I have been using sbcglobal.net for years. Last Oct 21, 2014 I stopped getting mails in my computer Mailbox. I have to go the web to access my mails. I already brought my MAC computer to the computer store to be checked and they said it is up and ready and took it home. When I opened my mail, I still cannot see my incoming mails. I had a live chat with an ATT support guy. He accessed my computer with my permission, but I still have the same problem.Is there a problem with my server?
