How to Blacklist email addresses 

Blacklisting an email address blocks messages from specific senders, preventing unwanted or spam emails from reaching your inbox. It’s a simple way to stop recurring junk mail or messages from domains you don’t trust.

Step 1. 

Log in to your Internic account, select “My Account” in the top right corner, then from the drop-down menu, click “Hosting Manager”.

Step 2. 

On the right hand side of your wanted package, click the button showing "Control Panel" this will open you to the hosting OS.

Step 3. 

Using the left-side menu, select "Mail".

Step 4. 

You will then see a list of your email addresses, on the most right hand side you will see the Security option. Underneath this, click "Settings" for the email address you would like to update.

Step 5. 

Here you are able to scroll to the bottom and see the option Blocklist. In the field next to it, you are able to input any email addresses you would like to block. Please be sure to:

• Only put ONE email address per line 
• Do not use ? or * as wildcard characters 
• Use @domain.tld for filtering a whole domain
• Use @tld to filter the complete TLD 

Once you have added the necessary information you are then able to click "Save".
