This domain shouldn't be flagged as spam--it's used by the web hosting company Site5 (www.site5.com), and possibly other hosting companies, to serve their customers' email accounts. Site5 alone has thousands of customers, from small businesses to personal blogs to large companies--all using this same domain to serve their various email accounts. Some of these customers may possibly be using their accounts to send spam (a violation of Site5's terms of service, as well as pretty much any other reputable hosting company's TOS ), but the vast majority are honest businesses and website owners who simply happen to share a domain with a few rotten apples. Flagging the entire domain as spam puts thousands of innocent people's email accounts in jeopardy of being blacklisted for the bad acts of those few.
