I am one of the listowners of a number of lists which are broadcast-only. It appears from some bounces I received today that someone tried to spoof the address of one of the editors and post to one of the lists. I don't want this to happen, and would like to set up a keyword or combination thereof which would require any editor posting to the list to submit a cookie, but which would *not* affect list maintenance commands such as ADD, DELETE, etc. Is this possible?
