False negatives[edit]

I disagree that context filtering has a low false negative (i.e. email incorrectly labelled as non-spam) rate: this rate is very high as, for instance, there is no way context filtering can detect spam sent from legitimate domains such as Hotmail or GMail. 62.56.68.149 (talk) 20:07, 6 October 2008 (UTC)[reply]
