1. SPF (Sender Policy Framework)
SPF is an email authentication method designed to prevent spammers from sending emails from your domain. Essentially, SPF allows the domain owner to specify which mail servers are authorized to send emails from that domain. This is done by adding a specific SPF record to the domain's DNS records. When an email is sent, the receiving mail server checks this SPF record to verify that the email is coming from a server authorized by the domain owner.
For example, if your domain is “example.com” and you have an SPF record that only includes your own mail server, any email that appears to come from “example.com” but is sent from an unauthorized server will be flagged as potential spam or rejected outright. SPF helps maintain the integrity of your email communications and protects your domain’s reputation.
