What is a False Positive?

Since no anti-spam software will ever be absolutely perfect, there is always a risk that the spam filter will classify a good message as spam. A False Positive is when the filter falsely identifies a good message as spam. For this reason, virtually no spam filter will actually delete mail – it will move it to a folder so you can glance through it and delete it manually. With all of the lawsuit happy people, no company could take the risk of keeping you from getting something sent to you – it would be like having the mailman decide which envelopes you really might want.
