title: Could not Reset password using Laravel 5.3.4
body: <p>I'm new to php/laravel tech.
  My .env file contains following configuration[1];</p>
  
  <p>When I try to reset the password, It says, password link has been sent, But I haven't received any emails.
  What I'm doing wrong here?</p>
  
  <p>p.s: I'm providing null for  MAIL_ENCRYPTION/ MAIL_USERNAME, due to one issue I faced.(Swift_TransportException Failed to authenticate on SMTP server with username "abc@abc.com" using 2 possible authenticators)</p>

  MAIL_ENCRYPTION=null
  MAIL_USERNAME=null
  MAIL_PASSWORD=null
  MAIL_FROM_ADDRESS=abc@abc.com
  MAIL_FROM_NAME="Administrator"
