12JH/03 The smtp transport now requests PRDR by default, if the server offers
13 it.
14
01a4a5c5 15JH/04 Certificate name checking on server certificates, when exim is a client,
b3ef41c9 16 is now done by default. The transport option tls_verify_cert_hostnames
01a4a5c5
JH
17 can be used to disable this per-host. The build option
18 EXPERIMENTAL_CERTNAMES is withdrawn.

30 sites use this now.
31
50dc7409
JH
32JH/08 The EXPERIMENTAL_DSN compile option is no longer needed; all Delivery
33 Status Notification (bounce) messages are now MIME format per RFC 3464.
34 Support for RFC 3461 DSN options NOTIFY,ENVID,RET,ORCPT can be advertised

R
58 modifiers per server. Patch originally by <rommer@active.by>.
59

99JH/28 Bug 1588: Do not use the A lookup following an AAAA for setting the FQDN.
100 Normally benign, it bites when the pair was led to by a CNAME;
101 modern usage is to not canoicalize the domain to a CNAME target
102 (and we were inconsistent anyway for A-only vs AAAA+A).

125Exim version 4.85
126-----------------
127TL/01 When running the test suite, the README says that variables such as
128 no_msglog_check are global and can be placed anywhere in a specific
129 test's script, however it was observed that placement needed to be near
130 the beginning for it to behave that way. Changed the runtest perl
131 script to read through the entire script once to detect and set these
132 variables, reset to the beginning of the script, and then run through
133 the script parsing/test process like normal.

TL
135TL/02 The BSD's have an arc4random API. One of the functions to induce
136 adding randomness was arc4random_stir(), but it has been removed in
137 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
138 function when detected.

JH
140JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
141 cause callback expansion.

TL
143TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
144 syntax errors in an expansion can be treated as a string instead of
145 logging or causing an error, due to the internal use of bool_lax
146 instead of bool when processing it.
147

160JH/05 Fix results-pipe from transport process. Several recipients, combined
161 with certificate use, exposed issues where response data items split
162 over buffer boundaries were not parsed properly. This eventually
163 resulted in duplicates being sent. This issue only became common enough
164 to notice due to the introduction of conection certificate information,
165 the item size being so much larger. Found and fixed by Wolfgang Breyha.
166
8bc732e8
JH
167JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed

JH
174JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
175 is EXPERIMENTAL_EVENT, the main-configuration and transport options
176 both become "event_action", the variables become $event_name, $event_data
aec45841 177 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
178 routers, transports and related events. The tls:cert event is now also
179 raised for inbound connections, if the main configuration event_action
180 option is defined.

237TF/01 Correctly close the server side of TLS when forking for delivery.
238
239 When a message was received over SMTP with TLS, Exim failed to clear up
240 the incoming connection properly after forking off the child process to
241 deliver the message. In some situations the subsequent outgoing
242 delivery connection happened to have the same fd number as the incoming
243 connection previously had. Exim would try to use TLS and fail, logging
244 a "Bad file descriptor" error.

490TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
491
492 When a queue runner is handling a message, Exim first routes the
493 recipient addresses, during which it prunes them based on the retry
494 hints database. After that it attempts to deliver the message to
495 any remaining recipients. It then updates the hints database using
496 the retry rules.
497
498 So if a recipient address works intermittently, it can get repeatedly
499 deferred at routing time. The retry hints record remains fresh so the
500 address never reaches the final cutoff time.
501
502 This is a fairly common occurrence when a user is bumping up against
503 their storage quota. Exim had some logic in its local delivery code
504 to deal with this. However it did not apply to per-recipient defers
505 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
506
1ddeb334
TF
507 This change adds a proper retry rule check during routing so that the
508 final cutoff time is checked against the message's age. We only do
509 this check if there is an address retry record and there is not a
510 domain retry record; this implies that previous attempts to handle
511 the address had the retry_use_local_parts option turned on. We use
512 this as an approximation for the destination being like a local
513 delivery, as in LMTP.
67bd1ab3
TF
514
515 I suspect this new check makes the old local delivery cutoff check
516 redundant, but I have not verified this so I left the code in place.

524 When I ran the test suite under the user fanf2, Exim expanded
525 the header to contain my full name, whereas it should have added
526 a Resent-Sender: header. It erroneously treats any prefix of the
527 username as equal to the username.

