SPF Lookup Limit: The 10 DNS Lookup Rule

RFC 7208 limits SPF evaluation to ten DNS lookups, and exceeding that limit causes a PermError that breaks authentication.

What we found

Nothing to report. This record parses cleanly, stays inside the DNS lookup limit, and every include it points at answers.

Validated · 1 / 10 lookups
Paused — compare your current SPF chain with one managed include side by side. Each provider include consumes DNS lookups toward the 10-lookup limit. Flattening provider includes into one managed record… Your public SPF stays simple — SPF Manager maintains the rest.

What changes if you let us manage it

One include, whatever you add

Your record becomes a single include that we host. Adding another provider later changes what resolves behind it, not what you publish, so your own record stops growing toward the 10-lookup limit.

Provider changes are our problem

When a provider quietly starts sending from new addresses — or starts costing more lookups than it used to — we see it and republish. You never find out from a bounce.

Always current, never touched

You publish one TXT record once. From then on the addresses behind it stay correct without you editing DNS again.
