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18 EXPERIMENTAL_CERTNAMES is withdrawn.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

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

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

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
1ad6489e

51 /defer_ok option.
52
c5f280e2
AL
53JH/14 Bug 1573: The spam= ACL condition now additionally supports Rspamd.
54 Patch from Andrew Lewis.
55
fd4d8871 56JH/15 Bug 670: The spamd_address main option (for the spam= ACL condition)
dc7b3d36 57 now supports optional time-restrictions, weighting, and priority
fd4d8871
R
58 modifiers per server. Patch originally by <rommer@active.by>.
59
60JH/16 The spamd_address main option now supports a mixed list of local
2aad5761
JH
61 and remote servers. Remote servers can be IPv6 addresses, and
62 specify a port-range.

98

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

115Exim version 4.85
116-----------------
117TL/01 When running the test suite, the README says that variables such as
118 no_msglog_check are global and can be placed anywhere in a specific
119 test's script, however it was observed that placement needed to be near
120 the beginning for it to behave that way. Changed the runtest perl
121 script to read through the entire script once to detect and set these
122 variables, reset to the beginning of the script, and then run through
123 the script parsing/test process like normal.
124
ac20058f
TL
125TL/02 The BSD's have an arc4random API. One of the functions to induce
126 adding randomness was arc4random_stir(), but it has been removed in
127 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
128 function when detected.
129
a9b8ec8b
JH
130JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
131 cause callback expansion.
132
6286d7c4
TL
133TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
134 syntax errors in an expansion can be treated as a string instead of
135 logging or causing an error, due to the internal use of bool_lax
136 instead of bool when processing it.
137
0f06b4f2 138JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
139 server certificates when making smtp deliveries.

bd21a787
WB
150JH/05 Fix results-pipe from transport process. Several recipients, combined
151 with certificate use, exposed issues where response data items split
152 over buffer boundaries were not parsed properly. This eventually
153 resulted in duplicates being sent. This issue only became common enough
154 to notice due to the introduction of conection certificate information,
155 the item size being so much larger. Found and fixed by Wolfgang Breyha.
156
8bc732e8
JH
157JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
158 size buffer was used, resulting in syntax errors when an expansion
159 exceeded it.
160
a7fec7a7
JH
161JH/07 Add support for directories of certificates when compiled with a GnuTLS
162 version 3.3.6 or later.
163
774ef2d7
JH
164JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
165 is EXPERIMENTAL_EVENT, the main-configuration and transport options
166 both become "event_action", the variables become $event_name, $event_data
aec45841 167 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
168 routers, transports and related events. The tls:cert event is now also
169 raised for inbound connections, if the main configuration event_action
170 option is defined.

172TL/06 In test suite, disable OCSP for old versions of openssl which contained
173 early OCSP support, but no stapling (appears to be less than 1.0.0).

8d692470
JH
175JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
176 server certificate names available under the smtp transport option
177 "tls_verify_cert_hostname" now do not permit multi-component wildcard
178 matches.
179

JH
180JH/10 Time-related extraction expansions from certificates now use the main
181 option "timezone" setting for output formatting, and are consistent
182 between OpenSSL and GnuTLS compilations. Bug 1541.

224Exim version 4.83
225-----------------
226
227TF/01 Correctly close the server side of TLS when forking for delivery.
228
229 When a message was received over SMTP with TLS, Exim failed to clear up
230 the incoming connection properly after forking off the child process to
231 deliver the message. In some situations the subsequent outgoing
232 delivery connection happened to have the same fd number as the incoming
233 connection previously had. Exim would try to use TLS and fail, logging
234 a "Bad file descriptor" error.
235

236TF/02 Portability fix for building lookup modules on Solaris when the xpg4
237 utilities have not been installed.

