Read the authentication headers a receiver added to one message. Headers are unfolded first, because a field continues on any line beginning with whitespace. Reports two From headers, where what is displayed and what is evaluated can differ, which is the shape of a spoof rather than a mistake; a lower Authentication-Results, which can have been written before the message arrived; a result from an untrusted server; and a DKIM or SPF domain that does not align with the From domain.
