Installation:
composer require marcel-strahl/temporary-email-validator
In versions from 5.3+ you don't need the following step, because we load our package with Discover in Laravel. Add the ServiceProvider to config/app.php
MarcelStrahl\TemporaryValidator\TemporaryValidatorServiceProvider::class,
Add the rule (it's the rule with the name not_temporary_email) like any other rule in Laravel to the validator where you want to use it
$rules = ['required|email|not_temporary_email'];
Hint:
I am not the creator of the "Temporary Email Detection" but have changed the following package into a Laravel Validator rule!
Main Package
