[bitfolk] Mail server on Bitfolk

Hi,
I am a (delighted!) relatively new BF user and run two dozen websites under Centos and Virtualmin, with no email as I keep email off my webserver.
I am fed up with Cpanel in multiple ways and want to drop the server where I currently have all my email and mail forwarders.

Is another VPS on Centos with Virtualmin a good route to manage my and my clients’ email?
Or is there a better solution for a mail server?
Cheers
Hugh
