Another idea about filtering spam. To reduce the occurrence of false positives, search in the body of a message for certain words. If you find those words, declare the message to be non-spam. The key words could include names of your company's products, names of family members, organizations that you belong to, and so on. A good idea would be to include one or more unique words in your signature, and search for those words in incoming messages. If you find those words in an incoming message, then it is likely that that message is a reply to a message that you sent.
