This tool was not produced to help spammers find even more open relays to exploit. It was produced for ISP's to monitor their broadband customers and to close any down that are running open relays.
It is very hard to keep track of thousands of Leased Line and ADSL customers who are running servers with open relays, so I felt that there was an opening for a tool such as this.
Is it not better to inform customers of their open relays than to allow spammers to use them undetected?
Why, why?
Why did you produce this? Why are you giving yet more tools to spammers?
