[Mailman-Users] list management - no subscribtion possible? - Only some moderated should be able to post, possible too?

[Torsten Krah]

Hello, is it possible to get it configured that no one can subscribe to
the list - all subscribtion have to be done by an admin?

I can choose confirm, approval or both - but is there a way to get
"none" ( beside blocking the webinterface for subscrption or removing
the subscribe alias at MTA level ) ?

Is there also a way to have a moderated list, where only some of them
are allowed to post ( and to be moderated ) - one way lists or
announcements should only be made by  a few people but many are on the
list which should not be able to post something ( which have to be
moderated to be discarded or rejected ).

thx for the help

kind regards
