This work of one Bill Shackelford is documented at this page of his web site.

My Spamtrap monitors an email address I created specifically to lure in spam. I do not use this email address for any other communication. I post this email address on websites and online bulletin boards that cause it to be harvested by spambots and then to start receiving spam ... When a new spam email is detected by my installation, it automatically prints it out. The printed email slides down a track into the shredder that analyzes it.
