Do not allow "fake email" for registration

Question

We have a registration process where users can register with their email address. We do not want to allow to register with fake emails like 10minutemail, or equal. How can I implement that? Is there a blacklist for tose domains?

Answer 1

Here's a pretty comprehensive list of temporary/disposable email domains. So depending on how you're handling the form submission, you might check against a list like that before processing the info for registration.

There are also some email validation APIs you might want to check out.

Answer 2

You can add an email confirmation to the registration process. If you are worried about fake temporary emails, you can add a delay before confirmation email is sent.
