   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).
