That would be this hosting provider: http://www.jaguarpc.com
Topica certainly uses this provider provider for some of their mailings, and Jaguar is also hosting others. I don't know if that makes them good or evil. My own opinion about Topica is that in the 3 years the've been sending mail to my domains, they have gotten incrementally better. Some of their lists are derived from suspect sources, but I never seen them do "broadcast spam" to unrelated addressees. It's the subscribers to daily Astrology, Diet, Jokes, Deals and whatnot that get on the spontaneous newsletter treadmill. This is what I call "sel-inflicted spam". Unsubscribing from Topica newsletters does seem to work, but others may describe it as "listwashing". As a private company and not an ISP, I can take no great effort in allowing or blocking them, as Topica rarely has business related lists of interest to us.
