Configuring the Real-time Blacklist
Blacklist providers are organizations that collect IP addresses of verified open SMTP relays that
might be used by spammers as media for sending spam. These known spam relays are compiled by
blacklist providers and are made available to the public in the form of real-time blacklists (RBLs).
By accessing these RBLs, the STM can block spam originating from known spam sources.
