The Razor project looks interesting.  However, the site is poorly 
written, and I can't seem to find out how it actually works.

I am still interested in setting up a honeypot account on my server, 
then spreading this account all over the net so that the harvesters that 
have picked up my e-mail address will pick up the spamtrap address.  
Then, any e-mail received to this account will get canned.
