This HOWTO it's for sep 11 and aplicable for Exchange until 2007 SP1.
I use SEP 12.1 RU1 and Exchange 2010 SP2
To configure exceptions I use this guide: http://technet.microsoft.com/en-us/library/bb332342.aspx
this site have 4 servers and install path isn't the same on each server.....
on SEP 11 I was able to type % in the field, now in 12.1 I can't....
don't have a .txt or .cfg or .ini.... with this pre set variables that I can edit to add the variable that I need???
