Google Compute Engine (GCE) email delivery solution?

Question

I\'ve just setup several instances on Google Compute Engine and getting trouble with email delivery system since GCE blocks outbound connections on ports 25, 465, and 587.

We've updated our documentation to include SendGrid as an additional option. You probably want to take another look.
