It could, in theory, setup a fake smtp session by stopping it at the RCPT_TO command but : 1) some server accept messages at the first layer to reject them later 2) it does not stop spammers that can easily fake the MAIL_FROM ( and From: ) to be the same of the recipient ( this is actually what they do ). - Davide - 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]
