They've just been incredibly active this past week on the list. What I _think_ happened is one of their ex-customers had a domain with them with an email address, and the domain no longer exists, but the mx record points to them, and ... they get the mail. Anyway, that's my guess based on their reply to 'doesntexist.com' or whatever the header says. 1 & 1 Internet - really, you should try to unsubscribe, though I don't know if you can find the address to do such with.
