How about: "Dear gmail team, v6 mta operators have noticed that there is a substantial difference between how spam detection is handled for ipv4 and ipv6 connections and this appears to be causing problems with high rates of false positives on v6 sessions. These problems appear to be specific to gmail and are not seen with connections to other major mail operators. Where SPF/dkim are not feasible/possible, this causes people to either implement gmail specific hacks or else disable ipv6. Both these workarounds act against the interests of both Google and the internet at large. Can you please reach out to the ipv6 operator community about this?" ? Nick
