This case is a little more complicated - the OP has recipient
verification turned on, and the routers are called after a RCPT to
determine if a recipient is valid.
What actually is determined is that a recipient is routeable - in this
case, the 'invalid' recipient is, because it meets the conditions of a
router. The fact that the result of its routing would lead to an NDR
due to the 'fail' redirection isn't relevant - the redirection isn't
processed.
The two suggestions to deal with this situation in an ACL are good.