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

293JH/12 Expand items in router/transport headers_add or headers_remove lists
294 individually rather than the list as a whole. Bug 1452.
295
296 Required for reasonable handling of multiple headers_ options when
297 they may be empty; requires that headers_remove items with embedded

480TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
481
482 When a queue runner is handling a message, Exim first routes the
483 recipient addresses, during which it prunes them based on the retry
484 hints database. After that it attempts to deliver the message to
485 any remaining recipients. It then updates the hints database using
486 the retry rules.
487
488 So if a recipient address works intermittently, it can get repeatedly
489 deferred at routing time. The retry hints record remains fresh so the
490 address never reaches the final cutoff time.
491
492 This is a fairly common occurrence when a user is bumping up against
493 their storage quota. Exim had some logic in its local delivery code
494 to deal with this. However it did not apply to per-recipient defers
495 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
496
1ddeb334
TF
497 This change adds a proper retry rule check during routing so that the
498 final cutoff time is checked against the message's age. We only do
499 this check if there is an address retry record and there is not a
500 domain retry record; this implies that previous attempts to handle
501 the address had the retry_use_local_parts option turned on. We use
502 this as an approximation for the destination being like a local
503 delivery, as in LMTP.
67bd1ab3
TF
504
505 I suspect this new check makes the old local delivery cutoff check
506 redundant, but I have not verified this so I left the code in place.

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

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

828TF/03 Make the exiwhat support code safe for signals. Previously Exim might
829 lock up or crash if it happened to be inside a call to libc when it
830 got a SIGUSR1 from exiwhat.
831
832 The SIGUSR1 handler appends the current process status to the process
833 log which is later printed by exiwhat. It used to use the general
834 purpose logging code to do this, but several functions it calls are
835 not safe for signals.
836
837 The new output code in the SIGUSR1 handler is specific to the process
838 log, and simple enough that it's easy to inspect for signal safety.
839 Removing some special cases also simplifies the general logging code.
840 Removing the spurious timestamps from the process log simplifies
841 exiwhat.

843TF/04 Improved ratelimit ACL condition.
844
845 The /noupdate option has been deprecated in favour of /readonly which
846 has clearer semantics. The /leaky, /strict, and /readonly update modes
847 are mutually exclusive. The update mode is no longer included in the
848 database key; it just determines when the database is updated. (This
849 means that when you upgrde Exim will forget old rate measurements.)
850
851 Exim now checks that the per_* options are used with an update mode that
852 makes sense for the current ACL. For example, when Exim is processing a
853 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
854 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
855 must specify per_mail/readonly. If you omit the update mode it defaults to
856 /leaky where that makes sense (as before) or /readonly where required.
857
858 The /noupdate option is now undocumented but still supported for
859 backwards compatibility. It is equivalent to /readonly except that in
860 ACLs where /readonly is required you may specify /leaky/noupdate or
861 /strict/noupdate which are treated the same as /readonly.
862
863 A useful new feature is the /count= option. This is a generalization
864 of the per_byte option, so that you can measure the throughput of other
865 aggregate values. For example, the per_byte option is now equivalent
866 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
867
868 The per_rcpt option has been generalized using the /count= mechanism
869 (though it's more complicated than the per_byte equivalence). When it is
870 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
871 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
872 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
873 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
874 Note that using per_rcpt with a non-readonly update mode in more than
875 one ACL will cause the recipients to be double-counted. (The per_mail
876 and per_byte options don't have this problem.)
877
878 The handling of very low rates has changed slightly. If the computed rate
879 is less than the event's count (usually one) then this event is the first
880 after a long gap. In this case the rate is set to the same as this event's
881 count, so that the first message of a spam run is counted properly.
882
883 The major new feature is a mechanism for counting the rate of unique
884 events. The new per_addr option counts the number of different
885 recipients that someone has sent messages to in the last time period. It
886 behaves like per_rcpt if all the recipient addresses are different, but
887 duplicate recipient addresses do not increase the measured rate. Like
888 the /count= option this is a general mechanism, so the per_addr option
889 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
890 example, measure the rate that a client uses different sender addresses
891 with the options per_mail/unique=$sender_address. There are further
892 details in the main documentation.

