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18 EXPERIMENTAL_CERTNAMES is withdrawn.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.

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
f926e272

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

58Exim version 4.85
59-----------------
60TL/01 When running the test suite, the README says that variables such as
61 no_msglog_check are global and can be placed anywhere in a specific
62 test's script, however it was observed that placement needed to be near
63 the beginning for it to behave that way. Changed the runtest perl
64 script to read through the entire script once to detect and set these
65 variables, reset to the beginning of the script, and then run through
66 the script parsing/test process like normal.
67
ac20058f
TL
68TL/02 The BSD's have an arc4random API. One of the functions to induce
69 adding randomness was arc4random_stir(), but it has been removed in
70 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
71 function when detected.
72
a9b8ec8b
JH
73JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
74 cause callback expansion.
75
6286d7c4
TL
76TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
77 syntax errors in an expansion can be treated as a string instead of
78 logging or causing an error, due to the internal use of bool_lax
79 instead of bool when processing it.
80
0f06b4f2 81JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
82 server certificates when making smtp deliveries.
83
be36e572
JH
84JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.
85

bd21a787
WB
93JH/05 Fix results-pipe from transport process. Several recipients, combined
94 with certificate use, exposed issues where response data items split
95 over buffer boundaries were not parsed properly. This eventually
96 resulted in duplicates being sent. This issue only became common enough
97 to notice due to the introduction of conection certificate information,
98 the item size being so much larger. Found and fixed by Wolfgang Breyha.
99
8bc732e8
JH
100JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
101 size buffer was used, resulting in syntax errors when an expansion
102 exceeded it.
103
a7fec7a7
JH
104JH/07 Add support for directories of certificates when compiled with a GnuTLS
105 version 3.3.6 or later.
106
774ef2d7
JH
107JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
108 is EXPERIMENTAL_EVENT, the main-configuration and transport options
109 both become "event_action", the variables become $event_name, $event_data
aec45841 110 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
111 routers, transports and related events. The tls:cert event is now also
112 raised for inbound connections, if the main configuration event_action
113 option is defined.
774ef2d7 114
eca4debb
TL
115TL/06 In test suite, disable OCSP for old versions of openssl which contained
116 early OCSP support, but no stapling (appears to be less than 1.0.0).
117
8d692470
JH
118JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
119 server certificate names available under the smtp transport option
120 "tls_verify_cert_hostname" now do not permit multi-component wildcard
121 matches.
122
e9477a08
JH
123JH/10 Time-related extraction expansions from certificates now use the main
124 option "timezone" setting for output formatting, and are consistent
125 between OpenSSL and GnuTLS compilations. Bug 1541.
126
ad4c5ff9
JH
127JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
128 encoded parameter in the incoming message. Bug 1558.

JH
129
130JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
131 include certificate info, eximon was claiming there were spoolfile
132 syntax errors.

140 are problematic for Debian distribution, omit them from the release
141 tarball.

167Exim version 4.83
168-----------------
169
170TF/01 Correctly close the server side of TLS when forking for delivery.
171
172 When a message was received over SMTP with TLS, Exim failed to clear up
173 the incoming connection properly after forking off the child process to
174 deliver the message. In some situations the subsequent outgoing
175 delivery connection happened to have the same fd number as the incoming
176 connection previously had. Exim would try to use TLS and fail, logging
177 a "Bad file descriptor" error.
178
7245734e
TF
179TF/02 Portability fix for building lookup modules on Solaris when the xpg4
180 utilities have not been installed.
181
fd5dad68
JH
182JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
183 temporary space as the ACL may create new global variables.

TL
185TL/01 LDAP support uses per connection or global context settings, depending
186 upon the detected version of the libraries at build time.
187
a3c86431
TL
188TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
189 to extract and use the src ip:port in logging and expansions as if it
8ded8589
TL
190 were a direct connection from the outside internet. PPv2 support was
191 updated based on HAProxy spec change in May 2014.

