Back in 2013[1] we changed our mail config to force MX lookups for gmail to only use IPv4 addresses. We made these change after hearing reports of higher spam scoring when sending mail via IPv6. Would anyone from Google be able to comment as to whether forcing IPv4 is still needed? Yours kindly, Jesse Hathaway
