6 # This is the main exim4 configuration file based on the 28.08.05 version by
7 # ametzler
8
9 # The configuration file uses a set of rules to generate an
10 # acceptable mail environment for debian.org machines. It deviates
11 # considerably from what could be considered a standard exim configuration.
12
13 # This configuration file brings in the necessary information from
14 # other databases stored in /etc/exim/ and the files distributed by ud-ldap
15
16 # This file is independent of the local host, it should not be changed
17 # per machine. primary_hostname is used in all places that require per-host 
18 # settings.
19
20 # The configuration files in /etc/exim are as follows:
21 #  locals - This is a list of domains that are considered local. A local
22 #           domain is essential one that deliveries to /var/mail
23 #           will be attempted. The users available for local delivery
24 #           comes from /etc/passwd and /etc/aliases. Wildcards are not
25 #           permitted.
26 #  virtualdomains - This is a list of all virtual domains. A virtual domain
27 #           is much like a local domain, execpt that the delivery location
28 #           and allowed set of users is controlled by a virtual domain
29 #           alias file and not /etc/passwd. Wildcards are permitted
30 #  rcpthosts - recipient hosts or relay domains. This is a list of
31 #           all hosts that we mail exchange for. All domains that list
32 #           this host in their MX records should be listed here. Wildcards
33 #           are permitted.
34 #  relayhosts - Hostnames that can send any arbitarily addressed mail to
35 #           us. This is primarily only usefull for emergancy 'queue
36 #           flushing' operations, but should be populated with a list
37 #           of trusted machines. Wildcards are not permitted

44 #           restricted machines that need to use a smarthost for mail

67 # .forward-foo - is understood as an extension address for bar-foo@cow.com
68 # .forward-default - is understood to be a catch all for bar-*@cow.com
69 # .procmailrc - with no .forward file invokes procmail for delivery
70 #               automatically.
71
72 # For virtual domains the first lookup is done against a linear text
73 # database called 'aliases', then .forward files are consulted. Exim
74 # filtering is available for these .forward files only. .forward-default
75 # is the universal catch all for everything not handled.

77 # Heuristic check (none bad enough to cause a hard reject, but in aggregate
