Sendmail on a specific NIC

I have a Linux box with two network interfaces. By default
everything is routed via eth0. What I would like is to have sendmail
listening on eth1 instead, and for all in/out sendmail traffic to use
eth1 exclusively. Is this possible?

That's a question for comp.mail.sendmail -- setting Followup-To.

It doesn't work like that -- sendmail speaks IP, not Ethernet. If the
IP addresses it listens to are on eth1, and the routes to the IP peers
it needs to talk to go over eth1, then it will use eth1 exclusively.
Not otherwise.

Make eth1 the default gateway?

Which are the IP configurations of eth0 and eth1?

What does the routing table (route -n) look like?
