    is your domain?  Or are you using the default microsoft generated domain? Also verify the domain, why isn't it verified?  Wheres the MX record for pointing?

    by:stinkyapeboy is an example and is not our domain.  No, we are not using a MS generated domain.  Our MX records are pointed to anti spam solution, Google Postini.  Thanks.
