Found an article about measures Google is taking to block domains using suspicious unicode characters: http://threatpost.com/google-tweaks-gmail-to-help-limit-spam/107732 Mark Martinec mentioned I should open a ticket to make sure the idea for implementing this with SA doesn't get lost. Here's the thread: http://www.gossamer-threads.com/lists/spamassassin/users/186856
