5Exim version 4.86
6-----------------
7JH/01 Bug 1545: The smtp transport option "retry_include_ip_address" is now
8 expanded.
9
506900af
JH
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18 EXPERIMENTAL_CERTNAMES is withdrawn.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.
cb1d7830
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.

40Exim version 4.85
41-----------------
42TL/01 When running the test suite, the README says that variables such as
43 no_msglog_check are global and can be placed anywhere in a specific
44 test's script, however it was observed that placement needed to be near
45 the beginning for it to behave that way. Changed the runtest perl
46 script to read through the entire script once to detect and set these
47 variables, reset to the beginning of the script, and then run through
48 the script parsing/test process like normal.
49
ac20058f
TL
50TL/02 The BSD's have an arc4random API. One of the functions to induce
51 adding randomness was arc4random_stir(), but it has been removed in
52 OpenBSD 5.5. Detect this OpenBSD version and skip calling this
53 function when detected.
54
a9b8ec8b
JH
55JH/01 Expand the EXPERIMENTAL_TPDA feature. Several different events now
56 cause callback expansion.
57
6286d7c4
TL
58TL/03 Bugzilla 1518: Clarify "condition" processing in routers; that
59 syntax errors in an expansion can be treated as a string instead of
60 logging or causing an error, due to the internal use of bool_lax
61 instead of bool when processing it.
62
0f06b4f2 63JH/02 Add EXPERIMENTAL_DANE, allowing for using the DNS as trust-anchor for
d567a64d
JH
64 server certificates when making smtp deliveries.
65

JH
66JH/03 Support secondary-separator specifier for MX, SRV, TLSA lookups.

bd21a787
WB
75JH/05 Fix results-pipe from transport process. Several recipients, combined
76 with certificate use, exposed issues where response data items split
77 over buffer boundaries were not parsed properly. This eventually
78 resulted in duplicates being sent. This issue only became common enough
79 to notice due to the introduction of conection certificate information,
80 the item size being so much larger. Found and fixed by Wolfgang Breyha.
81
8bc732e8
JH
82JH/06 Bug 1533: Fix truncation of items in headers_remove lists. A fixed
83 size buffer was used, resulting in syntax errors when an expansion
84 exceeded it.
85
a7fec7a7
JH
86JH/07 Add support for directories of certificates when compiled with a GnuTLS
87 version 3.3.6 or later.
88
774ef2d7
JH
89JH/08 Rename the TPDA expermimental facility to Event Actions. The #ifdef
90 is EXPERIMENTAL_EVENT, the main-configuration and transport options
91 both become "event_action", the variables become $event_name, $event_data
aec45841 92 and $event_defer_errno. There is a new variable $verify_mode, usable in
723fe533
JH
93 routers, transports and related events. The tls:cert event is now also
94 raised for inbound connections, if the main configuration event_action
95 option is defined.
774ef2d7 96
eca4debb
TL
97TL/06 In test suite, disable OCSP for old versions of openssl which contained
98 early OCSP support, but no stapling (appears to be less than 1.0.0).
99
8d692470
JH
100JH/09 When compiled with OpenSSL and EXPERIMENTAL_CERTNAMES, the checks on
101 server certificate names available under the smtp transport option
102 "tls_verify_cert_hostname" now do not permit multi-component wildcard
103 matches.
104
e9477a08
JH
105JH/10 Time-related extraction expansions from certificates now use the main
106 option "timezone" setting for output formatting, and are consistent
107 between OpenSSL and GnuTLS compilations. Bug 1541.
108
ad4c5ff9
JH
109JH/11 Fix a crash in mime ACL when meeting a zero-length, quoted or RFC2047-
110 encoded parameter in the incoming message. Bug 1558.

JH
111
112JH/12 Bug 1527: Autogrow buffer used in reading spool files. Since they now
113 include certificate info, eximon was claiming there were spoolfile
114 syntax errors.

TF
149Exim version 4.83
150-----------------
151
152TF/01 Correctly close the server side of TLS when forking for delivery.
153
154 When a message was received over SMTP with TLS, Exim failed to clear up
155 the incoming connection properly after forking off the child process to
156 deliver the message. In some situations the subsequent outgoing
157 delivery connection happened to have the same fd number as the incoming
158 connection previously had. Exim would try to use TLS and fail, logging
159 a "Bad file descriptor" error.
160
7245734e
TF
161TF/02 Portability fix for building lookup modules on Solaris when the xpg4
162 utilities have not been installed.
163
fd5dad68
JH
164JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
165 temporary space as the ACL may create new global variables.
166
5428a946
TL
167TL/01 LDAP support uses per connection or global context settings, depending
168 upon the detected version of the libraries at build time.
169
a3c86431
TL
170TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
171 to extract and use the src ip:port in logging and expansions as if it
8ded8589
TL
172 were a direct connection from the outside internet. PPv2 support was
173 updated based on HAProxy spec change in May 2014.

8ddef691 189TL/05 Rename SPF condition results err_perm and err_temp to standardized

TL
190 results permerror and temperror. Previous values are deprecated but
191 still accepted. In a future release, err_perm and err_temp will be
192 completely removed, which will be a backward incompatibility if the
193 ACL tests for either of these two old results. Patch contributed by
8ddef691 194 user bes-internal on the mailing list.

JH
218JH/12 Expand items in router/transport headers_add or headers_remove lists
219 individually rather than the list as a whole. Bug 1452.
220
221 Required for reasonable handling of multiple headers_ options when
222 they may be empty; requires that headers_remove items with embedded
223 colons must have them doubled (or the list-separator changed).

405TF/01 Fix ultimate retry timeouts for intermittently deliverable recipients.
406
407 When a queue runner is handling a message, Exim first routes the
408 recipient addresses, during which it prunes them based on the retry
409 hints database. After that it attempts to deliver the message to
410 any remaining recipients. It then updates the hints database using
411 the retry rules.
412
413 So if a recipient address works intermittently, it can get repeatedly
414 deferred at routing time. The retry hints record remains fresh so the
415 address never reaches the final cutoff time.
416
417 This is a fairly common occurrence when a user is bumping up against
418 their storage quota. Exim had some logic in its local delivery code
419 to deal with this. However it did not apply to per-recipient defers
420 in remote deliveries, e.g. over LMTP to a separate IMAP message store.
421
1ddeb334
TF
422 This change adds a proper retry rule check during routing so that the
423 final cutoff time is checked against the message's age. We only do
424 this check if there is an address retry record and there is not a
425 domain retry record; this implies that previous attempts to handle
426 the address had the retry_use_local_parts option turned on. We use
427 this as an approximation for the destination being like a local
428 delivery, as in LMTP.
67bd1ab3
TF
429
430 I suspect this new check makes the old local delivery cutoff check
431 redundant, but I have not verified this so I left the code in place.

438
439 When I ran the test suite under the user fanf2, Exim expanded
440 the header to contain my full name, whereas it should have added
441 a Resent-Sender: header. It erroneously treats any prefix of the
442 username as equal to the username.

466 Server implementation by Todd Lyons, client by JH.
467 Only enabled when compiled with EXPERIMENTAL_PRDR. A new
468 config variable "prdr_enable" controls whether the server
469 advertises the facility. If the client requests PRDR a new
470 acl_data_smtp_prdr ACL is called once for each recipient, after
471 the body content is received and before the acl_smtp_data ACL.
472 The client is controlled by bolth of: a hosts_try_prdr option
473 on the smtp transport, and the server advertisement.
474 Default client logging of deliveries and rejections involving
475 PRDR are flagged with the string "PRDR".

753TF/03 Make the exiwhat support code safe for signals. Previously Exim might
754 lock up or crash if it happened to be inside a call to libc when it
755 got a SIGUSR1 from exiwhat.
756
757 The SIGUSR1 handler appends the current process status to the process
758 log which is later printed by exiwhat. It used to use the general
759 purpose logging code to do this, but several functions it calls are
760 not safe for signals.
761
762 The new output code in the SIGUSR1 handler is specific to the process
763 log, and simple enough that it's easy to inspect for signal safety.
764 Removing some special cases also simplifies the general logging code.
765 Removing the spurious timestamps from the process log simplifies
766 exiwhat.

