NSE 6 – FortiMail 5.3/5.4 — Question 7
A FortiMail administrator is investigating a sudden increase in DSNs being delivered to the protected domain for undeliverable email messages. After searching the logs, the administrator identifies that the DSNs were not generated as a result of any outbound email sent from the protected domain. Which FortiMail antispam technique can the administrator use to prevent this scenario? (Choose one.)
Answer options
- A. Bounce address tag validation
- B. Spam outbreak protection
- C. Spoofed header detection
- D. FortiGuard IP Reputation
Correct answer: B
Explanation
The correct answer is B, as Spam outbreak protection helps to mitigate the impact of sudden increases in spam or DSNs by identifying and blocking suspicious email patterns. The other options, while useful for different anti-spam measures, do not specifically address the issue of preventing excessive DSNs from undeliverable messages.