206
8ddef691 207TL/05 Rename SPF condition results err_perm and err_temp to standardized

TL
208 results permerror and temperror. Previous values are deprecated but
209 still accepted. In a future release, err_perm and err_temp will be
210 completely removed, which will be a backward incompatibility if the
211 ACL tests for either of these two old results. Patch contributed by
8ddef691 212 user bes-internal on the mailing list.

236JH/12 Expand items in router/transport headers_add or headers_remove lists
237 individually rather than the list as a whole. Bug 1452.
238
239 Required for reasonable handling of multiple headers_ options when
240 they may be empty; requires that headers_remove items with embedded

423TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
424
425 When a queue runner is handling a message, Exim first routes the
426 recipient addresses, during which it prunes them based on the retry
427 hints database. After that it attempts to deliver the message to
428 any remaining recipients. It then updates the hints database using
429 the retry rules.
430
431 So if a recipient address works intermittently, it can get repeatedly
432 deferred at routing time. The retry hints record remains fresh so the
433 address never reaches the final cutoff time.
434
435 This is a fairly common occurrence when a user is bumping up against
436 their storage quota. Exim had some logic in its local delivery code
437 to deal with this. However it did not apply to per-recipient defers
438 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
439
1ddeb334
TF
440 This change adds a proper retry rule check during routing so that the
441 final cutoff time is checked against the message's age. We only do
442 this check if there is an address retry record and there is not a
443 domain retry record; this implies that previous attempts to handle
444 the address had the retry_use_local_parts option turned on. We use
445 this as an approximation for the destination being like a local
446 delivery, as in LMTP.
67bd1ab3
TF
447
448 I suspect this new check makes the old local delivery cutoff check
449 redundant, but I have not verified this so I left the code in place.

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

484 Server implementation by Todd Lyons, client by JH.
485 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
486 config variable "prdr_enable" controls whether the server
487 advertises the facility. If the client requests PRDR a new
488 acl_data_smtp_prdr ACL is called once for each recipient, after
489 the body content is received and before the acl_smtp_data ACL.
490 The client is controlled by bolth of: a hosts_try_prdr option
491 on the smtp transport, and the server advertisement.
492 Default client logging of deliveries and rejections involving
493 PRDR are flagged with the string "PRDR".

771TF/03 Make the exiwhat support code safe for signals. Previously Exim might
772 lock up or crash if it happened to be inside a call to libc when it
773 got a SIGUSR1 from exiwhat.
774
775 The SIGUSR1 handler appends the current process status to the process
776 log which is later printed by exiwhat. It used to use the general
777 purpose logging code to do this, but several functions it calls are
778 not safe for signals.
779
780 The new output code in the SIGUSR1 handler is specific to the process
781 log, and simple enough that it's easy to inspect for signal safety.
782 Removing some special cases also simplifies the general logging code.
783 Removing the spurious timestamps from the process log simplifies
784 exiwhat.
785
c99ce5c9
TF
786TF/04 Improved ratelimit ACL condition.
787
788 The /noupdate option has been deprecated in favour of /readonly which
789 has clearer semantics. The /leaky, /strict, and /readonly update modes
790 are mutually exclusive. The update mode is no longer included in the
791 database key; it just determines when the database is updated. (This
792 means that when you upgrde Exim will forget old rate measurements.)
793
794 Exim now checks that the per_* options are used with an update mode that
795 makes sense for the current ACL. For example, when Exim is processing a
796 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
797 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
798 must specify per_mail/readonly. If you omit the update mode it defaults to
799 /leaky where that makes sense (as before) or /readonly where required.
800
801 The /noupdate option is now undocumented but still supported for
802 backwards compatibility. It is equivalent to /readonly except that in
803 ACLs where /readonly is required you may specify /leaky/noupdate or
804 /strict/noupdate which are treated the same as /readonly.
805
806 A useful new feature is the /count= option. This is a generalization
807 of the per_byte option, so that you can measure the throughput of other
808 aggregate values. For example, the per_byte option is now equivalent
809 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
810
811 The per_rcpt option has been generalized using the /count= mechanism
812 (though it's more complicated than the per_byte equivalence). When it is
813 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
814 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
815 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
816 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
817 Note that using per_rcpt with a non-readonly update mode in more than
818 one ACL will cause the recipients to be double-counted. (The per_mail
819 and per_byte options don't have this problem.)
820
821 The handling of very low rates has changed slightly. If the computed rate
822 is less than the event's count (usually one) then this event is the first
823 after a long gap. In this case the rate is set to the same as this event's
824 count, so that the first message of a spam run is counted properly.
825
826 The major new feature is a mechanism for counting the rate of unique
827 events. The new per_addr option counts the number of different
828 recipients that someone has sent messages to in the last time period. It
829 behaves like per_rcpt if all the recipient addresses are different, but
830 duplicate recipient addresses do not increase the measured rate. Like
831 the /count= option this is a general mechanism, so the per_addr option
832 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
833 example, measure the rate that a client uses different sender addresses
834 with the options per_mail/unique=$sender_address. There are further
835 details in the main documentation.

