   6 # It checks for CONFDIR/local_host_whitelist and
   7 # CONFDIR/local_sender_whitelist.

   9 # It is meant to be used from some other acl entry.
  10 #
  11 # See exim4-config_files(5) for details.

  13 # If the files do not exist, the white list never matches, which is
  14 # the desired behaviour.
