I know that some campuses have special accounts for alumni who want a university-affiliated email address. For example, yourname@alumni.youralmamater.edu. You might want to contact your university's IT office (or whoever is in charge of distributing email accounts) to see if you can get one generated for you. I was able to keep my myname@hawaii.edu -- the same account I had in college. I just had to let them know that I wanted to keep it active.
