RMA Plus for Alliance 

The Relationship Management Application (RMA) gives you a level of control that previously did not exist with Bilateral Key Exchange (BKE).

With RMA, you can control who can send you authenticated FIN traffic. RMA blocks unwanted traffic at the sender level, and thus shields you from the potential negative consequences of such unwanted traffic.

RMA Plus goes one step further, and also allows you to control what a correspondent can send you.

With RMA Plus, you can specify exactly which authenticated FIN message types a correspondent is allowed to send you. Unwanted messages will be blocked at the sender level, even if your correspondent does not have the RMA Plus option.
