In regards to this and the habeas blacklist, this blacklist has been useful.
SpamAssassin checks all emails that contain the habeas headers against the
habeas blacklist and gives them 18 points.  So, most spams containing the
headers get an additional 18 points rather than being whitelisted.

Remember to report any spam with habeas headers to http://www.habeas.com/report/
for their blacklist and legal action.
