   this is one point, that old makenl complains about unpublished without pvt   
   double state of the state field is required, or allow unpublished without pvt   
   requirement

   this is true for old mailers like frontdoor, but is incorrect for mailers like   
   binkd, as binkd doesn't check pvt flags at all   
   if there is a "callable" dnshostname or ip address defined in the config or a   
   binkd compatible nodelist - binkd nodelist compilers ignores the pvt flags for   
   transfering St.Louis Nodelist to binkd format nodelist, so later there is no   
   info available, that a nodelist line has an PVT flag or not.   
      
   Mailers, following the PVT clause are POTS/ISDN mailers only, as they have to   
   use the phone number field to get out a POTS number out of the nodelist   
   and in case an unpublished is there, this node is undialable at all, so a   
   workaround is required -> send the mail to the next higher uplink in nodelist   
   that is the NC's system, or RC's system or ZC's system   
   Within its own net, the next higher link system is probably the hub system

   Bart's system is IP only. With the PVT/Unpublished the IP mailer still   
   connects Bart's system, with or without the PVT flag set in the nodelist   
      
   but a POTS mailer like Frontdoor still can gets confused if no PVT flag is in   
   the nodelist line (!)   
   as Frontdoor will route mail to Bart's system to the next higher level -> Host   
   system   
      
   From the FD doc:   
   "If you have mail for a system listed as hold or pvt (no telephone   
   number) in your nodelist database, the default behavior is to   
   send the mail via the system's host/hub. If the mail to a hold or   
   pvt listed system contains file attaches, the mail packet will by   
   default be placed on hold for the host/hub."   
      
   keep in mind:  FD is a POTS only mailer (!)

   here is a wrong assumtion   
   Binkd connects every PVT system if once a connect info is given   
   Binkd ignores the PVT in total   
   but the POTS mailers aren't aware of missed PVT flags, so these systems   
   reroutes mail dependent of the PVT flag (!)   
   Probably a frontdoor mailer with direct mail to Bart's aka will hold the   
   mail bundle forever, instead of reroute the bundle to the next uplink level   
   (Hub/Host/RC)
