Define 'spread the load'. You're taking a perfectly good server (or more), chopping it up into many pieces so you can run many instances of Postfix and Dovecot. If you really need to spread the load, setup two servers with Postfix and Dovecot. It would significantly reduce the complexity, and eliminate your issues with multiple IPs. It would also reduce the bottleneck with the proxy servers. You don't 'spread the load' by setting up tens or hundreds of virtual machines of which each VM handles a few messages per hour. You setup however many servers you need to provide decent response times and service availability. It sounds like you're building a complex system just to build a complex system. -A
