Per-User Spam Weighting

Users may easily adjust their own spam settings to find out what works best for them; or users can simply accept the default settings selected by their System Administrator. This setting gives each spam check a relative value or 'weight' to be used when determining whether a given message is spam. This type of control allows users to tailor their mail to make sure that the mail they want gets through; and the mail that they don't want stays out.
