You can remove the internal address and hostname using the “header firewall” which removes certain rights for the builtin user “Anonymous Logon”. So we remove the ExtendedRight for “ms-Exch-Send-Headers-Routing” for external SMTP-Connector.

First check the access rights of your external connector:

Get-SendConnector “EXTERNAL-CONNECTOR-NAME” | Get-ADPermission | Where-Object { $_.extendedrights –like “*routing*” | fl user, *rights

Be aware to use the right spelling for your Exchange servers’ language:

English OS:

Remove-ADPermission –id “EXTERNAL-CONNECTOR-NAME” -AccessRight ExtendedRight -ExtendedRights “ms-Exch-Send-Headers-Routing” -user “NT AUTHORITY\Anonymous Logon”

German OS:

Remove-ADPermission –id “EXTERNAL-CONNECTOR-NAME” -AccessRight ExtendedRight -ExtendedRights “ms-Exch-Send-Headers-Routing” -user “NT-AUTORITÄT\Anonymous-Anmeldung”

Change FQDN:

Set-SendConnector -id “EXTERNAL-CONNECOR-NAME” -FQDN:mail.company.com
