Find Destination Server Hostname

When setting up your domain(s) in Mail Assure you need to specify the address of the destination mail server that mail should be delivered to.

Be aware, this is not relevant if using Outbound Filtering only. If you do not use Mail Assure for Incoming Filtering, the Destination Server Hostname is not relevant.
