Depending on what the user sets their hash key length to, they can make a sender of a message take varying amounts of time to break the key. For individuals, this might mean that it takes you 1 second or so longer to send a message; for spammers, 1 second * lots of people = too much time and effort. Which reduces the amount of spam. Has anyone thought about making this an RFC that extends the various mail protocols? Cem
