What is email authentication and why is it important?

Email authentication is a process that helps verify the legitimacy of an email sender. It's important because it helps prevent email spoofing and phishing attacks, ensuring that the emails you receive are from trusted sources.

How does email authentication work?

Email authentication works through various protocols like SPF, DKIM, and DMARC. These protocols check if the email is sent from an authorized server and if the content hasn't been altered.

What are SPF, DKIM, and DMARC?

SPF (Sender Policy Framework) specifies which mail servers are allowed to send emails on behalf of your domain. DKIM (DomainKeys Identified Mail) adds a digital signature to your emails, while DMARC (Domain-based Message Authentication, Reporting & Conformance) helps you manage how your domain handles authentication failures.

Can I set up email authentication for my personal email?

Yes, you can set up email authentication for personal emails, especially if you own a custom domain. Most email hosting services provide guides to help you configure SPF, DKIM, and DMARC.
