Email security
CScore 72/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
- warnSPF uses 8 of the 10 allowed DNS lookups. Adding another service may break it.
- warnSubdomains use a weaker policy (sp=none) than the main domain (p=quarantine).
- warnDKIM key found (selector: selector1) but it is only 1024 bits; 2048 is recommended.
- 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 rejected (hard 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].
