Hello, ok trying to setup a mailman list and want it so it hides the from and sets it the list email.

The docs say this can be done but not how?

Spam-specific posting filters

Code:
Hide the sender of a message, replacing it with the list address (Removes From, Sender and Reply-To fields)
can't for the life of me work out how?

any ideas?

cheers
