10JH/02 The smtp transport option "multi_domain" is now expanded.
11
ad07e9ad

12JH/03 The smtp transport now requests PRDR by default, if the server offers
13 it.
14
01a4a5c5
JH
15JH/04 Certificate name checking on server certificates, when exim is a client,
16 is now done by default. The transport option tls_verify_cert_hostname
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18 EXPERIMENTAL_CERTNAMES is withdrawn.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.

JH
22 For GnuTLS, only version 3.0.20 or later.
23
610ff438 24JH/06 Verification of the server certificate for a TLS connection is now tried
6d580f19
JH
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
f926e272
JH
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
35 under the control of the dsn_advertise_hosts option, and routers may
36 have a dsn_lasthop option.
37
0f0c8159
JH
38JH/09 A timeout of 2 minutes is now applied to all malware scanner types by
39 default, modifiable by a malware= option. The list separator for
23763898 40 the options can now be changed in the usual way. Bug 68.

57 now supports optional time-restrictions, weighting, and backup-only
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

78Exim version 4.85
79-----------------
80TL/01 When running the test suite, the README says that variables such as
81 no_msglog_check are global and can be placed anywhere in a specific
82 test's script, however it was observed that placement needed to be near
83 the beginning for it to behave that way. Changed the runtest perl
84 script to read through the entire script once to detect and set these
85 variables, reset to the beginning of the script, and then run through
86 the script parsing/test process like normal.
87
ac20058f
TL
88TL/02 The BSD's have an arc4random API. One of the functions to induce
89 adding randomness was arc4random_stir(), but it has been removed in
90 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
91 function when detected.
92
a9b8ec8b
JH
93JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
94 cause callback expansion.
95
6286d7c4
TL
96TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
97 syntax errors in an expansion can be treated as a string instead of
98 logging or causing an error, due to the internal use of bool_lax
99 instead of bool when processing it.
100
0f06b4f2 101JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
102 server certificates when making smtp deliveries.
103
be36e572
JH
104JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
105

111 Merged patch from Sebastian Wiedenroth.
e449c3b0 112
bd21a787
WB
113JH/05 Fix results-pipe from transport process. Several recipients, combined
114 with certificate use, exposed issues where response data items split
115 over buffer boundaries were not parsed properly. This eventually
116 resulted in duplicates being sent. This issue only became common enough
117 to notice due to the introduction of conection certificate information,
118 the item size being so much larger. Found and fixed by Wolfgang Breyha.
119
8bc732e8
JH
120JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
121 size buffer was used, resulting in syntax errors when an expansion
122 exceeded it.
123
a7fec7a7
JH
124JH/07 Add support for directories of certificates when compiled with a GnuTLS
125 version 3.3.6 or later.
126
774ef2d7
JH
127JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
128 is EXPERIMENTAL_EVENT, the main-configuration and transport options
129 both become "event_action", the variables become $event_name, $event_data
aec45841 130 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
131 routers, transports and related events. The tls:cert event is now also
132 raised for inbound connections, if the main configuration event_action
133 option is defined.
774ef2d7 134
eca4debb
TL
135TL/06 In test suite, disable OCSP for old versions of openssl which contained
136 early OCSP support, but no stapling (appears to be less than 1.0.0).
137
8d692470
JH
138JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
139 server certificate names available under the smtp transport option
140 "tls_verify_cert_hostname" now do not permit multi-component wildcard
141 matches.
142
e9477a08
JH
143JH/10 Time-related extraction expansions from certificates now use the main
144 option "timezone" setting for output formatting, and are consistent
145 between OpenSSL and GnuTLS compilations. Bug 1541.
146
ad4c5ff9
JH
147JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
148 encoded parameter in the incoming message. Bug 1558.
8dea5edf
JH
149
150JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
151 include certificate info, eximon was claiming there were spoolfile
152 syntax errors.
153
3394b36a 154JH/13 Bug 1521: Fix ldap lookup for single-attr request, multiple-attr return.
8dea5edf

156JH/14 Log delivery-related information more consistently, using the sequence
157 "H=<name> [<ip>]" wherever possible.

