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18 EXPERIMENTAL_CERTNAMES is withdrawn.
19
cb1d7830 20JH/05 The value of the tls_verify_certificates smtp transport and main options
0e0f3f56 21 default to the word "system" to access the system default CA bundle.

25 (but not required) by default. The verification status is now logged by
26 default, for both outbound TLS and client-certificate supplying inbound
27 TLS connections
610ff438 28

29JH/07 Changed the default rfc1413 lookup settings to disable calls. Few
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

53JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
54 Patch from Andrew Lewis.
55
fd4d8871 56JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 57 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
58 modifiers per server. Patch originally by <rommer@active.by>.
59
60JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
61 and remote servers. Remote servers can be IPv6 addresses, and

JH
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).

117Exim version 4.85
118-----------------
119TL/01 When running the test suite, the README says that variables such as
120 no_msglog_check are global and can be placed anywhere in a specific
121 test's script, however it was observed that placement needed to be near
122 the beginning for it to behave that way. Changed the runtest perl
123 script to read through the entire script once to detect and set these
124 variables, reset to the beginning of the script, and then run through
125 the script parsing/test process like normal.

TL
127TL/02 The BSD's have an arc4random API. One of the functions to induce
128 adding randomness was arc4random_stir(), but it has been removed in
129 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
130 function when detected.

132JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
133 cause callback expansion.

TL
135TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
136 syntax errors in an expansion can be treated as a string instead of
137 logging or causing an error, due to the internal use of bool_lax
138 instead of bool when processing it.

bd21a787
WB
152JH/05 Fix results-pipe from transport process. Several recipients, combined
153 with certificate use, exposed issues where response data items split
154 over buffer boundaries were not parsed properly. This eventually
155 resulted in duplicates being sent. This issue only became common enough
156 to notice due to the introduction of conection certificate information,
157 the item size being so much larger. Found and fixed by Wolfgang Breyha.
158
8bc732e8
JH
159JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
160 size buffer was used, resulting in syntax errors when an expansion
161 exceeded it.

164 version 3.3.6 or later.
165
774ef2d7
JH
166JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
167 is EXPERIMENTAL_EVENT, the main-configuration and transport options
168 both become "event_action", the variables become $event_name, $event_data
aec45841 169 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
170 routers, transports and related events. The tls:cert event is now also
171 raised for inbound connections, if the main configuration event_action
172 option is defined.

229TF/01 Correctly close the server side of TLS when forking for delivery.
230
231 When a message was received over SMTP with TLS, Exim failed to clear up
232 the incoming connection properly after forking off the child process to
233 deliver the message. In some situations the subsequent outgoing
234 delivery connection happened to have the same fd number as the incoming
235 connection previously had. Exim would try to use TLS and fail, logging
236 a "Bad file descriptor" error.

482TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
483
484 When a queue runner is handling a message, Exim first routes the
485 recipient addresses, during which it prunes them based on the retry
486 hints database. After that it attempts to deliver the message to
487 any remaining recipients. It then updates the hints database using
488 the retry rules.
489
490 So if a recipient address works intermittently, it can get repeatedly
491 deferred at routing time. The retry hints record remains fresh so the
492 address never reaches the final cutoff time.
493
494 This is a fairly common occurrence when a user is bumping up against
495 their storage quota. Exim had some logic in its local delivery code
496 to deal with this. However it did not apply to per-recipient defers
497 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
498
1ddeb334
TF
499 This change adds a proper retry rule check during routing so that the
500 final cutoff time is checked against the message's age. We only do
501 this check if there is an address retry record and there is not a
502 domain retry record; this implies that previous attempts to handle
503 the address had the retry_use_local_parts option turned on. We use
504 this as an approximation for the destination being like a local
505 delivery, as in LMTP.
67bd1ab3
TF
506
507 I suspect this new check makes the old local delivery cutoff check
508 redundant, but I have not verified this so I left the code in place.

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

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

830TF/03 Make the exiwhat support code safe for signals. Previously Exim might
831 lock up or crash if it happened to be inside a call to libc when it
832 got a SIGUSR1 from exiwhat.
833
834 The SIGUSR1 handler appends the current process status to the process
835 log which is later printed by exiwhat. It used to use the general
836 purpose logging code to do this, but several functions it calls are
837 not safe for signals.
838
839 The new output code in the SIGUSR1 handler is specific to the process
840 log, and simple enough that it's easy to inspect for signal safety.
841 Removing some special cases also simplifies the general logging code.
842 Removing the spurious timestamps from the process log simplifies
843 exiwhat.

