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. The ${readsocket expansion item now supports Internet domain sockets as well
15 as Unix domain sockets. If the first argument begins "inet:", it must be of
16 the form "inet:host:port". The port is mandatory; it may be a number or the
17 name of a TCP port in /etc/services. The host may be a name, or it may be an
18 IP address. An ip address may optionally be enclosed in square brackets.
19 This is best for IPv6 addresses. For example:
21 ${readsocket{inet:[::1]:1234}{<request data>}...
23 Only a single host name may be given, but if looking it up yield more than
24 one IP address, they are each tried in turn until a connection is made. Once
25 a connection has been made, the behaviour is as for ${readsocket with a Unix
28 2. If a redirect router sets up file or pipe deliveries for more than one
29 incoming address, and the relevant transport has batch_max set greater than
30 one, a batch delivery now occurs.
36 The documentation is up-to-date for the 4.61 release. Major new features since
39 . An option called disable_ipv6, to disable the use of IPv6 completely.
41 . An increase in the number of ACL variables to 20 of each type.
43 . A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1,
44 $2, $3, (though those are still set) because the numeric variables get used
45 for other things in complicated expansions.
47 . The default for rfc1413_query_timeout has been changed from 30s to 5s.
49 . It is possible to use setclassresources() on some BSD OS to control the
50 resources used in pipe deliveries.
52 . A new ACL modifier called add_header, which can be used with any verb.
54 . More errors are detectable in retry rules.
56 There are a number of other additions too.
62 The documentation is up-to-date for the 4.60 release. Major new features since
67 . Support for IGNOREQUOTA in LMTP.
69 . Extensions to the "submission mode" features.
71 . Support for Client SMTP Authorization (CSA).
73 . Support for ratelimiting hosts and users.
75 . New expansion items to help with the BATV "prvs" scheme.
77 . A "match_ip" condition, that matches an IP address against a list.
79 There are many more minor changes.
