Ben,
the problem is we would use webmin + virtualmin as an interface for
costumers to manage their domain (mainly emails) on the server and
virtualmin don't use/support mysql + vpopmail yet, at least that what
i understand at this moment.
virtualmin choose to use unix system user with postfix, so if i create
an email then it create one unix system user too, this is what i'm
concern, since i don't have any information about what happen to
linux/centos if these unix system user growing bigger and bigger to
reach some thousands users for an example.

no particular reason, i just new to postfix, currently i'm qmail +
vpopmail admin.
i read on postfix and dovecot website about latest stable release and
i installed from source :)
i know that centos have postfix + dovecot + mysql as a rpm package.

these webmin + virtualmin mainly for user interface to manage their
domain on the server (just like control panel on hosting server)
