Unfortunately I can’t say what Google or other third parties are planning to do in the future. At the moment DKIM signatures from a parent domain will pass DMARC checks as long as DKIM alignment is in relaxed mode. Independent of this I wouldn’t use r...@hostname.example.org as a sender address to external recipients. This doesn’t look professional, makes replying to those emails impossible and in case hostname.example.org doesn’t have a public IP address it might also increase the risk that those messages are treated as spam or rejected, because they are coming from an unresolvable domain. Many MTAs provide ways to rewrite sender addresses, so you could rewrite both MAIL FROM and header From to someth...@example.org before delivering the messages. This will resolve all questions about subdomains once and for all and doesn’t even require any changes to the applications which create the messages. — BR Oliver ________________________________ dmTECH GmbH Am dm-Platz 1, 76227 Karlsruhe * Postfach 10 02 34, 76232 Karlsruhe Telefon 0721 5592-2500 Telefax 0721 5592-2777 dmt...@dm.de<mailto:dmt...@dm.de> * www.dmTECH.de<http://www.dmtech.de> GmbH: Sitz Karlsruhe, Registergericht Mannheim, HRB 104927 Geschäftsführer: Christoph Werner, Martin Dallmeier, Roman Melcher ________________________________ Datenschutzrechtliche Informationen Wenn Sie mit uns in Kontakt treten, beispielsweise wenn Sie an unser ServiceCenter Fragen haben, bei uns einkaufen oder unser dialogicum in Karlsruhe besuchen, mit uns in einer geschäftlichen Verbindung stehen oder sich bei uns bewerben, verarbeiten wir personenbezogene Daten.
