lugh.ch is originating from a local Linux users group. They keep the blacklist as an additional SPAM-prevention layer for their mail system but they have also opened it up for public use.
Delisting is not possible but the IP's will get delisted after 4 days.
Is the information on our site wrong or incomplete? You don't want us to monitor your blacklist? Or do you operate a similar blacklist? We would like to hear from you!