551 Server implementation by Todd Lyons, client by JH.
552 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
553 config variable "prdr_enable" controls whether the server
554 advertises the facility. If the client requests PRDR a new
555 acl_data_smtp_prdr ACL is called once for each recipient, after
556 the body content is received and before the acl_smtp_data ACL.
557 The client is controlled by bolth of: a hosts_try_prdr option
558 on the smtp transport, and the server advertisement.
559 Default client logging of deliveries and rejections involving
560 PRDR are flagged with the string "PRDR".

838TF/03 Make the exiwhat support code safe for signals. Previously Exim might
839 lock up or crash if it happened to be inside a call to libc when it
840 got a SIGUSR1 from exiwhat.
841
842 The SIGUSR1 handler appends the current process status to the process
843 log which is later printed by exiwhat. It used to use the general
844 purpose logging code to do this, but several functions it calls are
845 not safe for signals.
846
847 The new output code in the SIGUSR1 handler is specific to the process
848 log, and simple enough that it's easy to inspect for signal safety.
849 Removing some special cases also simplifies the general logging code.
850 Removing the spurious timestamps from the process log simplifies
851 exiwhat.

853TF/04 Improved ratelimit ACL condition.
854
855 The /noupdate option has been deprecated in favour of /readonly which
856 has clearer semantics. The /leaky, /strict, and /readonly update modes
857 are mutually exclusive. The update mode is no longer included in the
858 database key; it just determines when the database is updated. (This
859 means that when you upgrde Exim will forget old rate measurements.)
860
861 Exim now checks that the per_* options are used with an update mode that
862 makes sense for the current ACL. For example, when Exim is processing a
863 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
864 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
865 must specify per_mail/readonly. If you omit the update mode it defaults to
866 /leaky where that makes sense (as before) or /readonly where required.
867
868 The /noupdate option is now undocumented but still supported for
869 backwards compatibility. It is equivalent to /readonly except that in
870 ACLs where /readonly is required you may specify /leaky/noupdate or
871 /strict/noupdate which are treated the same as /readonly.
872
873 A useful new feature is the /count= option. This is a generalization
874 of the per_byte option, so that you can measure the throughput of other
875 aggregate values. For example, the per_byte option is now equivalent
876 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
877
878 The per_rcpt option has been generalized using the /count= mechanism
879 (though it's more complicated than the per_byte equivalence). When it is
880 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
881 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
882 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
883 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
884 Note that using per_rcpt with a non-readonly update mode in more than
885 one ACL will cause the recipients to be double-counted. (The per_mail
886 and per_byte options don't have this problem.)
887
888 The handling of very low rates has changed slightly. If the computed rate
889 is less than the event's count (usually one) then this event is the first
890 after a long gap. In this case the rate is set to the same as this event's
891 count, so that the first message of a spam run is counted properly.
892
893 The major new feature is a mechanism for counting the rate of unique
894 events. The new per_addr option counts the number of different
895 recipients that someone has sent messages to in the last time period. It
896 behaves like per_rcpt if all the recipient addresses are different, but
897 duplicate recipient addresses do not increase the measured rate. Like
898 the /count= option this is a general mechanism, so the per_addr option
899 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
900 example, measure the rate that a client uses different sender addresses
901 with the options per_mail/unique=$sender_address. There are further
902 details in the main documentation.

1473
1474PH/01 Another patch from the Sieve maintainer.
1475
6a3bceb1
PH
1476PH/02 When an IPv6 address is converted to a string for single-key lookup
1477 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1478 dots are used instead of colons so that keys in lsearch files need not
1479 contain colons. This was done some time before quoting was made available
1480 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1481 (notated using the quote facility) so as to distinguish them from IPv4
1482 keys. This meant that lookups for IP addresses in host lists did not work
1483 for iplsearch lookups.
1484
1485 This has been fixed by arranging for IPv6 addresses to be expressed with
1486 colons if the lookup type is iplsearch. This is not incompatible, because
1487 previously such lookups could never work.
1488
1489 The situation is now rather anomolous, since one *can* have colons in
1490 ordinary lsearch keys. However, making the change in all cases is
1491 incompatible and would probably break a number of configurations.

