SPF PermError — an SPF result indicating the published policy cannot be correctly interpreted and requires an administrator to fix its configuration.

SPF PermError — an SPF result indicating the published policy cannot be correctly interpreted and requires an administrator to fix its configuration.
The receiver retrieves the domain’s SPF record, evaluates its mechanisms for the sending IP in order, and produces pass, fail, softfail, neutral, temperror, or permerror.
Publish one SPF record, authorize only real senders, stay within the ten DNS-mechanism lookup limit, and choose the correct all qualifier. Test both syntax and the actual sending IP after changes.