1443 were called 'true' and it seems that C99 defines that as a reserved

1462-----------------
1463
1464PH/01 Another patch from the Sieve maintainer.
1465
6a3bceb1
PH
1466PH/02 When an IPv6 address is converted to a string for single-key lookup
1467 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1468 dots are used instead of colons so that keys in lsearch files need not
1469 contain colons. This was done some time before quoting was made available
1470 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1471 (notated using the quote facility) so as to distinguish them from IPv4
1472 keys. This meant that lookups for IP addresses in host lists did not work
1473 for iplsearch lookups.
1474
1475 This has been fixed by arranging for IPv6 addresses to be expressed with
1476 colons if the lookup type is iplsearch. This is not incompatible, because
1477 previously such lookups could never work.
1478
1479 The situation is now rather anomolous, since one *can* have colons in
1480 ordinary lsearch keys. However, making the change in all cases is
1481 incompatible and would probably break a number of configurations.

MH
1486MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1487 conversion specification without a maximum field width, thereby enabling
1488 a rogue spamd server to cause a buffer overflow. While nobody in their
1489 right mind would setup Exim to query an untrusted spamd server, an
1490 attacker that gains access to a server running spamd could potentially
1491 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1496MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1497 a directory entry by the name of the lookup key. Previously, if a
1498 symlink pointed to a non-existing file or a file in a directory that
1499 Exim lacked permissions to read, a lookup for a key matching that
1500 symlink would fail. Now it is enough that a matching directory entry
1501 exists, symlink or not. (Bugzilla 503.)

1578 if a client was not listed at all, or was listed with a value other than
1579 127.0.0.2, in the X list, but was listed with 127.0.0.2 in the Y list,

1684PH/29 SMTP synchronization checks are implemented when a command is read -
1685 there is a check that no more input is waiting when there shouldn't be
1686 any. However, for some commands, a delay in an ACL can mean that it is
1687 some time before the response is written. In this time, more input might
1688 arrive, invalidly. So now there are extra checks after an ACL has run for
1689 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1690 pipelining has not been advertised.

PH
1764 the response to the final '.' that terminates a message, but only in the
1765 case where the client has not sent further data following the '.'
1766 (unfortunately, this is allowed). However, in many cases there won't be
1767 any further data because there won't be any more messages to send. A call
1768 to select() can be used: if it shows that the input is "ready", there is
1769 either input waiting, or the socket has been closed. An attempt to read
1770 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1771 would have sent an OK response which the client would never have see.

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

1812 is held in a short int, deliveries were likely to be lost. As such a
1813 large number of recipients for a single message is ridiculous
1814 (performance will be very, very poor), I have chosen to impose a limit
1815 rather than extend the field.

1822 leftover -K file (the existence of which was triggered by #402).

2b1c6e3a
PH
1840PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1841 callout verification, Exim cached a "reject" for the entire domain. This
1842 is correct for most verifications, but it is not correct for a recipient
1843 verification with use_sender or use_postmaster set, because in that case
1844 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1845 case of MAIL FROM:<> rejection from other early rejections (e.g.
1846 rejection of HELO). When verifying a recipient using a non-null MAIL
1847 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1848 Whatever the result of the callout, the value of the domain cache is
1849 left unchanged (for any other kind of callout, getting as far as trying
1850 RCPT means that the domain itself is ok).

1884PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1886 probably the interface on which it is arriving) and not to the outgoing
1887 callout (which could be using a different interface). This has been
1888 changed to use the value of the helo_data option from the smtp transport
1889 instead - this is what is used when a message is actually being sent. If
1890 there is no remote transport (possible with a router that sets up host
1891 addresses), $smtp_active_hostname is used.

7befa435 1894 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1895 (a) The code assumed that strncpy() returns a negative number on buffer
1896 overflow, which isn't the case. Replaced with Exim's string_format()
1897 function.
1898 (b) There were several signed/unsigned issues. I just did the minimum
1899 hacking in of casts. There is scope for a larger refactoring.
1900 (c) The code used strcasecmp() which is not a standard C function.
1901 Replaced with Exim's strcmpic() function.
1902 (d) The code set only $1; it now sets $auth1 as well.
1903 (e) A simple test gave the error "authentication client didn't specify
1904 service in request". It would seem that Dovecot has changed its
1905 interface. Fortunately there's a specification; I followed it and
1906 changed what the client sends and it appears to be working now.

