The main goal of this list is to react fast to new SPAM sources and list them as soon as they are seen by kempt.net mail servers. The host will be removed after 24 hours of it's last message but will be relisted if it is found to be spamming again, and for a longer period of time.
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!
We keep some statistics on blacklists. Below is the graph for dnsbl.kempt.net. We test blacklists by asking them to respond to known IP's that are blacklisted and known IP's that can't be blacklisted. Not every blacklist has such IP's, we test them with what is possible. We keep if we get any response or error messages and the response duration. Lower response times are better. These statistics may be useful for email server administrators to pick which blacklist to use.
