Sometimes, I don’t know why I try??

Why is it that Cisco, one of the largest networking companies in the world, cannot resolve a simple hostname in a URL?!?  I submitted a spam email to Spamcop that included the URL “http://www.med72.com/”.  When Spamcop tried to process the email, it said the following:

Finding links in message body

Parsing text part

Resolving link obfuscation

http://www.med72.com/
Host www.med72.com (checking ip) IP not found ; www.med72.com discarded as fake.

Tracking link: http://www.med72.com/

Cannot resolve http://www.med72.com/
Funny, but it resolves for me just fine:
D:\>nslookup www.med72.com
Server:  UnKnown
Address:  192.168.2.1

Non-authoritative answer:
Name:    www.med72.com
Addresses:  60.191.239.150, 61.191.191.241, 218.75.144.6, 119.39.238.2
203.93.208.86

I don’t think Spamcop is trying very hard to fulfill this service (a service that they make plenty of money from).