1386 were called 'true' and it seems that C99 defines that as a reserved

1388 not include C99-style headers which use bools without triggering

1408
6a3bceb1
PH
1409PH/02 When an IPv6 address is converted to a string for single-key lookup
1410 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1411 dots are used instead of colons so that keys in lsearch files need not
1412 contain colons. This was done some time before quoting was made available
1413 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1414 (notated using the quote facility) so as to distinguish them from IPv4
1415 keys. This meant that lookups for IP addresses in host lists did not work
1416 for iplsearch lookups.
1417
1418 This has been fixed by arranging for IPv6 addresses to be expressed with
1419 colons if the lookup type is iplsearch. This is not incompatible, because
1420 previously such lookups could never work.
1421
1422 The situation is now rather anomolous, since one *can* have colons in
1423 ordinary lsearch keys. However, making the change in all cases is
1424 incompatible and would probably break a number of configurations.

1429MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1430 conversion specification without a maximum field width, thereby enabling
1431 a rogue spamd server to cause a buffer overflow. While nobody in their
1432 right mind would setup Exim to query an untrusted spamd server, an
1433 attacker that gains access to a server running spamd could potentially
1434 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1439MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1440 a directory entry by the name of the lookup key. Previously, if a
1441 symlink pointed to a non-existing file or a file in a directory that
1442 Exim lacked permissions to read, a lookup for a key matching that
1443 symlink would fail. Now it is enough that a matching directory entry
1444 exists, symlink or not. (Bugzilla 503.)

1627PH/29 SMTP synchronization checks are implemented when a command is read -
1628 there is a check that no more input is waiting when there shouldn't be
1629 any. However, for some commands, a delay in an ACL can mean that it is
1630 some time before the response is written. In this time, more input might
1631 arrive, invalidly. So now there are extra checks after an ACL has run for
1632 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1633 pipelining has not been advertised.

1689 with PIPELINING or a stupid MUA), the error message that was given to the

PH
1707 the response to the final '.' that terminates a message, but only in the
1708 case where the client has not sent further data following the '.'
1709 (unfortunately, this is allowed). However, in many cases there won't be
1710 any further data because there won't be any more messages to send. A call
1711 to select() can be used: if it shows that the input is "ready", there is
1712 either input waiting, or the socket has been closed. An attempt to read
1713 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1714 would have sent an OK response which the client would never have see.

1724
1725PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1726 fixed by 4.65/MH/01 (is this a record?) are fixed:
1727
1728 (i) An empty string was always treated as zero by the numeric comparison
1729 operators. This behaviour has been restored.
1730
1731 (ii) It is documented that the numeric comparison operators always treat
1732 their arguments as decimal numbers. This was broken in that numbers
1733 starting with 0 were being interpreted as octal.
1734
1735 While fixing these problems I realized that there was another issue that
1736 hadn't been noticed. Values of message_size_limit (both the global option
1737 and the transport option) were treated as octal if they started with 0.
1738 The documentation was vague. These values are now always treated as
1739 decimal, and I will make that clear in the documentation.

