Laravel 5.1 Resest Password

Hey guys i am facing iccuse at reset password in Laravel 5.1 My code works but i did'nt get any email . And also Mandrill don't show any email sent. But i receive email on user registration. Here is my code

public function getEmail(Request $request)
    {
        return view('Frontend.auth.password');
    }
    
    public function postEmail(Request $request)
    {
        $this->validate($request, ['email' => 'required|email']);
        $response = $this->passwords->sendResetLink($request->only('email'), function($m)
        {
            $m->subject($this->getEmailSubject());
        });

        switch ($response)
        {
            case PasswordBroker::RESET_LINK_SENT:
                $message = "Password recovery link has been send to your email address";
                Toastr::success($message, $title = null, $options = []);
                return redirect()->back();
            case PasswordBroker::INVALID_USER:
                return redirect()->back()->withErrors(['email' => trans($response)]);
        }
    }

    protected function getEmailSubject()
    {
        return isset($this->subject) ? $this->subject : 'Your Password Reset Link';
    }
    
    public function getReset($token = null, Request $request)
    {
        if (is_null($token))
        {
            throw new NotFoundHttpException;
        }
            $messages = "Create your new password";
            Toastr::info($messages, $title = null, $options = []);
            return view('Frontend.auth.reset')->with('token', $token);
    }

In Success case i recived the Message Password recovery link has been send to your email address

THis code works in Laravel 5 like a charm. but not sending email with 5.1 whats should i have to do. ?
