Hello Scott,

You want to add the option to record the DMARC policy in the A-R header.  I add it as comment:

Authentication-Results: mail.example.org/x551xr2q019874; dmarc=pass
 (p=quarantine dis=none) header.from=example.com; spf=pass
 smtp.mailfrom=uuuu@example.com

with dis being the disposition.

What will a downstream processor do with the information?

Regards
  Dilyan