TF
768TF/04 Improved ratelimit ACL condition.
769
770 The /noupdate option has been deprecated in favour of /readonly which
771 has clearer semantics. The /leaky, /strict, and /readonly update modes
772 are mutually exclusive. The update mode is no longer included in the
773 database key; it just determines when the database is updated. (This
774 means that when you upgrde Exim will forget old rate measurements.)
775
776 Exim now checks that the per_* options are used with an update mode that
777 makes sense for the current ACL. For example, when Exim is processing a
778 message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify
779 per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you
780 must specify per_mail/readonly. If you omit the update mode it defaults to
781 /leaky where that makes sense (as before) or /readonly where required.
782
783 The /noupdate option is now undocumented but still supported for
784 backwards compatibility. It is equivalent to /readonly except that in
785 ACLs where /readonly is required you may specify /leaky/noupdate or
786 /strict/noupdate which are treated the same as /readonly.
787
788 A useful new feature is the /count= option. This is a generalization
789 of the per_byte option, so that you can measure the throughput of other
790 aggregate values. For example, the per_byte option is now equivalent
791 to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }.
792
793 The per_rcpt option has been generalized using the /count= mechanism
794 (though it's more complicated than the per_byte equivalence). When it is
795 used in acl_smtp_rcpt, the per_rcpt option adds recipients to the
796 measured rate one at a time; if it is used later (e.g. in acl_smtp_data)
797 or in a non-SMTP ACL it adds all the recipients in one go. (The latter
798 /count=$recipients_count behaviour used to work only in non-SMTP ACLs.)
799 Note that using per_rcpt with a non-readonly update mode in more than
800 one ACL will cause the recipients to be double-counted. (The per_mail
801 and per_byte options don't have this problem.)
802
803 The handling of very low rates has changed slightly. If the computed rate
804 is less than the event's count (usually one) then this event is the first
805 after a long gap. In this case the rate is set to the same as this event's
806 count, so that the first message of a spam run is counted properly.
807
808 The major new feature is a mechanism for counting the rate of unique
809 events. The new per_addr option counts the number of different
810 recipients that someone has sent messages to in the last time period. It
811 behaves like per_rcpt if all the recipient addresses are different, but
812 duplicate recipient addresses do not increase the measured rate. Like
813 the /count= option this is a general mechanism, so the per_addr option
814 is equivalent to per_rcpt/unique=$local_part@$domain. You can, for
815 example, measure the rate that a client uses different sender addresses
816 with the options per_mail/unique=$sender_address. There are further
817 details in the main documentation.

1390
6a3bceb1
PH
1391PH/02 When an IPv6 address is converted to a string for single-key lookup
1392 in an address list (e.g. for an item such as "net24-dbm;/net/works"),
1393 dots are used instead of colons so that keys in lsearch files need not
1394 contain colons. This was done some time before quoting was made available
1395 in lsearch files. However, iplsearch files do require colons in IPv6 keys
1396 (notated using the quote facility) so as to distinguish them from IPv4
1397 keys. This meant that lookups for IP addresses in host lists did not work
1398 for iplsearch lookups.
1399
1400 This has been fixed by arranging for IPv6 addresses to be expressed with
1401 colons if the lookup type is iplsearch. This is not incompatible, because
1402 previously such lookups could never work.
1403
1404 The situation is now rather anomolous, since one *can* have colons in
1405 ordinary lsearch keys. However, making the change in all cases is
1406 incompatible and would probably break a number of configurations.

1411MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
1412 conversion specification without a maximum field width, thereby enabling
1413 a rogue spamd server to cause a buffer overflow. While nobody in their
1414 right mind would setup Exim to query an untrusted spamd server, an
1415 attacker that gains access to a server running spamd could potentially
1416 exploit this vulnerability to run arbitrary code as the Exim user.

MH
1421MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
1422 a directory entry by the name of the lookup key. Previously, if a
1423 symlink pointed to a non-existing file or a file in a directory that
1424 Exim lacked permissions to read, a lookup for a key matching that
1425 symlink would fail. Now it is enough that a matching directory entry
1426 exists, symlink or not. (Bugzilla 503.)

1609PH/29 SMTP synchronization checks are implemented when a command is read -
1610 there is a check that no more input is waiting when there shouldn't be
1611 any. However, for some commands, a delay in an ACL can mean that it is
1612 some time before the response is written. In this time, more input might
1613 arrive, invalidly. So now there are extra checks after an ACL has run for
1614 HELO/EHLO and after the predata ACL, and likewise for MAIL and RCPT when
1615 pipelining has not been advertised.

