Challenge/Response.  Basically, if your mail system receives mail from
someone it doesn't know about, it holds on to it, sends a challenge to
the alleged sender and doesn't deliver it until it receives a suitable
response.  If no response is recived within a time limit, the mail is
discarded.

It's the lazy man's solution to spam, shifting the problem out of your
inbox into those of other people.
