More Information About Ibm Dns Blacklist

The IBM DNS Blacklist (Cobion) lists IP addresses that have been identified as spam sources. A positive listing can occur if several emails have been rated as spam by the Proventia Mail Security System or the Lotus Protector for Mail Security systems. This blacklist zone is part of the default configuration for both systems.
