How to Blacklist an Email Sender in cPanel

To blacklist an email sender so that messages with their email address in the ‘From’ field are automatically filtered into the Junk folder:

  1. Sign in to your HostM hosting account’s cPanel.

    Your cPanel access details are listed on the hosting account’s Info page in the Client Lounge.

  2. Under the Email heading, click Spam Filters.

  3. Click Show Additional Configurations.

  4. Click Edit Spam Blacklist Settings.

  5. Click Add a new “blacklist_from” item.

  6. Enter the email address that you’d like to blacklist in the blank box that appears.

  7. Click Update Blacklist (blacklist_from) to save your settings.

Your new blacklist entry affects messages received after the entry is created. It does not affect existing emails from the sender that may already be in the Inbox.

You may manually move an existing email from the Inbox to the Junk folder where desired. Keep in mind that emails in the Junk and Trash folders that are over 30 days old are automatically removed by the system.
