Depends on your sendmail.cf, really. What you typically
need to do is configure internal machines to send all mail that
is *not* destined for somebox.*.your.organization to the firewall.
The firewall, in turn is configured to send all mail that *is*
destined for *.your.organization to the "inside" normally. Then
you may need to advertise MX records pointing to the firewall
as a secondary for internal machines, or just an MX for
your.organization, and have it resolve locally or forward all
mail for *.your.organization or your.organization to some internal
smart mailhub.
