In February 2015 Paul de Weerd calculated Google published 217,088 IPv4 addresses, and 29,710,560,942,849,126,597,578,981,376 IPv6 addresses as valid SMTP servers. See: http://marc.info/?l=openbsd-misc&m=142478407909186 It would be reasonable to state Google (and others) have populated SPF with LIES.

If you don't trust the sending domain, then SPF evaluation is pointless." http://marc.info/?l=openbsd-misc&m=148232868408696 Regards, -- Craig Skinner | http://linkd.in/yGqkv7