845TF/04 Improved ratelimit ACL condition.
846
847 The /noupdate option has been deprecated in favour of /readonly which
848 has clearer semantics. The /leaky, /strict, and /readonly update modes
849 are mutually exclusive. The update mode is no longer included in the
850 database key; it just determines when the database is updated. (This
851 means that when you upgrde Exim will forget old rate measurements.)
852
853 Exim now checks that the per_* options are used with an update mode that
854 makes sense for the current ACL. For example, when Exim is processing a
855 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
856 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
857 must specify per_mail/readonly. If you omit the update mode it defaults to
858 /leaky where that makes sense (as before) or /readonly where required.
859
860 The /noupdate option is now undocumented but still supported for
861 backwards compatibility. It is equivalent to /readonly except that in
862 ACLs where /readonly is required you may specify /leaky/noupdate or
863 /strict/noupdate which are treated the same as /readonly.
864
865 A useful new feature is the /count= option. This is a generalization
866 of the per_byte option, so that you can measure the throughput of other
867 aggregate values. For example, the per_byte option is now equivalent
868 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
869
870 The per_rcpt option has been generalized using the /count= mechanism
871 (though it's more complicated than the per_byte equivalence). When it is
872 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
873 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
874 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
875 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
876 Note that using per_rcpt with a non-readonly update mode in more than
877 one ACL will cause the recipients to be double-counted. (The per_mail
878 and per_byte options don't have this problem.)
879
880 The handling of very low rates has changed slightly. If the computed rate
881 is less than the event's count (usually one) then this event is the first
882 after a long gap. In this case the rate is set to the same as this event's
883 count, so that the first message of a spam run is counted properly.
884
885 The major new feature is a mechanism for counting the rate of unique
886 events. The new per_addr option counts the number of different
887 recipients that someone has sent messages to in the last time period. It
888 behaves like per_rcpt if all the recipient addresses are different, but
889 duplicate recipient addresses do not increase the measured rate. Like
890 the /count= option this is a general mechanism, so the per_addr option
891 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
892 example, measure the rate that a client uses different sender addresses
893 with the options per_mail/unique=$sender_address. There are further
894 details in the main documentation.

1466PH/01 Another patch from the Sieve maintainer.
1467
6a3bceb1
PH
1468PH/02 When an IPv6 address is converted to a string for single-key lookup
1469 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1470 dots are used instead of colons so that keys in lsearch files need not
1471 contain colons. This was done some time before quoting was made available
1472 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1473 (notated using the quote facility) so as to distinguish them from IPv4
1474 keys. This meant that lookups for IP addresses in host lists did not work
1475 for iplsearch lookups.
1476
1477 This has been fixed by arranging for IPv6 addresses to be expressed with
1478 colons if the lookup type is iplsearch. This is not incompatible, because
1479 previously such lookups could never work.
1480
1481 The situation is now rather anomolous, since one *can* have colons in
1482 ordinary lsearch keys. However, making the change in all cases is
1483 incompatible and would probably break a number of configurations.

MH
1488MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1489 conversion specification without a maximum field width, thereby enabling
1490 a rogue spamd server to cause a buffer overflow. While nobody in their
1491 right mind would setup Exim to query an untrusted spamd server, an
1492 attacker that gains access to a server running spamd could potentially
1493 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1498MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1499 a directory entry by the name of the lookup key. Previously, if a
1500 symlink pointed to a non-existing file or a file in a directory that
1501 Exim lacked permissions to read, a lookup for a key matching that
1502 symlink would fail. Now it is enough that a matching directory entry
1503 exists, symlink or not. (Bugzilla 503.)

PH
1573PH/01 Added a new log selector smtp_no_mail, to log SMTP sessions that do not
1574 issue a MAIL command.
1575
431b7361
PH
1576PH/02 In an ACL statement such as
1577
1578 deny dnslists = X!=127.0.0.2 : X=127.0.0.2
1579
1580 if a client was not listed at all, or was listed with a value other than
1581 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,
1582 the condition was not true (as it should be), so access was not denied.
1583 The bug was that the ! inversion was incorrectly passed on to the second
1584 item. This has been fixed.
1585
1586PH/03 Added additional dnslists conditions == and =& which are different from
1587 = and & when the dns lookup returns more than one IP address.
1588
83da1223
PH
1589PH/04 Added gnutls_require_{kx,mac,protocols} to give more control over the
1590 cipher suites used by GnuTLS. These options are ignored by OpenSSL.
1591
54fc8428
PH
1592PH/05 After discussion on the list, added a compile time option ENABLE_DISABLE_
1593 FSYNC, which compiles an option called disable_fsync that allows for
1594 bypassing fsync(). The documentation is heavily laced with warnings.

PH
1598PH/06 Some tidies to the infrastructure of the Test Suite that is concerned
1599 with the auxiliary C programs that it uses: (1) Arrange for BIND_8_COMPAT
1600 to be defined when compiling on OSX (Darwin); (2) Tidies to the Makefile,
1601 including adding "make clean"; (3) Added -fPIC when compiling the test
1602 dynamically loaded module, to get rid of a warning.
1603
0e8a9471
MH
1604MH/02 Fix for bug #451, causing paniclog entries to be written if a bounce
1605 message fails, move_frozen_messages = true and ignore_bounce_errors_after
1606 = 0s. The bug is otherwise harmless.
1607
f0872424
PH
1608PH/07 There was a bug in the dovecot authenticator such that the value of
1609 $auth1 could be overwritten, and so not correctly preserved, after a
1610 successful authentication. This usually meant that the value preserved by
1611 the server_setid option was incorrect.
1612
b01dd148
PH
1613PH/08 Added $smtp_count_at_connection_start, deliberately with a long name.

