Stronger email security
MTA-STS helps ensure that email is delivered over encrypted SMTP connections, reducing the risk of interception or tampering in transit.
Protection against downgrade attacks
It prevents attackers from forcing email delivery to fall back to unencrypted connections.
Lower risk of man-in-the-middle attacks
By requiring authenticated TLS, MTA-STS makes it harder for attackers to intercept or alter email between mail servers.
Better privacy for sensitive data
Customer and business communications are less exposed while traveling between servers.
Improved trust and security posture
Using MTA-STS and TLS-RPT shows that your organization takes email security seriously, which can strengthen customer confidence.
The setup is easy.
