Try changing the MAIL_ENCRYPTION to TLS or the MAIL_PORT to 25 or 465

i changed my the port to 25 and the encryption to null it worked but for only one email and the other emails not working. it sends only to a specific email even i am making it dynamic:

// mail $user = User::find($request->user_id);

    $email = $user->email;


    Mail::send('site.pages.messageDraft', ['order'  => $order, 'user' => $user],
        function($message) use ($email) {
            $message->from('[email protected]', 'BuyOnline');
            $message->to($email)->subject('New Order');
        });

    return ['status' => 'success'];