1630 no error. In previous releases of OpenSSL, SSL_CTX_set_info_callback()
1631 was a macro that became an assignment, so it seemed to work. This has

PH
1689 the response to the final '.' that terminates a message, but only in the
1690 case where the client has not sent further data following the '.'
1691 (unfortunately, this is allowed). However, in many cases there won't be
1692 any further data because there won't be any more messages to send. A call
1693 to select() can be used: if it shows that the input is "ready", there is
1694 either input waiting, or the socket has been closed. An attempt to read
1695 the next input character can distinguish the two cases. Previously, Exim
58eb016e 1696 would have sent an OK response which the client would never have see.

1707PH/01 Two more bugs that were introduced by 4.64/PH/07, in addition to the one
1708 fixed by 4.65/MH/01 (is this a record?) are fixed:
1709
1710 (i) An empty string was always treated as zero by the numeric comparison
1711 operators. This behaviour has been restored.
1712
1713 (ii) It is documented that the numeric comparison operators always treat
1714 their arguments as decimal numbers. This was broken in that numbers
1715 starting with 0 were being interpreted as octal.
1716
1717 While fixing these problems I realized that there was another issue that
1718 hadn't been noticed. Values of message_size_limit (both the global option
1719 and the transport option) were treated as octal if they started with 0.
1720 The documentation was vague. These values are now always treated as
1721 decimal, and I will make that clear in the documentation.

1735PH/01 If a system filter or a router generates more than SHRT_MAX (32767)

1737 is held in a short int, deliveries were likely to be lost. As such a
1738 large number of recipients for a single message is ridiculous
1739 (performance will be very, very poor), I have chosen to impose a limit
1740 rather than extend the field.

2b1c6e3a
PH
1765PH/01 If a server that rejects MAIL FROM:<> was the target of a sender
1766 callout verification, Exim cached a "reject" for the entire domain. This
1767 is correct for most verifications, but it is not correct for a recipient
1768 verification with use_sender or use_postmaster set, because in that case
1769 the callout does not use MAIL FROM:<>. Exim now distinguishes the special
1770 case of MAIL FROM:<> rejection from other early rejections (e.g.
1771 rejection of HELO). When verifying a recipient using a non-null MAIL
1772 address, the cache is ignored if it shows MAIL FROM:<> rejection.
1773 Whatever the result of the callout, the value of the domain cache is
1774 left unchanged (for any other kind of callout, getting as far as trying
1775 RCPT means that the domain itself is ok).

1809PH/11 Callouts were setting the name used for EHLO/HELO from $smtp_active_

1811 probably the interface on which it is arriving) and not to the outgoing
1812 callout (which could be using a different interface). This has been
1813 changed to use the value of the helo_data option from the smtp transport
1814 instead - this is what is used when a message is actually being sent. If
1815 there is no remote transport (possible with a router that sets up host
1816 addresses), $smtp_active_hostname is used.

7befa435 1819 tweaks were necessary in order to get it to work (see also 21 below):
14aa5a05
PH
1820 (a) The code assumed that strncpy() returns a negative number on buffer
1821 overflow, which isn't the case. Replaced with Exim's string_format()
1822 function.
1823 (b) There were several signed/unsigned issues. I just did the minimum
1824 hacking in of casts. There is scope for a larger refactoring.
1825 (c) The code used strcasecmp() which is not a standard C function.
1826 Replaced with Exim's strcmpic() function.
1827 (d) The code set only $1; it now sets $auth1 as well.
1828 (e) A simple test gave the error "authentication client didn't specify
1829 service in request". It would seem that Dovecot has changed its
1830 interface. Fortunately there's a specification; I followed it and
1831 changed what the client sends and it appears to be working now.

1837 address A is aliased to B and C, where B exists and C does not. Without
1838 -v the output is "A verified" because verification stops after a
1839 successful redirection if more than one address is generated. However,
1840 with -v the child addresses are also verified. Exim was outputting "A
1841 failed to verify" and then showing the successful verification for C,
1842 with its parentage. It now outputs "B failed to verify", showing B's
1843 parentage before showing the successful verification of C.

