TLS

no MTA-STS · no TLS-RPT · DANE on 0 of 2 MX hosts

DANE (TLSA records)

MX host	TLSA	DNSSEC
CLUSTER02.MX-RELAY.COM	none	-
multicopy-nl.mail.protection.outlook.COM	none	-

Checks

!

Not configured

MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.

#32
i

Not configured

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.

No BIMI record

Not configured

BIMI shows your logo next to your mail in supporting mail clients. It requires DMARC enforcement.
