SPF filtering is a common anti-spam measure among email providers. It is designed to prevent your emails from being marked as spam. Prevent email spoofing and secure your domain by adding SPF records to your DNS.
Email spoofing is when scammers send emails that appear to come from your domain with a fake reply-to address. They mimic your regular emails by using the same phrasing, email template, and signature to make the message appear legit. Users are prone to phishing attacks when replying to the fake reply-to address and their sensitive information can be stolen.
SPF – Sender Policy Framework – is an email validation system designed to prevent spam by detecting email spoofing. SPF records are TXT files that allow senders to include which hosts are authorized to send emails on behalf of their domain.
