SPF Lookup

About SPF Lookup

SPF Lookup will list SPF records for a domain, Sender Policy Framework (SPF) is an email validation protocol designed to detect and block email spoofing by providing a mechanism to allow receiving mail exchangers to verify that incoming mail from a domain comes from an IP Address authorized by that domain's administrators. The list of authorized sending hosts and IP addresses for a domain is published in the Domain Name System (DNS) records for that domain in the form of a specially formatted TXT record. Email spam and phishing often use forged "from" addresses and domains, so publishing and checking SPF records can be considered one of the most reliable and simple to use anti-spam techniques.
