SpamFilterISP does not effect your DNS settings, go to -  and check your domain(s) for missing or improperly setup DNS settings.

AOL will most likely check the reverse-DNS entry for the IP that is sending them mail. So you should ensure that your outbound server (no t just SpamFilter) has a valid reverse-DNS entry on its public IP address.

One warning with DNSReport .... with SpamFilter, as with most anti spam servers the Connect to mail servers will fail.  I have requested that they change the way they test this but since the action to their test is "Non-RFC", they will not budge.