1753PH/01 If a system filter or a router generates more than SHRT_MAX (32767)
1754 child addresses, Exim now panics and dies. Previously, because the count
1755 is held in a short int, deliveries were likely to be lost. As such a
1756 large number of recipients for a single message is ridiculous
1757 (performance will be very, very poor), I have chosen to impose a limit
1758 rather than extend the field.

1774TK/03 Introduced HAVE_LINUX_SENDFILE to os.h-Linux. Currently only used

2b1c6e3a
PH
1783PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1784 callout verification, Exim cached a "reject" for the entire domain. This
1785 is correct for most verifications, but it is not correct for a recipient
1786 verification with use_sender or use_postmaster set, because in that case
1787 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1788 case of MAIL FROM:<> rejection from other early rejections (e.g.
1789 rejection of HELO). When verifying a recipient using a non-null MAIL
1790 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1791 Whatever the result of the callout, the value of the domain cache is
1792 left unchanged (for any other kind of callout, getting as far as trying
1793 RCPT means that the domain itself is ok).

1827PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1829 probably the interface on which it is arriving) and not to the outgoing
1830 callout (which could be using a different interface). This has been
1831 changed to use the value of the helo_data option from the smtp transport
1832 instead - this is what is used when a message is actually being sent. If
1833 there is no remote transport (possible with a router that sets up host
1834 addresses), $smtp_active_hostname is used.

7befa435 1837 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1838 (a) The code assumed that strncpy() returns a negative number on buffer
1839 overflow, which isn't the case. Replaced with Exim's string_format()
1840 function.
1841 (b) There were several signed/unsigned issues. I just did the minimum
1842 hacking in of casts. There is scope for a larger refactoring.
1843 (c) The code used strcasecmp() which is not a standard C function.
1844 Replaced with Exim's strcmpic() function.
1845 (d) The code set only $1; it now sets $auth1 as well.
1846 (e) A simple test gave the error "authentication client didn't specify
1847 service in request". It would seem that Dovecot has changed its
1848 interface. Fortunately there's a specification; I followed it and
1849 changed what the client sends and it appears to be working now.

1854PH/14 Corrected misleading output from -bv when -v was also used. Suppose the
1855 address A is aliased to B and C, where B exists and C does not. Without
1856 -v the output is "A verified" because verification stops after a
1857 successful redirection if more than one address is generated. However,
1858 with -v the child addresses are also verified. Exim was outputting "A
1859 failed to verify" and then showing the successful verification for C,
1860 with its parentage. It now outputs "B failed to verify", showing B's
1861 parentage before showing the successful verification of C.

1864 look up a TXT record in a specific list after matching in a combined

1866
322050c2
PH
1867PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1868 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1869 they consult the DNS. I had assumed they would set it the way they
1870 wanted; and indeed my experiments on Linux seem to show that in some
1871 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1872 To be on the safe side, however, I have now made the interface to
1873 host_find_byname() similar to host_find_bydns(), with an argument
1874 containing the DNS resolver options. The host_find_byname() function now
1875 sets these options at its start, just as host_find_bydns() does. The smtp
1876 transport options dns_qualify_single and dns_search_parents are passed to
1877 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1878 of host_find_byname() use the default settings of RES_DEFNAMES
1879 (qualify_single) but not RES_DNSRCH (search_parents).

1881PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1882 spool_read_header() do less string testing, by means of a preliminary
1883 switch on the second character of optional "-foo" lines. (This is
1884 overdue, caused by the large number of possibilities that now exist.
1885 Originally there were few.) While I was there, I also converted the
1886 str(n)cmp tests so they don't re-test the leading "-" and the first
1887 character, in the hope this might squeeze out yet more improvement.

