Wouldn't backscatter spamming already currently work the same way with messages where the return path address does not align, or with completely unauthenticated messages? > • I agree with others that SPF is much easier to set up than DKIM, as no > changes need to happen to the sending infrastructure itself. This makes DMARC > adoption much easier. I'm with Brandon on this: Only setting up SPF and DMARC without DKIM will just extend someones pain. Authentication will fail under various circumstances: Messages will get rejected, forwardings will break and messages with a null sender won't arrive anymore anyway. If SPF gives anyone the impression that they can enforce DMARC without setting up DKIM then this wouldn't be an advantage in my opinion, but a reason to deprecate SPF. -- 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.
