Issues (5)
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
highDMARC policy is none (monitor only)
p=none provides visibility but no protection. Spoofed mail still passes through to inboxes. Move to quarantine once you've verified legitimate senders are authenticated.
→ Once DMARC aggregate reports show your legitimate mail aligned, upgrade to p=quarantine, then to p=reject.
highMX IP 187.111.111.2 has no PTR (reverse DNS)
Gmail and Microsoft both require reverse DNS on sending IPs. Without it, mail from this host is almost always rejected or spam-foldered.
→ Add a PTR record at your hosting provider. For cloud MTAs (AWS SES, Mailgun, etc.) this is managed by the provider.
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.
