[Mailman-Users] Announce-only lists?

You could write a program that reads standard input, removes the From 
address and the Received lines, then forwards the mail to the list 
addresses using the list From address. Hook the program up to a secret 
e-mail address. It should be just as secure as an approval password.

By the way, this interests me, too. I'm not worried about spam; I'm worried 
about jerks sending e-mail to the announce list just because they can (to 
show how smart they are, etc.). There are a lot of people like that, you know.
