Many of the proponents of SPF, and now DMARC, are these large providers who have essentially captive user bases and a level of central control where they can require them to use only their systems to send mail using their domains. If you're an organization that doesn't have that level of centralization (such as, in my case, a university) then SPF or DMARC are much more problematic. You can't publish a restrictive SPF record for the domain as a whole because there are too many different subdomains operating essentially independently of any central IT organization, and publishing a non-restrictive SPF record is kind of pointless. _______________________________________________ Tech mailing list Tech@lists.lopsa.org https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
