SENDER POLICY FRAMEWORK
Sender Policy Framework or SPF is an email validation mechanism to detect and prevent email spoofing. An administrator can specify the mail server name or list of servers from which mails will be sending for that domain in its DNS record. SPF data in DNS record will be saved as TXT format. Remote server can check the SPF records while receiving a mail and confirm if that mail was originated from correct MX servers. If not, it can perform the actions specified in qualifiers section.
