## Enabling Content Scanning

ScanMail detects spam messages in real time and takes actions to protect Exchange clients. The approved senders list has higher priority than the blocked senders list. If an email address is in both the approved and blocked senders lists, ScanMail will not classify the email message as spam.

### Procedure

1. Go to the Content Scanning screen by navigating to Spam Prevention → Content Scanning.
2. Select Enable content scanning.
3. Click Save.
