| Re: Interesting quote in the linked article If you get a chance, maybe you could walk me through the logic, because it never makes sense to me.
A. ISP 1's customers, or malware bots on their machines, start sending spam to thousands of people through open relays on OTHER networks run by OTHER ISPs, for example ISP 2.
B. The complaints start building, and eventually ISP 2 says to ISP 1, "hey, your customer is a spammer -- stop it".
C. ISP 1, rather than deal with the naughty customer, AND rather than telling ISP 2 "close your frickin' relay", decides to globally block port 25 and stop Joe Worker from using JoesCompany's mail server to send mail!
What is the incentive, economic or otherwise, for ISP 1 to block port 25? A sense of responsibility to the Internet culture? What? It certainly doesn't reduce spam coming IN to ISP 1's customers.
