Moving, can I keep my @att.net e-mail address?

I'm going to be moving in the next few months.  Most of the places I'm looking at are more rural and don't have AT&T U-Verse or DSL internet available.  I've had this @att.net e-mail address for years, it dates back to dial-up days, and for a period before U-Verse I was paying to keep it, then when i got U-Verse it got merged into my account.  So, this e-mail is my login to all of my AT&T services, and unfortunately, I've tied a lot of other things to it also.  I will be keeping my AT&T Wireless service (it may well become my primary internet service), but is there a way I can keep my @att.net e-mail address?  Even if I have to pay a small fee for it?  I'm willing to do that even if it gives me some time to transition them all to something like gmail.
