Read this jaw dropping article about how someone "patented" what has been done by procmail for many, many years.
http://informationweek.com/news/showArticle.jhtml?articleID=201802746 ``The method and system detailed in the patent describes a way "for automatically interpreting an electronic message including the steps of (a) receiving an electronic message from a source; (b) interpreting the electronic message using a rule base and case base knowledge engine; and (c) retrieving one or more predetermined responses corresponding to the interpretation of the electronic message from a repository for automatic delivery to the source."'' Let's see, spamassassin interprets electronics messages and uses a rule base to retrieve predetermined responses such as "spam" or "ham". I do not know if I should laugh or cry, any suggestions? i
