SPF is normally published as a TXT record beginning with v=spf1; use the value supplied by your email services.
Step by Step
- List the services that legitimately send mail for the domain.
- Review the existing TXT records for an SPF entry.
- Follow each mail provider's SPF instructions.
- Combine authorized senders into one valid SPF policy rather than creating multiple independent SPF records.
- Save and validate the resulting record.
If That Doesn't Work
- Multiple SPF records for the same domain can cause SPF evaluation errors.
- Do not blindly copy another company's SPF value.
