Example 6: Headers reporting results from multiple MTAs in different ADMDs

In this example we see multi-tiered authentication with an extended trust boundary.

例6: 異なったADMD内の複数のMTAからの結果を報告しているヘッダ

この例では、拡張された信頼の境界における複数段階の認証が行われている。

The message was sent from someone at example.com’s New York office (newyork.example.com) to a mailing list managed at an intermediary. The message was signed at the origin using [DKIM].

メッセージは、example.comのニューヨークオフィス(newyork.example.com)の誰かから中間で管理されているメーリングリストに送られた。メッセージは送信元で[DKIM]を使って署名された。
