SpamBox is an extremely accurate yet easy to use spam filter that seamlessly
plugs into Outlook. It detects almost any junk mail that it comes across and
it’s very easy to train it to recognize new spammer tricks. And once it’s initially
configured, it works silently behind the scenes to keep spam out of your way.

SpamBox uses Bayesian filtering to accurately determine whether a message is
spam or not. This is done by showing SpamBox a sample of both spam and non spam
messages. Statistical analysis is done on the messages and saved for future
use. When a new message comes in, SpamBox searches it for patterns that indicate
its spam probability. This method is extremely accurate and will even catch
obscure spammer tricks like misspelling suspicious words and embedding messages
in pictures and HTML.

SpamBox is very simple to configure and supports default settings that work very
nicely in most settings. There are settings to fine tune for accuracy as well
as to increase performance during training and scanning.
