SPF Checker
Check if your domain has a valid SPF record and whether it is correctly configured.
What is SPF?
SPF (Sender Policy Framework) is an email authentication method that specifies which mail servers are authorised to send email on behalf of your domain. It works by publishing a DNS TXT record that lists the IP addresses and domains allowed to send email for you.
Without SPF, attackers can forge the "From" address in emails to make them appear to come from your domain. A correctly configured SPF record helps receiving servers identify and reject these forged emails.
