We knew it was coming about a week ago and now it is here, for select testers that is. GMail will now host the email for your domain but you have to sign up to be part of the beta testing. Simply go to the GMail Domain Homepage and sign in with your Google account. It will then ask you some simple questions about your company. Then, there is nothing you can do but wait. They are going to analyze each application to see if you fit the type of testers that they need. I signed up for it so I will let you know if/when I get accepted into the program.
