    Reverse DNS does not match
    MX · The PTR name of these addresses does not resolve back to the same address: 2a00:18e0:5:3:dfe2:c743:85aa:61bc -> relay.mail-forwarder.io, 2a00:18e0:5:2:7577:4e4d:413b:f507 -> relay.mail-forwarder.io, 2a00:18e0:5:3:dfe2:c743:85aa:61bc -> relay.mail-forwarder.io, 2a00:18e0:5:2:7577:4e4d:413b:f507 -> relay.mail-forwarder.io.

    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.
