I have a domain, example.com. I thought I might give Google apps a try so I signed up with me@example.com. I set up a friend with friend@example.com in Google apps. I decided I just wanted to manage my own mail so I deleted friend@example.com, cancelled the service for example.com, and deleted the example.com apps account. Now I try to email to me@example.com and Google is giving me an error before it can get to my mail server at myhostingcompany.com. The rejection reply is as follows:
