Excuse me but that is not what should happen. What if the IP does not have a DNS name associated with it? I do run my own mailserver, it does NOT relay and if you try it you get dropped with an error code, I had people try to use it as a relay but even my own ISP only probes it and then went away when they realized it was closed. What AOL should do is (if they really want to prevent spam) to go out to the mailserver that makes the connection and see if they can relay to themselves, if they can then block it, if not let the mail go through. No need to punish the ones who do everything right but who are at the mercy of their ISP. I wouldn't mind having my own fixed IP but they are hard to come by these days.
