How to Set Up MTA-STS and TLS Reporting to Identify and Fix Email Security Issues
Introduction Email security is a critical aspect of modern business communication. Organizations must implement strong security measures to protect their emails from interception, spoofing, and phishing attacks. Two essential protocols that enhance email security are MTA-STS (Mail Transfer Agent Strict Transport Security) and TLS Reporting (TLS-RPT) . These protocols help ensure encrypted email transmission and provide visibility into mail delivery issues. While DMARC Email Security is widely known for protecting domains from phishing attacks, MTA-STS and TLS-RPT offer additional layers of security to safeguard email transmissions. In this guide, we will walk you through the process of setting up MTA-STS and TLS-RPT, how they work, and how they complement DMARC Email Security to strengthen your organization's email infrastructure.
