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 ...
