Wouldn't it be utterly badass if, upon encountering a message that scored, say, a 15 or above in SpamAssassin, your MTA could not only tag it with a spam header but could, optionally, fling it back across the internet, with a flaming bag of soggy dogcrap attached, into the face of the sender? Maybe in version 3.0.

“In My Egotistical Opinion, most people’s C programs should be indented
six feet downward and covered with dirt.”
