Hector, I think Levin's original suggestion to use the setting option like SPF AND DKIM, SPF OR DKIM, SPF only, DKIM only is excellent. It could solve a lot of problems. System administrators know best how to set up their system and for what purposes they need that setting. I can imagine a great many reasons for and against those combinations. What seems to me to be important here is that DMARC is able to use policies to solve not only common but also error states. In that case, it is able to successfully solve the problems caused by the attackers. Jan Dne 23. 6. 2023 v 19:23 Hector Santos napsal(a): > Levine makes a good point. A less complex option would be: > > auth=dkim # apply dkim only, ignore spf, dkim failure is > dmarc=fail > auth=spf # apply spf only, ignore dkim, spf failure is > dmarc=fail > > the default auth=dkim,spf SHOULD NOT be explicitly be required.
