Email security
- warnSPF uses the deprecated 'ptr' mechanism, which is slow and ignored by some receivers.
- warnSubdomains use a weaker policy (sp=none) than the main domain (p=reject).
- 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 rejected (hard fail).
- goodDMARC policy is reject: mail that fails authentication is blocked.
- goodDMARC aggregate reports are sent to mailto:[email protected].