TL
159TL/07 Bug 1547: Omit RFCs from release. Draft and RFCs have licenses which
160 are problematic for Debian distribution, omit them from the release
161 tarball.

187Exim version 4.83
188-----------------
189
190TF/01 Correctly close the server side of TLS when forking for delivery.
191
192 When a message was received over SMTP with TLS, Exim failed to clear up
193 the incoming connection properly after forking off the child process to
194 deliver the message. In some situations the subsequent outgoing
195 delivery connection happened to have the same fd number as the incoming
196 connection previously had. Exim would try to use TLS and fail, logging
197 a "Bad file descriptor" error.
198

TF
199TF/02 Portability fix for building lookup modules on Solaris when the xpg4
200 utilities have not been installed.
201

202JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
203 temporary space as the ACL may create new global variables.
204

TL
205TL/01 LDAP support uses per connection or global context settings, depending
206 upon the detected version of the libraries at build time.

208TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
209 to extract and use the src ip:port in logging and expansions as if it
8ded8589
TL
210 were a direct connection from the outside internet. PPv2 support was
211 updated based on HAProxy spec change in May 2014.

TL
228 results permerror and temperror. Previous values are deprecated but
229 still accepted. In a future release, err_perm and err_temp will be
230 completely removed, which will be a backward incompatibility if the
231 ACL tests for either of these two old results. Patch contributed by
8ddef691 232 user bes-internal on the mailing list.

256JH/12 Expand items in router/transport headers_add or headers_remove lists
257 individually rather than the list as a whole. Bug 1452.
258
259 Required for reasonable handling of multiple headers_ options when
260 they may be empty; requires that headers_remove items with embedded
261 colons must have them doubled (or the list-separator changed).
262

TL
263TL/07 Add new dmarc expansion variable $dmarc_domain_policy to directly

443TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
444
445 When a queue runner is handling a message, Exim first routes the
446 recipient addresses, during which it prunes them based on the retry
447 hints database. After that it attempts to deliver the message to
448 any remaining recipients. It then updates the hints database using
449 the retry rules.
450
451 So if a recipient address works intermittently, it can get repeatedly
452 deferred at routing time. The retry hints record remains fresh so the
453 address never reaches the final cutoff time.
454
455 This is a fairly common occurrence when a user is bumping up against
456 their storage quota. Exim had some logic in its local delivery code
457 to deal with this. However it did not apply to per-recipient defers
458 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
459
1ddeb334
TF
460 This change adds a proper retry rule check during routing so that the
461 final cutoff time is checked against the message's age. We only do
462 this check if there is an address retry record and there is not a
463 domain retry record; this implies that previous attempts to handle
464 the address had the retry_use_local_parts option turned on. We use
465 this as an approximation for the destination being like a local
466 delivery, as in LMTP.
67bd1ab3
TF
467
468 I suspect this new check makes the old local delivery cutoff check
469 redundant, but I have not verified this so I left the code in place.

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

504 Server implementation by Todd Lyons, client by JH.
505 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
506 config variable "prdr_enable" controls whether the server
507 advertises the facility. If the client requests PRDR a new
508 acl_data_smtp_prdr ACL is called once for each recipient, after
509 the body content is received and before the acl_smtp_data ACL.
510 The client is controlled by bolth of: a hosts_try_prdr option
511 on the smtp transport, and the server advertisement.
512 Default client logging of deliveries and rejections involving
513 PRDR are flagged with the string "PRDR".

794
795 The SIGUSR1 handler appends the current process status to the process
796 log which is later printed by exiwhat. It used to use the general
797 purpose logging code to do this, but several functions it calls are
798 not safe for signals.
799
800 The new output code in the SIGUSR1 handler is specific to the process
801 log, and simple enough that it's easy to inspect for signal safety.

