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18 EXPERIMENTAL_CERTNAMES is withdrawn.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.
4e71661f 41

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

83Exim version 4.85
84-----------------
85TL/01 When running the test suite, the README says that variables such as
86 no_msglog_check are global and can be placed anywhere in a specific
87 test's script, however it was observed that placement needed to be near
88 the beginning for it to behave that way. Changed the runtest perl
89 script to read through the entire script once to detect and set these
90 variables, reset to the beginning of the script, and then run through
91 the script parsing/test process like normal.
92
ac20058f
TL
93TL/02 The BSD's have an arc4random API. One of the functions to induce
94 adding randomness was arc4random_stir(), but it has been removed in
95 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
96 function when detected.
97
a9b8ec8b
JH
98JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
99 cause callback expansion.
100
6286d7c4
TL
101TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
102 syntax errors in an expansion can be treated as a string instead of
103 logging or causing an error, due to the internal use of bool_lax
104 instead of bool when processing it.
105
0f06b4f2 106JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
107 server certificates when making smtp deliveries.
108
be36e572
JH
109JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.

bd21a787
WB
118JH/05 Fix results-pipe from transport process. Several recipients, combined
119 with certificate use, exposed issues where response data items split
120 over buffer boundaries were not parsed properly. This eventually
121 resulted in duplicates being sent. This issue only became common enough
122 to notice due to the introduction of conection certificate information,
123 the item size being so much larger. Found and fixed by Wolfgang Breyha.
124
8bc732e8
JH
125JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
126 size buffer was used, resulting in syntax errors when an expansion
127 exceeded it.
128
a7fec7a7
JH
129JH/07 Add support for directories of certificates when compiled with a GnuTLS
130 version 3.3.6 or later.
131
774ef2d7
JH
132JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
133 is EXPERIMENTAL_EVENT, the main-configuration and transport options
134 both become "event_action", the variables become $event_name, $event_data
aec45841 135 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
136 routers, transports and related events. The tls:cert event is now also
137 raised for inbound connections, if the main configuration event_action
138 option is defined.
774ef2d7 139
eca4debb
TL
140TL/06 In test suite, disable OCSP for old versions of openssl which contained
141 early OCSP support, but no stapling (appears to be less than 1.0.0).
142
8d692470
JH
143JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
144 server certificate names available under the smtp transport option
145 "tls_verify_cert_hostname" now do not permit multi-component wildcard
146 matches.
147
e9477a08
JH
148JH/10 Time-related extraction expansions from certificates now use the main
149 option "timezone" setting for output formatting, and are consistent
150 between OpenSSL and GnuTLS compilations. Bug 1541.
151
ad4c5ff9
JH
152JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
153 encoded parameter in the incoming message. Bug 1558.
8dea5edf
JH
154
155JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
156 include certificate info, eximon was claiming there were spoolfile
157 syntax errors.
158

192Exim version 4.83
193-----------------
194
195TF/01 Correctly close the server side of TLS when forking for delivery.
196
197 When a message was received over SMTP with TLS, Exim failed to clear up
198 the incoming connection properly after forking off the child process to
199 deliver the message. In some situations the subsequent outgoing
200 delivery connection happened to have the same fd number as the incoming
201 connection previously had. Exim would try to use TLS and fail, logging
202 a "Bad file descriptor" error.
203

204TF/02 Portability fix for building lookup modules on Solaris when the xpg4
205 utilities have not been installed.

213TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
214 to extract and use the src ip:port in logging and expansions as if it
8ded8589

215 were a direct connection from the outside internet. PPv2 support was
216 updated based on HAProxy spec change in May 2014.

