Comcast Port 25 Blocks Result In Less Spam

Posted by timothy on from the choke-it-off dept.

Dozix007 writes "Ars Technica reports that: 'After Comcast finally owned up to the massive amounts of spam coming from their network, they decided to identify spammers and zombie relays on their network and block port 25 traffic from those IP addresses. Comcast's efforts are starting to pay off. They announced the amount of spam from their network has dropped 35 percent since they began port blocking and traffic estimates from SenderBase seem to confirm the claims. Spam coming from Comcast subscribers who were formerly on AT&T networks also seems to have decreased'."

    I'm on Comcasts network, and I haven't had any problems sending email, and I'm not using their email servers. This seems to be an isolated policy perhaps?

    Hmm... Spam is high in carbs, isn't it?. Are you on the Atkins Diet by chance? But seriously, to what do you attribute the drop?
