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. :-) ]
