This video illustrates a simplified version of how connection filtering works compared to content filtering in the world of anti spam services. The first scene is set in a content filtering environment where a spam filter examines the data part of an email to determine if it's a spam mail or not. This results in a heavy workload and a disgruntled end user. The second half shows the workings of an anti spam service using connection filtering. The service determines whether the delivering server is legitimate or not, and either accepts the data portion then or drops the connection.
This looks great!
