mediumSPF uses ~all (softfail) instead of -all (hardfail)
Softfail still lets mailbox providers accept unauthorized senders. Upgrade to -all once you're confident all legitimate senders are covered.
→ Replace ~all with -all in your SPF record.
infoDKIM could not be verified
We checked common selectors (default, google, selector1/2, mail, etc.) and found none. This is normal for providers that use custom selectors (Amazon SES, Fastmail) — DKIM may be working fine. It is NOT scored against you.
→ Confirm DKIM is set up with your mail provider. If you know the selector, you can verify it directly on the email-auth page.
