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 # relayhosts - Hostnames that can send any arbitarily addressed mail to
31 # us. This is primarily only usefull for emergancy 'queue
32 # flushing' operations, but should be populated with a list
33 # of trusted machines. Wildcards are not permitted
34 # bsmtp_domains - Domains that we deliver locally via bsmtp
35 <%- if @is_mailrelay -%>
36 # mailhubdomains - Domains for which we are the MX, but the mail is relayed
37 # elsewhere. This is designed for use with small volume or
38 # restricted machines that need to use a smarthost for mail
39 # traffic. We will relay for them based on ssl cert validation
40 # but we need to teach exim how to route the mail to them. This is
44 # Exim's wildcard mechanism is a bit odd in that to say "any address in
45 # debian.org including debian.org" you must use two patterns,
48 # Also you can only place a * before a . and as the first char in a string.
49 # Wildcards always match last so they may be used as a catchall.
51 # Further details can be found in each of the files.
53 # Usefull exim commands:
54 # exim4 -qf - Try sending all messages right now, including frozen ones
55 # exim4 -bt foo@blah - Write what exim would do if it saw the address
56 # Great for testing virtual domains and forward files
58 # Special Features for users:
59 # .forward-foo - is understood as an extension address for bar-foo@cow.com
60 # .forward-default - is understood to be a catch all for bar-*@cow.com
61 # .procmailrc - with no .forward file invokes procmail for delivery
64 # For virtual domains the first lookup is done against a linear text
65 # database called 'aliases', then .forward files are consulted. Exim
66 # filtering is available for these .forward files only. .forward-default
67 # is the universal catch all for everything not handled.
69 # Heuristic check (none bad enough to cause a hard reject, but in aggregate
70 # will trigger things like rcpt to rate limiting or possibly a reject if
71 # enough hits are triggered.