1615PH/09 Installed PCRE release 7.0.
1616

PH
1617PH/10 The acl_not_smtp_start ACL was, contrary to the documentation, not being
1618 run for batched SMTP input. It is now run at the start of every message
1619 in the batch. While fixing this I discovered that the process information
1620 (output by running exiwhat) was not always getting set for -bs and -bS
1621 input. This is fixed, and it now also says "batched" for BSMTP.
1622
cf8b11a5
PH
1623PH/11 Added control=no_pipelining.

41c7c167
PH
1625PH/12 Added $sending_ip_address and $sending_port (mostly Magnus Holmgren's
1626 patch, slightly modified), and move the expansion of helo_data till after
1627 the connection is made in the smtp transport (so it can use these
1628 values).

1641 no_callout_flush is set.
1642
09945f1e
PH
1643PH/19 Change 4.64/PH/36 introduced a bug: when address_retry_include_sender
1644 was true (the default) a successful delivery failed to delete the retry
1645 item, thus causing premature timeout of the address. The bug is now
1646 fixed.
1647
c51b8e75
PH
1648PH/20 Added hosts_avoid_pipelining to the smtp transport.

e28326d8
PH
1650PH/21 Long custom messages for fakedefer and fakereject are now split up
1651 into multiline reponses in the same way that messages for "deny" and
1652 other ACL rejections are.
1653

PH
1654PH/22 Applied Jori Hamalainen's speed-up changes and typo fixes to exigrep,
1655 with slight modification.

PH
1657PH/23 Applied sieve patches from the maintainer "tracking the latest notify
1658 draft, changing the syntax and factoring some duplicate code".

PH
1660PH/24 When the log selector "outgoing_port" was set, the port was shown as -1
1661 for deliveries of the second and subsequent messages over the same SMTP
1662 connection.

PH
1664PH/25 Applied Magnus Holmgren's patch for ${addresses, ${map, ${filter, and
1665 ${reduce, with only minor "tidies".

PH
1669PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
1670 expansion side effects.
1671
5a11a7b4
PH
1672PH/27 When a message times out after an over-quota error from an Exim-imposed
1673 quota, the bounce message says "mailbox is full". This message was not
1674 being given when it was a system quota that was exceeded. It now should
1675 be the same.
1676
0e20aff9
MH
1677MH/03 Made $recipients available in local_scan(). local_scan() already has
1678 better access to the recipient list through recipients_list[], but
1679 $recipients can be useful in postmaster-provided expansion strings.
1680
ca86f471
PH
1681PH/28 The $smtp_command and $smtp_command_argument variables were not correct
1682 in the case of a MAIL command with additional options following the
1683 address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
1684 were accidentally chopped off.
1685
a14e5636
PH
1686PH/29 SMTP synchronization checks are implemented when a command is read -
1687 there is a check that no more input is waiting when there shouldn't be
1688 any. However, for some commands, a delay in an ACL can mean that it is
1689 some time before the response is written. In this time, more input might
1690 arrive, invalidly. So now there are extra checks after an ACL has run for
1691 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1692 pipelining has not been advertised.
1693
ec95d1a6
PH
1694PH/30 MH's patch to allow iscntrl() characters to be list separators.
1695
42855d71
PH
1696PH/31 Unlike :fail:, a custom message specified with :defer: was not being
1697 returned in the SMTP response when smtp_return_error_details was false.
1698 This has been fixed.
1699
57c2c631
PH
1700PH/32 Change the Dovecot authenticator to use read() and write() on the socket
1701 instead of the C I/O that was originally supplied, because problems were
1702 reported on Solaris.
1703
58c01c94
PH
1704PH/33 Compile failed with OpenSSL 0.9.8e. This was due to a coding error in
1705 Exim which did not show up earlier: it was assuming that a call to
1706 SSL_CTX_set_info_callback() might give an error value. In fact, there is
1707 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1708 was a macro that became an assignment, so it seemed to work. This has
1709 changed to a proper function call with a void return, hence the compile
1710 error. Exim's code has been fixed.
1711
dee5a20a
PH
1712PH/34 Change HDA_SIZE in oracle.c from 256 to 512. This is needed for 64-bit
1713 cpus.

79749a79
PH
1719PH/37 If a message is not accepted after it has had an id assigned (e.g.
1720 because it turns out to be too big or there is a timeout) there is no
3ce62588
PH
1721 "Completed" line in the log. When some messages of this type were
1722 selected by exigrep, they were listed as "not completed". Others were
1723 picked up by some special patterns. I have improved the selection
1724 criteria to be more general.
79749a79 1725
c456d9bb
PH
1726PH/38 The host_find_failed option in the manualroute router can now be set
1727 to "ignore", to completely ignore a host whose IP address cannot be
1728 found. If all hosts are ignored, the behaviour is controlled by the new
1729 host_all_ignored option.
1730
cd9868ec
PH
1731PH/39 In a list of hosts for manualroute, if one item (either because of multi-
1732 homing or because of multiple MX records with /mx) generated more than
1733 one IP address, and the following item turned out to be the local host,
1734 all the secondary addresses of the first item were incorrectly removed
1735 from the list, along with the local host and any following hosts (which
1736 is what is supposed to happen).
1737
ebeaf996
PH
1738PH/40 When Exim receives a message, it writes the login name, uid, and gid of
1739 whoever called Exim into the -H file. In the case of the daemon it was
1740 behaving confusingly. When first started, it used values for whoever
1741 started the daemon, but after a SIGHUP it used the Exim user (because it
1742 calls itself on a restart). I have changed the code so that it now always
1743 uses the Exim user.
1744
2679d413
PH
1745PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
1746 message are rejected with the same error (e.g. no authentication or bad
1747 sender address), and a DATA command is nevertheless sent (as can happen
1748 with PIPELINING or a stupid MUA), the error message that was given to the
1749 RCPT commands is included in the rejection of the DATA command. This is
1750 intended to be helpful for MUAs that show only the final error to their
1751 users.

