Blocking custom file extension is not working

[Denis Beauchemin]

Peter,

The first one should work as long as you separated each field with TABs (not spaces). You also have to reload/restart MailScanner.

The second one looks strange with its “()”. What are you trying to block exactly with that?

Objet : Blocking custom file extension is not working

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
