Blocking custom file extension is not working

[Richard Mealing]

I would think you need to escape the special characters -

deny \.\(\)bat$ Possible malicious batch file script               Batch files are often malicious

Hi,

So I want to block .dll and .()bat but mailscanner is not doing it.
I added this to the filename.rules at the bottom:
deny \.dll$ dll-files are not allowed         dll-files are not allowed
deny \.()bat$ Possible malicious batch file script               Batch files are often malicious

Regards,
Pieter Goris
