Those are just results of checks a server added to the mail.
According to those headers they were added by lists.freeradius.org server,
but this message received from outlook.som could already contain these
headers, since these headers go AFTER the Received: line.
You don't need to trust them, they can be faked.
...and spammers will surely start faking them, if anyone chooses to blindly trust such
mail headers.
When I received your mail from this lists, I saw:
Authentication-Results: fantomas.fantomas.sk; dmarc=none (p=none dis=none)

so I know that Authentication-Results: were added by my server after
receiving this mail from apache.org.
