OpenBSD spamd - greylisting and beyond is a presentation by BobBeck of the University of Alberta about the OpenBSD's spamd system, howspammers react to it and similar systems, how you can exploit this,and the University of Alberta's experiences with spamd, complete withinteresting numbers. I'm sadly jealous, as local feelings insure thatI'm not going to get to deploy this sort of technology any time soon.
