Disallowing email addresses from specific domains?

The current feature only allows disallowing free email addresses.  However, we should be able to disallow emails from domains that fakemailgenerator use.  Have a look at www.fakemailgenerator.com

Unfortunately this is note possible, however I would recommend that you use Email validator in this case.

This will ensure that any email user uses they must have access to it to confirm with a code they will be sent for them to continue filling the form.
