I think your second idea of reinstalling and moving users is a much
better idea than trying to get Red Hat 7.2 working on another
machine. While your at it I would also suggest upgrading your version
of Red Hat. If you can't afford Red Hat, Fedora and Cent OS are both
good RedHat like alternatives. Unfortunately I don't have any
experience with moving a sendmail server so I won't be much help there.
