The one thing missing from Google was a catch-all feature, where you could specify a default address so that email sent to anything@yourdomain.com would go to an address you specify. That was until I found out they'd actually added the feature a few months ago. You can set it up under the 'Domain Settings' tab by clicking the 'edit' button next to 'Advanced Settings'. There's a chance you'll just get loads of spam by setting up a catch all address, but if you have a surname like mine which people never spell right, they can spell it however they want and the email will still get to me.
