Unprotected as in "without SPF record"? Which would produce
a SOFT FAIL or something on the final destination end?
No record results in NONE. A policy only enumerating the IPs
for a PASS leaving anything else (?all) as NEUTRAL should have
a very similar effect in your scenario.
Interesting. Thanks.
