This is a MailMarshal Node-specific setting, and it may be necessary to configure each node as desired.

  • Open MailMarshal Configurator.
  • Select Server and Array Configuration. 
  • Select the desired node or server name.
  • Right-click on the server name and select Properties.
  • Enter the desired HELO name under Advanced | Server Host Name.

Now if you telnet you server from the internet on port 25 you will see the correct name in the welcome string.