814 Exim now checks that the per_* options are used with an update mode that
815 makes sense for the current ACL. For example, when Exim is processing a
816 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
817 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
818 must specify per_mail/readonly. If you omit the update mode it defaults to
819 /leaky where that makes sense (as before) or /readonly where required.
820
821 The /noupdate option is now undocumented but still supported for
822 backwards compatibility. It is equivalent to /readonly except that in
823 ACLs where /readonly is required you may specify /leaky/noupdate or
824 /strict/noupdate which are treated the same as /readonly.
825
826 A useful new feature is the /count= option. This is a generalization
827 of the per_byte option, so that you can measure the throughput of other
828 aggregate values. For example, the per_byte option is now equivalent
829 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
830
831 The per_rcpt option has been generalized using the /count= mechanism
832 (though it's more complicated than the per_byte equivalence). When it is
833 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
834 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
835 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
836 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
837 Note that using per_rcpt with a non-readonly update mode in more than
838 one ACL will cause the recipients to be double-counted. (The per_mail
839 and per_byte options don't have this problem.)
840
841 The handling of very low rates has changed slightly. If the computed rate
842 is less than the event's count (usually one) then this event is the first
843 after a long gap. In this case the rate is set to the same as this event's
844 count, so that the first message of a spam run is counted properly.
845
846 The major new feature is a mechanism for counting the rate of unique
847 events. The new per_addr option counts the number of different
848 recipients that someone has sent messages to in the last time period. It
849 behaves like per_rcpt if all the recipient addresses are different, but
850 duplicate recipient addresses do not increase the measured rate. Like
851 the /count= option this is a general mechanism, so the per_addr option
852 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
853 example, measure the rate that a client uses different sender addresses
854 with the options per_mail/unique=$sender_address. There are further
855 details in the main documentation.

1406 were called 'true' and it seems that C99 defines that as a reserved

1428
6a3bceb1
PH
1429PH/02 When an IPv6 address is converted to a string for single-key lookup
1430 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1431 dots are used instead of colons so that keys in lsearch files need not
1432 contain colons. This was done some time before quoting was made available
1433 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1434 (notated using the quote facility) so as to distinguish them from IPv4
1435 keys. This meant that lookups for IP addresses in host lists did not work
1436 for iplsearch lookups.
1437
1438 This has been fixed by arranging for IPv6 addresses to be expressed with
1439 colons if the lookup type is iplsearch. This is not incompatible, because
1440 previously such lookups could never work.
1441
1442 The situation is now rather anomolous, since one *can* have colons in
1443 ordinary lsearch keys. However, making the change in all cases is
1444 incompatible and would probably break a number of configurations.

1449MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1450 conversion specification without a maximum field width, thereby enabling
1451 a rogue spamd server to cause a buffer overflow. While nobody in their
1452 right mind would setup Exim to query an untrusted spamd server, an
1453 attacker that gains access to a server running spamd could potentially
1454 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1459MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1460 a directory entry by the name of the lookup key. Previously, if a
1461 symlink pointed to a non-existing file or a file in a directory that
1462 Exim lacked permissions to read, a lookup for a key matching that
1463 symlink would fail. Now it is enough that a matching directory entry
1464 exists, symlink or not. (Bugzilla 503.)

PH
1647PH/29 SMTP synchronization checks are implemented when a command is read -
1648 there is a check that no more input is waiting when there shouldn't be
1649 any. However, for some commands, a delay in an ACL can mean that it is
1650 some time before the response is written. In this time, more input might
1651 arrive, invalidly. So now there are extra checks after an ACL has run for
1652 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1653 pipelining has not been advertised.

1668 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1669 was a macro that became an assignment, so it seemed to work. This has
1670 changed to a proper function call with a void return, hence the compile

1702 started the daemon, but after a SIGHUP it used the Exim user (because it
1703 calls itself on a restart). I have changed the code so that it now always
1704 uses the Exim user.

