メールを送信できますが、メールを受信できません（Postfix付きCentOS）。

フォローするこれチュートリアルと電子メールクライアントで設定できるメールアカウントを作成できます。

問題は受信トレイにメッセージはまったく受信されませんが、完全に送信できます。。 Gmailから新しく作成したアカウントに電子メールを送信しようとしましたが、下の画像に示すようにGmailに自動的に送信されるエラーメッセージを受け取りました。

これは私の設定です/etc/postfix/main.cf。

返品、実行中のCentOSサーバーには、mail.dougb3ney.comのAレコードがあります。

修正する: メッセージは受信トレイにはまだ表示されませんが、送信者は失敗したメッセージを受信しません。

まだ奇妙なエラーが発生します/var/log/maillog
