MX (Mail Exchange) records determine which mail servers handle email for your domain. Updating these records is essential when configuring custom email services such as Google Workspace (formerly G Suite), Microsoft 365, or other third-party providers. This guide explains how to modify MX records in cPanel.

What Are MX Records?

MX records (Mail Exchange records) control how email is routed for a domain. Each record includes:

• Priority – A number that indicates delivery preference. Lower values have higher priority.

• Destination – The hostname of the mail server that should receive the email.

How to Modify MX Records in cPanel

1. Log in to cPanel

• Open your browser and go to your cPanel login page (e.g. https://yourdomain.com/cpanel).

• Enter your username and password, then click Log in.

2. Open the Zone Editor

• In the cPanel dashboard, scroll to the Domains section.

• Click Zone Editor.

3. Locate the Domain

• In the Zone Editor, find the domain you want to modify.

• Click Manage next to the domain name.

4. Edit an Existing MX Record

6. Remove Unused MX Records

• To prevent conflicts, delete old or unnecessary records by clicking Delete next to the corresponding entry.

Verify Your Changes

Changes to MX records may take a few minutes to 24 hours to propagate, depending on DNS caching.
You can use tools like MXToolbox to check if your updated MX records are active and configured correctly.
