According to AOL this is more than just settings on my end, the entire AOL network is finding something within the emails that would cause them to mark all of the RPF notifications as spam. But they say if the site administration contacts them that they could add The RPF to their whitelist.
The only reason left why the emails from the website you subscribed keeps going to your spam folder is if the email contains attributes that recognized by AOL as spam. I would suggest that you ask the administrator of the website to file a support request at AOL Postmaster as it would seem that they have been blocked by the Postmaster for sending emails in bulk. Please have them to follow the steps below on how to file a support request.
1. Visit http://postmaster.aol.com.
2. Click on the “Postmaster Support Request” link.
3. Under “For Internet Senders (non-AOL members):”, choose the most appropriate reason for your request on the drop down menu.
4. Click Next.
5. Answer the next two questions and fill up the form with the required information.
6. Accomplish the Image Challenge.
7. Click “submit your request”.
AOL Postmaster should be able to resolve this issue by adding them to our whitelist.
