Domain information uniquely describes the site where a computer is located and generally includes the machine (host) name, a department (optionally), and the site's organization or country. MMDF uses domain descriptions to deliver mail messages to the appropriate locations. See ``Domain names''. Note that a fully qualified domain name uniquely identifies a machine, but not the path by which messages reach that machine.
Start the Domain Administration Manager by opening the Mail window as described in ``How to start a Mail manager'', double-clicking on the MMDF_Advanced_Admin icon, then double-clicking on the MMDF Domain Admin icon. The Domain Administration Manager displays a list of existing domains.
Use the Domain Administration Manager to add or remove a domain and to view or modify domain parameters.