1709 with PIPELINING or a stupid MUA), the error message that was given to the
1710 RCPT commands is included in the rejection of the DATA command. This is
1711 intended to be helpful for MUAs that show only the final error to their

58eb016e 1726PH/44 I found a way to check for a TCP/IP connection going away before sending

PH
1727 the response to the final '.' that terminates a message, but only in the
1728 case where the client has not sent further data following the '.'
1729 (unfortunately, this is allowed). However, in many cases there won't be
1730 any further data because there won't be any more messages to send. A call
1731 to select() can be used: if it shows that the input is "ready", there is
1732 either input waiting, or the socket has been closed. An attempt to read
1733 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1734 would have sent an OK response which the client would never have see.

1742Exim version 4.66
1743-----------------
1744
1745PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1746 fixed by 4.65/MH/01 (is this a record?) are fixed:
1747
1748 (i) An empty string was always treated as zero by the numeric comparison
1749 operators. This behaviour has been restored.
1750
1751 (ii) It is documented that the numeric comparison operators always treat
1752 their arguments as decimal numbers. This was broken in that numbers
1753 starting with 0 were being interpreted as octal.
1754
1755 While fixing these problems I realized that there was another issue that
1756 hadn't been noticed. Values of message_size_limit (both the global option
1757 and the transport option) were treated as octal if they started with 0.
1758 The documentation was vague. These values are now always treated as
1759 decimal, and I will make that clear in the documentation.

1773PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1774 child addresses, Exim now panics and dies. Previously, because the count
1775 is held in a short int, deliveries were likely to be lost. As such a
1776 large number of recipients for a single message is ridiculous
1777 (performance will be very, very poor), I have chosen to impose a limit
1778 rather than extend the field.

1784TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1785 leftover -K file (the existence of which was triggered by #402).

1791 processing considerably. Previous code took too long for large mails,

1793
1794TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1795 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
1803PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1804 callout verification, Exim cached a "reject" for the entire domain. This
1805 is correct for most verifications, but it is not correct for a recipient
1806 verification with use_sender or use_postmaster set, because in that case
1807 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1808 case of MAIL FROM:<> rejection from other early rejections (e.g.
1809 rejection of HELO). When verifying a recipient using a non-null MAIL
1810 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1811 Whatever the result of the callout, the value of the domain cache is
1812 left unchanged (for any other kind of callout, getting as far as trying
1813 RCPT means that the domain itself is ok).

1847PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1848 hostname. This is wrong, because it relates to the incoming message (and
1849 probably the interface on which it is arriving) and not to the outgoing
1850 callout (which could be using a different interface). This has been
1851 changed to use the value of the helo_data option from the smtp transport
1852 instead - this is what is used when a message is actually being sent. If
1853 there is no remote transport (possible with a router that sets up host
1854 addresses), $smtp_active_hostname is used.

14aa5a05 1856PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1857 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1858 (a) The code assumed that strncpy() returns a negative number on buffer
1859 overflow, which isn't the case. Replaced with Exim's string_format()
1860 function.
1861 (b) There were several signed/unsigned issues. I just did the minimum
1862 hacking in of casts. There is scope for a larger refactoring.
1863 (c) The code used strcasecmp() which is not a standard C function.
1864 Replaced with Exim's strcmpic() function.
1865 (d) The code set only $1; it now sets $auth1 as well.
1866 (e) A simple test gave the error "authentication client didn't specify
1867 service in request". It would seem that Dovecot has changed its
1868 interface. Fortunately there's a specification; I followed it and
1869 changed what the client sends and it appears to be working now.

