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 -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
