flpd596 DNSBL:RBL 521_is_blocked

Currently our mail server is being blocked (flpd596 DNSBL:RBL 521<myIP >_is_blocked). I have emailed abuse_rbl@abuse-att.net but have not heard back from anyone since 1week ago. I emailed abuse_rbl@abuse-att.net again but this time from the administrator account we use and haven't heard anything back now since 3days. I have several customer using our email services who are unable to email anyone @att.net or @bellsouth.net any assistance would be greatly appreciated.
