Assuming that Virtualmin doesn't have support for real virtual users or redirecting to MySQL for that then you have three basic choices: 1a) Use a different management interface for managing the Postfix/Dovecot configuration. 1b) Write your own extension for Virtualmin which provides this functionality (essentially a variation on 1a). 2) Stick with the existing mail server configuration which already works with Webmin and Virtualmin. 3) Create user accounts that do not provide an actual shell account (e.g. /bin/noshell). With the number of domains and users you're looking at, this could be a real problem, especially when the usernames might conflict between different domains. If I were in your position I'd be looking at either 1a or 1b.