1848
322050c2
PH
1849PH/16 It seems that the options setting for the resolver (RES_DEFNAMES and
1850 RES_DNSRCH) can affect the behaviour of gethostbyname() and friends when
1851 they consult the DNS. I had assumed they would set it the way they
1852 wanted; and indeed my experiments on Linux seem to show that in some
1853 cases they do (I could influence IPv6 lookups but not IPv4 lookups).
1854 To be on the safe side, however, I have now made the interface to
1855 host_find_byname() similar to host_find_bydns(), with an argument
1856 containing the DNS resolver options. The host_find_byname() function now
1857 sets these options at its start, just as host_find_bydns() does. The smtp
1858 transport options dns_qualify_single and dns_search_parents are passed to
1859 host_find_byname() when gethostbyname=TRUE in this transport. Other uses
1860 of host_find_byname() use the default settings of RES_DEFNAMES
1861 (qualify_single) but not RES_DNSRCH (search_parents).

1863PH/17 Applied (a modified version of) Nico Erfurth's patch to make
1864 spool_read_header() do less string testing, by means of a preliminary
1865 switch on the second character of optional "-foo" lines. (This is
1866 overdue, caused by the large number of possibilities that now exist.
1867 Originally there were few.) While I was there, I also converted the
1868 str(n)cmp tests so they don't re-test the leading "-" and the first
1869 character, in the hope this might squeeze out yet more improvement.

PH
1871PH/18 Two problems with "group" syntax in header lines when verifying: (1) The
1872 flag allowing group syntax was set by the header_syntax check but not
1873 turned off, possible causing trouble later; (2) The flag was not being
1874 set at all for the header_verify test, causing "group"-style headers to
1875 be rejected. I have now set it in this case, and also caused header_
1876 verify to ignore an empty address taken from a group. While doing this, I
1877 came across some other cases where the code for allowing group syntax
1878 while scanning a header line wasn't quite right (mostly, not resetting
1879 the flag correctly in the right place). These bugs could have caused
1880 trouble for malformed header lines. I hope it is now all correct.

602e59e5
PH
1882PH/19 The functions {pwcheck,saslauthd}_verify_password() are always called
1883 with the "reply" argument non-NULL. The code, however (which originally
1884 came from elsewhere) had *some* tests for NULL when it wrote to *reply,
1885 but it didn't always do it. This confused somebody who was copying the
1886 code for some other use. I have removed all the tests.

PH
1888PH/20 It was discovered that the GnuTLS code had support for RSA_EXPORT, a
1889 feature that was used to support insecure browsers during the U.S. crypto
1890 embargo. It requires special client support, and Exim is probably the
1891 only MTA that supported it -- and would never use it because real RSA is
1892 always available. This code has been removed, because it had the bad
1893 effect of slowing Exim down by computing (never used) parameters for the
1894 RSA_EXPORT functionality.

1899 to be base64-encoded). Also added, on Timo's advice, the "secured" option
1900 if the connection is using TLS or if the remote IP is the same as the
1901 local IP, and the "valid-client-cert option" if a client certificate has
1902 been verified.

1933
1934PH/30 Exim was sometimes attempting to deliver messages that had suffered
1935 address errors (4xx response to RCPT) over the same connection as other
1936 messages routed to the same hosts. Such deliveries are always "forced",
1937 so retry times are not inspected. This resulted in far too many retries
1938 for the affected addresses. The effect occurred only when there were more
1939 hosts than the hosts_max_try setting in the smtp transport when it had
1940 the 4xx errors. Those hosts that it had tried were not added to the list
1941 of hosts for which the message was waiting, so if all were tried, there
1942 was no problem. Two fixes have been applied:
1943
1944 (i) If there are any address or message errors in an SMTP delivery, none
1945 of the hosts (tried or untried) are now added to the list of hosts
1946 for which the message is waiting, so the message should not be a
1947 candidate for sending over the same connection that was used for a
1948 successful delivery of some other message. This seems entirely
1949 reasonable: after all the message is NOT "waiting for some host".
1950 This is so "obvious" that I'm not sure why it wasn't done
1951 previously. Hope I haven't missed anything, but it can't do any
1952 harm, as the worst effect is to miss an optimization.
1953
1954 (ii) If, despite (i), such a delivery is accidentally attempted, the
1955 routing retry time is respected, so at least it doesn't keep
1956 hammering the server.

