() use the default settings of RES_DEFNAMES
1508 (qualify_single) but not RES_DNSRCH (search_parents).

1510PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1511 spool_read_header() do less string testing, by means of a preliminary
1512 switch on the second character of optional "-foo" lines. (This is
1513 overdue, caused by the large number of possibilities that now exist.
1514 Originally there were few.) While I was there, I also converted the
1515 str(n)cmp tests so they don't re-test the leading "-" and the first
1516 character, in the hope this might squeeze out yet more improvement.

PH
1518PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1519 flag allowing group syntax was set by the header_syntax check but not
1520 turned off, possible causing trouble later; (2) The flag was not being
1521 set at all for the header_verify test, causing "group"-style headers to
1522 be rejected. I have now set it in this case, and also caused header_
1523 verify to ignore an empty address taken from a group. While doing this, I
1524 came across some other cases where the code for allowing group syntax
1525 while scanning a header line wasn't quite right (mostly, not resetting
1526 the flag correctly in the right place). These bugs could have caused
1527 trouble for malformed header lines. I hope it is now all correct.

PH
1529PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1530 with the "reply" argument non-NULL. The code, however (which originally
1531 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1532 but it didn't always do it. This confused somebody who was copying the
1533 code for some other use. I have removed all the tests.

PH
1535PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1536 feature that was used to support insecure browsers during the U.S. crypto
1537 embargo. It requires special client support, and Exim is probably the
1538 only MTA that supported it -- and would never use it because real RSA is
1539 always available. This code has been removed, because it had the bad
1540 effect of slowing Exim down by computing (never used) parameters for the
1541 RSA_EXPORT functionality.

1546 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1547 if the connection is using TLS or if the remote IP is the same as the
1548 local IP, and the "valid-client-cert option" if a client certificate has
1549 been verified.

1581PH/30 Exim was sometimes attempting to deliver messages that had suffered
1582 address errors (4xx response to RCPT) over the same connection as other
1583 messages routed to the same hosts. Such deliveries are always "forced",
1584 so retry times are not inspected. This resulted in far too many retries
1585 for the affected addresses. The effect occurred only when there were more
1586 hosts than the hosts_max_try setting in the smtp transport when it had
1587 the 4xx errors. Those hosts that it had tried were not added to the list
1588 of hosts for which the message was waiting, so if all were tried, there
1589 was no problem. Two fixes have been applied:
1590
1591 (i) If there are any address or message errors in an SMTP delivery, none
1592 of the hosts (tried or untried) are now added to the list of hosts
1593 for which the message is waiting, so the message should not be a
1594 candidate for sending over the same connection that was used for a
1595 successful delivery of some other message. This seems entirely
1596 reasonable: after all the message is NOT "waiting for some host".
1597 This is so "obvious" that I'm not sure why it wasn't done
1598 previously. Hope I haven't missed anything, but it can't do any
1599 harm, as the worst effect is to miss an optimization.
1600
1601 (ii) If, despite (i), such a delivery is accidentally attempted, the
1602 routing retry time is respected, so at least it doesn't keep
1603 hammering the server.

1618PH/35 The error "getsockname() failed: connection reset by peer" was being
1619 written to the panic log as well as the main log, but it isn't really
1620 panic-worthy as it just means the connection died rather early on. I have
1621 removed the panic log writing for the ECONNRESET error when getsockname()
1622 fails.
1623
48c7f9e2
PH
1624PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1625 runs only) independently of the message's sender address. This meant
1626 that, if the 4xx error was in fact related to the sender, a different
1627 message to the same recipient with a different sender could confuse
1628 things. In particualar, this can happen when sending to a greylisting
1629 server, but other circumstances could also provoke similar problems.
1630 I have changed the default so that the retry time for these errors is now
1631 based a combination of the sender and recipient addresses. This change
1632 can be overridden by setting address_retry_include_sender=false in the
1633 smtp transport.

1635PH/37 For LMTP over TCP/IP (the smtp transport), error responses from the

1638 same for both kinds of LMTP.

