The simplest case is to set up some email addresses on a website which point to a machine with no valid users, and then pay attention to any incoming mail and blacklist that traffic, ie, add the IP addresses of sending machines to a deny list like the access map, or feed the contents of such mail into SpamAssassin or other such tools which perform Bayesian text recognition. Recently I'd written a Python program to generate such pages to try and pollute spam databases, which also helps against critters who scan websites and then launch dictionary attacks against user accounts via SSH and so forth.
