And you block a lot of legitimate email too. In my server, my policy is to reject mail from hosts which are blocking me. This way, the sender recives a bounce with a 550 explaining that their ISP is blocking legitimate email from us. A lot of customers are not even aware of the fact that their ISP is blocking legitimate email at their backs. I have been able to white list my server in a number servers without moving a finger, just angry users calling customer service.
