I'm pretty sure that this comes from Proofpoint's "URL Defense" system. (Google it.) But I don't understand what you mean by "hostile listname" being "correct". What comes before the __ is usually a URL, and there is also a __ BEFORE the url begins. If you use a graphical mail client (like gmail), you don't see this extra junk, but if you click the url that you see, Proofpoint will check it to see if it is on a list of nasty sites. If you want to see the URL alone with a text client (like mutt), I suggest running all messages through .procmailrc with this recipe:
:0 f | /usr/bin/sed -e "s/__/ /g" This will replace __ with spaces, leaving the url itself standing alone.
