TLS

warn

no MTA-STS · no TLS-RPT · DANE on 2 of 3 MX hosts

Found

DANE (TLSA records)

MX host	TLSA	DNSSEC
incijfers-nl.mail.protection.outlook.com	none	-
wm.abf.nl	3 0 1 8229aabe25db7b00…	Yes
ml.abf.nl	3 0 1 8229aabe25db7b00…	Yes

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
!

Not configured

MTA-STS or DANE is used without TLS-RPT, so you get no reports when senders fail to deliver because of TLS problems. Publish _smtp._tls TXT "v=TLSRPTv1; rua=mailto:...".

#35
!

Not all MX hosts use DANE

These MX hosts publish no TLSA records, so mail to them is not protected by DANE: incijfers-nl.mail.protection.outlook.com.
