File Access Control .exe files

Hi,

I have a problem with File Access Control. I want to block .exe Files, but I can not get it to work.

I have tried to set up a rule with the following settings:

I used the newest FileZilla.exe for testing. You can get it from here.

I also tried to use a more complex rule, which also does not work.

I used “File mime type does not match”:

/(image|application)\/(jpeg|png|pdf|zip|x-msdownload|exe|x-msinstaller|x-dosexec|octet-stream|vnd.openxmlformats-officedocument.wordprocessingml.document)$/i

This rule whitelists jpeg, png, pdf, zip and docx. But it does not whitelist exe files.

Has anybody else tried to use exe files with File Access Control? If so which mime-type did you use?

I have a similar topic about to block .mp4, and I have tried to set up a rule with the following settings
/^application/(video|mp4)$/i
