I hope you don't mind my breaking into this thread, but I have a question regarding SA helpers. My mail setup is sendmail with spamassassin, and I'm using SARE rules and bayes. Ours is a small shop (mail vol. about 1000 msgs./day). Right now, I get virtually no FPs, and an occaisional FN. As we grow, I would expect that we'll be receiving more spam. What would Razor, Pyzor, and DCC do for me? Sorry for my ignorance. Dimitri
