How to configure dmarc?

I’m having some email delivery issues.

One of the problems I’ve discovered by using mxtoolbox is my domain is missing a dmarc record.

Can anyone explain to me or point me in the right direction as to how I should configure this?

Kind regards

I followed the steps at, it asks questions and gives you the value for your TXT record. When I tested it, it said it worked… so I guess it did!

  • “working” is that context means you have created the TXT record without making any errors.
    You should not think of it as are done deploying DMARC, this is just the 1. step

Deploying DMARC can be anything from a 2 min. task, to a project taking years to complete, depending on the size and complexity of your organization.

If you can provide more detail, more specific advice can be given.