1874PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1875 address A is aliased to B and C, where B exists and C does not. Without
1876 -v the output is "A verified" because verification stops after a
1877 successful redirection if more than one address is generated. However,
1878 with -v the child addresses are also verified. Exim was outputting "A
1879 failed to verify" and then showing the successful verification for C,
1880 with its parentage. It now outputs "B failed to verify", showing B's
1881 parentage before showing the successful verification of C.

1884 look up a TXT record in a specific list after matching in a combined
1885 list.
1886
322050c2
PH
1887PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1888 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1889 they consult the DNS. I had assumed they would set it the way they
1890 wanted; and indeed my experiments on Linux seem to show that in some
1891 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1892 To be on the safe side, however, I have now made the interface to
1893 host_find_byname() similar to host_find_bydns(), with an argument
1894 containing the DNS resolver options. The host_find_byname() function now
1895 sets these options at its start, just as host_find_bydns() does. The smtp
1896 transport options dns_qualify_single and dns_search_parents are passed to
1897 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1898 of host_find_byname() use the default settings of RES_DEFNAMES
1899 (qualify_single) but not RES_DNSRCH (search_parents).

1901PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1902 spool_read_header() do less string testing, by means of a preliminary
1903 switch on the second character of optional "-foo" lines. (This is
1904 overdue, caused by the large number of possibilities that now exist.
1905 Originally there were few.) While I was there, I also converted the
1906 str(n)cmp tests so they don't re-test the leading "-" and the first
1907 character, in the hope this might squeeze out yet more improvement.

PH
1909PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1910 flag allowing group syntax was set by the header_syntax check but not
1911 turned off, possible causing trouble later; (2) The flag was not being
1912 set at all for the header_verify test, causing "group"-style headers to
1913 be rejected. I have now set it in this case, and also caused header_
1914 verify to ignore an empty address taken from a group. While doing this, I
1915 came across some other cases where the code for allowing group syntax
1916 while scanning a header line wasn't quite right (mostly, not resetting
1917 the flag correctly in the right place). These bugs could have caused
1918 trouble for malformed header lines. I hope it is now all correct.

PH
1920PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1921 with the "reply" argument non-NULL. The code, however (which originally
1922 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1923 but it didn't always do it. This confused somebody who was copying the
1924 code for some other use. I have removed all the tests.

PH
1926PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1927 feature that was used to support insecure browsers during the U.S. crypto
1928 embargo. It requires special client support, and Exim is probably the
1929 only MTA that supported it -- and would never use it because real RSA is
1930 always available. This code has been removed, because it had the bad
1931 effect of slowing Exim down by computing (never used) parameters for the
1932 RSA_EXPORT functionality.

1937 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1938 if the connection is using TLS or if the remote IP is the same as the
1939 local IP, and the "valid-client-cert option" if a client certificate has
1940 been verified.

1972PH/30 Exim was sometimes attempting to deliver messages that had suffered
1973 address errors (4xx response to RCPT) over the same connection as other
1974 messages routed to the same hosts. Such deliveries are always "forced",
1975 so retry times are not inspected. This resulted in far too many retries
1976 for the affected addresses. The effect occurred only when there were more
1977 hosts than the hosts_max_try setting in the smtp transport when it had
1978 the 4xx errors. Those hosts that it had tried were not added to the list
1979 of hosts for which the message was waiting, so if all were tried, there
1980 was no problem. Two fixes have been applied:
1981
1982 (i) If there are any address or message errors in an SMTP delivery, none
1983 of the hosts (tried or untried) are now added to the list of hosts
1984 for which the message is waiting, so the message should not be a
1985 candidate for sending over the same connection that was used for a
1986 successful delivery of some other message. This seems entirely
1987 reasonable: after all the message is NOT "waiting for some host".
1988 This is so "obvious" that I'm not sure why it wasn't done
1989 previously. Hope I haven't missed anything, but it can't do any
1990 harm, as the worst effect is to miss an optimization.
1991
1992 (ii) If, despite (i), such a delivery is accidentally attempted, the
1993 routing retry time is respected, so at least it doesn't keep
1994 hammering the server.

