DESCRIPTION: This subfile records user numbers of those users who have the exclusive privilege of addressing the mail group. Messages sent by other users will reach the group only if forwarded by an authorized sender. The
authorized senders receive all mail addressed to the group.
WARNING: If a group has authorized senders, then remote users will not be able to send messages to it. Any messages sent by a remote user to a group with authorized senders will be rejected.
