Non-authoritative answer:
mydomain.com mail exchanger = 10 mail.mydomain.com.

Authoritative answers can be found from:
mydomain.com nameserver = ns.mydomain.com

It said I don't have revDNS

Then it's quite likely you do not have a reverse DNS.

This is my revDNS

No, it's not. What you are showing here is the reverse DNS for your server on a private LAN IP, they want a reverse DNS on your public IP.

OK, that's better but not good news. Those results show that you do have a valid reverse DNS record to your domain so I'm afraid there's nothing I can do for you other than to suggest you open a support case with AOL at the link specified in their error message. If you are listed with them in error they should remove a block on your IP address sending them mail. Just one final question, you're not on a consumer (i.e. domestic) type of service from your ISP are you? If you are AOL does block them as well.
