メールサーバーが$ mydestinationを認識しません。なぜですか？

リモートメールサーバーから返されたエラーメッセージは次のとおりです。

ホストsmtp.terra.com.br [208.84.244.140]が言った：450 4.1.8：拒否された送信者アドレス：ドメインが見つかりません（MAIL FROMコマンドへの応答）

これは、そのドメインのDNSルックアップが失敗したため、[〜＃〜] from [〜＃〜]アドレスが拒否されたことを意味します。

問題のドメインはsales.intraこれは、私が見つけたDNSサーバーでは解決していないようです。

これを機能させるには、sales.intraパブリックDNSで解決するか、FROMアドレスを解決できるものに変更します。

機能した電子メールは、リモートサーバーではなくローカルに配信されました。ローカルサーバーはFROMアドレスをチェックして有効な作業ドメインがないか確認しないため、電子メールの処理を続行しました。
