I've been waiting for this forever. Filter email from Russia or China in GMail!
- Click "Create Filter" located at the top of your Inbox
- In the "Has the words:" field, enter: lang:Russian
- Select "Delete it" within the Action List, and (if you have existing Russian Spam) select: "Apply Filter to Conversations below"
- Click "Create Filter"
Of course, if you expect to receive legitimate email in Russian or Chinese, don't do this. :) But I'd say 80% of my spam is in Chinese...
