- An SPF record is a TXT record added to your domain with the following format
_v=spf1 include:[permitted-sender-1] include:[permitted-sender-2] … include:[permitted-sender-3] ~all_
- If your domain does not have an SPF record, create a new TXT record with the following value and a TTL of 3600 seconds.
_v=spf1 ip4:126.96.36.199 ~all_
- If your domain already has an SPF record, you must modify that existing record by adding
_ip4:188.8.131.52 before the ~all_
- For example, if your domain already has an SPF record as follows
_v=spf1 include:spf.protection.outlook.com include:servers.mcsv.net ~all_
- The resulting record should look like
_v=spf1 include:spf.protection.outlook.com include:servers.mcsv.net ip4:184.108.40.206 ~all_
