   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 #  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 nodeinfo['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
  41 #           that list.
  42 <% end %>
  43 # Exim's wildcard mechanism is a bit odd in that to say "any address in
  44 # debian.org including debian.org" you must use two patterns,
  45 #   *.debian.org
  46 #   debian.org
  47 # Also you can only place a * before a . and as the first char in a string.
  48 # Wildcards always match last so they may be used as a catchall.
  49
  50 # Further details can be found in each of the files.
  51
  52 # Usefull exim commands:
  53 #  exim4 -qf  - Try sending all messages right now, including frozen ones
  54 #  exim4 -bt foo@blah - Write what exim would do if it saw the address
  55 #                      Great for testing virtual domains and forward files
  56
  57 # Special Features for users:
  58 # .forward-foo - is understood as an extension address for bar-foo@cow.com
  59 # .forward-default - is understood to be a catch all for bar-*@cow.com
  60 # .procmailrc - with no .forward file invokes procmail for delivery
  61 #               automatically.
  62
  63 # For virtual domains the first lookup is done against a linear text
  64 # database called 'aliases', then .forward files are consulted. Exim
  65 # filtering is available for these .forward files only. .forward-default
  66 # is the universal catch all for everything not handled.
  67
  68 # Heuristic check (none bad enough to cause a hard reject, but in aggregate
  69 # will trigger things like rcpt to rate limiting or possibly a reject if
  70 # enough hits are triggered.
