For months, we have had intermittent issues sending email to AOL addresses. I have worked with AOL engineers and verified that our DNS (MX records) are correct. We have RDNS and spf record and AOL has verified that they are correct. I have established feedback loops all to no avail. When I contacted AOL yesterday, they said that our IP was blocked for spam. I asked for details so I could investigate as the feedback loop provided no input. NADA. One day I can send to AOL and the next day I cannot. We are having NO issues with any other ISP. Any suggestions?

If they're blocking your site for SPAM, then someone on your IP is sending a SIGNIFICANT amount of emails to AOL users... this can often happen if someone is infected with a virus. Check ALL of your PCs with a couple of different virus detection tools, and malware/adware detectors.

Sorry, I should have included in my original question that we have poured over our outbound smtp logs looking for any spikes or significant traffic and found none. For example, only 40 outbound emails went to AOL servers today. Also, we have centrally managed virus protection and all scanning clean. We do not allow autoforwarding of email to an external address either. Granted, probably a large portion of the email going to AOL has nothing to do with work - but I am still trying to do my best.

There are a number of sites that put IP addresses on spam lists, but another factor is the type of IP address you have. Many servers will not accept connections from mail servers that are stationed on a dynamic IP, i.e. personal cable internet.
Even though your IP may stay the same for months, it is still considered dynamic unless you have signed up for a business account with a static address.
-Search google for spam databases and see if you can find your IP.
-Check with your internet provider if your IP address is considered static or dynamic.
