Hi Adam, Currently, App Engine does not allow applications to add or modify the user agent header, so I'm not sure there is something that can be from your application that will allow Yahoo! to accept the requests.
Your best bet is to contact Yahoo! when the re-enable posting to see if they can add the appropriate User Agent to their whitelist.
