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 “”.  When Spamcop tried to process the email, it said the following:

Finding links in message body

Parsing text part

Resolving link obfuscation
Host (checking ip) IP not found ; discarded as fake.

Tracking link:

Cannot resolve
Funny, but it resolves for me just fine:
Server:  UnKnown

Non-authoritative answer:

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