Re: How hard could this be?
The article addresses this - blocking port 25 would create a tech support nightmare with the possibly thousands of support calls from people who use smtp servers other than Comcast's, and would cost them a lot of money in support costs. Instead, according to the article they will monitor traffic and block the port only for subscribers who are sending out large volumes of email.
IMHO, this is a better solution than blocking the port for everyone. Just punish the bad folks, and leave those who behave alone.
It isn't that they have a large percentage of zombied users out there, it's actually quite a small percentage. The reason they are the "worst spammers" is simply because they are the largest ISP. A small percentage of a large number is still a large number. Blocking 25 would adversely affect a far larger percentage of subscribers than those who are spammers or zombie hosts.
So when you see that more spam is coming from Comcast IPs than, say, Verizon IPs, remember that Comcast has far more subscribers.
