title: Laravel 5.7 - Verification email is not sent
body: <p>I've upgraded my laravel instance from version 5.6 to version 5.7. Now I try to use the <a href="https://laravel.com/docs/5.7/verification" rel="noreferrer">built-in email verification from laravel</a>. </p>
  
  <p>My problem is that I don't get an email after successful registration when I use the "resend" function the email arrives. </p>
  
  <p>What is the problem?</p>
