Email security
FScore 39/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
- warnSPF ends with ?all, which tells receivers nothing. Use ~all or -all.
- warnDMARC applies its policy to only 0% of failing mail.
- warnNo DKIM key found at common selectors (google, selector1, selector2, default, k1, k2, s1, s2, ...). DKIM may still use a custom selector we cannot guess.
- warnNo MTA-STS: mail sent to you can be downgraded to an unencrypted connection.
- warnNo TLS-RPT record, so you won't hear about failed encrypted deliveries.
- warnNo BIMI record (optional: shows your logo next to your emails in supporting inboxes).
- goodSPF record found.
- goodDMARC policy is quarantine: failing mail goes to spam. Move to p=reject for full protection.
- goodDMARC aggregate reports are sent to mailto:[email protected].
- good5 MX record(s) found. Mail is handled by Google Workspace.
