I am trying to configure listserv to hide the server name that it is
     running on.  I am running into problems with messages originating from
     listserv containing @@host.bna.com instead of [log in to unmask]

     Is anyone running listserv behind a firewall, and aliasing it to
     listserv@domain instead of a separate machine name?

     Are there any settings that my listserv owner will need to make to the
     go.user file or other configuration not available to a list owner?

     The system is running on a SPARCstation-20, using SunOS 5.5.1, using
     sendmail.
