antispam image-analysis
Use this command to configure thresholds for image scans.
When you configure a content profile, you can choose to scan images in the email body and attachments. You can fine-tune the file size that the FortiMail unit will scan, and how these images are detected. Separate thresholds exists for each category of images that you may want to block, such as violence or adult images.
