But this is really easy to work around. Isn't the Soth Korea arguing that all mail relays should block port 25, not just those on residential networks?

- mike-cardwell 15y agoI haven't seen them say that anywhere. If they block port 25 everywhere, then they simply prevent the ability to send or receive email within South Korea. That's clearly not their plan. The port 25 block is designed to force compromised systems to route email via controlled boxes. The fact that you can route email via controlled boxes doesn't mean you've worked around the block, it means you've been forced to do exactly what the intention was.
- alexchamberlain 15y agoMaybe I've misunderstood something. I wonder how much spam is sent via compromised residential systems and how much is sent via less than perfect commercial systems?
- mike-cardwell 15y agoThe vast majority is from botnets, which compromise mostly of compromised residential systems. http://www.theblaze.com/stories/email-spam-down-82-percent-since-july-2010/ http://www.theblaze.com/stories/email-spam-down-82-percent-s...
