Network & Servers

We are in a process of decomissioning a handfull of Fujitsu Primergy Servers. Before of course, we want to make sure that the hard disks are completely wiped out.

I've setup the Antispam agents in Exchange 2013, but disabled most of the components. I do however, have the org-wide SCLJunkTheshold set to 4. I have a transport rule that is setting these borderl
