"Unrouteable address" is the default message that is screwed into the
Exim code. It does not make sense to change it to "Unknown user" because
Exim doesn't know that that is what the problem actually is. All it
knows is that it couldn't route the address. It doesn't try to figure
out exactly what your router configuration tried to do before it failed.

There are configurations that do no local deliveries at all (e.g. relay
systems). "Unknown user" on such a configuration would be most
misleading.

I'm afraid this is one of those cases where the sysadmin has to make a
choice, either in the ACL or by using the cannot_route_message option
on a router.