1904 tcp-wrappers gives "deny", whereas what one would like would be some
1905 kind of temporary error. A kludge has been added to help with this.
1906 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
1907 554 error is used if errno is still zero or contains ENOENT (which occurs
1908 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

1994 autoreply, Exim could try to deliver to a non-existent relative file

2028PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2029 additional section of a DNS packet that returns MX or SRV records.
2030 Instead, it always explicitly searches for A/AAAA records. This avoids
2031 major problems that occur when a DNS server includes only records of one
2032 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2033 fixed another bug: if SRV records were looked up and the corresponding
2034 address records were *not* found in the additional section, the port
2035 values from the SRV records were lost.

2045PH/19 When calculating a retry time, Exim used to measure the "time since
2046 failure" by looking at the "first failed" field in the retry record. Now
2047 it does not use this if it is later than than the arrival time of the
2048 message. Instead it uses the arrival time. This makes for better
2049 behaviour in cases where some deliveries succeed, thus re-setting the
2050 "first failed" field. An example is a quota failure for a huge message
2051 when small messages continue to be delivered. Without this change, the
2052 "time since failure" will always be short, possible causing more frequent
2053 delivery attempts for the huge message than are intended.

PH
2150PH/42 The content-scanning code uses fopen() to create files in which to put
2151 message data. Previously it was not paying any attention to the mode of
2152 the files. Exim runs with umask(0) because the rest of the code creates
2153 files with open(), and sets the required mode explicitly. Thus, these
2154 files were ending up world-writeable. This was not a big issue, because,
2155 being within the spool directory, they were not world-accessible. I have
2156 created a function called modefopen, which takes an additional mode
2157 argument. It sets umask(777), creates the file, chmods it to the required
2158 mode, then resets the umask. All the relevant calls to fopen() in the
2159 content scanning code have been changed to use this function.

2171 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2196
2197 (i) Exim was not creating retry information for temporary errors given
2198 for individual recipients after the DATA command when the smtp transport
2199 was used in LMTP mode. This meant that they could be retried too
2200 frequently, and not timed out correctly.
2201
2202 (ii) Exim was setting the flag that allows error details to be returned
2203 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2204 recipients that were returned after the DATA command.
2205
2206PH/53 This is related to PH/52, but is more general: for any failing address,
2207 when detailed error information was permitted to be returned to the
2208 sender, but the error was temporary, then after the final timeout, only
2209 "retry timeout exceeded" was returned. Now it returns the full error as

2280PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2281 function verify_get_ident() calls ip_connect() to connect a socket, but
2282 if the "connect()" function timed out, ip_connect() used to close the
2283 socket. However, verify_get_ident() also closes the socket later, and in
2284 between Exim writes to the log, which may get opened at this point. When
2285 the socket was closed in ip_connect(), the log could get the same file
2286 descriptor number as the socket. This naturally causes chaos. The fix is
2287 not to close the socket in ip_connect(); the socket should be closed by
2288 the function that creates it. There was only one place in the code where
2289 this was missing, in the iplookup router, which I don't think anybody now
2290 uses, but I've fixed it anyway.

2318 ${prvscheck and used in the second argument before leaving the code,
2319 because their memory is reclaimed, so using them afterwards may do
2320 silly things.

2350 identical. For example:
2351
2352 Received: from [1.2.3.4] (helo=[1.2.3.4])
2353
2354 However, if the real host name was known, it was omitting the HELO data

2382PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2383 Electronic Mail") by including:
2384
2385 Auto-submitted: auto-generated
2386
2387 in the messages that it generates (bounce messages and others, such as
2388 warnings). In the case of bounce messages for non-SMTP mesages, there was
2389 also a typo: it was using "Auto_submitted" (underscore instead of
2390 hyphen). Since every message generated by Exim is necessarily in response
2391 to another message, thes have all been changed to:
2392
2393 Auto-Submitted: auto-replied
2394
2395 in accordance with these statements in the RFC:
2396
2397 The auto-replied keyword:
2398
2399 - SHOULD be used on messages sent in direct response to another
2400 message by an automatic process,
2401
2402 - MUST NOT be used on manually-generated messages,
2403
2404 - MAY be used on Delivery Status Notifications (DSNs) and Message
2405 Disposition Notifications (MDNs),
2406
2407 - MUST NOT be used on messages generated by automatic or periodic
2408 processes, except for messages which are automatic responses to
2409 other messages.