PH
1889PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1890 flag allowing group syntax was set by the header_syntax check but not
1891 turned off, possible causing trouble later; (2) The flag was not being
1892 set at all for the header_verify test, causing "group"-style headers to
1893 be rejected. I have now set it in this case, and also caused header_
1894 verify to ignore an empty address taken from a group. While doing this, I
1895 came across some other cases where the code for allowing group syntax
1896 while scanning a header line wasn't quite right (mostly, not resetting
1897 the flag correctly in the right place). These bugs could have caused
1898 trouble for malformed header lines. I hope it is now all correct.

PH
1900PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1901 with the "reply" argument non-NULL. The code, however (which originally
1902 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1903 but it didn't always do it. This confused somebody who was copying the
1904 code for some other use. I have removed all the tests.

PH
1906PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1907 feature that was used to support insecure browsers during the U.S. crypto
1908 embargo. It requires special client support, and Exim is probably the
1909 only MTA that supported it -- and would never use it because real RSA is
1910 always available. This code has been removed, because it had the bad
1911 effect of slowing Exim down by computing (never used) parameters for the
1912 RSA_EXPORT functionality.

1917 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1918 if the connection is using TLS or if the remote IP is the same as the
1919 local IP, and the "valid-client-cert option" if a client certificate has
1920 been verified.

1952PH/30 Exim was sometimes attempting to deliver messages that had suffered
1953 address errors (4xx response to RCPT) over the same connection as other
1954 messages routed to the same hosts. Such deliveries are always "forced",
1955 so retry times are not inspected. This resulted in far too many retries
1956 for the affected addresses. The effect occurred only when there were more
1957 hosts than the hosts_max_try setting in the smtp transport when it had
1958 the 4xx errors. Those hosts that it had tried were not added to the list
1959 of hosts for which the message was waiting, so if all were tried, there
1960 was no problem. Two fixes have been applied:

1962 (i) If there are any address or message errors in an SMTP delivery, none
1963 of the hosts (tried or untried) are now added to the list of hosts
1964 for which the message is waiting, so the message should not be a
1965 candidate for sending over the same connection that was used for a
1966 successful delivery of some other message. This seems entirely
1967 reasonable: after all the message is NOT "waiting for some host".
1968 This is so "obvious" that I'm not sure why it wasn't done
1969 previously. Hope I haven't missed anything, but it can't do any
1970 harm, as the worst effect is to miss an optimization.
1971
1972 (ii) If, despite (i), such a delivery is accidentally attempted, the
1973 routing retry time is respected, so at least it doesn't keep
1974 hammering the server.

1989PH/35 The error "getsockname() failed: connection reset by peer" was being
1990 written to the panic log as well as the main log, but it isn't really
1991 panic-worthy as it just means the connection died rather early on. I have
1992 removed the panic log writing for the ECONNRESET error when getsockname()
1993 fails.

PH
1995PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1996 runs only) independently of the message's sender address. This meant
1997 that, if the 4xx error was in fact related to the sender, a different
1998 message to the same recipient with a different sender could confuse
1999 things. In particualar, this can happen when sending to a greylisting
2000 server, but other circumstances could also provoke similar problems.
2001 I have changed the default so that the retry time for these errors is now
2002 based a combination of the sender and recipient addresses. This change
2003 can be overridden by setting address_retry_include_sender=false in the
2004 smtp transport.

2276 kind of temporary error. A kludge has been added to help with this.
2277 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2278 554 error is used if errno is still zero or contains ENOENT (which occurs

2363 syntactically invalid From: or Reply-to: line, and a filter used this to
2364 generate an autoreply, and therefore failed to obtain an address for the
2365 autoreply, Exim could try to deliver to a non-existent relative file
2366 name, causing unrelated and misleading errors. What now happens is that
2367 it logs this as a hard delivery error, but does not attempt to create a
2368 bounce message.

2382PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

2385 non-existent - all you got was a failure to exec. I have made two
2386 changes:
2387
2388 (a) Failures to set uid/gid, the current directory, or a process leader
2389 in a subprocess such as that created by queryprogram now generate
2390 suitable debugging ouput when -d is set.
2391
2392 (b) The queryprogram router detects when it is not running as root,
2393 outputs suitable debugging information if -d is set, and then runs
2394 the subprocess without attempting to change uid/gid.

