Domain  Check SPF record Checking… 

What is an SPF record?
----------------------

 SPF (Sender Policy Framework) is a DNS TXT record that lists the servers allowed to send email for your domain. When a receiving mail server gets a message claiming to be from you, it checks this record. If the sending server isn't listed, the message can be marked as spam or rejected. That's what stops attackers from spoofing your domain.

### The 10 DNS lookup limit

 Every include, a, mx, ptr, exists and redirect term forces a DNS query, and includes expand into more queries. RFC 7208 caps the total at 10, and going over makes receivers return a PermError, which usually breaks SPF entirely. This checker follows every include recursively so you see the real count.
