It can also happen with some of the brain-dead address verification schemes out there. They connect to you and run a SMTP session up to the RCPT TO: command, and if they don't get an error, they assume the address is valid. These kinds of things usually (but not always) have a null sender address (MAIL FROM: <>). - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
