Up until now, the `sent` event type was never processed, probably because it "made no sense", as an unsent email would never trigger an event.
However, it makes sense to process it because you may have a local relay that transmits mails over to the mail provider. In those circumstances, you should have 2 "sent" events (one from the relay and another one from the provider).
Also marked some useless parts of code for removal.
