The author of the paper, Gordon Cormack, has a lot of experience in the area of information retrieval. It would be a good idea to carefully analyse his results and conclusions for ways to improve SpamAssassin and for approaches that we should ignore.
I've been very skeptical of the hand wavy approaches with little theoretical background or improper evaluation (e.g. Dobly and Bayesian chains). The results in Cormack's paper should warn us against blindly accepting "cool" ideas without taking the steps to ensure their validity. Lastly, the positive results speak for themselves. Kudos guys!
