As a non-native English speaker I don’t want to argue about the definition of „policy“. What I meant by the term policy is a statement that includes an action, comparable to a rule of a firewall: If condition X is true then perform action Y. SPF does not include such an action, neither in the DNS entry, nor in the RFC, which just gives you examples of what could be done in various scenarios. The result of the SPF check can and should be considered when evaluating an incoming message, I guess we all agree on that. What I disagree with is that emails should be rejected solely based on the SPF result, while ignoring all other signals - even when the domain owner published a statement which instructs you to do otherwise (to avoid the term „policy“ here). — 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.
