Check record

What is it?

Sender Policy Framework (SPF) is a DNS TXT record that lists approved sending services.

Why is it important?

Receiving mail systems use SPF to detect forged senders and reduce phishing that impersonates your domain.

How do you improve it?

Publish one SPF record, include every legitimate provider, stay within the ten-lookup limit, and end with an intentional all mechanism.
