I've been using sympl for some time (started when it was called symbiosis), and I've always been happy with it.

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?

Consider Sympl ( https://sympl.host )
I switched to Sympl from Virtualmin. It handles web and mail but there's
no reason you shouldn't use it for mail only. All admin done by ssh, so
forget it if you really want a web based interface.

Sympl is designed for Debian and uses exim4 and dovecot for mail.
