In order to configure sending emails, try either of the following solutions:

  • Use one of Compute Engine's third-party partners (SendGrid, Mailgun, or Mailjet) to set up and send emails through their servers.
  • Use a G Suite account to set up a relay service to send emails through it.

Please note Google Compute Engine blocks 25, 465 and 587 SMTP ports and does not allow outbound connections on them.

Instances still can receive emails, while sending emails from these ports is not allowed.
