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/exim4/ 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/exim4 are as follows:
21 #  locals - This is a list of domains that are considered local. A local
22 #           domain is essentially one for which deliveries to /var/mail
23 #           will be attempted. The users available for local delivery
24 #           come 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 #  relayhosts - Hostnames that can send any arbitarily addressed mail to
31 #           us. This is primarily only useful for emergency '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 #  submission-domains - Domains for which mail will be accepted via the
36 #           submission port
37 <%- if @is_mailrelay -%>
38 #  mailhubdomains - Domains for which we are the MX, but the mail is relayed
39 #           elsewhere.  This is designed for use with small volume or
40 #           restricted machines that need to use a smarthost for mail
41 #           traffic.  We will relay for them based on ssl cert validation
42 #           but we need to teach Exim how to route the mail to them.  This is
43 #           that list.
44 <%- end -%>
45
46 # From /var/lib/misc / UD:
47 #
48 # mail-forward.db - aliases for @d.o
49 # user-forward.db - aliases for @thishost.d.o
50 #
51 # Note that the BDB files generated by ud-ldap use keys that are not
52 # null-terminated, so Exim needs to use the "dbmnz" lookup type, rather
53 # than "dbm".
54
55 # Exim's wildcard mechanism is a bit odd in that to say "any address in
56 # debian.org including debian.org" you must use two patterns,
57 #   *.debian.org
58 #   debian.org
59 # Also you can only place a * before a . and as the first char in a string.
60 # Wildcards always match last so they may be used as a catchall.
61
62 # Further details can be found in each of the files.
63
64 # Useful Exim commands:
65 #  exim4 -qf  - Try sending all messages right now, including frozen ones
66 #  exim4 -bt foo@blah - Write what Exim would do if it saw the address
67 #                      Great for testing virtual domains and forward files
68
69 # Special Features for users:
70 # .forward-foo - is understood as an extension address for bar-foo@cow.com
71 # .forward-default - is understood to be a catch all for bar-*@cow.com
72 # .procmailrc - with no .forward file invokes procmail for delivery
73 #               automatically.
74
75 # For virtual domains the first lookup is done against a linear text
76 # database called 'aliases', then .forward files are consulted. Exim
77 # filtering is available for these .forward files only. .forward-default
78 # is the universal catch all for everything not handled.
79
80 # Heuristic check (none bad enough to cause a hard reject, but in aggregate
81 # will trigger things like rcpt to rate limiting or possibly a reject if
82 # enough hits are triggered).
