Lists any kind of Backscatterer which we see at the UCEPROTECT-Network. You can simply use this list via DNS at ips.backscatterer.org for scoring or rejecting misdirected bounces and misdirected autoresponders and sender callouts from abusive systems.
Listing Policy is quite simple: Every IP which backscatters (Sending misdirected bounces or misdirected autoresponders or sender callouts) will be listed the next 4 weeks.
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 ips.backscatterer.org. 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.
