6 # This is the main exim4 configuration file based on the 28.08.05 version by
8 # It is hand crafted, do not replace with anything generated by a config
10 # It is installed as part of the debian.org package -- don't edit this file
12 # The configuration file uses a set of macros and rules to generate an
13 # acceptable mail environment for debian.org machines. It deviates
14 # considerably from what could be considered a standard exim configuration.
16 # This configuration file brings in the necessary information from
17 # other databases stored in /etc/exim/ right now these are linear text
20 # This file is independent of the local host, it should not be changed
21 # per machine. primary_hostname is used in all places that require per-host
24 # The configuration files in /etc/exim are as follows:
25 # locals - This is a list of domains that are considered local. A local
26 # domain is essential one that deliveries to /var/mail
27 # will be attempted. The users available for local delivery
28 # comes from /etc/passwd and /etc/aliases. Wildcards are not
30 # virtualdomains - This is a list of all virtual domains. A virtual domain
31 # is much like a local domain, execpt that the delivery location
32 # and allowed set of users is controlled by a virtual domain
33 # alias file and not /etc/passwd. Wildcards are permitted
34 # rcpthosts - recipient hosts or relay domains. This is a list of
35 # all hosts that we mail exchange for. All domains that list
36 # this host in their MX records should be listed here. Wildcards
38 # relayhosts - Hostnames that can send any arbitarily addressed mail to
39 # us. This is primarily only usefull for emergancy 'queue
40 # flushing' operations, but should be populated with a list
41 # of trusted machines. Wildcards are not permitted
42 # mailhubdomains - Domains for which we are the MX, but the mail is relayed
43 # elsewhere. This is designed for use with small volume or
44 # restricted machines that need to use a smarthost for mail
45 # traffic. We will relay for them based on ssl cert validation
46 # but we need to teach exim how to route the mail to them. This is
48 # The division of files is designed so that all hosts may share rcpthosts
49 # and relayhosts, these could be replicated automatically if necessary.
51 # Exim's wildcard mechanism is a bit odd in that to say "any address in
52 # debian.org including debian.org" you must use two patterns,
55 # Also you can only place a * before a . and as the first char in a string.
56 # Wildcards always match last so they may be used as a catchall.
58 # Further details can be found in each of the files.
60 # Usefull exim commands:
61 # exim4 -qf - Try sending all messages right now, including frozen ones
62 # exim4 -bt foo@blah - Write what exim would do if it saw the address
63 # Great for testing virtual domains and forward files
65 # Special Features for users:
66 # .forward-foo - is understood as an extension address for bar-foo@cow.com
67 # .forward-default - is understood to be a catch all for bar-*@cow.com
68 # .procmailrc - with no .forward file invokes procmail for delivery
71 # For virtual domains the first lookup is done against a linear text
72 # database called 'aliases', then .forward files are consulted. Exim
73 # filtering is available for these .forward files only. .forward-default
74 # is the universal catch all for everything not handled.
76 # Heuristic check (none bad enough to cause a hard reject, but in aggregate
77 # will trigger things like rcpt to rate limiting or possibly a reject if
78 # enough hits are triggered.
