Of course, the "please authenticate yourself" message could well be from a source unknown to the original sender, so it gets bounced and sends a message back to the original recipient, which rejects it and sends yet another message back to the original sender.... This system was discussed at length on the spamcon-general list not too long ago. There are many significant flaws with it, and many proposed fixes for each of the flaws, but in the end you wind up with something pretty unwieldy and cumbersome and, finally, vulnerable again to spam. --Ron -- Ron Risley [EMAIL PROTECTED] www.risley.net ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
