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.
Domain names connected to your hosting control panel and pointed to our network via the Skystra nameservers will automatically have an SPF record in your DNS zone and enabled. You do not need to perform the steps below and no further action is required on your part.
If you are using an external DNS and/or CDN provider (Cloudflare, etc.) – you have to add your SPF record as a DNS entry to have it enabled on your domain name, using the steps indicated below.
1. Log in to your hosting control panel
2. From the top menu, next to the Domain: field and select the domain name you want to manage
3. Click on the DNS Zones button
4. Under the Value column, locate the DNS entry that starts with v=spf1 – this is your SPF entry, keep your browser window open here
5. Open a new browser window, and log in to your external DNS and/or CDN customer portal account
6. Go to manage the DNS zones for your domain name and select to add a new TXT record (SPF records are added as TXT records in DNS zones)
