Enable SPF alignment in ServiceNow for your domain
You may notice that ServiceNow emails are not authenticated via SPF, even after you have added ServiceNow to your domain's configuration. This is likely caused by ServiceNow not sending SPF aligned-mail and can be corrected by making sure the return path of the ServiceNow emails is changed to match your domain.
To that end, please contact your ServiceNow service administrator and make sure they are turning on SPF alignment in ServiceNow for your domain.
As always, if you have any questions, please don't hesitate to submit a ticket.
