Greylisting

Greylisting is a method of defending e-mail users against spam. A mail transfer agent (MTA) using greylisting will "temporarily reject" any email from a sender it does not recognize. If the mail is legitimate, the originating server will try again after a delay, and if sufficient time has elapsed, the email will be accepted.

Overview

This interface allows you to enable or disable Greylisting for each domain on your account. Greylisting defends email users against spam. When you enable Greylisting, the mail server will temporarily reject any email from a sender that the server does not recognize. If the email is legitimate, the server that sent it will try to send the email again after a delay. After a sufficient amount of time, the server will accept the email.

Hosting providers can configure your account’s Greylisting settings in WHM’s Greylisting interface (WHM>> Home >> Email >> Greylisting). You can view an email’s delivery status in cPanel’s Track Delivery interface (cPanel >> Home >> Email >> Track Delivery).

Enable or disable Greylisting

To enable or disable Greylisting on a domain, perform the following steps:

1. Locate the domain in the list, or enter the domain name in the Search text box.
2. Click on/off to enable or disable Greylisting.

Note:

 

 — To enable or disable Greylisting for all domains on your account, click the gear icon and select Enable All or Disable All.
