One of my lists has a usenet gateway through AUVM; some of the members like
being able to access the list that way and I can't take the gateway down.
However, it looks like spam sent through the usenet gateway isn't
intercepted by the superb spambusting features of Listserv. Is there some
tactic I could employ that would perhaps subject the usenet posts to
Listserv's anti-spam filtering?
