6 This file contains descriptions of new features that have been added to Exim,
7 but have not yet made it into the main manual (which is most conveniently
8 updated when there is a relatively large batch of changes). The doc/ChangeLog
9 file contains a listing of all changes, including bug fixes.
14 1. There is a new Boolean option called filter_prepend_home for the redirect
15 router. It defaults true, for backward compatibility. If a "save" command in
16 an Exim filter has a relative path for its argument, and $home is defined,
17 it is automatically prepended to the relative path. This action can now be
18 prevented by setting filter_prepend_home false.
24 1. The ${readsocket expansion item now supports Internet domain sockets as well
25 as Unix domain sockets. If the first argument begins "inet:", it must be of
26 the form "inet:host:port". The port is mandatory; it may be a number or the
27 name of a TCP port in /etc/services. The host may be a name, or it may be an
28 IP address. An ip address may optionally be enclosed in square brackets.
29 This is best for IPv6 addresses. For example:
31 ${readsocket{inet:[::1]:1234}{<request data>}...
33 Only a single host name may be given, but if looking it up yield more than
34 one IP address, they are each tried in turn until a connection is made. Once
35 a connection has been made, the behaviour is as for ${readsocket with a Unix
38 2. If a redirect router sets up file or pipe deliveries for more than one
39 incoming address, and the relevant transport has batch_max set greater than
40 one, a batch delivery now occurs.
42 3. The appendfile transport has a new option called maildirfolder_create_regex.
43 Its value is a regular expression. For a maildir delivery, this is matched
44 against the maildir directory; if it matches, Exim ensures that a
45 maildirfolder file is created alongside the new, cur, and tmp directories.
51 The documentation is up-to-date for the 4.61 release. Major new features since
54 . An option called disable_ipv6, to disable the use of IPv6 completely.
56 . An increase in the number of ACL variables to 20 of each type.
58 . A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1,
59 $2, $3, (though those are still set) because the numeric variables get used
60 for other things in complicated expansions.
62 . The default for rfc1413_query_timeout has been changed from 30s to 5s.
64 . It is possible to use setclassresources() on some BSD OS to control the
65 resources used in pipe deliveries.
67 . A new ACL modifier called add_header, which can be used with any verb.
69 . More errors are detectable in retry rules.
71 There are a number of other additions too.
77 The documentation is up-to-date for the 4.60 release. Major new features since
82 . Support for IGNOREQUOTA in LMTP.
84 . Extensions to the "submission mode" features.
86 . Support for Client SMTP Authorization (CSA).
88 . Support for ratelimiting hosts and users.
90 . New expansion items to help with the BATV "prvs" scheme.
92 . A "match_ip" condition, that matches an IP address against a list.
94 There are many more minor changes.
