Configuring Adult Image Analysis in FortiMail

 Configuring a Content Profile and Scan Options

For this recipe we’ll need to briefly go over the content profile creation process. If you would like a more detailed explanation, see the content profile section in the FortiMail Administrator Guide.

To establish a content profie

1. Go to Profile > Content > Content.
2. Select New or edit an existing profile.
3. Select the appropriate domain from the Domain dropdown menu. Selecting “System” shows profiles from the entire FortiMail unit.
4. Enter a profile name.
5. Select “Reject” from the Action dropdown menu to make FortiMail reply to the SMTP client with SMTP reply code 550. All emails containing adult images will be rejected.
6. Enable video, audio, and image from the attachment scan rules. This will make sure that any attachments that contain adult images will be scanned for. 
7. Enable Adult image analysis under the Scan Options section.

Establishing Adult Image Analysis

With the content profile properly configured, we can now move on to configuring adult image analysis settings. 

1. Go to Security > Other > Adult Image Analysis. 
2. Enable the analysis.
3. Adjust the sensitivity of the ratting. Adjusting the sensitivity to the appropriate number will avoid false positives and false negatives.
4. Enter the minimum and maximum image size.
5. Select Apply.
