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.