1971PH/35 The error "getsockname() failed: connection reset by peer" was being
1972 written to the panic log as well as the main log, but it isn't really

1974 removed the panic log writing for the ECONNRESET error when getsockname()

PH
1977PH/36 After a 4xx response to a RCPT error, that address was delayed (in queue
1978 runs only) independently of the message's sender address. This meant
1979 that, if the 4xx error was in fact related to the sender, a different
1980 message to the same recipient with a different sender could confuse
1981 things. In particualar, this can happen when sending to a greylisting
1982 server, but other circumstances could also provoke similar problems.
1983 I have changed the default so that the retry time for these errors is now
1984 based a combination of the sender and recipient addresses. This change
1985 can be overridden by setting address_retry_include_sender=false in the
1986 smtp transport.

2256 Unfortunately, if there is a major crisis, such as a disk failure,
2257 tcp-wrappers gives "deny", whereas what one would like would be some
2258 kind of temporary error. A kludge has been added to help with this.
2259 Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
2260 554 error is used if errno is still zero or contains ENOENT (which occurs
2261 if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a

2347 autoreply, Exim could try to deliver to a non-existent relative file

2364PH/14 When a uid/gid is specified for the queryprogram router, it cannot be

2367 non-existent - all you got was a failure to exec. I have made two
2368 changes:
2369
2370 (a) Failures to set uid/gid, the current directory, or a process leader
2371 in a subprocess such as that created by queryprogram now generate
2372 suitable debugging ouput when -d is set.
2373
2374 (b) The queryprogram router detects when it is not running as root,
2375 outputs suitable debugging information if -d is set, and then runs
2376 the subprocess without attempting to change uid/gid.

2381PH/16 As discussed on the list in Nov/Dec: Exim no longer looks at the
2382 additional section of a DNS packet that returns MX or SRV records.
2383 Instead, it always explicitly searches for A/AAAA records. This avoids
2384 major problems that occur when a DNS server includes only records of one
2385 type (A or AAAA) in an MX/SRV packet. A byproduct of this change has
2386 fixed another bug: if SRV records were looked up and the corresponding
2387 address records were *not* found in the additional section, the port
2388 values from the SRV records were lost.

PH
2398PH/19 When calculating a retry time, Exim used to measure the "time since
2399 failure" by looking at the "first failed" field in the retry record. Now
2400 it does not use this if it is later than than the arrival time of the
2401 message. Instead it uses the arrival time. This makes for better
2402 behaviour in cases where some deliveries succeed, thus re-setting the
2403 "first failed" field. An example is a quota failure for a huge message
2404 when small messages continue to be delivered. Without this change, the
2405 "time since failure" will always be short, possible causing more frequent
2406 delivery attempts for the huge message than are intended.

PH
2503PH/42 The content-scanning code uses fopen() to create files in which to put
2504 message data. Previously it was not paying any attention to the mode of
2505 the files. Exim runs with umask(0) because the rest of the code creates
2506 files with open(), and sets the required mode explicitly. Thus, these
2507 files were ending up world-writeable. This was not a big issue, because,
2508 being within the spool directory, they were not world-accessible. I have
2509 created a function called modefopen, which takes an additional mode
2510 argument. It sets umask(777), creates the file, chmods it to the required
2511 mode, then resets the umask. All the relevant calls to fopen() in the
2512 content scanning code have been changed to use this function.

2524 The decoded challenge strings are now placed in $auth1, $auth2, etc. as

2547PH/52 Two bugs concerned with error handling when the smtp transport is
2548 used in LMTP mode:
2549
2550 (i) Exim was not creating retry information for temporary errors given
2551 for individual recipients after the DATA command when the smtp transport
2552 was used in LMTP mode. This meant that they could be retried too
2553 frequently, and not timed out correctly.
2554
2555 (ii) Exim was setting the flag that allows error details to be returned
2556 for LMTP errors on RCPT commands, but not for LMTP errors for individual
2557 recipients that were returned after the DATA command.
2558
2559PH/53 This is related to PH/52, but is more general: for any failing address,
2560 when detailed error information was permitted to be returned to the
2561 sender, but the error was temporary, then after the final timeout, only
2562 "retry timeout exceeded" was returned. Now it returns the full error as

2633PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
2634 function verify_get_ident() calls ip_connect() to connect a socket, but
2635 if the "connect()" function timed out, ip_connect() used to close the
2636 socket. However, verify_get_ident() also closes the socket later, and in
2637 between Exim writes to the log, which may get opened at this point. When
2638 the socket was closed in ip_connect(), the log could get the same file
2639 descriptor number as the socket. This naturally causes chaos. The fix is
2640 not to close the socket in ip_connect(); the socket should be closed by
2641 the function that creates it. There was only one place in the code where
2642 this was missing, in the iplookup router, which I don't think anybody now
2643 uses, but I've fixed it anyway.

