Mail Server Considerations

ALOM-based manageable servers use mail services to send host event notifications to the N1 System Manager.

If you plan to manage ALOM-based manageable servers, you must decide whether to use the secure N1 System Manager internal mail service, or install. configure, and use a full mail service.

Using an external mail server for event notifications exposes the N1 System Manager to man in the middle attacks, denial of service attacks, and other external security risks.

• The secure N1 System Manager embedded mail service does not require configuration or installation. The only requirement is that port 25 must be available and that port 25 is not in use on the management server.

• If you choose to use a mail service, configure the mail service as described in Configuring the Management Server Mail Service and Account in Sun N1 System Manager 1.2 Site Preparation Guide.

For information about which manageable servers are ALOM-based, see Table 2–5.
