Re: DMARC Deployment

[Alexandre Adao <alexandre.adao () MORGAN EDU>]

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
