You start up N queue-runner daemons; one for each named queue -
as well as the traditional one which runs the un-named queue
and also handle inbound smtp.

Adding to what I said before: your retry config gets a little more
complex if the "back off" signal from the target is more involved than
a refusal-to-connect. RCPT-time 4xx is an issue; Exim treats it as
message-specific not host-specific.
