# SPF

Also called: Sender Policy Framework

A DNS TXT record that lists the servers allowed to send email for a domain. Receiving servers check it against the domain in the hidden return path, not the From address you see.

## How this affects you

Because SPF checks the return path, what matters for Vaartix is the SPF record on your return-path subdomain, `vxmail.yourdomain`: `v=spf1 include:amazonses.com ~all`. Vaartix gives you that record when you add your domain. Your main domain's SPF record (for Google Workspace, Zoho or Microsoft 365) doesn't change. A name can only have one SPF record, so if a subdomain already has one, it can't be your return path.