1763PH/43 Yet another patch from the Sieve maintainer.
1764
58eb016e 1765PH/44 I found a way to check for a TCP/IP connection going away before sending
563b63fa
PH
1766 the response to the final '.' that terminates a message, but only in the
1767 case where the client has not sent further data following the '.'
1768 (unfortunately, this is allowed). However, in many cases there won't be
1769 any further data because there won't be any more messages to send. A call
1770 to select() can be used: if it shows that the input is "ready", there is
1771 either input waiting, or the socket has been closed. An attempt to read
1772 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1773 would have sent an OK response which the client would never have see.
563b63fa
PH
1774 This could lead to message repetition. This fix should cure that, at
1775 least in a lot of common cases.

1781Exim version 4.66
1782-----------------
1783
1784PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1785 fixed by 4.65/MH/01 (is this a record?) are fixed:
1786
1787 (i) An empty string was always treated as zero by the numeric comparison
1788 operators. This behaviour has been restored.
1789
1790 (ii) It is documented that the numeric comparison operators always treat
1791 their arguments as decimal numbers. This was broken in that numbers
1792 starting with 0 were being interpreted as octal.
1793
1794 While fixing these problems I realized that there was another issue that
1795 hadn't been noticed. Values of message_size_limit (both the global option
1796 and the transport option) were treated as octal if they started with 0.
1797 The documentation was vague. These values are now always treated as
1798 decimal, and I will make that clear in the documentation.

MH
1808MH/01 Don't check that the operands of numeric comparison operators are

4362ff0d
PH
1812PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1813 child addresses, Exim now panics and dies. Previously, because the count
1814 is held in a short int, deliveries were likely to be lost. As such a
1815 large number of recipients for a single message is ridiculous
1816 (performance will be very, very poor), I have chosen to impose a limit
1817 rather than extend the field.

TK
1823TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1824 leftover -K file (the existence of which was triggered by #402).
1825 While we were at it, introduced process PID as part of the -K
1826 filename. This should rule out race conditions when creating
1827 these files.
1828
1829TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1830 processing considerably. Previous code took too long for large mails,
1831 triggering a timeout which in turn triggers #401.
1832
1833TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1834 in the DK code in transports.c. sendfile() is not really portable,
1835 hence the _LINUX specificness.

1836
1837TF/01 In the add_headers option to the mail command in an Exim filter,
1838 there was a bug that Exim would claim a syntax error in any
1839 header after the first one which had an odd number of characters
1840 in the field name.
1841
2b1c6e3a
PH
1842PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1843 callout verification, Exim cached a "reject" for the entire domain. This
1844 is correct for most verifications, but it is not correct for a recipient
1845 verification with use_sender or use_postmaster set, because in that case
1846 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1847 case of MAIL FROM:<> rejection from other early rejections (e.g.
1848 rejection of HELO). When verifying a recipient using a non-null MAIL
1849 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1850 Whatever the result of the callout, the value of the domain cache is
1851 left unchanged (for any other kind of callout, getting as far as trying
1852 RCPT means that the domain itself is ok).

1857PH/03 On Solaris, an unexpectedly close socket (dropped connection) can

1886PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1887 hostname. This is wrong, because it relates to the incoming message (and
1888 probably the interface on which it is arriving) and not to the outgoing
1889 callout (which could be using a different interface). This has been
1890 changed to use the value of the helo_data option from the smtp transport
1891 instead - this is what is used when a message is actually being sent. If
1892 there is no remote transport (possible with a router that sets up host
1893 addresses), $smtp_active_hostname is used.
6ea85e9a 1894
14aa5a05 1895PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1896 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1897 (a) The code assumed that strncpy() returns a negative number on buffer
1898 overflow, which isn't the case. Replaced with Exim's string_format()
1899 function.
1900 (b) There were several signed/unsigned issues. I just did the minimum
1901 hacking in of casts. There is scope for a larger refactoring.
1902 (c) The code used strcasecmp() which is not a standard C function.
1903 Replaced with Exim's strcmpic() function.
1904 (d) The code set only $1; it now sets $auth1 as well.
1905 (e) A simple test gave the error "authentication client didn't specify
1906 service in request". It would seem that Dovecot has changed its
1907 interface. Fortunately there's a specification; I followed it and
1908 changed what the client sends and it appears to be working now.

