The following article
illustrates how to configure a new customer account, within your partner
Control Panel, with a domain alias. Domain aliasing, or domain stacking, is creating additional domain names that would point to the primary domain.
1. To begin, you will need to access your Partner Control Panel. Using any web browser, navigate to my.securembox.com.
2. Within the Partner Account Panel, select the Customer List / Editor link under My Customers.
3. Once the customer list has populated with all created customers, highlight the Customer you wish to add Microsoft Exchange services to and click the Edit Customer link.
4. Under the Edit Customer section, you will see several service tabs to choose from. Select the Microsoft Exchange tab. Under Exchange Settings, Manage Domains sections, fill in the desired domain in the provided field and select the + Add Domain button.
Note: Each domain will need to have separate DNS Records configured if they are to receive Emails and set as primary address. You can locate the current MX Records and AutoDiscover records by clicking their respected links.
