And as I gather from their web site, it's also how Gmane allows non
list member Gmane users to post back to the list through Gmane. Posts
that come through Gmane to your list apparently are sent from Gmane
with the SMTP command "MAIL FROM rpg400 at m.gmane.org" which makes that
address the envelope sender and therefore, allows anyone to post to
your list via Gmane according to their rules, not yours. This appears
to be the price you pay for "archiving" your list with Gmane.
