One thing that too many people forget, and that should be accounted for before changing the DNS entries for an existing domain, is that the mail will not travel with the domain content.
Users need to download and/or forward existing messages somewhere else. If they do not, it will be lost.
For the life of me, I don't know why this hasn't been made easier during the life of the 'net... some way to ftp the mail and move it to the new server.
