SPF-LOOKUPS-EXCEEDED
SPF exceeds the 10 DNS lookup limit
What it means
Each include, a, mx, ptr, exists and redirect counts, recursively. Past ten, receivers stop and return permerror.
How to fix it
- 1Remove includes for services you no longer use.
- 2Replace includes that resolve to fixed addresses with ip4/ip6 mechanisms.
- 3Use a subdomain for bulk senders so each record stays small.
Re-check after the change
DNS changes can take up to the record's TTL to be seen; use Re-run on the result page to bypass our 10-minute cache.
