Once again, I’m glad to be using an ISP that’s willing to take some steps to combat spam and systems abuse. Sonic.net just announced that they will be firewalling any system using high speed DSL. By default, they will be blocking common exploitable ports and port 25. I’ll have to look at the list and see what else qualifies.
Sonic is also offering complete firewalling, which I assume means you have to enable ports on an individual basis, and just firewalling port 25. I think this is tremendous service to offer customers. For the people out there who have the technical skills to run their own mail servers, Sonic offers static IP addresses with no firewalling, which is what I’m opting for. It’s going to take actions like this from ISP’s everywhere to stem the tide of spam.
I’m very glad to see Sonic take these steps to protect their users, and I hope other ISP’s take note. As one of the largest independent (largest?) ISP’s, I hope Sonic is a group the corporate ISP’s are willing to learn from. Are you listening AOL?
