  2. On the Trend Micro Web Reputation configuration window, select the Security Level:
    • High– blocks a greater number of Web threats, but increases the risk of false positives.
      ScanMail monitors all messages for suspicious URLs, but there is a greater chance of false positives. False positives are email messages that ScanMail filters as containing dangerous URLs when they are actually legitimate.
    • Medium– blocks most Web threats while keeping the false positive count low.
      ScanMail monitors at a high level of detection with a moderate chance of filtering false positives.
    • Low– blocks fewer Web threats, but reduces the risk of false positives.
      ScanMail will only filter the most obvious and common Web threats and there is a very low chance that it will filter false positives.
  3. In the Action section, select the Action on unwanted messages: Pass, Quarantine, or Block.
  4. Select Stamp subject prefix, and then type a stamp label to add eye-catching notices or keywords in the subject header.
