Here are steps to implement domain protection measures:
Setting Up SPF To set up SPF, you need to add a TXT record to your domain's DNS settings. This record specifies the IP addresses that are authorized to send emails on behalf of your domain.
Configuring DKIM DKIM requires generating a pair of cryptographic keys (public and private). The public key is published in your DNS records, while the private key is used to sign your outgoing emails.
Applying DMARC DMARC policies are defined in your DNS records. These policies dictate how receiving mail servers should handle emails that fail SPF or DKIM checks. You can set policies to monitor, quarantine, or reject such emails.
