Optimal Email Configuration Issues. APC recommends that you
select the Local SMTP Server option for the Send via setting for the
following reasons:
• If the SMTP server does not respond to the Management Card
within 20 seconds, the Email will not be sent. Therefore, it is
best to specify a local SMTP server rather than one across the
Internet, especially if the remote SMTP server is handling large
amounts of traffic.
Note: The Management Card has limited resources to queue
and transmit Email. Therefore, the Management Card
has relatively low time-out values.
• The local SMTP server will queue the Email and attempt to
send it several times to the remote SMTP server. When you
select the Recipient’s SNMP Server option, the Management
Card will try to send the Email only once.
When you select the Local SNMP Server option, you must do one of the
following:
• Enable forwarding at that server so that the server can route
Email to external SMTP servers. Typically , SMTP servers are
not configured to forward Email. Consult with your SMTP-server
administrator before changing the configuration of your SMTP
server to allow forwarding.
• Set up a special Email account for the Management Card. This
account would then forward the Email to an external Email
account.
