Transferring Gmail to Google Apps with own domain
My hosting plan with Dreamhost had an option of using Google Apps with my own domain. In practice, what I wanted was using Gmail, only with my own domain in the address.
The process of setting up Google Apps with an own domain was straight forward. All I had to do was enable Google Apps for my domain in the Dreamhost admin interface and then sign up for a Google Apps account. I had to upload a HTML-file to the root of my domain to assure that I in fact own the domain.
The big problem I had was that I currently have a Google account that I use both for my HTC Hero and for Gmail. What I really wanted was to be able to migrate that account to my own domain. This was unfortunately not possible as the two accounts are entirely separate.
I could import all of my previous mails from Gmail to the new Gmail through POP, even though it was a big pain. I could also set my old Gmail to forward any new messages automatically to the new address.
I still decided to keep using my Gmail as my primary email address because it is most convenient. The new address will, at least for the time being, stay as a secondary email mainly for this site. It is still very convenient to have an email address with an own domain and still be able to use it from anywhere using the Gmail interface and 7+ GB of storage.
