That's been the good news: Most lists are using a fairly small set of
headers. I expected it to be a far more difficult task.
Hah! Have you tried looking at this list's headers?
Good point. I'm not after spam detection, only list detection. Spam
detection is happening earlier in the process (spamassassin & bogofilter
in my case).
They all can be faked, of course. I have had some spam come
that is a very good fake of some known lists.
