Socket connections to most Google IPs are blocked from App Engine, which includes aspmx.l.google.com. However you can connect to smtp.gmail.com on port 465 or 587, which is the recommended way to send GSuite domain email from an app.

If you need to send more mail that the GSuite quota allows, you should use an external mail relay service like Mailjet or Sendgrid.

Further to the above,  aspmx.l.google.com is an inbound mail relay for GSuite / Google Apps, so can only route mail to GSuite domain users or Gmail users.
