Do you have logging enabled for your bucket?
If you do, you could check the logs to verify that a referer is getting logged along with those 403 Access Denied messages and that it's what you expect. If it isn't, then the problem isn't with the bucket configuration -- it's a question of why the referer isn't being sent by the browser.
If you don't have logging enabled, then enable logging.
Also an added benefit is that they can only access content from my domain rather than the supplementary s3bucket.amazon-east.amazonaws.com or something to that effect.
What makes you think this would be true?
