Funny they are trying to insist on anti-privacy. Ever since gmail began it has flouted internet policy in including the source IP in email headers. A real help to spammers, no help to anti-spammers.
The only thing I have of G's now is customers who force me to send to gmail addresses and googleapis, which I sometimes have to use to get certain internet services. I would ditch both, given an opportunity. Meanwhile I tell all who stand still long enough not to trust G's "privacy".
