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18 EXPERIMENTAL_CERTNAMES is withdrawn.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

80Exim version 4.85
81-----------------
82TL/01 When running the test suite, the README says that variables such as
83 no_msglog_check are global and can be placed anywhere in a specific
84 test's script, however it was observed that placement needed to be near
85 the beginning for it to behave that way. Changed the runtest perl
86 script to read through the entire script once to detect and set these
87 variables, reset to the beginning of the script, and then run through
88 the script parsing/test process like normal.
89
ac20058f
TL
90TL/02 The BSD's have an arc4random API. One of the functions to induce
91 adding randomness was arc4random_stir(), but it has been removed in
92 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
93 function when detected.
94
a9b8ec8b
JH
95JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
96 cause callback expansion.
97
6286d7c4
TL
98TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
99 syntax errors in an expansion can be treated as a string instead of
100 logging or causing an error, due to the internal use of bool_lax
101 instead of bool when processing it.
102
0f06b4f2 103JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
104 server certificates when making smtp deliveries.
105
be36e572
JH
106JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.

bd21a787
WB
115JH/05 Fix results-pipe from transport process. Several recipients, combined
116 with certificate use, exposed issues where response data items split
117 over buffer boundaries were not parsed properly. This eventually
118 resulted in duplicates being sent. This issue only became common enough
119 to notice due to the introduction of conection certificate information,
120 the item size being so much larger. Found and fixed by Wolfgang Breyha.
121
8bc732e8
JH
122JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
123 size buffer was used, resulting in syntax errors when an expansion
124 exceeded it.
125
a7fec7a7
JH
126JH/07 Add support for directories of certificates when compiled with a GnuTLS
127 version 3.3.6 or later.
128
774ef2d7
JH
129JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
130 is EXPERIMENTAL_EVENT, the main-configuration and transport options
131 both become "event_action", the variables become $event_name, $event_data
aec45841 132 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
133 routers, transports and related events. The tls:cert event is now also
134 raised for inbound connections, if the main configuration event_action
135 option is defined.
774ef2d7 136
eca4debb
TL
137TL/06 In test suite, disable OCSP for old versions of openssl which contained
138 early OCSP support, but no stapling (appears to be less than 1.0.0).
139
8d692470
JH
140JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
141 server certificate names available under the smtp transport option
142 "tls_verify_cert_hostname" now do not permit multi-component wildcard
143 matches.
144
e9477a08
JH
145JH/10 Time-related extraction expansions from certificates now use the main
146 option "timezone" setting for output formatting, and are consistent
147 between OpenSSL and GnuTLS compilations. Bug 1541.
148
ad4c5ff9
JH
149JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
150 encoded parameter in the incoming message. Bug 1558.
8dea5edf
JH
151
152JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
153 include certificate info, eximon was claiming there were spoolfile
154 syntax errors.
155
3394b36a 156JH/13 Bug 1521: Fix ldap lookup for single-attr request, multiple-attr return.
8dea5edf

159 "H=<name> [<ip>]" wherever possible.

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

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

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

207TL/01 LDAP support uses per connection or global context settings, depending
208 upon the detected version of the libraries at build time.

210TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
211 to extract and use the src ip:port in logging and expansions as if it
8ded8589

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

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

258JH/12 Expand items in router/transport headers_add or headers_remove lists
259 individually rather than the list as a whole. Bug 1452.
260
261 Required for reasonable handling of multiple headers_ options when
262 they may be empty; requires that headers_remove items with embedded
263 colons must have them doubled (or the list-separator changed).
264

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

480 the header to contain my full name, whereas it should have added
481 a Resent-Sender: header. It erroneously treats any prefix of the
482 username as equal to the username.

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

799 purpose logging code to do this, but several functions it calls are
800 not safe for signals.
801
802 The new output code in the SIGUSR1 handler is specific to the process
803 log, and simple enough that it's easy to inspect for signal safety.

