Don't allow everything, and then try restricting.

Just restrict what you allow in the first place.

Instead of having a localuser Director which accepts for all domains,
put restrictions on it.

How do you organise which users are _allowed_ to accept in each domain?

Is it really just the one user? If it's really just that, then a
"condition" rule which says "if it's NOT this local_part at this
domain". If it's more than one user then this is not scalable, but
there are ways to restrict further. In Exim 3, see section 20 of the
Spec, several options there are of use. In Exim 4, this becomes section
14 of the Spec.
