Email security
DScore 64/100 across SPF, DMARC, DKIM, MTA-STS and BIMI.
- badSPF needs about 13 DNS lookups but the limit is 10. Receivers return a permanent error, so SPF fails. Flatten or remove includes.
- warnDMARC has no rua= address, so you receive no reports about mail sent as your domain.
- warnDKIM key found (selector: mail, mandrill) 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 marked as suspicious (soft fail).
- goodDMARC policy is reject: mail that fails authentication is blocked.
- good1 MX record(s) found. Mail is handled by Yandex 360.
