I spent most of yesterday playing with SpamAssassin, ending up installing my own copy instead of using Dreamhost’s instance. It seems to be working, more or less, but will take some time to train. If you send me an email sometime within the next month, and I don’t reply within a few days (and your message warranted a response), try to send it to me again. Or contact me through other means.
(I will be checking my “Spam of Death” folder for false-positives and correcting them, but you never know.)
