Checks

SPF record found

The domain publishes a single SPF record and this scan did not flag it as overly broad.

Why it matters

SPF is how receivers check the sending host against a list you published.

What to do

No SPF change is required for this result. Keep the record to one TXT and under 10 DNS lookups.

Reference

SPF records specify which hosts may send mail for the domain.