2445PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2446 canonical form (as documented). However, after a host name lookup from
2447 the IP address, check_host() was doing a simple string comparison with
2448 addresses acquired from the DNS when checking that the found name did
2449 have the original IP as one of its addresses. Since any found IPv6
2450 addresses are likely to be in abbreviated form, the comparison could
2451 fail. Luckily, there already exists a function for doing the comparison
2452 by converting both addresses to binary, so now that is used instead of
2453 the text comparison.

96776534
PH
2455PH/20 There was another similar case to PH/19, when a complete host name was

2753 preserve the sysexits.h value, by assumimg that macro definitions were

2828PH/15 The code I had for printing potentially long long variables in PH/11

PH
2831 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
2832 to be "long long int" or "long int". This is needed for the internal
2833 formatting function string_vformat().

2835PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
2836 the configuration file to be ":syslog", then the script "guesses" where
2837 the logs files are, rather than using the compiled in default. In our
2838 case the guess is not the same as the compiled default, so the script
2839 suddenly stopped working when I started to use syslog. The patch checks
2840 to see if log_file_path is "". If so, it attempts to read it from exim
2841 with no configuration file to get the compiled in version, before it
2842 falls back to the previous guessing code."

2859 and a new error check for 8bit text in MIME parts. Comparator and

2892 picked up on a user's system that detects such things. There doesn't seem
2893 to be a gcc warning option for this - only an attribute that has to be
2894 put on the function's prototype. It seems that in Fedora Core 4 they have
2895 set this on a number of new functions. No doubt there will be more in due
2896 course.

PH
2898PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
2899 specify a transport. However, if an address that was verified by such a
2900 router was the subject of a callout, Exim crashed because it tried to
2901 read the rcpt_include_affixes from the non-existent transport. Now it
2902 just assumes that the setting of that option is false. This bug was
2903 introduced by 4.51/PH/31.

PH
2913PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
2914 aren't the modern standard, and it seems that some systems' include files
2915 don't always have them. Exim was already checking for some of the newer
2916 ones like T_AAAA, and defining it itself. I've added checks for all the
2917 record types that Exim uses.

PH
2919PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
2920 not automatically generating a new one, as it is supposed to. This
2921 prevented TLS from working. If the file did exist, but contained invalid
2922 data, a new version was generated, as expected. It was only the case of a
2923 non-existent file that was broken.

2939 same time.

2970
2971PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
2972 that changes the way the GnuTLS parameters are stored in the cache file.
2973 The new format can be generated externally. For backward compatibility,
2974 if the data in the cache doesn't make sense, Exim assumes it has read an
2975 old-format file, and it generates new data and writes a new file. This
2976 means that you can't go back to an older release without removing the
2977 file.
2978
2979PH/03 A redirect router that has both "unseen" and "one_time" set does not
2980 work if there are any delivery delays because "one_time" forces the
2981 parent to be marked "delivered", so its unseen clone is never tried
2982 again. For this reason, Exim now forbids the simultaneous setting of
2983 these two options.
2984
2985PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
2986 redirected to themselves ("homonym" addresses). Read the long ChangeLog
2987 entry if you want to know the details. The fix, however, neglected to
2988 consider the case when local delivery batching is involved. The test for
2989 "previously delivered" was not happening when checking to see if an
2990 address could be batched with a previous (undelivered) one; under
2991 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 2992 address.
1a46a8c5
PH
2993
2994PH/05 Renamed the macro SOCKLEN_T as EXIM_SOCKLEN_T because AIX uses SOCKLEN_T
2995 in its include files, and this causes problems building Exim.
2996
2997PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =
2998 header_syntax) but Exim was just ignoring anything given after a slash.
2999 In particular, this caused confusion with an attempt to use "verify =
3000 reverse_host_lookup/defer_ok". An error is now given when options are
3001 supplied for verify items that do not have them. (Maybe reverse_host_
3002 lookup should have a defer_ok option, but that's a different point.)
3003
3004PH/07 Increase the size of the buffer for incoming SMTP commands from 512 (as
3005 defined by RFC 821) to 2048, because there were problems with some AUTH
3006 commands, and RFC 1869 says the size should be increased for extended
3007 SMTP commands that take arguments.

