Could not be checked

The MTA-STS lookup failed, so this could not be checked: DNS query for _mta-sts.itfryskegea.nl failed: read udp 46.225.38.91:60365->8.8.8.8:53: i/o timeout

TLS-RPT lets senders report TLS delivery problems to you. It is most useful together with MTA-STS or DANE.

#35
i

Not used

No MX host publishes TLSA records. DANE lets senders verify your mail server's certificate through DNSSEC; it requires DNSSEC on the MX host's zone.
