Greylisting is an email filtering method used to reduce spam by temporarily rejecting emails from unknown or untrusted sources. When an email is sent, the greylisting system initially rejects it. Legitimate servers will attempt to resend the email after a short delay, while spam servers often do not. This method helps to block a significant portion of spam emails.
Understanding Greylisting
Greylisting temporarily rejects emails from unfamiliar sources. Legitimate servers will resend the email, while many spam servers won’t, effectively reducing spam.
Accessing the Greylisting Configuration
To begin configuring Greylisting, access the relevant section in cPanel.
Step 1: Log In to cPanel
Home > Email > Configure Greylisting
First, log in to your cPanel account. Navigate to the Email section and click on Configure Greylisting.
Enabling Greylisting
Once in the Greylisting section, you can enable this feature for your email accounts.
Step 1: Enable Greylisting
Configure Greylisting > Enable
In the Greylisting configuration, toggle the switch to enable Greylisting for your domain. This will activate the filtering method for all incoming emails.
Managing Greylisting Settings
After enabling Greylisting, you can customize its settings according to your preferences.
Step 1: Adjust the Greylisting Delay
Configure Greylisting > Adjust Delay
Set the delay period during which emails are temporarily rejected. This period is typically short enough to avoid significant delays in legitimate email delivery.
Step 2: Whitelisting Trusted Sources
Configure Greylisting > Manage Whitelist
Add trusted IP addresses or domains to the whitelist to bypass Greylisting for emails from these sources, ensuring they are delivered without delay.
By following these steps, you can effectively configure and manage Greylisting in cPanel, enhancing your email security by filtering out spam and other unwanted messages.
