Is there anything Dovecot itself can do to reject or handle mail to invalid virtual users?
Not directly - the solution, as you surmised, earlier, is to use the same db backend for your users.
Or does this situation *have* to be dealt with earlier, by the MTA?
Yes, it *must* be done at the MTA, otherwise you accept-then-bounce, which makes you a backscatter source, and will quickly get you blacklisted...
