8,000 users is nothing for a mail system, 5,000 concurrent users is
huge. I don't see how you can get that last number from the first one.
Nevertheless, your problem is more a load balancing issue than a beowulf
one. I'd advice to use a distributed back end to store the mail. A
virtual server as front-end (round robin should be enough) and some kind
of database to tie the stuff (ldap, MySQL come to mind, but others may
be fine).
