Clustered Virtualmin Server for Email

I found a few posts on this, but nothing that 100% answered my question.

I would like to take all the email services (Postfix Mail Server, Dovecot IMAP / POP3 Server, SpamAssassin Filter Server) and run that on a separate server. It would be ideal to have that be automatic, managed from my currently virtualmin install.

I have seen things saying webmin can do it, or cloudmin might be able to, but I have not found anything stating 100% yes or no.
