This is for use with ipswitch's imail software, but if you open the zip you will see a file called url-domain-bl.txt which lists thousands of domains to block - including of course cpaemprire.com

There is also a file called phrase-list.txt.

Now these are designed to be used with imail, so be careful in their use, but the domain list is great, you will notice it has cpaempire, but not other non-spammy networks.
