I have opened the support ticket, and two supports answered me. Both of them only said how to set the A record, which I am sure of it.
The problem is: after saving the template, I set the emailforwarding using the tab, then saved, however, the template changed to Domain Parking with golbal Email Forwarding automatically!
I expected such answers from Moniker, so that is why I did not want to open a support ticket like a normal person.
Any advise from members?
