When an email message comes in your inbox, Anti-Spam checks it for spam and useful mail. The component sums up
the ratings of each spam (useful mail) item and calculates the resulting spam rate. The larger the spam rate, the higher
the probability that such mail contains spam. A message is recognized by default as useful mail if its spam rate does not
exceed 60. If the spam rate is higher than 60, such a message is considered to be potential spam. If the value exceeds
90, the message is considered spam. You can modify the threshold values for the spam rate.
To change the spam rate thresholds, perform the following steps:
1. Open the application settings window.
2. In the left part of the window, in the Protection Center section, select the Anti-Spam component.
3. Click the Settings button in the right part of the window.
The Anti-Spam window will be displayed.
4. On the Expert methods tab, use the Spam rate section to configure the spam rate values using the
corresponding sliders or entry fields.
USING ADDITIONAL FEATURES AFFECTING THE SPAM RATE
The result of spam rate calculation can be affected by additional message characteristics, for example, the absence of a
recipient's address in the "To" field or a very long message subject (over 250 characters). When present in a message,
such signs increase the probability of its being spam. Consequently, the spam rate will increase. You can select which
additional characteristics will be taken into account during message analysis.
To use additional characteristics which increase the spam rate:
1. Open the application settings window.
2. In the left part of the window, in the Protection Center section, select the Anti-Spam component.
3. Click the Settings button in the right part of the window.
The Anti-Spam window will be displayed.
4. On the Expert methods tab, click the Additional button.
5. In the Additional window which opens, check the boxes next to the characteristics which should be taken into
account during message analysis and which increase the spam rate.
SELECTING A SPAM RECOGNITION ALGORITHM
Anti-Spam analyzes email messages using spam recognition algorithms.
To enable the use of a spam recognition algorithm when analyzing email messages:
1. Open the application settings window.
2. In the left part of the window, in the Protection Center section, select the Anti-Spam component.
3. Click the Settings button in the right part of the window.
The Anti-Spam window will be displayed.
4. On the Expert methods tab, in the Recognition algorithms section, check the appropriate boxes.
