The queue manager connects to the UNIX-domain socket for a particular
delivery agent such as smtp(8) or local(8), and waits for a response
from a delivery agent that it is ready.
Once a delivery agent responds, it receives the delivery request,
and that is the start of delivery. You can see this only by turning
on verbose logging.
The delivery request contains among many things hints whether to
try to save/reuse a connection, but it is up to the delivery agent
to either ignore that hint (local(8) and pipe(8) don't reuse) or
to pay attention to that hint (as smtp(8) does).

Use multiple instances, and filtered mail will not share the
queue with unfiltered mail, so you know exactly why it is in
an active queue.
