I was looking for a backup for my Exchange server. Since this is a test server, I don’t have 100% uptime however I depend on it for my main email address. The domain name was registered at GoDaddy and I was using their email server as a backup and it was working beautifully. However, I cancelled my hosting service with them and doing that, I couldn’t manage the email accounts I had so I was looking for an alternative solution. Mario Cardinal said that Google was now offering a new service called Google Apps where they “host” your domain emails.

I checked them out, registered, associated my domain with the account, manage to go thru the verification process and created the first email accounts in about an hour! Now I have Google’s GMail as a backup service for my Exchange server for free. All I can say is Wow!
