[email protected]. How do I get? why does my e-mail show my address as (ATT.net Mail) Customer Center UPDATE ,[email protected]. How do I get it back to just [email protected]? some of my friends accounts do not accept it and since my name is not showing they will not open it. How do I correct this? Thanks for your help.
