Let me be sure I have this right: If mail arrives for user-foo, you want
to accept only if the user has .forward-foo and otherwise reject. Is
that right? Many sites are more relaxed about this, and use the rule that
if .forward-foo does not exist, just deliver the message to user. For
the more relaxed rule, you don't need the checkforward router. You just
need to have local_part_suffix = -* on the subsequent router that
accepts mail for the user.

However, I don't see any real problem with using two routers as you
have, if you want that functionality. After all, it only ever uses one
of them.
