I am assuming from this last comment that you don't want to touch
(much) the sendmail.cf on these client machines.  If that is the case,
you do need to modify them a bit so that all mail for the outside
world (at least) goes through one or more Mail Hubs which run a
sendmail.cf that you *are* willing to modify to handle this.

On the Mail Hub(s) you need to:

	Have an alias for everyone who might send mail out (since mail
	will come in to user@domain now).

	Modify the sendmail.cf to rewrite all mail to
	user@something.domain to be just user@domain.  Do this in
	the sendmail.cf mailer rewriting rules for the particular
	mailer.

We've found it best to run the same client sendmail.cf on all clients.
