SPF (Sender Policy Framework) is an email authentication system that uses DNS to check if a mail server is authorized to send emails from your domain name.
Please note that domain names connected to your hosting control panel and pointed to our network via the Skystra nameservers and using our MX records will automatically have an SPF record enabled. You do not need to perform the steps below.
⚠️ If you are using email through Google Workspace or Microsoft 365, the default SPF would require modification as well, however, is completed for you through an automatic process. Please visit the Google Workspace email or Microsoft 365 email guides respectively to view details.
