What is the DMARC Info tool?
The purpose of the DMARC Info tool is to provide a template for domain administrators to make changes to their domain’s SPF records and modify published DNS with the goal of being able to secure the use of their domain using DMARC.
This tool is intended to enhance - not replace - existing policies and procedures for managing DNS SPF records.
If you would like assistance managing your DNS SPF record, please contact DoIT Help Desk and request your case to be escalated to the O365 Technical Functional team.