MH
1496MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1497 conversion specification without a maximum field width, thereby enabling
1498 a rogue spamd server to cause a buffer overflow. While nobody in their
1499 right mind would setup Exim to query an untrusted spamd server, an
1500 attacker that gains access to a server running spamd could potentially
1501 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1506MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1507 a directory entry by the name of the lookup key. Previously, if a
1508 symlink pointed to a non-existing file or a file in a directory that
1509 Exim lacked permissions to read, a lookup for a key matching that
1510 symlink would fail. Now it is enough that a matching directory entry
1511 exists, symlink or not. (Bugzilla 503.)

1577MH/01 Fix for bug #448, segfault in Dovecot authenticator when interface_address
1578 is unset (happens when testing with -bh and -oMi isn't used). Thanks to
1579 Jan Srzednicki.

PH
1581PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
1582 issue a MAIL command.

431b7361
PH
1584PH/02 In an ACL statement such as
1585
1586 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1587
1588 if a client was not listed at all, or was listed with a value other than
1589 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1590 the condition was not true (as it should be), so access was not denied.
1591 The bug was that the ! inversion was incorrectly passed on to the second
1592 item. This has been fixed.
1593
1594PH/03 Added additional dnslists conditions == and =& which are different from
1595 = and & when the dns lookup returns more than one IP address.
1596
83da1223
PH
1597PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
1598 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
1599
54fc8428
PH
1600PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
1601 FSYNC, which compiles an option called disable_fsync that allows for
1602 bypassing fsync(). The documentation is heavily laced with warnings.

PH
1606PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
1607 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
1608 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
1609 including adding "make clean"; (3) Added -fPIC when compiling the test
1610 dynamically loaded module, to get rid of a warning.
1611

MH
1612MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
1613 message fails, move_frozen_messages = true and ignore_bounce_errors_after
1614 = 0s. The bug is otherwise harmless.
1615
f0872424
PH
1616PH/07 There was a bug in the dovecot authenticator such that the value of
1617 $auth1 could be overwritten, and so not correctly preserved, after a
1618 successful authentication. This usually meant that the value preserved by
1619 the server_setid option was incorrect.

PH
1625PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1626 run for batched SMTP input. It is now run at the start of every message
1627 in the batch. While fixing this I discovered that the process information
1628 (output by running exiwhat) was not always getting set for -bs and -bS
1629 input. This is fixed, and it now also says "batched" for BSMTP.

1634 patch, slightly modified), and move the expansion of helo_data till after
1635 the connection is made in the smtp transport (so it can use these
1636 values).

PH
1680PH/27 When a message times out after an over-quota error from an Exim-imposed
1681 quota, the bounce message says "mailbox is full". This message was not
1682 being given when it was a system quota that was exceeded. It now should
1683 be the same.

0e20aff9
MH
1685MH/03 Made $recipients available in local_scan(). local_scan() already has
1686 better access to the recipient list through recipients_list[], but
1687 $recipients can be useful in postmaster-provided expansion strings.
1688
ca86f471
PH
1689PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1690 in the case of a MAIL command with additional options following the
1691 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1692 were accidentally chopped off.
1693
a14e5636
PH
1694PH/29 SMTP synchronization checks are implemented when a command is read -
1695 there is a check that no more input is waiting when there shouldn't be
1696 any. However, for some commands, a delay in an ACL can mean that it is
1697 some time before the response is written. In this time, more input might
1698 arrive, invalidly. So now there are extra checks after an ACL has run for
1699 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1700 pipelining has not been advertised.
1701

57c2c631
PH
1708PH/32 Change the Dovecot authenticator to use read() and write() on the socket

1710 reported on Solaris.
1711
58c01c94
PH
1712PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1713 Exim which did not show up earlier: it was assuming that a call to
1714 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1715 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1716 was a macro that became an assignment, so it seemed to work. This has
1717 changed to a proper function call with a void return, hence the compile
1718 error. Exim's code has been fixed.

