SPF Record Failure Issue

                                                 SPF Record Issue

Hi Friends,
In this article I am going to introduce you with a common issue of Email organization which called "SPF record not found"

If you're not able to send the emails due to SPF record are not found or not valid.

What is SPF??????

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

 Firstly we have to check the emails logs and on the behalf of that logs, we analyze that email is rejecting due to SPF record failure.
Here I am attaching a screenshot of SFP record failure issue.
