SPF references records that don't exist

Check id: spf.void_lookups · fix effort: medium

What it means

Your SPF record points at email services that no longer exist. That dead weight can break authentication for the services you still use.

The technical detail

More than two mechanisms resolve to nothing. RFC 7208 lets receivers permerror after two void lookups.

How to fix it

  1. Remove includes whose target domains no longer publish SPF.
  2. Rescan; the observed data lists the dead references.
