Hello Brain, Thanks for the feedback. I have just started today and I will be monitoring the email traffic very closely. Unfortunately, it seems that Google does not support " ruf " tag ( https://support.google.com/a/answer/2466563?hl=en ). My only concerns are the mailing list and email forwarding that I may have some issues. Thanks, --Alex Adao On Wed, Oct 21, 2015 at 10:30 AM, Brian Epstein <bepstein () ias edu> wrote:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi Alex, I haven't deployed DMARC, yet, for the IAS, however, I have deployed it for 5 other organizations that I am a part of. In its first phase, I have made all the DMARC and SPF settings pretty forgiving and am collecting reports from domains to see how my users are doing. Once I gather a few months of details, I'll be in a better position to write better SPF records. I'm always amazed at the number of legitimate third party places that need to send emails as my domain. After identifying those places, I'll probably start locking it down and asking mail servers to start denying email from places not in my SPF records. So, I definitely suggest adding the ruf= stanza to the DMARC record for the trial period at least. Once I'm more comfortable with these other organizations, I'll start the same process for ias.edu.
