I’ve given up on spam detectors. Although Cloudmark was hitting 90-95% accuracy, the sheer volume of spam it missed (with 200 mails a day, 125 spam and therefore 12-15 spam) was causing me pain coupled with the fact that it was slow to sort through the incoming mail. Rather than change my mail address which looked to the be obvious thing to do (but probably only useful in the short term), I’ve switched outlook to bounce anything but “trusted” senders – so if you don’t get mail from me after you’ve sent me one, you’re probably sitting in my spam box waiting for me to trawl through occasionally and sift out people I really should write to. Sorry.
