Use a mailertable that sends everything for your domain[s] to the
internal server.  The bat book covers this, but so should the sendmail
docs.  I'll point out one usual pitfall though: if you use a mailetable
to route the inbound mail from a gateway host you should not have the 
routed domain[s] in the gateway sendmail's class w.
