I agree and have yet another similar setup here. We reject about 80% as well, which helps reduce the load on the servers and on the users who manage their quarantines. We allow users to choose whether to use no filtering, the "pre SA", reject filtering only, or full content filtering with SA. A surprising number prefer to use just the more basic checks and deal with what gets through with their mua.
