Deploying SMTP TLS Reporting

SMTP TLS Reporting is configured via a mechanism called MTA-STS, a simple DNS TXT record.

MTA-STS has a safe 'testing' mode that allows you to gather feedback on the secure delivery of your email with no risk.

After a period of monitoring you can enforce the secure delivery of emails, or, continue to monitor on an ongoing basis.
