[Mailman-Users] Make sure that only our newsletter can be delivered to a mailing-list that is not moderated

[Jacob Friis Larsen]

We will use Mailman to send our newsletter.
This newsletter will be sent from the same server every time.
The mailing-list will not be moderated, as the newsletter will be sent 
automatically by a script, sometimes in the weekend where no staff is at 
work.

How can we secure our list server?
