Alongside the required mail records, the DBLinx System Health screen also shows optional records: MTA-STS, TLS-RPT, and records that let mail clients find their settings automatically. Who can do this: the organization's tenant administrators; the DNS owner. Once the records are verified, the MTA-STS policy activates and mail to your domain is carried over an encrypted connection.

## Steps
