Sniffer is perfect for that - particularly if you share your spam trap data with us. Put another way, if you allow us to use your spam trap then we will be taking over this work for you. All we need is POP3 account information and some details on how your spam trap was formed so that we can properly classify it in our SPHUD (Spam Processing Heads Up Display). Email us at [email protected] to get a spam trap set up.
