Possible. But the only 'block' I heard of is that AOL is no longer
accepting e-mail from hosts that do not have 'PTR' records to allow
reverse resolution. This block is a crude, but effective way to block

BTW: AOL includes a long distance phone number in any bounces it sends.
You can use that number to contact a network tech to help you resolve
the issue. I used it once and found the tech very helpful/knowledgeable.
