Block files from extension

Hi,

How can i block files from their extension ?

It's been a long time since using qmail-scanner.
There used to be a file named quarantine-attachments.txt where we can
insert, for example:

.exe 0

to block .exe files.

Now, it seems that this isn't the way anymore.

Can someone point me in the right direction, please ?

Any help would be appreciated.

Warm Regards,
