Doesn't have to replicate.  SMTP is a store and forward transport.  You can
exploit this behavior and have one server that normally accepts email for
your mailboxes (e.g. you mailbox server), and one that is configured that
should it receive mail, would forward it to the Exchange server.  This could
be a FE server or it could be a separate SMTP MTA.  Either way, it's only
job is to receive mail and in the event that the mailbox server is unable to
accept mail for non-fatal reason, to queue the mail until the mailbox server
is once again operational.  At that time it should dequeue and normal
operation would resume. The non-mailbox server would have a higher MX cost.

Ok i found out abt the MX records implementation. I learnt that 2 MX records
can exist one for each machine having exchange 2000 configured to receive
email for the 2 domains. Both will have some cost issue involved which will
set the priority. I got all that. What confused me now is that how will both
the MAIL SERVERS replicate data amongst one another. Both should contain the
same mailboxes right to be able to replace each other...plz drop in some
