Hi, I have been slowly working on implementing a spam filter that analyzes the title of the email and uses a Rabin-Karp hashing algorithm to classify the email.
I put up a summary of the work here: http://www.michaelpapet.com/blog/title-only-spam-detection-research-1 I'd like some opinions from more experienced email admins so I can better develop the detection process. My writing is bad, so let me know if somethings aren't clear. At this very early stage, it looks promising... Thanks for the great project. mpapet
