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 PH/01 There is a new global option called disable_ipv6, which does exactly what
15 its name implies. If set true, even if the Exim binary has IPv6 support,
16 no IPv6 activities take place. AAAA records are never looked up for host
17 names given in manual routing data or elsewhere. AAAA records that are
18 received from the DNS as additional data for MX records are ignored. Any
19 IPv6 addresses that are listed in local_interfaces, manualroute route
20 data, etc. are also ignored. If IP literals are enabled, the ipliteral
21 router declines to handle IPv6 literal addresses.
23 PH/02 There are now 20 of each type of ACL variable by default (instead of 10).
24 It is also possible to change the numbers by setting ACL_CVARS and/or
25 ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you
26 upgrade to this release with existing messages containing ACL variable
27 settings on the queue. However, going in the other direction
28 (downgrading) will not be compatible; the values of ACL variables will be
31 PH/03 If quota_warn_message contains a From: header, Exim now refrains from
32 adding the default one. Similarly, if it contains a Reply-To: header, the
33 errors_reply_to option, if set, is not used.
35 PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators,
36 containing the same values as $1, $2, $3. The new variables are provided
37 because the numerical variables can be reset during string expansions
38 (for example, during a "match" operation) and so may lose the
39 authentication data. The preferred variables are now the new ones, with
40 the use of the numerical ones being deprecated, though the support will
41 not be removed, at least, not for a long time.
47 The documentation is up-to-date for the 4.60 release. Major new features since
52 . Support for IGNOREQUOTA in LMTP.
54 . Extensions to the "submission mode" features.
56 . Support for Client SMTP Authorization (CSA).
58 . Support for ratelimiting hosts and users.
60 . New expansion items to help with the BATV "prvs" scheme.
62 . A "match_ip" condition, that matches an IP address against a list.
64 There are many more minor changes.
