Securing Email with Cisco Email Security Appliance (SESA) — Question 74

A Cisco ESA administrator was notified that a user was not receiving emails from a specific domain. After reviewing the mail logs, the sender had a negative sender-based reputation score.

What should the administrator do to allow inbound email from that specific domain?

Answer options

• A. Create a new inbound mail policy with a message filter that overrides Talos.
• B. Ask the user to add the sender to the email application’s allow list.
• C. Modify the firewall to allow emails from the domain.
• D. Add the domain into the allow list.

Correct answer: D

Explanation

The correct action is to add the domain into the allow list, which will explicitly permit emails from that domain despite the negative reputation score. Creating a new policy or modifying the firewall might not specifically address the sender's reputation issue, and asking the user to add the sender to their application’s allow list does not resolve the server-side restrictions.
