Email security
FScore 28/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
- badNo DMARC record. Receivers have no instructions for mail that fails SPF and DKIM, and you get no reports about who sends as your domain.
- 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.
- goodSPF ends with ~all: servers you have not listed are marked as suspicious (soft fail).
- good1 MX record(s) found.
