Today, I decided to give google apps a try and setup my own kemple.us email. Previously I had the email set to simply forward to my typical gmail, but with google apps, for free, I get up to 50 accounts on my domain and all the usual gmail, calendar, docs, etc features that google offers. Setup was fairly simple with the longest part being waiting on my mx records to update and google to verify the changes. They even let you change the gmail logo to the logo of your choosing which I thought was a nice touch and you can still connect with googles exchange server for push email on the iPhone. I’m trying to consolidate all my emails now to this one email.
Here’s a link that shows the features in the free version and the premier versions.