TL
233 results permerror and temperror. Previous values are deprecated but
234 still accepted. In a future release, err_perm and err_temp will be
235 completely removed, which will be a backward incompatibility if the
236 ACL tests for either of these two old results. Patch contributed by

261JH/12 Expand items in router/transport headers_add or headers_remove lists
262 individually rather than the list as a whole. Bug 1452.
263
264 Required for reasonable handling of multiple headers_ options when
265 they may be empty; requires that headers_remove items with embedded
266 colons must have them doubled (or the list-separator changed).
267

448TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
449
450 When a queue runner is handling a message, Exim first routes the
451 recipient addresses, during which it prunes them based on the retry
452 hints database. After that it attempts to deliver the message to
453 any remaining recipients. It then updates the hints database using
454 the retry rules.
455
456 So if a recipient address works intermittently, it can get repeatedly
457 deferred at routing time. The retry hints record remains fresh so the
458 address never reaches the final cutoff time.
459
460 This is a fairly common occurrence when a user is bumping up against
461 their storage quota. Exim had some logic in its local delivery code
462 to deal with this. However it did not apply to per-recipient defers
463 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
464
1ddeb334
TF
465 This change adds a proper retry rule check during routing so that the
466 final cutoff time is checked against the message's age. We only do
467 this check if there is an address retry record and there is not a
468 domain retry record; this implies that previous attempts to handle
469 the address had the retry_use_local_parts option turned on. We use
470 this as an approximation for the destination being like a local
471 delivery, as in LMTP.
67bd1ab3
TF
472
473 I suspect this new check makes the old local delivery cutoff check
474 redundant, but I have not verified this so I left the code in place.

484 a Resent-Sender: header. It erroneously treats any prefix of the
485 username as equal to the username.

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

803 not safe for signals.
804
805 The new output code in the SIGUSR1 handler is specific to the process
806 log, and simple enough that it's easy to inspect for signal safety.

814 has clearer semantics. The /leaky, /strict, and /readonly update modes
815 are mutually exclusive. The update mode is no longer included in the
816 database key; it just determines when the database is updated. (This
817 means that when you upgrde Exim will forget old rate measurements.)
818
819 Exim now checks that the per_* options are used with an update mode that
820 makes sense for the current ACL. For example, when Exim is processing a
821 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
822 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
823 must specify per_mail/readonly. If you omit the update mode it defaults to
824 /leaky where that makes sense (as before) or /readonly where required.
825
826 The /noupdate option is now undocumented but still supported for
827 backwards compatibility. It is equivalent to /readonly except that in
828 ACLs where /readonly is required you may specify /leaky/noupdate or
829 /strict/noupdate which are treated the same as /readonly.
830
831 A useful new feature is the /count= option. This is a generalization
832 of the per_byte option, so that you can measure the throughput of other
833 aggregate values. For example, the per_byte option is now equivalent
834 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
835
836 The per_rcpt option has been generalized using the /count= mechanism
837 (though it's more complicated than the per_byte equivalence). When it is
838 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
839 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
840 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
841 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
842 Note that using per_rcpt with a non-readonly update mode in more than
843 one ACL will cause the recipients to be double-counted. (The per_mail
844 and per_byte options don't have this problem.)
845
846 The handling of very low rates has changed slightly. If the computed rate
847 is less than the event's count (usually one) then this event is the first
848 after a long gap. In this case the rate is set to the same as this event's
849 count, so that the first message of a spam run is counted properly.
850
851 The major new feature is a mechanism for counting the rate of unique
852 events. The new per_addr option counts the number of different
853 recipients that someone has sent messages to in the last time period. It
854 behaves like per_rcpt if all the recipient addresses are different, but
855 duplicate recipient addresses do not increase the measured rate. Like
856 the /count= option this is a general mechanism, so the per_addr option
857 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
858 example, measure the rate that a client uses different sender addresses
859 with the options per_mail/unique=$sender_address. There are further
860 details in the main documentation.

1411 were called 'true' and it seems that C99 defines that as a reserved

1413 not include C99-style headers which use bools without triggering

1432PH/01 Another patch from the Sieve maintainer.
1433
6a3bceb1
PH
1434PH/02 When an IPv6 address is converted to a string for single-key lookup
1435 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1436 dots are used instead of colons so that keys in lsearch files need not
1437 contain colons. This was done some time before quoting was made available
1438 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1439 (notated using the quote facility) so as to distinguish them from IPv4
1440 keys. This meant that lookups for IP addresses in host lists did not work
1441 for iplsearch lookups.
1442
1443 This has been fixed by arranging for IPv6 addresses to be expressed with
1444 colons if the lookup type is iplsearch. This is not incompatible, because
1445 previously such lookups could never work.
1446
1447 The situation is now rather anomolous, since one *can* have colons in
1448 ordinary lsearch keys. However, making the change in all cases is
1449 incompatible and would probably break a number of configurations.

