[buug] mail servers for boxes with MX records?

I just set up Bind 9 on a network here. My next task is to set up the
mail server. Before I go into this I have one issue that I'd like to

My network looks something like this:

                  [ box1 ]
        [ box0 ]- [ box2 ]
                  [ box3 ]

box0 serves as the firewall, gateway, and dns server, and it is the
machine I wish to set up the mail server on. I'm planning on adding MX
records for the other machines so that they all point to box0.

Now here is what I am not sure about: I know that box0 will have a mail
server runing, but do the other boxes need to have a mail server running
on each of them as well?

What I'm concerned about is mail that is sent from box2 to some local
user (i.e. user at box2.foo.org) should correctly go to user at foo.org. Will
the MUA on box2 realize that box0 is the mail server, and send the mail
there? Or do I have to set up a mail server on box2 as well for this to
work? (i.e. do I set up 4 mail servers or just one?)
