title: Laravel 5 - Sending notification via Mail shows HTML source instead of HTML
body: <p>I'm sending a user - registered confirmation link email after signup.</p>
  
  <p>When i open that mail with my desktop client, all shows very well. When i open that mail with my Android phone client called "Mail" (version 10) it shows the HTML tags and every line of HTML source code instead of rendered HTML.</p>
  
  <p>What am i doing wrong? This is the <code>toMail</code> method from the notification:</p>
  
  <pre><code>public function toMail() {
      $subject = trans('mail.registration_confirmation');
  
      return (new MailMessage)
          -&gt;subject($subject)
          -&gt;greeting($this-&gt;registeredUser-&gt;greeting())
          -&gt;line(trans('app.thank_you_for_registering', ['app' =&gt; settings('app_name')]))
          -&gt;line(trans('app.confirm_email_on_link_below'))
          -&gt;action(trans('app.confirm_email'), route('register.confirm-email', $this-&gt;token))
          -&gt;line(trans('app.confirm_email_call_to_action'))
          -&gt;line("Just another line");
  }
  </code></pre>
