Can't receive email on att.net account
My att.net email account was recently hacked. I changed the password and security quesitons, and can log in again but I can't recieve emails since the time of the hack. I can send to other accounts just fine but sending a test message to myself from the account doesn't work and neither does emailing it from a gmail account. I don't have a forward setup in my account, no reply to email address is specified, etc. Please advise.
