Blacklist Messages Based on MIME Language

  1. In the Domain Level Control Panel, select Incoming - Protection Settings > Blacklist Filtering Rules.
  2. Click on + Add rule to create a new rule:
  3. If the Use advanced custom filtering rules option is activated in your User's Profile page, the Add a new advanced blacklist filtering rule dialog is displayed. If not activated, the Add a new simple blacklist filtering rule dialog is displayed.
  4. Give the rule a name in the Rule name field.
  5. In the Match dropdown, select Language.
  6. Ensure is is selected from the 2nd dropdown.
