I caanot get a secure e-mail key for my main bellsouth.net e-mail
I cannot get an secure e-mail key for my main bellsouth.net e-mail. For example, my email address is the first eight (8) letters of my last name. However, AT&T thinks my main e-mail address has two additional characters in front of my email address. For example, if my e-mail address were email@example.com, AT&T thinks my main email address is xyabcdefgh.bellsouth.net. HOWEVER, AT&T has the correct email address for contacting me about my telephone bill.
How do I resolve this problem?
