Are Country blacklists working?


Recommended Posts

So it is listed on the DNS list, which I personally use to filter mail.  Aside from that, I wasn't aware China had a BL.  To be honest, I'd love nothing more than to block all Chinese and Korean IPs.. but that will likely never happen.


Brandon, Do you use spamcop webmail??? Do you have all the DNSBL's selected?

Here is the list spamcop allows us to choose from.

LOL now I feel stupid. I have SCMail and have all the lists selected, but I forgot Cluecentral was for China. I should probably take another look [at] the BLs and make sure I have them all selected.

I do have to say though that it confuses ME, then, how so much spam can come from Chinese IPs, yet not hit those lists. I also find that the thousand or port scans I get a night are from Chinese IPs.
