So we host a mailing list for domain X, the MX record points to us, we are domain y.
If we have Dmarc set to "no dmarc mitigations" I can send a message from my email in domain Y and it goes to the list in domain x and is processed and sent out.
If I set the dmarc to "replace with list address". the same message gets shunted. I included the logs below
Not sure why it is trying to contact publicsuffix.org?
