Start by removing all directors that call transports that do anything
locally -- ie transports with driver = appendfile at the very least --
and probably any directors that call aliasfile. If the only transport
driver called is smtp then all mail must be delivered to another
machine. Then work out exactly where you want the mail to go and set
up suitable smartuser directors.
