DKIM (DomainKeys Identified Mail) and DMARC (Domain-based Message Authentication, Reporting, and Conformance) are important security mechanisms to protect email communications. They should be implemented by all organizations and businesses that send emails to improve email security and protect against phishing and spoofing.
- DKIM: DKIM allows an organization to take responsibility for a message in transit. It assures the recipient that the email has not been altered in transit and that it actually comes from the specified domain. This is done by adding a digital signature to the email header. All organizations sending emails should create DKIM records to verify their emails and build credibility with email services.
- DMARC: DMARC builds on DKIM and SPF (Sender Policy Framework) by adding a policy for how the recipient's email server should handle emails that fail DKIM or SPF checks. This helps prevent unauthorized actors from sending emails on behalf of your domain. By creating DMARC records, an organization can gain insight into how their emails are handled and make adjustments to improve deliverability.
Overall, the creation of DKIM and DMARC records is essential for organizations that want to ensure the integrity of their email communications and protect their brand from abuse. It is not only a good practice, but also an essential part of modern email security strategies.
