You can manage the addition of information X-headers to messages. For example, you can disable the addition of KSMG information X-headers to the headers of messages that are sent outside the organization to prevent disclosing the presence of KSMG in the infrastructure.
To enable or disable the addition of X headers to scanned messages:
- In the application web interface window, select the Settings → General → Message processing section.
- Use the
Add X-headers to message headers
toggle switch to enable or disable the addition of X-KSMG- X-headers. - Use the Add header X-KSMG-AntiVirus-Status to message MIME parts toggle switch to enable or disable the addition of a header to the MIME parts of messages scanned by the Anti-Virus module.
This toggle switch is available if adding X-headers to message headers is enabled.
The header is added to the MIME parts of the message if the Anti-Virus module assigned the Infected, Error, or Encrypted status to the message.
X-headers of MIME parts are not processed by the rules.
- Use the Add X-MS-Exchange-Organization-SCL header to headers of spam and probable spam messages toggle switch to enable or disable the addition of
X-MS-Exchange-Organization-SCL
X-headers to the headers of messages that the application considers to be spam or probable spam.A message is considered spam if the Anti-Spam module scans it and assigns the Spam status.
If this option is enabled, the
X-MS-Exchange-Organization-SCL
header with a value of 9 is added to the headers of messages with the Spam status.A message is considered probable spam if the Anti-Spam module scans it and assigns the Probable spam status. If this option is enabled, the
X-MS-Exchange-Organization-SCL
header with a value from 0 to 9 is added to the headers of such messages. - Use the
Add X-MS-Exchange-Organization-SCL header to headers of non-spam messages
toggle switch to enable or disable the addition of X-MS-Exchange-Organization-SCL X-headers to the headers of messages that the application does consider to be spam.A message is not considered spam if the Anti-Spam module scans it and assigns one of the following statuses.
- Not detected.
- Mass mail.
- Formal message.
- Trusted.
If this option is enabled, the
X-MS-Exchange-Organization-SCL
header with a value of-1
is added to the headers of messages that have the listed statuses. - Click Save.

If a rule containing actions on headers is applied to a message after adding X-headers, the added X-headers may be edited or removed, or X-headers defined in the rule can be added to them.
