Spoofing, phishing, and email fraud can tarnish a company's reputation and lead to financial losses. One of the most effective ways to prevent these threats and protect your email domain is by implementing a DMARC Record (Domain-based Message Authentication, Reporting & Conformance). A DMARC Record helps businesses authenticate their emails and prevent unauthorized sources from sending malicious emails on their behalf. In this blog, we will explore the significance of DMARC Records , how they work, and how they can safeguard your email reputation. 1. Understanding DMARC Records What is a DMARC Record? A DMARC Record is a DNS entry that defines how email servers should handle messages that fail authentication checks. It works in conjunction with SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail) to verify email authenticity....

How to Set Up MTA-STS and TLS Reporting to Identify and Fix Email Security Issues

Image
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. Understanding MTA-STS and TLS Reporting What is MTA-STS? MTA-STS is a security protocol designed to enforce encrypted communication between email serv...
