Piece of cake.  I have several mail servers answering for as many as
15 domains each.

the file "local-host-names" must contain all domain names sendmail answers for.
you will need to use virtusertable and genericstable to handle this. 
Make your biggest domain the name of the machine.  Make the smaller
one the one you'll have virtusers and generics for.

I can also provide snippets of sendmail.mc to assist.  I suggest
milter for anti-spam anti-virus control.  Since milter works during
message acceptance, it can reject back to the sending system during
the connection vice wait and send a bounce to a user at a domain that
doesn't exist.

You're not seriously considering NFS exporting your mail directory are
you?  Just thinking about that is enough to give me nightmares -- NFS
locking issues and all that.
