29563 Correct DNS problem

I have a small problem that I need fixed. My server is running an improper configuration of recursive DNS and I need this corrected. I need this done asap. This is a fairly simple task. Your server has been identified as running an improper configuration of recursive DNS. We allow recursive DNS only when it is run locally and for a specific IP range. If you do not disable recursive DNS on your server or establish the appropriate configuration, we will suspend your account. Your account will remain suspended until you make arrangements with our Advanced Hosting Support to disable recursive DNS.
