title: Laravel global send to address for testing
body: <p>I know how to set a global 'from' address in Laravel's mailer but I need to set a global 'to' address.</p>
  
  <p>I want to see the output of the emails but not send them to the actual user just yet.</p>
  
  <p>Swiftmailer has a delivery_address setting which does this but I can't seem to find this in Laravel's config.</p>
