personally, I would use cyrus - in fact, on that scale, I think you
would be making a mistake not to use cyrus or courier.

I would also use LDAP and not mysql as LDAP scales to multiple systems
in case you actually try to do more sophisticated things such as
multiple data stores on different systems and integrating into CentOS
for things like Postfix is simple whereas you are going to have to get
or do a rebuild to make it work with MySQL.

LDAP, cyrus-imapd and postfix are a perfect combination for virtual
users...MySQL is a bad idea.
