Domain email forwarding to remote mail server.
Any email for domain.com must go to remote mail server
remote.server.com as firstname.lastname@example.org.
The current forwarding can only be to an email address or to another
domain, not to a remote server hosting the domain.
We currently have this feature on our mail servers and use it for a lot of clients that have onsite email servers on dynamic ip addresses. We are migrating to WHM / Cpanel and WHMCS and require this so that we can manage everything from one platform.
