Setting up SPF To set up SPF, you need to add a specific TXT record to your domain's DNS settings. This record should list all the IP addresses and domains authorized to send emails on behalf of your domain. Tools like SPF Record Generator can simplify this process.
Setting up DKIM For DKIM, you need to generate a pair of cryptographic keys. The private key is used by your email server to sign outgoing emails, while the public key is added to your DNS records as a TXT record. Many email service providers offer built-in support for DKIM, making the setup process straightforward.
Setting up DMARC To implement DMARC, you need to create a DMARC policy and add it as a TXT record in your DNS settings. The policy should specify how receiving mail servers should handle emails that fail SPF or DKIM checks. You can also set up DMARC reports to gain insights into your email authentication status.
