B2B spam continues to flow in from the spammers selling email lists. This week we’ve added a few more B2B spam domains to the Sloan Marketing list that we use: krystallistonline.com
, crystalcommunicationinc.com
, infoemail.biz
, express-mails.com
, database-media.com
, mygreenmarketers.com
(we had already listed thegreenmarketers.com
).
We also added one domain to our list of servers used to send out their B2B spam: webhostingcloud.biz
.
Often, the domains used in these spams don’t have a web site, and when they do, there’s often no contact information. These most likely aren’t real companies, and it has been speculated that all these domains eventually lead back to one place.
So we again updated the SpamAssassin rules that we use on our filters:
