Would it not be easier to code a Postfix policy daemon and use rbl lookups against *.countries.blackholes.us or *.countries.nerd.dk and then return either reject_unknown_reverse_client_hostname or reject_unknown_reverse_client_hostname?

If you don't feel like coding this, then you could use something like postfwd policy (http://www.postfwd.org/) to accomplish/wrap your task.
