setup qmail on your new server, test it, then put
':big-mail-server.big.net.au' into /var/qmail/control/smtproutes on each
of the little mail servers. Send the qmail-send process a 'ALRM' signal
on each of the little servers.
They should then attempt to deliver all of their outbound SMTP mail to
your big server (thus emptying its queue). You'll then have tested your
big server's ability to cope with large queues and sudden influxes of
mail as well as moved the mail off the smaller machines.
Hope this helps.
