A carefully tailored SPF record will reduce the likelihood of your domain name getting fraudulently spoofed and keep your messages from getting flagged as spam before they reach your recipients.
Sender Policy Framework (SPF) is an email validation system designed to prevent spam by detecting email spoofing.
What does SPF record do?
A Sender Policy Framework (SPF) record is a type of Domain Name System (DNS) record that can help to prevent email address forgery. Adding an SPF record can help prevent others from spoofing your domain. You can specify which mail servers are permitted to send email on behalf of your domain.
What does SPF fail mean?
~ SoftFail, an IP that matches a mechanism with this qualifier will soft fail SPF, which means that the host should accept the mail, but mark it as an SPF failure.
How does the Sender Policy Framework SPF aim to reduce spoofed email?
Spoofed e-mails, i.e. forging the sender address to the exact character, leave the recipient no possibility of detecting the forgery. The sender policy framework (SPF) allows you to define which servers are authorized to send emails from your domain. The aim is to reduce the risk of spam and phishing e-mails.