2012 removed the panic log writing for the ECONNRESET error when getsockname()

PH
2015PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2016 runs only) independently of the message's sender address. This meant
2017 that, if the 4xx error was in fact related to the sender, a different
2018 message to the same recipient with a different sender could confuse
2019 things. In particualar, this can happen when sending to a greylisting
2020 server, but other circumstances could also provoke similar problems.
2021 I have changed the default so that the retry time for these errors is now
2022 based a combination of the sender and recipient addresses. This change
2023 can be overridden by setting address_retry_include_sender=false in the
2024 smtp transport.

2351 lines in autoreplies, and the decoded form may well be syntactically

2385 autoreply, Exim could try to deliver to a non-existent relative file

2409 in a subprocess such as that created by queryprogram now generate
2410 suitable debugging ouput when -d is set.

2419PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2420 additional section of a DNS packet that returns MX or SRV records.
2421 Instead, it always explicitly searches for A/AAAA records. This avoids
2422 major problems that occur when a DNS server includes only records of one
2423 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2424 fixed another bug: if SRV records were looked up and the corresponding
2425 address records were *not* found in the additional section, the port
2426 values from the SRV records were lost.

PH
2436PH/19 When calculating a retry time, Exim used to measure the "time since
2437 failure" by looking at the "first failed" field in the retry record. Now
2438 it does not use this if it is later than than the arrival time of the
2439 message. Instead it uses the arrival time. This makes for better
2440 behaviour in cases where some deliveries succeed, thus re-setting the
2441 "first failed" field. An example is a quota failure for a huge message
2442 when small messages continue to be delivered. Without this change, the
2443 "time since failure" will always be short, possible causing more frequent
2444 delivery attempts for the huge message than are intended.

PH
2541PH/42 The content-scanning code uses fopen() to create files in which to put
2542 message data. Previously it was not paying any attention to the mode of
2543 the files. Exim runs with umask(0) because the rest of the code creates
2544 files with open(), and sets the required mode explicitly. Thus, these
2545 files were ending up world-writeable. This was not a big issue, because,
2546 being within the spool directory, they were not world-accessible. I have
2547 created a function called modefopen, which takes an additional mode
2548 argument. It sets umask(777), creates the file, chmods it to the required
2549 mode, then resets the umask. All the relevant calls to fopen() in the
2550 content scanning code have been changed to use this function.

2587
2588 (i) Exim was not creating retry information for temporary errors given
2589 for individual recipients after the DATA command when the smtp transport
2590 was used in LMTP mode. This meant that they could be retried too
2591 frequently, and not timed out correctly.
2592
2593 (ii) Exim was setting the flag that allows error details to be returned
2594 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2595 recipients that were returned after the DATA command.
2596
2597PH/53 This is related to PH/52, but is more general: for any failing address,
2598 when detailed error information was permitted to be returned to the
2599 sender, but the error was temporary, then after the final timeout, only
2600 "retry timeout exceeded" was returned. Now it returns the full error as

2672 function verify_get_ident() calls ip_connect() to connect a socket, but
2673 if the "connect()" function timed out, ip_connect() used to close the
2674 socket. However, verify_get_ident() also closes the socket later, and in
2675 between Exim writes to the log, which may get opened at this point. When
2676 the socket was closed in ip_connect(), the log could get the same file
2677 descriptor number as the socket. This naturally causes chaos. The fix is
2678 not to close the socket in ip_connect(); the socket should be closed by
2679 the function that creates it. There was only one place in the code where
2680 this was missing, in the iplookup router, which I don't think anybody now
2681 uses, but I've fixed it anyway.

2741 identical. For example:
2742
2743 Received: from [1.2.3.4] (helo=[1.2.3.4])
2744
2745 However, if the real host name was known, it was omitting the HELO data
2746 if it matched the actual IP address. This has been tidied up so that it
2747 doesn't show the same IP address twice.

