  just define the smarthost for the internal firewall, ie: in the
  sendmail.cf for the isolated firewall, look for the DS macro and put in
  the name of the firewall that is attached to the Internet. This will
  cause the internal firewall to forward all mail ( that it doesn't know
  how to deliver ) to the Internet connected machine for delivery. 

Hope that helps

PS: this info is relevant to sendmail v8.x.x and/or sendmail on a Sun box
running solaris 2.6 or higher. It may apply to previous versions of
Solaris, but I can't recall at the moment.
