Configure commercial bulk email filter analysis

Steps

  1. (If applicable) Mark the check box Use the results of the email hybrid service analysis for on-premises commercial bulk email analysis.
    This option only displays when the Email Security Hybrid module is configured and running.
  2. From the section Filter Properties, select the sensitivity level for the filter:
    • Normal: Analyze email source

      Use this option to set the filter to detect email only from indirect (third-party) sources of bulk email.

    • High: Analyze email source and content

      Use this option to set the filter to detect both direct and indirect sources of bulk email. This is the default.

  3. (Optional) Mark the check box Bypass antispam analysis if message size exceeds.
    In the text field, enter a message size in KB (default is 3072). Selection indicates to use message size to determine whether antispam analysis is bypassed.
  4. Configure additional filter settings and click OK. The commercial bulk email filter settings are saved.
    A commercial bulk default filter action can be used along with this filter. See Managing filter actions.
