In the Security level section, you can select one of the predefined collections of settings (security levels) for Anti-Spam. The decision of which security level you should select depends on operating conditions and the current situation.
The following security levels are available:
Extreme. At this security level, Anti-Spam applies maximum scrutiny in spam filtering.
You are advised to select the high security level when working in a dangerous environment (for example, when using a free mail service).
Setting a high security level may lead to more frequent cases of non-spam messages being categorized as spam.
Optimal. This security level ensures an optimum balance between performance and security. This level is suitable for most situations.
Low. At this security level, Anti-Spam applies the minimum level of spam filtering.
The Low security level is recommended to set when working in a safe environment (for example, when using encrypted corporate email).
Setting a low security level may lead to fewer cases of non-spam messages being categorized as spam or probable spam.
Clicking the link causes the application to apply the Optimal security level. The link is displayed if you have modified the settings in the Advanced settings of Anti-Spam window in the Do not classify a message as spam section.
