That is not a freeradius.org server that I can see, completely different
network even...

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) header.from=spamassassin.apache.org
Authentication-Results: fantomas.fantomas.sk;
dkim=fail reason="signature verification failed" (1024-bit key; unprotected) header.d=nasa.gov header.i=@nasa.gov header.a=rsa-sha256 header.s=selector1 header.b=NZ4tZwLQ;
dkim-atps=neutral
Authentication-Results: fantomas.fantomas.sk; arc=fail smtp.remote-ip=3.227.148.255
Authentication-Results: fantomas.fantomas.sk; spf=pass (sender SPF
authorized) smtp.mailfrom=spamassassin.apache.org
(client-ip=3.227.148.255; helo=mxout1-ec2-va.apache.org;
envelope-from=users-return-126707-uhlar=fantomas.sk@spamassassin.apache.
org; receiver=<UNKNOWN>)
Received: from mxout1-ec2-va.apache.org (mxout1-ec2-va.apache.org [3.227.148.255])
by fantomas.fantomas.sk (Postfix) with ESMTPS id 3245DA00EA
for <uhlar@fantomas.sk>; Thu, 20 Apr 2023 13:47:49 +0200 (CEST)

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

lists.freeradius.org is not spamassassin.apache.org

report to your forwarder not setting correct envelope sender, doh
