This settings page is only available to domain administrators, mailing list moderators and system administrators with the proper permissions.
Administrators (list, domain or system) can restrict the posting privileges for a mailing list to Anyone, Subscribers Only or Moderators Only. In addition, they can use the Banned Users section to specify additional blacklisted posters.
To prevent users from posting to a mailing list, use the Banned Posters tab.
To add a new banned user, use the New button and enter the email address(es) of the people who cannot post messages to the mailing list. Be sure to save your changes.
