Kaspersky Secire Mail Gateway SCL X-header not inserted

[slavkos]

We’ve deployed and configured the KSMG and it is marking SPAM messages properly in the Subject (adding the [Spam] tag), but is is not inserting the X-MS-Exchange-Organization-SCL X-header  into the message.

Because of that, SPAM messages are being delivered into Inbox folder, instead of the Junk folder. Our e-mail server is MS Exchange.

Online help document is of no use, as it says:

Based on the scan results, the program adds the X-MS-Exchange-Organization-SCL X-header to the message. This header contains the SCL rating.

Anti-Spam functionality can be configured by editing the settings file for the Anti-Spam engine. In the settings file, you can change, for example, statuses of Anti-Spam scanning of messages or the level of detail of email message information recorded in the Kaspersky Secure Mail Gateway event log.

The settings file of the Anti-Spam engine can be accessed from the Kaspersky Secure Mail Gateway Management Console in Technical Support Mode with super-user account privileges.

 

However, the header is not being inserted, and I was unable to locate this configuration file so far. Anyone has any ideas?