PH
1913PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1914 address A is aliased to B and C, where B exists and C does not. Without
1915 -v the output is "A verified" because verification stops after a
1916 successful redirection if more than one address is generated. However,
1917 with -v the child addresses are also verified. Exim was outputting "A
1918 failed to verify" and then showing the successful verification for C,
1919 with its parentage. It now outputs "B failed to verify", showing B's
1920 parentage before showing the successful verification of C.

1922PH/15 Applied Michael Deutschmann's patch to allow DNS black list processing to
1923 look up a TXT record in a specific list after matching in a combined
1924 list.
1925
322050c2
PH
1926PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1927 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1928 they consult the DNS. I had assumed they would set it the way they
1929 wanted; and indeed my experiments on Linux seem to show that in some
1930 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1931 To be on the safe side, however, I have now made the interface to
1932 host_find_byname() similar to host_find_bydns(), with an argument
1933 containing the DNS resolver options. The host_find_byname() function now
1934 sets these options at its start, just as host_find_bydns() does. The smtp
1935 transport options dns_qualify_single and dns_search_parents are passed to
1936 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1937 of host_find_byname() use the default settings of RES_DEFNAMES
1938 (qualify_single) but not RES_DNSRCH (search_parents).
1939

PH
1940PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1941 spool_read_header() do less string testing, by means of a preliminary
1942 switch on the second character of optional "-foo" lines. (This is
1943 overdue, caused by the large number of possibilities that now exist.
1944 Originally there were few.) While I was there, I also converted the
1945 str(n)cmp tests so they don't re-test the leading "-" and the first
1946 character, in the hope this might squeeze out yet more improvement.
1947

PH
1948PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1949 flag allowing group syntax was set by the header_syntax check but not
1950 turned off, possible causing trouble later; (2) The flag was not being
1951 set at all for the header_verify test, causing "group"-style headers to
1952 be rejected. I have now set it in this case, and also caused header_
1953 verify to ignore an empty address taken from a group. While doing this, I
1954 came across some other cases where the code for allowing group syntax
1955 while scanning a header line wasn't quite right (mostly, not resetting
1956 the flag correctly in the right place). These bugs could have caused
1957 trouble for malformed header lines. I hope it is now all correct.

1959PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1960 with the "reply" argument non-NULL. The code, however (which originally
1961 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1962 but it didn't always do it. This confused somebody who was copying the
1963 code for some other use. I have removed all the tests.

1965PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1966 feature that was used to support insecure browsers during the U.S. crypto
1967 embargo. It requires special client support, and Exim is probably the
1968 only MTA that supported it -- and would never use it because real RSA is
1969 always available. This code has been removed, because it had the bad
1970 effect of slowing Exim down by computing (never used) parameters for the
1971 RSA_EXPORT functionality.

1973PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1976 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1977 if the connection is using TLS or if the remote IP is the same as the
1978 local IP, and the "valid-client-cert option" if a client certificate has
1979 been verified.

2010
2011PH/30 Exim was sometimes attempting to deliver messages that had suffered
2012 address errors (4xx response to RCPT) over the same connection as other
2013 messages routed to the same hosts. Such deliveries are always "forced",
2014 so retry times are not inspected. This resulted in far too many retries
2015 for the affected addresses. The effect occurred only when there were more
2016 hosts than the hosts_max_try setting in the smtp transport when it had
2017 the 4xx errors. Those hosts that it had tried were not added to the list
2018 of hosts for which the message was waiting, so if all were tried, there
2019 was no problem. Two fixes have been applied:
2020
2021 (i) If there are any address or message errors in an SMTP delivery, none
2022 of the hosts (tried or untried) are now added to the list of hosts
2023 for which the message is waiting, so the message should not be a
2024 candidate for sending over the same connection that was used for a
2025 successful delivery of some other message. This seems entirely
2026 reasonable: after all the message is NOT "waiting for some host".
2027 This is so "obvious" that I'm not sure why it wasn't done
2028 previously. Hope I haven't missed anything, but it can't do any
2029 harm, as the worst effect is to miss an optimization.
2030
2031 (ii) If, despite (i), such a delivery is accidentally attempted, the
2032 routing retry time is respected, so at least it doesn't keep
2033 hammering the server.

2048PH/35 The error "getsockname() failed: connection reset by peer" was being
2049 written to the panic log as well as the main log, but it isn't really
2050 panic-worthy as it just means the connection died rather early on. I have
2051 removed the panic log writing for the ECONNRESET error when getsockname()
2052 fails.
2053
48c7f9e2
PH
2054PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2055 runs only) independently of the message's sender address. This meant
2056 that, if the 4xx error was in fact related to the sender, a different
2057 message to the same recipient with a different sender could confuse
2058 things. In particualar, this can happen when sending to a greylisting
2059 server, but other circumstances could also provoke similar problems.
2060 I have changed the default so that the retry time for these errors is now
2061 based a combination of the sender and recipient addresses. This change
2062 can be overridden by setting address_retry_include_sender=false in the
2063 smtp transport.

