In exim4, it is possible to do :fail: Custom error message as the
alias return value - I've used it quite often on some systems,
particularly for frequently-made typos.

Postfix seems to be very limited in this respect. By aliasing them to
"|exit 77" you might be able to return "permission denied" rather than
simply "user unknown" but I'm not sure whether that's enough to
actually hard-bounce a message.
If anyone knows how to do it with postfix, I'd like to know too!
Thanks,