2704
2705 Received: from [1.2.3.4] (helo=[1.2.3.4])

PH
2798PH/19 Exim expands the IPv6 address given to -bh to its full non-abbreviated
2799 canonical form (as documented). However, after a host name lookup from
2800 the IP address, check_host() was doing a simple string comparison with
2801 addresses acquired from the DNS when checking that the found name did
2802 have the original IP as one of its addresses. Since any found IPv6
2803 addresses are likely to be in abbreviated form, the comparison could
2804 fail. Luckily, there already exists a function for doing the comparison
2805 by converting both addresses to binary, so now that is used instead of
2806 the text comparison.
2807
96776534
PH
2808PH/20 There was another similar case to PH/19, when a complete host name was

3181PH/15 The code I had for printing potentially long long variables in PH/11

3188PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
3189 the configuration file to be ":syslog", then the script "guesses" where
3190 the logs files are, rather than using the compiled in default. In our
3191 case the guess is not the same as the compiled default, so the script
3192 suddenly stopped working when I started to use syslog. The patch checks
3193 to see if log_file_path is "". If so, it attempts to read it from exim
3194 with no configuration file to get the compiled in version, before it
3195 falls back to the previous guessing code."

3244 chmod(), fcntl(), sscanf(), and other functions from stdio.h. These were
3245 picked up on a user's system that detects such things. There doesn't seem
3246 to be a gcc warning option for this - only an attribute that has to be
3247 put on the function's prototype. It seems that in Fedora Core 4 they have
3248 set this on a number of new functions. No doubt there will be more in due

PH
3251PH/27 If a dnslookup or manualroute router is set with verify=only, it need not
3252 specify a transport. However, if an address that was verified by such a
3253 router was the subject of a callout, Exim crashed because it tried to
3254 read the rcpt_include_affixes from the non-existent transport. Now it
3255 just assumes that the setting of that option is false. This bug was
3256 introduced by 4.51/PH/31.

3266PH/30 Exim's DNS code uses the original T_xxx names for DNS record times. These
3267 aren't the modern standard, and it seems that some systems' include files
3268 don't always have them. Exim was already checking for some of the newer
3269 ones like T_AAAA, and defining it itself. I've added checks for all the
3270 record types that Exim uses.

3272PH/31 When using GnuTLS, if the parameters cache file did not exist, Exim was
3273 not automatically generating a new one, as it is supposed to. This

3275 data, a new version was generated, as expected. It was only the case of a
3276 non-existent file that was broken.

3292 same time.

3323
3324PH/02 Installed a slightly modified version of Nikos Mavrogiannopoulos' patch
3325 that changes the way the GnuTLS parameters are stored in the cache file.
3326 The new format can be generated externally. For backward compatibility,
3327 if the data in the cache doesn't make sense, Exim assumes it has read an
3328 old-format file, and it generates new data and writes a new file. This
3329 means that you can't go back to an older release without removing the
3330 file.
3331
3332PH/03 A redirect router that has both "unseen" and "one_time" set does not
3333 work if there are any delivery delays because "one_time" forces the
3334 parent to be marked "delivered", so its unseen clone is never tried
3335 again. For this reason, Exim now forbids the simultaneous setting of
3336 these two options.
3337
3338PH/04 Change 4.11/85 fixed an obscure bug concerned with addresses that are
3339 redirected to themselves ("homonym" addresses). Read the long ChangeLog
3340 entry if you want to know the details. The fix, however, neglected to
3341 consider the case when local delivery batching is involved. The test for
3342 "previously delivered" was not happening when checking to see if an
3343 address could be batched with a previous (undelivered) one; under
3344 certain circumstances this could lead to multiple deliveries to the same
c2c19e9d 3345 address.

3350PH/06 A number of "verify =" ACL conditions have no options (e.g. verify =

3353 reverse_host_lookup/defer_ok". An error is now given when options are
3354 supplied for verify items that do not have them. (Maybe reverse_host_