PH
1729 "Completed" line in the log. When some messages of this type were
1730 selected by exigrep, they were listed as "not completed". Others were

1732 criteria to be more general.

c456d9bb
PH
1734PH/38 The host_find_failed option in the manualroute router can now be set
1735 to "ignore", to completely ignore a host whose IP address cannot be
1736 found. If all hosts are ignored, the behaviour is controlled by the new
1737 host_all_ignored option.
1738
cd9868ec
PH
1739PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1740 homing or because of multiple MX records with /mx) generated more than
1741 one IP address, and the following item turned out to be the local host,
1742 all the secondary addresses of the first item were incorrectly removed
1743 from the list, along with the local host and any following hosts (which
1744 is what is supposed to happen).
1745
ebeaf996
PH
1746PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1747 whoever called Exim into the -H file. In the case of the daemon it was
1748 behaving confusingly. When first started, it used values for whoever
1749 started the daemon, but after a SIGHUP it used the Exim user (because it
1750 calls itself on a restart). I have changed the code so that it now always
1751 uses the Exim user.
1752
2679d413
PH
1753PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1754 message are rejected with the same error (e.g. no authentication or bad
1755 sender address), and a DATA command is nevertheless sent (as can happen
1756 with PIPELINING or a stupid MUA), the error message that was given to the
1757 RCPT commands is included in the rejection of the DATA command. This is
1758 intended to be helpful for MUAs that show only the final error to their
1759 users.

1772
58eb016e 1773PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1774 the response to the final '.' that terminates a message, but only in the
1775 case where the client has not sent further data following the '.'
1776 (unfortunately, this is allowed). However, in many cases there won't be
1777 any further data because there won't be any more messages to send. A call
1778 to select() can be used: if it shows that the input is "ready", there is
1779 either input waiting, or the socket has been closed. An attempt to read
1780 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1781 would have sent an OK response which the client would never have see.
563b63fa

1790-----------------
1791
1792PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1793 fixed by 4.65/MH/01 (is this a record?) are fixed:
1794
1795 (i) An empty string was always treated as zero by the numeric comparison
1796 operators. This behaviour has been restored.
1797
1798 (ii) It is documented that the numeric comparison operators always treat
1799 their arguments as decimal numbers. This was broken in that numbers
1800 starting with 0 were being interpreted as octal.
1801
1802 While fixing these problems I realized that there was another issue that
1803 hadn't been noticed. Values of message_size_limit (both the global option
1804 and the transport option) were treated as octal if they started with 0.
1805 The documentation was vague. These values are now always treated as
1806 decimal, and I will make that clear in the documentation.

MH

4362ff0d
PH
1820PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1821 child addresses, Exim now panics and dies. Previously, because the count
1822 is held in a short int, deliveries were likely to be lost. As such a
1823 large number of recipients for a single message is ridiculous
1824 (performance will be very, very poor), I have chosen to impose a limit
1825 rather than extend the field.

TK
1831TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1832 leftover -K file (the existence of which was triggered by #402).
1833 While we were at it, introduced process PID as part of the -K
1834 filename. This should rule out race conditions when creating
1835 these files.
1836
1837TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1838 processing considerably. Previous code took too long for large mails,
1839 triggering a timeout which in turn triggers #401.
1840
1841TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1842 in the DK code in transports.c. sendfile() is not really portable,
1843 hence the _LINUX specificness.

1845TF/01 In the add_headers option to the mail command in an Exim filter,

1848 in the field name.
1849
2b1c6e3a
PH
1850PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1851 callout verification, Exim cached a "reject" for the entire domain. This
1852 is correct for most verifications, but it is not correct for a recipient
1853 verification with use_sender or use_postmaster set, because in that case
1854 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1855 case of MAIL FROM:<> rejection from other early rejections (e.g.
1856 rejection of HELO). When verifying a recipient using a non-null MAIL
1857 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1858 Whatever the result of the callout, the value of the domain cache is
1859 left unchanged (for any other kind of callout, getting as far as trying
1860 RCPT means that the domain itself is ok).

1894PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1895 hostname. This is wrong, because it relates to the incoming message (and
1896 probably the interface on which it is arriving) and not to the outgoing
1897 callout (which could be using a different interface). This has been
1898 changed to use the value of the helo_data option from the smtp transport
1899 instead - this is what is used when a message is actually being sent. If
1900 there is no remote transport (possible with a router that sets up host
1901 addresses), $smtp_active_hostname is used.
6ea85e9a 1902
14aa5a05 1903PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1904 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1905 (a) The code assumed that strncpy() returns a negative number on buffer
1906 overflow, which isn't the case. Replaced with Exim's string_format()
1907 function.
1908 (b) There were several signed/unsigned issues. I just did the minimum
1909 hacking in of casts. There is scope for a larger refactoring.
1910 (c) The code used strcasecmp() which is not a standard C function.
1911 Replaced with Exim's strcmpic() function.
1912 (d) The code set only $1; it now sets $auth1 as well.
1913 (e) A simple test gave the error "authentication client didn't specify
1914 service in request". It would seem that Dovecot has changed its
1915 interface. Fortunately there's a specification; I followed it and
1916 changed what the client sends and it appears to be working now.

