  One our machines here is having problems with sendmail not being able
to find a host unless it is completely specified.

  Example of the problem:

   % mail me@jupiter
  
  this returns with "550 me@jupiter... Host unknown"

  Our system is a Sun 4/390, running SunOS 4.1.1.

  We are using sendmail.mx as our sendmail'er, and are using NIS with
the "-b" option.  Everything else (ping, telnet, etc) work find.

  My guess is that for some reason sendmail can't find the alias for
jupiter.tamu.edu in the /etc/hosts file, or the yp database.

  Is there a way to "force" the NIS to include the aliases if it by default
isn't?

perplexed,