1912 address A is aliased to B and C, where B exists and C does not. Without
1913 -v the output is "A verified" because verification stops after a
1914 successful redirection if more than one address is generated. However,
1915 with -v the child addresses are also verified. Exim was outputting "A
1916 failed to verify" and then showing the successful verification for C,
1917 with its parentage. It now outputs "B failed to verify", showing B's
1918 parentage before showing the successful verification of C.

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

1939 spool_read_header() do less string testing, by means of a preliminary
1940 switch on the second character of optional "-foo" lines. (This is
1941 overdue, caused by the large number of possibilities that now exist.
1942 Originally there were few.) While I was there, I also converted the
1943 str(n)cmp tests so they don't re-test the leading "-" and the first
1944 character, in the hope this might squeeze out yet more improvement.

1946PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1947 flag allowing group syntax was set by the header_syntax check but not
1948 turned off, possible causing trouble later; (2) The flag was not being
1949 set at all for the header_verify test, causing "group"-style headers to
1950 be rejected. I have now set it in this case, and also caused header_
1951 verify to ignore an empty address taken from a group. While doing this, I
1952 came across some other cases where the code for allowing group syntax
1953 while scanning a header line wasn't quite right (mostly, not resetting
1954 the flag correctly in the right place). These bugs could have caused
1955 trouble for malformed header lines. I hope it is now all correct.

1957PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1958 with the "reply" argument non-NULL. The code, however (which originally
1959 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1960 but it didn't always do it. This confused somebody who was copying the
1961 code for some other use. I have removed all the tests.

PH
1963PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1964 feature that was used to support insecure browsers during the U.S. crypto
1965 embargo. It requires special client support, and Exim is probably the
1966 only MTA that supported it -- and would never use it because real RSA is
1967 always available. This code has been removed, because it had the bad
1968 effect of slowing Exim down by computing (never used) parameters for the
1969 RSA_EXPORT functionality.

1971PH/21 On the advice of Timo Sirainen, added a check to the dovecot

1974 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1975 if the connection is using TLS or if the remote IP is the same as the
1976 local IP, and the "valid-client-cert option" if a client certificate has
1977 been verified.

2008
2009PH/30 Exim was sometimes attempting to deliver messages that had suffered
2010 address errors (4xx response to RCPT) over the same connection as other
2011 messages routed to the same hosts. Such deliveries are always "forced",
2012 so retry times are not inspected. This resulted in far too many retries
2013 for the affected addresses. The effect occurred only when there were more
2014 hosts than the hosts_max_try setting in the smtp transport when it had
2015 the 4xx errors. Those hosts that it had tried were not added to the list
2016 of hosts for which the message was waiting, so if all were tried, there
2017 was no problem. Two fixes have been applied:
2018
2019 (i) If there are any address or message errors in an SMTP delivery, none
2020 of the hosts (tried or untried) are now added to the list of hosts
2021 for which the message is waiting, so the message should not be a
2022 candidate for sending over the same connection that was used for a
2023 successful delivery of some other message. This seems entirely
2024 reasonable: after all the message is NOT "waiting for some host".
2025 This is so "obvious" that I'm not sure why it wasn't done
2026 previously. Hope I haven't missed anything, but it can't do any
2027 harm, as the worst effect is to miss an optimization.
2028
2029 (ii) If, despite (i), such a delivery is accidentally attempted, the
2030 routing retry time is respected, so at least it doesn't keep
2031 hammering the server.

2046PH/35 The error "getsockname() failed: connection reset by peer" was being
2047 written to the panic log as well as the main log, but it isn't really
2048 panic-worthy as it just means the connection died rather early on. I have
2049 removed the panic log writing for the ECONNRESET error when getsockname()
2050 fails.
2051
48c7f9e2
PH
2052PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
2053 runs only) independently of the message's sender address. This meant
2054 that, if the 4xx error was in fact related to the sender, a different
2055 message to the same recipient with a different sender could confuse
2056 things. In particualar, this can happen when sending to a greylisting
2057 server, but other circumstances could also provoke similar problems.
2058 I have changed the default so that the retry time for these errors is now
2059 based a combination of the sender and recipient addresses. This change
2060 can be overridden by setting address_retry_include_sender=false in the
2061 smtp transport.

