Enabling a server to receive mail sent over SMTP routing

To set up a server to receive SMTP-routed messages, you must enable the SMTP Listener. Then the server can "listen" for SMTP traffic over the TCP/IP port (usually port 25) and receive SMTP messages in the MAIL.BOX database(s).

About this task

Enabling the SMTP listener causes the server SMTP task to start up automatically every time the server starts. Disabling the SMTP listener prevents the SMTP task from starting up when the server starts.

Note: Do not add SMTP as a task to the task list in the NOTES.INI file or this feature will not work.

    Table 1. Basics tab fields



    Fully qualified Internet host name

    The server's complete combined host name and domain name, including the top-level domain. For example, smtp.renovations.com; smtp is the host name; acme is the second-level domain; and .com is the top-level domain.

    In the absence of a Global Domain document, the Router uses the entry in this field to determine the local Internet domain. Typically, the fully qualified host name is added to the Server document during server setup or by the Administration process (AdminP). A routing loop can result if this field does not contain a valid entry.