1454MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1455 conversion specification without a maximum field width, thereby enabling
1456 a rogue spamd server to cause a buffer overflow. While nobody in their
1457 right mind would setup Exim to query an untrusted spamd server, an
1458 attacker that gains access to a server running spamd could potentially
1459 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1464MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1465 a directory entry by the name of the lookup key. Previously, if a
1466 symlink pointed to a non-existing file or a file in a directory that
1467 Exim lacked permissions to read, a lookup for a key matching that
1468 symlink would fail. Now it is enough that a matching directory entry
1469 exists, symlink or not. (Bugzilla 503.)

PH
1652PH/29 SMTP synchronization checks are implemented when a command is read -
1653 there is a check that no more input is waiting when there shouldn't be
1654 any. However, for some commands, a delay in an ACL can mean that it is
1655 some time before the response is written. In this time, more input might
1656 arrive, invalidly. So now there are extra checks after an ACL has run for
1657 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1658 pipelining has not been advertised.

1673 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1674 was a macro that became an assignment, so it seemed to work. This has

1707 started the daemon, but after a SIGHUP it used the Exim user (because it

1714 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1732 the response to the final '.' that terminates a message, but only in the
1733 case where the client has not sent further data following the '.'
1734 (unfortunately, this is allowed). However, in many cases there won't be
1735 any further data because there won't be any more messages to send. A call
1736 to select() can be used: if it shows that the input is "ready", there is
1737 either input waiting, or the socket has been closed. An attempt to read
1738 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1739 would have sent an OK response which the client would never have see.

1749
1750PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1751 fixed by 4.65/MH/01 (is this a record?) are fixed:
1752
1753 (i) An empty string was always treated as zero by the numeric comparison
1754 operators. This behaviour has been restored.
1755
1756 (ii) It is documented that the numeric comparison operators always treat
1757 their arguments as decimal numbers. This was broken in that numbers
1758 starting with 0 were being interpreted as octal.
1759
1760 While fixing these problems I realized that there was another issue that
1761 hadn't been noticed. Values of message_size_limit (both the global option
1762 and the transport option) were treated as octal if they started with 0.
1763 The documentation was vague. These values are now always treated as
1764 decimal, and I will make that clear in the documentation.

1778PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1779 child addresses, Exim now panics and dies. Previously, because the count
1780 is held in a short int, deliveries were likely to be lost. As such a
1781 large number of recipients for a single message is ridiculous
1782 (performance will be very, very poor), I have chosen to impose a limit
1783 rather than extend the field.

1789TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1790 leftover -K file (the existence of which was triggered by #402).
1791 While we were at it, introduced process PID as part of the -K

1795TK/02 Bugzilla #402. Apply patch from Simon Arlott, speeding up DK signing
1796 processing considerably. Previous code took too long for large mails,
1797 triggering a timeout which in turn triggers #401.
1798
1799TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used
1800 in the DK code in transports.c. sendfile() is not really portable,

2b1c6e3a
PH
1808PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1809 callout verification, Exim cached a "reject" for the entire domain. This
1810 is correct for most verifications, but it is not correct for a recipient
1811 verification with use_sender or use_postmaster set, because in that case
1812 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1813 case of MAIL FROM:<> rejection from other early rejections (e.g.
1814 rejection of HELO). When verifying a recipient using a non-null MAIL
1815 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1816 Whatever the result of the callout, the value of the domain cache is
1817 left unchanged (for any other kind of callout, getting as far as trying
1818 RCPT means that the domain itself is ok).

1852PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_
1853 hostname. This is wrong, because it relates to the incoming message (and
1854 probably the interface on which it is arriving) and not to the outgoing
1855 callout (which could be using a different interface). This has been
1856 changed to use the value of the helo_data option from the smtp transport
1857 instead - this is what is used when a message is actually being sent. If
1858 there is no remote transport (possible with a router that sets up host
1859 addresses), $smtp_active_hostname is used.

