I have a sugestion. Actually 2. 1 - Alice creates a bait mail like "drop_spam_here(a)bytefocus.com", we send a secret number, she replies and THEN we send our precious spam collection to her. Worst-case scenario, It proves that some hacker has control of Alice's mail server. And in this case, spam is the smaller of her problems. OR 2 - Alice takes a picture of herself doing something silly like carving a commodore 64 in wood or wearing a hat made of meat.. I vote for the second one. Worked with 419 scammers. http://www.boingboing.net/2006/06/28/nigerian_letter_scam.html On Mon, 24 Jul 2006 13:54:34 -0400 Valdis.Kletnieks () vt edu wrote: V> On Mon, 24 Jul 2006 11:59:34 CDT, Paul Schmehl said: V> V> > What does that prove?
