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. cheers, BM
