   5 # This is used to determine whitelisted senders and hosts.
   6 # It checks for CONFDIR/host_local_deny_exceptions and
   7 # CONFDIR/sender_local_deny_exceptions.
   8 #
   9 # It is meant to be used from some other acl entry.
  10 #
  11 # See exim4-config_files(5) for details.
  12 #
  13 # If the files do not exist, the white list never matches, which is
  14 # the desired behaviour.
  15 #
  16 # The old file names CONFDIR/local_host_whitelist and
  17 # CONFDIR/local_sender_whitelist will continue to be honored for a
  18 # transition period. Their use is deprecated.
