Re: F means filtered ?

I think actually the question that Jim was asking is whether Paul filters access to the root name server he runs based on his Spam Blacklist. It seems to be a valid question.

Yes, I do. I have no opinion on whether spammers should or should not be able to reach any given root name server, including "mine", but for the time being I lack the hardware needed to firewall f.root-servers.net differently than I do the rest of my network.
