Why a wrong email is accepted even after using laravel validator? 
$validator = Validator::make($request->all(), [            
            'email' => 'required|email|unique:users',
        ]);
        if ($validator->fails()) {
            return ResponseBuilder::error($validator->errors()->first(), '422');
        }
This set of code accepts "@ot.com". I don't think this should be accepted.
