How about using OpenDNS instead? That's a category you can choose to block.

We may consider blocking webmail services. Don't have an ISA server, but have iptables rulesets. I figure I could gather all the popular webmail IP addresses and drop them, but I have a hunch that the subset of addresses returned in a nslookup for many of the services are a small subset of what is in their round-robin list. Any way to get all of them, aside from probing a bunch of various nameservers all over the net? Tried snagging zonefile with dig, get denied. Phillip Partipilo Parametric Solutions Inc.