PH
3054PH/19 When an Exim process that is running as root has to create an Exim log
3055 file, it does so in a subprocess that runs as exim:exim so as to get the
3056 ownership right at creation (otherwise, other Exim processes might see
3057 the file with the wrong ownership). There was no test for failure of this
3058 fork() call, which would lead to the process getting stuck as it waited
3059 for a non-existent subprocess. Forks do occasionally fail when resources
3060 run out. I reviewed all the other calls to fork(); they all seem to check
3061 for failure.

PH
3063PH/20 When checking for unexpected SMTP input at connect time (before writing
3064 the banner), Exim was not dealing correctly with a non-positive return
3065 from the read() function. If the client had disconnected by this time,
3066 the result was a log entry for a synchronization error with an empty
3067 string after "input=" when read() returned zero. If read() returned -1
3068 (an event I could not check), uninitialized data bytes were printed.

c5ddb310
PH
3080PH/24 The cyrus_sasl authenticator was advertising mechanisms for which it
3081 hadn't been configured. The fix is from Juergen Kreileder, who
3082 understands it better than I do:
3083
3084 "Here's what I see happening with three configured cyrus_sasl
3085 authenticators configured (plain, login, cram-md5):
3086
3087 On startup auth_cyrus_sasl_init() gets called for each of these.
3088 This means three calls to sasl_listmech() without a specified mech_list.
3089 => SASL tests which mechs of all available mechs actually work
3090 => three warnings about OTP not working
3091 => the returned list contains: plain, login, cram-md5, digest-md5, ...
3092
3093 With the patch, sasl_listmech() also gets called three times. But now
3094 SASL's mech_list option is set to the server_mech specified in the the
3095 authenticator. Or in other words, the answer from sasl_listmech()
3096 gets limited to just the mech you're testing for (which is different
3097 for each call.)
3098 => the return list contains just 'plain' or 'login', 'cram-md5' or
3099 nothing depending on the value of ob->server_mech.
3100
3101 I've just tested the patch: Authentication still works fine,
3102 unavailable mechs specified in the exim configuration are still
3103 caught, and the auth.log warnings about OTP are gone."

3167PH/37 Exim used to check for duplicate addresses in the middle of routing, on
3168 the grounds that routing the same address twice would always produce the
3169 same answer. This might have been true once, but it is certainly no
3170 longer true now. Routing a child address may depend on the previous
3171 routing that produced that child. Some complicated redirection strategies
3172 went wrong when messages had multiple recipients, and made Exim's
3173 behaviour dependent on the order in which the addresses were given.
3174
3175 I have moved the duplicate checking until after the routing is complete.
3176 Exim scans the addresses that are assigned to local and remote
3177 transports, and removes any duplicates. This means that more work will be
3178 done, as duplicates will always all be routed, but duplicates are
3179 presumably rare, so I don't expect this is of any significance.
3180
3181 For deliveries to pipes, files, and autoreplies, the duplicate checking
3182 still happens during the routing process, since they are not going to be
3183 routed further.

3185PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
3186 It corrects a timeout issue with spamd. This is Ian's comment: "The
3187 background is that sometimes spamd either never reads data from a
3188 connection it has accepted, or it never writes response data. The exiscan
3189 spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
3190 blindly assumes that writes won't block so it may never time out."

3204PH/42 Exim no longer gives details of delivery errors for specific addresses in
3205 bounce and delay warning messages, except in certain special cases, which
3206 are as follows:

3208 (a) An SMTP error message from a remote host;
3209 (b) A message specified in a :fail: redirection;
3210 (c) A message specified in a "fail" command in a system filter;
3211 (d) A message specified in a FAIL return from the queryprogram router;
3212 (e) A message specified by the cannot_route_message router option.
3213
3214 In these cases only, Exim does include the error details in bounce and
3215 warning messages. There are also a few cases where bland messages such
3216 as "unrouteable address" or "local delivery error" are given.

