Enabling the settings

Open any form and click on the edit form. Choose the question type as Email and click on advanced settings. There you will see a toggle Define allowed/restricted email format responses, as shown in the screenshot below.

After enabling the settings, enter the email domain you want to block, e.g. spam.com, and toggle to Deny. Next, save the form and try it out in live mode. This is how the form will display an error message if the user attempts to type a blocked email.

Click on the + Add New Format button and toggle the settings as per your preferences to add as many email domains as you like.
