   5 # route specific domains manually.
   6 #
   7 # The most common application of this router is to handle relaying to nonlocal
   8 # domains that the local host is primary MX for. That means that local
   9 # information needs to be present for a domain to be handled correctly.
  10 #
  11 # That information is put into the optional file /etc/exim4/hubbed_hosts
  12 # which contains key-value pairs of domain pattern and route data.
  13 #
  14 # foo.example: internal.mail.example.com
  15 # bar.example: 192.168.183.3
  16 #
  17 # will cause mail for foo.example to be sent to the host
  18 # internal.mail.example (IP address derived from A record only), and
  19 # mail to bar.example to be sent to 192.168.183.3.
  20 #
  21 # If the file /etc/exim4/hubbed_hosts does not exist, this router is a
  22 # no-op.
