Configure Mail notification in SAP Knowledge management

Hi ,

I need to configure mail notification in SAP Knowledge management while end-user will upload files into particular folder structure which is known as Subscription service in KM.

There is one way to configure this from System administration ----system Configuration--->content management-->Utilities-->Channel originators where i can set email and SMS notification if any change will occur.

This will throw a notification MAIL or SMS which is active in system.

1) .If i'll change the email id in this channel originators then , is that mandatory to take restart of portal system to see effect of this change?

2). If i'll enable Subscription service for sending mail notification, then it'll affect server speed or some KM related services ?
