After finding the appropriate section in the bat book, I managed to get
this working really nice.  In .mc, you'd use "define(`MAIL_HUB',`remotehost')dnl",
or modify DH in sendmail.cf.  I managed to get this working across my
whole network in a matter of an hour or so.

I'm really glad I found this, this keeps me from having to worry about NFS mounts
and machines hanging when the NFS server goes down for a reboot/maintenance/
what have you.

I haven't took down sendmail on the mail server yet to see what happens when it's
down (e.g. if the gateway box queues mail/etc.), but I'm about to.

Anyways, got it working.  Thanks for the pointer.
