First, I would check your full header to make sure that is the address that the Listserv is sending out the post to, and not just the posted TO address. I suspect that it is your hosting company, or email service that is doing this. It might be some kind of sub domain, are you using some kind of shared web hosting account. I see that Clara.net support address is <mailto:[log in to unmask]>[log in to unmask], and they seem to be doing something similar there. Could the co be a region of the U.K. ? I would contact them and ask them why they are outputting your list mail with the .co. If they don't know what it is about, then would contact the List Owner, of the list that generated this, to see if they made some kind of change in processing the email, although I find this doubtful.
