Blocking custom file extention is not working
Posted: 03 Feb 2016 13:24
Hi,
So I stumbled accross this site: http://www.emailsecuritycheck.net/index.html and had it sent it's test mails.
3 where blocked 4 came thru.
So to test I added this to the filename.rules at the bottem:
deny \.dll$ dll-files are not allowed dll-files are not allowed
deny \.()bat$ Possible malicious batch file script Batch files are often malicious
But it did not work.
Does anyone know what I did wrong?
Thx
