The control panel offers two spam filter options - the Sendmail Reject List and Spam
Filtering service - that vary in their approach and flexibility in

panel to enable spam filtering capability for your site users. The service
is automatically available to your users when enabled for the site by
your service provider.
While the Sendmail Reject List enables effortless global
control on relay of spam email messages to site users, the Spam Filtering
service allows for discretionary management of spam by the users themselves.
Email sources that you identify as illegitimate can be blocked
from being delivered to any user of the site.

List allows global control on the relay of email messages to site users.
The email sources included in the Reject List are blocked from being delivered
to any site user.

the site level correspondingly reduces the scale of spam filtering at
the user level. This releases system resources that would otherwise be
utilized for scanning.
Rejecting spam at
the site level reduces the risk of email viruses infiltrating the network.
While the Sendmail Reject List only allows rejection of spam
email messages, the Spam Filtering service allows discretionary management of spam.
The Spam Filtering
service allows flexibility in controlling and managing spam. The User
Administrator can review the email messages and choose to delete spam
messages, have them delivered as an attachment, or quarantine them in
a spam folder.
Filtering at the user level introduces security risks
posed by email viruses.
