But how do they 'know' it's spam?
It's a bit of a dark art and there is a fine balance between being
effective and being over enthusiastic and generating what are referred
to as false positives.

Part of the fine art is a list of addresses from which most spam
originates.

Or an application that learns how to recognise junk.
