ClamAV3.5 is included in IPBrick. By default the service is inactive (Figure 3.50), to activate it just hit Modify and choose Yes at Enable configuration. When activated, ClamAV will filter all he incoming mail through its engine. When ClamAV detects a virus one of these possibilities may occur, and you can configure what to do (Figure 3.51):
Reject E-Mail: The message is rejected and will not enter the mail queue. The sender will receive a notification;
Mark E-Mail as virus: The message is marked and enter the mail queue normally;
Mark and Redirect E-Mail: The message is marked and redirected to a mail address;
Delete E-Mail: The message is deleted, will not enter the mail queue and no notification is sended.
Note: ClamAV will automatically update its database in a transparent way to the user.
