This says that the yahoo user tries to send mail addressed to
b...@myapp.appspot.com, not to b...@example.org.

Your mail server is not configured to accept mail for that domain (but
DNS records point to it), so either:
- do not send mail to *...@myapp.appspot.com
- add myapp.appspot.com to $mydestination
