and classify email as it enters your site.

■Email Firewall – This early response feature can vastly improve message

throughput by analyzing incoming SMTP connections and enabling you to

refuse connections or email messages from hosts it perceives to be hostile.

■Antivirus technology – Antivirus definitions and engines protect your

users from email-borne viruses.

■Content Compliance – These features help administrators enforce corporate

email policies, reduce legal liability, and ensure compliance with regulatory

requirements.
