HENNGE Email DLP

現在、HENNGE Email DLP からのメール配送の一部について Spamhaus のRBL等への誤登録により、送信先で受信拒否される事象を確認しております。

弊社システムチームにて調査を実施し、対象の RBL側へ解除の申請などをすすめております。

本事象にて受信が拒否された場合下記のようなエラーコードおよびキーワードが含まれたエラーメッセージが記載された、配信不能通知を受信することがございます。

■エラーコード 500番代(550, 553, 554 など) (メッセージ上には「said: 550 ...」のように記載されます)

■キーワード ・Spamhaus ・Rejected ・Blocked

このような配信不能通知を受け取った場合、該当のメールは宛先に配送されておりません。 お手数ではございますが時間をおいてから再度メールの再送信をお試し下さい。

ご迷惑をおかけしており恐れ入りますが、何卒よろしくお願いいたします。
