Persistent spammers

Over the last couple weeks I've gotten persistent and annoying spams from a place that is currently at broadcastemailcompany.com (although they have had variations on their domain during that time.) broadcastemailgroupcom and broadcastemailcorporation.com are some of their other recent aliases. They claim in the email that their offer is only for non-profit groups and to excuse the inconvenience if you have received this by mistake. Over the last weekend though, I received 7-10 of these on various postmaster@ and root@ addresses (Plus one sales@ address) for the various domains that I either own or administer for others.

Part of the problem is that there are a few addresses that are required in the specs that someone actually gets the messages going there. I receive that contact information for around 20 domains....

Add www.emailadvertisingagency.org as one of their aliases.
