Activation of Greylisting in the WHM administration panel

Introduction

• In this tutorial, we will show the necessary steps to activate the greylisting option in WHM.
• Greylisting protects email users against spam. When enabled, the email server will temporarily reject any email from a sender that the server does not recognize. If the email is legitimate, the originating server will try again after a delay. After a sufficient amount of time has passed, the server will accept the email.

Requirements

• Access to the WHM administration panel.

Steps

• After we log in to the WHM administration panel at https://numedomeniu.tld/whm, we will go to Email Address and click on Email Address.

 

• In the next page, we will click on Greylisting.

• To activate, we will click on the button in the previous image.

• After greylisting has been activated, we have access to its configuration settings.
• Configuration settings come with default values that can be modified by us later.
• In the next tab Trusted Hosts we can add IP addresses of senders that do not already exist in Common Mail Providers.

• The Common mail providers is a predefined list of senders whose emails will not be delayed in being received by the recipient's server.

• In the Reports page, we will be able to see the current status of the triplets in the system. A triplet consists of the sender's IP address, the sender's email address, and the recipient's email address.
