Hosts are CNAMEs

MX records must point to a host name with A/AAAA records, not to a CNAME: mx1relay.faceworks.nl -> mx.spamexperts.com, mx2relay.faceworks.nl -> fallbackmx.spamexperts.eu, mx3relay.faceworks.nl -> lastmx.spamexperts.net

Addresses without reverse DNS

These MX addresses have no PTR record, which many receivers treat as a spam signal: 2001:550:2:61::2fc:100 (mx3relay.faceworks.nl). Ask your hosting provider to set one.

TLS

warn

no MTA-STS · no TLS-RPT · DANE on 0 of 3 MX hosts

Found

DANE (TLSA records)

MX host	TLSA	DNSSEC
mx1relay.faceworks.nl	none	-
mx2relay.faceworks.nl	none	-
mx3relay.faceworks.nl	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.

#36

BIMI

info

No BIMI record

Checks

i

Not configured

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