It's entirely likely that a spammer would try to get a hold of a key due to its value or that someone you've done business with would share keys with a "business" partner . But ideally you'd authorize each sender with a unique key (or some sort of pair/combination). So that 1) you can tell who the spammer sourced the key from and 2) you can revoke the compromised key's authorization to send you subsequent email messages.I suppose the obvious question is: What's to stop a spammer from putting a totally legitimate key into their spam?
There's probably some way to generate authorization such that each sender gets a unique key or a generic base is in some way salted or combined with information from the individual you're giving your authorization to such that the result is both unique and identifiable.
