Well, I configured it. Thinking that it needed to be set. Doesn't that
setting do anything ? Or does it only work with some news servers and
not others ? How does one know which news server that works with and
which news server it doesn't work with ?

Could you please explain that a little ? In principle how would
filters help ? Wouldn't all posts from Gmane have the same added
headers ? Those that are from legitimate posters and those that 
aren't ?

Well, looking for "gmane" headers on a post gives me something like...

Path: news.gmane.org!not-for-mail
Approved: news at gmane.org
	by lo.gmane.org with esmtp (Exim 4.50)
	by main.gmane.org with esmtp (Gmexim 0.1 (Debian))
X-Injected-Via-Gmane: http://gmane.org/
X-Gmane-NNTP-Posting-Host: ........
Xref: news.gmane.org .......
Archived-At: <http://permalink.gmane.org/listname>

I have no idea how any of that could help filter out posts that aren't
from legitimate subscribers.  :-(

Regards, John.
