Virtualmin redirect www, but not mail - keep mail on system

I posted this in Newbies, but no response.
Maybe some one can help me.

Hello I would like to redirect my home page to a Smugmug gallery but when I do that the mail for my domain doesn’t come through; it gets bounced. SmugMug has a nifty app that installs a template with the registrar, GoDaddy and it works, but unfortunately I can no longer receive mail on my VirtualMin hosted site. I think I have to do things manually: i.e.: remove the template from the registrar and implement a redirect on my server through Virtualmin. The issue is that I can only see how to redirect a website to a url. I only want the homepage: to point to SmugMug and still have my inbound mail come in on the existing server. ( I can log in to Usermin and send mail, but not receive any) . Is this scenario possible? Any clues or tips? Please help.
