How to Disable Greylisting for cPanel Email

Greylisting is a technique used by mail servers to block spam by temporarily rejecting emails from unfamiliar senders. The concept is that most spammers will not attempt to resend the email, whereas legitimate senders are likely to do so. While greylisting can help stop spam, it can also delay email delivery, which can be annoying, especially for legitimate emails from new or unknown senders. In that case, you can disable greylisting for cPanel email.

In this article, we’ll explain the process of disabling greylisting for cPanel email, which can help improve email delivery speed and avoid unnecessary delays.

What is Greylisting?

When an email is sent to a server with greylisting enabled, the server temporarily rejects it and waits for the sending server to try sending the email again after a short delay, usually a few minutes. The idea is that most spammers won’t bother to resend the email, but legitimate senders will. This practice helps us block spam.

It’s important to note that greylisting can cause delays for emails from new or legitimate senders. This is especially true if the senders are not set up to automatically resend emails after a failure.
