Automated reports not being delivered despite successful email DNS validation

Hi all,

We’re trying to set up automated reports as part of our onboarding process however are experiencing some issues.  

We’ve configured our email domain through Mimecast and added the required SPF, MX, and DKIM DNS records. The DNS configuration test reports: “The Email DNS configuration has been validated successfully.” 

Despite everything having been set up our end and the background job indicating that each task has been completed, the automated reports generated from our custom-built reports are still not being delivered to the email addresses specified in the report settings. Instead, we keep getting email delivery failures stating that the MX records are invalid.

Has anyone encountered this issue before or found a way to troubleshoot it?

Many thanks.