PH
2399PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2400 additional section of a DNS packet that returns MX or SRV records.
2401 Instead, it always explicitly searches for A/AAAA records. This avoids
2402 major problems that occur when a DNS server includes only records of one
2403 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2404 fixed another bug: if SRV records were looked up and the corresponding
2405 address records were *not* found in the additional section, the port
2406 values from the SRV records were lost.

2408PH/17 If a delivery to a pipe, file, or autoreply was deferred, Exim was not

PH
2412PH/18 If quota_warn_message contains a From: header, Exim now refrains from

2414 errors_reply_to option, if set, is not used.
2415
727071f8
PH
2416PH/19 When calculating a retry time, Exim used to measure the "time since
2417 failure" by looking at the "first failed" field in the retry record. Now
2418 it does not use this if it is later than than the arrival time of the
2419 message. Instead it uses the arrival time. This makes for better
2420 behaviour in cases where some deliveries succeed, thus re-setting the
2421 "first failed" field. An example is a quota failure for a huge message
2422 when small messages continue to be delivered. Without this change, the
2423 "time since failure" will always be short, possible causing more frequent
2424 delivery attempts for the huge message than are intended.

PH
2521PH/42 The content-scanning code uses fopen() to create files in which to put
2522 message data. Previously it was not paying any attention to the mode of
2523 the files. Exim runs with umask(0) because the rest of the code creates
2524 files with open(), and sets the required mode explicitly. Thus, these
2525 files were ending up world-writeable. This was not a big issue, because,
2526 being within the spool directory, they were not world-accessible. I have
2527 created a function called modefopen, which takes an additional mode
2528 argument. It sets umask(777), creates the file, chmods it to the required
2529 mode, then resets the umask. All the relevant calls to fopen() in the
2530 content scanning code have been changed to use this function.

2541 received. Setting client_ignore_invalid_base64 true ignores these errors.
2542 The decoded challenge strings are now placed in $auth1, $auth2, etc. as
2543 they are received. Thus, the responses can be made to depend on the
2544 challenges. If an invalid string is ignored, an empty string is placed in

2565PH/52 Two bugs concerned with error handling when the smtp transport is
2566 used in LMTP mode:
2567
2568 (i) Exim was not creating retry information for temporary errors given
2569 for individual recipients after the DATA command when the smtp transport
2570 was used in LMTP mode. This meant that they could be retried too
2571 frequently, and not timed out correctly.
2572
2573 (ii) Exim was setting the flag that allows error details to be returned
2574 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2575 recipients that were returned after the DATA command.
2576
2577PH/53 This is related to PH/52, but is more general: for any failing address,
2578 when detailed error information was permitted to be returned to the
2579 sender, but the error was temporary, then after the final timeout, only
2580 "retry timeout exceeded" was returned. Now it returns the full error as
2581 well as "retry timeout exceeded".

2651PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2652 function verify_get_ident() calls ip_connect() to connect a socket, but
2653 if the "connect()" function timed out, ip_connect() used to close the
2654 socket. However, verify_get_ident() also closes the socket later, and in
2655 between Exim writes to the log, which may get opened at this point. When
2656 the socket was closed in ip_connect(), the log could get the same file
2657 descriptor number as the socket. This naturally causes chaos. The fix is
2658 not to close the socket in ip_connect(); the socket should be closed by
2659 the function that creates it. There was only one place in the code where
2660 this was missing, in the iplookup router, which I don't think anybody now
2661 uses, but I've fixed it anyway.

2687
2688 (3) Reset the variables that are obtained from the first argument of
2689 ${prvscheck and used in the second argument before leaving the code,
2690 because their memory is reclaimed, so using them afterwards may do
2691 silly things.

2718 command, (for example, EHLO [1.2.3.4]) and the client's IP address was
2719 not being looked up in the rDNS to get a host name, Exim was showing the
2720 IP address twice in Received: lines, even though the IP addresses were
2721 identical. For example:
2722
2723 Received: from [1.2.3.4] (helo=[1.2.3.4])
2724
2725 However, if the real host name was known, it was omitting the HELO data

2727 doesn't show the same IP address twice.

