You shouldn't have to set up 'mail hosts' for the domains. You should just
need to make sure that WebSTAR Mail will relay mail addressed those domains.
I.e., when the secondary server receives a message for one of the domains that
it's providing back-up for, it will look up the MX records for the domain, see
that there's a server with a lower preference (the primary server), and
attempt to send the message on to the server with the lower preference. I
don't use WebSTAR Mail, so I can't tell you the exact settings necessary to
keep it closed to third-party relays, but still allow it to relay to another
specified server. I don't see any instructions for it on a quick glance at the
WebSTAR manual. You might want to ask about it on the WebSTAR list.
