In case you didn't know or realize, what DMARC specifies for p=reject is actually a real felony crime in Germany (no kidding!), and this may apply to all over Europe (since the basic idea was spread out all over europe with a EU directive), unless each individual receipient(!!) has explicitly opted-in for this to happen. It should be fairly easy to get a cease-and-desist order against European ISPs for blocking EMail on DMARC p=reject. It also should stop since it is technically wrong. It is the tail trying to wag the dog and some form of company-level bullying. Get all those stupid MUAs fixed that misrepresent the meaning of rfc5322.From, and in particular the meaning of rfc5322.From when a rfc5322.Sender is present in the same message. -Martin
