Majordomo, it appears, is hosted by sparknet.net. A quick check of their domain on the Internet tells us that their sister domain, sparklist, is an email list hosting service.

Create a rule to block messages from majordomo.com, and for that matter, sparknet.net, if you do not want to receive email routed by either of these two domains.
