We use the approach, the actual check happens in Exim and a header is added,
similar headers are removed by the Exim prior to adding to prevent spoofing.

Then we use a custom spam assassin rule to score based on the header
inserted by Exim.

For the checks to run within mailscanner you may have to use a spam assassin
plugin.
