What’s changing

Earlier this year, we announced that Gmail would be enforcing the MTA-STS security standard in beta. We’re now adding a diagnostics page for all admins to validate their MTA-STS configurations.

Who’s impacted

Admins only

Why you’d use it

On this page you can validate your MTA-STS and TLS reporting configuration. If any of your domains are not configured correctly, you’ll see what the suggested configuration is, making it easier to configure new MTA-STS settings.

How to get started

  • Admins: In the Admin console, navigate to Apps > G Suite > Settings for Gmail > Advanced settings. Here, you’ll be able to validate your MTA-STS configuration.
  • End users: No action needed.
