How do I set up email authentication for my application?
To set up email authentication, you'll need to configure your email server and implement authentication protocols like SPF, DKIM, and DMARC.
What are SPF, DKIM, and DMARC?
SPF (Sender Policy Framework) helps prevent spoofing by specifying which IP addresses are allowed to send emails on behalf of your domain. DKIM (DomainKeys Identified Mail) adds a digital signature to your emails, allowing the recipient to verify that the email was indeed sent by you. DMARC (Domain-based Message Authentication, Reporting & Conformance) builds on SPF and DKIM by providing instructions on how to handle emails that fail authentication.
How do I implement these protocols?
You can implement SPF by adding a TXT record to your DNS settings. For DKIM, you'll generate a key pair and add the public key to your DNS. DMARC also requires a TXT record in your DNS with specific policies.
Can you help me with the DNS settings?
