4. DMARC Coverage: Crucially, that is the place you resolve easy methods to deal with emails that fail authentication. The most typical choices are:

   • p=none: This can be a monitoring coverage. It permits you to see which emails are failing authentication with out taking any motion. Use this initially to check and determine potential points.
