    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 209.250.250.12 -> 209.250.250.12.vultrusercontent.com.
    #30
  • !
    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.
