Oh, absolutely. I just wanted to point out that if you're communicating with google, you're communicating with google -- so even if they enable perfect forward secrecy over smtp/tls -- that's not a 100% fix.

It is still better than them not enabling it -- because if we can assume they do not log the data by default, on their own (aka: we can trust google) -- old data won't be accessible once a (theoretical) new warrant arrives.
