Excellent! I wish it would also check the SPF and DMARC parameters. Any chances the author would add this with an upcoming update?

Thanks so much for your contribution!

The add-on does not do any SPF or DMARC checks, but can read the result from the Authentication-Results header, see https://github.com/lieser/dkim_verifier/wiki/Options#read-authentication-results-header.
