Email security
- badSPF needs about 23 DNS lookups but the limit is 10. Receivers return a permanent error, so SPF fails. Flatten or remove includes.
- badSPF includes phxrelay.tbe.taleo.net, which has no SPF record. That causes a permanent error.
- 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.
- 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], mailto:[email protected].
- good2 MX record(s) found. Mail is handled by Mimecast.
