Here is what we did.  In /usr/lib/sendmail.cf, add a line that
explicitly defines "w" to be the name of the gateway.  Normally "w" is
the host name, so this has the effect of forcing the reply to be the
gateway.  We originally did this patch to avoid having replied mail go
to diskless nodes that might not be up.  We found we really like it
because it centralizes the sendmail server for all the apollos on a ring
(no one else has to run "sendmail -bd") which makes it easier to
maintain.  But that is because we have found a service that is at 100%
service 90% of the time preferable to one which is at <100% service 100%
of the time.
