/**
 * One mail this installation sent.

 * inside the console. Before this, the only record was whatever `sent_at`
 * column the feature in question happened to keep — one per feature, only for
 * the features that thought of it — and everything else lived in the mail
 * server's log on another machine.
 *
 * Written from the MessageSent event, so a row here means the transport
 * accepted the message. That is the strongest claim an application can honestly
 * make; what the receiving server did with it afterwards is not ours to know,
 * and a column called `delivered` would be pretending otherwise.
