Sender Policy Framework (SPF) is an e-mail validation system used to prevent e-mail spoofing by allowing domain name administrators to specify a set of authorized hosts where e-mail for the domain can be sent from. The system uses a special DNS TXT record (often called SPF record).
To set up an SPF record for your domain for use on Luna Node E-mail Services, create a TXT record with:
- Key/name: the domain name
- Value: "v=spf1 a mx ip4:172.81.176.235 ~all" (without quotes)
Note: use "v=spf1 a mx ip4:172.81.176.235 -all" to tell recipients to hard-fail the validation (instead of soft-fail) if the IP does not match.
