  8. Awesome, solved my problem.
    Google cloud blocked all outbound connection on port 25, I changed default port 25 to port 2525 for Postfix on Google cloud, but I get error in mail log about port 25, I checked the Postfix settings again and I was pretty sure the SMTP port has been changed to 2525.
    Now I know I should use another VPS instead of Google Compute Engine