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

1408 were called 'true' and it seems that C99 defines that as a reserved

1410 not include C99-style headers which use bools without triggering

1429PH/01 Another patch from the Sieve maintainer.
1430
6a3bceb1
PH
1431PH/02 When an IPv6 address is converted to a string for single-key lookup
1432 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1433 dots are used instead of colons so that keys in lsearch files need not
1434 contain colons. This was done some time before quoting was made available
1435 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1436 (notated using the quote facility) so as to distinguish them from IPv4
1437 keys. This meant that lookups for IP addresses in host lists did not work
1438 for iplsearch lookups.
1439
1440 This has been fixed by arranging for IPv6 addresses to be expressed with
1441 colons if the lookup type is iplsearch. This is not incompatible, because
1442 previously such lookups could never work.
1443
1444 The situation is now rather anomolous, since one *can* have colons in
1445 ordinary lsearch keys. However, making the change in all cases is
1446 incompatible and would probably break a number of configurations.

1451MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1452 conversion specification without a maximum field width, thereby enabling
1453 a rogue spamd server to cause a buffer overflow. While nobody in their
1454 right mind would setup Exim to query an untrusted spamd server, an
1455 attacker that gains access to a server running spamd could potentially
1456 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1461MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1462 a directory entry by the name of the lookup key. Previously, if a
1463 symlink pointed to a non-existing file or a file in a directory that
1464 Exim lacked permissions to read, a lookup for a key matching that
1465 symlink would fail. Now it is enough that a matching directory entry
1466 exists, symlink or not. (Bugzilla 503.)

PH
1649PH/29 SMTP synchronization checks are implemented when a command is read -
1650 there is a check that no more input is waiting when there shouldn't be
1651 any. However, for some commands, a delay in an ACL can mean that it is
1652 some time before the response is written. In this time, more input might
1653 arrive, invalidly. So now there are extra checks after an ACL has run for
1654 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1655 pipelining has not been advertised.

1670 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1671 was a macro that became an assignment, so it seemed to work. This has

1704 started the daemon, but after a SIGHUP it used the Exim user (because it

1711 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1729 the response to the final '.' that terminates a message, but only in the
1730 case where the client has not sent further data following the '.'
1731 (unfortunately, this is allowed). However, in many cases there won't be
1732 any further data because there won't be any more messages to send. A call
1733 to select() can be used: if it shows that the input is "ready", there is
1734 either input waiting, or the socket has been closed. An attempt to read
1735 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1736 would have sent an OK response which the client would never have see.

1746
1747PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1748 fixed by 4.65/MH/01 (is this a record?) are fixed:
1749
1750 (i) An empty string was always treated as zero by the numeric comparison
1751 operators. This behaviour has been restored.
1752
1753 (ii) It is documented that the numeric comparison operators always treat
1754 their arguments as decimal numbers. This was broken in that numbers
1755 starting with 0 were being interpreted as octal.
1756
1757 While fixing these problems I realized that there was another issue that
1758 hadn't been noticed. Values of message_size_limit (both the global option
1759 and the transport option) were treated as octal if they started with 0.
1760 The documentation was vague. These values are now always treated as
1761 decimal, and I will make that clear in the documentation.

1775PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1776 child addresses, Exim now panics and dies. Previously, because the count
1777 is held in a short int, deliveries were likely to be lost. As such a
1778 large number of recipients for a single message is ridiculous
1779 (performance will be very, very poor), I have chosen to impose a limit
1780 rather than extend the field.

1786TK/01 Bugzilla #401. Fix DK spooling code so that it can overwrite a
1787 leftover -K file (the existence of which was triggered by #402).

1795
1796TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1805PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1806 callout verification, Exim cached a "reject" for the entire domain. This
1807 is correct for most verifications, but it is not correct for a recipient
1808 verification with use_sender or use_postmaster set, because in that case
1809 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1810 case of MAIL FROM:<> rejection from other early rejections (e.g.
1811 rejection of HELO). When verifying a recipient using a non-null MAIL
1812 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1813 Whatever the result of the callout, the value of the domain cache is
1814 left unchanged (for any other kind of callout, getting as far as trying
1815 RCPT means that the domain itself is ok).

1849PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1851 probably the interface on which it is arriving) and not to the outgoing
1852 callout (which could be using a different interface). This has been
1853 changed to use the value of the helo_data option from the smtp transport
1854 instead - this is what is used when a message is actually being sent. If
1855 there is no remote transport (possible with a router that sets up host
1856 addresses), $smtp_active_hostname is used.

