Blocking custom file extension is not working

That's because Windows determines file types based on the extension. Outlook sees .dll so figures "hmm, must be true". Linux uses the file command to determine what type of file it is, so recognizes that it isn't really a .dll.
MailScanner blocks on both filetype and filename - just add a new line in filename.rules.conf and you're set. I'd copy an existing line and edit to suit.

But the file is shown in outlook as a .dll
So is there a way to block this?
