About SPF Records
What is SPF?
SPF (Sender Policy Framework) is an email authentication method designed to prevent spoofing. It
allows domain owners to specify which mail servers are permitted to send email on behalf of their
domain.
Common SPF Mechanisms:
- a - Matches if the domain has an A record
- mx - Matches if the domain has an MX record
- include - Include another domain's SPF record
- ip4 - Specify IPv4 addresses
- ip6 - Specify IPv6 addresses
Failure Policies:
- -all - Hard fail (recommended for most cases)
- ~all - Soft fail (good for testing)
- ?all - Neutral (not recommended)
- +all - Pass all (dangerous - avoid)
