[Mailman-Users] How do I change the host_name preference

[Sean Murphy]

In the general options admin page there is a setting "Host name this 
list prefers for email."

When I create a list it uses "calarts.edu" in the field but I would like 
it to automatically use the FQDN "server.calarts.edu".

Is there a way to set it permanently for all new list on creations.

Thanks
