The smtpd entry needs a rewrite_service_name override that directs queries to its own trivial-rewrite daemon. These smtpd and trivial-rewrite daemons need overrides for all the address class parameters (see ADDRESS_CLASS_README.html). Depending on what you do in the cleanup daemon, this smtpd entry may also need overrides for cleanup_service to direct requests to its own cleanup daemon. And depending on what you do in the queue manager, this cleanup entry may need a queue_directory and queue_service_name overrides to direct requests to its own queue manager with its own queue. If you want to bounce mail with the "right" MTA personality, then everything including delivery agents needs overrides for bounce_service, defer_service, and trace_service, and those need overrides to present the "right" MTA personality. > > unmaintainable mess.
