  • Hi,

    For your question, we could get the explanation in the description for the FQDN parameter of the New-ReceiveConnector.

    "The Fqdn parameter specifies the destination FQDN that's shown to connected messaging servers. This value is used in the following locations:
    1. In the default SMTP banner of the Receive connector.
    2. In the EHLO/HELO response of the Receive connector.
    3. In the most recent Received header field in the incoming message when.
    4. During TLS authentication."

    We need to use the FQDN rahter than the external hostname, it is a build-in feature for Exchange.

    Hope it helps.

  • It did not help as much as I had hoped.

    My reason for asking is when I test my SMTP-/Exchange-server with telnet, from the internet, I get a helo response from the server with the internal name, which is servername.domain.local, and I am not happy about my internal domain-name can be seen on the internet.
