6 # This is the main exim4 configuration file based on the 28.08.05 version by
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.
13 # This configuration file brings in the necessary information from
14 # other databases stored in /etc/exim/ and the files distributed by ud-ldap
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
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
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
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
38 # bsmtp_domains - Domains that we deliver locally via bsmtp
41 if nodeinfo['mailrelay']
43 # mailhubdomains - Domains for which we are the MX, but the mail is relayed
44 # elsewhere. This is designed for use with small volume or
45 # restricted machines that need to use a smarthost for mail
46 # traffic. We will relay for them based on ssl cert validation
47 # but we need to teach exim how to route the mail to them. This is
53 # Exim's wildcard mechanism is a bit odd in that to say "any address in
54 # debian.org including debian.org" you must use two patterns,
57 # Also you can only place a * before a . and as the first char in a string.
58 # Wildcards always match last so they may be used as a catchall.
60 # Further details can be found in each of the files.
62 # Usefull exim commands:
63 # exim4 -qf - Try sending all messages right now, including frozen ones
64 # exim4 -bt foo@blah - Write what exim would do if it saw the address
65 # Great for testing virtual domains and forward files
67 # Special Features for users:
68 # .forward-foo - is understood as an extension address for bar-foo@cow.com
69 # .forward-default - is understood to be a catch all for bar-*@cow.com
70 # .procmailrc - with no .forward file invokes procmail for delivery
73 # For virtual domains the first lookup is done against a linear text
74 # database called 'aliases', then .forward files are consulted. Exim
75 # filtering is available for these .forward files only. .forward-default
76 # is the universal catch all for everything not handled.
78 # Heuristic check (none bad enough to cause a hard reject, but in aggregate
79 # will trigger things like rcpt to rate limiting or possibly a reject if
80 # enough hits are triggered.
