python - Django-paypal がシグナルを受信しない

Question

プロジェクトで単純な Paypal 支払いを作成しようとしていますが、それが機能するかどうかを確認してから、よりカスタム化します。問題は、期待どおりに機能しないことです。(サンドボックスを使用して) 支払いを行うと、myemail-buyer@gmail.com は正常に送金されますが、myemail-facilitator には通知がありません (ただし、お金を受け取りました)。さらに、シグナルが受信されておらずPaypal IPNS、 Django-admin に行がありませんPaypal IPNs。

おそらく多くのことが考えられますが、私はdjango-paypalが初めてなので、何が問題なのかわかりません。

開発サーバーを使用していますが、外部からアクセスできます。
