April 13, 2022 / cPanel & WHM

This tutorial will show you how to enable the Greylisting in WHM. Greylisting is an e-mail spam screening technique. With a “temporary rejected” answer, a Greylisted Mail Transfer Agent (MTA) rejects a malicious email.

Let’s take a look at how to do it:

1. Log in to WHM.


2. Select the “Email” section from the left-hand side of the screen and click on the “Greylisting” option.


3. From here you can enable or disable the option.

4. Enable the option.

5. After enabling you will see the following four categories:

a. Configuration setting

b. Trusted Hosts

c. Common Mail Providers

d. Reports

5. You can also bypass the Greylisting for Hosts with Valid SPF Records by ticking the box as shown in the image.

8. The Greylist Report shows the current state of the system’s triplets. A triplet is made up of the sender’s IP address, the recipient’s From address, and the recipient’s To address.