PH
1921PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1922 address A is aliased to B and C, where B exists and C does not. Without
1923 -v the output is "A verified" because verification stops after a
1924 successful redirection if more than one address is generated. However,
1925 with -v the child addresses are also verified. Exim was outputting "A
1926 failed to verify" and then showing the successful verification for C,
1927 with its parentage. It now outputs "B failed to verify", showing B's
1928 parentage before showing the successful verification of C.

1930PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1931 look up a TXT record in a specific list after matching in a combined
1932 list.
1933
322050c2
PH
1934PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1935 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1936 they consult the DNS. I had assumed they would set it the way they
1937 wanted; and indeed my experiments on Linux seem to show that in some
1938 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1939 To be on the safe side, however, I have now made the interface to
1940 host_find_byname() similar to host_find_bydns(), with an argument
1941 containing the DNS resolver options. The host_find_byname() function now
1942 sets these options at its start, just as host_find_bydns() does. The smtp
1943 transport options dns_qualify_single and dns_search_parents are passed to
1944 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1945 of host_find_byname() use the default settings of RES_DEFNAMES
1946 (qualify_single) but not RES_DNSRCH (search_parents).

PH
1948PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1949 spool_read_header() do less string testing, by means of a preliminary
1950 switch on the second character of optional "-foo" lines. (This is
1951 overdue, caused by the large number of possibilities that now exist.
1952 Originally there were few.) While I was there, I also converted the
1953 str(n)cmp tests so they don't re-test the leading "-" and the first
1954 character, in the hope this might squeeze out yet more improvement.

1957 flag allowing group syntax was set by the header_syntax check but not
1958 turned off, possible causing trouble later; (2) The flag was not being
1959 set at all for the header_verify test, causing "group"-style headers to
1960 be rejected. I have now set it in this case, and also caused header_
1961 verify to ignore an empty address taken from a group. While doing this, I
1962 came across some other cases where the code for allowing group syntax
1963 while scanning a header line wasn't quite right (mostly, not resetting
1964 the flag correctly in the right place). These bugs could have caused
1965 trouble for malformed header lines. I hope it is now all correct.

1967PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1968 with the "reply" argument non-NULL. The code, however (which originally
1969 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1970 but it didn't always do it. This confused somebody who was copying the
1971 code for some other use. I have removed all the tests.

1973PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1974 feature that was used to support insecure browsers during the U.S. crypto
1975 embargo. It requires special client support, and Exim is probably the
1976 only MTA that supported it -- and would never use it because real RSA is
1977 always available. This code has been removed, because it had the bad
1978 effect of slowing Exim down by computing (never used) parameters for the
1979 RSA_EXPORT functionality.

1981PH/21 On the advice of Timo Sirainen, added a check to the dovecot
1982 authenticator to fail if there's a tab character in the incoming data
1983 (there should never be unless someone is messing about, as it's supposed
1984 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1985 if the connection is using TLS or if the remote IP is the same as the
1986 local IP, and the "valid-client-cert option" if a client certificate has
1987 been verified.

2019PH/30 Exim was sometimes attempting to deliver messages that had suffered
2020 address errors (4xx response to RCPT) over the same connection as other
2021 messages routed to the same hosts. Such deliveries are always "forced",
2022 so retry times are not inspected. This resulted in far too many retries
2023 for the affected addresses. The effect occurred only when there were more
2024 hosts than the hosts_max_try setting in the smtp transport when it had
2025 the 4xx errors. Those hosts that it had tried were not added to the list
2026 of hosts for which the message was waiting, so if all were tried, there
2027 was no problem. Two fixes have been applied:
2028
2029 (i) If there are any address or message errors in an SMTP delivery, none
2030 of the hosts (tried or untried) are now added to the list of hosts
2031 for which the message is waiting, so the message should not be a
2032 candidate for sending over the same connection that was used for a
2033 successful delivery of some other message. This seems entirely
2034 reasonable: after all the message is NOT "waiting for some host".
2035 This is so "obvious" that I'm not sure why it wasn't done
2036 previously. Hope I haven't missed anything, but it can't do any
2037 harm, as the worst effect is to miss an optimization.
2038
2039 (ii) If, despite (i), such a delivery is accidentally attempted, the
2040 routing retry time is respected, so at least it doesn't keep
2041 hammering the server.

