Rejecting outbound mail

So then no one can login remotely, and mail can't be sent from any IP other than 127.0.0.1. That should make it so no one will send spam from my server since all the relay tests show it impossible to relay from.

Well, if there's a vulnerable contact form on your server, it can be abused by spammers, because the mails would then originate from 127.0.0.1...
