Comcast Gets Tough on Spam

WeakGeek writes "The Washington Post is reporting that Comcast, the nation's largest broadband ISP, has started blocking port 25 to reduce Spam. Jeanne Russo said Comcast is not blocking port 25 for all its users because it does not want to remove the option for legitimate customers who process their own e-mail. So the company is monitoring traffic and picking out machines that look suspicious. By blocking port 25, they say they cut Spam by 20% last week." ZDnet has another article, with a nice statistic: Comcast generates 800 million email messages/day, but only about 100 million of those are sent through Comcast's SMTP servers.

Re:Why not pass through their mail servers?

As I am the end user, I would prefer not to have control taken away. However, I don't see blocking mail coming directly from home users' systems as taking away control, your system is still your system, unless their email server is hosed, which it sounds like it is. You said it was slow, which is not very specific, which is the reason I qualified my statements in my previous comment to the point where your comment was unnecessary and this one is redundant.

In the end, the ISP has control over every packet leaving your network anyway.
