laravel 5.3中的电子邮件验证

Question

我想检查用户提供的电子邮件是否有效。为了做到这一点，我修改了寄存器用户文件的寄存器方法。这是我的代码

 public function register(Request $request)
    {
        $this->validator($request->all())->validate();
        Mail::to($request->email)->send(new RegistrationConfirmationMail($request->email));
        if( count(Mail::failures()) > 0 ) {
            return redirect('/register')
                ->withInput($request->only('email','name','address','district','gender','mobile'))
                ->withErrors(['invalid_email', 'Your email does not exist. Provide another email']);

        }

        event(new Registered($user = $this->create($request->all())));
        $this->registered($user);
        $this->guard()->login($user);

        return $this->registered($request, $user)
            ?: redirect($this->redirectPath());
    }  

但是这段代码没有将我重定向到注册页面，而是注册用户并登录了他。怎么解决这个？
