Adding a Monitoring Rule

  1. Go to Administration > System Settings > Operation Mode.
  2. Click Add Rule.

    The Add SPAN/TAP Mode Rule window appears.

  3. Type the Source IP address, Destination IP address, and SMTP port to monitor.
    Note:

    If a field is empty, all SMTP traffic for that option is monitored.

    For example, when Source IP address is empty, SMTP traffic from all sources is monitored.
