How to Secure Mailman Webinterface

Hi Folks,

I'm struggeling around wth Plesk and Mailman... Running a single mailing list on my host I would love to get rid of the web interface running on lists. vhost...

I added a proxy rule to my nginx to that I can reach the web interface via www. This works great but there is still the automatically generated vhost "lists" available.

Ho can I tell nginx _not_ to accept external requests für lists.xxx?

thanx in advance

Mat
