Angenommen, Sie haben eine POP3-E-Mail-Adresse in Ihrem Outlook oder anderen E-Mail-Clients gespeichert. Wenn Sie Ihre Benutzerinformationen in den Kontoeinstellungen geändert haben, können Sie den folgenden Anhang senden[email geschützt]E-Mail. Mein Mail-Dienst ist Postfix und ich habe alle Absender- und Empfängerbeschränkungen wie „reject_unlisted account“ oder „reject non-FQDN domains or hostname“ eingestellt, aber es hat nicht funktioniert! Wie beheben Sie dieses Problem in Ihren Enterprise-Mail-Diensten? Danke
Dies ist auch meine gesamte Konfiguration in main.cf:

Sie können die smtpd_reject_unlisted_senderPostFix-Konfigurationsanweisung verwenden. Diese isthier dokumentiert.
Beachten Sie, dass ich dies auch unbedingt protokollieren und die Person, die dies tut, sofort feuern lassen würde (es sei denn, es handelt sich natürlich um einen Tippfehler).
