This will cut down the bounce messages your moderators have to deal with. It also puts a crimp into the automated address trawlers that do a 'subscribe/review/unsub' to get your address lists. The other possibility for reducing the spam load is to make sure that spam never makes it to your Listserv machine in the first place. What we do locally is to check the source of mail against several databases of known open-relay sites (see http://www.mail-abuse.org and http://www.orbs.org for more information). I'm not sure how easy/practical it is to do this under whatever SMTP software you're running on NT - I'm a Sendmail sort of guy. -- Valdis Kletnieks Operating Systems Analyst Virginia Tech
