What is one of the primary benefits of using DMARC for email authentication?

Using DMARC (Domain-based Message Authentication, Reporting & Conformance) for email authentication provides several advantages, with control over reporting and visibility being one of the primary benefits. DMARC allows domain owners to request reports from email receivers about the emails sent from their domain. This not only helps in monitoring the usage of the domain but also identifies unauthorized use, such as phishing attempts, which can be crucial for maintaining trust in email communications.

With DMARC implemented, senders receive feedback on the legitimacy of their emails, enabling them to enhance their email practices and improve security measures. This level of insight can guide organizations in refining their email authentication strategies and helps ensure that legitimate emails reach their intended recipients while fraudulent messages are blocked or flagged.

In comparison, the other options do not align closely with the primary functions and advantages provided by DMARC. Increased storage for emails and faster email delivery focus on different aspects of email management rather than authentication and security. Improved image handling in emails pertains to presentation rather than the functionality of authentication protocols like DMARC, which is primarily concerned with verification of sender legitimacy and reporting mechanisms.
