By the way, I like the way Google merges the headers into one, like:

an additional option is:

        https://github.com/fastmail/authentication_milter

very config'able, a typical header appears as:

Authentication-Results: auth-milter.example.com;
    arc=none (no signatures found);
    dkim=pass (1024-bit rsa key sha256) header.d=example.net
      header.i=@example.net header.b=l1y+dUDe header.a=rsa-sha256
      header.s=may2015;
    dmarc=pass policy.published-domain-policy=none
      policy.applied-disposition=none policy.evaluated-disposition=none
      (p=none,d=none,d.eval=none) policy.policy-from=p
      header.from=example.net;
    iprev=pass smtp.remote-ip=yyy.yyy.yyy.yyy (subd.example.net);

    x-return-mx=pass header.domain=example.net policy.is_org=yes
      (MX Records found: mx0a-xxx.pphosted.com,mx0b-xxx.pphosted.com);
    x-return-mx=warn smtp.domain=sg.example.net
      policy.org_domain=example.net policy.is_org=no
      (A Records found: xxx.xxx.xxx.xxx);
    x-tls=pass smtp.version=TLSv1.3 smtp.cipher=TLS_CHACHA20_POLY1305_SHA256
      smtp.bits=256/256


it's a trivial install with cpan ... and plays nicely with postfix.
