History for safe.dnsbl.sorbs.net (Last 10 Days)

We keep some statistics on blacklists. Below is the graph for safe.dnsbl.sorbs.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.
