[Exim] Sorry, not directly Exim related, but interesting SPA…

From the slashdot posting:

"Paul Graham, the Lisp Guru is back with a great technique to fight
spam. It is based on trust matric, and he claims, only 5 out of 1000
spams got leaked out of this system with 0 false positives. Worth
looking at."
