criticalNo SPF record
This domain has no SPF record. Most mailbox providers will downgrade or reject mail that claims to be from this domain.
→ Publish a TXT record at the apex: v=spf1 include:_spf.yourprovider.com -all
lowDMARC policy is quarantine, not reject
Quarantine sends unauthorized mail to spam. Reject blocks it outright. Move to reject once DMARC reports show no legitimate senders being affected.
→ Change p=quarantine to p=reject once you trust your reports.
lowOnly one MX host
Single MX means any outage or block at that host results in mail loss or bounces. Industry best practice is at least two MX records at different hosts.
→ Add a secondary MX at a different provider or a backup MX service.
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.
