Yes, postmulti did feel complex exactly up to the point when I actually tried using it -- it was dead simple to understand and use :) Thanks for creating it! I actually arrived at it by first coming to the conclusion that for separating these concerns of handling different classes of mail, I should really be running different servers for them. But since my use case is so small, there's no way I wanted to run different boxes (even virtual) for it. Then I don't remember whether I actually searched for a way to run multiple postfix instances on the same server or just came across it by accident, but in any case then I understood it as the way to implement my dream of separated servers on the same host.
