Who can use the Blocklist

How the list is compiled
The reputation database is maintained by a dedicated team of specialists using various data from many sources to craft and maintain a large set of rules controlling an automated system that constantly analyses a large portion of the world’s email flow and the IP addresses in it. Most RBL listings occur automatically, although where necessary the LibraeSecure team will add or remove listings manually.
