Mark Perkel, a long-time expert in junk email filtering and operator of Ctyme.com, has announced he is battling stage 4 lung cancer. Perkel is seeking a successor to train and take over his specialized spam filtering business, which serves many non-profits and the EFF. The discussion also touches on the "extortionate" practices of some email security organizations like Spamhaus, contrasting them with Perkel's principled approach to email management.
