How do you embed/attach the file within mail?

The document was a Word document with the .docm extensiion. It contains a macro that is capable of executing commands once activated.

... and you didn't select something within SMTP policy / File Protection / MIME white list

no, no whitelisting

No Zero Day protection? 

I made a screenshot, does this answer your question:

What should i use?

Hi,

could you fix it?

I have similar issue with other extensions.

Nope, it stil doesn't seem to function correctly.

SFOS and UTM uses true file type detection by SAVI. Which means, the file will be analysed on multiple levels. 

You should create a feedback loop on the top, if you have a example file, which is not detected as you expect it should. 

LuCar Toni could you explain what you mean with the feedback loop and how to configure it, please?

Do you see this issue on V19.0 EAP, then create a feedback on the webadmin top right side.
If you are on V18.5, you should create a support case. 

ah ok, thank you. I'm on 18.5