2361PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2362 folder from quota calculations, a direct delivery into this folder messed
2363 up the contents of the maildirsize file. This was because the regex was
2364 used only to exclude .Trash (or whatever) when the size of the mailbox
2365 was calculated. There was no check that a delivery was happening into an
2366 excluded directory. This bug has been fixed by ignoring all quota

2375PH/01 The code for finding all the local interface addresses on a FreeBSD
2376 system running IPv6 was broken. This may well have applied to all BSD
2377 systems, as well as to others that have similar system calls. The broken
2378 code found IPv4 interfaces correctly, but gave incorrect values for the
2379 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2380 that it would not match correctly against @[] and not recognize the IPv6
2381 addresses as local.

2424 autoreply, Exim could try to deliver to a non-existent relative file

2444 non-existent - all you got was a failure to exec. I have made two
2445 changes:
2446
2447 (a) Failures to set uid/gid, the current directory, or a process leader
2448 in a subprocess such as that created by queryprogram now generate
2449 suitable debugging ouput when -d is set.

2458PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2459 additional section of a DNS packet that returns MX or SRV records.
2460 Instead, it always explicitly searches for A/AAAA records. This avoids
2461 major problems that occur when a DNS server includes only records of one
2462 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2463 fixed another bug: if SRV records were looked up and the corresponding
2464 address records were *not* found in the additional section, the port
2465 values from the SRV records were lost.

2467PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2475PH/19 When calculating a retry time, Exim used to measure the "time since
2476 failure" by looking at the "first failed" field in the retry record. Now
2477 it does not use this if it is later than than the arrival time of the
2478 message. Instead it uses the arrival time. This makes for better
2479 behaviour in cases where some deliveries succeed, thus re-setting the
2480 "first failed" field. An example is a quota failure for a huge message
2481 when small messages continue to be delivered. Without this change, the
2482 "time since failure" will always be short, possible causing more frequent
2483 delivery attempts for the huge message than are intended.

PH
2580PH/42 The content-scanning code uses fopen() to create files in which to put
2581 message data. Previously it was not paying any attention to the mode of
2582 the files. Exim runs with umask(0) because the rest of the code creates
2583 files with open(), and sets the required mode explicitly. Thus, these
2584 files were ending up world-writeable. This was not a big issue, because,
2585 being within the spool directory, they were not world-accessible. I have
2586 created a function called modefopen, which takes an additional mode
2587 argument. It sets umask(777), creates the file, chmods it to the required
2588 mode, then resets the umask. All the relevant calls to fopen() in the
2589 content scanning code have been changed to use this function.

2626
2627 (i) Exim was not creating retry information for temporary errors given
2628 for individual recipients after the DATA command when the smtp transport
2629 was used in LMTP mode. This meant that they could be retried too
2630 frequently, and not timed out correctly.
2631
2632 (ii) Exim was setting the flag that allows error details to be returned
2633 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2634 recipients that were returned after the DATA command.
2635
2636PH/53 This is related to PH/52, but is more general: for any failing address,
2637 when detailed error information was permitted to be returned to the

2711 function verify_get_ident() calls ip_connect() to connect a socket, but
2712 if the "connect()" function timed out, ip_connect() used to close the
2713 socket. However, verify_get_ident() also closes the socket later, and in
2714 between Exim writes to the log, which may get opened at this point. When
2715 the socket was closed in ip_connect(), the log could get the same file
2716 descriptor number as the socket. This naturally causes chaos. The fix is
2717 not to close the socket in ip_connect(); the socket should be closed by
2718 the function that creates it. There was only one place in the code where
2719 this was missing, in the iplookup router, which I don't think anybody now
2720 uses, but I've fixed it anyway.

2733 after to before the (commented out) DNS black list checks.
2734
2735 (2) Add control=submission to the relay_from_hosts and authenticated
2736 clients checks, on the grounds that messages accepted by these
2737 statements are most likely to be submissions.

2739PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2740
2741 (1) Generate an error if the third argument for the ${prvs expansion is
2742 not a single digit.
2743
2744 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2745 string.
2746
2747 (3) Reset the variables that are obtained from the first argument of
2748 ${prvscheck and used in the second argument before leaving the code,
2749 because their memory is reclaimed, so using them afterwards may do
2750 silly things.
2751
2752 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2753 one (it's much easier than Tom thought :-).
2754
2755 (5) Because of (4), we can now allow for the use of $prvscheck_result
2756 inside the third argument.

2765PH/05 When a filter generated an autoreply, the entire To: header line was
2766 quoted in the delivery log line, like this:
2767
2768 => >A.N.Other <ano@some.domain> <original@ddress> ...
2769
2770 This has been changed so that it extracts the operative address. There
2771 may be more than one such address. If so, they are comma-separated, like
2772 this:
2773
2774 => >ano@some.domain,ona@other.domain <original@ddress> ...

PH
2776PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2777 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2778 not being looked up in the rDNS to get a host name, Exim was showing the
2779 IP address twice in Received: lines, even though the IP addresses were
2780 identical. For example:
2781
2782 Received: from [1.2.3.4] (helo=[1.2.3.4])
2783
2784 However, if the real host name was known, it was omitting the HELO data
2785 if it matched the actual IP address. This has been tidied up so that it
2786 doesn't show the same IP address twice.

