Wait, how exactly do you want to test the local server?

The original request was use of dnsdb for checking a particular domain,
for unspecified reasons. If you're checking mail, you should be able to
just use the @mx_primary and @mx_secondary built-in domain-lists,
similar to @mx_any, to test if the domain under consideration is one
where the server which Exim is running on is in the primary MX or any
other.
