It depends on what you mean by "up stream"...  If the "up stream" 
machine is also an internal server, you may be able to set 
your server to use the upstream server as its smart host: 

  http://www.faqs.org/docs/linux_network/x15291.html#AEN15362

Breifly, assuming you're using M5 to configure your sendmail: 

  define(`SMART_HOST', `upstream-server.example.com') 

If this doesn't work, off the top of my head I can't think of much 
else you can do...  It's the upstream that's rejecting, that's where 
you'd need to make the config changes.  Presumably you don't control 
it, in which case you'll be largely out of luck.  Or if you can get a 
DNS name that will resolve internally, that should fix it. 

If the upstream server is NOT also an internal server, and has no hope 
of resolving your IP even with private DNS, then use your internal 
mail gateway machine as your smart host.  Depending on how it's 
configured, you may still need to get a DNS host name that resolves 
internally.
