I am helping a large financial to prepare for DMARC and strict authentication policies. With SPF and DKIM on the way we would like to publish a DMARC record with a "none" policy.
However, we want to be absolutely sure that the "none" policy does not have any effect on the filtering or presentation of the emails. I heard a rumor that even a "none" policy caused specific warnings to be shown in Gmail or Hotmail, but I was unable to confirm this with testing.
Did anyone in this group also see changes in delivery with a "none" policy? Or can I safely assume that it will have absolutely zero impact on email delivery? I know you can call this a "stupid" question, but there is much at stake, so I need to be 100% sure.
