Filtering Received: headers is more of a problem, if you need deeper debugging, but even this can be resolved. And common security enforcements dont fit into the land of common RFCs anyway :) ciao -- Philipp Buehler, aka fips | sysfive.com GmbH | BOfH | NUCH | <double-p> #1: Break the clue barrier! #2: Already had buzzword confuseritis ? ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
