Configuring Anti-Spam protection

Before configuring Anti-Spam protection in the message processing rule, make sure that the Anti-Spam module is enabled in general protection settings.

To configure Anti-Spam protection in the message processing rule:

In the application web interface window, select the Rules section.
In the rule table, select the rule for which you want to configure Anti-Spam protection.
This opens the View rule window.
Click Edit.
Rule settings become editable.
In the left pane, select the Anti-Spam section.
Use the toggle switch to the right of the section title to enable or disable Anti-Spam scanning of messages that match rule criteria.
By default, Anti-Spam protection of messages is enabled.
If you have disabled Anti-Spam protection at the previous step, configure Anti-Spam module settings applied to the following objects based on the results of the scan:
- Spam.
  1. Under If spam is detected, in the Action group of settings, select one of the following actions to take on messages containing spam:
    - Delete message.
    - Reject.
    - Skip.
    The Skip action is selected by default.
  2. If you want to automatically place in Backup the messages that are recognized as spam, turn on the Put original message to Backup toggle switch.
    This toggle switch is off by default.
  3. If you want tags to be added automatically to the beginning of the subject of messages that contain spam, in the Text to add to message subject field, enter the text of the tags.
    By default, the [Spam] tag is added.
- Probable spam.
  1. Under If probable spam is detected, in the Action group of settings, select one of the following actions to take on messages containing probable spam:
    - Delete message.
    - Reject.
    - Skip.
    The Skip action is selected by default.
  2. If you want to automatically place in Backup the messages that contain suspected spam, turn on the Put original message to Backup toggle switch.
    This toggle switch is off by default.
  3. If you want tags to be added automatically to the beginning of the subject of messages containing suspected spam, in the Text to add to message subject field, specify the label text.
    By default, the [Probable spam] tag is added.
- Mass mail.
  1. Under If mass mailing is detected, in the Action group of settings, select one of the following actions to take on mass mail:
    - Delete message.
    - Reject.
    - Skip.
    The Skip action is selected by default.
  2. If you want to automatically place in Backup the messages that are recognized as mass mail, turn on the Put original message to Backup toggle switch.
    This toggle switch is off by default.
  3. If you want tags to be added automatically to the beginning of the subject of messages containing suspected spam, in the Text to add to message subject field, enter the text of the tag.
    By default, the [MASSMAIL] tag is added.
Under Additional settings, turn on the relevant toggle switches:
1. Use graphical image processing technologies if you want to use the GSG technology that identifies images containing text to analyze such text for being spam. The text is recognized regardless of whether it has been modified, rotated in the image, hidden in "noise" or otherwise modified to conceal the purpose of the image.
2. Unicode spoofing protection if you want to enable Unicode spoofing protection. If Unicode spoofing is detected, the message is considered to be spam. The application adds the unicode_spoof tag to the X-KSMG-AntiSpam-Method message header.
  The application scans for Unicode spoofing only in the values of the MAIL FROM command from the SMTP session, as well as in the From, Sender, Reply-To MIME headers of the message.
Click Save.

Anti-Spam protection is configured. The specified settings are applied to messages that match the rule criteria.

To ensure that the configured settings are applied by KSMG, make sure that Anti-Spam protection is enabled for the rule and the configured rule is enabled.
