リレーホストによる発信速度制限

リレーホストによる発信速度制限

Postfixでドメイン固有の速度制限を取得するには?

リレーホストの後にPostfixサーバーがあります。リレーホストはMS Exchangeブリッジです。リレーは調整を実行せず、早すぎる送信について文句を言わない。

速度制限を有効にしましたが、各ドメインの各電子メールの間に1秒の遅延ではなく、各電子メールの間に1秒の遅延が導入されました。

私の期待は、gmail.com、att.net、およびyahoo.comのいずれかのアドレス(以下のログフラグメントを参照)が同じ秒以内に送信され、次のyahoo.comアドレスが次の見積もりで送信されることです。

以下はログの一部です。
