As per request, here is the full header track of one such suspect message. Replace "foo-bar" with our domain and 111.222.333.444 with our IP address. Since these mails are archived and locatable by google I would rather not post the actual domain and IP publicly. We have enough spammers using us now, I don't need to alert any more to our presence.
