Configuring Server-Based Antispam (NSM Procedure)

Antispam filtering allows you to use both a third-party server-based spam block list (SBL) and to optionally create your own local whitelists (benign) and blacklists (malicious) for filtering against e-mail messages. The antispam feature is not meant to replace your antispam server, but to complement it.

To configure server-based antispam:

  1. In the NSM navigation tree, select Device Manager > Devices.
  2. Click the Device Tree tab, and then double-click the device for which you want to configure server-based antispam.
  3. Click the Configuration tab. In the configuration tree, select Security > Utm > Feature Profile > Anti Spam.
  4. Select Symantec Sbl and enable the feature.
  5. Expand Symantec Sbl and select Profile.
  6. Add or modify antispam profile settings as specified in Table 226.
  7. Click one:
    • New—Adds a new profile.
    • OK—Saves the changes.
    • Cancel—Cancels the modifications.
