NSE 6 – FortiMail 7.2 — Question 27

A FortiMail administrator is investigating a sudden increase in DSNs being delivered to their protected domain. After searching the logs, the administrator identifies that the DSNs were not generated because of any outbound email sent from their organization.
Which FortiMail antispam technique can the administrator use to prevent this scenario?

Answer options

• A. FortiGuard IP Reputation
• B. Spoofed header detection
• C. Spam outbreak protection
• D. Bounce address tag validation

Correct answer: D

Explanation

The correct answer is D, as Bounce address tag validation helps to verify that bounce messages are legitimate and not generated by spammers. The other options, while useful for different scenarios, do not specifically target the issue of preventing unwanted DSNs from being delivered to the domain.