2753PH/10 Exim was violating RFC 3834 ("Recommendations for Automatic Responses to
2754 Electronic Mail") by including:
2755
2756 Auto-submitted: auto-generated
2757
2758 in the messages that it generates (bounce messages and others, such as
2759 warnings). In the case of bounce messages for non-SMTP mesages, there was
2760 also a typo: it was using "Auto_submitted" (underscore instead of
2761 hyphen). Since every message generated by Exim is necessarily in response
2762 to another message, thes have all been changed to:
2763
2764 Auto-Submitted: auto-replied
2765
2766 in accordance with these statements in the RFC:
2767
2768 The auto-replied keyword:
2769
2770 - SHOULD be used on messages sent in direct response to another
2771 message by an automatic process,
2772
2773 - MUST NOT be used on manually-generated messages,
2774
2775 - MAY be used on Delivery Status Notifications (DSNs) and Message
2776 Disposition Notifications (MDNs),
2777
2778 - MUST NOT be used on messages generated by automatic or periodic
2779 processes, except for messages which are automatic responses to
2780 other messages.

2816PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2817 canonical form (as documented). However, after a host name lookup from
2818 the IP address, check_host() was doing a simple string comparison with
2819 addresses acquired from the DNS when checking that the found name did
2820 have the original IP as one of its addresses. Since any found IPv6
2821 addresses are likely to be in abbreviated form, the comparison could
2822 fail. Luckily, there already exists a function for doing the comparison
2823 by converting both addresses to binary, so now that is used instead of
2824 the text comparison.

96776534
PH
2826PH/20 There was another similar case to PH/19, when a complete host name was

3124 preserve the sysexits.h value, by assumimg that macro definitions were

3156TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller.
3157
3158TK/06 MBOX spool code: Add real "From " MBOX separator line
3159 so the .eml file is really in mbox format (even though
3160 most programs do not really care). Patch from Alex Miller.
3161
3162TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
3163 The latter is generated from $received_to and is only set if the
3164 message has one envelope recipient. SA can use these headers,
3165 obviously out-of-the-box. Patch from Alex Miller.

3167PH/08 The ${def test on a variable was returning false if the variable's
3168 value was "0", contrary to what the specification has always said!
3169 The result should be true unless the variable is empty.
3170
3171PH/09 The syntax error of a character other than { following "${if
3172 def:variable_name" (after optional whitespace) was not being diagnosed.
3173 An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
3174 accidental colon was present, for example, could give incorrect results.

PH
3176PH/10 Tidied the code in a number of places where the st_size field of a stat()
3177 result is used (not including appendfile, where other changes are about
3178 to be made).
3179
3180PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
3181 This involved changing a lot of size variables from int to off_t. It
3182 should work with maildirs and everything.

PH
3199PH/15 The code I had for printing potentially long long variables in PH/11
3200 above was not the best (it lost precision). The length of off_t variables
3201 is now inspected at build time, and an appropriate printing format (%ld
c6c2dc1d
PH
3202 or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
3203 to be "long long int" or "long int". This is needed for the internal
3204 formatting function string_vformat().

PH
3206PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3207 the configuration file to be ":syslog", then the script "guesses" where
3208 the logs files are, rather than using the compiled in default. In our
3209 case the guess is not the same as the compiled default, so the script
3210 suddenly stopped working when I started to use syslog. The patch checks
3211 to see if log_file_path is "". If so, it attempts to read it from exim
3212 with no configuration file to get the compiled in version, before it
3213 falls back to the previous guessing code."

TK
3215TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with

PH
3222PH/18 If the "use_postmaster" option was set for a recipient callout together
3223 with the "random" option, the postmaster address was used as the MAIL
3224 FROM address for the random test, but not for the subsequent recipient
3225 test. It is now used for both.

