Delivery Status Issue

How do I resolve this error? Emails to students from parents, teachers, colleges, etc. are getting blocked with the error shown below. How do I resolve this issue?

Thank you!!

I'd start by ensuring that SPF, DKIM, and DMARC are set up properly for your domain. See https://support.google.com/a/answer/10583557?hl=en&ref_topic=9061731&sjid=4171712519405670493-NC for the details.

Google postmaster tools (see https://support.google.com/a/topic/6259779?hl=en&ref_topic=7279058&sjid=4171712519405670493-NC) might also potentially be helpful for understanding what's going on.

@icrew Thank you! Postmaster Tools is a nice callout🙌
We had been looking for data such as that contained in the Authentication graph area.
