A small company in suburban Philadelphia called Holomaxx recently filed two lawsuits against large webmail providers, complaining that they weren’t delivering mail from Holomaxx. The first suit is against Microsoft and Return Path, and the second suit is against Yahoo and Cisco/Ironport. Neither is going anywhere.
According to the complaints, Holomaxx has been sending bulk mail for ten years. They send about 10 million messages a day, six million to Yahoo, and three million to Hotmail/MSN. That was kind of surprising to hear, since 10 million messages a day would be a fairly large mailer, and nobody I know has ever heard of them. This case generated a fair amount of buzz and we all had the same reaction: Who’s that? The complaints identify specific IP addresses from which they mail; I’ve never seen any mail from any of those addresses, and neither has anyone else I’ve bumped into. (Needless to say, I haven’t asked Microsoft or Yahoo.)
