Email security
CScore 68/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
- warnSubdomains use a weaker policy (sp=none) than the main domain (p=quarantine).
- 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.
- warnMTA-STS is in testing mode. Switch to mode: enforce once reports look clean.
- warnNo BIMI record (optional: shows your logo next to your emails in supporting inboxes).
- goodSPF record found.
- goodSPF ends with ~all: servers you have not listed are marked as suspicious (soft fail).
- 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].
- good1 MX record(s) found.
- goodTLS-RPT is set up: you receive reports about failed encrypted deliveries.
