hello, I would like our website to be hosted on Winhost, but for our email to be directed to our company's Exchange Server. I know to get our domain to point to our website, I need to change the name servers at our domain register to point to ns1.Winhost.com, ns2.Winhost.com, and ns3.Winhost.com. What I don't know is how to then point our mail to our exchange server. I tried creating an MX record (mail.powellfab.com) using our WAN IP, but wasn't able to save it (message said "invalid"). Can you help?
