Description
In the battle against Spam, many mail server admins collect and distribute IP addresses of systems that send them Spam. However, distribution of these lists are traditionally limited to 2 methods.
* is periodically downloading this list from a source, usually a web server often causing massive load and slowness at the top of the hour.
* is a real-time lookup against an external provider (such as dns-rbls) so your response time is dependent on how fast they respond or timeout.
This talk discusses a 3rd solution: using BGP to distribute the IP addresses in a real-time manner.
