My understanding is: smtp-session gets opened from a MUA or MTA via one of the ports exim listens on: delivery process gets started because of the smtp-session

A mail couldn’t be delivered and sits in the queue: queue runner starts it at some point

Administrator runs something like “exim -M $message-id” and a delivery process gets started.

Best,