2056PH/35 The error "getsockname() failed: connection reset by peer" was being
2057 written to the panic log as well as the main log, but it isn't really
2058 panic-worthy as it just means the connection died rather early on. I have
2059 removed the panic log writing for the ECONNRESET error when getsockname()
2060 fails.
2061
48c7f9e2
PH
2062PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2063 runs only) independently of the message's sender address. This meant
2064 that, if the 4xx error was in fact related to the sender, a different
2065 message to the same recipient with a different sender could confuse
2066 things. In particualar, this can happen when sending to a greylisting
2067 server, but other circumstances could also provoke similar problems.
2068 I have changed the default so that the retry time for these errors is now
2069 based a combination of the sender and recipient addresses. This change
2070 can be overridden by setting address_retry_include_sender=false in the
2071 smtp transport.

2383PH/01 The code for finding all the local interface addresses on a FreeBSD
2384 system running IPv6 was broken. This may well have applied to all BSD
2385 systems, as well as to others that have similar system calls. The broken
2386 code found IPv4 interfaces correctly, but gave incorrect values for the
2387 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2388 that it would not match correctly against @[] and not recognize the IPv6
2389 addresses as local.

2456 in a subprocess such as that created by queryprogram now generate
2457 suitable debugging ouput when -d is set.

2468 Instead, it always explicitly searches for A/AAAA records. This avoids
2469 major problems that occur when a DNS server includes only records of one
2470 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2471 fixed another bug: if SRV records were looked up and the corresponding
2472 address records were *not* found in the additional section, the port
2473 values from the SRV records were lost.

PH
2483PH/19 When calculating a retry time, Exim used to measure the "time since
2484 failure" by looking at the "first failed" field in the retry record. Now
2485 it does not use this if it is later than than the arrival time of the
2486 message. Instead it uses the arrival time. This makes for better
2487 behaviour in cases where some deliveries succeed, thus re-setting the
2488 "first failed" field. An example is a quota failure for a huge message
2489 when small messages continue to be delivered. Without this change, the
2490 "time since failure" will always be short, possible causing more frequent
2491 delivery attempts for the huge message than are intended.

2588PH/42 The content-scanning code uses fopen() to create files in which to put
2589 message data. Previously it was not paying any attention to the mode of
2590 the files. Exim runs with umask(0) because the rest of the code creates
2591 files with open(), and sets the required mode explicitly. Thus, these
2592 files were ending up world-writeable. This was not a big issue, because,
2593 being within the spool directory, they were not world-accessible. I have
2594 created a function called modefopen, which takes an additional mode
2595 argument. It sets umask(777), creates the file, chmods it to the required
2596 mode, then resets the umask. All the relevant calls to fopen() in the

2634
2635 (i) Exim was not creating retry information for temporary errors given

2637 was used in LMTP mode. This meant that they could be retried too
2638 frequently, and not timed out correctly.
2639
2640 (ii) Exim was setting the flag that allows error details to be returned
2641 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2642 recipients that were returned after the DATA command.
2643
2644PH/53 This is related to PH/52, but is more general: for any failing address,
2645 when detailed error information was permitted to be returned to the

2719 function verify_get_ident() calls ip_connect() to connect a socket, but
2720 if the "connect()" function timed out, ip_connect() used to close the
2721 socket. However, verify_get_ident() also closes the socket later, and in
2722 between Exim writes to the log, which may get opened at this point. When
2723 the socket was closed in ip_connect(), the log could get the same file
2724 descriptor number as the socket. This naturally causes chaos. The fix is
2725 not to close the socket in ip_connect(); the socket should be closed by
2726 the function that creates it. There was only one place in the code where
2727 this was missing, in the iplookup router, which I don't think anybody now
2728 uses, but I've fixed it anyway.

