It introduces a temporary failure for messages sent from new IP address. The idea is that a spammer MTA (example, a perl cgi script on a hacked account) will not try to resend a message when it encounters that error message, legitimate MTA's will retry to send the message a few minutes later. Once that happens, the IP of the MTA is whitelisted and no more delays are introduced for traffic coming from that system.

Now I'm starting to feel like my brain is really soggy. Isn't this what http://www.spamdyke.org/ implements (well, they spell it graylist, but that's just amatter of being born on different sides of the Pond, isn't it)?

yes they both implement greylisting/graylisting. Both spellings are acceptable here too :P
