[Mailman-Users] Stopping users from sending posts

[Kingsley Tech User]

Hi All

How can i stop subscribers from sending mail to the list?
The thing is that I have a weekly newsletter I want to send 
to the list of subscribers, but I don't want anyone but myself
to be able to send to the list.  It's not gonna be a 
discussion list, but more a newsletter / info update list.

I see in the config that you can either have everyone or only
subscribers sending to the list, but I want nobody but myself
to be able to do this.

Many thanks
