DELIVERY RIGHTS
       Deliveries to external files  and  external  commands  are
       made with the rights of the receiving user on whose behalf
       the delivery is made.  In the absence of a  user  context,
       the  local  daemon  uses the owner rights of the :include:
       file or alias database.  When those files are owned by the
       superuser, delivery is made with the rights specified with
       the default_privs configuration parameter.
