temporaryemailproviders.json / temporaryemailproviders.php

A collection of domain names used by disposable / temporary email providers. Useful if you want to block a big part of fake registrations on a website. Remember that this list will never be complete, and that black listing in this way is only a tool, not a complete solution.

Check if a domain matches this list with something like this:

if(isset($temporaryEmailProviders[$domain])) {
  doSomething();
}