7befa435 1859 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1860 (a) The code assumed that strncpy() returns a negative number on buffer
1861 overflow, which isn't the case. Replaced with Exim's string_format()
1862 function.
1863 (b) There were several signed/unsigned issues. I just did the minimum
1864 hacking in of casts. There is scope for a larger refactoring.
1865 (c) The code used strcasecmp() which is not a standard C function.
1866 Replaced with Exim's strcmpic() function.
1867 (d) The code set only $1; it now sets $auth1 as well.
1868 (e) A simple test gave the error "authentication client didn't specify
1869 service in request". It would seem that Dovecot has changed its
1870 interface. Fortunately there's a specification; I followed it and
1871 changed what the client sends and it appears to be working now.

1876PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1877 address A is aliased to B and C, where B exists and C does not. Without
1878 -v the output is "A verified" because verification stops after a
1879 successful redirection if more than one address is generated. However,
1880 with -v the child addresses are also verified. Exim was outputting "A
1881 failed to verify" and then showing the successful verification for C,
1882 with its parentage. It now outputs "B failed to verify", showing B's
1883 parentage before showing the successful verification of C.

1886 look up a TXT record in a specific list after matching in a combined

1888
322050c2
PH
1889PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1890 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1891 they consult the DNS. I had assumed they would set it the way they
1892 wanted; and indeed my experiments on Linux seem to show that in some
1893 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1894 To be on the safe side, however, I have now made the interface to
1895 host_find_byname() similar to host_find_bydns(), with an argument
1896 containing the DNS resolver options. The host_find_byname() function now
1897 sets these options at its start, just as host_find_bydns() does. The smtp
1898 transport options dns_qualify_single and dns_search_parents are passed to
1899 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1900 of host_find_byname() use the default settings of RES_DEFNAMES
1901 (qualify_single) but not RES_DNSRCH (search_parents).

1903PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1904 spool_read_header() do less string testing, by means of a preliminary
1905 switch on the second character of optional "-foo" lines. (This is
1906 overdue, caused by the large number of possibilities that now exist.
1907 Originally there were few.) While I was there, I also converted the
1908 str(n)cmp tests so they don't re-test the leading "-" and the first
1909 character, in the hope this might squeeze out yet more improvement.

PH
1911PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1912 flag allowing group syntax was set by the header_syntax check but not
1913 turned off, possible causing trouble later; (2) The flag was not being
1914 set at all for the header_verify test, causing "group"-style headers to
1915 be rejected. I have now set it in this case, and also caused header_
1916 verify to ignore an empty address taken from a group. While doing this, I
1917 came across some other cases where the code for allowing group syntax
1918 while scanning a header line wasn't quite right (mostly, not resetting
1919 the flag correctly in the right place). These bugs could have caused
1920 trouble for malformed header lines. I hope it is now all correct.

PH
1922PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1923 with the "reply" argument non-NULL. The code, however (which originally
1924 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1925 but it didn't always do it. This confused somebody who was copying the
1926 code for some other use. I have removed all the tests.

PH
1928PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1929 feature that was used to support insecure browsers during the U.S. crypto
1930 embargo. It requires special client support, and Exim is probably the
1931 only MTA that supported it -- and would never use it because real RSA is
1932 always available. This code has been removed, because it had the bad
1933 effect of slowing Exim down by computing (never used) parameters for the
1934 RSA_EXPORT functionality.

1939 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1940 if the connection is using TLS or if the remote IP is the same as the
1941 local IP, and the "valid-client-cert option" if a client certificate has
1942 been verified.

1974PH/30 Exim was sometimes attempting to deliver messages that had suffered
1975 address errors (4xx response to RCPT) over the same connection as other
1976 messages routed to the same hosts. Such deliveries are always "forced",
1977 so retry times are not inspected. This resulted in far too many retries
1978 for the affected addresses. The effect occurred only when there were more
1979 hosts than the hosts_max_try setting in the smtp transport when it had
1980 the 4xx errors. Those hosts that it had tried were not added to the list
1981 of hosts for which the message was waiting, so if all were tried, there
1982 was no problem. Two fixes have been applied:
1983
1984 (i) If there are any address or message errors in an SMTP delivery, none
1985 of the hosts (tried or untried) are now added to the list of hosts
1986 for which the message is waiting, so the message should not be a
1987 candidate for sending over the same connection that was used for a
1988 successful delivery of some other message. This seems entirely
1989 reasonable: after all the message is NOT "waiting for some host".
1990 This is so "obvious" that I'm not sure why it wasn't done
1991 previously. Hope I haven't missed anything, but it can't do any
1992 harm, as the worst effect is to miss an optimization.
1993
1994 (ii) If, despite (i), such a delivery is accidentally attempted, the
1995 routing retry time is respected, so at least it doesn't keep
1996 hammering the server.

