SPF Best Practices
10 Lookup Limit
SPF is limited to 10 DNS lookups. Each "include" counts as at least one lookup. Use IP addresses when possible.
Start with Soft Fail
Use ~all (soft fail) initially. Move to -all (hard fail) after confirming all legitimate senders are included.
One SPF Record
Only one SPF record per domain is allowed. If you have an existing record, merge the mechanisms.
Combine with DMARC
SPF alone doesn't prevent spoofing. Use with DMARC to get reports and enforce authentication.
Monitor your SPF and DMARC together
DDMARC shows you which senders pass or fail SPF, DKIM, and DMARC. Identify misconfigured senders before they cause delivery issues.
