7. Where should I point my SPF Records? Sender Policy Framework (SPF) is a simple email validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain is being sent from a host authorized by that domain's administrators. The list of authorized sending hosts 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 sender addresses, so publishing and checking SPF records can be considered anti-spam techniques.	You can point SPF records as follows: SPF record for NOAM location: include:_spf.snwlhosted.com -all SPF record for EU location: include:_spf.snwlhostedeu.com -all SPF record for Encryption service: include:_spf.sonicsecuremail.com -all Note: You must turn off SPF, RBL and any other first touch checks at the mail server when using Sonicwall Hosted Email Security.
