MX recordsnone - the scanned host was probed directly as a mail server
Mail ports
Each mail port is probed with a full TLS handshake - STARTTLS on 25, 587, 143 and 110, implicit TLS on 465, 993 and 995 - to read the certificate actually bound to it. This host publishes no MX record, so nothing here is scored - the ports are shown for reference.
