	Yes, I have thought of implementing it, but in a bit
	different form...

	Namely I thought of retrieving (daily) DNS zone files for
	COM, ORG, and NET from  rs.internic.net, and looking up
	from there those domains that have spam-heaven's as their
	NS server.  Then producing that into domain-list file,
	and feeding to the policy-maker.sh

	Anybody willing to spend a day at writing that script ?
	I can put it running daily at nic.funet.fi, or at
	www.zmailer.org ...
