In the "Licensing" section, you can "Enable" / "Disable" the KAS filter (at server level) via the related button.
This is the same action as enabling the Kaspersky-AV filter via the "Security & filtering" → "AntiVirus & AntiSpam" → "Supported Applications" tab.
Do not enable the Kaspersky AntiSpam filter if the Kaspersky AntiSpam service is not running. To start this service go to "Services" → "Services Management".
In the "Configuration & Updates" section, you can set the working directory for KAS via the related text box.
Click on the "Configure" button under Updates in order to set the proxy server for retrieving the updates of the Kaspersky AntiSpam application. A new window will open, allowing you to specify the IP and port of the proxy server, as well as the login details (username and password) for authentication. To enable the "NTLM authorization on proxy server", check the corresponding option. Click "Save Configuration" to save the changes.
Use the "Update now" button to get the latest AV database updates. The "Update status" and "Last update on" provides you with information on the performed upgrades.
Under "AntiSpam Scanning", set the maximum size of emails to be scanned, and the number of threads to be used for scanning. To enable the scanning of messages with internationalized content or having a specific type of file as attachment (Text, HTML, PDF, MS Office or RTF), simply check their corresponding check-boxes.
You can also set the maximum number of emails that can be queued for scanning.
The "Spam Identification Methods" section allows you to select the technologies to be used by Kaspersky for AntiSpam filtering. Use the available check-boxes in order to enable the scanning of messages based on the analysis of their content (Kaspersky's Content Filtration technology), attached graphics (Image Recognition technology), Kaspersky's default DNSBL lists (Kaspersky's built-in Domain Name Server Black Lists delivered with updates), Kaspersky's default SURBL lists (built-in Spam URL Real-time Black Lists received with updates), Urgent Detection System, or Heuristic Analyzer. Learn more on the Kaspersky website.
Messages with obscene content or in languages such as Chinese, Korean, Thai, and Japanese can also be automatically treated as Spam by enabling their associated check-boxes.
You can set additional situations when the Kaspersky AntiSpam application should consider messages as Spam in the "Additional Spam Indicators" section. E.g. when the "From" and/or "To" email headers contain digits, the "From" header does not contain a domain name, the "Subject" email header exceeds 250 characters or contains a digital identifier etc.
Recognition Strictness allows you to set the "Level of strictness in considering email messages Spam" by simply moving the related slider to the left or to the right. The selected level will be highlighted in orange. Please note that the filtering level values are based on the enabled Spam indicators and that they are cumulative (i.e. setting the level to "High" will automatically include the "Minimum" and "Standard" levels).
Once your changes are complete, save them by clicking the "Save Configuration" button.
