I just got my hands on an ensim powered server. I am crossing over from plesk and its very awkward.

I remotely host my DNS with everydns.net. When I add a site should I have ensim add it to the DNS server? I can get domain.com to work but not www.domain.com.

Any suggestions?

If you are using a third party to do DNS, then there should be no need to even have BIND running. You should just stop the service or stop and hide it. Just SSH in and type "hide_service bind".
