AOL Email Blocking

A while back I enlisted help for setting up a small email list server. It is now complete but only AOL is blocking my outbound email. Using their tools they did not report my IP as having a bad reputation. I applied for white listing my single IP and provided ALL the necessary feedback and white listing was denied. Can anyone here point me to someone to get this fixed. It is a small private email list for a local fire department with all consenting recipients. Robert
