   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 #  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
  33 #           are permitted.
  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

  44 #           restricted machines that need to use a smarthost for mail

  69 # .procmailrc - with no .forward file invokes procmail for delivery
  70 #               automatically.
  71
  72 # For virtual domains the first lookup is done against a linear text
  73 # database called 'aliases', then .forward files are consulted. Exim
  74 # filtering is available for these .forward files only. .forward-default
  75 # is the universal catch all for everything not handled.
