SPF record: The basic you need to know

An SPF record (Sender Policy Framework) is a type of DNS TXT record that identifies which mail servers are authorized to send an email on behalf of your domain. It works by listing the IP addresses or subnets allowed to send emails from your domain. By setting up an Sender Policy Framework record, you can help ensure that only legitimate emails from authenticated sources reach your recipients’ inboxes and prevent spammers and phishing efforts from sending disguised messages with “spoofed” sender domains. For example, if someone attempts to spoof a message using your domain in their From address, any receiving server with access to an SPF check will reject it since it won’t pass authentication.
