Hi All,

Yes Gmail started adding dmarc information to Authentication-Results
header. It is amazing that you noticed the change just a couple of days
after the launch!
This is our first experiment and I am pretty sure the format of the data
will evolve in the future. We are open for suggestions.
Let me explain the new record:

dmarc=fail (p=REJECT dis=none) d=junc.eu
dmarc=fail -- DMARC authentication failed.
d=junc.eu  -- we applied dmarc policy for junc.eu domain
p=REJECT  -- junc.eu published 'reject' policy
dis=none (disposition=none) -- means that Gmail applied "none" policy
instead of "reject". Most probably this happened because the message was
forwarded.

Finally the message ended-up in the spam folder based on some other
conditions, not related to DMARC.

Please let me know if you have questions.
Thank you,
 Olga
