SPF ends in ?all (neutral)

Check id: spf.all_neutral · fix effort: low

What it means

Your SPF record ends in ?all, which means it takes no position on unknown senders. That gives you almost no protection.

The technical detail

?all yields neutral for unlisted sources. Most receivers treat it like no policy.

How to fix it

  1. Change ?all to ~all (softfail), then -all once senders are confirmed.
