Traditional spam filters require continual updating to keep up with the ever-changing nature of spam.

More worryingly, spam filters guess whether or not a message is spam and cannot offer 100% accuracy. A "false positive" occurs when a filter guesses wrong. The result is that you miss an important, legitimate message. False positives remain an insurmountable problem for traditional spam filters. False positives can be costly and very embarrassing for you. As the volume of spam increases, filters are responding by making it harder for a legitimate mesage to get through and so the number of false positives increases.
