Problems

!

Policy: quarantine

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

#4
!

More than 5 MX records

MX · Found 7 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.

#13
!

Not configured

TLS · 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.
