    These are the only two IPs I see associated with smtp.gmail.com. ports: 587, 465 and 25 will allow connectivity https://support.google.com/mail/bin/answer.py?hl=en&answer=13287 Are you sure the policy is NATing? You can debug the packet flow through the firewall (policies) via the CLI:
      diag debug enable  diag debug console timestamp enable  diag debug flow filter addr 74.125.47.108 74.125.47.109  diag debug flow show console enable  diag debug flow trace start 1000  
    When you are finished:
      diag debug flow show console disable  diag debug flow trace stop  diag debug flow filter clear  diag debug disable