3224PH/45 In a pipe transport, although a timeout while waiting for the pipe
3225 process to complete was treated as a delivery failure, a timeout while
3226 writing the message to the pipe was logged, but erroneously treated as a
3227 successful delivery. Such timeouts include transport filter timeouts. For
3228 consistency with the overall process timeout, these timeouts are now
3229 treated as errors, giving rise to delivery failures by default. However,
3230 there is now a new Boolean option for the pipe transport called
3231 timeout_defer, which, if set TRUE, converts the failures into defers for
3232 both kinds of timeout. A transport filter timeout is now identified in
3233 the log output.

3242A note about Exim versions 4.44 and 4.50
3243----------------------------------------
3244
3245Exim 4.50 was meant to be the next release after 4.43. It contains a lot of
3246changes of various kinds. As a consequence, a big documentation update was
3247needed. This delayed the release for rather longer than seemed good, especially
3248in the light of a couple of (minor) security issues. Therefore, the changes
3249that fixed bugs were backported into 4.43, to create a 4.44 maintenance
3250release. So 4.44 and 4.50 are in effect two different branches that both start
3251from 4.43.
3252
3253I have left the 4.50 change log unchanged; it contains all the changes since
32544.43. The change log for 4.44 is below; many of its items are identical to
3255those for 4.50. This seems to be the most sensible way to preserve the
3256historical information.

3274 5. There are several places where Exim runs a non-Exim command in a
3275 subprocess. The SIGUSR1 signal should be disabled for these processes. This
3276 was being done only for the command run by the queryprogram router. It is
3277 now done for all such subprocesses. The other cases are: ${run, transport
3278 filters, and the commands run by the lmtp and pipe transports.

3280 6. Added CONFIGURE_GROUP build-time option.

3282 7. Some older OS have a limit of 256 on the maximum number of file
3283 descriptors. Exim was using setrlimit() to set 1000 as a large value
3284 unlikely to be exceeded. Change 4.43/17 caused a lot of logging on these
3285 systems. I've change it so that if it can't get 1000, it tries for 256.

3287 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
3288 was an oversight, and furthermore, ever since the addition of extra
3289 controls (e.g. 4.43/32), the checks on when to allow different forms of
3290 "control" were broken. There should now be diagnostics for all cases when a
3291 control that does not make sense is encountered.

3334
333523. When checking ignore_target_hosts for an ipliteral router, no host name was
3336 being passed; this would have caused $sender_host_name to have been used if
3337 matching the list had actually called for a host name (not very likely,
3338 since this list is usually IP addresses). A host name is now passed as
3339 "[x.x.x.x]".

334124. Changed the calls that set up the SIGCHLD handler in the daemon to use the

3344
334525. Narrowed the window for a race in the daemon that could cause it to ignore
3346 SIGCHLD signals. This is not a major problem, because they are used only to
3347 wake it up if nothing else does.

3352 end up negative.

335929. In an address list, if the pattern was not a regular expression, an empty
3360 subject address (from a bounce message) matched only if the pattern was an
3361 empty string. Non-empty patterns were not even tested. This was the wrong
3362 because it is perfectly reasonable to use an empty address as part of a
3363 database query. An empty address is now tested by patterns that are
3364 lookups. However, all the other forms of pattern expect the subject to
3365 contain a local part and a domain, and therefore, for them, an empty
3366 address still always fails if the pattern is not itself empty.

337231. Re-factored the code for checking spool and log partition space into a

337732. The RFC2047 encoding function was originally intended for short strings
3378 such as real names; it was not keeping to the 75-character limit for
3379 encoded words that the RFC imposes. It now respects the limit, and
3380 generates multiple encoded words if necessary. To be on the safe side, I
3381 have increased the buffer size for the ${rfc2047: expansion operator from
3382 1024 to 2048 bytes.
