Make SpamAssassin use SPF results in an Authentication-Results header?

Hello,

as far as I understand, SpamAssassin can recognise and consume incoming
SPF results in an Authentication-Results or Received-SPF header, so that
it doesn’t have to do its own SPF evaluation.

I’m using SpamAssassin in a milter setup with Postfix, and have an SPF
milter that runs before SpamAssassin and that inserts an
Authentication-Results header with the result. Does SpamAssassin really
use this header? How to make sure? Or what is the configuration that
would enable this?

Thank you.

For this to work the Authentication-Results header needs to be above the
Received header or it's not trusted.
