Email Server Setup

Hello!

We are currently in the process of setting up our new hosting environment which includes a few cpanel servers. What I am looking to do is have 1 MX Server (mx1.ourdomain.com) which will then distribute emails to 2 or 3 cpanel servers.

Are there any scripts available or addons to cpanel that will generate a list of domain names on the cpanel server and then send it to the MX server so that the MX server then knows which server to route the emails too once it has been through the MX server and had spam filtering and what not applied.

Thanks!
