## Configuring Content Scanning Targets

### Procedure

1. Go to the Content Scanning screen by navigating to Spam Prevention → Content Scanning.
2. Click the Target tab.
3. Select a detection level:
   - High: This is the most rigorous level of spam detection. ScanMail monitors all email messages for suspicious files or text, but there is greater chance of false positives. False positives are those email messages that ScanMail filters as spam when they are actually legitimate email messages.
   - Medium: ScanMail monitors at a high level of spam detection with a moderate chance of filtering false positives.
   - Low: This is the default setting. This is most lenient level of spam detection. ScanMail will only filter the most obvious and common spam messages, but there is a very low chance that it will filter false positives.
4. Select Detect phishing to scan for phishing email messages.
5. Add addresses to the list of Approved Senders and Blocked Senders.
6. Click Save.
