Publish an MTA-STS policy without maintaining a separate web server and TLS certificate. Hosted MTA-STS lets you manage the policy for inbound email delivery from Suped.
Host the policy and verify your setup
Choose your policy mode, specify your MX hosts, and set how long sending servers can cache the policy. Add the two CNAME records shown in the setup dialog, then verify your DNS and mail servers' STARTTLS support.
Hosted MTA-STS configuration with Testing mode, MX hosts, policy preview and DNS setup instructions.
Start in Testing mode while checking your configuration. When you're ready, switch to Enforce to ask supporting sending servers to require a valid encrypted connection to the mail servers in your policy.
Get started
Open Domains and configure MTA-STS for your domain. Follow the setup guide or explore Hosted MTA-STS.
