- Interface is extremely poor. <p>- You never know what is doing. <p>- Reports are never sent to the email it requires. <p>- Doesn't allow specifying the type of open relay test you want to perform. <p>- You don't know what test of open relay is performing. <p>- You don't even know if it performing any test at all... the program doesn't do anything but staying on the screen. <p>- It is just a waste of time.
