Setting up DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) records is crucial for email authentication. These records help in preventing email spoofing and improving your email deliverability. To set up DKIM, you need to generate a public-private key pair and add the public key to your domain’s DNS records. For SPF, you need to create a DNS TXT record that specifies which mail servers are permitted to send email on behalf of your domain.
