You've missed my point. The first priority is to stop spam, network tests are obviously necessary here. "Unnecessary, inefficient" traffic is a concern further down the list. On one server its bandwidth is negligible, but over thousands it would add up. It seems only logical not to run network tests when the local tests have done the job. Why ask a question when you already know the answer? Was just an idea that seemed fairly easy to implement... Cheers Scott
