Sender Policy Framework (SPF) is an email validation system designed to prevent email spam by detecting email spoofing, a common vulnerability, by verifying sender IP addresses. SPF allows administrators to specify which hosts are allowed to send mail from a given domain by creating a specific SPF record (or TXT record) in the Domain Name System (DNS). Mail exchangers use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain's administrators.
In simple terms by creating an SPF record, you are authorizing DANAConnect to send emails with an @yourcompany.com email address.
Emails sent from DANAConnect may be marked as SPAM by your customer's email servers if you skip this step
