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
