| | Security Pipeline | Yet Another POPfile Review |
 | | POPfile does a statistical analysis on those messages to determine patterns of word usage, and, after a short time, the software starts classifying incoming messages into the appropriate bucket, automatically sorting those messages based on their similarity to messages that are already in each bucket. |
 | | POPfile is an e-mail proxy, meaning (as Scot explains it): "It requires you to reconfigure your email program (there's a wizard that does this for you, and it works very well) to redirect mail through a generic local port so that POPFile can literally filter your mail before it gets to your email package. |
 | | That means that POPfile bypasses the normal statistical analysis for that bucket; POPfile simply looks for specific text in the sender, recipient, cc or subject headers and classifies messages based on the presence or absence of that text. |
