Configuring the Anti-Spam Agent - Heuristics Filter

The Anti-Spam Agent - Heuristics filter is configured in the Anti-Spam Agent Heuristics screen.

Figure 3 - 21 The Anti-Spam - Heuristics screen

To cofigure the Anti-Spam Agent - Heuristics filter:

1Select Global Policy from the Policy Manager tab.

2Click Filters. The Global Policy Filter list screen is displayed.

3Click Add. The Create New Filter screen is displayed.

4Select Anti-Spam Agent - Heuristics.

Note: You will only see this if you have not added an Anti-Spam Heuristics Filter previously.

5Click Next.

6Enter a name into the Filter Name field.

7This filter is enabled by default. Select the ‘disable’ option if you want to switch it off.

8If you want to make the filter so that it can be overwritten by a sub-policy change the Filter Permission setting to writable. The default is read-only.

9Select the Sensitivity Level. This sets how strictly RiskFilter scans messages:

•Lowest – You should not get any false positives with this setting but it is very likely that some spam messages will not be stopped.

•Low – Only messages that are definitely spam will be stopped. With this setting, false positives will be less but you also run the risk of messages that are spam getting through.

•Medium – More messages will be stopped as the criteria for deciding whether a message is spam or not, is much wider. However, some messages that are not spam may be stopped.