2740 (1) Move the checks for relay_from_hosts and authenticated clients from
2741 after to before the (commented out) DNS black list checks.
2742
2743 (2) Add control=submission to the relay_from_hosts and authenticated
2744 clients checks, on the grounds that messages accepted by these
2745 statements are most likely to be submissions.

PH
2747PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2748
2749 (1) Generate an error if the third argument for the ${prvs expansion is
2750 not a single digit.
2751
2752 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2753 string.
2754
2755 (3) Reset the variables that are obtained from the first argument of
2756 ${prvscheck and used in the second argument before leaving the code,
2757 because their memory is reclaimed, so using them afterwards may do
2758 silly things.
2759
2760 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2761 one (it's much easier than Tom thought :-).
2762
2763 (5) Because of (4), we can now allow for the use of $prvscheck_result
2764 inside the third argument.

2773PH/05 When a filter generated an autoreply, the entire To: header line was
2774 quoted in the delivery log line, like this:
2775
2776 => >A.N.Other <ano@some.domain> <original@ddress> ...
2777
2778 This has been changed so that it extracts the operative address. There
2779 may be more than one such address. If so, they are comma-separated, like
2780 this:
2781
2782 => >ano@some.domain,ona@other.domain <original@ddress> ...
2783
82c19f95
PH
2784PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2785 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2786 not being looked up in the rDNS to get a host name, Exim was showing the
2787 IP address twice in Received: lines, even though the IP addresses were
2788 identical. For example:
2789
2790 Received: from [1.2.3.4] (helo=[1.2.3.4])
2791
2792 However, if the real host name was known, it was omitting the HELO data
2793 if it matched the actual IP address. This has been tidied up so that it
2794 doesn't show the same IP address twice.

PH
2796PH/07 When both +timestamp and +memory debugging was on, the value given by

PH
2820PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2821 Electronic Mail") by including:
2822
2823 Auto-submitted: auto-generated
2824
2825 in the messages that it generates (bounce messages and others, such as
2826 warnings). In the case of bounce messages for non-SMTP mesages, there was
2827 also a typo: it was using "Auto_submitted" (underscore instead of
2828 hyphen). Since every message generated by Exim is necessarily in response
2829 to another message, thes have all been changed to:
2830
2831 Auto-Submitted: auto-replied
2832
2833 in accordance with these statements in the RFC:
2834
2835 The auto-replied keyword:
2836
2837 - SHOULD be used on messages sent in direct response to another
2838 message by an automatic process,
2839
2840 - MUST NOT be used on manually-generated messages,
2841
2842 - MAY be used on Delivery Status Notifications (DSNs) and Message
2843 Disposition Notifications (MDNs),
2844
2845 - MUST NOT be used on messages generated by automatic or periodic
2846 processes, except for messages which are automatic responses to
2847 other messages.

2871 nobody wrote the draft yet. This extension is currently #undef'ed, thus
2872 not changing the active code.

PH
2883PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2884 canonical form (as documented). However, after a host name lookup from
2885 the IP address, check_host() was doing a simple string comparison with
2886 addresses acquired from the DNS when checking that the found name did
2887 have the original IP as one of its addresses. Since any found IPv6
2888 addresses are likely to be in abbreviated form, the comparison could
2889 fail. Luckily, there already exists a function for doing the comparison
2890 by converting both addresses to binary, so now that is used instead of
2891 the text comparison.
2892
96776534
PH
2893PH/20 There was another similar case to PH/19, when a complete host name was

3142 if the DNS of the sending site is misconfigured. This is quite a
3143 common situation. This change restores the behaviour of treating a
3144 helo verification defer as a failure.

PH
3155PH/01 When a transport filter timed out in a pipe delivery, and the pipe
3156 command itself ended in error, the underlying message about the transport
3157 filter timeout was being overwritten with the pipe command error. Now the
3158 underlying error message should be appended to the second error message.

PH
3165PH/03 The warning log line about a condition test deferring for a "warn" verb
3166 was being output only once per connection, rather than after each
3167 occurrence (because it was using the same function as for successful
3168 "warn" verbs). This seems wrong, so I have changed it.

