SPF (Sender Policy Framework) is an email authentication method designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain is being sent by an authorized mail server.
What is SPF? SPF is a text record that lists the mail servers authorized to send emails from a domain. When an email is received, the receiving server checks the SPF record of the sender's domain to ensure that the email came from an authorized server.
How SPF Works?
- The sender's email server includes the SPF record in the email headers.
- The receiving email server checks the SPF record to see if the email is from an authorized server.
- If the email passes the SPF check, it is considered authentic and is delivered. Otherwise, it may be marked as spam or rejected.
Why Use SPF?
- Prevent Email Spoofing: SPF helps prevent spammers from using your domain to send malicious emails.
- Improve Email Deliverability: By using SPF, you can improve the deliverability of your emails by ensuring that they are not marked as spam.
How to Set Up SPF?
- Create an SPF record for your domain.
- Add the SPF record to your DNS settings.
- Verify that the SPF record is working correctly.