14aa5a05 1861PH/12 Installed Andrey Panin's patch to add a dovecot authenticator. Various
7befa435 1862 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1863 (a) The code assumed that strncpy() returns a negative number on buffer
1864 overflow, which isn't the case. Replaced with Exim's string_format()
1865 function.
1866 (b) There were several signed/unsigned issues. I just did the minimum
1867 hacking in of casts. There is scope for a larger refactoring.
1868 (c) The code used strcasecmp() which is not a standard C function.
1869 Replaced with Exim's strcmpic() function.
1870 (d) The code set only $1; it now sets $auth1 as well.
1871 (e) A simple test gave the error "authentication client didn't specify
1872 service in request". It would seem that Dovecot has changed its
1873 interface. Fortunately there's a specification; I followed it and
1874 changed what the client sends and it appears to be working now.

1879PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1880 address A is aliased to B and C, where B exists and C does not. Without
1881 -v the output is "A verified" because verification stops after a
1882 successful redirection if more than one address is generated. However,
1883 with -v the child addresses are also verified. Exim was outputting "A
1884 failed to verify" and then showing the successful verification for C,
1885 with its parentage. It now outputs "B failed to verify", showing B's
1886 parentage before showing the successful verification of C.

1889 look up a TXT record in a specific list after matching in a combined

1891
322050c2
PH
1892PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1893 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1894 they consult the DNS. I had assumed they would set it the way they
1895 wanted; and indeed my experiments on Linux seem to show that in some
1896 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1897 To be on the safe side, however, I have now made the interface to
1898 host_find_byname() similar to host_find_bydns(), with an argument
1899 containing the DNS resolver options. The host_find_byname() function now
1900 sets these options at its start, just as host_find_bydns() does. The smtp
1901 transport options dns_qualify_single and dns_search_parents are passed to
1902 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1903 of host_find_byname() use the default settings of RES_DEFNAMES
1904 (qualify_single) but not RES_DNSRCH (search_parents).

1906PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1907 spool_read_header() do less string testing, by means of a preliminary
1908 switch on the second character of optional "-foo" lines. (This is
1909 overdue, caused by the large number of possibilities that now exist.
1910 Originally there were few.) While I was there, I also converted the
1911 str(n)cmp tests so they don't re-test the leading "-" and the first
1912 character, in the hope this might squeeze out yet more improvement.

PH
1914PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1915 flag allowing group syntax was set by the header_syntax check but not
1916 turned off, possible causing trouble later; (2) The flag was not being
1917 set at all for the header_verify test, causing "group"-style headers to
1918 be rejected. I have now set it in this case, and also caused header_
1919 verify to ignore an empty address taken from a group. While doing this, I
1920 came across some other cases where the code for allowing group syntax
1921 while scanning a header line wasn't quite right (mostly, not resetting
1922 the flag correctly in the right place). These bugs could have caused
1923 trouble for malformed header lines. I hope it is now all correct.

PH
1925PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1926 with the "reply" argument non-NULL. The code, however (which originally
1927 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1928 but it didn't always do it. This confused somebody who was copying the
1929 code for some other use. I have removed all the tests.

PH
1931PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1932 feature that was used to support insecure browsers during the U.S. crypto
1933 embargo. It requires special client support, and Exim is probably the
1934 only MTA that supported it -- and would never use it because real RSA is
1935 always available. This code has been removed, because it had the bad
1936 effect of slowing Exim down by computing (never used) parameters for the
1937 RSA_EXPORT functionality.

1942 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1943 if the connection is using TLS or if the remote IP is the same as the
1944 local IP, and the "valid-client-cert option" if a client certificate has
1945 been verified.

1977PH/30 Exim was sometimes attempting to deliver messages that had suffered
1978 address errors (4xx response to RCPT) over the same connection as other
1979 messages routed to the same hosts. Such deliveries are always "forced",
1980 so retry times are not inspected. This resulted in far too many retries
1981 for the affected addresses. The effect occurred only when there were more
1982 hosts than the hosts_max_try setting in the smtp transport when it had
1983 the 4xx errors. Those hosts that it had tried were not added to the list
1984 of hosts for which the message was waiting, so if all were tried, there
1985 was no problem. Two fixes have been applied:
1986
1987 (i) If there are any address or message errors in an SMTP delivery, none
1988 of the hosts (tried or untried) are now added to the list of hosts
1989 for which the message is waiting, so the message should not be a
1990 candidate for sending over the same connection that was used for a
1991 successful delivery of some other message. This seems entirely
1992 reasonable: after all the message is NOT "waiting for some host".
1993 This is so "obvious" that I'm not sure why it wasn't done
1994 previously. Hope I haven't missed anything, but it can't do any
1995 harm, as the worst effect is to miss an optimization.
1996
1997 (ii) If, despite (i), such a delivery is accidentally attempted, the
1998 routing retry time is respected, so at least it doesn't keep
1999 hammering the server.

