SPF finding
Too many SPF lookups
Evaluating the record costs more than the ten DNS lookups the specification allows, so it fails permanently.
Finding code
spf_too_many_lookups
This finding appears in the findings array of
the spam checker and
the POST /v1/sender API response when the
condition above is detected.
How to fix it
The fix.
Flatten includes or use ip4/ip6 mechanisms where possible. Each include, a, mx, ptr, and exists mechanism costs one DNS lookup against the limit of ten.