2773PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2774 Electronic Mail") by including:
2775
2776 Auto-submitted: auto-generated
2777
2778 in the messages that it generates (bounce messages and others, such as
2779 warnings). In the case of bounce messages for non-SMTP mesages, there was
2780 also a typo: it was using "Auto_submitted" (underscore instead of
2781 hyphen). Since every message generated by Exim is necessarily in response
2782 to another message, thes have all been changed to:
2783
2784 Auto-Submitted: auto-replied
2785
2786 in accordance with these statements in the RFC:
2787
2788 The auto-replied keyword:
2789
2790 - SHOULD be used on messages sent in direct response to another
2791 message by an automatic process,
2792
2793 - MUST NOT be used on manually-generated messages,
2794
2795 - MAY be used on Delivery Status Notifications (DSNs) and Message
2796 Disposition Notifications (MDNs),
2797
2798 - MUST NOT be used on messages generated by automatic or periodic
2799 processes, except for messages which are automatic responses to
2800 other messages.

2836PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2837 canonical form (as documented). However, after a host name lookup from
2838 the IP address, check_host() was doing a simple string comparison with
2839 addresses acquired from the DNS when checking that the found name did
2840 have the original IP as one of its addresses. Since any found IPv6
2841 addresses are likely to be in abbreviated form, the comparison could
2842 fail. Luckily, there already exists a function for doing the comparison
2843 by converting both addresses to binary, so now that is used instead of
2844 the text comparison.

PH
2846PH/20 There was another similar case to PH/19, when a complete host name was

3148PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3149 in the smtp transport. When a block could not be written in a single
3150 write() function, the timeout was being re-applied to each part-write.
3151 This seems wrong - if the receiver was accepting one byte at a time it
3152 would take for ever. The timeout is now adjusted when this happens. It
3153 doesn't have to be particularly precise.

3219PH/15 The code I had for printing potentially long long variables in PH/11
3220 above was not the best (it lost precision). The length of off_t variables
3221 is now inspected at build time, and an appropriate printing format (%ld

PH
3222 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3223 to be "long long int" or "long int". This is needed for the internal
3224 formatting function string_vformat().

3226PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3227 the configuration file to be ":syslog", then the script "guesses" where
3228 the logs files are, rather than using the compiled in default. In our
3229 case the guess is not the same as the compiled default, so the script
3230 suddenly stopped working when I started to use syslog. The patch checks
3231 to see if log_file_path is "". If so, it attempts to read it from exim
3232 with no configuration file to get the compiled in version, before it
3233 falls back to the previous guessing code."

3250 and a new error check for 8bit text in MIME parts. Comparator and

3252 extension, but it is not well tested yet (read: it works for me)."

3282 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3283 picked up on a user's system that detects such things. There doesn't seem
3284 to be a gcc warning option for this - only an attribute that has to be
3285 put on the function's prototype. It seems that in Fedora Core 4 they have
3286 set this on a number of new functions. No doubt there will be more in due
3287 course.

PH
3289PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3290 specify a transport. However, if an address that was verified by such a
3291 router was the subject of a callout, Exim crashed because it tried to
3292 read the rcpt_include_affixes from the non-existent transport. Now it
3293 just assumes that the setting of that option is false. This bug was
3294 introduced by 4.51/PH/31.

3304PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3305 aren't the modern standard, and it seems that some systems' include files
3306 don't always have them. Exim was already checking for some of the newer
3307 ones like T_AAAA, and defining it itself. I've added checks for all the
3308 record types that Exim uses.

3310PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was

3313 data, a new version was generated, as expected. It was only the case of a
3314 non-existent file that was broken.

3325PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3326 the use of a port name that isn't defined in /etc/services) occurred, the

3328 spool, instead of being failed because of the mua_wrapper setting. This
3329 is now fixed, and I tidied up some of the mua_wrapper messages at the
3330 same time.
