So what does this make Postfix do?  Run one instance of dovecot/deliver and
pipe email to it?  Maybe that is the right solution and running it via
mailbox_command is wrong?

So what is virtual_minimum_uid doing for you if virtual_uid_maps is static?
Or why are any of these even relevant if everything is being piped to a
process started via master.cf?

And (problem I posted in a separate thread) does %d get assigned correctly
with the domain name for mail_location = if this method of running
dovecot/deliver is used?
