Report domain from google

Hi,

I just followed the instructions in the knowledge base on you to add your own domain to mailbox.org. I can send and receive emails and terminal dig commands all passes. But I received this email on postmaster@mydomain.net "Report domain: mydomain.net Submitter: google.com Report-ID: 8058823383207054172" containing an .xml file with some errors.

<?xml version="1.0" encoding="UTF-8" ?>