2011PH/35 The error "getsockname() failed: connection reset by peer" was being
2012 written to the panic log as well as the main log, but it isn't really

2014 removed the panic log writing for the ECONNRESET error when getsockname()
2015 fails.

48c7f9e2
PH
2017PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2018 runs only) independently of the message's sender address. This meant
2019 that, if the 4xx error was in fact related to the sender, a different
2020 message to the same recipient with a different sender could confuse
2021 things. In particualar, this can happen when sending to a greylisting
2022 server, but other circumstances could also provoke similar problems.
2023 I have changed the default so that the retry time for these errors is now
2024 based a combination of the sender and recipient addresses. This change
2025 can be overridden by setting address_retry_include_sender=false in the
2026 smtp transport.

2354 invalid. However, $reply_address has leading white space removed, and all

2387 autoreply, Exim could try to deliver to a non-existent relative file

2389 it logs this as a hard delivery error, but does not attempt to create a

2410 (a) Failures to set uid/gid, the current directory, or a process leader
2411 in a subprocess such as that created by queryprogram now generate
2412 suitable debugging ouput when -d is set.

2421PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2422 additional section of a DNS packet that returns MX or SRV records.
2423 Instead, it always explicitly searches for A/AAAA records. This avoids
2424 major problems that occur when a DNS server includes only records of one
2425 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2426 fixed another bug: if SRV records were looked up and the corresponding
2427 address records were *not* found in the additional section, the port
2428 values from the SRV records were lost.

PH
2438PH/19 When calculating a retry time, Exim used to measure the "time since
2439 failure" by looking at the "first failed" field in the retry record. Now
2440 it does not use this if it is later than than the arrival time of the
2441 message. Instead it uses the arrival time. This makes for better
2442 behaviour in cases where some deliveries succeed, thus re-setting the
2443 "first failed" field. An example is a quota failure for a huge message
2444 when small messages continue to be delivered. Without this change, the
2445 "time since failure" will always be short, possible causing more frequent
2446 delivery attempts for the huge message than are intended.

PH
2543PH/42 The content-scanning code uses fopen() to create files in which to put
2544 message data. Previously it was not paying any attention to the mode of
2545 the files. Exim runs with umask(0) because the rest of the code creates
2546 files with open(), and sets the required mode explicitly. Thus, these
2547 files were ending up world-writeable. This was not a big issue, because,
2548 being within the spool directory, they were not world-accessible. I have
2549 created a function called modefopen, which takes an additional mode
2550 argument. It sets umask(777), creates the file, chmods it to the required
2551 mode, then resets the umask. All the relevant calls to fopen() in the
2552 content scanning code have been changed to use this function.

2589
2590 (i) Exim was not creating retry information for temporary errors given
2591 for individual recipients after the DATA command when the smtp transport
2592 was used in LMTP mode. This meant that they could be retried too
2593 frequently, and not timed out correctly.
2594
2595 (ii) Exim was setting the flag that allows error details to be returned
2596 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2597 recipients that were returned after the DATA command.
2598
2599PH/53 This is related to PH/52, but is more general: for any failing address,
2600 when detailed error information was permitted to be returned to the
2601 sender, but the error was temporary, then after the final timeout, only
2602 "retry timeout exceeded" was returned. Now it returns the full error as

2673PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2674 function verify_get_ident() calls ip_connect() to connect a socket, but
2675 if the "connect()" function timed out, ip_connect() used to close the
2676 socket. However, verify_get_ident() also closes the socket later, and in
2677 between Exim writes to the log, which may get opened at this point. When
2678 the socket was closed in ip_connect(), the log could get the same file
2679 descriptor number as the socket. This naturally causes chaos. The fix is
2680 not to close the socket in ip_connect(); the socket should be closed by
2681 the function that creates it. There was only one place in the code where
2682 this was missing, in the iplookup router, which I don't think anybody now
2683 uses, but I've fixed it anyway.