2334 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2335 554 error is used if errno is still zero or contains ENOENT (which occurs

2359PH/09 If maildir_quota_directory_regex was set to exclude (say) the .Trash
2360 folder from quota calculations, a direct delivery into this folder messed
2361 up the contents of the maildirsize file. This was because the regex was
2362 used only to exclude .Trash (or whatever) when the size of the mailbox
2363 was calculated. There was no check that a delivery was happening into an

2373PH/01 The code for finding all the local interface addresses on a FreeBSD
2374 system running IPv6 was broken. This may well have applied to all BSD
2375 systems, as well as to others that have similar system calls. The broken
2376 code found IPv4 interfaces correctly, but gave incorrect values for the
2377 IPv6 interfaces. In particular, ::1 was not found. The effect in Exim was
2378 that it would not match correctly against @[] and not recognize the IPv6
2379 addresses as local.

2457 additional section of a DNS packet that returns MX or SRV records.
2458 Instead, it always explicitly searches for A/AAAA records. This avoids
2459 major problems that occur when a DNS server includes only records of one
2460 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2461 fixed another bug: if SRV records were looked up and the corresponding
2462 address records were *not* found in the additional section, the port
2463 values from the SRV records were lost.

PH
2473PH/19 When calculating a retry time, Exim used to measure the "time since
2474 failure" by looking at the "first failed" field in the retry record. Now
2475 it does not use this if it is later than than the arrival time of the
2476 message. Instead it uses the arrival time. This makes for better
2477 behaviour in cases where some deliveries succeed, thus re-setting the
2478 "first failed" field. An example is a quota failure for a huge message
2479 when small messages continue to be delivered. Without this change, the
2480 "time since failure" will always be short, possible causing more frequent
2481 delivery attempts for the huge message than are intended.

PH
2578PH/42 The content-scanning code uses fopen() to create files in which to put
2579 message data. Previously it was not paying any attention to the mode of
2580 the files. Exim runs with umask(0) because the rest of the code creates
2581 files with open(), and sets the required mode explicitly. Thus, these
2582 files were ending up world-writeable. This was not a big issue, because,
2583 being within the spool directory, they were not world-accessible. I have
2584 created a function called modefopen, which takes an additional mode
2585 argument. It sets umask(777), creates the file, chmods it to the required
2586 mode, then resets the umask. All the relevant calls to fopen() in the
2587 content scanning code have been changed to use this function.

2624
2625 (i) Exim was not creating retry information for temporary errors given

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

2709 function verify_get_ident() calls ip_connect() to connect a socket, but
2710 if the "connect()" function timed out, ip_connect() used to close the
2711 socket. However, verify_get_ident() also closes the socket later, and in
2712 between Exim writes to the log, which may get opened at this point. When
2713 the socket was closed in ip_connect(), the log could get the same file
2714 descriptor number as the socket. This naturally causes chaos. The fix is
2715 not to close the socket in ip_connect(); the socket should be closed by
2716 the function that creates it. There was only one place in the code where
2717 this was missing, in the iplookup router, which I don't think anybody now

2737PH/02 Several tidies to the handling of ${prvs and ${prvscheck:
2738
2739 (1) Generate an error if the third argument for the ${prvs expansion is
2740 not a single digit.
2741
2742 (2) Treat a missing third argument of ${prvscheck as if it were an empty
2743 string.
2744
2745 (3) Reset the variables that are obtained from the first argument of
2746 ${prvscheck and used in the second argument before leaving the code,
2747 because their memory is reclaimed, so using them afterwards may do
2748 silly things.
2749
2750 (4) Tidy up the code for expanding the arguments of ${prvscheck one by
2751 one (it's much easier than Tom thought :-).
2752
2753 (5) Because of (4), we can now allow for the use of $prvscheck_result
2754 inside the third argument.

