DMARC implementation can vary in complexity depending on the organization’s existing email infrastructure and level of technical expertise. However, generally speaking, the process involves the following technical steps:
1. Publish DMARC record: The first step is to publish a DMARC record in the organization’s DNS configuration. This record states the organization’s email authentication policies and how to handle failed messages.
1. Configure SPF and DKIM: The organization must also configure Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) authentication protocols to ensure that their email is properly authenticated.
1. Monitor email traffic: To get a better understanding of the organization’s email flow, they should start monitoring their email traffic for several weeks or months beforehand. This will help determine who is sending email on their behalf and what types of messages are being sent.
1. Analyze DMARC reports: Once DMARC is implemented, the organization receives detailed reports of email authentication failures. They can analyze these reports to identify issues and take appropriate actions to improve email deliverability.
Overall, while DMARC requires some technical expertise, there are plenty of resources and tools available to ease the implementation process. Furthermore, because DMARC builds upon existing email authentication protocols, the barriers to entry are relatively low.