PH
2020PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2021 runs only) independently of the message's sender address. This meant
2022 that, if the 4xx error was in fact related to the sender, a different
2023 message to the same recipient with a different sender could confuse
2024 things. In particualar, this can happen when sending to a greylisting
2025 server, but other circumstances could also provoke similar problems.
2026 I have changed the default so that the retry time for these errors is now
2027 based a combination of the sender and recipient addresses. This change
2028 can be overridden by setting address_retry_include_sender=false in the
2029 smtp transport.

2357 invalid. However, $reply_address has leading white space removed, and all

2390 autoreply, Exim could try to deliver to a non-existent relative file
2391 name, causing unrelated and misleading errors. What now happens is that
2392 it logs this as a hard delivery error, but does not attempt to create a

2412
2413 (a) Failures to set uid/gid, the current directory, or a process leader
2414 in a subprocess such as that created by queryprogram now generate
2415 suitable debugging ouput when -d is set.

2424PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2425 additional section of a DNS packet that returns MX or SRV records.
2426 Instead, it always explicitly searches for A/AAAA records. This avoids
2427 major problems that occur when a DNS server includes only records of one
2428 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2429 fixed another bug: if SRV records were looked up and the corresponding
2430 address records were *not* found in the additional section, the port
2431 values from the SRV records were lost.

PH
2441PH/19 When calculating a retry time, Exim used to measure the "time since
2442 failure" by looking at the "first failed" field in the retry record. Now
2443 it does not use this if it is later than than the arrival time of the
2444 message. Instead it uses the arrival time. This makes for better
2445 behaviour in cases where some deliveries succeed, thus re-setting the
2446 "first failed" field. An example is a quota failure for a huge message
2447 when small messages continue to be delivered. Without this change, the
2448 "time since failure" will always be short, possible causing more frequent
2449 delivery attempts for the huge message than are intended.

PH
2546PH/42 The content-scanning code uses fopen() to create files in which to put
2547 message data. Previously it was not paying any attention to the mode of
2548 the files. Exim runs with umask(0) because the rest of the code creates
2549 files with open(), and sets the required mode explicitly. Thus, these
2550 files were ending up world-writeable. This was not a big issue, because,
2551 being within the spool directory, they were not world-accessible. I have
2552 created a function called modefopen, which takes an additional mode
2553 argument. It sets umask(777), creates the file, chmods it to the required
2554 mode, then resets the umask. All the relevant calls to fopen() in the
2555 content scanning code have been changed to use this function.

2567 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2592
2593 (i) Exim was not creating retry information for temporary errors given
2594 for individual recipients after the DATA command when the smtp transport
2595 was used in LMTP mode. This meant that they could be retried too
2596 frequently, and not timed out correctly.
2597
2598 (ii) Exim was setting the flag that allows error details to be returned
2599 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2600 recipients that were returned after the DATA command.
2601
2602PH/53 This is related to PH/52, but is more general: for any failing address,
2603 when detailed error information was permitted to be returned to the
2604 sender, but the error was temporary, then after the final timeout, only
2605 "retry timeout exceeded" was returned. Now it returns the full error as

2677 function verify_get_ident() calls ip_connect() to connect a socket, but
2678 if the "connect()" function timed out, ip_connect() used to close the
2679 socket. However, verify_get_ident() also closes the socket later, and in
2680 between Exim writes to the log, which may get opened at this point. When
2681 the socket was closed in ip_connect(), the log could get the same file
2682 descriptor number as the socket. This naturally causes chaos. The fix is
2683 not to close the socket in ip_connect(); the socket should be closed by
2684 the function that creates it. There was only one place in the code where
2685 this was missing, in the iplookup router, which I don't think anybody now
2686 uses, but I've fixed it anyway.

