In that case I think you're out of luck. All web-based e-mail programs that I know of utilize HTTP for file transfers, making it difficult to block. Unless there is a specific URL that is involved in the file attachment sequence, I do know of a way to block just that function.

But I want to restrict uploading also. For example user can open yahoo mail but not upload any data on mail.
