       Search the named access database for the client hostname, parent
       domains, client IP address, or networks obtained by stripping least
       significant octets. Reject the request if the result is REJECT or
       "[45]XX text".  Permit the request if the result is OK or RELAY or
       all-numerical. Otherwise, treat the result as another list of UCE
       restrictions. The access_map_reject_code parameter specifies the
       response code for REJECT results (default: 554).
