There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
The Domain Inspector filter is designed to see if it leads a user to visit a blacklisted site. Therefore, it does both DBL and RBL lookups. Why do you want to do one but not the other?
