Modules - Antivirus

Overview

The antivirus system scans mail messages as they pass through your mail server.

Installation

If you did not select this module to be included during the installation process, you must first install the module.

Configuration

Mail Policies

When configuring the antivirus system, you must make some mail policy decisions. There are three types of policies available:

• Bounce bounce the e-mail
• Discard - silently discard the e-mail
• Pass Through - send e-mail with warning (original sent as an attachment)

Virus Detected Policy

When a virus is detected, you can choose to either discard the message, or pass the message through. We recommend discard mode for most installations.

Banned File Extension Policy

The antivirus software not only performs virus scanning, but also manages file attachment policies. Certain types of file attachments are prone to viruses. The ability to block attachments by file extension is another layer of security for your mail system.

Banned File Extensions

Select the file extensions that you wish to ban from going through your mail system. Both internal and external mail are checked.
