That was called "Bonded Spammer", from Ironport. They were trying to get ISPs to accept their whitelist.[1] (Ironport tried to call it "Bonded Sender", but nobody in anti-spam took that seriously.)
Ironport was selling mail filtering appliances. They also sold dedicated spamming engines that were whitelisted by the mail filtering appliances. This playing both sides of the street made them something of a joke, and they had to drop the spam engine business. They were eventually acquired by Cisco after that.
