    Are you troubleshooting why your DKIM signature is not passing validation tests?

    If you are getting the error "The p= field must be base64 encoded" that is most likely because of extra lines or white space, for example:

    In this case it appears the p= was broken into multiple lines. Try moving the white space and retesting.
