Recommendations

  1. 1Switch your MTA-STS policy from testing to enforce mode

    In testing mode, MTA-STS only reports TLS failures without blocking delivery. Switching to enforce mode ensures that emails are only delivered over encrypted connections, providing real protection against interception.
