[Mailman-Users] closed mailman

[Szilard]

Hello mailman-users,

I would like to set up a mailman list with the following options:
- anyone can send emails to the list
- only the subscribers can check the archive
- only the listadmin can add anyone to the list of subscribers

This listservice would be closed for registration or reading,
but it would be open for incoming emails.
It would be a kind of dropbox with all the advantages of a mailing list.

Is there a way to do this?
I can disable the registration page, but how can I disable the registration
by e-mail?

Curiously:
