In fact it is trivial-rewrite(8), not virtual(8). There is no point in setting: local_transport virtual_transport relay_transport default_transport in master.cf, since these settings are effectively global, there is only one queue manager which makes transport decisions, and qmgr consults a single trivial-rewrite service. -- Viktor.
