How to Block Emails by Country or Domain

With the latest release in cPanel, a new feature has been introduced to block emails by country or domain. There are two interfaces you can use to block email messages:

1) Filter Incoming Emails by Country

1) Log in to WHM as the root user and navigate to the ‘Email’ section.

2) Select the ‘Filter Incoming Emails by Country’ option.

Using this interface, you can filter your incoming emails based on region or country. By utilizing this interface, you have the ability to allow only mail from a specific country, effectively blocking emails from other countries.

To block emails from a specific country, you can disable the Allowed toggle for that country in the Nations table. To allow or block all countries, follow the steps below:

1) Select the ‘Select All’ checkbox at the top left of the interface.

2) Click ‘Allow Selected’ to allow all selected countries.

3) Alternatively, you can click ‘Block Selected’ to block them.

2) Filter Incoming Emails by Domain

1) Log in to WHM as the root user and navigate to the ‘Email’ section.

2) Select the ‘Filter Incoming Emails by Domain’ option.

Using this interface, you can block emails from a specific domain. When you specify a domain in this interface, your server will reject email messages where the ‘From’ address matches a blocked domain. This feature is useful for blocking emails from a domain that exclusively sends spam.

To block a domain, follow these steps:

1) Add the domain details in the ‘Blocked Domains’ text box. For multiple domains, use a new line for each domain.

2) Click ‘Save’.

To block all emails from subdomains of a specific domain, prefix the domain name with an asterisk (*) in the ‘Blocked Domains’ text box. This wildcard character will reject any emails from subdomains as well. For example, if you enter ‘*.test.com’ in the ‘Blocked Domains’ text box, your server will reject any email messages from subdomains such as abc.test.com, xyz.test.com, and so on.
