You know I just had a thought. While I agree w/ my first idea that a spammer just sent it out wrong, it could be a different tactic. 1) The mail might get auto-whitelisted. 2) It may be somehow fed into bayes as ham. Spammer could send out the exact same email only now it would get a AWL hit and ham hit. I've saved these blank ones. I'll have to keep an eye out for duplicates with content. $.02 Chris ------------------------------------------------------- This SF.Net email sponsored by: Parasoft Error proof Web apps, automate testing & more.
