multiple-instances

I recently attempted to reconfigure an existing single-instance Postfix server (multi-homed) to support multiple MTA instances, but failed miserably (read: open relay, nastygram from ISP).

It appears that there are several methods that can be used to accomplish this, and the various (and numerous) secondary sources that I found online were 'all over the map' with respect to which they used/glued together.

Can anyone provide a working configuration (or tips) that use postmulti to manage a multi-instance Postfix setup?
