SPF allows a domain owner to publish a list of servers that are allowed to send on behalf of a domain. When processing a domain’s DMARC data, dmarcian uses the domain’s SPF record to identify IPs that are authorized by the domain.
To fulfill dmarcian’s mission of spreading DMARC everywhere, partnering with Managed Service Providers (MSP) is essential. In order for that partnership to be successful, dmarcian created a solution that gives MSPs the functionality, tools and education to manage their clients’ DMARC projects through one application.
As your DMARC advocate, we continue our lofty goal of cataloging each of the most popular sources, their DMARC capabilities and providing practical guidance on “how to” configure each to send DMARC-compliant messages.
