SpamAssassin is very slow, but you only run it on messages that pass

accepting all of it.
If I were deploying it, I would probably just accept the messages that pass
authentication and have adequate sender reputation, and run SpamAssassin on the
rest. Either way, the overhead of signature checking trades off against some
reduction in content filtering.
