Sbcglobal.net email access

Yesterday, i received a message that my server could not be accessed. Today I cannot even access my email. I have an sbcglobal.net email address and I cannot access my email. it will not recognize my password. i have tried to reset password but going in circles. I no longer have ATT account and cannot get support from their site.
If you reply to my email, I won't see it. I can only see responses to what has been posted on the site.
