Introduction

Recently came across Microsoft’s Article that free dmarc monitoring is available for Office 365 domains, It seems microsoft has done partnership with valimail, We will today see how to create and publish dmarc monitoring through valimail.

Here is one point to consider that this step will be applicable for a domain, which doesn’t have associated dmarc record, if you want to do this for any domain with existing dmarc then you would have to be careful and first make note of current dmarc and then created those in valimail as soon as your account is activated.

valimail controls name server of _dmarc.domain.com hence all dmarc record will be resolved by them and you can’t have multiple dmarc records.
