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.  It's here:

[ Or any URL that doesn't refer to a valid document, for that  
matter.  :-) ]
