What is an SPF Record?

SPF or Sender Policy Framework is a DNS record that indicates mail exchanges in which hosts are authorized to send mail for a domain. An SPF record is a type of TXT(text), and its purpose includes essential notices regarding the domain. They are used because the SMTP protocol does not authenticate the “from” address in an email. Without it, attackers may easily impersonate the sender’s email address. This works so that the attackers or spammers can edit the From address to make it look like they are sending from an email address to your domain. This action is also known as email spoofing, which uses the user’s private information and can decrease the reputation of the IP address where the domain is pointed, which may lead to blocking. That is why using the SPF record is crucial when configuring the domain.
