Pretty simple question. How do I block all connection attempts to my network from a specific domain with a Cisco PiX 501?

Actually, it's not that simple since the PIX can only block based on source IP address, source port, destination IP address or destination port.  If you can express the domain you want blocked in terms of IP addresses, then you can do it.  But there is no way to block "myspace.com"...you have to give it IP addresses.

That's exactly what I thought. I couldn't find a place in this antiquated piece of... hardware... to do what I wanted to do, I was just hoping I was missing something.
 Our mail server wasn't set up to block some spam properly and in the process of fixing it I was going to block out the spammer entirely.
 What's the command lines to block his IP address any way? Hopefully he's fixed IP and that'll do, and hopefully the fixes I've put in on our mail server will make it moot, but it couldn't hurt to go the extra step...

 Again, to block all traffic to my firewall from a specific IP on the internet... Thanks.