2812PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2813 Electronic Mail") by including:
2814
2815 Auto-submitted: auto-generated
2816
2817 in the messages that it generates (bounce messages and others, such as
2818 warnings). In the case of bounce messages for non-SMTP mesages, there was
2819 also a typo: it was using "Auto_submitted" (underscore instead of
2820 hyphen). Since every message generated by Exim is necessarily in response
2821 to another message, thes have all been changed to:
2822
2823 Auto-Submitted: auto-replied
2824
2825 in accordance with these statements in the RFC:
2826
2827 The auto-replied keyword:
2828
2829 - SHOULD be used on messages sent in direct response to another
2830 message by an automatic process,
2831
2832 - MUST NOT be used on manually-generated messages,
2833
2834 - MAY be used on Delivery Status Notifications (DSNs) and Message
2835 Disposition Notifications (MDNs),
2836
2837 - MUST NOT be used on messages generated by automatic or periodic
2838 processes, except for messages which are automatic responses to
2839 other messages.

2863 nobody wrote the draft yet. This extension is currently #undef'ed, thus

2875PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2876 canonical form (as documented). However, after a host name lookup from
2877 the IP address, check_host() was doing a simple string comparison with
2878 addresses acquired from the DNS when checking that the found name did
2879 have the original IP as one of its addresses. Since any found IPv6
2880 addresses are likely to be in abbreviated form, the comparison could
2881 fail. Luckily, there already exists a function for doing the comparison
2882 by converting both addresses to binary, so now that is used instead of
2883 the text comparison.
2884
96776534
PH
2885PH/20 There was another similar case to PH/19, when a complete host name was

3143-----------------
3144
3145TF/01 Added support for Client SMTP Authorization. See NewStuff for details.

PH
3147PH/01 When a transport filter timed out in a pipe delivery, and the pipe
3148 command itself ended in error, the underlying message about the transport
3149 filter timeout was being overwritten with the pipe command error. Now the
3150 underlying error message should be appended to the second error message.

3152TK/01 Fix poll() being unavailable on Mac OSX 10.2.
3153

PH
3154PH/02 Reduce the amount of output that "make" produces by default. Full output
3155 can still be requested.
3156
9c7a242c
PH
3157PH/03 The warning log line about a condition test deferring for a "warn" verb
3158 was being output only once per connection, rather than after each
3159 occurrence (because it was using the same function as for successful
3160 "warn" verbs). This seems wrong, so I have changed it.
3161

PH
3162TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3163 it should not have, which might have caused a crash in the right
3164 circumstances, but probably never did.
3165
3166PH/04 Installed a modified version of Tony Finch's patch to make submission
3167 mode fix the return path as well as the Sender: header line, and to
3168 add a /name= option so that you can make the user's friendly name appear
3169 in the header line.
3170

TF
3171TF/03 Added the control = fakedefer ACL modifier.
3172

TF
3173TF/04 Added the ratelimit ACL condition. See NewStuff for details. Thanks to
3174 Mark Lowes for thorough testing.

TK
3176TK/02 Rewrote SPF support to work with libspf2 versions >1.2.0.
3177
3178TK/03 Merged latest SRS patch from Miles Wilton.
3179

PH
3180PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3181 with the definition in sysexits.h (which is #included earlier).
3182 Fortunately, Exim does not actually use EX_OK. The code used to try to
3183 preserve the sysexits.h value, by assumimg that macro definitions were
3184 scanned for macro replacements. I have been disabused of this notion,
3185 so now the code just undefines EX_OK before #including unistd.h.
11d337a4 3186
958541e9
PH
3187PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3188 in the smtp transport. When a block could not be written in a single
3189 write() function, the timeout was being re-applied to each part-write.
3190 This seems wrong - if the receiver was accepting one byte at a time it
3191 would take for ever. The timeout is now adjusted when this happens. It
3192 doesn't have to be particularly precise.
3193

TK
3194TK/04 Added simple SPF lookup method in EXPERIMENTAL_SPF. See NewStuff for
3195 details. Thanks to Chris Webb <chris@arachsys.com> for the patch!
3196
2a4be8f9
PH
3197PH/07 Added "fullpostmaster" verify option, which does a check to <postmaster>
3198 without a domain if the check to <postmaster@domain> fails.

SC
3200SC/01 Eximstats: added -xls and the ability to specify output files
3201 (patch written by Frank Heydlauf).
3202
3203SC/02 Eximstats: use FileHandles for outputing results.
3204
3205SC/03 Eximstats: allow any combination of xls, txt, and html output.
3206
3207SC/04 Eximstats: fixed display of large numbers with -nvr option
3208
3209SC/05 Eximstats: fixed merging of reports with empty tables.
3210
3211SC/06 Eximstats: added the -include_original_destination flag
3212
3213SC/07 Eximstats: removed tabs and trailing whitespace.

