47.2.1 Real-Time Blacklists

Many organizations, such as Mail Abuse Prevention System (MAPS*) and SpamCop*, provide lists
of IP addresses that are known to be open relay hosts or spam hosts. If you want to use free blacklist
services such as these, or if you subscribe to fee-based services, you can define the blacklist
addresses for these services. The Internet Agent then uses the defined services to ensure that no
messages are received from blacklisted hosts. The following sections provide information to help
you define blacklist addresses and, if necessary, override a host address included in a blacklist.
