Put your Highrise Dropbox address in the BCC field automatically in Mail.app

Want to put your Highrise Dropbox address in the BCC field automatically in Mail.app?
Easy Automatic Highrise Dropbox in Apple Mail offers a hack that will make it so (requires messing with Terminal.app so "buyer beware"):

1. Open Terminal.app
2. $ defaults read com.apple.mail UserHeaders
3. If nothing shows up, you don’t currently have anything set and you should be golden to move to the next step.
4. $ defaults write com.apple.mail UserHeaders '{"BCC" = "dropbox@YOURDROP.highrisehq.com"; }'
5. Restart Mail.app

That’s it. From now on your email should be automatically BCC’d to your dropbox address and you should get a warm fuzzy feeling inside.
