  3. Bounce + DKIM

    Hi, We are currenty signing outgoing messages for specific domains with DKIM. The problem is that all bounce messages are not signed with DKIM. It is flooding our DMARC reports with PMG hostname as subdomain. Can we sign bounce messages with DKIM in any way? Or the only option is to create...

  7. [SOLVED] Multiple DKIM

  10. [SOLVED] DKIM Ändern des Selektors führt zu Neugenerierung des Private Keys

    Wenn der DKIM Selektor im GUI geändert wird, wird automatisch ein neuer Private Key /etc/pmg/dkim/selector.private generiert. Macht es nicht mehr Sinn zu prüfen ob /etc/pmg/dkim/selector.private existiert und das bestehende Zertifikat zu verwenden, sofern es existiert? (Verwendete PMG Version...
