Overview of spam filtering

Spam Filter is an email scanning service that identifies spam and enables user-level control and management of spam. You can offer spam filtering as a service to your customers when you create a site or Service Plan.

Each email is evaluated against message rules that associate a textual pattern or characteristic with spam. Each rule is assigned a value called a score. When the text in an email matches a rule, a score is assigned to the email. If the sum of all such scores exceeds the set threshold, the message is categorized as spam.

- Note: When you enable spam filtering for a site, you automatically empower the User Administrator with spam control and management capabilities.

  The administrator can set the spam threshold that categorizes an email message as spam. Once identified as spam, he can choose to delete the spam email, have it delivered as an attachment or as a regular email to his inbox, or quarantine the email in his spam folder.

You can also use the Sendmail Reject List to reject spam. The spam filter lists and the Sendmail Reject List vary in their approach and flexibility in managing spam.

The control panel leverages the spam filtering tool SpamAssassin™ to enable spam scanning. For detailed information on SpamAssassin, please visit http://useast.spamassassin.org/index.html.
