Optimal Email Configuration Issues. It is recommended that you select

the Local SMTP Server option for the Use SMTP Server setting for the

following reasons:

• The Management Card will attempt to make a connection with the

selected server for up to 60 seconds. If the

SMTP server does not

respond within that 60 seconds, the email will not be sent. Therefore,

there is a higher probability that the Management Card will be able to

connect to a local

SMTP server than one across the Internet. This is

especially true when the remote

SMTP server is handling large

amounts of traffic, like

AOL or MSN.

• 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 only try

to send the email once.

When you select the

Local SNMP Server option, as recommended, you will

need to 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 in order to prevent someone from using the server to send

SPAM.

Consult with your

SMTP-server administrator before changing the

configuration of your

SMTP server to allow forwarding. Besides direct

forwarding, you can set up a special email account for the Management

Card. This account would then forward the email to an external email

account.

The Management Card has limited resources to queue and

transmit email. Therefore, the Management Card has

relatively low time-out values, particularly when compared to

a workstation or server which has hundreds of times more

processing bandwidth and storage
