Ratings
- Very Good – strong and complete configuration.
- Good – secure configuration with minor optimization potential.
- Needs Attention – an important recommendation is missing.
- Poor – several important records are missing or weak.
- Critical – a serious mail or domain configuration issue was detected.
DKIM selectors cannot be discovered reliably from DNS. The tool checks common selectors and lists every selector tested.