2774PH/06 When a client host used a correct literal IP address in a HELO or EHLO
2775 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2776 not being looked up in the rDNS to get a host name, Exim was showing the
2777 IP address twice in Received: lines, even though the IP addresses were
2778 identical. For example:
2779
2780 Received: from [1.2.3.4] (helo=[1.2.3.4])
2781
2782 However, if the real host name was known, it was omitting the HELO data
2783 if it matched the actual IP address. This has been tidied up so that it
2784 doesn't show the same IP address twice.

2812
2813 Auto-submitted: auto-generated
2814
2815 in the messages that it generates (bounce messages and others, such as
2816 warnings). In the case of bounce messages for non-SMTP mesages, there was
2817 also a typo: it was using "Auto_submitted" (underscore instead of
2818 hyphen). Since every message generated by Exim is necessarily in response
2819 to another message, thes have all been changed to:
2820
2821 Auto-Submitted: auto-replied
2822
2823 in accordance with these statements in the RFC:
2824
2825 The auto-replied keyword:
2826
2827 - SHOULD be used on messages sent in direct response to another
2828 message by an automatic process,
2829
2830 - MUST NOT be used on manually-generated messages,

2833 Disposition Notifications (MDNs),

2873PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2874 canonical form (as documented). However, after a host name lookup from
2875 the IP address, check_host() was doing a simple string comparison with
2876 addresses acquired from the DNS when checking that the found name did
2877 have the original IP as one of its addresses. Since any found IPv6
2878 addresses are likely to be in abbreviated form, the comparison could
2879 fail. Luckily, there already exists a function for doing the comparison
2880 by converting both addresses to binary, so now that is used instead of
2881 the text comparison.

3145PH/01 When a transport filter timed out in a pipe delivery, and the pipe
3146 command itself ended in error, the underlying message about the transport
3147 filter timeout was being overwritten with the pipe command error. Now the
3148 underlying error message should be appended to the second error message.

3155PH/03 The warning log line about a condition test deferring for a "warn" verb
3156 was being output only once per connection, rather than after each

3158 "warn" verbs). This seems wrong, so I have changed it.

3160TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
3161 it should not have, which might have caused a crash in the right

3178PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
3179 with the definition in sysexits.h (which is #included earlier).
3180 Fortunately, Exim does not actually use EX_OK. The code used to try to
3181 preserve the sysexits.h value, by assumimg that macro definitions were
3182 scanned for macro replacements. I have been disabused of this notion,
3183 so now the code just undefines EX_OK before #including unistd.h.

PH
3185PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
3186 in the smtp transport. When a block could not be written in a single
3187 write() function, the timeout was being re-applied to each part-write.
3188 This seems wrong - if the receiver was accepting one byte at a time it
3189 would take for ever. The timeout is now adjusted when this happens. It
3190 doesn't have to be particularly precise.

3256PH/15 The code I had for printing potentially long long variables in PH/11

3259 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T

3263PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3264 the configuration file to be ":syslog", then the script "guesses" where
3265 the logs files are, rather than using the compiled in default. In our
3266 case the guess is not the same as the compiled default, so the script
3267 suddenly stopped working when I started to use syslog. The patch checks
3268 to see if log_file_path is "". If so, it attempts to read it from exim
3269 with no configuration file to get the compiled in version, before it
3270 falls back to the previous guessing code."

3320 picked up on a user's system that detects such things. There doesn't seem
3321 to be a gcc warning option for this - only an attribute that has to be
3322 put on the function's prototype. It seems that in Fedora Core 4 they have
3323 set this on a number of new functions. No doubt there will be more in due
3324 course.

PH
3326PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3327 specify a transport. However, if an address that was verified by such a
3328 router was the subject of a callout, Exim crashed because it tried to
3329 read the rcpt_include_affixes from the non-existent transport. Now it
3330 just assumes that the setting of that option is false. This bug was