PH
3170TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3171 it should not have, which might have caused a crash in the right
3172 circumstances, but probably never did.
3173
3174PH/04 Installed a modified version of Tony Finch's patch to make submission
3175 mode fix the return path as well as the Sender: header line, and to
3176 add a /name= option so that you can make the user's friendly name appear
3177 in the header line.

PH
3188PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3189 with the definition in sysexits.h (which is #included earlier).
3190 Fortunately, Exim does not actually use EX_OK. The code used to try to
3191 preserve the sysexits.h value, by assumimg that macro definitions were
3192 scanned for macro replacements. I have been disabused of this notion,
3193 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 3194
958541e9
PH
3195PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3196 in the smtp transport. When a block could not be written in a single
3197 write() function, the timeout was being re-applied to each part-write.
3198 This seems wrong - if the receiver was accepting one byte at a time it
3199 would take for ever. The timeout is now adjusted when this happens. It
3200 doesn't have to be particularly precise.

3223TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller.
3224
3225TK/06 MBOX spool code: Add real "From " MBOX separator line
3226 so the .eml file is really in mbox format (even though
3227 most programs do not really care). Patch from Alex Miller.
3228
3229TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
3230 The latter is generated from $received_to and is only set if the
3231 message has one envelope recipient. SA can use these headers,
3232 obviously out-of-the-box. Patch from Alex Miller.

3234PH/08 The ${def test on a variable was returning false if the variable's
3235 value was "0", contrary to what the specification has always said!
3236 The result should be true unless the variable is empty.
3237
3238PH/09 The syntax error of a character other than { following "${if
3239 def:variable_name" (after optional whitespace) was not being diagnosed.
3240 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3241 accidental colon was present, for example, could give incorrect results.

3243PH/10 Tidied the code in a number of places where the st_size field of a stat()
3244 result is used (not including appendfile, where other changes are about
3245 to be made).
3246
3247PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
3248 This involved changing a lot of size variables from int to off_t. It

PH
3266PH/15 The code I had for printing potentially long long variables in PH/11
3267 above was not the best (it lost precision). The length of off_t variables
3268 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3269 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3270 to be "long long int" or "long int". This is needed for the internal
3271 formatting function string_vformat().

PH
3273PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3274 the configuration file to be ":syslog", then the script "guesses" where
3275 the logs files are, rather than using the compiled in default. In our
3276 case the guess is not the same as the compiled default, so the script
3277 suddenly stopped working when I started to use syslog. The patch checks
3278 to see if log_file_path is "". If so, it attempts to read it from exim
3279 with no configuration file to get the compiled in version, before it
3280 falls back to the previous guessing code."

PH
3289PH/18 If the "use_postmaster" option was set for a recipient callout together
3290 with the "random" option, the postmaster address was used as the MAIL
3291 FROM address for the random test, but not for the subsequent recipient
3292 test. It is now used for both.

PH
3294PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3295 patch removes a few documentation additions to RFC 3028, because the
3296 latest draft now contains them. It adds the new en;ascii-case comparator
3297 and a new error check for 8bit text in MIME parts. Comparator and
3298 require names are now matched exactly. I enabled the subaddress
3299 extension, but it is not well tested yet (read: it works for me)."

PH
3301PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3302 rework some of the code of TK/09 above to avoid the hardwired use of
3303 "%lld" and "long long". Replaced the call to snprintf() with a call to
3304 string_vformat().

3310PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3311 experimental DomainKeys support:
3312
3313 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3314 (2) On an error such as an illegally used "control", the wrong name for
3315 the control was given.

3317 These problems did NOT occur unless DomainKeys support was compiled.

PH
3323PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3324 databases so that it will be absolutely obvious if a crash occurs in the
3325 DB library. This is a regular occurrence (often caused by mis-matched
3326 db.h files).
3327
ff790e47 3328PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3329 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3330 picked up on a user's system that detects such things. There doesn't seem
3331 to be a gcc warning option for this - only an attribute that has to be
3332 put on the function's prototype. It seems that in Fedora Core 4 they have
3333 set this on a number of new functions. No doubt there will be more in due
3334 course.

PH
3336PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3337 specify a transport. However, if an address that was verified by such a
3338 router was the subject of a callout, Exim crashed because it tried to
3339 read the rcpt_include_affixes from the non-existent transport. Now it
3340 just assumes that the setting of that option is false. This bug was
3341 introduced by 4.51/PH/31.
