first of all just have two different relay_to_domainas (with
different names of course: the name is just a convention), one for
domains of which you have the full user list and the other for those
for which you don't. Also, if you know that their smtp server does
recipient checking at smtp time, add a:
verify = recipient/callout=10s,defer_ok
so that you do not need to accept all recipients if the final server
is up (this will mainly be used to cut spam that tries to circumvent
recipient checking by targeting a secondary MX). Read the recent
thread on recipient callout for some subtleties.

you could put that in the alias file:
auser: :fail: This account has been suspended - [20040421]
