How to block email with hoax image

We are facing spam emails with only one image in the body.

I've tryed to use the Security-->Other-->File Signiture, uploading the sha1 of the image ... but sadly this is used only in antivirus profile ... and from the documentation:

"Because not all attachment files are virus carriers, FortiMail file signature check only supports the following file types: .7z, .bat, .cab, .dll, .doc, .docm, .dotm, exe, .gz, .hta, .inf, .jar, .js, .jse, .msi, .msp, pdf, .pif, .potm, .ppam, .ppsm, .ppt, .pptm, .pptx, .reg, .scr, .sldm, .swf, .tar, .vbe, .ws, .wsc, .wsf, .wsh, .xlam, .xls, .xlsm, .xlsx, .xltm, .Z, and .zip files."

 

No image supported and no way to add more file types :(

 

Any ideas?

 

I'm using a 300D with v6.0,build126,181026 (6.0.3 GA)

 

THX,

Luca

    Feel free to DM me for my email so you can send me a sample and it can be added to our DB however try upgrading to 6.0.5 as there are enhancements to the Image Spam detection for automated detection for such spams.

    Carl ... I've read both 6.0.4 and 6.0.5 release notes but found nothing regarding "Image Spam detection" ... can you point me to some doc please?
