Learn how to increase your organization's email deliverability, and prevent users within it from having their identity stolen in email forgery attacks, simply by publishing relevant DNS records on your domain.

Email deliverability is a constant challenge for organizations, but this challenge is widely amplified if your domain is not properly secured to prevent attackers from using its name in email forgery attacks to exploit its reputation, which will tarnish or ruin it in the eyes of spam filters and people.

In this course, Configuring and Managing SPF, DKIM, and DMARC, you’ll gain the ability to configure your domain in a way that your legitimate emails will not be mixed up with foreign spam and phishing attacks. First, you’ll learn SPF to publish a whitelist of your email servers. Next, you’ll discover DKIM to sign your emails cryptographically against tampering. Finally, you’ll explore how to use DMARC to publish your policies for SPF and DKIM misalignments against an email's claimed author, and monitor their application with third parties. When you’re finished with this course, you’ll have the skills and knowledge of SPF, DKIM, and DMARC needed to mitigate a wide range of email security attacks against your domain, and to allow spam filters to validate the true origin of your emails.
