if you want to block people from going to certain www addresses, you can do that in the proxy. if you are not talking about browsing, there is no way to do that, you must resolve the DNS names and use IP addresses in the firewall

If you want to stop email spam, you may use Layer & filtering. But, generally, spam should be handled by email server or spam filtering software. Blocking spam by domain would not help a lot.
