I guess I did not explain properly, yes, gmail signs all mail no matter how it is sent, client relaying, direct from web interface, however. And, gmail (google) already as of 2008 rejects ALL paypal and ebay emails that do not pass dkim checks. 

I, however, did not say they had to pass the checks. My statement was merely unsigned. If a message comes from ebay, and it is not dkim signed, then, it's a forgery. That's the logic I want to use.
