DANE (TLSA records)

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.

  Not configured

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