It means the list was not reachable at that time, and postscreen didn't use dnswl for that connection. If you get these for every query every time, you may be blocked; see www.dnswl.org/license The test lookup for dnswl (and almost every RBL) is # host 2.0.0.127.list.dnswl.org which should respond 2.0.0.127.list.dnswl.org has address 127.0.10.0 -- Noel Jones
