Yes I already looked at the docs && code and saw how they match. I figured a "black list address if not received through this host" feature would be a pretty desirable feature for folks especially larger companies with large use bases that have addresses like sales/support etc. I guess I could hack something in but figured I would ask first to make sure the code didn't exist out there somewhere first.