PH
3227PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
3228 patch removes a few documentation additions to RFC 3028, because the
3229 latest draft now contains them. It adds the new en;ascii-case comparator
3230 and a new error check for 8bit text in MIME parts. Comparator and
3231 require names are now matched exactly. I enabled the subaddress
3232 extension, but it is not well tested yet (read: it works for me)."

PH
3234PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
3235 rework some of the code of TK/09 above to avoid the hardwired use of
3236 "%lld" and "long long". Replaced the call to snprintf() with a call to
3237 string_vformat().

PH
3239PH/21 Added some other messages to those in 4.51/PH/42, namely "All relevant MX
3240 records point to non-existent hosts", "retry timeout exceeded", and
3241 "retry time not reached for any host after a long failure period".

3243PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
3244 experimental DomainKeys support:
3245
3246 (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
3247 (2) On an error such as an illegally used "control", the wrong name for
3248 the control was given.
3249
3250 These problems did NOT occur unless DomainKeys support was compiled.

PH
3256PH/25 Put debug statements on either side of calls to EXIM_DBOPEN() for hints
3257 databases so that it will be absolutely obvious if a crash occurs in the
3258 DB library. This is a regular occurrence (often caused by mis-matched
3259 db.h files).
3260
ff790e47 3261PH/26 Insert a lot of missing (void) casts for functions such as chown(),
f1e894f3
PH
3262 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3263 picked up on a user's system that detects such things. There doesn't seem
3264 to be a gcc warning option for this - only an attribute that has to be
3265 put on the function's prototype. It seems that in Fedora Core 4 they have
3266 set this on a number of new functions. No doubt there will be more in due
3267 course.

PH
3269PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3270 specify a transport. However, if an address that was verified by such a
3271 router was the subject of a callout, Exim crashed because it tried to
3272 read the rcpt_include_affixes from the non-existent transport. Now it
3273 just assumes that the setting of that option is false. This bug was
3274 introduced by 4.51/PH/31.
3275
59cf8544
PH
3276PH/28 Changed -d+all to exclude +memory, because that information is very
3277 rarely of interest, but it makes the output a lot bigger. People tend to
3278 do -d+all out of habit.

PH
3280PH/29 Removed support for the Linux-libc5 build, as it is obsolete and the
3281 code in os-type was giving problems when libc.so lives in lib64, like on
3282 x86_64 Fedora Core.
3283

PH
3284PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3285 aren't the modern standard, and it seems that some systems' include files
3286 don't always have them. Exim was already checking for some of the newer
3287 ones like T_AAAA, and defining it itself. I've added checks for all the
3288 record types that Exim uses.

PH
3290PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3291 not automatically generating a new one, as it is supposed to. This
3292 prevented TLS from working. If the file did exist, but contained invalid
3293 data, a new version was generated, as expected. It was only the case of a
3294 non-existent file that was broken.

3299TK/11 Domainkeys: Change the logic how the "testing" policy flag is retrieved
3300 from DNS. If the selector record carries the flag, it now has

PH
3305PH/32 In mua_wrapper mode, if an smtp transport configuration error (such as
3306 the use of a port name that isn't defined in /etc/services) occurred, the
3307 message was deferred as in a normal delivery, and thus remained on the
3308 spool, instead of being failed because of the mua_wrapper setting. This
3309 is now fixed, and I tidied up some of the mua_wrapper messages at the
3310 same time.

3312SC/08 Eximstats: whilst parsing the mainlog(s), store information about
3313 the messages in a hash of arrays rather than using individual hashes.
3314 This is a bit cleaner and results in dramatic memory savings, albeit
3315 at a slight CPU cost.

3341
3342PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3343 that changes the way the GnuTLS parameters are stored in the cache file.
3344 The new format can be generated externally. For backward compatibility,
3345 if the data in the cache doesn't make sense, Exim assumes it has read an
3346 old-format file, and it generates new data and writes a new file. This
3347 means that you can't go back to an older release without removing the
3348 file.
3349
3350PH/03 A redirect router that has both "unseen" and "one_time" set does not