TK
3215TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller.
3216
3217TK/06 MBOX spool code: Add real "From " MBOX separator line
3218 so the .eml file is really in mbox format (even though
3219 most programs do not really care). Patch from Alex Miller.
3220
3221TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
3222 The latter is generated from $received_to and is only set if the
3223 message has one envelope recipient. SA can use these headers,
3224 obviously out-of-the-box. Patch from Alex Miller.

PH
3226PH/08 The ${def test on a variable was returning false if the variable's
3227 value was "0", contrary to what the specification has always said!
3228 The result should be true unless the variable is empty.
3229
3230PH/09 The syntax error of a character other than { following "${if
3231 def:variable_name" (after optional whitespace) was not being diagnosed.
3232 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3233 accidental colon was present, for example, could give incorrect results.
3234
0d7eb84a
PH
3235PH/10 Tidied the code in a number of places where the st_size field of a stat()
3236 result is used (not including appendfile, where other changes are about
3237 to be made).
3238
3239PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
3240 This involved changing a lot of size variables from int to off_t. It
3241 should work with maildirs and everything.

3243TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of
3244 spamd dying while we are connected to it.

PH
3249PH/12 Applied Alex Kiernan's patch for the API change for the error callback
3250 function for BDB 4.3.
3251

PH
3252PH/13 Changed auto_thaw such that it does not apply to bounce messages.
3253
8ac170f3
PH
3254PH/14 Imported PCRE 6.0; this was more than just a trivial operation because
3255 the sources for PCRE have been re-arranged and more files are now
3256 involved.
3257
b1c749bb
PH
3258PH/15 The code I had for printing potentially long long variables in PH/11
3259 above was not the best (it lost precision). The length of off_t variables
3260 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3261 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3262 to be "long long int" or "long int". This is needed for the internal
3263 formatting function string_vformat().

PH
3265PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3266 the configuration file to be ":syslog", then the script "guesses" where
3267 the logs files are, rather than using the compiled in default. In our
3268 case the guess is not the same as the compiled default, so the script
3269 suddenly stopped working when I started to use syslog. The patch checks
3270 to see if log_file_path is "". If so, it attempts to read it from exim
3271 with no configuration file to get the compiled in version, before it
3272 falls back to the previous guessing code."
3273
294520c8
TK
3274TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with
3275 implementing BATV in an Exim configuration. See NewStuff for the gory
3276 details.
3277
5bd022fe
PH
3278PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and
3279 Makefile that are specific to HP-UX.
3280
90e9ce59
PH
3281PH/18 If the "use_postmaster" option was set for a recipient callout together
3282 with the "random" option, the postmaster address was used as the MAIL
3283 FROM address for the random test, but not for the subsequent recipient
3284 test. It is now used for both.
3285
5ea81592
PH
3286PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3287 patch removes a few documentation additions to RFC 3028, because the
3288 latest draft now contains them. It adds the new en;ascii-case comparator
3289 and a new error check for 8bit text in MIME parts. Comparator and
3290 require names are now matched exactly. I enabled the subaddress
3291 extension, but it is not well tested yet (read: it works for me)."
3292
c6c2dc1d
PH
3293PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3294 rework some of the code of TK/09 above to avoid the hardwired use of
3295 "%lld" and "long long". Replaced the call to snprintf() with a call to
3296 string_vformat().
3297
fffffe4c
PH
3298PH/21 Added some other messages to those in 4.51/PH/42, namely "All relevant MX
3299 records point to non-existent hosts", "retry timeout exceeded", and
3300 "retry time not reached for any host after a long failure period".
ca02eafb 3301
9a26b6b2
PH
3302PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3303 experimental DomainKeys support:
3304
3305 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3306 (2) On an error such as an illegally used "control", the wrong name for
3307 the control was given.
3308
3309 These problems did NOT occur unless DomainKeys support was compiled.
3310
4aee0225
PH
3311PH/23 Added daemon_startup_retries and daemon_startup_sleep.
3312
32d668a5
PH
3313PH/24 Added ${if match_ip condition.
3314
8187c3f3
PH
3315PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3316 databases so that it will be absolutely obvious if a crash occurs in the
3317 DB library. This is a regular occurrence (often caused by mis-matched
3318 db.h files).
3319
ff790e47 3320PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3321 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3322 picked up on a user's system that detects such things. There doesn't seem
3323 to be a gcc warning option for this - only an attribute that has to be
3324 put on the function's prototype. It seems that in Fedora Core 4 they have
3325 set this on a number of new functions. No doubt there will be more in due
3326 course.
ff790e47 3327
5417f6d1
PH
3328PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3329 specify a transport. However, if an address that was verified by such a
3330 router was the subject of a callout, Exim crashed because it tried to
3331 read the rcpt_include_affixes from the non-existent transport. Now it
3332 just assumes that the setting of that option is false. This bug was
3333 introduced by 4.51/PH/31.
3334
59cf8544
PH
3335PH/28 Changed -d+all to exclude +memory, because that information is very
3336 rarely of interest, but it makes the output a lot bigger. People tend to
3337 do -d+all out of habit.
3338
e7ad8a65
PH
3339PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the
3340 code in os-type was giving problems when libc.so lives in lib64, like on
3341 x86_6
