it remove hostnames and IP addresses of your internal systems from the messages headers before they go out to other users for security purpose.
In a standard way each mail service add it's own hostname and IP address that helps trace the SMTP routing processes.
for example you should see this kind of entries in each mail header :
Received: from moutng.kundenserver.de (moutng.kundenserver.de
[212.227.17.10]) by mx.kundenserver.de (node=mxeu0) with ESMTP
(Nemesis) id 0Lxyxk-1Or9Lq3MqS-015L7K for This e-mail address is being protected from spambots. You need JavaScript enabled to view it ;
