Pointing 1and1 domain to an S3 bucket

I've registered my domain about a month ago (It's a .com, so I need to wait 60 days before being allowed to transfer the domain, which I will do as I'm fed up with 1and1's service)

I created an Amazon S3 bucket with my domain name: example.com and www.example.com.

All my Amazon S3 settings are in order, I've enabled website hosting, I have an index document...

In 1and1, I've set my redirect destination for example.com to my S3 bucket endpoint.

When I hit save: "Operation Failed, The redirect URL is invalid."

What am I doing wrong?
