Thanks for your quick response und the links :-)

When I switch list configuration to
   Anonymous list: No
   DMARC mitigation action: No DMARC mitigatins
everythings works fine, rspamd is fine with my mail.

But with
   Anonymous list: Yes
   DMARC mitigation action: Replace From: with list address
I get the SPOOFED_UNAUTH.


First of all, DMARC mitigations are not applied to anonymous lists because the From: header in mail from an anonymous list is already the list address.

That said, it looks like the issue is caused when the From: address is the list address. I don't know why that would be but I'm guessing what you need is some setting in mailcow/rspamd to authorize the list address.
