Hi,
Does anyone have any experience of using DMARC?
See
http://dmarc.org/overview.html
and
http://www.returnpath.net/blog/intheknow/2012/01/return-path-joins-with-gmail-aol-yahoo-and-microsoft-to-found-dmarc-org-to-help-safeguard-consumers-brands-and-isps-from-phishing/
and
http://returnpath.net/commercialsender/domainassurance/dmarc/
It looks like it is some kind of DNS record that checks if a domain
has SPF and DKIM. If so, I guess a filter could be added to my inbound
SMTP servers so that messages are actioned according to the DMARC
policy (quarentine, reject etc) returned by the sender domains DNS
record.
Thanks,
Oliver
