This guide helps in understanding how to add a Null MX to Plesk. Adding a Null MX record to Plesk prevents email from being delivered to a domain by effectively disabling its mail services.
Mail Exchange (MX) records specify the servers to which emails for a domain should be routed. This record is essential for receiving email for your domain.
Let us add a Null MX:
- Log in to Plesk.
- Choose the domain that you want to stop receiving emails from.
Note: Choose the main domain if you want to block all subdomains. - Navigate to Hosting & DNS> DNS.
- Create a new DNS record with the type set to MX.
- You can leave the host entry blank for the current domain only, specify it explicitly to a subdomain, or set it to * if you want to block for all subdomains.
Note: Verify that the mail exchange server is empty and that the priority is set to 0. - Verify if the domain’s other MX records have been removed.
- To save the DNS changes, click “Update”.
- Remote mail servers should cease sending emails to the designated domain as soon as they notice the altered DNS.
In this manner, adding a Null MX record to Plesk effectively disables email services for your domain, preventing any emails from being delivered.