2745 IP address twice in Received: lines, even though the IP addresses were
2746 identical. For example:
2747
2748 Received: from [1.2.3.4] (helo=[1.2.3.4])
2749
2750 However, if the real host name was known, it was omitting the HELO data
2751 if it matched the actual IP address. This has been tidied up so that it
2752 doesn't show the same IP address twice.

2778PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2779 Electronic Mail") by including:
2780
2781 Auto-submitted: auto-generated
2782
2783 in the messages that it generates (bounce messages and others, such as
2784 warnings). In the case of bounce messages for non-SMTP mesages, there was
2785 also a typo: it was using "Auto_submitted" (underscore instead of
2786 hyphen). Since every message generated by Exim is necessarily in response
2787 to another message, thes have all been changed to:
2788
2789 Auto-Submitted: auto-replied
2790
2791 in accordance with these statements in the RFC:
2792
2793 The auto-replied keyword:
2794
2795 - SHOULD be used on messages sent in direct response to another
2796 message by an automatic process,
2797
2798 - MUST NOT be used on manually-generated messages,
2799
2800 - MAY be used on Delivery Status Notifications (DSNs) and Message
2801 Disposition Notifications (MDNs),
2802
2803 - MUST NOT be used on messages generated by automatic or periodic
2804 processes, except for messages which are automatic responses to
2805 other messages.

2841PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2842 canonical form (as documented). However, after a host name lookup from
2843 the IP address, check_host() was doing a simple string comparison with
2844 addresses acquired from the DNS when checking that the found name did
2845 have the original IP as one of its addresses. Since any found IPv6
2846 addresses are likely to be in abbreviated form, the comparison could
2847 fail. Luckily, there already exists a function for doing the comparison
2848 by converting both addresses to binary, so now that is used instead of
2849 the text comparison.

PH
2851PH/20 There was another similar case to PH/19, when a complete host name was

3151 so now the code just undefines EX_OK before #including unistd.h.

3153PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3154 in the smtp transport. When a block could not be written in a single
3155 write() function, the timeout was being re-applied to each part-write.
3156 This seems wrong - if the receiver was accepting one byte at a time it
3157 would take for ever. The timeout is now adjusted when this happens. It
3158 doesn't have to be particularly precise.

3183TK/06 MBOX spool code: Add real "From " MBOX separator line

3187TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.

3224PH/15 The code I had for printing potentially long long variables in PH/11
3225 above was not the best (it lost precision). The length of off_t variables
3226 is now inspected at build time, and an appropriate printing format (%ld

PH
3227 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3228 to be "long long int" or "long int". This is needed for the internal
3229 formatting function string_vformat().

3231PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3232 the configuration file to be ":syslog", then the script "guesses" where
3233 the logs files are, rather than using the compiled in default. In our
3234 case the guess is not the same as the compiled default, so the script
3235 suddenly stopped working when I started to use syslog. The patch checks
3236 to see if log_file_path is "". If so, it attempts to read it from exim
3237 with no configuration file to get the compiled in version, before it
3238 falls back to the previous guessing code."

3255 and a new error check for 8bit text in MIME parts. Comparator and

3287 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3288 picked up on a user's system that detects such things. There doesn't seem
3289 to be a gcc warning option for this - only an attribute that has to be
3290 put on the function's prototype. It seems that in Fedora Core 4 they have
3291 set this on a number of new functions. No doubt there will be more in due
3292 course.

PH
3294PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3295 specify a transport. However, if an address that was verified by such a
3296 router was the subject of a callout, Exim crashed because it tried to
3297 read the rcpt_include_affixes from the non-existent transport. Now it
3298 just assumes that the setting of that option is false. This bug was
3299 introduced by 4.51/PH/31.

3309PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3310 aren't the modern standard, and it seems that some systems' include files
3311 don't always have them. Exim was already checking for some of the newer
3312 ones like T_AAAA, and defining it itself. I've added checks for all the
3313 record types that Exim uses.

3315PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3316 not automatically generating a new one, as it is supposed to. This

3318 data, a new version was generated, as expected. It was only the case of a
3319 non-existent file that was broken.
