Configuring Adult Image Analysis in FortiMail


Maybe you suspect an employee of viewing adult images or videos during office hours through his or her email. Maybe you’re receiving unsolicited adult files through your email. In either scenario, FortiMail can help you keep your office setting professional through a new scanning option that detects if an email contains adult sensitive material.

In this recipe, we’ll guide you through the process of configuring a content profile to scan for adult images in the email body and attachments.


 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 ProfileContent Content.
  2. Select New or edit an existing profile.
  3. Select whether the profile is used system-wide or for a specific domain from the Domain dropdown menu. 
  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 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.
