thats right. We want to block video and audio filetypes.
At the moment we use amavis in the shell version.
I've implemented a additionaly test to block the video and audio there.
I can see (sometimes), that users try to zip or rename the files.
But no chance because the check of filetypes.
I know also, that if the users make a password protected zip, the files go

Probably someone have a quick hack to add such a function?
