SPF Record(s) - Missing or Invalid

What has been found

SPF Record(s) - Missing or Invalid

SPF allows domain owners to publish where they expect mail to originate for the domain. This helps protect against mail spoofing. SPF records were found to be Missing or Invalid

Why this is a potential risk

Without a valid SPF record, unauthorised senders can forge email headers to make messages appear as though they originate from your domain. This increases the likelihood of successful phishing or business email compromise (BEC) attempts, damaging organisational reputation and trust.

Misconfigured or absent SPF records can also cause legitimate email to be marked as spam or rejected by recipient mail servers. Maintaining a valid SPF record is a foundational control in email authentication and should be implemented alongside DKIM and DMARC for comprehensive protection.

Potential solutions/Improvements

SPF is configured via DNS. Contact your internet domain registrar and ask for help with DNS configuration.

How to verify it is resolved:

  • Query the domain’s DNS (e.g. nslookup -type=txt yourdomain.com) to confirm a valid SPF record is present.

  • Test the SPF record with a verification tool (e.g. MX Toolbox)

  • Send test emails to confirm SPF alignment and ensure messages pass SPF checks in the headers.

  • Review mail logs or DMARC reports for unauthorised sending activity.
