4-4 Content Filtering and Optimizing Scans
v1.0, September 2009
Configuring E-mail Protection
The STM lets you configure the following settings to protect the network’s e-mail communication:
• The e-mail protocols that are scanned for malware threats.
• Actions that are taken when infected e-mails are detected.
• The maximum file sizes that are scanned.
• Keywords, file types, and file names in e-mails that are filtered to block objectionable or high-
risk content.
• Customer notifications and e-mail alerts that are sent when events are detected.
• Rules and policies for spam detection.
Customizing E-mail Protocol Scan Settings
If you have used the Setup Wizard, you might have already configured the e-mail policies; the
(e-mail) Policy screen allows you to modify these settings.
To configure the e-mail protocols and ports to scan:
1. Select Email Security > Policy from the menu. The (e-mail) Policy screen displays.