2742 IP address twice in Received: lines, even though the IP addresses were
2743 identical. For example:
2744
2745 Received: from [1.2.3.4] (helo=[1.2.3.4])
2746
2747 However, if the real host name was known, it was omitting the HELO data
2748 if it matched the actual IP address. This has been tidied up so that it
2749 doesn't show the same IP address twice.

2775PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2776 Electronic Mail") by including:
2777
2778 Auto-submitted: auto-generated
2779
2780 in the messages that it generates (bounce messages and others, such as
2781 warnings). In the case of bounce messages for non-SMTP mesages, there was
2782 also a typo: it was using "Auto_submitted" (underscore instead of
2783 hyphen). Since every message generated by Exim is necessarily in response
2784 to another message, thes have all been changed to:
2785
2786 Auto-Submitted: auto-replied
2787
2788 in accordance with these statements in the RFC:
2789
2790 The auto-replied keyword:
2791
2792 - SHOULD be used on messages sent in direct response to another
2793 message by an automatic process,
2794
2795 - MUST NOT be used on manually-generated messages,
2796
2797 - MAY be used on Delivery Status Notifications (DSNs) and Message
2798 Disposition Notifications (MDNs),
2799
2800 - MUST NOT be used on messages generated by automatic or periodic
2801 processes, except for messages which are automatic responses to
2802 other messages.

2838PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2839 canonical form (as documented). However, after a host name lookup from
2840 the IP address, check_host() was doing a simple string comparison with
2841 addresses acquired from the DNS when checking that the found name did
2842 have the original IP as one of its addresses. Since any found IPv6
2843 addresses are likely to be in abbreviated form, the comparison could
2844 fail. Luckily, there already exists a function for doing the comparison
2845 by converting both addresses to binary, so now that is used instead of
2846 the text comparison.

PH
2848PH/20 There was another similar case to PH/19, when a complete host name was

3148 so now the code just undefines EX_OK before #including unistd.h.

3150PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3151 in the smtp transport. When a block could not be written in a single
3152 write() function, the timeout was being re-applied to each part-write.
3153 This seems wrong - if the receiver was accepting one byte at a time it
3154 would take for ever. The timeout is now adjusted when this happens. It
3155 doesn't have to be particularly precise.

3221PH/15 The code I had for printing potentially long long variables in PH/11

PH
3224 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3225 to be "long long int" or "long int". This is needed for the internal
3226 formatting function string_vformat().

3228PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3229 the configuration file to be ":syslog", then the script "guesses" where
3230 the logs files are, rather than using the compiled in default. In our
3231 case the guess is not the same as the compiled default, so the script
3232 suddenly stopped working when I started to use syslog. The patch checks
3233 to see if log_file_path is "". If so, it attempts to read it from exim
3234 with no configuration file to get the compiled in version, before it
3235 falls back to the previous guessing code."

3252 and a new error check for 8bit text in MIME parts. Comparator and

3284 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3285 picked up on a user's system that detects such things. There doesn't seem
3286 to be a gcc warning option for this - only an attribute that has to be
3287 put on the function's prototype. It seems that in Fedora Core 4 they have
3288 set this on a number of new functions. No doubt there will be more in due
3289 course.

PH
3291PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3292 specify a transport. However, if an address that was verified by such a
3293 router was the subject of a callout, Exim crashed because it tried to
3294 read the rcpt_include_affixes from the non-existent transport. Now it
3295 just assumes that the setting of that option is false. This bug was
3296 introduced by 4.51/PH/31.

3306PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3307 aren't the modern standard, and it seems that some systems' include files
3308 don't always have them. Exim was already checking for some of the newer
3309 ones like T_AAAA, and defining it itself. I've added checks for all the
3310 record types that Exim uses.

3312PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was

3315 data, a new version was generated, as expected. It was only the case of a
3316 non-existent file that was broken.

3332 same time.
