I've written a plugin to do this for majordomo mailinglists: http://www.hjp.at/projekte/qpsmtpd/majordomo/ It's been in use for several years now. Early versions only looked at the envelope sender, but that was surprising to majordomo users (majordomo uses the From: header), so I implemented an alternate check for the From: header. Since then it works flawlessly. Cuts down enormously on the spam the moderators get. I started porting it to mailman, but we never got around to switch our public mailinglists from majordomo to mailman that wasn't finished either. hp -- _ | Peter J.
