title: Google Compute Email Forwarding
body: <p>I've noticed on the <a href="https://cloud.google.com/compute/docs/networking#blockedtraffic" rel="nofollow">Networking and Firewalls</a> page that Port 25 (outgoing) is blocked on Google Compute instances. <br />
  I've configured postfix to forward emails on my instance, but I assume this won't work due to this port blocking, what are my options if I want my emails to forward (or at least work)?</p>
