true.
Even if now i have stopped using Google's SMTP Server as a means for 
sending out mails and i have decided to use my local MTA instead, at the 
very moment Google's POP servers receive the mail they still add a 
RECEIVE header revealing the hostname of the server that initiated the 
contact. Correct?

But even so, if we alter for example the hostname of our server to a 
different name then wouldn't Google use that to identify the server thus 
protecting the real identity(hostname that is) of the server that 
initiated the connection?
