What are the AOL services that you are trying to block?

If you just want to block all access to login.oscar.aol.com then a simple IP
filter will do. Try something like this:

Deny 205.188/16 except ports 25 and 80

What you want to do is impossible with an
off-the-shelf name server, but since you
can have the source to Bind, you are free
to do it yourself.
